AI Technical Summary
In existing baghouse cleaning devices, fine dust can easily enter the nozzle during the cleaning process, causing blockages and affecting the cleaning effect.
The system employs a purge pipe structure with a drive component. The purge pipe is rotated by a drive motor, which directs the nozzle toward the filter bag. An air compressor is used for blowing and spraying. Combined with a sealed rotary joint and an air collection sleeve, the sealing effect is improved, preventing dust from entering the nozzle.
It effectively reduces the probability of fine dust entering the nozzle, improves cleaning efficiency and sealing effect, and ensures the normal operation of the jet cleaning device.
