Abstract
A device for transferring pulverulent material, for example, powdery material, including an enclosure (3) wherein the pulverulent material to be transferred is stirred and pressurized; a first pipe (8) and a second pipe (9) which transport the material towards its destination; and a gas intake (14, 15) for introducing gas to the second pipe (9). In one aspect of the invention, pipe (8) forms a nozzle (12), oriented in the direction of the material flow and directed toward second pipe (9). The gas intake (14, 15) may emerge at the lower end of the first pipe (8), outside the nozzle (12), wherein the gas is introduced into the second pipe (9) through a plurality of through orifices (20) oriented substantially parallel to the flow direction of the pulverulent material.
Claims20
A device for transferring a pulverulent material, comprising:
- an enclosure having a lower end connected to a first pipe which conveys said material toward the material's place of destination;
- and
- a gas inlet for introducing a gas, at a level, to progress the material toward said place of destination;
- characterized in that at the level of the gas inlet, said first pipe forms a nozzle, pointing in the direction of the flow of the material, said nozzle emerging into a second pipe, of substantially the same diameter as the first pipe, wherein the gas inlet emerges adjacent the lower end of the first pipe, outside the nozzle, said gas being introduced into the second pipe by a plurality of through-orifices, the through-orifices positioned substantially in the same plane as the lower end of the nozzle and oriented substantially parallel to the direction of flow of the pulverulent material.
A device for feeding a powder to a bath of molten metal, comprising:
- an enclosure having a lower end connected to a first pipe which conveys the powder toward the bath of molten metal;
- an inert gas inlet for introducing a gas, at a level, to progress the powder toward said bath;
- characterized in that at the level of the inert gas inlet, said first pipe forms a nozzle pointing in the direction of the flow of the powder, said nozzle emerging into a second pipe, of substantially the same diameter as the first pipe, wherein the inert gas inlet emerges at the lower end of the first pipe outside the nozzle, said gas being introduced into the second pipe (9) by a plurality of through-orifices, the through-orifices positioned substantially in the same plane as the lower end of the nozzle and oriented substantially parallel to the direction of flow of the powder.
