Description

Technical Field

In the prior art, the hot air filter cylinder and the hot air duct are connected in rotation through a seal. The filter cylinder is driven to rotate relative to the hot air duct by a driving mechanism, and the rotating filter cylinder is cleaned by a brush or scraper arranged on the outside of the hot air filter cylinder. Since there is relative rotation between the filter cylinder and the hot air duct, the seal between the two is easy to wear. When the seal is worn, the particles in the hot air flow can leak into the hot air pipeline, and it is easy to form scale on the fan impeller and the inner wall of the hot air duct; and the particles on the surface of the filter cylinder are easy to adhere to the mesh of the filter cylinder under the rubbing of the brush or scraper, causing the mesh of the filter to be blocked, so that the effective use area of ​​the filter cylinder is reduced and the flow rate of the hot air flow is reduced. When the mesh of the filter drum is clogged, the machine needs to be stopped to clean the filter drum manually.
