[0002] Industrial furnaces are equipment used for heating, melting, roasting or other industrial processes. Industrial furnaces are usually made of metal or ceramics and can use various fuels such as natural gas, coal, oil, etc. to provide heat energy. Industrial furnaces are widely used in various industries such as metallurgy, chemical industry, glass, ceramics, food, etc., for heating raw materials, melting metals, sintering ceramics and other processes.

[0003] After consulting the literature, it is learned that the existing patent (publication number: CN214120810U) discloses a high-precision temperature-controlled industrial furnace, including a furnace body, a furnace door is opened at the lower front side of the furnace body, and a mounting frame is vertically fixedly connected to the front side of the furnace body. A rotating rod is rotatably arranged laterally on the top of the inner wall of the mounting frame, and first bevel gears are arranged at both ends of the surface of the rotating rod. A motor for driving the rotating rod to rotate is arranged at the top of the mounting frame, and a threaded rod is rotatably arranged vertically at both ends of the inner cavity of the mounting frame. The threads on the surfaces of the two threaded rods are in opposite directions, and a second bevel gear meshing with the first bevel gear is arranged at the top of the threaded rod, and a threaded sleeve is threadedly connected to the surface of the threaded rod, and a baffle is laterally fixedly connected between the inner ends of the two threaded sleeves.

[0004] However, the above-mentioned prior art still has some shortcomings in actual use: when the industrial furnace is working, if the raw materials or feed of the industrial furnace contain moisture, it will release water vapor during the heating process. These water vapors may adhere to the inner wall and the observation window provided therein. If these water vapors condense on the observation window, the observation field of view will become blurred, which will greatly affect the staff's observation of the situation inside the furnace and has low practicality. In view of this, we propose an industrial furnace that is easy to observe to solve the above problems. Utility Model Content
