Description

Spiral oil press is used in rapeseed oil production Technical Field The invention relates to the technical field of screw oil presses, in particular to a screw oil press for rapeseed oil production. Background The main part of the screw oil press is a press chamber, which consists of a press cage and a screw shaft rotating in the press cage. The working process of the device utilizes the continuous rotation of the screw shaft, and the volume of the space of the press chamber is continuously reduced to generate a pressing action along with the reduction of the lead or the gradual increase of the diameter of the root circle, so that the pressed grease flows out from the gap of the press cage in a pressing way, and meanwhile, residues are pressed into chip-shaped cake slices, and the chip-shaped cake slices are continuously discharged from the tail end of the pressed grease. In the existing spiral oil press, the pressed slag is discharged from a slag hole in the oil pressing process, but the slag still contains a certain amount of grease, and if the recovery treatment is not performed, the waste of the grease can be caused. At present, although some devices have attempts to squeeze slag again, certain limitations exist, such as the need to stop the whole device to perform slag pushing operation, thus reducing the working efficiency. In addition, in the process of oil extraction, a slag hole and an oil outlet are easy to be blocked. For the tap hole, slag may gradually coagulate into pieces as the oil extraction process proceeds, resulting in clogging of the tap hole. The oil outlet is blocked possibly because a small amount of dregs are mixed in the extracted oil, and the dregs accumulate in the oil outlet channel to influence the smoothness of oil outlet. Based on the scheme, the spiral oil press for rapeseed oil production is provided.
