This utility model relates to the field of composite
powder processing technology, specifically a mixing device for composite powders. It includes a tank
assembly, a stirring
assembly, and a mixing
assembly. The tank assembly includes a
mixing tank; the stirring assembly includes a first motor, a stirring shaft, and a stirring drum; the mixing assembly includes a second motor, a rotating shaft, and a
mixing chamber. Heating elements are installed on the inner side of the tank. A protective layer is connected to the inner wall of the
mixing tank. Stirring blades are connected to the outer wall of the stirring shaft, and a mixing rod is connected to the outer wall of the rotating shaft. When the first motor is started, the stirring shaft drives the stirring blades to rotate. The material is agitated and sheared by the stirring blades inside the stirring drum. Under
centrifugal force, some material moves towards the periphery of the stirring drum and enters the
mixing chamber through a filter screen. In the
mixing chamber, heat exchange occurs with the protective layer. Material that does not pass through the filter screen continues to be stirred inside the stirring drum, thus achieving material mixing in a cyclical manner.
