    The invention relates to polymechanical engineering, in particular to equipment for the processing of powdered plastics. The closest in technical essence and the achieved result to the proposed is a two-stage extruder for thermoplastic Maccj of predominantly powdered plastics, containing two perpendicularly arranged extrusion stages with relative to each other axes with individual rotational drives, the first of which is equipped with a screw screw cut and positioned vertically, and in the lower part of the working area is connected by a connecting channel with the working area of the second, horizontally located zhennoy, steps, and a throttle device for changing the communication passage sectional C. The disadvantage of this extruder is that it does not allow to achieve high productivity and at a sufficient plasticizing homo genizatsii processed material as to avoid the plastic heating nedopus timogo limited number of screw turns. The purpose of the invention is to increase the performance of the extruder. The goal is achieved by the fact that in a two-stage extruder for thermoplastic masses, mainly powdered plastics, containing two perpendicularly arranged with axis displaced relative to each other, extrusion stages with individual rotational drives, the first of which is equipped with a screw screw with a thread and vertical. and in the lower part of the working area communicated with the connecting channel with the working area of the second, horizontally located, stage, and the throttle device for measuring The cross section of the connecting channel, the feeding screw is provided with kneading disk-shaped elements placed between the screw thread sections, displaced relative to each other in the circumferential direction, and cylindrical pins located between the kneading disk-shaped elements, and the upper end of the feeding screw is mounted in a bearing.
    In addition, cylindrical pins are mounted with the possibility of radial movement.
    Kneading disk-shaped elements placed in the zone of the connecting channel of the vertical stage are displaced 5 in the circumferential direction opposite to the direction of displacement of the kneading disk-shaped elements.
    FIG. 1 shows a schematic of a 10 two-stage extruder, general view; in fig. 2 shows section A-A in FIG. 3 shows a section BB in FIG.
    The two-stage extruder contains two perpendicularly located with 5 s; extrusion stages with each other blasted with mercury relative to each other, the first one of which is located vertically, and the second one - horizontally.
    The vertical stage 1 is placed jn on the case 3 in which the motor and gearbox (not shown) are located for transmitting the rotation to the delivery screw 4. The horizontal stage 2 is provided with a support 5 fixed on the base b, and is driven by a unified unit 7 drive.
    Vertical stage 1 (Fig. 2) contains a feed funnel 8, into which the press material is metered from the hopper 9 by means of a dispensing screw 10.
    The feed screw 4 is provided with spaced between the sections of the screw thread 11 displaced relative to each other in the circumferential direction by kneading 35 disk-shaped elements 12, which can be oval, elliptical or triangular in shape. Cylindrical pins 13 are placed between the kneading disk-shaped elements 12 and entering into the grooves 14, made on the feed screw 4 or opposite the round disks 15 placed between a pair of disk-shaped elements 12. Passing through the loading screw 45 on the top end of the feed screw 45 4 a funnel 8 is a supporting neck 16 mounted in a radial bearing 17 placed in the lid 18 of the loading funnel 8. At the lower end of the feed screw den 4, the reverse return thread 19 and the drive rod 20 are made. Work cylinder 21 is vertical the stool 1 is mounted on the block 22, in joTopOM there is the lower part of the 5-day auger 4, where the rotary bushing 23 with the protrusion 24 is mounted, on which the arm 25 is fixed to rotate the bushing 23, and the through hole 26 for the passage of material into
    60 horizontal step 2.
    In the horizontal stage 2, a driving screw 27 is placed, and in the region of the connection of the stages 1 and 2, a hole 28 is made for the discharge of gases, a joint 65
    whelped with atmosphere or vacuum pump. At the end of the horizontal stage, an extrusion head 29 is fixed. In block 22, opposite the connecting channel 30, a further discharge outlet 31 is made, which is blocked by a rotary sleeve 23. The operation of the two-stage extruder is carried out as follows. The recycled plastic is supplied to the feed hopper 8 in the form of powder, milling or pellets. The screw thread material 11 is fed into the working cylinder 21 where mixing and mixing takes place. The kneading disk-shaped elements 12 form alternately wedge-shaped tapered spaces with narrow gaps for shearing the material with the wall of the cylinder 21. - Cylindrical pins 13 tear apart particles and lumps of material and provide turbulence and mixing of plastics and fillers. At the end of the feed screw 4, a pressure is created which extrudes the extruder plasticized into the horizontal step 2. In the transition zone, kneading discs (different elements feed the material in the opposite direction. In horizontal stage 2, the mass is degassed and supplied with further homogenization and temperature control to extrusion head 29.
    The presence of kneading disc-shaped elements 12 provides free mixing spaces in which when interacting with cylindrical pins. 13, stronger mixing and supply of higher shear energy are possible even with partially filled screw channels. Recyclable plastics are continuously torn and mixed. Even hard dispersible, the pigments are evenly mixed with the plastic. Since in the presence of a vertical stage 1 of the extruder it is possible even to supply high shear energy to the plastic even with partially filled screw channels, the extruder can operate with a very large number of revolutions and, consequently, with high productivity.

    [1]
    Kneading disk-shaped elements are always displaced in the circumferential direction relative to each other, so that on both sides of each disk-shaped element the melt falls into adjacent channels, which ensures good displacement from channel to channel Depending on the location of the kneading disk-shaped elements and the direction of their rotation, positive or negative effe axial feed. The pre-compacted plastic is prevented from rotating together with the plasticizing agent with cylindrical pins, which ensures a substantial displacement and mixing of the material. The top support of the vertical feed screw provides a high number of revolutions, and the support neck 16 makes it possible to additionally install preliminary compaction organs in the feed funnel 8. The cylindrical pins 13 with radial displacement allow the gap between the ends of the cylindrical pins 13 and the surface of the circular disk to change between kneading disc-shaped elements Depending on the properties of plastic, cylindrical pins are installed with a larger or smaller gap. Kneading disk-shaped elements 12 placed in the zone of the connecting channel 30 are displaced in the circumferential direction: opposite to the displacement of the kneading disk-shaped elements in the working area of the feed screw 4, which facilitates the transfer of plastic to the horizontal stage 2 and prevents the mass from penetrating into the lower support. The presence of a rotatable sleeve provides for regulation of the pressure of the plastic and, thus, the processing time of the mass, shear intensity and temperature of the mass. The cross section of the connecting channel 30 is varied by rotating the sleeve 23, and the pressure in the vertical stage 1 of the extruder is adjusted. The through hole 26 of the rotatable sleeve 23 can be aligned with an additional outlet 31 communicated with free space, whereby the rotary sleeve 23 can be used as a trigger valve. Using the proposed extruder will allow you to recycle a layer of the mass in the form of powder or granules with high capacity. Claim 1.
