Abstract
A bottom for a fluidized bed conveyor is composed of a plurality of members provided with openings and located in contact with each other so that their points of contact are gas impermeable at least during operation of a fluidized bed. The openings may be formed as circumferentially closed holes and/or as laterally open recesses. The members may laterally abut against each other, or may be provided with interengaging lateral projections. The members may be located so that at cold temperatures small intermediate spaces remain therebetween, which spaces are closed during operation as a result of thermal expansion of the members under the action of high working temperatures. Bracing element or elements may be provided which urge the members toward one another.
Claims16
A bottom for a fluidized bed, particularly for a fluidized bed conveyor, comprising a plurality of metal members each provided with a plurality of openings for passing a fluidizing gas therethrough and together forming a substantially elongated shape, said members adjoining each other and contacting with each other at contact points which are gas impermeable at least during operation of the fluidized bed, each of said members being elongated and provided with a lateral projection extending in a direction transverse to the direction of elongation, said projections being in contact with each other and said members being movable relative to one another when said projections are in contact with each other.
A bottom for a fluidized bed, particularly for a fluidized bed conveyor, comprising a plurality of metal members each provided with a plurality of openings for passing a fluidizing gas therethrough and together forming a substantially elongated shape, said members adjoining each other and contacting with each other at contact points which are gas impermeable at least during operation of the fluidized bed, said members being elongated and located adjacent to one another in direction transverse to their direction of elongation and in a common plane, said bottom having two ends spaced from one another in the transverse direction;
- and bracing means arranged at one of said ends and pressing said members toward one another in said transverse direction and in said common plane.
A bottom for a fluidized bed conveyor having a frame, comprising a plurality of metal members each provided with a plurality of openings for passing a fluidizing gas therethrough and together forming a substantially elongated shape, said members adjoining each other and contacting with each other at contact points which are gas impermeable at least during operation of the fluidized bed, said members being elongated and having two end portions spaced from one another in the direction of elongation, each of said end portions having a lower surface arranged to support on the supporting frame and being flat so that said members can move in the direction of elongation with contact of said lower surfaces of their end portions with the supporting frame.
A bottom for a fluidized bed, particularly for a fluidized bed conveyor, comprising a plurality of metal members each provided with a plurality of openings for passing a fluidizing gas therethrough and together forming a substantially elongated shape, said members adjoining each other and contacting with each other at contact points which are gas impermeable at least during operation of the fluidized bed, the openings of said members having differing total cross-sections for passing the fluidized gas therethrough, said members being so located relative to one another that the speed of the fluidizing gas at various locations of the fluidized bed has differing magnitudes, each of said members being characterized by two factors one of which is a predetermined number of said openings and the other of which is a predetermined size of each of said openings, said members differing from each other by at least one of said factors so as to obtain said different flow-speed magnitudes of said fluidizing gas at said various locations.
