    The invention relates to devices used in electrolysis shops for the production of aluminum.
    The aim of the invention is to improve the performance and reliability of the device.
    Replacing the anodes in the electrolysis baths without performing accurate preliminary measurements of the position of the new anode with respect to the worn-out one, allows one to correct its position after removing the worn-out anode.
    The invention consists in that in a device having the form of a cage fixed on a bridge crane of a known type, which is usually found in the electrolysis shop, there are additionally two horizontal flat beds protruding in mutually opposite directions away from the open base of the module, In this case, on each side of the flat bed, at least one sliding slide is mounted, which extends inside said open base of the module and serves to hold at least one new and one of the worn anodes. The device also contains a control cabin for the operator and a symmetrically positioned alumina hopper, at least one retracting positional element having a fork shape or a similar shape protruding from the side of said stand and having a means of attaching to the anode side of the anode busbar. the rod of the adjacent anode, which serves to ensure that the module is precisely positioned before being placed in the furnace, thanks to which the worn anode is removed and a new one is installed, while the module is held in an unchanged position. position; a carriage sliding along the horizontal guides protruding from the top of the cage in the direction perpendicular to the direction of movement of the said duo holder, and having a lever which is telescopically protruding in the vertical direction
    and holds the known means for unscrewing and fixing the anode rod on said anode bus, as well as suitable means for gripping and lifting this anode, while the carriage can be moved, thereby returning the worn anode to a central position inside the cage and then placing it on the holder coming from a flat bed; cutting the electrolyte crust (crusher) on the retractable telescopic arm; a device for cleaning the top surface of a worn anode; and a device for cleaning a cavity using a worn anode.

    IN LYN.
    The device for replacing the anodes is a multifunctional module, which is made in the form of a stand formed by four vertical posts 1.1 a, 1c (the fourth stand is not visible) fastened at the top with horizontal straps 2, due to which a structure similar to the box is formed having open side walls and floor. Two flat beds 3 and 3a, which are coplanar and located symmetrically relative to the central axis of the stand, are attached to a pair of pillars 1-1b and 1a-1c (the latter is not visible). Holders 4 and 4a are located on each of the above-mentioned flat beds 3 and Za, which can be moved inwards to the central part of the stand, as shown by short dashed lines and indicated by 4c in Fig. 1.
    These holders serve to hold and move new and worn anodes into and out of the center area of the cabin. On each holder 4 and 4a there is a vertical stand 5 and 5a, at the upper end of which there is a locking means 6 and 6a of a known type, which serves to fix and hold the anode rod 7 (Fig. 7).
    A cab 8 for the operator is located laterally and offset relative to the movable holders 4 and 4a, and on the opposite side is a bunker 9 containing alumina to cover the new anode after it has been positioned with the oriented nutrient hose 9a.
    A telescopic arm 10 with a crusher 11 of a known type is mounted in front of the flat bed 3. This lever is attached to the flat bed so that it can move from the initial position 10 (FIG. 3) to the working position 10a. At the bottom inside of the cage, another telescopically operating lever 13 (Fig. 2) is suspended at point 12, to which a rotary plug or knife 14 is attached, which serves to clean the bath after removing the worn anode (Fig. 9).
    In the initial state, the lever 13 of the scraper 14 is retracted and is in the position shown in Figs. 1 and 2, while in the working position it is moved to position 13a-14a (Fig.9).
    In the lower part of the cage there is also a telescopic one. a lever which is located parallel to the telescopic lever of the Yua crusher; a scraper or a knife is located at the free edge of the said telescopic lever. It is used to clean the top surface of the worn anode from
    residues of the crust falling into the bath, due to which it is possible to get rid of a significant number of labor-intensive operations to work with the remnants of the contents of the bath, which
    must be replaced.
    In the proposed device, the solidified solution is added to the same bath from which it is obtained, which prevents a change in the composition of the bath when using such special additives as lithium, magnesium and the like.
    Inside the upper inside of the cage there is a carriage 15 driven by a motor that can be moved along
    5 guide rails 15a, protruding outside the cage in a direction perpendicular to the feed direction of the anode holders 4 and 4a. To this trolley 15 is attached a lever 16, which is telescopically
    0 is pulled out and adjusted. A device 17 is attached to the lower part of said lever 16, which serves to grip, unscrew and lift the anode rod 7 to remove it from the anode busbar,
    5 The pick-up and lift-up device 17 begins to work, when the module is positioned side by side with the electrolyzer in a precisely defined and stable position d / s, the new anode was installed exactly at the same
    0 is the position in which the botanical anode was located.
    With the help of two hydraulically controlled plugs 18, the module is positioned relative to the electrolyzer.
    5 19 (figure 4, 5, 9 and 10). they are oriented by rotating around the hinge 20 in the upper right part of the module, and their free ends are moved by displacing the module along the height of the electrolyzer, along and perpendicularly fixed position on the anode bus 21 and on the anode bus of the adjacent anode. Consequently, the height of the module is determined by the location of the fork element on the bus 21. And its lateral displacement, i.e. the location relative to the adjacent anode is determined using a fork-shaped gasket in contact with the rod of the said adjacent anode.
    0 After the module is finally positioned, the cart 15 with the unscrewing, removing and lifting anode can perform the operations of removing the spent anode and installing the new anode in exactly
    5, the same position as the spent anode.
    The module of the described construction with an anode replacement device and auxiliary devices is equipped with a means of suspension to a conventional bridge crane, already
    available in the workroom. For this purpose, a cylinder 22 (figure 2) is connected to the upper crosspiece 2, which can slide along a cylindrical guide 23, the upper surface of which is flat for mating with a protrusion 24. integral with the carriage 25 sliding along the rails 26. The latter are made on the basis of A conventional bridge crane (not shown) is perpendicular to the direction of movement of this bridge crane. A crane 27 is mounted on platform 25, to the hook 28 of which an upper edge of said cylinder 22 connected to the module is attached.
    To give the module stability against lateral oscillations during the movement of the bridge crane, the cylinder 23 is provided with four peripheral pins 29, which can enter into the protrusion 24, which is integral with the carriage 25. Therefore, when. During operation of the crane 27, the cylinder 22 slides by the telescopic method inside the cylinder 23 connected to the base of the carriage 25, whereby the module can be raised or lowered to the required level when performing replacement operations of the spent anode with a new one.
    Thus, the module can perform three types of movement in space: an up-down movement in the vertical direction provided by the crane 27 of the carriage 25, a movement in the longitudinal direction, parallel to the anodes of the bath using an overhead crane and movement perpendicular to the anodes by the carriage 25 on a bridge crane, perpendicular to the direction of travel of said bridge crane.
    The module suspension system to the overhead crane trolley also compensates for all possible installation errors. The telescopic bench also contains a device for turning the module through 180 °, due to which the module can work on both sides of the electrolyzer. Moreover, a protection system of a known type can be installed; it is necessary when the module is moved inside the side spans without collisions.
    The proposed module can be supplemented with two racks 30 (fig. T-2), which can be lowered down in the working position of the module, stabilizing it during working operations.
    The use of the module and the sequence of operations for replacing the anode are described below with reference to FIGS. 3 through 11, which show the replacement of a worn or used anode 31 with a new anode 32.
    The bridge crane is initially located above the module, and a power cable (not shown) is connected to it, which serves to switch on the various devices that are in the module; it is assumed that the new anode 32 is already on the module, on the side holder 4a, while the anode rod is fixed by the device 6a. The module is suspended from a trolley 25 and raised, cylinder
    0 23 is close to the plane of the protrusion 24, made integral with the trolley 25. When performing this stage, the rack 30 holders are retracted or folded.
    Then using a bridge crane and
    5, the carriage 25 disposed thereon is installed near the electrolytic cell, while the rails 15a of the carriage 15 are arranged perpendicular to the row of anodes (Fig. 3). The operator in the control cabin 8
    0 moves the carrying lever of the crusher down from the initial position 10 to the working position 10a (Fig. 3) and then under the influence of the telescopic lever 10 the crusher 11 is located on the opposite side
    5 of the removed anode (not shown) and breaks the crust at this angle; then, by displacing the bridge crane and the module, the crusher 11 moves in front of the anode 31, thereby crushing the crust along the outer leading edge of the same anode. The module moves to the end position with respect to the flax of the furnace (Fig. 4). This position is determined by lowering the plug 18 onto the anode bus 21 and contacting it with
    5 this bus. The exact position fixing is determined by the location of the anode rod near the spent anode, to which the second plug is attached, to the height of the anode bus 21 and by fixing
    0 remove the module from the same anode bus 21. Then the carriage 15 is moved from the initial position to the outward position 15c (Fig. 5), the telescopic lever 16 is lowered, and the assembly 17 is equipped with a gripping and unwinding device gripping and unwinding the latch anchor 7 (Fig.5).
    The position of block 17 is determined by
    0 machically on command with plug 18 and anode bus 21.
    When the anode rod is detached from the holder and held by the lever 16 with a pusher, the spent anode 31
    5 emerges from the bath under the action of the striker 17a connected to block 17. The device also holds the anode rod 31 and by raising the lever 16 and returning the carriage 15 from position 15a to the stopping position inside the module, the anode 31 moves to
    the hole between the two flat beds 3 and 4a and stops inside the module, in which the holder 4 receives the worn anode 31 by moving the flat bed to the upper position.
    In Fig. 6, the anode 31 is shown inside the module, and Fig. 7 shows the anode located on a holder in an isolated position, in which axis 7 is fixed by device 6.
    After the spent anode is removed from the bath and before this anode is lifted by the lever 16, a device for cleaning the upper surface of this anode is activated, which under the action of the telescopic lever 33 moves towards the scraper 34 and contacts the anode until then. until it reaches position 34a (Fig. 8). After removal of the spent anode, a foam remover equipped with a fork or knife begins to work, the position of which is regulated by a telescopic lever 13, which cleans the surface freed by the spent anode, and when the cleaning is completed, this device is moved back to its original position (Fig. 8).
    The new anode 32 is moved with the help of its holder 4a in the center of the module in the position specified by the lever 16 of the upper carriage 15, to the same height relative to the initial plane on which the spent anode is located; lever 16 installs a new anode 32 inside the bath and then screws it onto a holder that secures the anode rod 7a to the anode bus 21. Consequently, there is no need for precise adjustment operations.
    When the new anode is installed in the final position (Fig. 10), start, t work the bunker 9 (Fig. 11), which with the help of hose 9a coats the new, located in the right place, anode 32. Then the module using a bridge the crane is moved to the place from which the spent anode is to be removed and into which a new anode is to be placed,
    In the initial state, the module is located on a trailer or on a self-propelled trolley of a known type (not shown). Moreover, the proposed module can contain two pairs of anode holders 4-4a, with which two new anodes can be placed on the module, and two spent anodes can be removed from the electrolyzer using fewer working steps.
