Sewage filtering method for conveniently cleaning sludge

Abstract

The invention discloses a sewage filtering method for conveniently cleaning sludge. When sludge residues on the inner wall of a filter cartridge need to be cleaned, a control panel controls a second electric drive pusher to be shortened, the second electric drive pusher drives a second pulley to move leftwards, and the second pulley does not upward extrude first extrusion blocks; at the moment, under the action of a tensile force of second springs, the second springs downwards pull a second transverse plate; the second transverse plate drives a second rotating rod to downward move by a secondbearing, a second rotating shaft and a second gear; a motor and a first gear downward move along with the second transverse plate, the second rotating rod downwards moves and is clamped in a second clamping groove, and the condition that the sludge residues on the inner wall of the filter cartridge by a manual method with the help of workers is avoided, so that time and physical strength of the workers are saved; meanwhile, the phenomenon that hands and clothes of the workers are stained by the sludge residues is avoided, further the convenience is brought for work of the workers and the workof the workers is facilitated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage filtering method 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, wor...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a sewage filtration method for cleaning sludge conveniently, which solves the problem that in the process of sewage treatment, the sludge in the sewage should be filtered out first, and then the sludge should be filtered out by using the filter cartridge. 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.
