AI Technical Summary
In existing rotary dryers, the raw materials inside are difficult to dry evenly and fully during the drying process, resulting in poor drying effect.
An interactive rotary uniform temperature raw material drying device was designed. By setting a rotating mechanism inside the drying cylinder, including a rotating shaft, a sleeve, a pushing component and a stirring blade, the pushing component is moved by the opposite rotation direction of the threaded sleeve and the threaded section, which increases the contact area between the raw material and the inner wall of the drying cylinder. The stirring blade disperses the raw material, and the use of heating chamber and air holes achieves uniform heating and drying.
This achieves uniform contact between the raw materials and the inner wall of the drying cylinder, improving drying efficiency and uniformity, and ensuring that the materials are fully dried.
