Description

Technical Field

[0001] The utility model relates to the technical field of air floatation machines, in particular to a high-efficiency and energy-saving air floatation machine. Background Art

[0002] Flotation machine is a water treatment equipment that uses tiny bubbles to combine with suspended matter in water to form a state with a density lower than that of water, and achieves solid-liquid separation through buoyancy. The working principle of the flotation machine is based on the principle of buoyancy. By generating a large number of tiny bubbles in water, these bubbles will attach to the suspended matter, reducing its overall density and rising to the water surface using buoyancy, thereby achieving solid-liquid separation.

[0003] The basic principle of current flotation machines is to add chemicals to the wastewater to be treated. After the chemicals and wastewater aggregate, floccules float on the water surface. Finally, the flotation machine scrapes the flocs out of the water through a scraper. However, after the scrapers of current flotation machines scrape the flocs out of the water, the flocs fall into the collection tank due to gravity. This method does not completely remove the flocs on the scraper surface, thereby reducing the floc removal efficiency of the flotation machine. Therefore, a new type of high-efficiency and energy-saving flotation machine is needed to solve the above problems. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0023] The present embodiment provides an air flotation machine, which is mainly used to solve the problem that after the scraper of the current air flotation machine scrapes the flocculent material out of the water, the flocculent material falls into the inside of the collection tank by gravity. This method makes the flocculent material on the scraper surface not completely removed, thereby reducing the flocculent removal efficiency of the air flotation machine, and provides the following technical solutions. Figures 1-4 Give detailed instructions:

[0024] A flotation machine includes: a processing chamber 1 with a stirring tank 2, an air flotation tank 3, a debris removal tank 4, and a sludge tank 5 that are interconnected on the surface, and a stirring unit 6 is provided inside the stirring tank 2. Therefore, after the user passes sewage and flocculant into the stirring tank 2 (the flocculant can be added in various ways, and can be added through a water pump in conjunction with a liquid adding pipe), the sewage and flocculant can be stirred and mixed by the stirring unit 6. After the stirring is completed, the sewage will enter the air flotation tank 3 and be covered by the bubbles generated by the aerator 7 inside the air flotation tank 3, thereby driving the flocculants inside to float on the water surface. A controller 8 is fixedly installed on the surface of the processing chamber 1, and the controller 8 is electrically connected to the aerator 7. After the sewage enters the sludge tank 5, the scrapers 9 above the sludge tank 5 will be driven by the first driving unit 10 to move along the length of the treatment chamber 1, and the flocculants floating on the surface of the sewage will be brought into the sludge tank 5. The remaining sewage will be discharged from the drainage hole at the bottom of the treatment chamber 1 (the drainage hole is provided with a control valve for controlling its conduction state) and enter the next treatment link. It should be noted that it also includes a first driving unit 10 and a plurality of torsion springs 11. The first driving unit 10 is used to rotate the plurality of scrapers 9 respectively through the plurality of torsion springs 11 and control the plurality of scrapers 9 to move above the treatment chamber 1, and the inner wall of the treatment chamber 1 is fixedly installed with a friction Plate 12, so in the process of several scrapers 9 moving, they will touch the resistance plate 12, under the action of the torsion spring 11, after the scraper 9 contacts the resistance plate 12, it will be driven by the resistance plate 12 and flipped over. In this process, the resistance plate 12 will slide on the surface of the scraper 9, thereby scraping off the flocculent matter. The main components of the stirring unit 6 are: a mounting frame 61 fixedly mounted on the inner wall of the stirring tank 2, and a stirring rod 62 is connected to the surface of the mounting frame 61. The user controls the output end of the first motor 63 to rotate through the controller 8, which can drive the stirring rod 62 fixed to the output end of the first motor 63 to rotate, thereby achieving the stirring of the sewage, wherein the first drive unit 1 0 is mainly composed of: a second motor 104 fixedly mounted on the surface of the processing bin 1, and a plurality of first transmission wheels 101 are rotatably mounted on the inner wall of the processing bin 1. The user controls the output end of the second motor 104 to rotate through the controller 8, thereby driving one of the first transmission wheels 101 to rotate, thereby driving the two transmission belts 102 to move along their own length. Because a plurality of rubber blocks 103 are fixedly mounted on the surfaces of the two conveyor belts, and the plurality of rubber blocks 103 are rotatably mounted on a plurality of scrapers 9 through a plurality of torsion springs 11, when the two conveyor belts move, the plurality of scrapers 9 will be synchronously driven to move, thereby scraping off the flocs on the surface of the sewage.

[0025] By providing a stirring tank 2, an air flotation tank 3, a de-impurity tank 4, and a sludge tank 5 which are interconnected on the surface of the treatment bin 1, the user pours sewage from the stirring tank 2 and adds flocculant at the same time, and then stirs the sewage inside the stirring tank 2 through the stirring unit 6, so that the sewage and the flocculant can be fully mixed. Then, the mixed sewage will enter the air flotation tank 3, come into contact with the bubbles released by the aerator 7, and continue to enter the interior of the de-impurity tank 4. The flocs inside the sewage will float on the water surface and be scraped into the interior of the sludge tank 5 by the scraper 9 driven by the first driving unit 10. In this process, the surface of the scraper 9 will first contact the surface of the resistance plate 12, and then the surface slides over the resistance plate 12 and is reset under the action of the torsion spring 11, so that the flocs on the surface of the scraper 9 can be scraped off by the resistance plate 12, thereby ensuring the cleaning effect of the flocs on the surface of the scraper 9.

[0026] By opening a sludge trough 5 on the surface of the processing bin 1 and setting a conveyor belt 16 on the inner wall of the sludge trough 5, during subsequent use, the user can control the output end of the third motor 172 to rotate through the controller 8, driving one of the second transmission wheels 171 to rotate, and further realizing the driving of the conveyor belt 16 along its own length, thereby bringing the sludge from the surface of the conveyor belt 16 out of the processing bin 1.

[0027] like Figure 4 As shown, in some embodiments, after the scraper 9 slides against the surface of the resistance plate 12 , the torsion spring 11 is driven to twist, thereby scraping off the flocculent matter on the surface of the scraper 9 .

[0028] like Figures 1 to 4 As shown, in some embodiments, a conveyor belt 16 is provided inside the sludge tank 5. When in use, the user can control the conveyor belt 16 to move along its own length through the second drive unit 17, thereby bringing the flocculent material on the surface of the conveyor belt 16 out of the interior of the processing chamber 1, wherein the main components of the second drive unit 17 are: a third motor 172 fixedly mounted on the surface of the processing chamber 1, and at the same time, a plurality of second transmission wheels 171 are rotatably mounted on the inner wall of the sludge tank 5, and the plurality of second transmission wheels 171 are all attached to the surface of the conveyor belt 16. Therefore, after the user controls the output end of the third motor 172 to rotate through the controller 8, it will drive one of the second transmission wheels 171 to rotate, thereby driving the conveyor belt 16 to move along its own length. It should be noted that: the surfaces of the two first transmission wheels 101 are fixedly mounted with the same balance bar 18, so that when the output end of the second motor 104 rotates, it will drive the two first transmission wheels 101 to rotate, ensuring that the two transmission belts 102 move along their own length.

[0029] The workflow of this utility model:

[0030] First, the user injects sewage and flocculant into the interior of the stirring tank 2, and controls the output end of the first motor 63 to rotate through the controller 8, which can drive the stirring rod 62 to rotate, thereby achieving mixing of the sewage and flocculant. After the mixing is completed, the sewage will enter the interior of the flotation tank 3 and will be wrapped by the bubbles emitted by the aerator 7. The flocculants inside will also be brought out and float on the water surface.

[0031] Secondly, after the sewage enters the impurity removal tank 4, the several first transmission wheels 101 driven by the output end of the second motor 104 will synchronously drive the two transmission belts 102 to move, and further drive the several scrapers 9 installed on the surface of the two transmission belts 102 through several torsion springs 11 to move, thereby achieving the scraping of flocs. Finally, after the several scrapers 9 pass through the resistance plate 12, the resistance will successively resist the surface of the several scrapers 9, causing them to swing. In this process, the flocs on the surface of the several scrapers 9 will be scraped off.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
