Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to a filtering structure for municipal drainage. Background Art

[0002] Municipal administration refers to various aspects of a city's administrative management. It also encompasses market trade and urban management. This includes industry, commerce, transportation, public security, culture and education, the environment, sanitation, and infrastructure. Municipal life involves water consumption and, consequently, large amounts of domestic wastewater. Domestic wastewater often contains large amounts of contaminants and impurities, so municipal drainage pipes are generally equipped with filtering and anti-clogging mechanisms.

[0003] Utility model patent CN211646634U discloses a filtering and anti-blocking structure for municipal drainage, comprising a base, a water inlet pipe fixedly connected to the top of the base, a valve body fixedly connected to the top of the water inlet pipe, the valve body passing through the water inlet pipe, an anti-blocking structure housing fixedly connected to one end of the water inlet pipe, a motor protective housing fixedly connected to the top of the anti-blocking structure housing, and a motor support rod fixedly connected to the inner side wall of the motor protective housing. This filtering and anti-blocking structure for municipal drainage achieves the purpose of having a good anti-blocking effect for the filtering and anti-blocking structure for municipal drainage, thereby solving the problem of poor anti-blocking effect of conventional filtering and anti-blocking structures for municipal drainage.

[0004] However, the anti-blocking structure uses a brush to brush off impurities on the filter net, but since the water inside the pipe is in a flowing state, the impurities will still stick to the filter net along the direction of the water flow. At the same time, when there are too many impurities inside, the motor drives the brush to play an anti-blocking role, but it will make the water in the pipe more turbid, thereby affecting the subsequent filtering effect.
