Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a multi-stage sewage outlet intercepting and filtering device. Background Technique

[0002] During the sewage discharge process, most sewage contains a large amount of kitchen waste and industrial residues. In order to avoid directly discharging these impurity wastes into the sewage treatment plant, it is necessary to intercept and filter the sewage. Most of the existing intercepting and filtering devices are filter meshes. However, during the long-term interception and filtration of sewage, the surface of the filter mesh is often blocked by kitchen waste and impurities. Especially some larger wastes such as plastic bags may directly adhere to the surface of the filter mesh during the interception and filtration process, affecting the filtration of the filter mesh. In severe cases, it may even cause difficulty in draining the pipeline, resulting in blockage. At this time, it is necessary to clean the filter mesh. However, the existing filter meshes are generally installed inside the pipeline, which makes manual cleaning more troublesome and affects the drainage efficiency of the entire drainage pipeline. Content of the Utility Model

[0003] The purpose of the utility model is to provide a multi-stage sewage outlet intercepting and filtering device to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme:

One side of the sewage discharge box is fixedly connected with a fixed shaft, and a retaining groove is arranged on the other side of the sewage discharge box. One end of a rotating baffle is rotatably connected to the fixed shaft, and the other end of the rotating baffle is fitted with the retaining groove. An inner bracket is arranged on the inner wall of the sewage discharge box, a retaining edge is installed on the inner bracket, and two groups of symmetrically arranged collecting hoppers are fixedly connected to the retaining edge. A first-layer filter mesh, a second-layer filter mesh, a third-layer filter mesh, and a fourth-layer filter mesh are arranged between the collecting hoppers. The first-layer filter mesh, the second-layer filter mesh, the third-layer filter mesh, and the fourth-layer filter mesh are arranged in sequence along the sewage flow direction of the sewage discharge box. The filtering holes in the first-layer filter mesh, the second-layer filter mesh, the third-layer filter mesh, and the fourth-layer filter mesh gradually decrease along the sewage flow direction of the sewage discharge box.
