A method for using a high-efficiency filter cartridge of a sewage treatment device

Abstract

The invention provides an efficient filter cartridge of a sewage treatment device, and belongs to the field of sewage treatment devices. The efficient filter cartridge solves the problem that an existing filter cartridge is low in one-time utilization rate. The efficient filter cartridge of the sewage treatment device comprises a filter cartridge body of which the top and the bottom are provided with a top plate and a bottom plate respectively, a threaded rod of which the two ends are fixed to the top plate and the bottom plate and a baffle with a threaded hole; the baffle is in threaded connection with the threaded rod through the threaded hole, the edges of the baffle are attached to the inner walls of the filter cartridge body in a sealing mode, the top face and the bottom face of the baffle are provided with a plurality of upper baffle bars and lower baffle bars in the radial direction respectively, and the top plate and the bottom plate are provided with an upper water inlet receiving port and a lower water inlet receiving port respectively and further provided with a plurality of obliquely-formed upper water inlet holes and lower water inlet holes which are communicated with the upper water inlet receiving port and the lower water inlet receiving port respectively; water can enter the efficient filter cartridge through the upper water inlet holes, so that water flow impacts the upper baffle bars to enable the baffle to move towards the bottom plate; water also can enter the efficient filter cartridge through the lower water inlet holes, so that the water flow impacts the lower baffle bars to enable the baffle to move towards the top plate. According to the efficient filter cartridge, the one-time utilization rate of the filter cartridge can be increased.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment devices, and relates to a method for using a high-efficiency filter cartridge of a sewage treatment device. Background technique [0002] The existing sewage treatment device uses the filter cartridge to filter, but after the sewage enters the filter cartridge, the dirt will accumulate at the bottom of the filter cartridge, and only the part of the wall near the bottom of the cartridge works, and the utilization rate of the upper wall is low, so that The single utilization rate of the filter cartridge is low, so it is necessary to improve it. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the prior art, and provide a high-efficiency filter cartridge of a sewage treatment device that can improve the single utilization rate of the filter cartridge to improve the overall efficiency. [0004] The purpose of the present inv...
