[0002] The filtration of Chinese medicine is an important step in the preparation of Chinese medicine preparations. Its purpose is to remove impurities and insoluble substances in Chinese medicine, making the Chinese medicine more pure and easier to take. Chinese medicine filtration is usually carried out using filtering materials such as filter paper, filter cloth or filter. Before filtration, the filter needs to be washed with water to avoid contamination of the medicine. During the filtration process, it is necessary to control the filtration speed and pressure to avoid destroying the structure of the effective ingredients of the Chinese medicine and affecting the quality of the medicine.

[0003] During the operation of the specific embodiment, the inventors found the following defects:

[0004] In order to ensure the filtration quality, the existing Chinese medicine decoction filtration equipment usually needs to use two filtration devices for secondary filtration. This method is time-consuming and labor-intensive in the actual production process, and also increases the equipment cost of the enterprise. After multiple circulations, it is easy to cause differences in the filtration quality of the medicinal liquid.

The filter cartridge 1 41 is rotated by the centrifugal drive mechanism 3, and the medicinal residue and the medicinal liquid are separated by centrifugal force. The medicinal liquid is thrown out of the filter cartridge 41 and falls into the liquid collecting cartridge 1 42, and then flows into the filter cartridge 2 51 through the discharge hole 43 at its lower end. The liquid collecting cartridge 1 42 and the liquid collecting cartridge 2 52 are connected by a linkage shaft 7. The lower filter module 5 includes a filter cartridge 2 51 and a liquid collecting cartridge 2 52. In the technical solution, the side walls of filter cartridge 1 41 and filter cartridge 2 52 are both mesh structures, and the mesh size of filter cartridge 2 52 is smaller than that of filter cartridge 1 41.

[0038] In this embodiment, the discharge port 44 on the upper filter module 4 is externally connected to a solenoid valve. During the first filtration, the discharge port 44 is in a closed state, and the feed port 11 can be connected to a hose for extension for convenient loading. This device adopts a control system for automatic operation, wherein a low speed is used for the first filtration and a high speed is used for the second filtration.

[0039] The specific steps of using the Chinese medicine boiling and filtering device provided by the utility model are as follows:

[0040] Primary filtration: First, close the discharge port 44, and pour the boiled Chinese medicine into the filter cartridge 41 from the feed port 11. A hose can be connected to the feed port 11 to lead to the filter cartridge 41. The filtration time and speed of the two times are set through the external control system, and the centrifugal drive mechanism 3 is started. A low speed is used for the primary filtration, and the filter cartridge 41 rotates to throw out the Chinese medicine liquid and flow into the liquid collecting cylinder 42. At this time, the discharge hole 43 at the lower end of the liquid collecting cylinder 42 is open, and the medicine liquid flows into the filter cartridge 2 51 below. After the regular filtration, the centrifugal drive mechanism 3 is stopped. At a low speed, the medicine liquid and the medicine residue are preliminarily filtered. When there is still a small amount of medicine liquid in the medicine residue, small particles of medicine residue can be prevented from being thrown out and mixed into the filtered medicine liquid;

[0041] Isolation between the upper and lower parts: Start the lifting mechanism 2, and the two hydraulic cylinders 22 push the filter cartridge 1 41 downward. After the filter cartridge 1 41 is lowered, the linkage shaft 1 7 at the lower end is docked with the filter cartridge 2 51, so that the filter cartridge 1 41 and the filter cartridge 2 51 rotate simultaneously. During the lowering process, the filter cartridge 2 51 drives the linkage shaft 2 8 to descend together, pressing the sleeve 622 in the telescopic shaft assembly 62 against the collar 614, driving the self-locking assembly 61. After the pressure plate 613 moves horizontally, the silicone plug 615 seals the discharge hole 43, and the upper liquid collecting cartridge 1 42 is isolated from the lower filter cartridge 2 52;

[0042] Secondary filtration: Open the discharge port 44 and start the centrifugal drive mechanism 3. During the secondary filtration, a high speed is used. The filter cartridge 41 and the filter cartridge 2 51 rotate at the same time. After the high speed, the filter cartridge 1 41 further filters the medicinal residue with a small amount of liquid medicine, and the filtered liquid medicine is discharged from the discharge port 44; the liquid medicine in the filter cartridge 2 51 that has been filtered once flows into the liquid collecting cartridge 2 52 after the secondary filtration and is discharged from the discharge port 2 53.

[0043] In summary, the structural design of two groups of filtration modules connected by a common centrifugal drive mechanism can reduce the overall structure of the filtration device, greatly saving production and use space. The pure medicinal liquid and the medicinal liquid with medicinal residue particles can be separated through primary filtration and secondary filtration, and the filtration speed and pressure can be controlled to achieve batch filtration to avoid destroying the effective ingredients of traditional Chinese medicine, improve the quality of the medicine, save production steps to the greatest extent, and improve efficiency.
