[0031] This disclosure aims to address the problem that existing rare earth wastewater treatment devices typically involve adding flocculants to the wastewater, followed by filtration after flocculation. However, during prolonged filtration, the accumulation of flocculants leads to filter clogging, resulting in reduced treatment efficiency and quality. Therefore, this disclosure proposes a rare earth wastewater treatment device. By incorporating labeling and fixing devices, and a treatment mechanism, this device achieves efficient mixing and flocculation of wastewater and chemicals, significantly improving treatment efficiency. A spraying mechanism ensures uniform spraying of chemicals, guaranteeing consistent and stable flocculation effects, thus enhancing wastewater treatment. A replacement and cleaning mechanism enables automatic replacement and efficient cleaning of the filter discs without manual intervention, greatly improving efficiency and reducing maintenance costs and the risk of operational errors. A flipping component precisely controls the flipping of the filter discs, further enhancing cleaning effectiveness. A well-designed sealing mechanism effectively prevents wastewater leakage, ensuring treatment quality while extending equipment lifespan and reducing maintenance costs.

[0032] like Figures 1 to 10 As shown, a rare earth wastewater treatment device includes a tower body 1, a feed inlet 2, a treatment mechanism 3, a spraying mechanism 4, and a replacement and cleaning mechanism 5. The tower body 1 is fixed and has the feed inlet 2. The treatment mechanism 3 is installed inside the tower body 1 and is used to filter the wastewater. The spraying mechanism 4 is installed above the treatment mechanism 3 and is used to spray chemical agents into the wastewater, thereby cooperating with the treatment mechanism 3 to complete the wastewater treatment. The replacement and cleaning mechanism 5 is installed on one side of the tower body 1 and is used to replace the filter screen and clean the replaced treatment mechanism 3.

[0033] By setting up a treatment device and designing treatment mechanism 3, efficient mixing and flocculation reaction of wastewater and chemicals are achieved, significantly improving treatment efficiency. Spraying mechanism 4 can evenly spray chemicals, ensuring the consistency and stability of flocculation effect, thereby enhancing wastewater treatment effect. Replacement and cleaning mechanism 5 realizes automatic replacement and efficient cleaning of filter disc 35. The whole process does not require manual intervention, greatly improving work efficiency and reducing manual maintenance costs and the risk of operational errors. Tilting component 58 further improves the cleaning effect by precisely controlling the rotation of filter disc 35. The sealing mechanism is reasonably designed to effectively prevent wastewater leakage, ensure treatment effect, extend equipment service life, and reduce maintenance costs.

[0034] like Figures 1 to 6As shown, the treatment mechanism 3 includes a treatment chamber 31, a stirring motor 32, a stirring shaft 33, stirring rods 34, and a filter disc 35. The treatment chamber 31 is located inside the tower body 1 and is used to treat wastewater. The stirring motor 32 is installed above the tower body 1 and is used to drive the stirring shaft 33 to rotate. The stirring shaft 33 is installed at the output end of the stirring motor 32 and is used to drive the stirring rods 34 to rotate. The stirring rods 34 are arranged in an array on the stirring shaft 33 and are used to mix the wastewater and chemical agents evenly to complete flocculation. A filter disc 35 is provided at the bottom of the treatment chamber 31 and is used to filter the flocculated sediment.

[0035] During operation, the wastewater to be treated enters the treatment chamber 31 through the feed inlet 2. At this time, the spraying mechanism 4 starts to sprinkle the agent into the treatment chamber 31. At this time, the stirring motor 32 drives the stirring shaft 33 to rotate. The rotating stirring shaft 33 drives the stirring rod 34 to rotate. The rotating stirring rod 34 makes the agent and wastewater mix quickly. After mixing, the mixture is filtered through the filter plate 35.

[0036] Through the design of the above-mentioned treatment mechanism 3, efficient mixing and full flocculation of wastewater and reagents are achieved, which greatly improves the treatment efficiency; at the same time, the filter plate 35 can effectively intercept flocculation sedimentation to ensure that the effluent water quality meets the standards; the overall structure is easy to operate and maintain, which can significantly reduce the treatment cost and effectively reduce the pollution risk of rare earth wastewater to the environment.

[0037] like Figures 1 to 6 As shown, the spraying mechanism 4 includes a spraying motor 41, a water storage tank 42, a water supply pipe 43, a water distribution pipe 44, and spray nozzles 45. The spraying motor 41 is installed on one side of the tower body 1 and is used to draw the agent from the water storage tank 42. The water storage tank 42 is fixed to one side of the bottom of the tower body 1 and is used to store the agent. The water supply pipe 43 is installed on the water storage tank 42 and is used to transport the agent to the water distribution pipe 44. The spraying motor 41 is connected to the water supply pipe 43. The water distribution pipe 44 is installed at the end of the water supply pipe 43 and is used to transport the agent to the spray nozzles 45. The water distribution pipe 44 is located inside the tower body 1, and the spray nozzles 45 are arranged in an array on the water distribution pipe 44. The spray nozzles 45 are used to spray the agent into the wastewater to complete flocculation.

[0038] During operation, the spraying motor 41 is started, which drives the agent to move from the water storage tank 42 to the water delivery pipe 43. The water delivery pipe 43 carries the agent to the water distribution pipe 44, which then delivers the agent to the spray nozzle 45. The spray nozzle 45 sprays the agent evenly onto the wastewater for flocculation and sedimentation.

[0039] Through the coordinated action of the spray motor 41, water storage tank 42, water delivery pipe 43, water distribution pipe 44, and spray nozzle 45, the agent can be evenly sprayed into the wastewater to achieve efficient flocculation and sedimentation. This mechanism ensures full contact between the agent and the wastewater, improving the consistency and stability of the flocculation effect, thereby enhancing the wastewater treatment effect.

[0040] like Figures 1 to 9 As shown, the replacement cleaning mechanism 5 includes a replacement chamber 51, a support column 52, a replacement bracket 53, a replacement motor 54, a water pump 55, a water pump 56, a high-pressure nozzle 57, and a tilting assembly 58. The replacement chamber 51 is located inside the tower body 1 and on the left side of the processing chamber 31, and is used to install the replacement cleaning mechanism 5. A support column 52 is installed between the replacement chamber 51 and the processing chamber 31, and is used to fix the replacement bracket 53. The replacement bracket 53 is installed at the bottom of the support column 52, and is used to rotate the filter disc 35. The filter disc 35 is installed on the replacement bracket 53. A replacement motor 54 is installed at the bottom of the replacement bracket 53, which drives the replacement bracket 53 to rotate. A water suction pipe 55 is installed at the bottom of the processing chamber 31, which is used to extract the filtered water from the processing chamber 31. A water pump 56 is installed on the water suction pipe 55, which works with the water suction pipe 55 to extract the filtered wastewater. A high-pressure nozzle 57 is installed at the other end of the water suction pipe 55, which is used to flush water onto the filter disc 35. A flipping assembly 58 is installed on the replacement bracket 53. The flipping assembly 58 is used to rotate the rotating disc, thereby working with the high-pressure nozzle 57 to clean the rotating disc.

[0041] During operation, the replacement motor 54 drives the replacement bracket 53 to rotate around the support column 52, which in turn causes the replacement bracket 53 to drive the rotating disk to rotate from the processing chamber 31 into the replacement chamber 51. At the same time, the flipping component 58 drives the filter disk 35 to flip. At this time, the water pump 56 starts, and the water pump 56 drives the filtered wastewater to flow through the water pipe 55 to the high-pressure nozzle 57 for flushing, thereby cleaning the filter disk 35 for the next replacement.

[0042] By incorporating a replacement chamber 51, support column 52, replacement bracket 53, replacement motor 54, water pump 55, water pump 56, high-pressure nozzle 57, and tilting assembly 58, the filter disc 35 can be automatically replaced and efficiently cleaned. The entire process requires no manual intervention, achieving a high degree of automation, effectively improving work efficiency, reducing manual maintenance costs, and avoiding risks caused by human error. Simultaneously, this mechanism can promptly remove impurities from the filter disc 35, maintaining its cleanliness and efficient filtration performance, extending equipment lifespan, and further improving the rare earth wastewater treatment effect and equipment operational stability.

[0043] like Figures 1 to 9As shown, the flipping assembly 58 includes a flipping motor 581, a rotating rod 582, an infrared emitter 583, and a sensing plate 584. The flipping motor 581 is mounted on the replacement bracket 53 and drives the rotating rod 582 to rotate. The output end of the replacement motor 54 is equipped with the rotating rod 582, which rotates to drive the filter disc 35 to rotate. The infrared emitter 583 is installed in the processing chamber 31 and the replacement chamber 51 and emits infrared signals. The sensing plate 584 is mounted on the replacement bracket 53 and senses the infrared signals to cooperate with the rotating rod 582 to drive the filter disc 35 to rotate.

[0044] During operation, the replacement bracket 53 drives the filter disc 35 to rotate. After rotation, the sensor 584 can no longer detect the infrared emitter 583. This means that the filter disc 35 is separated from the processing chamber 31 and the replacement chamber 51. After 5 seconds, the rotating bracket is perpendicular to the straight line formed by the center of the processing chamber 31 and the replacement chamber 51. The rotating motor 581 that rotates out of the processing chamber 31 starts. The started rotating motor 581 drives the rotating rod 582 to rotate. The rotating rod 582 drives the filter disc 35 to rotate. Then the replacement bracket 53 drives the rotated filter disc 35 to rotate into the replacement chamber 51 for cleaning.

[0045] By incorporating a flip motor 581, a rotating rod 582, an infrared transmitter 583, and a sensor 584, precise flipping control of the filter disc 35 is achieved. In conjunction with the replacement bracket 53, this ensures the filter disc 35 is thoroughly rinsed during cleaning, improving cleaning efficiency. Simultaneously, this component utilizes infrared sensing technology to automate operation, reducing manual intervention, lowering the risk of operational errors, and enhancing equipment reliability and efficiency.

[0046] like Figures 7 to 9 As shown, a fixing sleeve 6 is installed on the outer side of the filter disc 35, which is used to fix the filter disc 35. A circular groove 61 is symmetrically formed inside the fixing sleeve 6, which is used to place the sealing plate 64. A fixing groove 62 is installed at the bottom of the circular groove 61 to fix the return spring 63. The return spring 63 is installed inside the fixing groove 62 and is used to reset the sealing plate 64. The sealing plate 64 is installed on the return spring 63. Both the processing chamber 31 and the replacement chamber 51 have sealing grooves 7 that fit with the sealing plate 64. The sealing plate 64 cooperates with the sealing groove 7 to seal the filter disc 35. A ring-shaped high-power electromagnet 71 is installed inside the sealing groove 7. The high-power electromagnet is used to attract the sealing disc and complete the sealing process when energized.

[0047] During operation, the replacement bracket 53 moves the filter disc 35 to below the replacement chamber 51 and the treatment chamber 31. At this time, the powerful electromagnet is activated and attracts the sealing plate 64 into the sealing groove 7, thus sealing the filter disc 35. When rotation is required, the powerful electromagnet is de-energized, and the sealing plate 64 is reset under the pull of the return spring 63. The filter disc 35 is then replaced by rotating the replacement bracket 53.

[0048] Through the coordinated action of the fixed sleeve 6, annular groove 61, fixed groove 62, return spring 63, sealing plate 64, sealing groove 7, and annular high-power electromagnet 71, the filter disc 35 achieves automatic sealing and reset, which is convenient to operate and has a reliable sealing effect. When the high-power electromagnet is energized, it can attract the sealing plate 64 to complete the seal. When the power is off, the return spring 63 pulls the sealing plate 64 to reset, which facilitates the replacement of the filter disc 35 and effectively improves work efficiency.

[0049] like Figure 2 and Figure 4 As shown, two collection boxes 8 are symmetrically installed inside the tower body 1 for collection. The collection boxes 8 are located on the front and rear sides inside the tower body 1. The collection boxes 8 are used to collect the flocs that fall off from the filter disc 35 after being flipped, ensuring that the flocs can be collected efficiently and centrally, avoiding secondary pollution, improving the wastewater treatment effect, optimizing the internal cleanliness of the device, reducing maintenance requirements, and enhancing the overall operating efficiency and environmental performance.

[0050] The overall working process is as follows: The wastewater to be treated enters the treatment chamber 31 through the feed inlet 2. At this time, the spray motor 41 is started. The start of the spray motor 41 drives the agent to move from the water storage tank 42 to the water delivery pipe 43. The water delivery pipe 43 carries the agent to the water distribution pipe 44. The water distribution pipe 44 delivers the agent to the spray nozzle 45. The spray nozzle 45 sprays the agent evenly on the wastewater for flocculation and sedimentation. At this time, the stirring motor 32 drives the stirring shaft 33 to rotate. The rotating stirring shaft 33 drives the stirring rod 34 to rotate. The rotating stirring rod 34 makes the agent and wastewater mix quickly. After mixing, the mixture is filtered through the filter plate 35.

[0051] After filtration is completed, the replacement motor 54 drives the replacement bracket 53 to rotate around the support column 52, which in turn causes the replacement bracket 53 to drive the rotating disk to rotate from the treatment chamber 31 into the replacement chamber 51. At the same time, the flipping component 58 drives the filter disk 35 to flip. At this time, the water pump 56 starts, and the water pump 56 drives the filtered wastewater to flow through the water pumping pipe 55 to the high-pressure nozzle 57 for flushing, thereby cleaning the filter disk 35 for the next replacement.
