Abstract:
A receiver for a pneumatic conveyor for receiving and discharging particulate matter, comprising:an upstanding receptacle having an inlet port and a gravity feed discharge opening; a flow control valve at the discharge opening controlling discharge flow of particulate matter from the upstanding receptacle, the flow control valve including a valve seat circumscribing the discharge opening and a tapered plug selectively engageable with the valve seat to selectively occlude the discharge opening; wherein the plug is mounted to the upstanding receptacle to permit reciprocal motion of the plug into and out of the receptacle and substantially parallel to the discharge flow of particulate matter, between a first position in which the plug engages the valve seat, occluding the discharge opening, and a second position in which the plug is displaced from the valve seat; and an actuator connected to and disposed substantially externally of and above the upstanding receptacle and connected to the plug such that actuation of the actuator moves the plug between the first and second positions.
