The invention relates to the technical field of drug synthesis, and particularly discloses a drug intermediate reaction still for drug production. Aiming at the problem that as for existing manual feeding, the feeding amount cannot be controlled, now the following scheme is proposed, the drug intermediate reaction still comprises a tank body, a driving device is arranged at the top of the tank body, a rotary shaft is arranged at the output end of the driving device and provided with three stirring blades, a water discharging pipe is arranged at the bottom of the side wall of the tank body, a connecting pipe is arranged on the side, away from the water discharging pipe, of the top of the side wall of the tank body, an agentia box is connected to the other end of the connecting pipe and comprises a shell, a push rod is arranged on the outer top wall of the shell, a limiting rod and a threaded rod are arranged on the two sides of the push rod correspondingly, the push rod penetrates through the shell and then is fixedly provided with a mounting plate, a connecting plate is arranged at the bottom of the mounting plate, and a piston plate is arranged below the connecting plate. By controlling the feeding amount, the resource is saved, the product quality is also ensured, and raw material waste is lowered.
Description
technical field [0001] The invention relates to the technical field of medicine synthesis, in particular to a medicine intermediate reaction kettle for medicine production. Background technique [0002] Generally, the reaction kettle is used in the production process of pharmaceutical intermediates. At present, the scattered raw materials are mainly put into the reaction kettle through the feeding port at the upper end of the reaction kettle manually, which cannot control the feeding amount well and greatly reduces the finished product. The quality of the reaction kettle is high, and there are likely to be residual substances on the inner wall of the reaction kettle after the reaction, which will cause pollution. Therefore, we have designed a drug intermediate reaction kettle for pharmaceutical production to solve the above problems. Contents of the invention [0003] The invention proposes a medicine intermediate reaction kettle for medicine production, which solves the p...
