Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine pulverization technology, and in particular to an adjustable powder-selecting ultrafine pulverizer for crushing medicinal materials. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to substances used for the prevention, treatment, and diagnosis of diseases, and also possessing rehabilitative and health-preserving effects, under the guidance of TCM theory. TCM mainly originates from natural medicines and their processed products, including plant-based, animal-based, and mineral-based medicines, as well as some chemical and biological products. To better apply TCM in bioengineering and pharmaceutical engineering, the medicinal materials need to be pulverized to provide raw materials for preparing various dosage forms, such as powders, granules, pills, and tablets.

[0003] Existing common pharmaceutical pulverizing equipment has a simple structure, mostly adopting a single pulverizing chamber structure (such as hammer mill) or a simple series pulverizing-separation design. In use, traditional equipment can only achieve ultrafine pulverization through one pulverization or mechanical reprocessing, resulting in the finished product containing coarse particles, which affects the bioavailability of drugs. At the same time, although some equipment has added cyclone separators, the sorting mechanism and the pulverizing unit operate independently. The coarse powder after sorting needs to be manually returned, and the fine powder is directly collected through the external discharge pipe, causing the active ingredients to escape and the production continuity to be interrupted, leading to repeated processing of medicinal materials and a surge in energy consumption, which seriously restricts the large-scale application in pharmaceutical engineering. Utility Model Content

[0028] Example 1

[0029] like Figures 1-4As shown, an adjustable ultrafine pulverizer for crushing medicinal materials includes a grinding mechanism 3. In this embodiment, the grinding mechanism 3 includes a main cylinder 31, and a conical grinding wall 32 is fixedly provided on the side wall of the main cylinder 31. A first driving member 30 is provided in the middle of the outer part of the main cylinder 31. A first rotating shaft 34 passes through the output end of the first driving member 30. The first rotating shaft 34 passes through the main cylinder 31 and is fixedly sleeved with a conical grinding disc 33. The conical grinding disc 33 and the conical grinding wall 32 form a grinding gap. During use, the medicinal material particles from the pulverizing process enter the grinding gap and are ultrafinely pulverized under the action of the conical grinding disc 33 and the conical grinding wall 32. In order to ensure that the medicinal material particles can smoothly enter the grinding gap, a conical guide cylinder 35 is provided at the upper end of the conical grinding disc 33, and the height of the conical grinding disc 33 is greater than the height of the conical grinding wall 32.

[0030] The pulverizing mechanism 2 is fixedly installed above the grinding mechanism 3 and is connected to the feed inlet of the grinding mechanism 3. Specifically, in this solution, the pulverizing mechanism 2 adopts existing medicinal material pulverizing equipment. The built-in pulverizing disc is existing technology and will not be described in detail here. It is only necessary to connect the feed end of the pulverizing mechanism 2 to the feed mechanism 1 and the discharge end to the grinding mechanism 3.

[0031] The feeding mechanism 1 is obliquely arranged at the feed inlet of the crushing mechanism 2 and is used to transport materials into the crushing mechanism 2. Specifically, the feeding mechanism 1 includes a feeding trough 10 and a feeding cylinder 11. The feeding trough 10 is a box structure with an open top. The inside of the feeding cylinder 11 is provided with a feeding channel. One end of the feeding cylinder 11 is provided with a third driving member 12, and a third rotating shaft 13 and a conveying blade are arranged through the middle. The upper side wall of the feeding cylinder 11 is provided with a discharge cylinder 15, and the lower end of the discharge cylinder 15 is connected to the feed inlet of the crushing mechanism 2.

[0032] To further improve the stability of the medicinal materials during transport, the feeding channels are configured as two interconnected sets, namely the first feeding channel 101 and the second feeding channel 102; the diameter of the first feeding channel 101 is smaller than that of the second feeding channel 102; the third rotating shaft 13 passes through the feeding cylinder 11 and is fitted with a variable diameter spiral conveying blade 16; the lower side wall of the feeding cylinder 11 is provided with a feeding slot 14; by using the variable diameter spiral conveying blade 16, it is possible to ensure that the medicinal materials about to fall into the pulverizing mechanism 2 are arranged tightly, thereby improving the pulverizing effect of the pulverizing mechanism 2.

[0033] The fractionation mechanism 4 is fixedly installed at the bottom of the grinding mechanism 3 and communicates with the discharge port of the grinding mechanism 3. Specifically, the fractionation mechanism 4 includes a cylindrical body 41, a second driving member 42 is installed on the outside of the cylindrical body 41, and a second rotating shaft 43 is installed at the output end of the second driving member 42. The second rotating shaft 43 passes through the cylindrical body 41 and is fitted with fractionation blades 44. The fractionation blades 44 consist of six groups of blades of the same specification evenly arranged at a 60° angle, with adjacent blades forming a receiving groove, which facilitates the transportation of the ground medicinal materials to the sorting process and avoids the medicine clogging the sorting plate 53.

[0034] The sorting mechanism 5 is fixedly installed at the bottom of the fractionation mechanism 4 and communicates with the discharge port of the fractionation mechanism 4. The sorting mechanism 5 includes a conical cylinder 51, and a sorting plate 53 is inclinedly arranged inside the conical cylinder 51. The port of the guide cylinder 52 is located at the lower end of the sorting plate 53. The storage tank 9 is located outside the sorting mechanism 5 and communicates with the side discharge port of the sorting mechanism 5 through the guide cylinder 52. The negative pressure pipe 91 has a negative pressure fan 90, one end of which is located inside the storage tank 9 and the other end is located above the inside of the grinding mechanism 3. In use, the ground material falls onto the sorting plate 53 under the rotation of the fractionation blades 44. The qualified fine powder passes through the sieve holes and enters the cyclone separator 8 for collection. The coarse powder slides along the inclined plate into the guide cylinder 52 and is temporarily stored in the storage tank 9. When the negative pressure fan 90 is started, the coarse powder in the storage tank 9 is sucked into the top of the grinding mechanism 3 through the pipe 91 to realize automatic return and re-grinding.

[0035] A cyclone separator assembly is located at the bottom of the sorting mechanism 5 and is connected to the bottom discharge port of the sorting mechanism 5 for sorting materials. The cyclone separator assembly includes an air source device 6 and a cyclone separator 8. An air pipe 7 is provided between the air source device 6 and the cyclone separator 8. The discharge port of the sorting mechanism 5 is sealed and connected to the middle of the air pipe 7. Preferably, an inclined guide plate is also provided at the connection between the air pipe 7 and the sorting mechanism 5. In this solution, the air source device 6 can be a fan, compressor, or other air supply equipment, the purpose of which is to blow the material in the air pipe 7 into the cyclone separator at high speed.

[0036] It is worth noting that the drive component in this solution is preferably a variable frequency motor, or it can be a combination of a motor and a gearbox, in order to adjust the speed appropriately according to the crushing requirements.

[0037] The working process of this device

[0038] Feeding and coarse crushing: The medicinal materials enter the inclined feeding cylinder 11 through the feeding trough 10 and are adaptively pushed to the crushing mechanism 2 by the variable diameter spiral blades 16; the crushing mechanism 2 crushes the material into granules. The coarsely crushed particles fall into the grinding mechanism 3 and are crushed to the target particle size in the gap between the conical grinding disc 33 and the grinding wall 32; after crushing, the material is uniformly output at a fixed flow rate by the blades 44 of the dispensing mechanism 4 to avoid overloading the sorting mechanism 5. The material is screened on the sorting plate 53, and the qualified fine powder passes through the screen holes and enters the cyclone separator 8 for collection; the coarse powder slides along the inclined plate into the guide cylinder 52 and is temporarily stored in the storage box 9; when the negative pressure fan 90 is started, the coarse powder in the storage box 9 is sucked into the top of the grinding mechanism 3 through the pipe 91 to realize automatic return and re-crushing. At the same time, the negative pressure pipe 91 maintains a slight negative pressure environment at the top of the grinding chamber to prevent the fine powder from escaping; the dust-laden airflow is collected after centrifugation in the cyclone separator 8, completing the ultra-fine crushing function of the medicinal material powder.

[0039] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
