Conveyor powder coating drying device using high-efficiency explosion-proof far-infrared sheath heater and drying method using the same

摘要

The present invention relates to a high-efficiency explosion-proof far infrared ray structure with economical efficiency, environmental friendliness, excellent paint quality and industrial safety through development of a far infrared ray sheath heater and a heater frame and system control with an explosion-proof structure ensuring oxidation stability in a high temperature conveyor powder coating dryer. A discharging unit 200, a surface temperature measuring unit 300, a temperature controlling unit 400, a transferring unit 500, and a transferring unit 500. The inside temperature measuring unit 100, the discharging unit 200, the surface temperature measuring unit 300, A function of drying the drying body by generating heat and far-infrared rays from the sieve heater 630 in a conveyor powder coating drying apparatus using a sieve heater including a drying unit 600, a cooling unit 700 and a power control unit 800 (Ex d Ⅱ B T1) in accordance with the Industrial Safety and Health Law, and the measurement is performed through the internal temperature measuring unit 100 provided in the drying section The temperature of which is controlled according to the temperature. In the heating zone, which is divided into a plurality of zones, which are divided into a plurality of zones, the drying object of the drying subject is allowed to absorb a large amount of heat, The drying unit 600 is designed to require relatively lower Kw than the inlet unit because it is a condition that heat already contained in the substance to be dried is maintained in the latter half of the middle part, and the temperature control unit 400 The power control unit 800 controls the amount of power supplied to the discharge unit 200, the transfer unit 500, the drying unit 600, and the cooling unit 700. The internal temperature measurement unit 100 and the surface When the temperature of each of the plurality of zones is sensed through the temperature measuring unit 300, an amount of power of the power control unit 800, which supplies the sensed temperature to the drying unit 600 through the temperature control unit 400,The temperature control unit 400 may control the temperature of the drying unit 600 to be selectively supplied to each of the plurality of zones of the drying unit 600, And a drying device controller (900) for shutting off the power supply when the temperature of the heat transmitted to the object to be dried is out of a preset value (threshold value).
