Description

Technical Field

[0001] The utility model relates to the technical field of flavonoids extraction, in particular to an ultrasonic extraction device for flavonoids in kudzu root. Background Art

[0002] Pueraria root is the dried root of the leguminous plant Pueraria lobata, which can be used as a traditional Chinese medicinal material. The flavonoids in Pueraria root have many important physiological and biochemical effects on mammals and other types of cells due to their unique chemical structure. They are the active ingredients of many Chinese herbal medicines. In order to obtain them better, the Pueraria root needs to be crushed and then the flavonoids inside it need to be extracted for further processing and use.

[0003] Nowadays, there are many extraction devices to extract and process flavonoids in Pueraria root. However, compared with the traditional water boiling and alcohol precipitation processes, the ultrasonic extraction device has many advantages such as no need for high temperature, normal pressure extraction, high extraction efficiency, wide applicability and low cost. Therefore, it is widely used in the extraction operations of various substances nowadays, and naturally it is also widely used in the extraction operations of flavonoids in Pueraria root.

[0004] After searching, the existing patent (Announcement No.: CN213669646U) discloses a pueraria flavonoid separation and extraction device, including a housing, a crankshaft is rotatably connected between the inner side walls of the housing through a bearing, a sleeve is sleeved on the outer surface of the crankshaft, a connecting rod is fixedly connected to the outer surface of the sleeve, a slide rail is fixedly connected between the inner left and right walls of the housing, a slide plate is slidably connected between the two opposite sides of the slide rails, a plurality of knives are fixedly connected to the lower surface of the slide plate, and a first filter is fixedly connected between the inner side walls of the housing. The pueraria flavonoid separation and extraction device firstly cuts the bulk material into pieces by a cutting tool, and then further cuts the material into pieces by crushing teeth, thereby shortening the working time of grinding, and finally grinding and crushing by a grinding wheel, thereby achieving the effect of fully crushing the material, so that the processed material is in powder form, and the work efficiency is high during separation and extraction, which is convenient for separation and extraction of materials.

[0005] However, in the above scheme, it is inconvenient to mix quickly and comprehensively. In order to improve the extraction effect, it is usually necessary to add the corresponding extractant into the Pueraria solution, and then mix it thoroughly, let it stand, and then extract it. However, due to the limitation of sound wave decay factors, the ultrasonic action area is a ring, and an ultrasonic blank area is easily generated in the upper space inside the kettle, which leads to poor mixing effect and extraction effect of the mixed liquid in the upper part of the reactor, resulting in inconvenience in its use.

[0032] Example 2

[0033] Based on Example 1, a preferred embodiment of the ultrasonic extraction device for flavonoids in Pueraria root provided by the utility model is as follows: Figures 1 to 5As shown: the lifting component 1 includes a fixing bolt 104, which is opened at the middle position of one side of the fixing seat 2, and a servo motor 103 is fixedly connected to the middle position of one side of the top of the fixing seat 2, the output end of the servo motor 103 extends to the inside of the fixing bolt 104 and is fixedly connected to a threaded rod 105 through a coupling, and the surface of the threaded rod 105 is threadedly connected to a threaded plate 102 extending to the outside of the fixing seat 2, and the two ends of the top of the threaded plate 102 are fixedly connected to a connecting frame 101, and the top of one side of the connecting frame 101 is fixedly connected to one side of the cover plate 9.

[0037] Furthermore, an anti-slip protrusion 11 is fixedly connected at an equal angle to one end of the surface of the locking bolt 10, and the cross-section of the anti-slip protrusion 11 is arc-shaped. The arc-shaped anti-slip protrusion 11 is used to increase the contact friction between the user's fingers and the locking bolt 10, thereby making it easier for the user to turn the locking bolt 10.

The funnel-shaped large flow guide platform 13 can be used to guide the liquid inside the transparent reaction kettle 4 so that it can be discharged from the discharge pipe 12 faster and more thoroughly.

[0039] The working principle and use process of the utility model are as follows: first, the kudzu root solution and the extract are added into the transparent reaction kettle 4 through the feed hopper 7, and then the ultrasonic generator body 8 is started through the external device to realize the oscillation of the mixed liquid inside the transparent reaction kettle 4, and at the same time, the pneumatic telescopic rod 502 is started to drive the piston plate 503 to slide upward inside the mixing box 501, and then the mixed liquid inside the transparent reaction kettle 4 is sucked into the mixing box 501 through the conduit, so that the liquid level inside the transparent reaction kettle 4 drops, and then the pneumatic telescopic rod 502 is started to drive the piston The disc 503 descends to transport the mixed liquid in the mixing box 501 to the transparent reaction kettle 4, and then the piston disc 503 slides up and down back and forth, so that the mixing box 501 can reciprocally inhale and discharge the mixed liquid in the transparent reaction kettle 4, thereby accelerating the mixing rate of the mixed liquid in the transparent reaction kettle 4, which is convenient for improving the extraction efficiency of flavonoids in Pueraria root, and the funnel-shaped small guide platform 504 can be used to make the piston disc 503 descend to discharge the mixed liquid more thoroughly, avoiding the mixed liquid from remaining on the bottom wall of the mixing box 501;

[0040] After the mixing is completed, the mixed liquid is allowed to stand for a period of time to be separated into layers. After the separation is completed, the discharge pipe 12 can be opened to discharge the liquid in the lower layer of the transparent reaction kettle 4, and the layered liquid level can be observed through the transparent reaction kettle 4. When the layered liquid level drops to the lowest, the discharge pipe 12 is closed, and another container is taken out to receive the remaining liquid in the transparent reaction kettle 4 to achieve the extraction of flavonoids in Pueraria root. At the same time, the large funnel-shaped guide table 13 can be used to guide the liquid in the transparent reaction kettle 4 so that it can be discharged from the discharge pipe 12 faster and more thoroughly.

[0041] When it is necessary to clean the inner wall of the transparent reaction kettle 4, the locking bolt 10 can be rotated first until it is completely disengaged from the bolt hole 14, and then the servo motor 103 is started to drive the threaded rod 105 to rotate. The threaded rod 105 and the threaded plate 102 are matched with each other, so that the threaded plate 102 rises and drives the connecting frame 101 to move upward, and then the cover plate 9 can be raised to drive the ultrasonic generator body 8 to be completely disengaged from the inside of the transparent reaction kettle 4, so that the staff can thoroughly clean the inside of the transparent reaction kettle 4 to avoid the residual mixed liquid affecting the next batch of extraction processing of flavonoids in Pueraria root. At the same time, after the cleaning is completed, the servo motor 103 is started again to make the cover plate 9 descend to cover the top of the transparent reaction kettle 4, and the locking bolt 10 is rotated to lock it into the bolt hole 14, so as to avoid that during extraction, the mixed liquid inside the transparent reaction kettle 4 is splashed from the top of the transparent reaction kettle 4 due to vibration or impurities such as dust enter the inside of the transparent reaction kettle 4.
