Abstract

A liquid process tank that provides a quick dump feature includes a fixed bottom wall assembly and moveable tank side walls that contain liquid and also act as a quick dump valve for the liquid. The bottom wall assembly includes an acoustic transducer secured thereto. The tank side walls are secured to a plurality of linear actuators adapted for vertical movement. A seal is secured to the lower edge of the side wall assembly to impinge on a land surface that extends about the perimeter of the bottom wall assembly. The linear actuators are retracted to draw join the bottom and side wall assemblies to retain liquid, or activated in unison to drive the tank walls upwardly from the fixed bottom wall assembly, creating a bottom opening in the tank that quickly discharges all the liquid from the tank.
