Description

Technical Field

[0001] This utility model relates to the field of pulverizing equipment technology, specifically to an ultrafine pulverizing device. Background Technology

[0002] An ultrafine pulverizer is a device that uses air separation, heavy-pressure grinding, and shearing to achieve ultrafine pulverization of dry materials. It is widely used in various industries such as traditional Chinese medicine, Western medicine, pesticides, biology, cosmetics, food, feed, chemicals, and ceramics. It is particularly effective for pulverizing fibrous, high-toughness, high-sugar, and high-fiber materials, such as cordyceps, tea, and lingzhi. The working principle of an ultrafine pulverizer is mainly based on mechanisms such as impact, collision, and shearing. Through the interaction between high-speed rotating blades or grinding wheels and the material, the material is pulverized to an extremely fine particle size.

[0003] A search of CN221619589U reveals a technology related to powder powder production, specifically an ultrafine pulverizing device for powder powder production. Technical Problem: Existing ultrafine pulverizing devices for powder powder production suffer from low pulverizing force and efficiency. Technical Solution: An ultrafine pulverizing device for powder powder production includes a pulverizing component, a drive motor, and a base; drive motors are located on both sides of the pulverizing component; a base is located at the lower end of the pulverizing component and drive motors. This invention significantly improves the efficiency of ultrafine pulverization by using a pulverizing wall and multi-bladed pulverizing rollers for grinding and crushing, preventing fragments from getting stuck in the gaps of the pulverizing structure. This solves the problem of high processing difficulty for ultrafine particles caused by the low pulverizing force of existing ultrafine pulverizing devices for powder powder production.

[0004] However, during the crushing process, large and small particles of raw materials will mix together, and both types of raw materials will be subjected to ultra-fine crushing at the same time, which will greatly affect the crushing efficiency and crushing quality.

[0005] Secondly, it is not convenient to quantitatively control the amount of raw materials input. If a large amount of raw materials are input at the same time, it is easy to cause blockage or even damage the machine. Therefore, this needs to be improved. Utility Model Content

[0015] Beneficial effects

[0016] This utility model provides an ultrafine pulverizing device, which has the following beneficial effects:

[0017] 1. This ultrafine pulverizing device, by setting up a classification and pulverizing mechanism, uses a drive rod to drive multiple screens to rotate, allowing small particles of raw material to fall from the first hole and preferentially enter the ultrafine pulverizer through the guide hopper for ultrafine pulverizing. Subsequently, large particles of raw material fall from the second hole, and with the help of the guide plate, the large particles of raw material are concentrated. Then, by using two pulverizing rollers to rotate, the large particles of raw material can be pulverized into small particles, which are then allowed to enter the ultrafine pulverizer through the guide hopper for ultrafine pulverizing. This effectively avoids the problem of large and small particles of raw material mixing together, which would greatly affect the raw material pulverizing efficiency and pulverizing quality.

[0018] 2. This ultrafine pulverizing device, through the setting of a feeding mechanism, uses a hydraulic telescopic rod to perform regular reciprocating motion, which can drive an L-shaped pusher plate to move back and forth in the feeding box. When the L-shaped pusher plate moves to the leftmost end, the raw material will enter the feeding box from the loading hopper. When the L-shaped pusher plate moves to the rightmost end, it can quantitatively push the raw material entering the feeding box into the screening cylinder, thereby realizing the intermittent quantitative delivery of raw material into the screening cylinder, effectively avoiding the situation where a large amount of raw material is put in, which may cause blockage or even damage to the machine.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Please see Figure 1-4This utility model provides a technical solution: an ultra-fine pulverizing device, including an ultra-fine pulverizer 1, a guide hopper 2 is provided at the upper feed inlet of the ultra-fine pulverizer 1, a classification pulverizing mechanism 3 is fixedly connected to the upper end of the guide hopper 2, a feeding mechanism 4 is provided on the left side of the classification pulverizing mechanism 3, and a loading hopper 5 is provided on the upper surface of the feeding mechanism 4.

[0026] The sorting and crushing mechanism 3 includes a screening cylinder 6, multiple screens 7, a drive rod 8, a crushing box 9, a partition plate 10, two guide plates 11, and two crushing rollers 12. The crushing box 9 and the partition plate 10 are fixedly connected to the lower surface of the screening cylinder 6. The drive rod 8 is rotatably connected to the inner wall of the screening cylinder 6. The multiple screens 7 are arranged in a ring array and fixedly connected to the outer surface of the drive rod 8. The upper ends of the two guide plates 11 are fixedly connected to the partition plate 10 and the crushing box 9, respectively. The two crushing rollers 12 are rotatably connected to the inner wall of the crushing box 9. The surface of the screening cylinder 6 has a first drain hole 13 and a second drain hole 14 located on both sides of the partition plate 10. The diameter of the first drain hole 13, the mesh diameter of the screen 7, and the... The diameter of the second discharge hole 14 gradually increases. By setting up a classification and crushing mechanism 3, and using the drive rod 8 to drive multiple screens 7 to rotate, small particles of raw material can fall from the first discharge hole 13 and enter the ultrafine pulverizer 1 through the guide hopper 2 for ultrafine crushing. Subsequently, large particles of raw material will fall from the second discharge hole 14. With the help of the guide plate, the large particles of raw material are concentrated. Then, by using the rotation of two crushing rollers 12, the large particles of raw material can be crushed into small particles, which are then allowed to enter the ultrafine pulverizer 1 through the guide hopper 2 for ultrafine crushing. This effectively avoids the problem of large and small particles of raw material mixing together, which would greatly affect the crushing efficiency and crushing quality.

[0027] A dust cover can be added to the surface of the hopper 5 to prevent dust from entering the raw materials and causing contamination.

[0028] The feeding mechanism 4 includes an L-shaped push plate 15, a hydraulic telescopic rod 16, and a feeding box 17. The lower end of the hopper 5 is connected to the feeding box 17, and the right end of the feeding box 17 is connected to the screening cylinder 6. The hydraulic telescopic rod 16 is fixedly connected to the inner wall of the feeding box 17, and the L-shaped push plate 15 is fixedly connected to the end of the hydraulic telescopic rod 16. The L-shaped push plate 15 is slidably connected to the inner wall of the feeding box 17. By setting the feeding mechanism 4, the hydraulic telescopic rod 16 can perform regular reciprocating motion, which can drive the L-shaped push plate 15 to move back and forth in the feeding box 17. When the L-shaped push plate 15 moves to the leftmost end, the raw material will enter the feeding box 17 from the hopper 5. When the L-shaped push plate 15 moves to the rightmost end, it can push the raw material that has entered the feeding box 17 into the screening cylinder 6 in a quantitative manner, thereby realizing the intermittent quantitative delivery of raw material into the screening cylinder 6, effectively avoiding the situation where a large amount of raw material is put in, causing blockage or even damage to the machine.

[0029] A motor bracket is fixedly connected to the outer surface of the screening cylinder 6. A servo motor 18 is fixedly connected to the surface of the motor bracket, and the output end of the servo motor 18 is connected to the drive rod 8.

A transmission belt 21 is fitted on the outer surfaces of the first pulley 19 and the second pulley 20. A transmission gear 22 is fixedly connected to the rear end of each of the two crushing rollers 12, and the two transmission gears 22 mesh with each other. When the servo motor 18 works, it can drive the second pulley 20 to rotate. The transmission belt 21 drives the first pulley 19 to rotate, thereby driving one of the crushing rollers 12 to rotate. Finally, the two transmission gears 22 mesh with each other, so that the two crushing rollers 12 can rotate synchronously in opposite directions.

[0030] Both the feeding mechanism 4 and the ultrafine pulverizer 1 are fixedly connected to support legs 23, which can support the feeding mechanism 4 and the ultrafine pulverizer 1.

[0031] Working Principle: When this ultrafine pulverizing device is in use, the raw material is first fed into the loading hopper 5. The hydraulic telescopic rod 16 reciprocates, driving the L-shaped pusher plate 15 to move back and forth within the feeding box 17. When the L-shaped pusher plate 15 moves to the leftmost position, the raw material enters the feeding box 17 from the loading hopper 5. When the L-shaped pusher plate 15 moves to the rightmost position, it quantitatively pushes the raw material into the screening cylinder 6, thus achieving intermittent quantitative feeding of raw material into the screening cylinder 6. This effectively avoids blockages or even machine damage caused by excessive raw material input. After the raw material enters the screening cylinder 6, a servo motor... The operation of the 18 mechanism can drive the drive rod 8 to rotate, which in turn drives multiple screens 7 to rotate. This allows small particles of raw material to fall through the first hole 13 and preferentially enter the ultrafine pulverizer 1 through the guide hopper 2 for ultrafine pulverization. Subsequently, large particles of raw material will fall through the second hole 14. With the help of the guide plate, the large particles of raw material are concentrated, and then the two pulverizing rollers 12 are rotated to pulverize the large particles of raw material into small particles, which are then allowed to enter the ultrafine pulverizer 1 through the guide hopper 2 for ultrafine pulverization. This effectively avoids the mixing of large and small particles of raw material, which would greatly affect the pulverization efficiency and pulverization quality.
