Description
Technical Field
The invention relates to a spiral separator for separating fat-soluble and water-soluble mixed liquid, belonging to the technical field of mixed liquid separation.
Background
Extraction refers to a process in which a compound is transferred from one solvent to another by utilizing the difference in solubility or partition coefficient of the compound in two solvents that are not (or slightly) miscible with each other, and thus, most of the compound is extracted over a number of repetitions. Extraction is a common technical means in the fields of chemistry, chemical engineering and biopharmaceuticals, and is widely applied.
The extract obtained after extraction is generally layered by a standing mode and then separated and obtained, but the method is long in time consumption, needs large-volume tank storage, cannot observe the separation condition in real time, and is not suitable for industrial, large-scale and industrialized production.

FIG. 1 is a schematic diagram of a spiral separator for separating a fat-soluble and water-soluble mixed solution according to the present invention.
Detailed Description
The first embodiment is as follows: the present embodiment, which is a spiral separator for separating a fat-soluble and water-soluble mixed solution, is described below with reference to fig. 1, and includes a drainage separation spiral pipe, a conduit 2 and a collection tank 3,
the drainage separation spiral pipe is a spiral pipeline with gradually smaller spiral diameter and gradually smaller spiral pitch from top to bottom, the drainage separation spiral pipe comprises a guide section 1-1 at the head end and a spiral section 1-2 connected with the guide section, and the tail end of the spiral section 1-2 corresponds to the inlet of the guide pipe 2; the spiral section 1-2 is positioned inside the collecting barrel 3;
the outer surface of the drainage separation spiral tube is coated with a lipoid/cellulose acetate composite adsorption film.
In the process of separating mixed liquid, firstly, the mixed liquid to be separated is guided to the outer wall surface of the spiral section 1-2 by using the guide section 1-1, so that the mixed liquid is completely attached to the spiral section 1-2 to flow downwards, and in order to ensure the separation effect, the head end of the spiral section 1-2 adopts a relatively large screw pitch and a relatively large diameter size, and the mixed liquid is ensured to completely follow the pipe wall of the spiral section 1-2 at a relatively slow flow speed, so that the loss of the mixed liquid is reduced. As the pitch and diameter of the screw section 1-2 decrease, the flow rate increases and the water-soluble substance floats out of the screw section 1-2 into the collection tub 3 due to centrifugal force. The separated fat-soluble substance flows into the catheter 2 and is guided out and collected.
The main body of the drainage separation spiral pipe adopts a deformable pipe body, or the diameter-height ratio, the number of spiral cycles (layers), the reduction amplitude of the spiral diameter, the diameter of the pipe body and the like of the spiral section of the drainage separation spiral pipe are adjusted according to the property of the separated extraction liquid.
Compressed air can also be used to increase the initial flow rate of the extract to better achieve separation.
The device according to the embodiment is suitable for the fields of medicine, biological extraction and chemical product manufacturing.
