Description

Extraction kettle convenient to pressurize Technical Field The utility model relates to the technical field of extraction equipment, in particular to an extraction kettle convenient to pressurize. Background In many fields such as chemical industry, pharmacy and food, an extraction kettle is a common device for extracting active ingredients from solid materials, pharmacological active substances can be extracted from natural biological materials by adding different solvents, reactants and reaction conditions, and the extraction kettle can also be used for operations such as solvent crystallization, melt cooling, gas phase quenching and the like in the process of drug crystallization, so that drug molecules form a more stable crystal structure, and the purity and stability of the drug are improved. The pressurization structure of traditional extraction kettle needs longer time to reach the settlement pressure in the pressurization process, and pressure homogeneity is relatively poor, prolongs the extraction cycle, still probably causes the material to draw incompletely, reduces production efficiency and raw materials utilization ratio. Disclosure of utility model The utility model aims to provide an extraction kettle convenient to pressurize, which solves the problems that in the background technology, the set pressure is required to be reached for a long time in the pressurizing process, the pressure uniformity is poor, and the extraction period is prolonged. The extraction kettle comprises a kettle body, wherein the kettle body is of a cylindrical extraction kettle structure, a jacket is sleeved outside the kettle body, the kettle body is penetrated by a stirring rod, the stirring rod is in butt joint with the output end of the stirrer, and the kettle body is a main body of the extraction kettle; The bottom end of the kettle body is provided with a discharging pipe, two sides of the kettle body are symmetrically provided with 2 openings, a steam inlet is fixed in the opening of the kettle body, a limiting bracket is fixedly arranged outside the jacket, and the bottom end of the jacket is fixedly provided with supporting legs; The kettle is characterized in that a water baffle is arranged on the inner wall surface of the kettle body, a gap is reserved between the water baffle and blades of the stirring rod, a pipeline for a material inlet is welded at the upper end of the kettle body, an observation port is formed in the upper end of the kettle body, a circulating water pipe is arranged at the upper end of the kettle body, the kettle body is penetrated by a thermometer, and a detection end of the thermometer is arranged in the kettle body.
