device for continuously feeding powdery solid into pneumatic conveying line

摘要

A device for continuously feeding a powdery solid out of a storage bin (10) and into a pneumatic conveying line (12, 12') comprises a first and a second intermediate vessel (14 and 16) that are placed adjacent to one another. The first intermediate vessel (14) is provided in the form of a sluice vessel having an upper sluice gate (18) and a lower sluice gate (20). The second intermediate vessel (16) is provided in the form of an injection vessel. A pneumatic intermediate conveyance (50) is placed between the lower sluice gate (20) of the first intermediate vessel (14) and an upper inlet (30) of the second intermediate vessel (16). This intermediate conveyance enables the powdery solid to be conveyed out of the first intermediate vessel (14) and into the second intermediate vessel (16).
