' In Germany Novemben;
This invention relates tozapparetus for, Sepe-V rating solid particles from air or other gases.
It Ais a particular aimof the present invention .to vp royide means .for facilitating the flOW ,Of the r, Y 4material to be separatedgto the `*collecting cham .ben through nevel VIneens Which diminishes ,the pressure in the collecting chamber' withrespect Ito Vthe pressure in the separating chamber.
The more speciiic objects and advantages will i o become apparent from 'a .Consideration ,0f the description following ,taken in connection with accompanying drawing, illustrating 'an oprative embodiment. Y Y
In said drawing:
l Fig. 1 is a View of the apparatus inside elevation;
Fig. V2 is a left hand end elevation thereof, and Figy Iisaside.elevation Vof a modied form of the apparatus'.v Y 0 Referring specically to the drawing wherein like reference characters designate like or similar parts in the different views, I designates a separating drum or chamber which is cylindrical and of maximum internal area at its receiving end, which may be extended by a cylindrical preseparator 3. The inlet is shown at 4 and is tangentially disposed and provided in the wall I or extension thereof as shown'in Fig. 1. Disposed across the outer end'of preseparator 3 is 30 a plate 24. Disposed concentrlcally in the drum I and extending partly outwardly beyond the plate 24 is a cylindrical outlet pipe 5, fastened interiorly of the drum by aV support I2 suspended from the upper portion of the drum.
' Said drum I at its rear end portion as shown at 2 is conical so that the incoming gases will rotate and move longitudinally along the inner surface of the drum I with theY path progressively decreasing in diameter at said portion 2.
' 4.0 Substantially centrallyand longitudinally in the lower portionof the wall of portion 2 is an yescape slit or 'opening I9 for solid particles, which slit or opening may berof uniform breadth Vtl'lroughout or be V-shaped as shown, with its ,i5 larger end remote from the inletll. Y w
' Side walls,` preferably flaring downwardly slightly, at 25 and 26 and corresponding front $7* closed by a suitable outlet means at II.
At the Vsmaller Vend 1 ofV drum portion 2 is a plate 8 centrally of which a pipe or conduit I1 55 is connected having a discharge-end atV I8 interiorlyof conical drum Aportion 2. Said pipe or conduit I1 extends through the-rear wall 21 'at one side of the drumf,y 4havingan inlet end I6 'at the top of'the collecting chamberor space ader'ably beingbevelled2 as shown.
Adjacent said `inlet end-I6, a chink or slot 2| fis provided `in slightly oblique direction in :the wall of I by a struckout` portion 23 thereof, such chink fbeing disposed -to produce an io ejectorveifectV f Y ASaidconduit or pipe VI1 at inlet lI8 may -be provided with means 'to set the aspirated gas in rotation, such for instance,V as the scoops22. 'The device described operates inthe following vl5 manner:
y'lhe gas bearing solid particles to be separated enters at the in1e't'3 at thevend of the [drum or separator -having the greatestcross section and Y v it is forced to pass through the separator with 20 simultaneous rotary and longitudinal movement with an increasing angular Velocity by Virtue of the diminishing of the cross section of the path of flow at conical part 2. Under the rotary jphase of such movement the outer layer of the 25 Yspect toY the atmosphere and inv which chamber the particles settle. The gas led to the collecting 30 chamber flows therefrom at I6 into pipe I1 and thence through the pipe I1 to the outlet I8 and into the conical part 2 oi the separator or drum by virtue of the lesser pressure inV that part of the separator, where the main volume of the gas 35 changes its helical movement into fa longitudinal one and at 6 enters the outletpipe 5. The collecting chamber IIJ also being connected with the Vend of the separator or drum I nearest to the gas inlet 3 or with the preseparator 3 by means 40 of the ejector slit 2|, a Viiow of gas will take place from the collecting chamber or drum and also through this; slit owing to the fact that the pressure in the collecting chamber I0 is greater than in the preseparator 3 or that part of the sepa- 45 rator which has the greatest cross sectional area,
but less than the pressure in the conical end 2V of the separator, where the gas iows through the outflow slit I9 to the collecting chamber I0.
Various changes may be made within the spirit 5o and scope of the invention,A and for instance the modif-led form of Figure 3'may be used. This Vform diiers from the preceding formV only in omitting the preseparator. The outlet pipe hereV designated |05 extends into the conical part |02 55 of the drum, the truly cylindrical portion I thereof being omitted. The drum |02 is supported on the collecting chamber H0 which is of a conformable size. The operation is the same as in the precedingA form, and otherwise the structure is the same.
What is claimed is:-
1. Apparatus for separating solid particles from gases consisting of a separating drum, having at one end a considerably larger cross sectional area than at the other end, and having a portion progressively diminishing toward the latter end, a substantially central gas outlet at the first mentioned end, a collecting chamber for the solid particles, the separator having an outflow slit for the separated particles communicating with the collecting chamber, the particles being separated by the gas being forced to follow, under rotation, the progressively diminishing diameter of said portion and then in puried form escape through said outlet, and means providing communication between the smaller end of said portion and the inlet end of the collecting chamber so that the gas rotating under pressure in said smaller end produces a suction in the said means in the direction towards the separator chamber, by which means the over-pressure in the collecting chamber is diminished and consequently the iiow through the said slit is increased in the direction to the collecting chamber.
2. Apparatus for separating solid particles from gases consisting of a separator drum having a pre-separator at one end thereof, said end being of considerably larger cross-sectional area than the other end, said separator having a conical portion diminishing in size toward the other end, a substantially central gas outlet at the rst mentioned end, the wall of said portion having an outow slit for the separated particles communicating with the collecting chamber, the particles being separated by the gas being forced to follow, under rotation, the progressively diminishing -diameter of said portion and then in puried form escape through said outlet and means providing communication between the smaller end of said portion and the inlet end of the collecting ychamber so that the gas rotating under pressure in said smaller end produces a suction p in the said means in the direction towards the A'separator chamber, by which means the overpressure in the collecting chamber is diminished and consequently the ow through the said slit is increased in the direction to the collecting chamber.
3. Device as claimed in claim 1, wherein said means has scoops to set the aspirated gas in rotation.
4. Device as claimed in claim 2, wherein said means has scoops to set the aspirated gas in rotation.
5. Device as claimed in claim 1, wherein the separator chamber and the collecting chamber communicate by means of an ejector opening near the larger end of the separator chamber so that the incoming gas produces a suction from the collecting chamber in the direction to the separator chamber.
6. Device .as claimed in claim 2, having the preseparator connected with the collecting chamber by means oi an ejector opening adjacent the gas inlet end of the device, so that While the gas rotates in the pre-separator a suction is produced from the collecting chamber in the direction to the pre-separator.
