Embodiment Construction

[0029] Please refer to Figure 1 to Figure 3 , the present invention is mainly composed of mechanical transmission part, tower body, sieve plate, liquid phase disperser and auxiliary facilities. in:

[0030] The mechanical transmission part includes:

[0031] The eccentric wheel 1 connected with the motor, one end of the main shaft 3 is connected with the eccentric wheel 1 by the connecting rod 2, and the other end is connected to the inner tower circular sieve plate 8 and a main and secondary shaft connecting rod 13 through the slider 4. , The secondary shaft connecting rod 13 is connected with the secondary shaft 7 connecting the outer tower annular sieve plate 9 . When the motor rotates, the circular sieve plate 8 of the inner tower and the annular sieve plate 9 of the outer tower vibrate accordingly.

[0032] The tower part includes:

[0033] The outer tower body 5 and the concentric inner tower body 6 inside it; the top of the inner tower body is open, so that the mes...

Abstract

A vibrating sieve-platte tower for three-phase (liquid-liquid-liquid) continuous extractions is suitable for a system containing solid and liquid easy to emulsify is composed of mechanical transmission unit, tower body, sieve plate, liquid-phase disperser and auxiliary unit. Its advantages are simple structure, flexible operation, easy regulation and low cost.

Description

technical field [0001] The invention belongs to liquid-liquid-liquid three-phase continuous extraction equipment, and relates to the extraction process between three liquid phases with different densities (respectively called heavy phase, intermediate phase and light phase according to different densities). The target product was separated in the system. The invention is particularly suitable for separating and purifying high value-added biochemical products, such as various antibiotics, proteins, vaccines, enzymes and hormones, from biological product fermentation liquid by a three-phase one-step method. Background technique [0002] Solvent extraction has been used as a traditional separation and purification method for hundreds of years. It is widely used in petroleum, chemical, pharmaceutical, metallurgy, environmental protection and biological engineering and other fields. The traditional solvent extraction process and equipment are mainly suitable for liquid-liquid t...
