AI Technical Summary
The nozzles of existing coal shed spray dust removal systems are prone to clogging due to dust pollution, and maintenance is inconvenient, affecting the dust removal effect.
A protective cover and a semi-circular sealing cover are installed outside the spray pipe. The rotation of the sealing cover is controlled by a drive motor to close the nozzle and prevent dust pollution. At the same time, a nozzle cleaning component is installed to wipe away residues and simplify maintenance.
It effectively prevents nozzle clogging, restores dust removal efficiency, facilitates daily maintenance, and improves the reliability and maintenance efficiency of the spray system.
