Description

Technical Field

[0001] This invention relates to the field of phosphogypsum production technology, and in particular to an online lime mixing system and method for water-washed phosphogypsum. Background Technology

[0002] In existing technologies, phosphogypsum is a byproduct of wet-process phosphoric acid production. It mainly consists of calcium sulfate dihydrate (CaSO4·2H2O) and contains acid-insoluble matter, undecomposed phosphate rock and its impurities, unwashed water-soluble P2O5, and small amounts of CaHPO4 replacing CaSO4·2H2O, as well as small amounts of fluorosilicates and other waste residues. The amount of phosphogypsum depends primarily on the CaO content and acid-insoluble matter content in the phosphate rock. Approximately 4.5–5.5 tons of phosphogypsum (dry basis) are generated for every ton of P2O5 produced.

[0003] China's annual phosphogypsum emissions are approximately 80 million tons, with a total existing stockpile exceeding 600 million tons. Stockpiling phosphogypsum not only occupies a large amount of land but also causes environmental pollution. Therefore, constructing a harmless treatment and comprehensive utilization project for phosphogypsum is a necessary means to achieve the sustainable development of the company's phosphate chemical industry.

[0004] In the existing technology, when phosphogypsum is washed with lime water, there is a lack of control over the quicklime. At this time, the quicklime is prone to clumping, which affects the mixing, and it is not convenient to dehydrate after the reaction is allowed to stand.

[0005] Therefore, this invention proposes an online lime mixing system and method for water-washed phosphogypsum to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this application is to provide an online lime mixing system and method for water-washed phosphogypsum to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this application provides the following technical solution: an online lime mixing system for washed phosphogypsum, comprising a hollow base, and the online lime mixing system further comprising:

[0008] A bracket, which is fixedly connected inside the base;

[0009] A mixing chamber, which is fixedly connected to the right side of the bracket;

[0010] A reaction chamber, which is fixedly connected inside the base;

[0011] A lime box, which is fixedly connected to the top of the support frame;

[0012] The bracket is fixedly connected to the front side of the mixing tank;

[0013] The support frame is equipped with a control mechanism and an auxiliary mechanism.

[0014] With the above structure, the online lime mixing system of the present invention forms a highly integrated processing flow through a carefully designed combination of diversified components, including key units such as mixing tank, reaction tank and lime tank. This system has significant advantages in automation, ensuring precise mixing between washed phosphogypsum and quicklime. This design not only optimizes the contact and reaction conditions of materials, but also minimizes human intervention, improving the precision and efficiency of production. In particular, under the precise control of fluid dynamics, the mixing process achieves high-efficiency output, ensuring the consistency of each batch of materials, thereby greatly improving the stability of the overall production line and the reliability of long-term operation.

[0015] Preferably, the control mechanism includes two guide columns, a movable belt, an adjusting plate, a rotating plate, and an adjusting door. The two guide columns are rotatably connected to the left side of the bracket. The movable belt is sleeved on the outer wall of the two guide columns. The adjusting plate is slidably connected to the left side of the bracket, and the rear side of the adjusting plate is fixedly connected to the outer wall of the movable belt. The rotating plate is rotatably connected to the front side of the adjusting plate. The adjusting door is slidably connected inside the lime box, and the left side of the adjusting door extends to the outside of the lime box. The front side of the adjusting door is rotatably connected to the top of the rotating plate.

[0016] Furthermore, the linkage design of the guide column and the movable belt in the control mechanism, through the precise adjustment of the regulating plate, effectively controls the accurate amount of quicklime to be added. Its unique design principle allows the amount of quicklime added each time to be adjusted within a very strict range, avoiding the risk of over- or under-addition, and further reducing the clumping phenomenon of quicklime during the addition process. This ensures the mixing quality while reducing the maintenance needs of the equipment. The efficient particle size and humidity control also improves the chemical reaction efficiency of quicklime and phosphogypsum, promoting the maximum utilization of resources.

[0017] Preferably, an electric actuator is fixedly connected to the left side of the bracket, and a horizontal plate is fixedly connected to the output end of the electric actuator. The right side of the horizontal plate is slidably connected to the left side of the bracket, and the front side of the horizontal plate is fixedly connected to the outer wall of the movable belt.

[0018] Furthermore, the precise combination of the electric actuator and the cross plate can efficiently drive the moving belt to rotate, ensuring smoother and more precise control of the regulating gate. This makes the lime addition process both fast and stable, and can automatically adapt to changing operating environments. By reducing reliance on manual operation, it not only improves the operator's work efficiency but also reduces the possibility of human error, further enhancing the control precision and response speed of the entire mixing process.

[0019] Preferably, the auxiliary mechanism includes a hollow tube, a contact frame, a movable plate, a connecting rod, and a movable door. The hollow tube is fixedly connected to the front side of the mixing tank. The contact frame is slidably connected inside the hollow tube, and the bottom of the contact frame extends outside the hollow tube. The movable plate is slidably connected to the front side of the reaction tank, and the top of the movable plate is fixedly connected to the bottom of the contact frame. The connecting rod is rotatably connected to the front side of the movable plate. The movable door is slidably connected to the bottom of the reaction tank, and the front side of the movable door is rotatably connected to the bottom of the connecting rod.

[0020] Furthermore, the auxiliary mechanism optimizes the flow path of materials in the reaction chamber through the linkage between the hollow tube and the contact frame, ensuring the effective distribution and processing of materials during the reaction process, improving the separation efficiency of phosphogypsum and water, and significantly reducing possible material waste during the reaction process. This, in turn, improves the dehydration effect of the system and ensures that every step of the production process meets the expected quality standards.

[0021] Preferably, a rotating column is rotatably connected to the front side of the mixing box, and an eccentric wheel is fixedly connected to the front side of the rotating column. The eccentric wheel is in movable contact with the bottom of the contact frame, and a spring is fixedly connected to the top of the contact frame. One end of the spring is fixedly connected to the top inner wall of the hollow tube.

[0022] Furthermore, by using an eccentric wheel in conjunction with a spring, the contact frame inside the hollow tube can achieve more precise displacement control, saving energy costs and further reducing the system's operational burden.

[0023] Preferably, a pull ring is slidably connected to the top of the bracket, and a pull belt is wound around the outer wall of the rotating column, with one end of the pull belt fixedly connected to the right side of the pull ring.

[0024] Furthermore, the design of the pull ring and pull belt allows the rotating column to rotate, greatly reducing the complexity of controlling the rotating column, significantly improving the lifespan and maintainability of the equipment, and reducing maintenance costs during long-term use.

[0025] Preferably, a filter plate is fixedly connected inside the reaction chamber, and the filter plate cooperates with the movable door.

[0026] Furthermore, the addition of the filter plate significantly improves the separation efficiency of water and materials during the reaction process. The filter plate can efficiently separate excess water from the washed phosphogypsum, ensuring that the material has reached the ideal humidity standard when it enters the next processing stage. This not only improves the dehydration effect but also creates more stable operating conditions for the subsequent chemical reaction process, thereby ensuring the continuity and stability of the entire production process.

[0027] Preferably, a guide door is rotatably connected to the bottom of the mixing tank, and a motor is fixedly connected to the bottom of the bracket, with the output shaft of the motor fixedly connected to the front side of the guide door.

[0028] Furthermore, the guide gate, controlled by a motor, allows the mixture to be smoothly introduced from the mixing chamber into the reaction chamber, avoiding loss or uneven mixing caused by improper material transfer. This ensures that the flow of each batch of material is orderly and controllable, significantly improving the automation level of the production line, reducing the complexity of manual operation, and lowering the system failure rate.

[0029] Preferably, a mixer is fixedly connected to the top of the mixing chamber, and a stirring rod is provided at the bottom of the mixer, with the bottom of the stirring rod extending into the mixing chamber.

[0030] Furthermore, the mixing rod design inside the mixer fully considers the flowability and mixing effect of the materials, ensuring that quicklime and phosphogypsum can fully contact and react quickly during the mixing process, reducing energy consumption and improving productivity. The mixer can automatically adjust the mixing speed and intensity according to the different characteristics of the materials, further improving the mixing quality and ensuring the consistency and stability of each batch of materials.

[0031] This invention also proposes a method for an online lime mixing system for water-washed phosphogypsum, comprising the following steps:

[0032] S1: First, add quicklime to the lime box, and add phosphogypsum and water to the mixing box. Then, control the electric actuator to lower the horizontal plate.

[0033] S2: Then the horizontal plate can synchronously control the movable belt to rotate, the movable belt can control the adjusting plate to rise, at this time the adjusting plate can push the rotating plate to move, at this time the top of the rotating plate can push the adjusting door to move to the left;

[0034] S3: By cyclically controlling the output end of the electric actuator to move, the regulating gate can be cyclically controlled to move. At this time, the regulating gate can control the quicklime to enter the mixing box in batches, effectively preventing the quicklime from entering in large quantities and causing clumping.

[0035] S4: Then the mixer is operated by controlling the mixer, which can mix quicklime and phosphogypsum through the mixing rod;

[0036] S5: And control the motor to work. At this time, the output shaft of the motor can control the guide door to rotate. The guide door rotates and opens to form an inclined plane, which can guide the material inside the mixing box into the reaction box for static reaction.

[0037] S6: Finally, the staff pulls the ring to the left to move it. The ring can control the rotating column to rotate through the pull belt, and the rotating column can drive the eccentric wheel to rotate. At this time, the eccentric wheel can contact the bottom of the contact frame, thereby pushing the contact frame to move upward. The contact frame can pull the moving plate to rise. At this time, the moving plate can pull the connecting rod to move. At this time, the connecting rod can pull the movable door to the right through its bottom, thereby controlling the movable door to open. The material inside the reaction chamber passes through the filter plate to remove the moisture inside the phosphogypsum, ensuring a thorough dehydration effect.

[0038] In summary, the technical effects and advantages of this invention are as follows:

[0039] 1. By pre-adding quicklime to the lime box and adding phosphogypsum and water to the mixing box, the output end of the electric actuator is cyclically moved, thus achieving the effect of cyclically controlling the movement of the regulating gate. By cyclically controlling the movement of the regulating gate, quicklime is controlled to enter the mixing box in batches, effectively preventing the occurrence of clumping due to a large amount of quicklime entering.

[0040] 2. The mixer operates by mixing quicklime and phosphogypsum. In conjunction with a motor, the mixer guides the mixed material into the reaction chamber for static reaction.

[0041] 3. The door is moved by the staff pulling the pull ring, which helps to open the door. At this time, the material inside the reaction chamber passes through the filter plate to remove the water inside the phosphogypsum, ensuring a thorough dehydration effect.

[0042] This invention involves pre-adding quicklime to a lime box and simultaneously adding phosphogypsum and water to a mixing box. At this time, the electric actuator, motor, and mixer work together to control the quicklime to enter in batches, preventing clumping, and automatically controlling the mixing of phosphogypsum and quicklime. After standing, the dehydration effect is also automatically controlled. Attached Figure Description

In particular, under the precise control of fluid dynamics, the mixing process achieves high-efficiency output, ensuring the consistency of each batch of materials, thereby greatly improving the stability of the overall production line and the reliability of long-term operation.

[0062] In this embodiment, the control mechanism includes two guide columns 7, a movable belt 8, an adjusting plate 9, a rotating plate 10, and an adjusting door 4. The two guide columns 7 are rotatably connected to the left side of the support 2. The movable belt 8 is sleeved on the outer wall of the two guide columns 7.

The linkage design of the guide columns 7 and the movable belt 8 in the control mechanism, through the precise adjustment of the adjusting plate 9, effectively controls the precise amount of quicklime added. Its unique design principle allows the amount of quicklime added each time to be adjusted within a very strict range, avoiding the risk of over- or under-addition, and further reducing the clumping phenomenon of quicklime during the addition process. Thus, while ensuring the mixing quality, it reduces the maintenance requirements of the equipment.

The right side of the horizontal plate 6 is slidably connected to the left side of the support 2, and the front side of the horizontal plate 6 is fixedly connected to the outer wall of the movable belt 8.

This makes the lime addition process both fast and stable, and can automatically adapt to changing operating environments. By reducing reliance on manual operation, it not only improves the operator's work efficiency but also reduces the possibility of human error, further enhancing the control accuracy and response speed of the entire mixing process.

[0064] In this embodiment, the auxiliary mechanism includes a hollow tube 20, a contact frame 21, a movable plate 23, a connecting rod 24, and a movable door 25. The hollow tube 20 is fixedly connected to the front side of the mixing box 19. The contact frame 21 is slidably connected inside the hollow tube 20, and the bottom of the contact frame 21 extends outside the hollow tube 20.

This improves the dehydration effect of the system and ensures that every step of the production process meets the expected quality standards.

[0065] In this embodiment, a rotating column 16 is rotatably connected to the front side of the mixing box 19, and an eccentric wheel 18 is fixedly connected to the front side of the rotating column 16. The eccentric wheel 18 is in movable contact with the bottom of the contact frame 21, and a spring 22 is fixedly connected to the top of the contact frame 21.

The stirring rod design in the mixer 11 fully considers the fluidity of the material and the mixing effect, ensuring that quicklime and phosphogypsum can fully contact and react quickly during the mixing process, reducing energy consumption and improving productivity. The mixer 11 can automatically adjust the stirring speed and intensity according to the different characteristics of the material, further improving the mixing quality and ensuring the consistency and stability of each batch of material.

[0070] This invention also proposes a method for an online lime mixing system for water-washed phosphogypsum, comprising the following steps:

[0071] S1: First, quicklime is added to the lime box 3, and phosphogypsum and water are added to the mixing box 19. At this time, the electric actuator 5 is controlled to work, and the electric actuator 5 can pull the horizontal plate 6 to descend.

[0072] S2: Then the horizontal plate 6 can synchronously control the movable belt 8 to rotate, the movable belt 8 can control the adjusting plate 9 to rise, at this time the adjusting plate 9 can push the rotating plate 10 to move, at this time the top of the rotating plate 10 can push the adjusting door 4 to move to the left;

[0073] S3: By cyclically controlling the output end of the electric actuator 5 to move, the regulating gate 4 can be cyclically controlled to move. At this time, the regulating gate 4 can control the quicklime to enter the mixing box 19 in batches, effectively preventing the quicklime from entering in large quantities and causing clumping.

[0074] S4: Then the mixer 11 is operated by controlling the mixer 11, which can mix quicklime and phosphogypsum through the mixing rod;

[0075] S5: And control the motor 13 to work. At this time, the output shaft of the motor 13 can control the guide door 14 to rotate. At this time, the guide door 14 rotates and opens to form an inclined surface, which can guide the material inside the mixing box 19 into the reaction box 26 for static reaction.

[0076] S6: Finally, the staff pulls the ring 15 to the left. The ring 15 can control the rotating column 16 to rotate by pulling the belt 17. The rotating column 16 can drive the eccentric wheel 18 to rotate. At this time, the eccentric wheel 18 can contact the bottom of the contact frame 21, thereby pushing the contact frame 21 to move upward. The contact frame 21 can pull the moving plate 23 to rise. At this time, the moving plate 23 can pull the connecting rod 24 to move. At this time, the connecting rod 24 can pull the movable door 25 to the right by its own bottom, thereby controlling the movable door 25 to open. The material inside the reaction tank 26 removes the moisture inside the phosphogypsum through the filter plate 27 to ensure a full dehydration effect.

[0077] Working principle: In actual operation, quicklime is pre-added to the lime box 3, while phosphogypsum and water are added to the mixing box 19. The electric actuator 5 is then controlled to lower the horizontal plate 6. As the horizontal plate 6 moves, it synchronously controls the rotating belt 8 to rotate. When the rotating belt 8 rotates, it controls the adjusting plate 9 to rise. As the adjusting plate 9 moves, it pushes the rotating plate 10 to move. The top of the rotating plate 10 then pushes the adjusting door 4 to the left. The movement of the regulating gate 4 is achieved by cyclically controlling the output end of the electric actuator 5. This cyclical movement of the regulating gate 4 allows for the batch-wise entry of quicklime into the mixing box 19, effectively preventing clumping caused by excessive quicklime entry. Simultaneously, the mixer 11 is controlled to operate, mixing the quicklime and phosphogypsum via a mixing rod. After mixing, the motor 13 is activated, and its output shaft controls the rotation of the guide gate 14. When the guide door 14 rotates and opens to form an inclined plane, it can guide the material inside the mixing box 19 into the reaction box 26 for static reaction. After the mixture reaction is completed, the operator pulls the pull ring 15 to the left. When the pull ring 15 moves, it can pull the pull belt 17 to move. At this time, the pull belt 17 gradually unwinds from the outer wall of the rotating column 16, thereby controlling the rotation of the rotating column 16. When the rotating column 16 rotates, it can drive the eccentric wheel 18 to rotate. When the eccentric wheel 18 rotates, the eccentric wheel 18... It can contact the bottom of the contact frame 21, thereby pushing the contact frame 21 to move upward. As the contact frame 21 moves, the contact frame 21 can pull the moving plate 23 to rise. When the moving plate 23 rises, the moving plate 23 can pull the connecting rod 24 to move. At this time, the connecting rod 24 can pull the movable door 25 to the right through its bottom, thereby controlling the movable door 25 to open. As the movable door 25 opens, the material inside the reaction tank 26 passes through the filter plate 27 to remove the moisture inside the phosphogypsum, ensuring a sufficient dehydration effect.

[0078] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
