Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage filtering device with a self-cleaning function. Background Art

[0002] Wastewater treatment is the process of purifying sewage so that it meets the water quality requirements for discharge into a water body or reuse; sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people.

[0003] Filtration is the first step in sewage treatment, and is usually carried out by solid-liquid separation. However, this filtering method has a disadvantage, that is, as the filtration time becomes longer, a large amount of solids will accumulate on the filter screen, affecting the filtration efficiency. Therefore, manual cleaning is required, which is very troublesome. A sewage filtration mechanism impurity cleaning device with application number CN202322441462.4 can drive the filter cylinder to rotate through a driving motor, and the arc scraper cleans the filtrate outside the filter cylinder, thereby achieving the purpose of cleaning. However, there is no relatively fixed relationship between the filter cylinder and the treatment tube. Either friction or gap will occur between the filter cylinder and the treatment tube. Both of these situations will make the filtration effect worse. At the same time, since the filter cylinder is only connected to the drive motor by a cross bar, it will sag under the action of gravity, resulting in the arc scraper and the filter cylinder cannot fully rub, which will lead to incomplete cleaning.
