McCausl-and, Rolling Hills, Califl, assignor to Southwestern Engineering Company, Vernon, Califi, a corporation of California Filed Mar. 28, 1960, Ser. No. 17,915 2 Claims. (Cl. 209405) This invention relates to shaking apparatus, and more particularly to shaking apparatus of the type disclosed in the Meinzer Patent No. 2,284,671, issued June 2, 1942.
Included in the objects of this invention are:
First, to provide a shaking apparatus which is divided into sections arranged for ready assembly and disassembly, and which may be combined in different ways to meet specific conditions of use.
Second, to provide a circular shaking apparatus wherein each of the sections thereof having discharge spouts may be adjusted circumferentially 360 so that the discharge spouts may be disposed in any desired position or relationship.
Third, to provide a shaking apparatus wherein the shaker motor and its frame are so arranged that the sections of the shaking apparatus above, particularly the lowermost of said sections is capable of 360 circumferential adjustment.
Fourth, to provide a sectional circular shaking ap paratus wherein the sections are joined by clamp rings, and between which are located mounting rings for screen members, discharge pans, and the like, each section and the mounting rings being so arranged that identical clamp rings may be used to join the sections of the apparatus.
Wtih the above and other objects in view, as may appear hereinafter, reference is directed to the accompanying drawings in which:
FIGURE 1 is a partial side, partial sectional view of the shaking apparatus;
FIGURE 2 is a fragmentary, sectional view taken substantially along the line 2.2 of FIGURE 1 showing portions broken away;
FIGURE 3 is a transverse, sectional view substantially through 33 of FIGURE 1 with portions broken away;
FIGURE 4 is an enlarged, fragmentary, sectional view through 44 of FIGURE 1 showing the internal construction of the shaking apparatus.
The shaking apparatus includes a cylindrical base shell 1 having end flanges 2. The upper flange of the base shell 1 supports a plurality of upright springs 3 which are held by end clips 4 and bolts 5. The upper ends of the springs 3 are attached by additional end clips 4 and bolts 5 to channel brackets'6 Welded to the underside of a base plate 7. The base plate is circular and substantially larger than the base shell 1.
Fitted centrally in the base plate 7 is a cylindrical motor shell 8 which extends downwardly therefrom. Radial gussets 9 extend outwardly from the motor shell 8 and are welded to the underside of the base plate 7.
The motor shell 8 is provided with internal mounting flanges 10 and 11 which support a motor 12. Suitable clamp segments 13 interlock the motor with the upper mounting flange 11. The segments 13 are held in place by bolts 14. The extremities of the motor shaft carry upper and lower eccentric weights 15 and 16 so that on rotation of the motor 12 the base plate 7 is vibrated or shaken, as more fully set forth in the hereinbefore mentioned Meinzer patent.
Adjacent its periphery the base plate 7 may be provided with a short marginal skirt 17 and forms radially outwardly of the skirt a marginal flange 18. The base plate is adapted to support a series of cylindrical sections or shells 19, each having at its axial extremities radially outwardly extending flanges 20.
Fitted between the base plate 7 and the lower flange of the lowermost shell 19 is a mounting ring 21. mounting ring is provided with a radial or annular tonguev 22 which projects between the flanges 18 and 21). Each tongue 22 receives a seal ring 23 formed of rubber or other elastomer. The seal ring is normally U-shaped in cross section forming radially inwardly directed lips 24 fitted over the upper and lower sides of the corresponding radial tongue 22. The lips 24 are joined normally by a relatively thick cross section 25.
The lowermost seal ring 23 rests on the flange 18, and the bottom flange 20 of the lowermost shell 19 rests on the upper side thereof, as shown best in FIGURE 4. Similarly, the succeeding seal rings 23 rest on the upper flange of the lower shell and in turn support the lower flange of the upper shell.
The series of shells 19 are secured together by means of a series of clamp rings 26. Each clamp ring is essentially E-shaped in cross section and includes parallel flanges 27 which overlie the flanges 20 or the lowermost flange 20 and flange 18.
Each clamp ring 26 includes an annular displacement rib 28 between the flanges 27 which, when the clamp ring is constricted, is forced against the cross portion of the corresponding seal ring to compress the seal ring radially, thereby to displace the material of the seal ring axially so as to force the flanges 18 and 20 against the flanges 27. Each clamp ring is provided with one or more tie bolt units 29, as shown in FIGURE 1. The clamp ring is more fully described in the copending application of Howard W. Wright, IL, et al., entitled Clamping Means for Material Separators, filed March 28, 1960, Serial No. 17,973.
The uppermost shell 19 may receive a cover 30 having an inlet opening 31 in the center thereof.
Each of the cylindrical sections or shells 19 is provided with one or more discharge spouts 32. These are preferably arranged so that one vertical wall is substantially tangent to the corresponding section or shell. Each spout projects a suflicient distance to clear the clamp rings 26 and is provided with a short downwardly directed tube 33.
The radially inner portion of each mounting ring 21 within the boundaries of the shells 19 projects upwardly a short distance from the corresponding tongue 22. The lowermost mounting ring 21 supports a bottom discharge dome 34. The discharge dome is in the form of an inverted pan and its periphery is welded to the lowermost mounting ring at a level approximating or slightly below the bottom side of the corresponding discharge spent 32.
Each mounting ring 21 interposed between the intermediate sections or shells 19 supports the periphery of a circular screen 35. The periphery of the screen 35 is referably covered by a binding ring 36, which may be spot welded through the screen to the corresponding mounting ring 21. An elastomer or plastic seal 37 may be disposed in the annular region of juncture between the screen 35, mounting ring 21, and binding ring 36 to form a seal to prevent granular material from working under the binding ring and causing excessive wear. The center of each screen is provided with a small opening which is bordered by inner binding rings 38.
The bottom discharge dome 34 provides a means for discharging the material which sifts through the lowermost screen 35. In order to improve the efliciency of the screens, it is desirable to direct material to the central regions thereof. Thus material is supplied to the uppermost screen through the central opening provided by the inlet 31. Similarly, under each screen except the bottom one there is provided a discharge pan 39 which slopes downwardly towards its center and is provided with a central opening 49. The outer periphery of each discharge pan 39 is welded to the corresponding cylindrical Each section or shell 19 immediately below the upper flange thereof.
The central opening 40 of each discharge pan 39 is bridged by a spider or frame 41 which supports an up wardly directed post 42. Each post projects above the corresponding screen and is provided with washers 43 and nuts 44 so that the central portion of the screen may be drawn downwardly into a shallow cone. A similar post 42 projects upwardly from the center of the bottom discharge dome 34. The upper ends of the posts are preferably protected by caps 45 formed of rubber or other elastomer.
Operation of the shaking apparatus is as follows:
When the motor 12 is operated, the base plate 7 and the structure supported thereon oscillates and vibrates in a manner to cause material discharged on the screens to work gradually from the centers to the peripheries thereof, the finer particles falling through the screens and the coarser particles being retained thereon. The several spouts 32 carry off the material which has been classified by the series of screens. The nature of thevibration imparted by the motor 2 is more fully brought out in the aforementioned Meinzer patent.
It is highly desirable in installing the shaking apparatus that the spouts 32 be adjustable circumferentially so that each spout may discharge directly into any suitable conduit positioned therebelow. By reason of the arrangement of the base plate 7 and lowermost clamp ring 26, the lowermost cylindrical shell 19, and indeed all of the cylindrical shells 19, may be adjusted circumferentially a full 360. That is, any of the spouts 32 may be moved in either direction, as indicated by the arrows in FIGURES 2 and 3, merely by loosening the clamp rings 26, and thereafter the spouts may be locked in position by tightening the clamp rings.
While a particular embodiment of this invention has been shown and described, it is not intended to limit the same to the exact details of the construction set forth, and
it embraces such changes, modification, and equivalentsof the parts and their formation and arrangement as come within the purview of the appended claims.
