背景技术Background technique
真空滤油机是根据水和油的沸点不同原理而设计的，真空滤油机包括初滤器4、真空加热罐﹑油泵18﹑过滤装置﹑冷凝器(即凝汽器)和真空泵17等部分。真空泵17将真空加热罐内的空气从真空加热罐的气相出口抽出形成真空，外界油液在大气压的作用下，经过初滤器4，清除较大的颗粒，然后进入真空加热罐内的加热区。经过加热后的油液通过喷翼飞快旋转将油分离成半雾状，油中的水份急速蒸发成水蒸气，并混合空气连续被真空泵17吸入冷凝器内，进入冷凝器的水蒸气经冷却后再返原成水放出，在真空加热罐内的油液，被排油泵18排入精滤器19通过滤油纸或滤芯将微粒杂质过滤出来，从而完成真空滤油机迅速除去油中杂质、水份、气体的全过程，使洁净的油从出油处排出机外。三级真空首先是为了实现“大抽速”，即效率，快速增加真空度；其二增加真空闪蒸的面积，有效的快速破乳化，除去水分。目前市场上现有的三级真空滤油系统中，采用喷翼或喷头将油分离成半雾状，从而实现将水蒸腾为水蒸气。但因为本来介质就为污油，故喷翼或喷头很容易被污物堵塞，影响过滤效果且发生堵塞后不易清洗；喷头的喷油方向固定，而喷翼的喷射通道较少，二者均不能很好地将油分离为雾状从而实现油水分离；而喷翼或喷头有很多附加零件组成，包括螺栓螺帽，在高速旋转时易有零件掉落，对油体造成二次污染；在冷凝工序中，一般采用两级水冷，冷凝器采用结构简单的列管换热器，为使气流得到较大冷量，设计气相走壳层，冷却水走管程，但如此设置，气流对管程的换热管有累计的冲击作用，长久使用，换热管易破裂损坏，影响换热效果。The vacuum oil purifier is designed according to the different boiling points of water and oil.

The lower fixing piece is symmetrical about the central axis of the lower body; the upper structure includes a cylindrical upper body for matching the lower body, the central axis of the upper body and the central axis of the lower body are coaxial, and the upper body The top of the upper body is provided with a motor that drives the upper body to rotate along the central axis of the upper body, the upper body is provided with four through holes matching the raised structures, and the bottom surface of the upper body is provided with thirty Y-shaped through holes matching the lower fuel injection grooves. The upper oil injection groove is a Y-shaped oil injection groove, and the upper oil injection groove and the lower oil injection groove cooperate to form a Y-shaped oil injection groove that sends the oil from the oil pipe to the atomizer. The first upper fixing member and the second upper fixing member that cooperate with the second lower fixing member, the first upper fixing member and the second upper fixing member are symmetrical about the central axis of the upper body, and the first lower fixing member faces away from the lower The end of the side wall of the body, the end of the second lower fixing piece away from the side wall of the lower body, the end of the first upper fixing piece away from the side wall of the upper body, and the end of the second upper fixing piece away from the side wall of the upper body are all provided. Limiting structure; the upper structure and the lower structure are detachably connected through the through hole and the protruding structure, when the protruding structure is inserted into the through hole, it is detachably connected between the first upper fixing piece and the first lower fixing piece A first spring is arranged, a second spring is detachably arranged between the second upper fixing piece and the second lower fixing piece, and the top of the first spring is provided with a first top hook that can be hooked on the first upper fixing piece , the bottom of the first spring is provided with a first bottom hook that can be hooked on the first lower fixing member, and the top of the second spring is provided with a second top hook that can be hooked on the second upper fixing member, so The bottom of the second spring is provided with a second bottom hook that can be hooked on the second lower fixing member; the bottom end of the Y-shaped lower fuel injection groove is connected to the oil passage, and the two top ends of the Y-shaped lower fuel injection groove extend to the bottom the outer wall of the body , then the Y-shaped lower oil injection groove connects the oil channel and the space in the vacuum tube, that is, the oil injection groove formed by the upper oil injection groove and the lower oil injection groove also connects the oil channel and the space in the vacuum tank. In order to achieve the purpose of sending the oil out of the atomizer, the upper body and the lower body rely on the convex strips to pass through the through holes to form a complete atomizer, and the motor drives the upper body to rotate along the central axis of the upper body, that is, drives the lower body to rotate together, and then The atomizer rotates on the oil inlet pipe, the oil first enters the lower oil injection tank from the oil delivery pipe, and then continues to spread to the upper oil injection tank that matches the lower oil injection tank, and finally fills the entire oil injection tank. The oil injection tank is connected to the oil channel and the The space in the vacuum tank, then the movement trajectory of the oil in the oil injection tank is: the oil is affected by the centrifugal force due to the rotation of the lower body, and enters the bottom end of the Y-shape of the lower oil injection tank and the upper spray from the circular oil channel. The bottom end of the Y shape of the oil tank spreads over the entire fuel injection tank, and finally leaves the atomizer from the two tops of the Y shape of the fuel injection tank. The type of oil injection groove can divide the oil circuit into two, so that the oil can be discharged from one port and then from 2 ports, that is, the oil has a branch when it leaves the atomizer. There are 60 oil injection grooves in total. At the oil outlet, the oil is driven to rotate in the atomizer, and is thrown out through 60 oil outlets, that is, not only because of the increase of the oil outlet, the process of turning the oil into small oil droplets is more thorough, and the atomized oil is more stable. The effect is better, and because the oil circuit is divided into two by the Y-shaped fuel injection tank, it is equivalent to being suddenly decompressed, the oil and water spread more widely at the oil outlet, and the atomization is more thorough and easier. And because of the structural characteristics of the Y-shaped fuel injection groove, when the oil is shunted at the Y-shaped shunt, it will be subjected to the buffer resistance and collision brought by the two tops of the Y-shaped to the oil, causing water vapor and atomization. The oil particles are better separated after being collided, and the collision can make the loose dirt in the oil be scattered without being blocked by the dirt, and the oil will be dispersed into small oil droplets more thoroughly after being collided; The groove is decomposed into the design of the upper fuel injection groove and the lower fuel injection groove. The upper body and the lower body are fixed by the convex strips and the through holes, which are easy to disassemble and clean, and the additional parts such as bolts and nuts are reduced, and the oil body is reduced. Risk of secondary pollution; the angle α between the two top ends of the Y-shaped lower fuel injection groove is 10°, and the angle α between the two tops of the Y-shaped upper fuel injection groove that matches the lower fuel injection groove is 10° , then the angle α between the two top ends of the Y-shape of the fuel injection groove is 10°, and the bifurcation with a smaller angle is adopted to rationally and scientifically utilize the space inside the upper body and the lower body.

②采用两台大抽气速率的罗茨泵与真空泵组成的真空机组对系统进行抽真空，保证能将油液中蒸发出的水蒸气及其它气体快速排出；对真空罐内蒸发出的高温高热水蒸气及其它气体进行冷凝除水、气液分离处理，增强系统的有效输出功率，，大大延长真空泵的使用寿命，于真空泵前设置真空单向阀、波纹补偿器，真空单向阀防止非正常情况下气体倒窜，保护了前序设备，而波纹补偿器起到降低管道变形应力和提高管道使用寿命的作用；②Using a vacuum unit composed of two Roots pumps and vacuum pumps with a large pumping rate to evacuate the system to ensure that the water vapor and other gases evaporated from the oil can be quickly discharged; Water vapor and other gases are condensed and dewatered, gas-liquid separation treatment, enhance the effective output power of the system, greatly prolong the service life of the vacuum pump, set the vacuum check valve and ripple compensator in front of the vacuum pump, and the vacuum check valve prevents abnormal Under the circumstance, the gas backflow protects the pre-sequence equipment, and the corrugated compensator plays the role of reducing the deformation stress of the pipeline and improving the service life of the pipeline;
③上本体、下本体依靠凸条穿过通孔结合为完整的雾化器，电机带动上本体沿上本体中心轴转动，即带动下本体共同转动，进而雾化器于进油管上转动，油从输油管首先进入下喷油槽，然后继续蔓延至配合下喷油槽的上喷油槽，最终填满整个喷油槽，喷油槽连通油路通道与真空罐内的空间，那么在喷油槽内油的运动轨迹为：油因为下本体的转动，受离心力影响，从圆形的油路通道进入下喷油槽Y字型的底端与上喷油槽Y字型的底端，进而蔓延满整个喷油槽，最后从喷油槽Y字型的两顶端离开雾化器，喷油槽Y字型的两顶端成为油路出口，呈Y字型的喷油槽能将油路一分为二，使油从一个端口进而从2个端口出，即油在离开雾化器时产生了分路，三十个喷油槽一共有六十个油路出口，油在雾化器内被带动旋转，并经六十个油路出口甩出，即不仅因为增加了油路出口，使油变为小油珠的过程更加彻底，雾化油的效果更好，而且因为油路在被Y字型的喷油槽一分为二的分流，相当于突然被减压，油、水在油路出口扩散范围更大，雾化更彻底，更容易被分离；③The upper body and the lower body are combined into a complete atomizer by means of the convex strip passing through the through hole. The motor drives the upper body to rotate along the central axis of the upper body, that is, drives the lower body to rotate together, and then the atomizer rotates on the oil inlet pipe, and the oil From the fuel pipe, it first enters the lower fuel injection tank, and then continues to spread to the upper fuel injection tank that matches the lower fuel injection tank, and finally fills the entire fuel injection tank. The fuel injection tank connects the oil channel and the space in the vacuum tank. The movement trajectory of the oil in the tank is: due to the rotation of the lower body, the oil enters the bottom end of the Y shape of the lower fuel injection tank and the bottom end of the Y shape of the upper fuel injection tank from the circular oil channel under the influence of centrifugal force, and then It spreads over the entire fuel injection tank, and finally leaves the atomizer from the two tops of the Y shape of the fuel injection tank. The two tops of the Y shape of the fuel injection tank become the oil outlet. Divided into two, so that the oil comes out from one port and then two ports, that is, when the oil leaves the atomizer, a branch is generated. There are a total of 60 oil outlets in the 30 oil injection grooves, and the oil is in the atomizer. It is driven to rotate, and is thrown out through 60 oil outlet, that is, not only because the oil outlet is increased, the process of turning oil into small oil droplets is more thorough, and the effect of atomizing oil is better, but also because the oil outlet is The Y-shaped fuel injection tank is divided into two parts, which is equivalent to being suddenly decompressed, the oil and water diffuse more widely at the oil outlet, the atomization is more thorough, and it is easier to be separated;
④因为Y字型的喷油槽结构上的特性，油在Y字型的分流处分流时会受到Y字型两顶端对油带来的缓冲阻力与碰撞，使水蒸气与雾化油颗粒受到碰撞后更好分离，而油在被碰撞后分散为小油珠更为彻底，且碰撞能使油中的较为松散的污物被撞散而不被污物堵塞；④Because of the structural characteristics of the Y-shaped fuel injection tank, when the oil is shunted at the Y-shaped shunt, it will be subjected to the buffer resistance and collision of the oil by the two tops of the Y-shaped, so that the water vapor and the atomized oil particles are affected. It is better to separate after collision, and the oil is more thoroughly dispersed into small oil droplets after being collided, and the collision can make the loose dirt in the oil be smashed and not blocked by dirt;
⑤采用将喷油槽分解为上喷油槽与下喷油槽的设计，用凸条配合通孔结合固定上本体、下本体，易拆分、易清洗，且减少了螺栓螺帽等附加零件，降低了油体被二次污染的风险；⑤It adopts the design of decomposing the fuel injection groove into the upper fuel injection groove and the lower fuel injection groove. The upper body and the lower body are fixed by the convex strips and the through holes, which are easy to disassemble and clean, and reduce the additional parts such as bolts and nuts. , reducing the risk of secondary contamination of the oil body;
⑥第一弹簧、第二弹簧对称设置，完全起到拉紧上本体与下本体的作用，使上本体与下本体不会在转动的过程中分开，而因为弹簧的弹性，在需要分离上本体与下本体时，只需取下弹簧即可分离，结构简单、操作简便，保证工作状态下上本体、下本体不会分离即保证了油雾化的效果；⑥The first spring and the second spring are symmetrically arranged, which fully play the role of tightening the upper body and the lower body, so that the upper body and the lower body will not be separated during the rotation process, and because of the elasticity of the spring, the upper body needs to be separated. When it is separated from the lower body, it can be separated only by removing the spring. The structure is simple and the operation is simple. It ensures that the upper body and the lower body will not be separated under the working state, which ensures the effect of oil atomization;
⑦喷油槽Y字型两顶端之间的夹角α为10°，采用较小角度的分叉，合理、科学地利用了上本体与下本体内部的空间。⑦The angle α between the two top ends of the Y-shaped fuel injection tank is 10°, and a smaller angle of bifurcation is adopted to rationally and scientifically utilize the space inside the upper body and the lower body.
