초록 ▼

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.

대표청구항 ▼

Apparatus for dissolving and delivering a solution of a solid chemical material comprising a housing having a base member and upwardly extending side walls, said base member and side walls defining a cavity, a chamber having side walls within the lower portion of said cavity, the bottom of the side walls of said chamber being adjacent to said base member and the side walls of said chamber being spaced from the side walls of the housing, thereby forming an annular cavity grid plate means mounted atop the chamber, said grid being substantially parallel to the base member, means to deliver liquid in which said solid chemical material is soluble to said chamber, and means to remove solution of said chemical material from said annular cavity.
