Description

Technical Field

[0001] This utility model relates to the field of non-metallic mineral technology, and in particular to a mineral processing device for the selection of non-metallic mineral materials. Background Technology

[0002] Non-metallic minerals are those that do not have a metallic or submetallic luster, are colorless or have various light colors, are transparent or translucent under a thin slice of 0.03 mm, and have poor electrical and thermal conductivity.

[0003] A search revealed that utility model CN218901980U discloses a crushing and processing equipment for non-metallic mineral products, including a crushing chamber and two support platforms. The two support platforms are respectively installed on both sides of the crushing chamber. The crushing chamber is equipped with a crushing and processing structure, which includes: two first drive motors, a processing frame, two crushing rollers, a collection hopper, a collection component, and a secondary processing component. This utility model relates to the technical field of crushing and processing equipment. This invention adopts a multi-stage crushing process, allowing multiple crushing operations on non-metallic mineral products with a single feeding, ensuring the crushing effect of non-metallic mineral products. At the same time, the particle size of the crushed non-metallic mineral products can be adjusted by changing the screen specifications, eliminating the need for multiple feedings of non-metallic mineral products. This ensures the crushing effect of non-metallic mineral products while increasing the overall crushing efficiency and reducing the overall labor intensity of workers.

[0004] Although this type of crushing equipment can crush non-metallic mineral products, some of these products are too large to easily enter the crushing rollers during crushing. As a result, they remain inside the device and cannot be crushed properly. Workers then need to manually remove them, process them again, and put them back into the device. This process is cumbersome, reduces work efficiency, and is inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing crushing equipment, which, although capable of crushing non-metallic mineral products, often have drawbacks such as large size, making it difficult for some products to enter the crushing rollers during crushing, requiring removal and further processing, resulting in cumbersome operation and reduced work efficiency. Therefore, this invention proposes a mineral processing device for the selection of non-metallic mineral materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mineral processing device for the selection of non-metallic mineral materials includes a crushing box with openings at the top and bottom. Two symmetrically arranged second gears are rotatably connected between the inner walls of the two sides of the crushing box, with one end of each second gear rotatably penetrating the crushing box. A spur gear is fixedly sleeved on the outer wall of each second gear, and the two spur gears mesh with each other. A servo motor is fixedly connected to one side of the crushing box, and the output shaft of the servo motor rotatably penetrates the crushing box and is fixedly connected to one end of one of the second gears. Fixed triangular blocks are fixedly connected to the inner walls of both sides of the crushing box, with both fixed triangular blocks located on top of the crushing roller. The fixed triangular blocks are used to gather the material in the middle.

[0008] The same set of screening components is installed between the inner walls of both sides of the crushing box. The screening components are used to screen the material by size.

[0009] Two symmetrically arranged strip-shaped holes are opened on one side of the crushing box. A sliding block slides through the inside of the strip-shaped hole. A second spring is fixedly connected between one side of the sliding block and the inner wall of one side of the strip-shaped hole. An extrusion component for crushing and grinding the material is fixedly connected to one end of the sliding block near the inside of the crushing box.

[0010] A drive assembly for moving two sliding blocks is installed on one outer wall of the crushing chamber.

[0011] In one possible design, the screening assembly includes a sieve plate slidably connected between the inner walls of both sides of the crushing chamber. The sieve plate is slidably connected to the inner wall of the crushing chamber via a slider and a slide rail. A fixed strip plate is fixedly connected to one inner wall of the crushing chamber. The fixed strip plate is located on the side below the sieve plate. Two first springs are symmetrically arranged and fixedly connected between the top of the fixed strip plate and the bottom of the sieve plate. The sieve plate is inclined.

[0012] In one possible design, the extrusion assembly includes an extrusion block fixedly connected to one end of a sliding block, with multiple spherical protrusions fixedly connected to one side of the extrusion block, and both extrusion blocks are located above the sieve plate.

[0013] In one possible design, the drive assembly includes a third rotating shaft rotatably connected to one side of the crushing chamber. An incomplete gear is fixedly sleeved on the outer wall of the third rotating shaft. A connecting block is fixedly connected to one side of each of the two sliding blocks. The two connecting blocks are arranged in a centrally symmetrical manner. A rack is fixedly connected to one end of each connecting block. The two racks are located above and below the incomplete gear, respectively, and the racks mesh with the incomplete gear.

[0014] In one possible design, a first rotating shaft is rotatably connected to one side of the crushing chamber. One end of the first rotating shaft rotates through the crushing chamber and is fixedly connected to one end of one of the second gears. Synchronous pulleys are fixedly sleeved on the outer walls of both the first and third rotating shafts, and the same synchronous belt is driven sleeved on the outer walls of the two synchronous pulleys.

[0015] In one possible design, two symmetrically arranged triangular inclined plates are fixedly connected to the top of the sieve plate. One side of the triangular inclined plate abuts against the extrusion block, and the side of the triangular inclined plate away from the extrusion block is inclined.

[0016] In one possible design, a feed hopper is fixedly connected to the top of the crushing chamber, and the bottom of the feed hopper is connected to the top of the crushing chamber.

[0017] In this application, during use, the non-metallic minerals to be crushed are fed into the crushing box through the feed hopper. At this time, smaller non-metallic minerals can be directly moved to the bottom of the screen plate. The servo motor is started, and the output shaft of the servo motor drives the second gear to rotate. The second gear is driven to rotate through the external spur gear. The two second gears can drive the two crushing rollers to rotate. The crushing rollers crush the non-metallic minerals. The crushed material is discharged through the bottom of the crushing box. The setting of two fixed triangular blocks can move the material to the middle position of the crushing box, which is convenient for the subsequent crushing process.

[0018] Larger materials that cannot pass through the screen plate slide down the surface of the screen plate to one end. When the second gear rotates, it drives the first shaft to rotate. The first shaft drives the third shaft to rotate through the synchronous belt and synchronous pulley. The third shaft drives the incomplete gear to rotate. There are two sets of teeth on the top of the incomplete gear. The two sets of teeth mesh with two racks and drive the two racks to move closer together. The two racks drive the two connecting blocks and sliding blocks to move closer together. The sliding blocks drive the two squeezing blocks to move closer together and squeeze the second spring. At this time, the two squeezing blocks and the spherical protrusion squeeze and crush the larger non-metallic minerals. The crushed non-metallic minerals fall through the screen plate and undergo a further crushing process. When the racks and the incomplete gear no longer mesh, the fixed triangular block and the sliding block move away from each other under the elastic force of the second spring and reset. This allows for continuous squeezing and continuous operation. The triangular inclined plate can prevent materials from falling onto the back of the squeezing blocks and affecting their normal reset. At the same time, when the material falls, the screen plate squeezes the first spring, which causes continuous vibration and improves the screening efficiency.

[0019] Beneficial effects: High-efficiency screening and crushing: By setting up a screening component with sieve plates, non-metallic minerals can be initially screened when materials are fed in. Smaller minerals move directly through the sieve plates to the bottom, while larger minerals slide down the surface of the sieve plates, achieving preliminary separation of materials of different particle sizes. This provides a foundation for subsequent targeted processing and improves overall processing efficiency. Simultaneously, two crushing rollers crush the smaller minerals passing through the sieve plates, ensuring thorough crushing of materials of suitable particle sizes.

[0020] Targeted pretreatment and secondary crushing: For larger materials that cannot pass through the sieve, the extrusion components, including the incomplete gears and racks of the drive assembly, bring the extrusion blocks and spherical protrusions closer together to crush the larger minerals, allowing them to pass through the sieve and fall for further crushing. This pretreatment followed by secondary crushing ensures that all minerals are effectively crushed, improving the quality and uniformity of the crushing process, which is beneficial for subsequent mineral selection and processing.

[0021] Continuous and stable operation: The meshing relationship between the incomplete gear and the two sets of racks in the drive assembly allows the two extrusion blocks to move away from each other and reset under the elastic force of the second spring, thereby achieving continuous extrusion action, ensuring that the equipment can work continuously and stably, improving production efficiency, and reducing the time and energy waste caused by intermittent operation.

[0022] Optimized material conveying and resetting: The fixed triangular block design allows materials to move smoothly to the center of the crushing chamber, facilitating thorough crushing by the crushing rollers. This optimizes the material conveying path and crushing effect within the crushing chamber. The triangular inclined plate design effectively prevents materials from falling onto the back of the extrusion block, preventing interference with the normal resetting of the extrusion block and ensuring the accuracy and stability of the operation of all equipment components, thus guaranteeing the normal operation of the equipment.

[0023] Improve screening efficiency: When the material falls, the screen plate will squeeze the first spring and vibrate continuously. This vibration helps the material to disperse and fall quickly on the screen plate, reducing the accumulation and blockage of the material on the screen plate, significantly improving screening efficiency, and further accelerating the overall processing flow.

[0024] Compact structure and convenient operation: The equipment has a compact overall structure, and the components work together. Driven by a servo motor and combined with transmission components such as gears and synchronous belts, it realizes the linkage of functions such as crushing, screening and extrusion. It is simple and convenient to operate, and facilitates the installation, debugging and maintenance of the equipment, reducing the cost of use and the difficulty of operation.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Example 1

[0032] Reference Figure 1-4 A mineral processing device includes: a crushing box 1, the top and bottom of which are open; two symmetrically arranged second gears 8 are rotatably connected between the inner walls of the two sides of the crushing box 1, one end of each second gear 8 rotatably passes through the crushing box 1; a spur gear 7 is fixedly sleeved on the outer wall of the second gear 8, and the two spur gears 7 mesh with each other; a servo motor 6 is fixedly connected to one side of the crushing box 1, the output shaft of the servo motor 6 rotatably passes through the crushing box 1 and is fixedly connected to one end of one of the second gears 8; fixed triangular blocks 13 are fixedly connected to the inner walls of both sides of the crushing box 1, and the two fixed triangular blocks 13 are located on the top of the crushing roller 14. The fixed triangular blocks 13 are used to gather the material in the middle.

[0033] The same set of screening components is installed between the inner walls of both sides of the crushing box 1. The screening components are used to screen the size of the materials. The screening components include the same screen plate 12 that is slidably connected between the inner walls of both sides of the crushing box 1. The screen plate 12 is slidably connected to the inner wall of the crushing box 1 by a slider and a slide rail. A fixed strip plate 18 is fixedly connected to one side of the inner wall of the crushing box 1. The fixed strip plate 18 is located on the side below the screen plate 12. Two first springs 17 are symmetrically arranged and fixedly connected between the top of the fixed strip plate 18 and the bottom of the screen plate 12. The screen plate 12 is inclined.

[0034] Two symmetrically arranged strip-shaped holes 3 are opened on one side of the crushing chamber 1. A sliding block 22 slides through the inside of the strip-shaped hole 3. A second spring 23 is fixedly connected between one side of the sliding block 22 and the inner wall of one side of the strip-shaped hole 3. An extrusion assembly for crushing materials is fixedly connected to one end of the sliding block 22 near the inside of the crushing chamber 1. The extrusion assembly includes an extrusion block 15 fixedly connected to one end of the sliding block 22. Multiple spherical protrusions 16 are fixedly connected to one side of the extrusion block 15. Both extrusion blocks 15 are located above the screen plate 12. Larger materials that cannot pass through the screen plate 12 slide down the surface of the screen plate 12 to one end. When the second gear 8 rotates, it drives the first rotating shaft 5 to rotate. The first rotating shaft 5 drives the third rotating shaft 20 to rotate through the synchronous belt 4 and the synchronous pulley 21. The third rotating shaft 20 drives the incomplete gear 19 to rotate. There are two sets of mutually separated gear teeth on the top of the incomplete gear 19. The gear teeth mesh with the two racks 10 respectively, causing the two racks 10 to move closer to each other. The two racks 10 cause the two connecting blocks 9 and the sliding block 22 to move closer to each other. The sliding block 22 causes the two pressing blocks 15 to move closer to each other and press the second spring 23. At this time, the two pressing blocks 15 and the spherical protrusion 16 that are close to each other press and crush the larger non-metallic minerals. The crushed non-metallic minerals fall through the screen plate 12 and undergo a further crushing process. When the rack 10 and the incomplete gear 19 no longer mesh, the fixed triangular block 13 and the sliding block 22 move away from each other under the elastic force of the second spring 23 and reset, so that the pressing can continue and work continuously. The setting of the triangular inclined plate 11 can prevent the material from falling to the back of the pressing block 15 and affecting the normal reset of the pressing block 15. At the same time, when the material falls, the screen plate 12 will press the first spring 17, thus vibrating continuously and improving the screening efficiency.

[0035] A drive assembly for moving two sliding blocks 22 is installed on one outer wall of the crushing chamber 1. The drive assembly includes a third rotating shaft 20 rotatably connected to one side of the crushing chamber 1. An incomplete gear 19 is fixedly sleeved on the outer wall of the third rotating shaft 20. A connecting block 9 is fixedly connected to one side of each of the two sliding blocks 22. The two connecting blocks 9 are centrally symmetrically arranged. A rack 10 is fixedly connected to one end of each connecting block 9. The two racks 10 are located above and below the incomplete gear 19, respectively, and mesh with the incomplete gear 19. A first rotating shaft 5 is rotatably connected to one side of the crushing chamber 1. One end of the first rotating shaft 5 rotatably passes through the crushing chamber 1 and is fixedly connected to one end of one of the second gears 8. The outer walls of the first rotating shaft 5 and the third rotating shaft 20 are both... A synchronous wheel 21 is fixedly mounted, and the outer walls of the two synchronous wheels 21 are fitted with the same synchronous belt 4. The non-metallic minerals to be crushed are fed into the crushing box 1 through the feed hopper 2. At this time, the smaller non-metallic minerals that can pass through the screen plate 12 can be moved directly to the bottom of the screen plate 12. The servo motor 6 is started, and the output shaft of the servo motor 6 drives the second gear 8 to rotate. It also drives another second gear 8 to rotate through the external spur gear 7. The two second gears 8 can drive the two crushing rollers 14 to rotate. The crushing rollers 14 crush the non-metallic minerals. The crushed material is discharged through the bottom of the crushing box 1. The setting of the two fixed triangular blocks 13 can move the material to the middle position of the crushing box 1, which is convenient for the subsequent crushing process.

[0036] This application can be used in the field of non-metallic minerals, or in other fields applicable to this application.
