Description

Technical Field

[0001] This invention relates to the field of tailings slag treatment technology, and in particular to a gold tailings slag reuse and concentration treatment device. Background Technology

[0002] In the process of gold mining, grinding, flotation, and other processes generate a large amount of gold tailings slurry with high water content. Tailings slurry not only contains a certain amount of recyclable valuable components but also harmful substances such as heavy metals. Improper handling can cause serious environmental pollution, and large-scale accumulation also occupies valuable land resources. Therefore, thickening treatment equipment is needed to concentrate the tailings slurry. Currently, although the equipment used for tailings slurry thickening can reduce the water content and solid hazards to a certain extent, the following problems still exist in practical applications, limiting the thickening efficiency and effect.

[0003] After initial settling, tailings slurry forms a stratified structure consisting of an upper supernatant, a middle sediment layer, and a lower thick sludge layer. The middle sediment layer, located between the supernatant and thick sludge layers, has a high water content, and due to its own gravity and the influence of the surrounding environment, the water is difficult to drain naturally. Existing equipment designs often focus on simple overflow of the upper supernatant and discharge of the lower thick sludge layer, lacking a dedicated drainage structure and mechanism for the middle sediment layer. This prevents sufficient drainage of water from the middle sediment layer, resulting in a high water content throughout the thickening system and affecting thickening efficiency.

[0004] Furthermore, during tailings dry stacking operations, tailings slurry with high water content cannot meet the requirements for dry stacking, necessitating additional dewatering treatment. When the tailings slurry is reused as a building material or other resource, the high water content also affects its performance and processing technology. Therefore, there is an urgent need to design a gold tailings slag reuse and concentration treatment device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a gold tailings slag reuse and concentration treatment device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gold tailings slag recycling and concentration treatment device includes a main tank, a sludge discharge tank fixedly installed at the bottom of the main tank, and a feed pipe fixedly connected to the side wall of the main tank. It also includes:

[0008] The extraction unit is used to extract the supernatant of gold tailings slag in the main tank. The extraction unit includes an extraction seat fixedly installed on the top of the main tank. A mounting frame is fixedly installed on the top of the extraction seat, and a servo motor is fixedly installed on the mounting frame. The output end of the servo motor is fixedly connected to a reciprocating screw through a reducer, and a rotating rod is fixedly installed at the bottom of the reciprocating screw. Multiple stirring blades are fixedly installed on the side wall of the rotating rod. The multiple stirring blades are used to stir the middle layer sediment of gold tailings slag in the main tank.

[0009] The extrusion section is used to extrude and dewater the gold tailings slag fed into the main tank. The extrusion section includes a threaded section on a rotating rod. A movable plate is threadedly installed on the threaded section, and a fixed ring is fixedly installed at the bottom of the movable plate and is slidably connected to the inner wall of the main tank. The fixed ring cooperates with the feed pipe.

[0010] The water filtration section is used to discharge the water squeezed out of the middle layer sediment of gold tailings slag after the extrusion section is running. It includes multiple drainage grooves opened on the side wall of the main tank, and an annular groove opened on the inner wall of the main tank that communicates with the multiple drainage grooves. A sealing ring is rotatably installed in the annular groove, and multiple water filtration holes are opened on the sealing ring. Two deflection components are installed between the fixed ring and the sealing ring. The deflection components are used to drive the sealing ring to rotate by the downward movement of the fixed ring, so that the water filtration holes are aligned with the drainage grooves.

[0011] The sludge discharge section is used to discharge the lower layer of thick sludge into the sludge discharge tank after the gold tailings slag has been squeezed. The sludge discharge section includes multiple through holes opened at the bottom of the main tank.

[0012] Furthermore, the reciprocating screw is located outside the extraction seat, and the rotating rod is sealed and rotatably connected to the main tank and the extraction seat. A movable ring is threaded onto the reciprocating screw, and multiple fixed rods that are slidably connected to the extraction seat are fixedly installed at the bottom of the movable ring. A piston plate that is sealed and slidably connected to the rotating rod is installed between the ends of the multiple fixed rods located inside the extraction seat.

[0013] Furthermore, the bottom of the extraction seat is fixedly connected to multiple one-way extraction pipes, and each one-way extraction pipe is slidably connected to the moving plate. A spherical extraction head is fixedly installed at the bottom of each one-way extraction pipe. A one-way filter pipe is fixedly connected between the side wall of the extraction seat and the sludge discharge tank, and a one-way discharge pipe is fixedly connected to the side wall of the extraction seat.

[0014] Furthermore, a water storage chamber that cooperates with multiple drainage channels is fixedly installed on the side wall of the main tank, and the water storage chamber is fixedly connected to a one-way discharge pipe, and a drain pipe is fixedly installed at the bottom of the water storage chamber.

[0015] Furthermore, two arc-shaped grooves are formed on the side wall of the annular groove, and a slider is slidably installed in each of the two arc-shaped grooves. Both sliders are fixedly connected to the sealing ring, and springs are installed between the two sliders and the two arc-shaped grooves.

[0016] Furthermore, an installation ring is fixedly installed on the rotating rod, and a corrugated pipe that cooperates with the rotating rod is installed between the top of the installation ring and the bottom of the movable plate.

[0017] Furthermore, the deflection assembly consists of a push rod and a wedge. The push rod is fixedly installed at the bottom of the fixing ring, and the wedge is fixedly installed on the inner wall of the sealing ring. The wedge and the push rod are positioned correspondingly, and the initial distance between the top of the push rod and the top of the wedge is greater than or equal to the diameter of the feed pipe.

[0018] Furthermore, a circular groove is provided at the bottom of the main tank, and an opening and closing plate is rotatably installed in the circular groove. The opening and closing plate is provided with multiple alignment holes that cooperate with the corresponding through holes.

[0019] Furthermore, an arc-shaped rack is fixedly installed on the side wall of the opening and closing plate, a mounting base is fixedly installed on the side wall of the main tank, and a second servo motor is fixedly installed on the mounting base. The output end of the second servo motor is fixedly connected to a drive gear through a round rod, and the drive gear meshes with the arc-shaped rack. A controller is fixedly installed on the main tank, and the controller is electrically connected to both the first servo motor and the second servo motor.

[0020] Compared with existing technologies, the advantages of this invention are:

[0021] 1: By using the stirring blades and water filter section set in the middle section of the main tank, the middle layer sediment can be slowly stirred, making it easier to remove gas and water, greatly reducing the water content of the concentrated tailings slurry, and facilitating subsequent processing.

[0022] 2: By setting up the extraction section, the supernatant can be extracted in real time during the concentration process, which improves the concentration efficiency and avoids the problem of the supernatant mixing with the middle layer precipitate again, which would increase the difficulty of solid-liquid separation.

[0023] 3: Through the cooperation of the extrusion section and the sludge discharge section, the tailings slurry can be continuously pressurized during the thickening process, and the tailings slurry can be automatically discharged into the sludge discharge tank after thickening, further reducing the water content of the thickened tailings slurry.

[0024] In summary, this invention can slowly agitate the sediment in the middle layer of tailings slurry while extracting the supernatant, and gradually apply pressure to the tailings slurry as the concentration progresses, which greatly increases the discharge rate of water in the tailings slurry, reduces the water content of the concentrated tailings slurry, and facilitates subsequent processing.

Detailed Implementation

[0038] Reference Figures 1-2 A gold tailings slag reuse and concentration treatment device includes a main tank 1, a sludge discharge tank 2 fixedly installed at the bottom of the main tank 1, and a feed pipe 3 fixedly connected to the side wall of the main tank 1. The feed pipe 3 is used to input the tailings slurry to be concentrated into the main tank 1. The other end of the feed pipe 3 is connected to the storage area of ​​the gold tailings slag. A corresponding pump can be used to input the stored gold tailings slag into the main tank 1 through the feed pipe 3. The selection and application of the pump are existing technologies and will not be described in detail here. The sludge discharge tank 2 is used to discharge the concentrated lower layer of sludge from the bottom of the main tank 1. Multiple support legs are fixedly installed at the bottom of the sludge discharge tank 2 to support the device. In order to facilitate the control of the discharge of the lower layer of sludge, a valve is set at the bottom of the sludge discharge tank 2 to control the opening and closing of the sludge discharge tank 2. The valve used is an existing product, and its working principle and specific structure will not be described in detail here.

[0039] Reference Figures 1-12 A gold tailings slag reuse and concentration treatment device further includes an extraction unit. The extraction unit is used to extract the supernatant of the gold tailings slag in the main tank 1. The extraction unit includes an extraction seat 4 fixedly installed on the top of the main tank 1. An installation frame 5 is fixedly installed on the top of the extraction seat 4, and a servo motor 6 is fixedly installed on the installation frame 5. The output end of the servo motor 6 is fixedly connected to a reciprocating screw 7 through a reducer. A rotating rod 8 is fixedly installed at the bottom of the reciprocating screw 7. Multiple stirring blades 9 are fixedly installed on the side wall of the rotating rod 8. The multiple stirring blades 9 are used to stir the middle layer sediment of the gold tailings slag in the main tank 1. After the gold tailings slag input into the main tank 1 has been allowed to settle, the servo motor 6 is started, and the rotating rod 8 is slowly rotated through the reducer, so that the stirring blades 9 slowly stir the middle layer sediment of the gold tailings slag, so that the gas can be smoothly released and the water can be discharged, thereby reducing the water content in the middle layer sediment.

[0040] The reciprocating screw 7 is located outside the extraction seat 4. The rotating rod 8 is sealed and rotatably connected to the main tank 1 and the extraction seat 4. A moving ring 34 is threaded onto the reciprocating screw 7, and multiple fixed rods 35 that are slidably connected to the extraction seat 4 are fixedly installed at the bottom of the moving ring 34. A piston plate 14 that is sealed and slidably connected to the rotating rod 8 is installed between the ends of the multiple fixed rods 35 located inside the extraction seat 4. When the servo motor 6 is working, the piston plate 14 is driven to move up and down reciprocally inside the extraction seat 4 through the cooperation of the reciprocating screw 7 and the moving ring 34. When the piston plate 14 moves up inside the extraction seat 4, the air pressure at the bottom of the extraction seat 4 decreases, generating negative pressure. When the piston plate 14 moves down, the air pressure at the bottom of the extraction seat 4 increases, generating positive pressure.

[0041] The bottom of the extraction seat 4 is fixedly connected to multiple one-way extraction pipes 12, and each one-way extraction pipe 12 is slidably connected to the moving plate 10. A spherical extraction head 13 is fixedly installed at the bottom of each one-way extraction pipe 12. The extraction head 13 is used to intercept impurities such as sludge. When the piston plate 14 moves upward in the extraction seat 4, the one-way extraction pipe 12 draws the supernatant of the gold tailings slag in the main tank 1 into the extraction seat 4 for storage. A one-way filter pipe 36 is fixedly connected between the side wall of the extraction seat 4 and the sludge discharge tank 2. A filter screen is also provided at the connection end of the one-way filter pipe 36 and the sludge discharge tank 2. The one-way filter pipe 36 is used to extract some of the water remaining in the lower thick sludge layer and store it in the extraction seat 4, further reducing the water content of the lower thick sludge layer.

[0042] A one-way discharge pipe 15 is fixedly connected to the side wall of the extraction seat 4. When the piston plate 14 moves down in the extraction seat 4, the water stored in the extraction seat 4 is discharged in one direction through the one-way discharge pipe 15. One-way valves in corresponding directions are provided in the one-way extraction pipe 12, the one-way discharge pipe 15 and the one-way filter pipe 36 to limit the flow direction of water. The one-way valve is an existing product, and its working principle and specific structure will not be described here.

[0043] The extrusion section is used to extrude and dewater the gold tailings slag input into the main tank 1. The extrusion section includes a threaded section on the rotating rod 8, on which a movable plate 10 is threadedly installed. A fixing ring 11 is fixedly installed at the bottom of the movable plate 10 and is slidably connected to the inner wall of the main tank 1. The fixing ring 11 cooperates with the feed pipe 3. When the servo motor 6 rotates forward, the rotation of the rotating rod 8, through the setting of its threaded section and the movement limiting effect of multiple one-way extraction pipes 12 on the movable plate 10, causes the movable plate 10 to move downward in the main tank 1. When the movable plate 10 moves downward, the fixing ring 11 moves downward at the same time. After the fixing ring 11 moves downward, it blocks the feed pipe 3. At this time, the feed pipe 3 and the main tank are closed. The space between sections 1 and 2 is sealed. The downward movement of the moving plate 10 will compress the gold tailings slag remaining in the main tank 1. During the compression process, the one-way extraction pipe 12 continues to extract the supernatant, thus effectively improving drainage during the compression process. In addition, due to the presence of the fixed ring 11 during the compression process, the problem of gold tailings slag backflow or damage to the feed pipe 3 due to excessive pressure caused by the pressure increase in the feed pipe 3 can be avoided. After the concentration of the batch of gold tailings slag is completed, the servo motor 6 is reversed, which will cause the moving plate 10 to drive the fixed ring 11 to move upward and reset, so that the feed pipe 3 is reopened to continue the concentration of the remaining gold tailings slag to be processed.

[0044] An installation ring 25 is fixedly installed on the rotating rod 8, and a bellows 26 that cooperates with the rotating rod 8 is installed between the top of the installation ring 25 and the bottom of the moving plate 10. The bellows 26 is designed to ensure the sealing effect between the moving plate 10 and the rotating rod 8, and to prevent slag from entering the threaded section of the rotating rod 8, which would cause the moving plate 10 to be obstructed.

[0045] The filtration section is used to discharge the water squeezed out of the middle layer sediment of gold tailings slag after the extrusion section has been running. It includes multiple drainage channels 21 on the side wall of the main tank 1, and an annular groove 18 on the inner wall of the main tank 1 that communicates with the multiple drainage channels 21. A sealing ring 19 is rotatably installed in the annular groove 18, and multiple water filtering holes 20 are opened on the sealing ring 19. When the moving plate 10 is not moving downward, the drainage channels 21 and the water filtering holes 20 are staggered. At this time, the sealing ring 19 blocks the drainage channels 21, and the main tank 1 is in a sealed state. When the moving plate 10 moves downward to extrude the gold tailings slag, the sealing ring 19 rotates in the annular groove 18 so that the water filtering holes 20 are aligned with the drainage channels 21. At this time, the water squeezed out can be directly discharged from the middle of the main tank 1, further reducing the water content of the concentrated gold tailings slag.

[0046] Two arc-shaped grooves are formed on the side wall of the annular groove 18, and sliders 23 are slidably installed in both arc-shaped grooves. Both sliders 23 are fixedly connected to the sealing ring 19, and springs 24 are installed between the two sliders 23 and the two arc-shaped grooves. The elastic force of the springs 24 can keep the sealing ring 19 at a constant angle in the main tank 1 when it is not driven by the outside, so as to effectively seal the drain groove 21. Two deflection components are installed between the fixed ring 11 and the sealing ring 19. The deflection components are used to drive the sealing ring 19 to rotate by the downward movement of the fixed ring 11, so that the filter hole 20 is aligned with the drain groove 21. The assembly consists of a push rod 17 and a wedge 22. The push rod 17 is fixedly installed at the bottom of the fixing ring 11, and the wedge 22 is fixedly installed on the inner wall of the sealing ring 19. The wedge 22 and the push rod 17 are positioned opposite each other. The initial distance between the top of the push rod 17 and the top of the wedge 22 is greater than or equal to the diameter of the feed pipe 3. The advantage of this size design is that when the fixing ring 11 does not move down to close the feed pipe 3, the push rod 17 does not contact the wedge 22. However, when the feed pipe 3 is closed, the push rod 17 begins to contact the wedge 22. Subsequently, as the moving plate 10 continues to move down, the drain groove 21 is gradually opened, allowing the squeezed water to be discharged smoothly.

[0047] A water storage chamber 16 is fixedly installed on the side wall of the main tank 1, which cooperates with multiple drainage troughs 21. The water storage chamber 16 is fixedly connected to a one-way discharge pipe 15. A drain pipe is fixedly installed at the bottom of the water storage chamber 16. The drain pipe can be an existing pipe with a valve, which can periodically discharge the supernatant stored in the water storage chamber 16.

[0048] The sludge discharge section is used to discharge the lower layer of thick sludge into the sludge discharge tank 2 after the gold tailings slag has been squeezed. The sludge discharge section includes multiple through holes 27 at the bottom of the main tank 1. A circular groove is provided at the bottom of the main tank 1, and a rotatable opening and closing plate 28 is installed in the circular groove. The opening and closing plate 28 has multiple alignment holes 29 that mate with the corresponding through holes 27. An arc-shaped rack 30 is fixedly installed on the side wall of the opening and closing plate 28. A mounting base 31 is fixedly installed on the side wall of the main tank 1, and a servo motor 32 is fixedly installed on the mounting base 31. The output end of the servo motor 32 is fixedly connected to a drive gear 33 through a round rod, and the drive gear 33 meshes with the arc-shaped rack 30. A control device is fixedly installed on the main tank 1. The controller is electrically connected to both servo motor 6 and servo motor 32. When servo motor 6 rotates forward, causing the moving plate 10 to move downward to its maximum stroke, the controller stops servo motor 6. Then, the controller causes servo motor 32 to rotate forward, causing the drive gear 33 to drive the arc rack 30 to rotate until the alignment hole 29 on the opening / closing plate 28 is aligned with the through hole 27. At this time, the concentrated tailings slurry enters the sludge discharge tank 2 through the through hole 27. After that, the controller causes servo motor 32 and servo motor 6 to rotate in reverse simultaneously, resetting the opening / closing plate 28 and the moving plate 10. The controller controls servo motor 6 and servo motor 32 using the existing electrical control method, which will not be described in detail here.

[0049] Both servo motor 1 (6) and servo motor 2 (32) can be ACM6004M2H servo motors, and the controller can be KV-16AT.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
