In order to solve such problems, the specific operation is as follows: when the waste transformer oil needs to be treated, connect the oil inlet 2 to the oil tank, open the oil inlet valve, and the waste transformer oil enters the cylinder 1 through the oil inlet 2, and then enters the filter screen 4. The filter screen 4 has an adsorbent inside, which passes downward through the adsorbent. When the waste transformer oil and the adsorbent in the filter screen 4 are fully mixed, open the oil outlet valve, and the oil flows out through the oil outlet 3 after being filtered by the filter screen 4. The adsorption treatment of the waste transformer oil is completed. When the impurities and filter blockage need to be treated, pull the connecting rod 13 upwards one by one, take the hook 14 out of the through slot 7 and turn it in the opposite direction. The filter screen 4 can be taken out of the cylinder 1 by using the mounting frame 5 for cleaning or replacement.
