Abstract:
A plasma cutting table includes an open frame table, a movable bridge extending across the table and a gas evacuation system. A pair of opposed plenums are positioned adjacent the table on opposite sides of the table extending along the general length of the table with each plenum forming a channel. A hopper extends across an underside of the table and is attached to the bridge to be movable relative to the table with the bridge. A pair of conduits extend from the hopper to each channel, respectively, wherein each conduit is slidably positioned in the channel formed by the respective plenum. A flexible sealing member is attached to an upper side of each plenum forming a seal between the conduit and the plenum. The flexible sealing member includes a pair of strips of flexible material extending the length of the plenum on opposed sides of the plenum, wherein the conduit is received between the pair of strips of flexible material. A vacuum pump is connected to the pair of plenums through a pair of chambers each including a plurality of baffles.
