A drying device for chemical raw materials and medicine

Abstract

The invention discloses a drying device for chemical raw materials and medicine. The drying device comprises a body which comprises a variable frequency motor, a feeding hole and a discharge hole. The base is arranged under the body; the variable frequency motor is arranged between the body and the base; the output part of the variable frequency motor is connected with a mixing shaft; the mixing shaft extends into the body; transverse mixing wheels are symmetrically arranged on the mixing shaft; the mixing shaft and the transverse stirring wheels are all of hollow structures; electric heating tubes are arranged inside the transverse stirring wheels and the mixing shaft; a screw scraper plate is further arranged on the mixing shaft; the feeding hole is formed in the top end of the body; a hot-air blower is connected with an air pipe arranged in the body by use of a guide pipe; a plurality of air holes are formed in the surface of the air pipe; a dry layer is arranged under the air pipe; an insulating layer is arranged on the inner wall of the body; an air pump is arranged on the outer surface of the body; the discharge hole is formed in the bottom of the body; a supporting bar is arranged between the body and the base. The drying device for chemical raw materials and medicine has the advantages of reasonable structural design, good drying effect, long service life and the like.

Description

technical field [0001] The invention relates to a drying device, in particular to a drying device for chemical raw materials and medicines. Background technique [0002] Drying technology has a wide range of applications. It is a cross-industry, interdisciplinary and experimental science technology. It is widely used in biology, medicine, health care, chemical industry, building materials, papermaking and pesticide industries, and drying is very important. The process is not only the solid-liquid separation process, but also the last process of production. The quality of the product also depends to a large extent on the comprehensive situation of drying technology and equipment use. However, the existing drying devices are not only expensive, but also the drying effect Poor, insufficient drying often occurs, and the service life is short. The Chinese patent literature discloses a dryer with application number CN201220582758.7, which is composed of a shell, a feed port and a ...

[0002] Drying technology has a wide range of applications. It is a cross-industry, interdisciplinary and experimental science technology. It is widely used in biology, medicine, health care, chemical industry, building materials, papermaking and pesticide industries, and drying is very important. The process is not only the solid-liquid separation process, but also the last process of production. The quality of the product also depends to a large extent on the comprehensive situation of drying technology and equipment use. However, the existing drying devices are not only expensive, but also the drying effect Poor, insufficient drying often occurs, and the service life is short. The Chinese patent literature discloses a dryer with application number CN201220582758.7, which is composed of a shell, a feed port and a discharge port. The device is heated by a heating tube, and the dryer is equipped with a heating roller and a heating disc on the heating roller to heat together to complete the drying of the material, but this structure design is relatively simple, and it is easy to cause insufficient drying. The situation, and the material is easy to accumulate, the local temperature is too high, the material is damaged due to high temperature, and it also leads to bad conditions such as poor drying efficiency.
