Description

A high-efficiency percolation extraction device

technical field

The utility model relates to a high-efficiency percolation extraction device, which belongs to the technical field of percolation extraction equipment.

Background technique

Zushima injection is a sterile aqueous solution made from traditional Chinese medicine Zushima after extraction and purification, and its active ingredient is daphnetin. At present, the extraction method of Zushima injection is to add the medicinal materials into the percolation extraction extraction tank, add a certain concentration of ethanol solution for percolation extraction, and the leachate flows into the liquid storage tank, and then transfers to the concentrator for heating and decompression Concentration, the process is longer, requires more man-hours, and requires more equipment.

Patent CN 203469533 U A continuous reflux extraction device for traditional Chinese medicine relates to a device that can realize reflux extraction, but the device still needs to be extracted in the extraction tank before the discharge valve of the extraction tank can be opened, and the extraction liquid and The drug enters the follow-up equipment for concentration. Complete loop extraction cannot be achieved.

Utility model content

The utility model overcomes the deficiencies of the prior art, and the technical problem to be solved is to provide a high-efficiency percolation extraction device capable of realizing real-time circulation extraction.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a high-efficiency percolation extraction device, including six equipments: a percolation extraction tank, a double filter, a heating chamber, an evaporation chamber, a condenser, and a cooler;

The outlet of the percolation extraction tank is connected with the inlet of the duplex filter through the pipeline; the liquid outlet of the duplex filter is connected with the liquid inlet of the heating chamber through the pipeline; the heating chamber is connected with the evaporation chamber through the pipeline, and the evaporation chamber The pipeline communicates with the condenser, and the condenser communicates with the cooler through the pipeline; the cooler communicates with the solvent inlet of the percolation extraction tank through the pipeline. The positional relationship of the six devices is: the horizontal position of the center of gravity of the percolation extraction tank, the condenser and the cooler rises in turn, the horizontal position of the center of gravity of the evaporation chamber is higher than that of the heating chamber, and the horizontal position of the center of gravity of the cooler is higher than that of the evaporation chamber.

A main feature of the utility model is that, except that the flow control valve is provided at the outlet end of the cooler or the solvent inlet end of the percolation extraction tank, the connecting pipes between two of the six devices and the ports of the connecting pipes No other control valves are set.

The above structure makes it possible that when the utility model is used for percolation extraction of medicinal materials, the six devices are always connected during the extraction process, and the solvent, the solvent carrying the active ingredients of the drug or the solvent vapor are reciprocating in the percolation extraction device all the time . Relying on the vapor pressure formed by the evaporation chamber, the negative pressure formed by the cooler, and the hydraulic pressure of the percolation extraction tank, etc., the integration of percolation extraction and concentration processes is truly realized, which greatly saves extraction time and improves production efficiency.

This structure can ensure that no additional solvent is needed during a percolation process.

In addition, a pressure detector may also be provided at the steam outlet of the evaporation chamber, and the cooler may also be provided with a solvent sub-addition port, and the sub-solvent addition port is used for replenishing solvent when the pressure detector detects that the pressure is insufficient. Alternatively, a pressure detector is provided at the vapor outlet of the evaporation chamber, and the percolation extraction tank is also provided with a solvent sub-addition port, and the solvent sub-addition port is used to supplement the solvent when the pressure detector detects that the pressure is insufficient.

The above two forms of design are due to the fact that after each percolation extraction is completed, part of the solvent will be taken away by opening the tank to remove the drug residue, or there will be other forms of loss. When the next percolation extraction is performed, the percolation extraction device will form a cycle Finally, you can observe the pressure value of the pressure detector, which is less than the required pressure standard value at the beginning, and you need to open the secondary solvent addition port to replenish the solvent until the pressure value of the pressure detector reaches the required pressure standard value.

When the utility model is used for percolation extraction, after the internal circulation is stabilized, the percolation liquid is directly put into the concentrator at a constant speed, percolation is concentrated under reduced pressure, and the water vapor generated by evaporation is condensed into water and added to the percolation extractor In the process, it realizes percolation extraction while concentrating, and the concentrated recovered water enters the percolation extractor. The liquid storage tank for leachate storage is saved, the process of putting the leachate from the percolation extractor into the liquid storage tank, and then putting the liquid storage tank into the concentrator becomes the process of directly putting the leachate into the concentrator , saving a process and shortening the working time by 4 hours.
