Abstract

The invention relates to a continuous countercurrent extracting tank for extracting traditional Chinese medicines, comprising a tank body, a material pushing spiral conveyor, a driver, a medicinal material inlet, an extracting solution overflowing outlet, a solvent inlet, a decoction dreg slot, a spiral dreg discharging machine and the like, wherein the driver drives the material pushing spiral conveyor to rotate towards one direction and push medicines to move from top to bottom along the spiral conveyor, a solvent flows opposite to the medicinal materials from the bottom, decoction dregs are airtightly discharged out of a chamber by the spiral dreg discharging machine, the outer edge of the material pushing spiral conveyor is provided with a flexible non-return seal, and the volume of the tank body is partitioned into a continuous and long spiral strip-shaped space by the material pushing spiral conveyor, thereby creating conditions for the better uniform fluidity, diffusion and osmosis of an extracting solution and the medicines. The technology in the invention can be used for reforming an out-dated multifunctional extracting tank, the material pushing spiral conveyor and corresponding components are additionally arranged in the inane multifunctional extracting tank so that the multifunctional extracting tank with low yield and high energy consumption is reformed into a continuous countercurrent extracting tank with doubly increased yield and greatly reduced energy consumption, thereby playing a better role for the production of the traditional Chinese medicines after the reformation.

Description

technical field [0001] The patent of the invention relates to a continuous countercurrent extraction tank, which belongs to the technical field of chemical and pharmaceutical extraction, and is used for continuous countercurrent extraction of natural animals and plants with water or organic solvents. Background technique [0002] Patent No.: 200910046851. The development purpose of the 9 continuous countercurrent baffle tube extraction machine is to eliminate and replace the existing backward multifunctional extraction tank. Considering the multifunctional extraction tank made of stainless steel, it has been widely used in various Chinese medicine production plants in my country, and there are thousands of them. The new high-efficiency and energy-saving continuous countercurrent baffle tube extraction machine replaces the multi-functional extraction tank. Although it is very beneficial to improve the production of traditional Chinese medicine in my country, it will also cost...
