Method and apparatus for mixing and dispensing material

Abstract

The method may be employed for the mixture of certain types of products which require two or more component chemicals or compounds that must be mixed together immediately prior to use. The method comprises mixing the two compounds in the usual fashion inside of a mixing chamber by continuously supplying each of the compounds to the mixing chamber and then introducing air into the chamber while maintaining the chamber open at one end for the dispensing of the material whereby the air provides agitation for the mixture of the materials and provides a suction forwardly of the mixing chamber to draw the mixed compounds therefrom. The apparatus is in the form of a mixing and dispensing gun which comprises a frame on which there is a previously known arrangement for introducing and supplying two or more chemical components to a mixing chamber thru a mixing block with which is mounted an air control valve system for controlling the entry of the two components. A mixing chamber has an air line connected thereto for the purpose of introducing air laterally or radially into the chamber with respect to the longitudinal centerline so as to mix the mixture therein and to provide a suction or Venturi effect outside the chamber to draw the mixed material therefrom.
