Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment technology, specifically to an air flotation machine for industrial wastewater treatment. Background Technology

[0002] Currently, the micro-nano high-efficiency air flotation machines used for industrial wastewater treatment on the market have relatively simple structures and lack air dispersion structures. This results in insufficient contact between gas and water during wastewater treatment, leading to poor treatment efficiency. Based on this, Chinese Patent Publication No. CN217578365U discloses a micro-nano high-efficiency air flotation machine for industrial wastewater treatment. This patented technology introduces wastewater into the treatment tank through an inlet pipe, then starts an aerator. The aerator generates dissolved gas, which is conducted through a conduit to the interior of an exhaust pipe and then discharged from the exhaust pipe. Inside the exhaust pipe, a connecting rod is connected to a fixed plate, and multiple air dispersion blades are movably installed at the bottom of the connecting rod. When the dissolved gas is discharged through the exhaust pipe, it drives the air dispersion blades to rotate, thereby accelerating the contact between dissolved gas and water and improving treatment efficiency.

[0003] However, as can be seen from the specification and accompanying drawings of the aforementioned patented technology, when the patented technology is used in practice, it scrapes off the light flocs on the water surface by setting a reciprocating scraper on the surface of the sewage. Although this method can achieve the effect of scraping off the light flocs on the water surface, because the light flocs are relatively light, when scraping them off with the scraper, the light flocs tend to spread out to both sides of the water surface. The lower the content of light flocs, the more obvious the effect of spreading out to both sides. However, it is impossible for personnel to effectively clean the light flocs on the water surface. Therefore, it has certain shortcomings in its use.

[0004] In conclusion, it is necessary to invent an air flotation machine for industrial wastewater treatment. Utility Model Content

[0005] Therefore, this utility model provides an air flotation machine for industrial wastewater treatment to solve the problem that, due to the light weight of the flocs, when scraped off with a scraper, the flocs tend to spread out to both sides of the water surface, and the lower the content of the flocs, the more obvious the spreading effect is. However, it is impossible for personnel to effectively clean the flocs on the water surface.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an air flotation machine for industrial wastewater treatment, comprising a treatment tank, a partition fixed on the right side of the inner wall of the treatment tank, an aeration component disposed between the left side of the inside of the treatment tank and the partition, and a decontamination component disposed on the inner wall of the treatment tank above the aeration component.

The electrically controlled telescopic rod 400 can be controlled by a controller to start and stop, ensuring that both top connecting frames 410 can simultaneously drive the strip frame 200. The partition 130 moves up and down. A side mounting frame 300 is fixed between the right side of the outer wall of the partition 130 and the right side of the inner wall of the treatment tank 100, and below the sewage outlet. A filter plate layer 310 for filtering sewage is slidably connected to the opposite side of the two side mounting frames 300. The side mounting frames 300 are set to place the filter plate layer 310. The three sets of filter plate layers 310 can filter the absorbed wastewater and light flocs. The filtered wastewater can be returned to the sewage treatment equipment through the drain outlet opened at the bottom right side of the outer wall of the treatment tank 100.

[0027] The usage process of this utility model is as follows: Those skilled in the art can assemble the device according to the above description, then connect all the electrical equipment to an external power supply, and connect the corresponding controller through a data cable so that personnel can control the operation of the device.

[0028] Then, personnel can transport the wastewater to be treated to the cleaning tank on the left side of the treatment tank 100 through the inlet pipe on the upper left side of the front end of the treatment tank 100. Then, the aerator 110 is powered on, so that the aerator 110 can generate dissolved air. The dissolved air will be conducted to the inside of the aeration branch pipe 121 through the main air pipe 120, and then discharged from the aeration branch pipe 121. The dissolved air will combine with the impurities in the wastewater to form light flocs that float on the surface of the wastewater. Then, personnel can control the electric telescopic rod 400 to place the support airbag 240 on the liquid surface through the top connecting frame 410. Then, after being powered on, the sewage pump 241 can pump water to the top of the liquid surface through the horizontal plate 242. The process involves suction, allowing light flocs and wastewater to enter the discharge port through the infusion hose. From the discharge port, the wastewater is transported to the filter plate layer 310. Multiple filter plates 310 can filter the light flocs and wastewater. The filtered wastewater can be returned to other wastewater treatment equipment through the drain outlet at the bottom right side of the outer wall of the treatment tank 100. The drive motor 250, when powered on, drives the ball screw 210 to rotate through the pulley mechanism 251, which in turn drives the threaded moving seat 230 to move the support airbag 240 left and right, thereby increasing the suction range of the sludge pump 241.

[0029] After prolonged filtration, the purified wastewater can be discharged through the drain pipe at the bottom of the inlet pipe. Alternatively, personnel can open the sealing plate located on the right side of the front end of the outer wall of the treatment tank 100 at the corresponding position of the filter plate layer 310, and then pull out the filter plate layer 310 for cleaning.

[0030] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
