A submersible aerator with stirring device

Abstract

The invention provides an aerator provided with a stirring device, and is used for solving the problem of blockage of a water inlet hole of a general submerged aerator. By improving the structure of the aerator, the problem of blockage at the water inlet of the aerator is solved, the dissolved oxygen of sewage can be increased effectively, and the aeration range of the aerator is expanded. Multiple types of structural designs are adopted in a stirrer, and a hinge type stirring device design or an anchor type stirring device design is generally adopted; by adopting a hinge type stirring device, garbage at the water inlet can be removed effectively, sewage is driven to flow axially, a semi-blocked water inlet hole can be flushed, the aeration of the aerator is enhanced effectively, the dissolved oxygen is increased, and the power consumption is low; by adopting the design of the anchor type stirring device, garbage around the water inlet is removed more effectively during rotating work of the anchor type stirring device.

Description

technical field [0001] The invention designs a submersible aerator, especially a submersible aerator with a stirring device. Background technique [0002] Aeration is a very important process in sewage biochemical treatment. The submersible aerator is driven by a submersible motor to rotate the impeller at high speed, and the impeller generates strong centrifugal force. Under the action of centrifugal force, a negative pressure zone is formed around the impeller, thereby generating self-suction A large amount of fresh air in the atmosphere is continuously inhaled through the suction pipe, and at the same time, the impeller sucks the sewage into the suction hood. In the suction hood, the sewage and the inhaled air collide with each other to form a large number of ultra-fine bubbles and spray them around through the diversion groove. , the jetted gas-liquid mixed flow produces the effect of agitation and convection. However, the water diversion device of the current aerator w...
