This invention relates to a device by which fine particlesof material or powder, that are conduit may be divided in such a mannerthat equal proportions of air and solid materlal are passed into the respective branches. It is well known that when powdered coal, for
example, is carried by air through a conduit the coal sometimes becomes concentrated along one side of the conduit so that if a branch istapped off from that side the proportionof coal to theair-is greater than in the main conduit making that in the branch too rich in coal, While a branch tapped oft fromanother portion wouldjbe too lean in coal. By thepresent invention this obj ection can be avoided and the proper distribution of coal inthe air in the difl'erent branches is obtained. The invention will be understood from the description in connectionwith the accompanying drawings in which Fig. 1 is a section of an illustrative embodiment of the invention taken along the line 11 of Fig. 2;
Fig. 2 is a side elevation of the device; Fig. 3 is an end view of the same; Fig. 3 is a perspective view of some of the parts on a small scale; Fig. 4 is a section similar to Fig. 1 taken along the line 4-4 of Fig. 5 showing a modification; Fig. 5 is a side view of the modification; and Fig. 6 is an end viewof the same.
In the drawings reference character I indicates a casing that is provided with an inlet 2 on the side which leads from a conduit from which branches are provided. The casing 1 contains a cylindically shaped propeller compartment 3 in which a propeller is mounted comprising the propeller shaft 4 that is journaled in the bearing 4 on the easing, and axially disposed blades 5 that are preferably slightly curved extending from the shaft 4 in radial directions. The blades comprise two groups 5 and 5, the group 5 being substantially as wide as the axial dimension of the compartment 8 and the group 5 being approximately half that width. The blades 5 and 5 alternate with each other around the propeller wheel. The shaft 4 may be driven from any convenient source of power (not shown) so that the pro- 1928. Serial mi. 273,541;
be driven atany desired speed. 1 carried by a stream of air or gas through a A division plate 6 is located about half way between the ends of the cylindrical compartment 3 and is provided with ring shaped angles 17 that are attached to the plate 6, the
inner flanges terminating near the outer periphery of the blades 5 and 5'. Somewhat trial igularly shaped baffles8 are installed at the inner edges of theblad-es 5 these baffles fciosing the alternate spaces between the blades 5and 5 and being perpendicular to these blades. The baflles 8 have flanges 9 parallel to the blades 5 extending toward the inlet 2 andclamping screws 10 are provided on the blades 5 and 5 passing through slots in the flanges 9 so that the baffles 8 canbe adpisted axially on the blades 5 and 5. The combined width of the inner flanges of the angles 7 is sufficient to suit the different posi- 9 tlons of the battles 8 and to cover the range of adjustment of these bafiies. A pair of outlets 11 and 11 extend from the lower side of the casing 1,=being disposed on the opposite sides of the division plate 6. By making the battles 8 adjustable, means are provided for diverting difierent amounts of material into the different outlets 11, 11.
The operation is as follows: The gas or air carrying'jthe particles of solid material in suspension enters through the inlet 2 while the shaft 4 and blades 5 and 5 are being driven. A portion of the air andsolid particles enters the spaces between the blades 5 and 5 that are closed by the batfles 8 and sizes, substantially equal amounts of the material will be carried into the respective branches 11 and 11. IIowever, by making the sets of entrances of different sizes, different amounts of material can be diverted into the respective branches. In view of the face that each opening between the blade 5 and blade 5 sweeps over the entire area of the inlet 2, the average concentration of solid I material in the air will be the same for each blades carried by said wheel,
opening, and therefore the proper proportion of air to solid material will be carried off by the branches 11 and 11.
In the modification shown in Figs. 4, 5 and 6, the blades 5 and baffles 8 are dis pensed with and the blades 12 that alternate with the blades 5 are bent near themiddle and the bent ends 13 are turned and shaped so as to come into contact. with the blades 5 at right angles thereto, thus closing the alternate ends of the spaces between the blades 5 and 12. The operation is similar to that above described in connection with the other modification.
I claim:
1. In a device of the character described, a casing, a wheel having radial blades thereon revoluble in said casing, baffles on said wheel extending between alternate pairs of blades, and a division plate attached to the inside of said casing substantially in alignment with said baflles.
