Description

Technical Field

[0001] This utility model relates to the technical field of solvent filtration equipment, and in particular to a solvent filtration device. Background Technology

[0002] Compared to other solvents, water-based adhesives for MLCCs have a very low evaporation rate, making it difficult for water-based cast films to form a uniform and good surface in a short time.

[0003] In the preparation of water-based adhesives for MLCCs, to ensure the density and purity of the solvent, the solvent needs to be filtered and purified by placing it on the inner wall of a filter. This filter is equipped with a stirring shaft that drives the stirring blades. The stirring shaft is connected to a motor at the top of the filter, allowing the motor to drive the stirring shaft and thus stir the solvent. The rotating stirring blades push and scrape the solvent against the inner wall of the filter screen. Solid particles are then isolated on the inner wall of the filter screen, and the purified solvent is discharged from the filter's output. Currently, conventional filters only have a single stirring blade installed on the outer wall of the stirring shaft. The solvent is filtered from top to bottom by the pushing and scraping of each blade. A single stirring blade cannot achieve comprehensive filtration of the solvent. Therefore, some solvents require multiple layers of stirring blades on the inner wall of the filter to achieve purification. This process requires repeated operations, which is time-consuming and labor-intensive. To address this, a solvent filtration device has been designed. Utility Model Content

A fixing screw is provided at the connection between the can lid 203 and the can body 1. The fixing screw is threaded through the connection between the can lid 203 and the can body 1 to achieve a fixed connection between the can lid 203 and the can body 1. The stirring rod 3 passes through the can lid 203 and is rotatably connected to the motor 101 at the top. The stirring rod 3 drives the connecting plate 301 to rotate. The connecting plate 301 drives the connecting block 303 and the stirring blade 501 to rotate, thereby achieving the filtration of the solvent at the filter screen 102.

[0027] Specifically, the connecting part 2 includes an inlet flange 201 and an outlet flange 202. The inlet flange 201 is located on the outer wall of the tank body 1, and the outlet flange 202 is located on the outer wall of the tank body 1 at the end away from the inlet flange 201.

[0028] It should be noted that the connection part of the inlet flange 201 and the outlet flange 202 is based on the scraper filter of model ZS-525. Before operation, the inlet flange 201 needs to be connected to the solvent output tank and the outlet flange 202 needs to be connected to the solvent discharge pipe. During operation, the solvent will be transported from the inlet flange 201 into the inside of the tank 1 for filtration. After filtration, it will be discharged from the outlet flange 202.

[0029] Specifically, a motor 101 is provided at the top of the can lid 203, and the output end of the motor 101 passes through the middle of the can lid 203 and is fixedly connected to the top of the stirring rod 3.

[0030] It should be noted that the motor 101 is based on the rotating device of the scraper filter with model number ZS-525. The motor 101 is fixed on the top of the tank cover 203. When the motor 101 is started, the motor 101 rotates the stirring rod 3 through the output end.

[0031] Specifically, the top of the multiple connecting discs 301 is provided with multiple connecting grooves 302, and the bottom of the multiple connecting blocks 303 is provided with multiple connecting pins 304, with the outer wall of the multiple connecting pins 304 sleeved with the inner wall of the multiple connecting grooves 302.

[0032] It should be noted that when the operator installs the connecting block 303, the connecting pin 304 at the bottom of the connecting block 303 needs to be fitted into the connecting groove 302 for convenient installation. The top of the connecting plate 301 is surrounded by multiple connecting grooves 302, so that multiple connecting blocks 303 can be installed on the top of the connecting plate 301 at the same time.

[0033] Specifically, multiple sliding blocks 402 are provided on the outer wall of multiple connecting blocks 303 and at one end near the stirring rod 3. The outer wall of the multiple sliding blocks 402 is slidably connected to the inner wall of multiple sliding grooves 401. Multiple locking plates 403 are provided on the outer wall of multiple connecting blocks 303 and at one end near the sliding grooves 401. Multiple fixing bolts 404 are threadedly connected to the top of the multiple locking plates 403.

[0034] It should be noted that before the connecting groove 302 is connected to the connecting pin 304, the sliding block 402 needs to slide along the sliding groove 401. The sliding block 402 will drive the connecting block 303 to slide to the top of the connecting plate 301, so that the connecting groove 302 can quickly connect with the connecting pin 304. At the same time, the connecting block 303 is fixed to the top of the connecting plate 301 under the connection of the sliding block 402 and the connecting pin 304. The locking plates 403 are staggered and fixed to the outer wall of the connecting block 303. When the connecting block 303 is installed, multiple locking plates 403 will be stacked together. At this time, the fixing bolt 404 is threaded through multiple locking plates 403 to achieve the overall fixation of the locking plates 403 and the connecting block 303.

[0035] Specifically, multiple connecting rods 5 are provided on the outer wall of multiple connecting blocks 303 and at one end near the tank body 1. The ends of the multiple connecting rods 5 away from the connecting blocks 303 are fixedly connected to the outer wall of multiple stirring blades 501.

[0036] It should be noted that connecting rods 5 are fixed to the outside of multiple connecting blocks 303, and stirring blades 501 are fixed to one end of the connecting rods 5. The stirring blades 501 and the connecting rods 5 are installed at an angle. When the stirring rods 3 rotate, they will drive the connecting discs 301 to rotate. The connecting discs 301 will then drive the connecting rods 5 to rotate through the connecting blocks 303. At the same time, the connecting rods 5 will drive the stirring blades 501 to rotate on the inner wall of the filter screen 102, thereby achieving the filtration of the solvent.

[0037] Working principle of this utility model:

[0038] The specific operation involves the operator installing multiple connecting blocks 303 on the top of the connecting plate 301. During installation, the sliding block 402 is slid along the inner wall of the sliding groove 401 of the fixed block 4. When the sliding block 402 slides to the bottom of the sliding groove 401, the connecting pin 304 at the bottom of the connecting block 303 will be fitted onto the inner wall of the connecting groove 302. At the same time, the locking plates 403 on the outer wall of the connecting block 303 will stack on top of the connecting plate 301. Finally, the fixing bolt 404 is threaded through the locking plate 403 and the connecting plate 301, thus securing the connecting rod 5 and the stirring blade 501. The operator places the assembled stirring rod 3 and filter screen 102 onto the inner wall of the tank 1, then starts the motor 101. The motor 101 drives the stirring rod 3 to rotate, at which point the solvent is output from the inlet flange 201. The solvent flows from the inlet flange 201 to the inner wall of the tank 1, and is pushed and scraped onto the inner wall of the filter screen 102 by the stirring of the stirring blade 501. With the cooperation of the stirring blade 501 and the filter screen 102, the fixed particles in the solvent are isolated on the inner wall of the filter screen 102 by the pushing and scraping of the stirring blade 501. The filtered solvent is discharged from the outlet flange 202.
