Abstract

L'installation comporte un silo de stockage (10), un silo de distribution (30), une série de doseurs (24A et 38) pour extraire les matières pulvérulentes du silo de distribution (30), des conduites de transport pneumatique (36) reliant chacun des doseurs à ladite enceinte, ainsi que des moyens pour transférer automatiquement la matière pulvérulente du silo de stockage (10) vers le silo de distribution (30). The installation includes a storage silo (10), a distribution silo (30), a series of dosers (24A and 38) to extract the pulverulent materials from the distribution silo (30), transport lines tire (36) connecting each of the dosers to said pregnant, as well as means to transfer the powder material of the silo storage (10) to the distribution silo (30).

Pour réduire la taille des silos et des conduites, on a prévu deux silos intermédiaires (24A, 24B) reliés chacun à travers des vannes automatiques (22, 28), en amont, au silo de stockage (10) et, en aval, au silo de distribution (30) et un circuit de pressuri­ sation reliant une source de gaz inerte sous pression à travers des vannes automatiques (50A, 50B) à chacun des silos intermédiaires (24A, 24B). To reduce the size of silos and pipes, two intermediate silos (24A, 24B) have been provided each through automatic valves (22, 28), upstream at the storage silo (10) and downstream at the distribution silo (30) and a pressurized circuit station connecting a pressurized inert gas source through automatic valves (50A, 50B) to each intermediate silos (24A, 24B).
