Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine formula granulation technology, and in particular to a dry granulation machine for traditional Chinese medicine formula granulation. Background Technology

[0002] Traditional Chinese medicine often needs to have its moisture removed and be processed into suitable granules or powders for easy storage and use. Dry granulation machines are generally used for this process. The working principle of a dry granulation machine is to compress powdered materials with a moisture content of ≤5% into flakes or blocks through dry roller pressing technology. Then, after crushing, granulation, and screening processes, granulated materials that meet the requirements for use are finally obtained.

[0003] In the process of processing traditional Chinese medicine using existing dry granulation machines, a large amount of dust is often generated. With the accumulation of dust over a long period of time, due to the complex internal structure of the dry granulation machine, the accumulated dust is extremely difficult to remove. The accumulated dust will affect the normal operation of the granulation machine, increase the friction coefficient between rotating components, and hinder heat dissipation.

[0004] In the process of processing traditional Chinese medicine using existing dry granulation machines, a large amount of dust is often generated. The accumulated dust is extremely difficult to remove, which increases the friction coefficient between rotating components and does not facilitate heat dissipation. Therefore, a pneumatic dust collection structure is designed to overcome the above problems. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-9 This utility model provides an embodiment: a dry granulation machine for granulating traditional Chinese medicine formula granules, including an outer shell 1, a lower receiving chamber 9 and a side collecting box 13. The lower receiving chamber 9 is fixedly installed at the lower end of the outer shell 1 by bolts, and the side collecting box 13 is fixedly connected to one side of the outer shell 1. The side and lower end of the outer shell 1 are provided with pneumatic blowing components for discharging powdery residue. The surfaces of the lower receiving chamber 9 and the side collecting box 13 are provided with filter components for collecting traditional Chinese medicine granules and powdery residue.

[0026] Please see Figure 5 , Figure 7 and Figure 8In this embodiment, the upper end of the outer shell 1 is fixedly connected to the upper cover 2 by bolts. A motor 3 is fixedly installed on one side of the outer shell 1. A pressure roller 5 is rotatably connected inside the outer shell 1. The end of the pressure roller 5 is provided with a gear set 4, which is driven by the output shaft of the motor 3. A motor 6 is fixedly installed on one side of the outer shell 1. A crushing roller 8 is rotatably connected inside the outer shell 1. The end of the crushing roller 8 is provided with a gear set 7, which is driven by the output shaft of the motor 6. The crushing roller 8 is located below the pressure roller 5. The lower end of the lower storage compartment 9 is fixedly installed with a lower ventilation housing 10 by bolts. A pneumatic connector 3 17 is fixedly connected to the lower end of the lower ventilation housing 10. The lower end of the lower ventilation housing 10 is provided with a support foot. The lower ventilation housing 10 is used to blow up the powdery residue in the Chinese medicine granules. A side ventilation housing 11 is fixedly installed on one side of the housing 1. The side ventilation housing 11 is used to blow powdery residue to one side. A pneumatic connector 12 is fixedly connected to the side of the side ventilation housing 11. A filter screen 21 is fixedly installed on one side of the side collection box 13 by bolts. The side ventilation housing 11 has an opening on one side of the side collection box 13. The side ventilation housing 11 and the side collection box 13 are at the same height relative to the ground. The side collection box 13 is used to collect powdery residue. A filter screen 16 is fixedly connected to the lower end of the lower storage bin 9. A side cover 22 is fixedly installed on one side of the lower storage bin 9 by bolts. A side ventilation housing 24 is fixedly installed on the other side of the lower storage bin 9. A pneumatic connector 25 is fixedly installed on the side ventilation housing 24. The side ventilation housing 24 is used to blow Chinese medicine granules to one side.

[0027] Please see Figure 6 and Figure 9 In this embodiment, a positioning ring 18 is slidably connected to the surface of the pressure roller 5, and a fixing plate 19 is fixedly connected to one side of the positioning ring 18. A positioning handle 20 is threadedly connected to the fixing plate 19. A protrusion is provided on one side of the positioning ring 18, and arc-shaped grooves are evenly distributed on the surface of the pressure roller 5. The protrusion on the positioning ring 18 is adapted to the arc-shaped grooves on the surface of the pressure roller 5. The side of the protrusion on the positioning ring 18 is a slope. The protrusion on the positioning ring 18 is used to scrape off the excess material in the groove of the pressure roller 5.

[0028] During operation, motors 3 and 6 are started first. The medicinal materials to be processed are then poured into the feed inlet on the back of the outer casing 1. Motor 3 drives the pressure roller 5 to rotate via gear set 4. Under the pressure of the two pressure rollers 5, the medicinal materials are processed into easily cut flakes. The flakes then fall onto the crushing roller 8. Motor 6 drives the crushing roller 8 to rotate via gear set 7. The crushing roller 8 processes the flakes into the required granules. The pressure roller 5 and crushing roller 8 are commonly used processing tools in existing dry granulation technology. During the above processing, a large amount of dust residue is generated. This dust residue not only affects the health of workers but also accumulates inside the granulator, affecting its operation and being extremely difficult to clean. The air pump's air supply pipe is connected to pneumatic connectors 12, 15, and 17. The medicinal granules processed by the crushing roller 8 fall into the lower receiving bin 9, where they are filtered. The dust and residue that falls down from the filter screen 16 and into the lower collection bin 9 are blown upward by the lower ventilation housing 10 and separated from the Chinese medicine granules. Then, they are blown to one side by the side ventilation housing 11 into the side collection box 13 and filtered by the filter screen 21. This completes the collection of dust and residue. When it is necessary to remove the Chinese medicine granules from the lower collection bin 9, open the flow limiting valve of the pneumatic connector 25, remove the side cover 22, and the airflow from the side ventilation housing 24 will blow the material in the lower collection bin 9 out of the lower collection bin 9. This can quickly complete the collection of Chinese medicine granules. During long-term use, residue will accumulate in the arc-shaped recess of the pressure roller 5, affecting the normal operation of the pressure roller 5. When cleaning is required, loosen the positioning handle 20, and then push the positioning handle 20. The positioning ring 18 slides on the surface of the pressure roller 5, and the protrusion on the positioning ring 18 scrapes off the accumulated residue in the groove of the pressure roller 5, thereby realizing the rapid removal of the accumulated residue.

[0029] Through the above steps, during the processing of Chinese medicine granules, the granulator uses a pneumatic blowing component to separate the useless dust residue from the granules and blow the dust residue into the side collection point. This prevents the dust residue from flowing out and being inhaled by the workers, as well as from accumulating inside the granulator and affecting its normal operation. Furthermore, when collecting the processed Chinese medicine granules, the pneumatic component can quickly discharge the granules, thus completing the collection of the finished product.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
