Description

Technical Field

[0001] The present invention relates to the technical field of mechanical pressing and material handling, and specifically to a vegetable oil extraction device. Background Art

[0002] As a key device in the field of oil processing, the vegetable oil extraction device mainly uses the pressing process to apply pressure to oil crops. By applying physical pressure, the cell structure of the oil crops is destroyed, the oil is released, and the internal oil of the oil crops is extracted. When pressing and extracting vegetable oil from oil crops, it is necessary to crush the oil crops to reduce the size of the oil crop particles to increase the surface area per unit volume and promote the effective separation of the oil from the cell wall;

[0003] The crushed oil materials are more easily penetrated by the mechanical force inside the press, so that the pressure energy can be more evenly distributed to each cell, reducing the proportion of intact cells and increasing the contact points for oil release. The crushing operation accelerates the physical destruction process and increases the oil yield of the oil crops;

[0004] When crushing oil crops, the oil crop materials are easily adhered to the outside of the crushing roller, causing the crushing roller to over-crush the materials, so that the released oil is mixed with proteins to form a viscous paste. The viscous substance accumulates on the surface of the crushing roller, causing the two groups of crushing rollers to be affected by asymmetric resistance during rotation, resulting in unbalanced work of the crushing rollers. Technical problems such as bearing wear, jamming, and abnormal noise caused by unbalanced work of the crushing rollers. Therefore, there is an urgent need to develop a vegetable oil extraction device to solve these practical problems. Summary of the Invention

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. 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.

[0039] The first implementation method:

[0040] Refer to Figure 1-12 、 Figure 14-15 A vegetable oil extraction device includes a box body 1. Two groups of electric rods 102 are fixedly connected to one side of the box body 1. The bottom of the box body 1 is communicated with a storage box 101, and a metal perforated plate 7 is inserted and installed at the connection between the storage box 101 and the box body 1. The output end of the electric rod 102 extends into the box body 1 and is fixedly connected to a perforated push plate 103.

[0041] It further includes a crushing box 10 fixedly connected to the top of the box body 1. A crushing component is arranged inside the crushing box 10. The crushing component includes two groups of crushing rollers 302 arranged inside the crushing box 10. A gear disc transmission group 301 is rotatably installed at the center of the front of the crushing box 10, and one end of the gear disc transmission group 301 is fixedly connected to one end of the crushing roller 302. A sealing box 9 is fixedly installed outside the gear disc transmission group 301. An idle motor 3 is fixedly installed at the center of the front of the sealing box 9, and the output end of the idle motor 3 extends into the sealing box 9 and is fixedly connected to the input end of the gear disc transmission group 301.

[0042] It further includes a material anti-adhesion mechanism 4. The material anti-adhesion mechanism 4 includes a servo motor 401 fixedly connected to the top of the crushing box 10, and the output end of the servo motor 401 extends into the crushing box 10 and is fixedly connected to a driving gear disc 410. A driven gear disc 402 is meshed outside the driving gear disc 410. A semi-gear disc 403 is fixedly connected to the bottom of the driven gear disc 402. The semi-gear disc 403 is meshed with a hollow rack plate 404. A brush cleaning frame 405 is fixedly connected to the bottom of the hollow rack plate 404. Two groups of connecting pieces 407 are movably installed at the bottom of the brush cleaning frame 405. One end of the connecting piece 407 is movably installed with a brush plate 408 that cooperates with the brush cleaning frame 405. Both ends of the connecting piece 407 are respectively hinged to the brush cleaning frame 405 and the brush plate 408 through pin shafts, and the brush plate 408 is provided with a limiting groove that slidably cooperates with the inner wall of the crushing box 10.

[0043] A through fixing box 2 is fixedly installed on one side of the bottom of the box body 1. A through lifter 201 is fixedly installed on one side of the fixing box 2, and the top of the lifter 201 is connected to the top of the crushing box 10 through a feed pipe. A pull-out plate 8 is inserted and installed at the bottom of one side of the box body 1, and the pull-out plate 8 is located above the fixing box 2.

[0044] First, the oil material to be extracted is placed inside the crushing box 10. The idling motor 3 drives the gear disc transmission group 301 to rotate. The rotating gear disc transmission group 301 drives the two crushing rollers 302 to rotate relatively to crush the oil crops;

[0045] The servo motor 401 runs to drive the driving gear disc 410 to rotate. The rotating driving gear disc 410 drives the two engaged driven gear discs 402 to rotate relatively. The relatively rotating driven gear discs 402 can drive the two half gear discs 403 at the bottom to rotate synchronously. Through a rotating half gear disc 403, the hollow rack plate 404 can be engaged and driven to move horizontally. When the half teeth of the half gear disc 403 rotate to the disengagement position of the engagement, then through the other rotating half gear disc 403, the hollow rack plate 404 can be engaged and driven to move in the opposite position, so as to achieve reciprocally driving the hollow rack plate 404 to move horizontally;

[0046] The hollow rack plate 404 that moves horizontally reciprocally can drive the brush cleaning frame 405 to move synchronously. The brush cleaning frame 405 that moves horizontally reciprocally reciprocally cleans the oil crop debris adhered to the surface of the crushing roller 302. The moving hollow rack plate 404 also drives the connecting piece 407 to move synchronously;

[0047] The connecting piece 407 that moves can drive the brush plate 408 to move, so that the brush plate 408 moves vertically along the inner wall of the crushing box 10 for cleaning, so that the oil crop material is not easily adhered to the outside of the crushing roller 302 to form a viscous paste, avoiding the accumulation of viscous substances on the surface of the crushing roller 302, causing the two crushing rollers 302 to be affected by asymmetric resistance when rotating, and then resulting in unbalanced work of the crushing roller 302, and solving the technical problems of bearing wear, jamming and abnormal noise caused by unbalanced work of the crushing roller 302;

[0048] Secondly, the crushed oil crop material falls into the box body 1. The two electric rods 102 run to drive the porous push plate 103 to press the oil crops inside the box body 1 to extract oil, so that the vegetable oil inside the oil crops flows through the metal porous plate 7 and is stored inside the storage box 101;

[0049] Finally, by the operator pulling the pull-out plate 8, the oil crops after pressing can enter the fixed box 2. The lifter 201 runs to drive the material to be lifted and conveyed into the crushing box 10 for secondary crushing. The crushed material is conveyed into the box body 1 for secondary pressing. After the compression operation is completed, then by the operator opening the box door on the front of the box body 1, the vegetable oil material after secondary pressing inside the box body 1 can be collected, and the process of extracting vegetable oil is completed.

[0050] The second implementation mode:

[0051] When the material is crushed, the dry friction of the material easily leads to the formation of a protein adhesion layer between the crushing teeth on the outer side of the crushing roller 302, thereby causing the contamination of the next batch of oil crops and the inconvenience of cleaning;

[0052] refer to Figure 1-10 , Figure 10-13 In the second embodiment of the present invention, a gas-liquid switching mechanism 5 is provided on the top of one side of the crushing box 10, and the gas-liquid switching mechanism 5 includes a shell 501, a rotating shaft seat 506 is rotatably installed on the front of the shell 501, and a V-shaped valve plate frame 502 extending to the inside of the shell 501 is fixedly installed on one end of the rotating shaft seat 506, and a through first input pipe 503 is fixedly installed on one side of the top of the shell 501, and a second input pipe 508 is fixedly installed on the other side of the top of the shell 501, and one end of the second input pipe 508 is connected to the top of the shell 501, and a three-way pipe 504 is fixedly connected to one side of the shell 501;

[0053] A telescopic tube is fixedly installed at one end of the three-way pipe 504, and a plurality of first nozzles 406 extending to the inside of the brush cleaning frame 405 are fixedly installed at one end of the telescopic tube. A plurality of second nozzles 409 extending to the inside of the brush plate 408 are fixedly installed at the other end of the telescopic tube, and the first nozzles 406 and the second nozzles 409 are connected through the telescopic tube. A locking piece 507 is fixedly installed on one side of the rotating shaft seat 506 for limiting the V-shaped valve plate frame 502. A locking groove 505 is opened on the front side of the shell 501, and one end of the locking piece 507 extends to the inside of the locking groove 505.

[0054] The second embodiment adopts two working modes. The first working mode is: by rotating the V-shaped valve plate frame 502 to seal one end of the first input pipe 503, the low-pressure steam is cut off from entering the input port of the shell 501, so that the high-pressure gas enters the shell 501, and is transported to the first nozzle 406 and the second nozzle 409 through the three-way pipe 504 to assist the brush cleaning frame 405 and the brush plate 408 with gas cleaning. Specifically:

[0055] After the first input pipe 503 and the second input pipe 508 are connected to the external high-pressure gas and low-pressure steam pipelines respectively, the V-shaped valve plate frame 502 is rotated according to the needs of the user until it contacts one end of the first input pipe 503, thereby achieving the effect of sealing the low-pressure steam input port, and opening the valve of the external gas pipeline to allow the high-pressure gas to enter the shell 501 and be transported to the inside of the three-way pipe 504, and then the high-pressure gas is transported to the first nozzle 406 and the second nozzle 409 through the telescopic pipe;

[0056] Since the first nozzle 406 is located inside the brush cleaning frame 405, it can move along with the reciprocating horizontal position of the brush cleaning frame 405, so that the first nozzle 406 and the brush cleaning frame 405 move synchronously. The oil crop debris adhering to the surface of the crushing roller 302 is reciprocally cleaned by the horizontally moving brush cleaning frame 405, and the cleaned oil crop debris is blown by the first nozzle 406;

[0057] Since the second nozzle 409 is located inside the brush plate 408, it can move along with the vertically moving brush plate 408, so that the second nozzle 409 and the brush plate 408 move synchronously. The inner wall of the crushing box 10 can be cleaned by the moving brush plate 408. Then, the high-pressure air is transported to the inner wall of the crushing box 10 by the second nozzle 409 for auxiliary air cleaning, realizing the function of auxiliary air cleaning for the crushing roller 302 and the inner wall of the crushing box 10;

[0058] By the operator pushing the locking member 507 to move, the moving locking member 507 can drive the rotating shaft seat 506 to rotate. The rotating shaft seat 506 provides a power source for driving the V-shaped valve plate frame 502. By the operator rotating the locking member 507, the rotating position of the rotating shaft seat 506 can be fixed, thereby restricting the moving position of the V-shaped valve plate frame 502.

[0059] The second working mode is different from the first working mode: by rotating the V-shaped valve plate frame 502 to seal one end of the second input pipe 508, the high-pressure gas entering the input port inside the housing 501 is cut off, so that the low-pressure steam enters the housing 501 and is transported to the first nozzle 406 and the second nozzle 409 through the three-way pipe 504 to supplement moisture during the crushing operation of the crushing roller 302. Specifically:

[0060] Rotate the V-shaped valve plate frame 502 to abut against one end of the second input pipe 508 according to the needs of the user, so as to seal the high-pressure air inlet, and open the valve of the external low-pressure steam pipeline to make the low-pressure steam enter the housing 501 and be transported to the three-way pipe 504, and then transport the high-pressure gas to the first nozzle 406 and the second nozzle 409 through the telescopic pipe;

[0061] Since the first nozzle 406 is located inside the brush cleaning frame 405, it can move synchronously with the reciprocating horizontal position of the brush cleaning frame 405. Then, the low-pressure steam is transported to the outside of the crushing roller 302 by the first nozzle 406, so that the brush cleaning frame 405 can supplement moisture to the material while cleaning the material;

[0062] Since the second nozzle 409 is inside the brush plate 408, it can move synchronously with the vertically movable brush plate 408. The second nozzle 409 conveys low-pressure steam to the inner wall of the crushing box 10, thereby supplementing moisture to the oil crop material inside the crushing box 10, making the moisture distribution more uniform, and forming a water film on one side of the surface of the crushing roller 302, thereby reducing the friction coefficient of the crushing roller 302 and preventing the formation of a protein adhesion layer between the crushing teeth on the outer side of the crushing roller 302, solving the problem that a protein adhesion layer is easily formed between the crushing teeth on the outer side of the crushing roller 302, which causes pollution to the next batch of oil crop processing.

[0063] The third implementation method:

[0064] After a long time, the crushing structure is likely to cause the lubricating oil to be exhausted, resulting in problems such as jamming and abnormal noise during crushing, shortening the service life of the crushing structure;

[0065] Reference Figure 14-16 , in the second implementation method of the present invention, a lubricating mechanism 6 is provided on one side of the sealing box 9. The lubricating mechanism 6 includes an oil pump 603. The oil delivery pipe of the oil pump 603 is connected to the top of the sealing box 9 in a penetrating manner. One end of the oil inlet pipe of the oil pump 603 is fixedly installed with an oil tank 601, and one end of the inlet pipe is connected to the bottom side of the oil tank 601 in a penetrating manner. Two filter plates 602 are fixedly installed at the top inside the oil tank 601, and a non-woven fabric layer is fixedly installed between the two filter plates 602.

[0066] The oil pump 603 is energized to operate to generate suction to convey the lubricating oil stored inside the oil tank 601 into the sealing box 9 to lubricate the gear disk transmission group 301 by oil immersion. The lubricating oil is then conveyed into the oil tank 601 through the circulation pipe at the bottom of the sealing box 9, and the filter plates 602 with a porous structure can intercept and filter the tiny debris and impurities doped in the lubricating oil due to the wear of the gear disk transmission group 301. Through the cyclic conveyance by the oil pump 603, the function of automatically maintaining and lubricating the gear disk transmission group 301 is realized, avoiding the problems of jamming and abnormal noise caused by the exhaustion of the lubricating oil after the long-term use of the gear disk transmission group 301.

[0067] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention.
