Description

Technical Field

[0001] The invention belongs to the technical field of medicinal liquid purification equipment, and in particular relates to a high-efficiency automatic extraction and concentration processing device for traditional Chinese medicine. Background Art

[0002] Traditional Chinese medicine (TCM) is a common ingredient in daily life, and its preparation has shifted from traditional manual methods to automated production. Many TCM manufacturers are considering how to incorporate mechanized production models into key steps of the preparation process. Traditional TCM production methods, which rely on decoction, alcohol precipitation, filtration, and concentration, have proven intractable and have proven inadequate, unable to adapt to the demands of modern pharmaceutical technology, the international market, and patient quality.

[0003] The main shortcomings of my country's medical equipment and instruments for the purification and preparation of Chinese herbal medicines are as follows: At present, pharmaceutical factories usually use heating tanks or steam to heat and boil the Chinese herbal raw materials after refining and boiling, and distill and purify the raw materials by continuously heating the Chinese herbal raw materials. When heating the Chinese herbal raw materials by heating tanks or steam, the Chinese herbal raw materials are heated indirectly, resulting in a large amount of Chinese herbal raw materials being difficult to quickly achieve overall uniform heating during the initial heating process, resulting in a long time for the extraction and concentration of Chinese herbal raw materials; and in the process of heating the Chinese herbal raw materials by traditional heating tanks, the liquid level of the medicinal liquid will gradually decrease during the concentration process, and the traditional heating tank only has overall heating, and will not change the heating position with the change of the liquid level, resulting in uneven heating of the medicinal liquid, resulting in a long time for the extraction and concentration of Chinese herbal raw materials.

The rotating bracket 22 is a cylindrical hollow structure and includes a plurality of longitudinal liquid grooves 23 . Each of the longitudinal liquid grooves 23 is provided with a plurality of stirring plates 24 .

[0031] The liquid stirring plate 24 is arc-shaped, and the outer arc surface is tangent to the outer ring surface of the rotating bracket 22 and smoothly transitions therewith.

[0032] The exhaust assembly, the discharge pipe 3 and the feed pipe 2 in the storage tank 1 are arranged on the same side, and the exhaust assembly is arranged inward when multiple groups of heating tank groups are installed in a ring distribution.

[0033] Liquid inlet pipe groups and liquid outlet pipe groups are provided between the multiple groups of heating tank groups.

[0035] The left and right sides of the top block 21 have a smooth arc transition with the lower surface of the rotating plate 20 , so as to facilitate contact with the wear-resistant protrusions 27 to lift the cover plate 13 .

[0036] The principle of the present invention is as follows: when in use, first, the raw liquid medicine is fed into the multiple storage tanks 1 through the liquid inlet pipe group, and the raw liquid medicine in the storage tanks 1 is heated by the first heating rod 5 and the second heating rod 7. During this period, the stirring motor 8 drives the stirring shaft 10, and the stirring shaft 10 drives the rotating bracket 22 to rotate, and the liquid medicine is stirred by the stirring plate 24 to make the liquid medicine evenly heated;

[0037] When the liquid medicine in the storage tank 1 boils and produces water vapor, the pressure in the storage tank 1 increases due to the generation of water vapor, and the driving motor 18 is controlled to rotate, driving the rotating plate 20 to rotate. The rotation of the rotating plate 20 intermittently lifts the cover plate 13 on the storage tank 1 in each group of heating tanks through the lifting block 21, thereby achieving the effect of exhaust and pressure reduction, and removing water from the liquid medicine;

[0038] When the cover plate 13 closes the air outlet, the storage tank 1 remains relatively sealed, so that the temperature can be stabilized at a specified value, avoiding excessive temperature fluctuations that affect the properties of the liquid medicine.

[0039] By arranging multiple groups of nozzle assemblies on the floating plate 6, steam is sucked in from the top of the storage tank 1 through the pump body 34, and then pumped into the upper uniform air pipe 32 through the air supply pipe 35, and sent to the lower uniform air pipe 31 through multiple elastic vent pipes 33, and sprayed out through multiple arc nozzles 30. The high-pressure steam can flush the inner wall of the storage tank 1 to prevent the liquid from adhering to the inner wall of the storage tank 1 during the purification process. As the floating plate 6 floats up and down, the flushing position decreases with the decrease of the liquid level, thereby achieving the cleaning of the tank wall. The elastic vent pipe 33 has a certain elastic force and is used to maintain a tensioned state under the pull of the floating plate 6. When the floating plate 6 descends, the elastic vent pipe 33 extends. When the floating plate 6 floats up, the elastic vent pipe 33 contracts, and always maintains a tensioned state to prevent the rotating bracket 22 from affecting it.

[0040] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and is susceptible to numerous variations. Any simple modifications, equivalent variations, and modifications to the above embodiments based on the technical essence of the present invention are deemed to fall within the scope of protection of the present invention.
