Description

Technical Field

[0001] The utility model relates to the technical field of sewage filtering grille nets, in particular to a grille net with adjustable hole sizes. Background Art

[0002] Sewage lifting refers to a process or equipment that lifts wastewater or sewage from a low place to a high place for transportation. Specifically, it is mainly used to solve the problem of insufficient sewage treatment facilities in residential and commercial areas in the process of urbanization, as well as the problem that sewage cannot flow naturally in low-lying areas or places where sewage pipes need to be raised.

[0003] The existing prefabricated pump station outlet pipe with integrated crushing grid is equipped with a garbage recycling grid net to intercept incompletely crushed debris to avoid affecting the operation of subsequent sewage treatment. However, the existing grid aperture cannot be adjusted. When the grid aperture is relatively small, impurities with smaller particle sizes in the sewage are also intercepted, and the grid holes will be blocked quickly. The blocked grid will lose its function of intercepting impurities, and impurities in the sewage will overflow into the subsequent sewage with the water flow, affecting the requirements of the subsequent treatment process; when the grid aperture is too large, impurities with smaller particle sizes will not be intercepted, affecting the subsequent sewage treatment process.

[0004] Under some operating conditions, the particle size of impurities in sewage changes periodically. Fixed-aperture grilles cannot adjust the grille aperture in real time according to changes in sewage water quality. If adjustment is required, the grille needs to be replaced, which involves a lot of work and high operating costs.

[0005] At present, no effective solution has been proposed to address the problems in related technologies, such as the grille aperture cannot be adjusted and is prone to clogging, which affects subsequent sewage treatment. Utility Model Content
