[0002] The screw oil press is an advanced continuous oil pressing equipment that is widely used in the oil pressing process of various oil crops.

[0003] Currently, document CN214188589U discloses a screw oil press for flaxseed oil processing, relating to the field of oil presses. It includes a housing with a screen inside, and multiple sets of screws inside the housing. The outer walls of all the screws are threaded, and rotating shafts penetrating the screen and housing are located on both sides of each screw. This allows the flaxseed to be fully crushed, ensuring complete oil extraction. Simultaneously, it reduces wear between the screws, increasing the equipment's lifespan.

[0004] In practical use, the above-mentioned existing technology feeds the oil press through the feed hopper, which can easily cause the raw materials to clump together and block the feed hopper. The raw materials are manually pushed to process them, which affects efficiency. After the raw materials are pressed to extract oil, the residue and oil are separated by a screen and activated carbon adsorption screen. However, because the oil has low fluidity and a certain surface tension, the flow rate during filtration is slow, resulting in low filtration efficiency. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] like Figure 1-4As shown, this utility model provides a screw oil press, including a base 1, a pressing barrel 2 installed on the base 1, an oil pressing shaft 3 for pressing oil rotatably installed inside the pressing barrel 2, a feeding box 4 connected to the upper left end of the pressing barrel 2, a screw conveyor shaft 5 for conveying raw materials rotatably installed inside the feeding box 4, an oil discharge pipe 6 connected to the lower right end of the pressing barrel 2, a filter barrel 7 fixedly installed at the bottom of the oil discharge pipe 6, a centrifugal filter cylinder 8 installed inside the filter barrel 7, and a motor 9 installed on the front side of the pressing barrel 2, the motor 9 synchronously driving the oil pressing shaft 3, the screw conveyor shaft 5 and the centrifugal filter cylinder 8 to rotate.

[0027] In this embodiment, both ends of the screw conveyor shaft 5 extend to the outside of the feed box 4, and the left end of the oil pressing shaft 3 extends to the outside of the pressing barrel 2. A pulley I 10 is fixedly sleeved on the output shaft of the motor 9, a pulley II 11 is fixedly sleeved on the outer wall of the oil pressing shaft 3, and a pulley III 12 is fixedly sleeved on the left end of the screw conveyor shaft 5. A belt I 13 is provided for transmission between pulley I 10 and pulley II 11, and a belt II 14 is provided for transmission between pulley II 11 and pulley III 12. The motor 9 drives pulley I 10 to rotate, and pulley I 10 drives pulley II 11 to rotate through the transmission of belt I 13, thereby driving the oil pressing shaft 3 to perform pressing. Pulley II 11 also drives pulley III 12 to rotate through belt II 14, and pulley III 12 drives the screw conveyor shaft 5 to transport the raw materials.

[0028] In this embodiment, two interlocking dispersing rollers 15 are rotatably arranged inside the opening on the upper right side of the feed box 4. The right ends of both dispersing rollers 15 extend to the right side of the feed box 4. The right ends of the two dispersing rollers 15 are respectively fixedly sleeved with meshing gears 16. The right end of the screw conveyor shaft 5 is fixedly sleeved with a pulley IV 17. The right end of one of the dispersing rollers 15 is fixedly sleeved with a pulley V 18. A belt III 19 is provided between pulley IV 17 and pulley V 18 for transmission. When pulley III 12 drives the screw conveyor shaft 5 to convey raw materials, the screw conveyor shaft 5 synchronously drives pulley IV 17 to rotate. Pulley IV 17 drives pulley V 18 to rotate through belt III 19. This dispersing roller 15 drives the other dispersing roller 15 to rotate through two meshing gears 16. The two dispersing rollers 15 rotate relative to each other to disperse and initially crush the raw materials, breaking up the clumps of raw materials and making the conveying more convenient.

[0029] In this embodiment, a rotating shaft 20 is rotatably mounted on the bottom of the filter barrel 7 via a sealed bearing. The top end of the rotating shaft 20 is located inside the filter barrel 7 and is fixedly connected to the bottom of the centrifugal filter cartridge 8. A horizontal shaft 21 is rotatably mounted on the base 1. A worm sleeve 22 is fixedly sleeved on the right end of the horizontal shaft 21. A worm wheel 23 that meshes with the worm sleeve 22 is fixedly sleeved on the bottom end of the rotating shaft 20. Rotation of the horizontal shaft 21 can drive the worm sleeve 22 to rotate the worm wheel 23 that meshes with it. The worm wheel 23 drives the rotating shaft 20 to rotate the centrifugal filter cartridge 8 for filtration.

[0030] In this embodiment, a pulley VI 24 is fixedly sleeved on the left end of the horizontal shaft 21. A belt IV 25 is provided between the pulley VI 24 and the pulley II 11 for transmission. When the pulley II 11 rotates, it drives the pulley VI 24 to rotate through the belt IV 25, thereby realizing the rotation of the horizontal shaft 21.

[0031] In this embodiment, the filter barrel 7 includes a stepped section 71 fixedly connected to the bottom of the oil drain pipe 6. A square barrel 72 connected to the stepped section 71 is fixedly arranged below it. An oil outlet 73 is opened on the side of the square barrel 72. An oil hopper 74 located below the oil outlet 73 is fixedly connected to the side of the square barrel 72. The opening size of the top of the centrifugal filter cylinder 8 is larger than the connection between the stepped section 71 and the square barrel 72, and the top of the centrifugal filter cylinder 8 completely covers the connection between the stepped section 71 and the square barrel 72. The pressed oil flows into the square barrel 72 through the stepped section 71, ensuring that the oil can completely enter the centrifugal filter cylinder 8.

[0032] In this embodiment, the oil outlet 74 is inclined downward from left to right, and the inner bottom wall of the square barrel 72 is inclined with the same inclination angle as the oil outlet 74, which facilitates the discharge of oil.

[0033] How to use and how to work this device:

[0034] When using this device, the motor 9 is first turned on. The motor 9 drives pulley I 10, which in turn drives pulley II 11 through belt I 13. Pulley II 11 drives the oil pressing shaft 3 to rotate, and at the same time, belts II 14 and IV 25 drive pulleys III 12 and VI 24 to rotate. Pulley III 12 drives the screw conveyor shaft 5 to rotate. When the screw conveyor shaft 5 rotates, it drives pulley IV 17 to rotate, which in turn drives pulley V 18 through belt III 19 to rotate one of the dispersing rollers 15. This dispersing roller 15 drives the other dispersing roller 15 to rotate through two meshing gears 16. Pulley VI 24 drives the horizontal shaft 21 to rotate. The rotation of the horizontal shaft 21 drives the worm sleeve 22 to rotate the worm wheel 23 that meshes with it. The worm wheel 23 drives the rotating shaft 20 to rotate the centrifugal filter cartridge 8. Therefore, the rotation of the oil pressing shaft 3, the screw conveyor shaft 5, the dispersing roller 15, the horizontal shaft 21 and the centrifugal filter cartridge 8 can be realized simultaneously through the motor 9. This multi-purpose machine reduces the overall cost of the equipment.

[0035] Raw materials are fed into the feed box 4 through the top opening. Two dispersing rollers 15 rotate relative to each other to break up the clumps of raw materials and convey them downwards. After the raw materials are broken up, they are conveyed more conveniently. Then, the broken raw materials are conveyed to the left by the rotating screw conveyor shaft 5 and fall into the pressing barrel 2 for pressing by the oil pressing shaft 3. The dispersing rollers 15 and the screw conveyor shaft 5 assist in feeding, making it less likely to cause blockage during feeding and improving the efficiency of the screw oil press.

[0036] After the raw material is pressed into oil, it enters the filter tank 7 through the oil discharge pipe 6 and drips into the centrifugal filter cartridge 8. The pulley VI 24 causes the horizontal shaft 21 to rotate. The rotation of the horizontal shaft 21 drives the worm sleeve 22 to rotate the worm wheel 23 that meshes with it. The worm wheel 23 drives the rotating shaft 20 to rotate the centrifugal filter cartridge 8. The centrifugal force generated by the rotation of the centrifugal filter cartridge 8 can accelerate the rate at which the oil passes through the centrifugal filter cartridge 8, thereby greatly improving the rate of oil separation and thus improving the filtration efficiency.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
