Device for preventing suspended matter from floating upwards in pressurization mode

Abstract

The utility model discloses a device for preventing suspended matters from floating upwards in a pressurization mode, which relates to the technical field of sewage treatment and comprises a sewage treatment tank and an anti-floating cover arranged in the sewage treatment tank, a lantern ring is fixedly arranged on the outer wall of the anti-floating cover, vertical plates are fixedly arranged on two sides of the lantern ring through connecting plates, and the connecting plates are fixedly connected with the lantern ring. Spiral collectors are arranged on the sides, close to each other, of the two vertical plates, the ends of output shafts of the spiral collectors are rotationally connected with the vertical plates, through holes matched with the spiral collectors for transmission are formed in the side wall of the anti-floating cover, a pressurizing pipe is arranged at the upper end of the outer wall of the anti-floating cover in a communicating mode, and the pipe wall of the pressurizing pipe is fixedly sleeved with a valve and a pressure gauge; and the pipe orifice of the pressurizing pipe is communicated with a pressurizing pump. According to the utility model, the sewage treatment tank, the anti-floating cover, the spiral collector, the pressurizing pipe and the pressurizing pump are arranged, so that suspended matters are effectively prevented from floating upwards in a pressurizing manner, the sewage treatment effect is improved, meanwhile, the pipeline can be prevented from being blocked in the sewage treatment process, and the sewage treatment efficiency is improved.
