Low rotating speed self-priming extraction equipment

Abstract

The invention relates to a low rotating speed self-priming extraction equipment, characterized in that: a hollow rotating shaft and a liquid phase diffuser fixed on the hollow rotating shaft are arranged in an extraction tank of the extraction equipment, wherein, the shaft wall of the hollow rotating shaft is provided with a feed inlet, the rotating shaft is connected with a motor, the liquid phase diffuser comprises two or more single channel simple liquid phase diffusers in series, each simple liquid phase diffuser is provided with a feed inlet, a hollow rotating shaft, and a hollow rotary drum which are communicated with each other, but each simple diffuser are not communicated through the hollow rotating shaft, and a channel exit of the last N-1 level simple diffuser is provided with a downward-facing outer cover. The extraction equipment is suitable for a large-phase ratio easy-emulsification system. According to the invention, by concatenating at least two self-priming phase-dispersed stirrers into a whole and uniformly dispersing a light phase in a heavy phase, the operation can be continuously carried out under the condition of distinct two-phase interface, thus the emulsification phenomenon is avoided, the advantages of small equipment investment, easy operation, low rotating speed of the motor, low power consumption, and small shearing force to solution are achieved. The invention is beneficial to keep the activity of biomacromolecules.
