Accurate temperature control reaction system for bulk drugs

Abstract

The accurate temperature control reaction system comprises a heating oil tank, a first material tank, a second material tank, a reaction kettle, a condenser, an oil bath tank and an oil return tank, a partition plate is fixedly arranged in the reaction kettle, a mechanical transmission chamber is arranged on the upper side of the partition plate, and a reaction cavity is formed in the lower side of the partition plate; fixing plates are fixedly connected to the cavity walls of the two sides of the interior of the reaction cavity, and threaded rods are rotationally connected to the upper surfaces of the fixing plates, in the reaction device, through the arrangement of a motor, an arc-shaped scraping plate, a rotating disc and a scraping ring, stirring can be more sufficient, automatic cleaning can be achieved, two purposes of one structure are achieved, the equipment cost and the labor cost are effectively saved, and the practicability is high. Meanwhile, the reaction can be more sufficient, the reduction of the reaction accuracy and the influence on the reaction quality caused by the adhesion of raw materials on the inner wall are effectively prevented, and the influence on the next reaction caused by reactant residues can be avoided.

Description

technical field [0001] The invention belongs to the technical field of medical and pharmaceutical processing equipment, in particular to a precise temperature control reaction system for raw materials. Background technique [0002] In the production process of medical drugs, it is sometimes necessary to put two or more raw materials into the reaction kettle for reaction and mixing preparation. During the preparation process, it is necessary to precisely control the temperature of the reaction to ensure the progress of the reaction. Most of the existing reaction systems are Precise temperature control is carried out through electric heating. The antipyretic element of the electric heating device is not easy to replace and the maintenance cost is high, and manual temperature control cannot ensure accurate temperature control. At the same time, the mixing structure of the existing reactor is relatively simple, and most of the The mixing is performed by the stirring paddle, whic...
