Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a high-efficiency air-floating sewage treatment device. Background Art

[0002] Air flotation is an efficient sewage treatment technology, mainly used to remove suspended solids, grease, colloids and other hydrophobic or water-like tiny particles that are difficult to naturally settle in wastewater. At present, the residues obtained by the equipment using air flotation method are all left in the box, which is not convenient to clean. For example, the Chinese patent with authorization announcement number CN 204999645U discloses a sewage treatment air flotation dosing device. After completion, there will be residues in the air flotation tank, which is very troublesome for the staff to clean up. For this reason, we propose an efficient air flotation sewage treatment equipment. Utility Model Content

[0006] A stirring mechanism for stirring the interior of the box body 1 is installed on the box cover 14 ; an electric air pump 11 is also installed on the top of the box cover 14 , and the outlet of the electric air pump 11 is connected to an air duct 7 , and the air duct 7 is connected to an air inlet port 18 .

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] 1. In the utility model, sewage enters the box through the water inlet pipe, and the electric air pump discharges the gas through the air guide pipe and the hollow frame from the exhaust hole. The released gas generates a large number of bubbles in the water. The motor drives the stirring shaft to rotate, which can enhance the dispersion of the bubbles, making it easier for the bubbles to better combine and adhere to the impurities in the sewage, thereby generating precipitation. The precipitated impurities fall on the filter. After completion, the second shut-off valve is opened to discharge the water through the drain pipe. Finally, the hollow frame is lifted by the hydraulic cylinder, so that the residue on the filter can be processed;

[0009] 2. The utility model is easy to use, convenient for quickly treating sewage through the flotation method, and convenient for cleaning the residue, thereby improving the efficiency and convenience of the treatment. BRIEF DESCRIPTION OF THE DRAWINGS
