Abstract
Devices for the pneumatic conveying of particulate and powdery bulk goods to obtain high conveying speeds with low energy expenditure. The devices have a fluidized conveying pipe with fluidizing elements, in which pipe the fabric layers of the fluidizing elements are formed from two or a plurality of sintered and rolled metal wire fabric layers whose wires, at least those of the top outer layer, are tilted or bent downwards to form aligned flow channels inclined in the direction of conveying.
Claims20
A device for the pneumatic conveying of particulate and powdery bulk goods in the horizontal, rising and/or falling direction, comprising:
- a. a conveying pipe,
- b. a fluid gas source which is connected to the conveying pipe via pipelines,
- c1. fluid gas feed devices on a front side of the conveying pipe for feeding fluid gas in the direction of conveying,
- c2. fluid gas feed devices on a bottom of the conveying pipe,
- d. fluidizing elements in the conveying pipe in the form of fabric layers through which fluid gas flows from the bottom of the conveying pipe,
- e. bulk goods feed devices having a supply pipe which opens in an upper side of the conveying pipe;
- wherein
- the fabric layers of the fluidizing elements are formed from two or more sintered and rolled metal wire fabric layers whose wires, at least those of the top outer layer, are tilted or bent downwards to form aligned flow channels inclined in the direction of conveying.
