[0026] In summary, this microwave vertical high-temperature furnace with a smoke exhaust structure, by installing a sleeve 5 outside the smoke exhaust pipe 4 and incorporating a high-temperature resistant centrifugal fan 6, can actively and quickly exhaust the smoke and waste gas generated in the furnace cavity. Compared with the traditional top natural smoke exhaust method, this significantly improves smoke exhaust efficiency and effectively avoids problems such as unstable furnace pressure and damage to microwave components caused by waste gas retention. Simultaneously, the high-temperature resistant ceramic coating and spiral guide protrusions on the inner wall of the smoke exhaust pipe 4 not only resist high-temperature corrosion but also guide the airflow smoothly, further improving smoke exhaust efficiency. By setting up the positioning component 7, pulling the left and right locking plates 74 disengages them from the positioning ring 71, allowing the sleeve 5 to be removed from the smoke exhaust pipe 4 for easy maintenance of the high-temperature resistant centrifugal fan 6, thus improving efficiency. The device's practicality is enhanced by the installation of a stabilizing component 3. This component, through the coordination of an electric push rod 32, a slider 33, and a connecting rod 35, drives the sliding plate 34 and the stabilizing block 36 to descend, ensuring the stabilizing block 36 makes tight contact with the ground and firmly fixes the high-temperature furnace body 1. This effectively resists the risk of displacement caused by uneven ground or microwave vibration, significantly improving stability compared to traditional mobile high-temperature furnaces. This further enhances the device's practicality and solves the problems of traditional microwave high-temperature furnaces, which often use simple top exhaust ports and lack efficient exhaust power, affecting flue gas emission efficiency. Furthermore, while some high-temperature furnaces are equipped with casters for easy workstation adjustments, the lack of a reliable stabilizing structure during operation makes the equipment prone to displacement due to uneven ground or microwave vibration, affecting its usability.
