Sewage filtering device convenient for cleaning filter screen

Abstract

The invention discloses a sewage filtering device convenient for cleaning a filter screen. The sewage filtering device comprises a bottom plate, wherein the upper surface of the bottom plate is provided with a sliding chute, and a first pulley and a second pulley are slidably connected with the interior of the sliding chute; the top ends of the first pulley and the second pulley are fixedly connected with the lower surface of a support plate, and the left side of the first pulley is fixedly connected with one end of a first elastic device. According to the sewage filtering device convenient for cleaning the filter screen, through the matching of a first traction rope, a fourth pulley, a first connection plate, a second elastic device, a second connection plate, a second traction rope, a fifth pulley, a second electric push rod and a second fixing plate, the second electric push rod is shortened to cause the counterclockwise rotation and tilting of a box body; at this time, a filter screen body can be washed by using clean water, and then the filter screen body is cleaned by a hairbrush by people, so that solid pollutants on the filter screen are discharged out of the box body, thusmaking the operations by people more convenient.

Description
