[0038] Combination Figure 1-2As shown, the embodiment of the present disclosure provides a purification device for plant extracts, including: a pretreatment structure 100, a conveying structure 200, a separation component 300, a detection component 400 and a controller component 500. The pretreatment structure 100 is used to crush and remove impurities from plants; the conveying structure 200 includes a conveying pipeline 201 and a discharge control valve 202, one end of the conveying pipeline 201 is connected to the pretreatment structure 100, and the discharge control valve 202 is arranged on the conveying pipeline 201 to adjust the conveying amount of the plant; the separation component 300 includes a tank body 301, a semi-permeable membrane body 302, an electric telescopic rod 303 and a pressure structure 304, and a feed port is provided on the side wall of the tank body 301, and the feed port is connected to the conveying structure 304. The other end of the feeding pipe 201 is connected, there are multiple semi-permeable membrane bodies 302, and along the height direction of the tank body 301, the multiple semi-permeable membrane bodies 302 are evenly arranged in the tank body 301, the electric telescopic rod 303 is connected to the multiple semi-permeable membrane bodies 302, and the electric telescopic rod 303 is used to drive the multiple semi-permeable membrane bodies 302 to move and adjust the relative position between each semi-permeable membrane body 302 and the feed port, and the pressure structure 304 is arranged on the tank body 301 and is connected to the inside of the tank body 301. 304 is used to adjust the internal pressure of the tank body 301 and provide a force to penetrate the semipermeable membrane for the purification of the plant extract; the detection component 400 is used to obtain the purification accuracy requirement information of the plant extract and the position information of each semipermeable membrane body 302, as well as the characteristic data information of the semipermeable membrane body 302; the controller component 500 is connected to the detection component 400, the electric telescopic rod 303, the pressure structure 304 and the discharge control valve 202, and is used to control the electric telescopic rod 303 to drive multiple semipermeable membrane bodies 302 to move and adjust the relative position between each semipermeable membrane body 302 and the feed port according to the purification accuracy requirement information of the plant extract and the position information of each semipermeable membrane body 302, and control the discharge control valve 202 to adjust the plant delivery amount according to the characteristic data information of the semipermeable membrane and the delivery amount of the plant, and control the pressure structure 304 to adjust the internal pressure of the tank body 301 based on the characteristic data information of the semipermeable membrane and the delivery amount of the plant, so as to provide a force to penetrate the semipermeable membrane for the purification of the plant extract.

[0039] By using the purification device for plant extracts provided in the embodiment of the present disclosure, when purifying the plant extracts, based on the purification accuracy requirements for the plant extracts, by controlling the number of semi-permeable membrane bodies 302 used, the effective ingredients in the plant extracts can be efficiently separated, and impurities such as residues, pigments and pesticide residues in the plant extracts can be removed, thereby improving the purity of the plant extracts, ensuring the purification quality of the plant extracts while meeting the diversified purification requirements for the plant extracts. In addition, by using membrane filtration, there is no need to use multiple separation tanks, which reduces energy consumption and reduces purification costs. At the same time, during the purification process, strict control of the delivery volume and adjustment of the pressure can effectively ensure that the purification operation is carried out more stably and safely, and avoid the situation where the semi-permeable membrane body 302 is displaced, deformed or tilted under the action of force, which affects the purification operation, thereby ensuring the stability and safety of the purification operation.

[0040] Optionally, the feed port is opened in the middle of the tank body 301. In this way, the installation position of the feed port is more reasonable, ensuring that the fed material can accurately fall on the available semipermeable membrane body 302, reducing the influence of the remaining semipermeable membrane body 302 on the feeding process.

[0041] Optionally, the pressure structure 304 corresponds to the position of the feed inlet and is located on the upper side of the feed inlet. In this way, the influence of the unused semipermeable membrane 302 on the gas injection process of the pressure structure 304 is reduced, ensuring that the pressure adjustment can be carried out in an orderly manner, so that the plant extract can be filtered and purified more stably.

[0042] Optionally, there is a set distance between two adjacent semipermeable membrane bodies 302, and the set distance is greater than or equal to the distance between the pressure structure 304 and the feed inlet, and less than or equal to twice the distance between the pressure structure 304 and the feed inlet. In this way, the set distance is within a reasonable range, reducing the influence of unused semipermeable membrane bodies 302 on filtration and air pressure adjustment.

[0043] It can be understood that the pressure structure 304 is an electric cylinder or an air pump, which is used to inject air into the tank body 301 or discharge the air in the tank body 301 to adjust the air pressure in the tank body 301, and use the air pressure to provide a force to penetrate the semipermeable membrane for the purification of the plant extract. The electric cylinder and the air pump are both existing technologies, and the specific structure will not be repeated here.

[0044] Optionally, a delivery pump is provided at the position where the delivery pipeline 201 is connected to the pre-treatment structure 100, and the delivery pump provides power for the delivery of the plants. In this way, the material delivery can be completed efficiently and quickly.

[0045] like Figure 3-4As shown, optionally, the inner wall of the tank body 301 is evenly provided with the same number of clamping structures 600 as the semipermeable membrane body 302, and the clamping structure 600 is composed of a group of relatively movable annular clamping plates, which are used to clamp and fix the circumference of the semipermeable membrane body 302. In this way, the clamping mechanism 600 is used to clamp and fix the circumference of the semipermeable membrane body 302, so that the placement of the semipermeable membrane body 302 can be more stable, and the situation that the semipermeable membrane body 302 is displaced, deformed or tilted under the action of force, which affects the purification operation, ensures the stability of purification and the purification quality of the plant extract.

[0046] Optionally, a driving structure 601 is provided on the inner side wall of the tank body 301, and the driving structure 601 is connected to the clamping mechanism 600, and is used to drive the clamping structure 600 to clamp and fix the circumference of the semipermeable membrane body 302, wherein the driving structure 601 and the detection component 400 are both connected to the controller component 500, and the controller component 500 is used to control the driving structure 601 to drive the clamping mechanism 600 to clamp and fix the circumference of the semipermeable membrane body 302 according to the position information of the semipermeable membrane body 302 and when the semipermeable membrane body 302 enters the clamping structure 600. In this way, the control method is automated and intelligent, ensuring that the semipermeable membrane body 302 can be accurately clamped and fixed.

[0047] Optionally, the side of the annular clamping plate of the clamping structure 600 located on the upper side facing the top of the tank body 301 is an inclined surface, and the high end of the inclined surface corresponds to the side wall of the tank body 301. In this way, the plant extract can be effectively prevented from being left on the upper surface of the clamping structure 600, reducing the loss of the plant extract.

[0048] Optionally, each clamping structure 600 is independently controlled; preferably, each clamping structure 600 is equipped with a driving structure 601. In this way, by independently driving each clamping mechanism 600, the control method can be made more precise and stable, ensuring that each semi-permeable membrane 302 put into use is fixed, and avoiding the clamping mechanism 600 from being triggered by mistake.

[0049] It can be understood that the driving structure 601 is an electric slide rail 110, and the electric slide rail 110 is a prior art, and its specific structure is also not repeated here.

[0050] Optionally, each semipermeable membrane 302 is sealed to the clamping mechanism 600. In this way, the sealing between the semipermeable membrane 302 and the clamping structure 600 is enhanced to prevent the plant from leaking through the gap between the two, thereby ensuring the purification quality of the plant extract.

[0051] Optionally, a rubber sealing ring is provided on the inner side of the clamping mechanism 600. In this way, the rubber sealing ring has a simple structure, good sealing performance, and low cost.

[0052] like Figure 5-6 As shown, optionally, the pretreatment structure 100 includes a body 101, a crushing part 102 and an impurity removal part 103. The crushing part 102 is arranged in the body 101 and is used to crush the plants; the impurity removal part 103 is arranged in the body 101 and is located directly below the crushing part 102, and is used to treat the impurities of the crushed plants. In this way, by crushing the plants in the crushing part 102, it is convenient for subsequent better purification, and by removing impurities from the crushed plants, large particles of impurities in the plants can be effectively removed, thereby ensuring the purification quality of the plant extract.

[0053] Optionally, the crushing part 102 includes a crushing roller 108 and a driving motor 109. The crushing rollers 108 are arranged in pairs, and the driving motor 109 is connected to the crushing rollers 108 to drive the crushing rollers 108 to rotate. In this way, the driving method is simplified, the driving stability is ensured, and the plant crushing operation can be better performed.

[0054] Optionally, both ends of the pair of crushing rollers 108 are horizontally slidably connected to the side wall of the body 101. Preferably, both ends of the pair of crushing rollers 108 are connected to the side wall of the body 101 through an electric slide rail 110. The electric slide rail 110 is used to drive the pair of crushing rollers 108 to move closer to or farther from each other to adjust the distance between the pair of crushing rollers 108. In this way, by controlling the pair of crushing rollers 108 to slide horizontally to adjust the distance, the crushing size of the plant can be better controlled, so as to better remove impurities and extract effective components later.

[0055] Optionally, a conical discharge hopper is provided on the top of the machine body 101, and the conical discharge hopper corresponds to the symmetry axis of the paired crushing rollers 108. In this way, the plants can be accurately fed between the paired crushing rollers 108.

[0056] Optionally, the impurity removal section 103 includes a screening box 104 and a centrifuge box 105, the screening box 104 is connected to the bottom of the crushing section 102, and a filter 106 and an adsorbent sprayer 107 are arranged inside the screening box 104, and the adsorbent sprayer 107 is arranged on one side above the filter 106; the centrifuge box 105 is rotatably arranged at the bottom of the body 101, located at the lower side of the screening box 104. In this way, the particulate matter in the plant extract is removed by the filter 106, and the number of impurities in the subsequent processing steps is reduced. After the adsorbent is sprayed on the filter 106 by the adsorbent sprayer 107, chemical adsorption can remove residual impurities, such as organic acids, phenols and pigments, so that the extract is thoroughly impurity-removed. When the plant extract is filtered and enters the centrifuge box 105, the rotating centrifuge box 105 can remove chemical residues to ensure the quality of the plant extract.

[0057] Optionally, the detection component 400 is also used to detect the impurity components of the crushed plants, and the adsorbent sprayer 107 and the detection component 400 are both connected to the controller component 500. The controller component 500 is used to control the adsorbent sprayer 107 to spray the adsorbent onto the upper surface of the filter 106 according to the impurity components of the crushed plants. In this way, the impurity removal method is made intelligent, and efficient and thorough impurity removal operations can be performed according to impurity removal requirements.

[0058] Optionally, the centrifuge case 105 is a cylindrical structure, and a plurality of discharge holes are evenly provided on the side wall of the centrifuge case 105. In this way, the chemical adsorbent residue can be discharged from the centrifuge case 105 through the discharge holes under the action of the high-speed rotation of the centrifuge case 105.

[0059] Optionally, the bottom of the centrifuge case 105 is a conical structure, and one end of the delivery pipe 201 is connected to the bottom of the centrifuge case 105. In this way, the plant extract can be smoothly and thoroughly delivered to the tank body 301 through the delivery pipe 201.

[0060] It can be understood that the adsorbent is a chemical adsorbent, which is a prior art and will not be described in detail here.

[0061] Optionally, the plurality of semipermeable membrane bodies 302 have the same pore size. In this way, the plant extract can be thoroughly and efficiently filtered using the multi-layer semipermeable membrane body 302, thereby preventing useless substances from passing through the semipermeable membrane body 302, improving the thoroughness of purification, and ensuring the purification quality.

[0062] In other embodiments, the semipermeable membrane bodies 302 are optionally arranged in groups, and there are multiple groups, each group of semipermeable membrane bodies 302 includes multiple semipermeable membrane bodies 302 with different pore sizes, and the pore sizes of the semipermeable membrane bodies 302 in the same group increase from top to bottom. In this way, the effective ingredients in the plant extract are separated by the semipermeable membrane bodies 302 with multiple levels of different molecular weight cutoffs, and impurities such as proteins, polysaccharides, pigments, and harmful substances in the extract are removed, thereby ensuring the quality of the final plant extract.

[0063] like Figure 7 As shown, optionally, the purification device for plant extracts further includes: a collection container 700. The collection container 700 is connected to the bottom of the tank body 301, and the collection container 700 is a sealed container, on which a temperature and humidity regulator 701 is installed, and the temperature and humidity regulator 701 is used to adjust the temperature and humidity inside the collection container 700. In this way, after the plant extract is purified, it can be directly sent to the collection container 700 for storage without being transferred to other containers, which can effectively reduce the impact of the external environment on the quality of the plant extract and reduce costs.

[0064] Optionally, the outer surface of the collection container 700 is coated with a light-shielding material, so as to achieve the purpose of light-shielding storage, reduce the influence of light, and provide more favorable conditions for the storage of plant extracts.

[0065] Combination Figure 8 As shown, the embodiment of the present disclosure provides a control method for a purification device for plant extracts, which is used to control the purification device for plant extracts as described in any one of the above items, comprising:

[0066] S01, obtaining the purification accuracy requirement information of the plant extract and the position information of each semi-permeable membrane body;

[0067] S02, according to the purification accuracy requirement information of the plant extract and the position information of each semi-permeable membrane body, controlling the electric telescopic rod to drive the multiple semi-permeable membrane bodies to move and adjust the relative position between each semi-permeable membrane body and the feed port;

[0068] S03, obtaining characteristic data information of the semipermeable membrane;

[0069] S04, controlling the discharge control valve to adjust the delivery amount of the plant according to the characteristic data information of the semi-permeable membrane body;

[0070] S05, based on the characteristic data information of the semipermeable membrane and the delivery amount of the plant, the pressure structure is controlled to adjust the internal pressure of the tank to provide a force to penetrate the semipermeable membrane for the purification of the plant extract.

[0071] By adopting the control method for the purification device for plant extracts provided in the embodiment of the present disclosure, when purifying the plant extracts, based on the purification accuracy requirements for the plant extracts, by controlling the number of semipermeable membrane bodies used, the effective ingredients in the plant extracts can be efficiently separated, and impurities such as residues, pigments and pesticide residues in the plant extracts can be removed, thereby improving the purity of the plant extracts, ensuring the purification quality of the plant extracts while meeting the diversified purification requirements for the plant extracts. In addition, by adopting membrane filtration, there is no need to use multiple separation tanks, which reduces energy consumption and reduces purification costs. At the same time, during the purification process, strict control of the delivery volume and adjustment of the pressure can effectively ensure that the purification operation is carried out more stably and safely, and avoid the situation where the semipermeable membrane body is displaced, deformed or tilted under the action of force, which affects the purification operation, thereby ensuring the stability and safety of the purification operation.

[0072] Optionally, the purification accuracy requirement information includes first purification accuracy requirement information, second purification accuracy requirement information, and third purification accuracy requirement information, wherein the first purification accuracy requirement information is that the impurity content of the plant extract is less than or equal to 3%; the second purification accuracy requirement information is that the impurity content of the plant extract is greater than 3% and less than 6%; the third purification accuracy requirement information is that the impurity content of the plant extract is greater than or equal to 6%. In this way, the purification accuracy is divided into three levels, which is convenient for more accurately controlling the number of semipermeable membranes used according to the purification accuracy requirements, so that the semipermeable membrane can be used to better filter and purify the plant extract.

[0073] Optionally, the characteristic data information of the semipermeable membrane body includes the bearing capacity of the semipermeable membrane body, wherein the bearing capacity of the semipermeable membrane body is greater than or equal to 0.7 kgf / cm 2 , and less than or equal to 10kgf / cm 2 In this way, by determining the bearing capacity of the semipermeable membrane, it is convenient to control the pressure more accurately in the future, ensuring that the plant extract can stably and smoothly pass through the semipermeable membrane while avoiding deformation or displacement of the semipermeable membrane.

[0074] Optionally, according to the purification accuracy requirement information of the plant extract and the position information of each semipermeable membrane body, after controlling the electric telescopic rod to drive multiple semipermeable membrane bodies to move and adjust the relative position between each semipermeable membrane body and the feed port, it also includes: based on the position information of the semipermeable membrane body, and when the semipermeable membrane body enters the clamping structure, controlling the driving structure to drive the clamping mechanism to clamp and fix the circumference of the semipermeable membrane body. In this way, the clamping mechanism is used to clamp and fix the circumference of the semipermeable membrane body, which can make the placement of the semipermeable membrane body more stable, avoid the situation where the semipermeable membrane body is displaced, deformed or tilted under the action of force, which affects the purification operation, and ensure the stability of purification and the purification quality of the plant extract.

[0075] Optionally, before obtaining the purification accuracy requirement information of the plant extract and the position information of each semi-permeable membrane body, the method includes: controlling the driving motor to drive the crushing roller to rotate to crush the plant. In this way, by crushing the plant, it is convenient for subsequent better purification, and by removing impurities from the crushed plant, large particles of impurities in the plant can be effectively removed, thereby ensuring the purification quality of the plant extract.

[0076] Optionally, before controlling the driving motor to drive the crushing rollers to rotate and crush the plants, the method includes: obtaining the crushing size requirement information of the plants; and controlling the pair of crushing rollers to slide horizontally to adjust the spacing according to the crushing size requirement information of the plants. In this way, by controlling the pair of crushing rollers to slide horizontally to adjust the spacing, the crushing size of the plants can be better controlled, so as to better remove impurities and extract effective components later.

[0077] Optionally, according to the information on the crushing size requirement of the plants, controlling the pair of crushing rollers to slide horizontally to adjust the spacing includes: based on the information on the crushing size requirement of the plants, controlling the pair of crushing rollers to slide closer or farther to adjust the spacing between the two rollers.
