Definitions

  • the present invention relates to fluidization equipment for a container for powdered products, more particularly intended, for example, for bulk transport wagons of cement or powdered mineral matter.
  • the present invention allows, while using simple usual porous fabrics of low cost price, to produce a simple fluidization equipment, at low manufacturing cost, and making it possible to reduce the downtime of wagons or containers by reducing times disassembly, reassembly and tensioning of the fabrics during maintenance operations.
  • the invention applies to fluidization equipment for a container for pulverulent products, consisting of boxes fixed to the internal wall of the container and comprising a perforated sheet metal part supporting an air-permeable element, in which the boxes are supplied with compressed or pressurized air which passes through the element to fluidize the products in the vicinity of the boxes and facilitate their flow towards a drain orifice, and in which each interval between two consecutive boxes comprises a fixed connecting piece, with means for fixing at the same time the edges of two elements on their respective boxes by clamping a pinch piece.
  • the permeable element being a canvas
  • the connecting piece forms with each adjacent box an angle open towards the interior of the container
  • the nipping piece has on each side a conjugate projecting shape determined so as to generate a pull on each edge of the fabric during its tightening and pinching between the box and the connecting piece.
  • the side walls facing the neighboring box are also made of perforated sheet metal, and the connecting pieces are welded to the side walls of the boxes, above the welding thereof on the wall of the container, so as to constitute, between two consecutive boxes, a chamber closed towards the inside of the container and open on each of the two boxes by the orifices of the sheet.
  • Figure 1 is a partial perspective view in cross section of the wall of a tank for powdery products, and shows the structure of the caissons and fluidization before setting up the porous fabrics.
  • Figure 2 is a section on a larger scale of the area between two consecutive boxes.
  • each box 2 is constituted by a perforated sheet folded or stamped in the shape of a trough with slightly flared edges. They are welded in 3 by their edges on the bottom of the tank. Although this is not visible in the partial drawings, the boxes are obviously closed at their ends, either because they come into abutment on an internal partition of the tank, or by a solid sheet at the end.
  • the flared edges of the caissons are joined by a full sheet 5 folded in an inverted U and welded in 6 by wings on the perforated edges of the boxes.
  • the welds 6 for attaching the part 5 to the boxes 2 are sufficiently distant from the wall 1 so that there remains at least one perforation line below the sheet metal of the boxes.
  • the part 5 thus delimits a chamber 7 between two caissons, a chamber which is closed towards the inside of the tank, but which communicates freely with each of the two caissons by means of the perforations closest to the wall 1.
  • the sheet 5 is pierced with orifices 9, with a nut 10 welded underneath on the axis of each orifice.
  • the perforated sheet of the boxes 2 is covered with a porous fabric 12 (FIG. 2), the lateral edge of which extends beyond the box as far as the connecting piece 5.
  • a pinching piece 13, constituted by a flat iron with folded edges is fixed on the piece 5 by means of a series of countersunk head screws 14 engaged in the orifices 9 and the nuts 10.
  • the fabric 12 is pinched both by its end between the two flat parts of the parts 13 and 5, and at the same time by the wings of the iron 13 in the V-shaped groove formed between the flared edges of the box and the edges of the connecting piece 5. It follows that during the tightening of the screws 14 the fabrics 12 undergo a traction which makes it possible to keep them properly stretched on the perforated sheets of the boxes.
