Abstract
A system utilizing a rotary atomizer for applying a liquid based substance to particles. In one example, a motor provides an in-line, direct drive force on a cage atomizer. With some systems, the cage atomizer has a vertical axis of rotation. With some systems, the motor is mounted external to the particle path and supported by a housing structure that provides an angled particle path. With some systems, other types of rotary atomizers may be used such as disk, bowl, or hollow disk rotary atomizers. With some examples of cage atomizers, a first portion of the cage atomizer may include a thread set that screws to a thread set of a second portion to hold a perforated structure in place. With some systems, the thread sets surround the axis of rotation.
Claims18
A cage atomizer apparatus having an axis of rotation comprising:
- a first, upper support structure having an upright hollow tubular body presenting a liquid based substance inlet and a depending sidewall, said sidewall having at least one aperture therethrough for passage of said liquid through the aperture;
- a second support structure disposed below said first structure;
- a perforated structure located between the first and second support structures, the rotation of the atomizer providing centrifugal force on said liquid based substance passing through said aperture and then through the perforated structure;
- a first set of threads surrounding the axis of rotation and fixably coupled to the first support structure;
- a second set of threads surrounding the axis of rotation and fixably coupled to the second support structure;
- wherein the first and second support structures are coupled at least via an engagement of the first and second sets of threads.
A rotatable cage atomizer comprising upper and lower spaced apart structures, an elongated central shall assembly defining the axis of rotation of the cage atomizer extending between and interconnecting the first and second structures, said shaft assembly comprising a hollow tubular body secured to said upper support structure and presenting a liquid based substance inlet and a depending sidewall, said sidewall having at least one aperture therethrough for passage of liquid through the aperture, and a perforated structure surrounding the shaft assembly between the upper and lower structures, said shaft assembly having threading surrounding said axis of rotation permitting disassembly of the atomizer.
