This application provides an intermittent
refractory firing
kiln, relating to the field of
kiln technology. An intermittent
refractory firing
kiln includes an outer shell, the interior of which is undivided. A conveying component is installed inside the outer shell. Multiple sets of flow-disrupting mechanisms are symmetrically arranged at the top of the sidewall of the outer shell. Each flow-disrupting mechanism includes an active telescopic component, the
piston end of which is drivenly connected to a
fan blade. The extension length of the active telescopic component is related to the rotational speed of the
fan blade. A return flow channel is provided on the outer shell. As the material's conveying speed increases within the kiln, the
fan blade tilts downward and increases its rotational speed, accelerating gas circulation within the outer shell, reducing potential temperature dead zones on the material, and accelerating firing. The fan blades create
airflow circulation within the outer shell, enhancing temperature stability, reducing local temperature differences, maintaining a consistent temperature throughout the entire outer shell, and allowing for overall
temperature control, thus improving energy efficiency.
