Sewage filtering device capable of facilitating clearing sludge

Abstract

The invention discloses a sewage filtering device capable of facilitating clearing sludge. The sewage filtering device comprises a shell; the shell is internally provided with a filter cartridge; filter holes are formed in the lower surface of the filter cartridge; the lower surface of the filter cartridge is fixedly connected with a first rotating shaft; the outer surface of the first rotating shaft is connected with a bearing in a clamping way; and a first bearing is connected to the lower surface of the inner wall of the shell in a clamping way. According to the sewage filtering device capable of facilitating clearing sludge, the filter cartridge rotates under the matching of a first gear and a second gear, so that sludge residues at the side of the filter cartridge are cleared by a theleft side of a scraping plate; and the sludge residues on the lower surface of the inner wall of the filter cartridge are cleared by the lower surface of the scraping plate, but it is not needed thatthe sludge residues on the inner wall of the filter cartridge are cleared by a worker by using a manual method, so that the time and physical power of the worker are saved, meanwhile, the phenomenonthat hands and clothes of the worker are polluted by the sludge residues is also avoided, convenience is brought for the work of the worker, and the sewage filtering device is beneficial for the workof the worker.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage filter device for conveniently cleaning sludge. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or for reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and it is also increasingly entering the daily life of ordinary people. [0003] Many times there is a lot of sludge in the sewage. In the process of sewage treatment, the sludge in the sewage must be filtered out first. When using the filter cartridge to filter the sludge, after the worker takes out the sludge in the filter cartridge , There are often a lot of sludge residues stuck on the inner wall of the filter cartridge. In many cases, worker...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a sewage filter device for conveniently cleaning sludge, which solves the problem of first filtering out the sludge in the sewage in the process of sewage treatment, and then using the filter cartridge to filter the sludge. When filtering, after the workers take out the sludge in the filter cartridge, there will often be a lot of sludge residues on the inner wall of the filter cartridge. In many cases, workers need to use manual methods to clean the sludge residues on the inner wall of the filter cartridge, thereby The time and physical strength of the workers are wasted, and the sludge residue can easily dirty the hands and clothes of the workers, which brings trouble to the work of the workers and is not conducive to the work of the workers.
