Definitions
- the invention relates to a heated cylinder for heating a paper, cardboard, tissue or other fibrous web in a machine for producing and / or finishing the fibrous web with a cylinder jacket which is at least partially acted upon from the inside by means of a hot fluid and at least one includes inner and an outer cladding layer.
- Such a heated cylinder is known from DE 102 60 509.2.
- tensile stresses that arise because the inner area of the cylinder expands more than the outer area are minimized by the fact that the cylinder jacket consists of at least two jacket layers and the material of the outer jacket layer at an assembly temperature that is below the average operating temperature lies, a larger coefficient of thermal expansion and at a mounting temperature that is above the average operating temperature, a smaller coefficient of thermal expansion than the material of the inner cladding layer.
- Another measure is that the layer thickness of the outer cladding layer is less than that of the inner cladding layer.
- a dryer for drying a fibrous web is known from EP 0 559 628 B1, in which a flow cylinder is used in connection with a blowing hood. This is provided with a nozzle arrangement, with the aid of which drying gas jets are applied to the outer surface of the web to be dried, while this is guided over a sector of approximately 270 ° or more around the heated cylinder.
- the jacket of the cylinder is with a system of Provide duct lines in which a coolant can be directed from a coolant source.
- the drying gas jets evaporate water in the web to the outside and remove it via the spaces in the blowing hood.
- this object is achieved in a heatable cylinder of the type mentioned at the outset in that the two jacket layers are separated from one another by a cavity into which the fluid can be introduced. Due to the double-shell design of the drying cylinder, the temperature gradient between the cylinder surface and the steam is reduced and kept low.
- the wall thickness of the outer cladding layer can be kept low by the invention; in particular, the loads on the outer wall of the cylinder can be kept low by supports against the core of the cylinder or by cross struts. Due to the possible small wall thickness of the outer jacket layer of the cylinder, the temperature gradient in this jacket layer is also kept low. By reducing the thermal resistance compared to conventional cylinders, the drying performance of the cylinder can be increased at the same vapor pressure by improving the heat flow through the outer jacket layer and increasing the temperature on the outer cylinder surface.
- the pressure in the two-shell solution according to the invention acts only in the annular cross section between the inside of the outer shell and the outside of the inner shell, which are fixed to one another by means of connecting elements.
- the outer shell is retained by the connecting elements due to the pressure that acts on the inner shell in the opposite direction and also reduces the load on the inner shell.
- the remaining load for both shells results from the pressure and the difference in the pressurized surfaces, which corresponds to the difference in their diameters.
- the shells can be made much thinner by reducing the load and, with the same load-bearing capacity, enable a reduction in their own weight and, thanks to the reduced wall thickness of the outer jacket, an improvement in heat transfer.
- the measure according to the invention proves to be particularly advantageous in the case of a dry arrangement in which the cylinder, as is known from EP 0 559 628 B1, is covered with a hood over a large, for example 270 ° area of its jacket surface.
- the hood is filled with a medium, in particular water, under an overpressure of 1 to 5 bar. Because the hood is stationary and does not enclose the entire circumference, a cyclic load acts on the surface of the jacket. A pressure load therefore acts on a point on the lateral surface of the cylinder as soon as the point moves into the area wrapped by the pressure hood. Relief takes place as soon as he leaves this area. The pressurization causes a high mechanical load, which also acts cyclically on the cylinder surface with every revolution. Conventional type drying cylinders could not withstand such a pressure load.
- the inner cladding layer is thicker in relation to the outer cladding layer.
- the outer shell is preferably thin-walled and has a wall thickness in the range between 5 and 15 mm, in particular between 8 and 15 mm. It is connected to the rigid core of the cylinder by means of webs. The vapor space is located between the thin outer shell and the core.
- the steam in the cavity between the two cladding layers advantageously has an overpressure between 2 and 13 bar.
- An advantageous measure consists in that a structure with ribs or lamellae which extend in the axial direction is applied to the inner surface of the outer cladding layer facing the cavity. This helps to keep the temperature gradient between the outer jacket surface of the drying cylinder and the cavity carrying a hot medium between the inner and the outer wall low.
- the condensate collects at the bottom of the ribbing. Even a small condensate film thickness would have a strong thermal insulation and increase the temperature gradient to the cylinder surface.
- the flank area of the ribs is not covered with condensate and is therefore in direct contact with the steam; it ensures a high heat flow. Due to the increased surface area of the outer shell of the cylinder as a result of the ribbing, the heat transfer is improved by increasing the contact area with the steam.
- its inner surface can be increased by a factor of 10 to 100. In other words, the surface of the rib, honeycomb or lattice structure is ten to one hundred times the inner surface of the outer cladding layer.
- At least the ribs or additionally the inside of the roll shell are made of copper or aluminum.
- the structures applied to the inside of the roll shell can also be made of steel or stainless steel or another metal or another metal alloy if the factor for increasing the surface area is chosen to be sufficiently large.
- the material used to improve the thermal conductivity is preferably the same as that of the cylinder jacket connected to the structures, in order to ensure that no stresses arise as a result of different thermal expansions.
- the outer cladding layer is made of a material with high thermal conductivity, i. H. with a high thermal conductivity.
- the outer jacket layer preferably consists of boiler steel. Steels with an austenitic structure are less suitable.
- the material from which the inner cladding layer is made does not have to meet any special requirements with regard to thermal conductivity; However, it is advantageous if the inner cladding layer has a high modulus of elasticity and at least the strength of an average structural steel.
- the advantages of the invention are that since the steam only spreads in channels, there is little mechanical stress. A high heat flow density is possible due to a reduced temperature gradient to the surface.
- the heated cylinder is suitable for high pressure loads from outside and for high temperature tensions. If the cylinder according to the invention is used with the same surface temperature as conventional drying cylinders, a steam with a lower saturated steam pressure can be used. When steam is used in a cogeneration system, it can expand to a lower pressure in the turbine, producing more electrical energy.
- the cylinder is connected via pipes between the inner and the outer jacket layer via rotary unions to a fixed steam supply or an evaporation and condensation water container.
- the inner cladding layer has the supporting function and serves as a rigid core, it absorbs the loads acting on the outer cladding layer.
- the inner and the outer jacket layer via pins, screws, rivets and the like. Like. Are connected.
- the lamellae are preferably arranged parallel to one another, in particular in the axial direction or also in the circumferential direction of the cylinder, but alternatively also crosswise, helically or in a honeycomb or lattice structure.
- a few lamellae form a helical spiral around the longitudinal axis of the cylinder.
- the slats have either a flat or a profiled surface. It is also advantageous if the lamellae widen towards the outer jacket shell.
- the surface of the structure on the inside of the outer circumferential cladding layer is reduced in the vicinity of the end face. This is achieved either by reducing the height of the fins, the honeycomb or the grid, or the distances between the fins or the walls of the honeycomb or the grid are greater in the edge area than in the middle of the outer cladding layer. By reducing the surface of the heat-transferring structure, overheating of the front edges of the jacket layer is avoided.
- the invention also relates to a heated cylinder for heating a paper, cardboard, tissue or other fibrous web in a machine for producing and / or finishing the fibrous web, which has only a single outer cylinder jacket.
- this is given high stability in that it is supported by struts in the interior of the cylinder.
- the struts are, for example, rods extending in the radial direction; however, support walls can also be provided which pass through the longitudinal axis.
- the struts or walls give the cylinder such stability that the jacket wall only has to have a small thickness. It consists of a good heat-conducting material which gives off the heat introduced into the interior of the cylinder via a fluid to the fibrous web guided over its outer jacket wall. This results in an increased energy yield compared to the prior art and a reduction in operating costs.
- FIG. 2 shows a longitudinal section through the cylinder according to FIG. 1,
- FIG. 3 is a partial perspective view of a second cylinder
- FIG. 4 shows a greatly enlarged detail from the jacket of the second cylinder in a sectional view along a line IV-IV in FIG. 3,
- Fig. 6 shows a cross section through a further cylinder.

- the cylinder 1 has in at least one of its journals 9, 10 an outer annular line 11 and an inner line 12. Instead of the single outer line 11, several outer lines can also be present.
- Hot steam flows into the cylinder 1 via the outer line 11 and is first passed along the end wall 3 and then between the outer shell-side wall of the inner shell 5 and the inner wall of the outer shell layer 6. In this case, heat is released from the steam via the jacket layer 6 to the fibrous web running between it and along the blowing hood. As a result, the steam cools down and partially condenses to water.
- the cooled steam and the condensate from the steam are passed between the end wall 4 of the inner shell 5 and then through a central line 13 in the axis 2.
- the line 13 merges into the line 12 in the journal 9.
- the lines 11, 12 are connected to a fixed steam supply or an evaporation and condensation water container via rotary unions (not shown here). Instead of leading both lines 11, 12 through the same journal 9, one of the two lines 11, 12 can alternatively also be passed through the other journal 10.
- a cylinder 14 is designed with two shells.
- An inner shell 15 mainly takes on the load-bearing function and serves as a rigid core which, among other things, also absorbs the loads of an outer, thin jacket layer 16.
- the connection between the inner shell 15 and the cladding layer 16 is preferably carried out via pins 17, which are either walled or made of solid material. These can have any cross-sectional shape and can be, for example, round, rectangular or hexagonal. The cross-sectional shape can also change over the pin length.
- the pins 17 are pushed through openings in the cladding layer 16 or in the inner shell 15 and are preferably connected to the cladding layer 16 and / or to the inner shell 15 by welding, in particular friction welding, or by gluing, screwing, soldering, clamping or other techniques.
- the pins 17 can also be made in two or more parts. Various methods such as screwing, gluing, clamping, welding or plastically deforming methods such as rivets come into consideration for the connection of the parts of the pins 17 to one another.
- the pins 17 can be prepared in the inner shell 15 Screw holes, punched holes or flame cuts into the outer shell with screw threads and connect or glue them to the inside of the cladding layer 16 by friction welding. If the pins 17 consist of two parts, the first part can be attached to the inside of the jacket layer by friction welding, for example, while the second pin part is pressed with the inner shell 15.
