Leaching oil extraction technology

Leaching oil extraction technology, extraction of oil extraction equipment is a kind of professional equipment, it can be in thedebris and grease filter to exclude unwanted material, thereby producing the crude oil we need. Waste clay leaching oil extraction process is a waste edible oil industry after bleaching clay leaching oil extraction process, characterized in that it comprises the following steps: 
1, the preparation: the Lantau waste clay, ceramic clay, gypsum powder, calcium four samples of raw materials, according to the percentage by weight, wherein the waste clay accounted for 82% ~ 94% by weight of the sum of four kinds of raw materials, said ceramic clay accounting for 1.5% ~ 4.5% by weight of the sum of four samples of raw materials, said gypsum powderaccounted for 2% to 8% by weight of the sum of four kinds of raw materials, said calcium accounts for 2% to 6% by weight of the sum of four kinds of raw materials; According to 1.8 to 2.4 times the weight of the aforementioned four kinds of raw materialsand the Lantau Airport solvent oil;

2, mixing: the step of a ceramic clay, the gypsum powder and the calcium was poured into the mixer according to the aforementioned proportion sufficient stirring, followed by stirring for 2 ~ 8 minutes; 
3, and then mixing: the solvent in step 1 and then the waste oil, and stirred well within the clay according to the above ratio into said mixer, mixing for 10 to 30 minutes, to obtain a mixed material; 
4, the precipitate: the mixed material natural sedimentation, settling time of 50 to 80 minutes, and finally to obtain a precipitate, and the precipitate floating on top of the mixed oil; 
5, circulation evaporator: lessons sediment above mixed oil into the evaporator, circulating evaporator until a qualified crude oil.
