Description

Technical Field

[0001] This invention belongs to the field of soybean oil production and application technology, and more specifically, it relates to an extraction apparatus for soybean oil production. Background Technology

[0002] In soybean oil production, the leaching and condensation unit is a key piece of equipment in the solvent recovery process. After the leaching process extracts oil using organic solvents (such as n-hexane), the soybean germ needs to be recovered for feed processing to reduce production costs.

[0003] Patent CN117815701B discloses an extraction apparatus for soybean oil production. It includes an extractor shell and an extraction cylinder housed within the shell. The extraction cylinder contains several extraction compartments, and a rotating gear ring is fitted onto its outer wall. A drive motor reducer is located on the outer side of the extractor shell. While this patent solves the problem of extracting and agitating soybean germ without adding a power mechanism, a separation device is still required to separate the solid and liquid components from the extracted soybean germ. Therefore, additional mechanisms are needed to meet the separation requirements.

[0004] To address the aforementioned technical problems, this application proposes a solution. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an extraction device for soybean oil production. This device can improve the extraction effect of soybean germ and squeeze the liquid in the soybean germ to recover the soybean germ.

[0006] The aforementioned leaching and extraction device for soybean oil production includes a base mechanism, a lifting mechanism, and a filtering mechanism. The base mechanism comprises a base, with a cylindrical barrel fixedly connected to one upper end. A hollow cylinder is fixedly connected to the center of the barrel's interior. A limiting base is fixedly connected to the top of the hollow cylinder. Four elongated grooves are formed around the hollow cylinder. Four protruding strips are evenly fixedly connected to the bottom of the barrel's interior. An oil outlet hole is formed at the bottom of the barrel's interior. Multiple slide rails are fixedly connected to the upper outer perimeter of the barrel. Two supports, L-shaped, are fixedly connected to the barrel at the bottom of each slide rail, located on opposite sides of the barrel. A shaft hole is formed at the long end of each support.

The spring is nested on the outside of the shaft. A single tooth is fixedly connected to one end of the spring, and the single tooth is slidably connected to the shaft.

[0008] Preferably, a ring seat is fixedly connected to the outer side of the upper end of the hollow cylinder, and eight fan plates in two layers are rotatably connected around the ring seat. The eight fan plates together form a circle. A second hanging ring is fixedly connected above the outer arc of the fan plate, and a rope is fixedly connected to the second hanging ring. The rope passes through the through hole and is fixedly connected to the first hanging ring.

[0009] Preferably, the filtration mechanism includes a rack column, which is slidably connected to a limiting base. A frustum is fixedly connected to the bottom of the rack column. The frustum is slidably connected to a hollow cylinder, and the diameter of the frustum is the same as the inner diameter of the hollow cylinder. Four cylinders are fixedly connected around the frustum. The cylinders are slidably connected to a long groove. A sieve basin is fixedly connected to one end of each cylinder. The sieve basin is slidably connected to a cylindrical barrel, and the outer diameter of the sieve basin is the same as the inner diameter of the cylindrical barrel. Multiple sieve holes are opened around the sieve basin and at the bottom. A plate groove is opened at the bottom of the sieve basin. Multiple hemispherical grooves are opened on both sides inside the four long ends of the plate groove. A lifting plate is slidably connected to the plate groove, and one end of the lifting plate is flush with the bottom of the sieve basin.

[0010] Preferably, the lifting plate has multiple slots on its four long ends, and a second spring is installed in each slot. A steel ball is fixedly connected to both ends of the second spring. The steel ball passes through the lifting plate and abuts against the hemispherical slot. A fixing plate is fixedly connected to one side of the four long ends of the lifting plate. Multiple protrusions are fixedly connected to the side of the fixing plate that contacts the lifting plate. The protrusions enter the slots and abut against the second spring. A ring plate is provided on one side of the lifting plate and is threadedly connected to the slot.

[0011] Preferably, a horizontal shaft is rotatably connected inside the shaft hole, gears are fixedly connected to the middle and both ends of the horizontal shaft, a gearbox is fixedly connected to the base, one end of the horizontal shaft is rotatably connected to the gearbox, a drive device is fixedly connected to the base on one side of the gearbox, and the extended end of the drive device is rotatably connected to the gearbox.

[0012] Preferably, the horizontal shaft is rotatably connected to the limiting base, the gear in the middle of the horizontal shaft meshes with the rack column for transmission, the horizontal shaft and the rack column are perpendicular to each other, the gears at both ends of the horizontal shaft pass through the upright and mesh with the tooth plate for transmission, and the meshing points of the middle gear with the rack column and the meshing points of the gears at both ends with the tooth plate are located on both sides of the horizontal shaft.

[0013] Preferably, an oil drain pipe is fixedly connected to the bottom of the oil outlet, a solenoid valve is fixedly connected to the oil drain pipe, and an oil inlet and a feed inlet are sealed at the top of the barrel.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention uses a power source to fully mix soybean germ with n-hexane solvent. By rotating the horizontal shaft, the gear in the middle of the horizontal shaft drives the filtering mechanism to move up and down, and the soybean germ in the sieve basin begins to move up and down. The gears on both sides of the horizontal shaft drive the lifting mechanism to move up and down. During this stroke, the gears on both sides of the horizontal shaft only mesh with the toothed plate for transmission. While the lifting mechanism moves up and down, it also drives the fan plate inside the cylinder to move up and down, stirring the liquid so that the soybean germ is fully mixed in the n-hexane solvent, and the oil in the soybean germ is fully dissolved into the n-hexane solvent.

[0016] 2. In the solid-liquid separation of soybean germ and liquid, the present invention only needs to drive the lifting mechanism downward by the gears on both sides of the horizontal shaft. The rope connected to the lifting mechanism will open the fan plate. When the fan plate is fully opened, the gears on both sides of the horizontal shaft engage with the single tooth on the tooth plate, causing the lifting mechanism to stop moving downward. At the same time, the gear in the middle of the horizontal shaft meshes with the rack column, continuously moving the screen bowl upward. The screen bowl and the fan plate work together to pressurize the soybean germ in the middle, thus performing solid-liquid separation.

[0017] 3. The present invention also makes it easy to remove soybean embryos. Simply move the squeezed soybean embryos along with the sieve basin downwards, so that the convex strips push the lifting plate upwards. The shaped soybean embryos located on the upper part of the lifting plate can then be removed from the sieve basin.

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] like Figures 1 to 10As shown, a soybean oil extraction device includes a base mechanism 1, a lifting mechanism 5, and a filtering mechanism 7. The base mechanism 1 includes a base 101, which provides support. A cylindrical barrel 102 is fixedly connected to one end of the upper part of the base 101. The interior of the cylindrical barrel 102 is the main site for the extraction of soybean germ. A hollow cylinder 104 is fixedly connected to the middle of the interior of the cylindrical barrel 102. A limiting base 112 is fixedly connected to the top of the hollow cylinder 104. Four long grooves 1041 are formed around the hollow cylinder 104. Four protrusions 105 are evenly fixedly connected to the bottom of the inner part of the cylindrical barrel 102. An oil outlet hole 103 is formed at the bottom of the inner part of the cylindrical barrel 102. Multiple slide rails 107 are fixedly connected to the upper and middle parts of the outer side of the cylindrical barrel 102 to limit the lifting mechanism 5 and prevent the lifting mechanism 5 from rotating. The bottom of the slide rail 107 is provided with two brackets 109 that are fixedly connected to the cylinder 102, respectively located on both sides of the cylinder. The brackets 109 are "L" shaped, and the long end of the brackets 109 is provided with a shaft hole 1091. The two sides of the slide rail 107 are fixedly connected with limiters. A through hole 108 is provided on the upper part of the cylinder 102 between each two slide rails 107. A protruding ring 110 is fixedly connected inside the bottom of the cylinder 102 of the through hole 108. An opening 106 is provided on one side of the bottom of the cylinder 102. A door panel 111 that is rotatably connected to the cylinder 102 is provided outside the opening 106.

[0033] like Figures 7 to 8 As shown, the lifting mechanism 5 includes a ring 501. The ring 501 has a number of slide blocks 502 fixedly connected around its circumference, the same number as the slide rail 107. The slide blocks 502 are slidably connected to the slide rail 107, limiting and preventing the ring 501 from rotating. A lifting ring 503 is fixedly connected above the ring 501 between the two slide blocks 502. A support frame 504 is fixedly connected to both sides of the ring 501. The support frame 504 is hollow, with a slot on one side. Two shafts 5044 parallel to the length of the support frame 504 are provided in the slot. A toothed plate 5041 is slidably connected to the outside of the shafts 5044, with the toothed side of the toothed plate 5041 facing inwards. Springs 5042 are fixedly connected to the upper and lower sides of the toothed plate 5041, nested on the outside of the shafts 5044. One end of the spring 5042 is fixed... The horizontal shaft 10 is connected by a single tooth 5043, which is slidably connected to the shaft 5044. The advantage of this design is that the horizontal shaft 10 can rotate continuously. However, when the gears 1001 on both sides of the horizontal shaft 10 move to the ends of the gear plate 5041, they contact the single tooth 5043. Because the spring 5042 controls the extension and retraction of the single tooth 5043, the lifting mechanism 5 does not need to move when the gears 1001 on both sides of the horizontal shaft 10 contact the single teeth 5043 on both sides of the gear plate 5041. Meanwhile, the gear 1001 in the middle of the horizontal shaft 10 can continuously mesh and transmit power to the rack column 701.

[0034] A ring seat 12 is fixedly connected to the outer side of the upper end of the hollow cylinder 104. Eight fan plates 11 in two layers are rotatably connected around the ring seat 12, forming a circle. A second lifting ring 1101 is fixedly connected to the upper part of the outer arc of the fan plate 11. A rope 9 is fixedly connected to the second lifting ring 1101. The rope 9 passes through the through hole 108 and is fixedly connected to the first lifting ring 503. Because the mass of the fan plate 11 is relatively large, the lifting mechanism 5 is affected by gravity when it is above, and the fan plate 11 is folded inside the cylinder 102 without affecting the feeding. When the lifting mechanism 5 is below, the rope 9 connected to the lifting mechanism 5 pulls the fan plate 11 to rotate upward and form a circle.

[0035] like Figure 9 and Figure 10As shown, the filter mechanism 7 includes a rack column 701, one end of which has teeth that mesh with the gear 1001. The rack column 701 is slidably connected to the limiting base 112. The main function of the limiting base 112 is to fix the gear 1001 in the middle of the horizontal shaft 10 and the rack column 701 together, preventing the rack column 701 from being misaligned and not meshing with the gear 1001. A frustum 709 is fixedly connected to the bottom of the rack column 701. A frustum 709 is slidably connected to a hollow cylinder 104, and the diameter of the frustum 709 is the same as the inner diameter of the hollow cylinder 104. The main function of the frustum 709 is to prevent soybean germ from flowing out. Four cylinders 708 are fixedly connected around the frustum 709. The cylinders 708 are slidably connected to a long groove 1041. A sieve basin 702 is fixedly connected to one end of each cylinder 708. The sieve basin 702 is slidably connected to a cylinder 102, and the outer diameter of the sieve basin 702 is the same as the inner diameter of the cylinder 102. Multiple sieve holes 703 are opened around the sieve basin 702 and at the bottom. A plate groove 704 is opened at the bottom of the sieve basin 702. The upper end of the circular part in the middle of the plate groove 704 is sealed, while the long strip ends around it are open from top to bottom. Multiple hemispherical grooves 7041 are opened on both sides inside the four long strip ends of the plate groove 704. A lifting plate 705 is slidably connected to the plate groove 704, and one end of the lifting plate 705 is flush with the bottom of the sieve basin 702. The lifting plate 705 has multiple slots 7051 on its four long ends. Springs 7052 are installed in the slots 7051. Steel balls 7053 are fixedly connected to both ends of springs 7052. The steel balls 7053 pass through the lifting plate 705 and abut against the hemispherical slots 7041. A fixing plate 706 is fixedly connected to one side of the four long ends of the lifting plate 705. Multiple protrusions 7061 are fixedly connected to the side of the fixing plate 706 that contacts the lifting plate 705. The protrusions 7061 enter the slots 7051 and abut against springs 7052. The fixing plate 706 restricts and fixes springs 7052 and steel balls 7053. A ring plate 707 is provided on one side of the lifting plate 705 and is threadedly connected to the slots 704. The function of the ring plate 707 is to fix the lifting plate 705 inside the slots 704. Even when squeezing soybean embryos, the lifting plate 705 will not fall off under pressure. That is, the lifting plate 705 can only extend and retract from one side of the inside of the sieve basin 702. The fixing method of steel ball 7053 and semi-circular groove 7041 ensures that the lifting plate 705 will not move arbitrarily when the screen basin 702 moves up and down to fully mix soybean germ and n-hexane solvent.

[0036] A horizontal shaft 10 is rotatably connected within the shaft hole 1091. Gears 1001 are fixedly connected to the middle and both ends of the horizontal shaft 10. A gearbox 4 is fixedly connected to the base 101. One end of the horizontal shaft 10 is rotatably connected to the gearbox 4. A drive device 3 is fixedly connected to the base 101 on one side of the gearbox 4, and the extended end of the drive device 3 is rotatably connected to the gearbox 4. The drive device 3 used in this invention is a servo motor, which can rotate precisely. The main function of the gearbox 4 in this invention is that the servo motor needs to drive the lifting mechanism 5 and the filtering mechanism 7 to compress the soybean germ at a relatively high pressure. The gearbox 4 can provide high torque without damaging the servo motor.

[0037] The horizontal shaft 10 is rotatably connected to the limiting base 112. The gear 1001 in the middle of the horizontal shaft 10 meshes with the rack column 701 for transmission. The horizontal shaft 10 and the rack column 701 are perpendicular to each other. The gears 1001 at both ends of the horizontal shaft 10 pass through the upright 504 and mesh with the toothed plate 5041 for transmission. The meshing points of the middle gear 1001 and the rack column 701, and the meshing points of the two end gears 1001 and the toothed plate 5041 are located on both sides of the horizontal shaft 10. An oil drain pipe 2 is fixedly connected to the bottom of the oil outlet 103, and a solenoid valve 201 is fixedly connected to the oil drain pipe 2. The oil flow is electrically controlled, reducing manual intervention and ensuring cleanliness. The upper end of the cylindrical drum 102 is sealed with an oil inlet 6 and a feed inlet 8.

[0038] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, the present invention can use numerical control technology or PLC to control the actions of each actuator.

[0039] Working process: Connect the oil inlet 6 and the feed inlet 8 to external pipelines respectively. Initially, the drive unit 3 rotates, driving the horizontal shaft 10 to rotate via the gearbox 4. The three gears 1001 on the horizontal shaft 10 rotate, contacting the lifting mechanism 5 and the filtering mechanism 7 respectively. The gears 1001 on both sides drive the toothed plates 5041 to move upwards, moving the lifting mechanism 5 to the upper end. The rope 9 connected to the lifting mechanism 5, under the influence of the gravity of the fan plates 11, enters the interior of the cylinder 102. Multiple fan plates 11 begin to rotate downwards, shutting off the drive unit 3. Hexane solvent and soybean germ enter from the oil inlet 6 and feed inlet 8 respectively, falling onto the screen basin 702. When the amount of soybeans reaches a certain level, soybean intake stops, while hexane solvent continues to enter until the soybean germ is completely immersed in the hexane solvent, at which point the release of hexane solvent stops.

[0040] Restart the drive unit 3, drive the gears 1001 on both sides of the horizontal shaft 10 to mesh with the toothed plate 5041 and rotate back and forth. The gear 1001 in the middle of the horizontal shaft 10 and the rack column 701 also move up and down back and forth, causing the beans falling on the sieve basin 702 to move up and down. The fan plate 11 rotates up and down (because the fan plate 11 is completely immersed in the n-hexane solvent, there will be no soybean germ residue on the surface of the fan plate 11), which fully mixes the beans and the n-hexane solvent, releasing the oil in the beans into the n-hexane solvent.

[0041] When the oil in the beans is mixed with the hexane solvent, the drive unit 3 drives the gearbox 4 to drive the horizontal shaft 10 to rotate, which moves the filter mechanism 7 upward, the lifting mechanism 5 downward, and the traction rope 9 downward. One end of the rope 9 pulls the fan plate 11 to unfold, so that the upper surface of the fan plate 11 abuts against the convex ring 110. At this time, the gears 1001 at both ends of the horizontal shaft 10 contact the single tooth 5043 on the top of the toothed plate 5041. Under the action of the spring 5042, the single tooth 5043 continuously contacts the gears 1001 at both ends. However, the lifting mechanism 5 no longer continues to descend, but the gear 1001 in the middle of the horizontal shaft 10 continues to drive the rack column 701 to move upward, driving the screen basin 702 to move upward. The soybean germ on the screen basin 702 moves to the bottom of the fan plate 11 and continues to move the screen basin 702 upward, squeezing the soybean germ and squeezing out the liquid mixture of hexane solvent and oil from the soybean germ. The liquid mixture of hexane solvent and oil flows along the screen hole 703 to the bottom of the barrel 102. The solenoid valve 201 is opened, so that the liquid mixture of hexane solvent and oil is discharged along the oil drain pipe 2.

[0042] After the liquid in the soybean germ is squeezed out, the drive device 3 flips, the horizontal shaft 10 reverses, and the filter mechanism 7 moves downward. The gears 1001 at both ends of the horizontal shaft 10 mesh with the single teeth 5043 above the toothed plate 5041. The upper single tooth 5043 has insufficient travel, so the gears 1001 at both ends begin to mesh with the toothed plate 5041, which will drive the lifting mechanism 5 to move upward. Then, under the influence of gravity, the fan plate 11 begins to move downward. When the sieve basin 702 in the filter mechanism 7 moves downward, the fixed plate 706 at the bottom of the sieve basin 702 contacts the protrusion 105 at the bottom of the cylinder 102. The sieve basin 702 continues to move downward, and the protrusion 105 pushes the fixed plate 706 and the lifting plate 705 connected to the fixed plate 706 upward, pushing out a portion of the squeezed and shaped soybean germ from the sieve basin 702. At this time, the sieve basin 702 has moved one distance upward. Open the door panel 111, and manually or mechanically break the formed soybean embryos apart and take them out from inside the barrel 102. After taking them out, press down on the lifting plate 705 to push the steel ball in the lifting plate 705 into the semi-circular groove 7041 to complete the locking. Finally, close the door panel 111 and carry out the next soybean embryo leaching operation.

[0043] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
