the second branch system is used for separating second crude oil and second slag from the waste residue oil;

a pressing assembly for pressing the first and second slags;

and the flushing component is used for flushing the swill oil and/or the floating grease entering the first branch system.

2. The illegal cooking oil classification system according to claim 1, wherein the first branch system comprises a first receiving hopper, an impurity remover, a first slag remover, a separator and a first storage tank which are arranged in sequence, the first slag comprises coarse slag and fine slag, the first receiving hopper is used for storing the swill oil and/or the floating grease, the impurity remover is used for separating the coarse slag and the coarse oil from the swill oil and/or the floating grease, the first slag remover is used for separating the fine slag and the fine oil from the coarse oil, the separator is used for separating the first crude oil from the fine oil, and the first storage tank is used for storing the first crude oil.

3. The illegal oil classification system according to claim 2, wherein the first subsystem further comprises a heating tank disposed between the first slag remover and the separator, the heating tank being for heating the fine oil liquid.

4. The illegal cooking oil classification system according to claim 3, wherein the first branch system further comprises a coarse oil tank and a fine oil tank, the coarse oil tank is located between the skimmer and the first slag remover, the fine oil tank is located between the first slag remover and the heating tank, the coarse oil tank is used for storing the coarse oil, and the fine oil tank is used for storing the fine oil.

5. A illegal oil sorting system according to claim 4, characterized in that the first branch system further comprises a first crude oil tank between the separator and the first tank, the first crude oil tank being adapted to buffer the first crude oil.

6. The illegal cooking oil classification system according to claim 5, wherein the first branch system further comprises a first conveying device provided between the first receiving hopper and the shaker, between the crude oil tank and the first slag remover, between the fine oil tank and the heating tank, between the heating tank and the separator, and between the first crude oil tank and the first storage tank.

7. The system of claim 2, wherein the skimmer and the first skimmer are both in communication with the flushing assembly for feeding a flushing liquid into the skimmer and the first skimmer.
