Description
жидкого металла в плавильную печь. Верхн часть трубы 7 имеет утолщение 8 с кольцевой проточкой 9, в которой помещен ферромагнитный сердечник 10. Трубы 4 и 7 изготовлены из огнеупорного материала, а сердечник 10 покрыт снаружи слоем огнеупора 11. Внизу труба 7 изогнута в виде колена и введена в камеру печи 1. На трубу 4 надета катушка 12 переменного тока, охваченна магнитопроводом 13. Зазор между трубами 4 и 7 в пределах, ограниченных верхним и нижним основани ми магнитопровода 13, образует кольцевую активную зону насоса 14. В нижней части активна зона разделена вертикальными перегородками из диэлектрика 15.Установка работает следующим образом. liquid metal in a smelting furnace. The upper part of the pipe 7 has a thickening 8 with an annular groove 9 in which the ferromagnetic core 10 is placed. The pipes 4 and 7 are made of refractory material, and the core 10 is covered outside with a layer of refractory 11. At the bottom the pipe 7 is bent in the shape of a knee and inserted into the furnace chamber 1 The tube 4 is equipped with an AC coil 12 enclosed in the magnetic conductor 13. The gap between the pipes 4 and 7 within the limits of the upper and lower bases of the magnetic conductor 13 forms the annular active zone of the pump 14. In the lower part the active zone is divided by vertical fr rodkami dielectric 15.Ustanovka operates as follows.
В камере печи 1 предварительно наплавл ют ванну жидкого металла с таким расчетом , чтобы конец трубы 4 оказалс погруженным в нее. Заполн ют активную зону насоса 14 жидким металлом, например путем создани в ней разрежени , после чего на зажимы катушки 12 подают напр жение. Насос поднимает жидкий металл, который, достигнув смесительной камеры 6, попадает в трубу 7 и самотеком направл етс в камеру печи 1.In the chamber of the furnace 1, a bath of liquid metal is preliminarily deposited so that the end of the pipe 4 is immersed in it. The core of the pump 14 is filled with liquid metal, for example, by creating a vacuum in it, after which a voltage is applied to the terminals of the coil 12. The pump lifts the liquid metal, which, having reached the mixing chamber 6, enters the pipe 7 and flows by gravity into the furnace chamber 1.
Непрерывна циркул ци металла происходит по пути, указанному на чертеже стрелками: выносной карман - подающий каналсмесительна камера - канал подачи стружки и жидкого металла - печь.Continuous circulation of metal occurs along the path indicated by arrows in the drawing: portable pocket - supply channel; mixing chamber - channel for supplying chips and liquid metal - furnace.
Через загрузочную воронку 5 в смесительную камеру 6 подаетс стружка. Циркулирующий жидкий металл подхватывает ее, обволакивает и увлекает в трубу 7, и, далее , в ванну печи. Одновременно происходит нагрев и плавка стружки и перемешивание ванны жидкого металла.Chip is fed through the feed hopper 5 into the mixing chamber 6. The circulating liquid metal picks it up, envelops and drags it into the tube 7, and, further, into the bath of the furnace. At the same time, the chips are heated and melted and the bath of liquid metal is stirred.
Оптимальный режим работы установки задаетс путем регулировани те.мпературы металла в печи, производительности насоса и скорости подачи стружки.The optimum mode of operation of the plant is set by adjusting the temperature of the metal in the furnace, the pump capacity and the chip feed rate.
Сокращение до минимума рассто ни , на которое перемещаетс жидкий металл от ванны до смесительной камеры, полна изол ци жидкого металла и плав щейс стружки от контакта с атмосферой, комп.актность и простота конструкции установки сокращает потери металла, тепла и электроэнергии , повышает надежность и безопасность установки. Узел, объедин ющий насос, металлопровод ,. смесительную камеру и загрузочную воронку, в случае выхода из стро , может быть легко и быстро заменен без перерыва в работе печи.Minimizing the distance that the liquid metal moves from the bath to the mixing chamber, complete isolation of the liquid metal and melting chips from contact with the atmosphere, the compactness and simplicity of the installation design reduces metal losses, heat and electricity, increases reliability and safety. installation. The knot uniting the pump, metal pipeline,. the mixing chamber and feed hopper, in the event of a malfunction, can be easily and quickly replaced without interrupting the operation of the furnace.
