Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and more specifically, particularly relates to a sewage treatment filtering device. Background Art

[0002] When treating sewage, it is generally necessary to filter and pre-treat the sewage in order to remove large particles and impurities in the sewage. This usually includes methods such as filtration and adjusting water quality and water volume. Filtration is the removal of larger solid wastes through equipment such as filter boxes to avoid blockage or damage to subsequent process equipment. Existing filter boxes are generally composed of filter screens, water inlets, outlets, and mud discharge pipes.

[0003] The utility model with the existing application number 202022819435.2 discloses a sewage treatment filter device, whose structure includes a filter box, the filter box is provided with a water outlet, a drive motor and a bearing seat, the water outlet is located at the bottom of the filter box, the drive motor is fixedly connected to the right end of the outside of the filter box by screws, the bearing seat is fixedly connected to the middle of the bottom of the filter box by screws, the drive motor is connected to the driving gear through the motor shaft, the bearing seat is connected to the filter cartridge through a fixed shaft, the outside of the fixed shaft is provided with a driven gear, and the inside of the filter cartridge is provided with a limit plate. The utility model realizes that the filter cartridge is rotated during the sewage filtration process, speeds up the drainage speed of the filter cartridge, improves the efficiency of sewage treatment, and reduces the labor intensity of operators when cleaning the filter device, saving time when cleaning the filter device.
