    DISC FILTER
    The invention relates to a disc filter for separating liquids from a suspension, in particular a pulp suspension, comprising a container for receiving the suspension, a horizontally extending in the container and rotatably mounted hollow shaft, a plurality of vertically mounted on the hollow shaft, axially spaced apart and flüs¬ sigkeitsdurchlässigen filter discs whose interior communicates with the hollow shaft and between the filter discs arranged Stoffausläufen, wherein the filter discs are composed of several annular sector-shaped filter elements, at least a plurality of filter elements are fixed via a Sektorfuß on the hollow shaft and the Sektorfuß zu¬ at least a plurality of filter elements only on one of both sides pointing in the circumferential direction of the hollow shaft side is fixed directly to the hollow shaft.
    Such disc filters are used for thickening of the suspension and in the Papierindust¬rie especially for pulp recovery.
    For this purpose, the hollow shaft is usually connected to a vacuum source. Due to the pressure difference between the pulp suspension and the interior of the filter disks, a fleece layer forms on the filter disks. When immersing the filter discs in the pulp suspension reaches as far as possible only water in the interior of the Filterschei¬ben and thus the hollow shaft.
    The nonwoven layer is removed during the dipping over scraper and passed to the appropriate material outlet or sprayed with water in the fabric outlet.
    In this case, the assembly of the circular sector-shaped filter elements often problems. While a secure attachment speaks for as many and comprehensive Befestigungsi¬ agent, which is the demand for a quick and easy disassembly counter. In addition, if possible, the replacement of individual filter elements should be simplified.
    The object of the invention is therefore to ensure a simple and secure attachment of Fil¬terelemente.
    According to the invention this object is achieved in that adjacent to a directly connected to the hollow shaft side of a Sektorfußes a filter element not adjacent to the Hohlwelleverbundene side of a sector foot of an adjacent filter element and directly connected to the hollow shaft side of the sector foot has a fixing agent, which presses the side of the sector base of the adjacent filter element not directly connected to the hollow shaft in the direction of the hollow shaft.
    In this way, only one side of the sector foot must be verbun¬den directly to the hollow shaft, which significantly reduces the cost of assembly and disassembly. At the same time, however, the fixing means of the adjacent sector base ensures fixing of the side of the sector bottom, which is not fastened directly to the hollow shaft.
    As a result, a stable and easy-to-install attachment of Fil¬terelemente results on the hollow shaft.
    In addition, the replacement of individual filter elements is thereby considerably simplified. For this purpose, only the fixing means to the adjacent sector feet and then the direct connection of the filter element to be replaced with the hollow shaft must be solved. The resulting, exclusively direct attachment of a neighboring sector foot is sufficient in the assembly or disassembly phase for stabilization completely.
    In order to simplify the manufacture and construction of the hollow shaft, in particular when this plurality of channels for fluid guidance, simplify the hollow shaft of several, extending in the axial direction and arranged circumferentially next to each other
    Modules are composed. In order to minimize the production costs, it is advantageous if the modules each have a flat outer surface so that the hollow shaft results in a polygonal cross-section. However, a circular outer surface, i.e. a circular cross section of the hollow shaft, is also possible.
    To allow in this case a safe and simple connection with the filter elements, only one sector foot of a filter element of a respective filter disk should be attached to the modules.
    Accordingly, in a planar design of the outer surface of the modules namely also the contact surface of the Sektorfußes with the hollow shaft can be designed flat, which has a positive effect on its production and construction.
    To achieve a safe and simple connection between the hollow shaft or a channel in the hollow shaft and the interior of the filter elements attached thereto, the hollow shaft should have a plurality of openings on the outer surface, preferably with a separate opening associated with each filter element.
    Since a direct attachment only one side of the Sektorfußes vorgese¬hen on the hollow shaft, should for secure fixation of the sector foot and thus the filter element direct attachment of the filter elements to the hollow shaft respectively at least two points in the circumferential direction of the hollow shaft facing side of the respective Sector foot done.
    A particularly simple and stable form of attachment results when the direct attachment of the filter elements to the hollow shaft via screws.
    Furthermore, the fixing should advantageously be formed by a control or pressure element, which is supported on the one hand to a stop of the sector foot and on the other hand to a counter-stop of the adjacent Sektorfußes.
    Depending on the type and shape of the fixative or on the shape of the sector feet it may be advantageous if the fixative itself or the stop and / or the Gegenanschlschlag of the respective sector foot is formed by a, preferably in the direction of the adjacent sector foot reaching fixing ,
    In this case, assembly or disassembly of the filter elements can be facilitated under circumstances, if at least one fixing of two adjacent sector feet is pivotally executed. By pivoting away a fixing arm, the movement space of a filter element to be dismantled can thus be released or expanded.
    In order to easily and safely build an adjustable voltage between the stop and counter stop, the adjusting or pressure element should each be formed by a screw which is screwed through the fixing arm forming the stop and is supported on the counter-stop.
    Alternatively or additionally, the actuating or pressure element but also be formed by a spring.
    For the stability of the filter discs, it is beneficial if the filter elements and thus the filter discs composed thereof have a permeable, preferably perforated, corrugated surface.
    The invention will be explained in more detail in two embodiments.
    In the accompanying drawing: FIG. 1 shows a variant of a fastening of a filter element 6 on a hollow shaft 3; FIG. 2: a detailed view of FIG. 1; Figure 3: another variant of the attachment; FIG. 4 shows another view of FIG. 3, and [0029] FIG. 5 shows a schematic side view of a disk filter.
    The pulp suspension 1 is passed in accordance with Figure 5 via an inlet 17 into the container 2des disc filter. In the container 2 is a horizontally extending and drehier¬bar mounted hollow shaft 3 with a plurality of vertical and axially spaced apart filter disks 4.
    The filter discs 4 are each formed by a plurality of sector-shaped Fil¬terelementen 6, which are each connected via a Sektorfuß 7 with the hollow shaft 3.
    To reduce the production costs, the hollow shaft 3 consists of several, inaxial direction extending and circumferentially 8 juxtaposed Modu¬ len 11, wherein the modules 11 each have a flat outer surface.
    This in turn allows a simple construction of the Sektorfußes 7 in the form of a flange with a flat contact surface to the outside of the respective module 11 out. Therefore, only one sector foot 7 of a filter element 6 of a respective filter disk 4 is assigned to each module 11.
    The filter elements 6 have an interior, which communicates via a separate opening 12 of the hollow shaft 3 with a channel in the same for fluid guidance. The interior of the filter elements 6 is bounded by two perforated corrugated sheets.
    In order to be able to remove the water from the suspension 1, the hollow shaft 3 connected to a vacuum source is in communication with the interior of the filter disks 4, in particular the filter elements 6.
    The nonwoven layer forming on the outside of the corrugated sheets of the filter elements 6 is conveyed from the suspension 1 into the stock outlet 5 after emergence.
    In order to simplify the assembly and disassembly of the individual filter elements 6 unddennoch to ensure a stable attachment to the hollow shaft 3, the sector feet 7aller filter elements 6 are each only on a 9 of the two in the circumferential direction 8 of the hollow shaft 3weisenden sides directly to the hollow shaft. 3 secured by means of two axially spaced screws 13.
    However, a side of a sector base 7 of an adjacent filter element 6 which is not directly connected to the hollow shaft 3 adjoins a side 9 of a sector foot 7 of a filter element 6 which is screwed directly to the hollow shaft 3.
    This allows a bilateral, simple and stable fixation of each Sektorfußes 7 characterized in that the screwed directly to the hollow shaft 3 page 9 of Sektorfußes 7 has a fixing agent 10 which is not directly screwed to the hollow shaft 3 side of Sektorfußes 7 desbenachbarten filter element. 6 towards the hollow shaft 3 presses.
    The fixing means 10 may in this case be formed by a setting or pressure element 14, which is supported on the one hand on a stop of the sector foot 7 and on the other hand on a counterbore of the adjacent sector foot 7.
    In the embodiment shown in Figures 1 and 2, the stop of Sektorfußes7 is formed by a reaching in the direction of the adjacent Sektorfußes 7 fixing arm 15.
    As a control or pressure element 14 each acts a screw which is screwed through the stopper forming the stop 15 and is supported on the counter-stop of the adjacent sector foot 7. In this way, the adjusting or pressing element 14 presses the counter-stop of the adjacent sector foot 7 in the direction of the hollow shaft 3, so that an indirect fixation on the hollow shaft 3 results on this side of the sector foot 7.
    To perfect each sector foot 7 has two axially spaced apart Fixierarme 15 with actuator or pressure element 14. Thus, the attachment is very stable. On the other side as well as individual filter elements 6 can be easily replaced. Hierzumuss only the respective screw 14 of the two fixing arms 15 are solved. Subsequently, the direct attachment of the respective Sektorfußes 7 can be solved.
    In order to simplify assembly and disassembly of the filter elements 6 even further, the fixing arms 15 are here designed to be pivotable parallel to the outer surface of the modules 11. By seitli¬ swiveling away the fixing 15 so the range of motion for the adjacent filter element 6 can be released or increased.
    The assembly of the filter element 6 can then be carried out analogously in the reverse order.
    If the fixing arm 15 is mounted wegschwenkbar in the radial direction of the Sektorfuß 7, the function of the actuating or pressure element 14 can be taken over by the corresponding screw 13. When tightening the respective fixing arm 15 is pressed in the direction of the counter-attack of the adjacent Sektorfußes 7 here.
    In the embodiment according to FIGS. 3 and 4, the stop and counterstop of the respective sector foot 7 for the adjusting or pressing element 14 are each formed by a fixing arm 15, 16 extending in the direction of the respectively adjacent sector foot 7.
    Again, each serves as a control or pressure element 14, a screw which is screwed by den, forming the stop fixing arm 15 and is supported on the counter-stop of the other fixing arm 16.
    To remove a filter element 6 is here just as the adjusting or pressure element14 to adjust. Subsequently, the corresponding direct connection of the filter element 6 to the hollow shaft 3 can be achieved.
