Description

Technical Field

[0001] This invention patent relates to the technical field of traditional Chinese medicine manufacturing, and particularly to a granulator for traditional Chinese medicine granules. Background Art

[0002] Under the background of the country's strong advocacy for the development of the traditional Chinese medicine pharmaceutical industry, improving the production capacity of traditional Chinese medicine pharmaceutical enterprises and the quality of traditional Chinese medicine preparations has become the main goal of traditional Chinese medicine modernization. Therefore, the research and development of exclusive equipment suitable for the preparation of traditional Chinese medicine preparations is a powerful means to achieve this goal, and traditional Chinese medicine granulators are widely used in the traditional Chinese medicine industry.

[0003] In the process of traditional Chinese medicine granulation, the traditional Chinese medicine is mixed with excipients and then made into granules.

Under the action of the hot air inside, the powder is suspended in the granulation chamber, while the gelatinous medicine is transported through the second feed pipe. Under the action of compressed air and the nozzle, the gelatinous medicine is atomized into small particles and suspended in the granulation chamber. Due to the stirring blades arranged in the lower fluidization chamber, under the action of the stirring blades, the hot air inside rises and rotates at the same time, which can make the powder and the gelatinous small particles better adhere; since the traditional Chinese medicine powder is in a suspended state inside the granulation chamber, as the equipment runs for a longer time, the powder will easily adhere to the inner wall of the granulation chamber. Excessive powder adhesion will cause a certain degree of waste. The provided powder scraping assembly can effectively avoid the occurrence of such problems, and the entire equipment interior is connected. Part of the powder will enter the first ventilation pipe along with the hot air. The provided first filter plate can effectively intercept the powder, but it is easy to block the first filter plate as the powder increases, resulting in an increase in the internal pressure of the equipment. When the pressure increases to the limit value of the pressure gauge, the suction fan, the first control valve and the third control valve are closed, and the second control valve is opened. The hot air in the blower blows back the first filter plate through the third ventilation pipe to avoid the problem of equipment damage due to increased pressure. Description of the Drawings

[0028] Working principle: Rotate the fluidization chamber and the granulation chamber above the second ventilation chamber. Press down the first ventilation chamber until it is sealed through the lifting structure. Turn on the electric heating plate and the blower in the heating cylinder, and at the same time turn on the exhaust fan and the solenoid valve, so as to form a hot air circulation environment inside the whole device. At this time, the first control valve and the third control valve are in the open state, and the second control valve is in the closed state. The first feed pipe is connected to the powder medicine tank, and the second feed pipe is connected to the output port of the gelatinous medicine tank. At the same time, turn on the stirring motor and the external air compressor. Compressed air enters the second feed pipe through the air supply pipe, and then cooperates with the nozzle to atomize the gelatinous medicine into small particles. Under the blowing of the hot air in the lower fluidization chamber below, the small particle medicine box powder medicine is suspended in the granulation chamber, and after sufficient adhesion, it drops to the bottom of the second ventilation chamber due to the increased specific gravity. The air blown by the blower is heated by the heating plate and filtered through the second filter plate to ensure that the hot air entering the granulation chamber and other interiors is clean and pollution-free. At the same time, the exhaust fan sucks air at the top of the first ventilation chamber, so that the interior is always in a hot air circulation environment. The inside of the fluidization chamber is equivalent to a fluidized bed. Stirring blades are added in the fluidization chamber. On the one hand, it can increase the circulation of hot air inside. On the other hand, the prepared traditional Chinese medicine preparation is not easy to stick together under the stirring action of the stirring blades and can be scattered separately at the bottom of the second ventilation chamber; both the granulation chamber and the fluidization chamber are connected to the support frame through the rotating assembly. When opening for cleaning or inspection, only need to lift the upper second ventilation chamber and rotate it to carry out cleaning or inspection, which is convenient and simple to operate; when preparing the traditional Chinese medicine preparation, the powder medicine is sucked into the granulation chamber through the vacuum feeder set on the first feed pipe. Under the action of the internal hot air, the powder is suspended in the granulation chamber, while the gelatinous medicine is transported through the second feed pipe. Under the action of compressed air and the nozzle, the gelatinous medicine is atomized into small particles and suspended in the granulation chamber. Due to the stirring blades arranged in the lower fluidization chamber below, under the action of the stirring blades, the internal hot air rotates while rising, which can make the powder and the gelatinous small particles better adhere; since the traditional Chinese medicine powder is in a suspended state inside the granulation chamber, as the equipment runs for a longer time, the powder will easily adhere to the inner wall of the granulation chamber. Excessive powder adhesion will cause a certain degree of waste. The set powder scraping assembly can effectively avoid the occurrence of such problems, and the whole device interior is connected. Part of the powder will enter the first ventilation pipe along with the hot air. The set first filter plate can effectively intercept the powder. However, as the powder increases, it is easy to block the first filter plate, resulting in an increase in the internal pressure of the equipment. When it increases to the limit value of the pressure gauge, the exhaust fan, the first control valve and the third control valve are closed, and the second control valve is opened. The hot air in the blower blows back the first filter plate through the third ventilation pipe to avoid the problem of equipment damage due to increased pressure. The structure of this invention patent is simple, the operation is convenient, it can efficiently prepare traditional Chinese medicine preparations with uniform particles, and it is not easy to block the pipelines for transporting medicines in the equipment.
