Embodiment Construction

[0023] like figure 1 As shown, the present invention includes a base assembly 1, an air channel body 2 installed in the base assembly 1, a disc seat 6 installed on the base assembly 1, and the lower part of the base assembly 1 is connected to the aeration tank There are open openings, or open passages all around, to ensure that the water in the aeration tank is mixed with the air in the base assembly. The base assembly 1, the air duct body 2 and the disc seat 6 are connected as an integral structure as a basis. The inside of the base assembly 1 is a stator channel connected with the outside world to ensure the mixing of water and air; the mixed water and air mixture radiates in a wave-shaped curve under the action of the rotor, and is sent to the surrounding water body. A sealing cover 3 is fixed on the disc seat 6, and it is a sealed connection between the sealing cover 3 and the disc seat 6. A reduction motor 5 is installed in the sealing cover 3, and the reduction motor 5 ...

Abstract

The invention relates to a submersible high-efficiency energy-saving mixing aeration device combined with mixing self suction and blast aeration. The device comprises a base assembly, an air duct body and a disc seat, wherein the air duct body and the disc seat are arranged in the base assembly; a seal outer housing is fixed on the disc seat; a speed reducing motor is arranged in the seal outer housing, and is fixed on the disc seat; an output shaft of the speed reducing motor is connected with a rotating shaft of an impeller; a conical impeller is fixed on the rotating shaft of the impeller; a mechanical seal is arranged between the output shaft of the speed reducing motor and the disc seat; the base assembly is provided with an inlet pipe communicated with the air duct body; and the air duct body is provided with an air outlet. The submersible high-efficiency energy-saving mixing aeration device has the advantages of high oxygen transfer efficiency, energy conservation, consumption reduction, non blockage, stable operation, quick and convenient installation, empty omission of an aeration tank, free motion and lifting of equipment and easy maintenance.

Description

technical field [0001] The invention relates to an aeration device for treating waste water, in particular to a submersible high-efficiency energy-saving stirring aeration device which combines stirring self-priming and blowing aeration. Background technique [0002] Energy conservation and emission reduction is one of the basic national policies of my country's economic and social development. With the in-depth implementation of this basic national policy, my country's industrial sewage and urban sewage have been rapidly treated, the discharge of water pollutants (COD) has decreased year by year, and the circular economy has further developed. With the strengthening of water environment protection, the aeration device used in the biochemical aerobic unit of wastewater treatment is changing with each passing day and flourishing. At present, in wastewater treatment, the main aeration devices commonly used are as follows. [0003] 1. High-power inverted umbrella surface aera...
