Abstract
The particularity of this invention is that the material is injected in the divergent section of the venturi. The innovative material Conveying Venturi tube consist of two parts: the main tube and the feeding tube injecting the material by gravity, at the end of the cylindrical throat into the diffusion section. The venturi is composed of a contraction section, a throat section, and a diffusion section. This device will convey distances exceeding 120 meters. The present invention permits multiple distances conveying by easily install another Conveying Venturi System at the end of the first conveying tube for extra length of conveying.
Claims8
A long-distance pneumatic conveyor for conveying flake ice having a converging-diverging conduit forming a venturi;
- said venturi comprising a bulk material inlet, a motive air inlet, and an outlet;
- said motive air inlet having a cylindrical first section followed in a conveyance direction by a converging conic section;
- said outlet having a conic section diverging in the conveyance direction followed by cylindrical second section;
- said venturi having a throat between the conic sections;
- said bulk material inlet having a first bulk material cylindrical section leading to a converging polygonal section dropping and aspirating bulk material into a downstream end of the throat along a longitudinal conduit axis.
