Description
Technical Field
[0001] The utility model belongs to the technical field of calcium carbonate production, in particular to a slurry clarification device for calcium carbonate production. Background Art
[0002] Calcium carbonate is a widely used chemical raw material. Its production process usually includes multiple steps such as ore mining, crushing, grinding, reaction, etc. During the production process, slurry containing unreacted raw materials, impurities, suspended matter, etc. will be produced. These slurries need to be clarified to remove impurities and suspended matter and improve the purity and quality of the product.
[0003] At present, the traditional slurry clarification equipment for calcium carbonate production pours the slurry to be treated into a clarification box at one time or in batches. Then, the operator needs to add clarifiers, such as flocculants and coagulants, into the box based on experience or preset formulas to promote the separation of suspended matter, colloids and tiny particles in the slurry from the slurry through coagulation and precipitation. Since the equipment lacks a delivery mechanism, it is often difficult to adjust the dosage of the clarifier in real time according to the specific properties of the slurry. When the dosage is insufficient, the suspended matter and impurities cannot be effectively removed, resulting in the substandard quality of the clarified liquid. Additional processing steps or extended processing time may be required, increasing energy consumption and costs. On the contrary, excessive addition of clarifiers will not only fail to further improve the clarification effect, but may introduce new pollutants, such as residual chemicals, which will affect the subsequent use or discharge of the clarified liquid. At the same time, excessive use of clarifiers will also increase the cost of reagents and cause waste of resources. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0023] As Figures 1 to 6 shown, the present utility model provides a slurry clarification device for calcium carbonate production, which includes a clarification tank 1. A first feed pipe 2 and a storage tank 3 are fixedly installed at the top end of the clarification tank 1. A second feed pipe 4 is fixedly installed at the top end of the storage tank 3, and a guide plate 5 is fixedly installed inside the second feed pipe 4.
[0024] A control mechanism is arranged inside the bottom end of the storage tank 3. The control mechanism includes a plugging plate 10 which is slidably connected inside the bottom end of the storage tank 3. A square hole 11 is formed in the middle of the surface of the plugging plate 10. The top end of the plugging plate 10 is in contact with the bottom end of the guide plate 5. A square shell 6 is fixedly installed at the right end of the storage tank 3. A rotating disk 7 located inside the square shell 6 is rotatably connected to the right end of the storage tank 3. The number of the rotating disks 7 is two, and a connecting rod 8 is fixedly installed on the opposite side. A motor 9 is fixedly installed at the rear end of the square shell 6. The output end of the motor 9 extends into the inside of the square shell 6 and is fixedly connected to the rotating disk 7 at the rear end. A spring 12 located above the plugging plate 10 is fixedly installed at the left end inside the storage tank 3. A connecting plate 13 is fixedly installed at the top end of the plugging plate 10. The right end of the spring 12 is fixedly connected to the left side of the spring 12. A belt 14 is fixedly installed at the right end of the connecting plate 13. The other end of the belt 14 penetrates through the storage tank 3 and extends into the inside of the square shell 6 and is fixedly connected to the surface of the rotating disk 7. A feed port 15 located below the plugging plate 10 is fixedly installed at the top end of the clarification tank 1.
[0025] Adopting the above solution: The operator pours the calcium carbonate slurry into the interior of the first feed pipe 2. Then, the slurry will pass through the first feed pipe 2 and enter the interior of the clarification tank 1. The clarifying agent can be poured into the interior of the second feed pipe 4. Then, the clarifying agent will enter the interior of the storage tank 3. Then, the storage tank 3 can store the clarifying agent. When the clarifying agent is needed, the controller in the device will drive the motor 9 to rotate the rear rotating disk 7. Then, the rear rotating disk 7 will drive the connecting rod 8 and the front rotating disk 7 to rotate. Then, the two rotating disks 7 will wind the belt 14 around their surfaces. Then, the belt 14 will drive the connecting plate 13 to move. When the connecting plate 13 moves, the spring 12 will be stretched. Then, the connecting plate 13 will drive the plugging plate 10 and the square hole 11 to move. Then, the surface of the square hole 11 will coincide with the bottom end of the guiding plate 5 and the top end of the feed port 15. Then, the clarifying agent inside the storage tank 3 will pass through the guiding plate 5 and the square hole 11 and enter the interior of the feed port 15. Then, the clarifying agent will enter the interior of the clarification tank 1. Then, the clarifying agent will combine with the slurry, so that the suspended matters and impurities in the slurry will precipitate;
[0026] When the clarifying agent is put into the specified dosage, the controller will drive the motor 9 again to rotate the two rotating disks 7 in the reverse direction. Then, the belt 14 will disengage from the surfaces of the two rotating disks 7. Then, the stretched spring 12 will pull the plugging plate 10 and the connecting plate 13 to reset. Then, the square hole 11 will move away from the bottom end of the guiding plate 5. Then, the plugging plate 10 will plug the guiding plate 5. Then, the injection of the clarifying agent inside the storage tank 3 will stop. Finally, by controlling the dosage of the clarifying agent, the clarifying effect can be fully exerted, the impurities and suspended matters in the slurry can be effectively removed, the clarification effect can be improved, the utilization rate of the clarifying agent can be increased, and the clarification cost can be reduced.
[0027] As Figure 4 and Figure 5 shown, the top end of the plugging plate 10 is fixedly installed with positioning plates 16 located at the left and right ends of the guiding plate 5. The opposite sides of the positioning plates 16 are inclined and are in full contact with the surface of the guiding plate 5. The right side of the storage tank 3 is rotatably connected with limiting wheels 19. The number of the limiting wheels 19 is two and they are symmetrically designed horizontally about the center of the storage tank 3. The belt 14 can move on the surface of the limiting wheels 19.
[0028] Adopt the above solution: Through the design of the positioning plates 16, when the belt 14 pulls the plugging plate 10 to move, the two positioning plates 16 will move along. Since the opposite sides of the positioning plates 16 are inclined, the left positioning plate 16 will fit against the surface of the guide plate 5. During the fitting process, the plugging plate 10 will stop moving, and then the square hole 11 on the surface of the plugging plate 10 will coincide with the bottom end of the guide plate 5 and the top end of the feed inlet 15. When the plugging plate 10 resets, the right positioning plate 16 will also fit against the right side of the feed inlet 15, which will also block the movement of the plugging plate 10. As a result, the square hole 11 will move away from the bottom end of the guide plate 5. Through the design of the limiting wheel 19, since the surface of the belt 14 is in contact with the surface of the limiting wheel 19, due to the frictional force between the belt 14 and the limiting wheel 19, when the belt 14 moves, it will drive the limiting wheel 19 to rotate, which can then protect the belt 14 and limit the moving direction of the belt 14, and then make the belt 14 pull the plugging plate 10 to move smoothly.
[0029] As Figure 4 and Figure 6 As shown in the figure, sliding grooves 17 are formed on both the front and rear sides inside the storage box 3. Inside the front and rear sides of the plugging plate 10, pulleys 18 are rotatably connected and located inside the sliding grooves 17. The surface of the pulley 18 is in contact with the inner wall of the sliding groove 17. A plug 20 is arranged on the surface of the second feed pipe 4, and a contact block 21 located inside the second feed pipe 4 is fixedly installed at the top inside the plug 20.
[0030] Adopt the above solution: Through the design of the sliding grooves 17 and the pulleys 18, when the plugging plate 10 moves, the plugging plate 10 will drive the pulleys 18 to move. Since the surface of the pulley 18 is in contact with the inner wall of the sliding groove 17, when the plugging plate 10 moves, the pulley 18 will roll inside the sliding groove 17, which can make the movement of the plugging plate 10 smoother. Through the design of the plug 20 and the contact block 21, after pouring the clarifying agent into the storage box 3 from the first feed pipe 2, the plug 20 can be sleeved on the surface of the second feed pipe 4. During the sleeving process, the contact block 21 will enter the inside of the second feed pipe 4. Since the surface of the contact block 21 is in contact with the inner wall of the second feed pipe 4, the clarifying agent residue on the inner wall of the second feed pipe 4 can be cleaned.
[0031] As Figure 2 and Figure 3As shown in the figure, it further includes a stirring mechanism, which is arranged in the middle of the top of the clarification tank 1. The stirring mechanism includes a driving component 24, which is fixedly connected to the middle of the top of the clarification tank 1. The output end of the driving component 24 extends into the clarification tank 1 and is fixedly installed with a rotating rod 25. The surface of the rotating rod 25 is fixedly installed with stirring paddles 26. The top of the surface of the rotating rod 25 is fixedly installed with a fixing ring 27 located inside the clarification tank 1. The surface of the fixing ring 27 is fixedly installed with a square plate 28. One end of the square plate 28 close to the inner wall of the clarification tank 1 is fixedly installed with a scraping plate 29. The middle of the bottom end of the clarification tank 1 is fixedly installed with a sewage discharge valve 22, and the rear end of the surface of the clarification tank 1 is fixedly installed with a liquid discharge valve 23.
[0032] Adopting the above solution: Through the design of the stirring mechanism, when the clarifying agent combines with the slurry, the driving component 24 can be driven to make the rotating rod 25 rotate. Then the rotating rod 25 will drive the stirring paddles 26 to rotate. Then the rotating stirring paddles 26 can stir the slurry and the clarifying agent, so as to make their combination more sufficient and improve the precipitation efficiency. When cleaning the clarification tank 1, the driving component 24 can be driven again to make the rotating rod 25 rotate. Then the rotating rod 25 will drive the fixing ring 27 and the square plate 28 to rotate. The square plate 28 will drive the scraping plate 29 to rotate. Since the surface of the scraping plate 29 is attached to the inner wall of the clarification tank 1, the slurry on the inner wall of the clarification tank 1 can be scraped off, thus increasing the cleaning efficiency. Through the design of the sewage discharge valve 22 and the liquid discharge valve 23, after the suspension and impurities in the slurry precipitate, the liquid discharge valve 23 can be opened, and then the separated slurry will be discharged from the inside of the liquid discharge valve 23. After the slurry is discharged, the sewage discharge valve 22 can be opened, and then the impurities precipitated at the bottom end of the inner wall of the clarification tank 1 will be discharged from the inside of the sewage discharge valve 22.
[0033] The working principle and usage process of the present utility model:
[0034] First, the operator can inject the slurry into the clarification tank 1 and pour the clarifying agent into the storage tank 3. When the clarifying agent is needed, the controller drives the motor 9 to make the two rotating disks 7 rotate. Then the rotating disks 7 will wind the belt 14 on their surfaces. Then the belt 14 will pull the connecting plate 13 and the plugging plate 10 to move. When the connecting plate 13 moves, the spring 12 will be stretched. Then the plugging plate 10 will drive the positioning plate 16 to move. When the left positioning plate 16 contacts the left side of the guiding plate 5, the surface of the square hole 11 will coincide with the bottom end of the guiding plate 5 and the top end of the feed port 15. Then the clarifying agent inside the storage tank 3 will pass through the feed port 15 and enter the clarification tank 1. Then the clarifying agent will combine with the slurry, so that the suspension and impurities in the slurry will precipitate.
[0035] When the clarifying agent is put into the specified dose, the controller will drive the motor 9 again to make the two rotating disks 7 rotate in the reverse direction. Then, the belt 14 will separate from the surface of the rotating disk 7. Then, the stretched spring 12 will reset the blocking plate 10. Then, the blocking plate 10 can block the guiding plate 5. Then, the feeding of the clarifying agent inside the storage tank 3 will stop. After the suspension and impurities have settled, the drain valve 23 can be opened. Then, the separated slurry will be discharged from the inside of the drain valve 23. After the slurry has been discharged, the sewage discharge valve 22 can be opened. Then, the precipitated impurities can be discharged from the inside of the sewage discharge valve 22, and finally the operation process is completed.
