Stirring and drying device for medical pharmaceutical and chemical raw materials

Abstract

The invention discloses a stirring and drying device for medical pharmaceutical and chemical raw materials. The stirring and drying device comprises a raw material bin; a feeding hopper is arranged at the upper end of the raw material bin; a circulating feed port is formed in the lower right end of the raw material bin; an auger feeder is arranged in the raw material bin and is obliquely arranged; the right end of the auger feeder penetrates out of the raw material bin and is connected with a double-shaft stirring drier; the right end of the double-shaft stirring dryer is connected with a pneumatic dryer; the upper end of the pneumatic dryer is connected with a cyclone separator; the upper end of the cyclone separator is connected with an induced draft fan through an air flue; a star discharger is arranged at the lower end of the cyclone separator; a circulating conveyor belt is arranged at the lower end of the star discharger; and the right end of the circulating conveyor belt is inserted into the circulating feed port. The stirring and drying device has the advantages that the chemical raw materials are stirred through a double-shaft stirring mechanism, cyclone drying treatment is realized through the coordination of a rotating inverted cone and swirl vanes which are arranged at the bottom, then the final drying treatment is carried out through the cyclone separator, and therefore the stirring and drying effects can be improved, and the stirring and drying device is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of medical pharmaceutical and chemical raw material processing equipment, in particular to a stirring and drying device for medical pharmaceutical and chemical raw material. Background technique [0002] In the production and preparation process of medical pharmaceutical and chemical raw materials, stirring is an important process. Stirring is a kind of circulation through the stirrer, so that the gas, liquid and even suspended particles in the solution can be mixed evenly. In order to achieve this goal, it needs to be realized by means of forced convection and uniform mixing, that is, the internal components of the agitator. Stirring is a commonly used operation in organic preparation experiments. The purpose is to fully mix the reactants to avoid the occurrence of side reactions or the decomposition of organic matter due to uneven concentration of reactants and excessive localization and uneven heating.

Problems solved by technology

[0004] However, at present, many mixing and drying devices for chemical raw materials are processed at one time. Sometimes one-time stirring and drying cannot meet the required requirements, and the residual moisture in the interior may exceed the index, causing chemical raw materials to be easily wet and deteriorated during storage. It is easy to produce follow-up movement of raw materials, resulting in poor stirring and crushing performance, so a stirring and drying device for medical pharmaceutical and chemical raw materials is designed.
