Abstract
An enclosure designed to maintain the purity and physical characteristics of a slurry within a preferred range during the manufacture of shell molds is disclosed. The tank is in the form of a trough with flat side walls and a curved member forming the front, bottom and back of the trough. The entire trough is water cooled and a cover along the top completes the enclosure. The enclosure is fitted with means for circulating the slurry and a liner having an airfoil member. Various sensing and control means are interconnected through a feedback system which continuously monitors and controls the conditions of the slurry.
Claims11
A tank assembly for maintaining a slurry used in the formation of a shell mold over a pattern comprising:
- a tank;
- a removable, resilient liner which conforms to the general internal contour of the tank and fits into the tank;
- pump means which extend into the tank for circulating slurry contained by the liner;
- and
- said liner including a wing type airfoil member extending across the liner, at an intermediate vertical position thereof and spaced from the bottom, whereby to enhance said circulation.
