Latest Patents

One of Correard's latest patents is an electrostatic sprayer device designed for spraying products in powder form. This device features an air-powder mixture pipe with an ejector orifice at one end. It includes a charging electrode adjacent to the orifice and a counter-electrode that is coaxial with and positioned behind the charging electrode. The 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 positioned near the counter-electrode discharges into this annular space, enhancing the efficiency of the spraying process.

Another significant patent by Correard is a method and device for recovering powder, particularly useful in powder-coating installations. This method utilizes processing plants that operate at pressures different from atmospheric pressure. The system fluidizes powder accumulating in a receptacle, creating a pressure head to compensate for the pressure difference. The corresponding device includes a vertical column that connects the receptacle with the processing plant, ensuring effective powder recovery.
