Description
This invention relates to compression rollers for dehydration equipment, in particular double-belt presses, on which is guided an upper endless sieve-belt or wire-cloth on parallelly arranged rollers, a similar set of rollers being located underneath on ~hich, in turn, runs a lower endless wire cloth, the suspension to be dehydrated being introduced into the space between the wire-cloths, and the groups of rollers being divided in~o wedging, registering, pre-pressing and main-compressing roller sections.
Compression rollers are used to feed the material already partially pre-dehydrated in the individual roller sections of the dehydration equipment of the invention to a main dehydration stage. AS already mentioned, such machinery is known as double belt presses. Similar equipment is shown in Austrian Patent No. 313,044 which issued on January 25, 1974 to Johann Sbaschnigg. This equipment also comprises a set of rollers divided into wedging, registering, pre-pressing an~ main pressing sections.
While such equipment affords very high efficiency and is indeed very compact, increasing its output generally is implemented by enlarging the belt width so as to feed a correspondingly larger amount into the machine at the intake.
This enlarging method, simple per se, has limitations however because such equipment cannot be made arbitrarily large. This limitation is set not only by spatial size, but above all by the mechanical strength of the individual compression rollers. As long as the suspension holds appreciable humidity and the compression is not required to be high, rollers of relatively small diameters will suffice. The areal compression is gradually increased by the wedge arrangement of the rollers until the suspension comes to the end of the wet and registering sections.
In view of the progressive dehydration from one pair of rollers to the next in the following pre-compresslon sectlon, the compresslon so lncreases that already serious problems relating to the mechanical strength of these compres-slon rollers may occur. This requlres selectlng an already somewhat larger roller dlameter than for the previcus roller at the registerlng sectlon ln order to withstand the compressive stresses. What thls means most of all is that for relatlvely wlde rollers, they may so flex that the deslred compresslon no longer can be malntalned, at least ln the central reglon of the wlre cloth. Concelvably such compresslon rollers mlght be addltlonally supported by other supportlng rollers above or below them or by slmilar means. Such a step however may be undeslrable because of the greater bu!k of the machlne, and slgnlfl- `
cantly, these support rollers also mlght damage the compresslon rollers wlth adverse scorlng or groovlng for the wlre cloth. The blggest draw-back furthermore ls that the speclflc compresslon depends upon the roller dlameter and can be lncreased only by decreaslng thls dlameter.
But a decrease ln dlameter agaln ls lmposslble on ground of mechanl-cal strength because the rollers wlll flex above a glven compresslon llmlt and therefore will no longer achleve the deslred dehydratlon effect .
The lnventlon addresses the task of creatlng compresslon rollers for dehydration equipment, ln partlcular for double belt presses of the prevlously clted type, whlch permlt signlflcant wldenlng of the equlp-ment wlthout thereby causlng roller flexure and preventlng a loss ln compresslon at least ln the central reglon of the wire cloth. Thls ob- ' ject is achieved by the invention by deslgning the compresslon rollers in the pre-compression section in multi-pieces across the width of the equlpment and by alternatingly mountlng them in an offset manner for-ward and backward in the direction of motion of the wire cloth, the roller ends pro jecting into the region of the next one in an overlapping manner.
This design of the compression rollers permits so extending the machine width that its output can be signifi-cantly increased. This offers the advantage that the same compression also is applied practically at the center of the wire cloth to the suspension and that flexure of the rollers no longer is possible. Furthermore it is less expensive to make individual rollers and storage of spare parts thus causes no difficulties.
In summary of the above, therefore, the present invention provides in dehydrating equipment, in particular double belt presses, in which an upper endless sieve belt is guided by means of parallelly supported rollers, with parallelly supported rollers being similarly arran~ed below and on which a lower endless sieve belt is guided, the suspension to be dehydrated being introduced between the sieve belts, the sets of rollers being divided into a wedge section, a registering section, a pre-compression section and a main compression section, the improvement comprising that the individual compression rollers in the pre-compression section are composed of several pieces extending across the equipment and, when viewed in the direction of motion of the sieve belts, are alternately offset backwardly or forwardly, the ends of the rollers penetrating the region of adjacent rollers in overlapping fashion.
The invention will be further illustrated by reference to the accompanying drawings, in which:
~ _ 3 _ B
1(~83883 Figure 1 is an elevation of a double belt press, Figure 2 is a top view of the rollers and ~ 'igure 3 is a view of the compression rollers bearing.
Figure 1 is a side view of a dehydrating machine.
The equipment support is composed of a structure 1, ., plus a frame mounted transversely to the longitudinal machine axis and somewhat in the shape of gallows and to which are mounted the upper girder 2 in a lengthwise manner and the lower girder 3. The individual rollers 8, 9, and 11 are mounted to these two girders 2 and 3.
An upper wire cloth 4 is guided around the upper rollers and in similar manner a lower wire cloth 5 around the lower ones. The machine is divided into individual sections, the wet part or wedging section A at the equipment intake subjecting the suspension to pre-dehydration and prefer-ably comprising the suction boxes 7 in lieu of rollers.
After the wedging section A, the cake 6 of material so created is fed to r~
the registerlng sectlon B composed of a number of palrs of rolle~s wlth gradually decreaslng vertlcal axlal separatlon. The pre-dehydrated materlal is further squeezed ln thls registering sectlon and fed to the next roller sectlon denoted as a pre-compression sec-tion C, whlch preferably ls of ascendlng deslgn. The roller arrange-ments of the inventlon are located ln this pre-compres sion sectlon C;
they wlll be dlscussed comprehenslvely below. Lastly, the maln com-presslon sectlon D is mounted at the end of the equlpment: lt exerts hlgh pressure on the materlal to be dehydrated and removes any re-sldual molsture from the cake of materlal.
As already mentioned, the wedglng sectlon A ls composed of lndlvldual suctlon boxes 7 taklng ln molsture through the wlre cloths 4 and 5 and exhaustlng lt through proper malns. The reglsterlng rollers 8 are mounted ln the reglsterlng sectlon ~, the vertlcal sepa-ratlon between the roller axes decreaslng from one palr of rollers to the next, whereby the materlal to be dehydrated assumes the shape of a wedge. Sturdy, double T-shaped supports 10 are mounted to the glrders 2 and 3 ln the pre-compression sectlon C and e~tend across the entlre wldth of the equlpment. Agaln, an arrangement of upper and lower rollers belng the case, one such support 10 must be flxed ln each glrder 2 and 3. Vlewed ln the dlrectlon of the wlre cloths, the bearlng rollers 21 are mounted ln the support 10 and provlde bearlngs for the compresslon rollers 9. The compresslon rollers 9 no longer are composed of rollers whlch are contlnuous from slde to slde, rather they are composed of several pleces which, in order to ellml-nate pleats ln the wire cloth, are made forwardly and backwardly offset wlth respect to each other, 1. e . ln an overlapplng manner.
.~ , ~ . . -. .
The dlameters of the compresslon rollers 9 are less than those of the rollers 8 of ~he registering section 8 in order to lncrease the speclflc compres slon .
The main compressing section D now is composed of an essen-tially larger pair of rollers 11 which, hawever, need not be iurther discussed. Using a lever 17, the upper roller of the maln compress-lon rollers 11 19 50 moved wlth respect to a polnt of rotatlon 18 by means of a pressure-bellows 16 that the compresslon may be ad~usted as needed. Also, a slmllar eccentrlc lever 14 wlth an axls of rota-tlon 19 ls mounted to the lower slde of the pre-compresslon sectlon C, whlch ln turn can vary the compresslon actlng on the lower part of the compresslon rollers 9. The wlre cloths 4 and 5 are deslgned as endless belts and pass over the rollers mounted ln the lndlvldual sectlons. The tenslonlng rollers 12 and gulde rollers 13 are further provlded for tenslonlng the wlre cloths. The arrow P lndlcates the dlrectlon of motlon of the wLre cloth.
Flgure 2 is a top vlew showing the arrangement of the com-presslon rollers 9. They are mounted on the support 10 extending across the entire wldth of the equlpment. The Flgure lltustratlvely shows only three compresslon rollers 9, but qulte conceivably thelr number may be lncreased dependlng on thelr length and on the wldth of the partlcular machlne. The compresslon rollers 9 are so mounted by means of the bearlng rollers 21 on the support 10 that when vlewed ln the dlrectlon of motlon of the wlre cloth (arrow P), one wlll be offset backwardly, or the other forwardly. It should be borne ln mlnd in thls regard that one end of a roller does not begln lmmedlately where the other ceases, but rather that there ls a given ~ .... . .
overlap U of the two ends. Thls overlap U corresponds to the length of a roller radius. Thls ensures there wlll be no unevenness ln dehydratlon at the lmpact points of the rollers. The ends 25 furthermore are provlded wlth a bevel 22 deslgned as a convex sur-face. Beyond thls bevel there are the bearing pins 23, in conven-tlonal manner, which ln turn rest ln the bearlngs 21.
Figure 3 shows a sectlon correspondlng to the arrows of the compresslon roller arrangement shown ln Flgure 2. The deslgn and the arrangement of the two T-shaped supports 10 are readlly apparent, the support bearings 21 ~olnlng the chords faclng them. Any assem-bly lnaccuracles may be compensated for uslng the levellng pleces 24. Naturally, the supports 10 are so flxed ln the glrder that flne adJustment of the spaclng between the roller palrs may be achleved.
Here agaln the arrow P lndlcates the dlrectlon of motlon of the wlre cloth. The transverse dralns 20 advantageously are provlded to draln water ln order to ellmlnate reabsorptlon of the molsture.
Thls deslgn of the compresslon rollers 9, whlch no longer are one lntegral plece but rather are multl-plece, achleves the feaslblllty of decreaslng the dlameter of the compresslon rollers 9, for the pur-pose of lncreaslng the speclflc compresslon, ln a manner such that no flexure occurs. If, for example, the rollers were of one lntegral plece, there lnevltably would be hlgher dehydratlon ln the vlclnlty of the bearlng locatlons and lnadequate dehydratlon at the center of the wlre cloth path. Thls cannot happen ln the compresslon rollers of the lnventlon because proper sizing prevents flexure of the support 10 and the relatlvely short compresslon rollers 9 can wlthstand the load wlthout deformatlon. It follows from thls deslgn that lt ls '. ' ' . '' ' ' . '' ~ ~ ' - :
r~ , posslble to make dehydratlon equlpment of greater wldths and that, furthermore, the specific compresslon applied to the materlal to be dehydrated also can be further increased. In thls manner lt ls pos-slble in a slmple fashlon to further lmprove the equlpment efflclency.
It wlll be obvlous to those skllled in the art that many modifi-catlons may be made wlthin the scope of the present lnventlon wlthout departing from the spirit thereof, and the invention lncludes all such modlflcatlons .
