Description

Technical Field

[0001] This utility model relates to the technical field of citrus essential oil production equipment, specifically to an oil-water separation device for citrus essential oil extraction. Background Technology

[0002] Citrus essential oil is a high-quality raw material for food, cosmetics, and perfume ingredients. In the industrial production of citrus essential oil, the citrus fruit is first processed using a needle-punching citrus oil mill. Specifically, this mill uses a combination of high-speed rotating needles and a feeding scraper to effectively puncture and separate the citrus peel into fragments. High-pressure water is then used to wash away the citrus oil and the fragments, collecting them in a collection tank. The fragments are then filtered out from the mixture of water, fragments, and citrus oil. Finally, the water and citrus oil are separated to obtain highly pure citrus essential oil.

[0003] In practice, it was found that a significant amount of citrus oil remained in the initially separated pulp, and discarding it directly would be wasteful. Furthermore, the process of filtering the pulp first and then separating the water and citrus oil, which involves two separate steps, still has room for optimization. Utility Model Content

[0062] See Figures 1 to 8 This embodiment provides an oil-water separation device for citrus essential oil extraction, including a frame 10, a separation cylinder 20, a sealing plate 30, a feed rod 40, a drive mechanism, and a separation component 50.

[0063] The separator 20 is horizontally fixed on the frame 10. One end of the separator 20 is an open slag discharge end 21, and the inner wall of the slag discharge end 21 is conical. Specifically, the axis of the separator sleeve is parallel to the horizontal plane. The closer the slag discharge end 21 of the separator sleeve is to the end, the smaller the inner diameter of the inner wall, and the overall shape is conical. The sealing plate 30 is fixedly connected to the end of the separator 20 away from the slag discharge end 21. The sealing plate 30 has a first mounting hole 31 coaxial with the separator 20, as well as an oil outlet hole 32 and a water outlet hole 33. The feed rod 40 is rotatably mounted on the frame 10. One end of the feed rod 40 has a coaxial feed hole 41, and the other end of the feed rod 40 passes through the first mounting hole 31 and is located inside the slag discharge end 21. The feed rod 40 and the first mounting hole 31 are dynamically sealed. The middle part of the feed rod 40 has a discharge hole 42 communicating with the feed hole 41. The drive mechanism is used to drive the feed rod 40 to rotate. Specifically, the drive mechanism may include two pulleys and a motor 76. One pulley is sleeved on the feed rod 40, and the other pulley is rotatably mounted on the frame 10 and connected to the output rod of the motor 76. The two pulleys are connected by a belt.

[0064] With the help of the rotation of the feed rod 40, the separation component 50 separates and conveys the broken skin and slag in the mixture that enters the separation cylinder 20 after passing through the feed hole 41 and the discharge hole 42 to the slag outlet 21, separates and conveys the water in the mixture to the oil outlet 32, and separates and conveys the oil in the mixture to the water outlet 33.

[0065] In this embodiment, the mixture includes water, citrus oil, and pulp residue. The mixture is fed into the separator 20 through the feed hole 41 of the feed rod 40 and discharged into the separator 20 through the discharge hole 42. With the rotation of the feed rod 40, the separation mechanism conveys water and oil to one side of the sealing plate 30 and conveys the pulp residue to the discharge end 21, achieving separation of the three components in one step. At the discharge end 21, because the inner wall of the discharge end 21 is conical, as the pulp residue moves axially along the separator 20 towards the discharge end 21, it is subjected to compression by the inner wall of the separator 20 and the feed rod 40, thus pressing the pulp residue. The citrus oil obtained through pressing flows back to the middle of the separator 20 due to the conical inner wall of the discharge end 21, thereby improving the utilization rate of the pulp residue and reducing waste.

[0066] In one embodiment, the separation assembly 50 includes a first helical blade 51. The helical blade extends from the middle of the separation cylinder 20 toward the slag discharge end 21 of the separation cylinder 20, and the inner side of the first helical blade 51 is connected to the outer wall of the feed rod 40. The outer side of the first helical blade 51 is adapted to the inner wall of the separation cylinder 20. A second mounting hole 43 is provided at the end of the feed rod 40 away from the sealing plate 30, and a plurality of third mounting holes 44 communicating with the second mounting hole 43 are provided on the side wall of the feed rod 40.

[0067] The oil-water separation device also includes multiple extrusion columns 60 and an extrusion power mechanism 70.

[0068] The extrusion column 60 is slidably disposed within the corresponding third mounting hole 44, and the extrusion column 60 and the third mounting hole 44 are dynamically sealed. All extrusion columns 60 are located within the slag discharge end 21, and the outer end of the extrusion column 60 can protrude from the outer wall of the feed rod 40. The extrusion power mechanism 70 is used to drive multiple extrusion columns 60 to extend from the third mounting hole 44 to extrude the broken slag within the slag discharge end 21.

[0069] In this embodiment, after the first spiral blade 51 is connected to the feed rod 40, it can rotate with the feed rod 40, thereby conveying the broken peel residue separated by the separation component 50 to the residue outlet 21. Driven by the extrusion power mechanism 70, multiple extrusion columns 60 can extend from the third mounting hole 44 to further press the broken peel residue in the space enclosed by the first spiral blade 51, the feed rod 40, and the separation cylinder 20, so that the citrus oil in the broken peel residue is pressed out and flows back to the middle of the separation cylinder 20.

[0070] In one embodiment, a coaxial fourth mounting hole 45 is provided at the bottom of the second mounting hole 43.

[0071] The extrusion power mechanism 70 also includes a drive rod 71, a limiting ring 72, a first spring 73, and a conical block 74.

[0072] The drive rod 71 is rotatable, and one end of the drive rod 71 passes through the second mounting hole 43 and is threadedly connected to the fourth mounting hole 45. Multiple limiting rings 72 are provided, each fitting around the corresponding extrusion column 60 and located within the second mounting hole 43. Multiple first springs 73 are provided, each fitting around the extrusion column 60, with one end abutting against the inner wall of the second mounting hole 43 and the other end abutting against the limiting ring 72. Multiple conical blocks 74 are provided, coaxially and fixedly connected to the feed rod 40, and the outer conical surface of the conical block 74 abuts against the inner end of the corresponding extrusion column 60.

[0073] In this embodiment, the end of the drive rod 71 is threadedly connected to the fourth mounting hole 45, which causes the drive rod 71 to rotate and move axially along the fourth mounting hole 45, thereby driving the conical block 74 to move, and then pushing the multiple extrusion columns 60 so that the outer ends of the extrusion columns 60 extrude the scrap. When the conical block 74 disengages from the end of the extrusion column 60, under the action of the first spring 73, the inner end of the extrusion column 60 abuts against the outer wall of the feed rod 40. At this time, the outer end of the extrusion column 60 retracts into the third mounting hole 44 and no longer extrudes the scrap. Meanwhile, the first spiral blade 51 continuously conveys the scrap. When different scraps pass through the extrusion column 60, the extrusion column 60 extends outward again to extrude.

[0074] In one embodiment, the slag discharge end 21 of the separator 20 is connected to a coaxial mounting sleeve 22; a mounting bracket 23 is connected to the mounting sleeve 22; and an inwardly contracting sealing ring 46 is provided at the opening of the second mounting hole 43. The inner ring of the sealing ring 46 dynamically seals with the drive rod 71; a square hole 711 is provided at the end of the drive rod 71 away from the fourth mounting hole 45.

[0075] The extrusion power mechanism 70 also includes an extrusion disc 75, a motor 76, and a square rod 77.

[0076] The extrusion disc 75 is coaxially and fixedly connected to the drive rod 71, and the extrusion disc 75 can be moved into the mounting sleeve 22. The motor 76 is fixedly connected to the mounting bracket 23. One end of the square rod 77 is fixedly connected to the output end of the motor 76, and the other end of the square rod 77 is slidably inserted into the square hole 711. The square rod 77 is adapted to the square hole 711.

[0077] Driven by the motor 76, the square rod 77 rotates the drive rod 71, which can slide on the square rod 77. The extrusion disc 75 moves into the mounting sleeve 22 along with the drive rod 71, and can work with the first spiral blade 51 and the extrusion column 60 to extrude the scrap inside the mounting sleeve 22. Due to the presence of the sealing ring 46, the scrap will not enter the second mounting hole 43.

[0078] In one embodiment, the extrusion power mechanism 70 further includes multiple extrusion blocks 78; the extrusion blocks 78 are fixedly connected to the side of the extrusion disc 75 facing the feed rod 40; the multiple extrusion blocks 78 are arranged in a ring; the side of the extrusion blocks 78 facing the feed rod 40 is an inclined surface.

[0079] In this embodiment, the extrusion block 78 enters the mounting sleeve 22 together with the extrusion disc 75 to extrude the broken skin residue. When the extrusion disc 75 rotates, the inclined surface of the extrusion block 78 contacts the broken skin residue and extrudes it.

[0080] In one embodiment, the extrusion disc 75 has a through transition hole 84. The extrusion power mechanism 70 also includes a retaining ring 79, a baffle 80, a second spring 81, a discharge plate 82, and a connecting rod 83.

[0081] The retaining ring 79 is fixedly connected to the mounting bracket 23 and slidably sleeved on the drive rod 71. The baffle 80 is slidably sleeved on the drive rod 71 through an opening, and one end of the baffle 80 can abut against the retaining ring 79. The second spring 81 is sleeved on the drive rod 71, one end of the second spring 81 abuts against the baffle 80, and the other end of the second spring 81 abuts against the side of the extrusion plate 75 opposite to the feed rod 40. The blanking plate 82 is slidably sleeved on the drive rod 71 through an opening, and the blanking plate 82 is located between multiple extrusion blocks 78. The outer end of the blanking plate 82 can also extend between adjacent extrusion blocks 78. One end of the connecting rod 83 is connected to the baffle 80, and the other end of the connecting rod 83 passes through the transition hole 84 and is fixedly connected to the blanking plate 82.

[0082] In this embodiment, the space between the extrusion block 78 and the extrusion disc 75 can easily cause a large amount of scrap to get stuck there when extruding the scrap. When the extrusion disc 75 finishes extruding and moves away from the feed rod 40, the baffle 80 moves and abuts against the retaining ring 79, thereby causing the connecting rod 83 to drive the discharge plate 82 to move relative to the extrusion plate, pushing out the scrap stuck on the extrusion block 78 and the extrusion disc 75.

[0083] In one embodiment, the separation assembly 50 further includes a plurality of propeller blades 52 connected to the outer wall of the feed rod 40. The propeller blades 52 rotate with the feed rod 40, agitating the mixture flowing out of the discharge hole 42, so that the mixture rotates around the axis of the separation cylinder 20 and moves toward the sealing plate 30. The distance between the oil outlet 32 ​​and the axis of the separation cylinder 20 is less than the distance between the water outlet 33 and the axis of the separation cylinder 20. Specifically, multiple pairs of propeller blades 52 may be provided, and the multiple pairs of propeller blades 52 are arranged along the axial direction of the feed rod 40. The discharge hole 42 is located between the multiple pairs of propeller blades 52.

[0084] In this embodiment, the mixture enters the separator 20 through the discharge port 42. As the feed rod 40 rotates, it drives the propeller blade 52 to rotate, thereby causing the mixture to rotate and be pushed towards the sealing plate 30. The lighter citrus oil is closer to the feed rod 40 during centrifugation, while the heavier peel residue is closer to the wall of the separator 20. Water is located between the peel residue and the citrus oil. The citrus oil is discharged through the oil outlet 32, and the water is discharged through the water outlet 33.

[0085] In one embodiment, the separation assembly 50 further includes a second helical blade 53; the width of the second helical blade 53 is smaller than the width of the first helical blade 51; one end of the second helical blade 53 is fixedly connected to the end of the first helical blade 51 away from the slag discharge end 21, and the other end of the second helical blade 53 extends helically along the axial direction of the separation cylinder 20 toward the sealing plate 30; the second helical blade 53 is located outside the propeller blade 52. The second helical blade 53 is adapted to the inner wall of the separation cylinder 20; specifically, there is only a small gap between the outer side of the second helical blade 53 and the inner wall of the separation cylinder 20.

[0086] In this embodiment, when the propeller blade 52 rotates and drives the mixture to rotate and centrifuge, the broken skin residue is located on the wall of the separation cylinder 20. When the feed rod 40 rotates, it drives the first spiral blade 51 and the second spiral blade 53 in sequence. The second spiral blade 53 transports the broken skin residue on the wall of the separation cylinder 20 to the first spiral blade 51.

[0087] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
