Abstract

New venturimºtrico device for transport of particulate material by a pneumatic conduction, whose contribution takes place as a result of the aspiration caused by the depression produced by said device, which is inserted at a certain point, between the primary, pneumatic line, and the line transport, essentially characterized by comprising a derivation of the fluid under pressure or bridging from the primary conduction to the enclosure affected by the venturi phenomenon, advantageously defined between the injector, from the tubular section of greater width anterior to that configured according to the narrowing maximum of the venturi arrangement and the annular enclosure that coaxially surrounds the extreme throat of said venturimetric tubulant, or threshold of maximum depression of the pneumatic arrangement, whose zone is immediately before the absorption cavity of the material, which is led to said point through a duct that impacts orthogonally to said cavity, connected to a reserve tank, having said derivative conduit interposed, a flow compensator between the primary and the secondary, all with the purpose of modifying at will the magnitude of said depression, essentially in its height terms piezomºtrica and kinetic, and therefore able to alter the amount of material aspirated, ie to control the quantitative proportion of material added in relation to the volume unit of conveyor fluid, according to a very regular progressive dosage and without change of the volume of transporter fluid to each work pressure.
