Abstract:
A hydraulic conveyance system serves to level out a spiked, uneven flow of particulate material to a more even flow condition prior to the particles being delivered to a destination. In one particular application, the hydraulic conveyance system permits ice particles to be delivered from a batch discharge ice machine of a thermal energy production, storage and reclaim system to the thermal energy storage tank of the system at a relatively even rate, without the use of any mechanical delivery mechanisms. The hydraulic conveyance system incorporates a flooded hold-up tank which, in the case of particulate ice conveyance, receives the spiked, batch discharge from the ice machine and discharges the ice therefrom to a selected number of destination points at a more even flow condition. A rotational movement is imparted to the water surface in the flooded hold-up tank, thereby causing the floating ice particles to rotate in the tank in proximity to a boundary wall of the tank. Weirs located in the boundary wall permit the ice and a portion of the water in the tank to overflow therethrough.
