Abstract
Abstract A dispersing method and apparatus for metering the dispersing of dry particulate material into a liquid. The apparatus includes a supply container and a metering and dispersing assembly having a clog-preventer with a hub and a plurality of radially extending arms with a rim. Passages are formed between the arms for the passage of dry material. Any large agglomerates that may be formed from the dry material are supported by these arms above the passages to prevent clogging. A dispensing rod capable of vertical movement is positioned within a bore in the hub, and controls the vertical movement of the downwardly inclined dispersing surface attached to the lower end of the rod. The dispersing surface receives the particulate material from the bottom opening, and carries it substantially laterally from the bottom opening to be dispersed into the liquid. An alternate embodiment includes a liquid level control means to insure a proper liquid level in the dispersing container and a washing means to wet the walls of the container. The method of dispersing the dry particulate material into a liquid includes providing a downwardly inclined surface below a supply container for the dry material, and having a bottom opening, selectively metering the materials through the opening and onto an inclined surface. The material is then permitted to move along the surface to the outside perimeter, and fall into the liquid below in a preselected pattern. Simultaneously the liquid is agitated below the falling material in a similar pattern to mix thoroughly the dry particulate material with the liquid.
