Description

Technical Field

[0001] This utility model relates to the field of lead-zinc ore processing technology, and in particular to a lead-zinc ore grinding concentration control device. Background Technology

[0002] The lead-zinc ore grinding concentration control device is a key piece of equipment in the lead-zinc ore beneficiation process for precisely controlling the slurry concentration during the grinding stage. By adjusting parameters such as water replenishment and slurry flow rate, it stabilizes the grinding concentration within the optimal range to ensure grinding efficiency and subsequent beneficiation effects, playing a crucial role in improving the grade and recovery rate of lead-zinc ore concentrate. In the installation of existing devices, due to their relatively traditional structural design, the connection of the main pipeline generally relies on multiple sets of bolts for fixation. This connection method has significant drawbacks: firstly, the installation of each component requires the alignment and tightening of dozens or even hundreds of bolts, demanding not only extremely high precision control from the installers but also consuming a significant amount of time; secondly, repeated disassembly and tightening of bolts can easily cause thread wear and component positioning deviations, potentially leading to slurry leakage and loosening of control components after long-term use, affecting the stability of concentration control. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing technology has the disadvantages of not only consuming a lot of time during installation, but also causing thread wear and component positioning deviation due to repeated disassembly and tightening of bolts. After long-term use, slurry leakage may occur, affecting the stability of concentration control. To this end, we propose a lead-zinc ore grinding concentration control device.

[0004] To achieve the above objectives, this application adopts the following technical solution: a lead-zinc ore grinding concentration control device, comprising a concentration control valve, with feed pipes fixedly arranged on both sides of the concentration control valve, an external connecting pipe provided at the end of the feed pipe away from the concentration control valve, a fixing ring fixedly connected at the end of the external connecting pipe near the feed pipe, a fixing groove formed on the outer wall of the end of the feed pipe near the external connecting pipe, the inner diameter of the fixing ring matching that of the fixing groove, a first magnetic block fixedly connected to the outer wall of the fixing ring, and a second magnetic block fixedly connected to the bottom of the cavity of the fixing groove, the first magnetic block and the second magnetic block being attracted by opposite poles.

[0005] Furthermore, when the fixing ring is fully engaged with the inner wall of the fixing groove, the first magnetic block adheres to the second magnetic block, successfully replacing the traditional bolt connection, greatly shortening the installation time required, and the magnetic adhesion method avoids the wear problem common in threaded connections.

[0006] Furthermore, a separation component is provided at the upper end of the feed pipe. The separation component is used to separate the first magnetic block and the second magnetic block, which simplifies the disassembly process, makes equipment maintenance more convenient and efficient, and reduces downtime caused by maintenance.

[0007] Furthermore, the separation assembly includes a control block rotatably connected to the upper wall of the feed pipe, and a movable groove formed on the upper wall of the feed pipe. A threaded rod is fixedly connected to the lower end of the control block, and a movable rod is threadedly connected to the outer wall of the threaded rod. A separation rod is fixedly connected to the lower end of the movable rod. Precise control of the separation force is achieved through threaded transmission. The operator can flexibly adjust the rotation force according to the magnitude of the magnetic attraction force, avoiding violent operation during the separation process, effectively protecting the integrity of the magnetic block and the connecting structure, and ensuring that the separation process is stable and controllable.

[0008] Furthermore, the separating rod has a conical structure and is made of brass, which significantly improves the separation efficiency and reduces the loss caused by friction during the separation of the magnetic blocks. The non-magnetic properties of brass ensure that the separation process does not affect the subsequent adsorption performance of the magnetic blocks.

[0009] Furthermore, both sides of the movable rod are fixedly connected to slider bodies, and both sides of the inner wall of the movable groove are provided with sliding groove bodies. The slider bodies are slidably connected to the inner walls of the sliding groove bodies, which ensures the straightness of the lifting trajectory of the movable rod, significantly improves the alignment accuracy of the separating rod, avoids component jamming or damage caused by the offset of the separating rod, and enhances the stability and reliability of the separation assembly operation.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] In this invention, the engagement of the fixing ring and the fixing groove provides a basic positioning for the magnetic connection. The magnetic force of the first magnetic block and the second magnetic block achieves reliable fixing and sealing. The separation component achieves controllable release of the magnetic force through threaded transmission and guide structure. All components work together to build a complete working cycle of positioning, magnetic attraction, sealing and separation. This solves the problems that not only consume a lot of time during installation, but also that repeated disassembly and tightening of bolts can easily cause thread wear and component positioning deviation, and may lead to slurry leakage after long-term use, affecting the stability of concentration control.

[0018] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0019] Reference Figures 1-4 As shown, in order to solve the problems that not only consume a lot of labor time during installation, but also that repeated disassembly and tightening of bolts can easily cause thread wear, component positioning deviation, and slurry leakage after long-term use, affecting the stability of concentration control, the following preferred technical solutions are provided:

[0020] A lead-zinc ore grinding concentration control device includes a concentration control valve 1 and feed pipes 2 fixedly installed on both sides of the concentration control valve 1. An external connecting pipe 3 is installed at the end of the feed pipe 2 furthest from the concentration control valve 1. A fixing ring 4 is fixedly connected to the end of the external connecting pipe 3 closest to the feed pipe 2. A fixing groove 5 is formed on the outer wall of the end of the feed pipe 2 closest to the external connecting pipe 3. In this device, the concentration control valve 1 serves as the core control unit, capable of precisely adjusting the concentration of the slurry. The feed pipes 2 on both sides are responsible for transporting the slurry to be processed to the concentration control valve 1, or transporting the slurry after concentration adjustment to the next stage. The end of the feed pipe 2 and the external connecting pipe 3 are connected through the interlocking of the fixing ring 4 and the fixing groove 5. This interlocking structure provides initial positioning and support for the connection between the two. The inner diameter of the fixing ring 4 matches that of the fixing groove 5. The outer wall of the fixing ring 4 is fixedly connected to the first magnetic block 6, and the bottom of the cavity of the fixing groove 5 is fixedly connected to the second magnetic block 7. The first magnetic block 6 and the second magnetic block 7 are attracted by opposite poles. The magnetic attraction between the fixing ring 4 and the fixing groove 5 replaces the traditional bolt connection method, effectively reducing the wear of parts caused by repeated disassembly.

[0021] When the retaining ring 4 is fully engaged with the inner wall of the retaining groove 5, the first magnetic block 6 adheres to the second magnetic block 7. The inner diameters of the retaining ring 4 and the retaining groove 5 are precisely machined to ensure that there is no radial gap after they are engaged, laying the foundation for the stability of the connection. The first magnetic block 6 and the second magnetic block 7 adopt an opposite attraction design. When the retaining ring 4 is fully engaged with the retaining groove 5, the two magnetic blocks adhere tightly under the action of magnetic force, generating a strong magnetic force to firmly fix the feed pipe 2 and the outer pipe 3 together. At the same time, the contact surface of the magnetic blocks forms the first sealing barrier, which can effectively block the path of slurry leakage and prevent slurry from seeping out from the connection gap. It successfully replaces the traditional bolt connection, greatly shortening the installation time required; the magnetic adhesion method avoids the wear problems common in threaded connections, significantly enhances the sealing performance of the connection, reduces the risk of slurry leakage from the source, and ensures the stability of slurry concentration control.

[0022] A separation component 8 is installed at the upper end of the feed pipe 2. The main function of the separation component 8 is to separate the first magnetic block 6 and the second magnetic block 7. When the equipment needs to be disassembled for maintenance or component replacement, directly pulling the feed pipe 2 and the outer connecting pipe 3 may cause deformation of the components or damage to the magnetic blocks. However, the separation component 8 can overcome the magnetic attraction by applying a controllable mechanical force, allowing the first magnetic block 6 and the second magnetic block 7 to separate smoothly. This achieves non-destructive separation of the magnetic connection, ensures the reusability of the components, and reduces the maintenance cost of the equipment. At the same time, it simplifies the disassembly process, making equipment maintenance more convenient and efficient, and reducing downtime caused by maintenance.

[0023] The separation assembly 8 includes a control block 81 rotatably connected to the upper wall of the feed pipe 2, and a movable groove 82 formed on the upper wall of the feed pipe 2. A threaded rod 83 is fixedly connected to the lower end of the control block 81, and a movable rod 84 is threadedly connected to the outer wall of the threaded rod 83. A separation rod 85 is fixedly connected to the lower end of the movable rod 84. When it is necessary to separate the first magnetic block 6 and the second magnetic block 7, the operator rotates the control block 81, which drives the threaded rod 83 to rotate together. Since the movable rod 84 is threadedly connected to the threaded rod 83, and the movable rod 84 is limited by the movable groove 82, it cannot rotate with the threaded rod 83. Therefore, the rotational motion of the threaded rod 83 is converted into the vertical lifting motion of the movable rod 84. When the movable rod 84 descends, it drives the separating rod 85 to move downward and insert it between the first magnetic block 6 and the second magnetic block 7. The two magnetic blocks are separated by wedge force. The separation force is precisely controlled by the threaded transmission. The operator can flexibly adjust the rotation force according to the magnitude of the magnetic attraction force, avoiding violent operation during the separation process, effectively protecting the integrity of the magnetic blocks and the connecting structure, and ensuring that the separation process is stable and controllable.

[0024] The separating rod 85 has a conical structure and is made of brass. The conical design allows the lower tip of the separating rod 85 to easily insert into the tiny gap between the first magnetic block 6 and the second magnetic block 7. As the movable rod 84 continues to descend, the conical surface of the separating rod 85 gradually contacts the two magnetic blocks, converting the vertical force into a horizontal separation force, thus gradually separating the two magnetic blocks and significantly reducing the resistance required for separation. Brass is non-magnetic and will not interfere with the magnetic force between the first magnetic block 6 and the second magnetic block 7, ensuring the normal adsorption performance of the magnetic blocks. At the same time, brass has high strength and good wear resistance, which can withstand long-term repeated separation operations. This significantly improves separation efficiency and reduces wear caused by friction during magnetic block separation; the non-magnetic nature of brass ensures that the separation process does not affect the subsequent adsorption performance of the magnetic blocks, extending their service life.

[0025] Both sides of the movable rod 84 are fixedly connected to slider bodies 86, and both sides of the inner wall of the movable groove 82 are provided with sliding groove bodies 87, with the slider bodies 86 slidably connected to the inner walls of the sliding groove bodies 87. When the movable rod 84 moves up and down under the drive of the threaded rod 83, the slider bodies 86 slide synchronously along the sliding groove bodies 87, providing precise vertical guidance and constraint for the movement of the movable rod 84, effectively preventing the movable rod 84 from rotating with the threaded rod 83, and ensuring that the separating rod 85 can always be accurately inserted into the gap between the first magnetic block 6 and the second magnetic block 7 along the axial direction. This ensures the straightness of the lifting trajectory of the movable rod 84, significantly improves the alignment accuracy of the separating rod 85, avoids component jamming or damage caused by the offset of the separating rod 85, and enhances the stability and reliability of the separation assembly 8.

[0026] Specifically, the concentration control valve 1, as the core control unit, controls the slurry concentration by adjusting its own opening. The feed pipes 2 on both sides of the valve are responsible for slurry transportation, and their ends need to be connected to the external pipe 3 to form a complete transportation channel. During installation, the fixing ring 4 at the end of the external pipe 3 is aligned with the fixing groove 5 on the outer wall of the feed pipe 2 and pushed in axially. The inner diameter of the fixing ring 4 and the fixing groove 5 are precisely matched to form radial positioning and avoid connection misalignment. When the fixing ring 4 is fully inserted into the fixing groove 5, the first magnetic block 6 on the outer wall of the fixing ring 4 and the second magnetic block 7 at the bottom of the cavity of the fixing groove 5 are tightly attached due to the attraction of opposite poles, generating a continuous magnetic force to firmly lock the two pipes together. At the same time, the contact surface of the magnetic blocks forms an annular sealing strip to block the slurry leakage path and complete the rapid installation.

[0027] When disassembly and maintenance are required, the operator rotates the control block 81 on the upper wall of the feed pipe 2, which drives the threaded rod 83 fixed at the lower end to rotate synchronously. Since the movable rod 84 is threadedly connected to the threaded rod 83, and the slider body 86 on both sides of the movable rod 84 slides along the slide groove body 87 on the inner wall of the movable groove 82, the rotational motion of the threaded rod 83 is converted into the vertical downward motion of the movable rod 84. The separation rod 85 (conical brass component) at the lower end of the movable rod 84 moves down accordingly. The tip first inserts into the contact gap between the first magnetic block 6 and the second magnetic block 7. As it continues to descend, the conical surface converts the vertical pressure into a horizontal separation force, gradually opening the two magnetic blocks until the magnetic force is overcome and separation is completed, avoiding damage to components caused by violent disassembly.

[0028] Throughout the process, the engagement of the fixing ring 4 and the fixing groove 5 provides a basic positioning for the magnetic connection. The magnetic force of the first magnetic block 6 and the second magnetic block 7 achieves reliable fixation and sealing. The separation component 8 achieves controllable release of the magnetic force through threaded transmission and guide structure. All components work together to build a complete working cycle of positioning, magnetic attraction, sealing and separation. This solves the problems that not only consume a lot of time during installation, but also that repeated disassembly and tightening of bolts can easily cause thread wear, component positioning deviation, and slurry leakage after long-term use, affecting the stability of concentration control.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
