Description
УСТРОЙСТВО дл очистки РАСПЛАВЛЕННОГО МЕТАЛЛАDEVICE for cleaning MELTED METAL
Изобретение отпоситс к устройствам дл очистки расплавленного металла от загр знений и может быть использовано при изготовлении листового стекла на поверхности расплавленного металла.The invention relates to devices for cleaning molten metal from contamination and can be used in the manufacture of sheet glass on the surface of the molten metal.
Известно устройство дл очистки расплавленного металла, используемого нри изготовлении листового стекла, содержащее .карман, примыкающий к ванне с металлом и сообщающийс с ней каналами.A device for cleaning molten metal used in the manufacture of sheet glass, containing a pocket adjacent to the metal bath and communicating with it through channels, is known.
Цель изобретени - повыщенне качества очистки.The purpose of the invention is to increase the quality of cleaning.
Достигаетс это чем, что карман выполнен цилиндрическим, снабжен установленной по его и,ентру трубой дл сбора загр знений, сообщающейс с бункером, « размещен в магнитопроводе с обмоткой.This is achieved by the fact that the pocket is cylindrical, equipped with a collector installed along it and, to the center, for collecting contaminants communicating with the bunker, "placed in the magnetic circuit with a winding.
Дл управлени питанием обмотки устройство снабжено реле времени, а дл отвода очищенного металла - кольпевым желобом, установленным в верхней части кармана.For controlling the power supply of the winding, the device is equipped with a time relay, and for removal of the cleaned metal - with a collet chute installed in the upper part of the pocket.
На чертеже изображено предлагаемое устройство , общий вид.The drawing shows the proposed device, a General view.
Устройство содержит примыкаюи.1.ий к ванне с металлом герметичный дилиндрический карман 1, сообщающийс с ванной каналом 2 дл подачи металла 3 на очистку. По центру кармана установлена труба 4 дл сбора загр знений , сообщающа с с бункером 5, а в верхней части кармана смонтирован кольцевой желобThe device contains, adjacent to the metal bath, a sealed dilindrical pocket 1 communicating with the bath channel 2 for supplying the metal 3 to the cleaning. In the center of the pocket is installed a pipe 4 for collecting contaminants, communicating with the hopper 5, and in the upper part of the pocket an annular groove is mounted
6 дл сбора чистого металла 7. Вокруг кармана 1 с небольшим зазором размещен магиитопровод 8 с обмоткой 9 трехфазного тока. В схему питапи обмотки включено реле времени дл уменьщени нлн нолного отключени тока через определенные нромежуткн временн. Обесточенный расплавленный металл (Поступает под напором из канала 2, в карман до уровн А. В это врем труба 4 герметично закрыта . Зате1 включают ток, в результате чего создаетс бегущее магнитное поле, которое увлекает за собой жидкий .металл, привод его во вращение. При этом поверхность раснлаъленного металла представл ет собой параболлоид 10 вращени . Из-за разности в удельном весе чистый металл, как .более т желый, отбрасываетс 1К стенкам кармана, более легкие загр знени 11 собираютс в центральной зоне.6 to collect pure metal 7. A magic pipe 8 with a 9-phase three-phase winding is placed around pocket 1 with a small gap. A time relay is included in the circuit of the winding circuit for reducing the current by turning off the current through certain time intervals. De-energized molten metal (It flows under pressure from channel 2 to the pocket up to level A. At this time, pipe 4 is hermetically sealed. Then 1 turns on the current, resulting in a traveling magnetic field that carries the liquid metal and drives it into rotation. In this case, the surface of the de-bonded metal is a parabolloid of rotation 10. Due to the difference in the specific gravity, the pure metal, as heavier, is dropped 1K to the pocket walls, the lighter soils 11 are collected in the central zone.
В обмотке 9 устанавливают ток такой силы, при которой чистый металл 7 нерелнваетс через верхнюю кромку карлгана 1 в кольцевой желоб 6, а в центре кармана уровень металла устанавливаетс ниже верхнего конца трубыIn the winding 9, a current of such a force is established at which the pure metal 7 does not rest through the upper edge of the carlgan 1 into the annular trough 6, and in the center of the pocket the metal level is set below the upper end of the pipe
4. Накопнвщись выше верхнего уровн трубы, загр знени осьтаютс в бункер 5. Дл сброса всех загр знений нри помощи реле времепи кратковременно уменьщают или полностью отключают ток в обмотке, при этом уровень4. Accumulate above the upper level of the pipe, contamination flows into the hopper 5. To reset all contaminations, the time relay briefly reduces or completely cuts off the current in the winding, while the level
пунктирной кривой Б, в результате чего все загр знени с небольшим количеством металла постунают в бункео 5.dashed curve B, as a result of which all contaminations with a small amount of metal are deposited in bunkeo 5.
