Description

Technical Field

[0002] Municipal engineering generally belongs to the country's infrastructure, which refers to the construction of various public transportation facilities, water supply, drainage, gas, urban flood control, environmental sanitation and lighting in urban construction. It is an indispensable material basis for the survival and development of cities, and a basic condition for improving people's living standards and opening up to the outside world. Sewage treatment is required during the construction of municipal engineering, which mainly includes construction and use of water. Sewage treatment equipment is an industrial equipment that can effectively treat domestic sewage, industrial wastewater, etc. in urban areas, and avoid sewage and pollutants directly flowing into waters. It is of great significance to improve the ecological environment, enhance the quality of cities and promote economic development.

[0003] The existing Chinese patent with announcement number CN218248780U discloses a sewage treatment equipment for municipal engineering, which solves the problem in the prior art that sewage is mostly construction water, which is mixed with a lot of sand, gravel or garbage, which is very easy to cause blockage of sewage equipment pipes. A sewage treatment equipment for municipal engineering includes a box body, the bottom of the box body is fixedly connected to a bottom frame, the inner side of the box body is slidably connected to a filter frame, and the top side of the box body is fixedly connected to a hydraulic cylinder by bolts. The method proposed in the utility model is to filter and carry plastic and large-particle gravel through the filter frame, and then clean them to the second bearing frame through the scraper and brush on the reciprocating screw, and use the bottom frame and its components to filter again, avoiding the problem of sand, gravel or garbage in the traditional method, which is very easy to cause blockage of sewage equipment pipes.

[0004] However, the above-mentioned sewage treatment mechanism has the following disadvantages: the device cleans the filter frame and the second supporting frame by arranging a brush and a scraper, but when filtering the sewage, some impurities will be stuck between the filter screens, and the impurities cannot be cleaned out using only the scraper and the brush, and the filter screen will be worn out after a long time of use, and it needs to be replaced in time, otherwise it will affect the filtering efficiency of the filter screen.

[0005] Therefore, we propose a sewage treatment equipment for municipal engineering to solve this problem.
