Description

Technical Field

[0001] The utility model relates to the technical field of tunnel furnaces, in particular to a single-channel double-push-plate tunnel furnace. Background Art

[0002] A tunnel furnace is a tunnel-type mechanical equipment that bakes food through heat conduction, convection, and radiation. It is widely used in food, printing, electronics, electromechanics, automobiles, acrylic molds, instruments, metal products, LED, LCD, touch screens, glass and other industries. It is used for baking, drying, curing, drying and other process. The advantages of tunnel furnaces include wide adaptability, low energy consumption, and high fuel utilization rate. However, there may also be disadvantages such as relatively low production efficiency and high requirements for the external environment. The furnace body of a tunnel furnace is generally long, with a minimum of 6 meters and a length of 60 to 80 meters. The baking chamber is a long and narrow tunnel with a width of generally 80cm to 140cm. There is a continuously operating conveying system in the tunnel. The food moves relative to the electric heating element or direct-burning combustion rod through the conveying chain plate, steel belt or mesh belt, thereby completing the work of uniform baking and conveying.
