Description

Technical Field

[0001] This utility model belongs to the field of hydrocyclone technology, specifically a hydrocyclone for particle size classification of electrolytic manganese slag. Background Technology

[0002] Electrolytic manganese slag refers to the residue formed by impurities and solid substances in the electrolytic cell during the electrolysis of manganese. Electrolytic manganese is primarily a process of extracting manganese metal by electrolyzing manganese oxide ore (such as manganese ore). During this process, the electrolysis reaction produces manganese metal, oxygen, and some byproducts. The formation of electrolytic manganese slag is an unavoidable byproduct of manganese electrolysis, containing some unreduced impurities. The treatment of electrolytic manganese slag is a crucial issue that must be addressed in manganese production.

[0003] In existing technologies, hydrocyclones are frequently used to process electrolytic manganese slag. While these existing hydrocyclones are generally suitable for separating coarser particles, they fall short in terms of classification accuracy and separation efficiency for materials like manganese slag, which have a wide particle size range and significant differences in specific gravity. Multiple cycles are often required to achieve the desired classification effect, increasing processing costs.

[0004] Patent CN217781246U discloses a system for recovering valuable elements from electrolytic manganese leaching residue, including a ball mill and a hydrocyclone. The hydrocyclone used in this solution is a traditional hydrocyclone, which requires multiple separations to ensure effectiveness when processing manganese slag, thus increasing processing costs. Utility Model Content

[0005] The purpose of this invention is to provide a hydrocyclone for particle size classification of electrolytic manganese slag, in order to solve the following technical problems mentioned in the background art:

[0006] Traditional hydrocyclones have insufficient classification accuracy and separation efficiency. Multiple cycles are often required to achieve the desired classification effect.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A hydrocyclone for particle size classification of electrolytic manganese slag includes a cylindrical body and a conical cylinder connected together. The cylindrical body has a feed inlet and an overflow assembly, and the conical cylinder has a discharge outlet on one side of its bottom. The feed inlet is connected to one side of the top of the cylindrical body and located tangentially to the cylindrical body, communicating with the inner cavity of the cylindrical body. The overflow assembly includes an overflow pipe, a connecting top plate, a connecting bottom plate, a first connecting screw, a second connecting screw, a first fixing nut, and a second fixing nut. The overflow pipe is connected to the top of the cylindrical body and movably passes through it. An overflow inlet and an overflow outlet are respectively provided at both ends of the overflow pipe. The connecting top plate is fixed to the overflow pipe, and the connecting bottom plate is fixed to the cylindrical body. The first connecting screw movably passes through the connecting top plate and the connecting bottom plate, and the first fixing nut is threadedly connected to the first connecting screw and located between the connecting top plate and the connecting bottom plate. The second connecting screw movably passes through the connecting top plate and the connecting bottom plate, and the second fixing nut is threadedly connected to the second connecting screw and located at the bottom of the connecting bottom plate.

[0009] Furthermore, the cylinder includes a top cover, an upper cylinder, and a lower cylinder. The top cover is bolted to the top of the upper cylinder, and the lower cylinder is bolted to the bottom of the upper cylinder. A connector is provided on the connecting chassis, and the connecting chassis is connected to the connector.

[0010] Furthermore, a flange is provided on the top cover, and the connector is connected to the top cover flange.

[0011] Furthermore, a first sealing ring is provided between the upper cylinder and the top cover, a second sealing ring is provided between the upper cylinder and the lower cylinder, and a third sealing ring is provided between the lower cylinder and the cone.

[0012] Furthermore, a connecting nozzle is detachably connected to the bottom of the cone at the discharge port.

[0013] Furthermore, at least two sets of each of the first connecting screw, the second connecting screw, the first fixing nut, and the second fixing nut are provided.

[0014] Furthermore, the overflow outlet is located on the side wall of the overflow pipe.

[0015] Furthermore, an auxiliary discharge component is provided inside the overflow pipe to assist the overflow port in discharging material.

[0016] Furthermore, the auxiliary discharge component includes a screw conveyor blade, a rotating shaft, and a drive device; the rotating shaft is rotatably connected inside the overflow pipe, the screw conveyor blade is connected to the rotating shaft, and the drive device is connected to the rotating shaft, which is used to drive the rotating shaft to rotate.

[0017] Furthermore, the drive unit uses an electric motor.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In this invention, the hydrocyclone, through its cylindrical and conical design, effectively separates particles of different sizes using centrifugal force. When the slurry enters the cylinder through the inlet, it forms a high-speed rotating flow, causing larger particles to be subjected to greater centrifugal force and move towards the bottom of the conical section, while smaller particles are forced to rise with the internal swirling flow and are eventually discharged through the overflow pipe. This layout ensures efficient separation of particles of different sizes, providing excellent raw materials for subsequent processing. The overflow assembly is designed with adjustment capabilities, particularly the fit between the first connecting screw and the first fixing nut, allowing for precise adjustment of the overflow inlet position according to actual needs. This flexibility enables the hydrocyclone to optimize the separation effect based on different slurry compositions and particle size ranges. Furthermore, the adjustment of the overflow inlet position effectively addresses changes in the composition of the input material, adapting to the particle size diversity of electrolytic manganese slag.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Example:

[0027] A hydrocyclone for particle size classification of electrolytic manganese slag, such as Figure 1As shown, it includes a cylindrical body and a conical cylinder 7, which are connected. The cylindrical body is equipped with an inlet 1 and an overflow assembly 2. The conical cylinder 7 has an outlet 8 on one side of its bottom. The inlet 1 is connected to one side of the top of the cylindrical body and is located tangentially to the cylindrical body. The inlet 1 communicates with the inner cavity of the cylindrical body. Figure 2 as well as Figure 3 As shown, the overflow assembly 2 includes an overflow pipe 14, a connecting top plate 13, a connecting bottom plate 10, a first connecting screw 11, a second connecting screw 16, a first fixing nut 12, and a second fixing nut 17. The overflow pipe 14 is connected to the top of the cylinder and movably passes through the cylinder. An overflow inlet 18 and an overflow outlet 15 are respectively provided at both ends of the overflow pipe 14. The connecting top plate 13 is fixed to the overflow pipe 14, and the connecting bottom plate 10 is fixed to the cylinder. The first connecting screw 11 is movably passed through the connecting top plate 13 and the connecting bottom plate 10. The first fixing nut 12 is threadedly connected to the first connecting screw 11 and is located between the connecting top plate 13 and the connecting bottom plate 10. The second connecting screw 16 is movably passed through the connecting top plate 13 and the connecting bottom plate 10. The second fixing nut 17 is threadedly connected to the second connecting screw 16 and is located at the bottom of the connecting bottom plate 10.

[0028] The hydrocyclone consists of a cylindrical body and a conical tube 7, with the inner cavities of the two sections connected. During operation, the feed inlet 1 introduces the slurry into the hydrocyclone, where fluid pressure forces the material into a high-speed rotating flow. The cylindrical body primarily serves for initial separation and stabilizing the fluid flow, ensuring uniform material entry into the conical section for further classification. The conical tube 7 utilizes centrifugal force to classify particles; larger particles experience greater centrifugal force and move towards the bottom of the conical section. Fine particles within the hydrocyclone move upwards with the internal swirling flow and are discharged through the overflow assembly 2 for subsequent fine processing or recycling. Larger particles settle to the bottom and are discharged from the discharge outlet 8 for centralized collection and further processing. It should be noted that the internal flow of the hydrocyclone is divided into external and internal swirling flows. The external swirling flow primarily propels larger particles towards the bottom outlet, while the internal swirling flow carries finer particles towards the overflow outlet. The working principle of the hydrocyclone is a well-established technology and will not be elaborated upon here. In the overflow assembly 2, the first connecting screw 11 and the first fixing nut 12 are used to adjust the position of the overflow inlet 18 on the overflow pipe 14. Specifically, since the first fixing nut 12 is located between the connecting base plate 10 and the connecting top plate 13, rotating the first fixing nut 12 causes it to move axially in the direction of the first screw. When the connecting top plate 13 moves downward, it is restricted by the first fixing nut 12. Therefore, adjusting the position of the first fixing nut 12 can adjust the position of the connecting top plate 13. The connecting top plate 13 is fixedly connected to the overflow pipe 14, and adjusting the position of the connecting top plate 13 can adjust the position of the overflow inlet 18 on the overflow pipe 14. After determining the position of the overflow inlet 18, the connecting top plate 13 and the connecting base plate 10 are locked together by the second connecting screw 16 and the second fixing nut 17. The position of the connecting top plate 13 is fixed, which means the position of the overflow pipe 14 is fixed, and the overflow inlet 18 on the overflow pipe 14 is also fixed. Adjusting the position of the overflow inlet 18 can adjust the separation effect. When the overflow inlet 18 is adjusted upwards, larger and larger particles have difficulty entering it. In other words, the higher the overflow inlet 18 is, the smaller the size of the separated microparticles. However, in actual use, smaller particle sizes are not always better; the optimal size depends on the actual slurry composition. The adjustable overflow inlet enhances the equipment's adaptability, making it suitable for separating electrolytic manganese slag of different particle sizes, accommodating the diversity of particle sizes in electrolytic manganese slag, and ensuring efficient separation of large and fine particles. This ensures effective particle size classification during the separation process.

[0029] In a preferred embodiment, such as Figure 1As shown, the cylinder includes a top cover 4, an upper cylinder 5, and a lower cylinder 6. The top cover 4 is bolted to the top of the upper cylinder 5, and the lower cylinder 6 is bolted to the bottom of the upper cylinder 5. A connector 3 is provided on the connecting base 10, and the connecting base 10 is connected to the connector 3. The split design allows for quick disassembly and reassembly of each part when the equipment malfunctions or needs cleaning, reducing maintenance time and improving the maintainability of the equipment. The connector 3 is designed to facilitate connection with the connecting base 10 and ensure the connection stability of the connecting base 10.

[0030] In a preferred embodiment, such as Figure 3 As shown, a flange is provided on the top cover 4, and the connector 3 is connected to the flange of the top cover 4. The flange connection provides a larger contact surface and a more uniform pressure distribution, making the connection between the top cover 4 and the connector 3 more secure. The flange design makes the installation and removal of the connector 3 easier. With bolt fixing, operators can quickly replace or maintain the connector 3.

[0031] In a preferred embodiment, such as Figure 3 As shown, a first sealing ring 19 is provided between the upper cylinder 5 and the top cover 4, a second sealing ring 20 is provided between the upper cylinder 5 and the lower cylinder 6, and a third sealing ring 21 is provided between the lower cylinder 6 and the cone 7. The first sealing ring 19 prevents leakage of slurry or other fluids at the connection between the cylinder and the top cover 4, ensuring effective fluid flow within the equipment, preventing pollution to the external environment, and reducing material loss. The second sealing ring 20 provides a sealing effect between the upper cylinder 5 and the lower cylinder 6, helping to maintain the internal pressure required during operation. The third sealing ring 21 is located between the lower cylinder 6 and the cone 7, ensuring that the centrifugal force borne by the cone 7 during use does not cause fluid or particles to overflow from the connection, thereby maintaining the overall structural stability of the equipment. The first sealing ring 19, the second sealing ring 20, and the third sealing ring 21 are made of rubber or polytetrafluoroethylene.

[0032] In a preferred embodiment, such as Figure 1 As shown, a connecting nozzle 9 is detachably connected to the bottom of the cone 7 at the discharge port 8. The design of the connecting nozzle 9 allows for easy connection to different types of conveying equipment or storage containers as material passes through the discharge port 8, facilitating the collection and transfer of separated particles and improving work efficiency. The connecting nozzle 9 can be quickly disassembled or replaced as needed. This allows for flexible adjustment of the shape or size of the connecting nozzle 9 according to material properties, particle size, and other requirements under different operating conditions to adapt to different material handling needs. The detachable connection design also allows for easy removal of the connecting nozzle 9 for cleaning and maintenance of the equipment, facilitating internal cleaning.

[0033] In a preferred embodiment, such as Figure 2As shown, at least two sets of each of the first connecting screw 11, the second connecting screw 16, the first fixing nut 12, and the second fixing nut 17 are provided. The multiple sets of screws and nuts make the connection between the connecting top plate 13 and the connecting bottom plate 10 more secure. The even distribution of multiple screws effectively disperses the pressure applied to each connection point, reducing loosening caused by fatigue damage, thereby enhancing the stability of the overall structure. By providing at least two sets of the first connecting screw 11, the second connecting screw 16, the first fixing nut 12, and the second fixing nut 17 in the hydrocyclone, the connection strength, adjustment flexibility, and overall reliability of the equipment can be improved, thereby ensuring the efficient operation of the hydrocyclone.

[0034] In a preferred embodiment, such as Figure 1 As shown, the overflow outlet 15 is located on the side wall of the overflow pipe 14. Compared to the top outlet, the side wall overflow outlet 15 reduces the risk of blockage caused by solid particles. Fine particles are more easily discharged through the side wall outlet during their ascent. The overflow outlet 15 on the side wall allows for easy connection to other equipment or systems, enabling rapid material transfer and handling.

[0035] In a preferred embodiment, such as Figure 4 As shown, an auxiliary discharge component is installed inside the overflow pipe 14 to assist in the discharge from the overflow port. Further optimization includes a spiral conveyor blade 24, a rotating shaft 23, and a drive device 22. The rotating shaft 23 is rotatably connected inside the overflow pipe 14, the spiral conveyor blade 24 is connected to the rotating shaft 23, and the drive device 22 is connected to the rotating shaft 23 to drive the rotating shaft 23 to rotate. Further optimization uses a motor for the drive device 22. The auxiliary discharge component improves the discharge efficiency of the overflow port. The spiral conveyor blade 24 effectively guides and pushes fluid and solid particles towards the overflow port, thereby accelerating the discharge speed, ensuring rapid material discharge, and improving overall work efficiency. The auxiliary discharge component ensures that fine particles are discharged from the overflow port in a timely manner, avoiding mixing with large particles and improving product purity and quality. The spiral conveyor blade 24 reduces the deposition of solid particles through mechanical movement, effectively preventing blockage of the overflow pipe 14 caused by particle accumulation, thereby improving the operational reliability and stability of the equipment. The motor, as the drive unit 22, can adjust its speed according to actual needs.
