Definitions
- FIGA W is a diagrammatic representation of FIGA W.
- This invention relates to an atomizer wheel for the atomization of suspensions of hard-wearing materials and of the type which concentrically with the hub of the wheel has an annular bowl-shaped space in the substantially cylindrical outer wall of which there are provided a plurality of discharge openings having linings of a wear-resistant sintered material.
- sintered materia means a material where the hard grains are stably interconnected no matter whether such interconnection has been effected by fusing together the surfaces of the grains or by embedding the grains in some basic substance such as, by Way of example, is being used in the manufacture of Wolfram carbide bodies.
- ticles for example a suspension of ceramic clay
- a very hard wear is taking place on account of the very high velocities of discharge from the atomizer wheel caused by the centrifugal force.
- a conventional atomizer wheel made of the commonly used wear-resistant types of steel will have an extremely short lifetime, sometimes only a few hours or even less before they have become so heavily worn as to be entirely unserviceable.
- the invention has for its object to provide an atomizer wheel of the type concerned in connection with which a very considerable increase of the lifetime is obtained.
- One object of the invention is to provide the holes with linings of tapered bushings of wear-resistant sintered material, projecting into the bowl-shaped space.
- the coating thus obtained is, to be sure, not wear-resistant in the proper sense of the word in that it consists of loosely interconnected particles which are inceimpulsly torn way from the surface of the layer by the suspension flowing towards the openings of the bushings but the centrifugation of particles out into said layer will continuously have the effect that the torn-away particles are replaced by fresh particles so that the parts of the coating adjoining the wall are preserved and preclude any wear of said wall. In practice it proves that in this way lifetime can increase several hundred times.
- the bushings consist of the said wear-resistant sintered material, they will nevertheless be subject to wear but they are readily replaceable because they are only kept in place by the centrifugal force which, as a matter of fact, is inoperative when the wheel is at rest.
- the wear to which the bushings are exposed is unilateral and their lifetime may, therefore, be increased by turning them gradually as they are worn.
- the openings of the bushings may by way of example have a circular cross section but preferably they are of a square cross section.
- the square cross section determines four different well-defined positions of the bushings. Further the wearing surfaces are plane which has proved to involve a longer lifetime than curved wearing surfaces.
- a wearing groove may be produced in the annular space at the place where the surface of said coating adjoins the bottom of the wheel. This wear may be essentially reduced when the bottom of the bowl-shaped space has a conical shape sloping outwardly towards the outer wall.
- a layer of a wear-resistant material is provided on the bottom surface of the bowlshaped space made for either in the shape of an embedded annular plate or a sintered surface coating at any rate in the outermost part of the bottom surface.
- the wear may be less hard than in the bushings proper and through a surface coating of wear-resistant material it is possible to obtain the advantage that the lifetime of the wheel proper becomes of a length sufficient for permitting the bushings being replaced a number of times before the wheel is discardable. If using an embedded ring this ring can also be replaced and, consequently, the longest imaginable lifetime of the wheel is attained.
- FIG. 1 shows a sectional view an embodiment of the atomizer wheel according to the invention.
- FIG. 2 the same atomizer wheel as seen from the supply side.
- FIG. 3 shows a modified embodiment of the atomizer wheel in a sectional view.
- FIG. 4 a modification of a part of the atomizer wheel shown in FIG. 1 or 3.
- the wheel illustrated in FIG. 1 is substantially of bowlshape with a centrally disposed hub 1 whereby an annular space 2 appears between the hub 1 and the outer wall 3 of the wheel which space is further defined by the wheel portion 4 connecting the hub 1 with the outer wall 3 and forming the bottom of the annular space 2. Further, an annular cover plate 5 is secured to the upper side of the wheel, said cover plate surrounding the hub 1 in such a manner as to form between said hub and the annular plate 5 an annular opening 6 leading into the space 2.
- the wheel is intended for being mounted into a known spray-drying apparatus on a shaft which during operation rotates at a very high velocity, a suspension being supplied to the space through the opening 6 and precipitated in atomized form through openings in the side wall 3 to a surrounding drying chamber wherein the fine particles formed by the atomization are dried so that their contents of solid matter fall to the bottom of the drying chamber in the form of a fine powder.
- FIGS. 1 and 2 show a single one of said openings, and according to the invention a bushing 7 of a wearresistant sintered material, for example Wolfram carbide, silicon carbide, aluminium oxide or tetraboron carbide, is disposed in each of said openings.
- a wearresistant sintered material for example Wolfram carbide, silicon carbide, aluminium oxide or tetraboron carbide
- These bushings 7 have conical outer surfaces with outwardly decreasing diameter and, consequently, they can be loosely disposed in said openings as they are pressed outwardly by the centrifugal force when the Wheel is rotated and, consequently, they are immovably and tightfittingly secured in the openings in the outer wall.
- the bushings 7 are preferably ground flush with the cylindrical outer surface of the wheel whilst their inwardly facing ends extend a distance into the space 2 beyond the outer wall 3 as seen in FIG. 1.
- a certain Wearing effect may occur at the bottom of the space 2 and primarily at the vicinity of the bordering line 8 for the material deposited on the outer wall 3.
- an annular plate 9 of a wear-resistant material is embedded at the bottom of the space. If deemed appropriate, this material may likewise be a hard sintered material but since this area is subject to somewhat less wear it will often suffice to use a wear-resistant metal alloy, for example a wearresistant type of steel.
- FIG. 3 differs from that shown in FIG. 1 in that instead of the annular plate 9 a layer 10 of a wear-resistant material has been applied to the bottom of the space 2, said layer extending a distance upwardly along the hub 1. Since the said layer is not replaceable in the same manner as that used in FIG. 1, it may be expedient that said layer consists of a wearresistant sintered material.
- FIG. 4 shows a modified embodiment of the bushings having square cross-section instead of circular crosssection as shown in FIGS. 1 and 3.
- the bushings are tapered at least over part of its length 11 corresponding to the conical part of the bushings 7 in FIGS. 1 and 3.
- the bottom of the annular space may be conically sloping outwards from the hub 1 as indicated in FIG. 1 by means of a dotted line 12.
- An atomizer wheel comprising a hub, an outer wall part coaxially disposed about said hub and a bottom part connecting said outer wall part with said hub, said outer wall part, said hub, and said bottom part defining between them an annular chamber, a ring-shaped cover member detachably connected to said outer Wall part, said cover member having an inner circumference defining together with said hub an unobstructed space in communication with said annular chamber, said outer wall part being provided with a plurality of regularly shaped holes uniformly distributed around the circumference of the outer wall part, said holes forming the only outlet openings of the wheel, each of said holes being lined with bushing of wear-resistant sintered material, said holes and said bushings being tapered in direction radially outwardly from said chamber, the inner end of each of said bushings projecting into said chamber while their outer ends are substantially flush with the outside of said outer wall part.
- An atomizer wheel comprising a hub, an outer wall member coaxially disposed about said hub, a bottom member connecting said outer wall member with said hub, the upper surface of said bottom member being of a wear-resistant material, said outer wall member, said hub, and said bottom member defining between them an annular chamber, a ring-shaped cover member detachably connected to said outer wall member, said cover member having an inner circumference defining, together with said hub, an inlet opening in communication with said annular chamber, said outer wall member being provided with a plurality of uniform outlet openings uniformly distributed about the periphery of the outer wall part and forming 5 6 the only outlet openings of said wheel, and a bushing of 2,695,748 11/1954 Millard 23347 wear-resistant sintered material extending radially through 3,079,069 2/ 1963' Thylefors 23 3-46 X R each opening and projecting into said chamber, said holes 3,094,487 6/1963 Van Arsdell 23346 XR and said bushings being tape
