Patent

CA 2227227

The disclosure pertains to a device for withdrawing bulk material (96) from a pressurised container (2). The device comprises at least one sluice trap unit (24, 26) with a lower (42, 44) and an upper (40) sluice gate. The sluice trap unit (24, 26) is situated beneath a plate (76, 76') into which it forms a discharge unit (28, 30) for the bulk material (96). The upper sluice gate (40) is provided with a sealing disc (66) arranged above the plate (76, 76') in such a way that it can be positioned above the discharge unit (28, 30) of the sluice trap unit (24, 26) and then, after forming a tight join with the border of the discharge unit (28, 30), forced by excess pressure in the pressurised container (2) against that border.

L'invention concerne un dispositif pour retirer une matière en vrac (96) contenue dans un récipient sous pression (2), ledit dispositif comprenant au moins un réservoir de type écluse (24, 26) comprenant une porte d'écluse inférieure (42, 44) et supérieure (40). Le réservoir (24, 26) est situé sous une plaque (76, 76') dans laquelle il forme une unité de décharge (28, 30) pour la matière en vrac (96). La porte d'écluse supérieure (40) présente un disque étanche (66) placé au-dessus de la plaque (76 76') de sorte qu'il peut être positionné au-dessus de l'unité de décharge (28, 30) du réservoir (24, 26) et, après avoir été raccordé de façon étanche à la bordure de l'unité de décharge (28, 30), peut être comprimé contre cette bordure par une surpression dans le réservoir sous pression (2)
