Description

Technical Field

[0001] The utility model relates to the technical field of tunnel furnaces, in particular to a tunnel furnace with a turnover structure. Background Art

[0002] A tunnel furnace is a device used for industrial heating and heat treatment. Its structure is similar to a long and narrow tunnel, hence its name. A tunnel furnace is usually made of bricks, concrete or metal, and has one or more combustion chambers and heating areas inside. The working principle of a tunnel furnace is to burn fuel (such as natural gas, liquefied petroleum gas, diesel, etc.) in a combustion chamber to generate high-temperature combustion gas, and then pass these hot gases through the heating area in the furnace to heat the materials or products to be processed. Publication No. CN208794969U discloses a tunnel kiln, which combines traditional silicon carbon rod heating with heating water tank and microwave source system heating. The heating rate is fast, and each H-shaped channel and compartment in the heat dissipation zone are connected and the air flow rate is accelerated by a blower to quickly cool down. However, during the firing process of high-temperature fired ceramic workpieces, since the tunnel of the tunnel kiln does not have a flipping structure inside, a few ceramic fired workpieces may be heated unevenly, which affects the overall firing efficiency of the ceramic fired workpieces inside the tunnel. Therefore, it needs to be improved. Utility Model Content
