Abstract

Apparatus for transporting a finely divided material, in an essentially dry state, including a casing or box provided with means for the admission of a material therein and a material outlet and comprising a section of upper duct and a ventilation chamber below it, a gas permeable floor between the upper duct section and the ventilation chamber, along which the material adapted for transport is found, the floor comprising a plurality of sections and the end of which is upstream of each section of downstream floor at a higher height than the downstream end of the preceding floor section an interior wall extending upward in the upper conduit section at the downstream end of each floor section, a partition adjacent a certain distance upstream of each interior wall and forming said interior wall and the side walls of the enclosure an ascending passage, is Each partition is separated from the floor section permeable to the gases underneath, means for raising a gas through each section of soil in order to fluidify the material that is on it and make it flow at the same time. length of the floor section and below the partition located on the floor section, including each section of floor a smaller area below the passage and a larger area upstream with respect to it, means to produce a flow of gas through of the smaller area of each section of soil greater than the flow rate through the greater area of the stretch of soil, whereby the fluidized material that flows below the partitions to the smaller areas expands and is forced to flow towards up through the passages, at least one part of the walls of each passage ending near the top of the envelope and forming an overflow edge of the material that rises through the passage, while the section of The next immediate floor in the downstream direction has its upstream end located so as to receive the material flowing over the overflow edge, and the overflow edge adjacent to the downstream end of the last floor section, in the direction of downstream it partly defines the exit opening of the material.
