Abstract
A chemical loading system includes a venturi located at the top of the solution tank to reduce the fluid mass that has to be lifted into the tank. An anti-bridging nozzle at the outlet of the eductor hopper assures that material is pushed into the vacuum created by the venturi. To reduce air space in the granular material and increase pull by the venturi vacuum, fluid is directed to the material through the anti-bridging nozzle and through a rinse ring around the top of the hopper. The rinse ring, also used to rinse the hopper after loading the material and provide structural rigidity, includes a rolled edge at the top of the hopper walls with notches in the edge of the ring to provide improved placement of rinsing solution.
