Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral processing technology, and in particular to a high-efficiency dry preparation device for pyrophyllite composite micro powder. Background Technology
[0002] Mineral processing refers to the technology and science of separating and enriching useful minerals from raw ores and removing impurities through physical, chemical or biological methods to obtain concentrates or materials that meet industrial needs. Among them, the high-efficiency pyrophyllite composite micro powder dry preparation device is a dry mechanical crushing system specifically designed for pyrophyllite mineral processing. Through a purely mechanical structure design including multi-stage crushing, static screening, precision classification and high-efficiency dust collection, it achieves continuous, low-energy consumption and high-purity preparation of pyrophyllite micro powder.
[0003] Because existing high-efficiency dry preparation equipment for pyrophyllite composite micro powder cannot discharge qualified powder or granules in a timely manner during material crushing, the qualified materials that are not discharged in time are repeatedly crushed, resulting in increased energy consumption and accelerated equipment wear. At the same time, the screening process of traditional preparation equipment is prone to dust overflow due to material spillage and screen vibration, which deteriorates the working environment. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing dry preparation device for pyrophyllite composite micro powder has the disadvantage that it cannot discharge qualified powder in time when the material is crushed, resulting in repeated crushing and increased energy consumption. To this end, we propose a high-efficiency dry preparation device for pyrophyllite composite micro powder.
[0005] To achieve the above objectives, this application adopts the following technical solution: a high-efficiency dry preparation device for pyrophyllite composite micro powder, comprising an outer barrel, four legs fixedly connected to the bottom of the outer barrel, a top cover installed on the top of the outer barrel, a crushing device installed at the bottom of the top cover, a motor installed on the top of the crushing device, two connecting blocks fixedly connected inside the outer barrel, a crushing chamber installed inside the outer barrel, a slot opened on the top of the connecting blocks, and two locking blocks fixedly connected to both sides of the top of the crushing chamber, the surface of the locking blocks engaging with the inside of the slots, circular grooves opened on both sides of the locking blocks, a first spring fixedly connected inside the circular grooves, a limit block fixedly connected to the other end of the first spring, circular holes opened on both sides of the connecting blocks, the surface of the limit block slidingly connected to the inside of the circular holes, and a push rod slidingly connected inside the circular holes.
[0006] Preferably, a limiting piece is fixedly connected to the surface of the limiting block, and the surface of the limiting piece is slidably connected to the inside of the circular groove.
[0007] Preferably, the top and bottom of the push rod surface are provided with sliding grooves, and the top and bottom of one side of the circular hole are fixedly connected with sliding blocks, and the surface of the sliding blocks is slidably connected to the inside of the sliding grooves.
[0008] Preferably, a second spring is slidably connected to the surface of the push rod, one end of the second spring is fixedly connected to one end of the push rod, and the other end of the second spring is fixedly connected to one end inside the circular hole.
[0009] Preferably, a load-bearing plate is fixedly connected to the inside of the outer barrel.
[0010] Preferably, a rubber pad is installed on the top of the load-bearing plate.
[0011] Preferably, the inner wall of the crushing chamber is an arc-shaped curved surface, and the screening holes are evenly distributed along the arc-shaped curved surface, so that the material contacts the screening holes along the arc trajectory during the crushing process.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, by placing the crushing chamber inside the outer barrel, pressing the limiting block returns it to the inside of the circular groove, and inserting the locking block into the slot, then releasing the pressing of the limiting block causes the first spring to automatically engage the limiting block and enter the circular hole, fixing the locking block inside the slot. This secures the crushing chamber inside the outer barrel. The crushing equipment is then started to crush the material inside the outer barrel. During crushing, pyrophyllite powder that reaches the required level automatically flows out from the gaps on the surface of the crushing chamber into the inside of the outer barrel, while pyrophyllite powder that does not meet the required level continues to be crushed inside the crushing chamber. When the crushing chamber needs to be removed from the outer barrel, press the push rod to push the limit block out of the circular hole. At this time, the limit of the jamming block is released, and the limit of the crushing chamber is also released. Then the crushing chamber can be removed from the outer barrel. This setting allows qualified particle size material to be discharged in time, reducing ineffective crushing and material accumulation in the chamber, reducing motor load and energy consumption. At the same time, the material in the crushing chamber enters the outer barrel directly through the screening hole, reducing dust leakage points in the traditional screening process. Combined with the sealing structure design, dust pollution is reduced and environmental performance is improved. Attached Figure Description

Detailed Implementation
[0020] 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.
[0021] Reference Figures 1-4As shown, this utility model provides a technical solution: a high-efficiency dry preparation device for pyrophyllite composite micro powder, including an outer barrel 1, four support legs 2 fixedly connected to the bottom of the outer barrel 1, a top cover 3 installed on the top of the outer barrel 1, a crushing device 4 installed and connected to the bottom of the top cover 3, a motor 5 installed on the top of the crushing device 4, two connecting blocks 6 fixedly connected inside the outer barrel 1, a crushing chamber 7 installed inside the outer barrel 1, a slot 8 opened on the top of the connecting blocks 6, and two locking blocks 9 fixedly connected to both sides of the top of the crushing chamber 7, the surface of the locking blocks 9 and the inside of the slot 8. The locking blocks 9 and 6 are interlocked. Both sides of the locking block 9 have circular grooves 10, and a first spring 11 is fixedly connected inside the circular groove 10. The other end of the first spring 11 is fixedly connected to a limiting block 12. Both sides of the connecting block 6 have circular holes 13. The surface of the limiting block 12 is slidably connected to the inside of the circular hole 13, and a push rod 14 is slidably connected inside the circular hole 13. By placing the crushing chamber 7 inside the outer barrel 1 and pressing the limiting block 12, the limiting block 12 returns to the inside of the circular groove 10, and the locking block 9 is inserted into the locking slot 8. Then, the pressing of the limiting block 12 is released. When the first spring 11 automatically abuts against the limiting block 12 and enters the interior of the circular hole 13, the locking block 9 is fixed inside the locking groove 8, thereby fixing the crushing chamber 7 inside the outer barrel 1. Then, the crushing equipment 4 is started to crush the material inside the outer barrel 1. During crushing, pyrophyllite powder that reaches the corresponding level automatically flows out from the gaps on the surface of the crushing chamber 7 into the interior of the outer barrel 1. Pyrophyllite powder that does not reach the corresponding standard continues to be crushed inside the crushing chamber 7. When it is necessary to remove the crushing chamber 7 from the interior of the outer barrel 1, the push rod 14 is pressed to push the material out of the outer barrel 1. Rod 14 pushes the limiting block 12, pushing the limiting block 12 out of the circular hole 13. At this time, the limiting of the locking block 9 is released, and the limiting of the crushing chamber 7 is also released. The crushing chamber 7 can then be removed from the inside of the outer barrel 1. This setting allows qualified particle size materials to be discharged in time, reducing ineffective crushing and material accumulation in the chamber, and reducing the load and energy consumption of the motor 5. At the same time, the material in the crushing chamber 7 enters the outer barrel 1 directly through the screening hole, reducing dust leakage points in the traditional screening process. Combined with the sealing structure design, dust pollution is reduced and environmental performance is improved.
[0022] Reference Figure 3 As shown in this embodiment: the surface of the limiting block 12 is fixedly connected to the limiting piece 15, and the surface of the limiting piece 15 is slidably connected to the inside of the circular groove 10. By setting the limiting piece 15, the movement position of the limiting block 12 can be restricted, and the limiting block 12 is prevented from being dislodged from the inside of the circular groove 10 due to the elasticity of the first spring 11, thus ensuring the stability of the connection between the locking block 9 and the crushing chamber 7.
[0023] Reference Figure 4As shown in this embodiment: sliding grooves 16 are provided at the top and bottom of the surface of the push rod 14, and sliding blocks 17 are fixedly connected to the top and bottom of one side of the circular hole 13. The surface of the sliding block 17 is slidably connected to the inside of the sliding groove 16. By making the sliding block 17 slide inside the sliding groove 16, the movement of the push rod 14 can be made more stable.
[0024] Reference Figure 4 As shown in this embodiment: a second spring 18 is slidably connected to the surface of the push rod 14. One end of the second spring 18 is fixedly connected to one end of the push rod 14, and the other end of the second spring 18 is fixedly connected to one end inside the circular hole 13. By setting the second spring 18, the movement of the push rod 14 can be effectively restricted, and the displacement of the push rod 14 caused by the vibration generated after the equipment is started can be avoided.
[0025] Reference Figure 5 As shown in this embodiment: a load-bearing plate 19 is fixedly connected inside the outer barrel 1. By installing the load-bearing plate 19 inside the outer barrel 1, the crushing chamber 7 is placed on top of the load-bearing plate 19, which can make the crushing chamber 7 more stable inside the outer barrel 1. The design of the load-bearing plate 19 can distribute the pressure of the crushing chamber 7 on the outer barrel 1, improve the load-bearing capacity of the equipment, and extend the service life of the equipment.
[0026] Reference Figure 5 As shown in this embodiment, a rubber pad 20 is installed on the top of the load-bearing plate 19. By installing the rubber pad 20 on the top of the load-bearing plate 19, the rubber pad 20 has good elasticity and wear resistance, which can effectively buffer the vibration generated during equipment operation, reduce noise pollution, protect the equipment from damage, and further improve the stability and durability of the equipment.
[0027] Reference Figure 2 As shown in this embodiment: the inner wall of the crushing chamber 7 is an arc-shaped curved surface, and the screening holes are evenly distributed along the arc-shaped curved surface, so that the material contacts the screening holes along the arc trajectory during the crushing process. This setting allows the material to flow naturally to the screening hole area during the crushing process, reducing material accumulation or dead corners in traditional straight cavities, ensuring that qualified particle size material passes through the screening holes in a timely manner, and avoiding over-crushing.
[0028] Working principle: By placing the crushing chamber 7 inside the outer barrel 1, pressing the limiting block 12 returns it to the inside of the circular groove 10, and the locking block 9 is inserted into the locking groove 8. Then, releasing the pressing of the limiting block 12 causes the first spring 11 to automatically abut against the limiting block 12 and enter the circular hole 13, fixing the locking block 9 inside the locking groove 8, thereby fixing the crushing chamber 7 inside the outer barrel 1. Then, the crushing equipment 4 is started to crush the material inside the outer barrel 1. Pyrophyllite powder that has reached the corresponding level of crushing automatically flows out from the gaps on the surface of the crushing chamber 7 into the inside of the outer barrel 1, while pyrophyllite powder that has not reached the corresponding standard is crushed. Crushing continues inside the crushing chamber 7. When it is necessary to remove the crushing chamber 7 from the outer barrel 1, press the push rod 14 to push the limiting block 12, pushing the limiting block 12 out of the circular hole 13. At this time, the limiting of the locking block 9 is released, and thus the limiting of the crushing chamber 7 is also released. At this time, the crushing chamber 7 can be removed from the outer barrel 1. This setting allows qualified particle size materials to be discharged in time, reducing ineffective crushing and material accumulation in the chamber, reducing the load and energy consumption of the motor 5. At the same time, the material in the crushing chamber 7 enters the outer barrel 1 directly through the screening hole, reducing dust leakage points in the traditional screening process. Combined with the sealing structure design, dust is reduced. To reduce pollution and improve environmental performance, the limiting plate 15 restricts the movement of the limiting block 12, preventing one end of the limiting block 12 from dislodging from the inside of the circular groove 10 due to the elasticity of the first spring 11. This ensures the stability of the connection between the locking block 9 and the crushing chamber 7. The sliding block 17 sliding within the sliding groove 16 further stabilizes the movement of the push rod 14. The second spring 18 effectively limits the movement of the push rod 14, preventing displacement caused by vibrations after equipment startup. A load-bearing plate 19 is installed inside the outer barrel 1, and the crushing chamber 7 is placed on top of the load-bearing plate 19 to ensure stable crushing. The crushing chamber 7 is more stable inside the outer barrel 1. The design of the load-bearing plate 19 can disperse the pressure of the crushing chamber 7 on the outer barrel 1, improve the load-bearing capacity of the equipment, and extend the service life of the equipment. By installing a rubber pad 20 on the top of the load-bearing plate 19, the rubber pad 20 has good elasticity and wear resistance, which can effectively buffer the vibration generated during the operation of the equipment, reduce noise pollution, protect the equipment from damage, and further improve the stability and durability of the equipment. This setting allows the material to flow naturally to the screening hole area during the crushing process, reducing the accumulation of material or dead corners in the traditional straight cavity, ensuring that qualified particle size material passes through the screening hole in time and avoiding over-crushing.
