Description

Technical Field

[0001] The utility model relates to the field of housing and municipal administration, in particular to a multi-layer drainage filter for housing and municipal administration. Background Art

[0002] Housing and municipal services collectively refer to housing construction and municipal infrastructure projects. Housing construction encompasses various types of civil and industrial buildings and their supporting facilities, such as foundations, main structures, and interior decoration. Municipal infrastructure, on the other hand, primarily encompasses urban water supply, drainage, gas, heating, roads, bridges, tunnels, public transportation, sanitation, lighting, and landscaping. Together, these two components constitute a vital component of urban construction and development, providing a comfortable and convenient living environment for urban residents.

[0003] In the prior art, a Chinese utility model patent with publication number "CN221618752U" and patent name "A multi-layer drainage filter for housing and municipal use" discloses a filter for housing and municipal use. The patent records "after the discharged sewage is preliminarily filtered through a coarse filter, the remaining impurities in the sewage are alternately crushed by cutting vertical holes and cutting horizontal holes, so that the volume of the impurities is reduced so that they pass through the fine filter and are discharged together with the sewage. A small amount of impurities are still intercepted by the fine filter after being crushed, so that most of the impurities are crushed and discharged together with the sewage, and a small amount of impurities are respectively blocked on the coarse filter and the fine filter. The blocked impurities will be reduced, and the frequency of regular cleaning of the coarse filter and the fine filter will also be reduced, thereby avoiding the blockage of the coarse filter and the fine filter that affects drainage" and other technical solutions;

Moreover, after long-term use, the coarse filter and the fine filter become clogged due to the influence of impurities, and it is necessary to manually disassemble and clean the coarse filter and the fine filter, and remove the filtered impurities. The operation is cumbersome and increases the labor intensity of the staff, thereby causing inconvenience in cleaning the coarse filter and the fine filter and the impurities.

[0031] It should be noted that the present invention is a multi-layer drainage filter for housing and municipal use. When sewage enters the filter box 1 through the water inlet 4 on the left side of the filter box 1, the first motor 16 will drive the output end to drive the first rotating rod 15 to rotate in the first sealed bearing 8 installed in the first mounting hole 7.
