FLAME-RETARDANT DEVICE OF A HOT WELL TANK, CAPABLE OF PREVENTING FIRE IN ADVANCE BY CONTROLLING TEMPERATURE USING A TEMPERATURE SENSOR IN A RAPID TEMPERATURE RISE

摘要

PURPOSE: A flame-retardant device of a hot well tank is provided to prevent fire using a flame-retardant plastic cover for the hot well tank.;CONSTITUTION: A flame-retardant device of a hot well tank comprises a body(1), a cover, a pipe heater(200), a temperature sensor(300), and a flame-retardant plastic cover. A water storing space is formed inside the body. The cover is joined to an opened upper side of the body, thereby closing the water storing space. The pipe heater and the temperature sensor are arranged in the body. The flame-retardant plastic cover includes an insulating material(400) surrounding a bottom surface and a side surface the cover. The flame-retardant plastic cover is formed in the inner periphery of the temperature sensor. The insulating material is formed of foamed polystyrene or foamed polyurethane.;COPYRIGHT KIPO 2013
