Abstract
A method and an apparatus for filling a silo (1) with a fluidizable material. The arrangement includes conveying devices (5, 9) for supplying material to an upper area of the silo and a central material distributor (10). The material distributor includes a tank (29) which has an inlet (28) and one or more distributor pipes (26, 26′) for distributing material to one or more feed units (11, 11′)which convey the material down towards the surface of the material in the silo.
Claims19
An apparatus adapted to fill a silo with a fluidizable material, said apparatus comprising:
- means for conveying the material by pneumatic transport to an upper area of the silo;
- an annular central material distributor including a tank having an inlet and at least one outlet;
- at least one feed unit having an inlet for receiving the material from said central material distributor, and an outlet for feeding the material in a downward direction toward the bottom of the silo;
- and
- at least one distributor pipe extending from said tank outlet of said central material distributor and said inlet of said at least one feed unit.
An apparatus adapted to fill a silo with a fluidizable material, said apparatus comprising:
- a conveyor which conveys the material by pneumatic transport to an upper area of the silo;
- a central material distributor disposed in the upper area of the silo, said central material distributor including a tank having an inlet and a plurality of outlets;
- an annular plurality of feed units disposed adjacent an upper interior wall of the silo, wherein each of said feed units has an inlet for receiving the material from said central material distributor, and an outlet for feeding the material in a direction toward the bottom of the silo;
- and
- a plurality of distributor pipes, wherein each of said distributor pipes is connected to one of said tank outlets and to one of said feed unit inlets.
A method for filling a silo with fluidizable material, by pneumatic transport the method comprising:
- conveying the material to a central material distributor disposed in an upper part of the silo, wherein the central material distributor includes an annular tank having an inlet and at least one outlet;
- distributing the material towards an interior wall of the silo, from the central material distributor by means of one or more distributor pipes to one or more feed units wherein each of the feed units has an inlet for receiving the material from the central material distributor and an outlet for feeding the material in a direction toward the bottom of the silo;
- and
- distributing the material from the one or more feed units down towards the surface of the material above a bottom of the silo.
