A ventilator slidable dust-seal device

Abstract

The utility model relates to the technical field of industrial ventilation equipment, especially a ventilator slidable dust absorption sealing device, it includes sealing body, sealing body installs on the casing through the pressing plate mechanism, a plurality of sealing rings are connected with the sliding in sealing body, there is buffer gap between a plurality of sealing rings, still exists compensation groove between sealing body and sealing ring. The application has when the sealing ring expands due to the setting of buffer gap and compensation groove makes the expansion of sealing ring has space, further realizes the sliding of sealing ring in sealing body, and due to the setting of a plurality of sealing rings makes sealing ring still can play the sealing effect, further reduces the probability of damage caused by sealing ring expansion extrusion, further reduces the effect of the probability of ventilator air leakage and dust leakage.
