Calcination device for heat-resistant casting processing

The invention discloses a calcining device for heat-resistant casting processing, relates to the technical field of casting processing and calcining, and aims to solve the problems that flue gas generated by calcining of an existing calcining device for heat-resistant casting processing contains impurities such as silicate, an isolation net for filtering the impurities cannot be automatically cleaned, and the impurities are adsorbed on the isolation net and are difficult to clean after a long time. According to the technical scheme, the device comprises a calcining box body and a purifying box, the top side of the calcining box body fixedly communicates with a smoke exhaust pipe, and the end, away from the calcining box body, of the smoke exhaust pipe fixedly communicates with a filtering box. The device is reasonable in design and easy to operate, impurities in calcining flue gas can be filtered, an isolation net can be automatically cleaned, the calcining flue gas can be efficiently purified, pollution to t
