Definitions
- the invention relates to a disk filter for separating liquids from a suspension, in particular a pulp suspension, with 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 liquid-permeable filter discs, the interior of which is in communication with the hollow shaft and arranged between the filter discs Stoffausêtn, wherein the filter discs of several
- At least a plurality of filter elements are fastened via a respective Sektorfuß to the hollow shaft and the Sektorfuß at least a plurality of filter elements is fixed only on one of the two in the circumferential direction of the hollow shaft sides directly to the hollow shaft.
- Such disc filters are used to thicken the suspension and in the
- the hollow shaft is usually connected to a vacuum source.
- On the filter discs is formed due to the pressure difference between the
- Pulp suspension and the interior of the filter discs a nonwoven layer.
- immersing the filter discs in the pulp suspension passes as far as possible only water in the interior of the filter discs and thus the hollow shaft.
- the nonwoven layer is removed during the dipping over scraper and the
- the object of the invention is therefore to ensure a simple and secure attachment of the filter elements.
- this object is achieved in that a non-connected to the hollow shaft side of a sector foot of an adjacent to a directly connected to the hollow shaft side of a sector foot of a filter element
- Filter element is adjacent and directly connected to the hollow shaft side of the sector foot has a fixing agent which presses not directly connected to the hollow shaft side of the sector foot of the adjacent filter element in the direction of the hollow shaft.
- the result is a stable and easy-to-install attachment of the filter elements to the hollow shaft.
- the hollow shaft In order to simplify the manufacture and construction of the hollow shaft, in particular when it accommodates a plurality of channels for fluid guidance, the hollow shaft should consist of several, extending in the axial direction and in the circumferential direction be assembled side by side modules. To minimize the production costs, it is advantageous if the modules each have a flat outer surface, so that there is a polygonal cross-section in the hollow shaft. However, a round outer surface, ie a circular cross section of the hollow shaft is possible.
- the hollow shaft should have a plurality of openings on the outer surface, wherein preferably each filter element is associated with a separate opening.
- Filter element the direct attachment of the filter elements to the hollow shaft in each case at at least two points in the circumferential direction of the hollow shaft side facing 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.
- the fixing agent should advantageously be formed by a setting or pressure element, which is supported on the one hand on a stop of the sector foot and on the other hand on a counter-stop of the adjacent sector foot.
- a setting or pressure element which is supported on the one hand on a stop of the sector foot and on the other hand on a counter-stop of the adjacent sector foot.
- the fixing itself or the stop and / or the counter-stop of the respective sector foot is formed by a, preferably in the direction of the adjacent sector foot reaching fixing.
- assembly or disassembly of the filter elements can possibly be facilitated if at least one fixing arm of two adjacent sector feet is designed to be pivotable. By pivoting away a fixing so the space of movement of a filter element to be dismantled can be released or extended.
- the actuating 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 counterstop.
- the actuating or pressure element can also be formed by a spring.
- the filter elements and thus the filter discs composed thereof have a permeable, preferably perforated, corrugated surface.
- FIG. 1 a variant of a fastening of a filter element 6 on a hollow shaft 3
- FIG. 2 a detailed view of FIG. 1;
- FIG. 3 another variant of the attachment
- Figure 4 another view of Figure 3 and
- Figure 5 a schematic side view of a disc filter.
- the pulp suspension 1 is passed in accordance with Figure 5 via an inlet 17 into the container 2 of the disc filter.
- the container 2 In the container 2 is a horizontally extending and rotatably mounted hollow shaft 3 with a plurality of vertical and axially spaced-apart filter discs 4th
- the filter discs 4 are each formed by a plurality of sector-shaped filter elements 6, which are connected via a respective Sektorfuß 7 with the hollow shaft 3.
- the hollow shaft 3 consists of several, extending in the axial direction and in the circumferential direction 8 juxtaposed modules 1 1, wherein the modules 1 1 each have a flat outer surface.
- each module 1 1 is associated with only one sector foot 7 of a filter element 6 of a respective filter disk 4.
- 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.
- the hollow shaft 3 connected to a vacuum source communicates 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.
- the sector feet 7 of all filter elements 6 are each only on a 9 of the two in
- Circumferential direction 8 of the hollow shaft 3 facing sides directly to the hollow shaft 3 by means of two axially spaced screws 13 attached.
- 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 counter-stop of the adjacent sector foot 7.
- Sektorfußes 7 formed by a reaching in the direction of the adjacent Sektorfußes 7 Fixierarm 15.
- control or pressure element 14 each acts a screw which is screwed through the stopper forming the fixing arm 15 and is supported on the counter-stop of the adjacent Sektorfußes 7. In this way, the actuator or pushes
- Pressure element 14 the counter-stop of the adjacent Sektorfußes 7 in the direction of the hollow shaft 3, so that there is an indirect fixation on the hollow shaft 3 on this side of the sector foot 7.
- each sector foot 7 has two axially spaced apart fixing arms 15 with adjusting or pressure element 14.
- the attachment is very stable.
- individual filter elements 6 easy be replaced.
- only the respective screw 14 of the two fixing arms 15 must be solved.
- the direct attachment of the respective Sektorfußes 7 can be solved.
- the fixing arms 15 are designed here parallel to the outer surface of the modules 1 1 pivotally. By laterally pivoting the fixing arms 15 so the
- Movement margin for the adjacent filter element 6 is released or increased.
- the assembly of the filter element 6 can then be made analogously in reverse order.
- the fixing arm 15 is mounted so that it can pivot away from the sector base 7 in the radial direction, then the function of the adjusting or pressing 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.
- serves as a control or pressure element 14 each have a screw which is screwed through the stopper forming the fixing arm 15 and on
