Problems solved by technology

[0003] At present, the existing traditional Chinese medicine extraction device for pharmacy teaching uses water or an organic solvent as a medium to perform decoction extraction and heat reflux extraction of Chinese medicinal materials in a stirring state. In this way, the extraction time is too long during the teaching process. The efficiency is low. To improve the extraction efficiency, it is necessary to increase the total amount and volume of the equipment. It is not suitable for classroom teaching to practice and use.

Embodiment 1

[0031] like figure 1 Shown is a traditional Chinese medicine extraction device for pharmacy teaching, comprising a stirring box 1 and a microwave extraction box 2;

[0032] The stirring box 1 is provided with a first one-way filter assembly 4 that is sealed and slidingly connected to the inside of the stirring box 1. The stirring box 1 below the first one-way filter assembly 4 is provided with an extraction liquid inlet 9 and a traditional Chinese medicine. The inlet 10 is provided with a stirring shaft 5 in the stirring box 1, and one end of the stirring shaft 5 extends to the top of the stirring box 1 and is fixedly connected with the rotating shaft of the forward and reverse stirring motor 7 provided on the top of the stirring box 1 , the other end of the stirring shaft 5 extends to the lower part of the stirring box 1 and is fixedly connected to the stirring blade 6 arranged in the lower part of the stirring box 1; Turn or reverse, in the case of forward or reverse, it ca...

Embodiment 2

[0039]On the basis of Example 1, in order to ensure that the first one-way filter assembly 4 will not collide with the stirring liquid in the process of descending, a blocking plate 25 is provided in the stirring box 1, The baffle plate 25 is provided with a plurality of stirring liquid through holes 11, the baffle plate 25 is located between the extraction liquid inlet 9 and the traditional Chinese medicine adding port 10, and the stirring blade 6 is arranged under the baffle plate 25, and the through holes 11 pass through the baffle plate 25. The stirring shaft 5 of the blocking plate 25 is fixedly connected. The blocking plate 25 can ensure the blocking of the descending first one-way filter assembly. When the first one-way filter assembly is blocked, the forward and reverse motor drives the stirring shaft to turn over, and drives the first one-way filter assembly. The one-way filter assembly goes up to lift the filtered extraction liquid; the stirring blade through hole 11...

Embodiment 3

[0041] On the basis of Example 1, in order to ensure that the extracted liquid and slag can be effectively separated after microwave extraction, a second one-way filter assembly 14 is slidably and sealed in the microwave extraction box 2, The second one-way filter assembly 14 is threadedly connected with a drive screw 15 disposed in the microwave extraction box 2 . The top of the drive screw 15 passes through the microwave extraction box 2 and the top of the microwave extraction box 2 is provided with a drive The rotating shaft of the motor 13 is fixedly connected; the lower part of the drive screw 15 passes through the microwave extraction plate 16 and extends to the bottom of the microwave extraction box 2 and is movably connected to the bottom plate of the microwave extraction box 2;

[0042] The microwave extraction plate 16 is provided with an extraction liquid through hole 17 , and the lower part of the microwave extraction plate 16 is connected to the bottom of the micro...

Abstract

The invention relates to a traditional Chinese medicine extraction device for pharmacy teaching, which comprises a stirring box and a microwave extraction box; The stirring motor is connected, and the stirring shaft is fixedly connected with the stirring blade; the first one-way filter assembly is threadedly connected with the stirring shaft; a microwave extraction plate is arranged in the microwave extraction box, and a plurality of magnetrons are arranged on the microwave extraction plate, and the magnetron The tube is connected with the microwave generator fixed outside the microwave extraction box through a waveguide; the top of the stirring box is connected with the microwave extraction box through the extraction pipeline, and the end of the extraction pipeline connected with the microwave extraction box is provided with a single The directional valve speeds up the extraction efficiency of traditional Chinese medicine, and it can be better demonstrated during teaching, and at the same time, it does not affect the extraction efficiency during teaching.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine extraction, in particular to a traditional Chinese medicine extraction device for pharmacy teaching. Background technique [0002] The chemical composition of traditional Chinese medicine contains very complex components, including a variety of active ingredients, ineffective ingredients, and toxic ingredients. Extracting its active ingredients and further separating and purifying them to obtain effective monomers is an important content in the field of traditional Chinese medicine research. Extraction of traditional Chinese medicine is to use some techniques to extract the active ingredients to the maximum extent, so as to improve the inherent quality of traditional Chinese medicine preparations and the clinical treatment effect, so that the effect of traditional Chinese medicine can be maximized. [0003] At present, the existing traditional Chinese medicine extraction devi...
