    The invention relates to devices for preparing electrode material from pitch and powdered coke of various grain sizes, by mixing and then molding the mixture into coal formation and can be used to make an electrode paste for producing electrodes used in the electrochemical process for producing aluminum in the aluminum industry.
    The aim of the invention is to increase the capacity of the device for the continuous preparation of the electrode material.
    Figure 1 shows the scheme of the proposed installation; figure 2 - unloading device, side view; on FIG. 3 - the same, horizontal gas cut.
    The device has a continuous-running mixer 1, which performs a kneading action, and contains a screw shaft 2 mounted in the chamber 3 of the mixer 1 for rotation and at the same time reciprocating motion. The screw shaft 2 is equipped with a mixing device and kneading blades 4 interacting with the kneading bodies 5 extending inwards from the inner wall of the chamber.
    Mixer 1 intensively mixes powdered coke of various sizes with each other, mixing with one another, pitch. The granulometric fractions are stored in separate bins and are fed in metered quantity into chamber 3 through the charging opening 6. The pitch is added in solid or liquid form through the same opening or through injection nozzles embedded in the kneading chamber.
    On the discharge side, the mixer 1 is connected by a vertical shaft 7, its lower end, to the chamber 8 of the extruder 9. A discharge valve 10 is provided in the connecting shaft, blocking in normal position the connection of the discharge hole 11 with the internal volume of the shaft 7 and forming part of the inner wall of the shaft 7 ; in the position shown on the diagram by the dashed lines of the discharge valve 10, the discharge opening 11 is released and the lower part of the connection

    sleeping ottoman 7 is locked. To relocate the discharge valve 10, there is an actuating motor 12 which can be controlled via the control member 13.
    At the upper end of the connecting shaft 7 there is a nozzle 14, to which the steam extractor 16 is connected via the suction pipe 15.
    Automatic shifting to the unloading position of the valve 10 in the shaft 7 is carried out with the help of an actuating motor 12 when the predetermined nominal torque is exceeded on the shaft of the mixer 1 and also in conjunction with the results of monitoring the operation of the extruder 9 driven by the motor 17.
    The extruder 9 (Figures 2 and 3) has a chassis 18 equipped with channels 19 and having the ability to move on rails. On the chassis 18, an extruder chamber 8 is placed, which is made of two parts in a horizontal plane and can be opened. The upper part of the chamber 8 is provided with a loading nozzle 20 and one end side of the chamber bears on itself an exit nozzle 21, which can be made adjustable. The electric motor 17 is placed in the chassis 18 and through the V-belt drive 22 or by means of a coupling is directly connected to the extruder gearbox placed in the chamber 23 located at the end of the chamber 8 remote from the discharge nozzle 21 21. The chamber 8 has a removable end wall at one end 24, the carrier part of the chamber 23, in which the gearbox is placed. Part of the chamber 23 is provided with the following end wall 25.
    In the chamber 8 of the extruder 9, four extruder shafts 26 are placed, arranged side by side in the horizontal mid-plane of the chamber 8 and having a one-sided support in the end walls 24 and 25. The respective bearings are labeled 27 and 28. Hollow shafts 29 are connected to the shafts 26 , equipped with worm coils 30, which are in engagement with each other, that
    creates augers rotation in the same and opposite direction. Hollow shafts 29 with plug-in connection
    connected to the related shaft end pivot, and slotted pins and axles are provided for fixing. The output of the mixed material along the shafts is prevented by the labyrinth seals 31. In the part of the chamber 23 there are gears 32 on the end pins of the shafts 26, which together form the drive gear and are connected with the electric motors 17.
    The other end of the chamber 8, which is remote from the end wall 24, is open and carries the output nozzle 21, with the hollow shafts 29 with the screw turns 30 extending to the inner opening of the output nozzle 21. The elements of the former 33, made of two parts of the nozzle 21, cast on the upper or lower part of the nozzle and made in the form of cross-beams screwed to the upper and lower parts of the nozzle. In the nozzle 21, continuous bars are formed, for example up to 50 bars, but nozzles are preferably used that have shaping channels for four to thirty bars. Some of the shaping channels 34, which can be inserted with a quadrilateral, round or oval cross-section, are designed to lock them, for which gates or locking rods are used. The dampers can be controlled mechanically, pneumatically, hydraulically or electrically.
    The upper part of the nozzle 21 is designed to open out, and the upper part can be moved with the help of pivoting levers. The expansion can be done manually or automatically,
    for example, by means of a valve control, indicating the occurrence of an overpressure inside the nozzle 21 and giving an alarm signal.
    The number of revolutions of the extruder shaft is controlled depending on the level of the material in the connecting shaft 7. For this purpose, a level measuring device 35 is provided in the shaft 7, continuously measuring the level of the material supplied from the mixer and accordingly operating an electric motor 17 driving the extruder. extruder 9 has a meter 36, of

    power metering drive. n / nln torque, and / or pressure g, extruder. The measured moths enter the governing body 13.
    This body acts on the executive electrode of the discharge valve 12 and / or the natural motor 17 of the extruder 9.
    Following the extruder 9, a cooling bath 37 is installed behind the nozzle 21, in which the first conveyor belt 38 is placed and the second transport belt 39 is slightly offset from it. The first belt is a rubber conveyor belt on which the molded parts 21 coming from the nozzle are cooled. These parts are still unstable in form and require an undergrowth, formed by rubber or steel tape 38. At last, the continuous bars are cut using a cross-cutting mechanism 40 into briquettes. Following this, the molded parts are fed to a second conveyor belt 39 having recesses and made in the form of a lattice belt. This allows cooling of the parts and the bottom.
    In the proposed device, the molding is carried out in an extruder separated in place from the kneader. The mixing and kneading processes are developed with molding, due to which the throughput of the mixer increases significantly and the process efficiency also increases. It is possible to simultaneously extrude a larger number of smaller bars with a different cross section. With increased mass viscosity, processing in a multi-shaft extruder can be carried out without difficulty.
    The discharge valve 1C in the connecting shaft forms a transfer member and is first brought into the unloading position when the process starts. Then, the shutter 10 is re-arranged in such a way that the discharge opening 11 remains closed. This allows additional protection to be established if the consumed torque in the extruder exceeds the allowable limit. In this case, a torque sensor is placed on the extruder shaft as a measuring device 36, which, through control 13, is connected to the test motor 12 for the discharge valve 10. If the formulation is inadmissible from the specified composition due to an accidental excessive dosage of coke or a decrease or cessation of supply of pitch the viscosity and thus the torque in the mixer increases. The torque measurement device 36 detects an unacceptable increase and, through the control body 13, ensures the long opening of the valve 10, as a result of which the incompatible amount of material is withdrawn from the process.
    The control of the extruder shafts 29 can also be combined with the control of the discharge valve 10. In this case, an additional effect of the control 13 on the drive motor 17 occurs due to the connection 41.
    The speed of the extruder shafts 29 is controlled by the level element 35 in such a way that, when a given level of material is reached in the connecting shaft 7, it is increased through the electric motor 17 and thus the productivity of the extruder is improved. The speed of the extruder shafts is controlled at the inlet of the gearbox.
    Chamber 8 is made in double stacks, with the internal volume of the chamber being heated or cooled, and the sections can be independent of each other circulation circuits for a heated or cooled medium. Due to the fact that the chamber consists of two parts, it is possible to clean and maintain the internal volume of the chamber and the worm shafts.
    The extruder, designed as a separate unit, can be moved on wheels, which greatly simplifies maintenance.
    The installation can be automatic and remotely controlled.
    On the example of the composition of the mixture of the source material consisting of 60-80% coke with a grain size of 0-15 mm and 20-40% of pitch, the proposed device allows preparing a mass for molding and forming an electrode mother
