Description

Technical Field

[0001] The utility model relates to the technical field of angelica polysaccharide extraction, in particular to a angelica polysaccharide extraction device. Background Art

[0002] Angelica dahurica is a tall perennial herb, 1-2.5 meters tall, with a cylindrical root and a stem base 2-5 centimeters in diameter. Its basal leaves are pinnately divided, and its compound umbels are terminal or lateral. Its fruit is oblong to ovate. Its root is used as medicine, dispelling dampness, draining pus and promoting tissue regeneration, and promoting blood circulation and relieving pain. It is primarily used to treat colds, headaches, rhinitis, and toothaches. It is also used as a spice for treating leucorrhea, painful boils, and swellings. It is cultivated in some northern provinces, mostly for local consumption, with a few exported. It typically grows under forests, along forest edges, beside streams, in thickets, and in valley grasslands. As a traditional Chinese medicine, Angelica dahurica has multiple benefits, with its polysaccharides being a key ingredient. Extraction of these polysaccharides requires a variety of processes for refined extraction.

[0003] At present, a Chinese patent with the announcement number CN216934789U discloses a device for extracting polysaccharides from angelica dahurica, comprising a tank body, a leg frame fixedly mounted on the bottom of the outer side of the tank body, a motor disposed on the top of the tank body, a rotating shaft fixedly mounted on the output end of the motor, a plurality of grinding blades fixedly mounted on the outer side of the rotating shaft, a plurality of scrapers fixedly mounted on the outer side of the rotating shaft, a feeding cylinder connected to the top of the feeding cylinder, a sealing cover movably mounted on the top of the feeding cylinder, an air pump disposed on the top of the tank body, and an air inlet pipe connected to the output end of the air pump. By providing the air pump and the bent delivery pipe, the reaction time and reaction conditions inside the tank body can be increased, the extraction efficiency can be accelerated, and the overall use effect can be increased. At the same time, the bent delivery pipe can be used to grind and extract the internal material twice or tertiarily, further increasing the extraction efficiency and the effect of component analysis, further improving production efficiency, and having a good use effect.

[0004] However, when the above device is in use, the ground angelica extract is filtered naturally under the action of its own gravity in conjunction with the filter plate. The filtration of the angelica extract is limited, and a large amount of angelica extract still remains on the top of the filter plate, resulting in poor filtration effect. In addition, the long filtration process may cause the active ingredients in the angelica extract to undergo chemical reactions such as oxidation and decomposition due to contact with air, and even affect the quality of the final product.

[0005] Therefore, it is necessary to provide a device for extracting polysaccharides from Angelica dahurica to solve the above technical problems. Utility Model Content

[0028] The filtering mechanism includes a filter screen plate 3 fixedly connected to the bottom of the inner wall of the extraction box 1, a connecting plate 4 with a plurality of holes is provided above the filter screen plate 3, a connecting rod 5 is fixedly connected to one side of the top of the connecting plate 4, and a rotating rod 6 is rotatably connected to one side of the connecting rod 5 through a bearing. The inner wall of the extraction box 1 is provided with a rotating groove 7 arranged in an inclined manner, and the inner wall of the rotating groove 7 forms a rolling fit with the rotating rod 6.

[0029] The bottom of the connecting plate 4 is rotatably connected to a limit rod 8 that passes through the filter screen plate 3 through a bearing. The limit rod 8 forms a sliding fit with the filter screen plate 3. The surface of the limit rod 8 surrounds the limit spring 9. The top of the limit spring 9 is fixedly connected to the connecting plate 4, and the bottom of the limit spring 9 is fixedly connected to the filter screen plate 3. The limit rod 8 can cooperate with the filter screen plate 3 to limit the connecting plate 4.

[0030] An adjusting block 10 is provided on the top of the connecting plate 4, and an adjusting shaft 11 is fixedly connected to the bottom of the adjusting block 10. The adjusting shaft 11 is rotatably connected to the connecting plate 4 through a bearing. The adjusting block 10 can cooperate with the adjusting shaft 11 to facilitate the rotation operation of the connecting plate 4, and motion interference can be generated on the surface.

[0031] The top of the adjusting block 10 is tilted, and an L-shaped adjusting rod 12 is provided on the top of the adjusting block 10.
