Mixing apparatus

Abstract

Mixing apparatus is described in which a plurality of chemical materials are to be incorporated in a carrier liquid, which may be a solvent, such as water, and which is quantitatively predominant, some of the chemical materials being incompatible if brought together directly, or in a wrong sequence, or which are difficult to combine, the materials being combined in the desired proportions in a cascaded arrangement of liquid filled chambers, the respective materials in the desired proportions preferably being supplied from separate sources of materials by pumps, the delivery of the carrier liquid being to a first mixing chamber to which a first chemical material is supplied, the contents of the first mixing chamber being delivered to a second mixing chamber to which another material is supplied, with provisions to prevent back flow, the fluid from the second mixing chamber being delivered to a third mixing chamber to which another chemical material may be added, with additional mixing chambers and pumps as desired to accommodate additional chemical materials, the pumps preferably being simultaneously driven from a single power source and each delivering a controlled quantity of chemical material, with shut off in the event of exhaustion of one of the materials and with shut off if a predetermined quantity of the mixture is available. The material in each mixing chamber is preferably agitated to enhance the mixing.
