Description

Technical Field

[0001] This utility model relates to the technical field of metal new material crushing equipment, specifically a fine crushing production line for manganese powder production. Background Technology

[0002] Manganese powder is an important industrial raw material. In steel production, it serves as a deoxidizer and alloying agent, improving the strength, toughness, and wear resistance of steel. In the battery industry, manganese powder is a key raw material for producing zinc-manganese batteries, enhancing battery performance and lifespan. In the chemical industry, it can be used to produce various manganese compounds, such as manganese dioxide and manganese sulfate. The main raw material for manganese powder production is manganese ore, which has high hardness and often contains various impurities and associated minerals. To obtain manganese powder that meets the requirements of different applications, the manganese ore needs to undergo a series of processing steps, including crushing and grinding, with coarse crushing and fine crushing being the key processes.

[0003] The coarse crushing process is used to uniformly feed large pieces of manganese ore from the silo into the coarse crushing equipment via a feeding device. The coarse crushing equipment crushes the ore to a certain particle size, and then the coarsely crushed ore is transported to the fine crushing process via a conveying device. The fine crushing process is to further crush the raw material to a finer particle size to meet the requirements of subsequent grinding and other processes. The main equipment in the fine crushing process is a crusher, such as the existing technology "A double roll crusher for refining low-grade manganese ore into electrolytic manganese" (publication number: CN217856345U).

[0004] However, the existing technology still has the following technical problems:

[0005] 1. In existing crushers, the main shaft and auxiliary shaft are driven by gears. When the crusher is working, since the main shaft and auxiliary shaft cannot be separated, when large particles of material enter the crusher, the crushing load will increase instantly. The gears will bear huge impact loads, which may lead to accelerated wear of the gear teeth, cracks, or even shaft breakage, making the equipment unable to operate normally, resulting in poor equipment stability and reduced lifespan.

[0006] 2. Existing material storage bins generate significant dust during material feeding. Fine particles in the dust can enter the gaps and moving parts of the equipment, such as the seals of the storage bin and the transmission device of the feeding equipment. This increases friction between components, accelerates equipment wear, reduces the service life of the equipment, and also causes environmental pollution and affects the health of workers. Utility Model Content

[0007] This utility model provides a fine crushing production line for manganese powder production, which can solve the problem of poor buffering effect of existing crushers, which easily leads to poor equipment stability and shortened lifespan when large particles of material enter the crusher.

[0008] This application provides the following technical solution: a fine crushing production line for manganese powder production, including a feeding section and a crushing mechanism located below the feeding section; the crushing mechanism includes a casing, a crushing unit located inside the casing, and a buffer mechanism fixed on both sides of the casing, the buffer mechanism including strip blocks located on both sides of the casing, a slider slidably connected to the strip blocks, an adjusting rod threadedly connected to the strip blocks, and a compression spring located between the adjusting rod and the slider; the crushing unit includes a main shaft and a secondary shaft rotatably connected inside the casing, the two ends of the secondary shaft being rotatably connected to the slider.

[0009] Beneficial effects:

[0010] 1. Excellent buffering effect, ensuring equipment stability. When the crushing unit encounters significant resistance or impact, such as when crushing materials with high hardness or when foreign objects enter the crushing chamber, the sliders at both ends of the secondary shaft can slide on the strip block, compressing the compression spring, thereby absorbing and mitigating the impact force, reducing damage to the overall structure of the equipment, and extending the service life of the equipment. By rotating the adjusting rod, the preload of the compression spring can be adjusted, which allows for flexible changes in the buffering force of the buffer mechanism according to different crushing materials and production needs, enabling the equipment to better adapt to various working conditions and improving the adaptability and stability of the equipment.

[0011] 2. Protects the crushing unit and extends equipment life. The buffer mechanism effectively transmits the impact force to the compression spring for cushioning, preventing the impact force from acting directly on the main shaft and auxiliary shaft. This protects the main shaft, auxiliary shaft, and related transmission components of the crushing unit, reducing the possibility of wear, deformation, or damage to components caused by impact. This ensures the normal operation and crushing effect of the crushing unit and effectively extends the equipment life.

[0012] Furthermore, a pressure plate is fixed to the contact end between the adjusting rod and the compression spring, and a protrusion is provided at the end of the adjusting rod away from the pressure plate.

[0013] Beneficial effects: A pressure plate is fixed at the contact end between the adjusting rod and the compression spring, increasing the contact area between them. This allows for more even force distribution on the compression spring when adjusting its preload, preventing deformation or damage due to excessive localized stress, extending its lifespan, and ensuring the long-term stable damping and shock absorption function of the buffer mechanism. The protrusion facilitates the use of wrenches and other tools to adjust the axial displacement of the adjusting rod to adjust the spring's preload, enhancing convenience.

[0014] Furthermore, a main crushing roller is fixed on the main shaft, and a secondary crushing roller is provided on the secondary shaft. The main shaft and the secondary shaft are connected and driven by a belt pulley.

[0015] Beneficial effects: Belt pulley drives have good elasticity, which can buffer and absorb the impact generated during equipment operation when the main and auxiliary crushing rollers are working. During the fine crushing of manganese powder, the material crushing instant generates a large impact force, and the belt can act as a buffer, reducing damage to the main shaft, auxiliary shaft, and other equipment components, thus extending the service life of the equipment. When the equipment encounters overload conditions, such as when it encounters large pieces of extremely hard material, the belt will slip on the pulleys, preventing serious damage to the motor, main shaft, auxiliary shaft, etc., due to overload. This automatic slippage characteristic protects the entire transmission system and crushing unit, reducing the risk of equipment failure and improving the safety of equipment operation.

[0016] Furthermore, a receiving box is provided on the top of the chassis, and the receiving box is inverted conical in shape.

[0017] Beneficial effects: The inverted cone-shaped receiving box structure allows the manganese powder material falling from the feeding box to gradually converge to the center along the inner wall of the receiving box, and then accurately enter the crushing unit inside the machine, avoiding the material from scattering everywhere during the falling process, thus improving the accuracy and efficiency of the material entering the crushing chamber.

[0018] Furthermore, the feeding unit includes a feeding hopper and a feeding pipe fixed below the feeding hopper. The feeding pipe is inclined, with a baffle valve at the upper end and the lower end of the feeding pipe extending above the receiving box.

[0019] Beneficial effects: The slide gate valve at the upper end of the feed pipe allows for flexible control of the addition speed and amount of manganese powder. During production, the amount of material entering the machine can be precisely controlled by adjusting the opening of the slide gate valve based on factors such as the working load of the crushing unit and the characteristics of the manganese powder. This prevents overloading of the equipment due to excessive feeding or affecting production efficiency due to insufficient feeding, ensuring the stability and continuity of the production process. The inclined feed pipe utilizes gravity to allow the manganese powder to slide more smoothly from the feed hopper to the top of the receiving box, improving material conveying efficiency and ensuring a timely and stable supply of material to the crushing unit.

[0020] Furthermore, a ring-shaped dustproof net is fixed to the upper part of the inside of the hopper.

[0021] Beneficial effects: Since the filling storage tank is inverted on the hopper when adding materials, dust can easily leak out from the gap between the storage tank and the hopper. The dustproof net installed at the upper part of the hopper can prevent dust from escaping from the gap between the hopper edges, making it difficult for dust to spread to the surrounding environment and reducing dust pollution in the workshop. Attached Figure Description

[0022] Figure 1 This is the main structural view of the present invention.

[0023] Figure 2 for Figure 1 Left view of the crushing mechanism. Detailed Implementation

[0024] The following detailed description illustrates the specific implementation method:

[0025] The markings in the accompanying drawings of the instruction manual include: dustproof net 1, hopper 2, fixing block 3, partition 4, discharge pipe 5, dust suction pipe 6, outer cover 7, receiving box 8, machine box 9, strip block 10, support block 11, main crushing roller 12, main shaft 13, mounting block 14, secondary shaft 15, slider 16, adjusting rod 17, protrusion 171, fixing plate 18, pulley cover 19, pressure plate 20, compression spring 21, secondary crushing roller 22, and reduction motor 23.

[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, the fine crushing production line for manganese powder production includes a feeding section and a crushing mechanism located below the feeding section.

[0028] like Figure 1 As shown, the feeding unit includes a hopper 2 and a discharge pipe 5 fixed below the hopper 2. In practical applications, the hopper 2 is installed on a partition 4 on the second floor of the factory. Fixing blocks 3 are welded around the hopper 2 to fix the hopper 2 to the partition 4. The discharge pipe 5 is inclined and has a baffle valve at its upper end. A dust suction pipe 6 is installed on the outer side wall of the hopper 2 to absorb dust during feeding. A ring-shaped dustproof net 1 is also fixed to the upper part of the hopper 2. Since a filled storage tank is inverted on the hopper 2 during feeding, dust can easily leak out from the gap between the storage tank and the edge of the hopper 2. The ring-shaped dustproof net 1 at the upper part of the hopper 2 can prevent dust from escaping from the gap between the edge of the hopper 2, making it difficult for dust to spread to the surrounding environment and reducing dust pollution in the workshop.

[0029] like Figure 1 and Figure 2 As shown, the crushing mechanism includes a housing 9, a receiving box 8 connected above the housing 9, a crushing unit located inside the housing 9, and a buffer mechanism fixed on both sides of the housing 9; the receiving box 8 is inverted cone shape, and the lower end of the discharge pipe 5 extends to the top of the receiving box 8.

[0030] The buffer mechanism includes strip blocks 10 located on both sides of the housing 9, sliders 16 slidably connected to the strip blocks 10, adjusting rods 17 threadedly connected to the strip blocks 10, and a compression spring 21 located between the adjusting rods 17 and the sliders 16. A support block 11 is provided below the strip blocks 10 for support. A strip hole is opened in the middle of the strip blocks 10. A groove is provided in the strip blocks 10 so that the sliders 16 are slidably connected in the strip hole. A fixing plate 18 is provided in the strip hole of the strip blocks 10. The rod part of the adjusting rod 17 is rotatably connected to the fixing plate 18. A pressure plate 20 is also fixed at the contact end of the adjusting rod 17 and the compression spring 21. A protrusion 171 is provided on the end of the adjusting rod 17 that extends outside the strip blocks 10. The protrusion 171 makes it convenient for the operator to use a wrench or other tools to adjust the axial displacement of the adjusting rod 17 in order to adjust the preload of the compression spring 21, thereby improving convenience.

[0031] The crushing unit includes a main shaft 13 and a secondary shaft 15 rotatably connected within a housing 9. One end of the main shaft 13 is fixedly connected to the drive shaft of a reduction motor 23. A main crushing roller 12 is fixedly mounted on the shaft of the main shaft 13 within the housing 9. Mounting blocks 14 are rotatably connected to both ends of the main shaft 13, and the mounting blocks 14 are fixedly connected to the slotted holes of the strip-shaped block 10. A secondary crushing roller 22 is provided on the shaft of the secondary shaft 15 within the housing 9. The ends of the main shaft 13 and the secondary shaft 15 furthest from the reduction motor 23 are connected via... Figure 2 The transmission is connected by a pulley, and the pulley is protected by a pulley cover 19. The two ends of the secondary shaft 15 are rotatably connected to the slider 16. A discharge port is provided at the bottom of the casing 9. The material is crushed between the main crushing roller 12 and the secondary crushing roller 22 and discharged from the discharge port. An outer cover 7 is also provided on the outside of the casing 9, and a dust suction pipe 6 is provided on the top of the outer cover 7 to absorb dust.

[0032] The operation process of this production line is as follows:

[0033] The storage tank is inverted and placed on top of the hopper 2, so that the storage tank is positioned above the hopper 2. A dustproof net 1 is installed at the upper part of the inside of the hopper 2 to prevent dust from escaping from the gaps around the edge of the hopper 2. This prevents the dust from spreading to the surrounding environment and reduces dust pollution in the workshop. Then, the material can enter the receiving box 8 through the discharge pipe 5. The slide valve installed on the discharge pipe 5 can adjust the opening of the discharge pipe 5 to control the amount and speed of material discharge. Material entering the machine housing 9 from the receiving box 8 will be crushed between the main crushing roller 12 and the auxiliary crushing roller 22. The crushed material will be discharged from the discharge port at the bottom of the machine housing 9 and bagged. When encountering large particles, high-hardness materials, or foreign objects entering the crushing chamber, the sliders 16 at both ends of the auxiliary shaft 15 can slide on the strip block 10, so that the auxiliary crushing roller 22 is away from the main crushing roller 12. The two ends of the auxiliary shaft 15 compress the compression spring 21 through the slider 16, thereby absorbing and mitigating the impact force, reducing damage to the overall structure of the equipment, and extending the service life of the equipment. By rotating the adjusting rod 17, the preload of the compression spring 21 can be adjusted, which is beneficial to flexibly change the buffering force of the buffer mechanism according to different crushed materials and production needs, so that the equipment can better adapt to various working conditions and improve the adaptability and stability of the equipment.
