Detailed Description

Referring now to the drawings in the specification, in conjunction with specific embodiments, there is illustrated the following: the utility model relates to a self-dredging type sewage sedimentation tank which comprises a tank body 1, a servo motor 2, a threaded rotating shaft 6, a dredging scraper 7, a sewage outlet 11 and a separating part. The inner space of the tank body 1 is divided into a primary filter tank 1-1 and a secondary filter tank 1-2 by arranging a separating part, the separating part comprises a filter plate 4 and a supporting clapboard 5, the filter plate 4 is vertically butted with the supporting clapboard 5 to form a complete separating part, and the primary filter tank 1-1 and the secondary filter tank 1-2 can form a structure with mutually communicated upper parts and mutually separated bottoms through the separating part. The bottom of the inner cavities of the primary filter tank 1-1 and the secondary filter tank 1-2 is provided with a threaded rotating shaft 6, one end of the threaded rotating shaft 6 penetrates out of the side wall of the tank body 1 and is connected with a servo motor 2 through a coupler, the other end of the threaded rotating shaft is connected with the inner side wall of the tank body 1 through a bearing in a rotating mode, a movable dredging scraper 7 is arranged on the threaded rotating shaft 6, a threaded through hole is formed in the dredging scraper 7 and is connected with the threaded rotating shaft 6 in a threaded mode through the threaded through hole, two ends of the dredging scraper 7 are respectively provided with a positioning slide block 10, positioning slide grooves 9 corresponding to the positioning slide blocks 10 are formed in the inner side wall of the tank body 1 and the side wall of the supporting partition plate, and the positioning slide blocks 10 are arranged inside the positioning slide grooves 9 in a sliding mode. And the bottoms of one sides of the primary filtering tank 1-1 and the secondary filtering tank 1-2 are respectively provided with a sewage discharge outlet 11, and the sewage discharge outlet 11 is sealed by a sealing cover plate 3 through bolts.

Furthermore, the bottom end of the dredging scraper 7 is provided with dredging bristles 8.

Further, the bottom surface of the sewage draining exit 11 is provided with an inclined surface 12. The structure of the inclined plane 12 can better discharge the sludge.

The working principle is as follows: the sewage is firstly conveyed into a primary filtering tank 1-1 of a tank body 1 through a pipeline, the sewage is pretreated by a filter plate 4 and then flows into a secondary filtering tank 1-2, after the sewage is settled, the sewage is finally discharged from the secondary filtering tank 1-2 through the pipeline, and the discharged treated water is conveyed into required equipment through the pipeline. When sewage is required to be discharged, the sewage conveying is stopped firstly, the sealing cover plate 3 is opened after water in the primary filter tank 1-1 and the secondary filter tank 1-2 is discharged, then the servo motor 2 is started, the servo motor 2 can drive the threaded rotating shaft 6 to rotate, and as the threaded rotating shaft 6 and the dredging scraper 7 are in threaded connection, when the threaded rotating shaft 6 rotates, the dredging scraper 7 can move along with the threaded rotating shaft, the sludge at the bottom of the tank is scraped, and the cleaned sludge is discharged through the sewage discharge outlet 11 finally.
