Fluid cleaning device

摘要

An apparatus and process for impinging a fluid upon an object to be treated is described. A generally conical-shaped flow of fluid is directed from the cleaning device onto a surface. The fluid contacts the surface and then is reflected through an opening defined by the device and against a deflection plate. The deflection plate has a shape configured to direct the fluid into a fluid return and back onto the surface to be treated.

1. An apparatus for dispensing a fluid from a pressurized fluid source for cleaning a desired surface comprising:
a tubular body defining an opening therethrough, the tubular body including a first fluid passageway and having a first side and a second and opposite side; a plurality of fluid orifices positioned adjacent the opening in an array which is substantially symmetrical about an axis passing through the center of and perpendicular to the opening, the orifices being located on the first side of the tubular body and being in fluid communication with the first fluid passageway, the fluid orifices being angularly arranged such that fluid passing through the orifices forms a substantially symmetrical pattern in a first direction; a deflection plate positioned over the tubular body adjacent to the second side opposite the fluid orifices; a fluid return in communication with the deflection plate; a fluid inlet in communication with the fluid passageway contained in the tubular body, and wherein, fluid entering the inlet flows into the first fluid passageway and is emitted out the fluid orifices under pressure and then directly onto a surface external to the device, upon striking the surface external to the device, some of a fluid is reflected off a surface external to device and through the opening, against the deflection plate, and then a fluid flows out the fluid return and back on to a surface external to the device; wherein a path of a fluid through the fluid inlet and through the fluid passageway to the fluid orifices on the first side and out the fluid orifices cannot include the deflection plate or the fluid return; and wherein the deflection plate comprises a plate covering the opening and substantially encircles the tubular body and is positioned opposite the opening and spaced a distance from the second side of the tubular body.
