Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an air flotation device. Background Art

[0002] Currently, industrial production processes often generate large amounts of wastewater. Directly discharging it into rivers can cause significant pollution and unnecessary losses. Therefore, wastewater treatment is necessary before it is released. Flotation machines are often used for wastewater treatment. Flotation machines use microbubbles of air (or other gases) to attach to solid particles (suspended matter) in the liquid being treated, causing them to rise to the surface. This separates the contaminated solids from the water, purifying it. The microbubbles envelop the solid particles, which then float to facilitate their collection.

[0003] Currently, a Chinese utility model, publication number CN219670199U, discloses a flotation device comprising a flotation tank, a filtering mechanism fixedly connected to the lower end of the flotation tank, a fixed frame fixedly connected to the middle portion of the upper end of the flotation tank, a motor fixedly mounted on the upper end of the fixed frame, a rotating rod fixedly connected to the output end of the motor, the rotating rod being a hollow structure, a plurality of stirring rods fixedly connected to the outer surface of the rotating rod, each of the stirring rods being connected to the interior of the rotating rod, and each of the stirring rods having a plurality of air outlet holes formed on the outer surface, an air intake mechanism fixedly connected to the upper end of the flotation tank, a collection port formed at the left and right upper ends of the flotation tank, and a water inlet provided at the upper middle portion of the left and right ends of the flotation tank. The flotation device described in this utility model can accelerate the fusion of microbubbles with solid particles in sewage, improve the fusion efficiency, and simultaneously improve sewage discharge efficiency.

[0035] The working principle and use process of the present invention are as follows: when in use, the sewage in the flotation tank 1 is first filtered through the filter plate 3 to separate the sediment from the sewage. When the filter plate 3 needs to be replaced after a long period of use, the sealing cover 5 on the inner wall of the replacement groove 4 is removed, and then the servo motor 71 drives the screw 72 to rotate, which can drive the adjustment block 74 to move in the profile frame 73, thereby adjusting the position of the replacement frame 6, and when the adjustment block 74 moves, it drives the ball 10 to follow the movement, so that the ball 10 can roll on the inner wall of the slide groove 9, thereby improving the smoothness of the adjustment block 74 when moving. When the replacement frame 6 drives the filter plate 3 to the front side, the filter plate 3 is replaced. During movement, the scraper bar 81 can be used to scrape the surface of the filter plate 3, and the brush 83 at the bottom of the connecting plate 82 can be used to clean the filter plate 3, so that the sediment on the surface of the filter plate 3 can be cleaned to prevent the sediment from being adsorbed on the surface of the filter plate 3 and making it difficult to clean. When the surface of the filter plate 3 is cleaned, the replacement rack 6 is adjusted to the front side of the filter tank 2, and the limiting plate 12 can slide on the inner wall of the limiting groove 11, so that the replacement rack 6 can be limited, which improves the stability of the replacement rack 6 during adjustment. Then the user disassembles the filter plate 3 inside the replacement rack 6, so that the filter plate 3 can be replaced.

[0036] To sum up: this flotation device, by providing a replacement slot 4, a replacement rack 6 and an adjustment component 7, can effectively enable the replacement rack 6 to support and filter the filter plate 3, and the adjustment component 7 drives the replacement rack 6 to move forward through the replacement slot 4, so that the filter plate 3 on the inner wall of the replacement rack 6 can be disassembled and replaced, solving the problem that after the filter plate has been used for long-term filtering, it is difficult for the user to replace the filter plate due to the lack of a replacement structure, and it is difficult to maintain the filter plate.
