Baffle plate assembly

摘要

A baffle plate assembly for reducing the amount of corrosive liquid contained within a railroad car from contacting a pressure relief valve connected to the railroad car. The baffle plate assembly includes a baffle body having one end connected to an upper plate and the other end connected to a lower plate. The baffle body includes a plurality of slotted openings and radially extending downwardly sloped drainage openings. The lower plate includes a radially extending downwardly sloped drainage surface that further includes a plurality of channels for draining liquid out of the baffle body. The baffle plate assembly is connected to the railroad car adjacent to the pressure relief valve such that air and/or other gases pass through the baffle plate assembly and then the pressure relief valve. Air and/or other gases pass from within the railroad car through the plurality of slotted openings defined in the baffle body into an interior chamber of the baffle body. The air and/or other gases then pass from the interior chamber of the baffle body to the pressure relief valve. The slotted openings reduce the amount of corrosive liquid passing through the baffle plate assembly as a result of splashing and sloshing of the corrosive liquid within the railroad car. Corrosive liquid that does enter the interior chamber of the baffle body drains out of the interior chamber of the baffle body through the plurality of radially extending downwardly sloped drainage openings and lower plate channels.
