玻璃清洁为玻璃包装出厂前的最后一道工序，厂家通常采用玻璃清洗机将玻璃表面的切割碎屑及灰尘毛屑冲洗干净，冲洗流程有两道，第一道冲洗主要是为了冲刷异物，经过海绵辊清洁的玻璃进入第二道冲洗，第二道冲洗需要使用纯水进行清洁，清洁后的玻璃传送到风机下方，风机将玻璃表面的水膜吹下使玻璃表面干爽洁净，至此玻璃清洁流程完成。Glass cleaning is the last process before glass packaging leaves the factory. Manufacturers usually use glass cleaning machines to rinse off cutting debris, dust and hair on the glass surface. There are two rinse processes. The first rinse is mainly to flush out foreign matter. The glass cleaned by the sponge roller enters the second rinse. The second rinse requires the use of pure water for cleaning. The cleaned glass is conveyed to the bottom of the fan. The fan blows off the water film on the glass surface to make the glass surface dry and clean. At this point, the glass cleaning process is completed.

现有的清洁工序的用水量巨大，为循环用水提高水资源利用率，一般采用反渗透膜对废水进行过滤，长时间工作后，沉积的大量杂质泥沙等覆盖反渗透膜，导致反渗透膜的过滤效果下降影响水处理效率，因此为解决现有技术存在的问题亟需一种新的改进方案。The existing cleaning process consumes a huge amount of water. In order to recycle water and improve water resource utilization, a reverse osmosis membrane is generally used to filter wastewater. After working for a long time, a large amount of deposited impurities and sand cover the reverse osmosis membrane, resulting in a decrease in the filtering effect of the reverse osmosis membrane and affecting the water treatment efficiency. Therefore, a new improvement plan is urgently needed to solve the problems existing in the existing technology.

本发明的目的在于提供废水清洁循环装置，以排出反渗透膜外积压的泥沙杂质，提高废水循环处理效率。The object of the present invention is to provide a wastewater cleaning circulation device to discharge the sediment impurities accumulated outside the reverse osmosis membrane and improve the wastewater circulation treatment efficiency.

本发明的基础方案为：废水清洁循环装置，包括箱体、进水口和出水口，箱体内设有过滤单元和搅拌单元；The basic scheme of the present invention is: a wastewater cleaning circulation device, comprising a box body, a water inlet and a water outlet, wherein a filtering unit and a stirring unit are arranged in the box body;

过滤单元包括膜反渗透膜和活塞，活塞滑动连接在箱体内壁，活塞上方连接气缸，通过气缸可推动活塞在箱体内上下滑动，反渗透膜以箱体中轴为界对称嵌入箱体的侧壁；The filtration unit includes a reverse osmosis membrane and a piston. The piston is slidably connected to the inner wall of the box. The piston is connected to a cylinder above the piston. The piston can be pushed to slide up and down in the box through the cylinder. The reverse osmosis membrane is symmetrically embedded in the side wall of the box with the central axis of the box as the boundary.

搅拌单元包括搅拌辊和叶片，搅拌棍轴向竖直且其两端转动连接在箱体的上下内壁，搅拌辊与活塞螺纹连接，搅拌辊下端通过花键套有单向轴承，花键外部转动连接有限位环，限位环固定在活塞下方，单向轴承外连接叶片；The stirring unit includes a stirring roller and blades. The stirring roller is axially vertical and its two ends are rotatably connected to the upper and lower inner walls of the box body. The stirring roller is threadedly connected to the piston. The lower end of the stirring roller is provided with a one-way bearing through a spline sleeve. The outer side of the spline is rotatably connected to a limit ring. The limit ring is fixed under the piston. The one-way bearing is externally connected to the blades.

单向轴承与叶片之间竖直穿有销轴，销轴包括水平段与竖直段，销轴竖直段的上端限位在叶片顶部，单向轴承底部开设有凹槽，销轴的水平段的端部可插入凹槽内；反渗透膜下方的箱体侧壁内对称开两个出水口。A pin shaft is vertically passed through the one-way bearing and the blade, and the pin shaft includes a horizontal section and a vertical section. The upper end of the vertical section of the pin shaft is limited at the top of the blade. A groove is provided at the bottom of the one-way bearing, and the end of the horizontal section of the pin shaft can be inserted into the groove; two water outlets are symmetrically opened in the side wall of the box below the reverse osmosis membrane.

本基础方案的有益效果为：The beneficial effects of this basic scheme are:

1、反渗透膜设置在箱体侧方，通过活塞向下移动挤压废水，废水经过反渗透膜并从箱体两侧排出，与通常水平设置的反渗透膜相比，避免泥沙杂质直接沉降在反渗透膜表面。1. The reverse osmosis membrane is set on the side of the box. The piston moves downward to squeeze the wastewater. The wastewater passes through the reverse osmosis membrane and is discharged from both sides of the box. Compared with the reverse osmosis membrane usually set horizontally, it avoids the sediment impurities from settling directly on the surface of the reverse osmosis membrane.

2、利用单向轴承特性使得叶片只能在活塞上移时跟随转动，同时采用浮力控制的销轴控制叶片与搅拌辊的连通，只有位于废水内叶片才能随搅拌辊转动，当箱体内废水排出后，叶片不转动。2. The one-way bearing characteristics are used to ensure that the blades can only rotate when the piston moves upward. At the same time, a buoyancy-controlled pin is used to control the connection between the blades and the stirring roller. Only the blades in the wastewater can rotate with the stirring roller. When the wastewater in the box is discharged, the blades do not rotate.

3、采用叶片搅拌时产生的离心力将射频芯片向外甩出，射频芯片感应射频控制阀门打开，同时叶片搅拌将箱体底部沉积的泥沙杂质推动至出水口排出。3. The centrifugal force generated by the blade stirring is used to throw the RF chip outward. The RF chip senses the RF control valve to open. At the same time, the blade stirring pushes the sediment impurities deposited at the bottom of the box to the water outlet for discharge.

The valve control unit includes a switch, an airbag, a third spring, and a pressure block. The switch is fixed to the side wall of the box body.

An airbag is fixed on the other side of the pressure block. The space between the box body and the piston is set as the second cavity, and the airbag is connected to the second cavity. A second water outlet is opened at the center axis of the bottom of the box body. The second water outlet is electrically connected to the switch through the controller. When the piston moves upward, the airbag expands, pushing the pressure block to press the switch to open the second water outlet. When the piston moves downward, the airbag shrinks, and the pressure block leaves the switch to close the second water outlet. The residual wastewater is discharged through the second water outlet at the center axis of the bottom of the box body.

实施例基本如附图1所示：The embodiment is basically as shown in Figure 1:

废水清洁循环装置，如图1所示，包括箱体1、进水口2和出水口3，进水口2外设有进水阀门76，进水阀门76与控制器电连接。箱体1内设置过滤单元、搅拌单元。过滤单元包括反渗透膜41和活塞42，活塞42水平设置且滑动连接在箱体1内壁，活塞42上方连接气缸43的输出轴，气缸43可推动活塞42在箱体1内上下滑动，气缸43设有两个并沿活塞42中轴对称设置，有利于活塞42的稳定运动。反渗透膜41以箱体1中轴为界对称嵌入箱体1的侧壁，废水可通过反渗透膜41过滤杂质并向箱体1外侧排出，靠近叶片52的反渗透膜41一侧的外部安装滤网77，滤网77平行于反渗透膜41设置且与箱体1滑动连接，滤网77内部插有活性炭与PP棉隔层。当活塞42沿箱体1内壁向下运动时，废水被挤压并通过滤网77及反渗透膜41转变为循环水，循环水将再次用于玻璃清洁。与通常水平设置的反渗透反渗透膜41相比，本方案中的反渗透膜41设置在侧壁可避免泥沙杂质直接沉降在反渗透膜41表面。The wastewater cleaning circulation device, as shown in FIG1 , comprises a housing 1, a water inlet 2 and a water outlet 3, and a water inlet valve 76 is arranged outside the water inlet 2, and the water inlet valve 76 is electrically connected to the controller. A filtering unit and a stirring unit are arranged in the housing 1. The filtering unit comprises a reverse osmosis membrane 41 and a piston 42, the piston 42 is arranged horizontally and slidably connected to the inner wall of the housing 1, the output shaft of the cylinder 43 is connected above the piston 42, the cylinder 43 can push the piston 42 to slide up and down in the housing 1, and the cylinder 43 is provided with two and symmetrically arranged along the central axis of the piston 42, which is conducive to the stable movement of the piston 42. The reverse osmosis membrane 41 is symmetrically embedded in the side wall of the housing 1 with the central axis of the housing 1 as the boundary, and the wastewater can filter impurities through the reverse osmosis membrane 41 and discharge to the outside of the housing 1, and a filter screen 77 is installed outside the side of the reverse osmosis membrane 41 close to the blade 52, and the filter screen 77 is arranged parallel to the reverse osmosis membrane 41 and slidably connected to the housing 1, and the filter screen 77 is inserted with activated carbon and PP cotton interlayer inside. When the piston 42 moves downward along the inner wall of the box 1, the waste water is squeezed and converted into circulating water through the filter screen 77 and the reverse osmosis membrane 41, and the circulating water is used for glass cleaning again. Compared with the reverse osmosis reverse osmosis membrane 41 usually arranged horizontally, the reverse osmosis membrane 41 in this scheme is arranged on the side wall to prevent the sediment impurities from directly settling on the surface of the reverse osmosis membrane 41.

搅拌单元包括搅拌辊51、叶片52，搅拌棍51轴向竖直设置且其两端转动连接在箱体的上下内壁，搅拌辊51贯穿活塞42且与活塞42螺纹连接，搅拌辊51上通过花键55套有单向轴承53，活塞42下方同轴固定有限位环57，限位环57水平设置且花键55侧壁转动连接限位环，单向轴承53外转动连接叶片52。当活塞42下移时，由于螺纹连接，搅拌辊51在活塞42的带动下转动，搅拌辊51上的花键55随之转动，并且花键55跟随活塞42上的限位环下移，单向轴承53的内环随花键55转动，单向轴承处于脱离状态，即不会向叶片52传递扭矩，叶片52不转动；当活塞42上移时，搅拌辊51在活塞42带动下反向转动，同时花键55随限位环57向上运动并在限位环57内反向转动，由于单向轴承53处于反转状态，内外圈啮合使得单向轴承53会向叶片52传递扭矩，叶片52与搅拌辊51一同反向转动。The stirring unit includes a stirring roller 51 and blades 52. The stirring roller 51 is axially vertically arranged and its two ends are rotatably connected to the upper and lower inner walls of the box. The stirring roller 51 passes through the piston 42 and is threadedly connected to the piston 42. A one-way bearing 53 is sleeved on the stirring roller 51 through a spline 55. A limiting ring 57 is coaxially fixed below the piston 42. The limiting ring 57 is horizontally arranged and the side wall of the spline 55 is rotatably connected to the limiting ring. The one-way bearing 53 is externally rotatably connected to the blades 52. When the piston 42 moves downward, due to the threaded connection, the stirring roller 51 rotates driven by the piston 42, and the spline 55 on the stirring roller 51 rotates accordingly, and the spline 55 moves downward with the limit ring on the piston 42, and the inner ring of the one-way bearing 53 rotates with the spline 55, and the one-way bearing is in a disengaged state, that is, it will not transmit torque to the blade 52, and the blade 52 will not rotate; when the piston 42 moves upward, the stirring roller 51 rotates in the opposite direction driven by the piston 42, and at the same time, the spline 55 moves upward with the limit ring 57 and rotates in the opposite direction in the limit ring 57. Since the one-way bearing 53 is in a reverse state, the inner and outer rings are engaged, so that the one-way bearing 53 will transmit torque to the blade 52, and the blade 52 and the stirring roller 51 rotate in the opposite direction together.

单向轴承53的外环与叶片52之间竖直穿有销轴54，销轴54为空心结构在水中具有足够浮力，销轴54包括水平段与竖直段，销轴54竖直段的上端限位在叶片52顶部，当销轴54外部有废水时，在浮力作用下，销轴54水平段可插入并限位在单向轴承53外环底部开设的凹槽56内，使得叶片52与搅拌辊51连为一体；当销轴54外部无废水时，失去浮力作用的销轴54水平段脱离凹槽56，叶片与单向轴承外环呈滑动连接状态，搅拌辊51无法带动叶片52转动。利用单向轴承53特性使得叶片52只能在活塞42上移时跟随转动，同时采用浮力控制的销轴54控制叶片52与搅拌辊51的连通，只有位于废水内叶片52才能随搅拌辊51转动，当箱体1内废水排出后，叶片52不转动。A pin shaft 54 is vertically passed through the outer ring of the one-way bearing 53 and the blade 52. The pin shaft 54 is a hollow structure with sufficient buoyancy in water. The pin shaft 54 includes a horizontal section and a vertical section. The upper end of the vertical section of the pin shaft 54 is limited at the top of the blade 52. When there is waste water outside the pin shaft 54, under the action of buoyancy, the horizontal section of the pin shaft 54 can be inserted into and limited in the groove 56 opened at the bottom of the outer ring of the one-way bearing 53, so that the blade 52 and the stirring roller 51 are connected as a whole; when there is no waste water outside the pin shaft 54, the horizontal section of the pin shaft 54 that loses its buoyancy will be separated from the groove 56, the blade and the outer ring of the one-way bearing are in a sliding connection state, and the stirring roller 51 cannot drive the blade 52 to rotate. The characteristics of the one-way bearing 53 are utilized to ensure that the blade 52 can only rotate when the piston 42 moves upward. At the same time, a buoyancy-controlled pin 54 is used to control the connection between the blade 52 and the stirring roller 51. Only the blade 52 located in the wastewater can rotate with the stirring roller 51. When the wastewater in the box 1 is discharged, the blade 52 does not rotate.

叶片52靠近箱体1侧壁的端部内水平开有第一腔体61，第一腔体61内通过第二弹簧62滑动连接有射频芯片63，反渗透膜41下方的箱体1侧壁内对称开有两个出水口3，出水口3内设有射频控制阀门64，当叶片52旋转时，离心作用使得射频芯片63向外运动，射频芯片63感应将射频控制阀门64打开，类似于电子门禁系统。当活塞42向上移动时且叶片52位于水中时，叶片52搅拌箱体1底部，令沉积的泥沙杂质被推动至出水口3排出。A first cavity 61 is horizontally opened in the end of the blade 52 near the side wall of the box body 1. A radio frequency chip 63 is slidably connected in the first cavity 61 through a second spring 62. Two water outlets 3 are symmetrically opened in the side wall of the box body 1 below the reverse osmosis membrane 41. A radio frequency control valve 64 is arranged in the water outlet 3. When the blade 52 rotates, the centrifugal effect causes the radio frequency chip 63 to move outward. The radio frequency chip 63 senses and opens the radio frequency control valve 64, which is similar to an electronic access control system. When the piston 42 moves upward and the blade 52 is in the water, the blade 52 stirs the bottom of the box body 1, so that the deposited mud and sand impurities are pushed to the water outlet 3 for discharge.

通过控制器与箱体1侧壁内设有阀门控制单元，阀门控制单元包括开关71、气囊72、第三弹簧73、压块74，开关71固定在箱体1侧壁，压块74通过第三弹簧73连接箱体1侧壁，且压块74表面平行于开关71，压块74另一侧固定有气囊72，箱体1与活塞42之间的空间设为第二腔体，气囊72与第二腔体连通；箱体1底部中轴处开有第二出水口75，第二出水口75通过控制器电连接开关71，当活塞42向上移动时，气囊72膨胀，推动压块74按压开关71使第二出水口75打开，当活塞42向下移动时，气囊72收缩，压块74离开开关71使第二出水口75关闭。由于废水内含有漂浮杂质，利用箱体1底部中轴处第二出水口75将漂浮杂质与残留废水排出。A valve control unit is provided in the side wall of the box body 1 through the controller. The valve control unit includes a switch 71, an airbag 72, a third spring 73, and a pressing block 74. The switch 71 is fixed on the side wall of the box body 1. The pressing block 74 is connected to the side wall of the box body 1 through the third spring 73, and the surface of the pressing block 74 is parallel to the switch 71. The other side of the pressing block 74 is fixed with an airbag 72. The space between the box body 1 and the piston 42 is set as a second cavity, and the airbag 72 is connected to the second cavity. A second water outlet 75 is opened at the middle axis of the bottom of the box body 1. The second water outlet 75 is electrically connected to the switch 71 through the controller. When the piston 42 moves upward, the airbag 72 expands, pushing the pressing block 74 to press the switch 71 to open the second water outlet 75. When the piston 42 moves downward, the airbag 72 shrinks, and the pressing block 74 leaves the switch 71 to close the second water outlet 75. Since the wastewater contains floating impurities, the second water outlet 75 at the middle axis of the bottom of the box body 1 is used to discharge the floating impurities and residual wastewater.

具体实施过程如下：The specific implementation process is as follows:

控制器令进水口2的进水阀门76打开，玻璃清洁废水进入箱体1内，销轴54卡入单向轴承53凹槽56内，启动气缸43，气缸43推动活塞42向下运动，与活塞42螺纹连接的搅拌辊51带动花键55旋转并与叶片52一同向下运动至箱体1底部。在活塞42挤压下，废水经过滤网77及反渗透膜41过滤，大部分废水被过滤，渗透反渗透膜41下方的箱体1内残留有积压的泥沙杂质及漂浮物，再次启动气缸43使活塞42向上运动，搅拌辊51反向转动并使单向轴承53内外环啮合，单向轴承53、花键55与搅拌辊51同步转动，销轴54在浮力作用下仍卡在单向轴承53的凹槽56内，使得搅拌辊51带动叶片52一同反向转动，射频芯片63向叶片52端部滑动并感应打开射频控制阀门64，此时出水口3打开，转动的叶片52将沉积的泥沙杂质从出水口3排出。The controller opens the water inlet valve 76 of the water inlet 2, and the glass cleaning waste water enters the box body 1. The pin 54 is inserted into the groove 56 of the one-way bearing 53, and the cylinder 43 is started. The cylinder 43 pushes the piston 42 to move downward, and the stirring roller 51 threadedly connected to the piston 42 drives the spline 55 to rotate and move downward to the bottom of the box body 1 together with the blade 52. Under the pressure of the piston 42, the wastewater is filtered through the filter screen 77 and the reverse osmosis membrane 41. Most of the wastewater is filtered, and there are accumulated silt impurities and floating objects in the box 1 below the reverse osmosis membrane 41. The cylinder 43 is started again to move the piston 42 upward, and the stirring roller 51 rotates in the opposite direction to make the inner and outer rings of the one-way bearing 53 mesh. The one-way bearing 53 and the spline 55 rotate synchronously with the stirring roller 51. The pin 54 is still stuck in the groove 56 of the one-way bearing 53 under the action of buoyancy, so that the stirring roller 51 drives the blade 52 to rotate in the opposite direction together, and the RF chip 63 slides toward the end of the blade 52 and senses the opening of the RF control valve 64. At this time, the water outlet 3 is opened, and the rotating blades 52 discharge the deposited silt impurities from the water outlet 3.

随着搅拌辊51跟随活塞42向上运动，叶片52位于水位上方，失去浮力作用的销轴54脱出凹槽56，叶片52与单向轴承53的外环呈脱离状态，叶片52不再转动，同时第二腔体内的空气被挤压至气囊72内，气囊72膨胀推动压板压住开关71，开关71控制第二出水口75打开，箱体1内剩余的漂浮物随废水一同从第二出水口75排出。As the stirring roller 51 moves upward with the piston 42, the blade 52 is located above the water level, the pin shaft 54 which has lost its buoyancy falls out of the groove 56, the blade 52 is separated from the outer ring of the one-way bearing 53, the blade 52 no longer rotates, and at the same time, the air in the second cavity is squeezed into the airbag 72, the airbag 72 expands and pushes the pressure plate to press the switch 71, the switch 71 controls the second water outlet 75 to open, and the remaining floating objects in the box 1 are discharged from the second water outlet 75 together with the waste water.

以上所述的仅是本发明的实施例，方案中公知的具体结构及特性等常识在此未作过多描述。应当指出，对于本领域的技术人员来说，在不脱离本发明结构的前提下，还可以作出若干变形和改进，这些也应该视为本发明的保护范围，这些都不会影响本发明实施的效果和专利的实用性。本申请要求的保护范围应当以其权利要求的内容为准，说明书中的具体实施方式等记载可以用于解释权利要求的内容。The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
