Abstract
Description
Technical Field
[0001] This utility model relates to the field of rapeseed oil production technology, and in particular to a rapeseed oil raw material screening device. Background Technology
[0002] The raw material for producing rapeseed oil is rapeseed, also known as canola, which is the seed of the cruciferous crop rapeseed. Rapeseed has relatively long pods, produces many pods, and the seeds are plump. Rapeseed contains 37.5% oil.
[0003] -46.3%. The oil content varies slightly depending on the type of rapeseed, and its seeds are one of the main raw materials for oil extraction.
[0004] Existing rapeseed screening devices typically use sieve plates to screen the raw materials. To prevent clogging of the sieve holes during the rapeseed screening process, vibration is used for screening.
[0005] This approach is not only noisy but also costly. Therefore, we propose a rapeseed oil raw material screening device. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapeseed oil raw material screening device.

A collection chamber is located inside the lower side of the screening barrel. A discharge port connected to the collection chamber is located at the bottom of the feeding ramp. A feed inlet and a feed channel are provided on the upper side of the inner wall of the collection chamber. A spiral conveying assembly is installed inside the collection chamber to transport the rapeseed raw material inside the collection chamber to the feed channel. A screening channel is provided inside the screening barrel. A screening platform is fixedly connected to the top of the screening channel. The screening platform is stepped, and its treads are all curved and inclined. An air duct is provided on the kick surface of the screening platform, and a filter plate is fixedly connected to the air duct.

[0025] 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.
[0026] Referring to Figures 1-2, one embodiment of this utility model provides a rapeseed oil raw material screening device, including a screening barrel 1. A feeding ramp 8 is provided at the top of the screening barrel 1, and a barrel cover 2 is fixedly connected to the top of the screening barrel 1. Rapeseed oil raw material is injected through an inlet 3 on one side of the barrel cover 2. Finally, the screened rapeseed oil raw material is discharged outwards through an outlet 5 on the bottom side of the outer wall of the screening barrel 1, where it can be collected. The interior of the screening barrel 1 has a screening channel 16 connected to the outlet 5 for...
[0027] The rapeseed oil raw materials after screening are collected and processed. A screening platform 14 is fixedly connected to the top of the screening channel 16. The screening platform 14 is stepped and its treads are all curved and inclined. With the weight of the rapeseed oil raw materials, the rapeseed oil raw materials roll down on the screening platform 14, reducing vibration costs and noise. During the falling process, the air duct opened at the kick surface of the screening platform 14 is used to absorb the fine and light impurities in the rapeseed oil raw materials. A filter plate 15 is fixedly connected to the air duct. The screening barrel 1 has a collection chamber 13 located under the tread of the screening platform 14. The number of collection chambers 13 is the same as that of the screening platform 14. The collection chambers 13 are connected to the filter plate 15. A collection box 4 is set on the outer wall of the screening barrel 1 at the collection chamber 13. The connection between the collection box 4 and the collection chamber 13 is sealed to collect the fine and light impurities in the rapeseed raw materials.
[0028] Refer to Figure 3- Figure 4A collection chamber 13 is provided on the lower side of the interior of the screening bin 1. A discharge port 9 connected to the collection chamber 13 is provided at the bottom of the feeding ramp 8. A feed port and a feeding channel 6 are provided on the upper side of the inner wall of the collection chamber 13. A conveying bin 12 is located at the center of the interior of the collection chamber 13. The distance between the bottom end of the conveying bin 12 and the bottom inner wall of the collection chamber 13 is 2cm. A machine box 7 is fixed on the top of the conveying bin 12. A motor 10 is fixedly connected inside the machine box 7. Multiple heat dissipation holes are provided on the top of the machine box 7 for heat dissipation of the motor 10. The drive end of the motor 10 is connected to the end of the rotating rod. A rotating rod is rotatably connected inside the conveying bin 12, and a spiral blade 11 is fixedly connected to the outer wall of the rotating rod. Driven by the motor 10, the spiral blade 11 begins to rotate inside the conveying bin 12. The side wall of the conveying bin 12 is connected to the feeding channel 6 so as to use the rotation of the spiral blade 11 to move the collection chamber 13. The rapeseed raw materials inside are transported to 6 feeding channels.
[0029] Working principle: Rapeseed oil raw material containing impurities is injected through inlet 3. Under the action of the feeding ramp 8, the rapeseed oil raw material sequentially enters the collection chamber 13 through outlet 9. Driven by motor 10, the spiral blade 11 begins to rotate inside the conveying barrel 12, thereby forming a flow path within the collection chamber.
[0030] The rapeseed oil raw material inside the 13 is conveyed upward and enters the screening channel 16 from the feed channel 6. At this time, the rapeseed oil raw material rolls downward on the screening platform 14 under the action of gravity. During the fall, the fine and light impurities in the rapeseed oil raw material are absorbed by the suction of the fan and enter the interior of the collection chamber 13. They are then collected through the collection box 4. Finally, the screened rapeseed oil raw material is discharged outward from the discharge port 5. At this point, the collection is complete.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
