Abstract
Described herein are articles, assemblies, and methods that use a dust extraction device having a body with a chamber, a first inlet communicating with the chamber extending along a first inlet axis and adapted for releasable connection to a source of pressurized gas, a second inlet communicating with the chamber extending along a second inlet axis and adapted for releasable connection to a dust source, and an outlet extending along an outlet axis and communicating with the chamber. The outlet is adapted for releasable connection to a receptacle, with the outlet comprising at least one baffle that diverts flow of the gas within the outlet.
Claims15
A dust extraction device comprising:
- a body having a chamber;
- a first inlet communicating with the chamber extending along a first inlet axis and adapted for releasable connection to a source of pressurized gas;
- a second inlet communicating with the chamber extending along a second inlet axis and adapted for releasable connection to a dust source;
- and
- an outlet extending along an outlet axis and communicating with the chamber, the outlet adapted for releasable connection to a receptacle, wherein the outlet comprises at least one baffle that diverts flow of the gas within the outlet to create an air vortex within the outlet that results in a change from laminar flow to transient flow.
A method of reducing airborne dust when operating an abrading device using a dust extraction device, the method comprising:
- providing the dust extraction device comprising:
- a body having a chamber;
- a first inlet communicating with the chamber extending along a first inlet axis and adapted for releasable connection to a source of pressurized gas;
- a second inlet communicating with the chamber extending along a second inlet axis and adapted for releasable connection to a dust source;
- and
- an outlet extending along an outlet axis and communicating with the chamber, the outlet adapted for releasable connection to a receptacle, wherein the outlet comprises at least one baffle that diverts flow of the gas within the outlet to create an air vortex within the outlet that results in a change from laminar flow to transient flow;
- connecting the first inlet to the source of pressurized gas;
- connecting the second inlet to the abrading device;
- connecting the receptacle to the outlet;
- and
- flowing the gas through the chamber to induce a Venturi effect whereby dust is evacuated from the abrading device to the receptacle.
