Dust collection device for corrugated paper printing press

Abstract

This invention relates to a dust collection device for a corrugated paper printing machine, comprising a machine body with a dust collection device mounted on its side. The dust collection device includes a filter bag assembly comprising a plurality of filter bags. Each filter bag has a first end communicating with the interior of the machine body and a second end communicating with a dust collection bin. An automatic de-clogging device is also included, comprising a differential pressure sensing unit electrically connected to and controlling the operation of a dust blowing unit. The dust blowing unit includes a main duct extending into a plurality of manifolds, each manifold having a ventilation nozzle communicating with each filter bag. The differential pressure sensing unit measures the pressure difference between the inlet and outlet pressures. When the pressure difference reaches a preset value, the dust blowing unit is activated, thus achieving automatic filter bag cleaning through sensing and control.

Claims

1. A dust collection device for a corrugated paper printing machine, comprising a machine body, a dust collection device provided on the side of the machine body, the dust collection device including a filter bag group, the filter bag group including a plurality of filter bags, the first end of each filter bag communicating with the interior of the machine body, and the second end communicating with a dust collection bin, characterized in that an automatic deblocking device is provided, the automatic deblocking device including a differential pressure sensing unit, and the differential pressure sensing unit is electrically connected to and able to control the operation of a dust blowing unit, the dust blowing unit including a main air duct, and the main air duct extending into a plurality of manifolds, each manifold being provided with a ventilation nozzle communicating with each filter bag.
