Extraction separation device and system thereof and extraction separation method

Abstract

The invention provides an extraction separation device and a system thereof and an extraction separation method and belongs to the field of extraction separation. The extraction separation device comprises a kettle seal, a kettle and a dreg discharge cabin from top to bottom in sequence, wherein the kettle seal is connected with the upper end of the kettle through a flange; the dreg discharge cabin is connected with the lower end of the kettle through flanges; the kettle comprises a shell and a filtering cylinder which is arranged in the inner cavity of the shell; the shell is of a double-layer cylindrical structure and comprises an inner-layer shell and an outer-layer shell which are coaxially arranged; the diameter of the inner-layer shell is smaller than the inner diameter of the outer-layer shell; an upper turnup side and a lower turnup side are respectively arranged at the upper end and the lower end of the shell; the inner-layer shell, the outer-layer shell, the upper turnup sideand the lower turnup side encircle to form a sealed interlayer cavity; the diameter of the filtering cylinder is smaller than the inner diameter of the inner-layer shell; the filtering cylinder comprises a feeding hole, a main body and a filtering cylinder turnup side which are connected integrally; the main body is of an upright cylindrical structure and comprises a cylindrical filtering net layer and a reinforcing layer which is fixedly connected with the filtering net layer.

Description

technical field [0001] The invention belongs to the field of extracting and separating effective medicinal components, resins and rubbers from plant components, and specifically relates to an extraction and separation device, its system and an extraction and separation method, which are suitable for extracting and separating organic chemical substances from plants by using solvents. Background technique [0002] Traditional devices and methods for extraction, separation and purification of liquid-solid systems (such as traditional Chinese medicine) have many shortcomings. For example, 1) The traditional extraction device adopts a horizontal mesh design for filtration, which results in the residue of the extract clogging the mesh, resulting in poor flow of the extract and low efficiency; 2) the traditional device adopts the same outlet design process for liquid discharge and slag discharge, and the liquid is discharged first After the slag is discharged, the result is that th...

For example, 1) The traditional extraction device adopts a horizontal mesh design for filtration, which results in the residue of the extract clogging the mesh, resulting in poor flow of the extract and low efficiency; 2) the traditional device adopts the same outlet design process for liquid discharge and slag discharge, and the liquid is discharged first After the slag is discharged, the result is that the liquid will block the mesh with the residue during the liquid discharge process and reduce the efficiency; 3) In order to improve the sealing effect, the discharge port of the traditional device is often designed with a narrow opening, which is inconvenient bec
