Description

Изобретение относится к разделению материалов по электропроводности и ' может быть использовано при вторичной переработке металлов. $The invention relates to the separation of materials for electrical conductivity and can be used in the recycling of metals. $

ЦеЛь изобретения - повышение эффективности извлечения электропроводных частиц за счет разделения смеси на два потока.The aim of the invention is to increase the efficiency of extraction of electrically conductive particles due to the separation of the mixture into two streams.

На чертеже показан сепаратор, об- эд щий вид в плане с частичным вырывом ленты конвейера и обечайки индуктора» Электродинамический сепаратор содержит загрузочное приспособление (не показано), ленточный конвейер 1, эд под которым расположен индуктор 2 вращающегося магнитного поля в виде ролика, на поверхности которого вы-> полнены расположенные по винтовой линии пазы с размещенными в них по- 20 стоянными магнитами чередующейся полярности. Под индуктором расположен разгрузочный бункер 3 для элек- тропроводных частиц. Сепаратор содержит также бункер для неэлектропровод-25 ных частиц (не показан).The drawing shows a separator, obedinaya plan view with a partial tearing of the conveyor belt and the shell of the inductor "Electrodynamic separator contains a loading device (not shown), a conveyor belt 1, under which there is an inductor 2 of a rotating magnetic field in the form of a roller, on the surface which -> the grooves located along the helix with the permanent magnets of alternating polarity placed in them are made. Under the inductor is a discharge hopper 3 for electrically conductive particles. The separator also contains a hopper for non-electrically conductive particles (not shown).

Индуктор 2 вращающегося магнитного поля расположен так, что его ось вращения перпендикулярна продольной 30 оси конвейера, и выполнен из двух симметричных относительно продольной оси конвейера частей, которые отличаются друг от друга направлением навивки винтовой линии, по которой рас--эд положены пазы.The inductor 2 of the rotating magnetic field is located so that its axis of rotation is perpendicular to the longitudinal axis of the conveyor 30, and is made of two parts symmetrical with respect to the longitudinal axis of the conveyor, which differ from each other by the direction of winding of the helix along which the slots are placed.

Сепаратор работает следующим образом.The separator works as follows.

Исходная смесь подается лентой конвейера 1 в зону действия вращающегося магнитного поля, создаваемого индуктором 2. Это поле наводит в электропроводных частицах вихревые токи. В результате взаимодействия вращающегося магнитного поля с магнитным полем вихревых токов возникает электродинамическая сила, выталкивающая электропроводную частицу по направлению, перпендикулярному к пазам индуктора. Под действием этой силы поток электропроводных частиц разделяется на два потока. В результате путь, проходимый электропроводной частицей, уменьшается, что повышает качество электропроводной фракции.The initial mixture is fed by a conveyor belt 1 into the zone of action of a rotating magnetic field created by inductor 2. This field induces eddy currents in electrically conductive particles. As a result of the interaction of the rotating magnetic field with the magnetic field of the eddy currents, an electrodynamic force arises, pushing the electrically conductive particle in the direction perpendicular to the grooves of the inductor. Under the influence of this force, the flow of electrically conductive particles is divided into two streams. As a result, the path traveled by the electrically conductive particle decreases, which improves the quality of the electrically conductive fraction.
