Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine extraction, in particular to a traditional Chinese medicine extraction process. Background Art

[0002] Traditional Chinese medicine is China's traditional medicine with a long history. However, due to the relatively backward production technology of traditional Chinese medicine, especially the extraction and separation technology, it is difficult to achieve product quality control. Basically, it is extracted by the "one-pot" method, or by reflux extraction with water or ethanol. The extraction efficiency is low and the energy consumption is high. At the same time, as people's understanding of the medicinal and nutritional value of natural products gradually deepens, a wave of research on active ingredients in natural products has been set off worldwide.

[0003] The existing Chinese patent with publication number CN115301355B includes a high-temperature box, a liquid outlet condenser tube, an extrusion crushing and stirring mechanism and a box cover. The high-temperature box is provided with an extrusion crushing and stirring mechanism, which includes a rotating shaft, stirring and crushing blades, an extrusion shaft and a rotating drive. The rotating shaft is rotatably arranged in the high-temperature box, and stirring and crushing blades are fixedly arranged on the outside of the rotating shaft. Two extrusion shafts are rotatably arranged in the high-temperature box, and the rotating drive can drive the extrusion shaft and the stirring and crushing blades to rotate and crush at the same time.

[0004] When the above device is in use, the diseased plants can be crushed by the stirring and crushing leaves, so that they become smaller in shape and the outer wall can be fully in contact with the hot air. At the same time, the crushed plants are stirred by the stirring of the stirring and crushing leaves so that they can be heated evenly. However, in actual use, when there are many medicinal materials, it is easy to cause the Chinese medicinal materials to accumulate and become thicker, and it is difficult for the Chinese medicinal materials to be evenly heated to extract the medicinal juice, resulting in waste of Chinese medicinal materials. Therefore, it is difficult to turn the Chinese medicinal materials back and forth during the extraction process.

[0005] Therefore, we proposed a Chinese medicine extraction process. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The motor drives the rotating shaft to rotate on the n-shaped frame. The crushing blades arranged on the rotating shaft and the crushing barrel are arranged so that the crushing blades on the crushing barrel and the rotating shaft are placed alternately. First, the Chinese medicinal materials are placed inside the feed hopper. The crushing blades are driven by the rotating shaft to rotate on the fixed axis, and the crushing blades on the crushing barrel remain stationary. Therefore, the crushing blades on the rotating shaft rotate to crush the Chinese medicinal materials inside the feed hopper and discharge them into the heating box.

[0016] By setting the first filter plate on the rotating shaft, the rotating shaft can drive the first filter plate to rotate synchronously on the inner wall of the heating box. Then, the Chinese medicinal materials are scattered around under the action of the centrifugal force of the rotation of the first filter plate.

[0017] Second, along with the fixed-axis rotation of the rotating shaft, the columnar block can be synchronously rotated along with the rotating shaft, so that the support rod can drive the slider to move up and down and reciprocate along the inner wall of the rectangular frame under the action of the W-shaped groove, and the slider can drive the moving rod to move up and down and reciprocate synchronously, through the conical extrusion block arranged on the moving rod, the moving rod can push the conical extrusion block to reciprocately squeeze the Chinese medicinal materials on the surface of the first filter plate, so that the first filter plate can squeeze out the medicinal juice inside the Chinese medicinal materials, further improving the extraction efficiency.

[0018] 3. As the slider moves up and down and back and forth, the pull rods on both sides can pull the moving block to move back and forth horizontally towards or away from each other on the outer contour of the cylindrical rod under the action of the slider, and the arc scraper is fixedly supported on the moving block, so that the arc scrapers on both sides can move back and forth horizontally towards or away from each other synchronously with the moving block, so that the arc scraper can turn the Chinese medicinal materials at the edge of the first filter plate toward the center position, and at the same time turn over the Chinese medicinal materials on the surface of the first filter plate, thereby avoiding one side of the Chinese medicinal materials sticking to the surface of the first filter plate, resulting in uneven heating, and further improving the extraction efficiency of the Chinese medicinal materials.

[0019] Fourth, by arranging a second pulley on the rotating shaft, the second pulley can be synchronously rotated along with the rotating shaft, and the transmission belt can drive the first pulley and the spiral rod to synchronously rotate along the fixed axis under the action of the second pulley, so that the spiral rod can move the Chinese medicinal materials that have not been completely extracted at the bottom of the cylindrical shell toward the top, so that the feeding pipe can put the Chinese medicinal materials moved by the spiral rod onto the first filter plate for secondary extraction, thereby improving the utilization rate of the Chinese medicinal materials and reducing the extraction cost.

The top of the screw rod 25 is coaxially fixedly connected to a first pulley 26, and the end of the rotating shaft 5 is fixedly connected to a second pulley 27 at a position corresponding to the first pulley 26. The second pulley 27 and the first pulley 26 are provided with a transmission belt 28 on the outer contour of the sliding groove to drive the screw rod 25 to rotate on a fixed axis.
