Title: Innovations of Francois Julien Saint Amand
Introduction
Francois Julien Saint Amand is a notable inventor based in Le Touvet, France. He has made significant contributions to the field of particle separation technology, holding 2 patents that showcase his innovative approach to solving complex engineering challenges.
Latest Patents
His latest patents include a device for selectively separating particles in a liquid. This invention outlines a process and device for separating particles from a suspension. The process involves introducing the suspension into a rotating separation chamber, where the flow is regulated to maintain an angular velocity slightly higher than that of the chamber's wall. The design allows for the removal of the bulk of the treated suspension from a peripheral area of the chamber. The heavy fraction is extracted from a zone near the sidewall, while the light fraction is taken from a zone closer to the longitudinal axis. An intermediate fraction can also be removed from a separate zone between the light and heavy fraction outlets. The apparatus features a separation chamber with a longitudinal axis, sidewalls, and inlets for introducing suspension and auxiliary fluid. Rotating means are employed to direct the suspension and fluid towards the sidewalls, facilitating the collection of effluents from designated areas.
