During the filtering process, the motor 7 and the transmission shaft 8 can cooperate to drive the multiple groups of stirring plates 10 to rotate, and the rotating stirring plates 10 continuously stir the white oil to accelerate the filtering of the white oil by the first filter screen 9, and the scraper 22 elastically arranged at the bottom of the stirring plate 10 can continuously scrape and clean the upper surface of the first filter screen 9 to prevent debris from accumulating on the surface of the first filter screen 9 and affecting the filtering efficiency of the first filter screen 9 for the white oil;

[0094] At the same time, the elastically arranged impact block 23 is constantly in contact with the cushion block 14 and is lifted up by the cushion block 14. When the impact block 23 is staggered with the cushion block 14, under the action of the third elastic member 26, the impact block 23 impacts the surface of the first filter screen 9, thereby accelerating the filtering of the white oil by the first filter screen 9. At the same time, when the stirring plate 10 rotates inside the filter tank 1, due to inertia, the white oil and debris will continue to accumulate inside the stirring plate 10, and then through the cooperation of the third filter screen 18, the debris will be left inside the stirring plate 10. When the impact block 23 is regularly lifted up under the action of the cushion block 14, The first airbag 29 is continuously squeezed, and the gas inside the first airbag 29 is discharged to the inside of the second airbag 35 through the first exhaust pipe 31. The second airbag 35 expands and pushes the push plate 32 to move. The push plate 32 squeezes the white oil and debris accumulated inside the stirring plate 10. The white oil is discharged through the third filter 18, while the debris is left in the stirring plate 10. When the push plate 32 moves under the expansion of the second airbag 35, it squeezes the white oil and the filtered debris inside the stirring plate 10. During the squeezing, the white oil is squeezed out through the cooperation of the third filter 18 on the second filter 17, while the debris continues to be left. When the elastically arranged third baffle plate 40 contacts the surface of the storage box 19 inside the stirring plate 10, the sundries accumulated in front of the snap-on plate 44 are enclosed, and when the push plate 32 continues to move toward the storage box 19, it squeezes the top plate 58, and the top plate 58, with the cooperation of the second through hole 55, pulls the sealing plate 52 to move, so that the snap-on plate 44 is connected to the interior of the sundries storage chamber 50. At this time, when the push plate 32 continues to move toward the storage box 19, the top block 59 squeezes the squeezing plate 49, and the squeezing plate 49 squeezes the fourth airbag 48, and the gas inside the fourth airbag 48 is discharged to the interior of the third airbag 43, and the third airbag 43 is filled with gas. The airbag 43 expands, pushing the debris on one side of the snap-on plate 44 into the debris storage chamber 50. When the push plate 32 is away from the storage box 19, the push plate 32 no longer squeezes the top plate 58. At this time, under the action of the eighth elastic member 54, the elastically arranged sealing plate 52 pops out to seal the debris storage chamber 50 to prevent the leakage of debris. The bottom of the debris storage chamber 50 is arranged to be a filter net, which facilitates the snap-on plate 44 to push the white oil inside the debris storage chamber 50 to be discharged. When it is necessary to clean the debris, the storage box 19 can be taken out from the inside of the stirring plate 10 through the cooperation of the observation window 5 and the second baffle 16.

[0095] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
