Debris removal device for peat / granulation machine with matrix plate

The invention relates to a debris removal device for a peat / granulation machine with a matrix plate, in which the peat 5 is pressed by a transfer screw along a pipe towards the matrix plate and further through the associated holes to provide a compact.

10 Peat peat / granulation machines produce compacts that withstand rain when the surface dries. Machines using a matrix sheet mainly produce a small diameter compact, granule. The problem with these machines is the clogging of the holes in the matrix plate and often also the formation of a large garbage cake Ib, which cannot be pressed through the holes but remains rotated with the screw against the matrix plate. One debris remover developed to solve the problem uses a debris pocket made in the feed pipe, which is a space protruding from the screw space where wood and other debris is desired to collect. This pocket is also fitted with a lid from which the accumulated mass can be removed.

The object of the present invention is to provide a new and more efficient garbage disposal device. The main features of the invention appear from the appended claim 1.

In the arrangement according to the invention, the lid guides the waste mass rotating against the matrix plate outwards. The cover can, of course, only be kept open inwards if the position of the screw so permits and must be lifted up as the screw rotates against it. The lid: is preferably raised by the means set out in claim 2 or 3. The entire arrangement of the debris remover is preferably implemented by means according to claim 4. The latch is released from the cab, for example, by means of a rope, whereby the cover is pushed in and rises and locks up automatically.

In the following, the invention will be illustrated by means of examples with reference to the accompanying figures, which show an embodiment of the invention.

Figure 1 shows a granulation machine with a debris remover [j

Figure 2 shows the arrangement of the debris at the end of the feed pipe as seen from the side of the pipe. Figure 3 shows a cross-section from I1I-1I1 in Figure 2. Figure 4 shows the arrangement of the debris as seen from the end of the transfer screw

Figure 1 shows a pellet milling machine with a disc mill mounted on a debris remover. This is placed in the supply pipe 2 very close to the matrix plate 1. The most important part of the system is the inwardly opening lid 5, from which the waste mass is discharged if necessary. The latch member 8 keeps the cover S locked in the closed position. This can be released by means of the IS rope 9, whereby the spring 7 presses into the cover 5.

Figure 2 does not show sealing rubbers 12 and 14 which seal the long edges of the closed lid 5.

The lid 5 is triangular in such a way that the inclination of its oblique side is smaller than that of the screw 3. The lid 5 is hinged at its wider end? 0 hinged to the tube 2. The spring 7 tends to turn the lid 5 inwards. The spring 7 is mounted on the shaft extension of the cover 5.

Figure 3 shows the rubbers 12 and 14 sealing the edges of the lid 5. The lid 5 comprises an edge strip 13 pressing against the seal 14. Any small gap in one of the edges 25 of the lid 5 will not be a problem, as the fibers in the pulp quickly block it .

Figure 4 shows the lid in the open position. It can be seen from this figure that the cover 5 can be fully open more than half a turn of the screw 3. When the lid 5 is open, the screw 3 presses the mass flow and with it any blockage out of the opening formed by the lid 5. The tip of the screw 3 comprises a cutting blade sliding against the matrix plate 1, the vertical surface of which at the same time acts as a cam 4 for lifting the lid 5.
