AI Technical Summary
The existing dust collection method of the free-flow cleaning fan results in insufficient negative pressure, poor dust collection effect, high equipment failure rate, increased energy consumption, and easy clogging of the suction pipe, which can damage the drive belt and motor.
The main suction tube is divided into a first branch tube and a second branch tube, with an independent suction box installed in the middle. The suction box contains a filter plate. Each machine can independently suction dust through connectors and installation mechanisms. The filter plate can be quickly disassembled and cleaned.
It improved the equipment's failure rate and production efficiency, reduced energy consumption, ensured the stability and cleaning effect of vacuuming, and reduced equipment maintenance.
