Description

Technical Field

[0001] The utility model relates to the technical field of rapeseed oil pressing, in particular to a rapeseed oil extraction mechanism of a rapeseed oil press. Background Art

[0002] When the oil press is in operation, processed oil enters the press chamber from the hopper. The rotation of the screw pushes the oil embryo inward, causing the oil to be squeezed. Because the oil embryo is in motion within the press chamber, the high pressure in the chamber creates significant friction between the embryo and the screw, and between the embryo and the chamber. This creates friction between the embryo and the oil, causing relative motion. Furthermore, because the screw's diameter gradually increases and its pitch gradually decreases, as the screw rotates, the threads force the oil embryo to both push forward and flip outward. Simultaneously, the oil layer near the screw's threads rotates with the press shaft.

[0003] After searching, the utility model patent of China Patent Publication (Announcement) No. CN213680570U discloses a rapeseed oil extraction mechanism of a rapeseed oil press, which is roughly described as comprising a shell, a pressing mechanism is arranged inside the shell, and an extraction mechanism is arranged at the lower end of the shell. When in use, the second motor drives the threaded rod to rotate, and the threaded rod drives the scraper to rotate. The scraper moves back and forth to scrape the oil gathered at the bottom of the oil outlet to prevent adhesion. The oil falls into the oil collecting tank from the oil outlet, and the rapeseed oil gathers in the oil collecting tank, gathers and flows out from the bottom groove at the bottom of the oil collecting tank, and is finally discharged through the oil outlet. When the scraper moves toward the oil outlet, the oil will be discharged. When the scraper moves, the scraped oil flows into the bottom trough through the guide groove and is pushed toward the oil outlet by the rotating plate. When the scraper returns, the scraped oil is guided into the bottom trough through the guide groove on the other side. When the rotating plate encounters resistance in the bottom trough, it will rotate along the rotating rod so that the oil can flow normally in the bottom trough. However, the above device still has certain shortcomings. For example, the filter screen in the above device is arranged inside the shell, which is not convenient for people to clean the filter screen. After a period of use, a lot of rapeseed residue will adhere to the filter screen, which may cause the filter screen to be blocked, thereby reducing the rapeseed oil processing efficiency. For this reason, we propose a rapeseed oil extraction mechanism for a rapeseed oil press. Utility Model Content
