Water cooling system of internal mixer

The utility model relates to a water cooling system of an internal mixer. Internal mixer comprising an internal mixer body, wherein an internal mixing chamber is arranged on the internal mixer main body; a cooling cavity is formed in the internal mixing chamber, a water inlet pipe and a water outlet pipe are arranged on the two opposite sides of the internal mixing chamber and communicated with the cooling cavity, a first water pump is connected to the end, away from the internal mixing chamber, of the water inlet pipe, the water inlet end of the first water pump is connected with a cold watertank through a pipeline, and the water outlet pipe is communicated with the cold water tank. The first water pump conveys cold water in the cold water tank to the cooling cavity, the cold water flowsthrough the cooling cavity and cools the internal mixing chamber, and the phenomenon that the temperature of the internal mixing chamber is too high can be effectively avoided. 本实用新型涉及一种密炼机水冷系统，包括密炼机主体，所述密炼机主体上设有密炼室，所述密炼室上设有冷
