Description

Technical Field

[0001] The invention relates to the technical field of plant essential oil extraction, and more specifically to a plant essential oil filtration extraction system and a filtration extraction process. Background Art

[0002] The plant essential oil filtration and extraction system is a device system specially used to extract and filter essential oils from plant materials. During the plant essential oil filtration and extraction process, the plant needs to be placed in a distiller and heated to volatilize the essential oil components. Then, the distilled steam is condensed into liquid using a condenser, and the density difference between essential oil and water is used to filter and separate, and the pure essential oil is collected.

[0003] In the process of extracting essential oils from plants, oil-water separation requires the oil-water mixture to be introduced into a separation tank. According to the difference in density between oil and water, natural stratification is achieved, in which water is deposited in the lower layer due to its greater density, while oil floats on the upper layer. Subsequently, by guiding the upper layer of oil to flow out, the purpose of effective separation of oil and water can be achieved. However, the composition ratio of the oil-water mixture obtained by distillation varies from batch to batch. When the oil-water mixture enters the separation tank, if the oil layer height is too high, some water may still be mixed in the oil at the beginning of separation, affecting the separation purity. If the oil layer height is too low, it may lead to incomplete separation, resulting in oil residue, which will have an adverse effect on the final quality of essential oil filtration and separation.

[0011] Furthermore, a shielding cover is fixedly connected to the top of the evaporation box, the top of the shielding cover is connected to an exhaust pipe, and the long arm end of the oil delivery pipe is inserted into the top of the shielding cover.

[0012] Furthermore, a mesh plate is fixedly connected to the inner upper end of the separation tank.

[0016] A filtering and extraction process for a plant essential oil filtering and extraction system, characterized in that it comprises the following steps:

[0017] Step 1: First, rotate the rotating sleeve to move the lower pressure ring upwards to release the fixation of the vent pipe height, then adjust the height of the vent pipe so that the connection between the vent pipe and the oil delivery hose is parallel to the bottom layer of the oil surface, then rotate the rotating sleeve in the opposite direction to move the lower pressure ring downwards and fix the vent pipe with the elastic clip;

[0018] Step 2: Then, the oil-water mixture is injected into the separation tank through the water inlet pipe, the essential oil at the top flows into the oil delivery hose, and the water at the bottom is discharged through the water outlet pipe and the water outlet return pipe, thereby achieving the filtration and separation of the essential oil;

[0019] Step 3: At the same time, the impact of the fluid will drive the blades to rotate, and then drive multiple stirring blades to rotate, which can break up larger solidified essential oils;

[0020] Step 4: Then, the solidified essential oil can be filtered and intercepted when it floats upward through the mesh plate, the heating wire heats the water, the hot water is transferred to the mesh plate, and the intercepted solid essential oil melts;

[0021] Step 5: At the same time, the flow of the oil-water mixture can drive the first blade to rotate, and then drive the active rotating frame and the magnet block on its surface to rotate, and then drive the connecting rotating frame to rotate, and further drive the passive rotating frame and its magnet block to rotate, and finally drive the second blade to rotate. The rotation of the second blade can absorb the essential oil into the oil delivery pipe;

[0022] Step 6: Finally, the essential oil is heated by the heating wire to evaporate the residual water in the essential oil. The water vapor generated by evaporation is discharged through the exhaust pipe, and the essential oil flows out through the oil outlet pipe.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) When the oil level is too high or too low, this solution can adjust the position of the connection between the vent pipe and the oil hose so that it is horizontally aligned with the lowest interface of the oil layer in the oil-water mixture and adapt to different oil level heights, thereby optimizing the oil-water separation efficiency, ensuring more thorough oil-water separation and effectively reducing the amount of residual oil, thereby improving the quality of essential oil filtration and separation.

[0025] (2) In this solution, when the essential oil flows into the evaporation box, the heating wire in the evaporation box is used to heat the essential oil, and the residual water in the essential oil can be heated to ensure that the residual water is completely evaporated. As the water evaporates, the generated water vapor is discharged through the exhaust pipe, and the evaporated essential oil flows out through the oil outlet pipe, thereby improving the removal efficiency of the water in the essential oil and further improving the quality of the essential oil filtration and separation.

[0026] (3) This solution uses a mesh plate to effectively filter and intercept the essential oil when it floats upward after solidification, ensuring that the solidified essential oil cannot continue to float up. This can prevent the essential oil from solidifying due to differences in essential oil types or extraction environmental conditions, especially when the ambient temperature is too low, from blocking the oil delivery hose and hindering the normal discharge process of the essential oil.

[0027] (4) In this solution, when the heating wire is heated, its heat energy acts on the water at the same time, raising the water temperature. The hot water then transfers the heat to the mesh plate, so the solid essential oil intercepted by the mesh plate gradually melts due to the heat until its fluidity increases and it can smoothly pass through the pores of the mesh plate and continue to float up. This not only effectively avoids the problem of clogging of the delivery hose caused by the solidification of the solid essential oil, but also prevents the solid essential oil from accumulating on the mesh plate, which may hinder the normal circulation of the oil-water mixture.

[0028] (5) In this scheme, when the oil-water mixture is injected into the separation tank through the water inlet pipe, the impact of the fluid will drive the rotating blades to rotate, and then link multiple stirring blades to break up larger solidified essential oils, which can accelerate the melting rate of the solidified essential oils, thereby preventing the solidified essential oils from accumulating on the mesh plate and ensuring the smooth flow of the oil-water mixture in the separation tank.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-Figure 5 A plant essential oil filtering and extraction system comprises a separation tank 1, a water inlet pipe 2 and a water outlet return pipe 3, a separation regulating mechanism, the separation regulating mechanism is arranged on the top of the separation tank 1, the separation regulating mechanism comprises an oil box 401 fixedly connected to the top of the separation tank 1, a vent pipe 402 is inserted inside the oil box 401, an oil delivery hose 409 is connected to the right side of the lower end of the vent pipe 402, the right end of the oil delivery hose 409 is connected to an oil outlet delivery pipe 404, and the oil outlet delivery pipe 404 is fixedly inserted inside the top of the oil box 401.

[0042] The lower end of the short arm end of the oil delivery pipe 404 is rotatably connected to a second rotating shaft 413, the left end of the second rotating shaft 413 penetrates into the interior of the oil delivery pipe 404 and is fixedly connected to a second fan blade 414, and the rotation of the second fan blade 414 can suck the essential oil into the oil delivery pipe 404 when the lowest height of the oil level in the oil box 401 is lower than the highest height of the oil delivery pipe 404, the inner top of the water inlet pipe 2 is fixedly connected to a support rod 411, the middle part of the support rod 411 is rotatably inserted with a first rotating shaft 412, and the right end of the first rotating shaft 412 is fixedly connected to There is a first fan blade 410, and the lower right end of the oil box 401 is rotatably connected to a rotating column 420, the end of the second rotating shaft 413 away from the second fan blade 414 is fixedly connected to a passive rotating frame 416, the right end of the rotating column 420 is fixedly connected to a connecting rotating frame 417, and the end of the first rotating shaft 412 away from the first fan blade 410 is fixedly connected to an active rotating frame 418, and the surfaces of the passive rotating frame 416, the connecting rotating frame 417 and the active rotating frame 418 are all fixedly connected to magnet blocks 415, and force transmission can be achieved through the magnetic force between the magnet blocks 415.

[0043] Among them, the top of the oil box 401 is fixedly connected with a connecting ring 408, and the top of the connecting ring 408 is fixedly connected with an elastic clip 407. The number of the elastic clips 407 is multiple and evenly arranged. The surface threaded sleeve of the connecting ring 408 is provided with a rotating sleeve 403. The up and down movement of the lower pressure ring 406 can be controlled by rotating the rotating sleeve 403. The inner surface of the rotating sleeve 403 is fixedly connected with a lower pressure ring 406. The lower pressure ring 406 moves downward to apply pressure to the elastic clip 407, and the ventilation pipe 402 is fixed by the elastic clip 407.

[0044] By adopting the above technical solution, the oil-water mixture is injected into the separation tank 1 through the water inlet pipe 2. As the liquid level of the oil-water mixture in the separation tank 1 rises to the connection between the vent pipe 402 and the oil delivery hose 409 in the oil box 401, the essential oil at the upper part flows into the oil delivery hose 409, while the water at the lower part is discharged through the water outlet pipe 405 and the water outlet return pipe 3, thereby realizing the filtration and separation of the essential oil. If the oil level is too high or too low, the lower pressure ring 406 can be moved upward by rotating the rotating sleeve 403 to release the elastic force. The pressure applied by the elastic clip 407 is released to release the fixation of the height of the vent pipe 402, and then the height of the vent pipe 402 is adjusted to make the connection between the vent pipe 402 and the oil delivery hose 409 parallel to the bottom layer of the oil surface. After the height adjustment of the vent pipe 402 is completed, the rotating sleeve 403 is rotated in the opposite direction to make the lower pressure ring 406 move downward to apply pressure to the elastic clip 407, and the vent pipe 402 is fixed by the elastic clip 407, so as to adapt to the oil-water mixture at different oil surface heights and improve the final quality of essential oil filtration and separation.

[0045] When the oil-water mixture is injected into the separation tank 1 through the water inlet pipe 2, the flow of the oil-water mixture can drive the first fan blade 410 to rotate, and then drive the active rotating frame 418 and the magnet block 415 on its surface to rotate, and the magnetic force between the magnet blocks 415 can drive the connecting rotating frame 417 to rotate. Similarly, the passive rotating frame 416 and its magnet block 415 can be further driven to rotate. As the passive rotating frame 416 rotates, the second fan blade 414 can be driven to rotate. Therefore, through the rotation of the second fan blade 414, when the lowest height of the oil level in the oil box 401 is lower than the highest height of the oil outlet delivery pipe 404, the essential oil can be sucked into the oil outlet delivery pipe 404, so that the essential oil can flow smoothly and the filtering and separation of the essential oil can be achieved.

[0046] like Figure 6 , Figure 8 and Fig. 9 As shown, a connecting frame 504 is fixedly connected to the right side of the separation tank 1, and an evaporation box 503 is fixedly connected to the right end of the connecting frame 504. The right end bottom of the evaporation box 503 is connected to an oil outlet pipe 515. A partition 517 is fixedly connected to the inside of the evaporation box 503, and the bottom of the evaporation box 503 is separated by the partition 517 to form a cavity. A heating wire 516 is fixedly connected to the inside of the cavity. The heating wire 516 is used to heat the essential oil, and the residual moisture can be heated to evaporate the residual moisture in the essential oil.

[0047] Among them, the left side of the separation tank 1 is connected to a water outlet pipe 405, and the top of the water outlet pipe 405 is connected to a liquid level observation tube 419. Since the water surface is connected and level, the height of the oil level can be observed at any time through the height of the liquid level in the transparent liquid level observation tube 419. The water outlet reflux pipe 3 is connected to the top of the liquid level observation tube 419, and the top of the evaporation box 503 is fixedly connected with a shielding cover 506, which can block the splashing essential oil to reduce the loss of essential oil. The top of the shielding cover 506 is connected to an exhaust pipe 514, and the water vapor generated by evaporation can be discharged through the exhaust pipe 514. The long arm end of the oil outlet delivery pipe 404 is inserted into the top of the shielding cover 506.

[0048] By adopting the above technical solution, after the essential oil flows out from the oil delivery pipe 404, it will flow into the evaporation box 503, and the essential oil in the evaporation box 503 will be heated by the heating wire 516 inside the evaporation box 503, so that the residual water in the essential oil can be heated, so that the residual water in the essential oil can be completely evaporated, and the water vapor generated by evaporation is discharged through the exhaust pipe 514, and the essential oil flows out through the oil outlet pipe 515, so as to further improve the filtering and extraction quality of the essential oil. Since the boiling point of the essential oil is greater than the boiling point of water, the essential oil may splash as the water evaporates during heating, so the splashing essential oil can be blocked by the shielding cover 506 to reduce the loss of the essential oil.

[0049] like Figure 6 and Figure 7 As shown, a mesh plate 501 is fixedly connected to the upper end of the separation tank 1, and the mesh plate 501 can be used to filter and intercept the solidified essential oil when it floats upward, so that the solidified essential oil cannot float up. A support cross bar 508 is fixedly connected to the middle section of the separation tank 1, and a third rotating shaft 509 is rotatably connected to the middle part of the upper surface of the support cross bar 508. A stirring blade 512 is fixedly connected to the top of the third rotating shaft 509. There are multiple stirring blades 512. The stirring blades 512 can be rotated to break up larger solidified essential oils, thereby increasing the amount of solidified essential oils. In order to increase the melting speed of the essential oil, a rotating frame 510 is fixedly sleeved on the surface of the third rotating shaft 509, and multiple branches of the rotating frame 510 are fixedly connected with blades 511. After the oil-water mixture is injected into the separation tank 1 through the water inlet pipe 2, the impact of the fluid will drive the blades 511 to rotate, providing a power source. The lower end of the water inlet pipe 2 is connected to an input pointing tube 507, and the interior of the input pointing tube 507 is fixedly connected with a guide inclined plate 513. The inclined guide inclined plate 513 can enable the oil-water mixture to accurately impact the blades 511.

[0050] Among them, the mesh plate 501 is a hollow structure. When hot water is transferred to the mesh plate 501, the solid essential oil melts when heated, thereby preventing the solidified essential oil from accumulating on the mesh plate 501. The left side of the mesh plate 501 is connected to a first water pipe 502, and the right side of the mesh plate 501 is connected to a second water pipe 505. The first water pipe 502 and the second water pipe 505 are fixedly inserted into the front and back surfaces of the lower end of the evaporation box 503, respectively, and are both connected to the cavity.

[0051] By adopting the above technical solution, due to the different types of essential oils and extraction environments, if the ambient temperature is too low, the essential oil may solidify. At this time, if the essential oil is filtered and separated, the solidified essential oil may block the oil delivery hose 409, resulting in the essential oil being unable to be discharged normally. Therefore, the mesh plate 501 can be used to filter and intercept the solidified essential oil when it floats upward, so that the solidified essential oil cannot float up. Since the cavity, the first water delivery pipe 502, the second water delivery pipe 505 and the mesh plate 501 are all filled with water, the water will also be heated when the heating wire 516 is heated. When the hot water is transferred to the mesh plate 501, the intercepted solid essential oil melts when it encounters heat until it can float through the gap of the mesh plate 501, thereby avoiding the solidified essential oil from clogging the delivery hose and also avoiding the solidified essential oil from accumulating on the mesh plate 501 to affect the circulation of the oil-water mixture.

[0052] After the oil-water mixture is injected into the separation tank 1 through the water inlet pipe 2, the impact of the fluid will drive the blades 511 to rotate, and then drive the rotating frame 510 and the third rotating shaft 509 to rotate. As the third rotating shaft 509 rotates, the multiple stirring blades 512 will be driven to rotate, and the larger solidified essential oil can be broken up, thereby accelerating the melting speed of the subsequent essential oil and preventing the solidified essential oil from accumulating on the mesh plate 501.

[0053] Usage: Inject the oil-water mixture into the separation tank 1 through the water inlet pipe 2, the essential oil at the top flows into the oil delivery hose 409, and the water at the bottom is discharged through the water outlet pipe 405 and the water outlet return pipe 3, thereby achieving the filtering and separation of the essential oil.

[0054] Rotate the rotating sleeve 403 to move the lower pressure ring 406 upward to release the height fixation of the vent pipe 402, then adjust the height of the vent pipe 402 so that the connection between the vent pipe 402 and the oil delivery hose 409 is parallel to the bottom layer of the oil surface, then rotate the rotating sleeve 403 in the opposite direction to move the lower pressure ring 406 downward, and fix the vent pipe 402 by the elastic clip 407.

[0055] The flow of the oil-water mixture can drive the first fan blade 410 to rotate, and then drive the active rotating frame 418 and the magnet block 415 on its surface to rotate, and then drive the connecting rotating frame 417 to rotate, and further drive the passive rotating frame 416 and its magnet block 415 to rotate, and finally drive the second fan blade 414 to rotate. The rotation of the second fan blade 414 can absorb the essential oil into the oil outlet pipe 404.

[0056] The essential oil is heated by the heating wire 516 to evaporate the residual water in the essential oil. The water vapor generated by the evaporation is discharged through the exhaust pipe 514 , and the essential oil flows out through the oil outlet pipe 515 .

[0057] The impact of the fluid will drive the blades 511 to rotate, and then drive the multiple stirring blades 512 to rotate, so as to break up the larger solidified essential oil.

[0058] The mesh plate 501 can be used to filter and intercept the solidified essential oil when it floats upward, and the heating wire 516 heats the water, and the hot water is transferred to the mesh plate 501, and the intercepted solid essential oil is melted.

[0059] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
