The Chinese medicine extraction equipment is widely applicable to the Chinese medicine industry. Its main purpose is to detect the medicinal properties of Chinese medicine and conduct medicinal tests. The most commonly used extraction method for plant-based Chinese medicine in the laboratory is the distillation method. It generally consists of an iron frame, a separating funnel, a condenser tube connected to the separating funnel, etc. The condenser tube is butted with a flask. The medicine to be extracted is placed in the flask and heated. The evaporated Chinese medicine essential oil follows the water vapor into the condenser tube, cools down and then enters the separating funnel to be separated. The extract is discharged from the outlet of the separating funnel, so as to achieve the purpose of separation and extraction.

When conducting extraction experiments on a large number of plant-based Chinese medicines, it is easy for more Chinese medicine essential oil to be mixed in the water, and the extraction effect is poor and time-consuming and laborious.

By setting the feeding pipe 4, the mixed product can enter the liquid separation hopper 1. Both the liquid discharge cylinder 15 and the liquid separation hopper 1 are made of transparent materials, and the internal situation can be observed at any time.

[0022] As Figure 2 、 Figure 3 and Figure 4As shown, a connecting ring 18 is fixedly connected to the outer surface of the liquid discharge cylinder 15. The outer surface of the connecting ring 18 is rotatably connected to the inner surface of the adjusting pipe 2. By providing the connecting ring 18, the liquid discharge cylinder 15 can be rotatably connected to the adjusting pipe 2, so that the liquid discharge cylinder 15 will not fall off from the inside of the adjusting pipe 2.

[0027] The mixture of traditional Chinese medicine essential oil and water vapor flows into the separating funnel 1 through the feed pipe 4 after cooling. After reaching a certain amount and undergoing natural liquid separation, the experimenter inserts the sealing bolt 22 into the exhaust pipe 6, and then pulls the air extraction bolt 7 to extract part of the air in the liquid discharge cylinder 15 and the separating funnel 1 to form a negative pressure in the liquid discharge cylinder 15 and the separating funnel 1. Then, rotate the adjusting ring 3 so that the two circular through holes 9 and the two connecting through holes 19 are misaligned, and during the rotation, let the fixed ear 11 move from above one positioning ear 10 to above the other positioning ear 10, and pass the fixing bolt 12 through the inside of the fixed ear 11 and the positioning ear 10 to fix the adjusting ring 3, so as to seal the liquid discharge cylinder 15 and the separating funnel 1. Then, rotate the control valve 21 to open the discharge pipe 20, and push the adjusting bolt 16 to drive the rubber block 17 to move the solution in the separating funnel 1 and drain the water. When the water is almost drained, slowly push the adjusting bolt 16 to precisely control the discharge amount to avoid wasting the traditional Chinese medicine essential oil by draining it together with the water.
