Description

Technical Field

[0001] This invention relates to the field of essential oil extraction technology, specifically to an essential oil extraction device capable of separating oil and water. Background Technology

[0002] Essential oil extraction devices are specialized equipment used to separate volatile aromatic components from plant materials using physical or chemical methods. For example, they can extract and separate volatile aromatic essential oils from aromatic plants (fruit peels, bark, flowers, leaves, roots, etc.). The extracted essential oils are characterized by being insoluble in water and having a low boiling point. The core principle is mostly steam distillation, which uses heating to generate steam that carries the volatile components of plant essential oils. After condensation and liquefaction, the oil and water are separated and collected using density differences.

[0003] Existing essential oil extraction devices separate plant essential oils into oil and water by condensing and liquefying them. However, the water after separation is directly purified and discharged, which wastes the essential oil. Furthermore, the condensation effect cannot be adjusted according to changes in the amount of steam, which can easily lead to a decrease in the amount of essential oil extracted and affect the company's production efficiency.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example: Figures 1-9 As shown, the present invention provides a technical solution for an essential oil extraction device capable of separating oil and water. The essential oil extraction device includes a base plate 6, on which an extraction tank 1, a condensation component 2, and an oil-water separation unit 3 are sequentially mounted. The extraction tank 1 is provided with a raw material pipe 11, a liquid inlet pipe 12, a heating module 13, and a control valve 14. The gas output end of the extraction tank 1 is connected to the input end of the condensation component 2 through a steam conveying component 4. The output end of the condensation component 2 is connected to the input end of the oil-water separation unit 3 through a pipe. The output end of the oil-water separation unit 3 is connected to the control valve 14 through a reflux conveying component 5.

[0041] The condensation assembly 2 is equipped with a condensation regulating component 26, an airflow regulating component 27, a flow regulating component 28, and an extending agitator 29;

[0042] The return conveying assembly 5 includes a circulation pump 51, a conveying pipe 52, a return pipe 53, and a solenoid valve 54;

[0043] A circulation pump 51 is mounted on the substrate 6. The input end of the circulation pump 51 is connected to the output end of the oil-water separation unit 3 through a return pipe 53. The output end of the circulation pump 51 is connected to the control valve 14 through a delivery pipe 52. A solenoid valve 54 is installed on the delivery pipe 52.

[0044] Raw materials and soaking liquid are fed into extraction tank 1 through raw material pipe 11 and liquid inlet pipe 12. The raw liquid in extraction tank 1 is heated by heating module 13 to generate steam carrying plant essential oil volatiles. The steam is transported to condensation component 2 through steam conveyor 4 for condensation and liquefaction. The condensation component 2 can automatically adjust the condensation effect according to the change in steam volume. After condensation and liquefaction, the liquid can enter the oil-water separation unit 3 through pipes to facilitate oil-water separation of the essential oil mixture. At the same time, control valve 14 is opened and circulation pump 51 and solenoid valve 54 are started. The raw liquid separated by oil-water separation unit 3 can be transported back to extraction tank 1 through return pipe 53 and conveying pipe 52. This can realize secondary heating and evaporation of the raw liquid, which can improve the extraction effect of essential oil.

[0045] The condenser assembly 2 includes a base plate 21, a tank body 22, a baffle 23, a connection hole 24, and a condenser tube 25;

[0046] A base plate 21 is mounted on the base plate 6, and a tank 22 is mounted on the base plate 21. Baffles 23 are symmetrically installed inside the tank 22, and multiple connection holes 24 are opened on each of the baffles 23. The corresponding connection holes 24 on both sides are connected by condenser pipes 25. The tank 22 forms a cooling chamber through the baffles 23 on both sides. A condensation regulating component 26 is provided on the cooling chamber. The input end of the tank 22 is connected to the extraction tank 1 through a steam conveying component 4, and an airflow regulating component 27 is provided at the baffle 23 near the input end inside the tank 22. The output end of the tank 22 is connected to the input end of the oil-water separation unit 3 through a pipe. When steam enters the tank 22 through the steam conveying component 4, the condensation regulating component 26 and the airflow regulating component 27 can be self-adjusted according to the change in the amount of steam generated in the extraction tank 1, so as to ensure the liquefaction effect of the condenser pipe 25 on the steam.

[0047] The condenser regulating component 26 includes a cooling box 261, a pump 262, a suction pipe 263, a delivery pipe 264, a return pipe 265, a regulating valve 266, and a cooling plate 267;

[0048] A cooling tank 261 and a pump 262 are mounted on the base plate 21. The input end of the pump 262 is connected to the cooling tank 261 via a suction pipe 263, and the output end of the pump 262 is connected to the cooling chamber via a delivery pipe 264. The cooling chamber is connected to the cooling tank 261 via a return pipe 265. Cooling plates 267 are symmetrically installed inside the cooling tank 261. A regulating valve 266 is installed on the return pipe 265. A steam volume sensor is installed inside the extraction tank 1, and the steam volume sensor is electrically connected to the regulating valve 266. A flow regulating component 28 is installed on the cooling tank 261. When the pump 262 is started, steam can flow through the suction pipe 263 and the delivery pipe 264. Liquid pipe 264 delivers coolant from cooling tank 261 to cooling chamber of tank 22, facilitating the coolant's heat absorption and condensation of steam in condenser pipe 25. The coolant carrying heat can also flow back to cooling tank 261 through return pipe 265, allowing cooling plate 267 in cooling tank 261 to cool the coolant, ensuring continuous circulation and condensation of the coolant. When the amount of steam generated in extraction tank 1 increases, the steam quantity sensor detects the change in steam quantity. At this time, the steam quantity sensor can control the opening of regulating valve 266 to increase accordingly, automatically adjusting the circulation flow rate of coolant based on the change in steam quantity.

[0049] The airflow regulating component 27 includes a vertical plate 271, a fixed column 272, a rotating rod 273, a ring rail 274, a slide block 275, a folding baffle 276, and a fixing ring 277;

[0050] A fixing ring 277 is installed inside the tank 22 near the baffle 23 at the input end. Vertical plates 271 are symmetrically installed on the fixing ring 277 and connected to each other by a fixing column 272. Two rotating rods 273 are rotatably installed on the fixing column 272. Two ring rails 274 are installed on the fixing ring 277, and slide seats 275 are slidably installed on each of the two ring rails 274. The slide seats 275 are connected to the rotating rods 273, and the two rotating rods 273 are connected by a folding baffle 276. The ring rails 274 are electrically connected to a steam quantity sensor. When the amount of steam generated in the extraction tank 1 increases, the steam quantity sensor detects the change in steam quantity. At this time, the steam quantity sensor can control the two slide seats 275 on the two ring rails 274 to move in opposite directions, thereby increasing the angle between the two rotating rods 273. This allows for real-time adjustment of the angle between the two rotating rods 273 according to the change in steam quantity, which is beneficial for controlling the shading area of ​​the folding baffle 276 on the baffle 23 according to the change in steam quantity, thereby increasing the steam throughput.

[0051] The fixed column 272 is located at the center of the baffle 23 and on the same central axis, and the slides 275 on the two ring rails 274 always move in opposite directions.

[0052] In the initial state: the two rotating rods 273 and the folded baffle 276 cover the baffle 23 to the maximum extent;

[0053] When the steam volume is at its maximum: the two rotating rods 273 and the folded baffle 276 cover the baffle 23 to the minimum area.

[0054] The flow regulating component 28 includes a drive motor 281, a drive wheel 282, a rotating shaft 283, a driven wheel 284, a transmission belt 285, a transmission gear 286, and a driven gear 287;

[0055] A drive motor 281 is mounted on a cooling box 261. A drive wheel 282 is mounted on the output shaft of the drive motor 281. Multiple rotating shafts 283 are evenly installed inside the cooling box 261. Each rotating shaft 283 is equipped with an extending agitator 29. Driven wheels 284 are installed at intervals on the same side of the multiple rotating shafts 283. A transmission belt 285 is fitted onto the drive wheel 282 and the driven wheel 284. A transmission tooth 286 is installed on the other end of the rotating shaft 283 connected to the driven wheel 284. A driven tooth 287 is installed on the end of the adjacent rotating shaft 283 near the transmission tooth 286. The driven tooth 287 meshes with the transmission tooth 286. The drive motor 281 is electrically connected to a steam quantity sensor. When the drive motor 281 runs, the steam generated by the drive wheel 282, driven wheel 284, and transmission belt 285... The belt drive allows the driven wheel 284 to drive the extended agitator 29 on the rotating shaft 283 to rotate. At the same time, the driven wheel 284 can drive the transmission gear 286 to synchronize. Through the meshing of the transmission gear 286 and the driven gear 287, two adjacent extended agitators 29 can rotate in opposite directions, which is beneficial to form vortices in the cooling tank 261 and improve the cooling effect of the cooling plate 267 on the coolant. Meanwhile, when the amount of steam generated in the extraction tank 1 increases, the steam quantity sensor detects the change in steam quantity. At this time, the steam quantity sensor can control the operating power of the drive motor 281 to be increased accordingly, which can increase the speed of the drive wheel 282 and automatically adjust the agitation frequency of the coolant according to the change in steam quantity.

[0056] The rotation direction of the drive wheel 282 is the same as the flow direction of the coolant in the cooling tank 261.

[0057] The extended agitator 29 includes a rotating roller 291, a fixed plate 292, a chamber 293, a slide 294, a sliding plate 295, an electric telescopic rod 296, and an extended plate 297;

[0058] Multiple rotating shafts 283 are fixedly fitted with rotating rollers 291. Multiple fixed plates 292 are installed in a circumferential array on the rotating rollers 291. Each fixed plate 292 has a cavity 293. A slide rail 294 is opened on the side of the cavity 293 away from the rotating rollers 291. A slide plate 295 is slidably installed in the cavity 293. An electric telescopic rod 296 is installed in the cavity 293. The telescopic end of the electric telescopic rod 296 is connected to the slide plate 295. An extension plate 297 is installed on the side of the slide plate 295 away from the electric telescopic rod 296. The extension plate 297 passes through the slide rail 294 and is in sliding fit. The electric telescopic rod 296 is electrically connected to the steam quantity sensor.

[0059] Working principle of the invention:

[0060] Raw materials and soaking liquid are fed into extraction tank 1 through raw material pipe 11 and liquid inlet pipe 12. Heating module 13 heats the original liquid in extraction tank 1 to generate steam carrying plant essential oil volatiles. When the steam enters tank body 22 through steam conveyor 4, the coolant absorbs heat and condenses the steam in condenser pipe 25. A steam quantity sensor detects changes in steam quantity and controls the opening of regulating valve 266 to increase accordingly, automatically adjusting the coolant circulation flow rate. Simultaneously, the angle between the two rotating rods 273 can be adjusted in real time according to changes in steam quantity, which helps control the shading area of ​​the folding baffle 276 on baffle 23, increasing steam throughput. Furthermore, the steam quantity sensor can control the operating power of drive motor 281 to increase accordingly, enabling the adjacent extended agitators to operate more efficiently. The increased speed of the opposing rotation of the moving parts 29 facilitates the formation of vortices within the cooling tank 261, automatically adjusting the agitation frequency of the coolant. It also allows the steam sensor to control the extension of the electric telescopic rod 296 according to steam changes, enabling automatic adjustment of the combined area of ​​the extension plate 297 and the fixed plate 292 based on steam volume variations. This allows for automatic adjustment of the coolant agitation range according to steam volume changes. After condensation and liquefaction, the coolant can enter the oil-water separation unit 3 through a pipeline, facilitating oil-water separation of the essential oil mixture. Simultaneously, opening the control valve 14 activates the circulation pump 51 and solenoid valve 54, allowing the original liquid separated by the oil-water separation unit 3 to be transported back to the extraction tank 1 via the return pipe 53 and the delivery pipe 52. This enables secondary heating and evaporation of the original liquid, improving the extraction effect of the essential oil.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
