Description

Technical Field

[0001] This utility model relates to the field of coal processing technology, and in particular to a low-noise coal crushing device. Background Technology

[0002] Coal processing refers to a series of treatments performed on mined raw coal to change its physical and chemical properties, making it more suitable for specific industrial uses or improving its product quality. This process includes multiple stages, such as coal washing, crushing, screening, molding, and upgrading. Coal crushing is a key and fundamental stage in coal processing. Its main purpose is to break coal from larger lumps into smaller particles to facilitate subsequent coal processing, transportation, and combustion.

[0003] Currently used coal crushing equipment can typically only achieve a single particle size crushing effect during operation, resulting in the crushed coal particles failing to meet the requirements of all process flows. In addition, this type of equipment generates significant noise during operation, leading to a significant noise pollution problem. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the particle size of coal crushing cannot be adjusted and the overall noise is relatively large. To this end, we propose a low-noise coal crushing device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a low-noise coal crushing device, including a crushing device shell, a feed inlet at the top of the crushing device shell, adjusting grooves at both the front and rear ends of the crushing device shell, two sliding blocks slidably connected inside the adjusting grooves, two crushing rollers installed inside the crushing device shell, an input block installed on the outer side of the sliding blocks, four fixing blocks fixedly connected to both sides of the crushing device shell, adjusting rods slidably connected inside the fixing blocks, several limiting grooves at the top and bottom of the adjusting rods, a handle fixedly connected to the side of the adjusting rod away from the sliding blocks, and the side of the adjusting rod near the sliding blocks fixedly connected to the sliding blocks, sliding grooves at the top and bottom of the fixing blocks, a sliding rod slidably connected inside the sliding grooves, a push-pull plate fixedly connected to the end of the sliding rod away from the fixing blocks, a spring slidably connected to the surface of the sliding rod, the end of the spring spring away from the push-pull plate fixedly connected to the fixing block, and the end of the spring spring near the push-pull plate fixedly connected to the push-pull plate.

[0006] Preferably, a limiting plate is fixedly connected inside the adjusting groove, and energy storage springs are fixedly connected to both sides of the limiting plate. The side of the energy storage spring closest to the sliding block is fixedly connected to the sliding block.

[0007] Preferably, two guide plates are installed inside the shell of the crushing device, and the front and rear ends of the guide plates are fixedly connected to the inside of the shell of the crushing device.

[0008] Preferably, the front and rear ends of the fixed block are provided with first sliding grooves, and the front and rear ends of the adjusting rod are fixedly connected with first sliders, and the interior of the first sliding groove is slidably connected to the first slider.

[0009] Preferably, a second sliding groove is provided on both sides of the sliding groove, and a second slider is fixedly connected to both sides of the sliding rod, with the interior of the second sliding groove slidably connected to the second slider.

[0010] Preferably, the crushing roller is made of high-strength aluminum alloy.

[0011] Preferably, the sliding groove is used in conjunction with the limiting groove, and the surface of the adjusting rod is provided with a self-lubricating coating.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, when the distance between the two crushing rollers needs to be adjusted, the push-pull plate is pulled outward, causing the sliding rod to be pulled out of the limiting groove, thus releasing the limiting position of the adjusting rod. The adjusting rod is then moved, causing it to move the sliding block to the appropriate position, thereby adjusting the gap between the crushing rollers. After adjustment, the stored elastic force of the spring is released, causing the sliding groove to re-insert into the limiting groove, thus fixing the adjusting rod and the crushing rollers synchronously. Coal is then fed into the feed inlet and connected to the output device via the input block. After the coal is crushed, the design of the guide plate reduces the impact force when the coal falls, thus achieving noise reduction during coal crushing. By adjusting the distance between the crushing rollers, the particle size of the crushed coal can be precisely controlled according to specific usage conditions, enabling the device to produce coal with uniform particle size that meets the requirements of the coking process, thus improving coke quality. Furthermore, this device reduces noise during coal crushing, preventing significant noise pollution. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: a low-noise coal crushing device, including a crushing device shell 1, a feed inlet 2 at the top of the crushing device shell 1, adjusting grooves 3 at both the front and rear ends of the crushing device shell 1, two sliding blocks 4 slidably connected inside the adjusting grooves 3, two crushing rollers 5 installed inside the crushing device shell 1, the inner side of the sliding blocks 4 rotatably connected to the crushing rollers 5, an input block 7 installed on the outer side of the sliding blocks 4, and four fixing blocks 8 fixedly connected to both sides of the crushing device shell 1, with adjusting rods 9 slidably connected inside the fixing blocks 8, and the top of the adjusting rods 9... The fixed block 8 has several limiting grooves 10 at both its top and bottom. A handle 11 is fixedly connected to the side of the adjusting rod 9 away from the sliding block 4, and the side of the adjusting rod 9 near the sliding block 4 is fixedly connected to the sliding block 4. Sliding grooves 12 are provided at both the top and bottom of the fixed block 8. A sliding rod 13 is slidably connected inside the sliding groove 12. A push-pull plate 14 is fixedly connected to the end of the sliding rod 13 away from the fixed block 8. A spring spring 15 is slidably connected to the surface of the sliding rod 13. The end of the spring spring 15 away from the push-pull plate 14 is fixedly connected to the fixed block 8, and the end of the spring spring 15 near the push-pull plate 14 is fixedly connected to the push-pull plate 14. Next, two guide plates 6 are installed inside the crushing device housing 1. The front and rear ends of the guide plates 6 are fixedly connected to the inside of the crushing device housing 1. When it is necessary to adjust the distance between the two crushing rollers 5, the push-pull plate 14 is pulled outward, causing the sliding rod 13 to be pulled out of the limiting groove 10, thus releasing the limiting of the adjusting rod 9. At this time, the adjusting rod 9 is moved, causing the adjusting rod 9 to drive the sliding block 4 to adjust to the appropriate position, thereby achieving the adjustment of the gap between the crushing rollers 5. After the adjustment is completed, the elastic force stored in the spring spring 15 is released, causing the sliding groove 12 to be inserted back into the limiting groove 10, so that the adjusting rod 9 and the sliding block 4 are adjusted to the appropriate position. The crushing rollers 5 are synchronously fixed. At this time, coal is put into the feed inlet 2 and connected to the output device through the input block 7. After the coal is crushed, the design of the guide plate 6 will make the coal have a smaller impact force when falling, thereby achieving the noise reduction effect during coal crushing. By adjusting the distance between the crushing rollers 5, the particle size of the crushed coal can be precisely controlled according to the specific usage conditions, so that the device can produce coal with uniform particle size that meets the requirements of the coking process, which helps to improve the quality of coke. Moreover, the device can achieve noise reduction during coal crushing and prevent the generation of large noise pollution.

[0023] Reference Figure 1 As shown in this embodiment: a limiting plate 16 is fixedly connected inside the adjusting groove 3. Energy storage springs 17 are fixedly connected to both sides of the limiting plate 16. The side of the energy storage spring 17 closest to the sliding block 4 is fixedly connected to the sliding block 4. By setting the energy storage spring 17, when the crushing roller 5 is used up, the adjusting rod 9 is released from the limit. At this time, the elastic force stored in the energy storage spring 17 drives the sliding block 4 to spring back to the initial position, thereby achieving the rapid reset of the crushing roller 5 after use, which is convenient for the next use by the staff.

[0024] Reference Figure 5 As shown in this embodiment: the front and rear ends of the fixed block 8 are provided with first sliding grooves 18, and the front and rear ends of the adjusting rod 9 are fixedly connected with first sliders 19. The interior of the first sliding groove 18 is slidably connected to the first slider 19. Through the setting of the first sliding groove 18 and the first slider 19, the adjusting rod 9 can provide a stable limiting effect when sliding inside the fixed block 8, so that the adjusting rod 9 is not easy to deviate when driving the crushing roller 5 to adjust its position, thereby effectively ensuring the adjustment accuracy and stability of the crushing roller 5.

[0025] Reference Figure 6 As shown in this embodiment: a second sliding groove 20 is provided on both sides inside the sliding groove 12, and a second slider 21 is fixedly connected to both sides of the sliding rod 13. The interior of the second sliding groove 20 is slidably connected to the second slider 21. Through the setting of the second sliding groove 20 and the second slider 21, the sliding rod 13 can form a stable limiting effect when moving inside the sliding groove 12, so that the sliding rod 13 will not move excessively, effectively improving the stability of the adjusting rod 9 when fixing and unfixing.

[0026] Reference Figure 3 As shown in this embodiment, the crushing roller 5 is made of high-strength aluminum alloy. By using aluminum alloy to make the crushing roller 5, the weight of the crushing roller 5 can be significantly reduced due to the low density and light weight of aluminum alloy, thereby achieving the lightweighting of the equipment and making it easier to adjust. In addition, the surface of aluminum alloy is relatively smooth, resulting in relatively less friction with coal during the crushing process and relatively lower noise.

[0027] Reference Figure 5 As shown in this embodiment: the sliding groove 12 is used in conjunction with the limiting groove 10, and the surface of the adjusting rod 9 is provided with a self-lubricating coating. By using the sliding groove 12 and the limiting groove 10 in conjunction, the crushing roller 5 is less likely to shake during the position fixing process, thereby effectively ensuring the stability of the crushing roller 5 when it is fixed. By providing a self-lubricating coating, the adjusting rod 9 can have less resistance during the movement process, which can make the adjustment efficiency of the crushing roller 5 higher and further improve the adjustment.

[0028] Working principle: When it is necessary to adjust the distance between the two crushing rollers 5, pull the push-pull plate 14 outward, causing the sliding rod 13 to be pulled out of the limiting groove 10, thus releasing the limiting position of the adjusting rod 9. Then, move the adjusting rod 9, causing it to drive the sliding block 4 to adjust to the appropriate position, thereby achieving the adjustment of the gap between the crushing rollers 5. After adjustment, the elastic force stored in the spring spring 15 is released, causing the sliding groove 12 to re-insert into the limiting groove 10, thus fixing the adjusting rod 9 synchronously with the crushing rollers 5. At this time, coal is fed into the feed inlet 2 and connected to the output device through the input block 7. After the coal is crushed, the design of the guide plate 6 will cause the coal to fall... The crushing rollers 5 have a smaller impact force, thus reducing noise during coal crushing. The adjustable distance between the crushing rollers 5 allows for precise control of the crushed coal particle size according to specific usage conditions, enabling the device to produce coal with uniform particle size that meets coking process requirements, thus improving coke quality. Furthermore, the device reduces noise during coal crushing, preventing significant noise pollution. With the energy storage spring 17, after the crushing rollers 5 have finished using, the adjusting rod 9 is released from its limit. The stored elasticity of the energy storage spring 17 then causes the sliding block 4 to spring back to its initial position, achieving rapid return of the crushing rollers 5 after use. The reset mechanism facilitates future use by the staff. The first slide groove 18 and the first slider 19 provide a stable limiting effect when the adjusting rod 9 slides inside the fixed block 8, preventing deviation when the adjusting rod 9 moves the crushing roller 5 to adjust its position. This effectively ensures the accuracy and stability of the crushing roller 5's adjustment. The second slide groove 20 and the second slider 21 provide a stable limiting effect when the sliding rod 13 moves inside the slide groove 12, preventing excessive movement of the sliding rod 13 and effectively improving the stability of the adjusting rod 9 when fixing and releasing it. The crushing roller 9 is made of aluminum alloy. Roller 5, due to the low density and light weight of aluminum alloy, significantly reduces the weight of the crushing roller 5, thereby achieving lightweighting of the equipment and making it easier to adjust. In addition, the surface of aluminum alloy is relatively smooth, resulting in less friction with coal during the crushing process and relatively lower noise. The combination of sliding groove 12 and limiting groove 10 prevents the crushing roller 5 from shaking during the fixed position, thus effectively ensuring the stability of the crushing roller 5 when fixed. The self-lubricating coating reduces the resistance of the adjusting rod 9 during movement, making the adjustment efficiency of the crushing roller 5 higher and further improving the adjustment.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
