本发明涉及浓缩机，具体是一种浓缩机高效运行控制方法，以及高效浓缩机。The invention relates to a concentrator, in particular to a concentrator high-efficiency operation control method and a high-efficiency concentrator.
背景技术Background technique
浓缩机用作浆料的浓缩和澄清处理，其被广泛应用于选矿、冶金、化工、煤炭、建材、环保等行业。Concentrators are used for concentrating and clarifying slurries and are widely used in mineral processing, metallurgy, chemical industry, coal, building materials, environmental protection and other industries.
浓缩机主要由壳体以及布置在壳体上的进料系统、反冲系统（通常为进气系统）、排液系统、料仓斗和若干块过滤板组成；每块过滤板为具有过滤腔的中空结构，且每块过滤板的过滤腔具有流体端口，过滤板通过流体端口接通反冲系统和排液系统。其运行控制过程是，进料系统将待浓缩浆料送入壳体内、并处在过滤板的外部，在压力作用下，各过滤板将壳体内的浆料进行固、液分离，分离出的滤液经过滤板上的过滤腔、流体端口进入排液系统而排出壳体，固体部分粘附在过滤板上；当过滤板上堆积的滤饼至一定厚度而影响过滤板的固、液分离功能时，需要启动反冲系统，由反冲系统的反冲介质（通常为压缩空气）经流体端口而进入过滤板的过滤腔内反冲过滤板，使过滤板表面粘附的滤饼被剥离而落入料仓斗内，按照对浆料浓缩浓度的要求而开启料仓斗实现卸料；基于过滤板与反冲系统和排液系统的连接配合关系，为了避免反冲系统的反冲介质进入排液系统而影响反冲效果、以及为了避免滤液进入反冲系统内而影响反冲系统的正常运行，浓缩机上的反冲系统和排液系统的控制是保持互锁状态的，即当反冲系统启动时排液系统进液端须关闭，当排液系统启动时反冲系统出口端须关闭。The concentrator is mainly composed of a shell and a feed system, a backwash system (usually an air intake system), a drainage system, a silo hopper and several filter plates arranged on the shell; each filter plate is a hollow structure with a filter cavity, and the filter cavity of each filter plate has a fluid port, and the filter plate is connected to the backwash system and the drainage system through the fluid port. Its operation control process is that the feed system sends the slurry to be concentrated into the shell and is outside the filter plate. Under the action of pressure, each filter plate separates the slurry in the shell from solid and liquid. The separated filtrate enters the drainage system through the filter cavity and fluid port on the filter plate and is discharged from the shell, and the solid part adheres to the filter plate; when the filter cake accumulated on the filter plate reaches a certain thickness and affects the solid-liquid separation function of the filter plate, it is necessary to start the backwash system, and the backwash medium of the backwash system (usually compressed air) enters the filter cavity of the filter plate through the fluid port to backwash the filter plate, so that The filter cake adhered to the surface of the filter plate is peeled off and falls into the silo bucket, and the silo bucket is opened to unload according to the requirements of the slurry concentration. Based on the connection and coordination between the filter plate, the backwashing system and the drainage system, in order to avoid the backwashing medium of the backwashing system entering the drainage system and affecting the backwashing effect, and to avoid the filtrate entering the backwashing system and affecting the normal operation of the backwashing system, the control of the backwashing system and the drainage system on the concentrator is kept in an interlocked state, that is, when the backwashing system is started, the liquid inlet end of the drainage system must be closed, and when the drainage system is started, the outlet end of the backwashing system must be closed.
由上述浓缩机的运行控制过程可以看出，其在滤饼剥离时需要向壳体内注入反冲压力、且排液系统是关闭的，如此，进料系统必须停止进料而等待滤饼剥离完毕再行进料，且在滤饼剥离时需要在壳体上形成卸压点-即料仓斗的开启，也就是说，上述浓缩机在滤饼剥离时需要停止进料且在壳体上开启料仓斗，如此才能实现反冲。毫无疑问的，此种浓缩机因进料的间歇式而使得浓缩效率低，另外，开启料仓斗的卸压方式使得浓缩出的浆料浓度有限，不能直接实现高浓度浆料的浓缩处理，整体运行经济性差。It can be seen from the operation control process of the above-mentioned concentrator that it is necessary to inject recoil pressure into the shell when the filter cake is peeled off, and the drainage system is closed. In this way, the feeding system must stop feeding and wait for the filter cake to be peeled off before feeding again, and a pressure relief point needs to be formed on the shell when the filter cake is peeled off, that is, the opening of the silo hopper. In other words, the above-mentioned concentrator needs to stop feeding and open the silo hopper on the shell when the filter cake is peeled off, so as to achieve recoil. Undoubtedly, this kind of concentrator has low concentration efficiency due to the intermittent feeding. In addition, the pressure relief method of opening the silo hopper makes the concentrated slurry concentration limited, and it is not possible to directly achieve the concentration treatment of high-concentration slurry, and the overall operation economy is poor.

The main technical content of the present invention is described in detail with multiple embodiments below. Among them, embodiment 1 is combined with the accompanying drawings of the specification, that is, Figure 1, to provide a detailed and specific description of the content of the present invention. Other embodiments do not have separate drawings, but their main structures can still refer to the drawings of embodiment 1. It should be particularly noted that the drawings of the present invention are schematic, and unnecessary details have been simplified in order to clarify the technical purpose of the present invention, so as to avoid blurring the technical solution of the present invention's contribution to the prior art.
实施例1Example 1
本发明的浓缩机高效运行控制方法是基于对浓缩机的结构改变而实现，其采取的工艺措施是：The efficient operation control method of the concentrator of the present invention is realized based on the structural change of the concentrator, and the process measures taken are:
-将浓缩机内的所有过滤板分为多组，该分组是将浓缩机内连续排布的多块（通常在十块以内）过滤板分为一组，从而使浓缩机内的所有过滤板被划分为多个过滤板组；与之对应的，将浓缩机底部的料仓斗按照过滤板的分组而分为多个，使每个料仓斗处在对应过滤板组的下方，各料仓斗的启、闭能够独立控制；- All filter plates in the concentrator are divided into multiple groups. The grouping is to group multiple (usually less than ten) filter plates arranged continuously in the concentrator into one group, so that all filter plates in the concentrator are divided into multiple filter plate groups; correspondingly, the silo hopper at the bottom of the concentrator is divided into multiple groups according to the grouping of the filter plates, so that each silo hopper is located below the corresponding filter plate group, and the opening and closing of each silo hopper can be independently controlled;
-每一过滤板组连接有能够独立控制的反冲系统和排液系统，且每一过滤板组的反冲系统和排液系统的控制保持互锁状态；也就是说，各过滤板组的反冲系统控制是相互独立的，同样的，各过滤板组的排液系统控制亦是相互独立的，但是，要求同一过滤板组的反冲系统和排液系统的控制需要保持互锁状态；- Each filter plate group is connected to an independently controllable backflushing system and drainage system, and the backflushing system and drainage system of each filter plate group are controlled in an interlocked state; that is, the backflushing system control of each filter plate group is independent of each other, and similarly, the drainage system control of each filter plate group is also independent of each other, but the backflushing system and drainage system control of the same filter plate group need to be kept in an interlocked state;
-在浓缩机的持续进料过程中，各过滤板组分别通过各自的排液系统将滤液排出；当各过滤板组上分别堆积形成滤饼使，按照不同的前、后顺序对各过滤板组分别通过各自的反冲系统进行滤饼剥离，也就是说，浓缩机内的各过滤板组不得在同时进行反冲动作。- During the continuous feeding process of the concentrator, each filter plate group discharges the filtrate through its own drainage system; when filter cakes are accumulated on each filter plate group, the filter cakes are peeled off from each filter plate group through its own backwashing system in different front and back orders, that is, the filter plate groups in the concentrator shall not be backwashed at the same time.
将上述浓缩机高效运行控制方法转化到浓缩机的结构设计上，可形成本发明的高效浓缩机。By converting the above-mentioned concentrator efficient operation control method into the structural design of the concentrator, a high-efficiency concentrator of the present invention can be formed.
参见图1所示，本发明的高效浓缩机包括壳体1、以及布置在壳体1上的进料管2、排液管10和反冲管7。As shown in FIG. 1 , the high-efficiency concentrator of the present invention includes a housing 1 , and a feed pipe 2 , a liquid discharge pipe 10 and a backwash pipe 7 arranged on the housing 1 .
其中，壳体1在机架上卧式放置，在壳体1内顶部沿着壳体1的长度方向而固定有多段流体引导腔3，这些流体引导腔3保持相互独立。每段流体引导腔3上连接有能够延伸出壳体1的出液管接头5和反冲管接头4；出液管接头5带有独立的控制阀门，反冲管接头4亦带有独立的控制阀门，但是，要求同一段流体引导腔3所连接的反冲管接头4和出液管接头5的控制阀门为互锁状态，即反冲管接头4导通时则出液管接头5关闭，反之，出液管接头5导通时则反冲管接头4关闭。The housing 1 is placed horizontally on the frame, and multiple sections of fluid guide chambers 3 are fixed at the top of the housing 1 along the length direction of the housing 1, and these fluid guide chambers 3 remain independent of each other. Each section of the fluid guide chamber 3 is connected with a liquid outlet pipe joint 5 and a backwash pipe joint 4 that can extend out of the housing 1; the liquid outlet pipe joint 5 has an independent control valve, and the backwash pipe joint 4 also has an independent control valve, but the control valves of the backwash pipe joint 4 and the liquid outlet pipe joint 5 connected to the same section of the fluid guide chamber 3 are required to be in an interlocked state, that is, when the backwash pipe joint 4 is turned on, the liquid outlet pipe joint 5 is closed, and vice versa, when the liquid outlet pipe joint 5 is turned on, the backwash pipe joint 4 is closed.
壳体1内沿着长度方向而顺序排布有若干块过滤板6。每块过滤板6主要由板框、以及固定在板框至少一侧（通常是两侧）的筋板、包覆在筋板上的过滤膜/过滤布组成，板框和筋板组成能够排出滤液的过滤腔，筋板上开设有若干个与过滤腔相通的滤液通道，可见每块过滤板6为具有过滤腔的中空结构；此外，每块过滤板6的板框顶部开设有供滤液或反冲介质流动的流体端口8。壳体1内的所有过滤板6对应上述壳体1上的各段流体引导腔3而分为多组，即对应每一段流体引导腔3而将连续排布的多块（通常在十块以内）过滤板6分为一组，每一过滤板组以其各过滤板6上的流体端口8接通对应流体引导腔3，即流体引导腔3将对应配合的各块过滤板6通过它们的流体端口8串联在一起，如此，对应各段流体引导腔3而将浓缩机内的所有过滤板6划分为多个过滤板组。Several filter plates 6 are arranged in sequence along the length direction in the housing 1. Each filter plate 6 is mainly composed of a plate frame, a rib plate fixed on at least one side (usually both sides) of the plate frame, and a filter membrane/filter cloth wrapped on the rib plate. The plate frame and the rib plate form a filter cavity that can discharge filtrate. The rib plate is provided with a plurality of filtrate channels communicating with the filter cavity. It can be seen that each filter plate 6 is a hollow structure with a filter cavity; in addition, a fluid port 8 for the flow of filtrate or backwash medium is provided on the top of the plate frame of each filter plate 6. All filter plates 6 in the housing 1 are divided into multiple groups corresponding to each section of the fluid guide cavity 3 on the housing 1, that is, corresponding to each section of the fluid guide cavity 3, a plurality of filter plates 6 (usually within ten) arranged in a row are divided into a group, and each filter plate group is connected to the corresponding fluid guide cavity 3 by the fluid port 8 on each filter plate 6, that is, the fluid guide cavity 3 connects the corresponding matching filter plates 6 in series through their fluid ports 8. In this way, corresponding to each section of the fluid guide cavity 3, all filter plates 6 in the concentrator are divided into multiple filter plate groups.
壳体1的底部连接有多个向下延伸的料仓斗9，这些料仓斗9的数量和位置与壳体1内分出的过滤板组数量和位置相对应。具体是，壳体1底部所连接的料仓斗9对应上述壳体1上的各段流体引导腔3而分为多个，每个料仓斗9处在对应流体引导腔3的下方，每个料仓斗9的卸料阀门启、闭能够独立控制。The bottom of the housing 1 is connected to a plurality of silo hoppers 9 extending downward, and the number and position of these silo hoppers 9 correspond to the number and position of the filter plate groups separated in the housing 1. Specifically, the silo hoppers 9 connected to the bottom of the housing 1 are divided into a plurality of silo hoppers corresponding to the various sections of the fluid guide chambers 3 on the housing 1, and each silo hopper 9 is located below the corresponding fluid guide chamber 3, and the opening and closing of the discharge valve of each silo hopper 9 can be independently controlled.
进料管2用作将待浓缩的浆料送入壳体1内，进入壳体1内的浆料浸泡在壳体1内的各过滤板6的外部。在压力作用各过滤板6对浆料进行固、液分离，分离出的滤液进入过滤板6的过滤腔内，并经流体端口8进入对应的流体引导腔3内，分离出的滤渣粘附在过滤板6的过滤膜/过滤布表面、部分滤渣会因重力而自行沉淀。The feed pipe 2 is used to feed the slurry to be concentrated into the housing 1. The slurry entering the housing 1 is soaked in the outside of each filter plate 6 in the housing 1. Under the action of pressure, each filter plate 6 separates the solid and liquid of the slurry. The separated filtrate enters the filter cavity of the filter plate 6 and enters the corresponding fluid guide cavity 3 through the fluid port 8. The separated filter residue adheres to the filter membrane/filter cloth surface of the filter plate 6, and part of the filter residue will settle by itself due to gravity.
排液管10与上述壳体1上的各段流体引导腔3所连接的出液管接头5相接通，即各段流体引导腔3上的、带有控制阀门的出液管接头5能够与排液管10相接通，各段流体引导腔3内的滤液经出液管接头5进入排液管10内。The drain pipe 10 is connected to the liquid outlet pipe joint 5 connected to each section of the fluid guiding cavity 3 on the above-mentioned shell 1, that is, the liquid outlet pipe joint 5 with the control valve on each section of the fluid guiding cavity 3 can be connected to the drain pipe 10, and the filtrate in each section of the fluid guiding cavity 3 enters the drain pipe 10 through the liquid outlet pipe joint 5.
反冲管7与上述壳体1上的各段流体引导腔3所连接的反冲管接头4相接通，即各段流体引导腔3上的、带有控制阀门的反冲管接头4能够与反冲管7相接通，反冲管7的反冲介质（通常是压缩空气，当然还可以是高压水或者气水混合物）经各段流体引导腔3上的对应反冲管接头4而进入对应流体引导腔3内。The recoil pipe 7 is connected to the recoil pipe joints 4 connected to each section of the fluid guiding cavity 3 on the above-mentioned shell 1, that is, the recoil pipe joints 4 with control valves on each section of the fluid guiding cavity 3 can be connected to the recoil pipe 7, and the recoil medium of the recoil pipe 7 (usually compressed air, of course, it can also be high-pressure water or an air-water mixture) enters the corresponding fluid guiding cavity 3 through the corresponding recoil pipe joints 4 on each section of the fluid guiding cavity 3.
本发明的高效浓缩机的运行控制过程是：The operation control process of the high-efficiency concentrator of the present invention is:
-启动进料管2向壳体1内持续进料，壳体1内的浆料在压力作用下，通过各过滤板6进行固、液分离；分离出的滤液经过滤板6上的过滤腔、流体端口8和对应的流体引导腔3而进入排液管10内排出壳体1，分离出的部分固体在壳体1内自行沉淀进入对应料仓斗9内，另部分固体粘附在过滤板6上；- Start the feed pipe 2 to continuously feed the material into the housing 1. The slurry in the housing 1 is separated into solid and liquid through the filter plates 6 under pressure. The separated filtrate enters the discharge pipe 10 through the filter cavity, fluid port 8 and corresponding fluid guide cavity 3 on the filter plate 6 and is discharged from the housing 1. Part of the separated solids are precipitated in the housing 1 and enter the corresponding silo 9, while the other part of the solids adhere to the filter plate 6.
-当某一过滤板组上堆积的滤饼至一定厚度而影响过滤板6的固、液分离功能时，关闭该当前过滤板组的出液控制阀门，开启该当前过滤板组的反冲控制阀门，由反冲管7的反冲介质经对应流体引导腔3和各流体端口8而进入对应过滤板6的过滤腔内，反冲过滤板6，使过滤板6表面粘附的滤饼被剥离而落入对应料仓斗9内，反冲介质经当前处于固、液分离的其它各过滤板组而排出壳体1；- When the filter cake accumulated on a certain filter plate group reaches a certain thickness and affects the solid-liquid separation function of the filter plate 6, the liquid outlet control valve of the current filter plate group is closed, and the backwash control valve of the current filter plate group is opened, and the backwash medium from the backwash pipe 7 enters the filter cavity of the corresponding filter plate 6 through the corresponding fluid guide cavity 3 and each fluid port 8, backwashes the filter plate 6, and causes the filter cake adhered to the surface of the filter plate 6 to be peeled off and fall into the corresponding silo 9, and the backwash medium is discharged from the housing 1 through the other filter plate groups currently in the solid-liquid separation;
-按照对浆料浓缩浓度的要求而开启对应料仓斗9，实现卸料。- Open the corresponding silo hopper 9 according to the requirement of slurry concentration to achieve unloading.

本发明的浓缩机高效运行控制方法是基于对浓缩机的结构改变而实现，其采取的工艺措施是：The efficient operation control method of the concentrator of the present invention is realized based on the structural change of the concentrator, and the process measures taken are:
-将浓缩机内的所有过滤板分为多组，该分组是将浓缩机内连续排布的多块（通常在十块以内）过滤板分为一组，从而使浓缩机内的所有过滤板被划分为多个过滤板组；与之对应的，将浓缩机底部的料仓斗按照过滤板的分组而分为多个，使每个料仓斗处在对应过滤板组的下方，各料仓斗的启、闭能够独立控制；- All filter plates in the concentrator are divided into multiple groups. The grouping is to group multiple (usually less than ten) filter plates arranged continuously in the concentrator into one group, so that all filter plates in the concentrator are divided into multiple filter plate groups; correspondingly, the silo hopper at the bottom of the concentrator is divided into multiple groups according to the grouping of the filter plates, so that each silo hopper is located below the corresponding filter plate group, and the opening and closing of each silo hopper can be independently controlled;
-每一过滤板组连接有能够独立控制的反冲系统和排液系统，且每一过滤板组的反冲系统和排液系统的控制保持互锁状态；也就是说，各过滤板组的反冲系统控制是相互独立的，同样的，各过滤板组的排液系统控制亦是相互独立的，但是，要求同一过滤板组的反冲系统和排液系统的控制需要保持互锁状态；- Each filter plate group is connected to an independently controllable backflushing system and drainage system, and the backflushing system and drainage system of each filter plate group are controlled in an interlocked state; that is, the backflushing system control of each filter plate group is independent of each other, and similarly, the drainage system control of each filter plate group is also independent of each other, but the backflushing system and drainage system control of the same filter plate group need to be kept in an interlocked state;
-在浓缩机的持续进料过程中，各过滤板组分别通过各自的排液系统将滤液排出；当各过滤板组上分别堆积形成滤饼使，按照不同的前、后顺序对各过滤板组分别通过各自的反冲系统进行滤饼剥离，也就是说，浓缩机内的各过滤板组不得在同时进行反冲动作。- During the continuous feeding process of the concentrator, each filter plate group discharges the filtrate through its own drainage system; when filter cakes are accumulated on each filter plate group, the filter cakes are peeled off from each filter plate group through its own backwashing system in different front and back orders, that is, the filter plate groups in the concentrator shall not be backwashed at the same time.
将上述浓缩机高效运行控制方法转化到浓缩机的结构设计上，可形成本发明的高效浓缩机。By converting the above-mentioned concentrator efficient operation control method into the structural design of the concentrator, a high-efficiency concentrator of the present invention can be formed.
本发明的高效浓缩机包括壳体、以及布置在壳体上的进料管、排液管和反冲管。The high-efficiency concentrator of the present invention comprises a shell, and a feed pipe, a liquid discharge pipe and a backwash pipe arranged on the shell.
其中，壳体在机架上卧式放置。壳体内沿着长度方向而顺序排布有若干块过滤板。每块过滤板主要由板框、以及固定在板框至少一侧（通常是两侧）的筋板、包覆在筋板上的过滤膜/过滤布组成，板框和筋板组成能够排出滤液的过滤腔，筋板上开设有若干个与过滤腔相通的滤液通道，可见每块过滤板为具有过滤腔的中空结构；此外，每块过滤板的板框顶部开设有供滤液或反冲介质流动的流体端口。壳体内的所有过滤板分为多组，每一组为连续排布的多块（通常在十块以内）过滤板组成，如此，将浓缩机内的所有过滤板划分为多个过滤板组；每一过滤板组的各过滤板通过各自流体端口而连接有能够延伸出壳体的出液管接头和反冲管接头，每一过滤板组的各出液管接头分别带有控制阀门，且每一过滤板组的各出液管接头的控制阀门能够同步控制，每一过滤板组的各反冲管接头亦分别带有控制阀门，且每一过滤板组的各反冲管接头的控制阀门能够同步控制，但是，要求同一过滤板组所连接的反冲管接头和出液管接头的控制阀门为互锁状态，即当同一过滤板组的各反冲管接头导通时、则各出液管接头关闭，反之，当同一过滤板组的各出液管接头导通时、则各反冲管接头关闭。The shell is placed horizontally on the frame. Several filter plates are arranged in sequence along the length direction in the shell. Each filter plate is mainly composed of a plate frame, a rib plate fixed on at least one side (usually both sides) of the plate frame, and a filter membrane/filter cloth wrapped on the rib plate. The plate frame and the rib plate form a filter cavity that can discharge the filtrate. The rib plate is provided with several filtrate channels communicating with the filter cavity. It can be seen that each filter plate is a hollow structure with a filter cavity; in addition, a fluid port for the flow of filtrate or backwash medium is provided on the top of the plate frame of each filter plate. All filter plates in the shell are divided into multiple groups, each group is composed of multiple (usually less than ten) filter plates arranged continuously, so that all filter plates in the concentrator are divided into multiple filter plate groups; each filter plate of each filter plate group is connected to a liquid outlet pipe joint and a backwash pipe joint that can extend out of the shell through its own fluid port, each liquid outlet pipe joint of each filter plate group is respectively provided with a control valve, and the control valve of each liquid outlet pipe joint of each filter plate group can be controlled synchronously, each backwash pipe joint of each filter plate group is also respectively provided with a control valve, and the control valve of each backwash pipe joint of each filter plate group can be controlled synchronously, but it is required that the control valves of the backwash pipe joint and the liquid outlet pipe joint connected to the same filter plate group are in an interlocked state, that is, when each backwash pipe joint of the same filter plate group is connected, each liquid outlet pipe joint is closed, and vice versa, when each liquid outlet pipe joint of the same filter plate group is connected, each backwash pipe joint is closed.
壳体的底部连接有多个向下延伸的料仓斗，这些料仓斗的数量和位置与壳体内分出的过滤板组数量和位置相对应。具体是，壳体底部所连接的料仓斗对应上述壳体上的各过滤板组而分为多个，每个料仓斗处在对应过滤板组的下方，每个料仓斗的卸料阀门启、闭能够独立控制。The bottom of the shell is connected to a plurality of silo hoppers extending downward, and the number and position of these silo hoppers correspond to the number and position of the filter plate groups separated in the shell. Specifically, the silo hoppers connected to the bottom of the shell are divided into a plurality of silo hoppers corresponding to the filter plate groups on the shell, and each silo hopper is located below the corresponding filter plate group, and the opening and closing of the discharge valve of each silo hopper can be independently controlled.
进料管用作将待浓缩的浆料送入壳体内，进入壳体内的浆料浸泡在壳体内的各过滤板的外部。在压力作用各过滤板对浆料进行固、液分离，分离出的滤液进入过滤板的过滤腔内，并经流体端口进入对应出液管接头内，分离出的滤渣粘附在过滤板的过滤膜/过滤布表面、部分滤渣会因重力而自行沉淀。The feed pipe is used to deliver the slurry to be concentrated into the shell. The slurry entering the shell is soaked in the outside of each filter plate in the shell. Under the action of pressure, each filter plate separates the solid and liquid of the slurry. The separated filtrate enters the filter cavity of the filter plate and enters the corresponding liquid outlet pipe joint through the fluid port. The separated filter residue adheres to the filter membrane/filter cloth surface of the filter plate, and part of the filter residue will settle by itself due to gravity.
排液管与上述壳体上的各过滤板组所连接的各出液管接头相接通，即各过滤板组上的、带有控制阀门的出液管接头能够与排液管相接通，各过滤板组分离出的滤液经各自的多个出液管接头进入排液管内。The drain pipe is connected to the liquid outlet pipe joints connected to the filter plate groups on the above-mentioned shell, that is, the liquid outlet pipe joints with control valves on each filter plate group can be connected to the drain pipe, and the filtrate separated by each filter plate group enters the drain pipe through its own multiple liquid outlet pipe joints.
反冲管与上述壳体上的各过滤板组所连接的反冲管接头相接通，即各过滤板组上的、带有控制阀门的反冲管接头能够与反冲管相接通，反冲管的反冲介质（通常是压缩空气，当然还可以是高压水或者气水混合物）经各过滤板组上的多个对应反冲管接头而进入对应过滤板组内。The recoil pipe is connected to the recoil pipe joints connected to each filter plate group on the above-mentioned shell, that is, the recoil pipe joints with control valves on each filter plate group can be connected to the recoil pipe, and the recoil medium of the recoil pipe (usually compressed air, of course, it can also be high-pressure water or a gas-water mixture) enters the corresponding filter plate group through multiple corresponding recoil pipe joints on each filter plate group.
本发明的高效浓缩机的运行控制过程是：The operation control process of the high-efficiency concentrator of the present invention is:
-启动进料管向壳体内持续进料，壳体内的浆料在压力作用下，通过各过滤板进行固、液分离；分离出的滤液经过滤板上的过滤腔、流体端口和对应的出液管接头而进入排液管内、排出壳体，分离出的部分固体在壳体内自行沉淀进入对应料仓斗内，另部分固体粘附在过滤板上；- Start the feed pipe to continuously feed into the shell. Under the action of pressure, the slurry in the shell is separated into solid and liquid through each filter plate. The separated filtrate enters the discharge pipe and is discharged from the shell through the filter cavity, fluid port and corresponding liquid outlet pipe joint on the filter plate. Part of the separated solids settle in the shell and enter the corresponding silo hopper, while the other part of the solids adhere to the filter plate.
-当某一过滤板组上堆积的滤饼至一定厚度而影响过滤板的固、液分离功能时，关闭该当前过滤板组的出液控制阀门，开启该当前过滤板组的反冲控制阀门，由反冲管的反冲介质经对应反冲管接头和流体端口而进入对应过滤板的过滤腔内，反冲过滤板，使过滤板表面粘附的滤饼被剥离而落入对应料仓斗内，反冲介质经当前处于固、液分离的其它各过滤板组而排出壳体；-When the filter cake accumulated on a certain filter plate group reaches a certain thickness and affects the solid-liquid separation function of the filter plate, close the liquid outlet control valve of the current filter plate group, open the backwash control valve of the current filter plate group, and the backwash medium of the backwash pipe enters the filter cavity of the corresponding filter plate through the corresponding backwash pipe joint and fluid port, backwash the filter plate, so that the filter cake adhered to the surface of the filter plate is peeled off and falls into the corresponding silo bucket, and the backwash medium is discharged from the shell through other filter plate groups currently in solid-liquid separation;
-按照对浆料浓缩浓度的要求而开启对应料仓斗，实现卸料。-Open the corresponding silo hopper according to the requirements of slurry concentration to achieve unloading.
