    A screw extrusion press having a barrel temperature control means is disclosed, which press permits the inner liner or cylinder of the barrel or a portion thereof to be replaced rapidly without necessitating simultaneous replacement of the temperature control means. This object is achieved by providing intermediate rings between individual extruder barrel portions, the rings each defining annular passages and guide means for the temperature control medium.

    The invention relates to chemical engineering, in particular to screw extruders, containing a device for tempering their cylinder, firewood for processing thermoplastic plastics and rubber.
    The purpose of the invention is to facilitate the replacement of a device for cylinder tempering.
    Fig. 1 shows the cylinder sections of an extruder with separate cylindrical holes peripherally located in the axial direction, a longitudinal section; 2 shows intermediate rings with annular canals ra arranged along their end surfaces, along the bottom section; on fig.Z - vkla; rings, longitudinal cut; FIG. 4 is a view A of FIG. 3; on fig.Z - type B on fig.Z; Fig. 6 is a diagram of the compasses of the tempering cooling medium in the intermediate rings and cylinder sections of the extruder with a sweep of supplementary rings.
    The screw extruder comprises a cylinder tempering device for processing thermoplastic plastics and rubber, made in the form of sections 1 of an extruder cylinder to reach a screw (not shown) with axially spaced individual cylindrical holes 2 communicated with means for supplying and discharging temperarun cooling medium ( not shown). The screw extruder is provided with extruder located between sections 1 of the cylinder with peripheral separate cylindrical holes 2 intermediate to rings 3 with annular channels 4 and 5 arranged on their end surfaces, respectively, and annular channels 6 arranged in annular channels 4 and 5 of the intermediate rings 6 for meander-like circulation of the tempering cooling medium. Along the end surface of the inset rings b, the milled recess 7 is made in the form of a longitudinal opening dp of covering alternately at least two peripheral cylindrical holes 2 of section 1 of the cylinder dp enabling the removal of temperate cooling medium and slotting holes 8 to enable the temperate cooling environment.

    left channels 4 in the intermediate ring
    3 are stepped with the formation of an inner annular channel of a smaller diameter and an outer annular channel of a larger diameter. To this end, steps 9 and 10 are made on both end surfaces of each intermediate ring 5, respectively. The sections 1 of the extruder barrel are provided with flanges 11 with bolts 12 arranged therein for connecting them to each other. Ring channels 5 and
    4 are equipped with an underwater 13 and 14 outlet holes, respectively. Each section 1 of the extruder barrel is made in the form of an outer 15 and an inner 16 shell.
    Screw extruder works as follows.
    Through the underwater hole 13, the tempering cooling medium enters the annular channel 5 through the through hole: hole 8 and is circled by a milled recess 7 (it is designed as a longitudinal hole to alternately cover at least two peripheral cylindrical holes 2 of section 1 of the extruder cylinder). At the other end of the peripheral separate cylindrical bore 2, this process is repeated, since the supporting ring 6 at this end is rotated one step of the milled recess 7. Then the tempering cooling medium enters the annular channel 4 and is directed to the bypass hole 14. The manufacturing process of the intermediate rings 3 is simple, since on both end surfaces only annular grooves are necessary for annular channels 4 and 5, respectively.
    The tabs 9 and 10 allow the insertion rings 6 to be precisely inserted and secured. Moreover, the insertion ring 6 and the intermediate ring 3 lie flush against each other and are pressed against the section 1 of the extruder cylinder by tightening the bolts 12 placed in the flanges 11, intermediate rings 3 are made with elements of centering and fitting (not shown) to create the possibility of preferable mounting of intermediate rings 3 ". If it is necessary to replace the inner shell t6 of section 1 of the extruder cylinder on both sides of section 1 from
