    MONOBLOCK ANNULAR BANDAGE FOR DIFFUSER
    Invention background
    The present invention relates to the field of its manufacture of sugar from a plant, and more specifically the step of extracting sugar from the plant. The extraction process consists of collecting the sweet juice, which is then filtered and concentrated by evaporation before crystallization.
    The sweet juice is generally extracted by diffusion from thin strips of beet roots, called cossettes. This operation, based on the principle of osmosis, aims to pass the sugar contained in His pods in water.
    To carry out this extraction by diffusion, a horizontal diffuser is generally used provided with a rotary cylinder, such as for example that described in GB 1 375 280. The pods penetrate there by a first end and move in the axial direction according to a first direction, while water, generally lukewarm, circulates in its axial direction of the cylinder, in a second direction, opposite to the first direction. The water inlet generally takes place at the second end of the cylinder, opposite the first end.
    During its axial movement towards its first end, the water is enriched with sugar from the pods, continuously. The sweet juice is then collected at the first end, while its spent sugar pods are evacuated by its second end.
    According to this continuous diffusion method, the cylinder is rotated about its longitudinal axis which is horizontal.
    To do this, the cylinder is provided with several annular tires which cooperate with drive rollers, called rollers, actuated by motors. Generally, each annular tire is supported on a free roller (free roller) and a drive roller (drive roller) whose rotation causes the cylinder to drive in rotation.
    Traditionally, its bandages are made in several parts to allow their mounting around the cylinder wall.
    However, such a configuration requires precisely positioning its parts of the bandage with respect to each other in order to
    BE2016 / 5817 to ensure that the axis of the tire is properly aligned with that of the cylinder, failing which the rotation of the cylinder is likely to generate vibrations which can damage the extraction device. Such precise positioning is however delicate and time-consuming to implement.
    Subject and summary of the invention
    An object of the invention is to propose an annular bandage making it possible to avoid the aforementioned drawbacks.
    To do this, the invention relates to an annular bandage of a horizontal diffuser cylinder for the extraction of juice from chips, is a one-piece annular bandage having a main axis and extending radially, according to a radial height, between an inner peripheral face and an outer peripheral face, said one-piece annular bandage extending axially, in an axial thickness, between a first annular side face and a second annular side face, the one-piece annular bandage being formed in one piece and comprising furthermore a plurality of first openings opening into the first annular lateral face as well as a plurality of second openings opening into the first openings and into the inner peripheral face, the first and second openings being configured to receive position adjustment members one-piece annular bandage relative to the cylinder.
    The fact that the annular bandage is formed in one piece, that is to say one piece, makes it possible first of all to avoid the risk linked to an incorrect positioning between the different parts of the bandage, risk that one encounter in the anterior bandages. Then, this reduces the assembly time, the bandage being simply threaded axially around the cylinder or else previously fixed to a ferrule which is then secured to the cylinder. The annular bandage according to the invention is also more robust thanks to its one-piece structure.
    Furthermore, the mounting of the tire on the cylinder is facilitated by the fact that the adjustment members can be introduced laterally into its second orifices via the first orifices which open into the first annular lateral face.
    BE2016 / 5817
    The adjustment members serve to correct its coaxiality of the tire by aligning the main axis of the annular tire with that of the cylinder before its biasing of the tire to the cylinder.
    It will be understood that the adjustment members are positioned in the second orifices during the adjustment operation. To do this, the adjusting members are first introduced into the first orifices before being positioned in the second orifices. The arrangement of the first and second orifices makes it possible to quickly position the adjustment members, which also contributes to facilitating the operations of mounting the tire to the cylinder. After the adjustment operation, the adjustment members are removed from the annular bandage. It is specified here that the tire can be mounted directly on the cylinder or else indirectly via a ferrule which is fixed to the cylinder.
    Advantageously, the annular tire also comprises a plurality of third orifices, similar to the first orifices but opening into the second annular lateral face, and a plurality of fourth orifices, similar to the second orifices and opening into its third orifices and into the inner peripheral face. Preferably, the third and fourth holes are symmetrical to the first and second holes with respect to a median plane which is orthogonal to the main axis of the annular bandage. The third and fourth ports are also configured to receive adjusting members.
    It is specified that the terms "axial", "radial", and "orthoradiaî" are defined in ia this description with respect to the main axis of the annular tire. This annular bandage is preferably made of steel.
    Advantageously, the first orifices are cavities formed in the annular bandage, while the second orifices are holes extending radially between the inner peripheral face and the cavities.
    The holes are dimensioned to receive the adjustment members, the latter extending radially to come into contact with the cylinder. Preferably, the adjustment members are jack screws, the head of which protrudes into the cavities formed by the first and third orifices, this
    BE2016 / 5817 which allows easy adjustment. These jack screw rods extend into the holes formed by the second and fourth orifices.
    Preferably, the bandage according to the invention has a central part which extends radially over substantially half of its radial height of the annular bandage from its inner peripheral face, and said central part comprises said cavities.
    In other words, its cavities are arranged in the central part of the annular bandage, near the cylinder. This configuration makes it possible to offer a large radial thickness of material between the cavities and its outer peripheral face, which improves the robustness of the tire.
    Preferably, the axial depth of the cavities is less than a quarter of the axial thickness. This configuration makes it possible to offer a large axial thickness of material between the cavities, which further improves the robustness of the tire.
    Advantageously, its length of the cavities, considered in an orthoradia direction, is at least equal to 1.5 times the radial width of the cavities. Also, the cavities have an oblong shape large enough to allow the operator to easily position the adjustment members in its second cavities, or to remove them from the bandage after the adjustment operation.
    Preferably, its radial width of the cavities is less than its half of the radial height of the annular bandage. The cavities therefore occupy a volume substantially less than that of the material constituting the tire, so as to ensure the mechanical robustness of the tire.
    Advantageously, the axial thickness of the annular band considered between two first adjacent orifices is constant over substantially the entire radial thickness of said annular band. The bandage according to the invention is therefore massive, which also contributes to its robustness.
    Preferably, the cross section of the annular bandage, considered in a plane containing the main axis, has a general shape that is at least quadrangular, for example rectangular or trapezoidal. Still advantageously, the inner peripheral face having a convex shape. The convex shape of the inner peripheral face makes it possible to position adjustment shims between the annular tire and the cylinder.
    BE2016 / 5817
    More preferably, the convex inner peripheral face comprises at least two annular faces inclined relative to one another. Thanks to this conformation, the convex inner peripheral face of the bandage comes into contact plane on plane against its adjustment shims, thereby improving the stability of the assembly.
    According to a preferred embodiment, the one-piece annular bandage according to the invention further comprises a plurality of recesses, formed in the first annular lateral face, the recesses being disposed between some of the first orifices and its inner peripheral face.
    These recesses have the function of receiving blocking members which are fixed relative to the cylinder, in order to immobilize the tire relative to the cylinder. The recesses preferably have an orthoradial length which is less than that of its cavity.
    Preferably, its second orifices have radial axes which are arranged axially between the first and second annular lateral faces. Thanks to this conformation, the mounting members, considered in its axial direction of the annular bandage, extend between its first and second lateral faces.
    According to an advantageous embodiment, the external peripheral face of the one-piece annular bandage has a roughness Ra, according to its ISO standard 4287, less than or equal to 7 micrometers, preferably less than or equal to 4 micrometers. This particular surface condition allows a "soft" drive while avoiding the appearance of vibrations during the drive in rotation of the cylinder by the rollers.
    The invention also relates to a method of manufacturing a one-piece annular bandage according to the invention, in which the annular bandage is molded in one piece, its first and second orifices then being produced by removing material after molding.
    Such a method has the advantage of being simple to implement and makes it possible to obtain a one-piece bandage which is solid and robust, and therefore having a longer service life than its traditional bandages. In addition, it makes it possible to easily obtain the aforementioned advantageous surface condition.
    BE2016 / 5817
    According to another variant, the annular tire could be produced by forging.
    The invention also relates to a drive assembly comprising a ferrule having a first axis, and an annular bandage according to the invention, as well as a plurality of wedges, the annular bandage being disposed around the viroie, the wedges being disposed between the shell and the inner peripheral face of the annular bandage.
    The ferrule has a cylindrical shape and is intended to be fixed to the diffuser cylinder.
    To manufacture the drive assembly, the ferrule is placed so that its first axis is vertical. Then put on the annular bandage from above. Then the coaxiality of the annular bandage is adjusted relative to its ferrule, after which a part of the shims is placed between its ferrule and its annular bandage. The annular bandage is then fixed on the road using blocking devices described below. The ferrule is then tilted with the annular bandage so that the first axis of the ferrule is horizontal. We then weld its viroie to the cylinder before checking the coaxiality of the annular tire with respect to the cylinder. The remaining wedges are then placed between the annular bandage and the ferrule, then the wedges are welded with the ferrule.
    Advantageously, the drive assembly according to the invention further comprises adjustment members, arranged in the first and second orifices and configured to cooperate with the peripheral surface of the ferrule to allow adjustment of the coaxiality of the first axis of ia and main axis of the one-piece annular bandage.
    The actuation of the adjustment members, preferably but not exclusively constituted by jack screws, makes it possible to rotate the annular bandage with respect to the viroie, which makes it possible to quickly adjust the position of the main axis of the bandage with respect to the ferrule, so that the main axis of the tire is coaxial with the first axis of the ferrule.
    To secure the annular bandage rnonobloc to its ferrule, the drive assembly also preferably includes blocking members fixed to the ferrule and cooperating with the recesses in the bandage. These blocking members preferably have the
    BE2016 / 5817 form blocks which are housed in the recesses before being welded to the ferrule. These blocks are preferably made of metal.
    The invention finally relates to a horizontal diffuser for extracting juice from chips, comprising a diffusion cylinder having a longitudinal axis which is horizontal, said diffusion cylinder comprising at least one drive assembly according to the invention, in which the main axis of the annular tire, and the longitudinal axis of the diffusion cylinder are coaxial.
    The attachment of the drive assembly to the cylinder is preferably carried out by welding.
    It is also understood that the invention makes it possible to efficiently and quickly carry out operations for replacing damaged cylinder parts. Another advantage of the invention is to be able to easily manufacture the drive assembly in the workshop, unlike the prior art which generally requires assembly on site.

    Detailed description of the invention
    Figure 1 partially illustrates a horizontal diffuser 10 for the extraction of sugar juice from beet root pods. The horizontal diffuser 10 comprises a diffusion cylinder 12 having a longitudinal axis qui which is horizontal. In this example, the cylinder has a diameter of the order of six meters, and a length of about fifty meters. The horizontal diffuser 10 comprises extraction means by diffusion arranged in the cylinder 12. These means are known elsewhere and will not be described in detail here. An exemplary embodiment of such extraction means is described in particular in document GB 1 375 280.
    For its rotation of the cylinder 12 around its longitudinal axis A, the diffuser comprises a drive assembly 14, fixed to the cylinder 12, and carried by two rollers 16 arranged in the self, namely a free roller and a roller training. These rollers are rotatable about horizontal axes of rotation, and parallel to the longitudinal axis A of the cylinder 12.
    The drive assembly 14 includes a ferrule 18 which is fixed around the cylinder 12. More precisely, the ferrule 18 is welded to the cylinder 12, the latter being fitted inside the ferrule 18.
    The drive assembly 14 also comprises an annular bandage 20, in accordance with the present invention which is fixed to its track 18.
    As can be understood with the help of FIG. 1, the annular bandage 20 surrounds the cylinder 12 and rests on each of the two rollers 16. The rotation of the drive roller causes the drive in rotation around S ' longitudinal axis du of the annular tire 20 and, consequently, the rotation of the cylinder 12.
    Using Figures 2 to 6, we will now describe in more detail the annular bandage according to the invention.
    BE2016 / 5817
    In FIG. 2, the one-piece annular bandage 20 has been illustrated in front view. The annular tire 20 has a main axis C which is perpendicular to the plane of its view from its FIG. 2.
    The annular tire 20 extends radially along a radial height H between an inner peripheral face 22 and an outer peripheral face 24. In this example, the radial height H is of the order of 450 mm.
    The one-piece annular bandage 20 also has an internal diameter D which is of the order of 6400 mm.
    Referring to Figures 1, 3 and 5, it can be seen that the annular bandage 20 extends axially along an axial thickness E between a first annular side face 26 and a second annular side face 28. In this example, the axial thickness E of the annular bandage 20 is of the order of 730 mm.
    Referring again to FIG. 2, it can be seen that the annular bandage 20 has a plurality of first orifices 30. The first orifices 30 constitute cavities 32 of obionic shape which are formed in the annular bandage 20. As can be understood from with the aid of FIGS. i, 5, 6, the first orifices 30 open into the first annular side face 26.
    In this example, as illustrated in FIG. 2, the annular bandage 20 has sixteen first orifices 30 which are angularly distributed evenly along its circumference of the bandage. Obviously, without departing from the scope of the present invention, the annular bandage 20 could comprise a different number of first orifices 30.
    As mentioned previously, the first orifices constitute cavities 32. These cavities 32 are arranged in a central part 20a of the annular bandage 20, this central part 20a extending radially over substantially ia half of the radial height H of the one-piece annular bandage 20 from the inner peripheral face 22 towards the outer peripheral face 24.
    Furthermore, as illustrated in particular in FIGS. 5 and 6, the axial depth P of the cavities 32 is less than a quarter of the axial thickness E.
    Furthermore, the cavities 32 have a length L - considered in an orthoradial direction - as well as a radial width L The length
    BE2016 / 5817
    L of the cavities 32 is, in this example, substantially equal to 15 times its radial width t of said cavities 32.
    It should also be noted that its radial width f of the cavities is less than half the radial height H of the annular tire.
    Using FIG. 3, it can be seen that the axial height H of the one-piece annular bandage 20, considered between two first adjacent orifices 30, is substantially constant over the entire radial thickness E of the one-piece annular bandage. that the first and second annular lateral faces 26, 28 are substantially parallel to one another.
    In this example, the one-piece annular bandage 20 furthermore comprises a plurality of third orifices 30 ', constituting cavities 32' which open into its second annular lateral face 28. More specifically in this example, the first and third orifices 30.30 ' are symmetrical with respect to a plane Q which is orthogonal to the main axis C of the one-piece annular bandage.
    Referring to Figure 5, we see that Its cross section of the one-piece annular bandage 20, considered in a plane R containing the main axis C, has a general quadrangular shape, in this example substantially rectangular, it being specified that the peripheral face interior 22 has a convex shape.
    In the example of FIG. 5, the convex inner peripheral face comprises three annular faces 40,42,44 which are inclined with respect to each other. More specifically, the inner peripheral face 22 comprises a first annular face 40, which is inclined relative to the main axis C, opening towards the first annular side face, a second annular face 42 which is parallel to the axis main C, and a third annular face 44 which is inclined relative to the main axis C, opening towards the second circular lateral face. The second annular face 42 is disposed between the first and third annular faces 40,44. The interest of this configuration will be explained below.
    The one-piece annular bandage 20 further comprises a plurality of first recesses 50 which are formed in the first annular lateral face 26. These recesses open out into
    Its first annular lateral face 26. Said recesses 50 are
    BE2016 / 5817 arranged radially between some of the first orifices and its inner peripheral face 22.
    As can be seen in FIG. 6, the orthoradial length R of the first recesses 50 corresponding to approximately one third of the orthoradial length L of the cavities 32.
    Referring to FIG. 2, it can be seen that the one-piece annular bandage 20 has eight recesses 50 opening into its first annular lateral face 26. More precisely, one out of two cavities 30 is associated with a recess 50. The annular bandage further comprises second reinforcements 50 ′, symmetrical to the first reinforcements with respect to the plane Q.
    The interest of the recesses 50 and 50 'will be detailed below.
    The annular bandage 20 also comprises a plurality of second orifices 60 which open into the first orifices 30 and into its inner peripheral face 22. These second orifices 60 are better visible in FIGS. 3 to 6.
    According to the invention, the first and second orifices 30, 60 are configured to receive adjustment members 70 for the position of the annular tire relative to the cylinder. These adjustment members 70 will be described in more detail below.
    It can be seen that the second orifices 60 are holes 62 which extend radially between the inner peripheral face 22 and the cavities 32.
    It is also noted that the annular tire 20 has a piurality of fourth orifices 60 'constituting holes 62', which are symmetrical to the second orifices 60 with respect to the abovementioned plane Q.
    In this nonlimiting example, the holes 62, 62 ′ have a diameter of the order of 35 mm and extend radially along approximately 80 mm.
    Referring to FIG. 6, it can be seen that Its holes 62 have radial axes Y which are arranged axially between Its first and second annular lateral faces 26,28.
    Referring again to FIG. 2, it is noted that the annular bandage 20 also includes holes 17 making it possible to grasp and move the bandage when it is mounted on its ferrule.
    BE2016 / 5817
    Furthermore, the outer peripheral face 24 of the one-piece annular bandage 20 has a roughness Ra according to ISO standard 4287 which, in this example, is equal to 3.2 μm.
    Referring to FIG. 1, it is understood that the outer peripheral face 24 is in contact with its rollers 16.
    According to the invention, the annular bandage is in one piece. It is therefore a one-piece annular bandage. To do this, the annular bandage is molded in one piece. The first and second orifices 30, 60 as well as the third and fourth orifices 30 ', 60' are then produced by removing material after molding. It is also understood that the first and second recesses 50, 50 'are made by removing material after molding.
    Using FIGS. 7 to 11, it can be seen that the drive assembly 14 also comprises a plurality of first wedges 80 and second wedges 82, visible in particular in FIGS. 7, 8, 10 and 11, which are arranged between the ferrule 18 and the inner peripheral face 22 of the annular bandage. The first and second caies are arranged between the shell and the inner peripheral face of the one-piece annular bandage. After having threaded the annular bandage around the ferrule in the vertical position, a part of the first and second wedges is force-fitted in order to block the bandage relative to the ferrule. More precisely, some of the first and second wedges 80, 82 are arranged between the outer peripheral surface 18a of the shell 18 and the first and third annular faces 40.
    As explained above, the drive assembly further comprises adjustment members 70, 70 ′, visible in FIG. 11, constituted in this example by jack screws, which extend in its holes 62, 62 ′ and which are configured to bear on the peripheral surface 18a of the ferrule 18. The actuation of the jack screws has the effect of displacing the annular tire 20 relative to the ferrule 18 in order to adjust the coaxiality of the main axis C of the annular bandage 20 relative to the axis of the ferrule.
    The drive assembly further comprises locking members 90, 92, visible in FIG. 9, and having the form of blocks, which are welded to the shell and which cooperate with the recesses
    BE2016 / 5817
    50.50 'to maintain the one-piece annular bandage 20 relative to the ferrule 18.
    The ferrule is then pivoted so that its first axis is horizontal. The ferrule is then welded to the cylinder. The first and second remaining wedges 80, 82 are then placed between the third section 44 of the shell and the annular bandage. After ensuring the coaxial axis of the annular tire with the cylinder axis, the first and second shims are welded to the ferrule. Finally, the jack screws are removed.
