Title:
MIXING BLOCK FOR MIXING MULTI-COMPONENT REACTIVE MATERIAL COATING SYSTEMS AND AN APPARATUS USING SAME
Document Type and Number:
WIPO Patent Application WO1999036238
Kind Code:
A9
Abstract:
The present invention provides a mixing block for mixing fluid components of a multi-component system and which includes at least two component inlets (202, 204), wherein each component inlet receives a respective component or components of the multi-component system; and a solvent inlet (210), wherein the solvent inlet receives solvent for use in cleaning the mixing block. The mixing block further includes at least two flow channels (212, 214), which intersect, wherein an upstream end (216, 218) of each of the intersecting flow channels (212, 214) is connected to at least one of the component inlets (202, 204) and a downstream end of each of the intersecting flow channels is connected to a mixed material reservoir (224), wherein the mixed material reservoir (224) is further connected to and supplies mixed material to an outlet (206). The mixing block also includes a solvent chamber (232) which is connected to both the solvent inlet (210) and the upstream ends of the intersecting flow channels (219, 214) and a solvent diverter (230) which diverts solvent back into the component inlets (230) to facilitate cleaning of the component inlets (202, 204) as well as the intersecting flow channels (212, 214), mixed material reservoir (224) and outlet (226). Additionally, an apparatus which utilizes the above described mixing block is also disclosed.
