Embodiment 1

[0033] The organic phase is kerosene, and a color developer is added to the kerosene, the water phase is deionized water, and the ratio of the organic phase to the water phase is 1:10. The light phase feed inlet diameter of this low-speed self-priming extraction device is 5 mm, and is located at the relative position of the cavity shaft, with the oil phase as the dispersed phase, the shaft cavity diameter is 6 mm, the drum cavity diameter is 30 mm, and There are 12 relatively small holes with a diameter of 4mm. To achieve the same dispersion effect, the required speed of single-stage self-priming extraction equipment is 500rpm, and the required speed of low-speed self-priming extraction equipment is 170rpm.

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.
