AI Technical Summary

Technical Problem

In existing industrial fans with exhaust gas filtration functions, activated carbon filter elements are prone to clogging, resulting in poor filtration performance. Furthermore, cleaning is difficult and requires manual disassembly and maintenance, which affects production efficiency.

Method used

The activated carbon filter cartridge is automatically cleaned by a mode switching mechanism and a dust removal auxiliary mechanism. The backflow airflow removes blockages, and the dust collection mechanism collects dust, reducing the difficulty of cleaning.

Benefits of technology

It enables automatic cleaning of activated carbon filter cartridges, avoiding manual operation and downtime maintenance, improving production efficiency and filtration effect, and ensuring stable operation of the equipment.

Abstract

The invention belongs to the technical field of industrial fans, and particularly relates to an industrial fan with a waste gas filtering function, which comprises a bottom plate with universal wheels at the bottom, a bottom box is fixedly connected to the outer wall of the top of the bottom plate through screws, and a top box is fixedly connected to the outer wall of the top of the bottom box through screws. A ventilation cylinder is fixedly connected to the side, located on the bottom box, of the outer wall of the top of the bottom plate through screws, and a first air suction main pipe and a backflushing pipe communicate between the ventilation cylinder and the bottom box. The mode switching mechanism, the ash removal auxiliary mechanism and the dust collection mechanism are mechanically integrated, the integrated function of efficient filtering and automatic ash removal is achieved, the mode switching mechanism can ensure smooth switching of the filtering mode and the ash removal mode, the ash removal auxiliary mechanism and the dust collection mechanism can efficiently remove filter element blockages, centralized collection of dust is achieved, and the dust removal efficiency is improved. The synergistic effect of all the parts not only maintains the long-term stable filtering effect, but also solves the cleaning problem of the activated carbon filter element.
