Abstract

Fremgangsmåte for tømming av en beholder med tørt pulver gjennom et utløp l eller nær beholderens bunn hvor drivgass ledes inn gjennom en innløp ved eller i beholderens bunn for å fluldisere og bygge opp drlv- gasstrykk l beholderen, hvor strømmen av drivgass kobles om fra å strømme gjennom Innløp l eller ved beholderens bunn til å strømme Inn gjennom et innløp i eller nær beholderens topp når drlvgasstrykket l beholderen kommer over et på forhånd definert nivå. Det blir dessuten beskrevet en vekselventil for automatisk omkobling av en Inngående gasstrøm som kommer Inn gjennom Innløp (2), mellom to utløp (3, 11), hvor vekselventllen er anordnet til l normalstllllng å lede gasstrømmen til primært utløp (3)og for automatisk å stilles om til å lede gasstrømmen ut gjennom sekundært utløp (11) når gasstrykket mot sekundært utløp (11) kommer over et visst nivå.Method for emptying a dry powder container through an outlet 1 or near the bottom of the container where propellant is fed through an inlet at or into the bottom of the container to fumble and build up the fuel gas pressure in the container, where the flow of propellant is switched from flowing through Inlet 1 or at the bottom of the container to flow In through an inlet at or near the top of the container when the fuel gas pressure in the container exceeds a predefined level. In addition, an alternating valve is described for automatic switching of an Incoming gas flow entering through Inlet (2), between two outlets (3, 11), the alternating valve being arranged for normal operation to direct the gas flow to primary outlet (3) and for automatic to be adjusted to direct the gas flow out through the secondary outlet (11) when the gas pressure towards the secondary outlet (11) exceeds a certain level.
