Description

APPARATUS FOR UNLOADING DEBRIS FROM A PULP DRYER AND A PULP DRYER The object of the invention is an arrangement for unloading debris from a pulp dryer, which is connected to the end of the pulp dryer for leading the debris from the pulp dryer equipped with at least one treatment level to the waste treatment, with the treatment level being fitted between the pulp dryer and the waste treatment, which device includes - control means for leading the debris to the waste treatment, joi- hin control devices include one or more of the following: pull-out device with nips; a flexible debris guide with two ends, the first end of which is adapted to move in the height direction of the pulp dryer and the other end is adapted to the waste handling, - moving means for moving the control means in the height direction of the pulp dryer.

In addition, the subject of the invention is also a pulp dryer.

In accordance with known technology, wreck left inside the pulp dryer in an interrupted situation is unloaded from the pulp dryer using an extraction device with an openable/closeable nip, which is also called a wreck nip.

The waste tip is integrated into the treatment platform adapted to move in the height direction of the pulp dryer.

The scrap nib is then placed in the vertical direction of the pulp dryer N 25 at the bottom edge of the long side N on the side of the pulp dryer, i.e. between the treatment platform and the pulp dryer, or 3 then in connection with the railing of the rear edge of the treatment platform, as shown in pictures N 3a - 3d.

In addition to the wreck nip, a wreck tarpaulin can also be used as an aid in breaking up wrecks, which is also integrated into the treatment O 30 platform.

Through the wreck nip 5 integrated in the treatment bridge, the unloaded pulp dryer wreck flows along the wreck tarpaulin from the pulp dryer to the pulper.

With the state-of-the-art solution mentioned above, it is very difficult to clean the lowest layers of the pulp dryer.

This is especially the case when the opening of the pulper in the dry end of the pulp dryer is high in relation to the lowest layers of the dryer.

In some cases, this can be an area even more than 10 drying layers high, which is close to the pulper opening.

The corresponding problem, i.e. the difficult emptying of the lowest layers of the dryer into the pulper of the dry end, is also present in those dryers where the pulper is lower in its own section.

In this case, the starting point of the pulper's estuary, i.e. the mouth of the wreck processing, forms a hill over which the wreck track must first be raised in order to get it to enter the pulper.

In such solutions, typically 4 - 5 of the dryer's lowest track layers remain "in the street". In a well-known solution, the wreck tarp is attached at one end to a treatment platform adapted to move, which is a device that transports people.

The wreck always exerts a certain load on the treatment platform.

If a large amount of debris accumulates on the tarpaulin, as happens easily, for example, in the covered area of the lower part of the dryer, a load greater than the weight of the debris pulp is applied to the treatment level.

In this case, the care level's overload sensor is activated and the care level gets stuck thanks to its safety function.

O 25 3 The well-known solution also leads to the temptation to try to lift the wreck web from the cover area of the N pulp dryer in such a way that it E is pulled upwards on the moving treatment platform all the way to the level of the pulper opening O.

This is strictly prohibited due to safety and the risk of damage to the mobile care level s 30, but still N it is done because cleaning the lower area of the dryer otherwise N is so difficult and therefore laborious.

Small-capacity pulp dryers do not necessarily have moving treatment levels at all, and therefore neither do they have waste disposal tips. In them, the pulp dryer is completely emptied by human power, i.e. by pulling it by hand. Based on the above, it can be concluded that in general, with all its challenges and problems, wreck crushing is a big problem that has plagued the industry for a long time. Reference is also made to European patent EP 1969179 Bl and German utility model publication DE 202018106912 UIL as state of the art.

The purpose of this invention is to provide an arrangement for unloading debris from a pulp dryer, which facilitates and speeds up the unloading of debris from the pulp dryer. In addition, the purpose of the invention is also to create a pulp dryer with which the demolition of debris is easy and fast, in which case the productivity of the pulp dryer has improved. The characteristic features of the arrangement according to the invention are presented in patent claim 1 and in the patent claim of the pulp dryer

14.

According to the invention, between the waste processing of the pulp dryer and the treatment level of the pulp dryer, there is an arrangement separate from the treatment level for unloading the waste from the pulp dryer to the waste treatment. The control means included in the arrangement are adapted to be moved back and forth independently of the treatment platform O 25 in the height N direction of the pulp dryer. The arrangement makes it easier to clean the pulp dryer and thus also improves its usability.

N E According to one of the first forms of application, the arrangement includes an extraction device that is adapted to function as a wrecking pin. The pull-out > 30 device is then fitted separately from the treatment level and, therefore, it can be moved in the height direction of the pulp dryer N independently of the treatment level as its own unit. Being separated, the wreck handled by the extraction device does not burden the treatment level and does not pose a safety risk to the employees working on the treatment level.

According to another application form, the fitting includes a flexible guide, such as a wreck tarp or other similar fabric or a mat-like device, which is also fitted separately from the treatment surface and which can also be moved in the height direction of the pulp dryer independently of the treatment surface. In this form of application, a pull-out device can also be included, with which the wreck is transferred to a flexible guide. The pull-out device can then be arranged in connection with the treatment table and/or separate from the treatment table, such as for example in connection with the end of the flexible guide adapted to move in the height direction.

In addition to improving cleanability and safety, the invention also improves the productivity of the pulp dryer, because the debris removal made easier by the invention speeds up the cleaning process, thus shortening the idle time of the pulp dryer. With the invention, the demolition of the lowest layers of the pulp dryer, and especially the roof areas, becomes significantly easier. In addition, the invention achieves a special advantage with pulp dryers that have fixed treatment levels. Other additional advantages that can be achieved with the invention appear in the explanatory part and the characteristic O 25 features in the attached patent claims.

3 N The invention, which is not limited to the various forms of application presented below, is explained in more detail by referring to the accompanying pictures, where s 30 N Figure 1 shows, on a principle level, one of the first examples of the arrangement arranged in connection with the end of the pulp dryer in its two different operating situations, viewed from the side , Figures 2a - 2d show the operation of the arrangement shown in Figure 1, viewed in stages from the side, 5 Figures 3a - 3d show, on a principle level, a second example of the arrangement arranged in connection with the end of the pulp dryer and its operation, viewed in stages from the side, and Figure 3d shows, with dashed lines, a third example on a principle level form of implementation arranged in connection with the end of the pulp dryer.

Figure 1 shows, on a principle level, a first example of an arrangement 33 arranged or arrangeable in connection with the end 101 of the pulp dryer 100 for unloading the wreckage W from the pulp dryer 100 and at the same time also an example of the pulp dryer 100 itself viewed from the side. The pulp dryer 100, which the invention also applies to in addition to the arrangement 33, includes turning rollers 102 fitted to its ends 101 in a known manner for guiding the pulp track through the pulp dryer 100 to dry it. The pulp dryer 100 is fitted with either movable or fixed treatment levels 110 according to Figure 1 — for example, at both ends 101 of the pulp dryer 100 to perform operations O 25 for the pulp dryer 100. More specifically, 3 treatment levels 110 are arranged at the ends 101 of the pulp dryer 100 next to the turning rollers 102 fitted. The figures show the reader 100 only partially from the connection of one of its ends 101. O The pulp web passing through the pulp dryer 100 is dried in a known manner s 30 in the pulp dryer 100 by the forming of the overlapping conveyors 3 and turning rollers 102 arranged at the ends 101 even back on the track running between the ends 101.

The ends 101 have openable/closeable hatches 104 or the like, such as, for example, a folding lift hatch or a roll-up hatch (figure 1). They are used to close the openings that allow the pulp dryer 100 to enter during production, through which the pulp dryer 100 can be accessed to apply measures to, for example, the area of the turning rollers 102.

The arrangement 33 according to the invention for unloading the waste W is located with the pulp dryer 100 in connection with its end 101 and is intended to lead the waste W from the pulp dryer 100 equipped with one or more treatment levels 110 to the waste treatment 11. The arrangement can be arranged in connection with at least one end 101 of the pulp dryer 100, where there are Starting from 100, rotating rollers 102 and treatment level 110 arranged either fixedly or movably in the height direction H of the pulp dryer 100. Thus, the treatment level 110 is fitted between the pulp dryer 100 and the waste treatment 11.

The moving treatment table 110 includes a body in a known manner and preferably means adapted to the body for moving the treatment table 110 next to the pulp dryer 100 to the desired height in its height direction H.

The means of movement of the treatment platform 110 can include, for example, guide elements 30 in connection with the rear (or front) edge of the treatment platform 110 with the actuators 31 that cause movement. elevation direction.

With the help of the moving means 31 of the treatment platform 110, the N treatment platform 110 can be moved to a suitable height at the edge of the pulp dryer 100, e.g. in relation to the openings, so that O of them can be used to direct measures to the pulp dryer 100 s 30, for example to its turning rollers 102 or to operate inside it.

3 by the thigh.

The arrangement 33 includes control means 12 for leading the pulp web W to the waste treatment 11 and movement means 14 for moving the control means 12 in the height direction H of the pulp dryer 100. The implementation of the control means 12 can vary. The control means 12 may include one or more of the following: an extraction device 17 with nips 23, a flexible debris guide 13 or even a combination of the aforementioned.

In the case according to the first application form shown in Figure 1, the control device 12 is a pull-out device 17, which includes an openable/closeable nip 23. The nip 23 is now intended, for example, to pull the broken pulp web W out of the pulp dryer 100 and further lead it to waste processing

11. According to one form of application, the nip 23 of the pull-out device 17 is adapted to form a roller 26.1 and separate wheels 26.2 that fit against the roller 26.1. On the other hand, nip 23 can also be formed by two full-length rollers facing each other.

The movement means 14 of the control means 12 include conductors 24 for the movement of the extraction device 17 adapted to the event in the height direction H of the pulp dryer 100. In addition, the movement means 14 also includes the drive 20 and the power transmission means 25 adapted to act on the extraction device 12 in the height direction H of the pulp dryer 100 O 25 to bring about the movement adapted to the event.

N E The movement means 14 O of the control means 12, i.e. the pull-out device 17, is now its own independent unit arranged separately from the treatment 30 level 110 and its possible movement. In other words, the moving means 14 of the N control means 12 are adapted to move the pull-out N device 17, more generally, the control means 12 independently of the treatment plane 110. In addition, the pull-out device 17, more generally, the control means 12 with the movement means 14 are arranged between the treatment level 110 and the debris handling 11.

The pull-out device 17 can be used with a solution similar in basic principle to what is used in known technology, for example, in moving treatment levels 110. However, in arrangement 33, the pull-out device 17 now has its own frame structure on the sides of the track line, along which the pull-out device 17 with wreck nips 23 moves vertically. Exercise can be done in many different ways. One example is the same type of electric motor - guide rails - lifting chain combination, which is used in mobile care levels 110.

Depending on the layout and other equipment of the pulp dryer 100, there are plenty of different implementations based on the extraction device 17. As shown in Figure 1, the mobile extraction device 17 can be at the height H of the entire pulp dryer 100, and the mobile treatment platform 110 then does not have its own extraction device at all.

According to another application, the independently moving extraction device 17 can be at the height H of the entire pulp dryer 100, and the moving treatment platform 110 can have its own extraction device 17" (Figures 3a - 3d). According to a third application form, the independently moving extraction device 17 can be the entire length of the pulp dryer O 25 100 at a height H, and the pulp dryer 100 does not have a movable treatment level at all, but fixed treatment bridges 110 instead of movable N treatment levels 110 (figure 1). This is a particularly advantageous form of application with small-capacity pulp dryers, where the demolition has always been done by human power, i.e. by pulling by hand. s 30 One definition of a small capacity pulp dryer can be N, for example, such that its track width is four meters or N less than that.

Figures 2a - 2d show the operation of the arrangement shown in figure 1 in stages, viewed from the side, now as an application form of the mobile treatment level 110. Here, the delta 28 of the pulper 27 belonging to the waste treatment 11 covers the layers of the lower part of the pulp dryer 100, and in order to obtain the pulp web W for the delta 28, it must be raised from the level A of the layers of the lower part of the pulp dryer 100 to the level of the mouth 15 of the waste treatment 11. The floor level of the machine is marked with the reference number 36. Thus, in the form of application shown in figures 2a - 2d, the wires 24 of the control means 12, i.e. now the extraction device 17, are adapted to extend to the area below the mouth 15 of the waste treatment 11 A in the height direction H of the pulp dryer 100. The area above the mouth 15 of the waste treatment 11 can be treated first - with the debris guide 13' marked in figures 2a — 2d from the treatment bridge 110 by hand. According to Frä's application form, the principle of operation of the movable pull-out device 17 adapted separately from the treatment surface 110 can be, for example, as follows. The extraction device 17 with the wreck nips 23 is driven according to figure 2a to the height of the drying layer of the pulp dryer 100, from where the wreck W is to be cleaned and taken to the wreck treatment 11. The end of the wreck track W is pulled, for example, by hand through the open wreck nip 23. This happens exactly — in the lowest layers of the pulp dryer 100, working on the floor 29 O 25 and higher up, for example, working on the moving treatment platform 110 3.

N E As shown in Figure 2b, the wreck nip 23 is closed and the pulp track W is pulled with the wreck nip 23 onto the floor 29. Track W is drawn through the wreck nip 23, for example so much that its length 3 corresponds to the height difference between the layer to be cleaned and the pulper estuary 28.

As shown in Figure 2c, the wreck nib 23 is opened and the wreck nib 23 is driven upwards in the conductors 23 arranged for it.

As a result, the wreck track W driven on the floor 29 is as if wound "backward" in the open wreck nip 23. As shown in Figure 2d, the wreck nip 23 is driven to the height of the upper edge of the pulper 27 estuary 28, i.e. the mouth 15 of the wreck handling 11, and is closed there again.

After closing, the scrap nip 23 starts pulling web W from the pulp dryer 100, as a result of which the scrap nip 23 feeds the scrap web W to the pulper 27 from the drying layer of the pulp dryer 100 below its own position,

which is therefore in area A.

The moving treatment platform 110 or the fixed treatment platform 110" and the wreck nipper 23 arranged independently of it and adapted to move are arranged at a distance from each other.

In this case, there is no risk of crushing.

Securing the wreck track W from the working position to the mobile wreck nip 23, i.e. from the mobile or fixed treatment platform 110, 110', can also be implemented, according to one application, with a mechanical solution, for example, in which the treatment platform 110 is equipped with missiles fitted to its safety rail (not shown), which are arranged - able to guide the pulp web W towards the wreck nip 23. The guides — can then be a kind of downhill guardrails, O 25 where the wreck nip 23 is at the level of their lower end and thus lower than the upper edge of the safety rail of the treatment level 110.

Along the guide N, the pulp W can be drained from the treatment level 110 by hand into the hopper 23 and there is no need, for example, to reach over the safety rail of the treatment level 110.

In addition, the guides can s 30 be turned away from their position leading to the wreck nip 23, for example horizontally.

In this case, they can be arranged parallel to the safety rail N.

Various automation solutions can also be used for security, such as light curtains, limit switches, etc. Various combinations of mechanical and automation solutions are also possible. Figures 3a - 3d show, on a principle level, another example of the arrangement 33 arranged in connection with the end 101 of the pulp dryer 100, viewed from the side. In the presented embodiment, the guide means 12 now comprise a flexible debris guide 13 fitted between the treatment level 110 and the debris treatment 11. The flexible debris guide 13 has two ends 19.1,

19.2. Among them, the first end 19.1 is adapted to move in the height direction H of the pulp separator 100. The second end of the debris guide 13

19.2 is, in turn, adapted to the connection of the debris handling 11 and even more specifically, now to the connection of its mouth 15. In the same way as in the case of the pull-out device 17, here too the moving means 14 of the control means 12, i.e. the flexible debris guide 13, is its own independent unit. Thus, here too, the arrangement 33, i.e. especially the control means 12, is arranged separately from the treatment level 110 between the treatment level 110 and the debris processing 11 in order to move the control means 12 independently of the treatment level 110.

The movement means 14 of the control means 12, now the flexible debris guide 13, include guides 24 for the movement of the flexible debris guide 3 13 adapted to the event in the height direction H of the pulp dryer 100 25. The conductors 24 are now located on the treatment and operating side of the pulp dryer N 100, i.e. on the edges of the track. In addition, the movement means 14 also include the drive 20 and the power transmission means 25 adapted to act on the flexible debris guide 13 s 30 in the height direction H of the pulp dryer 100 in order to achieve a movement adapted to the event. The flexible guide 13 now acts as a tarpaulin 22, which can also be called a wreck tarpaulin in this context, a fabric or other similar mat-like material which is strong enough, but still flexible, so that it can be formed, for example, into a bag-like but also straightening tool for the wreck W or that it can be rolled up, for example. The flexible guide 13 is adapted mainly to the entire width of the pulp dryer 100. It can be equipped with edge reinforcements on its edges between the ends 19.1, 19.2. A support 16 is fitted to the conductors 24 belonging to the moving means 14, to which the first end 19.1 of the flexible guide 13, i.e. the end 19.1 towards the pulp dryer 100, is fitted in order to move it with the moving means 14 in the height direction of the pulp dryer 100 H. The support 16 can be, for example, a round bar or a beam that is attached as leads to 24 working vertical posts. The motor acting as drive 20 and the drive equipment acting as power transmission 25 move the supporting 16 working round bars up and down, while at the same time moving the side end of the tarp pulp dryer 100

19.1 with him. Thus, there is no need to wind the tarpaulin on the round bar, but the round bar is only moved up and down by, for example, chain drive or lifting slings. Without winding, the lifting mechanism is simple. The other end 19.2 of the flexible guide 13 is, in turn, adapted — to the debris handling 11, more specifically, to its mouth 15. There, O 25 can be a corresponding type of support, such as, for example, a round bar 3 or a beam to which the edge of the guide 13 is attached.

N E In the presented embodiment, at least one of the ends 19.1, 19.2 of the flexible guide 13 O can be equipped with winding means 21 or 30 to change the length of the wooden guide 13. In the embodiment shown in 3, this end is the end 19.2 of the flexible guide 13 on the debris handling 11 side. The winding means 21 include a rotation motor 32 for rotating the coil. The tarpaulin 22 can be wound around the tarpaulin roller and thus adjust the length and tension of the tarpaulin 22 in use.

According to Frä's application form, the arrangement 33 can also include other moving means 18 at the other end of the flexible guide 13

19.2 to move the pulper at the end on the 27 side horizontally. The moving means 18 include wires along which the tarpaulin roller, or support, can be moved a short distance between, for example, the production position and the cleaning position. To move the tarpaulin roll horizontally, you can use, for example, a hand crank / winch, cylinders or a similar device, with which, for example, fabric tensioning rolls are moved.

Figures 3a - 3d show the operation of the arrangement 33 with the flexible guide 13 and its spooling end 19.2 on the pulper 27 in stages, viewed from the side. In this embodiment as well, the estuary 28 of the pulper 27 belonging to the waste processing 11 covers several layers of the lower part of the pulp dryer 100, and in order to obtain the pulp web W for the mouth 15 of the estuary 28, it must be raised from the level of the layers of the lower part of the pulp dryer 100 to the level of the mouth 15 of the pulp dryer 11 A. Thus, in the form of application shown in figures 3a - 3d, the conductors 24 3 arranged on one top 19.1 of the control means 12, i.e. now or O 25 the wooden guide 13, are adapted to extend to the lower side of the mouth 15 of the waste treatment 11 in the area A in the height direction of the pulp dryer 100 H. = a O In the presented embodiment, the fitting 33 includes the flexible guide 13 as a control intermediate 30, and now also the pull-out device N 17, 17" with nibs 23. The pull-out device 17" can be adapted to the connection of the treatment level N 110, for example to its outer railing and/or also to the wires 24 arranged on the flexible guide 13 connection, depending on, for example, the implementation of the treatment bridge 110. In the presented embodiment, the extraction device 17 is intended for moving the waste W from the pulp dryer 100 to the flexible guide

13.

According to Frä's application form, the principle of operation of the flexible guide 13, which is separated from the treatment surface 110 and adapted to move at least one end 19.2 of the pulp dryer 100 in the height direction H, can be, for example, as follows. The end 19.2 of the flexible guide 13 towards the pulper 27, equipped with the winding feature, is moved along the guide rail belonging to the horizontal movement means 18 to the upper end of the pulper 27 estuary 15 and locked in place in the arrangement shown in figure 3a. The movable treatment platform 110 can be driven in its own guides 30 arranged for it to the height from which the wreck W is to be cleaned from the pulp dryer 100, unless the cleaning then takes place, for example, from the floor level 29, as is almost the case in Figures 3a — 3d.

The end 19.1 of the flexible guide 13 towards the pulp dryer 100 is also moved, as shown in figure 3a, to the height from which the wreck W is to be cleaned from the pulp dryer 100.

At the same time, the flexible guide 13 is driven loose using the rotation motor 32 belonging to the winding means 21 of the tarpaulin roll so that, — in the guide 13, a "bag" O 25 remains between its ends 19.1, 19.2 for the scrap pulp W to be collected by the flexible guide 13. Next, the wreck W is pulled from the pulp dryer 100 in a higher position N, either with the wreck nipper 17" of the mobile treatment platform 110 onto the wreck cypress 22 or, if it is below the 15 o level of the mouth of the pulper 27, the wreck track W is collected on top of the wreck tarp 22 into > 30 rolls / heaped / folded for example, the length of one drying layer of the pulp dryer 100 3. When the wreck track W is tarpaulin

22 on a suitable amount, track W is cut off, ending up in the situation shown in figure 3b. Next, the 100 side end of the wreck tarpaulin 22 pulp dryer

19.1 is raised in its wires 24 and drive 20 a few meters higher than the elevation of the mouth 15 of the pulper 27 estuary 28 to the layout according to figure 3c. The moving treatment platform 110 can remain in place during the lifting of the wreck W, if it was used to collect the wreck W and transfer it to the guide 13. The wreck roller is tightened with the help of the tarpaulin roll rotation motor 32 until the wreck tarpaulin 22 is so tight that the wreck pulp W on top of the tarpaulin 22 slides by itself into the pulper 27 by gravity. Figure 3d shows this situation. An automatic stop can be programmed for the control of the wreck roll rotation motor 32, which prevents the wreck tarpaulin 22 from being too tight. If the wreck removal is carried out above the level of the mouth 15 of the pulper 27, the wreck removal can take place in a similar way as in the known solution — the wreck slides along the wreck tarpaulin 22 to the pulper 27. In this case, the wreck tarpaulin 22 is driven using the wreck roll rotation motor to a suitable tension according to the current operating height. — In the production situation of the pulp dryer 100, both O 25 ends 19.1, 19.2 of the wreck tarpaulin 22 are driven to such a position that the tarpaulin 22 is not 3 on the line of the pulp track.

N E In the application form shown above in Figures 3a - 3d, the other end 19.2 of the flexible O guide 13 in connection with the pulper 27 was equipped 30 with other moving means 18 to move it horizontally between the debris removal position and the production position and, in addition, with a winding feature. According to another application form, the corresponding functions can be implemented, for example, with a rotating extension 34 of the pulper 27 arranged at the upper end of the mouth 28 of the pulper 27 instead of the movable press roll shown in figures 3a to 3d. This form of application is shown only in figure 3d, where the extension 34 of the estuary 28 is shown with dashed lines in its two operating positions. The flexible guide 13 implemented with the tarpaulin 22' implemented with the curb extension 34 is always located on the right side of the pulp track and the tarpaulin or the tarpaulin 22' does not cut the track line. Consequently, with this form of application, the horizontal movement means 18 of the press reel are not needed at all. In other words, in this embodiment, the end 19.2 of the flexible guide 13 on the side of the pulper 27 is at a distance from the mouth 15 of the waste treatment 11, so that there is sufficient free space between the mouth 15 and the end 19.2 of the flexible guide 13 for the production position, when the extension 34 of the estuary 28 is turned to its left-hand position closing the mouth 15 of the pulper 27. Extension 34 can also be referred to as a hatch. Thus, the escutcheon 28 can be said to be movable, such as, for example, the rotatable extension 34.

— In addition to the previous one, the 22" winding of the tarpaulin may not be necessary for the O 25 at all either. In other words, the length 3 of the flexible guide 13 may be fixed. The support N 35 of the second end 19.2 of the flexible guide 13, i.e. the attachment point, can now be formed, for example, by a simple E elongated round bar without a winding feature. In this case, the end 19.2 of the flexible guide 13 on the side of the pulper 27 is without > 30 coils, i.e. fixed, and also at a distance from the mouth 15 of the wreck treatment N 11. Thus, in this application form, the tarpaulin 22' is only raised from its first end 19.1 higher than its first end 19.1 in order to unload the wreck W, an extension of the estuary 28 34 along to the wreck treatment 11. With the invention, the wreck press, tarpaulin roller and counterweight system attached to the mobile treatment platform 110 can be dispensed with completely, and thus the load applied by the wreck pulp W to the mobile treatment platform 110 can be completely eliminated.

In addition, with the invention, the possibility of misuse is also removed and work safety is improved.

The arrangement 33 according to the invention can also be used for cleaning the cooling layers located at the very bottom in the pulp dryer 100.

The end 19.1 of the wreck tarpaulin 22 towards the pulp dryer 100 can be driven/moved up to the basement floor 29.

Arrangement 33 can be arranged in both the dry and wet ends of the pulp dryer 100. For the dry end pulper, you do not need a pulper assembly to clean the pulp dryer.

As can be seen above, the arrangement 33 according to the invention has numerous different implementations.

The moving scrap nipper 23 can be at the entire height of the pulp dryer 100 or only in the "roof area" of the pulp dryer 100, and the movable treatment platform 110 can have its own extraction device 17' with its scrap nippers.

The wreck tarp 22 can be connected to either a mobile wreck nipper 23 or a mobile treatment platform 110, depending on the layout.

It is also possible to omit the wreck tarp 22 completely by modifying the estuary 28 of the pulper 25 O 25. At one end 3 of the pulp dryer 100 there can be a movable treatment level 110 and at the other end a movable N wreck nip 23. = a O The invention achieves several significant advantages.

With s 30 of the invention, the demolition of the lowest layers of the pulp dryer 100 and especially the roof areas A below the mouth 15 of the estuary 28 becomes easier.

With the help of the independently moving wreck nip 23 and/or the flexible guide 13, it is possible to completely dispense with the movable treatment levels 110 of the pulp dryer 100, which are expensive devices. The moving wreckage nip 23 and/or the flexible guide 13 are easier devices in terms of safety than the mobile treatment platform 110, because people are not transported with the wreckage nip 23 or the flexible guide 13. The implementation is suitable for new pulp dryers 110 as well as for existing ones to be implemented as a retrofit.

It must be understood that the above explanation and the related pictures are only intended to illustrate the present invention. The invention is thus not limited only to the embodiments presented above or defined in the patent claims, but many different variations and modifications of the invention that are possible within the framework of the inventive idea defined in the accompanying patent claims will be obvious to the person skilled in the field.
