The container system of our company’s explosion-proof electric heater is imported and exported, and the external coated insulation material is equipped with an explosion-proof chamber. The structure is simplified, and the process is convenient, and the manufacturing cost can be reduced. The explosion-proof electric heater is shown in the figure below, and one end of the container body 5 has an inlet 7, and there is an outlet 4 above, and the outer coated silicate insulation cotton 1 1. The explosion-proof chamber 1 3 is located at the other end of the container body 5, and between the two fixed welding between the two, the two-spaced separated spacer 1 is fixed between the various sleeves, which can be enhanced to the sleeve. Further, portable electric heater a gas-cooled convection flow path is formed. The electric heating device 6 is penetrated from the container body 5 (by the flange 3, the insulation pad 2, and the separator 1), each sleeve is passed through a electric heater device, mutual The gap between 0.5 mm can prevent fluid media from forming a heat convection thereon, thereby isolating heat and avoids dissemination. The wire is penetrated by the explosion-proof chamber 13, and the end of the heat transfer device 6 is electrically connected. The container body is adjacent to one end flange 3 of the explosion-proof chamber to fix the insulation housing made of white iron skin, which is filled in the outer casing 2, thereby replacing the water cooled chamber, which is both insulated and heat loss.
Our explosion-proof electric heater can suppress the temperature of the explosion-proof chamber to control temperature, thereby ensuring that the PVS insulated wire is not damaged by high temperature while significantly reduces heat loss, and the energy saving effect is obvious. It has a simple structure and a decrease in manufacturing cost. In addition, the explosion-proof electric heater of our company has other advantages, for example, in addition to aluminum silicate, insulation materials can also be mullish, glass fiber, asbestos, etc. The technical solution formed by equivalent replacement or equivalent transform is within the protection range.
