[0034] Example: Figure 1-Figure 5 , Figure 7-Figure 8As shown, a motor 102, a radiator 103, a reflux valve 104, an oil tank 105, and a filter barrel 106 are provided on the housing 101. A filter cartridge 108 is fixedly connected to the filter barrel 106. A driving component 2, a cleaning component 3, and a debris removal component 4 are provided on the filter barrel 108. The end of the filter barrel 106 away from the driving component 2 is communicated with the reflux valve 104, and the end of the filter barrel 106 close to the driving component 2 is communicated with the oil tank 105. The driving component 2 is used to drive the cleaning component 3 and the debris removal component 4. The cleaning component 3 is used to clean impurities on the filter barrel 108, and the debris removal component 4 is used to discharge the impurities cleaned by the cleaning component 3. The driving component 2 includes a cleaning motor 201, which is fixedly connected to the filter barrel 108. A floating turntable 202 is slidably connected to the cleaning motor 201. The floating turntable 202 is connected to the cleaning motor 201. A plurality of telescopic rods 205 are fixedly connected to the disk 202, and the telescopic rods 205 are fixedly connected to the fixed turntable 305, and the fixed turntable 305 is driven to rotate by the rotation of the cleaning motor 201; the floating turntable 202 is rotatably connected to the worm 206, and the worm 206 is fixedly connected to the fixed shaft 303; the floating turntable 202 is rotatably connected to the incomplete gear 207, and the incomplete gear 207 cooperates with the worm 206; the incomplete gear 207 is fixedly connected to the adjusting cam 209, and the adjusting cam 209 is rotatably connected to the floating turntable 202; the fixed turntable 305 is rotatably connected to the roller 208, and the roller 208 cooperates with the adjusting cam 209; the floating turntable 202 is fixedly connected to the ring gear 204, and a synchronous ring 203 is fixedly connected to both sides of the ring gear 204. The floating turntable 202 is driven to rotate by the cleaning motor 201, and the floating turntable 202 causes the ring gear 204 to rotate, and at the same time, the fixed turntable 305 is rotated through multiple telescopic rods 205; since the worm 206 is stationary, when the floating turntable 202 and the fixed turntable 305 rotate, the incomplete gear 207 will also rotate around the worm 206, and due to the meshing of the incomplete gear 207 with the worm 206, the incomplete gear 207 will rotate, and the incomplete gear 207 causes the adjusting cam 209 to rotate, and since the roller 208 abuts against the adjusting cam 209, when the adjusting cam 209 rotates, the floating turntable 202 will rise longitudinally, and the telescopic rod 205 will retract and return to its original position, and when the cleaning motor 201 rotates in the opposite direction, the incomplete gear 207 drives the adjusting cam 209 to rotate in the opposite direction, the floating turntable 202 descends longitudinally, and the telescopic rod 205 extends.

[0035] like Figure 7-Figure 10As shown, the cleaning component 3 includes a fixed turntable 305, which is rotatably connected to the filter cartridge 108, and a dispersion rack 304 is fixedly connected to the fixed turntable 305. The dispersion rack 304 is in a cone barrel shape and is used to disperse the settled impurities to the surroundings. The dispersion rack 304 is fixedly connected to a cooling rod 301, and the cooling rod 301 is connected to the radiator 103. The cooling rod 301 is spiral, and a thread groove I 311 is provided on the cooling rod 301. The filter cartridge 108 is fixedly connected to a bracket 109, and the bracket 109 is fixedly connected to a fixed shaft 303, and a thread groove II 312 is provided on the fixed shaft 303. A cleaning rod 302 is movably connected to the fixed shaft 303, and the cleaning rod 302 cooperates with the thread groove II 312. The cleaning rod 302 is rotatably connected to a cleaning sleeve 309, which cooperates with a thread groove I 311, and a cleaning strip 310 is provided on the cleaning sleeve 309; the fixed shaft 303 is fixedly connected to a fixed cam disk 306, which is provided with a cam groove, the fixed shaft 303 is rotatably connected to a fixed turntable 305, and the fixed turntable 305 has a plurality of movable frames 308 in a circumferentially equidistant array, the movable frame 308 is rotatably connected to the fixed turntable 305, the movable frame 308 is rotatably connected to the fixed turntable 305, the movable frame 308 cooperates with the cam groove, the movable frame 308 is rotatably connected to a push plate 307, and a torsion spring is provided between the push plate 307 and the movable frame 308; the thread groove II 312 is a circle, and the pitch of the thread groove II 312 is greater than the pitch of the cooling rod 301.The radiator 103 allows the coolant in the cooling rod 301 to circulate continuously to ensure the cooling effect. In the initial state, the dispersion rack 304 is rotated by the rotation of the fixed turntable 305, and the cooling rod 301 is rotated when the dispersion rack 304 rotates. Since the cleaning rod 302 is meshed with the thread groove II 312 and the pitch of the thread groove II 312 is greater than the pitch of the cooling rod 301, the cleaning rod 302 will rise and rotate. At the same time, since the cooling rod 301 passes through the cleaning sleeve 309, the cleaning sleeve 309 will also rotate, so that the cleaning sleeve 309 drives all the cleaning strips 310 to rotate, and the cleaning strips 310 will start to clean the inner wall of the filter cartridge 108. Since the cleaning rod 302 rises and rotates at the same time, the cleaning strips 310 can clean the inner wall of the filter cartridge 108 in all directions. The rotation of the cooling rod 301 can stir the oil in the filter cartridge 108 and cool it evenly; then the cleaning motor 201 reverses to drive the fixed turntable 305 to start reversing, at which time the cleaning rod 302 descends and reverses, and the cleaning bar 310 rotates in the opposite direction to clean the inner wall of the filter cartridge 108 until it is completely reset; on the other hand, the rotation of the fixed turntable 305 causes the movable frame 308 to rotate synchronously, and since the movable frame 308 slides on the cam groove on the fixed cam plate 306, the movable frame 308 will produce reciprocating rotation, that is, when the movable frame 308 moves to near the impurity temporary storage groove 404, the movable frame 308 will reach the maximum swing amplitude, at which time the movable frame 308 causes the push plate 307 to push the impurities into the impurity temporary storage groove 404, and when the fixed turntable 305 rotates in the opposite direction, the push plate 307 still does the same.

[0036] like Figure 6 , Fig.11 , Fig.12As shown, the impurity removal component 4 includes an impurity temporary storage groove 404, which is fixedly connected to the filter cartridge 108, the impurity temporary storage groove 404 is communicated with the filter cartridge 108, the impurity temporary storage groove 404 is fixedly connected to the impurity removal cylinder 403, the impurity temporary storage groove 404 is rotatably connected to the impurity removal shaft 401, the impurity removal shaft 401 is fixedly connected to the spiral blade 402, the spiral blade 402 is in contact with the inner wall of the impurity removal cylinder 403; a through hole is provided on the spiral blade 402, the impurity removal shaft 401 is fixedly connected to the gear 405, the gear 405 is meshed with the gear ring 204, and the gear 405 cooperates with the two synchronizer rings 203. The gear 405 is driven to rotate by the gear ring 204 so that the impurity removal shaft 401 drives the spiral blade 402 to rotate. At the same time, when the floating turntable 202 is displaced longitudinally, the two synchronous rings 203 will drive the gear 405 to move synchronously. When the cleaning motor 201 rotates forward, the impurity removal shaft 401 will also rise. At this time, the spiral blade 402 transports the impurities upward, and the oil is separated from the impurities through the through holes on the spiral blade 402, that is, the spiral blade 402 will only discharge the impurities into the collection box 107; when the cleaning motor 201 rotates reversely, the impurity removal shaft 401 begins to descend, and at the same time, the oil passes through the through holes on the spiral blade 402 in the reverse direction. At this time, the oil can clear some of the through holes blocked by impurities.

[0037] Working principle: When the equipment is running, the oil flows back from the reflux valve 104 to the filter barrel 106 through the pipeline. The oil is first in the filter cartridge 108. Due to the start of the cleaning motor 201, the cooling rod 301 will rotate to cool the oil to prevent the oil temperature from being too high. At the same time, due to the rotation of the cooling rod 301, the cleaning bar 310 also starts to clean the inner wall of the filter cartridge 108 in all directions to prevent impurities from clogging the filter holes on the filter cartridge 108 and ensure the filtering effect; after the impurities are precipitated, they are dispersed to the surroundings by the dispersion rack 304, and then due to the action of the push plate 307, the impurities will be pushed into the impurity temporary storage tank 404, and the synchronous ring 203 drives the impurity discharge shaft 401 to rise, and the gear ring 204 drives the impurity discharge shaft 401 to rotate, so that the floating turntable 202 transports the impurities in the impurity temporary storage tank 404 upward, and then they are collected by the collection box 107. At the same time, due to The through holes on the spiral blade 402 allow oil to pass through, so the oil will not be transported out; when the cleaning rod 302 moves to the top, the cleaning motor 201 starts to reverse, and at this time the cleaning rod 302 starts to descend and rotate in the opposite direction, and the cleaning bar 310 also rotates in the opposite direction to clean the inner wall of the filter cartridge 108, and the impurity discharge shaft 401 starts to descend and rotate in the opposite direction. At this time, the oil can clear the through holes on the spiral blade 402 to prevent impurities from clogging the through holes on the spiral blade 402, causing the oil to be transported to the collection box 107. When the cleaning rod 302 moves to the lowest point, the cleaning motor 201 starts to rotate forward again, and the cycle continues, so that the impurities in the filter cartridge 108 can be discharged continuously, and the motor 102 pumps the oil in the oil tank 105 out for use, without the need for personnel to disassemble and clean, and the oil can be evenly cooled at the same time.

[0038] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
