Description

technical field [0001] The invention relates to a filtering device, which is used for filtering suspended solids and residues in liquid and further purifying the liquid. Background technique [0002] In the process of sewage treatment, some fine particles cannot be degraded and accumulate for a long time to form suspended solids and sediments. If they are discharged into the water area, it will destroy the environment on which aquatic organisms live and pollute the water body. Contents of the invention [0003] In order to solve the above problems, the present invention provides a filtering device, which has the advantages of simple structure, automatic recoil and so on. [0004] The present invention adopts the following technical solutions: a filter device, which includes a recoil filter tank and a fixed cylinder, an air inlet pipe is arranged at the upper end of the recoil filter tank, the fixed cylinder is welded inside the recoil filter tank, and the fixed cylinder A...
