Aeration machine

Abstract

The invention relates to an aeration device for aeration and oxygenation during sewage treatment, in particular to an aeration machine. The aeration machine is provided with an aeration wheel, a column connector, a bracket, a variable-speed motor and a motor and is characterized in that: the aeration wheel is connected with the column connector; the column connector is connected with the variable-speed motor; the variable-speed motor is connected with the motor; the variable-speed motor and the motor are arranged on the bracket; and the bracket is generally fixed at the top end of sewage treatment equipment. When the aeration machine is used, the variable-speed motor and the column connector are driven to rotate after the motor is connected to a power supply, so that the aeration wheel is driven to rotate close to a water surface by the column connector. Aerobic growth is undergone on a sewage upper layer, surface layer water is stirred along with rotating blades, oxygenation is performed by directly stirring in an aerobic region, the surface layer water rotates from bottom to top to form a negative-pressure region, and oxygenation is performed through a bypass channel between blades, so that oxygenation capacity is greatly enhanced. The aeration machine has the advantages of reasonable structure, simple manufacturing, convenience in operating, high working efficiency, good economic benefit and the like.

Description

Technical field: [0001] The invention relates to an aeration device for sewage treatment aeration and oxygenation, in particular to an aerator with good use effect. Background technique: [0002] At present, the aerators used for aeration and oxygenation in the prior art generally adopt two types of aerators: bottom aeration type and middle aeration type. Stirring will cause the water quality in the entire aeration zone to become turbid, making the sewage treatment effect poor, the sewage treatment cost increased, and has the disadvantage that it is not easy to be popularized and used in large quantities. Invention content: [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a surface aeration aerator with simple structure and low processing cost. [0004] The present invention can reach through following measures: [0005] An aeration device is provided with an aeration wheel, a column linker, a brac...
