Description

Air regulating valve group and Chinese herbal medicine drying system with adjustable working mode Technical Field The utility model belongs to the technical field of traditional Chinese medicine processing equipment, relates to a wind regulating valve and a Chinese herbal medicine dryer, and particularly relates to a wind regulating valve group and a Chinese herbal medicine drying system with an adjustable working mode. Background The Chinese herbal medicine dryer is a common device for drying Chinese herbal medicines, and the forms of the Chinese herbal medicines include but are not limited to pills and decoction pieces, and a set of Chinese herbal medicine drying system is formed by connecting parts such as a radiator, a cyclone separator, a wind conveying pipeline and the like. The existing Chinese herbal medicine drying system needs drying equipment with different working modes according to different water contents of Chinese herbal medicines to be processed. The existing drying arrangement is divided into a self-circulation type drying system and a direct-discharge type drying system according to different working modes, when the water content of the materials to be processed is small and the humidity is small, the self-circulation type drying system is needed, and when the water content of the materials to be processed is large and the humidity is large, the direct-discharge type drying system is needed to avoid moisture aggregation in a dryer. The self-circulation type drying system is characterized by also comprising a hot air circulation system, wherein the hot air circulation system comprises an air inlet end and an air outlet end, drying hot air is circularly conveyed in the drying machine box for pill drying, a hot air pipe is arranged in the roller, the hot air pipe is communicated with the air inlet end of the hot air circulation system, and the hot air pipe conveys the drying hot air into the roller. The arrangement of the hot air circulation system improves the utilization rate of the dry hot air resources. A direct-discharge type drying system, such as the Chinese patent publication No. CN222438358U, is characterized by that it includes a machine box, in the machine box a drum and a supporting frame are set, the drum is positioned on the upper portion of supporting frame, the bottom of machine box is equipped with a rotatable bottom plate, two ends of machine box are respectively equipped with a feeding cover and a discharging cover, the upper portion of rotatable bottom plate is equipped with a cylinder, the upper end of cylinder is fixedly connected with supporting frame, the lower end is rotatably connected with rotatable bottom plate, the top of machine box is equipped with an upper air-out pipe, the supporting frame is equipped with upper hot air partition plate, lower hot air partition plate and coaming, the upper hot air partition plate and lower hot air partition plate are respectively and slidably matched with drum, the coaming is positioned between upper hot air partition plate and lower hot air partition plate and under drum, the drum is equipped with uniformly-distributed air inlet channel, and the supporting frame is equipped with motor, lower air-out pipe and air inlet pipe. The dynamic airflow dryer for the traditional Chinese medicine decoction pieces has the advantages of capability of entering and exiting hot airflow of a roller, quick heat exchange and dehumidification, natural and proper drying temperature and air pressure, good drying quality of the decoction pieces, automatic operation, high efficiency and high practical value and popularization value. The hot air in the case of the patent dryer is directly discharged through the air outlet and does not enter the case of the dryer any more, so that the moisture in the case can be brought out, and the drying efficiency is improved. At present, in order to process Chinese herbal medicines with different water contents, chinese medicine production enterprises need to purchase drying systems with different forms respectively, so that the production cost of the enterprises is increased, the sites in production workshops are occupied, and the cost control and workshop planning of the enterprises are not facilitated. In view of this, in order to meet the production needs of enterprises, it is necessary to design a Chinese herbal medicine drying system capable of adjusting the working modes according to materials with different water contents. Disclosure of Invention The utility model aims to overcome the defects of the prior art and provide a pill drying system which has scientific and reasonable structural design, adjustable working mode, convenient operation, production requirement satisfaction and easy processing. The utility model solves the technical problems by adopting the following technical scheme: The air regulating valve group is characterized by comprising a valve body shell, a valve plate and a driving mechanism,
