[0002] Oil-based conductive slurry is a slurry that suspends conductive materials in an oil matrix and is usually used for lubrication and conductivity of electronic components. In the production process, in order to ensure the uniformity and quality of the slurry, a micro jet homogenizer is usually used.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0039] The technical solution provided by the utility model is introduced below in conjunction with the accompanying drawings and specific embodiments.

[0040] In response to the problem of liquid leakage at the plunger seal of the existing homogenizer 100 during use, this embodiment provides a liquid inlet channel 110 and a liquid outlet channel 120 on the side wall of the cavity for installing the plunger, and provides a cleaning and material recovery device, which can inject cleaning liquid into the cavity to remove materials attached to the plunger, thereby avoiding wear of the plunger seal, and can collect and recycle the cleaned materials, thereby reducing material waste and protecting the surrounding environment.

[0041] Combination Figures 1 to 3 As shown, the cleaning and material recovery device includes a cleaning tank 1, a recovery tank 2 and a production line batching tank 3. Among them, the cleaning tank 1 has a liquid storage chamber 11, in which a certain amount of cleaning liquid is filled, and the first liquid outlet 112 of the liquid storage chamber 11 is connected to the liquid inlet channel 110; the recovery tank 2 has a recovery chamber 21, the recovery chamber 21 is used to store waste liquid, and has a second liquid inlet 211 and a second liquid outlet 212, the second liquid inlet 211 is connected to the liquid outlet channel 120, and a filter structure 22 is arranged in the recovery chamber 21, the filter structure 22 is located between the second liquid inlet 211 and the second liquid outlet 212, so as to divide the recovery chamber 21 into a material recovery chamber 213 and a cleaning liquid recovery chamber 214, and the second liquid outlet 212 is connected to the material recovery chamber 213; the production line batching tank 3 has a closed chamber 31, and the third liquid inlet 311 of the closed chamber 31 is connected to the second liquid outlet 212.

[0042] When the above-mentioned device is used, the cleaning liquid in the cleaning tank 1 can enter the cavity where the plunger is installed through the first liquid outlet 112 and the liquid inlet channel 110 to clean the plunger and remove the material attached to the plunger. The material and the cleaning liquid are mixed to form waste liquid, and the waste liquid then enters the recovery chamber 21 along the liquid outlet channel 120 and the second liquid inlet 211, and is filtered by the filtering structure 22 in the recovery chamber 21 to screen the cleaning liquid and the material in the waste liquid. The screened cleaning liquid enters the cleaning liquid recovery chamber 214, and the screened material enters the material recovery chamber 213, and can enter the closed chamber 31 through the second liquid outlet 212 and the third liquid inlet 311 for sealed storage.

[0043] Through the above arrangement, not only can the material on the plunger be cleared, reducing the wear of the plunger seal and reducing the frequency of plunger replacement and maintenance, but the material can also be collected, improving material utilization and use quality, and preventing the material from directly entering the waste liquid box, thereby avoiding the situation where the solvent in the waste liquid box evaporates and pollutes the environment.

[0044] Furthermore, the material recovery chamber 213 and the cleaning liquid recovery chamber 214 are distributed up and down. In this embodiment, the material recovery chamber 213 is located above the cleaning liquid recovery chamber 214. After the waste liquid enters the recovery chamber through the second liquid inlet 211, it can continue to fall onto the filter structure 22 in the vertical direction, so that the surface of the filter structure 22 can be completely in contact with the waste liquid. Compared with distributing the material recovery chamber 213 and the cleaning liquid recovery chamber 214 left and right, the above-mentioned setting can effectively increase the contact area between the waste liquid and the filter structure 22 and improve the filtering effect. On the other hand, since the particles of the material are generally larger than the particle size of the cleaning liquid, the purpose of collecting the filtered cleaning liquid and material into the cleaning liquid recovery chamber 214 and the material recovery chamber 213 respectively can be achieved to facilitate subsequent operations.

[0045] Specifically, the filter structure 22 includes a filter screen, which is arranged between the second liquid inlet 211 and the second liquid outlet 212, and can receive the waste liquid transported from the second liquid inlet 211 to the recovery chamber 21, and screen and filter the materials and cleaning liquid in the waste liquid. The cross-sectional shape of the filter screen is arc-shaped, and it is convexly arranged in the direction close to the second liquid inlet 211, so as to effectively increase the surface area of ​​the filter screen, further improve the filtering efficiency and capacity, thereby reducing the clogging of the filter screen, extending the service life of the filter screen, and reducing the number of cleaning times.

[0046] Optionally, a third liquid outlet 215 is also provided on the recovery chamber 21, and both ends of the third liquid outlet 215 are respectively connected to the cleaning liquid recovery chamber 214 and the first liquid inlet 111 of the liquid storage chamber 11, so as to recycle the cleaning liquid collected in the cleaning liquid recovery chamber 214 to the liquid storage chamber 11, thereby recycling the cleaning liquid and saving the cost of using the cleaning liquid.

[0047] It should be noted that, in other embodiments, the filtration structure 22 may also include an activated carbon layer, which is arranged below the filter screen to remove harmful chemicals in the cleaning liquid; a filter membrane may also be arranged below the filter screen, and the filtering accuracy of the filter membrane is higher than that of the filter screen, so that the cleaning liquid can be further filtered to intercept smaller particles in the cleaning liquid, thereby further improving the purity of the cleaning liquid to ensure the cleaning effect of the cleaning liquid on the plunger.

[0048] Furthermore, a stirrer 23 is also provided in the material recovery chamber 213. The stirring paddle on the stirrer 23 can stir the material in the material recovery chamber 213 to prevent the material from agglomerating or gathering in the material recovery chamber 213, thereby avoiding the increase in material concentration and clogging the filter screen, resulting in a deterioration in the filtering effect. It can also reduce the number of times the filter screen needs to be cleaned, reduce the work pressure of the operator, and extend the service life of the filter screen.

[0049] Optionally, the cleaning and material recovery device further includes a liquid level sensor 4, a control module, a first fluid control component and a second fluid control component. The liquid level sensor 4, the first fluid control component and the second fluid control component are all electrically connected to the control module, a liquid level sensor 4 is disposed inside each of the cleaning tank 1 and the recovery tank 2, the first liquid outlet 112 is connected to the liquid inlet channel 110 through the first fluid control component, and the third liquid outlet 215 of the recovery chamber 21 is connected to the first liquid inlet 111 of the liquid storage chamber 11 through the second fluid control component.

[0050] In the above arrangement, the two liquid level sensors 4 can measure the liquid levels of the cleaning tank 1 and the recovery tank 2 respectively. When the liquid level in the cleaning tank 1 is higher than the liquid level in the recovery tank 2, the control module can control the first fluid control component to open, so as to automatically control the cleaning frequency and flow rate of the plunger, and make the liquid level in the cleaning tank 1 drop; when the liquid level in the cleaning tank 1 is lower than the liquid level in the recovery tank 2, the control module can control the second fluid control component to open, so as to automatically circulate the cleaning liquid in the cleaning liquid recovery chamber 21 to the liquid storage chamber 11 under the action of the second fluid control component, so as to keep the liquid levels in the cleaning tank 1 and the recovery tank 2 balanced, and avoid the cleaning liquid in one tank body flowing into the other tank body when the fluid flow rate is different, resulting in the "tank bursting" phenomenon.

[0051] Specifically, in this embodiment, Figure 1 As shown, the control module preferably uses a PLC control module with high stability and reliability. The first fluid control component includes a first connecting pipe 51, a first solenoid valve 52 and a first diaphragm pump 53. The two ends of the first connecting pipe 51 are respectively connected to the first liquid outlet 112 and the liquid inlet channel 110. The first solenoid valve 52 and the first diaphragm pump 53 are both arranged on the first connecting pipe 51 and are electrically connected to the control module to automatically and accurately control the flow and pressure of the cleaning liquid entering the liquid inlet channel 110 by controlling the opening degree of the solenoid valve and the pump pressure of the diaphragm pump, thereby ensuring the cleaning effect of the plunger.

[0052] It should be noted that, in this embodiment, the second fluid control assembly includes a second connecting pipe 61, a second solenoid valve 62 and a second diaphragm pump 63, the two ends of the second connecting pipe 61 are respectively connected to the third liquid outlet 215 and the first liquid inlet 111, and the second solenoid valve 62 and the second diaphragm pump 63 are both arranged on the second connecting pipe 61. Through the above arrangement, the total amount of cleaning liquid entering the liquid storage chamber 11 can also be automatically and accurately controlled, thereby further improving the stability of the liquid level balance in the cleaning tank 1 and the recovery tank 2.

[0053] Preferably, in this embodiment, the number of homogenizers 100 is four, and the four homogenizers 100 are connected in parallel, so that the cleaning and material recovery device can clean the plungers in the four homogenizers 100 and recover the materials at the same time, and can adjust the cleaning frequency, cycle and flow rate of the four homogenizers 100 through the control module, the first fluid control component and the second fluid control component, thereby improving the performance of the cleaning and material recovery device. Of course, the utility model does not limit the number of homogenizers 100, as long as the stable cleaning of the plunger and the stable recovery of the material can be guaranteed, they are all within the protection scope of the utility model.

[0054] Optionally, combined Figure 1 , Figure 3 As shown, the cleaning and material recovery device provided in this embodiment also includes a weighing module 24 and a third fluid control component. The weighing module 24 is electrically connected to the control module, and the weighing module 24 is arranged at the bottom of the recovery tank 2. The weighing module 24 can weigh the actual weight of the recovery tank 2, and the third liquid inlet 311 is connected to the second liquid outlet 212 through the third fluid control component. Through the above arrangement, when the difference between the actual weight of the recovery tank 2 and the set weight exceeds the threshold value, the control module can turn on the third fluid control component, so that under the action of the third fluid control component, the material collected in the material recovery chamber 213 is automatically supplemented into the production line batching tank 3, so as to realize the recycling of the material, thereby further improving the intelligent automation of the device.

[0055] In this embodiment, the third fluid control assembly includes a third connecting pipe 71, a third solenoid valve 72 and a third diaphragm pump 73, the two ends of the third connecting pipe 71 are respectively connected to the third liquid inlet 311 and the second liquid outlet 212, and the third solenoid valve 72 and the third diaphragm pump 73 are both arranged on the third connecting pipe 71. Through the above arrangement, the flow rate and pressure of the material entering the closed chamber 31 can be automatically controlled to ensure safety and stability and prevent the material from leaking due to excessive pressure.

[0056] It should be noted that, in this embodiment, Figure 2 As shown, the cleaning tank 1 is also provided with a new liquid replenisher 12 and a fourth solenoid valve 13. The new liquid replenisher 12 is arranged above the cleaning tank 1 and is connected to the liquid storage chamber 11 through the fourth solenoid valve 13.

[0057] Optionally, the cleaning and material recovery device further comprises a nitrogen sealing assembly, which comprises a first injection nozzle 81, a second injection nozzle 82 and a nitrogen output machine 83, wherein the first injection nozzle 81 is connected to the liquid storage chamber 11, the second injection nozzle 82 is connected to the recovery chamber 21, and the nitrogen output machine 83 is simultaneously connected to the first injection nozzle 81 and the second injection nozzle 82. After the nitrogen output machine 83 is turned on, nitrogen can be injected into the liquid storage chamber 11 and the recovery chamber 21, so that the liquid storage chamber 11 and the recovery chamber 21 are both in a positive pressure state, thereby being able to nitrogen-seal the liquid storage chamber 11 and the recovery chamber 21, ensuring that the recovered material does not absorb water, thereby ensuring the quality of the recovered material.

In this embodiment, the first purge member 84 is connected to the recovery chamber 21 through the fourth fluid control assembly, and the second purge member 85 is connected to the liquid storage chamber 11 through the third liquid outlet 215 and the first liquid inlet 111. In this way, when the first purge member 84 is started, the pressure in the fourth connecting pipe 91 becomes lower than the pressure in the liquid storage chamber 11, and the nitrogen entering the liquid storage chamber 11 can enter the recovery chamber 21 through the first connecting pipe 51, the homogenizer 100 and the bottom wire connecting pipe 91. When the second purge member 85 is started, the pressure in the second connecting pipe 61 becomes lower than the pressure in the recovery chamber 21, and the nitrogen entering the recovery chamber 21 can enter the liquid storage chamber 11 through the second connecting pipe 61. By providing the first purge member 84 and the second purge member 85 , the nitrogen in the recovery chamber 21 and the liquid storage chamber 11 can be evenly dispersed, thereby preventing the cleaning tank 1 and the recovery tank 2 from bursting due to excessive nitrogen concentration, thereby ensuring the safety of the cleaning tank 1 and the recovery tank 2 .

In this way, the cleaning tank 1 and the recovery tank 2 can be placed in a positive pressure state, and the safety of the use of the cleaning tank 1 and the recovery tank 2 can be ensured at any time, avoiding the operating pressure of manual monitoring.
