Definitions
- the invention relates to a disc filter hollow shaft for a disc filter for the separation of liquids from a suspension, in particular one
- Pulp suspension with a container for receiving the suspension, in which the hollow shaft extends horizontally and is rotatably mounted, wherein a plurality of axially spaced filter discs are mounted perpendicular to the hollow shaft and the interior of the filter discs with the interior of the hollow shaft in
- 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 by scraper on emergence and the
- the liquid consists of a single or a group of
- the object of the invention is therefore to reduce the expense, at least for the production, but possible for assembly and maintenance in such hollow shafts.
- the object has been achieved in that the hollow shaft consists of several modules.
- the modular design simplifies the manufacture and assembly significantly.
- the selection of the modules makes it easier to adapt to the specific conditions and requirements.
- the modules can also be made and offered from different materials, such as cast aluminum, plastic or stainless steel.
- At least two modules preferably all modules, should be releasably connected to one another.
- the modules may be advantageous for the modules to extend axially over all
- Filter discs or extend over only a portion of the filter discs.
- the modules can extend only over a portion of the circumference of the hollow shaft.
- the modules extend axially over only a portion of the filter disks, it may also be advantageous if the modules extend over the entire circumference of the hollow shaft.
- Connection elements can facilitate or facilitate the attachment and adjustment of individual or a group of modules.
- connection of the modules can be done by welding, but preferably by clamping or screwing.
- connection elements can be formed by axially extending between the modules and radially oriented baffles and / or extending perpendicular to the axis and radially oriented guide ribs.
- modules it is advantageous if these are each formed on the outer circumference of the hollow shaft of a perforated profile sheet, wherein the profile sheet merges with advantage at least one end in a radially inwardly angled support plate, which is supported radially inward.
- the support plate is connected to a support plate of another module and / or the axis and / or a connection element.
- the production and assembly can be simplified if they preferably consist of separate circular sectors. This in turn allows each module of the hollow shaft to assign a circular sector of the filter disk, which further simplifies the construction, since the contact area between the circular sector and the module can be flat.
- the liquid can be passed over the filter discs and a perforation of the profile sheet or the modules in a channel formed by the modules to the outside. Regardless of the structural design of the modules, it is advantageous if the modules form one or more channels for transporting the separated liquids to at least one end of the hollow shaft.
- the container is divided and contains different suspension and / or the suspensions of the sections are to be dehydrated to different degrees.
- At least one module should have at least one channel which extends only over an axial section of the hollow shaft and is preferably guided only to one end of the hollow shaft. In this way, the separated
- Liquids of a portion of the container can be targeted.
- the throughput in a channel is to be limited, this is possible because at least one module has an axially extending over the channel and
- FIG. 1 shows a schematic cross section through a disk filter
- Figure 2 is a partial plan view of this
- Figure 3 a view of a partially mounted hollow shaft
- Figure 4 a view of a fully assembled hollow shaft.
- the pulp suspension 1 is passed in accordance with Figure 1 via an inlet 1 1 in the container 2 of the disc filter.
- the container 2 In the container 2 is a horizontally extending and rotatably mounted hollow shaft with a plurality of axially spaced-apart filter discs.
- the filter discs 3 are formed by two disc-shaped, water-permeable filter elements, which limit the interior of the filter disc 3.
- the channels of the hollow shaft connected to a vacuum source are in each case in communication with the interior of one or more filter disks 3.
- the nonwoven layer forming on the filter elements is deposited after the
- the fabric outlets 12 are each between two adjacent filter discs 3, as shown in Figure 2 can be seen.
- the filter discs 3 are made of several separate, circular sector-shaped
- Suspension level are arranged as close to the hollow shaft and extend over 40 to 60% of the radius of the filter discs 3.
- the limitation of the channel between the filter disk 3 and the fabric outlet 12 to a region located radially as far as possible inside reduces the axial load on the filter disks 3 and improves the mass transfer in the container 2.
- the hollow shafts which are shown in detail in particular in FIGS. 3 and 4, consist of a plurality of modules 4 which extend axially over all the filter disks 3, but only over a portion of the circumference of the hollow shaft in the circumferential direction.
- the modules 4 are mounted on a central axis 5, wherein all modules 4 are detachably connected to each other and / or with the axis 5, in particular screwed. Furthermore, the axis has 5 connection elements 6,7, which facilitate the assembly of the modules 4 and improve the stability. For this purpose, the
- baffles 6 extending and radially aligned baffles 6 and formed by perpendicular to the axis 5 and radially oriented guide ribs 7.
- the modules 4 for forming bilateral support plates 9 perpendicular to the axis 5 has an approximately U-shaped cross-section.
- the starting from the profile sheet 9 radially inwardly angled support plates 9 serve to support on the axis 5 and the connection with a support plate 9 of an adjacent module 4 and / or the axis 5 and / or a connecting element 6.7.
- the liquid absorbed via the filter elements of the circular sectors 10 is thus conducted via the perforation of the profiled sheets 8 into the interior of the modules 4.
- the modules 4 in turn are designed as axially extending channels, which dissipate the liquid from the hollow shaft.
- the liquid of certain circular sectors 10 and / or filter discs 3 can be conducted separately via certain modules 4 to the outside. This separation can be advantageous if the collected liquids have different qualities.
- the modules 4 can also be a perpendicular to the axis 5 extending
- the throughput in a channel is to be limited, this is possible, as can be seen in FIG. 4, via a limiting element 13.
- the limiting element 13 extends axially along the channel and is arranged radially inward in the channel. In this way, the flow cross section in the channel can be made variable, especially when the limiting elements 13 are interchangeable.
