Abstract
Description
Technical Field
[0001] This utility model relates to the field of ore processing technology, and in particular to a zinc concentrate beneficiation device. Background Technology
[0002] As a key piece of equipment in the mineral processing field, the zinc concentrate beneficiation unit is responsible for the efficient enrichment and purification of zinc concentrate from zinc ore. Throughout the beneficiation process, the beneficiation unit undergoes a series of complex steps, including crushing, grinding, flotation, classification, and concentration filtration, with the aim of precisely separating zinc minerals from gangue minerals to ultimately produce a high-grade zinc concentrate product. The feed inlet and discharge outlet, as the core structures of this unit, play a decisive role in the beneficiation effectiveness and production efficiency.
[0003] 1. The feeding system is responsible for uniformly feeding the zinc concentrate to be refined into the refining device. Its stability and feeding accuracy have an important impact on the refining effect.
[0004] 2. Mineral processing reaction tank: This is the core area for various mineral processing reactions. Different mineral processing processes separate impurities from zinc concentrate in this area through specific physical or chemical actions.
[0005] 3. A stirring device is installed inside the mineral processing reaction tank. It stirs the slurry to fully mix with various mineral processing reagents, thereby promoting the mineral processing reaction.
[0006] 4. Separation device, used to discharge the concentrate and tailings separated after the mineral processing reaction.
[0007] Currently, the industry has adopted various measures to improve the beneficiation effect of zinc concentrate. Some companies have adopted large-scale, high-efficiency crushers and mills to increase processing capacity; some manufacturers have improved zinc ore recovery rates by optimizing flotation reagent formulations and addition methods; and some companies have introduced advanced automated control systems to precisely control the beneficiation process.
[0008] However, existing zinc concentrate beneficiation equipment has significant drawbacks in the feeding and discharging stages. Traditional feed inlets are generally fixed at a single location, causing material to enter subsequent processing equipment, such as crushers or mills, only from a single fixed point. This fixed feeding mode easily leads to uneven material distribution within the equipment, resulting in localized accumulation or uneven loading. This prevents the material from being uniformly subjected to crushing and grinding operations, reducing equipment efficiency and shortening its lifespan due to excessive localized wear. Simultaneously, the discharge port size of existing equipment is mostly fixed, making it difficult to meet diverse production needs. When different particle sizes of zinc concentrate products are required, the fixed discharge port cannot effectively control the material flow within the equipment. The residence time and degree of crushing and grinding within the device can lead to inconsistent product particle size, and even breakage issues. When dealing with different production scales, a fixed discharge port makes it difficult to flexibly adjust the output per unit time, thus affecting the material handling capacity and production rhythm of the entire beneficiation unit. To address the above problems, this application proposes an innovative zinc concentrate beneficiation device. Through a feed port that can move back and forth in a straight line, uniform material distribution is achieved, ensuring that the material inside the equipment is evenly stressed. At the same time, it is equipped with a discharge port of flexible size to adapt to different production needs. Whether it is adjusting product particle size or controlling output, it can easily cope with the situation, thereby comprehensively improving the working efficiency, product quality and production flexibility of the beneficiation unit. Utility Model Content
[0009] To address the shortcomings of existing technologies, this utility model provides a zinc concentrate beneficiation device that solves the problem that traditional feed inlets are generally fixed at a certain position, causing materials to enter subsequent processing equipment, such as crushers or mills, only from a single fixed point. This fixed feeding mode easily leads to an imbalance in the distribution of materials within the equipment, resulting in local accumulation or uneven loading, making it impossible for materials within the equipment to undergo crushing, grinding, and other operations evenly.
[0010] To achieve the above objectives, this utility model provides the following technical solution:
[0011] A zinc concentrate beneficiation device includes a crusher, a connecting frame fixedly connected to the upper surface of the crusher, a feed hopper disposed above the connecting frame, connecting plates fixedly connected to both the front and rear sides of the feed hopper, a lead screw rotatably connected inside the connecting frame, a limit plate movably connected inside the feed hopper, limit blocks fixedly connected to the opposite surfaces of the two connecting plates, a connecting block fixedly connected to the left surface of the feed hopper, a limit post movably connected inside the connecting block, a return spring fixedly connected to the lower surface of the limit post, a servo motor fixedly connected to the left surface of the connecting frame, and the output shaft of the servo motor fixedly connected to the lead screw.
[0012] Preferably, the connecting frame has slots on both the front and rear sides, and the two slots are movably connected to the two limiting blocks respectively. The lead screw is set in the front slot of the two slots, and the front limiting block of the two limiting blocks is threadedly connected to the lead screw. The surface of the limiting plate has a set of round holes, and the set of round holes are movably connected to the limiting post.
[0013] Preferably, the upper surface of the connecting block is provided with a circular groove, the limiting post is movably sleeved with the circular groove, the circular groove is fixedly connected to the reset spring, and a push handle is fixedly connected to the annular side of the limiting post.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. When the lead screw rotates, the limiting block sleeved on it is subjected to the thread action and moves linearly back and forth. The movement of the limiting block will drive the fixed connecting plate to move together. At this time, the feed hopper fixed to the connecting plate also moves. When the feed hopper moves, the zinc ore particles in it can be evenly fed into the crusher, avoiding particle accumulation caused by the fixed feeding position. This allows the particles in the device to be evenly crushed and ground, improving the working efficiency and processing effect of the device.
[0016] 2. The limiting plate is inclined inside the feed hopper to facilitate the feeding of crushed stone particles. The size of the feed hopper's discharge port can be adjusted by moving and adjusting the limiting plate. When it is necessary to increase the output, the discharge port can be appropriately enlarged to allow the material to be discharged more smoothly and increase the processing volume per unit time. When it is necessary to reduce the output to meet specific production rhythm or quality control requirements, the discharge port can be narrowed to reduce the output. The adjustment is convenient and improves the overall flexibility. Attached Figure Description

[0023] This application provides a zinc concentrate beneficiation device that effectively solves the problem that traditional feed inlets are generally fixed in a certain position, causing materials to enter subsequent processing equipment, such as crushers or mills, only from a single fixed point. This fixed feeding mode easily leads to unbalanced material distribution within the equipment, resulting in local accumulation or uneven loading, making it impossible for materials to be uniformly subjected to crushing, grinding, and other operations. By using a feed inlet that can move back and forth in a straight line, uniform material distribution is achieved, ensuring that the materials within the equipment are evenly stressed. At the same time, it is equipped with a discharge port of flexible size to adapt to different production needs. Whether it is adjusting product particle size or controlling output, it can easily cope with the situation, thereby comprehensively improving the working efficiency, product quality, and production flexibility of the beneficiation device.
[0024] Example
[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that traditional feed inlets are generally fixed at a certain position, causing materials to enter subsequent processing equipment, such as crushers or grinding mills, only from a single fixed point. This fixed feeding mode easily leads to unbalanced material distribution within the equipment, resulting in local accumulation or uneven loading, making it impossible for materials within the equipment to uniformly undergo crushing, grinding, and other operations. The overall approach is as follows:
[0026] To address the problems existing in the prior art, this utility model provides a zinc concentrate beneficiation device, including a crusher 1. A connecting frame 2 is fixedly connected to the upper surface of the crusher 1, and a feed hopper 3 is arranged above the connecting frame 2. Connecting plates 4 are fixedly connected to both the front and rear sides of the feed hopper 3. A lead screw 6 is rotatably connected inside the connecting frame 2. A limit plate 9 is movably connected inside the feed hopper 3, and limit blocks 10 are fixedly connected to the opposite faces of the two connecting plates 4. A connecting block 7 is fixedly connected to the left surface of the feed hopper 3, and a limit post 13 is movably connected inside the connecting block 7. A return spring 15 is fixedly connected to the lower surface of the limit post 13. A servo motor 5 is fixedly connected to the left surface of the connecting frame 2, and the output shaft of the servo motor 5 is fixedly connected to the lead screw 6. During use, coarsely crushed zinc ore particles are fed into the crusher 1 through the feed hopper 3. The fed zinc ore particles are subjected to the high-speed rotating rotor inside the crusher 1. The impact force throws the zinc ore against the impact plate, where it is repeatedly crushed by repeated impacts between the impact plate and the rotor. Subsequent grinding operations further separate the zinc ore from the gangue minerals, enriching and purifying the zinc concentrate and creating conditions for subsequent beneficiation. Before crushing, the servo motor 5 is started, and its output shaft drives the fixed lead screw 6 to rotate. As the lead screw 6 rotates, the limiting block 10 fitted on it undergoes linear reciprocating motion due to the thread action. The movement of the limiting block 10 moves the fixed connecting plate 4, causing the feed hopper 3, which is fixed to the connecting plate 4, to move as well. This movement allows the zinc ore particles inside the feed hopper 3 to be evenly fed into the crusher 1, preventing particle accumulation caused by a fixed feed position. This ensures that the particles within the device are evenly subjected to crushing and grinding, improving the device's efficiency and processing effect.
[0027] The connecting frame 2 has slots 11 on both the front and rear sides. The two slots 11 are movably connected to the two limiting blocks 10 respectively. The screw rod 6 is set in the front slot 11. The front limiting block 10 is threadedly connected to the screw rod 6. The limiting plate 9 has a set of round holes 8 on its surface. The set of round holes 8 are movably connected to the limiting post 13. The connecting block 7 has a round groove 12 on its upper surface. The limiting post 13 is movably connected to the round groove 12. The round groove 12 is fixedly connected to the return spring 15. The limiting post 13 is fixedly connected to the annular side of the ring-shaped side. By pulling the push handle 14 downward, the fixed limiting post 13 is moved together. The movement compresses the return spring 15, at which point the limiting post 13 disengages from the set of round holes 8 on the limiting plate 9, opening the limit. At this point, the limiting plate 9 can move within the feeding hopper 3. The limiting plate 9 is designed to be inclined within the feeding hopper 3, facilitating the feeding of crushed stone particles. The size of the discharge port of the feeding hopper 3 can be adjusted by moving and adjusting the limiting plate 9. When it is necessary to increase the output, the discharge port can be appropriately enlarged to allow the material to be discharged more smoothly and increase the processing capacity per unit time. When it is necessary to reduce the output to meet specific production rhythm or quality control requirements, the discharge port can be narrowed to reduce the output. The adjustment is convenient and improves the overall flexibility.

[0033] Servo motor 5: As a power source, it is fixed on the left surface of the connecting frame 2, and its output shaft is fixedly connected to the lead screw 6; after starting, it drives the lead screw 6 to rotate, providing power for the linear reciprocating movement of the feed hopper 3, controlling the movement of the feed hopper 3, and ensuring uniform feeding;
[0034] Lead screw 6: Rotatably connected in the connecting frame 2, and threadedly connected to the limit block 10, when rotated by the servo motor 5, it causes the limit block 10 to generate linear reciprocating motion, thereby driving the connecting plate 4 and the feed hopper 3 to move. It is a key transmission component for achieving uniform material distribution in the feed hopper 3.
[0035] Connecting block 7: Fixed on the left surface of the feed hopper 3, used to install the limiting post 13 and the return spring 15, and cooperates with the limiting plate 9. The movement of the limiting post 13 controls the limiting plate 9, thereby realizing the adjustment of the size of the feed hopper 3 outlet.
[0036] Round hole 8: It is opened on the surface of the limiting plate 9 and is movably connected with the limiting post 13; when the limiting post 13 is engaged with the round hole 8, the limiting plate 9 is fixed; when the limiting post 13 is disengaged from the round hole 8, the limiting plate 9 can move, thereby controlling the size of the discharge port of the feed hopper 3.
[0037] Limiting plate 9: It is movably connected inside the feed hopper 3 and is designed with an inclination to facilitate material feeding; the size of the discharge port of the feed hopper 3 can be adjusted by moving it to meet different production needs and improve the production flexibility of the device;
[0038] Limiting block 10: Fixed on the opposite side of connecting plate 4, one of which is threadedly connected to lead screw 6; when lead screw 6 rotates, limiting block 10 makes linear reciprocating motion, driving connecting plate 4 and feed hopper 3 to move, ensuring that feed hopper 3 distributes material evenly;
[0039] Slot 11: It is opened on the front and rear sides of the connecting frame 2 and is movably connected to the limit block 10. It guides and limits the movement of the limit block 10, ensuring that the limit block 10 moves back and forth in a straight line within the specified trajectory, thereby ensuring the stable movement of the feed hopper 3.
[0040] Circular groove 12: It is formed on the upper surface of the connecting block 7, movably sleeved with the limiting post 13 and fixedly connected with the return spring 15; it provides installation space and movement track for the limiting post 13, and at the same time, in conjunction with the return spring 15, realizes the reset control of the limiting post 13;
[0041] Limiting post 13: It is movably connected inside the connecting block 7, and its lower surface is connected to the return spring 15; by pulling the push handle 14, the limiting post 13 can be moved to engage or disengage with the round hole 8 on the limiting plate 9, thereby controlling the movement of the limiting plate 9 and adjusting the size of the discharge port of the feed hopper 3.
[0042] Push handle 14: Fixed to the annular side of the limiting post 13, making it convenient for the operator to manually pull the limiting post 13; by pulling the push handle 14, the return spring 15 is compressed, so that the limiting post 13 is disengaged from the limiting plate 9, so as to adjust the position of the limiting plate 9 and adjust the size of the discharge port of the feed hopper 3.
[0043] Reset spring 15: Fixed between the lower surface of the limit post 13 and the circular groove 12 of the connecting block 7. When the push handle 14 is pulled to move the limit post 13, the reset spring 15 provides elastic force so that the limit post 13 returns to its original position when it is not subjected to external force, and re-engages with the limit plate 9 to fix the position of the limit plate 9.
[0044] Working principle:
[0045] During operation, coarsely crushed zinc ore particles are fed into crusher 1 through feed hopper 3. The particles are impacted by the high-speed rotating rotor within crusher 1 and thrown against the impact plate. They are then repeatedly crushed by impact between the impact plate and the rotor. Subsequent grinding operations further separate the zinc ore from the gangue minerals, achieving enrichment and purification of the zinc concentrate, thus creating conditions for subsequent beneficiation operations. Before crushing, the output shaft of servo motor 5 drives a fixed lead screw 6 to rotate. As the lead screw 6 rotates, the limiting block 10 fitted onto it undergoes linear reciprocating motion due to the threaded action. The movement of the limiting block 10 moves the fixed connecting plate 4, causing the feed hopper 3, which is fixed to the connecting plate 4, to move as well. This movement of the feed hopper 3 ensures that the zinc ore particles are evenly distributed into crusher 1, preventing uneven feeding due to variations in feed position. The fixed position prevents particle accumulation, allowing the particles inside the device to be uniformly crushed and ground, thus improving the device's efficiency and processing effect. Pulling down the push handle 14 moves the fixed limiting post 13, compressing the return spring 15. At this time, the limiting post 13 disengages from the set of round holes 8 on the limiting plate 9, opening the limit. The limiting plate 9 can then move within the feed hopper 3. The limiting plate 9 is designed to be inclined within the feed hopper 3, facilitating the feeding of crushed stone particles. The size of the discharge port of the feed hopper 3 can be adjusted by moving and adjusting the limiting plate 9. When it is necessary to increase the output, the discharge port can be appropriately enlarged to allow the material to be discharged more smoothly and increase the processing capacity per unit time. When it is necessary to reduce the output to meet specific production rhythms or quality control requirements, the discharge port can be narrowed to reduce the output. The adjustment is convenient and improves the overall flexibility.
[0046] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
