[0002] Plants are rich in various nutrients and active ingredients, which can be widely used in the pharmaceutical, food, health, and beauty industries. Plant extracts are products made from plants as raw materials. They are obtained and concentrated through a physicochemical extraction and separation process according to the intended use of the final product, without changing the structure of the active ingredients.

[0003] Most existing plant extraction filtration devices use a single filter structure for filtration. The filter structure is slow without external force, resulting in low plant extraction efficiency. Before extracting the plant material, a separate crushing device is needed to cut and crush the plant material, and then the crushed plant material is used for extraction. This process requires continuous transfer of plant material, which is labor-intensive. In addition, the existing plant extraction filtration devices are inconvenient to clean the plant filter residue. Summary of the Invention

Before entering the extraction filtration tank, the plant material is crushed by a crushing component inside the crushing mechanism, eliminating the need for separate crushing equipment, saving time and effort. The filter cylinder assembly is simple and easy to disassemble, facilitating the cleaning of plant residues inside, thus solving the technical problems mentioned in the background section.

[0022] This application provides a plant extraction filtration device. The filter cylinder assembly rotates during extraction, applying centrifugal force to the plant material. Under the action of centrifugal force and its own gravity, the plant material comes into full contact with the extraction solvent, improving the plant extraction efficiency. Before entering the extraction filtration tank, the plant material is crushed by the crushing component inside the crushing mechanism, eliminating the need for separate crushing equipment, saving time and effort. The filter cylinder assembly is simple and easy to disassemble, and the plant residue inside the filter cylinder assembly is easy to clean, solving the technical problems mentioned in the background art.

[0023] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example 1

[0024] Please see Figure 1-10This invention provides a technical solution: a plant extraction and filtration device, comprising an extraction and filtration tank 1 and a crushing mechanism 10. The extraction and filtration tank 1 has a filter cylinder assembly 2 installed inside, which includes a filter screen assembly 3 and a feed inlet 5. A rotary drive base 6 is installed at the bottom of the extraction and filtration tank 1. An electric heating tube 8 is installed on the inner wall of the extraction and filtration tank 1. A crushing assembly 11 is installed inside the crushing mechanism 10. An ultrasonic transducer 20 is installed at the bottom of the extraction and filtration tank 1. A temperature controller 21, including a temperature sensing probe, is installed on the outer surface of the extraction and filtration tank 1. The plant material is crushed by the crushing assembly 11 inside the crushing mechanism 10. The crushed plant material enters the filter cylinder assembly 2 through the feed inlet 5. A certain amount of extraction solvent is introduced into the extraction and filtration tank 1 through a solvent inlet pipe 17. The solvent soaks the plant material for extraction. During the extraction process, the electric heating tube 8 is energized to heat the extraction solvent. The temperature sensing probe of the temperature controller 21 monitors the temperature of the extraction solvent in real time and controls the temperature to keep it within the optimal range, thereby improving the quality of the plant extraction.

[0025] Among them, the ultrasonic transducer 20 is connected to the ultrasonic generator to perform ultrasonic extraction. It utilizes the strong vibration and cavitation effect generated by ultrasonic waves to accelerate the release, diffusion and dissolution of substances in plant cells into the solvent. At the same time, it can maintain the structure and biological activity of the extracted substances without change, thereby improving the plant extraction efficiency.

[0026] When the plant material is placed inside the filter cylinder assembly 2 of the extraction filter tank 1, the plant material is crushed by the crushing component 11 inside the crushing mechanism 10. When the extraction solvent is used for extraction, the plant material can fully contact and react with the extraction solvent, resulting in more complete extraction of the plant material, thereby improving the extraction quality and extraction efficiency. Moreover, there is no need to use a separate crushing device to crush the plant material, which saves time and effort, reduces labor intensity, and improves the functionality of the extraction filter tank 1.

[0027] In some examples, the bottom end of the filter cartridge assembly 2 is provided with a plug post 4, and one end of the rotary drive base 6 is equipped with a retainer 7. The plug post 4 is inserted into the inside of the retainer 7, and the retainer 7 and the plug post 4 are fixedly connected by a slot. The rotary drive base 6 has a built-in motor, which includes an output shaft and is fixedly connected to the retainer 7. When the motor inside the rotary drive base 6 is working, it can drive the retainer 7 to rotate relative to the extraction filter tank 1. Since the plug post 4 at the bottom end of the filter cartridge assembly 2 is inserted and fixedly inserted into the inside of the retainer 7, when the retainer 7 rotates relative to the extraction filter tank 1, the retainer 7 drives the filter cartridge assembly 2 to rotate synchronously relative to the extraction filter tank 1.

[0028] Applying a certain external force will allow the plug pin 4 to be inserted into the card holder 7, thus fixing the two together. When disassembling, applying a certain external force will separate the plug pin 4 from the card holder 7.

[0029] When the filter cartridge assembly 2 rotates, it drives the plant material inside to rotate synchronously, applying centrifugal force to the plant material. Under the action of centrifugal force and its own gravity, the plant material comes into full contact with the extraction solvent, thereby improving the extraction efficiency.

[0030] Since the extraction solvent can penetrate the filter screen of the filter cartridge assembly 2, while the plant material cannot, the plant residue from which the effective substances are extracted is placed inside the filter cartridge assembly 2 during the plant extraction process. The extract and plant residue are then automatically filtered out by the filter cartridge assembly 2.

[0031] In some examples, the top of the extraction filter tank 1 is equipped with a mounting base 9, the crushing mechanism 10 is installed on the upper end of the mounting base 9, and a retaining edge 22 is welded and fixed to the lower end face of the mounting base 9. The upper end face of the extraction filter tank 1 is provided with a groove, and the retaining edge 22 is embedded in the inside of the groove. The retaining edge 22 and the groove are fixedly connected by a retaining groove. The mounting base 9 and the crushing mechanism 10 are detachable, and the mounting base 9 and the extraction filter tank 1 are detachable. By applying a certain external force, the retaining edge 22 at the bottom of the mounting base 9 can be moved out of the inside of the groove, thereby disassembling the mounting base 9. After disassembly, the top of the extraction filter tank 1 is unobstructed. At this time, by applying a certain external force, the insertion post 4 and the retaining base 7 can be separated, and the filter cylinder assembly 2 can be moved out of the inside of the extraction filter tank 1 for cleaning.

[0032] In some examples, the crushing assembly 11 includes a fixed disk 12, with a motor 13 mounted on the upper end of the fixed disk 12 and a drive roller 14 mounted on the lower end of the fixed disk 12. Blades 15 are mounted on the drive roller 14, and there are three sets of blades 15. Multiple sets of through slots 16 are opened on the fixed disk 12. The motor 13 drives the drive roller 14 to rotate, and the drive roller 14 drives the three sets of blades 15 to rotate synchronously. The plant material enters through the multiple sets of through slots 16 and is cut and crushed by the rotating blades 15. The crushed plant material falls into the interior of the filter cartridge assembly 2 through the lower outlet of the crushing mechanism 10, realizing feeding. After feeding is completed, the extraction solvent is introduced.

[0033] In some examples, a solvent inlet pipe 17 is installed on one side of the extraction filter tank 1, and an extract drain pipe 18 is installed on the other side of the extraction filter tank 1. Both the extract drain pipe 18 and the solvent inlet pipe 17 are equipped with valves. A flow guide seat 19 is provided at the bottom of the extraction filter tank 1. The flow guide seat 19 serves to guide the flow and facilitate the drainage. The solvent inlet pipe 17 is connected to the inlet pipe, and the extract drain pipe 18 is connected to the drain pipe. When the valve of the solvent inlet pipe 17 is opened, a measured amount of extraction solvent enters the extraction filter tank 1 through the solvent inlet pipe 17. The solvent inlet pipe 17 makes full contact with the plant raw material through the filter screen assembly 3 for extraction. After extraction, the valve of the extract drain pipe 18 is opened, and the extract is discharged through the extract drain pipe 18. The plant residue from which the effective substances have been extracted is placed inside the filter cartridge assembly 2. The extract and plant residue are automatically filtered out by the filter cartridge assembly 2.

[0034] In the specific work process: The motor 13 drives the drive roller 14 to rotate, which in turn drives three sets of blades 15 to rotate synchronously. Plant materials enter through multiple channels 16 of the crushing assembly 11 and are cut and crushed by the rotating blades 15. The crushed plant materials fall into the filter cylinder assembly 2 through the lower outlet of the crushing mechanism 10, thus achieving feeding. After feeding, the extraction solvent is introduced, and the valve of the solvent inlet pipe 17 is opened. A measured amount of extraction solvent enters the extraction filter tank 1 through the solvent inlet pipe 17, ensuring full contact between the filter screen assembly 3 and the plant materials. The electric heating tube 8 is energized to heat the extraction solvent. The temperature sensor of the temperature controller 21 monitors the temperature of the extraction solvent in real time and controls the temperature to ensure proper extraction. The temperature is always kept within the optimal range. The motor inside the rotating drive base 6 works, driving the card holder 7 to rotate relative to the extraction filter tank 1. The card holder 7 drives the filter cylinder assembly 2 to rotate synchronously relative to the extraction filter tank 1. When the filter cylinder assembly 2 rotates, it drives the plant material inside to rotate synchronously, applying centrifugal force to the plant material. Under the action of centrifugal force and its own gravity, the plant material comes into full contact with the extraction solvent. At the same time, the ultrasonic transducer 20 is connected to the ultrasonic generator to perform ultrasonic extraction, which accelerates the extraction speed. After the extraction is completed, the valve of the extract drain pipe 18 is opened, and the extract is discharged through the extract drain pipe 18. The plant residue from which the effective substances have been extracted is placed inside the filter cylinder assembly 2.

[0035] By adopting the above technical solution: The ultrasonic transducer 20 is connected to an ultrasonic generator for ultrasonic extraction. Utilizing the strong vibrations and cavitation effect generated by ultrasound, it accelerates the release, diffusion, and dissolution of substances within plant cells into the solvent. Simultaneously, it maintains the structure and biological activity of the extracted substances, improving plant extraction efficiency. When the filter cartridge assembly 2 rotates, it drives the plant material inside to rotate synchronously, applying centrifugal force. Under the influence of centrifugal force and its own gravity, the plant material makes full contact with the extraction solvent, further improving extraction efficiency. Because the extraction solvent can penetrate the filter screen of the filter cartridge assembly 2, while the plant material… The filter screen of the filter cartridge assembly 2 cannot penetrate the filter. Therefore, during the plant extraction process, the plant residue from which the effective substances are extracted is placed inside the filter cartridge assembly 2. The extract and plant residue are automatically filtered out by the filter cartridge assembly 2. Before entering the extraction filter tank 1, the plant raw material is crushed by the crushing component 11 inside the crushing mechanism 10. The plant raw material can fully contact and react with the extraction solvent, resulting in more complete extraction of the plant raw material, thereby improving the extraction quality and extraction efficiency. Moreover, there is no need to use a separate crushing device to crush the plant raw material, saving time and labor, reducing labor intensity, and improving the functionality of the extraction filter tank 1. Example 2

[0036] Based on Example 1, this example describes the specific structure of the filter cartridge assembly 2 in a plant extraction filtration device, such as... Figure 8 , Figure 9 and Figure 10 As shown, the filter cartridge assembly 2 includes a first filter cartridge 23, a second filter cartridge 24, and a third filter cartridge 25. The first filter cartridge 23 is located inside the second filter cartridge 24, and the second filter cartridge 24 is located inside the third filter cartridge 25. The first filter cartridge 23 performs a first filtration of the extract, the second filter cartridge 24 performs a second filtration of the extract, and the third filter cartridge 25 performs a third filtration of the extract. The plant residues in the extract are removed through three filtrations, thereby improving the extraction quality and facilitating subsequent processing of the extract.

[0037] In some examples, the first filter cartridge 23 includes a first filter screen 26, the second filter cartridge 24 includes a second filter screen 27, and the third filter cartridge 25 includes a third filter screen 28. The extraction solvent can pass through the first filter screen 26, the second filter screen 27, and the third filter screen 28, while the solid plant material cannot pass through the first filter screen 26, the second filter screen 27, and the third filter screen 28. Therefore, during the plant extraction process, the plant residue from which the effective substances are extracted is placed inside the filter cartridge assembly 2, and the extract and plant residue are automatically filtered out by the filter cartridge assembly 2.

[0038] In some examples, a first filtration chamber is provided between the first filter cylinder 23 and the second filter cylinder 24, and a second filtration chamber is provided between the second filter cylinder 24 and the third filter cylinder 25. During drainage, the extract filtered by the first filter screen 26 enters the first filtration chamber, then enters the second filtration chamber after being filtered by the second filter screen 27, and then is discharged after being filtered by the third filter screen 28. Plant residues in the extract are removed through three filtrations, thereby improving the extraction quality.

[0039] In some examples, the bottom end of the first filter cartridge 23 is provided with a first base 29, the bottom end of the second filter cartridge 24 is provided with a second base 30, and the bottom end of the third filter cartridge 25 is provided with a third base 31.

[0040] In some examples, multiple sets of first magnetic blocks 32 are installed on the second chassis 30, multiple sets of second magnetic blocks 33 are installed on the third chassis 31, and the third chassis 31 is magnetically fixed to the second chassis 30, and the second chassis 30 is magnetically fixed to the first chassis 29.

[0041] When assembling the first filter cartridge 23, the second filter cartridge 24, and the third filter cartridge 25, the second base 30 of the second filter cartridge 24 is embedded inside the third base 31 of the third filter cartridge 25. The third base 31 and the second base 30 are magnetically fixed together by the second magnetic block 33, thereby fixing the second filter cartridge 24 and the third filter cartridge 25. The first base 29 of the first filter cartridge 23 is embedded inside the second base 30 of the second filter cartridge 24. The second base 30 and the first base 29 are magnetically fixed together by the first magnetic block 32, thereby fixing the second filter cartridge 24 and the first filter cartridge 23. The assembly of the first filter cartridge 23, the second filter cartridge 24, and the third filter cartridge 25 is completed.

[0042] During disassembly, only a certain external force needs to be applied to overcome the magnetic attraction to separate the first filter cylinder 23, the second filter cylinder 24, and the third filter cylinder 25. After the filter cylinder assembly 2 is taken out from the inside of the extraction filter tank 1 and disassembled, the plant residue inside the filter cylinder assembly 2 can be cleaned, which is convenient.

[0043] In the specific work process: Assemble the filter cartridge assembly 2 by embedding the second base 30 of the second filter cartridge 24 into the third base 31 of the third filter cartridge 25. The third base 31 and the second base 30 are magnetically fixed together by the second magnetic block 33, thereby fixing the second filter cartridge 24 and the third filter cartridge 25. Embed the first base 29 of the first filter cartridge 23 into the second base 30 of the second filter cartridge 24. The second base 30 and the first base 29 are magnetically fixed together by the first magnetic block 32, thereby fixing the second filter cartridge 24 and the first filter cartridge 23. Complete the assembly of the first filter cartridge 23, the second filter cartridge 24 and the third filter cartridge 25 to form the overall filter cartridge assembly 2. Insert the insertion post 4 at the bottom of the filter cartridge assembly 2 into the inside of the card holder 7 to fix the filter cartridge assembly 2. Fix the filter cartridge assembly 2 inside the extraction filter tank 1.

[0044] By adopting the above technical solution: The extraction process removes plant residues from the extract through three filtrations, improving extraction quality and facilitating subsequent processing of the extract. The filter cartridge assembly 2 is detachable; when disassembling, only a certain external force needs to be applied to overcome the magnetic attraction to separate the first filter cartridge 23, the second filter cartridge 24, and the third filter cartridge 25. After removing and disassembling the filter cartridge assembly 2 from the inside of the extraction filter tank 1, the plant residues inside the filter cartridge assembly 2 can be cleaned, making cleaning convenient. No fasteners are required when assembling and disassembling the filter cartridge assembly 2, making assembly and disassembly convenient.

[0045] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
