Description

Изобретение относитс к устройствам, примен емым в области производства алюмини электролизом дл механизации технологических операций.The invention relates to devices used in the field of aluminum production by electrolysis for the mechanization of technological operations.

Известна машина дл обслуживани электролизеров с обожл енными анодами, включающа механизм передвижени машины и рабочие органы с приводами 1.A known machine for servicing electrolyzers with burned anodes, including a mechanism for moving the machine and working bodies with drives 1.

Недостатком этой машины вл етс отсутствие устройства, которое механизировало бы такую трудоемкую операцию, как очистка места под обожженный анод от кусков электролитной корки, пены и кусков анода.The disadvantage of this machine is the absence of a device that would mechanize such a time-consuming operation as cleaning the place under the burnt anode from pieces of electrolyte peel, foam and pieces of anode.

Цель изобретени - повышение производительности и улучшение условий труда.The purpose of the invention is to increase productivity and improve working conditions.

Это достигаетс тем, что предлагаема машина снабжена устройством дл расчистки места под анод, выполненным в виде подъемно-поворотной стрелы с перфорированным ковшом.This is achieved by the fact that the proposed machine is equipped with a device for clearing the space under the anode, made in the form of a lifting-swivel boom with a perforated bucket.

Применение толстостенного ковша в данном случае недопустимо ввиду инерции теплопередачи через толстую стенку. За врем черпани внутренние слои толстой стенки не успевают прогреватьс до температуры расплава, а после выхода ковша из расплава жидкий металл, оставшийс в ковше.The use of a thick-walled bucket in this case is unacceptable due to the inertia of heat transfer through a thick wall. During the scooping period, the inner layers of the thick wall do not have time to warm up to the melt temperature, and after the ladle leaves the melt, the liquid metal remaining in the ladle.

быстро охлаждаетс до те.мпературы затвердевани из-за теплопередачи от наружных слоев стенки, отбираюпдих тепло от жидкого металла, к более холодным внутренним, при этом застывший металл «приклеивает мелкие куски материала и пену к ковшу, после чего этот материал необходимо оттуда выколачивать. Равномерно прогретый в расплаве тонкостенный ковш, наоборот, отдает тепло охлаждающемус на возду.хс металлу , что способствует более полному удалению жидкого металла через отверсти ковша , а образующа с при этом весьма тонка пленка застывшего на ковше металла легко )тстает от него вместе с материалом, извлеченным из расплава.cools down rapidly due to heat transfer from the outer layers of the wall, extracts heat from the molten metal to the colder inner ones, while the frozen metal "sticks" small pieces of material and foam to the ladle, after which the material must be extorted from there. The thin-walled ladle, uniformly heated in the melt, on the contrary, gives off heat to the metal on the air, which contributes to a more complete removal of the molten metal through the holes of the ladle, and the very thin film of the metal hardened on the ladle easily gets rid of it, extracted from the melt.

Поскольку при замене анода на электролизере , кроме расчистки места под новый анод, необходимо произвести зачистку контактной поверхности ошиновки, описываема машина оборудована устройством дл зачистки оплиновки, включающим торцовую н.1етку с нриводами подъема, подачи и вращени .Since when replacing the anode on the electrolyzer, in addition to clearing the space for the new anode, it is necessary to clean the contact surface of the busbar, the described machine is equipped with a device for stripping the molding, which includes a face cable with a hoist, feed and rotation direction.

Claims

Using lightweight floor-standing machines, one or two process steps, it is advisable to create a time reserve of usually overloaded heavy crane or gantry machines that carry out complex mechanization of electrical services; 1 of them with burnt anodes. FIG. 1 shows the proposed machine, side view; in fig. 2 - wedge connection of the bucket with the lever; in fig. 3 shows a section but A-L in FIG. 2. Transport base of the maschina in v. 1 electric lift truck 1, in which the forklift is replaced by a mounting plate

2. To the lower part of the plate 2 through the electrically powered spacer kreyits mechanism 3 rotate the boom 4. In the case of the rotation mechanism on podkroschpnipniki installed shaft-gear, the upper end of which is a brass 5 with two eyelets. The gear of the racer is engaged with the toothed rack cut on the hydraulic cylinder 6 rod. To the bracket 5, the boom 4 is attached to the hinge hydraulic cylinder 7 so as to raise and lower it. At the second end of the boom 4, the lever 8 is pivotally mounted. It is connected to the hydraulic attachment HJTOKOM 9. A perforated bucket 10 made of nonmagnetic heat-resistant steel is turned to the lever 8. The wedge lugs of the sleeves 11 of the bucket 10 are inserted; 1eni into the corresponding grooves of the hub 12 of the lever 8, and a wedge 13 is hammered into the slot of the lever 8. The control of the hydraulic cylinders of the working bodies is carried out from the spool section, which is located on the loader. To protect1) 1 operator maschna from tenlo 1K1 beam and electrolyzer operator's place is closed for | Ts1gtnym screen 17. Manjnna works in the following way. Before installing the new anode in the electrolyzer, the magnin drives up in front of the anode. In the transport position, the boom 4 is raised up. KOVSH-10 is turned to the arrow 4, the brush 15 is raised to the upper position. Clearing the space for the anode is carried out by moving the breakthrough 4 and the lever 8 with the help of hydraulic hydraulics 6, 7 and 9, similar to those of an excavator, working on the principle of "reverse shovel. After clearing the space for the anode, the contact surface of the busbar 16 is provided. in the zone of strong thermal radiation and abundant B1) 1 separated gas from the electrolyzer. Therefore, the expected positive effect from the introduction of the invention is to reduce the share of manual labor, increase productivity and improve sanitary and hygienic working conditions when servicing electrolyzers with baked anodes. Claims of the invention A floor mashina for servicing electrolyzers with burned anodes, including a machine movement mechanism and actuating bodies with drives, in order to increase productivity and improve working conditions, it is equipped with an area meter for clearing the anode space, made in lifting and turning Etrela with perforated forging.
