Definitions
- the invention relates to a steam blow box unit with a steam blow box for applying steam to a passing material web, in particular paper or cardboard web. It also relates to a method for moving a steam blower box out of its operating position.
- Steam blow boxes are mainly used in papermaking. They are used in particular to raise the temperature of the material web with the help of the steam applied to the material web in order to improve the dewatering of the material web.
- a respective steam blower box offers the possibility of influencing the moisture cross profile of the material web by means of the sectional steam application transverse to the web running direction. Such a steam blow box is described for example in WO 99/41450.
- extension rails and an extension trolley have been used to expand the entire steam blower box.
- Such an expansion is now relatively time-consuming and involves a certain amount of additional parts.
- Such a method is particularly problematic in systems with a guide roller that cannot be lowered.
- the aim of the invention is to provide an improved steam blower box unit and an improved method of the type mentioned at the beginning which ensure quick removal, for example within an hour, and complete maintenance, in which cleaning of all areas on the steam blower box and quick replacement of defective parts is possible without any problems.
- a steam blower box unit with a steam blower box for applying steam to a passing web of material, in particular paper or cardboard web, and with an extension device which is at least partially integrated in the steam blower box and via which the steam blower box opposite in an operating position of the web of material sideways, ie is generally transverse to the web running direction, can be moved out of its operating position and can be retracted into its operating position from its lateral position.
- the entire steam blower box can preferably be moved accordingly via the extension device.
- the extension device comprises an extension aid which can be inserted into the steam blower box and through which the steam blower box is guided when it is being moved out or in.
- the extension aid advantageously has an elongated shape and, when in use, can in particular extend generally transversely to the direction of web travel.

- the extension aid can be used to extend and / or retract the steam blower box into the steam blower box and then remove it again. In principle, however, such an embodiment is also conceivable in which the extension aid remains inserted in the steam blower box even during operation.
- the last-mentioned embodiment brings i.a. the advantage of a reduced set-up time.
- the extension aid can be used in a steam distribution space, in particular steam pipe, of the steam blow box which extends generally transversely to the web running direction.
- extension aid can be used in an additional expansion pipe of the steam blower box that extends generally transversely to the web running direction.
- Such an extension pipe can therefore also be provided in addition to an existing steam pipe.
- the steam blower box is advantageously designed such that its upper part is available as a space for the extension aid.
- the extension aid can advantageously comprise an extension tube.
- the extension tube and the relevant receptacle i.e. the region of the steam blower box receiving the extension tube is of spherical design. It is also particularly advantageous if the steam blower box is provided on the driver side and the carrier side with a spherical support tube which is accommodated in a respective bearing, the running surfaces of the bearings preferably having a shape which is complementary to the spherical support tubes.

- a bolt 154 must be removed in the present exemplary embodiment (see FIG. 16 again, for example).
- an adjusting device 146 for example comprising at least one cylinder / piston unit or at least one hydraulic cylinder, is also provided on the drive side for adjusting the steam blow box between the operating position and the maintenance position.
- this adjusting device 146 comprises a hydraulic cylinder.
- This drive-side actuating device 146 is detachably connected in particular to the drive-side support element 66. In particular for the lateral removal of the steam blower box 12, the connection between this or the drive-side support element 66 and the drive-side actuating device 146 can be released, for example, by removing a bolt 156 (cf. in particular again FIG. 21).
- a lifting frame 148 is provided on the drive side, which can be raised such that the drive-side support element 66 connected to it lifts off the drive-side slide rail 132.
- the drive-side lifting frame 148 When the drive-side lifting frame 148 is raised, the drive-side end of the extension aid 20 provided with rollers 24 is also raised at the same time. At least one upper roller 24 of the extension aid 20 comes into contact with the inner wall of the steam distribution space 22 or the additional expansion pipe 38. With the lifting of the drive-side lifting frame 148, the entire drive-side end of the steam blow box 12 is finally raised.
- a locking bolt 48 passing through the drive-side end of the extension aid 20 and guided in elongated holes 150 of the drive-side bearing 46 is acted upon and carried along, and the drive-side end of the extension aid 20 is also lifted via this locking bolt 48 '.
- the drive-side lifting frame 148 can be raised via an actuating device, which here comprises, for example, two cylinder / piston units or lifting cylinders 152.
- the drive-side lifting frame 148 can be adjusted in particular relative to the drive-side mounting 46 via this adjusting device 152.
- the embodiment of the steam blower box unit shown in FIGS. 15 to 21 thus includes a bearing for extending the steam blower box 12 and for adjusting the steam blower box 12 between an operating position and a maintenance position.
- a frame-like slide rail 130 is provided on the driver's side, on which the support element or support tube 64 rests during operation or slides from the operating position into the maintenance position and vice versa with the aid of the adjusting device 134.
- a lifting frame 138 is also provided on the driver's side, with which rollers 136 and guide elements 142 are firmly connected.
- This operator-side lifting frame 138 is raised by the adjusting device 140, which comprises two hydraulic cylinders, for example, before the steam blow box is removed, as a result of which the rollers 136 with the support element or support tube 64 come into contact and thus lift the steam blower box off the slide rail 130.
- the guide elements 142 are guided in U-shaped guides 144, for example. Before moving out, the upper bearing part 76 must be dismantled and the connection to the actuating device 134 comprising, for example, a hydraulic cylinder must be released.
- the work on the driver's storage therefore includes the following steps, for example:
- the total stroke of 17 mm can be composed in particular as follows:
- Work on the drive-side mounting can include the following steps, for example:
- Raising the drive-side lifting frame 148 by means of the adjusting device 152 for example comprising two short-stroke cylinders (e.g. by 22 mm)
- the total stroke of 22 mm can be composed in particular as follows:
- Embodiment at least essentially have, for example, such a structure as described in connection with the other embodiments. LIST OF REFERENCE NUMBERS
