Definitions
- the most common method for separating solids from a slurry consists in filtering the slurry with the help of more or less fine-pored filter media.
- a major disadvantage this method is that the pores of the filter media add relatively quickly with solid particles from the slurry, so that a significant hydrostatic pressure is applied to the slurry in order to get any liquid through the To get filter media through. That hydrostatic pressure in turn leads to the fact that the particles are only firmer in the Pores of the filter medium are pressed, reducing the filter performance is deteriorated further.
- a filter device which Starting point of the present invention according to the preamble of claim 1 and contains the tubular filter elements, consisting of perforated tubes with on the outside attached filter media.
- the filter elements are on one of a circular ring formed tube and arranged into a cage connected to each other and form a rotor which in one the container to be filtered around liquid and after is drained outside.
- the invention has for its object a filter device of the aforementioned type, with which a separation of Solid particles from a slurry in continuous or quasi-continuous Operation is possible, and being an increased Performance can be achieved without a too high hydrostatic on the turbidity Pressure must be applied.
- the filter device 1 consists of FIGS. 1 and 9 a boiler 4 consisting of an upper shell 4o and a lower one Shell 4u, which is approximately in the middle of the boiler 4 with the help of the damage formed upper and lower flanges 5o or 5u are releasably connected to each other.
- the end walls 6o and 6u of the boiler 4 are arched lenticular.
- the diameter of the Boiler 4 is approximately 1.3 times the height of the jacket sections of the shells 4o and 4u.
- the a filter element group is assigned to the upper shell 4o and contains filter elements, which are designed as a disk stack 7o are on two circles on an upper support structure 8o are attached.
- the upper support structure 8o is on an upper one Hollow shaft 9o attached to the upper end wall 6o Shell 4o penetrates and is rotated by an upper motor 10o is relocatable.
- On the upper hollow shaft 9o are adjacent upper end wall 6o also the blades 11o of an upper turbine attached, which belong to the upper support structure 8o.
- a lower filter element group is comparable to the lower shell 4u assigned, consisting of filter elements that likewise disk stack 7u are different on two concentric circles Diameters are arranged and of a lower supporting structure 8u are held, which are attached to a lower hollow shaft 9u is.
- the lower hollow shaft 9u penetrates the lower end wall 6u of the housing shell 4u and is from a lower motor 10u driven opposite to the direction of rotation of the upper hollow shaft 9o.
- On the lower hollow shaft 9u are close to the lower one End wall 6u also the blades 11u of a lower turbine attached, which belong to the lower support structure 8u.
- the upper filter element group surrounds the lower one Filter element group.
- the sludge chamber is via a feed line and a pump (both shown important) 14 in the boiler 4, in which the filter element groups and their support devices are located with a slurry feedable.
- a feed line and a pump (both shown important) 14 in the boiler 4 in which the filter element groups and their support devices are located with a slurry feedable.
- the filter elements each exist from a stack on a common support tube with mutual Distance between filter disks 307o and 307u.
- the filter discs deserve a precise description. This should be given with reference to FIGS. 3 and 4.
- FIG. 2 A schematic radial sectional view of the filter element arrangement with one part within the filter device of FIG. 1 the supporting structure is shown in FIG. 2.
- Each filter element consists of a stack of filter discs, 3 of which two filter disks 307o are shown are.
- the filter disks 307o of a stack are of one Support tube 308o held, with spacers 309 and sealing rings 310 are inserted, the adjacent filter disks 307o keep at a distance from each other.
- the filter discs 307o have each have a hollow interior 311 (see also FIG. 3) on, which by at least one associated breakthrough 312 in Support tube 308o is drained into this.
- the support tubes are at one end over the support bracket holding them completely comparable to the filter candles already described dewatered, see also Fig. 3, upper section of the Drawing.
- the embodiment 4 shows a possible embodiment of the interior Construction of the filter discs 307o or 307u.
- the embodiment 4 shows two close-meshed lattice structures 313 from a coarse-mesh lattice structure 314 to one another Kept clear.
- the close-meshed lattice structures 313 are covered on its surface by filter cloths 316, the edge the filter disc on an axially separable clamping ring 315, 317 are held under clamping of O-rings 318.
- the Parts 315 and 317 of the clamping ring have an elastic circumferential closure on to the clamping ring to exchange the To be able to open filter cloths 316.
- Near the support tube 308o or 308u are the filter cloths 316 due to the O-rings already mentioned 310 captured and sealed.
- a rigid, porous, disc-shaped hollow body are used on the edge the filter cloths are fixed by a potting compound that a cavity between a ring and the edge of the hollow body fills. It is also possible to form the filter cloth in one piece, so that the top and bottom of a rigid, porous, disc-shaped hollow body covers, so that an attachment of the filter cloth only in the area of the support tube is.
- the construction with filter discs has the advantage that a Sub-group filter elements so close together can be mounted that in the presence of a mutual axial offset the filter discs of the one filter element in the spaces between the filter discs of the penetrate adjacent filter element. This is in Fig. 1st and 2 clearly recognizable.
- FIG. 5b shows, by twisting of the brackets on their supporting structure and - because of the cranking of the Holding the ends of the support tubes 309o or 309u - by twisting of the filter elements on their brackets the distance the filter element groups have to change from each other.
- the Fig. 5b shows solid lines an arrangement that a wide space Z results, and in dashed lines Lines an arrangement that a narrow space z to Consequence. You can also in the circumferential direction of the space seen alternating distances to provide the pulsation effect within the cloudiness that runs through the mutual of the filter element groups results to vary, in particular to reinforce.
- FIGS. 1 to 4 A variant of the embodiment of FIGS. 1 to 4 is in Fig. 6 shown.
- the filter discs 307o and 307u each at an angle of inclination with respect to the axis of the respective support tube 308o and 308u, respectively with alternating positive and negative angles of inclination, whereby these angles of inclination all with respect to a common one Axial plane are defined.
- the one on both sides of a filter disc neighboring filter disks are thus mutually exclusive parallel.
- angles of inclination can be selected differently. she are in the illustrated embodiment for the filter discs 307u, which are closer to the axis of rotation (not shown) larger, i.e. deviate more from the perpendicular to the support tube axis Arrangement from than the distant from the circumferential axis Filter discs 307o. This will make the different Radial components within the turbid flow caused by the Turbines (not shown) are invoiced carried.
- the filter elements of a subgroup can be used as for Example of Fig. 1 can be arranged so that the filter discs two filter elements overlap each other, the arrangement is taken so that seen from the tube axis mutually approaching sections of second upstream filter disks a filter candle in the space between those seen from the pipe axis that are distant from each other Sections of two filter disks of the neighboring, downstream Immerse the filter candle.
- Fig. 6 this is very much illustrated clearly. This creates a nozzle effect generates the turbidity into the crevice that downstream located filter disks with the upstream Form filter discs. Upstream they are radially wider internally arranged filter cartridges, while the downstream filter candles arranged radially further outward.
- the orientation of the openings, each two filter discs form, can be such that these are directed into the circulation center are, but you can also choose the orientation so that the through the circulation of the filter element groups around the circulation center generated inflow with turbidity in the narrowing gap occurs between two filter disks, i.e. the filter discs are twisted in relation to the aforementioned orientation.
- the Choice of setting depends on the type of turbidity and the circulation speeds of the filter element groups determined thereby and the strength of the pump flow.
- FIG. 7 are on a support tube 508 radially protruding holding tubes 506 attached via connection brackets 573.
- On every holding tube 506 is a package of filter disks arranged parallel to one another 507 attached, in the manner of the filter disks of FIG. 3 and 28 can be executed. Comparable to the embodiment 3, these filter disks 507 are at a distance held and sealed to the holding tube 506.
- the filter discs 507 are over the support tubes 506 and connection brackets 573 drained into the support tube 508, which in turn over the Support structure is drained.
- a middle support tube rotates in the axis of rotation of the support structure, the other support tubes run on circular orbits around this axis.
- the holding tubes can be Adjust 506 on the support tubes 508 so that two neighboring ones Filter element pairs, each consisting of two packets of filter discs 507 exist on their associated support tubes 506, in mutual Distance can be changed. It is also possible to provide the individual packages with cranked feet and heads. Then the two packages of a pair can be in mutual Distance can be adjusted.
