Description

Technical Field

[0001] The utility model relates to the technical field of heat-insulating bridges of oven inspection doors, in particular to a heat-insulating bridge structure of oven inspection doors. Background Art

[0002] The drying and curing furnace for coating is used to dry the moisture of the workpiece after pre-treatment or to cure the paint after spraying. The temperature inside the furnace is generally about 80℃~300℃. In order to facilitate maintenance, inspection doors need to be arranged at the locations where heating elements and hot air circulation elements are installed.

[0003] Existing inspection doors are generally composed of door frames and door panels. During use, the door body needs to be installed inside the oven first, and then the multi-stage bolts and nuts are adjusted to lock the door body. The operation is cumbersome and cannot meet the needs of different usage environments and different ovens. Since the door frame is made of metal plates or profiles welded as a whole, the thermal conductivity of the metal is relatively high, which will form a thermal bridge between the high-temperature area inside the furnace body and the low-temperature area outside, accelerating the heat dissipation of the oven and increasing the energy consumption of the equipment. In order to reduce the damage caused by this phenomenon, an insulating asbestos board is often installed directly behind the door body. As the insulation work continues, when the insulating asbestos board is worn out, the entire door body needs to be replaced, resulting in a waste of resources. Therefore, we urgently need an insulating thermal bridge structure for an oven inspection door to solve the above problems. Utility Model Content
