Abstract

FIELD: electrical engineering. SUBSTANCE: scrap is separated in advance into sections, insulation layers of ties are broken. For complete separation of insulation from metal scrap is directed into perforated tumbling drum with longitudinal ribs where tumbling and separation with simultaneous separation of insulation scrap into large and small fraction are performed. EFFECT: enhanced operational efficiency.

Description

Изобретение относится к электротехнике. The invention relates to electrical engineering.

Известен способ переработки кабельных отходов с токопроводящими жилами и термопластичной изоляцией, включающий вальцевание отходов для разрушения изоляции, измельчение в роторном измельчителе и сепарирование в воздушном сепараторе. A known method of processing cable waste with conductive cores and thermoplastic insulation, including rolling waste to break the insulation, grinding in a rotary grinder and separation in an air separator.

Недостатками известного способа являются невысокое качество очистки отходов и низкая производительность. The disadvantages of this method are the low quality of waste treatment and low productivity.

Целью изобретения является повышение эффективности процесса переработки отходов обмоток мощных электродвигателей и трансформаторов. The aim of the invention is to increase the efficiency of the waste recycling process of windings of powerful electric motors and transformers.

Для достижения цели отходы предварительно разделяют на отрезки, отделение изоляции от жилы производят шинкованием с последующей галтовкой и в процессе сепарирования отходы изоляции разделяют на фракции. To achieve the goal, the waste is preliminarily divided into segments, the insulation is separated from the core by shredding, followed by tumbling, and during the separation process, the isolation waste is divided into fractions.

П р и м е р. Осуществляют переработку отходов обмоток мощных электродвигателей 4РТ, РТ, 406 с изоляционным покрытием стеклотканью, слюдой, полиэтиленом и т.п. толщиной 2-3 мм. Отходы подвергают рубке на аллигаторных ножницах длиной 250-300 мм. Отрезки для разрушения общих слоев изоляции шинок пропускают через шинковочный станок. Для полного отделения изоляции от металла отходы направляют в перфорированный галтовочный барабан с продольными ребрами. Крупная фракция изоляции площадью от 5 мм2 и выше проваливается через перфорацию барабана в приемный бункер, а более мелкая удаляется вытяжкой с последующей очисткой в рукавных фильтрах с циклонами.PRI me R. They carry out the recycling of the windings of powerful 4RT, RT, 406 electric motors with an insulating coating with fiberglass, mica, polyethylene, etc. 2-3 mm thick. Waste is chopped on alligator scissors 250-300 mm long. The segments for the destruction of the common layers of insulation of the tires are passed through a shredder. To completely separate the insulation from the metal, the waste is sent to a perforated tumbling drum with longitudinal ribs. A large fraction of insulation with an area of 5 mm 2 and higher falls through the perforation of the drum into the receiving hopper, and a smaller fraction is removed by extraction, followed by cleaning in bag filters with cyclones.

Данный способ позволяет перерабатывать более 1 т отходов в смену при двух рабочих. Очищенный металл совершенно не содержит остатков изоляции и готов к переработке. Способ экологически чист. This method allows you to process more than 1 ton of waste per shift with two workers. The refined metal does not contain any residual insulation and is ready for processing. The method is environmentally friendly.
