Technical Field

[0001] The utility model relates to the technical field of sewage treatment devices, in particular to a sewage treatment device for municipal engineering. Background Technique

[0002] The sewage treatment device for municipal engineering is an industrial device specifically used for treating urban domestic sewage, industrial wastewater and other water bodies. The treated water can be converted into a water source that can be directly injected into the natural environment, which helps to maintain the sustainable utilization of water resources. The sewage treatment device for municipal engineering plays an important role in improving the urban water environment, protecting water resources and promoting sustainable development.

[0003] When treating sewage in the field of municipal engineering, it is generally necessary to collect sewage and concentrate it through sewage pipes for subsequent treatment. During the collection process, it is necessary to conduct preliminary treatment on the sewage. The treated sewage is discharged into the sedimentation tank for sedimentation operations. However, when conducting preliminary treatment on the sewage, it is usually necessary to use equipment such as a grille slag remover to remove large floating objects and solid particles in the sewage. In this way, multiple devices need to be used in cooperation, which not only occupies a large area, but also requires connection through pipes between multiple devices, which will increase the probability of pipeline blockage. Therefore, a sewage treatment device for municipal engineering is needed to solve the above problems. Summary of the Utility Model

A splicing plate is fixedly connected to the bottom surface of the top plate. The splicing plate is slidably connected with the U-shaped frame. One end of the U-shaped frame is fixedly connected with a baffle. A motor is fixedly connected to one side of the baffle. The output end of the motor is fixedly connected with a spiral auger. The splicing plate and the U-shaped frame are both slidably connected with the spiral auger.
