Abstract:
A distribution head which conveys air-entrained material received from an upright conveyor tube, for use in a system said distribution head having a flow inlet for receiving the air-entrained material from said conveyor tube, a plurality of angularly spaced apart outlet ports and flow divider means for dividing the incoming flow into generally equal parts and directing the divided portions of the flow outwardly through the respective outlet ports, said distribution head having a central axis with said flow inlet being aligned with and concentric with said central axis and said outlet ports being in said angularly spaced apart relation and extending radially outwardly from said central axis, said flow divider means including a flow divider chamber defined within said distribution head and a flow deflector disposed within said chamber and having flow confining ridges thereon separated by smoothly contoured valleys each associated with a respective one of said outlet ports, said flow deflector having a nose portion centered on said central axis and said flow confining ridges commencing downstream of said nose and curving gradually around from combined axial and radial directions adjacent said nose into generally radial directions while the contoured valleys between said ridges gradually become deeper into said deflector to ultimately meet smoothly with interior surfaces of the outlet ports.
