Abstract

1. Fluidisation equipment for a pulverulent products container, consisting of boxes fixed by the inner wall (1) of the container and comprising a part (2) made of perforated metal plate, supporting an element (12) permeable to air, in which the boxes are fed with compressed or high-pressure air, which passes through the element (12) to fluidise the products in the region of the boxes and to facilitate their flow towards a discharge orifice, and in which each gap between two consecutive boxes includes a fixed connecting piece (5) with means for simultaneously fixing the edges of two elements (12) to their respective boxes by tightening a gripping piece (13), characterised in that, the permeable element (12) being a gauze, the connecting piece (5) forms, with each adjacent box, an angle opening towards the interior of the container, and in that the gripping piece (13) has a conjugated projecting shape on each side, determined so as to generate a tractive force on each edge of the gauze (12) during its tightening and gripping between the box and the connecting piece (5).
