The application discloses a kind of gas-liquid two-
phase mixing type reaction kettle for pharmaceutical intermediates production and drive control method, it is related to pharmaceutical intermediates production equipment technical field.In the application: the bottom of reaction kettle is equipped with gas inlet end, inner cavity is configured with driving shaft and stirring
paddle, top cover is configured with
gas concentration sensor and multiple inverted cone, and inner cavity is provided with floating mixing disc.The
piston ring is arranged on the side of floating mixing disc, the main shaft sleeve and the flow guide
pipe are arranged on the top of floating mixing disc, the jet
nozzle is arranged on the top end of flow guide
pipe, and the liquid outlet of jet
nozzle is opposite to the lowest point of inverted cone.The floating mixing disc is provided with flow guide slope and flow guide channel, the flow blocking component is elastically installed at the flow guide channel, a liquid level meter is further arranged, and the reaction kettle is provided with a hydraulic
system for driving the floating mixing disc to rise and fall.The application realizes efficient mixing of gas-liquid two-phase by dynamically controlling the rising and falling of floating mixing disc, improves reaction efficiency and product quality, and is suitable for gas-liquid two-
phase reaction production of pharmaceutical intermediates.
