SYSTEM FOR DISTRIBUTING A FLUID SUBSTANCE

摘要

A system (100) for distibuting wax or a similar substance in semi-solid form is provided which includes a liquid wax supply system (500), a wax conditioning system (200) including a heat exchanger (210) which cools the wax to a semi-solid state and an accumulator (212) for storing conditioned wax until needed, and a die press or similar work station (400) which receives semi-solid wax from the accumulator in a continuous stream or flow. Such a system (100) allows a lost wax die press (400) to operate without need to manually open and reload the press with wax. An automated control system (800) according to the invention allows die press reloading to occur automatically when needed, and operates the wax conditioning system (200) as needed to maintain a supply of wax in the accumulator (212). Wax tunnelling problems are avoided by means of a piston (314) disposed in the heat exchanger (210) which is movably interposed between hot liquid wax entering the heat exchanger (210) and cooler, semi-solid wax leaving the heat exchanger (210).
