Description

Technical Field

[0001] The invention relates to the technical field of industrial wastewater treatment, and in particular to an air flotation purification device for industrial wastewater treatment and a purification method thereof. Background Art

[0002] Air flotation is a water treatment technology mainly used for solid-liquid separation and removal of suspended matter. It injects tiny bubbles into the water, causing solids or grease suspended in the water to adhere to the buoyancy of the bubbles, thereby bringing them to the surface of the water to form scum, which is then removed by scraping or other means, thereby achieving the purpose of purifying water quality.

[0003] For example, a Chinese invention patent (CN 115594245 A) discloses an air flotation purification device for industrial wastewater treatment, which records: "When the height of the water surface changes, the limit block moves in the strip groove, so that the height of the mounting frame and the scraper can change with the change of the water surface, so that the scraper is always in contact with the water surface, and the residue on the water surface is scraped off. The drive shaft is driven to rotate by an external power device, which has a good cleaning effect on the residue." It also records: "The existing scraping equipment cannot be adjusted according to the change of the liquid level during the scraping process. In the specific purification process, the liquid level will inevitably rise and fall, and the scraper cannot flexibly change its height according to the change of the liquid level. Therefore, the scraping effect of the scraper during the scraping process is greatly reduced, and the bubbles and scum on the sewage surface cannot be removed in time, which will affect the purification efficiency." Technical problems.

[0004] In summary, it can be seen that the prior art utilizes floating blocks to drive the scraper to change with the changes in the water surface. However, this method has the following technical problems: However, during the actual use of the device, the suspended matter on the liquid surface may gather more, so that the floating blocks are above the suspended matter, and the height of the scraper from the liquid surface is relatively high, thereby reducing the cleaning efficiency of the suspended matter. For this reason, the present application proposes an air flotation purification device and a purification method for industrial wastewater treatment, in order to solve the technical problems mentioned in the above patents and provide a new technical solution. Summary of the invention

[0005] Based on this, it is necessary to provide an air flotation purification device for industrial wastewater treatment and a purification method thereof in response to the above-mentioned technical problems. The height of the support frame can be changed by rotating the adjusting rod, and then the height of the sliding block can be changed through the partition plate, and finally the height of the claw bucket can be changed. The height of the claw bucket can be adjusted according to the depth of the suspended matter on the liquid surface, and the suspended matter on the liquid surface can be effectively collected, avoiding the situation where the height of the claw bucket changes due to a large amount of suspended matter on the liquid surface, resulting in low efficiency in cleaning the suspended matter. The bucket shape design of the claw bucket increases the single collection amount of suspended matter, thereby improving the cleaning efficiency of the suspended matter, and the leakage hole reduces the content of suspended water put into the storage leakage frame, thereby improving the practicability of the device.

After the height of the claw bucket 23 is adjusted to a suitable position, the claw bucket 23 collects the suspended matter on the liquid surface as it moves. After the adjusting baffle 22 contacts the fixed baffle 46, as the claw bucket 23 moves further, the fixed baffle 46 squeezes the adjusting baffle 22, and then the torsion spring 21 is deformed.
