Abstract
The apparatus of the present invention includes a mixing tube and inlets for conveying substances into the mixing tube such that the components intersect at a common point. A replaceable insert directs a dry component into the mixing tube. A liquid inlet bi-directionally sprays a liquid component between a wall of the mixing tube and the insert and toward the common point. A recirculation inlet directs a recirculated component toward the common point. Mixing is enhanced by a flow deflector and a flow interceptor which converge and turn the substances. The method of the present invention includes conveying substances into a mixing tube and intersecting the substances at a common point in the mixing tube to form a mixture.
Claims38
A mixing apparatus, comprising:
- a mixing tube having an attached collar;
- first means for conveying a dry substance into said mixing tube wherein said first means includes a replaceable insert constructed of an ultra high molecular weight polyethylene;
- said insert is received through an opening of said collar until a flange of said insert engages an annular shoulder of said collar,
- second means for conveying a liquid substance into said mixing tube;
- third means for conveying a recirculated mixture of said dry and liquid substances into said mixing tube;
- and
- wherein said dry substance, said liquid substance and said recirculated mixture are delivered to a common point of intersection within said mixing tube such that a mixture is formed.
