ABSTRACT:
Describes a chemical feeder for supplying chemical treating agents, e.g., calcium hypochlorite, to a liquid stream, e.g., an aqueous stream. The chemical feeder includes (a) a housing 11 having a chamber 12 therein for receiving solid chemical material, and a single principal opening 33 in the base 87 of the housing, (b) a valve casing 42 positioned below housing 11 and having a single first opening 36, a single second opening 39, a valve chamber 90 that provides fluid communication between openings 36 and 39, and a valve body 57 that is moveable within valve chamber 90 for selectively regulating the flow of fluid between openings 36 and 39, and (c) a fluid conduit 69 positioned below valve casing 42 and having a fluid inlet 72, a fluid outlet 75 and a feeder opening 84. First opening 36 of valve casing 42 is in fluid communication with opening 33 in base 87 of housing 11, and feeder opening 84 of fluid conduit 69 is in fluid communication with second opening 39 of valve casing 42. Fluid both enters and leaves chamber 12 through principal opening 33 in base 87 of housing 11.
