Abstract

The invention provides a chemical sewage filtering device and a clearing method thereof. The chemical sewage filtering device comprises a shell, wherein the upper end of the shell is connected with awater inlet pipe; an annular filtering plate is arranged in the shell; the annular filtering plate divides an inner cavity of the shell into a center cavity and a filtering cavity; the water inlet pipe is communicated with the center cavity; the filtering cavity is positioned around the center cavity and is communicated with the center cavity; a drain pipe communicated with the filtering cavity ismounted on the lower side of the cylindrical surface of the shell; the lower end surface of the shell is communicated with a slagging pipe communicated with the center cavity. The chemical sewage filtering device provided by the invention is convenient for cleaning the filtering plate.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a chemical sewage filter device and a cleaning method thereof. Background technique [0002] In the prior art, chemical wastewater needs to be pretreated first. In the pretreatment process, it is necessary to use a filter to intercept the sediment that is drawn out. After a long time of use, the filter will inevitably be blocked. But not easy to clean. Contents of the invention [0003] The technical problem to be solved by the present invention is that when the chemical sewage is pretreated, the filter screen will inevitably be blocked and it is not easy to clean. [0004] In order to solve the above technical problems, the present invention provides a chemical sewage filtering device, which includes a housing, the upper end of which is connected to a water inlet pipe, and an annular filter plate is arranged inside the housing; the annular filter plate divides the ...
