Switch for conveying system for pneumatically conveying pulverulent material, has closure element whose inflatable seal is attached to pressurized air device on bulk material flow sealing side

摘要

The switch (1) has an inlet tube (2) and two outlet tubes (3, 4) arranged in a switch chamber (11). The chamber comprises an adjustment device (6) and a closure element (5) on a side turned away from a bulk material flow sealing side (55) and an opposite connection side (56). The closure element closes and opens entrances of the outlet tubes to the chamber. A pressurized air device (53) and fluidizers (7-9) are arranged along the inlet tube, the outlet tubes and the chamber. An inflatable seal (51) of the closure element is attached to the pressurized air device on the sealing side. The closure element is designed as a slider. An independent claim is also included for a conveying system for pneumatically conveying bulk material.
