The filtered waste oil can be discharged through the oil outlet pipe 3. After the device has been used for a period of time, when a lot of impurities accumulate on the filter screen, the cover plate 6 is moved upward by the cylinder 8 according to the pre-set extension amount. The cover plate 6 and the filter frame 4 at its bottom can be moved to the top of the filter box 1. During this process, the inner wall of the guide sleeve 12 slides along the guide rod 13, which can guide the movement of the filter frame 4 and the cover plate 6. The collection box 17 can be moved by the positioning rod 19 installed at one end of the collection box 17 and the positioning rod 19 can be inserted into the positioning sleeve 14. The collection box 17 is then fixed by the self-locking property of the universal wheel 20, so that one end of the guide box 18 is located at the bottom of the filter frame 4. The sealing baffle 11 is moved by the electric push rod 10, which facilitates the scraping of the impurities accumulated on the filter screen 5 in the direction of the guide box 18, so that the impurities fall into the collection box 17 for collection and treatment. The operation is relatively simple.
