[0033] The top of the rotating rod 301 extends to the top of the box body 20, the top of the extending end of the rotating rod 301 is fixedly connected with a hand wheel 307 for driving the filter element body 310 to rotate, the bottom of the box body 20 is fixedly connected with a liquid discharge pipe 309, the top of the box body 20 is fixedly connected with a liquid inlet pipe 308, and the liquid discharge pipe 309 and the liquid inlet pipe 308 are both in communication with the box body 20, and the filter element body 310 is provided with two groups.

[0034] In particular, when the filter core needs to be replaced, the hand wheel 307 is rotated to drive the rotating rod 301 to rotate 180 degrees in the box 20, at this time, the new filter core is rotated to the bottom of the liquid inlet pipe 308, and the top of the new filter core is butted by the butt joint mechanism 70. The lubricant enters the new filter core through the butt joint mechanism 70 for filtration. The new filter core is directly rotated to the bottom of the liquid inlet pipe 308 through the rotating rod 301. The filter core can be replaced only by simply rotating the rotating rod 301, the replacement time is greatly shortened, the operation efficiency is improved, and the problem of long time caused by the complex steps such as shutdown and disassembly of the filter device in the traditional filter core replacement is avoided.

[0035] The clamping mechanism 40 comprises guide rods 402 symmetrically and slidingly connected to the side surfaces of the circular ring 306. One end of each guide rod 402 is fixedly connected with an arc-shaped plate 401 for extruding the filter core body 310, and the arc-shaped plate 401 is located inside the circular ring 306. The other end of each guide rod 402 is fixedly connected with a connecting plate 403.

[0036] The clamping mechanism 40 further comprises a U-shaped mounting frame 404 fixedly connected to the outside of the circular ring 306.

The other end of the rotating rod 406 is fixedly connected with a rotating shaft 407.

[0037] The rotating shaft 407 is rotatably connected with a push rod 409 outside the rotating shaft 407. A torsional spring 408 is further sleeved outside the rotating shaft 407. One end of the torsional spring 408 is fixedly connected with the outside of the rotating shaft 407, and the other end of the rotating shaft 407 is fixedly connected with the push rod 409.

[0038] In specific work, after the conversion mechanism 30 switches the filter element, the old filter element is ejected out of the box 20 by the ejection mechanism 50. When the old filter element is ejected, the base 305 and the slide rod 304 move vertically upward along the vertical rod 303, the push rod 409 is in contact with the discharge port 501, the push rod 409 is pushed downward by the discharge port 501, under the blockage of the limiting plate 410, the push rod 409 drives the rotating rod 406 to rotate synchronously, the rotating rod 406 drives the roller 405 to disengage from the side of the connecting plate 403, at this time, the roller 405 releases the extrusion on the connecting plate 403, so that the arc-shaped plate 401 synchronously releases the extrusion on the filter element body 310. When the filter element body 310 is ejected out of the box 20, the old filter element can be pulled out of the circular ring 306, and then a new filter element is installed in the circular ring 306. The rotating rod 406 is pressed downward manually to drive the roller 405 to extrude the side of the connecting plate 403, so as to drive the arc-shaped plate 401 to clamp and fix the new filter element in the circular ring 306. Finally, the newly replaced filter element is lowered into the box 20. When the new filter element is lowered into the box 20, the push rod 409 is pushed by the discharge port 501. Since there is no blockage of the limiting plate 410 at this time, the push rod 409 can be rotated along the rotating shaft 407. When the push rod 409 is completely lowered into the box 20, the push rod 409 is rotated to the side of the limiting plate 410 under the torsion of the torsion spring 408. The old filter element after conversion is replaced again so as to convert the filter element later.

[0039] The ejection mechanism 50 includes a discharge port 501 opened in the top of the box 20, and the vertical projection shape of the discharge port 501 is consistent with that of the base 305. The bottom of the box 20 is also vertically and slidably connected with an L-shaped top rod 503. The vertical section of the top rod 503 is in contact with the bottom of the base 305. The horizontal section of the top rod 503 is fixedly connected with a rack 504, and the top of the rack 504 is fixedly connected with a cover plate 502 for shielding the discharge port 501.

[0040] The ejection mechanism 50 further includes a motor 506 fixedly connected outside the box 20. The output end of the motor 506 is fixedly connected with a gear 505, and the gear 505 is engaged with the rack 504.

[0041] In specific work, after the old filter element is converted, the gear 505 is driven to rotate by the motor 506, the rack 504 is driven to move upward by the gear 505, the top rod 503 is synchronously moved upward when the rack 504 moves upward, the bottom base 305 is moved upward by the top of the top rod 503, at the same time, the cover plate 502 is synchronously moved upward by the rack 504, so that the discharge port 501 is opened, the bottom base 305 clamping the old filter element is moved upward along the vertical rod 303, the old filter element is moved from the discharge port 501 to the top of the box body 20, when moving upward, the clamping mechanism 40 releases the clamping and fixing of the filter element body 310, so that the old filter element can be taken out of the bottom base 305, the ejection mechanism 50 can automatically push the old filter element out after the filter element conversion is completed, the manual operation steps are reduced, the operator does not need to pull or knock the filter element, and the taking out is completed, which is suitable for the production environment of frequently replacing the filter element and reduces the daily maintenance burden.

[0042] The limiting mechanism 60 comprises a mounting cavity 602 formed in the vertical section of the top rod 503, a ball 604 is symmetrically and slidingly connected to the side surface of the mounting cavity 602, and a first spring 603 is fixedly connected between the two balls 604 and located in the mounting cavity 602.

[0043] The limiting mechanism 60 further comprises a fixed block 601 symmetrically and fixedly connected to the bottom of the bottom base 305, a recess 605 is formed on the side of each fixed block 601 close to each other, and each recess 605 is rollingly connected with the ball 604, and the fixed block 601 is symmetrically and fixedly connected to the bottom of each bottom base 305.

[0044] In specific work, after the filter element is rotated by one hundred and eighty degrees through the conversion mechanism 30, the ball 604 reenters the recess 605 in the fixed block 601 under the elastic force of the first spring 603, the conversion mechanism 30 is fixed through the cooperation of the recess 605 and the ball 604, the structure that the ball 604 is embedded in the recess 605 can ensure that the conversion mechanism 30 is accurately locked in the preset position after being rotated in place, the fixed reliable filter element position helps to maintain the stable operation of the filtering system, and problems such as pressure fluctuation and unstable flow caused by loose filter element are avoided.

[0045] The docking mechanism 70 comprises an extension pipe 701 fixedly connected to the bottom of the liquid inlet pipe 308, and the extension pipe 701 is located in the box body 20, a moving cover 703 is slidingly sleeved on the outside of the extension pipe 701, a second spring 702 is also sleeved on the outside of the extension pipe 701, one end of the second spring 702 is fixedly connected with the top of the moving cover 703, the other end of the second spring 702 is fixedly connected with the inner top surface of the box body 20, an inclined surface 704 is formed in the bottom of the moving cover 703, and the bottom of the moving cover 703 and the top opening of the filter element body 310 abut each other.

[0046] Specifically, when the conversion mechanism 30 rotates, the moving cover 703 is pressed upward by the old filter element, so that the moving cover 703 moves upward along the extension pipe 701, and then the new filter element is rotated to below the moving cover 703 after the old filter element is rotated by one hundred and eighty degrees, the top of the new filter element first contacts the inclined surface 704 at the bottom of the moving cover 703, thereby pushing the moving cover 703 upward, and when the new filter element is completely moved to the bottom of the moving cover 703, the moving cover 703 is pushed downward to the top of the new filter element by the second spring 702, and the re-engagement of the moving cover 703 can provide a tight sealing environment, thereby avoiding the leakage of lubricant to the outside of the filter element, so that the lubricant can be fully filtered by the filter element, and at the same time, the automatic docking of the moving cover 703 reduces the need for direct contact with the filter element by manual operation, and reduces the safety risk caused by misoperation.

[0047] Working principle: When the filter element needs to be replaced, the new filter element is switched to the bottom of the liquid inlet pipe 308 by the conversion mechanism 30, and after rotation, the liquid inlet pipe 308 is communicated with the top of the new filter element by the docking mechanism 70, and at the same time, the position of the conversion mechanism 30 is fixed by the limiting mechanism 60, after the old filter element is switched, the old filter element is ejected to the outside of the box body 20 by the ejection mechanism 50, and when the old filter element is ejected, the clamping mechanism 40 releases the clamping and fixing of the old filter element, after the old filter element is taken out, the replaced new filter element is first fixed by the clamping mechanism 40, and then the ejection mechanism 50 is lowered into the box body 20, so as to switch the filter element by the subsequent conversion mechanism 30, and the filtered lubricant is discharged from the liquid outlet pipe 309.
