Abstract
Described is a chemical feeder comprising a housing having a base and upwardly extending side walls that define a cavity for containing solid chemical material, e.g., calcium hypochlorite. A hollow coaxial chamber is located within the cavity and is seated on the base. The side walls of the chamber are spaced from the side walls of the housing, thereby to define an annular collection zone. A grid having a plurality of perforations covers the hollow coaxial chamber and has a flange associated with the edge of the grid, the perimeter of the flange being adjacent to, or close to but spaced from, the walls of the housing, thereby to permit liquid communication between the portion of the housing cavity above the grid with the collection zone. An inlet conduit is used to supply dissolving liquid to the hollow chamber. An outlet conduit from the annular collection zone to outside the housing wall removes liquid solution of solid chemical material from the collection zone. A valve connected to the inlet conduit controls the flow rate of dissolving liquid to the hollow chamber.
