    • 专利摘要:
    A pin-barrel extruder (1, 2, 4) used for processing rubber or thermoplastics materials or for the removing of water from liquid/solid mixtures has pin adjusting means (6). The adjustment means (6) comprises a plurality of hydraulic piston and cylinder arrangements, the cylinders being mounted on the external surface of the barrel (1) and each pin (4) forms a part of the piston rod of each arrangement. Each pin (4) may be integrally formed with, or detachably affixable to the piston rod with which it is associated. By so doing, the pins (4) are insertable into and retractable from the interior of the barrel (1) in a simple manner. If desired, check valves may be provided so as to make it possible to displace the piston rods individually, in groups or all simultaneously, thereby permitting the pins (4) to be moved into or out of the extrusion barrel (1) interior extremely quickly. <IMAGE>

    The invention relates to chemical engineering, in particular, to devices for adjusting the cores of a rod extruder.
    The purpose of the invention is to facilitate the installation and dismantling of the device.
    FIG. 1 shows a part of the hollow cylinder CQ with a screw and rods, a longitudinal section; in fig. 2 is a section A-A in FIG. one.
    A device for controlling rods of a rod extruder contains a Poland cylinder 1 coaxially mounted therein rotatably (drive not shown) screw 2 with a spiral blade 3 along its outer surface, rods distributed in the radial direction along the inner surface of a hollow 1 cylinder 1: at the same distance from each other along the circumference and directed to the longitudinal axis of the screw 2, the mechanism for adjusting the depth of immersion of the rods.
    Through the outer surface of the hollow cylinder 1 there are made through radially directed holes 4. In the spiral blade of the 3 screw 2 opposite to the through radially directed i holes 4 there are made cuts 5 for placing and moving the rods. The depth adjustment mechanism; immersion of the rods is made in the form of hydraulic cartridges fixed on the outer surface of the hollow cylinder 1 of the extruder, containing hydraulic cylinders 6 which are attached radially to the hollow cylinder 1 of the extruder, and the rods are made in the form of rods 7 of hydraulic cartridges. In order to determine the depth of the rods, the rods 7 of the hydraulic cartridges are designed as axially mounted in hydraulic cylinders 6 by means of hydraulic cartridges of rods 8, provided with markings on their ends opposite to the ends placed in the cavity of the extruder cylinder 1.
    A device for adjusting the rods of the rod extruder operates as follows.
    The processed material (rubber or thermoplastic plastics) enters the cavity of the extruder cylinder 1. The screw 2 rotates and moves the material using a spiral blade 3. Besides the fact that the material

    rotates with the screw 2 and moves with the spiral blade 3, it is subjected to additional impact of the rods at the points of the gaps 5 in the spiral blade 3, which contributes to obtaining a higher-quality material. The rods are made in the form of rod 7 hydropatron, and this allows you to change the level of their installation in the cavity of cylinder 1: simply push it in or push it, and this can be done both along the entire length of the hollow cylinder 1 and around its circumference. Since all hydraulic cartridges mounted on the outer surface of the hollow cylinder 1 of the extruder can move the rods either simultaneously, or all the rods in the same radial plane, or all the rods of one section of the hollow cylinder 1, it is possible to make an individual setting in accordance with the specific temperature or viscosity of the material being processed extruder area limits. If it is necessary to remove the screw 2, for example, for cleaning, then in this case the rods can be removed from the hollow body 1 of the extruder for a few seconds, and then bend the screw 2. The rods can be screwed into the rods 7 of the hydraulic chambers (or vice versa), In this case, you can easily and quickly replace them in case of wear. The presence of the marking allows visual control of the depth of the rods.
