AI Technical Summary

Technical Problem

In existing technologies, when horizontally arranged filter elements are self-cleaning, dust can easily fall directly onto the filter element below, resulting in incomplete cleaning of the lower filter element, shortening its lifespan and increasing maintenance costs.

Method used

The filter element is designed to be rotatable, with a telescopic plate installed under each filter element. During self-cleaning, the telescopic plate extends to form a receiving surface to catch the dust that falls off. After self-cleaning is completed, it is automatically cleaned to ensure that the self-cleaning of each filter element is not disturbed.

Benefits of technology

It effectively disperses and cleans dust, reduces its impact on the filter element below, ensures thorough self-cleaning of the filter element, extends the filter element's lifespan, and reduces maintenance costs.
