AI Technical Summary
The existing preheater's material spreading device has a single operation, which cannot ensure the uniform spreading of materials, resulting in low preheating efficiency.
A fixed flange is used to fix the spreading pipe to the feed inlet of the preheater. The dispersing motor drives the drive shaft and dispersing plate to rotate at high speed. The top shielding cap prevents material from entering the motor, realizing a double dispersing operation and improving the uniformity of the material.
The design of the double dispersion plate improves the uniform distribution of materials in the preheater and enhances the working efficiency of the preheater.
