Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of MLCC (multi-layer ceramic capacitor) production equipment, in particular to an MLCC slurry tank cleaning system. Background Art
[0002] The slurry preparation of MLCC (multilayer ceramic capacitor) adopts barium titanate, adhesive, anhydrous ethanol, toluene and other chemical additives, which are put into the slurry tank for mixing and dispersion. The slurry tank has a volume of 100L and forms a double slurry tank grinding system with the sand mill host, that is, a batch mode grinding system (such as Figure 1 As shown), the return port of the grinding host 3 is respectively connected to the return port of the A dosing tank 1 and the return port of the B dosing tank 2, and a feed pump 4 is provided on the pipeline connected between the grinding host 3 and the A dosing tank 1 and the B dosing tank 2; the discharge port of the A dosing tank 1 is connected to the first discharge branch pipe 8, and the discharge port of the B dosing tank 2 is connected to the second discharge branch pipe 9, and the confluence of the first discharge branch pipe 8 and the second discharge branch pipe 9 is connected to the feed port of the grinding host 3 through the discharge main pipe 10; the slurry can be alternately ground between the A dosing tank 1 and the B dosing tank 2 until the product is qualified.
[0003] However, when the input material accounts for 70% of the volume of the batching tank, the system runs and the slurry from batching tank A 1 is sent to batching tank B 2 through the pipeline after passing through the grinding host. When the slurry level in batching tank A 1 decreases to the same height as the stirring and dispersing slurry, the high-speed rotation of the stirring and dispersing blades will cause the slurry to splash onto the top cover and part of the tank wall. Due to the sticky slurry, after continuously adding 50 batches of slurry, the cover and part of the tank wall will be stuck with a 30mm thick, already dried slurry mixture. Continuing the operation will cause the semi-dried mixture to fall back into the batching tank, blocking the pipeline from the slurry outlet of the batching tank, causing the entire system to malfunction, stop production, and cause quality problems. Therefore, it is necessary to regularly shut down the system to disassemble and clean the pipeline of the grinding system, which is troublesome to disassemble and assemble, and is not conducive to the smooth progress of the project. Utility Model Content
[0004] The purpose of the utility model is to provide an MLCC slurry tank cleaning system, which can solve the problem that the dry mixture generated by the feeding and stirring sputtering of the double slurry tanks causes the pipelines and feed pumps of the entire grinding system to be blocked, resulting in equipment failure and production suspension, high cleaning costs after the failure, and the generation of hazardous waste that pollutes the environment.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0029] In this embodiment, in order to facilitate the communication between the grinding main unit 3, the A dosing tank 1 and the B dosing tank 2, the MLCC slurry tank cleaning system of the present invention also includes a return material main pipe 22, a first return material branch pipe 23 and a second return material branch pipe 24.

[0030] It should be noted that if Figure 1 As shown, when the existing grinding system is working normally, the first solenoid valve 6 and the fourth solenoid valve 12 are opened, and the second solenoid valve 7 and the third solenoid valve 11 are closed. The slurry in the B material tank 2 enters the grinding main machine 3 through the second discharge branch pipe 9 and the discharge main pipe 10 for grinding, and under the action of the feed pump 4, enters the A material tank 1 through the return main pipe 22 and the first return branch pipe 23; when it is detected that there is no slurry in the B material tank 2, the second solenoid valve 7 and the third solenoid valve 11 are opened, and the first solenoid valve 6 and the fourth solenoid valve 12 are closed, so that the slurry in the A material tank 1 enters the grinding main machine 3 through the first discharge branch pipe 8 and the discharge main pipe 10 for grinding, and under the action of the feed pump 4, enters the B material tank 2 through the return main pipe 22 and the second return branch pipe 24, thereby realizing the alternating grinding of the slurry between the A material tank 1 and the B material tank 2 until the product is qualified.
[0031] According to the MLCC slurry tank cleaning system of the utility model, Figure 2As shown, a pressure pump 5, a cleaning main pipe 13, a first high-pressure cleaning nozzle 16, a second high-pressure cleaning nozzle 17, a first cleaning branch pipe 18, a second cleaning branch pipe 19, a fifth solenoid valve 14, a sixth solenoid valve 15, a seventh solenoid valve 20 and an eighth solenoid valve 21 are added to the existing grinding system. When working, the fifth solenoid valve 14 is normally open. When it is necessary to clean the A feed tank 1, the third solenoid valve 11, the sixth solenoid valve 15 and the seventh solenoid valve 20 are opened, and the first solenoid valve 6, the second solenoid valve 7, the fourth solenoid valve 12, the fifth solenoid valve 14 and the eighth solenoid valve 21 are closed. Under the action of the pressure pump 5, the slurry in the A feed tank 1 is sprayed out from the first high-pressure cleaning nozzle 16 after passing through the first discharge branch pipe 8, the discharge main pipe 10, the cleaning main pipe 13 and the first cleaning branch pipe 18; then, the second solenoid valve 7, the third solenoid valve 11 and the fifth solenoid valve 14 are opened, and the first solenoid valve 6, the fourth solenoid valve 12, the fifth solenoid valve 14 and the eighth solenoid valve 21 are closed. The solenoid valve 12, the sixth solenoid valve 15, the seventh solenoid valve 20 and the eighth solenoid valve 21 allow the slurry in the A dosing tank 1 to enter the B dosing tank 2 through the original grinding path; when the B dosing tank 2 needs to be cleaned, the fourth solenoid valve 12, the sixth solenoid valve 15 and the eighth solenoid valve 21 are opened, and the first solenoid valve 6, the second solenoid valve 7, the third solenoid valve 11, the fifth solenoid valve 14 and the seventh solenoid valve 20 are closed. Under the action of the booster pump 5, the slurry in the B dosing tank 2 is sprayed out from the second high-pressure cleaning nozzle 17 after passing through the second discharge branch pipe 9, the discharge main pipe 10, the cleaning main pipe 13 and the second cleaning branch pipe 19; then, the first solenoid valve 6, the fourth solenoid valve 12 and the fifth solenoid valve 14 are opened, and the second solenoid valve 7, the third solenoid valve 11, the sixth solenoid valve 15, the seventh solenoid valve 20 and the eighth solenoid valve 21 are closed, so that the slurry in the B dosing tank 2 enters the A dosing tank 1 through the original grinding path. It can be seen that the present invention is connected to the discharge pipe 10 of the grinding system with a pressure pump 5, and the discharge pipe 10 on the outlet side of the pressure pump 5 is bypassed and connected to a cleaning pipe 13, and the cleaning pipe 13 is connected to the first cleaning branch 18 and the second cleaning branch 19 respectively. The first cleaning branch 18 is connected to the first high-pressure cleaning nozzle 16 installed on the top of the A batching tank 1, and the second cleaning branch 19 is connected to the second high-pressure cleaning nozzle 17 installed on the top of the B batching tank 2. Therefore, the slurry of the original grinding system can be used to clean the A batching tank 1 and the B batching tank 2, so that the undried mixture is diluted into the solvent, and a small amount of mixture can be continued to be used as a formula solvent, without generating any mixture and solvent waste, saving production costs and protecting the environment, and avoiding the blockage of the pipeline and feed pump 4 in the entire grinding system, resulting in equipment failure and production suspension, high cleaning costs after the failure, and the generation of hazardous waste to pollute the environment. In addition, during the cleaning process, it can also reduce production downtime, thereby ensuring the continuity of production.
