Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel kilns, and in particular relates to a fast unloading device for a high-temperature tunnel kiln. Background Art

[0002] Tunnel kiln is a tunnel-like kiln built with refractory materials, thermal insulation materials and building materials, equipped with kiln cars and other vehicles. It is a modern continuous firing thermal equipment. Tunnel kiln is widely used in the roasting production of ceramic products, and is also used in metallurgical industries such as abrasives. Tunnel kiln is generally a long straight tunnel with fixed walls and vaults on both sides and the top, and kiln cars running on the tracks laid at the bottom. The combustion equipment is located on both sides of the middle of the tunnel kiln, forming a fixed high-temperature zone - the firing zone. The high-temperature flue gas generated by the combustion flows along the tunnel to the kiln head under the action of the chimney or induced draft fan at the front end of the tunnel kiln, and gradually preheats the products entering the kiln.

[0003] In the existing technical solution, workpieces need to be transported by rails and kiln cars, and they need to be unloaded after being transported to the inside of the tunnel kiln.
