AI Technical Summary
When overhauling an insertion dust collector, the belt conveyor needs to be shut down, which leads to production interruption and losses. Existing technology cannot clean the dust collector filter bags without shutting down the machine.
Design a switching valve structure for a dust collector, in which multiple air-sealing plates rotate synchronously to open and close the windproof housing, preventing dust from entering the dust collector and allowing the filter bags to be cleaned during the operation of the conveying equipment.
It enables cleaning of dust collector filter bags without shutting down the system, reducing production interruptions and losses. Its compact structure also reduces space requirements.
