Description

Technical Field

[0001] This utility model relates to the field of tailings treatment technology, specifically a screening shaking table for tailings treatment. Background Technology

[0002] Tailings treatment refers to the process of physically and chemically treating the solid waste remaining after ore has undergone mineral processing techniques such as crushing, grinding, and separation to extract valuable components. A shaking screen for tailings treatment is a specialized device used for reprocessing tailings. Through its unique shaking and washing action, it separates particles based on differences in density, size, and shape to achieve the purpose of recovering valuable minerals or further purifying the tailings.

[0003] The existing shaking tables consume a large amount of water during use, and the water flowing down from the top of the shaking table is discharged directly without being reused, resulting in excessively high water extraction costs. In addition, some extremely fine valuable minerals will enter the tailings water with the water flow, and direct discharge means the permanent loss of this part of the resources, thereby reducing the overall recovery rate. Utility Model Content

[0004] The purpose of this invention is to provide a screening shaking table for tailings treatment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tailings treatment screening shaking table, comprising a base, a drive mechanism, and a shaking table body. The drive mechanism is installed on one side of the top of the base, and the shaking table body is arranged above the other side of the base. The output end of the drive mechanism is connected to the shaking table body via a connecting rod. A clear water tank is installed on one side of the top of the shaking table body. A mud inlet pipe is connected to one side of the top of the clear water tank, and a water inlet pipe is installed in the middle of the top of the clear water tank. A first collection tank is connected to the side of the top of the shaking table body away from the clear water tank, and a second collection tank is connected to the side of the top of the shaking table body away from the drive mechanism. The first collection tank and the second collection tank are connected and used to collect the water flow left on the top surface of the shaking table body. Below the No. 2 collection tank is a No. 1 water tank, and the No. 2 water tank is located on one side of the outer wall of the No. 1 water tank, and a sedimentation tank is located on one side of the outer wall of the No. 2 water tank. The No. 1 water tank, the No. 2 water tank, and the sedimentation tank are all used to process the collected water flow. A reflux pump is installed in the middle of the outer wall of the sedimentation tank, and a reflux hose is connected to the output end of the reflux pump. The reflux pump and the reflux hose are used to transport the treated water to the inlet pipe for reuse.

[0006] By recycling and treating the wastewater from the shaking table, the amount of fresh water replenishment can be reduced by more than 90%, and the cost of wastewater treatment and discharge can be reduced.

[0007] Preferably, a filter screen is connected to the middle of the inner wall of the second collection tank, and the filter screen is located below the top surface of the shaking table body. One side of the outer wall of the filter screen is connected to the shaking table body. The bottom of the first water tank is fixedly connected to the base, and a first filter plate is installed at the top of the inner wall of the first water tank.

[0008] The water flowing down from the top of the shaker will be collected by the No. 1 and No. 2 collection tanks. The collected water will then pass through a filter screen, which will filter the water and block the mineral particles inside the water.

[0009] Preferably, a first conveying pipe is connected to one side of the bottom of the first water tank, and the bottom of the first conveying pipe is connected to the second water tank. The first conveying pipe is inclined, and the top input end of the first conveying pipe is located below the first filter plate.

[0010] After initial treatment by the filter screen, the water flows into the No. 1 water tank. At this point, the water undergoes secondary filtration through the No. 1 filter plate inside the No. 1 water tank. The water that has undergone secondary filtration through the No. 1 filter plate then travels to the No. 2 water tank through the No. 1 delivery pipe.

[0011] Preferably, the bottom of the second water tank is fixedly connected to the base, and a second filter plate is installed at the bottom of the inside of the second water tank. A water pump is connected to the middle of the outer wall of the second water tank, and the water pump input end is located above the second filter plate. The bottom of the water pump is connected to the base through a support seat.

[0012] As the water flow to the No. 2 water tank increases, it will come into contact with the No. 2 filter plate at the bottom of the No. 2 water tank. At this time, the water flow will be filtered again through the No. 2 filter plate. Then, the return pump will be started to generate suction, so that the water flow after being filtered again will reach the sedimentation tank through the No. 2 delivery pipe.

[0013] Preferably, the output end of the water pump is fixedly connected to a second conveying pipe, and the second conveying pipe has a "Z" shaped structure. The bottom end of the second conveying pipe is connected to the sedimentation tank. The sedimentation tank and the bottom end of the return pump are both fixedly connected to the base. The top output end of the return hose is located inside the clear water tank.

[0014] After the water flows into the sedimentation tank and undergoes sedimentation and stratification, the return pump is started to draw the water inside the sedimentation tank away to the return hose. The input end of the return pump is located in the middle of the sedimentation tank to prevent the sediment particles inside the sedimentation tank from being drawn in. Then, the water that has undergone multiple treatments is transported to the inlet pipe through the return hose.

[0015] Preferably, the outer walls of the first collection tank are welded with limiting seats on both sides, and the bottom of the limiting seats is connected to a limiting plate. The limiting plate has a limiting hole corresponding to the limiting seat, and one side of the outer wall of the limiting plate is fixedly connected to the outer wall of the shaking table body.

[0016] By moving the No. 2 collection tank upwards, the fixing seat on the outer wall of the No. 2 collection tank is disconnected from the fixing plate, thus removing the limiting effect on the No. 2 collection tank. The No. 2 collection tank can then be removed to process the mineral particles accumulated on the surface of the filter screen.

[0017] Preferably, the outer walls of the second collection tank are welded with fixed seats on both sides, and the bottom of the fixed seats is connected to a fixed plate. The fixed plate has a fixed hole corresponding to the fixed seat, and one side of the fixed plate wall is fixedly connected to the outer wall of the shaking table body.

[0018] By moving the No. 1 collection slot upwards, the limiting seat and the limiting plate are disconnected, thus completing the disassembly of the No. 1 collection slot.

[0019] As can be seen from the above, the tailings treatment screening shaking table provided by this utility model has the following beneficial effects.

[0020] 1. Wastewater left on the top surface of the shaking table is collected through the No. 1 and No. 2 collection tanks. The shaking table wastewater is then treated multiple times and recycled, thereby reducing the amount of fresh water replenishment and the cost of external discharge. Moreover, using recycled water with relatively stable composition is more conducive to maintaining the stability of the sorting process than using fresh water with potentially fluctuating composition, thereby improving the concentrate grade and recovery rate.

[0021] 2. By vertically moving the No. 1 and No. 2 collection tanks, the disassembly and installation of the No. 1 and No. 2 collection tanks can be completed, thus facilitating the flexible use of the No. 1 and No. 2 collection tanks by the staff. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7 This utility model provides a technical solution: a tailings treatment screening shaking table, including a base 1, a drive mechanism 2 and a shaking table body 3. The drive mechanism 2 is installed on one side of the top of the base 1, and the shaking table body 3 is arranged on the other side of the base 1. The output end of the drive mechanism 2 is connected to the shaking table body 3 through a connecting rod. A clear water tank 4 is installed on one side of the top of the shaking table body 3. A mud inlet pipe 5 is connected to one side of the top of the clear water tank 4, and a water inlet pipe 6 is installed in the middle of the top of the clear water tank 4. A first collection tank 7 is connected to the side of the top of the shaking table body 3 away from the clear water tank 4, and a second collection tank 8 is connected to the side of the top of the shaking table body 3 away from the drive mechanism 2. The first collection tank 7 and the second collection tank 8 are connected to each other. The first collection tank 7 and the second collection tank 8 are used to collect the water flow left on the top surface of the shaking table body 3. Below the No. 2 collection tank 8, there is a No. 1 water tank 10, and a No. 2 water tank 13 is installed on one side of the outer wall of the No. 1 water tank 10, the No. 2 water tank 13 and the sedimentation tank 17 are all used to process the collected water flow. A return pump 18 is installed in the middle of the outer wall of the sedimentation tank 17, and a return hose 19 is connected to the output end of the return pump 18. The return pump 18 and the return hose 19 are used to transport the treated water to the inlet pipe 6 for reuse. A filter screen 9 is connected to the middle of the inner wall of the second collection tank 8, and the filter screen 9 is located below the top surface of the shaking table body 3. One side of the outer wall of the filter screen 9 is connected to the shaking table body 3. The bottom end of the first water tank 10 is fixedly connected to the base 1, and a first filter plate 11 is installed at the top of the inner wall of the first water tank 10. A first conveying pipe 12 is connected to one side of the bottom end of the first water tank 10, and the bottom end of the first conveying pipe 12 is connected to the second water tank 13. The first conveying pipe 12 is inclined, and its top input end is located below the first filter plate 11. The bottom end of the second water tank 13 is connected to the base 1. The base 1 is fixedly connected, and the bottom of the second water tank 13 is equipped with a second filter plate 14. The middle of the outer wall of the second water tank 13 is connected to a water pump 15, and the input end of the water pump 15 is located above the second filter plate 14. The bottom end of the water pump 15 is connected to the base 1 through a support seat. The output end of the water pump 15 is fixedly connected to a second conveying pipe 16, and the second conveying pipe 16 has a "Z" shaped structure. The bottom end of the second conveying pipe 16 is connected to a sedimentation tank 17. The bottom ends of the sedimentation tank 17 and the return pump 18 are both fixedly connected to the base 1. The top output end of the return hose 19 is located inside the clear water tank 4.

[0026] In practice, the drive mechanism 2 and the shaking table body 3 are first placed in the designated position in the factory through the base 1. Then, the slurry is poured into the mud inlet pipe 5, and clean water is poured into the clean water tank 4 through the water inlet pipe 6. The clean water and slurry are then mixed so that the slurry is evenly distributed across the width of the entire shaking table surface. Then, the drive mechanism 2 is started so that the shaking table body 3 moves asymmetrically back and forth. This movement loosens the particle group on the table surface and quickly stratifies it according to density: high-density particles sink to the bottom and low-density particles are on the top layer. Due to the asymmetry of the bed surface movement, high-density particles at the bottom crawl along the grooves of the lepidocrocite, slowly and continuously pushed towards the concentrate end of the bed. Simultaneously, a strong lateral water flow washes over the bed surface, carrying away the lower-density particles in the upper layers, which have insufficient contact with the bed surface. These particles flow towards the tailings end along the slope of the bed. Ultimately, particles of different densities and sizes form a fan-shaped band on the bed surface due to their different trajectories. The concentrate—the densest and most appropriately sized particles—reaches the farthest, uppermost corner of the bed. The secondary concentrate—particles of intermediate density—are distributed in a band in the middle of the bed. The tailings—the least dense gangue particles—are washed away first by the water flow and are then processed by a shaking screen (this is existing technology).

[0027] See Figures 3-5The water flowing down from the top of the shaker will be collected by the first collection tank 7 and the second collection tank 8. The collected water will then pass through the filter screen 9, which will filter the water and block the mineral particles inside the water. After the water has been initially treated by the filter screen 9, it will fall into the first water tank 10. At this time, the water will be filtered a second time by the first filter plate 11 inside the first water tank 10. The water that has been filtered a second time by the first filter plate 11 will then reach the second water tank 13 through the first delivery pipe 12. As the water flow to the No. 2 water tank 13 increases, it will come into contact with the No. 2 filter plate 14 at the bottom of the No. 2 water tank 13. At this time, the water flow is filtered again through the No. 2 filter plate 14. Then, the return pump 18 is started to generate suction, so that the water flow after being filtered again reaches the sedimentation tank 17 through the No. 2 delivery pipe 16. After the water flows to the sedimentation tank 17 and undergoes sedimentation and stratification, the return pump 18 is started to pump the water inside the sedimentation tank 17 to the return hose 19. The input end of the return pump 18 is located in the middle of the sedimentation tank 17 to prevent the sediment particles inside the sedimentation tank 17 from being pumped out. Then, the water that has undergone multiple treatments is transported to the water inlet pipe 6 through the return hose 19, thereby reusing the water flowing down from the top of the shaker and reducing water costs. By recycling and treating the wastewater from the shaking table, more than 90% of the fresh water replenishment can be reduced, as well as the cost of wastewater treatment and discharge. Furthermore, the mineral processing, especially reagent flotation, is very sensitive to the pH value and ion concentration of the water. Using relatively stable circulating water is more conducive to maintaining the stability of the separation process than using fresh water whose composition may fluctuate, thereby improving the concentrate grade and recovery rate.

[0028] See Figure 2 , Figures 5-7 Limiting seats 20 are welded to both sides of the outer wall of the No. 1 collection tank 7, and the bottom end of the limiting seat 20 is connected to the limiting plate 21. The limiting plate 21 has a limiting hole corresponding to the limiting seat 20, and one side of the outer wall of the limiting plate 21 is fixedly connected to the outer wall of the shaking table body 3. Fixing seats 22 are welded to both sides of the outer wall of the No. 2 collection tank 8, and the bottom end of the fixing seat 22 is connected to the fixing plate 23. The fixing plate 23 has a fixing hole corresponding to the fixing seat 22, and one side of the wall of the fixing plate 23 is fixedly connected to the outer wall of the shaking table body 3.

[0029] In practice, when it is necessary to process the ore particles screened by the shaking table, simply move the No. 2 collection tank 8 upward so that the limiting seat 20 on the outer wall of the No. 2 collection tank 8 is disconnected from the limiting plate 21, thereby canceling the limiting of the No. 2 collection tank 8, and then remove the No. 2 collection tank 8 to process the ore particles accumulated on the surface of the filter screen 9; and simply move the No. 1 collection tank 7 upward so that the fixing seat 22 is disconnected from the fixing plate 23, thereby completing the disassembly of the No. 1 collection tank 7, thus facilitating the flexible use of the No. 1 collection tank 7 and the No. 2 collection tank 8 by the staff. Subsequently, simply move the first collection slot 7 and the second collection slot 8 down so that the limiting seat 20 is inserted into the limiting plate 21 and the fixing seat 22 is inserted into the fixing plate 23, thus limiting the first collection slot 7 and the second collection slot 8, and then install the first collection slot 7 and the second collection slot 8 back onto the top surface of the shaking table.

[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
