Drying roller dust gas handling system

The utility model provides an efficient, easy realization, be difficult for plug the pipe's drying roller dust gas handling system, include the cylinder body, set up in the discharge end of cylinder body for the discharging pipe of the ejection of compact and set up in the discharge gate of discharging pipe bottom, the top of discharging pipe is provided with out the dirt mouth, still includes the dust collector that is equipped with the air inlet on it, play dirt mouth on the discharging pipe through lead the dirt pipe with air inlet on the dust collector corresponds the intercommunication, that leads dirt pipe middle part highly is higher than this height of leading dirt pipe both ends, this design is compared with the direct horizontal pipeline that sets up of " one " font that adopts, and this design is difficult for piling up on the pipeline wall when carrying dust gas, is difficult for plug the pipe, improves its dust absorption efficiency, has reduced maintenance frequency and manufacturing cost.
