1) Adding base oil into an oil pool of the oil refining pool, and heating the base oil after the base oil is added;
2) Feeding, refining oil and separating oil residues, when the bottom oil is heated to a set temperature, starting a stirring wheel, a distributing hopper, a first conveying chain net and a second conveying chain net, and continuously enabling animal scraps to fall on the second conveying chain net from the storage hopper through the stirring wheel, the distributing hopper and the first conveying chain net in sequence; in the continuous feeding process of the first conveying chain net and the second conveying chain net, the high-temperature hot gas above the oil refining pool completes one-time oil refining on animal offal on the first conveying chain net and the second conveying chain net in the first channel and the second channel under the flow guiding effect of the cross-flow fan; animal offal after primary oil refining falls into the oil refining pool along with the movement of the second conveying chain net, the animal offal slowly moves from the feeding end of the oil refining pool to the slag discharging end of the oil refining pool along with the scraping plate on the second conveying chain net in the oil refining pool, and finally becomes oil liquid and oil slag in the whole movement process, so that secondary oil refining is completed; meanwhile, in the secondary oil refining process, oil residues at the slag outlet end of the oil refining pool are scraped to a discharge chain net under the action of a scraper on a second conveying chain net, and the discharge chain net conveys out the oil residues, so that oil residue separation is completed;
3) And (3) oil is discharged, wherein the oil is discharged along with continuous oil refining, when the liquid level of the oil in the oil refining tank reaches the oil outlet at the slag outlet end of the oil refining tank, the oil automatically flows out of the oil refining tank from the oil outlet, and the oil in the first oil receiving tank and the second oil receiving tank is identical to the oil discharging principle in the oil refining tank.
Other than the technical features described in the specification, all are known to those skilled in the art.
While the preferred embodiments and examples of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited to the embodiments and examples, and it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit of the present invention, and the scope of the invention is also defined by the appended claims.
