Description

Technical Field

[0001] This utility model relates to the field of zinc roasting leaching technology, specifically to a device for clearing and unblocking crystallization of wet zinc smelting electrolyte. Background Technology

[0002] Hydrometallurgical zinc refining is the mainstream technology in modern zinc smelting. Through core steps such as leaching, purification, electrolysis, and casting, zinc-containing raw materials (zinc calcined sand) are converted into high-purity metallic zinc. It has advantages such as high recovery rate, high product purity, and environmental friendliness. The essence of hydrometallurgical zinc refining is to use chemical dissolution to convert zinc in solid zinc-containing raw materials into soluble zinc salts, then remove impurities through purification, and finally reduce zinc ions to metallic zinc through electrolysis.

[0003] During the leaching process, due to the selective action of dilute sulfuric acid leaching agent, zinc in zinc calcined sand will dissolve into the solution. However, the solution usually contains calcium and magnesium ions, which will crystallize in the conveying pipeline, causing pipeline blockage, thereby affecting the normal use of the conveying pipeline and the continuity of the production process.

[0004] Currently, we mainly use manual steel pipe dredging and hammering to deal with these problems. However, in actual operation, due to the long length of the conveying pipeline, the steel pipe cannot be guaranteed to be coaxial with the conveying pipeline during the dredging process. As a result, the steel pipe often bends due to its own weight, which inevitably damages the conveying pipeline during repeated dredging. In addition, the steel pipe is heavy, which also wastes manpower in the whole dredging process. Utility Model Content

[0005] The purpose of this invention is to provide a device for clearing and unblocking the crystallization of zinc electrolyte in wet zinc smelting.

[0006] This utility model is implemented by the following technical solution: a wet zinc smelting electrolyte crystallization unblocking device, which includes a lifting support, a motor, a connecting rod group, a cutting tool, and a guiding device; The bottom end of the lifting bracket is provided with a pulley, the top end of the lifting bracket is fixed with the motor, the output shaft of the motor is fixed with a first screw, and the first screw is connected to the cutting tool through a connecting rod assembly; The outer wall of the connecting rod assembly is fitted with the guiding device, which includes a guide ring, a positioning ring, and a pipe clamp. The inner ring of the guide ring is fitted with the outer wall of the connecting rod assembly through a bearing. The side wall of the guide ring is fixed with the positioning ring that matches the inner wall of the conveying pipe. The outer diameter of the guide ring is the same as the outer diameter of the conveying pipe, and the outer wall of the guide ring is fitted with the pipe clamp.

[0007] Furthermore, the cutting tool includes a protective sleeve, a cutting blade, and an outer ring. One end of the protective sleeve has an internal thread on its inner wall, and the other end of the protective sleeve has the outer ring. Multiple cutting blades are fixedly connected between the outer ring and the protective sleeve. Both ends of the cutting blade have arc-shaped cutting edges, and the straight cutting edge between two arc-shaped cutting edges has multiple teeth.

[0008] Furthermore, the connecting rod assembly includes multiple connecting rods connected in series. Each connecting rod includes a rod body and a second screw.

The second screw of the connecting rod is screwed to the internal thread end of the next adjacent connecting rod section, the internal thread end of the first connecting rod section is screwed to the first screw, and the second screw of the last connecting rod section is screwed to the internal thread end of the protective sleeve.

[0009] Furthermore, the first screw and the second screw are respectively screwed with locking nuts, and the locking nuts abut against the internal thread end of the connecting rod or the internal thread end of the protective sleeve.

[0010] The advantages of this utility model are: with the cooperation of the lifting bracket, motor and cutting blade, the motor drives the connecting rod group to rotate, and the connecting rod group drives the cutting blade to rotate.

[0013] 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.

[0014] like Figure 1-3 As shown, the wet zinc smelting electrolyte crystallization unblocking device includes a lifting support 1, a motor 2, a connecting rod 4.1, a cutting blade 5, and a guiding device 9. The bottom end of the lifting support 1 is equipped with a pulley 7. Under the action of the pulley 7, the lifting support 1 can be moved easily. During the process of crushing the crystals in the conveying pipe 6, the lifting support 1 is pushed forward.

[0015] A motor 2 is fixed at the top of the lifting bracket 1. A first screw 3 is fixed to the output shaft of the motor 2. The first screw 3 is connected to the cutting tool 5 through a connecting rod assembly 4. Under the action of the motor 2, the connecting rod assembly 4 is driven to rotate. During the rotation of the connecting rod assembly 4, the cutting tool 5 is driven to rotate. During the rotation of the cutting tool 5 in the conveying pipe 6, the blockage crystals in the conveying pipe 6 are broken. After the breaking is completed, the normal conveying of the leachate solution in the subsequent conveying pipe 6 is ensured.

[0016] The outer wall of the connecting rod assembly 4 is fitted with a guide device 9. Under the action of the guide device 9, the cutting tool 5 and the connecting rod 4.1 are limited. When the conveying pipe 6 is long, multiple connecting rods 4.1 are required. Under the action of the guide device 9, the connecting rod assembly 4 is further supported, ensuring the concentricity of the connecting rod assembly 4 and the conveying pipe 6.

[0017] The guiding device 9 includes a guide ring 9.1, a positioning ring 9.2, and a clamp 9.3. The inner ring of the guide ring 9.1 is fitted with the outer wall of the connecting rod assembly 4 through a bearing 10 with a clearance, which reduces the forward force on the bearing 10 and limits the movement of the connecting rod assembly 4. The side wall of the guide ring 9.1 is fixed with a positioning ring 9.2 that matches the inner wall of the conveying pipe 6. The outer diameter of the guide ring 9.1 is the same as the outer diameter of the conveying pipe 6, and the outer wall of the guide ring 9.1 is provided with a clamp 9.3. With the help of the positioning ring 9.2, it is easy to install the guide ring 9.1 on the conveying pipe 6. The positioning ring 9.2 has the function of auxiliary support for the guide ring 9.1. With the help of the bearing 10, the forward pushing of the connecting rod assembly 4 is ensured, and the friction between the connecting rod assembly 4 and the inner ring of the guide ring 9.1 is reduced.

[0018] The cutting tool 5 includes a protective sleeve 5.1, a cutting blade 5.2, and an outer ring 5.3. One end of the protective sleeve 5.1 has an internal thread on its inner wall, and the other end of the protective sleeve 5.1 has an outer ring 5.3. Multiple cutting blades 5.2 are fixedly connected between the outer ring 5.3 and the protective sleeve 5.1. Both ends of the cutting blade 5.2 have arc-shaped cutting edges 5.2.1, and the straight cutting edge 5.2.2 between the two arc-shaped cutting edges 5.2.1 has multiple teeth 5.2.3. Under the action of the cutting blade 5.2, the crystals blocking the conveying pipe 6 are broken up, thus solving the problem of blockage in the conveying pipe 6.

[0019] The connecting rod assembly 4 includes multiple connecting rods 4.1 connected in series. Each connecting rod 4.1 includes a rod body 4.1.1 and a second screw 4.1.2. One end of the rod body 4.1.1 is fixed with the second screw 4.1.2, and the inner wall of the other end of the rod body 4.1.1 is provided with an internal thread. The second screw 4.1.2 of the connecting rod 4.1 is screwed to the internal thread end of the next adjacent connecting rod 4.1. The internal thread end of the first connecting rod 4.1 is screwed to the first screw 3. The second screw 4.1.2 of the last connecting rod 4.1 is screwed to the internal thread end of the sleeve 5.1.

[0020] The first screw 3 and the second screw 4.1.2 are respectively screwed with locking nuts 8. The locking nuts 8 abut against the internal thread end of the connecting rod 4.1 or the internal thread end of the protective sleeve 5.1. The function of the locking nuts 8 is to limit the position between the two adjacent connecting rods 4.1 and the protective sleeve 5.1, so as to facilitate disassembly.

[0021] The specific operation process of this embodiment is as follows: Close the valves at the inlet and outlet of the conveying pipeline 6, and then remove the end cap at one end of the conveying pipeline 6; The cutting tool 5 and the last section of the connecting rod 4.1 of the connecting rod assembly 4 are placed inside the conveying pipe 6. Then, a guide ring 9.1 is fitted onto the connecting rod 4.1. Under the action of the positioning ring 9.2, the guide ring 9.1 is installed and fixed to the conveying pipe 6 with the pipe clamp 9.3. Then, other connecting rods 4.1 are fixed in sequence at the end of the connecting rod 4.1 outside the guide ring 9.1, finally forming the connecting rod assembly 4. By adjusting the lifting bracket 1, the other end of the connecting rod assembly 4 is fixedly connected to the output shaft of the motor 2. At this time, the output shaft of the motor 2 and the axis of the conveying pipe 6 are parallel and placed in the same vertical plane. A certain gap is left between the cutting tool 5 and the inner wall of the conveying pipe 6, so as not to damage the conveying pipe 6 and extend the service life of the conveying pipe 6. Start motor 2 and push lifting bracket 1 forward, so that the blade of cutting tool 5 cuts and breaks the crystals as the motor 2 drives it to rotate, clearing the blockage until it is completely clear. During the clearing process, the crystals that are cleared will fall through the hollow area between the protective sleeve 5.1 and the outer ring 5.3 and fall to the back of the cutting tool 5. After the blockage is cleared, when the cutting tool 5 exits the conveying pipe 6, the guide device 9 is removed. Then, under the action of the outer ring 5.3, the large crystalline material accumulated at the bottom of the conveying pipe 6 can be scraped out of the conveying pipe 6. For small crystalline materials, during the normal conveying of the leaching solution in the later stage, the small crystalline materials will naturally dissolve due to the high temperature of the leaching solution, without affecting the conveying.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
