Continuous countercurrent flow obstruction rod extractor

Abstract

The invention relates to a continuous countercurrent flow obstruction rod extractor, which is composed of a low-temperature steam generator, a flow obstruction extraction pipe, a spiral stock pusher, a tooth-shaped overflow groove, a medicinal material feeding pipe, a waste slag groove, a spiral slag extractor and so on; more than two serially-connected extraction pipes are welded on a supporting plate of the low-temperature steam generator with the flow obstruction pipe in parallel; continuous quantitative solvent and medicinal material are extracted in a circular pipe without any dead angle of liquid / material accumulation according to the continuous counterflow extraction discipline, so as to reduce the feeding ratio between medicinal material and solvent and favorably save heat energy and power consumption for evaporating the solvent; the waste slag of medicinal material is discharged out of an operating room through the spiral slag extractor in a closed manner, so that the production of Chinese traditional medicine meets the requirements of medicine production better; the spiral stock pusher can be pulled out of the extraction pipe for cleaning, and the operation is time-saving and labor-saving; and moreover, as no extraction-groove type cover plate or cover plate flange is arranged in the extractor, the structure is simple and compact, the occupation area of the equipment is reduced and the vertical height is lowered, therefore, fewer materials are used, the processing is easy and the equipment cost is lowered.

Description

technical field [0001] The invention relates to a continuous countercurrent baffle tube extraction machine, which belongs to the technical scope of liquid-solid phase extraction and is suitable for continuous countercurrent extraction of natural animals and plants by using water or organic solvents. Background technique [0002] At present, the most important extraction technology of Chinese medicinal materials in the production process of traditional Chinese medicine still stays in the state of intermittent single-tank extraction, which has low yield and volumetric efficiency of extraction equipment, and high energy consumption, especially in the discharge of waste at the operation site. When the dregs are used, the dregs juice cross-flows and hot steam overflows, which seriously affects the sanitation of the pharmaceutical production environment. Patent No.: 200620048081. 3. The baffle type continuous countercurrent extraction machine is of trough type. There are dead corn...

AI Technical Summary

Problems solved by technology

Although the 6-fold tube type continuous countercurrent extraction machine has overcome the serious defect of dead angle in the trough type continuous countercurrent extraction machine, its structure is still inseparable from the inherent cover plate and flange mode of the trough structure, and its compactness Insufficient, it is still inconvenient to disassemble and wash, and it also increases the material and cost of the equipment
