Description

Technical Field

[0001] The present application relates to the technical field of vegetable oil production, and more specifically, to a corn germ oil extraction system and an extraction process thereof. Background Art

[0002] The leaching process is to put the corn germ into the leaching tank and dissolve it with a specific solvent (such as hexane). During this process, the oil will be transferred from the solid material to the liquid solvent to form the so-called "wet meal" and oil-containing solution (commonly known as "crude oil"); after the leaching is completed, the obtained solution and water are separated, and finally the solvent is evaporated to obtain corn germ oil.

[0003] When a conventional extraction system extracts crude oil, in order to better transfer the oil to the liquid phase solution, a stirring structure is generally used to fully mix the material with the liquid phase solvent, such as a stirring device in a corn germ oil extraction production system recorded in Publication No. CN221220717U, a stirring rod in a box-type extractor for corn oil separation recorded in Publication No. CN218262400U, and a mixing roller in a box-type extractor for corn oil separation recorded in Publication No. CN214612368U.

[0004] When the crude oil is prepared by the above technical solution, although the material can be fully mixed with the liquid phase solvent by setting the stirring structure, the oil contained in the material is difficult to be fully leached, and in the subsequent separation process, the leached oil-containing solution needs to be transferred from the leaching tank to the filtering equipment for separation treatment, thereby increasing the workload of the leaching process.

[0059] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0060] Reference Figure 1 , Figure 2 and Figure 3 The present application embodiment discloses a corn germ oil extraction system, comprising:

[0061] The tank body 100 is used to provide a working space for extracting corn germ oil, and the tank body 100 contains a solvent for extracting oil;

[0062] The bag filter element 200 is arranged in the tank body 100 through a disassembly structure 300, and the material to be processed is placed through the discharge port 210 of the bag filter element 200; wherein the disassembly structure 300 includes two first extrusion members 310 arranged opposite to each other; the two first extrusion members 310 can clamp the discharge port 210 of the bag filter element 200, and when the two first extrusion members 310 clamp the bag filter element 200, the two first extrusion members 310 form the first shape 320 toward one side of the second extrusion member 400;

[0063] The second extrusion piece 400 is arranged in the tank body 100, and the second extrusion piece 400 is driven to reciprocate along the tank body 100. One side of the second extrusion piece 400 has a second shape 410, and the second shape 410 is adapted to the first shape 320; and in the working state, the bag filter 200 is located between the first extrusion piece 310 and the second extrusion piece 400, so that when the second extrusion piece 400 reciprocates toward the first extrusion piece 310, the material in the bag filter 200 can be repeatedly squeezed fully under the cooperation of the first shape 320 and the second shape 410, so that the oil contained in the material is fully immersed in the solvent, and the corn germ oil is fully leached out.

[0064] A top plate 130 is disposed at the top of the tank body 100 , and an opening 131 is provided on the top plate 130 . The opening 131 is provided to facilitate the placement of the bag filter element 200 after the material is contained.

[0065] Furthermore, in the above technical solution, after the leaching process is completed, the leached crude oil is directly discharged from the tank body 100 for the next step of processing, while the solid residue is always retained in the bag filter element 200. By moving at least one first extrusion member 310, the bag filter element 200 can be released from between the two first extrusion members 310, which is convenient for removing the solid residue. There is no need for a separate solid-liquid separation process, thereby reducing the workload of the entire leaching process.

[0066] It can be understood that in the above technical solution, the vertical reciprocating movement of the second extrusion member 400 along the tank body 100 is controlled by the first linear mechanism 420, and the first linear mechanism 420 is a mechanism with a linear output, such as a pneumatic mechanism, a hydraulic mechanism or a linear guide rail; in a specific solution of the present application, the first linear mechanism 420 is a hydraulic rod.

[0067] In addition, if Figure 3-6 As shown, in the above technical solution, at least one of the two first extrusion members 310 in the disassembly mechanism is driven by a second linear mechanism 330. Similar to the first linear mechanism 420, the second linear mechanism 330 is also a mechanism with a linear output, such as a pneumatic mechanism, a hydraulic mechanism or a linear guide rail; in a specific solution of the present application, the second linear mechanism 330 is also a hydraulic component; in the technical solution of the present application, the second linear mechanism 330 is installed above the top plate 130, and the output end of the second linear mechanism 330 is arranged toward the opening 131.

[0068] Specifically, a first extrusion piece 310 is fixed to one output end of the first linear mechanism 420 , and the first extrusion piece 310 can move in the horizontal / vertical direction when driven by the first linear mechanism 420 ; the relative movement of the two first extrusion pieces 310 can clamp or release the bag filter 200 .

[0069] In some technical solutions, one side of the first extrusion member 310 directly forms the first shape 320, and the first shape 320 is adapted to the second shape 410, and can fully extrude the bag filter 200 located between the first extrusion member 310 and the second extrusion member 400; in other technical solutions, the first extrusion member 310 is a plate member, one side of which is detachably connected to a top block 340, and the first shape 320 is formed by two top blocks 340; this technical solution makes it convenient to replace the top block 340 to form different first shapes 320.

[0070] In addition, the first shape 320 may be Figure 6 The projection shown is in the shape of a broken line, and can also be in the shape of a wavy line; the second shape 410 is a broken line / wavy line-like shape adapted thereto to facilitate squeezing of the material in the bag filter element 200.

[0071] In a more preferred technical solution, the corn germ oil extraction system further includes a filter plate assembly 500 slidably disposed in the tank body 100;

[0072] Specifically, if Figure 7 and Figure 8 As shown, the filter plate assembly 500 includes a first filter plate 510 and a second filter plate 520; wherein the first filter plate 510 is driven to rise and fall vertically in the tank body 100, and a first filter hole 511 is provided through the first filter plate 510; the second filter plate 520 is rotatably provided on one side of the first filter plate 510, and a second filter hole 521 is provided on the second filter plate 520 corresponding to the first filter hole 511;

[0073] Among them, the second filter plate 520 can rotate relative to the first filter plate 510 so that the first filter hole 511 and the second filter hole 521 form a liquid channel for the passage of solvent; in the working state, when the second extrusion member 400 is close to the first extrusion member 310, the second filter hole 521 and the first filter hole 511 are relatively misaligned so that the liquid channel is closed.

[0074] As can be seen from the above explanation, in the technical solution of the present application, the solid residue is always kept in the bag filter element 200 by setting the bag filter bag, and there is no need to separate the solid and the liquid. Therefore, the second filter plate 520 and the first filter plate 510 that rotate relatively in the filter plate assembly 500 in the above technical solution of the present application have two functions:

[0075] First, during the rising process of the filter plate assembly 500, when the second extrusion member 400 approaches the first extrusion member 310, the liquid channel is closed, and the filter plate assembly 500 can drive part of the liquid to move upward, so that when the second extrusion member 400 cooperates with the first extrusion member 310 to squeeze the bag filter element 200, the liquid can infiltrate around the bag filter bag, so that the oil squeezed out of the bag filter bag can quickly immerse into the solution;

[0076] Secondly, in other states, when the filter plate assembly 500 rises or falls, the second filter plate 520 rotates relative to the first filter plate 510, so that the size of the liquid channel changes, and the liquid in the tank body 100 passes through the liquid channel, so that the liquid in the tank body 100 can flow quickly, so that the solvent and the oil are fully mixed.

[0077] In the above technical solution, the second extrusion member 400 is arranged at the top of the first filter plate 510, and the second filter plate 520 is embedded in the first filter plate 510. The rotation of the second filter plate 520 relative to the first filter plate 510 can be achieved by an external driving device. For example, the second filter plate 520 is transmitted and arranged at the output end of a driving motor. By setting a suitable transmission mechanism, the driving motor can drive the second filter plate 520.

[0078] In another technical solution of the present application, the corn germ oil extraction system also includes a driving member 530 connected to one side of the second filter plate 520; a first driving groove 110 is opened on the inner side of the tank body 100 corresponding to the driving member 530, and the driving member 530 can be embedded in the first driving groove 110 in the working state; so that when the first filter plate 510 drives the second filter plate 520 to move along the tank body 100, the second filter plate 520 can rotate relative to the first filter plate 510.

[0079] That is, in this technical solution, there is no need for an additional driving motor and transmission mechanism. By using the first driving groove 110 opened on the inner side of the tank body 100 and the driving member 530 arranged on one side of the second filter plate 520, the second filter plate 520 can be rotated relative to the first filter plate 510 during the rising or falling process of the filter plate assembly 500, so that the filter plate assembly 500 can drive the liquid to flow rapidly.

[0080] In the above technical solution, when the driving member 530 is located at the bottom or top of the first driving groove 110, the liquid channel is closed; so that when the filter plate assembly 500 moves within the height range of the first driving groove 110, under the action of the first driving groove 110, the second filter plate 520 rotates relative to the first filter plate 510 to achieve rapid flow of liquid in the tank body 100.

[0081] It should be noted that, in the above technical scheme, the rotation mode of the second filter plate 520 relative to the first filter plate 510 depends on the shape of the first driving groove 110. The technical scheme of the embodiment of the present application does not limit the rotation mode of the second filter plate 520 relative to the first filter plate 510, that is, in the above technical scheme, the shape of the first driving groove 110 is not limited. For example, the first driving groove 110 can be a spiral shape arranged on the inner wall of the tank body 100, or it can be a wave shape or a C shape. The present application defines that when the top and bottom of the first driving groove 110 are at the top and bottom ends, the second filter plate 520 rotates relative to the first filter plate 510 until the liquid channel is closed; in a preferred scheme, the top and bottom ends of the first driving groove 110 are located on the same vertical line of the inner wall of the tank body 100, and the second driving groove 120 is provided on the vertical line;

[0082] The top of the first driving groove 110 is arranged close to the top of the second driving groove 120, and the top of the first driving groove 110 is connected to the second driving groove 120 and has a smooth transition; the bottom of the first driving groove 110 is arranged close to the bottom of the second driving groove 120, and the bottom of the first driving groove 110 is connected to the second driving groove 120 and has a smooth transition;

[0083] The top and bottom ends of the second driving groove 120 both pass through the corresponding connecting points between the second driving groove 120 and the first driving groove 110 ; and a liquid outlet is provided at the bottom end of the tank body 100 .

[0084] In this technical solution, when the driving member 530 moves to the top of the first driving groove 110, the liquid channel is closed, and the filter plate assembly 500 forms a partition, which can drive part of the liquid to continue to rise until the bag filter 200 is released, until the second extrusion member 400 cooperates with the first extrusion member 310 to extrude the bag filter 200, and the oil in the bag filter 200 can quickly enter the solvent of the surrounding liquid, which is convenient for the full leaching of corn germ oil;

[0085] When the leaching is completed and the material needs to be discharged, the liquid material is discharged from the liquid outlet arranged at the bottom of the tank body 100. When the driving member 530 moves to the top of the first driving groove 110, the filter plate assembly 500 can form a partition, and then the driving member 530 moves along the second driving groove 120. During this process, the liquid channel is always in a closed state, and the downward movement of the filter plate assembly 500 helps to push the liquid in the tank body 100 to quickly discharge from the tank body 100.

[0086] In a specific technical solution, the driving member 530 is a protruding magnet; correspondingly, the tank body 100 is made of non-magnetic materials such as stainless steel, and a first electromagnetic member is configured on one side of the top end of the first driving groove 110; and a second electromagnetic member is configured on one side of the bottom end of the second driving groove 120.

[0087] In this technical solution, when the driving member 530 moves to the top along the first driving groove 110, due to the smooth transition between the top of the first driving groove 110 and the second driving groove 120, the driving member 530 can directly transition to the second driving groove 120 under the drive of the first linear mechanism 420, and the liquid channel is in a closed state at this time; when continuing to move upward along the second driving groove 120, the second driving groove 120 arranged vertically makes the second filter plate 520 no longer continue to rotate relative to the first filter plate 510, that is, at this time, the filter plate assembly 500 forms a partition to drive the liquid to move upward;

[0088] When the second extrusion member 400 squeezes the bag filter element 200 and descends along the second driving groove 120, when it moves to the connection between the second driving groove 120 and the first driving groove 110, if the leaching work is not completed at this time, the first electromagnetic member is energized, so that the driving member 530 is adsorbed and enters the first driving groove 110. Driven by the first driving groove 110, the second filter plate 520 rotates relative to the first filter plate 510, so that the liquid channel is sometimes larger and sometimes smaller, which is conducive to the full flow of the liquid;

[0089] If the leaching work has been completed, the second extrusion member 400 can squeeze the bag filter element 200 to squeeze out the liquid contained in the material for solid-liquid separation; when the filter plate assembly 500 continues to move downward to the connection between the second driving groove 120 and the first driving groove 110, the liquid channel remains closed. At this time, the first electromagnetic member does not need to be energized, so that the driving member 530 continues to move along the second driving groove 120, that is, the filter plate assembly 500 pushes out the liquid in the tank body 100, which is conducive to the rapid discharge of the liquid;

[0090] When the filter plate assembly 500 acts as a partition to push the liquid out of the tank body 100 and needs to participate in the next leaching process, the filter plate assembly 500 moves upward under the action of the first linear mechanism 420. When the driving member 530 moves to the connection between the second driving groove 120 and the first driving groove 110, the second electromagnetic member is energized and magnetically conductive, and the driving member 530 enters the first driving groove 110 under the adsorption of the second electromagnetic member.

[0091] That is, during normal leaching operation, the driving member 530 only moves along the top portion of the first driving groove 110 and the second driving groove 120 (eg Fig. 9 a) shown in the path), during which only the first electromagnetic member works; during the drainage process when the leaching work is completed, the driving member 530 only moves along the second driving groove 120 (such as Fig. 9 b) shown in the path); when the drainage is completed and enters the next leaching process, the driving member 530 enters the first driving groove 110 along the bottom end of the second driving groove 120 (such as Fig. 9 c) of the path shown), the second electromagnetic member only works in this process.

[0092] In other technical solutions, such as Fig.10 and Fig.11 As shown, a top cover 600 is detachably provided at the top of the tank body 100 , and an escape channel 610 for accommodating the bag filter 200 is penetrated through the top cover 600 ; wherein, a cover plate 700 is arranged at the top of the escape channel 610 , and the cover plate 700 is used to cover the escape channel 610 .

[0093] In a specific embodiment of the present application, the top cover 600 is driven by the third linear mechanism 620 , and the third linear mechanism 620 drives the top cover 600 to move away from / engage with the tank body 100 .

[0094] Similar to the first linear mechanism 420 and the second linear mechanism 330 , the third linear mechanism 620 uses a hydraulic rod.

[0095] At least one guide wheel 710 is connected to one side of the cover plate 700; a support frame 800 is also connected to one side of the tank body 100, and a guide plate 810 is arranged at the top of the support frame 800. One side of the guide plate 810 is arranged in a circular arc transition, and the guide wheel 710 can abut against the circular arc transition.

[0096] When the top cover 600 rises, the guide wheel 710 cooperates with the guide plate 810 to rotate and open the cover plate 700. When the top cover 600 descends, the guide wheel 710 cooperates with the guide plate 810 to rotate and close the cover plate 700.

[0097] In summary, when the corn germ oil extraction system disclosed in the embodiment of the present application is in use, when the equipment is used, the top cover 600 is driven to rise by the third linear mechanism 620; then the second linear mechanism 330 drives the first extrusion member 310 to move the two first extrusion members 310 relatively away from each other, and the discharge port 210 of the bag filter 200 filled with material is placed between the two first extrusion members 310, and then the second linear mechanism 330 drives the two first extrusion members 310 to move relative to each other, clamping the bag filter 200, and installing the bag filter 200 filled with corn germ granular material at the bottom of the top cover 600, putting a specific solution in the tank body 100, and then the top cover 600 is driven to descend by the third linear mechanism 620 to extract the corn germ oil.

[0098] During the leaching process, the filter plate assembly 500 and the second extrusion member 400 are driven to rise and fall by the first linear mechanism 420, and the second extrusion member 400 cooperates with the first extrusion member 310 to extrude the material inside the bag filter element 200, so that the corn germ granules are in better contact with the specific solution; during this process, the second filter plate 520 rotates relative to the first filter plate 510 to change the liquid channel, which facilitates the flow of the liquid in the tank body 100;

[0099] After the leaching is completed, the liquid contained in the material in the bag filter element 200 is squeezed out by the cooperation of the second extrusion piece 400 and the first extrusion piece 310 , and then the filter plate assembly 500 moves downward to push the liquid out of the tank body 100 .
