Description

Technical Field

[0001] This utility model relates to the field of hydrometallurgical technology, specifically to an in-situ leaching device. Background Technology

[0002] In the process of hydrometallurgical leaching reaction, the leaching equipment is the core reaction unit, and its performance directly affects production efficiency and product quality.

[0003] Especially for equipment simulating in-situ leaching processes, existing equipment suffers from serious technical defects. Current mainstream leaching equipment (such as mechanically stirred tanks and air-stirred tanks) cannot meet the technical requirements of in-situ leaching in actual operation. Laboratory tests mainly use column leaching tests to simulate their main technical parameters, and the following technical problems are commonly found: 1) The equipment's base plate structure design has strength defects. Under the combined effects of ore pressure and slurry over a long period, stress concentration easily occurs, leading to weld cracking and base plate deformation, severely affecting the equipment's service life; 2) Traditional dosing systems mostly use single-point injection methods, lacking intelligent flow control functions, making it difficult to achieve uniform mixing of reagents and slurry, resulting in excessive or insufficient local reactions. This not only reduces metal recovery rates (usually a loss of 3-5%) but also increases reagent consumption by more than 15%. More seriously, internal components (such as guide tubes and screens) are prone to structural blockage when processing high-viscosity slurries, especially when processing complex ore bodies with a silicon content exceeding 8%, significantly reducing equipment operating rate (usually less than 85%). Utility Model Content

[0004] The purpose of this invention is to provide an in-situ leaching device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An in-situ leaching device includes a control cabinet, inside which a drug storage tank is placed, and a delivery pump for conveying the drug solution in the storage tank is installed on the outside of the control cabinet. A fixing frame is fixed to the side of the control cabinet, and a geared motor is fixed to the lower end of the fixing frame. A dosing mechanism is detachably installed at the output end of the geared motor to achieve uniform dosing of the drug solution. The dosing mechanism is located above the reaction tank.

[0006] Preferably, the control cabinet has a control panel fixed to its front end, and an inspection port is connected to the control cabinet via hinges. The infusion pump and the dosing pipe on the control cabinet are interconnected. Through the above structure, the normal dosing can be guaranteed.

[0007] Preferably, the output shaft of the geared motor has a rotation angle range of 0°-90°, and the rotational speed of the output shaft of the geared motor is 1-10 r / min. Through the above structure, the angle adjustment function of the dosing mechanism can be realized, thereby providing a basic guarantee for achieving uniform dosing.

[0008] Preferably, the dosing mechanism includes a threaded joint that is threadedly connected to the output shaft of the geared motor, and the threaded joint is fixed to the main pipe. A branch pipe is fixed to the side of the main pipe, and the lower end face of the branch pipe is uniformly provided with liquid outlet holes with a diameter of <1mm. Through the above structure, uniform dosing can be achieved, thereby ensuring uniform contact between the liquid and the ore and ensuring the normal progress of the reaction.

[0009] Preferably, a drain valve is fixed to the lower end face of the reaction tank, a support plate is fixed inside the reaction tank, and a first slide rail is also fixed inside the reaction tank.

The lower base plate is in contact with the upper base plate, and the upper base plate is connected to the second slide rail through a ball ring. Through the above structure, the lower base plate can rotate relative to the upper base plate, providing a basic guarantee for the normal operation of the device.

[0011] Preferably, the upper base plate is also uniformly provided with through holes that correspond one-to-one with the circular holes on the lower base plate. The through hole structure on the upper base plate is larger at the top and smaller at the bottom. The upper diameter of the through hole on the upper base plate is 4mm-10mm, and the lower diameter of the through hole on the upper base plate is 1mm-3mm. At the same time, the lower diameter of the through hole on the upper base plate is equal to the diameter of the circular hole on the lower base plate.

[0012] Preferably, the upper base plate has a slot, and the slot is nested with a block fixed inside the reaction vessel for positioning. The reaction vessel is also connected to a rotating handle by a bearing, and a friction wheel is fixed on the rotating handle. The friction wheel contacts the lower end face of the lower base plate.

[0022] Please see Figures 1-4 The in-situ leaching equipment provided by this utility model includes a control cabinet 1, a drug storage tank is placed inside the control cabinet 1, and a delivery pump for conveying the drug solution in the drug storage tank is installed on the outside of the control cabinet 1. A fixing frame 2 is fixed on the side of the control cabinet 1, and a reduction motor 3 is fixed on the lower end face of the fixing frame 2. A dosing mechanism 4 is detachably installed on the output end of the reduction motor 3 to achieve uniform dosing of the drug solution. The dosing mechanism 4 is located above the reaction tank 5.

[0023] A drain valve 501 is fixed to the lower end face of the reaction tank 5, and a support plate 502 is fixed inside the reaction tank 5. A first slide rail 503 is also fixed inside the reaction tank 5. The first slide rail 503 and the second slide rail 505 are connected by a ball ring 504. The second slide rail 505 is fixed to the outside of the lower base plate 506, and the lower base plate 506 has evenly spaced round holes. The lower base plate 506 is in contact with the upper base plate 507, and the upper base plate 507 is connected to the second slide rail 505 by the ball ring 504.

[0024] The upper base plate 507 is also evenly provided with through holes that correspond one-to-one with the round holes on the lower base plate 506. The upper base plate 507 is provided with a slot 508, and the slot 508 is nested with the slot block 509 fixed in the reaction tank 5 to achieve positioning. The reaction tank 5 is also connected to a rotating handle 510 by a bearing, and a friction wheel 511 is fixed on the rotating handle 510, and the friction wheel 511 is in contact with the lower end face of the lower base plate 506.

[0025] In some specific implementations, the through hole structure of the upper base plate 507 is larger at the top and smaller at the bottom, and the upper diameter of the through hole of the upper base plate 507 is 4mm-10mm, the lower diameter of the through hole of the upper base plate 507 is 1mm-3mm, and the lower diameter of the through hole of the upper base plate 507 is equal to the diameter of the circular hole on the lower base plate 506.

[0026] When using this in-situ leaching equipment, the main pipe 402 is first disassembled through the threaded action between the threaded joint 401 and the output shaft of the geared motor 3. Then, the ball ring 504 is installed with the first slide rail 503. After installation, the lower base plate 506 is installed. At this time, the second slide rail 505 on the outer side of the lower base plate 506 contacts the ball ring 504, and the lower base plate 506 contacts the friction wheel 511 and the support plate 502. Then, the ball ring 504 is placed on the upper side of the second slide rail 505, and the upper base plate 507 is installed to contact the friction wheel 511 until the upper base plate 507 contacts the lower base plate 506. At this time, the upper base plate 507 simultaneously contacts the ball ring 504 on the upper side of the second slide rail 505. With the nesting action between the slot 508 and the block 509, the upper base plate 507 can be limited. After installation, rotating the handle 510 drives the friction wheel 511 to rotate. The rotation of the friction wheel 511 exerts a force on the lower base plate 506, allowing the lower base plate 506 to rotate slowly. This allows for the adjustment of the position of the circular hole on the lower base plate 506 and the through hole on the upper base plate 507, ensuring that the circular hole on the base plate 506 and the through hole on the upper base plate 507 are misaligned in the initial state. The lower base plate 506 can block the through hole on the upper base plate 507, meaning that liquid on the upper base plate 507 cannot drip normally through the through hole.

[0027] A control panel 101 is fixed on the front face of the control cabinet 1, and an inspection port 102 is connected to the control cabinet 1 via a hinge. The infusion pump and the dosing pipe 103 on the control cabinet 1 are connected to each other.

[0028] In some embodiments, the rotation angle range of the output shaft of the geared motor 3 is 0°-90°, and the rotational speed of the output shaft of the geared motor 3 is 1-10 r / min.

[0029] The dosing mechanism 4 includes a threaded joint 401 that is threadedly connected to the output shaft of the geared motor 3. The threaded joint 401 is fixed to the main pipe 402. A branch pipe 403 is fixed to the side of the main pipe 402. At the same time, the lower end face of the branch pipe 403 is evenly provided with liquid outlet holes 404, and the diameter of the liquid outlet holes 404 is <1mm.

[0030] After the upper base plate 507 and the lower base plate 506 are installed, as follows: Figure 1 and Figure 2 As shown, an appropriate amount of mineral sample is added to the reaction tank 5. At this time, the mineral sample is stored on the upper bottom plate 507. After the mineral sample is added, the main pipe 402 is installed through the thread action between the threaded joint 401 and the output shaft of the reduction motor 3. Then, according to actual needs, the upper infusion pump is controlled by the control panel 101 to transport the reagent in the storage tank in the control cabinet 1 to the main pipe 402 through the dosing pipe 103. The reagent is then dispersed into the branch pipe 403 through the main pipe 402. Finally, the reagent drips through multiple outlet holes 404 at the lower end of the branch pipe 403, thereby realizing the reagent addition. During the reagent addition process, the reduction motor 3 drives the threaded joint 401 and the main pipe 402 to reciprocate and swing within 0-90°, thereby adjusting the position of the branch pipe 403 and thus adjusting the reagent addition position, effectively achieving uniform addition of the reagent and ensuring uniform contact between the reagent and the mineral. After the reagent addition is completed, wait for the reagent and the mineral to react for a period of time (e.g., 20 days). After the reaction is complete, rotate the handle 510 again to drive the friction wheel 511 to rotate. The rotation of the friction wheel 511 exerts a force on the lower base plate 506, allowing the lower base plate 506 to rotate slowly. This aligns the circular hole on the lower base plate 506 with the through hole on the upper base plate 507, facilitating the dripping of the reaction liquid. Finally, the reaction liquid can be collected by opening the drain valve 501. During the dripping of the liquid, the structure of the through hole on the upper base plate 507, which has a larger diameter at the top and a smaller diameter at the bottom, effectively avoids the problem of mineral blockage and ensures the normal collection of the liquid.

[0031] The above description is only a preferred embodiment of this utility model. It should be noted that due to the limitations of written expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principle of this utility model, and can also combine the above technical features in an appropriate manner. These improvements, modifications, changes, or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without modification, should all be considered within the protection scope of this utility model.
