[0019] The utility model embodiment provides a rapeseed oil extraction device, such as Figure 1-3 As shown, it includes a separation box 1, the left and right sides of the separation box 1 are connected with an oil inlet pipe 2, the top of the separation box 1 is installed with a purification box 3, the right side of the purification box 3 is connected with an oil outlet pipe 4, the top of the purification box 3 is connected with a feeding pipe 5, a fixed cylinder 6 is installed at the top center of the separation box 1, the fixed cylinder 6 extends to the inside of the purification box 3, a filter plate 7 is installed on the top of the fixed cylinder 6, a first motor 8 is installed on the top of the purification box 3, the output shaft of the first motor 8 is connected with a connecting rod 9, the connecting rod 9 passes through the filter plate 7 and extends to the bottom thereof and is connected with a scraper 10, the connecting rod 9 is connected to the filter plate 7 through a bearing, the scraper 10 is fitted with the lower surface of the filter plate 7, a scraper frame 11 is installed on the side of the connecting rod 9, and the scraper frame 11 is fitted with the inner wall of the purification box 3, By providing a fixed cylinder 6 and a filter plate 7, when the device is used, rapeseed oil with impurities enters the interior of the separation box 1 from the oil inlet pipe 2, and then flows into the top of the filter plate 7 from the top of the fixed cylinder 6 in an infiltration manner. The feeding pipe 5 adds chemical substances to purify the rapeseed oil. The rapeseed residue remains in the separation box 1 under the action of gravity, and will not accumulate on the surface of the filter plate 7. This arrangement can solve the problem of clogging of the filtration system in the extraction device. By providing a scraper 10 and a scraper frame 11, the first motor 8 is started to drive the connecting rod 9 to rotate, and the scraper 10 and the scraper frame 11 rotate at the same time. The scraper 10 scrapes and brushes the lower surface of the filter plate 7 to avoid some residues clogging the mesh, and the scraper frame 11 can prevent rapeseed oil from remaining in the purification box 3.
