Cooling system of four-roller centrifugal machine

The utility model discloses a cooling system of a four-roller centrifugal machine. The cooling system comprises roller heads, a rotating mechanism and a cooling mechanism, an annular cooling cavity is formed in the roller head; an annular through groove is formed in the side wall, close to the rotating mechanism, of the roller head. An annular adapter is arranged in the annular through groove; the rotating mechanism is arranged on one side of the roller head and comprises a rotating shaft tube and a shaft tube shell; the roller head is driven to rotate; the cooling mechanism is arranged in the cooling cavity, comprises a cooling liquid pipeline and a spray head and is used for cooling the roller head. According to the cooling system of the four-roller centrifugal machine, the cooling liquid pipeline can be prevented from occupying the internal space of the rotating shaft pipe, the introduction amount of cooling liquid can be increased, the cooling effect is improved, and then the product quality is improved;
