Anti-blocking device for sewage treatment

Abstract

The invention discloses an anti-blocking device for sewage treatment, which comprises a box body, which sequentially includes a drainage cavity, a treatment cavity and a separation cavity from top to bottom, the drainage cavity is provided with a drainage pipe fitting, and the treatment cavity is provided with a crushing cavity. device and filter device, the crushing device includes a crushing box and two crushing assemblies, the filtering device includes a fixed bottom plate, a filter grid frame and a dredging assembly, the filter grid frame includes a filter grid plate, parallel blocks and a fixed frame, and the dredging assembly includes a backing plate, an installation The frame body, the dredging partition, the hydraulic cylinder and the adjusting frame, and the dredging partition are evenly arranged on the mounting frame body. The invention has strong practicability. The large particle impurities in the sewage are crushed into small particle substances through the crushing device, so as to avoid the blockage of the device caused by the large particle substances. The remaining impurities in the filter are removed, and the filter grid is regularly dredged through the dredging component to ensure the smoothness of the filter holes.

Description

technical field [0001] The invention relates to an anti-blocking device for sewage treatment. Background technique [0002] In the formation and development of cities, rivers, as important resources and environmental carriers, are related to urban survival, restrict urban development, and are important factors that affect urban style and beautify the urban environment. Urban rivers have various ecological functions such as water supply, green space, environmental protection, transportation, and cultural education. It shows irreplaceable significance in the construction of cities and the expansion of urban space development. With the acceleration of urbanization in our country, land development and utilization on both sides of the river have damaged the function of urban rivers, and a large amount of industrial and domestic sewage has been directly discharged into the river without treatment, causing river water pollution, water quality deterioration, and river ecological en...

Problems solved by technology

With the acceleration of urbanization in my country, the development and utilization of land on both sides of the river has damaged the function of urban rivers, and a large amount of industrial and domestic sewage has been directly discharged into the river without treatment, causing river water pollution, water quality deterioration, and river ecological environment damage.

In the treatment of sewage, the sewage contains a large amount of particulate impurities. When the sewage is filtered and treated, the device is often blocked, which seriously affects the treatment rate of the sewage.
