Abstract

The invention provides a box-type rotor air breaking air flotation device which comprises a box, an electric motor, a transmission shaft, a bubble generator and a foam collecting hood. One side of the box is provided with a water inlet, the other side of the box is provided with a water outlet, the top of the box is provided with the electric motor, the lower portion of the electric motor is connected with the transmission shaft, the lower portion of the transmission shaft is connected with the bubble generator, the upper portion of the box is provided with the foam collecting hood, and the transmission shaft is a hollow shaft and provided with an air inlet. The box-type rotor air breaking air flotation device has the advantages of being low in energy consumption, significant in treatment effect, compact in structure, small in size and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of water treatment for aquaculture, and relates to an air flotation device, in particular to a box-shaped rotor broken air type air flotation device. Background technique [0002] Since the 21st century, the shortage of water resources has threatened the production and life in many parts of the world. The traditional extensive aquaculture production method not only competes with humans for water resources, but also contains particulate solid waste, dissolved metabolic waste, nutrients, antimicrobial agents and drug residues in the aquaculture wastewater, which will cause pollution to its own water body and the surrounding environment ; Therefore, it is imperative to change the aquaculture model. Recirculating aquaculture is an important way to achieve high-efficiency, green and clean aquatic product production. Industrialized recirculating aquaculture is one of the development directions of the aquaculture ...
