<p>1,082,922. Pneumatic conveyers-emptying hoppers. CLAUDIUS PETERS A.G. March 9, 1965 [March 10, 1964], No. 9907/65. Headings B8A and B8E. An apparatus for loading dust-type or fine granular material from a stationary supply nozzle 3 of a hopper to any one of a plurality of intake nozzles on a tanker or the like, comprises a loading trough 1 with pneumatic conveying troughs 2 formed in the base thereof and inclined down to an outlet 5, the trough 1 being movable via rails 9 and wheels 8 to facilitate connection between the outlet 5 and intake nozzles of the tanker. The top of the trough 1 is sealed from the outside atmosphere by a pair of flexible sealing flaps 6 secured to the longitudinal sides of the trough 1 and resiliently engaging each other so that with movement of the trough 1, the two flaps open to pass around the supply nozzle 3 and close together after passing. Exhaust pipes 4 are provided alongside the nozzle 3. Compressed air is supplied to the troughs 2 via connection 7. In another embodiment the seal at the top of the loading trough is formed by a concertina member. In the embodiment of Fig. 3 (not shown) the seal is formed by overlapping plates bent at their ends to grip each other in their expanded conditions, the end plates being connected to the ends of the trough and to the supply nozzle. In the final embodiment of Fig. 4 (not shown) the supply nozzle is rigid with a plate extending over the whole travelling area of the loading trough, the latter having a pneumatically inflatable member mounted around the upper periphery of the trough and inflated when the pneumatic conveying troughs are operated, to sealingly engage the said plate.</p> |
