- Many forms of dust collectors are now in use embodying broadly the principle of separating one body from another by utilizing the difference in specific weights of the bodies to efiect the separation, the most common form being the type commonly known as the cyclone type of collector.
- This collector imparts a whirling motion to the bodies which are being separated, whereby the heavier body, possessing greater centrifugal force than the lighter body, is directed outwardly from the axis of whirl with a greater force than that of the lighter body, the path of the lighter body in the direction of the axis of whirl being unobstructed, while the path of the heavier body in the direction of the axis of the whirl is obstructed, thus effecting the separation of the two bodies.
- the present invention concerns itself with the details of construction including the means for eilecting a substantially complete separation of the heavier body from the lighter body and an object of the invention is, accordingly, to provide a separating and collecting device of the above character wherein means is provided to separate the heavier body from the lighter body by obstructing the flow of the former in the direction of the axis of the whirl imparted to the two bodies, such obstruction being effected without interference with the flow of the lighter body in the direction of the axis of the whirl.
- a further object of the invention is to provide a device of the above character, wherein the flow of the separated body, after separation from the lighter body, is directed to a desired destination in such fashion as to P event the formation of eddy currents and other disturbing influences whereby the flow of the separated body is efiectively controlled.
- a further object of the invention is to provide a device for effecting the separation of one body from another by means of a plurality of independent separating elements so disposed that the body separated from all of the elements is directed into a common fluid stream and carried to a desired objective.
- a further object of the invention is to provide a separating and collecting device of the above character wherein a plurality of superposed separating elements are spaced with respect to a (El. Edit-39) plurality of other such elements in such fashion that the separated body from all of the elements is directed into a common fiuid stream, means being provided to constrain the ilow of the separated body in a uniform and substantially lamel- 5 lar fashion.

- a separating and collecting device is illustrated as having a separating chamber in, collecting hopper ii, and an exhaust it through which is discharged the quantity of the medium from which 5 a body is to be separated, which quantity is taken from the separating devices simultaneously with the body or medium to be collected.
- the combined bodies are introduced through an inlet l3 formed in the housing l0 and the body from 40 which separation is effected is discharged through the outlet H, the path of this body thus being straight through the separating device.
- a plurality of spaced vertical rows of separating elements or cham- 45 bers are provided, these rows being illustrated in Figure 2. While the number of rows constitutes no part of the present invention, the device described herein is shown as embodying four vertical banks of separating elements arranged in two groups of two vertical banks each. Between the two groups of banks, a vertical passage I5 is formed, this passage being illustrated in dotted lines in Figure 2. Upon the outer side of the groups of banks, additional passages it are provided, these passages communicating with the outlet
- each independent separating element will be seen to include a wind tunnel ll having one side thereof formed with a longitudinal slit l8, this slit being formed by expanding one edge of the slit to a greater radius than the other, thus affording an outlet for a body travelling about the inner periphery ofthe tunnel in the direction of the surface of the expanded edge.

The present invention relates to apparatus for separating bodies of different weights from one another and embodies, more specifically, an improved form of device for separating and col- 5 lecting dust from air. Many forms of dust collectors are now in use embodying broadly the principle of separating one body from another by utilizing the difference in specific weights of the bodies to efiect the separation, the most common form being the type commonly known as the cyclone type of collector. This collector imparts a whirling motion to the bodies which are being separated, whereby the heavier body, possessing greater centrifugal force than the lighter body, is directed outwardly from the axis of whirl with a greater force than that of the lighter body, the path of the lighter body in the direction of the axis of whirl being unobstructed, while the path of the heavier body in the direction of the axis of the whirl is obstructed, thus effecting the separation of the two bodies. Inasmuch as the known literature describes broadly mechanism embodying the foregoing characteristics, the present invention concerns itself with the details of construction including the means for eilecting a substantially complete separation of the heavier body from the lighter body and an object of the invention is, accordingly, to provide a separating and collecting device of the above character wherein means is provided to separate the heavier body from the lighter body by obstructing the flow of the former in the direction of the axis of the whirl imparted to the two bodies, such obstruction being effected without interference with the flow of the lighter body in the direction of the axis of the whirl.
A further object of the invention is to provide a device of the above character, wherein the flow of the separated body, after separation from the lighter body, is directed to a desired destination in such fashion as to P event the formation of eddy currents and other disturbing influences whereby the flow of the separated body is efiectively controlled.
A further object of the invention is to provide a device for effecting the separation of one body from another by means of a plurality of independent separating elements so disposed that the body separated from all of the elements is directed into a common fluid stream and carried to a desired objective.
A further object of the invention is to provide a separating and collecting device of the above character wherein a plurality of superposed separating elements are spaced with respect to a (El. Edit-39) plurality of other such elements in such fashion that the separated body from all of the elements is directed into a common fiuid stream, means being provided to constrain the ilow of the separated body in a uniform and substantially lamel- 5 lar fashion.
Further objects, not specifically enumerated above, will be apparent as the invention is described in greater detail in connection with the accompanying drawings, wherein:
Figure 1 is a view in side elevation, showing a separating and collecting device construced in accordance with the present invention and including a plurality of individual separating elements mounted in accordance with the present invention.
Figure 2 is a view in end elevation, showing the device of Figure 1.
Figure 3 is a detail view showing one of the separating elements constructed in accordance with the present invention.
Figure 4 is a detail view in section, taken on a plane passing through an intermediate portion of a plurality of superposed and spaced separating elements mounted as shown in Figures 1 and 2.
Figure 5 is a detail view similar to Figure 3, showing a modified form of separating element.
Figure 6 is a view similar to Figure 4, showing the manner in which the elements of Figure 5 are mounted in a collector.
With reference to Figures 1, 2, 3, and 4, a separating and collecting device is illustrated as having a separating chamber in, collecting hopper ii, and an exhaust it through which is discharged the quantity of the medium from which 5 a body is to be separated, which quantity is taken from the separating devices simultaneously with the body or medium to be collected. The combined bodies are introduced through an inlet l3 formed in the housing l0 and the body from 40 which separation is effected is discharged through the outlet H, the path of this body thus being straight through the separating device.
Within the housing iil,-a plurality of spaced vertical rows of separating elements or cham- 45 bers are provided, these rows being illustrated in Figure 2. While the number of rows constitutes no part of the present invention, the device described herein is shown as embodying four vertical banks of separating elements arranged in two groups of two vertical banks each. Between the two groups of banks, a vertical passage I5 is formed, this passage being illustrated in dotted lines in Figure 2. Upon the outer side of the groups of banks, additional passages it are provided, these passages communicating with the outlet |2 of the device.
With reference to Figure 3, each independent separating element will be seen to include a wind tunnel ll having one side thereof formed with a longitudinal slit l8, this slit being formed by expanding one edge of the slit to a greater radius than the other, thus affording an outlet for a body travelling about the inner periphery ofthe tunnel in the direction of the surface of the expanded edge. For a portion of the circumference of the tunnel l1, therefore, the contour does not follow a truly cylindrical path but diverges outwardly in a suitable spiral fashion.
The tunnel flares outwardly at either end from the substantially cylindrical section to squared sections l9 at the entering end and 2|] at the exhaust end. F uting 2| is formed therein to effect this transformation in contour of the tube. In the intake end I9 of each tube is provided a vane or vanes 22 formed about a central hub 23 and curved in such fashion that the flow of the medium entering the tube will be changed to a whirling motion having not only a component in the direction of the axis of the tube but a component in a direction transverse to the axis thereof. The pitch of the vanes 22 is such as'to cause the direction of whirl to follow the direction of the expanded edge of the longitudinal slit and thus the heavier bodies carried by the entering medium are directed outwardly against the internal surface of the wind tunnels and escape through the longitudinal slits I8.
The substantially cylindrical portion ll of each tube is formed with a rectangular housing 24 which is formed with a longitudinal slot 25 to receive the protruding portion of the expanded portion iii of the tunnel. At spaced points along the length of the slotted side of the housing 24, vertical vanes 26 are secured, these vanes lying in planes perpendicular to the axis of the housing 24 and preferably being so spaced as to cooperate with the corresponding vanes of adjacent tubes to form substantially continuous vertical channels. The size of the vanes is such that they not only abut with cooperating vanes .of tubes in the same horizontal plane but with the corresponding vanes of cooperating tubes in the vertically spacedbanks of tubes. Each of the vanes 26 is formed with a cut out portion 21 to receive the expanded edge I8 of the respective tubes and it will thus be seen that the cooperating vanes form vertical channels into which the separated body from the separating tube I1 is directed downwardly (see Figure 4).
In the upper portion of the hopper longitudinally extending deflector plates 28 may be provided, a partition 29 serving to separate the hopper into a plurality of sections, each provided with deflecting plates 28. The deflecting plates need not be used if the velocity of the separated medium is reduced sufficiently after emerging from the slits IS, the body separated by the separating devices being collected in the hopper II and air or other medium carried over with the separated and collected body being discharged upwardly through side channels 30 into the outlet I2.
With reference to the construction shown in Figures 5 and 6, the independent separating elements comprise an intake tube 3| which may be of rectangular cross section and formed with vanes 32 corresponding with the vanes 22 of the device described in connection with the construction shown in Figure 3. The tube 3| is formed with a conical converging portion 33 which terminates in a cylindrical portion 34 and an outwardly flaring skirt 35/ Axially disposed with respect to the intake tube 3| is an exhaust tube formed with a squared extremity 36 and an elongated tapering tubular portion 31 having an inlet end 38 which is received within the skirt 35 and is of a diameter less than that of the cylindrical portion 34 of the tube 3|. A desired overlap of the skirt and intake end 38 of tube 36 is provided, the tubes being secured together by oppositely extending vanes 39 which are riveted to the respective tubes. Vanes 39 are formed with a straight outer edge 40 and an inner edge which conforms to the contoursof the adjacent portions of the tubes 3| and 36. Between the portions of the vanes secured to these tube portions, however, curved recessed portions 4| are formed to permit a limited degree of whirling motion of the separated body after it leaves the skirt 35.
In assembling the tubes shown in Figure 5, the
In the construction shown in Figures 5 and 6, therefore, it will be seen that the medium is introduced at 3| into the vanes 32 which impart a whirling motion thereto. The heavier body is thus directed very forcefully outwardly against the converging surface of the conical extension 33 of the tube 3| and, when it reaches the cylindrical portion 34, a vortex has been created, the outer portion of which comprises the heavier body and the inner portion of which the lighter body. As the medium passes through the cylindrical portion 34, the heavier body will thus follow the outwardly flaring skirt 35 and escape from the separating chamber, while the lighter body passes into the tube 31 to be discharged through the outlet 36.
As shown in Figure 6, the partition walls 39 of vertically adjacent separating chambers abut to define the walls of a passage through which the heavier substance is discharged from a series of horizontally and vertically spaced separating chambers. These walls break up the whirling motion of the heavier substance as it leaves the separating chamber and direct the same into well defined courses to effect the separation and collection thereof.
It will thus be seen that the separating devices above described form a venturi through which the fluid passes in a uni-directional fashion. The inlet chamber of the venturi is formed with a converging portion into which the fluid is directed with a whirling motion and the outlet chamber of the venturi is formed with a taper to provide an expansion chamber. At the throat portion of the venturi, separation of the solid particles from the gaseous or lighter particles takes place.
While the invention has been described with specific reference to the accompanying drawings, it is not to be limited, save as defined in the appended claims.
