[0025] It should be noted that, without conflict, the embodiments and the features and technical solutions in the embodiments in the present utility model can be combined with each other.

[0026] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0027] Embodiment 1

[0028] Please refer to Figure 1-3 , an ultrasonic-assisted dissolution extraction device, which includes a dissolution tank 1, an ultrasonic oscillator 2 built in the inner wall of the dissolution tank 1, an ultrasonic generator 3, a sieve tube 4 and a circulation pump 5. The ultrasonic generator 3 is electrically connected to the ultrasonic oscillator 2. The sieve tube 4 is built in the dissolution tank 1. The input end of the circulation pump 5 extends into the upper part of the dissolution tank 1. A liquid inlet pipe 6 is installed in the middle of the inner bottom wall of the dissolution tank 1. The output end of the circulation pump 5 is communicated with the input end of the liquid inlet pipe 6, and the output end of the liquid inlet pipe 6 extends into the sieve tube 4; Further, the ultrasonic oscillators 2 are circumferentially and uniformly distributed around the inner wall of the dissolution tank 1; The ultrasonic oscillator 2 is a conventional ultrasonic transducer known in the market; The central axes of the dissolution tank 1, the sieve tube 4 and the liquid inlet pipe 6 are collinear.

[0029] A flow guide is installed in the sieve tube 4. The flow guide includes an inner tube 7, a flow guide cylinder 8 sleeved outside the inner tube 7 and a feed bell mouth 9. The upper part of the feed bell mouth 9 is connected to the bottom of the inner tube 7, and the lower part of the feed bell mouth 9 is connected to the lower part of the feed bell mouth 9. A conical flow guide cover 10 is connected between the upper part of the inner tube 7 and the upper part of the flow guide cylinder 8. A cylindrical cloth channel is formed between the flow guide cylinder 8 and the inner wall of the dissolution tank 1.

[0030] The upper part of the inner tube 7 is fixedly installed with a spherical cloth fluid body 11 through a connecting rod; Further, the spherical cloth fluid body 11 is located directly above the inner tube 7; When the outflow pressure of the liquid inlet pipe is large, the spherical cloth fluid body 11 can block and limit the upward moving particles. Under the action of the spherical cloth fluid body 11, the raw material particles move away from the center of the inner tube 7, avoiding the continuous accumulation of the raw material particles above the inner tube 7 or the escape of the raw material particles above the sieve tube 4.

[0031] The inner bottom wall of the sieve tube 4 is in a conical constriction shape. The inner bottom wall of the sieve tube 4 is arranged in a conical constriction shape, which can make the raw material particles gather towards the liquid inlet pipe 6 in the middle of the sieve tube 4, so that the raw material particles can be smoothly flushed up by the pressurized extraction liquid.

[0032] Heating elements 20 are embedded and installed both at the bottom and in the circumferential wall of the dissolution tank 1; Further, the heating element 20 can be an electric heater or a steam heating pipe or other equivalent components with a heating effect on the dissolution tank 1; The extraction liquid in the dissolution tank 1 can be heated through the heating element 20 to further improve the dissolution efficiency of the raw material particles in the extraction liquid.

[0033] The ultrasonic vibrators 2 are evenly distributed at equal intervals along the inner wall of the sieve cylinder 4 in the up-and-down and inner-circle directions; arranged in this way, it can prompt the raw material particles to uniformly contact the ultrasonic waves emitted by the ultrasonic vibrators 2 during the movement process, so as to ensure that the raw material particles are in a high-frequency vibration state and improve the dissolution efficiency of the active ingredients in the raw material particles.

[0034] For the ultrasonic-assisted dissolution extraction device provided in this embodiment, the pressurized extraction liquid ejected through the liquid inlet pipe 6 acts on the raw material particles at the bottom of the sieve cylinder 4. The raw material particles move from the feed bell mouth 9 and the inner cylinder 7 to the upper part inside the sieve cylinder 4, and then enter the annular cylindrical cloth channel through the conical guide cover 10. The raw material particles flowing through the annular cylindrical cloth channel can be further dispersed, thereby improving the contact uniformity between the raw material particles and the ultrasonic wave source, enabling the ultrasonic waves to fully act on the raw material particles, improving the self-vibration effect of the raw material particles, and thus improving the dissolution efficiency of the active ingredients in the raw material particles in the extraction liquid.

[0035] Embodiment 2

[0036] The ultrasonic-assisted dissolution extraction device provided in Embodiment 1 is further optimized. Specifically, as Figure 1 and Figure 5 shown, a lifting drive cylinder 12 is installed on the dissolution tank 1. The output end of the lifting drive cylinder 12 is rotatably installed with a cantilever 13 and a rotation drive member 14 that provides power for the rotation of the cantilever 13. The sieve cylinder 4 is detachably installed on the cantilever 13. Specifically, the rotation drive member 14 is preferably a telescopic cylinder and a transmission rod. The telescopic cylinder is hingedly installed at the output end of the lifting drive cylinder 12. One end of the transmission rod is hinged to the telescopic cylinder, and the other end of the transmission rod is hinged to the cantilever 13; the rotation drive member 14 can also adopt other drive members such as a stepping motor that have the effect of driving the cantilever 13 to rotate; the sieve cylinder 4 is detachably connected to the cantilever 13 through bolts or pins, etc.

[0037] As Figure 4 shown, a through port allowing the liquid inlet pipe 6 to pass through is provided at the bottom of the sieve cylinder 4. An elastic sealing assembly is installed at the through port. The elastic sealing assembly includes two sliding sealing members symmetrically arranged on both sides of the through port. The sliding sealing member includes a mounting seat 15 fixedly installed at the bottom of the sieve cylinder 4, two guide rods 16 slidably installed on the mounting seat 15, a sealing block 17 fixedly installed at the ends of the two guide rods 16, and a spring 18 sleeved on the two guide rods 16. A semi-conical notch 19 is provided at the sealing block 17; further, one end of the spring 18 abuts against the sealing block 17, and the other end of the spring 18 abuts against the sealing block 17. The semi-conical notches on the two sealing blocks 17 form a conical notch after being closed. The small-diameter end of the conical notch is adjacent to the through port; the size of the through port fits the outer diameter of the liquid inlet pipe 6.

[0038] The ultrasonic-assisted dissolution extraction device provided in this embodiment can drive the cantilever 13 to drive the screen cylinder 4 to move upward by starting the lifting drive cylinder 12. Subsequently, by starting the rotation drive member 14, the cantilever 13 rotates, and the screen cylinder 4 is moved out from the upper part of the dissolution tank 1, which is convenient for centrally cleaning the raw material particle residues in the screen cylinder 4 and adding new raw material particles into the screen cylinder 4, improving the convenience of loading and unloading the raw material particles. In the natural state, under the action of the spring 18, the two blocking blocks 17 are closed to block the through hole to prevent the raw material particles in the screen cylinder 4 from escaping from the through hole. When the screen cylinder 4 is placed into the dissolution tank 1, under the action of the self-weight of the screen cylinder 4 and the raw material particles, the blocking blocks 17 tend to move downward. At this time, the top of the liquid inlet pipe 6 contacts the semi-conical notch, and the two blocking blocks 17 move away from each other until the liquid inlet pipe 6 is completely inserted into the through hole. Under the action of the spring 18, the blocking blocks 17 are tightly wrapped around the outer wall of the liquid inlet pipe 6, so as to effectively reduce the exposure of the raw material particles in the screen cylinder 4 through the through hole. At the same time, the liquid inlet pipe 6 and the bottom of the screen cylinder 4 are integrated to prevent the screen cylinder 4 from shaking excessively during use.

[0039] The use process of the ultrasonic-assisted dissolution extraction device provided by the present utility model is as follows: By injecting the extraction liquid into the dissolution tank 1, putting the raw material particles into the screen cylinder 4, and starting the circulation pump 5, the circulation pump 5 pressurizes the extraction liquid in the upper part of the dissolution tank 1 and injects it into the bottom of the screen cylinder 4 through the liquid inlet pipe 6. Under the action of the pressurized extraction liquid ejected at the liquid inlet pipe 6, the raw material particles in the screen cylinder 4 move to the upper part of the screen cylinder 4 through the feeding bell mouth 9 and the inner cylinder 7 and contact the spherical fluid distributor 11. The raw material particles enter the annular cylindrical cloth channel evenly dispersed through the conical deflector 10 and contact the ultrasonic waves emitted by the ultrasonic vibrator 2. The raw material particles fall back to the upper part of the liquid inlet pipe 6 through the conical constriction at the bottom of the screen cylinder 4, and so on in a cycle, so that the active ingredients in the raw material particles are fully and quickly dissolved in the extraction liquid. When the dissolution operation of the active ingredients in the raw material particles is completed, start the lifting drive cylinder 12, which can drive the cantilever 13 to drive the screen cylinder 4 to move upward. Subsequently, start the rotation drive member 14, the cantilever 13 rotates, and the screen cylinder 4 is moved out from the upper part of the dissolution tank 1, and then the screen cylinder 4 and the raw material particle residues in the screen cylinder 4 can be unloaded.
