A vacuum drying kettle for fine chemical production

Abstract

A vacuum drying kettle for fine chemical production, comprising a kettle body, a motor reduction mechanism, a conveyor belt, a driving pulley, a driven pulley, a support plate, a support frame, a solenoid valve, a regulated power supply, an electric heating tube, a power switch, Pressure switch; also has detection mechanism, temperature control mechanism, power supply mechanism; motor deceleration mechanism, conveyor belt, driving pulley, driven pulley, support plate, support frame, solenoid valve, stabilized power supply, electric heating tube, power switch, The pressure switch, detection mechanism, temperature control mechanism, power supply mechanism and the kettle body are installed together. Under the action of the relevant mechanism, the present invention can continuously drive the kettle body to rotate during operation, thereby ensuring that the products in the kettle body are uniformly heated, and because no relevant parts are located in the kettle body, it prevents the vibration caused by the product adhering to the whole equipment during operation, and ensures The effective volume of the kettle body is increased, and the work efficiency is improved. Based on the above, the present invention has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a vacuum drying kettle for fine chemical production. Background technique [0002] The vacuum drying kettle is specially designed for drying heat-sensitive, easily decomposed and easily oxidized substances (such as fine chemical products), and can quickly dry some items with complex components. When the existing vacuum drying kettle is working, hot water or low-pressure steam is passed into the reaction kettle body as a heating medium to heat the product in the reaction kettle body, and the reaction kettle body is evacuated by a vacuum pump at the same time. After the product in the reaction kettle is heated, under the simultaneous action of vacuum, the moisture of the product begins to evaporate and is gradually pumped away with the vacuum pump, thereby achieving the purpose of drying the product. [0003] The kettle body of the existing vacuum drying kettle is in a fi...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the limitations of the structure of the existing vacuum drying kettle, stirring blades are used as the mechanism that needs to dry the product to be heated evenly. In actual work, it cannot effectively ensure that the product is heated evenly, and after a long time, it is easy to stick to the stirring blade and the product due to continuous adhesion. On the stirring shaft, the vibration of the whole equipment is unreliable, and the volume of the kettle body becomes smaller. The invention provides that under the action of the relevant mechanism, the kettle body can be continuously driven to rotate during work, thereby ensuring the uniformity of the product in the kettle body. It is a kind of vacuum drying kettle for fine chemical production that is heated, and because there are no relevant parts in the kettle body, it prevents vibration due to product attachment when the overall equipment is working, and ensures the effective volume of the kettle body.
