Description

Technical Field

[0001] The utility model relates to the technical field of extraction equipment, in particular to an efficient essential oil extraction equipment. Background Art

[0002] Plant essential oil is an aromatic substance extracted from plants. It is taken from the flowers, leaves, bark, fruits, seeds, resins, etc. of herbaceous plants as raw materials and extracted by distillation and pressing methods. Because the aromatic essential oil has high volatility and small molecules, it is very easy to be absorbed by the human body and can quickly penetrate into the internal organs of the human body, discharging the excess components out of the body. The whole process only takes a few minutes. Moreover, the fragrance of the plant itself directly stimulates the secretion of the pituitary gland, enzymes and hormones, etc., balancing the internal energy and playing a role in beauty and skin care. Basically, plant essential oil is extracted by the distillation method. When the existing distillation device works, it mixes the plant with water, and then generates steam by heating to extract the essential oil in the plant and transport it to the cooling device together with the steam for condensation and then transports it to the static container to wait for the oil-water separation. Finally, the water liquid is discharged and the essential oil is collected. In order to improve the distillation extraction effect of the plant, a stirring mechanism is usually added to the rectification device. By stirring, the contact area between the plant and the steam is enhanced to achieve the purpose of effective distillation extraction. However, the existing stirring mechanism has a single stirring method and is also easy to break and disperse the plant. The debris is easily carried into the cooling equipment along with the steam flow, which not only affects the use of the cooling equipment but also enters the static container for collection, bringing difficulties to the separation and collection of essential oil, and the essential oil extraction effect is poor.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] For the embodiment, please refer to Figures 1 to 5, An efficient essential oil extraction device, including a distillation tank 1, a heating device 2 is arranged at the bottom of the distillation tank 1. The heating device 2 can be an electric heating device, which belongs to the known prior art. The output end at the top of the distillation tank 1 is connected to a cooling device 29 through a connecting pipe 26. And a static collection tank 3 is also arranged on one side of the distillation tank 1. It also includes: a driving cylinder 4, a driving component, a partition plate 5 and a steam pipe 6. The driving cylinder 4 is arranged inside the distillation tank 1. The driving component is arranged between the distillation tank 1 and the driving cylinder 4 for making the driving cylinder 4 move up and down inside the distillation tank 1. The partition plate 5 is arranged on the lower side inside the distillation tank 1. And a placement cavity 7 is formed between the partition plate 5 and the lower part of the distillation tank 1. A plurality of steam pipes 6 are provided, and the plurality of steam pipes 6 are longitudinally arranged uniformly above the partition plate 5. The steam pipes 6 communicate with the inside of the placement cavity 7. And a number of exhaust holes 8 are arranged on the side wall of the steam pipe 6. A number of through holes 9 are arranged on the outer wall of the driving cylinder 4. And sliding holes 10 suitable for the steam pipes 6 to penetrate are arranged on the bottom side wall and the top side wall of the driving cylinder 4. And the steam pipes 6 penetrate through the driving cylinder 4 through the sliding holes 10. Plants can be placed through the driving cylinder 4. Through the driving component, the driving cylinder 4 (that is, the plants) can move up and down reciprocally inside the distillation cylinder. Water can be placed through the placement cavity 7. The water can be heated by the heating device 2 to generate steam. Through the relative up and down movement of the steam pipes 6 and the driving cylinder 4, the steam discharged from the steam pipes 6 can continuously distill different positions of the plants. The steam pipes 6 are directly inserted into the plants, which not only increases the distillation contact area with the plants, but also, under the up and down movement of the driving cylinder 4, can make the steam discharged from the steam pipes 6 continuously distill and extract different positions of the plants, improving the distillation and extraction effect and further enhancing the extraction of plant essential oils. Compared with the stirring method of the prior art, it can not only increase the contact area between the steam and the plants, but also reduce the dispersion of the plants, avoid debris from entering the cooling device 29 and the static collection tank 3, and improve the plant essential oil extraction effect.

[0038] It should be noted that a water inlet pipe 11 is connected to the side wall of the placement chamber 7, a water delivery pipe 12 is connected to the bottom input end of the cooling device 29, a drain pipe 13 is provided at the top output end of the cooling device 29, the drain pipe 13 and the water inlet pipe 11 are communicated through a tee pipe 14, the other end of the tee pipe 14 is connected with a connecting pipe 15, and valves 16 are arranged on the water inlet pipe 11, the connecting pipe 15 and the drain pipe 13.

By the rotation of the motor 30 to drive the cam 18 to rotate, under the action of the spring 17 and with the sliding fit between the steam pipe 6 and the sliding hole 10, the up-and-down reciprocating motion of the driving cylinder 4 is realized, so as to continuously shake the plants up and down.

[0040] In this embodiment, correspondingly, a placement opening is provided at the top of the driving cylinder 4, and a cover plate 19 is provided on the placement opening.

Since the cam 18 is located above the cover plate 19, when the cover plate 19 needs to be disassembled, the electric cylinder 22 is used to stretch the driving frame 23 outwards, so that the driving frame 23 pulls the sleeve 20 towards the motor 30. The sleeve 20 drives the cam 18 to approach the motor 30, thereby moving away from the cover plate 19, facilitating the disassembly of the cover plate 19. Through the hexagonal design of the driving shaft 21 and the hexagonal through groove design inside the sleeve 20, it is convenient to achieve their relative sliding and ensure that the motor 30 can drive the cam 18 to rotate.

[0041] In this embodiment, correspondingly, the distillation tank 1 includes a tank body and a top cover 24 provided at the top of the tank body.

A bracket 25 is further provided on one side of the distillation tank 1. The cooling device 29 is installed on the bracket 25. One end of the connecting pipe 26 is rotatably connected to the bracket 25, and the output end of the connecting pipe 15 penetrates the bracket 25 and is rotatably connected to the top end of the cooling device 29. The other end of the connecting pipe 26 is connected to the top output end of the top cover 24 through a telescopic pipe 27. Among them, the connecting pipe 15 is a rigid pipeline. When the top cover 24 is disassembled, by rotatably connecting the connecting pipe 15 to the bracket 25, the top cover 24 can be rotated to a position deviating from the top of the distillation tank 1. Through the setting of the telescopic pipe 27, it is convenient for the top cover 24 to be detached from and fastened to the top of the distillation tank 1.

[0042] In summary, when using this efficient essential oil extraction device, first connect the water supply pipe 12 and the connecting pipe 15 of the cooling device 29 to an external water source to ensure that there is enough water inside the placement cavity 7. Then remove the top cover 24, open the top of the distillation tank 1, and at the same time turn on the electric cylinder 22 to contract the cam 18 towards the motor 30. Remove the cover plate 19, place the plants in the gap between the driving cylinder 4 and the steam pipe 6, then install the cover plate 19 and at the same time install the top cover 24. Turn on the heating device 2 and the motor 30. The heating device 2 heats the water in the placement cavity 7 to generate steam. The steam is transported through the steam pipe 6 into the driving cylinder 4. The electric rotation makes the plants move up and down. The steam fully contacts the plants through the exhaust holes 8 and discharges the essential oil steam in the plants together through several through holes 9 on the driving cylinder 4 and rises. It is transported through the top cover 24 and the connecting pipe 26 to the cooling device 29 for condensation. The condensed water is transported through the discharge pipe 28 to the static collection tank 3 for static stratification. Finally, after discharging the water on the lower side, the essential oil on the upper layer is finally left and collected. It should be noted that the installation positions between the motor 30 and the electric cylinder 22 and the side wall of the distillation tank 1 are all sealed.
