Definitions
- the invention relates to a candle filter, consisting of at least one perforated filter element, the outside of the filter element having helically circumferential grooves.
- the filter cartridge consists of a support sleeve made of plastic material, which is inserted into a tubular filter sleeve made of felt material and is closely enclosed by this.
- the support sleeve is perforated for the filtrate drain.
- the support sleeve has a net-like appearance.
- two groups of helically bent bars are arranged so that their slopes run in opposite directions. The bars are connected to each other at the crossing points, resulting in a network-like structure.
- the support sleeve is inserted into a tubular filter sleeve made of non-self-supporting needle felt, the needle felt having such a high degree of rigidity that the filter sleeve has sufficient strength to maintain its shape.
- a disadvantage of such a filter cartridge is that a filter cake built up on the filter sleeve is not supported. There is therefore a risk that the filter cake collapses in the dried, shrunk state. Rinsing the filter cake is then only possible to a limited extent, since the rinsing liquid flows away mainly in the uncovered areas of the filter, while the filter cake lying in the lower area of the filter is no longer flowed through. It is therefore an object of the invention, starting from DE-OS 15 36 928 to provide a filter element for a candle filter, in which the filter cake is sufficiently stabilized even in the dried and shrunk state, so that subsequent rinsing with a solvent can be carried out without problems is.
- the profile of the surface is curved outwards in the shape of a segment of a circle between grooves in an imaginary plane perpendicular to the grooves.
- the area with which the filter cake adheres to the filter element is thereby advantageously increased, and the filter cake is additionally supported against the direction of gravity. Even after drying, i.e. after cracks appear in the filter cake, the filter cake is adequately supported and therefore cannot collapse. A rinse following drying can therefore be carried out without any problems.
- the production of the filter element is cheaper because the outer surface of the filter element consists of a partial surface of at least one helically shaped tube. Stand for inexpensive production of pipes
- a central axis is designed as a linear central tube, the structure of the filter element is additionally stabilized. On the ends of the
- Central tube can be plugged in each case, which close the filter element up and down. During operation, the central tube absorbs the forces that result from the differential pressure. A good support of the filter cake is achieved when the helical circumferential groove has a slope of 5 "to 60 °, the best support is achieved when the helical circumferential groove has a slope of 30 °.
- the manufacture of the filter element can be further simplified if the outer sides of the tubes are connected to one another. In this way, a tube bundle as a coherent part in one step, for. B. be produced by extrusion.
- the filter element is particularly resistant to aggressive chemicals if the filter element consists of a polymeric plastic, preferably polyvinyl difluoride or polypropylene.
- the manufacture of the filter element is further simplified if a plurality of tubes are combined to form a tube bundle and the tube bundle is preferably constructed from tubes of the same diameter.
- the filter element is particularly stable in that the tube bundle is constructed from six tubes.
- the bundle can be summarized from six tubes in the densest packing of the individual tubes.
- the bundle becomes particularly stable when it is constructed from six tubes and a central tube.
- the outflow of the filtrate is further improved in that the filter element has ribs on its outer sides.
- the ribs form further channels through which the filtrate can drain.
- the centrifuging of the filter cake is facilitated in that the outside of the filter element is covered with a stocking-like, preferably elastic, filter fabric. When the filter element is backwashed, the filter fabric swells. The filter cake is thrown off during this movement. If the filter fabric is elastic, it clings to the filter element without creating wrinkles.
- FIG. 1 shows a cross section along the section line I-I in Figure 2 by a filter element for candle filter, which is designed as an integral part.
- Fig. 2 a side view of a
- Filter element for candle filters.
- the filter fabric is removed on the front of the filter element for better clarity;
- a filter element for candle filter which is constructed as an assembly of six tubes and a central tube.
- Fig. 4 a side view of a
- Filter element for candle filters.
- the filter fabric is for better Clearness removed on the front of the filter element.
- Fig. 1 denotes a tube which is constructed from an extrudable material 11 and has seven channels 3, 5 with a circular cross section in its interior. Six winding channels 3 are arranged around a central channel 5 in the densest spherical packing.
- the tube 12 On its outside, the tube 12 has grooves 2 running in a helical shape, between the grooves the perforated outer surface 14 is curved outward in the manner of a segment of a circle. These circularly outwardly curved outer surfaces 14 have ribs 4, which each run parallel to the grooves 2 along the outer surface.
- the outside of the tube is covered with a stocking-like filter fabric 1.
- 1 denotes the state during the filtration, in this case the liquid flows from the outside of the tube 12 into the channels 3.
- 1 ' is the state of the
- Filter fabric called during rewinding.
- the liquid flowing outwards from the channels 3 lifts the filter fabric 1 ' and the filter cake is thrown off.
- Fig. 2 are designated 8 and 9 caps, which limit the filter element down and up, respectively.
- the cap 9 has an opening 15 through which the filtrate is discharged from the central tube 5 to the outside.
- the central channel 5 is expanded into a cup-shaped cavity 13, into which the channels 3 also open.
- the helically curved channels 3 have openings 6, 7 for the filtrate drain, which, depending on the application, can be circular 6 or slit 7.
- the outside of the tube is covered by a filter fabric 1, position 1 shows the condition of the filter fabric during filtration and position 1 'shows the condition during rewinding.
- the filter fabric is fastened to the cap 9 with a sleeve 10.
- the filtrate flows off through the openings 6, 7 into the channels 3, with the build-up of a filter cake on the outer surface of the filter element. from there it is collected via the cavity 13 in the central channel 5 and via the opening 15 from the
- Filter element discharged For backwashing, the flow direction is reversed, the filter fabric swells by the liquid flowing out of the filter element and is detached from the outer surface 14 of the filter element. During this movement, the filter cake is thrown off the outer surface of the filter element.
- Fig. 3 shows a filter element which is constructed as a tube bundle from seven individual tubes.
- six helical, spiral tubes 23 are arranged in the tightest packing around a central tube 25.
- the outer walls of the tubes abut against one another, as a result, grooves 2 are formed on the surface of the filter element and run helically along the outer surface 24 of the filter element.
- the tubes 23 are connected to one another via a welded, melted or adhesive connection 22.
- the outer surface of the tube bundle is covered with a stocking-like filter fabric 1.
- Position 1 shows the state during the filtration, the filter cake collecting in the grooves 2.
- Position 1 ' denotes the position of the filter fabric during the backwashing process, it is then largely lifted off the outer surface 24 of the tube bundle.
- FIG. 4 shows the position of the linear central tube 25. It leads through the cap 9 from the bundle formed by the tubes 23. At the opposite end it extends to a cup-shaped cavity 26 which is delimited by the cap 8.
- the tubes 23 are arranged helically around the central tube 25 and open into the cup-shaped cavity 26. Between the tubes 23, the grooves 22 run along the surface 24 in a helical manner.
- the tubes 23 have openings 6, 7, which are either circular 6 or slot-shaped 7 could be.
- the filter element is covered by a filter fabric 1, which is fixed to the cap 9 by a sleeve 10.
- Position 1 denotes the position of the filter fabric during the filtration process. It lies close to the surface 24 of the filter element.
- Position 1 ' denotes the position of the filter fabric during the backwashing process.
- the filtrate flows out through the openings 6, 7 into the tubes 23, with the formation of a filter cake on the outer surface of the filter element. from there it is collected via the cavity 26 in the central tube 25 and discharged from the filter element via the opening 15.
- the flow direction is reversed, through which from the
- Liquid flowing through the filter element inflates the filter fabric and is detached from the outer surface 24 of the filter element. During this movement, the filter cake is thrown off the surface of the filter element.
