- An apparatus for producing a voluminous tissue web is already described in US Pat. No.
- the fibrous web in the forming zone is dewatered through a forming wire by means of applied centrifugal forces to a solids content of about 12%, whereupon the fibrous web is further dehydrated by vacuum to a solids content of about 23% and mechanically from a solids content of about 23% to about 40%.
- the fibrous web is highly compressed, which adversely affects their thickness, volume and water absorbency.
- a dry content limit of 23% more or less represents the maximum dry content value in the dry content vacuum curve that can be achieved by dewatering a tissue web on a wet felt.
- the provision of a larger vacuum capacity is not energy efficient.
- the invention has for its object to provide an improved device of the type mentioned above, with the lowest possible energy consumption while avoiding unwanted excessive compression of the fibrous web reach a higher dry content of the fibrous web immediately after the belt press and thus in particular also for the production a voluminous tissue web is used.
- the fluid loading means of the device comprise a blowing device, which is arranged and designed so that the fluid flows from the curved surface of the counter element of the belt press to the press belt of the belt press.
- the fluid thus flows in the direction of the centrifugal force acting on the fibrous web as a result of the curved surface of the counter element.
- the blowing device may in particular comprise a blow box assigned to the counter element of the belt press.
- the fibrous web is guided lying between the carrier tape and the press belt lying through the press nip of the belt press.
- the fibrous web guided together with the carrier belt through the press nip of the belt press contacts the press belt and the carrier belt the counter element of the belt press.
- the fluid acting on at least a portion of the press nips of the belt press advantageously contains hot, moist air and / or steam.
- the device is designed to form a structured fibrous web and as
- Carrier tape provided a structured band.
- a corresponding device is particularly suitable for producing a voluminous tissue web.
- the fibrous web is preferably passed together with the carrier tape from a forming zone of the device to the belt press and through it.
- the device may in particular comprise a forming zone in which the fibrous web is formed on the preferably structured carrier tape.
- the belt press is also preferably arranged downstream of a drying zone, which is fed to the fibrous web together with the carrier tape.
- a drying zone expediently has a drying cylinder, in particular Yankee cylinder, and preferably a hood associated with the drying cylinder.
- the drying cylinder for forming a further pressing zone associated with a counter-element which advantageously comprises a shoe pressing element, in particular shoe press roll, a counter-element with associated suction device, in particular suction roll, or a conventional press roll.
- the fibrous web is transferred in the region of the further press zone of the carrier tape to the drying cylinder and continued on this.
- the press belt of the belt press is designed for the highest possible tensile stress and preferably for a tensile stress> 30 kN / m.
- a tensile stress in the range from about 10 kN / m to about 30 kN / m acts on the press belt of the belt press.
- the surface of the press belt of the belt press advantageously has a fiber structure with fibers having a fineness ⁇ 44 dtex, in particular ⁇ 17 dtex and preferably ⁇ 1 dtex.
- the permeable press belt of the belt press preferably has a permeability, in particular air permeability, of more than 20 cfm, in particular more than 60 cfm and preferably more than 100 cfm.
- the press belt of the belt press has a thickness ⁇ 4 mm, in particular ⁇ 2.8 mm and preferably ⁇ 1, 9 mm.
- the radius of curvature of the curved surface of the counter element of the counter roll of the belt press is advantageously ⁇ 0.6 m and is preferably in the range of 0.35 m. If, for example, a blow roll is provided as the counter element of the belt press, its diameter is correspondingly advantageously ⁇ 1.2 m and is preferably in the range of 0.7 m. With a correspondingly small radius of curvature or diameter higher centrifugal forces are achieved, with a correspondingly higher drainage is achieved.
- the device according to the invention is thus particularly suitable for producing a structured, voluminous tissue web, wherein the fibrous web produced can in particular have more than 70% non-pressed fibers and a thickness which is in particular twice or more than twice as large and correspondingly a higher volume and a corresponding one has higher water absorbency than the aforementioned known devices.
- the device according to the invention can in particular also be operated at higher speeds.
- the investment and energy costs are lower than in the known devices such as TAD (Through Air Drying) machines or crescent formers with a shoe press.
- the belt press according to the invention can be arranged downstream of a drying zone with a drying cylinder, in particular a Yankee cylinder.
- a structured fibrous web can be dewatered using the belt press using a very low pressing pressure of, for example, about 0.85 bar and with a very long press nip of, for example, 0.9 m, which is about 15 times longer than in a conventional press, for example a press nip with a length of 60 mm and is operated at, for example, 35 bar.
- a dry content in the range of 12 to 30% and more can be achieved.
- the fibrous web of the drying zone is supplied with a dry content> 30%, so that the fibrous web can be further dried in this drying cylinder, in particular Yankee cylinder with associated drying hood, comprehensive drying zone.
- the device according to the invention can be obtained in a simple manner by a corresponding conversion, for example, of a conventional paper machine with a shoe press.
- hot, dry air, steam or moist, hot air can be used as the fluid.
- the fluid can serve for heating the fibrous web and / or for receiving water from the fibrous web.
- the fluid may be at least partially removed from the hood exhaust air of the hood associated with the drying cylinder of the drying zone, whereby the energy consumption is further reduced accordingly.
- the fibrous web is preferably on the structured
- the press formed with the drying cylinder of the drying zone only the bumps of the structured strip are pressed, leaving 70 to 80% of the fibers of the fibrous web completely unpressed, resulting in an overall voluminous fibrous web of greater thickness and higher specific volume.
- the fibrous web can also be formed, for example, in a twin-wire former or another type of former.
- the formed fibrous web can also be transferred by means of a pick-up shoe or the like to the structured carrier tape.
- the high-tension permeable press belt of the belt press may be, in particular, a high-tension belt such as a reinforced felt with reinforced seam or an endless spiral-woven fabric with a needled fiber pile fiber (Feited Belt).
- the press belt should have even at higher temperatures only limited elongation, especially since the fluid is hot and in the paper machine in question usually only limited space is available.
- the reinforced structure of the press belt may have a woven or a non-woven structure, depending on the required conditions of tension and temperature.
- the material used can also contain components of a biko type (components with bico character).
- Biko fibers bis-component fibers themselves are known in the art. It is advantageous to use such biko fibers and / or yarns for the production of the press belt both for the support structure and for the design of the at least paper-contacting surface of the press belt.
- Biko fibers or yarns comprise two material components. The first material component forms the core of the fibers or yarns and the second material component encloses or encases the first material component.
- a band structure of the press belt without fibers is also conceivable, which also facilitates conditioning and avoids rapid contamination of the structure.
- the surface structure, in particular the contact side of the press belt for example when casting the tape and / or by melting Plastics or other materials and / or by material-removing processes, for example, be produced by laser or water jet technology.
- the advantage here lies in the manufacturability of an almost arbitrarily configurable surface structure.
- the permeability can be generated, for example, during casting of the strip and / or by material-removing processes, for example by laser or water jet technology.
- the pressing pressure p generated in the press nip of the belt press results from the quotient of the tension T and the radius of curvature of the counter element of the belt press or the radius R of a blowing roller provided as a counter element.
- a pressure of 0.85 bar acting on the sandwich of fibrous web and carrier tape results.
- the dewatering in the belt press thus takes place starting from the curved surface of the counter element to the press belt through first the porous carrier belt and then through the fibrous web.
- the particular structured permeable carrier tape runs approximately dry on the side of the counter element through the press nip the Belt press, which results in a much lower rewet compared to a felt on the side of the mating element.
- the fibrous web remains on the structured carrier belt and not on the felted press belt, since the fibers of the fibrous web lie in the depressions of the structured carrier belt.
- the dry content achievable with such a band press is at least 7% higher than without a band press and with a carrier band having a normal felt configuration and 12% higher than without Belt press and with a carrier tape with the textured tape configuration.
- the press nip of the belt press can in particular have a length of> 700 mm.
- the achievable dry content is further increased.
- the press formed with the drying cylinder serves only for the further transport of the fibrous web and not the increase of the dry content.
- a dry content of at least 30% should be achieved at the outlet of the belt press, which corresponds to the dry content immediately after the press formed with the drying cylinder of the drying zone.
