APPARATUS FOR ADJUSTING THE TEMPERATURE OF TOP COVER OF A ROTARY HEATER

摘要

A top plate temperature control apparatus of rotary heater having : a top plate(110); a fixing plate(3) having a convex part(1) in its center and suspending a red heater(108) in its lower part and fixing a sub-heat insulation plate(2) in its upper part; a space(4) formed between a top plate(110) and a fixing plate(3); a heat insulation plate(5) elevated in a circumference of a sub-heat insulation plate(2); an elevating means(20) elevating a heat insulation plate(5); and a driving means(30) driving an elevating means(20); is disclosed. Thereby, it is possible to quickly heat the object to be heated by elevation the temperature of the top plate in weak combustion of the rotary heater.
