Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a device for recycling and intelligent reuse of wastewater from polyaluminum chloride production. Background Technology

[0002] The core objective of treating wastewater from polyaluminum chloride (PAC) production is to remove high concentrations of suspended solids, aluminum ions, and trace amounts of heavy metals. A three-stage process—pretreatment, main treatment, and advanced treatment—is typically employed to ensure effluent meets standards. During wastewater treatment, different agents, such as flocculants, acidic solutions, and alkaline solutions, are usually added at different steps. However, because the wastewater flows continuously and the flow rate may vary, implementing a continuous flow treatment process often makes it difficult to control the amount of agents added. This can lead to over-dosing and waste, or under-dosing and reduced treatment effectiveness.

[0003] Therefore, the present invention provides a device for recycling and intelligent reuse of wastewater from polyaluminum chloride production. Summary of the Invention

This invention involves multiple treatment tanks working in cyclical cooperation, enabling continuous wastewater treatment and improving efficiency. A recovery structure can collect wastewater flowing out during the rotation gap between two treatment tanks, ensuring effective wastewater recycling. During chemical dosing, the dosing structure can control the dosage based on the wastewater flow rate, and the discharge structure can monitor the wastewater volume, allowing manual control of subsequent chemical additions. This makes the device more flexible, ensuring effective wastewater treatment and reducing chemical waste. Treated wastewater can be reintroduced into the treatment tanks for multiple treatments, further improving the treatment effect, and the treated water and residue can be recycled.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Please see Figures 1 to 10 This invention provides a technical solution: a device for recycling and intelligent reuse of wastewater from polyaluminum chloride production, comprising a base 1, on which a support structure and a rotating structure are mounted, and a drive structure is mounted on the lower side of the base 1. The drive structure is connected to the rotating structure. A wastewater treatment structure is mounted on the rotating structure. A dosing structure and a recovery structure are mounted on the support structure. A reflux structure is installed between the recovery structure and the wastewater treatment structure. The recovery structure corresponds to the wastewater treatment structure. A filtration structure is mounted on the base 1. A discharge structure is installed between the filtration structure and the wastewater treatment structure. A stirring structure is mounted on the discharge structure.

[0032] In this embodiment, the rotating structure includes a rotating frame 6, which corresponds to the supporting structure and is rotatably connected to the base 1. The driving structure includes a motor 3 fixed to the lower side of the base 1. A first gear 4 is rotatably engaged on the base 1, and a second gear 5 is fixed to the lower side of the rotating frame 6. The first gear 4 and the second gear 5 mesh with each other. The output end of the motor 3 is fixedly connected to the first gear 4. The supporting structure includes a support frame 2 fixed to the base 1, and the rotating frame 6 is rotatably connected to the support frame 2.

[0033] Specifically, when treating wastewater, multiple treatment tanks 7 work alternately and periodically to treat the wastewater. During treatment, the motor 3 is started, which drives the first gear 4 to rotate. The first gear 4 meshes with the second gear 5, causing the rotating frame 6 to rotate. This, in turn, drives the multiple treatment tanks 7 fixed on the rotating frame 6 to rotate, thus enabling the treatment tanks 7 to periodically collect water and treat wastewater. Furthermore, the support frame 2 and the base 1 provide good support for the rotating frame 6, allowing it to bear heavy forces and ensuring the stability of the treatment tanks 7 during operation. This prevents the device from becoming unstable due to excessive water collection in the treatment tanks 7.

[0034] A feed pipe 9 is fixed on the support frame 2. The dosing structure includes a medicine box 10 fixed on the support frame 2. A medicine inlet 11 is opened on one side of the medicine box 10, and a medicine outlet 24 is opened at the bottom of the medicine box 10. The medicine outlet 24 is connected to the feed pipe 9. A flow regulating structure is installed in the medicine outlet 24. The flow regulating structure includes a push plate 12, which is located in the feed pipe 9. A rotating shaft 13 is rotatably fitted in the medicine outlet 24. The rotating shaft 13 is fixedly connected to the push plate 12. A rotating groove 14 is opened in the medicine box 10. The rotating groove 14 corresponds to the medicine outlet 24. The rotating groove 14 is rotatably connected to the rotating shaft 13. A first sliding groove 16 is opened in the rotating shaft 13. A positioning rod 15 is slidably fitted in the first sliding groove 16. The positioning rod 15 is a long strip structure.

[0035] Specifically, when wastewater is discharged through the feed pipe 9, the flow of wastewater drives the push plate 12 to move, causing the push plate 12 to rotate via the rotating shaft 13. The elliptical structure of the rotating shaft 13 creates a gap between it and the inlet 11. As the rotation amplitude of the push plate 12 varies with different flow rates, the size of the gap between the rotating shaft 13 and the inlet 11 also varies. This allows for control of the amount of chemical added based on the water flow rate, thus controlling the dosage ratio and preventing waste due to excessive dosage or poor wastewater treatment due to insufficient dosage. Furthermore, the water flow rate can be automatically controlled by the water flow size, and the angle of the rotating shaft 13 can be fixed by the sliding positioning rod 15, enabling active control of the water flow rate. This makes the device more flexible to use and ensures effective wastewater treatment.

[0036] A push tube 18 is installed between one end of the positioning rod 15 and the wall of the rotating groove 14. The other end of the positioning rod 15 has a tapered structure and a friction texture on its surface. A limit ring 17 is fixed inside the rotating groove 14, and the limit ring 17 corresponds to the positioning rod 15. A locking structure is installed inside the push tube 18. The push tube 18 includes a first tube body 19 and a second tube body 20. The first tube body 19 is rotatably connected to the rotating groove 14, and the second tube body 20 is fixedly connected to the positioning rod 15. The first tube body 19 and the second tube body 20 are slidably connected. A first electromagnet 23 is fixed inside the rotating groove 14, and the first electromagnet 23 corresponds to the positioning rod 15. A second sliding groove 22 is opened inside the first tube body 19, and the second sliding groove 22 corresponds to the second tube body 20. Multiple first springs 21 are fixed between the wall of the second sliding groove 22 and the second tube body 20.

[0037] Specifically, when it is necessary to fix the flow rate of the added medicine, the first electromagnet 23 is energized, causing it to attract the positioning rod 15. This causes the positioning rod 15 to slide, compressing the second tube 20 into the second sliding groove 22. The first spring 21 is compressed, and the conical end of the positioning rod 15 contacts the limiting ring 17, generating significant friction. This friction limits the positioning rod 15. The elongated structure of the positioning rod 15 can limit the rotation shaft 13, preventing it from rotating. This fixes the gap between the rotation shaft 13 and the medicine outlet 24, allowing for active control of the added medicine amount. This makes the device more flexible to use and expands its applicability.

[0038] The recycling structure includes a recycling box 25 fixed on a support frame 2, a recycling pipe 26 fixed inside the support frame 2, and multiple first through holes 27 at the end of the recycling pipe 26, which are connected to the recycling box 25. The wastewater treatment structure includes multiple treatment tanks 7 fixed on a rotating frame 6, a recycling frame 40 fixed between two adjacent treatment tanks 7, the recycling frame 40 being rotatably connected to the recycling box 25, a recycling trough on the recycling frame 40, which is connected to the recycling box 25. The reflux structure includes a first water pump, the inlet of the first water pump being connected to the recycling box 25, and the outlet of the first water pump being connected to one of the treatment tanks 7.

[0039] Specifically, when the rotating frame 6 drives the treatment tank 7 to rotate, the wastewater flows through the feed pipe 9 to the gap between the two treatment tanks 7. At this time, it can enter the recycling tank 25 through the recycling trough, and then flow out from the first through hole 27 into the recycling pipe 26. The first water pump is started, and the water is pumped and sent into the treatment tank 7 for treatment, thereby ensuring the treatment effect of the wastewater and reducing the waste of wastewater.

[0040] A stirring rod 8 is rotatably fitted inside the recycling bin 25. The filtration structure includes a filter box 28 fixed to the base 1. One end of the stirring rod 8 is located inside the filter box 28, and multiple fan blades 37 are fixed to the end of the stirring rod 8 inside the filter box 28. A filter plate 29 is fixed inside the filter box 28. A second water pump is fixed to the side of the filter box 28. The inlet of the second water pump is connected to the filter box 28 and is located below the filter plate 29. The outlet of the second water pump is connected to the filter box 28 and the processing tank 7, and the position of the connection with the filter box 28 is located above the filter plate 29 and on one side of the fan blades 37. An electric three-way valve is installed at the outlet of the second water pump. A drain pipe 30 and a slag discharge pipe 31 are fixed to the bottom of the filter box 28. Both the drain pipe 30 and the slag discharge pipe 31 are connected to the filter box 28. The filter is connected to the filter plate 29. The top of the drain pipe 30 is located on the lower side of the filter plate 29, and the top of the slag discharge pipe 31 is located on one side of the filter plate 29. An electric valve 32 is installed in the slag discharge pipe 31. Multiple partitions 38 are fixed in the filter box 28. The discharge structure includes a groove 33 opened in the stirring rod 8. The groove 33 is connected to the filter box 28. Multiple second through holes 34 are opened on the side of the groove 33. The second through holes 34 are connected to the processing tank 7. A sliding rod 35 is slidably fitted in the groove 33. Multiple second springs 36 are fixed between the sliding rod 35 and the groove wall of the groove 33. The bottom of the sliding rod 35 is a conical structure. Multiple second electromagnets are fixed in the filter plate 29. The second electromagnets correspond to the sliding rod 35. A distance sensor 39 is installed in the groove 33.

[0041] Specifically, when wastewater needs treatment, the wastewater can be initially mixed with the reagent in the feed pipe 9. After the wastewater enters the treatment tank 7, the second water pump can be started to draw water from the lower side of the filter plate 29 in the filter box 28 and send it to the upper side of the filter plate 29. This not only impacts the fan blades 37, causing them to drive the stirring rod 8 to rotate and stir, but also ensures that the reagent and wastewater are thoroughly mixed, thus ensuring the effectiveness of wastewater treatment. Secondly, the water sprayed by the second water pump can wash the surface of the filter plate 29, thus flushing the solid residue filtered off the surface of the filter plate 29 to the electric valve 32. When the electric valve 32 is opened, the solid impurities can be sent out through the slag discharge pipe 31, which will fall off naturally, allowing for the recovery of the impurities. Alternatively, the wastewater can be directly sent back to the treatment tank 7 by the second water pump for further treatment, thus ensuring the effectiveness of wastewater treatment. When the wastewater and reagent... After thorough mixing and reaction, the second electromagnet is energized, causing it to attract the sliding rod 35. This causes the sliding rod 35 to slide downwards, creating a gap between it and the groove 33. Wastewater can then enter the groove 33 through the second through-hole 34 and flow downwards, thus filtering the wastewater. When the sliding rod 35 blocks the groove 33, the wastewater entering the treatment tank 7 generates water pressure, which pushes the sliding rod 35 downwards a certain distance. At this point, the second spring 36 is compressed and pushed upwards, preventing the sliding rod 35 from sliding too far downwards and causing leakage. The distance the sliding rod 35 slides can be monitored by the distance sensor 39, allowing the determination of the wastewater volume in the treatment tank 7. Based on this volume, subsequent reagents can be manually added in precise quantities, ensuring effective wastewater treatment, reducing reagent waste, and improving the flexibility of the device.

[0042] Workflow: When treating wastewater, multiple treatment tanks 7 work alternately and periodically to treat the wastewater. During treatment, the motor 3 is started, which drives the first gear 4 to rotate. The first gear 4 meshes with the second gear 5, causing the rotating frame 6 to rotate. This, in turn, drives the multiple treatment tanks 7 fixed on the rotating frame 6 to rotate, thus enabling the treatment tanks 7 to periodically collect water and treat wastewater. When wastewater is discharged through the feed pipe 9, the flow of wastewater drives the push plate 12 to move, causing the push plate 12 to rotate via the rotating shaft 13. At this time, a gap is created between the elliptical structure of the rotating shaft 13 and the inlet 11, and as the push plate 12 is moved by different flows... The size of the gap between the rotating shaft 13 and the inlet 11 varies depending on the rotation amplitude of the flow rate, allowing control of the dosage and ratio based on the water flow. When a fixed dosage flow rate is required, the first electromagnet 23 is energized, attracting the positioning rod 15 and causing it to slide. This compresses the second tube 20 into the second sliding groove 22, compressing the first spring 21. The conical end of the positioning rod 15 contacts the limiting ring 17, generating significant friction. This friction limits the positioning rod 15. The elongated structure of the positioning rod 15 also limits the rotation of the rotating shaft 13, preventing it from rotating and thus fixing it in place. The size of the gap between the rotating shaft 13 and the outlet 24 allows for active control of the dosage. When wastewater needs treatment, the wastewater can be initially mixed with the agent in the feed pipe 9. After the wastewater enters the treatment tank 7, the second water pump can be started to draw water from the lower side of the filter plate 29 in the filter box 28 and send it to the upper side of the filter plate 29. This not only impacts the fan blades 37, causing them to drive the stirring rod 8 to rotate and stir, but also ensures that the agent and wastewater are thoroughly mixed, thus guaranteeing the effectiveness of wastewater treatment. Furthermore, the water sprayed by the second water pump can rinse the surface of the filter plate 29, thereby filtering out the impurities on the surface of the filter plate 29. Solid residues are flushed onto the electric valve 32. When the electric valve 32 is opened, the solid impurities can be discharged through the slag discharge pipe 31. The slag discharge pipe 31 falls off naturally, allowing the impurities to be recovered. Alternatively, the wastewater can be directly pumped back into the treatment tank 7 for further treatment, ensuring the treatment effect. After the wastewater and the reagent are fully mixed and reacted, the second electromagnet is energized, causing it to attract the sliding rod 35. This causes the sliding rod 35 to slide downwards, creating a gap between the sliding rod 35 and the groove 33. The wastewater can then enter the groove 33 through the second through hole 34 and flow downwards, thus achieving wastewater filtration.Furthermore, when the sliding rod 35 blocks the groove 33, the wastewater entering the treatment tank 7 generates water pressure, which pushes the sliding rod 35 downwards. The sliding rod 35 slides downwards a certain distance, at which point the second spring 36 is compressed and pushed upwards, preventing the sliding rod 35 from sliding too far downwards and thus preventing leakage. The distance the sliding rod 35 slides can be monitored by the distance sensor 39, allowing the volume of wastewater in the treatment tank 7 to be estimated. Based on this volume, subsequent reagents can be manually added in precise quantities.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
