Definitions
- the subject invention relates to a device for supporting a present in a plant for paper production screen belt or felt belt or the paper web produced in the plant with a rotatably mounted support roller or the like.
- plants for paper production are at least one screen belt and at least one in the direction of movement of this subsequent felt belt, which two belts are moved in the system at high speeds.
- a pulp is sprayed.
- the liquid contained in the pulp is discharged through the wire, in particular sucked.
- the paper strip produced in this way is subsequently transferred to the felt belt, on which it is dried. Then the paper tape is released from the felt and processed further, in particular further dried and rolled.
- the screen belts, felt belts and paper belts in such paper-making installations have widths of up to 12 m, which are moved at speeds of about 30 m / sec along the installation.
- the sieve belts and felt belts present in the systems and the paper belts can be guided during their movement in the system via support rollers which extend over the entire width of the system and which are mounted at both ends. Due to the large length of the support rollers and due to the fact that the bands abut against these support rollers with high pressure, they must be formed with large diameters, whereby a high design effort is required. However, if suction means are associated with the wire belt or the felt belt, however, such back-up rollers can not be used because the space therebetween, through which the suction channel is defined, is so small relative to the area exposed to the suction action in that as a result no suction effect corresponding to the requirements is achieved.
- the objective of the present invention is therefore to provide a device for supporting the at least one screen belt, the at least one felt or the paper tape in a plant for paper production, by which the known support roller adhering disadvantages are avoided.
- This is inventively achieved in that the at least one support roller or the like. stored in a ply shell and on the side facing away from the wire, the felt belt or the paper tape side with a flowable medium, namely a liquid or a gas, can be acted upon, whereby it is held opposite the bearing surface at a distance.
- At least one channel for the supply of the flowable medium opens in the bearing shell.
- the at least one channel for the supply of the flowable medium may be formed with a nozzle-like constriction and may be provided in the bearing shell at least one mouth for the flowable medium with a widened region, in particular with a dome or with a slot formed.
- a valve in particular a check valve, are located in the at least one supply channel for the medium.
- the at least one support roller can also be acted upon by a flowable medium on its end faces.
- the at least one support roller or the like is preferably. At least partially overlapped by a cover, which in the acted upon by medium position of the at least one support roller or the like. is surmounted by this. It can further seen in the axial direction on both sides of the at least one support roller or the like. in each case a cover may be provided.
- a plurality of support rollers, support rollers or support balls is provided, which are mounted in at least one bearing shell and which are in the direction of movement of the wire, the felt or the paper tape side by side and possibly also one behind the other.
- further support rollers or the like on both sides of the screen belt, the felt belt or the paper tape. be provided, or the like between two juxtaposed support rollers.
- Suction channels are located, which are connected to a suction device.
- a felt belt further preferably located on the two sides of the felt belt rollers or the like., Which extend transversely to the felt belt, offset in the longitudinal direction of the felt belt against each other, wherein a arranged on one side of the support roller od .dgl. in the arranged between two on the other side support rollers or the like. protruding space, whereby the felt belt between the opposing support rollers or the like. is moved in a wave-like course.
- the felt belt is assigned an injection device.
- FIG. 1 is shown in a plant for paper production screen belt 1, which is supported by a support roller 2, wherein the support roller 2 is mounted in a bearing shell 3.
- the bearing shell 3 is formed with an approximately semi-cylindrical bearing surface and with end-side planar end faces.
- the bearing shell 3 with three channels 4 for the supply of a flowable medium, such as water or compressed air, formed, which open into the bearing surface.
- the end faces are formed with orifices, which a flowable medium is supplied.
- the supply channels 4 are each formed at their mouths 5 ends facing with a taper 6, through which the entry of impurities in the channels 4 is prevented.
- the mouths 5 of the channels 4 are each formed with an extension.
- check valves are provided in each of the supply channels.
- the support roller 2 By applying the support roller 2 with a medium, it is raised in the bearing shell 3 in the direction of the arrow A, whereby it is held opposite the bearing surface as well as with respect to the end faces at a distance, so that they can be rotated almost smoothly in the bearing shell 3.
- the support roller 2 can be used in the same way as a support for a felt belt or for the paper tape produced in the plant. Due to the fact that the support roller 2 is mounted over its entire length in the bearing shell 3, it can regardless of their length with a relatively small Diameter may be formed, without affecting their ability to function is reduced. It is to be noted that the back-up roll 2 may extend across the entire width of the wire belt 1, the felt belt or the paper belt, or that a plurality of coaxial back-up rollers or other support elements may be provided across the width of the belt.
- FIG.2 a second embodiment of a device according to the invention is shown, in which the support roller 2 is formed with laterally arranged covers 7, which are bent in the upper region to the support roller 2, whereby a lifting of the support roller 2 is limited beyond a predetermined extent.
- the covers 7 are fastened here by means of screws 8 to the bearing shell 3.
- the bearing shell 3 is fixed to a plate-shaped carrier 10, which is penetrated by the three supply channels 4 and in the lower region, a recess 11 is located, from which the three supply channels 4 depart.
- a support roller 2 is explained as a crushing roller in a plant for paper production. Crushing rolls are used to straighten the paper strip 13 in a sheeter. In this case, the paper tape 13 is guided over a first deflecting roller 14, then over the supporting roller 2 and further over a second deflecting roller 15. In order to adjust the extent of the bends of the paper tape 13, the carrier 10 is height adjustable.
- FIG.4 three juxtaposed support rollers 2 are shown in the direction of movement of the wire belt 1 and the felt belt, between which suction channels 16 are located.
- the carriers 10 are fastened by means of screws 10a to a support 17 which is formed with suction channels 16a connected to a suction device.
- the screen belt 1 and the felt belt between the support rollers 2 are subjected to a suction force.
- a support device is therefore advantageous because it requires only low drive power for the movement of the at least one screen belt or the at least one felt belt, since the wear of the support elements on the one hand and the screen belt or the felt belt is low and since there is sufficient space between the support elements for suction channels, in order to be able to apply suction forces corresponding to the requirements on the screen belt or on the felt belt.
- FIG.4 is a further development of the device according to FIG.4 represented, in which on both sides of a felt belt 1a a plurality of such support rollers 2 are provided, between which are connected to a suction suction channels 16.
- each of the support rollers 2 located on one side of the felt belt 1a are offset in the longitudinal direction of the felt belt 1a from the support rollers 2 located on the other side of the felt belt 1a and protrude into the backup rollers 2 provided between the other side of the felt belt 1a A spaces, whereby the felt belt 1a is moved in a wave-like course.
- the support rollers 2 located on the two sides of the felt 1 a are mutually adjustable, whereby the wave-shaped course of the felt 1 a is adjustable.
- a spray tube 9 which is oriented transversely to the movement path of the felt belt 1a, is provided, through which the felt belt 1a is subjected to a cleaning liquid 9a.
