A high-speed kneader for producing composite materials relates to the field of kneader technology and solves the problem of easy oxidation and performance degradation of composite materials during the kneading process in existing technologies. It includes a tank body, with a feeding tank connected to the bottom of the tank body. A
discharge pipe is connected to the lower end of the feeding tank. An inlet
pipe and a vacuum
pipe are connected to the upper side wall of the tank body. A rotating shaft is coaxially rotatably connected to the tank body. The lower end of the rotating shaft is disposed inside the feeding tank. An air inlet is opened on the bottom end face of the rotating shaft, and multiple air outlets are evenly opened on the top side wall of the rotating shaft. An
electric heating element is connected inside the rotating shaft, and multiple mixing blades are connected around the circumference of the rotating shaft. A material receiving plate is provided on the top of the feeding tank, and an air inlet pipe is connected to the side wall of the feeding tank. The beneficial effect is that it can inhibit the contact between materials and
oxygen, improving the performance stability of composite materials.
