    DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTIONI fi g. 1a and 1b, a pulp processing device 1 is shown in the form of a washing machine.press in an overview view. Ifig. 1a is the device in a working position and in fi g. lb isthe device in a service position. In the service mode, the device's movable door 2open for the purpose of allowing access to the interior of the pulp processing device 1.
    In the working position, pulp is fed through a fixedly arranged feed pipe 4 to an inletflue pipe 3, which is integrated or fixedly connected to the door 2 on the deviceFor the sake of visibility, only a part of the feed tube is shown in FIG.rs la and lb. The feed tube 4 is connected to a feed unit, from whichpulp is fed through the feed pipe 4 and the inlet pipe 3 and into the processing1.
    As shown in fi g. 1b, the inlet pipe 3 must be disconnected from the fixedarranged the feed pipe 4 to allow the door 2 to be från removed from the working positionaccording to fi g. added to the service level according to fi g. lb. The acquisition refers to improvements inconnection with the connection of these pipes.
    Figures 3-5 show a specific embodiment of the invention from differentangles. I fi g. 2 indicates where the different views are taken from, with Romannumbers III-V, corresponding to Figures 3-5. Thus, the device is shown inFigures 3a, 3b and 3c in the view referred to in section III-III.
    Now, a specific embodiment of the invention will be described, withreference to Figures 3a-3c. Figure 3a shows the device in a working positionand in fi g. 3b, it is displayed in a non-workable service mode. Fig. 3c, is adetailed view of a part of Fig. 3a and thus also shows the device in workinglocation.
    The feed pipe 4 is connected to the inlet pipe 3 by means of a locking member 13, whichis part of the invention and comprises two pivotable arms 14 and 15.
    The ends of the pipes each comprise a circumferential fl åns, a first circumferentialfl as 5 on the inlet pipe 3 and a second circumferential fl as 6 on the supply pipe4. Both ends comprise an inner radial contact surface, which is adaptedfor mutual connection, wherein the connection between the circumferential fl10152025303540The contact surfaces of the surfaces 5 and 6 comprise a seal 9 to ensure atight connection in between. In the embodiment shown, the seal is formed9 of an O-ring arranged in a circumferential groove 11 in the radialthe surface of the second circumferential fl end 6. Different types of fl leak sealHowever, they are known to those skilled in the art and the invention is notlimited to any specific type of seal.
    An important part of the invention is that the first circumferential axisfurther comprises a longitudinal portion 12, which is arranged on a slidableand fl leaky way in relation to the inlet pipe 3. The first circumferentialThe end 5 can thus be moved along a longitudinal axis A1 of the inlet pipe.3 between the fl leaky connection of the inner radial surfaces of thecircumferential 5 ends 5 and 6 to a second position in which they are radialthe surfaces of the circumferential fl ends 5 and 6 are separated from each other.
    Accordingly, the connection of the circumferential 5 ends 5 and 6 can providecome and be released without either of the two tubes 3 or 4 having to fl surfacetas; instead, only one of the fl ions is mobile.
    In the specific embodiment shown, the first circumferential 5 is 5coaxially arranged on the outside of the inlet pipe 3. The connection between the inlet pipe3 and the first circumferential 5 end 5 is of course fl sealed, so that noa mass or the like can leak from the inside of the pipe. It is, of coursealso possible to arrange a slidable circumferential fl end on the feed pipe 4,instead of on the inlet pipe 3. A special object of the invention is toprovide that the connection can be made and disconnected without any of themtwo pipes 3 or 4 are flattened. In the preferred embodiment this is achievedby allowing one of the fl ends to be so arranged that it can fl be extended into the corresponding pipe. Of course, it does not matter which offl the ones that are fl superficial.
    As mentioned above, the inlet pipe 3 is connected to a hatch 2 on the massthe processing device 1 for dewatering and / or washing pulp, whichdoor 2 can be pivoted away from a working position in which theends 5 and 6 can be connected to each other, to a service position inwhich the circumferential fl ends are not intended to be connected. An advantagewith the invention is that in the service mode there is an opening between the twofl the ends 5 and 6 so that the door 2 and the inlet pipe 3 can be swung away withoutrisk of collision between the inlet pipe 3 and the supply pipe 4.
    In the embodiment shown, the longitudinal axis lines A1 and A2 are forthe inlet pipe 3 and the feed pipe 4, respectively, are parallel in relation to each other,and in the working mode they are t.o.m. coaxial in relation to each other. The door isarranged to pivot in a direction which is substantially perpendicular to the relationshipto the longitudinal axis lines A1 and A2 of the pipes, so that the axis lines A1and A2 are still parallel to each other in the service mode,even if they are not coaxial.10152025303540The locking means 13 for locking the slidable first circumferential 5 end 5 inthe fl leaky connection comprises two pivotable arms 14 and 15arranged on radially opposite sides of the circumferential 5 ends 5 and 6.
    The pivotable arms 14 and 15 are arranged to pivot about an axis 10arranged on the locking member 13, which in turn is arranged on the inlet pipe 3.
    Both the pivotable arms 14 and 15 comprise a contact member 16 forcontact the outer radial surface of the sliding first circumferential fl end-then 5 and press said fl äns 5 against the other circumferential fl änsen 6 inin the fl leaky connection.
    The pivotable arms 14 and 15, which may be of a conventional knowntype are hydraulic, pneumatic or electrically controlled and are so arrangedthat they may be self-locking in the closed position after pressing theinto the fl leaky working position, in order to avoid unwanted opening whenof. In operation, the pipes 3 and 4 are fixed in relation to each other, so that the forcesacting on fl axes 5 and 6 depends only on the internal pressure of the massinside the tube. In addition, the pressure of the mass inside the tube acts, due to pipe outletshaping, primarily in the radial direction and not in a direction such asforces apart fl änsarna. This is due to the fact that virtually no parts of thethe surfaces are accessible from the inside of the tube 3 and 4 when the 5 ends 5 and6 are connected. Thus, the forces acting to separate the ns ends 5and 6 from each other relatively small, so that the counterforce provided bythe pivotable arms 14 and 15 are large enough to prevent connectionfrom an unwanted opening during operation.
    Figures 4a and 4b show the tube from the line IV-IV in fig. 2, i.e. from the counter-set the page in relation to the sectional views in Figures 3a-c. In addition,Figures 4a and 4b are not sectional views but ordinary side views so that details on the outsidethe tube is visible. For example, two spring devices 18 are visible in the figures4a and 4b. The spring devices 18 are arranged to operate in the separating device.the direction of the fl ends, in such a way that the sliding firstcircumferential 5 äns 5 is withdrawn from the other circumferential fl änsen 6,in order to facilitate the opening of the connection between fl ends 5 and 6. Ithe specific embodiment shown, four capercaillie devices are provided,two of which are visible in ñgurema 4a and 4b. I ñg. 4a, which shows the device genein the working position, the spring devices 18 are in a retracted state, and inthe service position shown in Fig. 4b, the spring devices 18 have acted into oneextended, or at least less compressed state.
    In Figures 5a and 5b, two spring devices 18 are shown which are arranged onopposite sides of the circumferential 5 ends 5 and 6 in a view along the section V-V i tig. 2, in the working mode and the service mode, respectively. Fig. 5c shows the upper of thesaid spring devices 18 in detail and in the working position.
    In the operating position shown, the spring 19 in the spring device is in a compressed position.stand between a first support 20 attached to the inlet pipe 3 and two nuts 2 1ka are arranged on a bolt 22 around which the spring 18 is arranged. The10the opposite end of the bolt 22 is in turn connected to the first circumferentialwalking fl änsen 5, via a second support 23 in order to press said fl äns 5away from the second circumferential 6 axis 6 under the action of the spring 19.
    This device facilitates the disconnection of the connection betweenthe flanges so that also the removal of the door 2 from the pulp processing ~the device 1 is facilitated. This improves access to the inside ofthe device.
    The invention has been described above with reference to specific embodiments.former; However, the invention is not limited to any of thesecoffee designs. Instead, the acquisition is limited only by the followingthe scope of the claims.
