Abstract
A particle collector for intercepting and collecting small particles dislodged during grinding operations utilizes a vacuum unit to trap particles within a collection bag. Uniquely formed intake nozzles provide effective particle pickup for both bench-type and hand-held grinding units. The nozzles may be interchanged without requiring the use of tools, and the collector may thus be conveniently switched from a bench-type grinder to a hand-held grinder. The vacuum source is portable and housed in a cabinet uniquely designed for quiet operation and even airflow. Particles are collected in a reusable bag and may be processed to recover precious substances. The nozzle designed for use with bench-type grinders may be horizontally or vertically positioned, as required by work space limitations.
Claims6
In an apparatus for intercepting and collecting particles debrided during use of a hand-held grinder, said apparatus of the type having a vacuum line communicating at one end with a source of vacuum within a cabinet and, at the other end;
- with a collector, said grinder of the type having a grinding wheel rotating about an axis, the improvement comprising:
- a hood formed on said collector,
- an exit port formed on said hood at right angles to said axis of rotation of said grinding wheel,
- said exit port being substantially larger in diameter than the thickness of said grinding wheel,
- said hood shaped to position said port proximate said grinding wheel,
- said vacuum line attachable to said hood at said exit port, whereby particles intercepted by said collector are drawn therethrough to said cabinet;
- a body integral with said hood;
- and
- means to removably attach said body to said grinder.
In an apparatus for intercepting and collecting particles debrided during use of a hand-held grinder, and bench type grinders, said apparatus of the type having a vacuum line communicating at one end with a source of vacuum within a cabinet, and at the other end with a collector, said grinder of the type having a grinding wheel rotating about an axis, the improvement comprising:
- said collector being free-standing and having a front face and a rear wall,
- a passage communicating through said collector from said front face through said rear wall,
- a first portion of said passage being defined by upper, lower and lateral inner wall segments,
- said inner wall segments tapering from said front face toward said rear wall to define said cavity as pyramidal, with the apex of said pyramidal cavity extending toward said rear wall,
- a second portion of said passage defined by segments of said rear wall forming a cylindrical duct extending from said apex through said rear wall;
- said cylindrical duct attachable to said vacuum line whereby a partial vacuum may be created within said cavity,
- said collector being freely positionable proximate said grinding elements to intercept particles debrided by said hand-held grinders or said bench type grinders whereby particles intercepted by said collector are drawn through said passage to said vacuum line and thereby to said cabinet.
