During the production of cutting fluid, it is necessary to filter it to remove impurities.

[0003] A filtration device for cutting fluid production disclosed in CN221692958U, after the cutting fluid production is completed, the cutting fluid is introduced into the filter cylinder, and the cutting fluid is filtered through the first screen plate and the second screen plate in stages before being discharged from the filter cylinder, thus achieving filtration. This helps to reduce impurities in the produced cutting fluid, and the filter screen plates can be disassembled and installed by removing and installing the sealing block, which is convenient for cleaning or replacing the filter screen plates.

[0004] However, this cutting fluid production filtration device has the following drawbacks: the filter plates need to be removed periodically for maintenance and cleaning during use. During this time, the device cannot continue to filter the cutting fluid, resulting in production interruption and affecting production efficiency. Utility Model Content

Through the arrangement of the branch pipes 2 and the two filter chambers 3, when the filter assembly 8 on one side needs to be cleaned and maintained, the inlet valve 11 and outlet valve 12 on the maintenance side are closed, so that the cutting fluid is filtered from the other filter chamber 3.

[0028] Positioning blocks 4 are fixedly installed on both sides of the outer surface of the filter chamber 3. A positioning mechanism 5 is slidably installed on one side of the positioning block 4. By setting the positioning mechanism 5, the positioning pin 501 is pulled outward to insert the plug block 6 into the positioning block 4. At this time, the filter assembly 8 is inserted into the filter chamber 3. When the positioning pin 501 is released, the reaction force of the spring 502 inserts the positioning pin 501 into the limiting hole of the plug block 6, which achieves the effect of quick installation and disassembly of the filter assembly 8 and facilitates cleaning.

[0029] An insertion block 6 is inserted into the interior of the positioning block 4. A cover plate 7 is fixedly installed on one side of the insertion block 6. A filter assembly 8 is fixedly installed on the bottom surface of the cover plate 7. Through the filter assembly 8, the corrugated neodymium magnet filter plate 801 adsorbs ferromagnetic metal debris in the cutting fluid. The corrugated microporous filter plate 802 and the corrugated activated carbon plate 803 further filter out small impurities. The multi-stage filtration has a good purification effect. The corrugated surface can increase the contact area with the cutting fluid, resulting in high filtration efficiency. A manifold 9 is installed through one side of the filter chamber 3. An output pipe 10 is installed through one end of the manifold 9.

[0030] The positioning mechanism 5 includes a positioning pin 501 and a spring 502.

[0032] A limiting hole is provided on one side of the surface of the plug block 6, and the limiting hole is adapted to the positioning pin 501.

[0033] The limiting hole serves to fix the positioning pin 501.

[0034] The filter assembly 8 includes a corrugated neodymium magnet filter plate 801, a corrugated microporous filter plate 802, and a corrugated activated carbon plate 803. The corrugated neodymium magnet filter plate 801 is fixedly disposed on one side of the bottom surface of the cover plate 7, the corrugated microporous filter plate 802 is fixedly disposed in the middle of the bottom surface of the cover plate 7, and the corrugated activated carbon plate 803 is fixedly disposed on the other side of the bottom surface of the cover plate 7.

[0035] The filter assembly 8 serves to perform multi-stage filtration of the cutting fluid.

[0036] An inlet valve 11 is fixedly installed on the surface of the diverter pipe 2, and an outlet valve 12 is fixedly installed on the surface of the manifold pipe 9.

[0037] The inlet valve 11 controls the opening and closing of the diversion pipe 2, and the outlet valve 12 controls the opening and closing of the manifold 9.

[0038] A sealing gasket 13 is fixedly installed on the top surface of the filter chamber 3. The sealing gasket 13 is made of rubber.

Release the positioning pin 501. The reaction force of the spring 502 will insert the positioning pin 501 into the limiting hole of the plug block 6, and the filter assembly 8 can be quickly installed and removed.

[0044] The second step: the corrugated neodymium magnet filter plate 801 adsorbs ferromagnetic metal debris in the cutting fluid, and the corrugated microporous filter plate 802 and the corrugated activated carbon plate 803 further filter out the tiny impurities. The multi-stage filtration has a good purification effect, and the corrugated surface can increase the contact area with the cutting fluid, resulting in high filtration efficiency.

[0045] Third step: When the filter assembly 8 on the side that needs to be cleaned and maintained is needed, close the inlet valve 11 and outlet valve 12 on the maintenance side so that the cutting fluid is filtered from the other filter chamber 3. The two sets of filter chambers 3 can be switched to ensure normal filtration of cutting fluid in real time without stopping the machine for cleaning and maintenance, thus avoiding production interruption.
