Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments; based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0015] like Figure 1 、 Figure 2 As shown, the milling machine cutting fluid purification device described in the present invention includes a first liquid storage tank 10, a filter box 20, a filter body 30, a second liquid storage tank 40, a gear transmission mechanism 50 and a pipeline system 60. The filter box 20 is located above the second liquid storage tank 40, and a connecting pipe 21 connected to the first liquid storage tank 10 is provided on one side of the lower part of the filter box 20; the filter body 30 is hollow cylindrical and vertically arranged in the filter box 20, and a hollow shaft structure is extended at both ends of the filter body 30 and the hollow shaft passes through the filter box 20. The lower end of the filter body 30 is connected to the second liquid storage tank 40, and the two ends of the filter body 30 are respectively sleeved with a first bearing 31 and a second bearing 32; the gear transmission mechanism 50 includes a motor 51, a driving gear 52 and a driven gear 53. The driving gear 52 is installed at an output end of the motor 51, and the driven gear 53 is horizontally arranged above the first bearing 31. The driven gear 53 is meshed with the driving gear 52. The rotation of the motor 51 drives the filter body 30 to rotate via the gear meshing; The pipeline system 60 includes a first water pump 61, a first pipeline 62 and a second pipeline 63 connecting the first liquid storage tank 10 and the filter box 20. The first pipeline 62 is connected to the internal space at the upper part of the filter box 20; the second pipeline 63 is connected to a flushing conduit 64 arranged at the bottom of the filter box 20, and the flushing conduit 64 is provided with multiple groups of nozzles. The first pipeline 62 and the second pipeline 63 are respectively provided with a first pneumatic stop valve 65 and a second pneumatic stop valve 66 connected in series.

[0016] Among them, a guide slope 22 is provided at the bottom of the filter box 20, and the lower end of the guide slope 22 is connected to the connecting pipe 21. The flushing conduit 64 is located at the higher end of the guide slope 22. The multiple groups of nozzles arranged on the flushing conduit 64 are facing the connecting pipe 21, and the connecting pipe 21 is provided with a third pneumatic stop valve 23 in series.

[0017] Furthermore, the cylindrical outer wall of the filter body 20 is covered with a filter screen, which is arranged in a zigzag fold line. The filter screen can filter particulate matter such as iron filings, and the zigzag fold line form increases the filtering area and filtering efficiency of the filter screen.

[0018] A rotary sealing mechanism 24 is provided between the hollow shaft at the bottom of the filter body 30 and the filter box 20 .

[0019] like Figure 2 A gas cleaning pipeline 25 is provided in the filter body 30. The gas cleaning pipeline 25 includes a Z-shaped air pipe 251 inserted into the filter body 30 and multiple groups of nozzles 252 provided on the Z-shaped air pipe 251. The Z-shaped air pipe 251 is fixed to the filter box 20. After the Z-shaped air pipe 251 is connected to compressed air, air flow is ejected from the nozzle 252.

[0020] Among them, the first liquid storage tank 10 is provided with a liquid inlet 11 on the top and a partition 12 at the bottom. The partition 12 has holes. The iron filings pass through the holes and settle to the bottom of the first liquid storage tank 10, reducing the chance of being sucked in by the first water pump 61.

[0021] A second water pump 41 and a water supply pipeline 42 are provided on one side of the second liquid storage tank 40 .

[0022] By adopting the above technical solution, the cutting fluid containing iron chips enters the first liquid storage tank 10 from the liquid inlet 11, and the strip-shaped and large iron chips initially settle to the lower part of the partition 12; when in use, the first water pump 61 is started and the first pneumatic stop valve 65 is opened, at which time the second pneumatic stop valve 66 and the third pneumatic stop valve 23 are in the closed state; the cutting fluid flows into the filter box 20 through the first pipeline 62, and the iron chips are isolated from the outside of the filter body 30 by the filter screen. The cutting fluid enters the filter body 30 and falls into the second liquid storage tank 40, and is pumped to the workbench through the second water pump 41 and the water supply pipeline 42, thereby realizing the purification and recycling of the cutting fluid. After a period of operation, when the filter 30 has isolated a certain amount of iron chips, the filter 30 is cleaned in the following steps: the third pneumatic stop valve 23 is opened, and the cutting fluid flows from the filter box 20 into the first liquid storage tank 10. The motor 51 is started, and the driving gear 52 drives the driven gear 53 to rotate, driving the filter 30 to rotate together. Under the action of centrifugal force, the iron chips attached to the outside of the filter 30 are thrown off and fall to the bottom of the filter box 20. At the same time, compressed air is introduced into the gas cleaning pipeline 25, and the air flow is sprayed from the nozzle 252 to further clean the filter 30. The first water pump 61 is started, the second pneumatic stop valve 66 is opened, and the first pneumatic stop valve 65 is closed. Liquid is sprayed out of the flushing conduit 64, and the iron chips accumulated in the lower part of the filter box 20 flow back into the first liquid storage tank 10 through the connecting pipe 21. The flushing conduit 64 is located on the side with the higher guide slope 22, which is more convenient for flushing. Most of the iron chips are accumulated below the partition 12 of the first liquid storage tank 10, which effectively avoids clogging of the filter screen and improves the filtration efficiency.
