Sewage treatment aeration tank drainage structure with self-cleaning function

Abstract

The invention discloses a sewage treatment aeration tank drainage structure with a self-cleaning function. The drainage structure comprises a drainage structure main body; a top cover is arranged at the top of the inner end of the drainage structure main body; a drainage frame is fixedly connected to the lower end of the top cover; the top cover comprises a protective shell, a filter screen, a bottom plate and a communicating pipe; the protective shell is arranged at the top of the inner end of the top cover; the lower end of the protective shell is fixedly connected with the filter screen; the bottom end of the filter screen is fixedly connected with the bottom plate; the communicating pipe is arranged at the inner end of the center of the bottom plate; and the drainage frame comprises acleaning frame, a water passing pipe, a fixing frame and a sleeve disc, the water passing pipe is arranged at the center of the drainage frame, the sleeve disc is fixedly connected to the top end of the water passing pipe, and the side end of the sleeve disc is fixedly connected with the fixing frame. According to the sewage treatment aeration tank drainage structure with a self-cleaning function,through the arrangement of the drainage frame, the purpose of self-cleaning of the inner end is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a sewage treatment aeration tank drainage structure with self-cleaning. Background technique [0002] The drainage structure of the sewage treatment aeration tank can help the aeration and drainage work of the sewage treatment. Through the setting of the drainage structure of the sewage treatment aeration tank, the rapid drainage operation can be realized, so that the water capacity of the aeration tank can be changed, and the water level of the aeration tank can be adjusted. and through the setting of the drainage structure of the sewage treatment aeration tank, it can meet the purpose of real-time replacement of the inner water body, facilitate the regulation of the aeration tank, and facilitate the full aeration task. However, the drainage of the sewage treatment aeration tank is currently The structure has the following problems, and there is a phenomenon t...
