Description

Technical Field

[0001] This invention belongs to the field of metal extraction, specifically relating to an apparatus for recovering gold from gold and copper mine tailings liquid. Background Technology

[0002] With the increasing depletion of high-grade gold resources globally, the development and utilization of gold-copper associated ores and low-grade, difficult-to-process ores has become the mainstream of the gold industry. Given the "poor, fine, and complex" characteristics of these ores, hydrometallurgical cyanide leaching remains the most mature gold extraction process. However, the tailings solution produced by this process has the following significant unique characteristics, posing a major challenge to the deep recovery of gold.

[0003] Chinese Patent CN2546456Y, published on April 23, 2003, discloses an apparatus for recovering gold from tailings liquid. The apparatus includes a ore distribution box with an inlet and several outlets. The outlets of the ore distribution box are connected in parallel to the inlets of several stirred adsorption tanks via pipelines. The bottom of the stirred adsorption tank is provided with a discharge port, which is connected to a lime-chlorine mixing tank via a pipeline. Each stirred adsorption tank is provided with a discharge port at the top, which is connected to the top of a collection box via a pipeline. The bottom of the collection box is provided with an outlet, which is connected to a mud pump via a pipeline.

[0004] The aforementioned application document describes using a stirring rod to agitate the activated carbon and tailings liquid within the device. However, when agitating finely broken activated carbon, the mixing effect between the activated carbon and the tailings liquid is poor, thus affecting the recovery efficiency of the device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an apparatus for recovering gold from gold-copper mine tailings liquid, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides an apparatus for recovering gold from gold-copper mine tailings liquid, comprising a recovery chamber, an inlet and a outlet on both sides of the recovery chamber, an agitator driven by a servo motor installed inside the recovery chamber, a mesh cage for holding activated carbon installed inside the recovery chamber, a conveying hose for conveying quicklime and chlorine gas installed on the top of the recovery chamber, a fixing rod installed inside the recovery chamber, a pressing plate and a fixing toothed ring fixedly connected to the bottom of the fixing rod, a rotating rod rotatably connected to the side of the agitator, an agitating plate fixedly connected to the outside of the rotating rod, a sliding groove inside the agitator, a transverse plate slidably connected inside the sliding groove, and a transmission component for transmission between the fixing toothed ring and the transverse plate; The recycling bin is equipped with a vibration assembly inside, and a conveying assembly is installed on the top of the recycling bin.

[0007] Preferably, the transmission component includes a gear fixed to the outside of the rotating rod, a spring is mounted on one side of the transverse plate, and a pressing rod is mounted on the other side of the transverse plate. With this device, during the mixing and stirring operation of tailings liquid and activated carbon in the mesh cage, the longitudinal rotation of the stirring plate and the intermittent reciprocating movement of the transverse plate further improve the mixing efficiency of the finely crushed activated carbon and tailings liquid.

[0008] Preferably, the first gear is located at the bottom of the fixed gear ring, and the first gear and the fixed gear ring are in a meshing state.

[0009] Preferably, when the device is in operation, the extrusion plate can be in contact with the extrusion rod.

A second spring is fitted to the top of the inner sliding plate, a movable rod is fixedly connected to the bottom of the inner sliding plate, a force-bearing rod is fixedly connected to the side of the movable rod, and a vibration plate is fixedly connected to the bottom of the movable rod. The vibration plate has a through hole, and a cover plate is rotatably connected to the top of the vibration plate via a torsion spring rod. By configuring the vibration assembly, the tailings liquid at the bottom of the recovery bin can be intermittently turned upwards, preventing the tailings liquid from being unused and improving the recovery efficiency of the device.

[0011] Preferably, when the oscillation component is in the activated state, the force-bearing rod and the stirring plate are in contact with each other.

By configuring the conveying assembly, the lime and chlorine gas in the conveying hose can be rotatably injected into the recovery chamber, increasing its coverage area and thus further improving the recovery efficiency of the device.

[0014] Preferably, only half of the teeth are provided on the outer side of the second gear, and the second gear can mesh with the third gear through these teeth.

[0015] The advantages of this application are: (1) In this application, when the stirring rod is used to mix and stir the tailings liquid and the activated carbon in the cage, it is combined with the fixed rod, the extrusion plate, the fixed tooth ring, the rotating rod, the gear, the sliding groove, the spring and the extrusion rod.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] Example 1, please refer to Figures 1-4 An apparatus for recovering gold from gold-copper mine tailings includes a recovery chamber 100. The recovery chamber 100 has an inlet 200 and a outlet 300 on its two sides. Inside the recovery chamber 100 is a stirring rod 400 driven by a servo motor, and inside the recovery chamber 100 is a mesh cage 500 for holding activated carbon. The top of the recovery chamber 100 is equipped with a conveying hose 600 for conveying quicklime and chlorine gas. Inside the recovery chamber 100 is a fixing rod 701, with a pressing plate 702 and a fixing toothed ring 703 fixedly connected to its bottom. A rotating rod 704 is rotatably connected to the side of the stirring rod 400. The tailings to be treated are fed into the recovery chamber 100 through the inlet 200, mixing with the activated carbon in the mesh cage 500. The stirring rod 400 is then activated to rotate and agitate the tailings, causing the rotating rod 704 connected to it to rotate as well.

[0022] A stirring plate 706 is fixedly connected to the outside of the rotating rod 704. A sliding groove 707 is provided inside the stirring plate 706. A transverse plate 709 is slidably connected inside the sliding groove 707. A transmission component for transmission is assembled between the fixed gear ring 703 and the transverse plate 709. The transmission component includes a gear 705 fixed to the outside of the rotating rod 704. When the rotating rod 704 rotates, it drives the gear 705, which is fixedly connected to it, to rotate. The gear 705 is located at the bottom of the fixed gear ring 703, and the gear 705 and the fixed gear ring 703 are in a meshing state. When the gear 705 rotates, it is restricted by the fixed gear ring 703 during its revolution, so that the gear 705 rotates synchronously on its own axis during its revolution. The rotating gear 705 drives the rotating rod 704, which is fixedly connected to it, to rotate, so that the rotating rod 704 drives the stirring plate 706 fixed to its outside to rotate. A spring 708 is mounted on one side of the transverse plate 709, and a pressing rod 710 is mounted on the other side. When the device is in operation, the pressing plate 702 can contact the pressing rod 710. When the pressing rod 710 rotates to the side position of the pressing plate 702, it is restricted by the pressing plate 702, which is fixed to the recovery chamber 100 by the fixing rod 701. This causes the pressing rod 710 to drive the transverse plate 709 to compress the spring 708 and move a certain distance within the sliding groove 707. As the agitator 706 continues to rotate, the pressing rod 710 loses the restriction of the pressing plate 702 and returns to its original position under the action of the spring 708. In this way, the agitator 706 can rotate longitudinally, while the transverse plate 709 performs intermittent reciprocating movement, further improving the mixing efficiency of the finer activated carbon and tailings liquid.

[0023] In practical use, the tailings liquid to be treated is fed into the recovery bin 100 through the inlet 200, where it mixes with the activated carbon in the mesh cage 500. The stirring rod 400 is then activated to rotate and stir the liquid. The rotating rod 400 drives the rotating rod 704 connected to it to rotate, which in turn drives the gear 705 fixedly connected to it to rotate. During its revolution, the gear 705 is constrained by the fixed gear ring 703 with which it meshes, causing the gear 705 to rotate synchronously on its own axis. The rotating gear 705 then drives the rotating rod 704 fixedly connected to it to rotate on its own axis, causing the rotating rod 705 to rotate synchronously on its own axis. 04 drives the agitator plate 706 fixed on its outer side to rotate; the rotating agitator plate 706 can drive the spring 708, the transverse plate 709 and the extrusion rod 710 mounted on the agitator plate 706 to rotate together, and when the extrusion rod 710 rotates to the side position of the extrusion plate 702, the extrusion rod 710 can be restricted by the extrusion plate 702 fixed to the recovery chamber 100 by the fixing rod 701, so that the extrusion rod 710 drives the transverse plate 709 to compress the spring 708 and move a certain distance in the sliding groove 707; as the agitator plate 706 continues to rotate, the extrusion rod 710 loses the restriction of the extrusion plate 702 and can be reset under the action of the spring 708.

[0024] Example 2, please refer to Figures 4-7 Based on Embodiment 1, the recycling bin 100 is internally equipped with a vibration assembly 800. The vibration assembly 800 includes an inner sliding plate 801 slidably connected to the stirring rod 400. A second spring 802 is mounted on the top of the inner sliding plate 801. The end of the second spring 802 away from the inner sliding plate 801 is mounted on the inner wall of the stirring rod 400. A movable rod 803 is fixedly connected to the bottom of the inner sliding plate 801. A force-bearing rod 804 is fixedly connected to the side of the movable rod 803. When the vibration assembly 800 is in operation, the force-bearing rod 804 is in contact with the stirring plate 706. When the stirring plate 706 rotates to the force-bearing rod 804, it can squeeze the force-bearing rod 804. The squeezed force-bearing rod 804 then moves downward. The moving force-bearing rod 804 can drive the movable rod 803 fixedly connected to it to move downward together, so that the movable rod 803 drives the inner sliding plate 801 fixedly connected to it to move downward. At this time, the inner sliding plate 801 stretches the second spring 802 and moves downward.

[0025] A vibrating plate 805 is fixedly connected to the bottom of the moving rod 803. When the moving rod 803 moves downward, it can drive the vibrating plate 805 fixedly connected to it to move downward synchronously.

[0026] The vibrating plate 805 has a through hole 806, and the top of the vibrating plate 805 is rotatably connected to the cover plate 808 via a torsion spring rod 807. When the vibrating plate 805 moves downward synchronously, the tailings liquid squeezes the cover plate 808, causing the cover plate 808 to drive the torsion spring rod 807 to rotate at a certain angle, and the tailings liquid then passes through the through hole 806. When the vibrating plate 805 moves upward, the tailings liquid at the top of the vibrating plate 805 vibrates upward, and the tailings liquid at the bottom of the recovery bin 100 flows back into the mesh cage 500, preventing the tailings liquid at that location from being unused and improving the recovery effect of the device.

[0027] In practical use, when the agitator plate 706 rotates to the force rod 804, it can compress the force rod 804. The compressed force rod 804 then moves downward. The moving force rod 804 can drive the fixedly connected moving rod 803 to move downward together, causing the moving rod 803 to drive the fixedly connected inner slide plate 801 to move downward. At this time, the inner slide plate 801 stretches the second spring 802 and moves downward. The moving rod 803, which is in a downward moving state, can drive the fixedly connected vibrating plate 805 to move downward synchronously. Because the top of the vibrating plate 805 is connected to the rotation of the torsion spring rod 807, the vibration plate 805 is rotated downward. With the cover plate 808 attached, as the vibrating plate 805 moves downward, the tailings liquid squeezes the cover plate 808, causing the cover plate 808 to drive the torsion spring rod 807 to rotate at a certain angle, and the tailings liquid then passes through the through hole 806. As the stirring plate 706 continues to rotate, the force rod 804 is no longer restricted by the stirring plate 706, causing the moving rod 803 to reset under the action of the spring 802. The moving rod 803 in the reset state can drive the vibrating plate 805 fixedly connected to it to move upward, thereby vibrating the tailings liquid at the top of the vibrating plate 805 upward, and returning the tailings liquid at the bottom of the recovery bin 100 to the mesh cage 500.

[0028] Example 3, please refer to Figures 8-9 Based on Embodiments 1 and 2, a conveying assembly 900 is installed on the top of the recycling bin 100. The conveying assembly 900 includes a gear 901 fixed to the outside of the stirring rod 400. When the stirring rod 400 is rotating, it can drive the gear 901 fixedly connected to it to rotate.

[0029] The side of the recycling bin 100 is rotatably connected to a torsion spring rod 902, which has an internal torsion spring. Gears 903 and 904 are fixedly connected to the outer side of the torsion spring rod 902. Gear 901 has only half of its teeth on its outer side, allowing it to mesh with gear 903. When the toothed side of gear 901 rotates to the position of gear 903, gear 901 drives gear 903 to rotate, which in turn drives the torsion spring rod 902 to rotate. The rotating torsion spring rod 902 then drives the gear 904 to rotate.

[0030] A rotating gear ring 905 is rotatably connected to the top of the recycling bin 100, and a rotating bin 906 is fixedly connected to the inner wall of the rotating gear ring 905. When the gear 904 rotates, it drives the rotating gear ring 905, which is fixedly connected to it, to rotate. The rotating gear ring 905, in its rotating state, drives the rotating bin 906, which is fixedly connected to it, to rotate.

[0031] The bottom of the rotating chamber 906 is equipped with an output head 907 that communicates with it, so that when the rotating chamber 906 rotates, it can drive the output head 907 at its bottom to rotate. As the gear 2 901 continues to rotate, when the side of the gear 2 901 without teeth rotates to the gear 3 903, the gear 3 903 loses its restraint and can be reset under the action of the torsion spring rod 2 902. In this way, the four output heads 907 can reciprocate within a certain range, injecting the lime chlorine gas in the conveying hose 600 into the recovery chamber 100, increasing its coverage area, thereby further improving the recovery efficiency of the device.

[0032] In practical use, when the stirring rod 400 is rotating, it drives the gear 2 901, which is fixedly connected to it, to rotate. When the toothed side of gear 2 901 rotates to gear 3 903, gear 2 901 drives gear 3 903, which is meshing with it, to rotate. Gear 3 903 then drives torsion spring rod 2 902, which is fixedly connected to it, to rotate. Gear 2 902, which is rotating, drives gear 4 904, which is fixedly connected to it, to rotate. Gear 4 904 then drives rotating gear ring 905, which is meshing with it, to rotate. Rotating gear ring 905, which is rotating, drives rotating chamber 906, which is fixedly connected to it, to rotate. The output head 907 mounted at its bottom rotates; as gear two 901 continues to rotate, when the side of gear two 901 without teeth rotates to gear three 903, gear three 903 loses its restraint and can rotate in the opposite direction under the action of the torsion spring inside torsion spring rod two 902, thus resetting. This causes torsion spring rod two 902 to drive gear four 904, which is fixedly connected to it, to reset. Gear four 904, which is in the reverse rotation state, can drive the rotating gear ring 905 that meshes with it to reset, thus causing the rotating gear ring 905 to drive the rotating chamber 906 and the output head 907 to reset. In this way, the four output heads 907 can reciprocate within a certain range, rotating and injecting the lime chlorine gas in the conveying hose 600 into the recovery chamber 100.
