[0002] Rapeseed oil is a common vegetable oil obtained by pressing rapeseed. Rapeseed oil is rich in various nutrients, such as unsaturated fatty acids and vitamin E, and has health benefits such as lowering blood lipids and preventing cardiovascular diseases, so it is deeply favored by consumers.

[0003] In the prior art, an authorized patent with announcement number CN220177466U discloses a screening device for rapeseed oil production and processing, including a feed hopper, the bottom end of the feed hopper is connected to a discharge port, and a U-shaped connecting plate is fixedly installed on the outer surface of the discharge port, and a coarse filter screen and a medium filter screen are respectively installed in two groups of the fixed grooves, and a square through groove is opened on the outer surface of one end of the feed hopper. The utility model uses the coarse filter screen to filter out larger impurities to avoid clogging the fine filter screen, and at the same time can reduce the workload of the fine filter screen and extend its service life. The medium filter screen can filter out some larger impurities and particles without excessively limiting the screening efficiency of the fine filter screen, further improving the screening efficiency and stability of the vibrating screen, reducing maintenance costs and the occurrence of equipment failures, and using the fine filter screen to screen fine particle materials, thereby increasing people's work efficiency.

[0004] However, the above technical solution still has the following shortcomings when it is actually used: the three filter screens in the above device are all inclined, so that during the screening process, the rapeseed oil material will accumulate at the inclined bottom of the filter screen, seriously affecting the screening efficiency. In this regard, we propose a rapeseed oil processing and screening equipment to solve the above problems. Utility Model Content

A guide rod 8 is fixedly welded on the top and bottom ends of the lifting rod 6. Two guide seats 9 are fixedly welded on the front side wall of the screening drum 1, and the two guide rods 8 are respectively slidably connected to the two guide seats 9.

[0022] The driving assembly includes an L-shaped mounting frame 10, which is fixedly welded on the front side wall of the screening drum 1, and a driving motor 11 is fixedly installed on the L-shaped mounting frame 10. A turntable 12 is fixedly installed on the output shaft of the driving motor 11, and a rotating column 13 is fixedly welded on the turntable 12. The rotating column 13 is eccentrically arranged on the turntable 12, and a rocker 14 is rotatably connected to the rotating column 13. The top of the rocker 14 is rotatably connected to a push-pull rod 15, and the end of the push-pull rod 15 away from the rocker 14 is fixedly welded to the side wall of the lifting rod 6. After the driving motor 11 is started, the turntable 12 can be driven to rotate. When the turntable 12 rotates, the rotating column 13 can be driven to rotate around the center of the turntable 12, so that the rocker 14 flips back and forth, and drives the push-pull rod 15 to move back and forth up and down, so that the lifting rod 6 can be lifted and lowered reciprocatingly.

[0023] A vibration motor is installed on the rear side wall of the screening drum 1. The vibration motor is a prior art and is not shown in the figure. After being started, the vibration motor can make the screening drum 1 vibrate to improve the screening effect.

[0024] A base 16 is provided at the bottom of the screening drum 1, and four support columns 17 are fixedly welded on the top wall of the base 16. Springs 18 are provided above the four support columns 17, and connecting blocks 19 are fixedly installed at both ends of the springs 18. The connecting blocks 19 on the top side are fixedly welded to the screening drum 1, and the connecting blocks 19 on the bottom side are fixedly welded to the tops of the support columns 17. Through the cooperation of the support columns 17, springs 18 and connecting blocks 9, the screening drum 1 can be more easily vibrated on the base 16 with the cooperation of the vibration motor, thereby improving the vibration effect of the screening drum 1.

[0025] The side wall of the screening cylinder 1 is provided with three discharge ports 20 , to which a sealing door 21 is hingedly connected. The discharge ports 20 are convenient for guiding the screened rapeseed oil material out of the screening cylinder 1 .

[0026] Working principle: When the utility model is in use, the drive motor 11 is set to drive the turntable 12 to rotate. When the turntable 12 rotates, the rotating column 13 can be driven to rotate around the center of the turntable 12, so that the rocker 14 flips back and forth, and drives the push-pull rod 15 to move up and down, so that the lifting rod 6 can be lifted and lowered back and forth. During the reciprocating lifting process, the lifting rod 6 can be meshed with the gear 4 through the rack 7, so that the rotating shaft 3 can be reciprocated, so that the three screening nets 2 can be flipped back and forth, so that the rapeseed oil material can roll back and forth on the screening net 2 during screening, and screening is performed, which greatly improves the screening efficiency.
