Description

Technical Field

[0001] This invention relates to the technical field of pulverizing equipment, and in particular to an ultrafine pulverizing device for non-metallic minerals. Background Technology

[0002] Ultrafine grinding technology is one of the key technologies in the modern powder processing field, especially in the non-metallic mineral processing industry, where it plays a vital role. Non-metallic minerals generally include kaolin, talc, graphite, wollastonite, zircon, barite, etc. Due to their unique physicochemical properties, they have wide applications in many industrial fields, such as ceramics, plastics, coatings, papermaking, pharmaceuticals, and cosmetics.

[0003] Existing ultrafine grinding methods for non-metallic minerals generally include blade grinding, hammer grinding, and roller grinding. These grinding methods mainly use high-speed impact or extrusion of raw materials to complete the grinding work. The degree of grinding of raw materials cannot be accurately controlled, and the randomness is relatively large. Moreover, the grinding work of raw materials needs to be carried out for a long time and repeatedly to break the raw materials into powder, resulting in low work efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a non-metallic mineral ultrafine pulverizing device, the specific technical solution of which is as follows:

[0005] A non-metallic mineral ultrafine pulverizing device includes a pulverizing box and a discharge structure. The pulverizing box and the discharge structure are connected. The axis of the pulverizing box is horizontal. A roller for pulverizing raw materials is rotatably installed inside the pulverizing box. The discharge structure is used to discharge the pulverized raw materials.

[0006] The crushing box consists of a feed inlet for feeding materials, a pressing zone for pressing raw materials, a first arc-shaped zone for primary pressing of raw materials, and a second arc-shaped zone for secondary pressing of raw materials. The roller is coaxial with the crushing box, the feed inlet faces upward, the distance between the pressing zone and the outer wall of the roller gradually decreases as the height decreases, the distance between the first arc-shaped zone and the outer wall of the roller gradually decreases along the rotation direction of the roller, and the distance between the second arc-shaped zone and the outer wall of the roller remains constant.

[0007] Furthermore, the roller is hollow inside, and a support shaft is coaxially arranged inside the roller. Multiple rotating rings are rotatably arranged on the support shaft. Multiple first springs are arranged on the outer wall of each rotating ring. Multiple push plates are slidably inserted on the outer circumference of the roller. The sliding direction of the push plates is along the radial direction of the roller. One end of the push plate extends outside the roller, and the other end of the push plate extends inside the roller and is connected to the first spring.

[0008] The end of the support shaft passes through the roller and the crushing box and extends beyond the crushing box. The roller rotates on the support shaft. The first spring provides elastic thrust to the push plate. When the push plate follows the roller to the position of the extrusion zone, the push plate extends and provides downward pressure to the raw material in the extrusion zone.

[0009] Furthermore, multiple teeth are provided on the roller between two adjacent push plates. The teeth are connected to the inside of the roller. The multiple teeth are parallel to each other. A filling plate is slidably provided in each tooth. A base plate is connected to the multiple filling plates. The base plate is located inside the roller.

[0010] When the toothed opening is located in the extrusion zone or the first arc zone, the filler plate is located inside the toothed opening. At this time, the edge of the toothed opening on the outer wall of the roller crushes the raw material. When the toothed opening is located in the second arc zone, the end face of the filler plate is coplanar with the outer wall of the roller, and the outer wall of the roller forms a complete arc surface.

[0011] Furthermore, a fixing ring is fitted and fixed on the outer wall of the support shaft. Annular grooves are provided on both the front and rear sides of the fixing ring. The annular grooves are composed of a first arc-shaped groove and a second arc-shaped groove. Multiple sliding columns are slidably arranged within the annular grooves. The sliding columns are connected to the base plate via a filling plate. When the sliding column slides in the first arc-shaped groove, the filling plate seals the tooth opening, and the outer wall of the roller forms a complete arc surface. When the sliding column slides in the second arc-shaped groove, the filling plate slides into the tooth opening.

[0012] Furthermore, a circular opening is provided on the side wall of the crushing box;

[0013] The discharge structure includes a discharge cylinder connected to a circular opening, a support plate inside the discharge cylinder, a rotating shaft rotatably mounted on the support plate, the rotating shaft being connected to a roller drive, and multiple fan blades mounted on the outer wall of the rotating shaft.

[0014] Furthermore, the discharge cylinder is in sliding contact with the crushing box, and the roller is connected to the rotating shaft through a transmission structure. The transmission structure includes multiple power rods arranged in a ring. The power rods are inclined along the axis of the rotating shaft, one end of the power rod is rotatably mounted on the rotating shaft, and the other end of the power rod is rotatably mounted on the roller.

[0015] Furthermore, the discharge cylinder is provided with a sliding opening, and a sliding column is slidably disposed inside the sliding opening. The sliding column is connected to the discharge cylinder by a second spring.

[0016] The sliding column is provided with an inclined surface. When the sliding column slides in the sliding opening, the area of ​​the sliding opening blocking the inclined surface of the sliding column changes, and outside air can enter the discharge cylinder through the gap between the sliding opening and the inclined surface.

[0017] Furthermore, a transmission sleeve is provided on the end face of the roller, the transmission sleeve is sleeved on the outer wall of the support shaft, and the transmission sleeve passes through the crushing box. The end of the support shaft is fixed to the outer wall of the crushing box by a fixing plate. The fixing plate is provided with a motor and a transmission wheel for providing power for the rotation of the transmission sleeve.

[0018] The advantages of this invention are:

[0019] By designing specific extrusion zones, a first arc zone, and a second arc zone, the crushing process of raw materials can be precisely controlled. The extrusion zone is used for rapid crushing of large pieces of raw material, the first arc zone for fine crushing, and the second arc zone for ultra-fine grinding. This staged crushing process can more effectively control the particle size distribution of the final product. Compared with traditional long-duration, repetitive crushing, this device greatly improves work efficiency through a continuous and efficient crushing process. The raw material undergoes a complete and continuous crushing cycle from feeding to final discharge, avoiding the problem of multiple processing steps required to achieve the desired particle size in traditional methods. Due to the optimized crushing process, the entire crushing process is more stable and continuous, which not only improves efficiency but also reduces energy consumption. Compared with traditional methods, this continuous crushing method can achieve better crushing results with lower energy input. In summary, the technical solution of this non-metallic mineral ultra-fine grinding device not only solves the problems existing in traditional crushing methods but also significantly improves crushing efficiency, product quality, and economic benefits, representing a major innovation in the field of modern powder processing.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0035] like Figures 1 to 3 As shown, the non-metallic mineral ultrafine pulverizing device of the present invention includes a pulverizing box 1 and a discharge structure 2. The pulverizing box 1 and the discharge structure 2 are connected. The axis of the pulverizing box 1 is horizontal. A roller 7 for pulverizing raw materials is rotatably provided inside the pulverizing box 1. The discharge structure 2 is used to discharge the pulverized raw materials.

[0036] The crushing box 1 consists of a feed inlet 3 for feeding materials, a pressing zone 4 for pressing raw materials, a first arc-shaped zone 5 for primary pressing of raw materials, and a second arc-shaped zone 6 for secondary pressing of raw materials. The roller 7 is coaxial with the crushing box 1. The feed inlet 3 faces upward. The distance between the pressing zone 4 and the outer wall of the roller 7 gradually decreases as the height decreases. The distance between the first arc-shaped zone 5 and the outer wall of the roller 7 gradually decreases along the rotation direction of the roller 7. The distance between the second arc-shaped zone 6 and the outer wall of the roller 7 is constant.

[0037] In detail, the distance between the inside of the crushing box 1 and the outer wall of the roller 7 decreases along the direction of the extrusion zone 4, the first arc zone 5, and the second arc zone 6. The crushing box 1 is cylindrical in shape. The feed inlet 3 is located on the upper left side of the crushing box 1 and is used to feed raw materials into the crushing box 1. The extrusion zone 4 is vertical. As the height decreases, the distance between the extrusion zone 4 and the outer wall of the roller 7 gradually decreases until it reaches a specified value. This area is mainly used to quickly crush larger raw materials into smaller particles. The distance between the first arc zone 5 and the outer wall of the roller 7 gradually decreases along the rotation direction of the roller 7. This area is used to grind and crush the small particles, so that the small particles eventually become powder. The second arc zone 6... The distance between the shaping zone 6 and the outer wall of the roller 7 is constant. This zone is mainly used for secondary grinding of powdered raw materials to further reduce their shape and achieve an ultra-fine state. That is, after the raw material enters from the feed inlet 3 and is initially crushed in the extrusion zone 4, it is crushed once in the first arc zone 5 and then crushed a second time in the second arc zone 6, thus completing the ultra-fine grinding work. During this process, the roller 7 continuously crushes the raw material over a long period of time. Its crushing cycle is long, and the crushing work is stable, continuous, and efficient. The crushed raw material can enter the discharge structure 2 through the gap between the inner wall of the crushing box 1 and the end face of the roller 7 and be discharged through the discharge structure 2.

[0038] It should be noted that the distance between the bottom of the extrusion zone 4 and the outer wall of the roller 7 is the maximum value of the distance between the first arc zone 5 and the roller 7, and the minimum value of the distance between the first arc zone 5 and the roller 7 is a constant value between the second arc zone 6 and the roller 7. This causes the distance between the inner wall of the crushing box 1 and the outer wall of the roller 7 to gradually decrease along the rotation direction of the roller 7, while the range of variation of the distance between the extrusion zone 4 and the outer wall of the roller 7 is the largest, which enables the rapid crushing of larger volumes of raw materials. The range of variation of the distance between the first arc zone 5 and the outer wall of the roller 7 is smaller, which enables the crushing of small particles of raw materials. The distance between the second arc zone 6 and the roller 7 not only limits the particle size of powdered raw materials, but also, due to the aggregation of raw materials between the second arc zone 6 and the roller 7, the roller 7 provides extrusion force between the raw materials, thereby crushing them together and achieving ultra-micro processing.

[0039] In actual use, the gap between the end face of the roller 7 and the inner wall of the crushing box 1 can be used for screening. Ultrafine raw materials can enter the discharge structure 2 through the gap, while larger particles will remain between the roller 7 and the crushing box 1. Due to the continuous rotation of the roller 7, when the roller 7 carries the raw material away from the second arc-shaped area 6, the raw material will re-enter the extrusion area 4 and continue to be periodically crushed in the crushing box 1.

[0040] By designing specific extrusion zone 4, first arc zone 5, and second arc zone 6, the crushing process of raw materials can be precisely controlled. Extrusion zone 4 is used for rapid crushing of large raw materials, first arc zone 5 for fine crushing, and second arc zone 6 for ultra-fine crushing. This staged crushing process can more effectively control the particle size distribution of the final product. Compared with traditional long-term, repetitive crushing, this device greatly improves working efficiency through a continuous and efficient crushing process. The raw material undergoes a complete and continuous crushing cycle from feeding to final discharge, avoiding the problem of multiple processing steps required to achieve the desired particle size in traditional methods. Due to the optimized crushing process, the entire crushing process is more stable and continuous, which not only improves efficiency but also reduces energy consumption. Compared with traditional methods, this continuous crushing method can achieve better crushing results with lower energy input. In summary, the technical solution of this non-metallic mineral ultra-fine crushing device not only solves the problems existing in traditional crushing methods but also significantly improves crushing efficiency, product quality, and economic benefits, representing a major innovation in the field of modern powder processing.

[0041] like Figures 5 to 7As shown, the roller 7 is hollow inside, and a support shaft 8 is coaxially arranged inside the roller 7. Multiple rotating rings 9 are rotatably arranged on the support shaft 8. Multiple first springs 10 are provided on the outer wall of each rotating ring 9. Multiple push plates 11 are slidably inserted on the outer circumference of the roller 7. The sliding direction of the push plates 11 is along the radial direction of the roller 7. One end of the push plate 11 extends outside the roller 7, and the other end of the push plate 11 extends inside the roller 7 and is connected to the first spring 10.

[0042] The end of the support shaft 8 passes through the roller 7 and the crushing box 1 and extends beyond the crushing box 1. The roller 7 rotates on the support shaft 8. The first spring 10 provides elastic thrust to the push plate 11. When the push plate 11 follows the roller 7 to the position of the extrusion zone 4, the push plate 11 extends and provides downward pressure to the raw material in the extrusion zone 4.

[0043] In detail, the first spring 10 provides an outward elastic thrust to the push plate 11. When the push plate 11 separates from the inner wall of the crushing chamber 1, that is, when the push plate 11 is located in the extrusion zone 4, the push plate 11 extends and slides outward. At this time, due to the rotation of the roller 7, the roller 7 will drive the push plate 11 to squeeze the raw material in the extrusion zone 4 downward, so that the outer wall of the roller 7 and the extrusion zone 4 can smoothly and directly and effectively crush the raw material, avoiding the situation where the outer wall of the roller 7 and the raw material are crushed when the roller 7 rotates alone. Slippage occurs between the rollers, causing the rollers 7 to be unable to provide effective extrusion force to the raw material. When the outer end of the push plate 11 contacts the inner wall of the extrusion zone 4, the inner wall of the extrusion zone 4 provides a pushing force to the push plate 11 and causes the push plate 11 to slide toward the inside of the rollers 7. The push plate 11 slides synchronously on the inner wall of the extrusion zone 4. When the push plate 11 moves with the rollers 7 to the position of the first arc zone 5 or the second arc zone 6, the inner walls of the first arc zone 5 and the second arc zone 6 also limit and extrude the push plate 11.

[0044] As the pusher plate 11 slides on the inner wall of the crushing chamber 1 while rotating with the roller 7, it can assist in pushing the raw materials on the inner wall of the crushing chamber 1, thereby moving the raw materials between the outer wall of the roller 7 and the inner wall of the crushing chamber 1. This allows the roller 7 to directly and effectively squeeze or crush the raw materials. At the same time, due to the pushing of the pusher plate 11, the raw materials will squeeze each other, thereby improving the crushing effect between the raw materials. When the roller 7 drives the pusher plate 11 to rotate, the pusher plate 11 will pull the rotating ring 9 to rotate on the support shaft 8 through the first spring 10. Even if the first spring 10 bends due to its elasticity, the bending elasticity of the first spring 10 can provide elasticity to the pusher plate 11.

[0045] like Figure 6 and Figure 9As shown, multiple toothed openings 12 are provided on the roller 7 between two adjacent push plates 11. The toothed openings 12 are connected to the inside of the roller 7. The multiple toothed openings 12 are parallel to each other. A filling plate 14 is slidably provided in each toothed opening 12. A base plate 13 is connected to the multiple filling plates 14. The base plate 13 is located inside the roller 7.

[0046] When the toothed opening 12 is located in the extrusion zone 4 or the first arc zone 5, the filling plate 14 is located inside the toothed opening 12. At this time, the edge of the toothed opening 12 on the outer wall of the roller 7 crushes the raw material. When the toothed opening 12 is located in the second arc zone 6, the end face of the filling plate 14 is coplanar with the outer wall of the roller 7, and the outer wall of the roller 7 forms a complete arc surface.

[0047] In detail, by setting the toothed opening 12, the raw material can be easily sheared and crushed through the edge of the toothed opening 12, thereby reducing the difficulty of crushing the raw material and increasing the crushing speed. When the toothed opening 12 moves to the position of the second arc-shaped area 6, in order to prevent powdery raw material from entering the toothed opening 12, the substrate 13 can push multiple filling plates 14 outward and make the outer wall of the roller 7 form a complete arc surface. In this way, the raw material can be directly crushed through the outer wall of the roller 7.

[0048] It should be noted that there is a base plate 13 between two adjacent push plates 11, and multiple filler plates 14 are disposed on the base plate 13. The multiple filler plates 14 are parallel to each other, so that when the base plate 13 moves, the multiple filler plates 14 can slide smoothly in the multiple toothed openings 12. The multiple filler plates 14 have different lengths, so that the multiple filler plates 14 can form a complete arc surface on the outer wall of the roller 7.

[0049] In actual use, since the filler plate 14 can slide inside the toothed opening 12, even if the raw material enters the toothed opening 12, the filler plate 14 can still push it out.

[0050] like Figures 7 to 8 As shown, a fixing ring 15 is fitted and fixed on the outer wall of the support shaft 8. Annular grooves are provided on both the front and rear sides of the fixing ring 15. The annular grooves are composed of a first arc-shaped groove 16 and a second arc-shaped groove 17. Multiple sliding columns 18 are slidably arranged in the annular grooves. The sliding columns 18 are connected to the base plate 13 by a connecting rod 19. When the sliding column 18 slides in the first arc-shaped groove 16, the filling plate 14 seals the toothed opening 12, and the outer wall of the roller 7 forms a complete arc surface. When the sliding column 18 slides in the second arc-shaped groove 17, the filling plate 14 slides into the toothed opening 12.

[0051] In detail, the radius of the first arc groove 16 is larger than the radius of the second arc groove 17. When the roller 7 rotates, it can drive the sliding column 18 to slide in the annular groove through the filling plate 14, the base plate 13 and the connecting rod 19. When the sliding column 18 slides in the first arc groove 16, the sliding column 18 pushes the base plate 13 and the filling plate 14 to move outward. The outer end of the filling plate 14 extends to the outer wall of the roller 7, and the outer wall of the roller 7 forms a complete arc surface. When the sliding column 18 slides in the second arc groove 17, the sliding column 18 pulls the filling plate 14 to slide into the toothed opening 12. At this time, the edge of the toothed opening 12 on the outer wall of the roller 7 is exposed.

[0052] like Figure 4 As shown, a circular opening is provided on the side wall of the crushing box 1;

[0053] The discharge structure 2 includes a discharge cylinder 20 connected to the circular opening. A support plate 21 is provided inside the discharge cylinder 20. A rotating shaft 22 is rotatably provided on the support plate 21. The rotating shaft 22 is connected to the roller 7 for transmission. Multiple fan blades 23 are provided on the outer wall of the rotating shaft 22.

[0054] In detail, the roller 7 can drive the rotating shaft 22 to rotate, thereby driving multiple fan blades 23 to rotate inside the discharge cylinder 20. The support plate 21 provides support for the rotating shaft 22. The fan blades 23 can draw air out of the crushing box 1 through the round opening, thereby sucking in the crushed ultrafine raw materials in the crushing box 1 and discharging them through the discharge cylinder 20 to the external collection device, thus realizing the output of raw materials. This method can also prevent the crushed raw materials in the crushing box 1 from being scattered randomly due to the rotation of the roller 7, making it convenient to collect the raw materials.

[0055] like Figure 4 As shown, the discharge cylinder 20 is in sliding contact with the crushing box 1, and the roller 7 is connected to the rotating shaft 22 through a transmission structure. The transmission structure includes a plurality of power rods 24 arranged in a ring. The power rods 24 are inclined along the axis of the rotating shaft 22. One end of the power rod 24 is rotatably mounted on the rotating shaft 22, and the other end of the power rod 24 is rotatably mounted on the roller 7.

[0056] In detail, both ends of the power rod 24 are connected to the roller 7 and the rotating shaft 22 respectively through rotating balls. When the roller 7 rotates, the equipment will vibrate. With the help of this vibration, the raw materials between the first arc-shaped area 5 and the roller 7 or between the second arc-shaped area 6 and the roller 7 in a small space can be crushed, thereby improving the crushing effect and crushing efficiency of the raw materials.

[0057] As the roller 7 rotates and the crushing box 1 vibrates, the crushing box 1 vibrates on a vertical plane perpendicular to the axis of the roller 7. To ensure the smooth output of the crushed raw materials, the discharge cylinder 20 is in contact with the crushing box 1. In this way, the vibration of the crushing box 1 has a smaller impact on the discharge cylinder 20. At this time, the roller 7 can pull the rotating shaft 22 to rotate with the help of multiple power rods 24, thereby providing power to the rotating shaft 22. Due to the vibration of the roller 7, the distance between the roller 7 and the rotating shaft 22 will change. Therefore, the power rods 24 need to be tilted. This can provide a buffer space for the vibration of the roller 7. Furthermore, the roller 7 is connected to the rotating shaft 22 through multiple power rods 24, thereby reducing the impact of vibration on the rotating shaft 22.

[0058] like Figure 4 As shown, the discharge cylinder 20 has a sliding opening, and a sliding column 25 is slidably disposed inside the sliding opening. The sliding column 25 is connected to the discharge cylinder 20 by a second spring 26.

[0059] The slide column 25 is provided with an inclined surface. When the slide column 25 slides in the sliding opening, the area of ​​the sliding opening blocking the inclined surface of the slide column 25 changes, and outside air can enter the discharge cylinder 20 through the gap between the sliding opening and the inclined surface.

[0060] In detail, the second spring 26 provides an outward elastic thrust to the slide column 25. In its natural state, the end of the slide column 25 blocks the sliding opening. When multiple fan blades 23 rotate, the air pressure inside the discharge cylinder 20 and the crushing box 1 decreases. In order to avoid the air pressure from squeezing and damaging the crushing box 1 and causing the inner wall of the crushing box 1 to directly rub against the roller 7, it is necessary to release the pressure of the crushing box 1 and the discharge cylinder 20. At this time, due to the action of air pressure, the slide column 25 can slide towards the discharge cylinder 20. A gap will be generated between the inclined surface on the slide column 25 and the sliding opening, so that the outside air can be replenished into the discharge cylinder 20 through the gap.

[0061] In actual use, due to the influence of ultrafine raw materials on the gap between the inner wall of the crushing box 1 and the end face of the roller 7, the amount of air flowing into the discharge cylinder 20 from the crushing box 1 will change constantly. Therefore, the air pressure in the discharge cylinder 20 will change at any time. At this time, the structure of the sliding column 25 and the second spring 26 can be used to stabilize the air pressure in the discharge cylinder 20.

[0062] like Figure 1 As shown, a transmission sleeve 28 is provided on the end face of the roller 7. The transmission sleeve 28 is sleeved on the outer wall of the support shaft 8 and passes through the crushing box 1. The end of the support shaft 8 is fixed to the outer wall of the crushing box 1 by a fixing plate 27. The fixing plate 27 is provided with a motor 29 and a transmission wheel 30 for providing power for the rotation of the transmission sleeve 28.

[0063] In detail, the motor 29 is fixed on the fixed plate 27, the transmission wheel 30 is installed on the output end of the motor 29, and the transmission wheel 30 is connected to the transmission sleeve 28. In this way, the motor 29 can provide rotational power to the roller 7 through the transmission wheel 30 and the transmission sleeve 28, while the fixed plate 27 provides support for the support shaft 8.

[0064] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
