Description

Technical Field

[0001] This utility model relates to the field of phosphorus removal technology, specifically a phosphorus removal device for aluminum fluoride solution. Background Technology

[0002] Phosphorus-containing wastewater is commonly found in industries such as surface treatment of mechanical parts, pharmaceuticals and chemicals, aquaculture and slaughtering, as well as domestic sewage. When wastewater with excessive phosphorus levels is discharged into water bodies, it will cause ecological degradation such as eutrophication, discoloration, red tides, and fish deaths, making it an extremely serious source of environmental pollution.

[0003] The utility model patent with announcement number CN220951485U discloses a phosphorus removal device for aluminum fluoride solution, which belongs to the field of phosphorus removal technology. It solves the problem that most existing technologies directly electrolyze phosphorus removal, but wastewater often contains some impurities. If the impurities in the wastewater are not filtered, the effect of electrolytic phosphorus removal will be affected and the phosphorus removal efficiency will be reduced. The device includes a filtration mechanism, and a phosphorus removal mechanism is provided on one side of the outer wall of the filtration mechanism. In this invention, through the cooperation of the filtration and dephosphorization mechanisms, wastewater is first fed into the filtration chamber through the inlet during normal operation. Passing through the filter screen, larger impurities in the wastewater are filtered out. When the motor starts, it drives the threaded rod to rotate, causing the movable slide to move along the threaded rod, which in turn moves the cleaning brush to clean the filter screen, preventing clogging. Next, the filtered wastewater enters the reaction chamber through a transmission pipe, and aluminum fluoride solution is added through the inlet. The second motor is then started, driving the rotating column to rotate, which in turn rotates the stirring blades, ensuring a more uniform mixing of the wastewater and the aluminum fluoride solution. Finally, the electrolysis equipment is activated to remove phosphorus from the wastewater, improving the dephosphorization effect and preventing environmental pollution.

[0004] However, the above patent still has shortcomings: although the patent can remove phosphorus from wastewater, the electrodes of the electrolysis equipment are easily oxidized due to long-term immersion in water, which leads to passivation of the electrodes and affects the electrolysis effect, resulting in poor phosphorus removal.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 7 The present invention will describe the above technical solution in detail through the following embodiments:

[0028] A phosphorus removal device for aluminum fluoride solution includes: a tank 1; an inlet 2 is provided on one side of the top of the tank 1, and an outlet 3 is provided on one side of the bottom of the tank 1.

[0029] like Figures 4 to 6 As shown, the grinding mechanism 7 includes: grinding wheels 9 are provided on both sides of the electrode 6 inside the housing 1, and a rotating shaft 10 is fixedly connected to the center of each grinding wheel 9. One end of each rotating shaft 10 is rotatably connected to the connecting frame 11, and the other end of each rotating shaft 10 passes through the connecting frame 11 and extends to the gear 12, with the gears 12 meshing in pairs; the ends of two rotating shafts 10 away from the gears 12 pass through the connecting frame 11 and extend to the worm gear 13, with the worm gear 13 fixedly connected to the rotating shaft 10 respectively. A worm 14 is provided between the two worm gears 13, and both worm gears 13 mesh with the worm 14. The worm 14 is internally fixed. A flower-shaped bushing 15 is connected, and fixed blocks 16 are rotatably connected to the outer surfaces of both ends of the flower-shaped bushing 15. The fixed blocks 16 are fixedly connected to the connecting frame 11. While the flower-shaped bushing 15 rotates inside the fixed blocks 16, it drives the worm gear 14. While the worm gear 14 rotates, it drives the worm wheels 13 on both sides respectively. The two worm wheels 13 drive the rotating shaft 10 respectively. While the rotating shaft 10 rotates, it drives the other two rotating shafts 10 through the cooperation of the gear 12, so that the rotating shafts 10 on both sides of the electrode 6 rotate synchronously in opposite directions. While the rotating shaft 10 rotates, it drives the polishing wheel 9 respectively. While the polishing wheel 9 rotates, it polishes the oxide layer on the surface of the electrode 6.

[0030] like Figures 4 to 6As shown, a flower shaft 17 is slidably connected inside the flower shaft sleeve 15. A support block 18 is rotatably connected to the bottom end of the flower shaft 17. The support block 18 is fixedly connected to the housing 1. The top end of the flower shaft 17 passes through the housing 1 and extends to the first bevel gear 19.

The second bevel gear 20 is fixed to the outer surface of the output end of the first motor 21. The first motor 21 is fixedly connected to the housing 1. When the first motor 21 is started, the output end of the first motor 21 drives the second bevel gear 20. The second bevel gear 20 drives the first bevel gear 19. The first bevel gear 19 drives the flower shaft 17. The flower shaft 17 rotates through the cooperation of the support block 18. While the flower shaft 17 rotates, it also drives the flower shaft sleeve 15 to rotate.

[0031] like Figure 4 As shown, lifting blocks 22 are fixedly connected to both ends of the connecting frame 11. Slide rods 23 are fixedly connected to the top of each lifting block 22. The top ends of the slide rods 23 penetrate the housing 1 and extend to the top block 24. The top blocks 24 are fixedly connected to the slide rods 23, and the slide rods 23 are slidably connected to the housing 1. The two top blocks 24 are fixedly connected to each other via guide rails 25. A matching cylindrical block 26 is provided inside the guide rails 25. A circular plate 27 is fixedly connected to one end of the cylindrical block 26. The circular plate 27 is fixed to the outer surface of the output end of the second motor 28. A motor frame 29 is fixedly connected to the bottom of the second motor 28. The motor frame 29 is fixedly connected to the housing 1. [Starting...] The second motor 28 drives the circular plate 27 at its output end. The circular plate 27 drives the cylindrical block 26 to rotate. While rotating, the cylindrical block 26 pushes the guide rail 25 to reciprocate and lift. While lifting, the guide rail 25 drives the slide rod 23. The slide rod 23 drives the lifting block 22. The lifting block 22 drives the connecting frame 11. While lifting, the connecting frame 11 drives the grinding wheel 9 through the rotating shaft 10, so that the grinding wheel 9 continuously reciprocates and lifts on the surface of the electrode 6. While lifting, the connecting frame 11 drives the flower shaft sleeve 15 through the fixing block 16, so that the flower shaft sleeve 15 can flexibly lift and slide on the surface of the flower shaft 17.

[0032] like Figure 7As shown, the stirring mechanism 8 includes: a stirring shaft 30 rotatably connected to the center of the housing 1, the top end of the stirring shaft 30 being fixedly connected to the output end of the third motor 31, and the third motor 31 being fixedly connected to the housing 1; four sets of stirring blades 32 are fixedly connected to the outer surface of the stirring shaft 30 inside the housing 1, the four stirring blades 32 being arranged in pairs opposite to each other; a sealing sleeve 33 is fixedly connected to the housing 1 near the stirring shaft 30, the sealing sleeve 33 being adapted to the stirring shaft 30; when the third motor 31 is started, the output end of the third motor 31 drives the stirring shaft 30, and the stirring shaft 30 drives the four sets of stirring blades 32 on the surface to rotate synchronously. Since the four sets of stirring blades 32 are arranged in pairs opposite to each other, the stirring blades 32 mix the sewage and aluminum fluoride solution inside the housing 1 while causing convection between the sewage and aluminum fluoride solution inside the housing 1, thereby improving the mixing efficiency and mixing effect of the sewage and aluminum fluoride solution.

[0033] like Figure 2 and Figure 3 As shown, a limiting ring 34 is fixedly connected inside the inlet 2, and a filter cup 35 is provided inside the limiting ring 34. A handle 36 is fixedly connected to the top of the filter cup 35, so that when sewage passes through the inlet 2, the filter cup 35 can filter the impurities inside the sewage.

[0034] like Figure 1 As shown, a control box 37 with an internal touch screen is fixedly connected to the side of the housing 1 away from the water outlet 3, which makes it convenient for users to operate the device.

[0035] Working principle: The user puts sewage and aluminum fluoride solution into the tank 1 through inlet 2, and then starts the third motor 31. The output end of the third motor 31 drives the stirring shaft 30. While the stirring shaft 30 is rotating, it drives the four sets of stirring blades 32 on the surface to rotate synchronously. Since the four sets of stirring blades 32 are arranged in opposite pairs, the stirring blades 32 stir and mix the sewage and aluminum fluoride solution inside the tank 1, and at the same time, cause the sewage and aluminum fluoride solution inside the tank 1 to convect, which improves the mixing efficiency and mixing effect of sewage and aluminum fluoride solution. It can stir sewage and aluminum fluoride solution, and at the same time, the reverse arrangement of the blades causes the liquid inside the device to convect, thereby improving the mixing efficiency and mixing effect of sewage and aluminum fluoride solution.

[0036] When the surface of electrode 6 is oxidized and passivated, the first motor 21 and the second motor 28 are started. The output end of the first motor 21 drives the second bevel gear 20, the second bevel gear 20 drives the first bevel gear 19, and the first bevel gear 19 drives the spiral shaft 17. The spiral shaft 17 rotates through the cooperation of the support block 18. While the spiral shaft 17 rotates, it drives the spiral shaft sleeve 15 to rotate. While the spiral shaft sleeve 15 rotates inside the fixed block 16, it drives the worm gear 14. While the worm gear 14 rotates, it drives the worm wheels 13 on both sides. The two worm wheels 13 drive the rotating shaft 10. While the rotating shaft 10 rotates, it drives the other two rotating shafts 10 through the cooperation of the gear 12, so that the rotating shafts 10 on both sides of electrode 6 rotate synchronously in opposite directions. While the rotating shafts 10 rotate, they drive the grinding wheel 9. The output end of the second motor 28 drives the circular plate 27. The circular plate 27 drives the cylindrical block 26 to rotate. While the cylindrical block 26 rotates, it pushes the guide rail 25 to reciprocate and lift. While the guide rail 25 is rising and falling, it drives the slide rod 23, which in turn drives the lifting block 22. The lifting block 22 then drives the connecting frame 11. As the connecting frame 11 rises and falls, it drives the grinding wheel 9 via the rotating shaft 10, causing the grinding wheel 9 to reciprocate up and down on the surface of the electrode 6. Simultaneously, the connecting frame 11 rises and falls, which in turn drives the flower shaft sleeve 15 via the fixing block 16, allowing the flower shaft sleeve 15 to slide flexibly up and down on the surface of the flower shaft 17. This allows the grinding wheel 9 to reciprocate up and down while rotating, thereby polishing the oxide layer on the surface of the electrode 6. Polishing the oxide layer on the electrode surface prevents electrode passivation, improves the electrolysis effect, and thus improves the phosphorus removal effect. This solves the problem that although existing aluminum fluoride solution phosphorus removal devices can remove phosphorus from wastewater, the electrodes of the electrolysis equipment are easily oxidized due to long-term immersion in water, leading to electrode passivation and affecting the electrolysis effect, resulting in poor phosphorus removal.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
