Rack-and-pinion cooperated aeration treatment device for medical sewage

Abstract

The invention discloses a rack-and-pinion cooperated aeration treatment device for medical sewage. The rack-and-pinion cooperated aeration treatment device comprises a device box, a connecting frame,an aeration box, a rotating motor, a stirring auger and a diagonal filter plate, wherein the lower side of a slide block is symmetrically welded with the connecting frame; the lower side of the connecting frame is fixedly with the aeration tank; the center of a driven gear is provided with a stirring shaft in an interference fit manner; and the lower end of the stirring shaft is fixedly connectedwith the stirring auger. Since the stirring auger clockwise and anticlockwise rotates intermittently, the aeration treatment device provided by the invention has better sewage aeration effect and morethorough aeration compared with common single-direction-stirring aeration. At the same time, the aeration box moves leftward and rightward, so the internal stirring range of the stirring auger is larger; and thus, the occurrence of aeration dead angles in the aeration box is avoided and the effect of aeration is further improved.

Description

technical field [0001] The invention relates to an aeration device, in particular to a rack-and-pinion aeration treatment device for medical sewage. Background technique [0002] Aeration refers to the process of forcibly transferring the oxygen in the air to the liquid, the purpose of which is to obtain sufficient dissolved oxygen. In addition, aeration also has the purpose of preventing the suspended matter in the pool from sinking and strengthening the contact between organic matter in the pool, microorganisms and dissolved oxygen, so as to ensure that the microorganisms in the pool can oxidize and decompose organic matter in sewage under the condition of sufficient dissolved oxygen. [0003] When performing aeration treatment on medical sewage, the effect of aeration is not good by stirring the aeration in one direction. At the same time, there are often cases where the aeration box is not in place or the aeration is dead, which greatly reduces the aeration effect. Simu...

Problems solved by technology

[0003] When performing aeration treatment on medical sewage, the effect of aeration is not good by stirring the aeration in one direction. At the same time, there are often cases where the aeration box is not in place or the aeration is dead, which greatly reduces the aeration effect. At the same time, when the sewage is filtered, the sundries stay in the device box and it is difficult to clean up
