The working principle and the beneficial effects of the scheme are as follows: when the distillation still of this scheme of adoption distills the medicine, pour into the cauldron internal with medicine mixed liquid from the feed inlet, then open heating element and heat the cauldron body, the heating temperature is greater than the lower person of mixed liquid mid boiling point, is less than the higher person of mixed liquid mid boiling point. The vapor generated after the vaporization of the liquid with lower boiling point flows out from the gas collecting hole on the clapboard, then enters the condensing pipe to be liquefied under the action of the condenser, and flows into the collecting container, thus completing the distillation process. The wind wheel blades are fixedly connected to the second rotating shaft, the second rotating shaft and the first rotating shaft rotate through the chain, and the first rotating shaft is fixedly connected with the stirring blades, so that the stirring blades can also rotate along with the wind wheel blades when the wind wheel blades rotate, mixed liquid is stirred, the mixed liquid is fully reacted, the utilization rate is improved, the production cost is reduced, and meanwhile, the liquefaction speed of the liquid can be accelerated through stirring, so that the production efficiency is improved; in addition, the stirring blade in the scheme is not required to be driven by an external motor, the structure is simple, the cost is low, and the energy consumption is reduced.
Furthermore, the clapboard is a conical plate, and the gas collecting hole is positioned at the conical tip of the clapboard. Through the arrangement, the steam can be quickly guided to the gas collecting hole.
Furthermore, a sleeve for wrapping the chain is connected at the through hole of the partition plate. The purpose of which is to avoid a large amount of steam flowing out of the through-hole.
Further, the heating assembly is an electric heating jacket. The electric heating sleeve has simple structure and uniform heating.
Further, the kettle body is also communicated with an air duct, and the air duct is connected with a vacuum pump. Its purpose can adjust the internal atmospheric pressure of cauldron through the vacuum pump, because the boiling point of liquid changes along with atmospheric pressure change, the atmospheric pressure is low, and the boiling point is also low, consequently adopts the setting of this scheme to reduce the internal pressure of cauldron and reduce the boiling point of liquid, reduce heating temperature, improve production efficiency.
Further, a barometer is arranged on the air duct. The purpose is to facilitate the observation of the specific numerical value of the pressure intensity in the kettle body.
