Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of traditional Chinese medicine processing, in particular to a device for extracting components of traditional Chinese medicine. Background Art
[0002] As a traditional medical method, Chinese medicine has always played an important role in health care and disease treatment. Chinese medicine preparations are an important part of traditional Chinese medicine therapy. Through the extraction, processing, and compatibility of Chinese medicinal materials, they are made into medicines with certain efficacy. The production process of Chinese medicine preparations is very complicated, covering multiple links, and each step is crucial.
[0003] Extraction is one of the core steps in the production of traditional Chinese medicine preparations, which determines whether the main components of the medicine can be fully extracted. Liquid solvent extraction is a common method for extracting traditional Chinese medicine ingredients. The crushed medicinal materials are placed in a suitable solvent (such as water, alcohol, etc.), and the active ingredients in the medicinal materials are dissolved to form a liquid medicine, thereby completing the extraction of the active ingredients of the traditional Chinese medicine.
[0004] At present, when solvent extraction is performed on Chinese medicinal materials, the medicinal materials are usually directly immersed in the solvent in the extraction container, and then left to stand for a period of time to wait for the effective ingredients to dissolve. However, medicinal material fragments tend to float on the liquid surface, resulting in a decrease in the contact area between the medicinal material fragments and the solvent, which in turn leads to low extraction efficiency. In addition, it is inconvenient to take the medicinal material fragments, which brings inconvenience to the actual extraction. Utility Model Content
[0005] In order to solve the technical problems existing in the background technology, the utility model proposes a device for extracting components of traditional Chinese medicine.
[0006] The utility model provides a Chinese medicinal material component extraction device, comprising an extraction tank and a tank cover, wherein the tank cover is arranged at the top opening of the extraction tank and has an adjustable height, a liftable filter cage is installed inside the extraction tank, a motor is installed on the tank cover, an output end of the motor extends downward into the extraction tank and is provided with a pressing plate, a group of grinding teeth are installed at the bottom of the inner cavity of the filter cage and at the lower end surface of the pressing plate, the pressing plate slides and extends into the filter cage to adjust the spacing between the two groups of grinding teeth, and the medicinal material fragments in the filter cage are squeezed and ground.
[0007] As a further optimized solution of the utility model, the multiple grinding teeth on the bottom surface of the inner cavity of the filter cage are distributed in a circular array to form n first concentric rings, and the n first concentric rings are distributed at equal intervals from the inside to the outside, and the multiple grinding teeth on the lower end surface of the pressure plate are distributed in a circular array to form n second concentric rings, and the second concentric rings are staggered with the first concentric rings.
[0008] As a further optimized solution of the utility model, a base is installed at the bottom of the extraction tank, a cylinder for driving the filter cage to rise and fall is installed inside the base, and a lift for driving the tank cover is installed on the base.
[0009] As a further optimized solution of the utility model, the movable end of the cylinder extends upward into the extraction tank and is detachably connected to the bottom of the filter cage.
[0010] As a further optimized solution of the utility model, a sleeve hole matched with the movable end of the cylinder is opened at the bottom of the extraction tank, and the movable end of the cylinder slides through the sleeve hole and is sealed by a sealing member.
[0011] As a further optimized solution of the utility model, a liquid outlet pipe is installed at the bottom of the extraction tank, one end of the liquid outlet pipe is connected to the bottom of the inner cavity of the extraction tank, and the other end of the liquid outlet pipe is inclined downward and is installed with a valve.
[0012] The Chinese medicinal material component extraction device proposed in the utility model has the following beneficial effects:
[0013] (i) When in use, the Chinese medicinal material fragments are placed in the filter cage, and then the filter cage is installed on the movable end of the cylinder extending upward. After the filter cage is stably installed, the tank cover is driven downward by the elevator, so that the pressure plate extends downward and slides into the filter cage to seal the opening of the filter cage. The filter cage is then driven downward by the cylinder, and the elevator drives the tank cover to move downward synchronously. The filter cage moves to the bottom of the inner cavity of the extraction tank, so that the filter cage and the medicinal materials therein are immersed in the solvent in the extraction tank, and the tank cover is pressed on the top opening of the extraction tank, which can prevent the medicinal materials from floating on the liquid surface, increase the contact area between the medicinal materials and the solvent, thereby improving the actual extraction efficiency, and also facilitating the taking of the medicinal materials and the use of the medicinal solution;
[0014] (ii) After soaking for a period of time, the filter cage is driven upward by the cylinder, so that the distance between the two sets of grinding teeth is gradually reduced, thereby squeezing the medicinal material fragments in the filter cage, and then the pressing plate is driven by the motor to rotate in the filter cage. The staggered distribution design of the two sets of grinding teeth can be used to grind and squeeze the medicinal material fragments in the filter cage, which is beneficial to improve the actual extraction efficiency.

[0027] Specifically, the multiple grinding teeth 6 on the bottom surface of the inner cavity of the filter cage 3 are distributed in an annular array to form n first concentric rings, and the n first concentric rings are distributed at equal intervals from the inside to the outside, and the multiple grinding teeth 6 on the lower end surface of the pressing plate 5 are distributed in an annular array to form n-1 second concentric rings, and the second concentric rings are staggered with the first concentric rings;
[0028] n is a natural number greater than 1;
[0029] The first concentric ring and the second concentric ring are both formed by a plurality of grinding teeth 6 in an annular array;
[0030] like Figure 4 As shown, the bottom surface of the inner cavity of the filter cage 3 has three first concentric rings, and a grinding tooth 6 is also installed at the center of the innermost first concentric ring. The lower end surface of the pressing plate 5 has two second concentric rings. When the pressing plate 5 is slidably inserted into the filter cage 3, the distance between the two groups of grinding teeth 6 is shortened, and the second concentric ring moves to the gap between the two adjacent first concentric rings, which can fully squeeze the medicinal material fragments in the filter cage 3 so as to squeeze the juice of the medicinal material.
