Problems solved by technology

Traditional stirring machines are divided into vertical shaft folding paddle type and horizontal (submersible) type. Since the installation method and the shape of the paddle determine its stirring form, it is not ideal in terms of energy consumption or stirring effect. Not only will it bring unnecessary increase to the operating cost of the sewage plant, but it will also directly affect the final process treatment effect. How to improve the mixing effect and aeration efficiency while minimizing the cost is a problem that needs to be solved at present

Abstract

The invention discloses an impeller for a stirrer. The impeller is a hyperboloid impeller body; a shaft hole connected with a rotating shaft of the stirrer is formed in the middle of the hyperboloid impeller body; the hyperboloid impeller body is provided with a plurality of arc-shaped aeration channels from top to bottom; and the arc-shaped aeration channels comprise front aeration channels and rear aeration channels, the front aeration channels are inner channels in the hyperboloid impeller body, the rear aeration channels are grooves formed in the surface of the hyperboloid impeller body, and hollow stirring blades cover the grooves. The impeller has the advantages that liquid can do tangential motion along the circumferential direction of the impeller through transition of the hyperboloid structure under the action of gravitational acceleration, circulating water flow is formed from top to bottom under the reflection effect of the tank wall, meanwhile, natural air suction type aeration is conducted through the arc-shaped aeration channels from top to bottom, aeration equipment does not need to be additionally arranged, the stirring aeration effect is improved, and meanwhile thecost is relatively reduced.

Description

technical field [0001] The invention relates to an impeller used for a mixer and belongs to the technical field of sewage treatment. Background technique [0002] In municipal, chemical papermaking and other water treatment processes, water mixing is one of the key processes. Traditional stirring machines are divided into vertical shaft folding paddle type and horizontal (submersible) type. Since the installation method and the shape of the paddle determine its stirring form, it is not ideal in terms of energy consumption or stirring effect. Not only will it bring unnecessary increase to the operating cost of the sewage plant, but it will also directly affect the final process treatment effect. How to improve the mixing effect and aeration efficiency while minimizing the cost is a problem that needs to be solved at present. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide...
