Description

Technical Field

[0001] This utility model relates to the field of reaction vessels, and in particular to a reaction vessel for the production of active pharmaceutical ingredients. Background Technology

[0002] Currently, Chinese utility model patent CN220496373U discloses a chemical reaction vessel for the production of active pharmaceutical ingredients (APIs). While this reaction vessel is equipped with a stirring assembly to improve the mixing effect of internal materials, other problems exist during use. For example, it lacks uniform heating; when the outside temperature is low and the reaction vessel lacks sufficient insulation, the internal temperature drops rapidly. This low temperature affects the stability and efficiency of the internal reaction, preventing the chemical reaction from proceeding normally. Furthermore, it lacks exhaust gas purification; when the internal pressure is too high, exhaust and pressure reduction are required. However, the exhaust gas contains various harmful substances, which, if inhaled, can affect health. To address these problems, we propose a reaction vessel for the production of APIs.

After the clean water is injected, the heating pipe and water pump are started simultaneously. After the heating pipe is started, it heats the surrounding clean water. After the water pump is started, it draws in the high-temperature water below through the suction pipe. After the high-temperature water is drawn in, it is discharged upward through the drain pipe to mix with the low-temperature water. This provides uniform heating, improves the applicable environment of the reactor, ensures the normal progress of the internal chemical reaction, and has high practicality.

After the exhaust valve is opened, the internal exhaust gas enters the fixed pipe. After the suction fan is activated, it draws the exhaust gas in the fixed pipe into the purification box. After entering the purification box, the exhaust gas passes through the air filter plate, which intercepts particulate matter and harmful substances in the exhaust gas, thus purifying the exhaust gas. It is simple and convenient to operate, protects the health of surrounding personnel, improves the surrounding environment, and facilitates the replacement of the filter plate.
