Definitions

  • the invention relates to a clothing carrier according to the preamble of Claim 1, on a special use as well as on this clothing carrier using grinding disc.
  • Set carriers of this type are used to hold sets with which in water Suspended fiber is to be processed mechanically. That is above all Grinding paper fibers, dispersing impurities and fibers and that Unstuck, meaning the dissolving of fiber agglomerates. When grinding in refiners and when deflaking, the suspension has a solids content of about 2-8%. at Machines for higher consistency are called e.g. of high consistency mills, Dispersers or kneaders.
  • Trimmings are the working tools that are used in appropriate processing machines are to be installed. If they are subjected to heavy wear, they must be in certain intervals can be replaced. Many sets point to the on the Working surfaces lying on the front are webs and grooves, which is why one also from "Knife trimmings" speaks. Other sets have the shape of toothed rings there.
  • EP 0 922 495 A1 describes a process for producing special sets known that differ from the usual sets in that they are made of separately manufactured parts, namely a base body and a Editing element to be joined. Between these parts is a elastic binder used. These are particularly complex Special sets that do not consist of a single material.
  • Machines equipped with this type of set have at least one Rotor and at least one stator with either disk-shaped or conical Areas on which the trimmings are attached with their back so that they each have a relatively large contact area with the rotor or stator.
  • the rotor or stator thus serves as a clothing carrier or contains one or more Clothing support.
  • the trimmings are wearing parts, which are therefore easy to wear must be replaced.
  • the object of the invention is to provide clothing carriers of the type mentioned design that the volume when operating the processing machines is essential is reduced. This purpose should also be achievable when using conventional sets be, especially those made entirely of metal.
  • a clothing carrier designed according to the invention reduces the noise development to one tolerable size without having to change the actual sets have to.
  • a toothing on the contact surfaces of the Vibration damping layer set may be advantageous, e.g. about accuracy to increase the positioning.
  • Fig. 1 shows a side view of a clothing carrier 1 with assembled clothing 5.
  • To Processing the suspended fiber material is with the front of the set various long strips 7 provided. The shorter one is cut.
  • the Strips of the processing element 2 protrude, whereby a known per se Grinding set is created, which is also known as a knife set.
  • the set 5 is with its back by means of fastening screws 4 passed through holes 6 in a holding plate 3 releasably attached.
  • This holding plate 3 is part of the clothing carrier 1st
  • vibration-damping layer 2 is located between the holding plate 3 and a metallic base body in the form of The rotor disk 8, which is driven by the shaft 9, is located vibration-damping layer 2. It is glued on both sides and prevents the Operation on the trimmings generated noise transmitted to the rotor as structure-borne noise becomes.
  • the non-illustrated counter set (usually a stator set) is also on a clothing carrier provided with a vibration-damping layer to fix.
  • the rotor and stator are rigid in themselves and are defined by at least one Sliding seat pressed against each other.
  • the set 5 fastened in this way consists of a uniform material, e.g. made of chrome steel. Such trimmings can vary depending on Alignment of the strips 7 in operation can be very loud if they are with the metallic Base body are in direct contact.
  • FIG. 2 shows a top view of similar sets 5 as in FIG. 1 with the partially concealed one Set carrier 1.
  • This illustration is also only schematic.
  • the trimmings have that Form of circular ring elements. They in turn wear lasts 7, which are straight here and for Are of different lengths. Curved strips are also conceivable.
  • Layer 2 The holding plate 3 and the rotor disk 8 are drawn partially uncovered and as a result visible. In the holding plate 3 one recognizes one of the threaded holes 6 'for the Fixing screws 4.
  • the clothing carriers shown in Fig. 3 are intended for installation in a disperser.
  • the Sets used in such a machine are known to have axial interlocking concentric rows of teeth 10.
  • the stator 11 can also be seen, which also has a vibration-damping layer 2 and has a holding plate 3.
  • Deflacers are also provided with sets, their Front contains a number of interlocking rows of teeth. They are hydraulic conditions in de-stipplers and dispersers are different, however the application of the invention is essentially the same. So this is just about an exemplified form of toothed ring sets, as used in dispersers or delipers can be used.
  • the fastening screw 4 is not in anchored to a holding plate but directly in the rotor disk 8. That is less complex, and the layer 2 is less stressed by peripheral forces. It exists but there is a risk that the fastening screws 4 will transmit sound. This can be done with vibration-damping washers 13 and bushings 14 in the Screw holes 6 can be remedied.
