Multi-linkage reciprocating extrusion type trace extraction-separation integrated device and using method

Abstract

The invention relates to an extraction and separation device, in particular to a multi-linkage reciprocating extrusion type trace extraction-separation integrated device and a using method. The device comprises a pipe frame assembly, a lifting assembly rotating shaft and a support, the pipe frame assembly comprises side guide rods located at the two sides and a pipe frame connected between the two side guide rods, an extraction pipe is arranged on the pipe frame, the extraction pipe is a place for extraction and separation, the lifting assembly comprises a sliding block connected between the two side guide rods, a stirring and extruding column is connected to the sliding block, the sliding block can slide up and down along the side guide rods so as to drive the stirring and extruding column to enter and exit the extraction pipe, and the outer sides of the side guide rods are connected to the support through rotating shafts. The pipe frame assembly and the lifting assembly can synchronously swing through the rotating shaft, the stirring and extruding column enters and exits the extraction pipe to achieve extraction in the vertical state of the extraction pipe, and the stirring and extruding column enters the extraction pipe to achieve separation after extraction in the inclined state of the extraction pipe.

Description

technical field [0001] The invention relates to an extraction and separation device, in particular to a multi-reciprocating extrusion type micro extraction-separation integrated device and a use method. Background technique [0002] Liquid-liquid extraction is a common pretreatment method, which is a process of separating and extracting components in a liquid mixture with a solvent. A selected solvent that is immiscible (or slightly miscible) is added to the liquid mixture, and the different solubility of its components in the solvent is used to achieve the purpose of separation or extraction. At present, the most common liquid-liquid extraction process in the laboratory mainly uses a separatory funnel, through repeated manual inversion or shaking, to fully mix the liquid mixture with the extraction solvent, so as to promote the components to be extracted in the extraction solvent and liquid mixture reach dissolution equilibrium. Although this method has simple equipment a...

Problems solved by technology

The extraction principle is different from that of the extrusion extraction in the present invention, and the extraction operation cannot be performed on a small amount of samples. At the same time, the above three sets of devices need to be driven by electricity, and the structure is relatively complicated.
