[0023] Install the first filter screen 14 and the second filter screen 16 inside the filter barrel 1. The filter holes opened on the first filter screen 14 are denser than those opened on the second filter screen 16. After the industrial wastewater enters the inside of the filter barrel 1 through the water inlet 2, it first contacts the second filter screen 16. The second filter screen 16 can remove large particle impurities in the wastewater. Subsequently, it passes through the first filter screen 14. The first filter screen 14 is used to further remove the dissolved salts and trace harmful substances in the wastewater, realizing the gradual refinement treatment of the industrial wastewater, improving the filtration efficiency and the water quality purification effect. After the industrial wastewater filtration is completed, some impurities will remain on the filter screen. The motor 10 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the connecting frame 12 and the stainless steel brush 13 to rotate. The stainless steel brush 13 is close to the inner wall of the filter screen. Through rotation, it can further clean the impurities remaining on the filter screen, so as to increase the filtration effect of the industrial wastewater. A buffer box 9 is added between the filter barrel 1 and the motor 10. The buffer box 9 can effectively absorb the vibration generated during the operation of the motor 10, thereby improving the stability during the filtration process and the filtration efficiency.

[0024] Further, the outer surface of the first sealing plate 5 is threadedly connected through a first bolt 6, and the first sealing plate 5 is threadedly connected to the filter barrel 1.
