Abstract
A method and apparatus for improved in-car slurrying of dry bulk powder in hopper cars is disclosed. The individual hopper car compartments have ports in the bottom therein for admitting air under pressure and water to form the slurry. The apparatus of this invention includes an open mesh disposed across the upper portion of the hopper car at about the level of the dry material. When air and water are pumped into the bottom of the hopper car compartment, the pumping action causes the dry material to impact the mesh whereby clumps thereof break up and become wetted. Air passes upwardly through the mesh then but clumps of unwetted powder do not. A central port is provided in the mesh for filling the compartment with dry bulk powder.
Claims6
A method for improved in-car slurrying of dry bulk powder contained in hopper compartments in a hopper car, each compartment having means for admitting air under pressure and water into the compartment at the bottom thereof comprising the steps of:
- providing a porous obstruction across the upper portion of the compartment at about the level of the bulk powder therewithin which will admit the passage of air therethrough but not clumps of unwet powder,
- admitting water and air to the bottom of the bulk to pump said material upwardly against said obstruction.
