Abstract (en)
[origin: US2007056887A1] A device for blowing against individual pieces of a material flow conveyed via a freefall path or a link conveyor using a gaseous or liquid medium, comprising at least one connection opening ( 9 ) for the gaseous or liquid medium, as well as multiple blowing nozzles ( 16 ), via which the gaseous or liquid medium is blown in a controlled way on predetermined individual pieces of the material flow, as well as valves, preferably solenoid valves, assigned to the blowing nozzles ( 16 ), through which the blowing procedure is triggered and stopped, a flow channel being provided between each blowing nozzle ( 16 ) and the valve seat ( 19 ) of the valve assigned to a blowing nozzle ( 16 ), which only causes a single deflection of the gaseous or liquid medium. In order to allow optimum positioning of the valves and keep the pressure loss low, the valve plunger ( 5 ) of the valve is situated essentially perpendicularly to the blowing nozzle ( 16 ) or encloses an acute angle alpha with the axis of the blowing nozzle ( 16 ).
