Description

Technical Field

[0001] This utility model relates to the field of mineral slurry leaching technology, and in particular to a mineral slurry leaching and dissolution reaction device. Background Technology

[0002] Leaching refers to the process of extracting soluble substances from solids using chemical solvents; it is also known as extraction. The chemical solvent used in leaching is called the leaching agent, the solution obtained after leaching is called the leachate, and the remaining solid is called the residue. The leaching effect is expressed as the leaching rate, which is the percentage of soluble substances in the solid that dissolve into the leachate. In hydrometallurgy, the solids leached are metallurgical intermediates such as ores, concentrates, roasted sand or matte, flue dust, and anode mud. Commonly used leaching agents in industry are water, acid, alkali, and salt solutions. Leaching low-grade raw materials consumes a large amount of solvent, so the leaching agent must be inexpensive and economically regenerable.

[0003] Currently, in slurry leaching, the grinding fineness directly affects the degree of liberation of gold particles. Grinding too finely increases energy consumption and cost, while grinding too coarsely prevents gold particles from being fully liberated, affecting the leaching effect. However, the crushing size is not adjustable, making it difficult to feed larger ore into the crushing bucket, which can easily cause blockage and jamming. Furthermore, larger ore can put pressure on the crushing blades, affecting their service life. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a mineral slurry leaching and dissolving reaction device, which aims to improve the problems that large ores are difficult to put into the crushing bucket and are prone to blockage and jamming, and that large ores will put pressure on the crushing blades and affect their service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mineral slurry leaching and dissolving reaction device, comprising a base, two support plates fixed on the upper surface of the base, a reaction tank disposed between the two support plates, a fixing sleeve fixed on the outer surface of the reaction tank, and the fixing sleeve rotatably mounted on the support plates, a feeding hopper mounted on the support plates, a feeding port and a feeding cover on the feeding hopper, a crushing mechanism disposed inside the feeding hopper, a discharge port and a sealing cover on the support plates, an installation plate rotatably mounted inside the reaction tank, a stirring rod fixed on the installation plate, a motor fixed on the side of the reaction tank, and the installation plate fixedly connected to the output shaft of the motor.

[0006] Preferably, the crushing mechanism includes a cutting roller rotatably mounted on a feeding hopper, a motor is fixedly mounted on the feeding hopper, and the cutting roller is fixedly connected to the output shaft of the motor.

[0007] Preferably, the feeding hopper is cone-shaped, and the inner wall of the feeding hopper is equipped with a cutting blade that works in conjunction with the cutting roller.

[0008] Preferably, stirring rod 2 is provided on both sides of stirring rod 1, and stirring rod 2 is rotatably mounted on mounting plate. The mounting plate is provided with a drive mechanism for driving stirring rod 2 to rotate.

[0009] Preferably, the driving mechanism includes a gear fixedly mounted on the top end of the stirring rod, and an internal gear ring that meshes with the gear is fixed on the inner wall of the reaction tank.

[0010] Preferably, both support plates are provided with a flipping mechanism, and the flipping mechanism is located on the side of the fixed sleeve. The flipping mechanism includes a motor three fixedly installed on the side of the support plate. The output shaft of the motor three is fixedly installed with a rotating rod, and a slider is rotatably installed at the end of the rotating rod. The slider is slidably disposed on the reaction tank.

[0011] Preferably, a guide rod is fixed to the side of the reaction vessel, and the slider is slidably disposed on the outer surface of the guide rod.

[0012] Preferably, a scraper is fixed on the mounting plate, and the outer surface of the scraper is in contact with the inner wall of the reaction vessel.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by setting up a crushing mechanism, a mounting plate, a second motor and a first stirring rod, the crushing mechanism can crush the added ore, so that the ore and the solution can come into more complete contact. The second motor drives the mounting plate to rotate, and the rotation of the mounting plate drives the first stirring rod to rotate synchronously, thereby stirring and mixing the ore and liquid inside the reaction tank, improving the leaching reaction efficiency.

[0015] 2. In this utility model, by setting a motor and a cutting roller, the motor drives the cutting roller to rotate, which can quickly crush the added ore, making it easier to react with the solution later. The cutting blade and the cutting roller work together to crush the ore. At the same time, since the feeding hopper is set as a cone shape, the ore can be crushed step by step, which can facilitate the crushing of larger ores and avoid the problem of ore blockage. It also reduces the pressure on the crushing blade and the crushing roller.

[0016] 3. In this utility model, by setting a driving mechanism and a stirring rod two, the mounting plate drives the stirring rod one to rotate, and at the same time, the driving mechanism drives the stirring rod two to rotate synchronously. The stirring rod two is used to further stir and mix the liquid and ore inside the reaction tank, which helps the ore and solution to mix better and improves the reaction efficiency.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a mineral slurry leaching and dissolving reaction device, comprising a base 1, two support plates 2 fixed on the upper surface of the base 1, a reaction tank 4 disposed between the two support plates 2, a fixing sleeve 3 fixed on the outer surface of the reaction tank 4, and the fixing sleeve 3 rotatably mounted on the support plates 2, a feeding hopper 5 mounted on the support plates 2, the feeding hopper 5 having a feeding port and a feeding cover, a crushing mechanism disposed inside the feeding hopper 5, a discharge port on the support plates 2 with a sealing cover, and a device for rotatably mounting the reaction tank 4. Mounting plate 8 has a stirring rod 9 fixed on it, and motor 10 is fixed on the side of reaction tank 4. Mounting plate 8 is fixedly connected to the output shaft of motor 10. By setting up a crushing mechanism, mounting plate 8, motor 10 and stirring rod 9, the crushing mechanism can crush the added ore, so that the ore and solution can come into more complete contact. Motor 10 drives mounting plate 8 to rotate, and the rotation of mounting plate 8 drives stirring rod 9 to rotate synchronously, thereby stirring and mixing the ore and liquid inside reaction tank 4 and improving the leaching reaction efficiency.

[0025] Reference Figure 3The crushing mechanism includes a cutting roller 6 rotatably mounted on the feeding hopper 5. A motor 7 is fixed on the feeding hopper 5. The cutting roller 6 is fixedly connected to the output shaft of the motor 7. By setting up the motor 7 and the cutting roller 6, the motor 7 drives the cutting roller 6 to rotate, which can quickly crush the added ore, facilitating subsequent reaction with the solution. The motor 14 drives the rotating rod 17 to rotate, and the rotating rod 17 drives the slider 16 to rotate synchronously. The slider 16 drives the reaction tank 4 to rotate up and down, thereby causing the reaction tank 4 to drive the internal solution and ore to rotate and mix synchronously. This can effectively mix the solution and ore at the bottom and corners of the reaction tank 4, realizing the leaching of the ore.

[0026] Reference Figure 3 The feeding hopper 5 is set in a cone shape, and the inner wall of the feeding hopper 5 is equipped with a cutting blade that works in conjunction with the cutting roller 6. The cutting blade and the cutting roller 6 work together to crush the ore. At the same time, because the feeding hopper 5 is set in a cone shape, the ore can be crushed step by step, which can facilitate the crushing of larger ore, avoid the problem of ore blockage, and reduce the pressure on the crushing blade and crushing roller.

[0027] Reference Figure 3 and Figure 4 Both sides of the stirring rod 9 are provided with stirring rods 11. The stirring rods 11 are rotatably mounted on the mounting plate 8. The mounting plate 8 is provided with a drive mechanism for driving the stirring rods 11 to rotate. By setting the drive mechanism and the stirring rods 11, the mounting plate 8 can drive the stirring rod 9 to rotate while the stirring rods 11 rotate synchronously through the drive mechanism. The stirring rods 11 further stir and mix the liquid and ore inside the reaction tank 4, helping the ore and solution to mix better and improving the reaction efficiency.

[0028] Reference Figure 3 and Figure 4 The driving mechanism includes a gear 12 fixedly installed at the top of the stirring rod 11. An internal gear ring 13 that meshes with the gear 12 is fixed on the inner wall of the reaction tank 4. By setting the gear 12 and the internal gear ring 13, the mounting plate 8 drives the stirring rod 11 to rotate, and the stirring rod 11 drives the gear 12 to rotate with the mounting plate 8. At the same time, the gear 12 meshes with the internal gear ring 13, driving the gear 12 to drive the stirring rod 11 to rotate synchronously. This allows the stirring rod 11 to rotate and stir while following the rotation of the mounting plate 8, and also allows the stirring rod 11 to rotate on its own to stir, further improving the mixing effect.

[0029] Reference Figure 1 and Figure 2Both support plates 2 are equipped with a flipping mechanism, which is located on the side of the fixed sleeve 3. The flipping mechanism includes a motor 3 14 fixedly installed on the side of the support plate 2. A rotating rod 17 is fixedly installed on the output shaft of the motor 3 14. A slider 16 is rotatably installed at the end of the rotating rod 17. The slider 16 is slidably set on the reaction tank 4. By setting the motor 3 14, the rotating rod 17 and the slider 16, the motor 3 14 drives the rotating rod 17 to rotate. The rotation of the rotating rod 17 drives the slider 16 to rotate synchronously. At the same time, the slider 16 drives the reaction tank 4 to flip up and down, thereby causing the reaction tank 4 to drive the internal solution and ore to flip and mix synchronously. This can effectively mix the solution and ore at the bottom and corners of the reaction tank 4, and improve the fullness of the solution and ore mixing reaction.

[0030] Reference Figure 2 A guide rod 15 is fixed to the side of the reaction vessel 4, and a slider 16 is slidably disposed on the outer surface of the guide rod 15. By setting the guide rod 15, the slider 16 can be limited and guided, avoiding the problem of deviation and shaking during operation and improving stability.

[0031] Reference Figure 4 A scraper 18 is fixed on the mounting plate 8, and the outer surface of the scraper 18 is in contact with the inner wall of the reaction tank 4. By setting the scraper 18, the mounting plate 8 rotates and drives the scraper 18 to rotate synchronously. The scraper 18 can clean the inner wall of the reaction tank 4, preventing ore and solution residue from remaining on the inner wall of the reaction tank 4.

[0032] Working principle: The system controls the start of motors 7, 10, and 14 to add ore and solution into the feeding hopper 5. Motor 7 drives the cutting roller 6 to rotate, rapidly crushing the added ore. Motor 10 drives the mounting plate 8 to rotate, which in turn drives the stirring rod 9 to rotate synchronously. As the mounting plate 8 drives the stirring rod 11 to rotate, the stirring rod 11 drives the gear 12 to rotate with the mounting plate 8. Simultaneously, as the gear 12 meshes with the internal gear ring 13, it drives the stirring rod 11 to rotate synchronously. This allows the stirring rod 11 to rotate and stir simultaneously with the mounting plate 8, while also rotating on its own axis to ensure full contact between the ore and the solution.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
