Embodiment 1

[0028] Such as figure 1 Shown is a drum mixing extraction device, which includes a fixed outer cylinder 2 and an inner cylinder 1; the inner cylinder 1 can rotate along a rotating shaft 3. When the equipment is running, the outer cylinder 2 is fixed, the inner cylinder 1 rotates along the direction of the rotating shaft 3, and the two move relatively. The device is provided with some small holes on the inner side of the outer cylinder and the outer side of the inner cylinder along the radial direction, and the small holes 4 on the inner cylinder wall and the small holes 5 on the outer cylinder wall are connected when they are opposite. The small holes 4 of the inner cylinder wall and the small holes 5 of the outer cylinder wall have the same size. The upper part of the outer cylinder is the heavy phase inlet 6 and the light phase outlet 9 , and the lower part is the light phase inlet 7 and the heavy phase outlet 8 . The device is made of fiberglass material.

Embodiment 2

[0030] A drum mixing extraction device, the device includes a base, a fixed outer cylinder 2 and an inner cylinder 1; the inner cylinder 1 can rotate along a rotating shaft 3, and the outer cylinder 2 and the rotating shaft 3 are fixed on the base. When the equipment is running, the outer cylinder 2 is fixed, the inner cylinder 1 rotates along the direction of the rotating shaft 3, and the two move relatively. A motor driving the rotating shaft 3 is installed in the base. The device is provided with some small holes on the inner side of the outer cylinder and the outer side of the inner cylinder along the radial direction, and the small holes 4 on the inner cylinder wall and the small holes 5 on the outer cylinder wall are connected when they are opposite. The small holes 4 of the inner cylinder wall and the small holes 5 of the outer cylinder wall have the same size. The upper part of the outer cylinder is the heavy phase inlet 6 and the light phase outlet 9 , and the lower ...

Embodiment 3

[0032] An extraction method of a drum mixing extraction device, firstly start the motor in the base to drive the rotating shaft 3 to rotate, and the inner cylinder 1 to rotate; the heavy phase enters from the heavy phase inlet 6, and the light phase enters from the light phase inlet 7; when the inner cylinder wall When the small hole 4 and the small hole 5 of the outer cylinder wall are facing each other, the heavy phase will drop and the light phase will rise, and both will be sheared and broken; when the holes are not opposite, the light and heavy phase cannot flow through the hole; The light phase droplets and the heavy phase droplets are completely mixed for extraction, and finally the light phase is collected from the light phase outlet 9, and the heavy phase is collected from the heavy phase outlet 8.

Abstract

The invention relates to a mixing extraction device with a rotating barrel and an extraction method. The mixing extraction device comprises a fixed outer barrel and an inner barrel, the inner barrel can rotate along a rotating shaft, and slits between the outer barrel and the inner barrel are very small. When equipment runs, the outer barrel is fixed, the inner barrel rotates in the direction of the rotating shaft, and the inner barrel and the outer barrel can move relative to each other. When extraction is carried out, first a motor in a base is started to drive the rotating shaft to rotate, and the inner barrel rotates; heavy phase materials enter from a heavy phase inlet, and light phase materials enter from a light phase inlet; when small holes of an inner barrel wall are opposite to small holes of an outer barrel wall, the heavy phase materials descend, the light phase materials rise, and the heavy phase materials and the light phase materials are sheared and broken; when the small holes of the inner barrel wall are not opposite to the small holes of the outer barrel wall, the heavy phase materials and the light phase materials cannot flow through the holes; and after a period of time, the sheared light phase liquid drops and the sheared heavy phase liquid drops are totally mixed, and extraction is carried out. The extraction device is particularly suitable for an easily-emulsified system with phase ratio of a far cry, and uniform mixing can be achieved in a short time on the condition that two phase interfaces are clear so to as to finish extraction.

Description

technical field [0001] The invention relates to a liquid-liquid two-phase solvent extraction device and method in the fields of medicine, metallurgy or biochemistry, in particular to a drum mixing extraction device and extraction method, especially to a short-time extraction method for a disparate and easy-to-emulsify system Extraction device and method. Background technique [0002] Solvent extraction technology is a mass transfer separation process in which a liquid extractant is used to treat immiscible two-component or multi-component solutions to achieve component separation. It is mainly used for the separation and purification of substances. It has the characteristics of simple equipment and easy operation. It can be used to separate and purify a large number of substances, and is more suitable for the separation and enrichment of trace or trace substances. It is widely used in analytical chemistry and atomic energy. , metallurgy, electronics, environmental protectio...
