Definitions
- the invention relates to a device for cleaning the knife ring of a Knife ring chipper.
- Chipper of this type are described in DE 32 47 629 C1. They include in single a knife ring with a wreath of knife packets as well as two these bearing support rings, each at the ends of the knife packages are arranged. Each knife package has a knife which is against the Radial direction is inclined and the cutting edge points inwards. It is Furthermore, a rotor is provided, which is arranged coaxially to the blade ring and of this is enclosed. Each knife package includes a knife carrier and a clamping plate sandwiching the knife between them.
- the blades of the knife ring are subject to relatively high wear. she must therefore be reground at certain intervals. In addition, it comes to a clamping or caking of chips or debris from chips in the gaps between the knife carrier and the knife ring or the knife and the clamping plate or Knife package and the carrying rings. These deposits must be eliminated to ensure proper working of the chipper. This especially applies when using grinding machines.
- the invention has for its object to provide a device with the knife rings are cleaned in a more rational way than ever since can. This object is solved by the features of claim 1.
- a device which comprises a support means for Receiving the knife ring to be cleaned, further comprising a housing, Furthermore, a drive to a circulation of the blade ring to be cleaned cause its own axis, and finally elements that are on the Acting knife ring, such as cleaning brushes and nozzles for Application of hot steam, hot or cold water and others Cleaning media. This leaves a polluted and with deposits afflicted knife ring with minimum personnel expenditure quickly and thoroughly clean.
- the knife ring chipper shown in Figure 1 comprises a fixed one Knife ring 1.
- the knife ring encloses a rotor 2, which on a Rotor shaft 2.1 is seated. Knife ring 1 and rotor 2 are coaxial with each other arranged.
- the knife ring 1 is permanently installed in a housing 3.
- the Housing 3 has an inlet 3.1 for supplying wood chips, Further, a chip outlet channel 3.2, which encloses the knife ring.
- FIG. 2 shows three knife packages as part of the knife ring 1 shown.
- Each knife package has a knife 1.1. This is between a knife carrier 1.2 and a clamping plate 1.3 clamped.
- each Knife package is in the present case with a so-called stick knife 1.4 provided.
- the cleaning device shown in Figures 3 and 4 shows dashed, and thus very schematically, a knife ring 1.
- the cleaning device 10 comprises a carrying device.
- the carrying device comprises two carrying rollers 11.1, 11.2, on which the knife ring 1 can roll.
- the carrying roller 11.2 is of a Motor 11.3 drivable.
- a housing 12 can be seen.
- the housing 12 has two end walls on 12.1 and 12.2 - see Figure 4.
- the end wall 12.2 can be opened.
- a carriage 13 serves to carry and retract the Knife ring 1 in the interior of the housing 12 on the support rollers 11.1, 11.2.
- trailer rollers can be provided. These would then be located in the upper part of the device 10, and Although not outside of the knife ring 1 but within, in order to Attack inner circumference.
