SU918337A1 - Flow line for lining cathode assemblies of aluminium electrolyzers - Google Patents

Description

one ; :; . The invention relates to the production of aluminum, in particular, to auxiliary equipment for performing assembly and assembly work when assembling new cathode devices or for their capital repairs. At present, in aluminum smelters, the lining of cathode devices is made at the ends of the electrolysis building, h similar to the technical essence and the achieved effect. It is the production line of the lining of the cathode devices, which includes the cargo carriages in the channel for installation of the cathode sections, moving winches with an open-loop cable, on the working wire, whose loop has a loop for mooring the load trolley, and installed above the channel along the process flow, there is a device for laying cathode sections, an overlaying machine, a heating device, a device for stuffing the bottom seams and an installed suction umbrella at the end of the line is a stationary welding station. The line is equipped with lugs for feeding lining materials to lining production sites. The transport of kubels and drums with an unfolded bottom mass is carried out by an overhead crane l. The disadvantages of this line are labor-intensive manual operations in the production of lining works (filling of chamotte chips and bottom mass); manual operation of mooring cargo carriages for the transporting device; significant dust and gas emissions worsening working conditions. The purpose of the invention is to reduce labor-intensive manual operations and improve working conditions. The goal is achieved by the fact that the flow line additionally

equipped with a device at the beginning of the line for filling and uniform distribution of lining materials on the bottom of the cathode device, made in the form of a bunker equipped with a slit-like chute, and the bunker is mounted on the movable portal with the possibility of vertical movement.

The production line consists of a trolley 1 installed in the channel, moving along rails 2 by means of a device 3 for moving a cargo trolley and a winch 4 with an infinitely closed cable 5 enveloping the revolving unit 6, and arranged above the channel sequentially along the process of the device 7 for filling and uniform distribution of lining materials on the bottom of the cathode device 8, kyubeli 9 for feeding lining materials, device 10 for laying the cathode sections and rolling machine us 11 mounted under the umbrella gazootsasyvayuschim 12, heating device 13, the device for loading mass and of the bottom device 15 to hearth stuffing sutures installed under the umbrella gazootsasyvayuschim 16 welding station 17, installed in the end of the line.

Flow line works as follows. ,

The trolley 1 interlocks with the device 3 to move them along technological positions with an automatic gripper 18 mounted on the trolley 1 perpendicular to the device 3.

The automatic gripper 18 consists of a two-arm lever 19, a leash 20 with a counterweight 21, hinged in pairs on the same axis 22, and stops 23 rigidly mounted along the trolley 1 on the outside of the double-arm levers 19.

The trolley 1 is equipped with pairs of skates, located under the supporting platforms 25, four rows of rollers 26 are installed to facilitate installation of the load carrying beams (not shown), and removable cables 27 are used to collect waste materials.

The device for filling and uniform distribution of lining materials at the bottom of the cathode device 8 consists of a hopper 28 equipped with a slit-shaped chute 29 with a gate 30 mounted for vertical movement on the movable portal 31 located on the rails 32.

The welding station for welding the flange sheet is made in the form of a movable portal 33 mounted on rails. On the monorail 35 of the portal 33 trolleys 36 are installed, on which rods 37 are rigidly fixed.

At the bottom of the rods 37, welding machines 38 and swivel chairs 39 for welders are installed. In the middle of the rods 37, there are gas suction tubes 0, equipped with gas suction umbrellas C} and a light shield 2.

Gas suction units 0 are combined into a common gas suction system +3, ending with a shaft-shaped tip C, which is passed into the cavity of box-shaped channel 5 through separating-sealing groove k6.

The continuous line is connected to the electrical system, which provides remote control of the movement of cargo carts with cathode devices mounted on them.

For lining operations, the One crane is shown) a load trolley 1 is installed at the beginning of the line with support ramps 24 on rails 2.

Claims (2)

The cathode device 8 is installed on the supporting platforms 25 of the cargo trolley 1 by means of a bridge crane. Then, a filling device 7, filled with chamotte grit, hopper 28 of the filling device 7 is set at a predetermined height, the shutter 30 of the slit-shaped chute 29 and the portal 31 are mounted over the cathode device 8. along the cathode device 8, the bottom of the cathode device 8 is evenly filled with chamotte grit. Next, the filling device 7 is rolled back to its original position, and the trolley 1 with the cathode device b is moved to the next technological position. The trolley V is moved by a winch by automatically engaging the gripper 18 of the trolley, with a device 3 for moving the trolleys attached to the working branch of the infinitely closed rope 5 of the winch L. Then, using a bridge crane, brick is placed in the tube 9 at the bottom of the cathode Devices 8. On the prepared bricklaying, a hot bottom mass is laid and rolled with a knurling machine 11, and gases released from the bottom mass are collected under umbrella 12 and removed to the gas cleaning system. At the end of the operation, the cargo trolley 1 with the cathode device 8 is moved under the umbrella 16, where the heating device 13 heats the grooves (joints) between the cathode sections . Heated to a predetermined temperature, the grooves poured the bottom mass with the help of the device H for loading the bottom mass, and with the help of the device 15 for filling the bottom seams the bottom seams are sealed, and the gases released from the bottom mass are sucked into the gas cleaning system. Then, the cargo trolley 1 with the cattle-cattle device 8, which is enlarged, is moved to the last technological position, at which the flange plate is welded around the perimeter of the cathode device 8 by welding combines 38 installed on the sliding portal 33. The gases emitted during the welding with gas-suction umbrellas tl are removed into the gas cleaning system. Upon completion of the work, the lined cathode device 8 is directed to the electrolysis housing, and the truck, which is released from the trolley 1, is installed at the beginning of the line on the rail with s. 2.
