    Eine Einschneckenstrangpresse für thermoplastische und elastomere Massen weist ein hohlzylindrisches Gehäuse auf, das mit radial nach innen ragenden Mischelementen versehen ist Diese Mischelemente treten durch Aussparungen des oder der Stege einer in dem Gehäuse gelagerten Schnecke hindurch. Um die Schneckenstrangpresse einfach montieren und leicht reparieren zu können, ohne das gesamte Gehäuse austauschen zu müssen, sind die Mischelemente (10) an geteilten Ringen (9) vorgesehen, die durch zwischen diesen angeordnete Distanzringe (17) im axialen Abstand voneinander gehalten oder die in Nuten von das Gehäuse bildenden ringförmigen Gehäuseabschnitten (5', 5") festgeklemmt sind (Figur 1).

    The invention relates to chemical engineering, in particular to single-screw extruders. for thermoplastic and elastomeric masses.
    The purpose of the invention is to facilitate disassembly and assembly during repair.
    FIG. 1 shows a single-screw extruder for thermoplastic and elastomeric masses, longitudinal section; in fig. 2 is a section A-A in FIG. 1J in FIG. 3 — the screw extruder in FIG. 1 at the location of the support rings in the embodiment in them
    the channels alternately tilted with Bnpo opposite directions, in FIG. 4 a section BB in FIG. 3
    The single-screw extruder for thermoplastic and elastomeric masses comprises a hollow cylindrical body with a feeding zone 1 with a total length F and a mixing zone 2 with a total length M and radially fixed along its inner surface in the mixing zone 2.
    protruding inside the mixing elements 3. In a hollow cylindrical body coaxially mounted there is a screw to 4 in the form of a core with screw thread 5. The heating and / or cooling elements 6, as well as the supports 7 of the hollow cylindrical body are shown schematically. Separate parts of the hollow cylindrical body are connected by bolts 8. In the turn or turns of the screw thread 5 there are recesses 9 for mixing elements 3. The latter can be made in the form of pins. In this case, the notches 9 can be made with a smaller axial length. The extruder is provided with coaxial and alternately positioned in the cavity of the cylindrical body in the mixing zone 2 support rings 10 and spacers 11 to hold the support rings 10 axially apart from each other, provided with retainers 12 to prevent them from rotating relative to the hollow cylindrical body. The mixing elements 3 are fixed on the support rings 10. The locking pins 12 can be made in the form of prismatic keys to prevent rotation.
    In an embodiment of the extruder, the hollow cylindrical body is made as separate tubular sections interconnected with lengths of 7 ", F". performed at the ends of the flange c 13, and on the internal face

    The surfaces 14 of the flanges 13 of two adjacent tubular sections are respectively provided with annular grooves 15 and annular protrusions 16 for placing support rings 10 with mixing elements 3 between them. In an embodiment, the supporting rings 10 are made split in their middle plane and in the cut area on their outer the sides are made symmetrically with respect to the axial mid-plane of the grooves 17 to accommodate the clamps 12 to prevent rotation, which are installed in the dp of their placement along the inner surface of the hollow bore hull 18. In the embodiment, in the support rings 10, channels 19 are made, alternately inclined in opposite directions. Their entrances and exits are located respectively in the zone of the wall of the hollow cylindrical body or the core of the screw 4. The notches 9 for the mixing elements 3 can be made circular and grooved with a larger width L, which increases the useful passage surface of the support rings 10. The supporting rings 10 enters deeper into the lateral surface of the hollow cylindrical body, with the inner wall of the hollow cylindrical body as well as the core 4 of the screw being made with transitional conical surfaces 20 to improve odvoda melt thermoplastic and elastomeric mass in the channels 19.
    A single-screw extruder operates as follows.
    The melt of thermoplastic and elastomeric masses is fed with a screw 4 from zone 1-feed to zone 2 of mixing. Due to the fact that the hollow cylindrical body is provided with heating and / or cooling elements 6, a uniform temperature is maintained in the mixing zone 2. In zone 2, the melt is thermoplastic and elastomer-. The masses are exposed to the mixing elements 3, crossing the notches 9 of the screw 4, resulting in good mixing, since the mixing elements 3 prevent the melt from rotating with the screw 4. Because the mixing elements 3 are fixed on the support rings 10, case of individual damage.
