Description

Technical Field

[0001] This utility model relates to the technical field of rose hydrosol extraction, specifically to a hydrosol extraction device for extracting rose essential oil. Background Technology

[0002] Rose essential oil and rose hydrosol are both natural products extracted from rose petals. Their industrial production usually uses steam distillation. After the distilled steam is condensed, a mixture of rose essential oil and hydrosol is obtained, which needs to be further separated into oil and water.

[0003] Common rose essential oil and hydrosol separators are typically designed as a container with an inlet and separate outlet pipes for essential oil and hydrosol. The inlet is usually located at the bottom of the container, while the essential oil outlet pipe is positioned higher than the hydrosol outlet pipe. Because of the density difference between essential oil and hydrosol, the essential oil floats on top of the hydrosol. As the water level continues to rise at the bottom of the container, the essential oil layer is discharged through the outlet pipes. If there is too much hydrosol in the container, the outlet pipe at the bottom of the container is opened to release some of the hydrosol, and this process is repeated.

[0004] In the aforementioned device, the oil-water separation process requires repeated manual operation to remove the hydrosol, preventing the hydrosol level from becoming too high and overflowing from the upper essential oil outlet, making the operation complex. Furthermore, the small essential oil droplets dispersed in the hydrosol separate slowly; they only separate more quickly and float upwards into the essential oil layer after aggregating into larger droplets. Utility model content:

[0005] The present invention aims to provide a hydrosol extraction device for extracting rose essential oil, which accelerates the separation of rose essential oil and hydrosol and simplifies the operation process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] 1) A hydrosol extraction device for extracting rose essential oil, comprising a separation barrel, wherein a feed pipe for adding material into the separation barrel and a hydrosol discharge pipe for discharging hydrosol are provided on both sides of the lower end of the separation barrel, and an essential oil discharge pipe on one side of the upper end of the separation barrel, which is on the same side as the hydrosol discharge pipe; a jet structure is provided at the bottom of the separation barrel, and an anti-disturbance baffle is provided above the jet structure in the separation barrel; a high-pressure gas storage tank is provided on one side of the separation barrel, and a gas supply pipe is provided in the high-pressure gas storage tank, which is connected to the jet structure.

[0008] In this invention, when the rose essential oil and hydrosol are first separated, the hydrosol discharge pipe is closed, and the mixture of rose essential oil and hydrosol is introduced through the feed pipe. Because the density of rose essential oil is less than that of rose hydrosol and the two are immiscible, the rose essential oil will float upward and gather on the upper layer of the mixture to form an essential oil layer. The essential oil layer rises with the rise of the liquid level of the mixture during the feeding process, and is discharged after reaching the essential oil discharge pipe at the top of the separation tank.

[0009] After the jet structure is activated, high-pressure gas is injected into the mixture from the bottom of the separation tank through the jet structure. The high-pressure gas agitates the mixture, causing the tiny essential oil droplets to collide and aggregate into larger, more easily separated essential oil droplets. As the gas rises, it carries the essential oil droplets upwards and into the essential oil layer more quickly, accelerating the separation speed of rose essential oil and hydrosol.

[0010] An anti-disturbance baffle is installed above the jet structure, ensuring that the disturbance of the mixture by the high-pressure gas mainly occurs between the baffle and the jet structure. This prevents excessive disturbance of the upper essential oil layer by the high-pressure gas, which could affect water-oil separation. When there is too much rose hydrosol in the separation tank and it is about to overflow from the essential oil outlet, the feeding and air intake are stopped, and the hydrosol discharge pipe is opened to discharge a portion of the hydrosol.

[0011] 2) The hydrosol extraction apparatus for extracting rose essential oil as described in 1), wherein:

[0012] It also includes a microprocessor and a capacitive sensor for detecting the hydrosol level interface. The capacitive sensor is installed on the side of the separation tank facing the inside of the separation tank. The capacitive sensor is located below and close to the essential oil outlet pipe. A first control valve is provided in the inlet pipe, a second control valve is provided in the hydrosol outlet pipe, and a third control valve is provided in the gas delivery pipe. The microprocessor is electrically connected to the capacitive sensor, the first control valve, the second control valve, and the third control valve, respectively.

[0013] In this invention, the microprocessor controls the first, second, and third control valves after receiving detection information from the capacitive sensor to initiate the rose hydrosol extraction process. When the sensor detects the hydrosol level interface, it indicates that there is too much hydrosol in the separation tank, reaching a position close to the essential oil outlet pipe. Upon receiving this signal, the microprocessor causes the first control valve to close the inlet pipe to stop feeding, and simultaneously causes the third control valve to close the gas supply pipe to stop air intake. After standing for five minutes to allow the essential oil and hydrosol to separate more fully, the second control valve opens the hydrosol outlet pipe to extract the rose hydrosol.

[0014] 3) The hydrosol extraction apparatus for extracting rose essential oil as described in 2), wherein:

[0015] A level gauge is installed above the anti-disturbance baffle. The level gauge is mounted on the side of the separation tank facing the inside of the separation tank and is electrically connected to the microprocessor.

[0016] In this invention, the microprocessor receives detection information from the level gauge and controls the first, second, and third control valves to stop the hydrosol export process and start the feeding and air intake process. When the level gauge detects that the liquid level is lower than the level gauge position, the microprocessor receives this signal and causes the second control valve to close the hydrosol export pipe to stop exporting rose hydrosol. Then, it causes the first control valve to open the feed pipe to start feeding, and simultaneously causes the third control valve to open the air supply pipe to start air intake.

[0017] The microprocessor receives detection information from capacitive sensors and level gauges, and controls the alternating operation of the feeding and air intake process and the rose hydrosol extraction process, avoiding complicated manual operation and simplifying the operation process through automated control.

[0018] 4) The hydrosol extraction apparatus for extracting rose essential oil as described in 1), wherein:

[0019] The jet structure includes an air intake pipe, which is connected to the gas supply pipe of the high-pressure gas storage tank. The air intake pipe passes through the bottom of the separation barrel and is connected to a spiral coil inside the separation barrel. The spiral coil is located on the bottom surface of the separation barrel. The spiral coil is a flat disc formed by spiraling outward from the center point of the separation barrel. The spiral coil has a plurality of uniform holes facing the top of the separation barrel.

[0020] In this invention, high-pressure gas enters the inlet pipe through the gas delivery pipe of the high-pressure gas storage tank, then enters the spiral tube coil from the inlet pipe, and then enters the separation tank body from the spiral tube coil. Finally, it is evenly dispersed into the mixture through the holes on the spiral tube coil, causing the fine essential oil droplets in the mixture to collide and gather into larger essential oil droplets. As the high-pressure gas moves upward, it carries the essential oil droplets into the essential oil layer above the mixture, accelerating the separation speed of rose essential oil and hydrosol.

[0021] 5) The hydrosol extraction apparatus for extracting rose essential oil as described in 1), wherein:

[0022] The anti-disturbance baffle has several through holes evenly distributed throughout. In this invention, the anti-disturbance baffle is used to prevent high-pressure gas from disturbing the upper essential oil layer of the mixture and affecting oil-water separation, while the through holes ensure that the process of essential oil droplets floating upwards is not affected.

[0023] 6) The hydrosol extraction apparatus for extracting rose essential oil according to 1), wherein:

[0024] The essential oil outlet pipe is arranged parallel to the outside of the separating tank and then angled downwards. A one-way valve is provided on the part of the essential oil outlet pipe near the separating tank. In this invention, the angled downward arrangement of the essential oil outlet pipe facilitates the flow and discharge of essential oil, and the one-way valve ensures that the essential oil can only enter the essential oil outlet pipe from the separating tank during the discharge process, preventing backflow.

[0025] Compared with the prior art, this utility model also has the following technical effects:

[0026] In this invention, a microprocessor receives detection information from a capacitive sensor and a level gauge, and controls the first, second, and third control valves to control the separation process of rose essential oil and hydrosol, alternating between the feeding and air intake process and the rose hydrosol extraction process. During the feeding and air intake process, the microprocessor closes the second control valve to stop the extraction of rose hydrosol, then opens the first control valve to start feeding through the feeding pipe, and simultaneously opens the third control valve to start air intake. During the hydrosol extraction process, the microprocessor controls the first control valve to close the feeding pipe to stop feeding, and simultaneously closes the third control valve to stop air intake. After a five-minute settling period to allow for more complete separation of the essential oil and hydrosol, the second control valve opens the hydrosol extraction pipe to extract the rose hydrosol. This automated control of the rose essential oil and hydrosol separation process by the microprocessor avoids cumbersome manual operations and simplifies the process.

[0027] Meanwhile, during the feeding and air intake process, high-pressure gas is evenly dispersed into the mixture from the bottom of the separation tank through the jet structure, causing the tiny essential oil droplets in the mixture to collide and aggregate into larger essential oil droplets. As the high-pressure gas moves upward, it carries the essential oil droplets into the essential oil layer above the mixture, accelerating the separation speed of rose essential oil and hydrosol.

[0028] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] In the above description of this utility model, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0037] See the example. Figure 1 and Figure 2As shown, this embodiment is a hydrosol extraction device for extracting rose essential oil, including a separation tank 1. The bottom of the separation tank 1 is supported by a bracket. The lower end of the separation tank 1 is provided with a feeding pipe 3 for adding material into the separation tank 1 and a hydrosol discharge pipe 4 for discharging hydrosol. The upper end of the separation tank 1 is provided with an essential oil discharge pipe 2 on the same side as the hydrosol discharge pipe 4. The bottom of the separation tank 1 is provided with a jet structure. The separation tank 1 is provided with an anti-disturbance baffle 11 located above the jet structure. The separation tank 1 is provided with a high-pressure gas storage tank 15 on one side. The high-pressure gas storage tank 15 is provided with a gas delivery pipe 14, which is connected to the jet structure.

[0038] In this embodiment, when the separation of rose essential oil and hydrosol begins, the hydrosol discharge pipe 4 is closed, and the mixture of rose essential oil and hydrosol is introduced from the feed pipe 3. Because the density of rose essential oil is less than that of rose hydrosol and the two are immiscible, the rose essential oil will float upward and gather on the upper layer of the mixture to form an essential oil layer. The essential oil layer rises with the rise of the liquid level of the mixture during the feeding process, and is discharged after reaching the position of the essential oil discharge pipe 2 at the upper end of the separation tank 1.

[0039] After the jet structure is activated, high-pressure gas is injected into the mixture from the bottom of the separation tank 1 through the jet structure. The high-pressure gas agitates the mixture, causing the tiny essential oil droplets to collide and aggregate into larger, more easily separated essential oil droplets. As the gas rises, it carries the essential oil droplets upwards and into the essential oil layer more quickly, accelerating the separation speed of rose essential oil and hydrosol.

[0040] An anti-disturbance baffle 11 is installed above the jet structure, so that the disturbance of the mixture by the high-pressure gas mainly exists between the anti-disturbance baffle 11 and the jet structure, avoiding excessive disturbance of the upper essential oil layer by the high-pressure gas, which would affect the water-oil separation. When there is too much rose hydrosol in the separation tank 1 and it is about to overflow from the essential oil outlet, the feeding and air intake are stopped, and the hydrosol discharge pipe 4 is opened to discharge part of the hydrosol.

[0041] This embodiment also includes a microprocessor and a capacitive sensor 10 for detecting the hydrosol level interface. The capacitive sensor 10 is selected as the M18 three-wire DC NPN capacitive sensor of Xinsen Zheng Electric. The capacitive sensor 10 is installed on the side of the separation tank 1 facing the inside of the separation tank 1. The capacitive sensor 10 is located below and close to the essential oil outlet pipe 2. A first control valve 6 is provided in the feed pipe 3, a second control valve 7 is provided in the hydrosol outlet pipe 4, and a third control valve 8 is provided in the gas supply pipe 14. The microprocessor is electrically connected to the capacitive sensor 10, the first control valve 6, the second control valve 7, and the third control valve 8 respectively.

[0042] In this embodiment, the microprocessor controls the first control valve 6, the second control valve 7, and the third control valve 8 after receiving the detection information from the capacitive sensor 10 to begin the rose hydrosol export process. When the sensor detects the hydrosol level interface, it indicates that there is too much hydrosol in the separation tank 1, reaching a position close to the essential oil outlet pipe 2. After receiving this signal, the microprocessor causes the first control valve 6 to close the feed pipe 3 to stop feeding, and at the same time causes the third control valve 8 to close the air supply pipe 14 to stop air intake. After standing for five minutes to allow the essential oil and hydrosol to separate more fully, the second control valve 7 opens the hydrosol outlet pipe 4 to export the rose hydrosol.

[0043] A level gauge 9 is provided above the anti-disturbance baffle 11. The level gauge 9 is installed on the side of the separation tank 1 facing the inside of the separation tank 1. The level gauge 9 is a side-mounted magnetic flap level gauge from Jiangsu Desen Instrument Co., Ltd. The level gauge 9 is electrically connected to the microprocessor.

[0044] In this embodiment, the microprocessor, upon receiving detection information from the level gauge 9, controls the first control valve 6, the second control valve 7, and the third control valve 8 to stop the hydrosol export process and begin the feeding and air intake process. When the level gauge 9 detects that the liquid level is lower than the level gauge 9 position, the microprocessor receives this signal and causes the second control valve 7 to close the hydrosol export pipe to stop exporting rose hydrosol. Then, it causes the first control valve 6 to open the feed pipe 3 to start feeding, and simultaneously causes the third control valve 8 to open the air supply pipe 14 to start air intake.

[0045] The microprocessor receives detection information from the capacitive sensor 10 and the level gauge 9, and controls the alternating operation of the feeding and air intake process and the rose hydrosol export process, avoiding complicated manual operation and simplifying the operation process through automated control.

[0046] The jet structure includes an air inlet pipe 13, which is connected to the gas delivery pipe 14 of the high-pressure gas storage tank 15. The air inlet pipe 13 passes through the bottom of the separation barrel 1 and is connected to the spiral tube 12 inside the separation barrel 1. The spiral tube 12 is located on the bottom surface of the separation barrel 1. The spiral tube 12 is a flat disc formed by spiraling outward from the center point of the separation barrel 1. The spiral tube 12 has a plurality of uniform holes facing the top of the separation barrel 1.

[0047] In this embodiment, high-pressure gas enters the inlet pipe 13 through the gas supply pipe 14 of the high-pressure gas storage tank 15, then enters the spiral tube 12 from the inlet pipe 13, and then enters the separation tank 1 from the spiral tube 12. Finally, the mixture is evenly dispersed from the holes on the spiral tube 12, causing the fine essential oil droplets in the mixture to collide and gather into larger essential oil droplets. As the high-pressure gas moves upward, it carries the essential oil droplets into the essential oil layer above the mixture, accelerating the separation speed of rose essential oil and hydrosol.

[0048] The anti-disturbance baffle 11 has several through holes evenly distributed. In this embodiment, the anti-disturbance baffle 11 is used to prevent high-pressure gas from disturbing the essential oil layer at the top of the mixture and affecting oil-water separation. The through holes ensure that the process of the essential oil droplets floating upward is not affected.

[0049] The essential oil outlet pipe 2 is arranged parallel to the outside of the separation tank 1 and then angled downwards. A one-way valve 5 is provided near the separation tank 1 of the essential oil outlet pipe 2. In this embodiment, the angled downward arrangement of the essential oil outlet pipe 2 facilitates the flow and discharge of essential oil. The one-way valve 5 ensures that the essential oil can only enter the essential oil outlet pipe 2 from the separation tank 1 during the discharge process and cannot flow back.

[0050] In this embodiment, the microprocessor receives detection information from the capacitive sensor 10 and the level gauge 9 and controls the first control valve 6, the second control valve 7, and the third control valve 8 to control the separation process of rose essential oil and hydrosol, allowing the feeding and air intake process and the rose hydrosol output process to run alternately. During the feeding and air intake process, the microprocessor causes the second control valve 7 to close the hydrosol output pipe to stop the output of rose hydrosol, then causes the first control valve 6 to open the feeding pipe 3 to start feeding, and simultaneously causes the third control valve 8 to open the air supply pipe 14 to start air intake. During the hydrosol output process, the microprocessor controls the first control valve 6 to close the feeding pipe 3 to stop feeding, and simultaneously causes the third control valve 8 to close the air supply pipe 14 to stop air intake. After standing for five minutes to allow the essential oil and hydrosol to separate more fully, the second control valve 7 opens the hydrosol output pipe 4 to output the rose hydrosol. The automated control of the rose essential oil and hydrosol separation process by the microprocessor avoids cumbersome manual operations and simplifies the operation process.

[0051] Meanwhile, during the feeding and air intake process, high-pressure gas is evenly dispersed into the mixture from the bottom of the separation tank 1 through the jet structure, causing the small essential oil droplets in the mixture to collide and aggregate into larger essential oil droplets. As the high-pressure gas moves upward, it carries the essential oil droplets into the essential oil layer above the mixture, accelerating the separation speed of rose essential oil and hydrosol.
