Detailed Implementation

[0049] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0050] like Figures 1 to 4 As shown, a traditional Chinese medicine ultrafine pulverization system includes:

[0051] Rack 1;

[0052] The crushing host 2 is fixedly placed on the frame 1; the crushing host 2 is provided with a crushing chamber 201, the side wall of the crushing host 2 is provided with a feed inlet, and the upper end face of the crushing host 2 is provided with a discharge outlet;

[0053] Rotating shaft 3, which is rotatably placed inside the crushing host 2;

[0054] The inner teeth 4 are fixedly placed inside the crushing chamber 201, and the inner teeth 4 are arranged in a ring structure along the inner wall of the crushing chamber 201.

[0055] The uniform air distribution blade 5 is arranged around the rotating shaft 3 and is fixedly placed at the bottom of the crushing chamber 201.

[0056] The movable gear disk 6 is fixedly mounted on the rotating shaft 3 and is located at the upper end of the wind distribution blade 5.

[0057] The grading impeller 7 is fixedly mounted on the rotating shaft 3, located at the upper end of the moving gear disk 6, and below the discharge port.

[0058] In this specific application, the Chinese medicinal materials to be pulverized are placed into the pulverizing chamber 201. The pulverizing host 2 introduces airflow, and the air distribution blades 5 disperse the airflow evenly. At the same time, the rotating shaft 3 rotates, driving the moving toothed disc 6 to rotate. During the rotation of the moving toothed disc 6, it works with the inner teeth 4 to pulverize the Chinese medicinal materials. The moving toothed disc 6 and the inner teeth 4 subject the raw materials of Chinese medicinal materials to high-speed impact and shearing. At the same time, the raw materials of Chinese medicinal materials are also pulverized by the high-frequency vibration generated by the eddy current. After pulverization, the Chinese medicinal materials are formed into Chinese medicinal material powder. During the rotation of the rotating shaft 3, the classifying impeller 7 also rotates. During the rotation of the classifying impeller 7, the Chinese medicinal material powder is sorted, and micron-sized Chinese medicinal material powder is sorted out. The micron-sized Chinese medicinal material powder is discharged through the discharge port on the upper end face of the pulverizing host 2 under the action of the dispersed airflow.

[0059] In this embodiment, the moving toothed disk 6 rotates in conjunction with the inner teeth 4 to pulverize the Chinese medicinal materials. It can pulverize extremely difficult-to-pulverize Chinese medicinal materials to the micron level, with the particle size of the Chinese medicinal material powder being between 10-100 μm. The air distribution blades 5 disperse the introduced airflow evenly, enabling the airflow to flow evenly upward from the bottom of the pulverizing chamber 201. The dispersed airflow can promote the uniform distribution of Chinese medicinal materials in the pulverizing chamber 201, improving the pulverizing efficiency and precision. The classifying impeller 7 sorts the Chinese medicinal material powder. By adjusting the rotation speed of the classifying impeller 7, the particle size of the Chinese medicinal material raw materials can be controlled, resulting in high sorting efficiency. The classifying impeller 7 and the moving toothed disk 6 are linked by the rotating shaft 3, which can effectively reduce the energy consumption required for sorting Chinese medicinal material powder.

[0061] In this specific application, when the internal teeth 4 and the moving toothed disc 6 of the pulverizer 2 work together to pulverize Chinese medicinal materials, the temperature of the pulverizer 2 rises. Excessive temperature of the pulverizer 2 can affect the heat-sensitive Chinese medicinal materials. Cooling water is injected into the water chamber through the water inlet 8 to cool the pulverizer 2. The cooled water is then discharged through the water outlet 9. This cooling process keeps the pulverizer 2 below the set temperature during the pulverization of Chinese medicinal materials, reducing the viscosity and heat sensitivity of the materials and improving pulverization efficiency. This method is suitable for pulverizing heat-sensitive Chinese medicinal materials, expanding its application range and ensuring the efficacy of the pulverized medicinal materials.

The first pulley and the second pulley are connected by a belt. During the rotation of the output end of the first motor 10, the rotating shaft 3 is driven to rotate through the first pulley, the belt, and the second pulley. During the rotation of the rotating shaft 3, the moving gear disk 6 and the classifying impeller 7 are driven to rotate. The rotation of the rotating shaft 3 through the first motor 10, the pulley, and the belt results in high transmission efficiency, enabling the rotating shaft 3 to rotate efficiently and smoothly.

The input end of the screw feeder 13 is connected to the output end of the gearbox 12 through a pulley and a belt.

[0069] In a specific application of this embodiment, the output end of the second motor 11 drives the screw feeder 13 to operate through the gearbox 12. The screw feeder 13 conveys the Chinese medicinal materials into the crushing chamber 201 of the crushing host 2. The screw feeder 13 conveys the Chinese medicinal materials with high conveying efficiency and easy-to-control conveying speed, thereby improving the crushing efficiency and crushing accuracy of the Chinese medicinal materials.

[0070] The above embodiments also include:

[0071] The hopper 14 is fixedly placed at the upper end of the screw feeder 13, and the discharge port at the lower end of the hopper 14 is connected to the feed end of the screw feeder 13.

[0073] In the above embodiment, an air inlet is provided on the front side wall of the pulverizing host 2, and a filter screen 15 is provided at the air inlet. The filter screen 15 is fixedly connected to the side wall of the pulverizing host 2.

[0074] In this specific application, the air inlet of the pulverizer 2 is connected to the pulverizing chamber 201. The air inlet introduces airflow into the pulverizing chamber 201, and the air distribution blades 5 disperse the airflow evenly. At the same time, the filter screen 15 filters the airflow to prevent dust or impurities in the airflow from mixing into the Chinese herbal medicine powder, thus ensuring the cleanliness of the Chinese herbal medicine powder.

[0075] The above embodiments also include:

[0076] Cyclone separator 16, the input end of which is connected to the discharge port of the crushing host 2 through a conveying pipe;

[0077] The first valve 17 is fixedly placed at the discharge port at the lower end of the cyclone separator 16;

[0078] The first spiral feeder 18 is fixedly placed at the lower end of the first valve 17, and the first spiral feeder 18 outputs the material at the bottom of the cyclone separator 16 by spiral.

[0079] In this specific application, the Chinese herbal medicine powder is discharged through the discharge port on the upper end of the pulverizing host 2 under the action of the dispersed airflow. The airflow carrying the Chinese herbal medicine powder enters the cyclone separator 16 through the conveying pipe. The powder with high density in the airflow is separated by cyclone in the cyclone separator 16 and falls to the bottom of the cyclone separator 16. By opening the first valve 17, the powder with high density at the bottom of the cyclone separator 16 is introduced into the first screw feeder 18. The first screw feeder 18 screws the powder with high density to the outside.

[0080] The cyclone separator 16 is used to recover the dense Chinese medicinal powder in the airflow, thereby improving the recovery efficiency of the Chinese medicinal powder; the first spiral feeder 18 can improve the convenience of Chinese medicinal powder recovery.

[0084] The second spiral feeder 21 is fixedly placed at the lower end of the second valve 20, and the second spiral feeder 21 outputs the material at the bottom of the bag collector 19 by spiral.

[0085] In this specific application, after the cyclone separator 16 recovers the high-density Chinese herbal medicine powder, the airflow enters the bag collector 19 through the conveying pipe. The airflow carries the low-density Chinese herbal medicine powder into the bag collector 19. The bag inside the bag collector 19 filters the Chinese herbal medicine powder in the airflow. The low-density Chinese herbal medicine powder adheres to the inner wall of the collecting bag. Within a set time, the high-pressure air of the bag collector 19 is opened and closed by the solenoid valve to vibrate the bag and shake off the Chinese herbal medicine powder adhering to the inner wall of the collecting bag to the bottom of the inner side of the bag collector 19.
