Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plant volatile oil extraction, and in particular to a plant volatile oil extraction device. BACKGROUND

[0002] Plant volatile oil, also known as volatile oil, is a general term for volatile oil components that are incompatible with water and are distilled from materials. Distillation extraction can be divided into water-separation distillation and water-supply distillation. The volatile oil remaining in the material after distillation cannot be collected well.

[0003] For example, the patent with publication number CN205258424U discloses a distillation extraction tank for extracting plant volatile oil, which comprises a tank body, a steam outlet is arranged at the top end of the tank body, a cover is hingedly connected to the top of the tank body, a material basket with a porous bottom is arranged in the tank body, a water supply cavity is formed between the side wall and the bottom of the material basket and the inner wall and the bottom of the tank body, and the top of the water supply cavity is sealed. Although the distillation extraction tank can be used for water-separation distillation and water-supply distillation by adding the material basket, the material subjected to water-supply distillation cannot be separated from the volatile oil after distillation, and the separated material still contains volatile oil, which is not collected and thus wasted.

[0043] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0044] This invention discloses a plant volatile oil extraction device.

[0045] like Figure 1 As shown, a plant volatile oil extraction device in this embodiment includes a fixed box 100, a fixed cavity 201 with an upward opening inside the fixed box 100, a movable collection cylinder 210 inside the fixed cavity 201, a collection chamber 401 for placing materials inside the collection cylinder 210 along its length direction, opposite sliding grooves 202 respectively provided on opposite side walls of the fixed cavity 201 along the height direction of the fixed cavity 201, each sliding groove 202 is provided with a lifting component for driving the two ends of the collection cylinder 210 to rise and fall, a fixed rod 410 with both ends extending out of the corresponding ends of the collection chamber 401 inside the collection chamber 401, a squeezing component for squeezing the material in the collection chamber 401 on the fixed rod 410, and a driving component for driving the fixed rod 410 to rotate and drive the collection cylinder 210 to rotate on the outer side wall of the fixed box 100.

[0046] In this embodiment, the collecting cylinder 210 is rotatably mounted on the lifting assembly via the fixing rod 410. The lifting assembly raises the collecting cylinder 210 to the opening of the fixed cavity 201, and the material is placed in the collecting cavity 401. Then, the lifting assembly lowers the collecting cylinder 210 to the bottom of the fixed cavity 201. By adding an appropriate amount of water to the fixed cavity 201 and heating the water, the volatile oil in the material is extracted.

[0047] The side wall of the collecting cylinder 210 is evenly provided with multiple through holes that connect to the collecting chamber 401. Water in the fixed chamber 201 enters the collecting chamber 401 through the through holes to distill the material. The particle size of the material is larger than the diameter of the through holes, so that the material is always kept in the collecting chamber 401. When the collecting cylinder 210 rises, it can drive the material in the collecting chamber 401 to rise, thereby achieving the separation of the material from the volatile oil.

[0048] A heating rod (not shown in the figure) is installed on the bottom wall of the fixed cavity 201. The water is heated by the heating rod to distill the material in the collection cylinder 210.

[0049] The fixed box 100 has a slot 204 on its side wall that connects to the fixed cavity 201. The fixed cavity 201 has a slot 203 on its side wall corresponding to the slot 204. A cover plate 150 is provided between the slot 204 and the slot 203 to seal the opening of the fixed cavity 201. The cover plate 150 can be inserted into the slot 204 and one end overlaps the slot 203 through the slot 204 and the slot 203. When the material is distilled, the cover plate 150 seals the opening of the fixed cavity 201, thereby improving the distillation efficiency of the material. A pull hole 151 is provided at one end of the cover plate 150, which allows the staff to easily pull the cover plate 150 to move it.

[0050] After distillation is completed, the collecting cylinder 210 is raised to the upper end of the fixed cavity 201 by the lifting assembly, so that the collecting cylinder 210 is above the liquid surface of the volatile oil in the fixed cavity 201. The material in the collecting cavity 401 is squeezed by the squeezing assembly installed on the fixed rod 410, so that the residual volatile oil in the material can be squeezed out and collected into the fixed cavity 201.

[0051] The drive component is designed so that when the extrusion component is extruding the material, the drive component is connected and drives the fixed rod 410 to rotate. At the same time, the collection cylinder 210 is rotated, and the unextruded volatile oil in the collection cylinder 210 is centrifuged out and collected into the fixed cavity 201, thereby reducing the residue of volatile oil in the material after distillation and reducing waste.

[0052] The fixed box 100 has a discharge pipe 140 connected to the fixed cavity 201 on its outer side wall. The discharge pipe 140 is equipped with a cover 141 for sealing the discharge pipe 140. By opening the cover 141, the volatile oil collected in the fixed cavity 201 can be discharged. After discharge, oil-water separation can be performed to obtain pure volatile oil. After discharge, the cover 141 is used to seal the discharge pipe 140.

[0053] like Figure 8 As shown, in this embodiment, the side wall of the collecting cylinder 210 is provided with a connecting groove 801 that connects to the collecting cavity 401. The side wall of the connecting groove 801 is provided with a pull-out groove 802. The pull-out groove 802 is provided with a movable pull-out plate 810. The other side wall of the connecting groove 801 is provided with a limiting groove 803 into which one end of the pull-out plate 810 extends. The side wall of the collecting cylinder 210 is provided with a bolt 811 that passes through the limiting groove 803 to fix the pull-out plate 810 at the position corresponding to the limiting groove 803.

[0054] In this embodiment, the arrangement of the connecting groove 801, the pull-out groove 802, the pull-out plate 810, the limiting groove 803, and the bolt 811 allows the pull-out plate 810 to slide along the pull-out groove 802. When one end of the pull-out plate 810 extends into the limiting groove 803, the pull-out plate 810 blocks the connecting groove 801. The bolt 811 is threaded through the side wall of the collecting cylinder 210 and fixed to the pull-out plate 810, so that the pull-out plate 810 can maintain the blockage of the connecting groove 801, thereby preventing material from flowing out of the connecting groove 801 into the fixing cavity 201.

[0055] Specifically, by unscrewing the bolt 811, the pull plate 810 is slid into the pull groove 802, thereby opening the connecting groove 801. At this time, the material can be placed into the collection chamber 401 through the connecting groove 801. After completion, the connecting groove 801 is closed by pulling the pull plate 810.

[0056] like Figures 1-5 As shown, in this embodiment, the upper end of the fixed box 100 is provided with mounting blocks 110 at the positions corresponding to the slide grooves 202, and the mounting blocks 110 are provided with mounting grooves 501 that communicate with the corresponding slide grooves 202.

[0057] The lifting assembly includes a gear 220 disposed in the mounting groove 501. A drive rod 120 with both ends passing through the corresponding gear 220 and rotatable is disposed between two mounting blocks 110. A rack 230 is disposed in the mounting groove 501, meshing with the corresponding gear 220 and with its lower end extending into the slide groove 202. A connecting rod 300 is disposed on the lower end surface of the rack 230. A connecting block 310 is disposed at the lower end of the connecting rod 300. The two ends of the fixing rod 410 are respectively rotatably mounted on the corresponding connecting block 310. The rotation of the drive rod 120 drives the gear 220 to rotate, thereby driving the rack 230 to lift and lower. This enables the fixing rod 410 on the connecting block 310 to drive the collecting cylinder 210 to lift and lower. A locking element is disposed on the mounting block 110 to lock the rotation of the drive rod 120.

[0058] In this embodiment, the mounting block 110, mounting groove 501, gear 220, drive rod 120, rack 230, connecting rod 300, connecting block 310, and locking element are arranged such that two gears 220 are fixedly mounted on the drive rod 120, so that the rotation of the drive rod 120 can synchronously drive the two gears 220 to rotate, causing the two racks 230 to rise or fall simultaneously. At the same time, the connecting rod 300 and connecting block 310, which are fixedly mounted under the gears 220, can be raised or lowered, thereby driving the collection cylinder 210 installed between the two connecting blocks 310 to rise or fall. In order to achieve stable raising and lowering of the rack 230, the shape of the rack 230 is adapted to the mounting groove 501.

[0059] A locking block 340 is fixedly installed at the lower end of the rack 230. The mounting block 110 has a positioning groove 351 on the side wall corresponding to the locking block 340 for the locking block 340 to slide. With the setting of the locking block 340 and the positioning groove 351, after the gear 220 drives the rack 230 to rise to a certain height, the locking block 340 abuts against the end of the positioning groove 351, so that the locking block 340 cannot move, thereby preventing the rack 230 from sliding out of the mounting groove 501.

[0060] In actual use, when the distillation of the material is completed, the collection cylinder 210 is raised by rotating the drive rod 120. When it rises to the appropriate position, the drive rod 120 needs to be locked by the locking device so that the drive rod 120 cannot rotate, thereby enabling the collection cylinder 210 to maintain the height after rising.

[0061] like Figures 1-4 As shown, in this embodiment, a slot 502 is provided on the side wall of the mounting block 110;

[0062] The locking component includes a disc 240 disposed on the extended end of the drive rod 120. A limiting rod 250 is provided at the corresponding position of the slot 502, which passes through the disc 240 and is movable. The limiting rod 250 extends into the slot 502 to lock the drive rod 120.

[0063] In this embodiment, by setting up the slot 502, the disc 240 and the limiting rod 250, when the drive rod 120 rotates and raises the collection tube 210 to a suitable height, the limiting rod 250 is inserted into the slot 502, which can lock the rotation of the drive rod 120 and prevent the drive rod 120 from rotating.

[0064] The disc 240 is provided with a rotating hole for the limiting rod 250 to pass through. A collar 460 is fixed on the limiting rod 250 located between the disc 240 and the mounting block 110. By installing the collar 460 and the retaining ring located at the outer end of the limiting rod 250, the limiting rod 250 is prevented from detaching from the disc 240, thereby affecting the locking of the drive rod 120.

[0065] In actual use, the staff can drive the rod 120 to rotate by using the limit rod 250, making the rotation of the rod 120 more convenient.

[0066] like Figures 1-6 As shown, in this embodiment, the upper end of the fixing box 100 is provided with a through threaded hole 441 corresponding to the other end of the fixing rod 410. The threaded hole 441 is provided with a threaded screw 260. The fixing rod 410 is provided with an installation cavity 411 with openings at both ends for the screw 260 to be inserted. The side wall of the fixing rod 410 is provided with a through groove 601 that communicates with the installation cavity 411.

[0067] The extrusion assembly includes a movable rod 420 located in the mounting cavity 411. Two positioning blocks 421 protruding from the through slot 601 are provided on the movable rod 420. A movable pressure plate 430 is sleeved outside the fixed rod 410 and located between the two positioning blocks 421. The screw 260 extends into the mounting cavity 411 to push the movable rod 420 to move and drive the pressure plate 430 to extrude the material in the collection cavity 401.

[0068] In this embodiment, by setting up the threaded hole 441, screw 260, mounting cavity 411, through groove 601, movable rod 420, through groove 601, positioning block 421 and pressure plate 430, the center of the end of the collecting cylinder 210 is raised to the threaded hole 441, the screw 260 is inserted into the mounting cavity 411 and the movable rod 420 is pushed to slide along the mounting cavity 411, thereby driving the positioning block 421 to move along the through groove 601, and at the same time pushing the pressure plate 430 to move, so as to squeeze the material in the collecting cavity 401 and initially squeeze out the volatile oil contained in the material.

[0069] The threaded fit between the screw 260 and the threaded hole 441 ensures that when the screw 260 moves into the mounting cavity 411, it can always push the movable rod 420 to move, so that the pressure plate 430 can always maintain the extrusion of the material.

[0070] In actual use, the outer wall of the pressure plate 430 slides against the inner wall of the collection cylinder 210. By installing the pressure plate 430 between two positioning blocks 421, the two positioning blocks 421 limit the pressure plate 430, so that the pressure plate 430 can always be kept vertical and installed in the collection cylinder 210. At the same time, the movement of the movable rod 420 enables the pressure plate 430 to have a better squeezing effect on the material.

[0071] like Figures 1-8 As shown, in this embodiment, the end of the movable rod 420 away from the screw 260 is provided with a first ratchet 611, and the fixed box 100 is provided with a mounting hole 442 at the position corresponding to the threaded hole 441.

[0072] The drive assembly includes a motor 130 mounted on the outer wall of the fixed box 100. The output shaft 700 of the motor 130 extends into the mounting hole 442. The output shaft 700 has a circular groove 701 along its length. The side wall of the circular groove 701 has a recess 702 with one end open. A movable rod 710 with one end protruding is provided in the circular groove 701. The side wall of the movable rod 710 has a protrusion 711 that engages with the recess 702. The end of the movable rod 710 has a second ratchet 712 that meshes with the first ratchet 611. The screw 260 pushes the movable rod 420 to move, causing the first ratchet 611 on the movable rod 420 to mesh with the second ratchet 712 on the movable rod 710, so that the output shaft 700 of the motor 130 drives the movable rod 420 to rotate, thereby causing the collecting cylinder 210 to rotate.

[0073] In this embodiment, the arrangement of the first ratchet 611, mounting hole 442, motor 130, output shaft 700, circular groove 701, groove 702, moving rod 710, protrusion 711, and second ratchet 712 enables the first ratchet 611 on the movable rod 420 to mesh with the second ratchet 712 on the moving rod 710, allowing the motor 130 to drive the movable rod 420 to rotate. The positioning block 421 on the movable rod 420 drives the fixed rod 410 to rotate, thereby realizing the rotation of the collecting cylinder 210. The volatile oil that has not been squeezed out in the material is centrifuged out and collected into the fixed cavity 201.

[0074] When the screw 260 pushes the movable rod 420 to move, the first ratchet 611 on the movable rod 420 abuts against the second ratchet 712 on the moving rod 710, thereby enabling the movable rod 420 to drive the moving rod 710 to rotate.

[0075] The circular groove 701 allows one end of the moving rod 710 to extend into the groove 702, enabling the moving rod 710 to be installed in the circular groove 701. The groove 702 and the protrusion 711 allow the output shaft 700 of the motor 130 to rotate, which in turn drives the moving rod 710 to rotate, thereby causing the movable rod 420, which meshes with the moving rod 710, to rotate.

[0076] Among them, a shim 720 is installed between the movable rod 710 and the circular groove 701. The installation of the shim 720 allows the movable rod 710 to deform when it engages with the movable rod 420, so that the movable rod 710 can better engage with the movable rod 420.

[0077] In actual use, a plugging ring 730 is threadedly installed at the opening of the circular groove 701. The plugging ring 730 blocks the protrusion 711, thereby preventing the moving rod 710 from sliding out of the circular groove 701.

[0078] In this embodiment, a spring 450 is sleeved on the fixing rod 410 located between the side wall of the pressure plate 430 facing the screw 260 and the end wall of the collection cavity 401. The two ends of the spring 450 are respectively fixedly installed at the bottom wall of the collection cavity 401 and the end of the pressure plate 430, so that when the screw 260 moves out of the mounting cavity 411, the spring 450 is used to pull the disc 240 closer to the side wall of the collection cavity 401, so that the pressure plate 430 is reset and the movable rod 420 is reset at the same time. At this time, the engagement between the movable rod 420 and the moving rod 710 is released.

[0079] Working principle: First, the connecting groove 801 is opened by sliding the pull plate 810, and the material is placed in the collecting chamber 401. Then, the connecting groove 801 is closed by sliding the pull plate 810. At this time, an appropriate amount of water is added to the fixed chamber 201, and heating is carried out by the heating rod. The opening of the fixed chamber 201 is sealed by the cover plate 150 to achieve distillation of the material. After distillation is completed, the collecting cylinder 210 is raised to a certain height by the lifting component, and the material is separated from the volatile oil. By rotating the screw 260, one end of the screw 260 is inserted into the mounting chamber 411 and pushed to squeeze. The component squeezes the material in the collection chamber 401, collecting the residual volatile oil in the material into the fixed chamber 201. At this time, the movable rod 420 is connected to the drive component, and the drive movable rod 420 rotates to drive the collection cylinder 210 to rotate, centrifugally discharging the volatile oil that has not been squeezed out of the material and collecting it into the fixed chamber 201. After completion, the cover 141 is opened to discharge the volatile oil in the fixed chamber 201 through the discharge pipe 140, and then oil-water separation is performed. Finally, the cover plate 150 is slid to open the fixed chamber 201, and the material can be taken out by opening the connecting groove 801.
