Description

Technical Field

[0001] This utility model relates to the technical field of gold and silver replacement zinc powder addition device, specifically a gold and silver replacement device for quantitative addition of zinc powder. Background Technology

[0002] The gold and silver displacement apparatus is a core piece of equipment in hydrometallurgy used to recover precious metals from gold and silver-containing solutions. The zinc powder displacement method has become the mainstream due to its high efficiency and stability. The zinc powder displacement method involves adding zinc powder to the cyanide solution, allowing the zinc powder to react fully with the solution.

[0003] The common method of adding zinc powder is to continuously add zinc powder into the displacement tank through a feeder to carry out the displacement reaction. However, the addition speed of the traditional feeder is unstable and the zinc powder is not evenly distributed in the displacement tank after being added, which leads to uneven contact between the zinc powder and the precious liquid, affecting the reaction rate and completeness of the subsequent displacement reaction.

[0004] In view of this, we propose a gold-silver displacement device for quantitative addition of zinc powder. Utility Model Content

[0005] The purpose of this invention is to provide a gold and silver replacement device for quantitative addition of zinc powder, which solves the problems mentioned in the background art.

[0014] By employing the above technical solution, this utility model provides a gold and silver displacement device for quantitative addition of zinc powder, which has at least the following beneficial effects:

[0015] (1) By setting up a displacement tank, a zinc box, a sample feeding mechanism and a feeding mechanism, this utility model enables the zinc box to be uniformly transported and stably vibrated by the sample feeding mechanism when zinc powder is added to the displacement tank, so that the zinc powder can be added evenly into the displacement tank.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Please see Figures 1-6 A gold-silver displacement device for quantitative zinc powder addition includes a displacement tank 1, which provides space for gold-silver displacement. A zinc-adding box 2 is installed inside the displacement tank 1 for temporary storage and addition of zinc powder. A uniform sample plate 21 is installed near the bottom of the zinc-adding box 2 to ensure more uniform zinc powder distribution. A feeding mechanism 4 is installed between the displacement tank 1 and the zinc-adding box 2. The feeding mechanism 4, through reciprocating conveying and vibration of the zinc-adding box 2, ensures more stable and uniform addition of zinc powder to the displacement tank 1.

[0029] The zinc filling box 2 is connected to a sample injection mechanism 3, which is used to uniformly replenish zinc powder in the zinc filling box 2 and make the zinc powder evenly distributed inside the zinc filling box 2, so as to facilitate the uniformity of subsequent addition of zinc powder to the replacement cell 1.

[0030] Please see Figures 1-4 The feeding mechanism 4 includes two working frames 41, which are fixedly installed at the top of the replacement tank 1 near both ends. A lead screw 42 is rotatably installed between the two working frames 41 near one end, and a limit rod 43 is fixedly installed between the two working frames 41 near the other end. A movable rod 44 is threadedly connected to the lead screw 42, and the movable rod 44 is slidably connected to the limit rod 43. A reciprocating motor is fixedly installed on the lead screw 42, which can drive the lead screw 42 to rotate intermittently in both directions. This rotation of the lead screw 42 causes the movable rod 44 to move back along the lead screw 42. The limit rod 43 plays a limiting role, preventing the movable rod 44 from rotating.

[0031] The movable rod 44 and the zinc addition box 2 are slidably connected, so that the zinc addition box 2 can move up and down along the movable rod 44 to generate vibration. A plurality of springs are installed between the bottom surface of the movable rod 44 and the top surface of the zinc addition box 2. The springs are used to adjust the amplitude of vibration according to the weight of the zinc addition box 2. On both sides of the top of the replacement tank 1, corrugated rods 46 are fixedly installed. Arc-shaped blocks 45 are fixedly installed at both ends of the zinc addition box 2. The arc-shaped blocks 45 are in contact with the corrugated rods 46. The contact between the arc-shaped blocks 45 and the corrugated rods 46 causes the arc-shaped blocks 45 to move up and down along the corrugated rods 46, thereby driving the zinc addition box 2 to generate vibration.

[0032] When the movable rod 44 moves, it will drive the zinc addition box 2 to move synchronously. The displacement of the zinc addition box 2 drives the arc-shaped block 45 to move along the upper surface of the corrugated rod 46, so that the zinc addition box 2 generates vibration during the movement, making the zinc addition of the zinc addition box 2 more stable. When the weight of the zinc powder in the zinc addition box 2 is reduced by the spring, the vibration amplitude of the zinc addition box 2 is reduced, which is used to adapt to the feeding amount of the zinc powder when the quality of the zinc powder in the zinc addition box 2 changes, making the zinc addition of the zinc addition box 2 more uniform and stable.

[0033] Please refer to Figures 5-6 , the feeding mechanism 3 includes a feed box 31 for storing zinc powder. One side of the feed box 31 near the bottom end is fixedly connected to the feed inlet of the screw feeder 32. A hopper 33 is slidably installed through the top end of the zinc addition box 2. The hopper 33 is fixedly connected to the movable rod 44, making the feeding of the hopper 33 more stable. The top end of the hopper 33 is a frustum structure with a larger top and a smaller bottom, making the feeding more stable and not prone to leakage and scattering of materials. The discharge port of the screw feeder 32 is located at the top end of the hopper 33. By operating the screw feeder 32, the zinc powder in the feed box 31 can be conveyed into the hopper 33, and then conveyed into the zinc addition box 2 through the hopper 33 for replenishment. Since the discharge amount of the screw feeder 32 is fixed, the feeding amount can be adjusted by the discharge time.

[0034] A plurality of chutes 35 are provided on the inner surface of the replacement tank 1. A sealing plate 34 is slidably installed in the chutes 35. The cross-section of the chutes 35 is a "convex" structure, which plays a limiting role, so that the sealing plate 34 can only move along the chutes 35 and cannot脱离 the chutes 35.

[0035] The sealing plate 34 and the zinc addition box 2 are slidably connected, and the structure of the connection part is a "convex" structure, so that the sealing plate 34 can only be horizontally separated from the zinc addition box 2. The sealing plate 34 and the replacement tank 1 are elastically connected by a spring, so that the sealing plate 34 is on the same horizontal line as the empty zinc addition box 2 when not working. It is convenient to connect the zinc addition box 2 and the sealing plate 34.

[0036] When the zinc powder in the zinc filling box 2 is exhausted and needs to be replenished, the zinc filling box 2 is displaced and connected to the sealing plate 34. The sealing plate 34 seals the bottom of the zinc filling box 2, preventing leakage during filling. Simultaneously, the zinc powder exerts a slight impact on the zinc filling box 2 during filling. However, due to the multiple springs at both the top and bottom of the zinc filling box 2, this impact force is amplified, causing the zinc filling box 2 to vibrate reciprocally. This vibration ensures that the zinc powder is evenly distributed inside the zinc filling box 2. Meanwhile, the hopper 33 is fixedly mounted on the movable rod 44, so the vibration of the zinc filling box 2 does not affect the filling of the hopper 33.

[0037] A gold-silver displacement device for quantitative addition of zinc powder, the working principle of which is as follows:

[0038] By starting the reciprocating motor, the lead screw 42 can be driven to rotate intermittently in both directions. This rotation of the lead screw 42 causes the movable rod 44 to move back and forth along the lead screw 42. When the movable rod 44 moves, it causes the zinc filling box 2 to move synchronously. The displacement of the zinc filling box 2 causes the arc-shaped block 45 to move along the upper surface of the corrugated rod 46, thus causing the zinc filling box 2 to vibrate during the movement, making the zinc filling box 2 more stable when adding zinc. The spring reduces the vibration amplitude of the zinc filling box 2 when the weight of zinc powder inside decreases, which is used to adapt to the amount of zinc powder added when the weight of zinc powder inside the zinc filling box 2 changes, making the addition of zinc powder in the zinc filling box 2 more uniform and stable.

[0039] It should be noted that when the reciprocating motor drives the movable rod 44 to move, the movable rod 44 will not contact the sealing plate 34. After the zinc powder in the zinc filling box 2 is added, the reciprocating motor drives the movable rod 44 to continuously move towards the sealing plate 34 until the sealing plate 34 and the zinc filling box 2 are completely engaged, at which point the motor stops. The screw feeder 32 can transport the zinc powder in the material box 31 to the hopper 33, and then from the hopper 33 to the zinc filling box 2 for replenishment. Since the output of the screw feeder 32 is fixed, the feeding amount can be adjusted by adjusting the output time.

[0040] Simultaneously, during the feeding process, the zinc powder exerts a slight impact on the zinc feeding box 2. However, due to the multiple springs at both the top and bottom of the zinc feeding box 2, this impact force is amplified, causing the zinc feeding box 2 to vibrate reciprocally. This vibration ensures that the zinc powder is evenly distributed within the zinc feeding box 2. After feeding is complete, starting the reciprocating motor will drive the zinc feeding box 2 to uniformly feed the zinc powder.
