Problems solved by technology

[0004] The disadvantage of the above-mentioned prior art is that the layered liquid level can only be observed manually through the upper mirror, and it is difficult to determine the correct position of the layered layer
It is difficult to adjust the position of the liquid outlet pipe of the light liquid, either the light liquid cannot be exhausted, or the heavy liquid is also released, resulting in incomplete extraction and separation or a large loss of the light phase

Embodiment 1

[0019] See figure 1 The extraction and extraction dual-purpose integrated machine of this embodiment includes: an extraction tank 1, a stirring shaft 2 arranged on the central axis of the extraction tank 1 and equipped with a paddle 4 at the bottom, and inside the extraction tank 1 And a plurality of stirring rings 3 axially distributed on the stirring shaft 2, a plurality of static rings 5 ​​arranged on the inner wall of the extraction tank 1 and distributed with each stirring ring 3; the extraction tank 1 The top of the extraction tank 1 is provided with a heavy liquid inlet for inputting heavy liquid and a light phase outlet for outputting light phase feed liquid, and the bottom of the extraction tank 1 is provided with a light liquid inlet for inputting light liquid and a heavy phase for outputting heavy phase Outlet; a clarification tank 8 is provided above the extraction tank 1, the light phase outlet of the extraction tank 1 is connected to the bottom of the clarificati...

Embodiment 2

[0025] The working method of the above-mentioned extracting and extracting dual-purpose integrated machine includes:

[0026] Input the heavy liquid into the extraction tank 1 through the heavy liquid inlet on the top of the extraction tank 1, observe the liquid level through the glass sight glass on the top of the extraction tank 1, and stop the feed liquid input when the liquid level reaches the preset height ;

[0027] Slowly start the stirring shaft 2 and start stirring;

[0028] Slowly heat to keep the feed liquid in the extraction tank 1 at a preset temperature (the temperature is determined by the mass transfer temperature of the active ingredient to be extracted or extracted in the corresponding extract or extract, refer to the relevant technical manual or pass selected by multiple trials);

[0029] Evenly enter the light phase into the extraction tank 1 from the liquid distributor at the bottom of the extraction tank 1. During the stirring process, the phases realiz...

Abstract

The invention relates to an extraction and abstraction dual-purpose integrated machine and a working method thereof, and the integrated machine comprises an extraction tank, wherein a heavy liquid inlet and a light phase outlet are arranged at the top of the extraction tank, and a light liquid inlet and a heavy phase outlet are arranged at the bottom of the extraction tank; and a clarification tank is arranged above the extraction tank, and the light phase outlet of the extraction tank is connected with the bottom of the clarification tank, and a light liquid outlet is arranged at the top of the clarification tank. The integrated machine breaks through the traditional process, shortens the extraction section and is made into the tank which is similar to a traditional stirring tank, the heavy phase is fixed in the tank, and the working time can be adjusted at any time according to the concentration monitoring of light phase discharge. When in use, the heavy phase is loaded into the tank, and the flow rate of the light phase can be regulated arbitrarily, thereby enabling the light phase to achieve the maximum saturated concentration and further meeting the actual production needs. The integrated machine adopts the working method of enabling the heavy phase to be fixed and enabling the light phase to be continuous, can enable the interphase mass transfer to be full and thoroughly, is simple to operate and can reduce the using amount of an extraction agent to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of extraction of plant active ingredients, extraction equipment and technology thereof, in particular to an extraction and extraction dual-purpose integrated machine and its working method. Background technique [0002] In the production of raw materials, there are problems with the extraction and extraction of suspensions or slurries. Different equipment is often used to complete the extraction and extraction steps, resulting in a large equipment space and high requirements for the height of the plant, thus increasing the cost. Production investment costs. [0003] In addition, the existing extraction system often pours a certain amount of suspension or slurry into the extraction tank, then sends a certain amount of solvent from the top of the tank, and then heats up and starts stirring to fully mix the material liquid and the solvent. Then stop stirring, after standing still for a period of time, the ligh...
