Title: The Innovative Contributions of Daniel Belmain
Introduction
Daniel Belmain is a notable inventor based in Uriage, France. He has made significant contributions to the field of electrostatic spraying technology. With a total of 2 patents to his name, his work focuses on enhancing the efficiency and effectiveness of coating products.
Latest Patents
Belmain's latest patents include a triboelectric projector and an electrostatic sprayer device for spraying products in powder form. The triboelectric projector is designed for pulverulent coating products and features a channel for charging the coating product. It includes a supply conduit that connects to a source of coating product, allowing a mixture of air and coating product to circulate. The invention also incorporates an air injector for dilution and acceleration of the mixture. The process for controlling this projector involves measuring the charge in the charging channel to servo-control the instantaneous flow rate of air injected.
The electrostatic sprayer device comprises an air-powder mixture pipe with an ejector orifice. It features a charging electrode adjacent to the orifice and a counter-electrode that is coaxial and positioned to the rear of the charging electrode. This design creates an annular space between the two electrodes, allowing for the generation of an electric field that attracts free ions towards the counter-electrode. A blower adjacent to the counter-electrode discharges into this annular space, enhancing the spraying process.
