Sewage treatment device for activated alumina production

Abstract

The present application belongs to sewage treatment technical field, and relates to a sewage treatment device for activated alumina production, which comprises a treatment tank, a lifting plate is rotatably connected to the other side of the rotating plate, lifting assemblies are symmetrically arranged in the base, a scraper is fixed to one end of the fixed shaft, an angle adjusting assembly is arranged on one side of the scraper, a stirring assembly is arranged on one side of the fixed plate, a stirring piece is fixed to the bottom end of the stirring assembly, and a feeding cylinder is fixed to the top end of the base. Through the double-layer screw rod transmission of the screw rods on the two sides of the treatment tank and in the moving seat, the bidirectional precise displacement of the scraper in the horizontal and vertical directions is realized, the scraper can be stably sent to any position at the bottom of the tank, the limitation that the traditional stirrer can only disturb the middle and upper water bodies is broken, the bottom stirring blind area is reached, the scraper is in a completely horizontal state at the lowest point, the contact area of the mud scraping surface and the tank bottom is improved compared with the traditional inclined scraper, the high-density aluminum mud particles are forced to be suspended, and are fully mixed with the water body.
