Description
This utility model relates to the equipment of a kind of extraction and concentrated traditional Chinese medicine.
In the present pharmaceutical industry of China, extract, concentrating employed equipment is the independent separately work of also separately carrying out, extracting employed equipment is extraction pot, concentrating employed equipment is concentrator, owing to have many Chinese medicines and bio-pharmaceuticals to extract at 60 ℃ of left and right sides low temperature, so that active ingredient exempts from destruction, and the extraction of existing extraction pot is to carry out at 100 ℃-120 ℃, can't satisfy the instructions for use of extract at low temperature in the production, extraction pot is when extracting work on the other hand, whenever feed intake once, need to change solvent two to three times, always need six to eight hours ability to extract and finish, consumption of energy is very big, and energy expenditure is also very big when concentration extraction produced a large amount of extracting solution.
The purpose of this utility model provides a kind ofly can carry out extract at low temperature easily and can reduce extraction and the Chinese medicine extraction concentrator of the energy expenditure when concentrated.
To achieve these goals, technical solution of the present utility model is such: design a kind of Chinese medicine extraction concentrator, it mainly comprises extraction pot and the concentrator of mainly being made up of heater, vaporizer, between the bottom of the bottom of extraction pot and concentrator, be provided with the medicinal liquid connection tube, the medicinal liquid connection tube is provided with by-pass valve control, the position of extraction pot is than concentrator height, and the medicinal liquid in the extraction pot can do that the control through by-pass valve control flows to concentrator under the power at gravity; Be provided with the steam connection tube between the top of extraction pot and the top of vaporizer, the steam connection tube is provided with the extraction valve; The top of extraction pot does not also have reflux condenser, tedge is communicated with the top of extraction pot and the inlet of reflux condenser, the outlet of reflux condenser and vacuum system are communicated with, reflux condenser comprises condensation tube and runner pipe, condensation tube is closed cavity and is provided with filling pipe end and the following mouth of a river, the two ends of runner pipe are the entrance and exit of reflux condenser, runner pipe exports from entering the mouth to through one or many up and down reciprocatingly, the major part of runner pipe is arranged on the condensation tube inner chamber, and space and condensation tube inner chamber are separated mutually in the pipe of runner pipe; Be connected to return duct between corner and the extraction pot down in each of the runner pipe of reflux condenser, return duct is provided with compensator, compensator leads to extraction pot through a reflux inlet, and compensator is that a cross section is more much bigger and have a container of certain altitude than return duct.
In above-mentioned technical solution, when by-pass valve control and extraction valve are closed, because the top of extraction pot also is connected with reflux condenser, the outlet of reflux condenser also connects vacuum system, evacuation when extraction pot extracts, extract temperature by control vacuum with regard to may command, realize extract at low temperature, since the runner pipe of reflux condenser be in condensation tube, up and down reciprocatingly be provided with and condensation tube in runner pipe around the cooling liquid that flowing, flowing through the steam of reflux condenser and medicine part can be in condensation on the wall of runner pipe and flow to time corner down, be back to extraction pot by return duct and compensator, thereby realize independent extract at low temperature, when by-pass valve control and extraction valve are all opened, the extracting solution of extraction pot is pressed certain velocity flow to concentrator by the medicinal liquid connection tube, the steam that produces when concentrator concentrates flows to extraction pot by the steam connection tube, promptly carry out a circulation, circulation simultaneously evacuation makes the vacuum that keeps certain in the cyclic space realize extract at low temperature and concentrates and drive steam and is back to extraction pot circulation is carried out smoothly, because circulation is being carried out extracting and concentrating, extraction time is shortened greatly, the total amount that produces extracting solution is also than original lack many, significantly reduce thereby can make extraction and concentrate the energy that is consumed, but therefore the utlity model has extract at low temperature and concentrated, and the effect that can save energy.
