Abstract

The invention discloses an air flotation machine for removing suspended matters in industrial sewage. The machine comprises a water inlet pipe, a stirrer, an air inlet pipe, a mixing tank, an air floatation cavity and a water outlet pipe, the water inlet pipe and the water outlet pipe are communicated with the air floatation cavity; the air inlet pipe and the mixing tank are arranged in the air floatation cavity; the stirrer is matched with the mixing tank, the air inlet pipe is provided with a main pipe body, auxiliary pipe bodies, a balance wheel, a sealing clamping piece, a connecting portand a clamping block. More than two auxiliary pipe bodies are distributed on the main pipe body; the auxiliary pipe body is hinged to the surface of the main pipe body through a sealing clamp, a plurality of auxiliary pipe bodies extend from the main pipe body; the auxiliary pipe body is matched with the balance wheel and the sealing clamping piece, the balance wheel swings slowly, the sealing clamping piece is matched with swing compression of the balance wheel, the balance wheel is sealed in a normal working chamber of the balance wheel, meanwhile, gas generated in the auxiliary pipe body can comprehensively act in sewage under the condition that the auxiliary pipe body does not arouse large liquid stirring, and the gas distribution area is enlarged.

Description

technical field [0001] The invention relates to the technical field of industrial purification, in particular to an air flotation machine for removing suspended matter in industrial sewage. Background technique [0002] The air flotation machine is a machine that uses small air bubbles or tiny air bubbles to make the impurities in the medium float out of the water surface. The air flotation device can be used for some fine particles with a specific gravity close to water in the water body that are difficult to sink or float due to their own weight. In terms of water supply and drainage, the water quality of pretreatment, except for some raw water with more sand and sewage with heavy mechanical impurities, is mostly light suspended particles. Gas is introduced into the sewage in the floating machine to make the air bubbles adhere to the flocs, and the flocs float up with the air bubbles, so as to realize rapid solid-liquid separation; [0003] The gas generated by inflating ...
