Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for phosphate mining. Background Technology

[0002] Current phosphorus-containing wastewater treatment mainly relies on traditional biochemical and physicochemical technologies, which suffer from problems such as long treatment processes, low phosphorus removal efficiency, and large sludge production. While chemical precipitation is widely used, it requires large amounts of reagents and is prone to secondary pollution. Adsorption and membrane technologies are costly and unsuitable for wastewater with high loads and large fluctuations. In particular, the lack of rapid phosphorus recovery and immediate water neutralization capabilities restricts their efficient application. In existing technologies, although sedimentation efficiency can be improved through dewatering, the sludge treatment before dewatering is relatively simple, easily leading to sludge blockage of the dewatering device. Furthermore, the dewatering method is not stable enough, resulting in inconsistent overall sedimentation efficiency.

[0003] Patent CN217051859U discloses a wastewater treatment device for phosphate mining, including a filtration and decomposition upper tank. A wastewater feeding mechanism is fixedly installed on one side of the upper outer surface of the filtration and decomposition upper tank, and a dissolving drug addition component is fixedly installed inside one side of the filtration and decomposition upper tank. A sedimentation lower tank is fixedly connected to the lower outer surface of the filtration and decomposition upper tank. The dissolving drug addition component facilitates the addition of wastewater treatment drugs into the treatment tank, resulting in better dissolution of the wastewater. During use, a sealed support box provides support for the support side plate and facilitates the installation of a cylinder lifting rod, which can adjust the height of the drug tank. A sediment discharge mechanism facilitates the discharge of sediment from the sedimentation lower tank without causing blockages. While this patent solves the above problems, the sludge treatment before sedimentation is relatively simple, and blockages still occur.

The mixture neutralizes the phosphorus. The feed hopper 2 can quickly collect large amounts of wastewater, preventing spillage outside the device. After a period of settling, the larger sludge impurities in the wastewater enter the treatment tank 1 and settle to the bottom. The agitator 4 stirs the wastewater, improving its flowability and thus increasing sludge settling efficiency. The treatment tank 1 includes a first guide plate 10, fixedly connected to the inner top wall of the treatment tank 1, which guides the wastewater and increases its impact force. The impact filter plate 12 is slidably connected to the inclined surface of the first guide plate 10, which performs preliminary filtration on the wastewater just entering the treatment tank 1. A second guide plate 11 is fixedly connected to the inner top wall of the treatment tank 1, and is used to impact the filter plate 12. To limit movement, the treatment box 1 also includes a support plate 13, which is fixedly connected to the right end of the guide plate 10. An elastic telescopic rod 14 is fixedly connected to the left side of the support plate 13, and a positioning frame 15 is fixedly connected to the free end of the elastic telescopic rod 14. The positioning frame 15 is used to fix the impact filter plate 12. An L-shaped limiting plate 16 is fixedly connected to the right side of the impact filter plate 12, and is used for quick installation and removal of the impact filter plate 12. A handle 17 is fixedly connected to the right side of the impact filter plate 12, and is used to assist in the installation and removal of the impact filter plate 12. A cam 18 is fixedly connected to the right end of the main shaft 3, and a sliding shaft is fixedly connected to the right side of the cam 18. A partition plate 19 is fixedly connected to the inner surface of the treatment box 1. The main shaft 3 and the inner surface of the support base 5 are rotatably connected. The top of the water pipe 7 is fixedly connected to the inner surface of the partition 19. The support plate 13 is fixedly connected to the right end of the guide plate 11. The left side of the cam 18 abuts against the right side of the support seat 5. The right side of the impact filter plate 12 abuts against the left side of the positioning frame 15. The L-shaped limiting plate 16 is engaged with the inner surface of the positioning frame 15. The impact filter plate 12 is slidably connected to the inner wall of the treatment box 1. A box cover is provided on the top front side of the treatment box 1. A motor is provided on the left end of the main shaft 3. When sewage comes into contact with the impact filter plate 12, large particles of impurities are separated from the sewage and fall onto the impact filter plate 12, thus performing preliminary filtration of the sewage. When the impact filter plate 12 vibrates, it shakes off the impurities stuck in the gaps to prevent them from clogging. The impact filter plate 12 can be pulled out of the treatment box 1 for easy cleaning, thereby improving the sewage filtration efficiency.The impact filter plate 12 is inserted into the positioning frame 15 via the L-shaped limiting plate 16 without affecting the movement of the impact filter plate 12, thus improving the convenience of the device.

[0023] Working principle: Wastewater is poured into the feed hopper 2 and flows into the treatment tank 1. The feed hopper 2 can quickly collect a large amount of wastewater, preventing it from spilling outside the device. After a period of settling, the larger sludge impurities in the treatment tank 1 settle to the bottom. The motor is started, driving the main shaft 3 to rotate, which in turn drives the agitator 4 to rotate. The agitator 4 agitates the wastewater, improving its flowability and thus increasing the sludge settling efficiency. When the wastewater enters the treatment tank 1, it comes into contact with the guide plate 10 and flows along the guide plate 10 towards the filter plate 12. The wastewater is obstructed by the filter plate 12, generating an impact force. The impact filter plate 12 is compressed, squeezing the positioning frame 15 and the elastic telescopic rod 14, causing the elastic telescopic rod 14 to... 4 retracts towards the support plate 13. When the impact force of the sewage decreases, the elastic resetting action of the elastic telescopic rod 14 drives the positioning frame 15 and the impact filter plate 12 to reset and thus generate vibration. When the sewage comes into contact with the impact filter plate 12, large particles of impurities are separated from the sewage and fall onto the impact filter plate 12, thus performing preliminary filtration of the sewage. When the impact filter plate 12 vibrates, it shakes off the impurities stuck in the gaps to prevent them from clogging. After the sewage in the treatment tank 1 is emptied, the front cover of the treatment tank 1 is opened. At this time, the handle 17 is held, and the impact filter plate 12 is pulled out of the treatment tank 1 through the handle 17 for easy cleaning, thereby improving the sewage filtration efficiency. The impact filter plate 12 is inserted into the positioning frame 15 through the L-shaped limiting plate 16 without affecting the movement of the impact filter plate 12, thus improving the convenience of the device.

[0024] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the filter press device 8 includes a drain pipe 81, which is fixedly connected to the right side of the treatment tank 1. The drain pipe 81 is used to discharge wastewater after filtration and phosphorus removal. A lifting plate 82 is slidably connected to the inner wall of the treatment tank 1. A convex shaft 83 is fixedly connected to the side of the lifting plate 82 away from the inner wall of the treatment tank 1. A rotating rod 84 is hinged to the inner surface of the convex shaft 83. A second convex shaft 85 is fixedly connected to the circumferential surface of the rotating rod 84. A tilting filter plate 86 is fixedly connected to the end of the second convex shaft 85 away from the lifting plate 82. The tilting filter plate 86 is used to filter the wastewater. In the filter press filtration process, when the tilting filter plate 86 moves downward, it causes the remaining sludge in the wastewater to settle to the bottom of the treatment tank 1, while the wastewater permeates above the tilting filter plate 86, thereby improving the wastewater sedimentation effect. The settled wastewater can be discharged from the treatment tank 1 through the drain pipe 81. The filter press device 8 also includes a chute frame 87, which is slidably connected to the left side of the partition plate 19. A lifting frame 88 is fixedly connected to the upper surface of the chute frame 87. A protective shell 89 is fixedly connected to the upper surface of the treatment tank 1. A connecting frame 810 is fixedly connected to the bottom right side of the lifting frame 88. A toothed rod 812 is fixedly connected to the lower surface of the connecting frame 810. Gear 811 is fixedly connected to both ends of the circumferential surface of rotating rod 84. Pressure rod 813 is fixedly connected to the side of rack 812 near the inner wall of processing box 1. Pressure rod 813 is used to drive lifting plate 82 and tilting filter plate 86 to lift synchronously. The inner surface of sliding frame 87 is slidably connected to the circumferential surface of cam 18 sliding shaft. The left side of sliding frame 87 abuts against the right side of cam 18. The left end of lifting plate 82 is slidably connected to the right side of partition plate 19. A spring is provided between the lower surface of lifting plate 82 and the bottom surface of inner wall of processing box 1. Lifting frame 88 slides through the inner wall of processing box 1 and extends out of the top surface of processing box 1. Connecting frame 810 The device is slidably connected to the right side of the inner wall of the treatment tank 1, and the connecting frame 810 is slidably connected to the right side of the partition plate 19. The lower surface of the pressure rod 813 abuts against the upper surface of the lifting plate 82. The toothed rod 812 and the gear 811 mesh with each other. The pressure rod 813 drives the lifting plate 82 and the tilting filter plate 86 to move downward and filter the sewage. When the toothed rod 812 moves upward, it drives the gear 811 to rotate in the opposite direction, thereby causing the tilting filter plate 86 to tilt and reset. At this time, when the sewage enters the right side of the partition plate 19, the sludge inside will not be blocked above the partition plate 19. Moreover, the device operates stably and conveniently and can effectively improve the filtration efficiency.

[0025] Working principle: Pump 6 is started, and the water pump 6 inputs the pre-sedimented wastewater into the right side of partition 19 through water pipe 7. At this time, cam 85 rotates along the axis of rotating rod 84, driving the rotating filter plate 86 to rotate, thus merging the two rotating filter plates 86. Lifting plate 82 moves downwards, driving cam 83 downwards. Cam 83, in turn, drives the rotating filter plate 86 downwards through rotating rod 84 and cam 85. As the rotating filter plate 86 moves downwards, the remaining sludge in the wastewater settles to the bottom of treatment tank 1, while the wastewater permeates above the rotating filter plate 86, thus improving the wastewater sedimentation effect. The settled wastewater can be discharged from treatment tank 1 through drain pipe 81. The rotation of main shaft 3 drives cam 18 to rotate, and cam 18 drives sliding frame 87 to move up and down through sliding shaft. Sliding frame 87 then drives lifting frame 88 to move up and down between treatment tank 1 and protective shell 89. The sliding mechanism, with the lifting frame 88 driving the connecting frame 810 and the rack 812 to move up and down reciprocally, causes the rack 812 to mesh with the gear 811 and rotate. The gear 811 then drives the rotating rod 84 to rotate, which in turn drives the cam shaft 85 and the flip filter plate 86 to flip. When the pressure rod 813 contacts the lifting plate 82, the gear 811 stops rotating, and the two flip filter plates 86 merge together. The lifting frame 88 continues to drive the connecting frame 810 and the rack 812 to continue to descend. The rack 812, through the pressure rod 813, drives the lifting plate 82 and the flip filter plate 86 to move downward and filter the wastewater. When the rack 812 moves upward, it drives the gear 811 to rotate in the opposite direction, causing the flip filter plate 86 to flip and reset. At this time, when the wastewater enters the right side of the partition 19, the sludge inside will not be blocked above the partition 19. The device operates stably and conveniently, and can effectively improve the filter pressing efficiency.

[0027] Working principle: When the connecting frame 810 moves up and down, it drives the connecting shaft 91 to move up and down. The connecting shaft 91 drives the sleeve shaft 92 to move up and down, and the sleeve shaft 92 drives the rotating pipe 94 and the nozzle 95 to move up and down. At this time, the agent is transported into the treatment tank 1 through the conveying pipe 93 and mixed with the sewage, thereby neutralizing and removing the phosphorus in the sewage. After neutralization, the water is discharged from the drain pipe 81, and the remaining sludge at the bottom of the treatment tank 1 can be discharged from the discharge pipe 96, thus completing the treatment of phosphorus-containing sewage. The connecting shaft 91 on the right side of the connecting frame 810 is... During the reciprocating motion, the rotating shaft 97 moves up and down, which in turn drives the gear 98 to move up and down. During the movement, the gear 98 meshes with the rack 99, causing it to rotate. The rotation of the gear 98 drives the rotating shaft 97 to rotate, which in turn drives the rotating tube 94 to rotate. The rotating tube 94 then drives the nozzle 95 to rotate circumferentially, thereby spraying the agent into the wastewater. This improves the contact efficiency between the agent and the wastewater, thereby improving the mixing efficiency and uniformity, and enhancing the neutralization effect of the device.
