The utility model discloses a heating device for
glass manufacturing, which is characterized in that one side of a device main body is connected with an
electric wire in an embedded manner, the outer side of the
electric wire is connected with a heat insulation mechanism in an embedded manner, the upper end of the heat insulation mechanism is connected with a water filling
nozzle in an embedded manner, and the bottom of the water filling
nozzle is provided with a water filling
nozzle which is connected with the heat insulation mechanism in a penetrating manner; and a heating coil is arranged on the other side of the heat insulation mechanism. By arranging the heat insulation mechanism and the mounting port, the heat insulation mechanism can insulate high-temperature
radiation, and meanwhile, cooling water on the inner side of the heat insulation mechanism can cool the outer surface of the heat insulation mechanism, so that the
electric wire can be prevented from being baked by heat
radiation, and the situation that the electric wire is damaged due to long-time heating is avoided; and after cooling water in the heat insulation mechanism is evaporated at a high temperature,
water vapor can be input into the gas
storage tank, so that the evaporated cooling water in the heat insulation mechanism can be reasonably recycled, and waste of
water resources is avoided.
