Raw medicinal material screening device in traditional Chinese medicine pill preparation

Abstract

The invention discloses a raw medicinal material screening device in traditional Chinese medicine pill preparation. The raw medicinal material screening device comprises a screening barrel, a spiral blade, a drying structure and a collecting box. The screening barrel is in an inverted frustum shape, a cover plate is arranged on the top of the screening barrel and provided with a rotating motor and a feeding port, a vertically-arranged center column is arranged in the center of the screening barrel, and the top of the center column is connected with an output shaft of the rotating motor. The inner sides of the spiral blades are spirally downwards arranged around the central column, the outer sides of the spiral blades are rotationally matched with the inner wall of the screening barrel, the spiral blades are provided with a plurality of screening holes and racks, the racks are spirally arranged around the central column, and the spiral direction is the same as that of the spiral blades; the drying structure comprises an air pump, a ventilation pipe and a plurality of nozzles which are connected mutually, the ventilation pipe is spirally arranged around the side wall of the screening barrel, the spiral direction of the ventilation pipe is the same as that of the spiral blades, and the nozzles are arranged on the ventilation pipe; and the collecting box is arranged below the screening cylinder. The functions of multiple devices are integrated, meanwhile, the screening, drying and impurity removing effects are achieved, the cost is reduced, and the medicine processing rate is remarkably increased.

Description

technical field [0001] The invention relates to the technical field of medicinal material processing, in particular to a raw medicinal material screening device in the preparation of traditional Chinese medicine pills. Background technique [0002] The processing of traditional Chinese medicine pills generally goes through technological processes such as screening and removing impurities, cleaning and drying, chopping or crushing, mixing and sieving, and each step requires independent equipment to complete, such as dryers, shredders or powder mills. Machines, sieving machines, etc., each step is critical and will affect the uniformity and quality of the final drug. [0003] At present, when the factory is processing traditional Chinese medicine pills, the raw medicinal materials are crushed, and the magnetic impurities in the powder are adsorbed on the filter by using a magnetic filter. However, when the magnetic filter absorbs more impurities, the impurities cover the pores...

AI Technical Summary

Problems solved by technology

[0003] At present, when the factory is processing traditional Chinese medicine pills, the raw medicinal materials are crushed, and the magnetic impurities in the powder are adsorbed on the filter by using a magnetic filter. However, when the magnetic filter absorbs more impurities, the impurities cover the pores of the filter and affect the powder. Filtration rate; some use direct heating to dry the raw materials of medicines, which may cause the medicines to be heated unevenly, and the local temperature of the medicines is too high to cause denaturation of the medicines, affect the efficacy of the medicines, and the quality of the medicines is uneven; some technologies are advanced And chopping the original medicinal materials, and then drying, there is often a phenomenon that the medicinal powder sticks into agglomerates during drying, which will also lead to uneven drying of the medicinal powder; each device operates independently, and this technology has the problem of low production efficiency. Therefore, it is necessary to design a medicinal material processing device with assembly line operation and higher efficiency
