Definitions

  • My invention relates to dust-collectors, and more particularly to centrifugal dust-collectors, wherein the dust-laden air is caused to rotate or whirl for the purpose of massing the dust, as the result of centrifugal action, in a portion of the machine from which the air eventually escapes.
  • my invention consists in the features of construction and combinations of parts hereinafter claimed; but it may be here pointed out that my invention contemplates the provision, in a centrifugal dust-collector, of means for sharply deflecting portions of the air at the level of said inlet from the circular course.
  • my invention contemplates the provision of valves or passages through the deflecting agencies so arranged that dust carried in the deflected air-body may escape therethrough and so arranging the deflecting agencies relative to the tangential inlet that the incoming air-current serves to induce the passage of dust through said valve-openings and in the peripheral undeflected belt into the.
  • My invention also contemplates the provision of a regulating device to operate in conjunction with the air-escape outlet, as hereinafter described, and other features and combinations, which will hereinafter become apparent.
  • Figure 1 is a vertical section on line 1 1 of Fig. 2.
  • Fig. 2 is a horizontal section on line 2 2 of Fig. 1 looking in the direction of the arrows.
  • Fig. 3 is a detail of the air-escape regulator.
  • 5 indicates generally a collector-casing, herein illustrated as comprising a cylindrical portion 5, a conical portion 5, terminating at its lower end in an axial dustoutlet spout 5, and a deck 5 covering the upper end of the cylindrical portion 5 and provided with an air-outlet 5, preferably concentric with the aXis.
  • collector-casing herein illustrated as comprising a cylindrical portion 5, a conical portion 5, terminating at its lower end in an axial dustoutlet spout 5, and a deck 5 covering the upper end of the cylindrical portion 5 and provided with an air-outlet 5, preferably concentric with the aXis.
  • Other forms of collector-casing known in the art may obviously be employed in the practice of my invention, and I have adopted the standard form herein shown merely as illustrative of an operative embodiment thereof.
  • I provide one or more deflecting instrumentalities arranged to deflect air from within a peripheral belt to the air-outlet 5 the course of deflection making not more than a single circuit of the machine.
  • a deflector instrumentality 9 preferably curved in plan and eccentrically arranged relative to the casing 5, so that it extends to some point adjacent to but out of contact with the casing part 5 to and preferably into longitudinal alinement with the air-outlet 5
  • the deflecting instrumentality 9 as composed of three sections 9, 9", and 9", eccentrically arranged relative to each other, so that the end of the deflector 9 farthest removed from the casing 5 lies in the rear (with reference to the direction of rotation of air in the casing) of the forward end of the next deflector 9 which in turn overlies the forward end of the innermost deflector 9.
  • the vertical extent of the deflector is preferably equal to or greater than the height of the inlet-spout 6, and its angular measurement with reference to the casing-axis should not exceed three hundred and sixty degrees.
  • the deflecting agency is as short as is practically possible without presenting too abrupt an angle to the circular path which the air tends to take in the casing, so that it serves to deflect the air as sharply as proper practice will warrant.
  • the deflector structure, or the various deflector members thereof, is preferably adjustable toward and from the peripheral wall of the casing. I have herein indicated the entire structure as being adjustable as a unit and to such end provide in the plate 8 slots 11, with which engage bolts 12, takinginto the deck 5 of the casing.
  • I also preferably employ in conjunction with my deflector structure an apron 13, which may be of less height or vertical extent than the deflectors and extends from a point where the deflector structure intersects the edge of the outlet around the periphery of said outlet for any suitable distance less than the whole circumference of the outlet.
  • an apron 13 which may be of less height or vertical extent than the deflectors and extends from a point where the deflector structure intersects the edge of the outlet around the periphery of said outlet for any suitable distance less than the whole circumference of the outlet.
  • I also preferably employ in conjunction with my machine a means for regulating and con trolling the delivery of air to the air and dust outlet, which means I have also found controls the manner of delivering the dust through the outlet-spout.
  • This means comprises, essentially, a governing-plate 14, preferably of circular or disk form, arranged to cover a portion of the air-outlet 5.
  • the plate 1 L is preferably universally adjustable within the plane of the outlet 5
  • I mount upon the top of the casing a guide-ring 15, with which engages a strap 16, adapted to be secured with relation to the ring 15 by any suitable means, such as a setscrew 17, and mount the plate 14 upon the said strap 16 so it may be adjusted longitudinally of said strap, such attachment being preferably'made of a clip 18, provided with a setscrew 19.
  • the dust-laden air tends to take a spiral downward path in the casing to some point where the pressure of the incoming air overcomes the resistance of centrifugal effect, where said air will travel inward toward the axis of the casing and thence upward through the axial outlet, the dust (or a major portion thereof) continuing in its travel 'down the casing-walls to the point of escape.
  • my improved machine when the material has about completed its first circuit of the deflector and escape through the tangential valve-openings 10 and 10 back into the incoming current.
  • a casing wherein the dust-laden air whirls, having an inlet for the dust-laden air and an air-outlet, in combination with a deflector extending from a point within the casing out of contact with the wall thereof to the air-outlet and making not more than a single turn about the axis of the easing, said deflector being arranged with its outer end in a path of the air in its first circuit of the casing.
  • a dust-collector in combination with a casing wherein the dust-laden air whirls, having an inlet for the dust-laden air, and an air-outlet, of means in substantially the plane with the inlet for deflecting air sharply from within a peripheral belt to the air-outlet.
  • a casing wherein the dust whirls having a tangential inlet for the dust-laden air, and an axial air-outlet, in combination with a deflecting instrumentality in the path of the air in its initial circuit arranged to deflect portions of the air within a peripheral belt to the air-outlet, said deflecting instrumentality having an angular measurement of not more than three hundred and sixty degrees relative to the axis of the easing and being provided with tangential dustvalve openings.
  • a casing wherein the dust-laden air whirls, having a peripheral tangential inlet for the dust-laden air, and an axial air-outlet, in combination with a deflecting instrumentality intersecting the path of initial circuit of the air, and extending to the air-outlet and adjustable to vary the distance of its outer end from the oasing-wall.
  • a dust-collector the combination with a casing wherein the dust-laden air whirls, having an inlet for dust-laden air, and an airoutlet near its axis, of a curved deflector eccentrically disposed relative to the casing in the path of initial circuit of the air, extending, with reference to the direction of rotation of the air, in a concave curve of less than three hundred and sixty degrees angular measurement from a point near the casing-wall to the air-outlet.
  • a deflecting instrumentality intersecting the path of initial circuit of the air and extending from a point adjacent the peripheral wall of the casing toward the air-outlet, said instrumentality comprising a plurality of curved plates which jointly make less than a single turn about the outlet, said plates being eccentrically disposed relative to the casing, and each having its outer end at a less radial distance from the casing-axis than the proximate end of the adjacent-plate.
