Description

Technical Field

[0001] This utility model relates to the field of kiln technology, specifically to a quick-replacement structure for the inner wall of a kiln used for refractory sintering. Background Technology

[0002] Tunnel kilns are commonly used continuous firing equipment for firing building materials, ceramics, and ordinary refractory materials. With the development of high-temperature and ultra-high-temperature tunnel kilns, they have also become kilns for firing special refractory materials.

[0003] The existing publicly available technology, application number CN202323651863.9, describes a refractory sintering kiln, including a furnace body. A filter box is fixedly installed on the top of the furnace body, and a heat exchange box is fixedly installed on the top of the filter box. Exhaust pipes are fixedly installed on both sides of the top of the furnace body, and the other end of the exhaust pipes passes through and extends into the interior of the filter box. A filter screen is fixedly installed inside the filter box and near its top. Heat exchange pipes are connected through the top two sides of the filter box, and the top ends of the heat exchange pipes pass through the heat exchange box and are connected through the exhaust pipe.

[0004] Currently, existing kilns generate dust, slag, and residue during operation. These substances adhere to the inner walls of the kiln and the combustion device, affecting heat conduction and combustion efficiency, and damaging the refractory bricks. Therefore, regularly replacing the inner refractory bricks is one of the basic steps in kiln maintenance. Traditional replacement methods require shutdown, fan cooling, manual entry into the kiln to remove the inner lining refractory bricks, manual installation of new inner lining refractory bricks, baking and heating, and resumption of feeding, which takes 10 to 20 days. The long replacement cycle reduces equipment utilization and makes maintenance difficult, hindering rapid replacement and maintenance. Overall, the replacement operation is not ideal.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
