Rostone workshop dust collecting system

The utility model provides a rostone workshop dust collecting system, belongs to rostone processing production field, and including a plurality of workstations, a plurality of dust cage, dust absorption wind channel, setting tank, negative -pressure air fan, sediment pond, suction pump, characterized by, dust cage establish on workstation upper portion, and the dust absorption wind channel connects gradually dust cage, setting tank, negative -pressure air fan, sediment pond, and suction pump inlet connection deposits the pond, and a plurality of shower heads of establishing deposiing the pond top are connected to the exit end. Dust that the workstation produced reachs the setting tank by the dust cage through the dust absorption wind channel and tentatively deposits, then is blown to by negative -pressure air fan and deposit in deposiing the pond, and the water that the suction pump extraction deposits the pond carries out secondary precipitation through all -round the spraying of shower head, and this simple structure of system can effectually prevent dust pollution, provides the assurance for the staff is healthy.
