Abstract

The present invention provides a suction-type inverted-umbrella-shaped surface aerator, and belongs to the technical field of sewage treatment equipment, the suction-type inverted-umbrella-shaped surface aerator includes an impeller, a hollow shaft, a mounting plate, a drive mechanism, a pipe and a pump; the hollow shaft is connected with the mounting plate through a bearing, the mounting plate is mounted on a mounting foundation, the first end of the hollow shaft is connected with the drive mechanism, the second end of the hollow shaft is in transmission connection with a first hollow shaft of the impeller, the pipe passes through the first hollow shaft and the hollow shaft, the first end of the pipe is arranged below the impeller, the second end of the pipe is arranged above the impeller, the pipe is provided with the pump and a solenoid valve, the first end of the pipe is provided with a sewage suction port, and the second end of the pipe is provided with a sewage spout. The suction-type inverted-umbrella-shaped surface aerator is simple in structure, highly practical, adequate and uniform in aeration, and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a suction-type inverted umbrella-type surface aerator. Background technique [0002] In the process of sewage treatment, it is necessary to oxygenate the sewage for the growth and reproduction of beneficial bacteria to achieve the purpose of decomposing the organic matter in the sewage. In the prior art, the surface aerator is often used to oxygenate the sewage, and the surface aeration Under the strong propulsion of the impeller, the water is thrown out from the edge of the impeller in the form of a water curtain, forming a water curtain, engulfing a large amount of air, the water circulates up and down, and the liquid level is constantly updated. A large area of ​​sewage is in contact with the air, and the rotation of the impeller drives the water flow. , forming a negative pressure zone, inhaling air, the oxygen in the air quickly dissolves into the sewage, ...
