Sewage treatment filtering device

Abstract

The invention relates to the technical field of sewage treatment, in particular to a sewage treatment filtering device which comprises at least two filtering mechanisms, and each filtering mechanism comprises a filtering pipeline and a filtering plate; the filtering plate is arc-shaped and has flexibility, and comprises a filtering surface with a plurality of sieve pores and triggering lugs which penetrate through the filtering pipeline in the radial direction and protrude out of the upper side and the lower side of the filtering pipeline; and the output end of the deformation driving assembly is in transmission connection with the trigger lug of the filter plate. A deformation driving assembly in the filtering mechanism drives a triggering lug of a filtering plate to enable the filtering plate to generate repeated deflection deformation, so that the filtering plate repeatedly oscillates in sewage flow to wash and wash blockages on the filtering plate, and meanwhile, sewage in a filtering pipeline forms impact water waves towards the filtering plate of the adjacent filtering mechanism. According to the filtering mechanism, the self-cleaning capability of the filtering mechanism can be realized, so that the filtering plate is cleaned more thoroughly, the cleaning effect of the filtering mechanism is improved, and the overall filtering efficiency of sewage is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a filter device for sewage treatment. Background technique [0002] Sewage treatment equipment can effectively treat urban domestic sewage, industrial wastewater, etc., and prevent sewage and pollutants from flowing directly into waters, which is of great significance to improving the ecological environment, improving urban quality and promoting economic development. [0003] Sewage treatment requires the use of filter plates to filter particulate matter, and too much filter residue on the filter plate will affect the overall filtering effect, so it needs to be cleaned regularly. At present, most of the filter plates used in sewage treatment devices on the market do not have the function of self-cleaning, which leads to the need to manually clean the filter plates frequently in order to ensure the filtering effect of the existing filtering devices. On the one hand, the o...
