Description

Technical Field

[0001] This invention relates to the field of zinc smelting concentration separation technology, and more specifically, to a buffer flow stabilization and swirl separation system for zinc smelting concentration underflow. Background Technology

[0002] In the hydrometallurgical zinc smelting process, the buffer and stabilization system for the thickener underflow is a crucial piece of equipment connecting the thickener to subsequent processes. Its core function is to perform solid-liquid separation and flow stabilization on the high-concentration slurry discharged from the thickener, providing high-quality, balanced material for subsequent processes such as filtration, grinding, and leaching. Therefore, the operational stability and processing efficiency of this system directly affect the overall capacity and product quality of the hydrometallurgical zinc smelting production line. This system typically consists of a buffer and stabilization unit and a cyclone separation unit. The buffer and stabilization unit reduces turbulent fluctuations in the slurry, while the cyclone separation unit utilizes centrifugal force to achieve efficient solid-liquid separation, making it an indispensable and vital link in the hydrometallurgical zinc smelting process. However, in actual industrial applications, this type of system faces severe challenges from the complex operating conditions of zinc smelting. The slurry in the zinc smelting process not only has high flow velocity characteristics but is also rich in corrosive chemical components. Prolonged exposure to this high-velocity, highly corrosive environment can easily cause bolts and nuts at the connection points of various system components to lock up. This locking problem stems from multiple factors, including the erosion of threaded connections by corrosive media, thread wear caused by vibration from high-velocity fluids, and oxidation and adhesion after long-term use. The locking phenomenon not only significantly increases the difficulty of equipment maintenance, requiring workers to spend considerable time and manpower disassembling and repairing components, but also makes it difficult to disassemble and repair equipment in a timely manner during sudden malfunctions. This leads to prolonged production line downtime, production schedule disruptions, and other problems, severely impacting the stability, reliability, and economy of the entire zinc smelting system. Furthermore, the existing support structure design of some systems is inadequate. Under the impact of high-velocity fluids and equipment vibrations, deformation of connection points and overall equipment shaking can easily occur, further exacerbating system instability and hindering the improvement of production efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the problem that the high flow rate and highly corrosive environment of the fluid in a current buffer stabilization and cyclone separation system for thick underflow in zinc smelting can cause bolts and nuts to lock up during prolonged use. This locking up not only increases the difficulty of equipment maintenance but also leads to equipment failure due to the inability to disassemble in a timely manner, thus affecting the stability and reliability of the entire system. The invention provides a buffer stabilization and cyclone separation system for thick underflow in zinc smelting to solve the aforementioned problems.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0005] The present invention is as follows: a buffer flow stabilization and cyclone separation system for thick underflow in zinc smelting, comprising a buffer flow stabilization chamber, a connecting mechanism provided on the outer side of the buffer flow stabilization chamber, a supporting mechanism provided on the outer side of the connecting mechanism, and a cyclone separator fixedly connected to the outer side of the connecting mechanism;

[0006] The connecting mechanism includes a conveying pipe fixedly connected to the outside of the buffer flow stabilizing chamber. A connecting plate is fixedly connected to the outside of the conveying pipe. A sliding column is slidably connected inside the connecting plate. A limit ring is fixedly connected to one side of the outer side of the sliding column. A docking block is slidably connected to the outside of the sliding column. A docking groove is opened on the top of the docking block. A locking component is installed inside the docking block. A limit component is installed inside the docking groove.

[0007] As a preferred embodiment of the present invention, the locking assembly includes a bolt threadedly connected inside the connecting disc, a nut slidably connected inside the mating block, and the external thread of the bolt connected inside the nut.

[0008] As a preferred technical solution of the present invention, the limiting component includes a support column slidably connected inside the docking block, a locking column slidably connected inside the docking block, and a connecting plate fixedly connected to the top of the locking column.

[0009] As a preferred embodiment of the present invention, the outer side of the limiting ring is closer to the conveying pipe, and the outer side of the docking block is farther away from the limiting ring.

[0010] As a preferred embodiment of the present invention, the support mechanism includes two support rings fixedly connected to the outside of the conveying pipe, and a connecting plate is fixedly connected to the bottom of the two support rings.

[0011] As a preferred technical solution of the present invention, a base plate is fixedly connected to the bottom of the connecting plate, and a support plate is fixedly connected to the outside of the conveying pipe, that is, the side close to the connecting plate.

[0012] As a preferred embodiment of the present invention, a docking plate is fixedly connected to the top of the support plate, and a connecting ring is fixedly connected to the outside of the cyclone separator.

[0013] As a preferred technical solution of the present invention, the outer sides of the base plate are respectively fixedly connected to the outer adjacent sides of the support plate and the connecting ring, and the outer side of the connecting ring is located at the bottom of the connecting plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] Optimized connection design reduces maintenance costs and improves operational reliability: The connection mechanism of this invention adopts a bolt and nut locking method, which not only ensures high stability of the connection between the conveying pipe, the docking block, and the hydrocyclone separator, meeting the connection strength requirements under high flow rate conditions in zinc smelting, but also allows the nut to slide flexibly within the docking block by reserving sliding space, effectively avoiding the nut locking problem caused by corrosion, vibration, and other factors in traditional connection structures. This innovative design greatly simplifies the disassembly and assembly process of the equipment. When performing maintenance, repair, or component replacement, the staff can quickly disassemble the bolts and nuts, significantly reducing the difficulty and labor intensity of maintenance operations, reducing the time and labor costs required for equipment maintenance, and shortening the production line downtime caused by maintenance, thereby improving production continuity. Furthermore, the limiting components in the connecting mechanism, through the synergistic action of the support column and the locking column, further enhance the installation stability of the docking block. The locking column penetrates the interior of the docking block and the sliding column, forming a double limiting mechanism. This effectively prevents the docking block from sliding or shifting due to fluid impact, vibration, or other factors during equipment operation, significantly improving the reliability and stability of equipment operation and reducing the risk of failure caused by displacement of connecting components. Strengthening the support structure ensures system stability and extends equipment life: The support mechanism, through the coordinated cooperation of the support ring, connecting plate, base plate, support plate, docking plate, and connecting ring, constructs a stable and balanced support system. Two support rings fixed to the outside of the conveying pipe provide a solid installation foundation for the entire support structure, enabling the even transfer of the force from the conveying pipe to the connecting plate. The rigid connection between the connecting plate and the base plate further disperses the force, enhancing the overall load-bearing capacity of the support structure. The support plate and the connecting ring outside the hydrocyclone separator, through the tight fit of the docking plate, achieve a reliable connection between the support mechanism and the hydrocyclone separator, ensuring a stable connection between the hydrocyclone separator and the support mechanism. This support structure design effectively resists the impact of high-velocity fluids and the external forces caused by equipment vibration, preventing bending, deformation, or breakage of components such as connecting discs and conveying pipes during operation. This further enhances the overall structural strength and stability of the system, effectively avoiding accelerated wear and loosening of connections caused by equipment shaking and displacement. Simultaneously, the stable support environment reduces vibration and impact during equipment operation, lowers fatigue wear on components, extends equipment lifespan, and reduces the frequency of equipment replacement and maintenance, thus reducing long-term operating costs for enterprises. Improved system adaptability and ensured production continuity: The overall structural design of this invention fully considers the complex working conditions of zinc smelting. The anti-locking design of the connecting mechanism and the stable design of the support mechanism complement each other, enabling the system to adapt to harsh working environments with high flow rates, strong corrosion, and high vibration, exhibiting strong adaptability to various operating conditions. The high stability and reliability of the system during operation effectively avoids frequent production line shutdowns due to equipment failure, ensuring the continuity of the production process and helping enterprises stabilize production capacity and improve production efficiency.In addition, the ease of equipment disassembly and assembly ensures that enterprises can respond quickly to production needs and handle equipment problems in a timely manner, thereby enhancing the flexibility and adaptability of enterprise production.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0023] Example: Figures 1-5 As shown, this embodiment proposes a buffer flow stabilization and cyclone separation system for thick underflow in zinc smelting, including a buffer flow stabilization chamber 1 to provide a stable fluid environment. A connecting mechanism 2 is provided on the outer side of the buffer flow stabilization chamber 1, a support mechanism 3 is provided on the outer side of the connecting mechanism 2, and a cyclone separator 4 is fixedly connected to the outer side of the connecting mechanism 2.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the connecting mechanism 2 includes a conveying pipe 21 fixedly connected to the outside of the buffer flow stabilizing chamber 1 to ensure stable fluid delivery. A connecting plate 22 is fixedly connected to the outside of the conveying pipe 21, providing fixation and support. A sliding column 23 is slidably connected inside the connecting plate 22, designed to provide sliding capability. A limit ring 24 is fixedly connected to one side of the sliding column 23, designed to provide limiting capability and prevent the sliding column 23 from falling off. A docking block 25 is slidably connected to the outside of the sliding column 23, designed to provide docking capability. A docking groove 26 is opened on the top of the docking block 25, designed to provide limiting capability. A locking component 27 is installed inside the docking block 25, and a limit component 28 is installed inside the docking groove 26.

[0025] like Figure 4 As shown, the locking assembly 27 includes a bolt 272 threadedly connected inside the connecting disc 22, designed to provide locking capability so that the connecting disc 22 is locked. A nut 271 is slidably connected inside the mating block 25, designed to provide locking space for the bolt 272. The external threads of the bolt 272 are connected inside the nut 271. When the nut 271 slides inside the mating block 25, it provides placement space for the nut 271, preventing the nut 271 from locking up and making it impossible to separate the connecting disc 22.

[0026] like Figure 4 and Figure 5 As shown, the limiting component 28 includes a support column 282 slidably connected inside the docking block 25, which is designed to provide support. A locking column 283 is slidably connected inside the docking block 25, which is designed to provide limiting capability. At the same time, the locking column 283 can penetrate through the interior of the docking block 25 and the interior of the sliding column 23 to prevent the docking block 25 from sliding during use. A connecting plate 281 is fixedly connected to the top of the locking column 283, which is designed to provide connection capability, so that the locking column 283 and the support column 282 can be removed together at the same time.

[0027] like Figure 4 As shown, the outer side of the limiting ring 24 is close to the conveying pipe 21, and the outer side of the docking block 25 is away from the limiting ring 24. The connection between the bolt 272 and the nut 271 allows the connecting plate 22 to be locked and fixed. At the same time, the docking block 25 provides limiting space for the bolt 272, which can prevent the nut 271 from slipping and locking when it is removed.

[0028] like Figure 1 and Figure 2 As shown, the support mechanism 3 includes two support rings 31 fixedly connected to the outside of the conveying pipe 21, which are designed to provide connection capability. The bottom of the two support rings 31 is fixedly connected to a connecting plate 32, which is designed to provide support capability.

[0029] like Figure 1 As shown, a base plate 33 is fixedly connected to the bottom of the connecting plate 32, which is designed to provide connection capability. A support plate 34 is fixedly connected to the outside of the conveying pipe 21, that is, the side closest to the connecting plate 32, which is designed to provide support capability.

[0030] like Figure 2 As shown, the top of the support plate 34 is fixedly connected to the docking plate 36, which is designed to provide connection capability. At the same time, the support plate 34 can provide stable support for the connecting ring 35. The external of the cyclone separator 4 is fixedly connected to the connecting ring 35, which is designed to provide stable support capability for the base plate 33.

[0031] like Figure 2 As shown, the outer sides of the base plate 33 are fixedly connected to the outer adjacent sides of the support plate 34 and the connecting ring 35, respectively, so that the base plate 33 can be stabilized by the support plate 34 and the connecting ring 35, preventing the connecting plate 22 from bending, and the outer side of the connecting ring 35 is located at the bottom of the connecting plate 22.

[0032] Working Principle: Buffering and Stabilizing Treatment: The high-concentration slurry discharged from the thickener first enters the buffer and stabilizing chamber 1. Through its special internal structural design, the buffer and stabilizing chamber 1 buffers and stabilizes the flow of the incoming slurry. Within the chamber, the slurry undergoes expansion and flow guidance, weakening turbulence and reducing velocity fluctuations. This results in a more uniform and stable velocity distribution, preventing sudden changes in slurry velocity from adversely affecting subsequent cyclone separation processes. This provides a stable fluid environment for subsequent cyclone separation operations, ensuring that the cyclone separator 4 can efficiently perform its separation function.

[0033] The material conveying and connecting mechanism 2 operates as follows: After buffering and stabilizing, the slurry is continuously and stably conveyed to the hydrocyclone 4 through the conveying pipe 21. The conveying pipe 21 serves as the core conveying channel, and its externally fixed connecting plate 22 provides precise installation and sliding guidance for the sliding column 23. The sliding column 23 can slide flexibly along its axis inside the connecting plate 22. A limiting ring 24 at one end effectively restricts the sliding stroke of the sliding column 23, preventing it from detaching from the connecting plate 22 and ensuring the integrity and safety of the connecting mechanism 2. The other end of the sliding column 23 is connected to the docking block 25. The docking groove 26 on the top of the docking block 25 precisely docks with the corresponding connecting component of the hydrocyclone 4, achieving the initial positioning of the conveying pipe 21 and the hydrocyclone 4. The locking assembly 27 inside the docking block 25 is connected to the nut 271 by bolts 272, locking the connecting plate 22 and the docking block 25 together, thus completing the stable connection between the conveying pipe 21 and the hydrocyclone separator 4. Simultaneously, the sliding space inside the docking block 25 provides room for the nut 271 to move, preventing it from locking up and ensuring convenient disassembly and assembly. The support column 282 in the limiting assembly 28 provides longitudinal support for the docking block 25, while the locking column 283 extends laterally through the docking block 25 and the sliding column 23, forming a bidirectional limiting mechanism to further restrict the displacement of the docking block 25 and prevent it from sliding during equipment operation. When maintenance or component replacement is required, the operator can first remove the connecting plate 281 from the limiting assembly 28, simultaneously pull out the locking column 283 and the support column 282, and then easily separate the bolt 272 from the nut 271 by rotating the bolt 272, completing the component disassembly.

[0034] Support and stabilizing function of support mechanism 3: Support mechanism 3 continuously provides support and stability during system operation. Two support rings 31 fixed to the outside of the conveying pipe 21 are tightly fitted to the outer wall of the conveying pipe 21 and are secured by welding or bolts 272 to ensure a firm connection. This allows the fluid impact force and its own weight, which are experienced by the conveying pipe 21 during operation, to be evenly transferred to the connecting plate 32 below. The connecting plate 32 is made of high-strength material and has good rigidity and load-bearing capacity, which can further transfer the load to the bottom plate 33. The bottom plate 33 is fixedly connected to the support plate 34 and the connecting ring 35 on both sides. The support plate 34 is fixed to the outside of the conveying pipe 21, providing a stable support point for the bottom plate 33. The connecting ring 35 is fixed to the outside of the hydrocyclone 4, forming a rigid connection with the bottom plate 33. This allows the force on the hydrocyclone 4 to be transferred to the bottom plate 33 and support mechanism 3 through the connecting ring 35, achieving force coordination between the conveying pipe 21 and the hydrocyclone 4. The entire support structure forms a closed-loop force transmission system, which can effectively disperse various loads generated during equipment operation, resist the external force caused by fluid impact and vibration, prevent bending and deformation of components such as connecting plate 22 and conveying pipe 21, avoid shaking or displacement of the entire equipment, and ensure that the system can operate stably and safely under long-term complex working conditions.

[0035] Cyclone Separation Operation: After being buffered and stabilized, the slurry enters the cyclone separator 4. The cyclone separator 4 utilizes centrifugal force to efficiently separate the solid and liquid components. The slurry enters tangentially inside the cyclone separator 4, forming a high-speed rotating vortex. Under the action of centrifugal force, the solid particles in the slurry, due to their higher density, are thrown towards the inner wall of the cyclone separator 4, moving downwards along the inner wall and eventually exiting from the bottom outlet. The liquid in the slurry, due to its lower density, concentrates at the center of the vortex, forming an upward internal vortex, and exits from the top overflow outlet. Through this separation process, the solid particles and liquid in the slurry are effectively separated. The separated solid particles and liquid are then transported to their respective subsequent processes, completing the zinc smelting thickened underflow treatment process and providing qualified materials for subsequent production processes.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
