Technical Field

[0001] The present application relates to the technical field of wastewater treatment, and in particular to an electrolytic flotation oil removal self-cleaning treatment device. Background Art

[0002] The flotation method uses dispersed tiny bubbles as carriers to adhere to pollutants in wastewater, causing the pollutants to float to the surface of the water to form foam, and then the foam is scraped off to achieve purification. The existing flotation methods mainly include impeller flotation and electrolytic flotation.

[0003] In the prior art, there is an efficient electrolytic flotation device for wastewater treatment with a publication number of CN217148670U. The motor drives the cleaning plate to rotate, and the bubbles with pollutants attached can be collected into the sewage collection box. The air blowing pipe is set to blow the bubbles toward the cleaning plate, which is conducive to the cleaning plate collecting bubbles.

[0004] However, during the use of the device, the water flow effect at the wall of the flotation tank is poor, the treatment time is long, and when the oil-containing foam floats above the flotation tank, it breaks and splits when it hits the wall of the flotation tank, leaving residues. The oil stains adhere to the wall of the flotation tank and are difficult to clean, affecting the purification effect.

[0005] Therefore, the present application provides an electrolytic flotation oil removal self-cleaning treatment device to meet the needs. Utility Model Content

[0006] In view of this, the purpose of the present application is to provide an electrolytic flotation oil removal self-cleaning treatment device, which can enhance the flow of water by aeration at the wall of the box, extract the oil-containing foam through the water flow in the overflow pipe, and clean it with a scraper to improve the purification effect.

[0007] In order to solve the above technical problems, this application provides the following technical solutions:

[0009] Preferably, the vertical projection of the overflow pipe is in the shape of a "mouth", and the overflow pipe is attached to the inner side wall of the box body.

[0010] Preferably, the pressure equalizing pipe is arranged around the box body.

[0011] Preferably, an electric push rod is fixedly connected to the top of the overflow pipe, a connecting rod is fixedly connected to the telescopic end of the electric push rod, and the other end of the connecting rod is fixedly connected to a scraper.

[0013] Preferably, the vertical projection of the aeration pipe is in the shape of a "mouth", and the outer diameter of the aeration pipe is the same as the inner diameter of the box body.

[0014] Preferably, the water pump is arranged below the pressure equalizing pipe.

[0015] Compared with the prior art, the present application has at least the following beneficial effects:

[0016] In the above solution, by arranging the overflow pipe, the pressure equalizing pipe and the water pump, when the oil-containing foam generated in the box body continuously increases in height to exceed the opening of the overflow pipe, the oil-containing foam can continuously overflow into the overflow pipe.

[0018] In the above solution, by arranging the aeration pipe and the air pump, when the air pump works, the aeration pipe continuously generates bubbles at the lower position of the inner side wall of the box body, enriching the number of bubbles. The bubbles float along the inner side wall of the box body and finally accumulate at the opening position of the overflow pipe. The water flow generated by the floating of this part of the bubbles further pushes the oil-containing foam into the overflow pipe to improve the treatment effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The electrode 101 includes a cathode and an anode that are staggered and used for electrolyzing wastewater. When the electrode 101 is energized, highly concentrated bubbles are generated at the center of the bottom of the box 1, so that pollutants are attached by the bubbles and float to the upper position of the box 1.

[0029] The liquid level inside the box body 1 is controlled at the opening of the overflow pipe 2, and the oil-containing foam overflows into the overflow pipe 2. The liquid in the pressure equalizing pipe 401 is extracted by the water pump 4. The pressure equalizing pipe 401 is provided with a plurality of openings so that the liquid in the overflow pipe 2 can flow fully. The water outlet of the water pump 4 is connected to the filter box 3, and the filter box 3 further processes the oil-containing foam to achieve an efficient purification effect.

[0030] The overflow pipe 2 is open on the side. When the residue generated by the oil-containing foam hitting the inner wall of the overflow pipe 2 adheres to the inner wall of the overflow pipe 2, the scraper 201 that can move up and down scrapes the residue to the bottom end inside the overflow pipe 2, and the water flow flowing through the bottom end inside the overflow pipe 2 flushes this part of the residue into the filter box 3;

[0031] By controlling the liquid level height of the sewage in the box body 1, a good purification effect is achieved. At the same time, with the cooperation of the air pump 6 and the aeration pipe 5, the aeration pipe 5 is arranged in contact with the wall surface of the box body 1. The aeration pipe 5 further enriches the number of bubbles, and at the same time promotes the flow of sewage, so that the sewage can be mixed evenly to achieve the purpose of improving the purification efficiency.
