Storage apparatus includes a supporting base () supporting silos () having a lower conical portion () and silo port () controlled by an outlet knifegate valve (), and a charging port () controlled by an inlet knifegate valve (). An upper portion () of the silo is closed by a domed top (). The silo ports () are manifolded to a common outlet (not shown). A charge manifold () interconnects the respective upper charging ports () and connects the ports to the cuttings source conduit (). A pressure/vacuum port () is connected via cycle control valve () to an ejector assembly (not shown) valved to be able to cycle between a vacuum phase and a pressure phase of aboutpsig using a compressed air source. Control means is selectively operable to control the outlet valve (), inlet valve () and cycle control valve ().

Storage apparatus

A pneumatic evacuation pump includes an inlet assembly having an inlet valve, a charging port, and purge air injection means. A chamber includes a charge end opening to the charging port, and a discharge end. A delivery assembly includes a passage between the discharge end and a delivery outlet, a delivery valve interposed in the passage between the discharge end and the delivery outlet, and a venturi vacuum source opening to the passage between a discharge valve and the discharge end. Exhaust air injection means located downstream of the discharge valve utilizes exhaust air from the venturi vacuum source. A compressed air supply supplies the venturi vacuum source and the purge air injection means. Control means acts to coordinate a cycle of operation of the venturi vacuum source, the purge air injection means, the exhaust air injection means and the inlet and delivery valves.

Pneumatic evacuation pump

A Pump consisting of a pressure vessel (), an inlet nozzle (), an ejector nozzle () by which vacuum and pressure are applied, and an outlet nozzle (). The inlet and outlet nozzles () are selectively closed by interconnected knife gate valves, operated in tandem by a pneumatic cylinder whereby when one valve is closed, the other is open an vice-versa. An ejector valve located in the ejector nozzle () alternately creates vacuum and generate air flow through the vessel (). The air from the ejector is introduced into the discharge line after closure of the outlet valve.

Pump apparatus

Vessels (and) are associated with an inlet manifold () passing to inlets (), each controlled by a knifegate valve (). The lower ends of the pots () and (), and pots () and (), pass material through respective outlet knifegate valves () to respective first () and second () delivery lines. The respective knifegate valves () and outlet knifegate valves () of pots () and () on the one hand and pots () and () on the other, are operable by respective common pneumatic actuators (). Each pot has an ejector assembly () having an upper chamber (), an air injector nozzle (), and an accelerator tube () to create the venturi function. An air cycling valve () transitions the upper chamber () between a depressurized space and a pressurized space. The accelerator tube () exhausts to a delivery line (or). Ejector assembly () air is supplied via air control valve (). The respective delivery lines () and () each have an eductor port () which allow for air to be ported into the line. The completed load and discharge cycle is governed by a pneumatic PLC and pneumatic timers.
