[0037] (3) A recovery device for oil pollution treatment of CNC machine tools, which guides impurities entering the interface upward along the guide tube by rotation, thereby preventing impurities from accumulating at the bottom of the scraper assembly for a long time and causing secondary pollution to the filter plate, avoiding the reuse of filtering resources, saving filtering resources, and improving environmental protection.

[0038] (4) A recovery device for oil pollution treatment of CNC machine tools can timely and effectively guide the exported impurities out through the guide port.

[0087] The other end side of the first upper plate 604 is attached to the cleaning device 403 .

[0088] The working principle of the present invention is as follows:

[0089] Step 1: The middle tube 205 and the tube plate 206 divide the space inside the warehouse tube 201 into two parts, the front half of the space is used for filtering the cooling oil, and the back half of the space is used for cleaning the filter plate 3; the mixed cooling oil is introduced into the front plate space of the warehouse tube 201 through the first conduit 202, filtered through the filter plate 3, and finally the filtered cooling oil is discharged through the second conduit 203; during this period, the panel 601 is driven downward by the contraction cylinder 402, and the pressure plate 603 adapted to the front half of the space of the warehouse tube 201 is pressed downward through the connection of the vertical plate 602, thereby supplying the pressure for the cooling oil to be filtered through the filter plate 3, thereby improving the cooling oil filtering efficiency.

[0090] Step 2: After repeating the pressurized filtering operation several times, the impurities in the cooling oil are basically accumulated above the filter plate 3. The starting motor 102 drives the machine column 103 to rotate, and drives the filter plate 3 to rotate clockwise through the connecting ring 104. In this way, the impurities on the surface of the filter plate 3 will be accumulated around it through its own rotation and the existence of the scraping component, while the filter plate 3 transferred from the rear half of the warehouse tube 201 to the front half is relatively clean, and the impurities accumulated on the filter plate 3 can be exported in time, ensuring that the filter plate 3 always has clean mesh for filtering, so that it is in an efficient working state, and the filtering efficiency of the filter plate 3 is stabilized.

[0091] Step 3: The rotation of the machine column 103 further drives the toothed disc 107 to rotate, and the inner column 212 rotates through the meshing of the tooth group 108 and the middle tube 205, so that the spiral screw plate 214 adapted to the inside of the guide cylinder 210 rotates, so that the impurities entering the interface 211 are guided upward along the guide cylinder 210 through rotation, so as to avoid the long-term accumulation of impurities at the bottom of the scraping component to cause secondary pollution to the filter plate 3, avoid the reuse of filtering resources, save filtering resources, and improve environmental protection.

[0092] Step 4: Through the setting of the recovery mechanism 5, the impurities discharged through the rotation of the screw plate 214 inside the guide cylinder 210 will enter the recovery bin 501 for retention, and the lower wall surface of the recovery bin 501 gradually decreases in height from the middle to both sides, so that the discharged impurities can be further discharged through the guide port 502 in a timely and effective manner. Furthermore, by the upper surface of the inner arc wall of the recovery bin 501 being fitted with the toothed disc 107, impurities can be prevented from overflowing into the main bin mechanism 2, thereby improving the safety of the discharge of impurities.

[0093] Step 5: During the rotation of the filter plate 3, the presence of the scraper assembly can scrape off the impurities accumulated on the surface of the filter plate 3. Therefore, only impurities embedded in the filter holes remain on the filter plate 3 that enters the rear half of the warehouse tube 201. When the filter plate 3 rotates to the rear plate part of the warehouse tube 201, the cleaner 403 will first spray the filter plate 3, and then through the linkage of the upper cleaning assembly and the pressure plate 603, the upper plate column 605 is inserted into the filter holes of the filter plate 3 and then inserted into the scraper 220, so as to dredge the filter holes of the filter plate 3. Finally, the filter plate 3 is wiped by the second upper plate 606 and the second lower plate 221, so as to complete the cleaning of the filter plate 3 and improve the ability of automatic cleaning of the filter plate 3.

[0094] Step 6: Through the setting of the lower cleaning component, the warehouse pipe 201 and the cylinder 402 work alternately, so that when the upper plate column 605 dredges the impurities in the filter holes of the filter plate 3 and is inserted into the scraper 220, the upper cone pipe mouth of the scraper 220 and the upper plate column 605 are adapted and plugged to further scrape the impurities on the outer part of the scraper 220. When the cylinder 402 stops working and the warehouse pipe 201 starts working, the rotation of the machine column 103 will cause the rope ring 105 to rotate with it under the action of friction. In addition, the rope ring 105 is connected to the plate column 218 through the pull rope 106. Therefore, when the machine column 103 rotates, the power is further converted into the first lower plate 217 sliding along the slide groove 208 through the plate column 218. When the first lower plate 217 slides to the right, the cleaning device 403 sprays the filter plate 3 to simultaneously clean the impurities on the outside of the scraper 220, and finally the impurities are all circulated to the rear half of the warehouse pipe 201 and discharged outward through the third duct 204, thereby improving its cleaning ability.

[0095] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
