Sewage treatment aeration device

Abstract

The invention discloses a sewage treatment aeration device. The top end of a device body is fixedly connected with a driving motor; the lower end of the driving motor is rotationally connected with adriving shaft; a bearing at the upper end of the driving shaft is rotationally connected with the device body; the upper part of the driving shaft is fixedly connected with a semi-conical gear respectively; a toothed part of the semi-conical gear is meshed with a first conical gear; the first conical gear is fixedly connected with a lead screw; a bearing at the other end of the lead screw is rotationally connected with the device body; the lead screw is in threaded connection with a sleeving block; the front part and the rear part of the sleeving block are fixedly connected with support rods;the end parts of the support rods are connected with sliding chutes in a sliding way; the sliding chutes are formed in the upper part of a swinging plate. According to the sewage treatment aeration device, the lead screw is used for driving the sleeving block to move leftwards and rightwards in a reciprocating way in order to drive the swinging plate to swing and fully mix gas and liquid inside the device body; the second conical gear drives a driven shaft and a stirring bar under the action of an annular conical rack to revolve and rotate simultaneously, so that a better mixing effect is achieved. The device is reasonable and applicable in structural design, gas and liquid are fully contacted and mixed, the sewage aeration efficiency is increased greatly, and time is saved.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to an aeration device for sewage treatment. Background technique [0002] Aeration refers to increasing the contact area between water and air by inflating water or mechanical stirring, and is an intermediate process of aerobic biological treatment of wastewater. A water treatment method that uses impeller brushes or other tools to vigorously agitate the water surface, constantly exchanging gaseous substances and removing volatile substances in the water with new interfaces and atmospheric contacts, or allowing gases to escape from the water, such as removing the odor of water or carbon dioxide and Harmful gases such as hydrogen sulfide; or dissolve oxygen into water to increase the concentration of dissolved oxygen to achieve the purpose of removing iron and manganese or promoting the degradation of organic matter by aerobic microorganisms. [0003] At present, most of the existing sew...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the existing sewage aeration devices have insufficient gas-liquid mixing, which leads to poor sewage treatment effect, and requires multiple cycles of aeration to decontaminate, which consumes a lot of time and is not efficient.
