Description

Technical Field

[0001] This invention relates to the field of artemisia extraction technology, and in particular to an artemisia essential oil extraction device. Background Technology

[0002] Currently, the mainstream extraction method for Artemisia argyi essential oil in industrial production is steam distillation. This process, with its advantages of simple operation, controllable cost, and suitability for large-scale production, has become the core technology for Artemisia argyi essential oil extraction. However, in the actual production application of existing conventional Artemisia argyi essential oil distillation extraction equipment, many technical defects are prevalent, severely restricting the extraction efficiency and purity of Artemisia argyi essential oil, resulting in a large waste of raw materials and hindering large-scale, refined production. Artemisia argyi raw material is light and fibrous, and when large quantities are added to distillation equipment, it is prone to accumulation and clumping. Dense stacking of raw materials leads to poor steam circulation inside the equipment, preventing steam from fully contacting the Artemisia argyi leaves and stems. Deeply accumulated raw materials are difficult to effectively distill and extract, directly causing insufficient extraction of essential oil and low oil yield, significantly reducing raw material utilization.

[0003] Among them, Chinese patent application CN201810579877.9 discloses a distillation extraction device for Artemisia argyi essential oil, including a distillation tank body. A carrying tank is provided at the top of the distillation tank body. Several fixing rods are provided on both sides of the carrying tank, and the other side of each fixing rod is fixedly connected to the inner wall of the distillation tank body. A stirring structure is provided inside the carrying tank. The top of the stirring structure is connected to a drive motor located at the top of the distillation tank body. A feed pipe is provided through one side of the top of the carrying tank. The top of the feed pipe passes through the top of the distillation tank body and is connected to a feed hopper located at the top of the distillation tank body.

[0004] Secondly, the stirring structure design of the aforementioned device is flawed and poorly adapted to specific applications. Due to the fine, soft, and easily sticky nature of mugwort raw materials, conventional stirring structures cannot achieve uniform stirring throughout the entire equipment. This not only makes it difficult to break up clumps of raw materials and ensures even heating and steam distribution, but also easily leads to material adhering to the inner walls of the equipment and the surfaces of the stirring components. Adhered mugwort raw materials cannot participate in the distillation reaction, resulting in material residue and waste. Long-term adhesion and accumulation can also breed impurities, affecting equipment cleanliness and frequently causing inconsistent quality of essential oils produced in batches.

[0005] Meanwhile, the existing equipment has an unreasonable feeding structure design. After the distillation operation is completed, the clumped and sticky Artemisia argyi residue is very easy to get stuck inside the equipment, resulting in problems with poor feeding and incomplete discharge. Manual assistance is required for cleaning, which not only increases the cost of manual operation and production time, but also reduces the overall production efficiency and affects the continuity of production and the stability of product quality. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of raw material accumulation and clumping, inconvenience of stirring and feeding in existing artemisia essential oil extraction equipment, which leads to insufficient distillation and extraction of artemisia and low utilization rate of raw materials.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Reference Figures 1-9 A device for extracting Artemisia argyi essential oil includes a tank 2. A frame 1 is located on the outer side of the middle section of the tank 2, providing stable support and fixing for the entire device, ensuring overall stability during operation. A steam box 8 is located at the bottom of the tank 2, serving as the core structure for distillation heat and steam supply, providing continuous and stable high-temperature steam for the distillation operation inside the tank 2. A feeding cover 7 is located on one side of the top of the tank 2. Operators can add Artemisia argyi raw materials into the tank 2 by opening the feeding cover 7 and closing the cover 7 after feeding to ensure the airtightness of the tank 2 during distillation, preventing steam leakage and ensuring the distillation extraction effect. A filter plate 13 is located inside the tank 2, with evenly distributed perforated pores. The high-temperature steam generated by the steam box 8 can penetrate upwards through the filter plate 13 and diffuse evenly into the raw material chamber of the tank 2, fully contacting the Artemisia argyi raw materials placed above the filter plate 13, thereby achieving steam distillation extraction of the Artemisia argyi stems and leaves, effectively separating the essential oil components inside the Artemisia argyi. A hydraulic telescopic rod 14 is located at the top of the filter plate 13, which can... The hydraulic telescopic rod 14 moves vertically and reciprocally within the tank 2, providing power support for material shaking, feeding, wall scraping, and unloading operations. Two support boxes 15 are located at the bottom of the hydraulic telescopic rod 14, with their tops fixedly connected to the bottom. The two support boxes 15 are symmetrically arranged about the hydraulic telescopic rod 14 as an axis of symmetry. The tops of the support boxes 15 are firmly fixed to the bottom of the hydraulic telescopic rod 14, ensuring the synchronous movement stability of the overall structure. Feeding plates 17 are provided on the outer sides of each support box 15, and the feeding plates 17 are semi-circular in shape. The material is designed in an arc shape, and the maximum outer diameter of the material feeding plate 17 is smaller than the inner diameter of the tank body 2, so that the material feeding plate 17 can be raised, lowered and rotated without interference inside the tank body 2, avoiding movement jamming and structural wear. A scraper 18 is provided on the outer side of the material feeding plate 17. A soft scraper 18 is integrally fitted on the outer edge of the material feeding plate 17. The scraper 18 is made of high temperature resistant and wear-resistant soft material, which can flexibly conform to the inner wall of the tank body 2 without scratching the inner wall of the tank body 2. A discharge port 25 is provided on one side of the bottom of the tank body 2, and a discharge channel 27 is provided on the outer side of the discharge port 25.

[0035] During the distillation process, the hydraulic telescopic rod 14 drives the two sets of material-pulling plates 17 to simultaneously complete the lifting and angle adjustment actions. When the hydraulic telescopic rod 14 drives the material-pulling plates 17 downward, the two sets of material-pulling plates 17 simultaneously tilt inward and retract, forming an arrow-shaped cone structure. This allows them to smoothly penetrate and pierce into the compacted layer of Artemisia argyi material, avoiding material accumulation and obstruction during the downward pressing process. At the same time, they can break up the clumps and stacks of Artemisia argyi material layer by layer. Subsequently, the hydraulic telescopic rod 14 drives the material-pulling plates 17 to rise upward. During the rise, the two sets of material-pulling plates 17 gradually flip and unfold outward, continuously shaking, turning, and loosening the Artemisia argyi material inside the tank 2. This effectively breaks up the loose, compacted, and clump-like state of the Artemisia argyi raw material, eliminating the problem of dense and impermeable material layers. This allows high-temperature steam to evenly penetrate each layer of Artemisia argyi material, significantly increasing the contact area between the material and the steam. This ensures that the essential oil components in the stems and leaves of Artemisia argyi can be fully distilled and extracted, effectively solving the defects of insufficient distillation and low oil yield in traditional equipment.

[0036] When the distillation operation is completed and waste residue needs to be discharged, the support box 15 drives the two sets of material-pulling plates 17 to rotate and adjust to a horizontally extended state, so that the soft scraper 18 on the outside of the material-pulling plate 17 completely adheres to the side wall of the tank body 2. Then, the hydraulic telescopic rod 14 drives the entire structure to move downward at a uniform speed. On the one hand, the scraper 18 thoroughly scrapes and cleans the inner wall of the tank body 2, completely removing the residual material of Artemisia argyi adhering to the inner wall of the tank body 2, fundamentally solving the problem of raw material sticking to the wall and wasting raw materials; on the other hand, the horizontal material-pulling plate 17 squeezes and pushes the material downward, accelerating the falling and discharge of waste residue in the tank body 2.

[0037] During the feeding process, the material guide plate 17 on the side furthest from the discharge port 25 can be selectively controlled to deflect and rotate in one direction. Through the directional rotational thrust of the material guide plate 17, the residual material inside the tank 2 is continuously pushed and squeezed towards the discharge port 25, effectively solving the problems of feeding jams, material retention, and incomplete discharge in traditional devices, and achieving fast and thorough automated feeding. The tank 2 has a discharge port 25 on one side of its bottom, and an inclined feeding channel 27 is connected to the outside of the discharge port 25. After being scraped and pushed, the Artemisia argyi waste residue can be quickly introduced into the feeding channel 27 through the discharge port 25 to complete automatic discharge. No manual cleaning is required, which greatly reduces the intensity of manual labor and improves the continuous production efficiency of the equipment.

[0038] A reducer 3 is installed on the top of the tank body 2. The bottom of the reducer 3 is fixedly connected to the tank body 2, and the connection contact surface is flat and fits snugly to ensure installation stability and sealing. It can effectively offset the vibration generated during equipment operation and avoid structural loosening or displacement during long-term operation. A first motor 4 is installed on the top of the reducer 3. The bottom of the first motor 4 is connected to the reducer 3 by bolts. The bottom of the reducer 3 is connected to the top of the hydraulic telescopic rod 14. The first motor 4 serves as a rotation drive source and can output stable rotational power. The power is adjusted and amplified by the reducer 3, converting the high-speed, low-torque power of the motor into low-speed, high-torque driving power. Through the cooperative drive structure of the first motor 4 and the reducer 3, the rotation angle, swing amplitude and rotation rhythm of the hydraulic telescopic rod 14 and the two sets of material-pulling plates 17 at the bottom can be precisely controlled. In conjunction with the vertical lifting and lowering action of the hydraulic telescopic rod 14, the lifting and lowering movement of the material-pulling plates 17 and the rotational material-pulling action are coordinated.

[0039] A pipe 5 is connected to the top side of the tank 2. The essential oil-containing mixed vapor generated by high-temperature distillation inside the tank 2 can be smoothly discharged through the steam inlet pipe 5. A condenser box 6 is provided at the bottom of the pipe 5. A support 9 is provided at the bottom of the condenser box 6. The support 9 can provide stable load-bearing support for the condenser box 6. A valve 10 is provided on the outside of the bottom of the condenser box 6. The high-temperature essential oil mixed vapor is rapidly cooled and condensed, so that the gaseous mugwort essential oil vapor is quickly cooled and liquefied, and it gathers together with water vapor at the bottom of the condenser box 6, realizing the effective enrichment and collection of mugwort essential oil. After condensation, the mugwort essential oil liquid and condensate mixture collected in layers inside the condenser box 6 can be discharged in a directional manner by opening the valve 10, which facilitates subsequent static stratification and purification processing.

[0040] A third connecting pipe 33 is connected to the outside of the steam box 8, which can continuously provide water to the steam box 8. A second connecting pipe 32 is connected to the top of the steam box 8, and a first connecting pipe 31 is bolted to the top of the second connecting pipe 32. The top of the first connecting pipe 31 is connected to the bottom of the tank body 2. The steam inside the steam box 8 enters the tank body 2 through the first connecting pipe 31 and the second connecting pipe 32.

[0041] Each support box 15 is equipped with a second motor 19. The bottom of the second motor 19 is fixedly connected to the support box 15. A first gear 20 is provided on the outside of the second motor 19. A second gear 21 meshes with the bottom of the first gear 20. A worm gear 22 is fixedly connected to the outside of the second gear 21. The outside of the worm gear 22 is rotatably connected to the support box 15. A worm wheel 23 meshes with the top of the worm gear 22. A rotating shaft 16 is fixedly connected inside the worm wheel 23. The middle part of the rotating shaft 16 is rotatably connected to the support box 15. The outside of the rotating shaft 16 is fixedly connected to the corresponding feeding plate 17. The rotation of the second motor 19 can drive the first gear 20 to rotate, and through gear meshing transmission, it drives the second gear 21 and the worm gear 22 to rotate. The mechanism rotates in one step, and then uses the worm gear 23 and worm shaft 22 to achieve power reversal and torque amplification, thereby driving the worm gear 23 and the rotating shaft 16 to rotate synchronously. The forward and reverse rotation of the rotating shaft 16 is used to precisely control the tilt angle of the material feeding plate 17. The worm gear 23 and worm shaft 22 mechanism has a self-locking characteristic. After the second motor 19 stops, the current posture of the material feeding plate 17 can be locked. There is no need to continuously power on to maintain the angle. It can stably maintain the material feeding plate 17 in various working states such as closing and moving downward in an arrow shape, flipping and shaking upward, and horizontally unfolding and scraping the wall. It can also independently control the deflection amplitude of the left and right material feeding plates 17. During the material feeding stage, the material feeding plate 17 on the side away from the discharge port 25 is driven to rotate unidirectionally to push the material.

[0042] A baffle 12 is slidably connected inside the discharge port 25. The inner side of the baffle 12 abuts against the outer wall of the tank body 2. An electric push rod 11 is provided on the top of the baffle 12. The telescopic part of the electric push rod 11 is fixedly connected to the baffle 12, and the fixed part of the electric push rod 11 is fixedly connected to the tank body 2. The extension and retraction of the electric push rod 11 can drive the baffle 12 to move up and down, thereby completing the opening and closing of the discharge port.

[0043] A feeding motor 24 is bolted to one side of the discharge port 25. The feeding motor 24 is externally mounted. A cross fork 26 is connected to the inner side of the feeding motor 24. The feeding motor 24 drives the cross fork 26 to rotate in a circular motion. The cross fork 26 and the discharge port 25 are rotatably connected. A first connecting rod 28 is fixedly connected to the other side of the cross fork 26. The first connecting rod 28 can rotate synchronously with the cross fork 26. The inner side of the first connecting rod 28 is rotatably connected to the discharge port 25. A second connecting rod 29 is hinged to the top of the first connecting rod 28. The first connecting rod 28 drives the reciprocating displacement of the hinged second connecting rod 29. A feeding fork 30 is fixedly connected to the outer side of the second connecting rod 29. A groove 34 is provided on one side of the feeding channel 27. The outer side of the fork passes through the groove 34 and is slidably connected to the groove 34. The feeding fork 30 can slide and deflect along the trajectory of the groove 34.

[0044] During operation, the cross fork 26 rotates continuously, driving the first connecting rod 28 to rotate synchronously, which in turn pulls the second connecting rod 29 to perform regular reciprocating oscillations. Ultimately, this drives the feeding fork 30 to slide up and down along the slide groove 34, and in conjunction with the connecting rod hinge, achieves synchronous angle flipping. When the feeding fork 30 slides down along the slide groove 34, the second connecting rod 29 simultaneously presses down and swings, driving the feeding fork 30 to flip down and tilt forward, actively pressing down and pushing the Artemisia argyi waste residue in the feeding channel 27, further breaking up the material accumulation and blockage in the channel, and accelerating the waste residue to slide out. When the feeding fork 30 slides back up with the second connecting rod 29, the second connecting rod 29 swings in the opposite direction, driving the feeding fork 30 to flip up and lift, so that the feeding fork 30 avoids the material falling channel as a whole, reducing the upward resistance, preventing the return stroke from carrying material and jamming the channel, and ensuring smooth and cyclical feeding action.

[0045] In this invention, when the Artemisia argyi essential oil extraction device is working, the top feeding cover 7 of the tank 2 is first opened to add Artemisia argyi stems and leaves. After feeding, the feeding cover 7 is closed to ensure the tank 2 is sealed. The steam box 8 is continuously replenished with water through the third connecting pipe 33, which heats and generates high-temperature steam. The steam flows sequentially through the second connecting pipe 32 and the first connecting pipe 31 and is conveyed upwards, evenly penetrating the filter plate 13 inside the tank and making full contact with the Artemisia argyi material above the filter plate 13 to carry out steam distillation extraction. During the distillation stage, the first motor 4 at the top of the tank 2, in conjunction with the reducer 3, outputs high torque rotational power, driving the hydraulic telescopic rod 1. 4. Overall rotation: The second motor 19 inside the support box 15 drives the rotating shaft 16 to rotate through the transmission pairs of the first gear 20, the second gear 21, the worm 22, and the worm wheel 23, thereby adjusting the tilt angle of the two material-pulling plates 17. When the hydraulic telescopic rod 14 drives the material-pulling plates 17 downward, the two material-pulling plates 17 retract inward into an arrow cone shape, piercing and breaking the hardened and accumulated mugwort material layer. During the upward movement of the hydraulic telescopic rod 14, the material-pulling plates 17 flip outward and unfold, repeatedly shaking and dispersing the material, eliminating the problem of the raw material being dense and impermeable to steam, allowing steam to fully contact the mugwort, and increasing the amount of essential oil extracted.

[0046] The essential oil-containing vapor produced by distillation is sent into the condenser 6 through the top pipe 5 of the tank 2. The high-temperature vapor is rapidly cooled and liquefied in the condenser 6. The mugwort essential oil and condensate water gather at the bottom of the condenser 6. After the operation is completed, the valve 10 at the bottom of the condenser 6 is opened to discharge the oil-water mixture, which facilitates the subsequent stratification and collection of essential oil.

[0047] After the distillation process is completed, the automatic feeding stage begins. The electric push rod 11 retracts, causing the baffle 12 to lift upwards and fully open the discharge port 25. The second motor 19 in the support boxes 15 on both sides synchronously drives the material-pushing plate 17 to rotate to a horizontally unfolded state. The soft scraper 18 on the outer side of the material-pushing plate 17 closely adheres to the inner wall of the tank body 2. The hydraulic telescopic rod 14 drives the support box 15 and the material-pushing plate 17 to move downwards at a uniform speed. The scraper 18 simultaneously scrapes off the mugwort residue adhering to the tank wall, preventing the waste of raw materials stuck to the wall. The horizontal material-pushing plate 17 simultaneously squeezes the waste residue downwards, pushing the material towards the bottom discharge port 25. During the feeding process, the second motor 19 on the side away from the discharge port 25 is controlled separately to drive the material-pushing plate 17 on that side to continuously deflect and rotate in one direction towards the discharge port 25. With the lateral thrust of the material-pushing plate 17, the mugwort waste residue remaining in the corner of the tank body 2 is continuously pushed towards the discharge port 25, avoiding material retention in the tank and achieving complete material pushing in the tank.

[0048] When the waste reaches the discharge port 25, the discharge motor 24 on the outside of the discharge port 25 drives the cross fork 26 to rotate continuously in a circular motion, breaking up the tangled and easily blocked Artemisia argyi fibers in the discharge port 25 to prevent material blockage. The cross fork 26 simultaneously drives the first connecting rod 28 to swing in a circular motion, pulling the second connecting rod 29 to reciprocate, driving the discharge fork 30 to slide up and down along the slide groove 34 of the discharge channel 27 and rotate synchronously. When the discharge fork 30 slides down along the slide groove 34, it rotates forward with the pressure of the second connecting rod 29, actively pushing the waste in the channel to slide down faster. When the discharge fork 30 returns upward, the second connecting rod 29 swings in the opposite direction, driving the discharge fork 30 to rotate upward and lift, avoiding the material falling into the channel and preventing the return stroke from carrying material and causing channel blockage. The cycle completes the automated unblocking and discharge. Through the continuous pressure of the single-sided material plate 17 and the reciprocating movement of the cross fork 26 and the discharge fork 30, the material is discharged quickly.
