Description

Technical Field

[0001] This invention relates to the field of slurry thickening technology, and in particular to a high-efficiency slurry thickener with large feed. Background Technology

[0002] Thickeners are suitable for thickening and dewatering concentrates and tailings in mineral processing plants, and are widely used in metallurgy, chemical industry, coal, non-metallic mineral processing, environmental protection and other industries. Traditional thickeners generally consist of a thickening tank, a rake frame, a transmission device, a rake frame lifting device, a feeding device, a discharging device, and signal safety devices. The rake frame is located at the bottom of the thickener, with a small gap between it and the bottom of the thickener tank. The bottom of the rake frame has inclined plates, the purpose of which is to push the concentrated and deposited material at the bottom towards the center of the bottom when the rake frame rotates. An underflow outlet is located at the center of the bottom of the thickener; the concentrated material is discharged through the underflow outlet, while clear water or the poorly concentrated slurry overflows from the upper end face of the thickener.

[0003] To improve efficiency during slurry concentration, reagents are often added. However, most existing methods involve directly injecting the reagents into the slurry and relying on the reagents to diffuse into the slurry on their own. This method suffers from slow and uneven diffusion, resulting in insufficient concentration efficiency. Summary of the Invention

The second driving member is arranged at one end of the second cylinder away from the first cylinder.

[0008] Preferably, both the first and second annular components are elliptical structures and are fixedly connected to the second cylinder. The first and second annular components are inclined at the same angle, and the guide bolt is in sliding contact with both the first and second annular components.

[0017] 1. This application sets up a feeding component with a guiding mechanism, which includes a first annular component and a second annular component. Driven by a second driving component, the straight pipe used for adding reagents can perform both circular and linear reciprocating motions under the guidance of the guiding mechanism. The circular motion acts as a stirrer, while the linear motion makes the reagent addition more uniform. Using this device can greatly improve the uniformity of reagent addition and help improve the concentration efficiency of slurry.

[0018] 2. This application incorporates a lifting component and a float at the bottom of the first cylinder. During the slurry feeding process, the buoyancy generated by the slurry causes the float to float, which in turn moves the first cylinder upward. With the assistance of the lifting component, the first cylinder is gradually lifted upward. Therefore, during slurry feeding, the impact of newly entering slurry on the slurry inside the thickener is reduced, and the turbulence of the slurry is decreased, allowing the concentrate to settle quickly.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-5 The present invention provides a technical solution:

[0028] A high-efficiency slurry thickener with large feed capacity includes a thickening tank 1. A support frame 2 is installed at the bottom of the thickening tank 1, and a bridge frame 3 is installed at the top of the thickening tank 1. A feeding component is installed inside the thickening tank 1, positioned below the center of the bridge frame 3. A lifting component is installed between the bridge frame 3 and the feeding component. The feeding component is used to feed the slurry into the thickening tank 1. The lifting component can adjust the height of the feeding component, allowing the position of the slurry to change dynamically, avoiding continuous feeding within the thickening tank 1 and reducing the impact of the slurry feeding on the sediment.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the feeding component includes a first cylinder 4 and a second cylinder 5, which are vertically arranged and interconnected. The side of the first cylinder 4 is connected to a slurry feeding system via a feeding pipe. The interior of the second cylinder 5 includes a guide mechanism, a disc 27, a second drive member 28, a second magnet 29, and a third magnet 30. A tube assembly is mounted on the guide mechanism. The output end of the second drive member 28 is connected to the disc 27. The second magnet 29 and the third magnet 30 are respectively located on the upper and lower sides of the tube assembly. The guide mechanism includes a first annular member 18 and a second annular member 19. The first annular member 18 is located outside the second annular member 19, and a guide bolt 20 is provided between the first annular member 18 and the second annular member 19. The tube assembly includes a bent pipe 21, a sleeve 22, and a straight pipe 23 connected in sequence. A first magnet 24 is mounted on the straight pipe 23, and the straight pipe 23 passes through the disc 27. The first annular component 18 and the second annular component 19 are both elliptical in shape and are fixedly connected to the second cylindrical body 5. The first annular component 18 and the second annular component 19 are inclined at the same angle. The guide bolt 20 is in sliding contact with both the first annular component 18 and the second annular component 19. The bent pipe 21 is rotatably connected to the guide bolt 20. The two ends of the sleeve 22 are rotatably connected to the bent pipe 21 and the straight pipe 23, respectively. A sliding sleeve is provided at the connection between the straight pipe 23 and the disc 27, and the sliding sleeve is rotatably connected to the disc 27. The first cylindrical body 4 and the second cylindrical body 5 are both circular cylindrical structures. The first cylindrical body 4 is vertically arranged, and the second cylindrical body 5 is horizontally arranged. The bottom of the first cylindrical body 4 is open. The disc 27 is located at one end of the second cylindrical body 5 near the first cylindrical body 4 and is rotatably connected to the second cylindrical body 5. The second driving component 28 is located at one end of the second cylindrical body 5 away from the first cylindrical body 4. At least three pipe body assemblies are provided, and multiple pipe body assemblies are evenly arranged in a ring around the disc 27. The second driving component 28 can drive the disk 27 to rotate, further causing multiple tube components to rotate synchronously with the disk 27. Simultaneously, under the action of the guiding mechanism, the guide bolt 20 remains between the first annular component 18 and the second annular component 19, moving along an elliptical trajectory. Therefore, the straight tube 23 of the tube component can simultaneously perform circular motion and linear reciprocating motion. The circular motion serves a stirring function, while the linear reciprocating motion serves to uniformly diffuse the agent. The upper magnetic pole of the first magnet 24 attracts the second magnet 29, and the lower magnetic pole of the first magnet 24 attracts the third magnet 30. Both the second magnet 29 and the third magnet 30 are arc-shaped structures, and both are fixedly connected to the inner wall of the second cylinder 5.The mutual attraction between the first magnet 24, the second magnet 29, and the third magnet 30 ensures that the straight tube 23 will not rotate when the tube assembly moves. An annular tube 25 is provided on the inner side of the second annular member 19. A connecting tube 26 is provided between the annular tube 25 and the sleeve 22. The medicine enters the straight tube 23 through the annular tube 25, the connecting tube 26, and the sleeve 22, thereby realizing feeding. The annular tube 25 is rotatably connected to the output end of the second driving member 28. Under the drive of the tube assembly and the connecting tube 26, the annular tube 25 rotates around the output shaft of the second driving member 28.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the lifting component includes a fixed rod 6, a sensor 8, a first driving component 17, and two driving assemblies. A float 7 is mounted on the fixed rod 6. The driving assembly includes a connecting rod 10, a worm gear 12, a rack 14, and a slide rail 15. A connecting seat 9 is mounted on the lower end of the connecting rod 10, and a worm wheel 11 and a gear 13 are mounted on the upper end of the connecting rod 10. A slide block 16 is mounted on the gear 13. Multiple fixed rods 6 are arranged evenly in a ring around the first cylinder 4, and the fixed rods 6 are located at the bottom of the first cylinder 4. The sensor 8 and the connecting seat 9 are both located at the top of the first cylinder 4. A pin is located at the bottom of the connecting rod 10, and a guide groove that mates with the pin is provided on the connecting seat 9. The guide groove is arranged vertically. The worm wheel 11 and the gear 13 are fixedly connected by a shaft, and both are rotatably connected to the connecting rod 10. The two worm gears 12 of the two drive components are coaxially arranged and fixedly connected. The helical directions of the two worm gears 12 are opposite. The output end of the first drive component 17 is fixedly connected to one of the worm gears 12. The sensor 8 is used to detect the distance between the first cylinder 4 and the bridge frame 3. As the slurry continuously enters the thickener 1, the float 7 floats under buoyancy and lifts the first cylinder 4. The pin on the connecting rod 10 can slide along the downward guide groove. When the sensor 8 detects that the distance has shortened, it immediately starts the first drive component 17. The rotation of the worm gear 12 drives the worm wheel 11 to rotate. The worm wheel 11 and the gear 13 are an integral structure. The gear 13 rolls along the rack 14. Therefore, as the two connecting rods 10 move to both sides, it plays the role of lifting the first cylinder 4.

[0031] In summary, the high-efficiency slurry thickener with large feed provided in this embodiment, during operation, feeds slurry through the first cylinder 4 and reagents through the tube assembly. The second drive unit 28 can drive the disc 27 to rotate, further causing multiple tube assemblies to rotate synchronously with the disc 27. Simultaneously, under the action of the guiding mechanism, the guide bolt 20 is always between the first annular member 18 and the second annular member 19, moving along an elliptical trajectory. Therefore, the straight tube 23 of the tube assembly can simultaneously perform circular motion and linear reciprocating motion. During operation, the output shaft of the second drive unit 28 rotates alternately in both directions as the slurry continuously feeds in... When the slurry enters the thickening tank 1, the float 7 floats under buoyancy, lifting the first cylinder 4 upwards. The pin on the connecting rod 10 can slide along the downward guide groove. The sensor 8 detects the shortening distance and then activates the first drive component 17. The worm gear 12 rotates, driving the worm wheel 11 to rotate. The worm wheel 11 and the gear 13 are an integral structure. The gear 13 rolls along the rack 14. Therefore, as the two connecting rods 10 move to both sides, it lifts the first cylinder 4. The lifting component can adjust the height of the feeding component, so that the position of the slurry feeding changes dynamically, avoiding feeding in the thickening tank 1 all the time and reducing the impact of the slurry feeding on the sediment.
