Description

Technical Field

[0001] This invention relates to the field of extraction equipment, specifically to a functional component extraction device. Background Technology

[0002] Chrysanthemums and other agricultural products are rich in flavonoids, amino acids and other functional components with pharmacological value, and have wide applications in the fields of medicine, health care and food.

[0003] Traditional extraction methods such as decoction and soaking have drawbacks such as low extraction efficiency, high energy consumption, and easy loss of active ingredients. Ultrasonic extraction technology, utilizing its cavitation effect and mechanical vibration, can efficiently accelerate the release and diffusion of active ingredients within plant cells while maintaining their biological activity, and has therefore attracted widespread attention.

[0004] However, in existing ultrasonic extraction methods, the solvent and agricultural products are fed into the extraction equipment together before ultrasonic extraction. However, after extraction, there are problems such as difficulty in solid-liquid separation and large amounts of solvent residue in the extracted material. This not only increases the burden on subsequent processing steps, but also leads to solvent waste and loss of target components, ultimately restricting the working efficiency of the equipment and the utilization rate of agricultural products. Summary of the Invention

[0005] The purpose of this invention is to address the above problems by providing a functional component extraction device that can improve the working efficiency of ultrasonic extraction equipment and the utilization rate of agricultural products.

[0006] To achieve the above objectives, the technical solution adopted by this invention is as follows: a functional component extraction device, comprising a shell, a liquid addition pipe at the upper part of the shell, a liquid discharge pipe at the lower end of the shell, and an ultrasonic generator mounted on the shell; a storage cylinder is vertically arranged inside the shell, the storage cylinder is hollow, and through holes are spaced apart on the side wall of the storage cylinder; a feeding port leading to the inner cavity of the storage cylinder is provided on the shell; the storage cylinder is rotatably mounted inside the shell, and stirring blades are provided on its outer side wall. The stirring action generated by the rotation of the storage cylinder driving the stirring blades, combined with the ultrasonic waves generated by the ultrasonic generator, accelerates the diffusion of functional components from plant cells to the solvent, thereby significantly improving the extraction efficiency and extraction rate. After extraction, the solvent flows out through the liquid discharge pipe, while the solid material is effectively retained inside the storage cylinder. This achieves solid-liquid separation, improving the working efficiency of the ultrasonic extraction equipment and the utilization rate of agricultural products.

[0007] Furthermore, to improve extraction efficiency, an agitator is provided on the inner wall of the storage cylinder; a vertical section is also fixedly installed inside the housing, with protrusions spaced apart on the outer wall of the vertical section. When the storage cylinder rotates, the agitator inside the storage cylinder moves relative to the fixed vertical section and its protrusions, thereby compressing the material and increasing the dissolution rate of the functional components, thus improving extraction efficiency. Simultaneously, it fully agitates the material inside the storage cylinder, ensuring sufficient contact between the material and the solvent, thereby improving material utilization.

[0008] Furthermore, to further improve work efficiency, a collection pipe is arranged laterally inside the housing. The lower end of the storage cylinder is connected to the top wall of the collection pipe via a bearing to achieve stable rotation and reliable sealing of the storage cylinder. The material between the storage cylinder and the vertical part enters the collection pipe through a material hole. One end of the collection pipe is connected to a discharge hole on the side wall of the housing. After extraction is completed, the material hole opens, allowing the material between the storage cylinder and the vertical part to fall into the collection pipe. This eliminates the need for manual material removal by opening the device; the material automatically enters the collection pipe under gravity through the material hole. Simultaneously, the bottom wall of the collection pipe is inclined downwards on the side of the discharge hole to facilitate the movement of agricultural products towards the discharge hole, further simplifying material collection and improving work efficiency.

[0009] Furthermore, a transverse screw is provided inside the collection pipe, which is aligned with the bottom wall. The transverse screw is located at the lower part of the inner side of the collection pipe and is connected to the conveying motor. Driven by the motor, the transverse screw rotates, thereby actively and directionally moving the material inside the collection pipe toward the discharge hole.

[0010] Furthermore, to facilitate the installation of the transverse screw and conveyor motor while preventing the motor housing from contacting the agricultural products, a baffle is installed along the cross-section of the collection pipe. The transverse screw and the motor housing are positioned on opposite sides of the baffle, with the transverse screw located on one side of the discharge hole. The baffle prevents the agricultural products from contacting the conveyor motor, thus avoiding corrosion and reducing the failure rate.

[0011] Furthermore, a guide plate is inclinedly arranged on the partition above the transverse screw, with its lower side extending towards the discharge hole. The guide plate guides the agricultural products away from the connection area between the transverse screw and the output shaft of the conveyor motor.

[0012] Furthermore, the top wall of the collecting pipe is equipped with a suction port and a spray port, wherein the suction port is located outside the storage cylinder, and the spray port is located between the storage cylinder and the vertical section. The suction port and the spray port are respectively connected to a first water pump via pipes. A cooling pipe is installed inside the shell, and a second water pump is installed on the top wall of the shell. The suction end and outlet end of the second water pump are connected to the suction pipe and the outlet pipe, respectively. The outlet of the outlet pipe is located outside the storage cylinder, and the inlet of the suction pipe is located between the storage cylinder and the vertical section. The internal circulation loop driven by the first water pump pumps the solvent outside the storage cylinder to the area between the storage cylinder and the vertical section, forming a directional jet, which agitates and washes the material in this area a second time. This effectively prevents material accumulation and forces the solvent to penetrate the material layer at high speed, thereby greatly enhancing the diffusion rate of the active ingredients and significantly shortening the extraction time. Pump No. 2 returns the liquid from the core area to the outside of the storage tank, working in conjunction with Pump No. 1 to create a strong three-dimensional circulation within the casing. This ensures sufficient and uniform contact between the material and the solvent, fundamentally guaranteeing consistent extraction and high yield. Simultaneously, the system uses cooling pipes to promptly remove excess heat generated by the reaction, ensuring the entire extraction process operates within the predetermined optimal temperature range and guaranteeing the quality of the final product.

[0013] Furthermore, to further agitate the material between the storage cylinder and the vertical section, nozzles are provided on the side wall of the vertical section. These nozzles are connected to one end of a flow channel, and the other end of the flow channel is connected to the outlet of a water pump. This multi-point, multi-directional water jet from the side wall of the vertical section ensures proper agitation of the material between the storage cylinder and the vertical section, allowing all material particles to be extracted evenly and thoroughly, thus guaranteeing the quality of the final product.

[0014] Furthermore, an openable channel is provided on the lower part of the vertical section's sidewall, with the material hole communicating with the inner cavity of the vertical section. A pusher plate is provided on the inner sidewall of the storage cylinder. When extraction is completed and the discharge stage begins, the channel at the lower part of the vertical section opens. At this time, the storage cylinder is driven to rotate, and the pusher plate on its inner sidewall moves accordingly, thereby pushing the material towards and through the channel into the inner cavity of the vertical section. Under the influence of gravity and the push of subsequent materials, the material entering the vertical section eventually falls into the collection pipe through the opened material hole at the lower part and is discharged from the device through the collection pipe.

[0015] Furthermore, a baffle is provided on the inner wall of the shell, and a protrusion is provided on the outer wall of the storage cylinder. A support is provided on the baffle, and a striking part is provided on the support that can automatically reset after separating from the protrusion. The baffle disrupts the regular flow of the liquid, increases turbulence, prevents material deposition, and promotes the passage of fine particles through the screen. Simultaneously, when the storage cylinder rotates, the protrusion on its outer side periodically impacts the striking part, which in turn strikes the side wall of the storage cylinder. This effectively dislodges particles adhering to or blocking the through-holes of the storage cylinder, preventing blockage and material caking.

[0016] The beneficial effects of this invention are as follows: The solvent is added to the shell, while the agricultural product is added to the storage cylinder. After extraction, most of the remaining agricultural product remains in the storage cylinder, preventing it from being discharged from the shell with the extract. This rapid separation of agricultural product and extract improves work efficiency and agricultural product utilization. Simultaneously, after the extract is discharged from the shell, the storage cylinder rotates, using centrifugal force to eject the extract from the storage cylinder, further enhancing agricultural product utilization.

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0028] Example 1, as Figure 1 As shown, the specific structure of the present invention is a functional component extraction device, including a housing 1. The upper part of the housing 1 is provided with a liquid injection pipe 2 for injecting extraction solvent, and the lower end is provided with a liquid discharge pipe 3 for discharging the extracted solvent. An ultrasonic generator 4 is installed on the housing 1, and the ultrasonic generator 4 is used to emit ultrasonic waves into the housing 1.

[0029] A storage cylinder 5 is vertically arranged inside the shell 1. In this embodiment, the storage cylinder 5 is coaxially arranged with the shell 1. The upper end of the storage cylinder 5 is rotatably installed inside the shell 1 through bearings or the like. A stirring motor transmission mechanism (such as a belt, gear, or other transmission mechanism) is provided outside the shell 1 to drive the storage cylinder 5 to rotate. The storage cylinder 5 is hollow inside to accommodate the agricultural raw materials to be extracted. Multiple through holes 6 are spaced apart on its side wall to allow solvent to pass freely while trapping solid materials. A feeding port 7 is provided on the shell 1 to lead to the inner cavity of the storage cylinder 5. The outer side wall of the storage cylinder 5 is solid A stirring blade 8 is fixedly provided. When the storage cylinder 5 rotates, the stirring blade 8 stirs the solvent between the shell 1 and the storage cylinder 5. To further enhance the extraction effect, an agitator 9 is provided on the inner wall of the storage cylinder 5. In this embodiment, the agitator 9 consists of multiple strip-shaped protrusions welded to the inner wall. Simultaneously, a vertical section 101 is fixedly provided on the lower surface of the top wall of the shell 1. The upper end of the vertical section 101 is closed, and the vertical section 101 is coaxially arranged with the shell 1. Protrusions 102 are spaced apart on the outer wall of the vertical section 101. The protrusions 102 can be hemispherical or similar.

[0030] Multiple baffles 18 are fixedly installed on the inner wall of the housing 1 by welding or other means. The baffles 18 are arranged radially along the housing 1, and the positions of the baffles 18 and the stirring blades 8 are staggered. A protrusion 19 is provided on the outer wall of the storage cylinder 5. The cross-section of the protrusion 19 is an arc. A support 20 is provided on the baffle 18. The support 20 moves laterally. For this purpose, a linear output mechanism such as an electric push rod and a cylinder is provided inside the baffle 18. A shaft seal is provided at the connection between the piston rod of the linear output mechanism and the baffle. The piston rod of the linear output mechanism extends out of the baffle 18 and connects to the support 20. The support 20 is connected to the striking part 21 on one side of the storage cylinder 5 by a torsion spring or other means, so that the striking part 21 can automatically reset after separating from the protrusion 19.

[0031] The specific working process is as follows: Chrysanthemum and other agricultural raw materials are fed into the storage cylinder 5 through the feeding port 7, and an appropriate amount of extraction solvent is injected into the shell 1 through the liquid addition pipe 2. Then, the ultrasonic generator 4 and the stirring motor 22 are started. The stirring motor 22 drives the storage cylinder 5 to rotate at a uniform speed to carry out the extraction operation.

[0032] During the rotation of the storage cylinder 5, the protrusion 19 on the outer wall of the storage cylinder 5 periodically impacts the striking part 21 on the baffle 18. As the striking part 21 rotates, it periodically strikes the outer wall of the storage cylinder 5, thereby causing the side wall of the storage cylinder 5 to vibrate, effectively dislodging small materials that are attached to or blocked in the through hole 6, and keeping the through hole 6 unobstructed.

[0033] After extraction, the device is left to stand. The drain pipe 3 is opened, and the extract rich in active ingredients flows out through the through-hole 6 and is eventually collected from the drain pipe 3. Solid residue is retained in the storage cylinder 5. After the storage cylinder 5 stops rotating, the remaining agricultural products in the storage cylinder 5 are removed by opening the feed port 7.

[0034] Example 2, as Figures 3-5 As shown, the other structures and working processes of this embodiment are the same as those of Embodiment 1. However, in this embodiment, a collection pipe 10 is arranged horizontally inside the housing 1. The two ends of the collection pipe 10 are fixedly connected to the left and right side walls of the housing 1, respectively. The lower end of the storage cylinder 5 is connected to the top wall of the collection pipe 10 through a bearing to achieve stable rotation and bottom sealing of the storage cylinder 5. The lower end of the vertical part 101 is fixedly connected to the upper surface of the collection pipe. An openable channel 112 is provided at the lower part of the side wall of the vertical part 101. A pusher plate 17 is provided on the inner side wall of the storage cylinder 5. A material hole 11 is opened on the top wall of the collection pipe 10. The material hole 11 communicates with the inner cavity of the vertical part 101, so that the material located between the storage cylinder 5 and the vertical part 101 can enter the collection pipe 10 when the channel 112 is opened. One end of the collection pipe 10 is connected to the discharge hole 12 on the side wall of the housing 1.

[0035] The top wall of the collecting pipe is provided with a suction port 103 and a spray port 104. The suction port 103 is located outside the storage cylinder 5 and is used to draw liquid between the storage cylinder 5 and the side wall of the shell 1. The spray port 104 is located between the storage cylinder 5 and the vertical part 101 and is used to spray liquid into the space between the storage cylinder 5 and the vertical part 101. A nozzle is provided at the spray port 104. The spray ports 104 can be arranged in a ring array around the axis of the shell 1. The suction port 103 and the spray port 104 are respectively connected to pipes. It is connected to the No. 1 water pump 105; a cooling pipe 106 is provided inside the housing 1, and the inlet and outlet of the cooling pipe 106 extend to the outside of the housing for connection to an external cooling medium circulation system. A No. 2 water pump 107 is provided on the top wall of the housing 1. The suction end and the outlet end of the No. 2 water pump 107 are connected to the suction pipe 108 and the outlet pipe 109, respectively. The outlet of the outlet pipe 109 is located outside the storage cylinder 5, and the inlet of the suction pipe 108 is located between the storage cylinder 5 and the vertical part 101.

[0036] A nozzle 110 is provided on the side wall of the vertical part 101. The nozzle 110 is connected to one end of the flow channel 111, and the other end of the flow channel 111 is connected to the outlet of the No. 1 water pump 105.

[0037] The specific working process is as follows: Pump 105 pumps the solvent from the outside of the storage cylinder 5 into the storage cylinder 5. One stream is delivered to the spray nozzle 104 on the top wall of the collection pipe, and the other stream is ejected from the nozzle 110 of the vertical part 101 through the flow channel 111. The two jets work together to scour and agitate the material between the storage cylinder 5 and the vertical part 101.

[0038] The second water pump 107 extracts the solvent from the area between the storage cylinder 5 and the vertical section 101 and sprays it into the space outside the storage cylinder 5. This allows the solvent to flow freely, thereby promoting mixing. At the same time, the circulating solvent is cooled as it passes over the surface of the cooling pipe 106, thereby stabilizing the extraction temperature within the optimal range.

[0039] After extraction, the extract is first discharged through the drain pipe 3. Then, the channel 112 at the bottom of the vertical section 101 is opened. As the storage cylinder 5 rotates, the pusher plate 17 on the inner wall of the storage cylinder 5 moves accordingly, continuously pushing the material deposited at the bottom of the storage cylinder 5 upwards and into the vertical section 101 through the opened channel 112. The material falls into the cavity of the vertical section 101 by gravity and enters the collection pipe 10 below through the material hole 11. Finally, the material is collected in the collection pipe 10 and discharged from the device through the discharge hole 12, completing the entire process of solid-liquid separation and residue cleaning.

[0040] Example 3, as Figures 6-9As shown, the other structures and working processes of this embodiment are the same as those of Embodiment 2. However, in this embodiment, the lower part of the collecting tube 10 is tapered inward and its bottom wall is arc-shaped. A transverse screw 13 is provided inside the collecting tube 10, which is in the same direction as its bottom wall. The transverse screw 13 is located in the lower part of the inner side of the collecting tube 10. The rotation path of the external thread on the transverse screw 13 is adapted to the bottom wall of the collecting tube 10. One end of the transverse screw 13 is connected to the output shaft of the conveying motor 14 fixedly installed in the collecting tube 10 through a coupling, so that the conveying motor 14 can drive the transverse screw 13 to rotate.

[0041] A partition 15 is provided inside the collection pipe 10 along its cross-section. The partition 15 divides the inner cavity of the collection pipe 10 into two independent chambers. The housings of the transverse screw 13 and the conveying motor 14 are placed on both sides of the partition 15. The transverse screw 13 is located on one side of the discharge hole 12, while the housing of the conveying motor 14 is sealed in the other chamber, so that it does not come into contact with the material.

[0042] A guide plate 16 is inclinedly arranged on the partition plate 15 above the transverse screw 13, and the guide plate 16 extends to the lower side of the discharge hole 12.

[0043] Specific extraction process: After extraction is completed and the material hole 11 is opened, the material in the storage cylinder 5 moves to the middle section of the transverse screw 13 via the guide plate 16, so that the agricultural products are pushed to the discharge hole 12 by the transverse screw 13.
