Embodiment 1

[0033] See figure 1 , A device for ultrafine pulverization and classification of capsule drugs, comprising an air source system, an ultrafine pulverization mechanism connected with the air source system, a classification mechanism connected with the ultrafine pulverization mechanism, and a collection mechanism connected with the classification mechanism,

[0034] The air source system includes an oil-free air compressor 1, an air storage tank 2 connected to the oil-free air compressor, and an air cooling dryer 3 connected to the air storage tank. The air cooling dryer is connected to the crushing mechanism.

[0035] The ultrafine grinding mechanism includes a feeder 4, an ultrafine grinding chamber 5 connected with the feeder, and a discharge port 1 connected with the ultrafine grinding chamber.

[0036] The grading mechanism includes a grading chamber 6, a grading wheel arranged inside the grading chamber, a motor 7 connected to the grading wheel, and a discharge port 8 arranged at t...

Embodiment 2

[0048] Refer to figure 1 , This embodiment is a device for superfine pulverization and classification of capsule medicines. The difference from embodiment 1 is:

[0049] The induced draft fan is connected to the muffler 21.

[0050] The induced draft fan adopts the HTD series high-pressure fan, and chooses the axial intake, single-stage cantilever centrifugal blower. The fan has the characteristics of high pressure, large air volume, low noise, stable operation, and long service life. Compared with other fans, it can save 20- 50%, the noise is lower than 75dB, saving various costs by 30-45%. The function of the induced draft fan is to provide suitable and stable centripetal force for the grading mechanism, dissipate heat in time, generate negative pressure in the system, and prevent external leakage of powder.

Embodiment 3

[0052] Refer to figure 2 In this embodiment, a device for superfine pulverization and classification of capsule drugs is an improvement on the basis of embodiment 2, specifically:

[0053] The gas storage tank is connected to the air refrigerating and drying machine through a gas conveying pipe 14 and an air filter 15 is arranged on the gas conveying pipe 1.

[0054] Through the above technical solution, the air can be purified once, and the impurities in the air can be prevented from affecting the cooling and drying efficiency of the air cooling and drying machine.

[0055] According to the actual needs of the present invention, an automatic drain is added to the air filter to remove the condensed water that may be generated at the bottom of the air filter.

Abstract

The invention provides an ultrafine pulverizing and grading device for a capsule drug and a technical method thereof, and belongs to the technical field of pulverizing devices. The device comprises anair source system, an ultrafine pulverizing mechanism, a grading mechanism and a collecting mechanism, wherein the air source system comprises an oil-free air compressor, an air storing tank which isconnected to the oil-free air compressor, and an air freezing dryer which is connected to the air storing tank; the air freezing dryer is connected to the pulverizing mechanism; the ultrafine pulverizing mechanism comprises a feeder, an ultrafine pulverizing chamber which is connected to the feeder, and a first discharging port which is connected to the ultrafine pulverizing chamber; the gradingmechanism comprises a grading chamber, a grading wheel which is arranged in the grading chamber, a motor which is connected to the grading wheel, and a second discharging port which is formed in the upper part of the grading chamber; the collecting mechanism comprises a cyclone collector which is connected to the second discharging port, and a pulse reverse-blowing cloth dust collector which is connected to the cyclone collector; and the pulse reverse-blowing cloth dust collector is connected to an induced draft fan. The device is novel in structure, reasonable in design, capable of pulverizing, grading and collecting the drug in one time, and free from dust pollution.

Description

Technical field [0001] The invention belongs to the technical field of pulverization devices, and specifically relates to a capsule drug ultrafine pulverization and classification device and a process method thereof. Background technique [0002] Capsules refer to solid preparations made by filling hollow hard capsules or sealing soft capsule materials with medicines or suitable auxiliary materials. They can be divided into hard capsules, soft capsules (capsules), sustained-release capsules, controlled-release capsules and intestines. Dissolving capsules, mainly for oral use. The rate of drug absorption is affected by the solubility and dissolution rate of the drug in the body fluid of the absorption site. The dissolution rate is directly proportional to the surface area of ​​the drug. For the same amount of drug, the smaller the particle size and the larger the surface area, the better the dissolution and absorption of the drug. Therefore, it is of great significance to apply ...
