Flocculation central driving mud scraper

Abstract

The invention discloses a flocculation central driving mud scraper and relates to water treatment equipment. The flocculation central driving mud scraper comprises a central concrete buttress, a central rotating vertical frame, a transmission device, a mud scraping girder, a working bridge, a sewage inlet pipe, a sludge outlet, a conical flocculoreaction cylinder, a medicament inlet pipe and a blender, wherein the sewage inlet pipe, the sludge outlet and the medicament inlet pipe are arranged at the bottom of a tank; the flocculoreaction cylinder is fixedly connected with the working bridge; the blender is arranged on the central concrete buttress; the blender is positioned above the medicament inlet pipe and the sewage inlet pipe; the inlet of the blender of is connected with the medicament inlet pipe and the sewage inlet pipe; and the water outlet of the blender faces the inner conical surface of the conical flocculoreaction cylinder. The flocculation central driving mud scraper has excellent processing effect, ensures that the quality of water reaches standards before discharge, and greatly improves efficiency compared with the conventional simple sedimentation tank, thereby reducing the design diameter of the sedimentation tank and saving investment cost and land resources.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a center-driven mud scraper. Background technique [0002] The radial flow sedimentation tank generally adopts the method of central water inlet and peripheral water outlet, and is equipped with a traditional peripheral drive mud scraper or a center drive pendant type mud scraper, which has problems such as low treatment efficiency, uneven water distribution, and low operating efficiency of the whole machine. Therefore, recently, a radial flow sedimentation tank with peripheral water inlet and peripheral water outlet has been developed to solve the problem of uneven water distribution. Because the radial flow sedimentation tank with peripheral water inlet and peripheral water outlet has extremely high requirements in construction, it is limited in use. However, most of the large-scale sedimentation tanks currently used in my country use radial-flow sedimentation tanks. Therefore, how to...

Problems solved by technology

[0002] The radial flow sedimentation tank generally adopts the method of center water inlet and peripheral water outlet, and is equipped with traditional peripheral drive mud scraper or center drive pendant type mud scraper, which has problems such as low treatment efficiency, uneven water distribution, and low operating efficiency of the whole machine.

Therefore, recently, a radial flow sedimentation tank with peripheral water inlet and peripheral water outlet has been developed to solve the problem of uneven water distribution. Because the radial flow sedimentation tank with peripheral water inlet and peripheral water outlet has extremely high requirements in construction, it is limited in use. However, most of the large-scale sedimentation tanks currently used in my country use radial flow sedimentation tanks. Therefore, how to improve the sedimentation efficiency of the mud scraper and make the discharge of radial flow sedimentation tanks reach the standard discharge has become a very important issue.
