The invention belongs to the field of flotation machine, particularly a cavitation air flotation machine. In order to solve the problem that the common cavitation air flotation machine can not simultaneously perform precipitation and desilting, the invention provides a novel cavitation air flotation machine which comprises an aerator, an aeration section, a water inlet, support legs, a reflux section, an air flotation tank, a slag scraper, a scum discharge port, a precipitation tank, a baffle, a water outlet, a U-shaped groove, a speed variator, a motor, a silt discharge port and a non-axis screw. All the structures above constitute a deslagging system and a desilting system. The cavitation air flotation machine can discharge light impurities which float up, and the heavy impurities are precipitated and discharged by the non-axis screw, thereby implementing simultaneous and continuous proceeding of the deslagging and desilting.
Description
technical field [0001] The invention relates to the field of air flotation machines, in particular to a vortex concave air flotation machine. technical background [0002] At present, 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. Light suspended particles can be removed by air flotation, while heavier particles need to be removed by sedimentation; the current air flotation machines only have a single air flotation function, or have intermittent sedimentation and sand removal functions, and cannot achieve sand removal. Unification of sand and slag discharge. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide a vortex concave air flotation machine, which has the functions of slag discharge and sand discharge. [0004] The technical scheme that the present invention t...
