Cavitation air flotation machine with high decontamination efficiency

Abstract

The invention relates to the field of sewage treatment equipment, and discloses a cavitation air flotation machine with high decontamination efficiency, which comprises a treatment tank, an aeration pipe is arranged on one side in the treatment tank, a breather pipe is arranged in the middle of the aeration pipe, a rotating shaft is movably sleeved in the middle of the breather pipe, and an impeller is arranged at the bottom of the rotating shaft; a motor set for driving the rotating shaft to rotate is arranged at the top of the treatment tank, a return pipe is communicated with one side of the bottom of the aeration pipe, a water inlet pipe positioned above the impeller is communicated with the side surface of the treatment tank, a water outlet pipe is arranged at the other side of the treatment tank, and a rubber diaphragm positioned on the inner side of the water inlet pipe is arranged in the aeration pipe. According to the cavitation air flotation machine with the high decontamination efficiency, through the structural design of the adjusting pipe at the return pipe and the flow limiting effect of the flow limiting sliding plate extending into the adjusting pipe to the return pipe, treated return sewage is subjected to flow limiting during sewage treatment, and the problem that the treatment efficiency of sewage newly entering the aeration pipe is reduced due to the fact that the amount of return sewage is large is solved.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a vortex concave air flotation machine with high pollution removal efficiency. Background technique [0002] Vortex concave air flotation machine is a kind of sewage treatment equipment with low investment, high efficiency and low treatment cost. It is specially used to remove grease, jelly and suspended solids in industrial and urban sewage, which is beneficial to environmental protection and avoids discharge. In sewage, impurities such as grease, jelly and suspended solids are difficult to remove, causing pollution to the environment. [0003] When carrying out sewage treatment, firstly, the untreated sewage first enters the super filter for pretreatment, and obtains preliminary purification through screening and filtration, and the treated sewage is sent to the aeration area in the treatment tank, and the high-speed rotation of the impeller is used to make the The wa...
