ABSTRACT:
An intermittently operating pneumatic plug-conveyor has a pipe-shaped suction head for fluid material, which passes therethrough in a column, which resists dispersion. The conveyor is provided with an adjustable slot, a manifold in alignment with the slot, gas connection supports, and a timer-controlled valve system of such proportions, that the resistance of the column of the material located in the suction head relative to atmospheric pressure, is greater than the combined air-resistance of the gas supports with the adjustable slot and the valve; gas nozzles from pressurized gas supply controlled by a magnetic valve with a timer are arranged below the manifold and a back-up flow protection is provided at the receiving input.
