Description

Technical Field

[0001] This utility model relates to the technical field of vegetable oil processing, specifically to a raw material screening device for vegetable oil processing. Background Technology

[0002] Rapeseed oil is a common vegetable oil in daily life, which is extracted from rapeseed. Vegetable oils mainly contain vitamin E, vitamin K, calcium and other minerals and fatty acids. People need to ensure the oil content in their daily food. In the processing and production of vegetable oil, the raw materials need to be screened to reduce the content of impurities and ensure the quality of vegetable oil.

[0003] Utility model patent CN218963254U discloses a raw material screening device for vegetable oil processing, belonging to the technical field of vegetable oil processing. It addresses the problem in existing technologies where materials, during harvesting, storage, and transportation, are mixed with impurities such as leaves, rapeseed hulls, and dust. In practical operation, these impurities are difficult to filter and separate through a screen, affecting the quality of the vegetable oil. The device includes a screening frame with a feed hopper fixed on it; a screening assembly comprising a fixed frame fixed to the screening frame, a movably mounted screen plate within the fixed frame, a movable cylinder fixed through the center of the screen plate, and a drive rod rotatably connected to the screening frame to drive the movable cylinder to shake; and a dispersion assembly including a rotating shaft rotatably connected to the screening frame. In this utility model, a motor drives a drive rod to rotate, which causes a cam to push the movable cylinder and screen plate to sway circumferentially within a fixed frame, thereby achieving material screening and conveying. The drive rod drives the rotating shaft to rotate synchronously, which in turn drives the dispersing rod and fan blades to rotate, fully breaking up and separating agglomerated materials, and blowing away light impurities such as blades, rapeseed hulls, and dust from the materials. The device has a compact overall structure and better linkage and coordination effect.

[0004] However, the above patent still has shortcomings: although the patent can screen rapeseed, because the volume of some rapeseed is almost the same as the holes inside the screen plate, some rapeseed will get stuck inside the holes inside the screen plate, which will cause the screen plate to be blocked and affect the screening of rapeseed.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 The present invention will describe the above technical solution in detail through the following embodiments:

[0026] A raw material screening device for vegetable oil processing includes: a screening box 1; a storage box 2 is provided on one side of the top of the screening box 1, and a feeding port 3 is provided at the center of the bottom of the storage box 2; a screening cylinder 4 is rotatably connected inside the screening box 1, and the screening cylinder 4 cooperates with the feeding port 3; a partition 5 is provided in the middle of the screening cylinder 4, and the partition 5 is fixedly connected to the screening box 1; a control box 6 with an internal touch screen is fixedly connected to one side of the screening box 1; an anti-clogging screening mechanism 7 is provided inside the screening cylinder 4; a power mechanism 8 for quantitatively conveying materials is provided inside the storage box 2. The user pours rapeseed into the storage box 2, and the rapeseed inside the storage box 2 is quantitatively conveyed into the screening cylinder 4 through the cooperation of the power mechanism 8 and the feeding port 3. The screening cylinder 4 rotates slowly inside the screening box 1 through the cooperation of the screening mechanism 7, thereby driving the rapeseed to continuously tumble and be conveyed inside the screening cylinder 4, and screening the rapeseed according to its volume while it is tumbling and being conveyed.

[0027] like Figures 2 to 4As shown, the screening mechanism 7 includes: a screening cylinder 4 with a plurality of primary screening holes 9 evenly distributed inside the end near the feed inlet 3; a screening cylinder 4 with a plurality of secondary screening holes 10 evenly distributed inside the end away from the feed inlet 3, the diameter of the secondary screening holes 10 being larger than that of the primary screening holes 9; a conveying screw belt 11 fixedly connected to the inner wall of the screening cylinder 4; a first gear 12 fixedly connected to the outer surface of the end of the screening cylinder 4 away from the feed inlet 3, a second gear 13 meshing with the top of the first gear 12; a first rotating shaft 14 fixedly connected to the center of the second gear 13; and the end of the first rotating shaft 14 away from the second gear 13 fixedly connected to the output end of a first motor 15. The machine 15 is fixedly connected to the screening box 1. When the first motor 15 is started, the output end of the first motor 15 drives the first rotating shaft 14. While the first rotating shaft 14 rotates, it drives the second gear 13. While the second gear 13 rotates, it drives the first gear 12 to rotate slowly and uniformly. While the first gear 12 rotates, it drives the screening cylinder 4 to rotate slowly and uniformly inside the screening box 1. While the screening cylinder 4 rotates, it drives the conveyor belt 11. The conveyor belt 11 continuously pushes the rapeseed to move and convey, thereby causing the rapeseed to continuously tumble and convey. While the rapeseed is tumbling and conveying, it falls to the bottom of the screening box 1 through the primary screening hole 9 and the secondary screening hole 10.

[0028] like Figure 3 and Figure 4 As shown, the first gear 12 is meshed with the third gear 16 on both sides. The center of the third gear 16 is fixedly connected to the second rotating shaft 17, which is rotatably connected to the screening box 1. The outer surface of the second rotating shaft 17 located inside the screening box 1 is fixedly connected to the brush roller 18. The brush roller 18 cooperates with the screening cylinder 4. When the first gear 12 rotates, it drives the third gear 16 on both sides to rotate at high speed. When the third gear 16 rotates, it drives the second rotating shaft 17. The second rotating shaft 17 drives the brush roller 18 to rotate at high speed. When the brush roller 18 rotates, the bristles on its surface continuously squeeze and push the rapeseed stuck in the first screening hole 9 and the second screening hole 10, so that the rapeseed separates and falls out from the first screening hole 9 and the second screening hole 10.

[0029] like Figure 5As shown, the power mechanism 8 includes: a crossbeam 19 fixedly connected to the top center of the storage box 2; a second motor 20 fixedly connected to the top center of the crossbeam 19; a third rotating shaft 21 fixedly connected to the output end of the second motor 20; the end of the third rotating shaft 21 away from the second motor 20 passes through the crossbeam 19 and extends into the interior of the feed inlet 3; an auger blade 22 is fixedly connected to the outer surface of the third rotating shaft 21 located inside the feed inlet 3; the auger blade 22 is adapted to the feed inlet 3; when the second motor 20 is started, the output end of the second motor 20 drives the third rotating shaft 21; while the third rotating shaft 21 rotates, it drives the auger blade 22; while the auger blade 22 rotates, it quantitatively conveys rapeseed from the interior of the feed inlet 3 to the interior of the screening cylinder 4 through the cooperation of the feed inlet 3, thereby achieving the purpose of quantitative conveying of rapeseed.

[0030] like Figure 2 As shown, screening ports 23 are provided on both sides of the bottom of the screening box 1. An inclined conveying hopper 24 is fixedly connected to the bottom of each screening port 23. The two screening ports 23 are respectively matched with the primary screening hole 9 and the secondary screening hole 10. After the rapeseed falls into the screening box 1 from the primary screening hole 9 and the secondary screening hole 10, it falls into the conveying hopper 24 through the screening port 23. Finally, it slides to the outside of the device through the inclined surface of the conveying hopper 24. Impurities larger than the primary screening hole 9 and the secondary screening hole 10 are discharged to the outside of the device through the end of the screening cylinder 4 away from the storage box 2.

[0031] like Figure 1 As shown, two structural plates 25 are provided on the side of the storage box 2 near the screening box 1. Both structural plates 25 are fixedly connected to the storage box 2 and the screening box 1, which improves the stability of the connection between the storage box 2 and the screening box 1, thereby improving the structural strength of the device.

[0032] like Figure 1 As shown, support rods 26 are provided at the four corners of the bottom of the screening box 1. The top of the support rods 26 are fixedly connected to the screening box 1, and the bottom of the support rods 26 are fixedly connected to the base plate 27. The four corners of the bottom of the base plate 27 are fixedly connected to casters 28 with braking function, which makes it convenient for users to push the device to move.

[0033] Working principle: The user pours rapeseed into the storage bin 2, then starts the first motor 15 and the second motor 20. The output of the second motor 20 drives the third rotating shaft 21. Simultaneously, the rotation of the third rotating shaft 21 drives the auger blades 22. The auger blades 22, in conjunction with the feeding port 3, quantitatively convey the rapeseed from inside the feeding port 3 into the screening cylinder 4, thus achieving the purpose of quantitative conveying of rapeseed. This function of quantitatively discharging rapeseed avoids the accumulation of large amounts of rapeseed inside the device, which would affect the efficiency of rapeseed screening and improves practicality. The output of the first motor 15 drives the first rotating shaft 14. Simultaneously, the rotation of the first rotating shaft 14 drives the second gear 13. The rotation of the second gear 13, in turn, drives the first gear 12 to rotate slowly and uniformly. Simultaneously, the rotation of the first gear 12 drives the screening cylinder 4 to rotate slowly and uniformly inside the screening box 1. The rotation of the screening cylinder 4 also drives the conveyor belt 11, which continuously pushes the rapeseed seeds for movement and transport, causing the rapeseed seeds to tumble and be transported. While tumbling and being transported, the rapeseed seeds pass through the primary screening hole 9 and the secondary screening hole 10. After falling into the screening box 1 through hole 10, the material falls through the screening port 23 into the conveying hopper 24, and finally slides to the outside of the device through the inclined surface of the conveying hopper 24. Impurities larger than the primary screening hole 9 and the secondary screening hole 10 are discharged to the outside of the device through the end of the screening cylinder 4 away from the storage box 2. At the same time, the first gear 12 drives the third gears 16 on both sides to rotate at high speed. The rotation of the third gears 16 drives the second rotating shaft 17, which drives the brush roller 18 to rotate at high speed. As the brush roller 18 rotates, the bristles on its surface are constantly squeezed and pushed to get stuck in the primary screening hole. The rapeseed in the primary screening hole 9 and the secondary screening hole 10 is separated and detached from the inside of the primary screening hole 9 and the secondary screening hole 10. This continuously pushes out the rapeseed stuck inside the screening cylinder 4 from the holes inside the screening cylinder 4, thereby preventing the rapeseed from clogging the screening cylinder 4 and affecting the rapeseed screening. This solves the problem that although the existing raw material screening device for vegetable oil processing can screen rapeseed, some rapeseed is almost the same size as the holes inside the screen plate, causing some rapeseed to get stuck inside the holes inside the screen plate, thus clogging the screen plate and affecting the screening of rapeseed.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. 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 therein. 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.
