[0002] The air flotation machine is a water treatment equipment that produces a large number of fine bubbles in the water by a dissolved air system, so that the air is attached to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state with a density less than that of water. The buoyancy principle is used to make it float on the water surface, thereby achieving solid-liquid separation. The advantages of the air flotation machine are that it is a solid-liquid separation equipment with low investment, extremely small floor space, high degree of automation, and easy operation and management.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When impurities float to the water surface and foam scum is formed, the air pump conveys air into the connecting box, and the air in the connecting box is conveyed into the blowing branch pipe, and then the air is blown out from the blowing hole. Since the blowing hole is arranged at an angle with the horizontal plane and blows out obliquely upward, the foam scum can be moved along the liquid surface in the direction of the first baffle plate through the air, and finally the foam scum will cross the first baffle plate and fall along the guide plate to the first filter plate.

As the push plate moves, the foam scum in the area can be squeezed, and the squeezed sewage leaves the area through the second filter plate. Finally, the sewage passes through the first filter plate again to clean the first filter plate, avoiding blockage caused by a large amount of foam scum accumulated on the first filter plate. In addition, the foam scum can be squeezed and dehydrated simultaneously during cleaning to further reduce the water content of the foam scum, which is convenient for subsequent treatment of the foam scum.

[0017] 3. The second servo module drives the moving plate and the pushing plate to move synchronously. The first water pump extracts the sewage in the shell and sprays it to the first filter plate above through the nozzle. The area where the sewage washes the first filter plate is the internal area of ​​the pushing plate. When the pushing plate moves, a large amount of foam scum will move. The remaining small amount of foam scum will be driven by the sewage sprayed upward to move upward and leave the first filter plate. Due to the movement of the pushing plate, the foam scum will fall into the collection filter basket when it falls. After long-term use, the collection filter basket can be taken out and cleaned through the mounting frame, thereby realizing the backwashing of the first filter plate and being able to collect the foam scum encountered in the backwashing to avoid the foam scum from contacting the first filter plate again, further improving the cleaning effect of the foam scum on the first filter plate, and ensuring the filtering effect of the first filter plate.

The bottom surface of the body 1 is connected with multiple groups of saturated air-water branch pipes 6 that are spaced apart and distributed in parallel. The saturated air-water branch pipe 6 is perpendicular to the second baffle plate 7 and has multiple groups of air holes on the saturated air-water branch pipe 6. The air holes are spirally distributed along the length direction of the saturated air-water branch pipe 6. A third baffle plate 8 is fixedly installed in the shell 1. The third baffle plate 8 is located on the side of the second baffle plate 7 away from the first baffle plate 2. The third baffle plate 8 is the same depth as the shell 1 and has multiple groups of water flow grooves 9 on one end close to the bottom surface of the shell 1. The end of the shell 1 away from the first baffle plate 2 is connected with a drain pipe 11; A plurality of blow branch pipes 15 are fixedly installed in the shell 1 and are distributed in parallel. The plurality of blow branch pipes 15 are connected to a connecting box 13 fixedly installed on the side of the shell 1. The connecting box 13 is connected to an air pump 14. A blow hole 16 is provided on the blow branch pipe 15. The height of the blow branch pipe 15 is the same as that of the first baffle 2. The blow branch pipe 15 is distributed between the first baffle 2 and the third baffle 8. The blow hole 16 is located on the side of the blow branch pipe 15 close to the first baffle 2. The blow hole 16 is provided in a plurality of groups and is provided at an angle with the horizontal plane. A guide plate 1 is fixedly installed on the side of the first baffle 2 away from the second baffle 7. 8, the guide plate 18 and the first baffle plate 2 are arranged at an angle, a horizontally distributed first filter plate 19 is fixedly installed at one end of the guide plate 18 away from the first baffle plate 2, a second water pump 36 and a liquid level meter 35 located below the first filter plate 19 are fixedly installed in the shell 1, a water outlet end of the second water pump 36 is communicated with the area between the first baffle plate 2 and the third baffle plate 8, a fourth baffle plate 10 is fixedly installed in the shell 1, the fourth baffle plate 10 is located on the side of the third baffle plate 8 away from the first baffle plate 2, the height of the fourth baffle plate 10 is lower than the third baffle plate 8, and a plurality of groups of triangular-structured protrusions are fixedly installed on the end surface of the fourth baffle plate 10.

[0030] In actual application of this embodiment, the area between the first baffle 2 and the third baffle 8 in the shell 1 is the separation chamber, and the area between the third baffle 8 and the side wall of the shell 1 is the clean water chamber. The sewage enters the separation chamber through the water inlet main pipe 3 and the water inlet branch pipe 4. The water level in the separation chamber is the same as the height of the first baffle 2. At the same time, the material pump 12 transports the saturated air water to the saturated air water main pipe 5, and then the saturated air water is ejected from the air holes on the saturated air water branch pipe 6. The saturated air water forms highly dispersed tiny bubbles, which adhere to the pollutants in the sewage, making their buoyancy greater than the weight. force and buoyancy resistance, so that it floats to the water surface and forms foam scum. Since the air holes are spirally distributed, a spiral water flow will be formed when discharging saturated air water, which plays the role of a stirrer. The sewage entering the separation chamber is blocked by the second baffle 7 to prevent it from directly entering the clean water chamber, so that the sewage can contact with the bubbles. The sewage after the impurities are separated passes through the water flow trough 9 into the clean water chamber, and then overflows through the fourth baffle 10 and the triangular convex block on its top to ensure the quality of the water. The treated sewage is then discharged through the drain pipe 11; When impurities float to the water surface and form foam scum, the air pump 14 delivers air to the connecting box 13, and the air in the connecting box 13 is delivered to the blowing branch pipe 15, and then the air is blown out from the blowing hole 16. Since the blowing hole 16 is set at an angle with the horizontal plane and blows out obliquely upward, the foam scum can be moved along the liquid surface in the direction where the first baffle plate 2 is located through the air, and finally the foam scum will pass over the first baffle plate 2 and fall along the guide plate 18 to the first filter plate 19. A shielding plate 17 is fixedly installed in the shell 1 to prevent the foam scum from The foam scum is blown away, and the foam scum moves under the action of air blowing, which prevents a large amount of sewage from following the foam scum over the first baffle 2, reduces the water content of the foam scum, and then filters the foam scum through the first filter plate 19 to further reduce the water content of the foam scum, which is convenient for the transportation and treatment of the foam scum. The sewage will pass through the first filter plate 19, and the height of the water level below the first filter plate 19 is detected by the liquid level meter 35. When the water level reaches the set threshold, the second water pump 36 extracts the sewage and transports it to the separation chamber.

[0031] like Figure 1-Figure 6 As shown, a solar powered air flotation device provided by the present invention is provided. A push plate 26 of a frame-type structure is arranged in the shell 1. The push plate 26 is in sliding contact with the inner wall of the shell 1 and the first filter plate 19. The length of the push plate 26 is the same as the width of the first filter plate 19. A first servo module 28 is arranged in the shell 1. The first servo module 28 drives the connecting plate 27 to move along the length direction of the first filter plate 19. The connecting plate 27 is fixedly connected to the push plate 26.

[0032] Specifically, a telescopic member 24 is fixedly installed on the side of the shell 1, and a U-shaped bracket 21 is fixedly installed on the output end of the telescopic member 24. Two sets of parallel side walls of the bracket 21 extend into the shell 1 and a through groove 23 for the bracket 21 to pass through is opened on the side wall of the shell 1. The bracket 21 is fixedly installed with a second filter plate 20 and a closing plate 22. The second filter plate 20 is located at the end of the bracket 21. The second filter plate 20 is in sliding contact with the side wall of the shell 1 and the first filter plate 19. The shapes of the second filter plate 20 and the closing plate 22 are consistent with the through groove 23. In the initial state, the second filter plate 20 is in contact with the guide plate 18 and the closing plate 22 is located in the through groove 23.

[0033] Specifically, cover plates 25 are fixedly mounted on both side walls in the housing 1 , and the cover plates 25 are in sliding contact with a surface of the second filter plate 20 away from the first filter plate 19 .

[0034] In actual application of this embodiment, the first servo module 28 drives the push plate 26 to move to one side through the connecting plate 27. When the push plate 26 moves, it can push the foam scum on the first filter plate 19 to move to the end. The end position of the first filter plate 19 is not provided with a filter hole and is a complete plane structure. When the push plate 26 enters the range where the cover plate 25 is located, the push plate 26, the second filter plate 20, the first filter plate 19 and the side wall of the shell 1 form a closed area. With the movement of the push plate 26, the foam scum in the area can be squeezed, and the squeezed sewage leaves the area through the second filter plate 20. Finally, the sewage passes through the first filter plate 19 again, so as to realize the cleaning of the first filter plate 19 and avoid the blockage of a large amount of foam scum accumulated on the first filter plate 19. In addition, the foam scum can be squeezed and dehydrated synchronously during cleaning to further reduce the water content of the foam scum, which is convenient for the subsequent treatment of the foam scum. After the extrusion is completed, the push plate 26 moves to make the side of the second filter plate 20 flush with the side of the push plate 26, and then the telescopic member 24 drives the second filter plate 20 and the closing plate 22 to move simultaneously through the bracket 21. At this time, the second filter plate 20 can push the extruded foam scum to move and discharge it from the through groove 23, thereby realizing automatic cleaning of the foam scum and avoiding adhesion of the foam scum on the push plate 26, thereby improving the cleaning efficiency of the foam scum. After the cleaning is completed, the second filter plate 20 is reset, and the push plate 26 can move in the other direction at this time, and the above steps are repeated to clean the foam scum.

[0035] In an example of the present invention, the telescopic member 24 is an electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder, and the second filter plate 20 is driven to move by the electric telescopic rod.

[0037] In actual application of this embodiment, the second servo module 32 drives the moving plate 31 and the pushing plate 26 to move synchronously, the first water pump 33 extracts the sewage in the shell 1 and sprays it to the first filter plate 19 above through the nozzle 34, and the area where the sewage washes the first filter plate 19 is the internal area of ​​the pushing plate 26. When the pushing plate 26 moves, a large amount of foam scum will move, and the remaining small amount of foam scum will be driven by the sewage sprayed upward to move upward and leave the first filter plate 19. Due to the movement of the pushing plate 26, the foam scum will fall into the collecting filter basket 30 when it falls. After long-term use, the collecting filter basket 30 can be taken out and cleaned through the mounting frame 29, thereby realizing the backwashing of the first filter plate 19, and being able to collect the foam scum encountered in the backwashing, so as to prevent the foam scum from contacting the first filter plate 19 again, further improving the cleaning effect of the foam scum on the first filter plate 19, and ensuring the filtering effect of the first filter plate 19.
