The purpose of the invention is the -SUKSUK .4 pr-process of processing matri-ns. account of the development of a working on erb .jcvn / device.
    This goal is achieved by the fact that in a device for processing solid and viscous polymeric materials containing a rotor with a rotational drive, a housing placed outside the rotor is coaxial to it and forming a working gap for the material with it, an inlet and outlet openings located in the housing parallel to the longitudinal the rotor axis, with the distance between the inlet and outlet openings around the circumference of the housing chosen greater in the direction of rotation of the rotor than in the direction opposite to its rotation, and at least one blocking A second element placed between the inlet and outlet openings and having a back wall and a cleaning section, the rotor is provided with discs mounted perpendicular to its longitudinal axis, forming between themselves and with the housing and rotor surfaces material channels communicated with the inlet and outlet openings .
    In addition, the device is equipped with jumpers placed in each working channel,
    The jumpers are mounted so as to move in the radial direction to regulate the flow area of the working channels.
    The locking element is mounted with the possibility of radial movement.
    The device is equipped with pipelines for communication of the exit section of one working channel with the entrance section of the other.
    The principle of the invention is to provide a processing surface in the form of an annular channel having two side walls and a bottom surface substantially perpendicular thereto, closed by an annular channel located opposite the bottom surface. The walls of the channel rotate continuously in one direction and the annular sealing of the surface associated with the channel is fixed. Thus, the material introduced into the channel will be subjected to the dynamic influence of the entire surface of the rotating channel, as well as the impact of the resistance exerted by the fixed surface. The delay of the material at the exit (separated from the entrance by the main part of the device’s perimeter) causes the material to be held in the channel for further processing of the material by the rotating surface of the channel and to develop an appropriate pressure during controlled discharge from the device. Corresponding coordination of the material supply, the speed of rotation of the channel walls and the speed of discharge
    The recycled material gives the device greater versatility when processing materials with various properties and processing requirements over a wide range.
    The concept of continuously rotating walls bounding the channels also contributes to the creation of relatively simple modifications of the device that meet the requirements of the materials being processed or the desired state of the final product. For example, in order to cause the material to spread
    5 of the channel surface and thereby facilitate the removal of substances (volatile gases, etc.) or the suppression of materials (pigments, fillers, etc.), the working channel in the region of the circular movement of the material provides braking resistance. In addition, devices are positioned in the area of the rotating cage to facilitate the mixing and / or melting of materials in the channel.
    5 In one fixed housing, a series of working channels with rotating walls can be formed, thus achieving the efficiency of using the working surface. If necessary, several or all channels are combined to transfer material processed in one channel to an adjacent channel for further processing. Each of these named channels or groups is used to implement multi-stage processing. For example, one or two channels (with movement of the processed material by connecting the output of one channel to the entrance of the next one) can be used to melt, another one or two channels — to remove volatile products, another one or two channels — to introduce pigment, filler or other 5 additives, one or two additional channels for further mixing and removal of volatile substances, and another channel for collecting and unloading recycled material.

    It should be emphasized that the area of the working channels together with the material being processed is located around the circumference (i.e., normally relative to the longitudinal axis) of the device: 5 from inlet to outlet, which makes the device very compact in size relative to its performance.
    . 1 shows a device in plan view; in fig. 2 is the same, with a partial section of it in FIG. 3 is a sweep of the working channel illustrating the movement
    material inside the channel; 4 shows an embodiment of ycrpoficTEia; FIG. 5 is a section A-A in FIG. four.
    A device for processing solid and polymer materials 1) Holds a rotor made in the form of a 1st. And an aquatic hall 1 (rotary drive shown) and fitted with installed perpendicular to its longitudinal axis rotatably on the shaft 1 of a disk UII 2 located at a distance of from each other inside the housing 3 |, coaxially in-alu 1 rotor and forming a working gap with it. The disks 2 have annular, preferably cylindrical, sections 4 of the outer surface and form with each other and with the surfaces of the housing 3 and the rotor shaft 1 at least one working channel 5 for the material, which communicates with the inlet 6 and the outlet 7 holes. The inlet 6 in the housing 3, parallel to the shaft 1, is intended to feed the polymer material from the hopper 8 into the working channel 5. As the boot device it can (i) either a simple hopper based on gravity or boot device of screw, plunger, disk type with heating, which is determined by the properties of recyclable material,
    The outlet 7 is located in the grommet 3 parallel to the longitudinal axis of the housing 3 and the shaft 1, the distance between the inlet b and the outlet of the 7 and 7 holes being large in the ng1 Rotation shaft 1 of the rotor, than in the opposite direction to its rotation. The rotor shaft 1 is kreg; and: tsrg in the end plate 9 of the housing 3 "In the area of the outlet 7 between it, at least one locking element 10 located in the housing 3 with a radial movement and having a wall 11 and a cleaning section is located in the inlet b. Each locking element 10 is placed in each working KaHaj-e 5 and has a shape that complements the shape of the working channel 5 and is appropriate for it, and the back wall 11 is exposed at any suitable angle depending on the material and the desired treatment, while the gap between the locking element 10 and side walls 12 of the disc 2 is minimal. At the output of the device set naschku 13.
    During the device operation, plastic or polymeric material in a solid or liquid state is supplied by means of a loading device; through the inlet 6 each working channel 5.: When the shaft 1 and discs 2 turn, the main mass of the material is held by the back wall 11 of the locking element 10 so that the side walls 12 of the discs are moved relative to the mass of the material and the material adjacent to the opposite side walls 12 bounding the working channels 5 is pulled by the side walls forward towards the rear s wall 11 of locking member 10 with a gradual increase in pressure which reaches a maximum at the location where the locking member 10 protrudes and which then falls.
    Material in the form of solid granules Sfig. 3) tightly laid on a solid base, which is a consequence of the relative movement between the rotating side walls 12 of the disk 2 and the working channel 5 and solid particles inside the channel 5. The walls 12 bounding the channel 5 can be preheated, but in any case the time of relative motion is released and heat is formed on the side walls 12 of the disks 2 and a film of molten plastic or polymer material is formed. The film is formed in such a way that the film moves with the walls 12 and shifts significantly when moving relative to the main mass of the plastic polymer material in the working channel 5 for further heat accumulation due to viscous dissipation. The involvement of the side walls 12, limiting the working channels 5, in drawing forward along its material surface forward gradually creates pressure along the length of the side walls, which reaches a maximum in the place where the locking element 10 acts, which cleans and collects viscous liquid material advanced side walls 12; this material is collected in the form of a settling tank at the rear wall 11 of the locking element 10 and can be removed from the working channel 5 due to the generated pressure.
    The continuous flow of material (Fig. 3), pulled forward by the side walls 12, provides rotational movement in the settling basin of the molten material, and this rotational movement creates a strong mixing effect. Likewise, an intensive mixing action can be achieved in the liquid feed material due to the correct choice of operating controls.
    When processing polymeric or plastic materials that have the same characteristics, such as the material usually manufactured
    in screw extruders, which are or are becoming in the process of making liquids with high viscosity, coordinating the physical structural qualities and operational controls in the device provides a technological process, the essence of which is the movement and extrusion of solid materials; melting or plasticizing solid materials; in moving, pressing or injecting liquid or melted material; mixing, stirring, decomposing and homogenizing the material; in semi-evaporation and a combination of these technological operations depending on the supply of hard and viscous material or a combination of both. This device is used to fill molds of various configurations (flat, shaped, cross-shaped, molds in which the cable is made and the surface layer is applied to the wire). Such a mold nozzle 13 (Figures 1 and 2) is installed directly in the outlet 7 of the device. The device is used to create microscopic and macroscopic structural changes in the material in order to modify, change or improve some properties of the material through a chemical reaction, such as polymerisation of prepolymers and monomers, leading to viscosity of polymer fluids, crosslinking, chain breaking, foaming and the like The design variables of the machine include the geometry of the annular working channel (s), the type of loading device, the size and location of the inlet , The shape of the locking element (s), size and location of the outlet.
    The geometry of the working channel 5 must. Provide a balance of various assignments for which the channel serves. Since the side walls 12, limiting the working channel 5, are the main elements of the technological process, a narrow, deep channel 5 is used, the depth of which is at least the same and preferably many times larger than the width of the channel. The cross section of the working channel 5 should be of appropriate shape, the distance between the opposite walls-sides 12 of the disks 2 should be sufficient for the material to pass to the base of the working channel 5 and directly fill it; but the balance factor is to force the working channel 5 to
    the creation of pressure was maintained close to optimal and working channel 5 was not so wide that pressure dropped in it. Melting, mixing and pumping or creating pressure increases as the size of the passage of the walls of the working channel 5 increases, passing the material, but the ratio of the area of the side walls of the channel to its volume should be such that when solid material is fed into the working channel 5 side walls (the material filled part of the working channel 5 for subsequent melting at the desired speed and
    5, the molten material uniformly filled part of the working channel 5 in order to achieve the necessary mixing and injection or to create pressure in the material to
    0 subsequent release. The linear velocity of the portion of the side walls 12 at a given rotational speed increases in proportion to the radial distance of each portion of the side wall from the axis of rotation; it was found that the change in the technological process depending on the change in the radial distance from the axis can be compensated for by increasing the gap H between the channel walls in proportion to the distance R from the axis, therefore the ratio H / R is constant.
    Work channels 5 formed
    5 with the opposite walls 12 of the discs 2 mounted on the shaft 1 at a distance from each other with the possibility of its adjustment (Fig. 1), ensure the processing of various
    0 polymeric materials, which allows the use of the proposed device for the experimental analysis of the manufacturing process of various viscous and solid materials.
    The distance between the side walls of the discs 12 of the discs 2 is easily changed by using different shims; the depth of the channels can be changed by using end shims of different diameters; the number of working channels 5 due to the removal and addition of disks 2 in order to ensure the operation of the device during the processing of various materials. Using
    5, the design of the working channels 5, formed by disks 2 with a rectangular cross section, shows that they can be used to work on complex devices. In addition, the 2 Moryf discs have any shape and cross-section (not necessarily flat). The wedge-shaped or ribbed shape of the disks 2 is sometimes useful. Work channels can also be a ring.
    Trench grooves or passages formed in the rotating rotor.
    The loading device for supplying plastic, polymer or alological material to the south of the working Nanole 5 is designed to work with a specific material and the defined state of the material to be recycled. Where plastic or polymeric material to be recycled is supplied in the form of granules, the loading device will be designed to ensure that the working Channels 5 are filled from bottom to top, in order to efficiently use all the surfaces of the working channel 5 involved in the processing. A simple hopper passing through the inlet 6 is necessary in the case of using some granular materials, for other materials a mechanical loading device can be used, such as a screw or plunger type. In the case where the COMPLETE material is a viscous fluid, the charging device is a pipeline through which fluid flows into the working channel 5, or a pump, for example, of a screw or gear type, a device for feeding material at a desired speed and pressure,
    An outlet 7, passing through the housing 3, is located at least at the most part of the rotor's full rotation, while the counting is from the inlet 6 a. The speed control at which the recycled material has the ability to exit the working channel 5 is an important factor in determine the processing time of the material, and the outlet 7 is designed and located in a tachim manner to regulate the release of material. The adjustment can be carried out by selecting the size of the outlet 7 or by installing a butterfly valve or other means in the outlet 1, the rate of release can also be adjusted by connecting the outlet 7 with an additional tool, such as a nozzle 13 or MyHflijjTyK for extrusion , or something similar, which can provide the desired flow resistance that controls the rate of material release from the outlet 7 and the duration of the process sa, In one of the proposed modifications in the technological device, which has more than one working channel 5, release from one
    the working channel 5 is carried out through a pipeline going out to. the inlet of the next working channel 5 for the purpose of the most recent j. processing. Such an arrangement is particularly advantageous since the cycle during which pressure is created and injection into successive process working channels is cumulative, therefore high pressure is usually maintained at the outlet. For better processing of incoming matter, each of these successive working channels is different from each other. In addition, the tangible material processed in the first working channel 5 and produced from one or a given number of parallel operating channels 5 is fed to one working channel 5 or to any selected number of working kdals 5 operating in parallel. According to this embodiment (Figs. 4 and 5), certain loading devices and inlets are used to load each working channel 5 or any combination of working channels 5 with a plastic or polymeric material that is similar or different from the material loaded into any other channel or combination of channels. Different materials made in insulated working channels 5 or a combination of working channels 5 can be discharged through isolated outlets, fed to insulated pressing nozzles or to a nozzle for parallel pressing, for example, one material used as a rod, and another material - as a coating.
    According to the invention, the processing efficiency of plastic and polymeric material is achieved by installing the correct ratio of loading speed and material release into technological working channels, controlling the temperature and speed of moving the channel walls depending on the material properties and the geometry of the working channel 5.
    Using the proposed device, it is possible to recycle all plastic and polymeric materials, in a normal state, liquid or brought to this state by heating or mechanical energy or liquefied to a viscous liquid or deformed and possessing sufficient stability to avoid significant degradation under conditions recycling. Such materials include (but are not necessarily limited to) thermoplastic, thermosetting and elastomeric polymeric materials, for example polyolefins (polyethylene, polypropylene), vinyl chloride polymers (for example, polyvinyl chloride), polymer-containing fluories, styrene based on polymers (for example, polystyrene), polyamides (for example, nylon), acetals, polycarbonates, cellulose, plastic-based, polyesters, polyurethanes, phenols and aminoplastics, resin-based epoxides, silicone and inorganic polymers, polysulfone on the basis of polymers, various natural-based polymers and others, together with copolymers and mixtures of these materials with each other or with solutions or thinners; or with various solid or liquid binder products. In addition, it is assumed that. Reactive materials, such as blends, from which polymers can be obtained, and which are viscous liquids at some stage of their formation, are loaded into the device for processing in the working channels, provided that the temperature is maintained. The temperature of the material during the feed and during the process is controlled, so that the viscosity of the material being processed and its flow characteristics can be set. The feed and feed rates of the liquid viscous plastic or polymer material, the shape of the working channels, the speed of movement of the walls of the discs, the limiting channels, depend on each other depending on the properties of the selected material and temperature. On the basis of calculations, it was found that a disk radius of 16 cm is optimal with a channel width of 6 mm. Thus, the annular spacer N. N. OGO cross section of the working channel with an outer diameter of 32 cm, an inner diameter of 16 cm and a width of 6 mm at a speed of 30 rpm delivers 454 kg / h, melts and produces a pressure of 1500 psi ( 105 kg / cm). It has been established that a narrow and deep annular working channel creates difficulties for the effective supply of the material to be processed to the bottom of the working channel. In practice, this problem can be solved either by creating the necessary bevels for the housing (Fig. 5, in housing 3), or by using a plurality of working channels, the first of which is somewhat wider than the optimum value. If the feed material is in a solid state, then the first channel is preferably the narrowest, but still wide enough to be loaded under gravity. For conventional polymeric materials of particular shape, the channel must necessarily have a size of 6.3-63 mm. According to the constructive embodiment of the invention (Figs. 4 and 5), the working channels 5 are combined in series, in the case 3 a rotor is installed in the form of a shaft 1, which is mounted in the "end-plate 9 of the case 3. Ring working channels 5 are limited by the side walls 12 of the disks 2 which form a cross-section of the working channel 5 in the form of a wedge, and also have relatively wide sections 4 of the cylindrical surface on each side of the working channels 5. These cylindrical sections 4 of the surface closely slide from the coaxial cylindrical inner surface of the building usa 3, so that the inner surface of the housing 3 and the channels 5 form a closed annular passage. The chambers 14-16 are made inside the discs 2 for introducing a temperature-controlled fluid in order to transfer temperature through the walls of the working channel 5. The heat transfer fluid is supplied to the chambers 14-16 through the axial channel 17 provided in the shaft 1 through which temperature-controlled fluid is poured into the first chamber 14 through pipes 18, from the first chamber 14 through channel 19 to the second chamber 15, then through channel 20 to the third chamber 16 and through the next passage 21 to the tube 22 in the shaft 1. The inner surface of the housing 3 (Fig. 5) for the most part the length has a cylindrical shape, but a bevel 23 is made there, adjacent to the inlet 6 for feeding material into the working channel 5. This bevel 23 has such a width that it forms an intermediate chamber 24 with the cylindrical section 4 of the rsgore, so that when viscous the liquid material through the inlet port 6 it is drawn by the cylindrical section 4 of the rotor surface towards the zone where the surfaces of the walls of the frame 23 approach the cylindrical section 4 of the rotor surface. This process percolates the viscous material into the working channel 5. The locking element 10 mounted on the housing 3 has the form of supplementing the working channel 5 and is close to it, which holds the bulk of the plastic or polymer material and ensures its movement relative to the walls 12 and contributes cleaning up
