AI Technical Summary
When ultrasound propagates in a medium, some of the sound wave energy is converted into heat energy due to the internal friction of the medium, causing the medium temperature to rise. This heat cannot be dissipated in time, and prolonged exposure to heat damages the effective components in the extract.
A device for extracting flavonoids from sow thistle was designed. It adopts a combination structure of heat-conducting components and driving components. Heat is discharged in time through heat-conducting rods, and the filter plate state is automatically switched after the extraction time is reached to prevent the extract from overheating.
This effectively avoids the damage to the active ingredients of the extract caused by prolonged heating, thus improving extraction efficiency and ingredient purity.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of extraction device technology, specifically to a device for extracting flavonoids from sow thistle. Background Technology
[0002] Sow thistle is a herbaceous plant belonging to the genus Sow thistle in the family Asteraceae. The whole plant is used medicinally, and its chemical composition contains a high amount of flavonoids. The extraction of flavonoids from medicinal plants often employs the hot reflux method, but prolonged heating can easily destroy the active ingredients. With the development of science and technology, ultrasonic technology is now used in its extraction. Extensive data shows that the strong stirring, vibration, and cavitation effects of ultrasound can disrupt cell structure and accelerate the dissolution of active substances.
[0003] A search revealed an ultrasonic extraction device with publication number CN211635308U, comprising a base, rollers, a support, an ultrasonic extraction tank, a mounting base, an ultrasonic transmitter, an inlet, an outlet, a control valve, a waste outlet, and a waste tank. In this ultrasonic extraction device, the ultrasonic transmitter emits ultrasonic waves through a through-hole into the ultrasonic extraction tank. The ultrasonic transmitter vibrates within the through-hole, and its bottom vibrates and generates noise in the mounting groove. A ring pad contacts the ultrasonic transmitter, reducing its vibration frequency, while a bottom pad reduces the vibration at the bottom of the ultrasonic transmitter. Simultaneously, the ring pad, while vibrating, transmits the vibration through the inner frame to the side protective pads and shock-absorbing pads, further reducing the vibration emitted by the ultrasonic transmitter and lowering the noise emitted during operation. This device effectively reduces the noise emitted during ultrasonic extraction, facilitating its widespread application.
[0004] The aforementioned patent still has some shortcomings, such as: when ultrasound propagates in a medium, due to the internal friction of the propagation medium, some of the sound wave energy will be absorbed by the medium and converted into heat energy, thereby raising the temperature of the medium. If the heat cannot be dissipated in time, it will still lead to prolonged heating, which in turn will destroy the effective components in the extract.
[0005] Therefore, we propose a device for extracting flavonoids from sow thistle to address the problems mentioned above. Summary of the Invention
[0006] The purpose of this invention is to provide a device for extracting flavonoids from sow thistle, in order to solve the problem mentioned in the background art that when ultrasound propagates in a medium, due to the internal friction of the propagation medium, some of the sound wave energy is absorbed by the medium and converted into heat energy, thereby increasing the temperature of the medium. The heat cannot be dissipated in time, which still leads to prolonged heating and thus destroys the effective components in the extract.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a sow thistle flavonoid extraction device, comprising an extraction tank and a top cover disposed on the top surface of the extraction tank, a feed pipe being fixedly connected through the top cover, a liquid inlet pipe and a discharge pipe being fixedly connected through the side wall of the extraction tank, a plurality of ultrasonic transmitters being fixedly connected to the bottom surface of the top cover, a porous sound-absorbing plate being fixedly disposed on the inner wall of the extraction tank, a plurality of heat-conducting components being symmetrically fixedly connected to the side wall of the porous sound-absorbing plate, a filter plate being fixedly connected to the bottom surface of the porous sound-absorbing plate, and a plurality of driving components being fixedly connected to the bottom surface of the filter plate at positions corresponding to the positions of the plurality of heat-conducting components, and the heat-conducting components being internally connected to the corresponding driving components through pipes.
[0008] Preferably, the heat-conducting component includes a heat-insulating shell, with multiple heat-conducting rods fixedly connected through the side wall of the heat-insulating shell, and a connecting pipe fixedly connected through the bottom surface of the heat-insulating shell.
[0009] Preferably, each of the heat-conducting rods has multiple fins fixedly disposed on its sidewall.
[0010] Preferably, a settling groove is formed on the top surface of the filter plate, a plurality of filter holes are formed on the bottom surface of the inner cavity of the settling groove, and a sealing plate is slidably arranged inside the settling groove.
[0011] Preferably, the drive assembly includes a piston cylinder fixedly connected to the bottom surface of the filter plate. A partition is fixedly connected to the inner top wall of the piston cylinder. A first piston is slidably connected between one end side wall of the partition and the inner wall of the piston cylinder. A second piston is slidably connected between the other end side wall of the partition and the inner wall of the piston cylinder. One end of the connecting pipe communicates with the side of the piston cylinder where the first piston is located. A sliding rod is fixedly connected to the top surface of the second piston. The top surface of the second piston is connected to the inner top wall of the piston cylinder by a spring, and the sliding rod passes through the inner ring of the spring.
[0012] Preferably, the slide rod is slidably disposed through the top wall of the piston cylinder, and the end of the slide rod away from the second piston is fixedly connected to the bottom surface of the sealing plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. Through the heat-conducting components, when the temperature rises, the heat is promptly conducted to the interior of the heat-conducting components via the heat-conducting rods and converted into the internal energy of the gas inside the heat-conducting components. The heat is then isolated by the heat-insulating shell. The fins increase the contact area with the mixture, thereby enabling the heat to be dissipated in a timely manner and preventing prolonged heating from damaging the effective components of the extract.
[0015] 2. Through the set drive components and filter plates, after a certain extraction time, the gas in the heat conduction components heats up to a certain level, which overcomes the elasticity of the spring and causes multiple slide rods to lift the sealing plate in the settling tank to a certain height. At this time, the filter plates are connected from top to bottom, and the residue of dried bitter lettuce powder is blocked above the filter plates. The flavonoid extract of bitter lettuce flows into the bottom of the filter plates through the filter holes, further preventing the effective components of the extract from being damaged by excessive heating time.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1: Please refer to Figures 1-5 A device for extracting flavonoids from sow thistle includes an extraction tank 1 and a top cover 2 disposed on the top surface of the extraction tank 1. A feed pipe 3 is fixedly connected through the top cover 2. An inlet pipe 4 and a discharge pipe 5 are fixedly connected through the side wall of the extraction tank 1. Multiple ultrasonic transmitters 6 are fixedly connected to the bottom surface of the top cover 2. A porous sound-absorbing plate 7 is fixedly disposed on the inner wall of the extraction tank 1. Multiple heat-conducting components 8 are symmetrically fixedly connected to the side wall of the porous sound-absorbing plate 7. A filter plate 9 is fixedly connected to the bottom surface of the porous sound-absorbing plate 7. Multiple drive components 10 are fixedly connected to the bottom surface of the filter plate 9 at positions corresponding to the multiple heat-conducting components 8, and the heat-conducting components 8 are connected to the interior of the corresponding drive components 10 through pipes.
[0026] The heat-conducting component 8 includes a heat-insulating shell 81, with multiple heat-conducting rods 82 fixedly connected through the side wall of the heat-insulating shell 81, and a connecting pipe 83 fixedly connected through the bottom surface of the heat-insulating shell 81.
[0027] Multiple fins 821 are fixedly installed on the side wall of each heat-conducting rod 82.
[0028] In this embodiment: Sow thistle powder and a certain volume of ethanol solution are added in a certain proportion through the feed pipe 3 and the liquid inlet pipe 4. The flavonoids of sow thistle are extracted by ultrasound through the ultrasonic transmitter 6, and the noise is reduced by the porous sound-absorbing plate 7. During the extraction process, the stirring, vibration and cavitation of the ultrasound can destroy the cell structure and accelerate the dissolution of effective substances. At the same time, the vibration of the ultrasound causes the medium to oscillate, resulting in heat generated by the friction between the media. When the temperature rises, the heat is promptly conducted to the interior of the heat-conducting component 8 through the heat-conducting rod 82 and converted into the internal energy of the gas inside the heat-conducting component 8. The heat is then isolated by the heat-insulating shell 81. The fins 821 increase the contact area with the mixture, thereby enabling the heat to be discharged in time and avoiding damage to the effective components of the extract by prolonged heating.
[0029] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figures 6-7 A settling groove 91 is provided on the top surface of the filter plate 9, and multiple filter holes 92 are provided on the bottom surface of the inner cavity of the settling groove 91. A sealing plate 93 is slidably arranged inside the settling groove 91.
[0030] The drive assembly 10 includes a piston cylinder 101 fixedly connected to the bottom surface of the filter plate 9. A partition 102 is fixedly connected to the inner top wall of the piston cylinder 101. A first piston 103 is slidably connected between one side wall of the partition 102 and the inner wall of the piston cylinder 101. A second piston 104 is slidably connected between the other side wall of the partition 102 and the inner wall of the piston cylinder 101. One end of the connecting pipe 83 is connected to the side of the piston cylinder 101 where the first piston 103 is located. A slide rod 105 is fixedly connected to the top surface of the second piston 104. The top surface of the second piston 104 is connected to the inner top wall of the piston cylinder 101 by a spring 106, and the slide rod 105 passes through the inner ring of the spring 106.
[0031] The slide rod 105 is slidably connected to the top wall of the piston cylinder 101, and the end of the slide rod 105 away from the second piston 104 is fixedly connected to the bottom surface of the sealing plate 93.
[0032] In this embodiment: the gas inside the heat-conducting component 8 expands after being heated, and the pressure of the gas expansion is transmitted to the drive component 10 through the connecting pipe 83. Hydraulic oil is filled between the first piston 103 and the second piston 104. Due to the setting of the spring 106, the first piston 103 will not be pushed by the pressure of the gas expansion before overcoming the elastic force of the spring 106. When a certain extraction time is reached, the gas inside the heat-conducting component 8 heats up to a certain level, and it overcomes the elastic force of the spring 106 to push the first piston 103 downward, so that the second piston 104 drives the slide rod 105 upward. Multiple slide rods 105 together lift the sealing plate 93 in the settling tank 91 to a certain height, so that the filter hole 92 at the bottom of the settling tank 91 is exposed. At this time, the filter plate 9 is connected vertically, and the residue of the dried bitter lettuce powder is blocked above the filter plate 9. The liquid flows into the bottom of the filter plate 9 through the filter hole 92, further preventing the effective components of the extract from being damaged by excessive heating time. Finally, the liquid is discharged through the discharge pipe 5 to obtain the flavonoid extract of bitter lettuce.
[0033] Working principle: Pre-treated dried sow thistle powder is added through feed pipe 3 in a suitable ratio, and a certain volume of ethanol solution is added through liquid inlet pipe 4. The ultrasonic transmitter 6 is then activated to extract sow thistle flavonoids. During the extraction process, sound absorption and noise reduction are achieved through porous sound-absorbing plate 7. Heat is transferred to the interior of heat-insulating shell 81 through heat-conducting rod 82 and fins 821, and converted into the internal energy of the gas inside. After a certain extraction time, the pressure of the gas due to heat expansion is transferred to the interior of drive assembly 10 and can overcome the elastic force of spring 106. At this time, the first piston 103 drives the second piston 104 to slide upward through the hydraulic oil filled between the first piston 103 and the second piston 104, so that the slide rod 105 can lift the sealing plate 93. At this time, the filter hole 92 connects the upper and lower parts of the filter plate 9, and the sow thistle flavonoid extract is filtered through the filter hole 92 and flows out through discharge pipe 5.
