[0024] The support platform 1 provides a location for the installation of the cyclone dust collector 5 and the bag dust collector 2 on the top. The cyclone dust collector 5 rotates the dust-containing airflow, separates the dust from the gas by centrifugal force, and then causes the dust to fall by gravity, thereby processing the dust-containing gas.
