Further embodiments of the invention are characterized in the claims. The invention is explained in more detail in the following description and the drawings which illustrate exemplary embodiments.
- FIG. 1 shows a section through a known fastening of a drainage element to the pressure plate of a fruit press
- FIG. 2 shows a section through a filter casing according to the invention and an associated holding body for explaining the mounting on the pressure plate of a fruit press
- FIG. 3 to Fig. 14 embodiments of the filter cover with an inventive annular bead in partial section.
- FIG. 2 shows on the left a filter cover 26 similar to the type already shown and explained in FIG. 1.
- the circumference and diameter of the filter cover 26 can be enlarged by stretching as a result of production by means of a knitting process.
- an elastic ring 29 consisting of a plastic mass is fastened around the ring 29 by turning around the inside of the end 23 of the filter sleeve 26.
- the end 23 is attached to a further back region of the filter sleeve 26 by sewing.
- the elastic ring 29 is clamped between an outer sleeve 46 and an inner sleeve 48. 1.
- the inner sleeve 48 acts as a rigid part instead of the elastic cuff 8 according to FIG. 1. It has a neck 47 to support the end of the filter sleeve 26 from the inside and is provided with a transverse pin 11 ′ which penetrates the outer sleeve 46 and the drainage core 4. axially fixed.
- the inner diameter 31 of the filter sleeve 26 is significantly larger than the diameter 32 of the drainage core 4. This can prevent the filter sleeve 26 from shrinking on the drainage core 4. As shown in Fig. 2, the inner diameter 31 of the filter sleeve 26 is significantly larger than the diameter 32 of the drainage core 4. This can prevent the filter sleeve 26 from shrinking on the drainage core 4. As shown in Fig. 2, the inner diameter 31 of the filter sleeve 26 is significantly larger than the diameter 32 of the drainage core 4. This can prevent the filter sleeve 26 from shrinking on the drainage core 4. As shown in Fig. 2, the inner diameter 31 of the filter sleeve 26 is significantly larger than the diameter 32 of the drainage core 4. This can prevent the filter sleeve 26 from shrinking on the drainage core 4. As shown in Fig. 2, the inner diameter 31 of the filter sleeve 26 is significantly larger than the diameter 32 of the drainage core 4.
- Diameter 31 of the filter sleeve 26 increased by beating around the elastic ring 29 at its end. For assembly, however, it is necessary to insert this end through the narrowest opening of the outer sleeve 46, the diameter of which is at most equal to the outer diameter of the filter sleeve corresponding to the diameter 31. This is possible because the ring-like bead 23, 29 is designed to be deformable in a suitable form.
- Fig. 3 shows the use of an inventive
- Filter cover 6 ' with a fastening device known per se, as has already been explained in relation to FIG. 1. Components corresponding to FIG. 1 bear the reference numerals already given there on this fastening device. 3, as in the embodiment according to FIG. 2, the filter 6 'is wrapped around the 0-ring 9 from the inside to the outside. The end 33 of the filter sleeve 6 'is simply fastened by means of a seam 24 to a further back region of the filter sleeve 6' by sewing. As a result of the production by means of a
- the circumference of the filter 6 ' is stretchable by the knitting method, and can therefore, as shown in FIG. 3, adapt to the enlarged diameter of the elastic cuff 8 in the region of the 0-ring 9.
- FIG. 4 to 14 show embodiments of the filter sleeve with a ring-like bead according to the invention in partial section.
- the filter sleeve 26 is wrapped around an elastic ring 29 from the inside to the outside.
- the end 33 of the filter sleeve 26 is not hammered in again, but is simply fixed by means of a seam 24.
- the end 43 of the filter sleeve 26 is also simple with a seam 24 attached, but the end 43 is here from the outside in around the ring 29.
- the ring can also consist of a comparatively hard elastic material, as long as its
- Deformability only allows pushing through the opening of the outer sleeve 46, as described for FIG. 2.
- a material is provided in the design of the ring 59 according to FIG. 6.
- the cross section of the ring 59 is selected to be rectangular, and its shape can essentially only be changed in the area between the circle and the oval.
- the end 53 of the filter sleeve 26 is fastened in the area 54 by sewing or by ultrasound welding to the area of the filter sleeve 26 further back.
- groups of several rings can be used instead of the rings 9, 29, 59 of FIGS. 2 to 6.
- 7 shows a group of two elastic rings 68, 69 which are wrapped together by the filter sleeve 26.
- the fastening of the end 33 of the sheath 26 in the zone 24 corresponds to that according to FIG. 4.
- rope rings 79 according to FIG. 8 or wire helices 89 according to FIG. 9 can also be used as spring rings. If it is desired to dispense with sewing or welding when fastening the end 33, 53 of the filter sleeve 26, a further outer ring 19 according to FIG. 10 or 90 according to FIG. 11 can also be used for this.
- the end 93 or 92 of the filter sleeve 26 is expediently formed so long that it can protrude to the right over the end of the filter sleeve 6 'when attached to the press according to FIG. 3. Possible slight tightening of the filter sleeve 26 then does not lead to a loss of the holding effect.
