Device for gassing flotation pulp in pneumatic flotation cells comprises feed pipe of constant cross-section for liquid to be gassed and pneumatic connection with outer air

摘要

A device for gassing liquids and suspensions comprises a feed pipe (1) of constant cross-section for the liquid to be gassed opening out into vertical flat intermediate chamber (3) which forms parallel plates (2); and a pneumatic connection with the outer air formed in the region of the opening of the feed pipe so that openings (7) are provided in the plates through which gassing air is sucked via a connection (8), the air being distributed in fine bubbles of required size. Preferred Features: The feed pipe is locked with the lower edge of the upper plate forming the intermediate chamber. The plates have a circular shape.
