Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of domestic sewage flotation machines, in particular to an air flotation machine for domestic sewage. Background Art
[0002] The flotation machine is a machine that uses small bubbles or tiny bubbles to make impurities in the medium float to the surface. This flotation device can be used for some fine particles in the water body whose specific gravity is close to that of water and whose own weight makes it difficult for them to sink or float. At present, in terms of water supply and drainage, the pre-treated water quality, except for some raw water bodies with more sand and sewage with heavier mechanical impurities, is mostly light suspended particles. After these sewage enters the flotation machine, gas is introduced from the outside into the sewage in the flotation machine, so that the bubbles adhere to the flocs, and the flocs float with the bubbles, thereby achieving rapid solid-liquid separation, and then the solid residue on the upper layer is scraped off and discharged through the scraping device.
[0003] At present, a Chinese utility model with a publication number of CN220723886U discloses a domestic sewage flotation machine, including a mixing box and a processing box, a feed pipe is installed on the left surface of the mixing box, a drive motor is installed on one side of the lower surface of the mixing box, the output shaft of the drive motor is connected to a rotating shaft, a stirring rod is installed on the upper end of the outer surface of the rotating shaft, a blade is installed on the lower side of the stirring rod, a processing box is installed on the left side of the mixing box, and a fixed plate is installed on the left side of the processing box. This domestic sewage flotation machine is provided with a rotating shaft, a stirring rod and a blade. When in use, the stirring rod on the rotating shaft stirs the inside of the mixing box by rotating the rotating shaft, so that the domestic sewage and the agent are fully mixed, and the vortex generated by the stirring rod during stirring will move the larger impurities or suspended matter in the sewage along the rotating shaft to the bottom of the mixing box, and at the same time, it is crushed by the blade on the rotating shaft into smaller particles for the flotation machine to process.
