A machine that compresses a bulky mass

The invention relates to a machine for compressing a space-consuming mass to form an elongate, tightly compressed Kap-5 piece, the machine having a conically tapering space towards the outlet opening and a used screw device located in the middle of the space, comprising a rear feed screw with screw threads and a front a compression screw having screw threads, wherein the screws are rotatable with each other at different rotational speeds.

Thousands of tonnes of combustible industrial waste are produced each year, the only economic value of which is that as much of its latent energy content can be recovered by incineration, e.g. for heating purposes. However, in order for such energy recovery to be possible at all, it is often necessary to treat the waste in some way, which in principle means that after sorting the inferior substance, the remaining, more combustible substance is converted to the final form suitable for incineration 20, e.g. polttopriketeiksi. This deformation or compression usually takes place on a machine of the type described, thus having a rotating screw in the middle of the conically tapered machine space, which compresses the waste helically through the space, gradually compressing it into an elongate, well-integrated and slot-stable combustion piece which is then cut prikettimuo-toon.

The known machine described here works well with waste · 30 which is more or less easily slippery in nature, but in contrast rarely or never with waste-paper type, dry and bulky waste pulps, in particular plastic-coated waste paper. arising from the manufacture of packaging laminates; 35 and the so-called liquid filler. for disposable packaging.

The only possibility with which a known screw-type machine can convert such dry paper waste into efficient, form-stable combustion briquettes has therefore been either to add more easily moving waste material to the paper 5 and / or to add water to moisten the paper and thus soften and make it more machine-friendly and easier to handle. However, such necessary measures have meant poorer thermal savings because the additional, added blending agent is generally less efficient fuel than "clean" waste paper, whereas deformation with water has usually required subsequent, energy-consuming heat treatment to dry the formed, moist burner.

It is therefore an object of the invention to provide a machine of the type described, which, however, unlike the known machine, enables efficient compression of combustible, bulky waste, in particular plastic-coated waste paper, without the necessary pre-treatments which impair the economy.

This object is achieved according to the invention by giving the machine described at the outset the characteristic features stated in the claims.

The invention will be explained and described in more detail below with reference to the accompanying drawing, which shows a schematic diagram. . A very simple but practical and well-functioning embodiment of the machine of the invention for producing form-stable burners from combustible, space-consuming waste material, in particular plastic-coated waste paper.

Thus, the drawing shows a machine according to the invention, indicated by general reference 1, for compressing a space-consuming mass of combustible, dry waste material 2, the waste material in the example described here being plastic-coated waste paper. The machine 1 comprises essentially three machine parts, namely 35 an input part 3, an active working part 4 and 3 86045 an outlet part 5, which parts are built together as a machine unit which can rest on a base 6. The inlet feed section 3 of the machine 1 comprises a horizontal bottom wall 7 and a substantially open-walled box 9 delimited by a substantially vertical side wall 8 for receiving and collecting the top-fed waste paper 2. The box 9 is connected via a hole in the front (left) side wall 8 to a conically tapered compression space 10 in a housing piece 11 placed against this side wall 10 of the active machine part 4. The rear (right) side wall 8 of the box 9 is provided with a corresponding a hole for a rotatably mounted, hollow drive shaft s 12 for a feed screw 13 placed down in a box, having a rear screw part 13a 15 completely in the box 9, the screw threads 14 having the same thread height, and an anterior screw part 13 extending at least partially conically tapering to the space 10 , the thread heights of the screw threads 16 of which are gradually smaller towards the space 10. In the center of the cavity of the drive shaft 12, a freely rotating drive shaft 17 is mounted straight in front of the feed screw 13 for a compression screw 18 completely located inside said space 10. with smaller directional. sa towards the outlet 20 of the space 10. The drive shafts 12 and. 25 17 can be driven in a manner known per se by means of a suitable gear and with the same motor (not shown), and according to the invention it is important in this case that the transmission between the motor and the shafts 12 and 17 is: arranged so that they can be operated in proportion to: 30 with freely adjustable speeds. In this case, the shaft 17 of the compression screw 18 is preferably designed to be operated at twice the speed of the shaft 12 of the feed screw 13.

In order to make it easier to feed the space-consuming waste paper 2 into the compression space 10, in this space the feed area 21 is turned towards the plate 4, the conical shape of which is slightly larger than the anterior zone of the space 10, which tapers conically towards a sharper apex angle. . In addition, the space 10 preferably has surface irregularities that facilitate the feed-forward 5 of the waste paper 2, e.g. longitudinal parallel grooves or ridges 23 evenly distributed around the inner wall 22 delimiting the space of the housing body 11.

Finally, in the outlet part 5 of the machine 1, a hollow, substantially cylindrical housing body 24 is placed against the housing 11, which is located so that the axial, cylindrical cavity 26 of the housing body 24 is a direct extension to the outlet opening 20 of the conical space 10.

The machine 1 according to the invention described above operates 15 as follows. By means of said motor (which may be a known 55 kW electric motor with a speed of 1470 rpm) the shafts 12 and 17 are driven via a suitable transmission (e.g. a known gear) so that the clamping screw 18 is rotated at a speed (e.g. 882 20 k / min). min), which is about twice or even higher than the corresponding speed of the feed screw 13 (e.g. 411 rpm). The bulky paper waste 2 fed from above and assembled in the box 9, which in this example is finely chopped or similarly homogenized, plastic-coated waste paper, is then caught and fed helically forward in the space between the screw threads 14 of the screw 13 and inside its conical space 10 through the open, wider end of zone 21. Since the free space between the feed screw 13 and the inner wall of the housing body 11. In this, it gradually decreases inwards towards the space 10, due to the conical narrowing of the feed zone 21, a certain pre-compression is applied to the pulp-like pulp thus fed as it passes through the feed zone 21. However, this pre-compression, which essentially means the extrusion of the accompanying air, becomes somewhat compensated, as both the shaft and the height of the screw threads 16 in the front screw part 13b inside the inlet zone 21 taper and correspondingly decrease in the feed screw 13 5. in the feed direction.

Thus, the paper waste fed forward by the feed screw 13 through the feed zone 21 'and pre-compressed is further fed through the space 10 by means of a press screw 18 in front of the feed screw 13 and completely inside the conical space 10 and inside the housing 24 into the cylindrical outlet cavity 20.

Since the amount of paper fed by the feed screw 13 through the feed zone 21 is greater than the amount 15 to which the gradually tapering space 10 could actually receive and feed forward, this means that a certain accumulation of fed paper waste inevitably occurs in the feed zone 21. The invention however, this phenomenon 20 is avoided by rotating the compression screw 18 at a higher speed than the feed screw 13, more specifically at such a speed that the amount of feed screw 13 supplied per unit of time corresponds exactly to the number of times per unit of time the compression screw 18 is capable of ; 19 and the inner surface of the housing body 11.

However, this free space gradually decreases towards the outlet opening 20, and during the feeding by the pressing screw 18, heat is generated in the paper waste thus fed due to the internal friction. The heat of friction generated is high enough for the plastic coating of the pieces of paper (e.g., polyethylene) to melt, causing the surface of adjacent pieces of paper to fuse to form an elongate, compressed, and thus melt-shaped fuse at the surface. • is continuously extended through the cavity 26 of the housing body 24.
