PNEUMATIC DISCHARGE ARRANGEMENT

摘要

A discharge arrangement comprises a hopper having sloping sidewalls provided with a discharge opening communicating with a tube adapted to be connected to a pneumatic conveying system. The discharge opening is provided with a valve member which cooperates with a movable valve element to regulate the discharge of material. The valve is movable horizontally and includes opposed cutting edges which cooperate with the valve element in cutting through the material during closing of the valve. The valve element is movable upwardly free of the valve so that all the edges of the valve and valve element are free and clear and can be cleaned during a cleanout operation.
