SPECIFICATION forming part of Letters Patent No. 403,701, dated May 21, 1889.
Application filed January 3, 1888- Serial No. 259.594.
(No model.) Patented in Germany September 1, 1887, No. 44,377; in
France September 12,1887,No. 185,792; in Belgium September 12, 1887, No. 78,842; in England September 13, 1887, No. 12,425; in Italy September 30, 1887, N0. 22,3 10/202, and in Austria-Hungary March 6,1888,N0.85,486 and No. 67,092.
To all whom, it may concern:
Be it known that I, HEINRICH Seen, a subject of the Emperor of Germany, residing at Dresden, Saxony, Germany, have invented certain new and useful Improvements in Dust-Collectors, (for which 1 have obtained Letters Patent in Germany, September 1, 1887, No. 44:,377; France, September 12, 1887, No. 185,792; Belgium, September 12, 1887, No. 78,842; England, September 18, 1887, No.12,425; Italy, September 30, 1887, No. 22,340/202, and Austria-Hungary, March 6, 1888, Nos. 35,436 and 67,092,) of which the following is a full, clear, and exact specification.
This invention has for its obj eet to provide a novel and efficient apparatus for freeing air from dust, such as sawdust, particles of flour, and other impurities; and it consists in the features of construction and combination of devices hereinafter described and claimed, reference being made to the accompanying drawings, illustrating my invention, in which Figure 1 is a vertical central section of the apparatus; Fig. 2, a top view of the rotating bodies shown in Fig. Fig. is a vertical central section showing a modification of the apparatus, the same being here provided with curved blades of metal, wood, or the like, for the purpose of producing the draft of air required.
In order to enable those skilled in the art to make and use my invention,I will now describe the same in detail, referring to the drawings, wherein The letter d indicates a suitable casing, in which is located a vertical shaft, 0, having a number of fixed hubs, 1'), arranged at short distances one above another, and carrying a number of spokes or arms, a, from the lower surfaces of which are suspended a number of rings, 2'.
The rings '6 are in the form of annular bands which successively increase in diameter from the inner to the outer one, and, as shown, the bands are located in stepped form, so that the lower edge of one extends below the lower edge of the adjacent one, commencing from the bottom ring or band to the top ring or band. The bands are all separated from each other at the top and bottom and at all other points, except as to the spokes a, by wide intervening annular air-spaces for the free upward passage between them of the air to be deprived of dust and purified. This separation of the bands at the top and bottom is important, in that it provides for the free upward passage of the air between rings and the deposition of the dust on the inner surfaces of the rings or bands by centrifugal force. The stepped arrangement of the rings or bands also provides for efficiently depriving the air of dust, in that such dust which is not held by one ring or band will be held by the next ring or band. To produce an effective apparatus for the purposes of this invention, it is desirable, also, to use scrapers f, preferably stationary, and to permit such scrapers to properly perform their function the rings or bands must be annular and perfectly and continuously smooth throughout their extent on their inner vertical faces, so that the stationary scrapers f, hereinafter described, can rest directly against such continuously-smooth inner faces of the revolving bands to effectually and evenly scrape off the adhering dust.
The casing of the apparatus is provided with an inlet, 0, for the dust-laden air at its lower end, through which the said air is introduced into the apparatus.
Suitable means (not shown) are provided for rotating the vertical shaft 0, and with it the different series of concentric rings 1', thereby causing the dust, &c., to be forced and held against the inner surfaces of the said rings 01. Each series of rings has below it an inclined gutter, 7c, extending directly beneath the scrapers fihereinafter set forth, and attached to or forming part of the box or easing (Z of the apparatus, by means of which the dust after being scraped off from the rings is conveyed out of the apparatus, there to be removed by means of a conveyor, 71, Fig. 1,which may be arranged in any suitable place near the lower part of the apparatus; or, instead of one such conveyer it being arranged in the lower part of the apparatus, there may be a number of conveyers, (not shown,) one for each gutter, so that the dust from each series of rings may be collected and removed independently, as will be readily understood. The object of this last-named arrangement would suction.
be to remove the finer-grained dust of the upper series apart from the coarser dust of the lower ones.
For scraping off automatically the dust collected 0n the inner surfaces of the several rings 2' during the rotation of the latter, a number of upright pieces of metal,wood, or other suitable materialthat is to say, scrapers f may be attached to the upper surfaces of the said gutters in such a way asto gently bear against or merely to touch the inner surfaces of the rings 71 and to remain stationary while the rings are rotated, thereby performing a scraping action against the said rings and causing the dust to drop into the gutters below.
The apparatuses vmay be arranged either horizontally or, as it is shown in the drawings,
- vertically,and the air to be thus purified may either be forced into the apparatus by means of a blower or passed through it by means of In the latter case the sucking action may as well be produced by means of a fan composed of suitable curved plates, Z, as sh own in Figs. 2 and 3,fastened upon the rings t'and rotating with the same within the outer casing, cl.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, .is
1. In a dust collector, the combination of a closed casing having an inlet for the dustladen air, an outlet for the purified air, and an exit for the collected dust, a revolving shaft, a series of vertically-arranged concentric rings connected to the shaft with their sides substantially parallel thereto and to each other and provided with free and unobstructed openings between both their upper and lower edges, and means, substantially as described, for moving the dust-laden air in through the openings between the rings at one edge and the purified air out through the openings between the opposite edges of the rings, whereby the latter force the impurities by centrifugal force against their interior surfaces and the air entering the openings between the lower edges of the rings passes off through the openings between the ,upper edges of said rings, as set forth.
2. In a dust-collector, the combination of a casing having closed side walls, an inlet for the dust-laden air, an outlet for the purified air, and an exit for the collected dust, a rotary shaft, a series of parallel vertically-arranged concentric rings, all connected with the shaft, provided with free and unobstructed openings between their upper and lower edges and having the lower edge of one extended below the lower edge of the adjacent ring in stepped form, and air-forcing mechanism for moving the dust-laden air through the openings between the rings at one edge and the purified air out through the openings between the opposite edges of the rings, substantially as described.
3. In a dust-collector, the combination of a closed casing having an inlet for the dustladen air, an outlet for the purified air, and a discharge-opening for the collected dust, a revolving shaft, a series of vertically-arranged concentric rings connected to the shaft with their sides substantially parallel thereto and to each other and provided with free and unobstructed openings between both their upper and lower edges, means, substantially as described, for moving the dust-laden air in through the openings between the rings at one edge and the purified air out through the openings between the rings at their opposite edges, and dust-receivers 'belowthe rings and in communication with the dust-discharge opening.
4-. In a dust-collector, the combination of a casing, a rotating shaft therein, a series of concentric annular rings having smooth inner vertica1ly-arranged faces and separated from each other at their top and bottom edges to provide for the free upward passage of air between the rings, scrapers acting to scrape the dust from the smooth inner vertical faces of the rings, and a fan for passing the air to be purified between the rings, substantially as described.
5. In a dust-collector, the combination of a casing, a rotating shaft therein, concentric rings separated at their upper and lower edges by intervening air-spaces and arranged in stepped form, with the lower edge of one projecting below the bottom edge of the adjacent one from the ring at the bottom to the ring at the top, and a fan for passing the air to be purified between the rings, substantially as described.
6. In a dust-collector, the combination of a casing, a rotating shaft therein, a series of concentric annular rings separated from each other at their top and bottom edges by intervening air-spaces to provide for the free passage of air between the rings and having vertically-arranged inner faces, scrapers for detaching the accumulating dust on said vertically-arranged inner faces, and a gutter extending under the lower edges of the rings directly beneath the scrapers to receive the dust detached by the latter, substantially as described.
7. In a dust-collector, the combination of a series of rotating rings arranged concentrically, whereby the impurities are driven out of the air forced into and through the apparatus, in combination with scrapers for removing the dust adhering to the said rings, and with curved plates fastened upon the latter, substantially as and for the purpose set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
