Fred R. Cordua,
Tex., a corporation of Huber Corporation, Borger,
The present invention relates to an atomizin-g wheel and particularly to a wear-resistant wheel.
In modern atom-izing practices, the material to be dried is suspended in a water slurry and is fed onto an atomizing wheel turning at a high rate of speed. The material engages a plurality of atomizing pins positioned about the perimeter of the wheel and is atomized hereby for contact with a current of gas. The material suspended in the water slurry has an abrasive action on the atomizing wheel, brought about by the inherent abrasiveness of the material and the shearing forces resulting from the high rate of rotation of the wheel. In prior art structures the atomizing wheels have had an extremely short life and a high replacement cost such as to materially reduce the effectiveness of the atomizer as an economic apparatus.
The primary obg'ect of the invention is to provide an atomizing wheel having relatively inexpensive replaceable wear surfaces positioned in the areas of maximum wear of the wheel.
Another object of the invention is to provide an atomizing wheel formed of a plurality of demountable elements such as to permit inexpensive replacement of worn elements when necessary.
A further object of the invention is to provide an atomizing wheel having replaceable wear surface elements formed with a minimum of machining to ensure the lowest possible cost of manufacture.
A still further object of the invention is to provide an atomizing wheel having replaceable wear surface elements formed of hardened abrasive-resistant materials to increase the effective life of the wheel.
An object of the invention is to provide a structure of the class described above in which the replaceable Wear surface elements can be inverted to increase the over-all service of the elements prior to replacement.
Other objects and advantages will become apparent in the following specification when considered in light of the attached drawings in which:
FIGURE 1 is a side elevation of the atomizer wheel;
FIGURE 2 is a top plan view of the wheel as viewed from the line 2-2 of FIGURE 1 looking in the direction of the arrows;
FIGURE 3 is a bottom plan view of the wheel as viewed from the line 3-3 of FIGURE 1 looking in the direction of the arrows; and
FIGURE 4 is a vertical sectional view taken on the line 4-4 of FIGURE 2 looking in the direction of the arrows.
Referring now to the drawings in detail wherein like figures, the reference numeral indicates generally an atomizer wheel constructed in accordance with the invention.
The wheel 10 includes a hub 11 having an axial vertical bore 12 extending therethrough. A rectangular keyway 13 is formed in the bore 12 and is coextensive therewith. The hub 11 is adapted for mounting on a drive shaft 14 shown in broken lines in FIGURES 1 and 4.
The hub 11 has a generally cylindrical lower portion 15 and a radially outwardly extending body 16 integrally formed on the upper end thereof. The body 16 has a flat lower face 17 extending perpendicularly to the axis of the bore 12. An upper face 18 is formed on the body 16 parallel to the face 17 and having a diameter substantially smaller than that of the face 17. A concave frusto-conical surface 19 sloping generally downwardly and outwardly connects the peripheral edges of the faces 17 and 18 as can be best seen in FIGURE 4. The hub 11 including the lower end 15 and the body 16 is formed integrally of easily machined metal. A plurality of circumferentially equispaced threaded bores 20 is formed in the body 16 opening through the lower 'face 17 thereof. The bores 20 are arranged with their axes equispaced outwardly of and parallel to the axis of the bore '12.
A flat disk 21 formed of abrasive-resisting hardened metal is provided with an axial bore 22 to permit the cylindrical lower portion 15' of the hub 11 to extend therethrough. The disk 21 has a plurality of bores 23 arranged therein for aligned relation to the bores 20 of the body 16. A plurality of cap screws 24 extends through the bores 23 into the bores 20 to detachably secure the disk 21 to the hub 11.
A flat annular ring 25 is positioned beneath the outer edges of the disk 21 and is detachably secured thereto by a plurality of cap screws 26 arranged in equispaced relation thereabout. The ring 25 is formed of easily machined material similar to the hub 11. The disk 21 is provided with a plurality of circumferentially equispaced bores 27 arranged in closely spaced relation to the outer edge of the disk 21. The axes of the bores 27 lie on a circle concentric with the bore 12. The ring 25 underlies the bores 27 and is provided with a bore 28 axially aligned with each bore 27 in the disk 21. The bores 28 are substantially smaller than the bores 27 as is clearly shown in FIGURE 4.
A tubular atomizing pin 29 has its lower end seated in each of the bores 27 supported by the ring 25. An annular plate 30 is supported on the upper ends of the pins 29 and has a downwardly and outwardly sloping axial aperture 31 formed therein. The aperture 31 is substantially larger than the bore 22 in the disk 21.
An annular wear plate 32 is positioned in engage ment with the underside of the plate 30 and has an axial bore 33 formed therein slightly larger than the aperture 31. The wear plate 32 has a plurality of bores 34 formed therein to receive the upper ends of the pins 29. A plurality of bevel-head screws 35 secure the annular plate 30 and the annular wear plate 32 together. The annular plate 30 has a countersunk bore 36 arranged therein axially of each of the bores 34 in the wear plate 32 and somewhat smaller than the bores 34.
A bevel-headed bolt 37 extends through the annular plate 30, through each of the tubular pins 29 and through the annular ring 25. A nut 38 is mounted on each of the bolts 37 to lock the disk 21, ring 25, plate 30, wear plate 32, and the pins 29 into a rigid operating unit. The plate 30 is formed of easily machined material similar to ring 25, and wear plate 32 is formed of abrasion-resisting hardened material similar to the disk 21. The tubular pins 29 are also formed of material similar to the disk 21 and wear plate 32.
In the use and operation of the invention, the abrasive wear on the wheel 10 occurs chiefly in the area adjacent the opposite ends of the pins 29. The disk 21 and wear plate 32 being formed of hardened material will wear much more slowly in these areas than will conventional materials. In addition to wearing more slowly, the disk 21 and plate 32 are each identical top and bottom so that they may be inverted after wearing on one side to provide additional wear on the opposite side.
The disk 21 and wear plate 32 are each of a flat annular form and can be produced without resorting to expensive machining or other costly fabricating processes, The hub 11, while requiring machining to produce, receives practically none of the wear and is formed of relatively inexpensive easily machined material. The hub 11 will outlast a great number of disks 21 and wear plates 32 so that the cost of wheel replacement is materially reduced by following the teachings of the invention described above.
Having thus described the preferred embodiment of the invention, it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the scope of the appended claims.
