    A machine for the compression of a bulky mass (2), e.g. plastic-coated, shredded waste paper, so as to form a compact, elongated, well-integrated body, e.g. a fuel body for heating purposes. The machine has a driven screw arrangement arranged centrally in a conically tapering space (10) which comprises on the one hand a rear feed screw (13), partly located in the said space, and on the hand a front compression screw (18), arranged concentrically in relation to the feed screw, both the said screws being rotatable at mutually unequal speeds.

    专利说明:

    The invention relates to the pressing of materials of combustible industrial waste using screws or screws, in particular, to equipment for compacting the bulk mass into an elongated dense body.
    The purpose of the invention is the expansion of technological capabilities by recycling paper waste with plastic coating.
    The drawing shows a machine for compacting the bulk density, section 0
    Combustible dry waste in the form of bulk material 2 (paper with plastic coating) is placed in the cavity of machine 1 for compacting mass. The machine 1 for compacting bulk mass contains section 3 of the load, active working section 4 and uchastok 5 unloading placed on the frame 60 Section 3 loading is made in the form of an open top bunker 7 with side walls 8 and bottom 90 The hopper 7 is designed to receive paper intended for compacting waste 2
    Active working area 4 is made in the form of a body 10 in the shape of a truncated cone. The housing 10 is made with a conical extrusion chamber 11, which by its large base is connected with a hole made in the wall 8 of the hopper 7 adjacent to the active working section 4. The machine 1 contains a driving screw device in the form of successively placed hollow shaft 12 transporting auger 13 installed in the lower part of the bunker 7, and the drive

    shaft 14 of the pressing screw 15, coaxially installed inside the hollow shaft 12 with the possibility of free rotation 0 The transport screw 13 in the zone facing the pressing screw 15 is made with a step decreasing in the direction of the latter, and in the opposite zone with a constant step 0
    The pressing screw 15 is completely placed in the conical pressing chamber 11 of the Transporting screw 13 partially in a section with decreasing pitch placed in the conical pressing chamber 11
    The drive shafts 12 and 14 are driven in rotation by known methods using appropriate gearboxes from one engine, however, the rotational speeds of the shafts can be freely adjusted one relative to the other. In the best case, the shaft 14 of the pressing auger 15 should have a speed twice that shaft 12.
    A conical extrusion chamber 11 is made stepwise with a step 16 with a smaller taper angle facing the cylindrical outlet channel 17 formed in the housing 18 in the discharge section 5. This conical extrusion chamber 11 facilitates the flow of bulk material 2 into it.
    In the optimal case, the walls of the conical compression chamber 11 are made with longitudinal grooves or ribs, facilitating the movement of waste shumis Such grooves or
    the ribs 19 must be located on the wall 20 of the housing 10 "
    The bulk mass compaction machine works as follows
    Shafts 12 and 14 are driven in rotation from an electric motor (55 kW, 1470 rpm) through the respective gear boxes. In this case, the pressing screw 15 rotates at a speed of 882 rpm, approximately twice the speed of the transporting screw 13 (equal to 311 rev (mi) Bulk waste 2 paper comes from above and is collected in a bin 70 Waste is cut or otherwise homogenized waste paper with a plastic coating. Waste is captured by coils of the transporting screw 13 into its coiled space and space. Moving through the stepped hole 16 in the conical pressing chamber 11. Due to the fact that the waste passes through the gradually tapering hole in the conical pressing chamber, the waste mass undergoes pre-compaction during passing through the step 16 of the conical pressing chamber o During pre-compaction from the waste mass air is displaced. The pre-compaction is compensated for by gradually reducing the shaft diameter and the pitch of the screw turns in the zone of the stage 16 in the transport direction 13 "auger
    Pre-compacted in the zone of the step 16, the waste is conveyed by the conveyor screw 13 into the conical space of the pressing chamber I1 and moved there by the pressing screw 150 The waste is pushed into the cylindrical outlet channel 17 of the housing 18 of the discharge section 5
    Since the amount of paper passed through the zone of the stage 16 by the conveyor screw 13 is greater than the amount that must pass through the conical pressing chamber 11, which gradually tapers towards the cylindrical outlet channel 17, some accumulation of waste may take place in the feeding zone. However, this accumulation is eliminated due to the fact that i the pressing screw 15 rotates at a higher speed, and the amount of waste supplied per unit time by the transporting screw 13 exactly corresponds to exists amount of waste to be placed in the space between the turns of the compression screw 15 and the inner wall surface of the housing 10t During pushing the material into a conical compaction chamber due to frictional forces is allocated a
    the amount of heat that is sufficient to melt the plastic coating of the paper, resulting in fusion of the individual pieces of paper into an elongated, dense, shape-keeping body, continuously passing through the discharge channel 17 of the housing 18.
    The proposed machine ensures the sealing of combustible waste, in particular, plastic-coated paper waste without prior treatment of waste.
