Abstract

The invention relates to an unpowered automatic backwashing filtering device which comprises a hydraulic screen, a screen mesh is fixedly connected to one side of the hydraulic screen, the unpowered automatic backwashing filtering device further comprises a water storage tank located in the hydraulic screen and rotationally connected with the hydraulic screen, the top end of the water storage tank is open, and the water storage tank is of an eccentric structure; and a power assisting structure for pushing liquid to impact the screen is arranged above the water storage tank. The method has the effects of reducing energy waste and saving resources.

Description

technical field [0001] The present application relates to the field of water treatment equipment, in particular to an unpowered automatic backwashing filter device. Background technique [0002] Hydraulic screen is a special equipment in sewage treatment machinery as a sewage interception equipment. Hydraulic screen is a kind of equipment used for solid-liquid separation. Under the condition of low suspension concentration, it can effectively reduce the concentration of suspended solids in water, reduce the processing load of subsequent processes, and protect pumps, pipes and instruments. The principle is to use the interception effect of the sieve surface to make the filtered water flow out from the gap of the sieve plate, and at the same time, the solid matter is pushed to the lower end of the sieve plate under the action of hydraulic force, so as to achieve the purpose of separation. [0003] In the process of using the hydraulic screen for a long time, it needs to be cl...
