Abstract: An electrostatic spray dryer for drying liquid into powder including an elongated cylindrical drying chamber having an electrostatic spray nozzle at an upper end and a powder collection vessel at a lower end. The powder collection vessel includes a removable and replaceable filter collections sock made of filter material for receiving and collecting dried powder from the drying chamber. For cleaning residual powder from an inside wall of the drying chamber, a scraper member is provided that is coupled by magnetic attraction to a manually removable driver on the external surface of the wall.

Abstract: A liquid slurry spraying system for spraying highly viscous slurries, including those with solids content, while maintaining the slurry in agitated condition for optimum discharge. The spraying system includes a nozzle body with a liquid flow passage having a liquid slurry inlet adjacent an upstream end and a spray tip at a downstream end, a valve needle supported in the liquid flow passage for reciprocating movement between spray tip closing and opening positions, and a bladed rotor having a plurality of vanes rotatably supported on the valve needle for rotation as an incident to the direction of liquid slurry from said liquid inlet when the valve needle is in an open position for agitating the liquid slurry for direction to the spray tip.

Abstract: A liquid spraying system having an electrically operated pulse width modulation control for directing a modulated liquid discharge based upon frequency and duty cycle of a reciprocally operated liquid control valve. The spray nozzle assembly includes a nozzle body having an inwardly converging conical chamber communicating between an upstream liquid directing plate and a downstream liquid discharge passage. The liquid directing plate is formed with a one or more rings of circumferentially spaced liquid directing passages angularly oriented with respect to a central liquid flow axis of the nozzle body for directing liquid discharging from said nozzle body discharge passage into a predetermined conical spray pattern.

Abstract: A system for cleaning filter cartridges having a cylindrically configured filter media. The cleaning system includes a tank for containing a cleaning liquid, and an open-sided cage for removably receiving and containing one of the filter cartridges to be cleaned. The cage is supported on a drive shaft of a motorized drive that is positionable for disposing the open-sided cage and filter cartridge contained therein in cleaning liquid in the tank and is selectively operable for rotating the open-sided cage and filter cartridge contained therein during a cleaning cycle for cleaning the filter media of the contained filter cartridge.

Abstract: An electrostatic sprayer operable at high flow rates and low pressures particularly suitable for spray drying. The sprayer includes an elongated body having a downstream spray nozzle assembly through which electrically charged liquid is directed via a central feed tube within the nozzle body and atomizing air is supplied via an annular passage about the liquid feed tube. In one embodiment, the nozzle assembly is an external mix cluster head spray nozzle assembly having a plurality of circumferentially spaced metallic spray tips. In another embodiment, the spray nozzle is an internal mix nozzle assembly having a spray tip with an internal mixing chamber for atomizing liquid prior to discharge.

Abstract: A shower header spray device including an elongated spray header supporting a plurality of laterally spaced liquid spray nozzles each having a central dome formed with an elongated discharge orifice. The spray nozzles each are mounted in a respective pocket of the header, and an elongated rotatable cleaning brush assembly is provided for cleaning the discharge orifices of the spray nozzles. The spray nozzles each have an integrally formed externally threaded mounting ring which captively carries an annular sealing member, and the spray header pockets each are internally threaded for receiving respective spray nozzle screwed into the pocket with the annular sealing member interposed therebetween. The spray nozzles each have a pair of indicator notches to facilitate alignment of the elongated discharge orifices of the spray nozzles in common relation to a longitudinal axis of the spray header.
