Abstract: In a belt press of the type used to dewater heavy slurries, an improved belt drive system is provided. The upper belt is driven by at least two rollers, one of which is situated in the dewatering section wherein the upper and lower belts are squeezed and traveling together. The improved drive arrangement provides a more uniformly increasing tension in the belt as it passes through the dewatering section than in such presses heretofore. Further because the lower belt is at least partially driven by its frictional engagement with the upper belt, through the sandwiched slurry, the synchronization of the belt speeds is improved. Further improved control of the belt press performance is provided by means for sensing the speeds of the belts and responsive means for regulating the belt tensioning systems accordingly.

Abstract: In a wet press for dewatering a web of material, for instance a paper web, a contact pressure device is provided which presses against a rotating roll and exerts an incrementally increasing pressure in the direction of travel of the paper web. The contact pressure device comprises only a single pressure element arranged in the direction of travel of the paper web.

The increasing contact pressure is attained by arranging the pressure element unsymmetrically in relation to the pressure chamber. The effective pressure cross-sectional areas of pressure pockets arranged sequentially in the direction of web travel can additionally be reduced in the direction of web travel or the cross-sections of the associated bores can be increased.

Abstract: The belt press unit of a paper machine includes an elastic tubular press belt which passes around the circumference of and is spaced from the surface of a hollow, annular supporting body. A press shoe in the supporting body presses outwardly and urges the press belt against an opposing surface on a mating roller for defining a press nip.

A torsionally rigid beam extends through and is attached at two axially spaced locations along the hollow of the annular supporting body. At least one of the guide ledges is supported to the beam, whereby radial deflection of the supporting body does not result in radial deflection of the beam and thus does not cause radial shifting of the guide ledge. The beam is axially displaceable with respect to the supporting body.

A radially non-displaceable press shoe is supported on the support body and faces toward a counter-roll to define a press nip between them. The outwardly facing surface of the press shoe is concave in the circumferential direction of the support body. The amount of pressure in the hydraulic supporting means determines the press force which prevails in the press zone.

The harvested leaves of the aloe vera plants are positioned between a pair of endless moving belts for passing by a plurality of crushing rollers arranged in a desired pattern. The rollers first crush the core of the leaf to enable the gel to flow internally while a second set of rollers extrudes the gel from the leaf. The crushed leaf and extruded gel is then deposited on a drain grate to enable gravity flow separation of the gel from the crushed leaves. The drainage grate is sloped in order that the leaves will slowly move across the drain grate to enable separation of the gel while removing the leaf from the gel collection area prior to the flowing of the contaminate aloin from the leaf.

Abstract: In a wet press for dewatering a web of material, for instance a web of paper, a contact pressure device presses against a rotating roll and exerts a pressure which increases in the travel direction of the web of paper. For this purpose, several rows of contact pressure elements are arranged sequentially in the travel direction of the web of paper. In each row the contact pressure elements are arranged side by side transversely to the travel direction of the web of paper. In order to circumvent a differential dewatering at the location of the contact pressure elements and at the gaps between the contact pressure elements of a row, the contact pressure elements of successive rows are shifted or staggered in relation to one another transversely to the web of material such that they mutually overlap. This prevents the arisal of strips in the paper being processed.

Abstract: In a belt pressing unit, which preferably serves as wet press of a paper machine, an elastic tubular press belt travels around a supporting body and, together with a back roll, forms an extended press zone. Beyond the press zone along the path of the press belt, liquid is fed to the inner side of the press belt in order to cool the press belt. This liquid is permitted to travel, together with the press belt, around the supporting body. Most of the liquid is then removed from the press belt, preferably at a position in front of the press zone. The liquid may then be cooled and fed back to the press belt. In addition, liquid may also be fed to the inner side of the press belt where the press belt enters the press zone, for cooling and lubricating a pressing surface of a press shoe which presses the press belt toward the back roll.

Abstract: The invention relates to a method and means for removing water from a web in a press of a papermaking machine. The web to be dried is passed between press felts through a press nip formed between press rolls. A resilient mat or the like, which is in contact with one of the press felts, is also passed through the press nip. In order to produce a hydraulic counterpressure at the nip, a wire is passed between the resilient mat and one of the press rolls and water is sprayed on the wire immediately before the press nip for producing a water cushion in the section of the wire lying between the press roll and the resilient mat. The wire is in this case formed so that water cannot move in the longitudinal or vertical direction of the wire.

A pair of opposed filter belts (22, 23 or 142, 144) are trained about the primary roll and means are provided to feed the wet mixture between the belts to carry the mixture successively through the nips between the primary roll and the pressure rolls. The mixture is initially subjected in the first nip to a relatively gradual rate of increase in pressure and in subsequent nips is subjected to progressively steeper rates of increase in pressure adapted to the different flow behavior of the mixture caused by the increasing solids content of the mixture.

Abstract: Slurry is fed (at 52) onto the upper run 46 of endless filter belt 48 and is dewatered by intermittently-operating means e.g. vacuum box 54, press assembly 56 and/or gravity box 66. The belt 48 is guided by a number of transverse guide bars 44, 76, 82, 84, 86, 88 and is progressed intermittently by a displaceable guide bar 74 whose forward movement extends the upper run 46. The bar 74 is coupled (e.g. by cables 106) with a slack-compensating guide bar 104 cooperating with the return run of the belt 48 and unidirectional means (e.g. arrester guide 94 and arrester roller 98) located therebetween allows movement of belt 48 only in the forward direction (arrow 114).Because this belt filter incorporates well supported guide bars instead of conventional rollers, the belt 48 can be much wider than has hitherto been practicable and the overall length of the filter may be correspondingly reduced, further obviating guiding problems.

Abstract: The liquid content of sugar cane bagasse is reduced by a low pressure process having a substantially longer duration than the duration of prior art high pressure liquid removal processes. For this purpose the liquid containing bagasse, as it emerges from a diffuser, is exposed to a relatively slowly increasing yet low pressure as compared to prior art high pressures, whereby the bagasse travels with a substantially constant speed sequentially through a dewatering zone, wherein a further compaction takes place, a preliminary squeeze-out zone and a final squeeze-out zone. During the preliminary squeeze-out the pressure above an open surface area or section without a sieve or screen is about 0.2 kg/cm.sup.2. During the final squeeze-out the pressure (p) is about p/0.6D>0.003, wherein D is the diameter, in mm, of a squeeze-out roller. The pressing duration t in seconds is also related to the squeeze-out roller diameter D such that D:t is smaller than a constant value K 16.
