Изобретение относитс к обогатительной технике и может быть использовано во вторичной цветной металлургии дл разделени смеси металлов на фракции.The invention relates to a dressing technology and can be used in secondary non-ferrous metallurgy to separate a mixture of metals into fractions.

Известно устройство дл извлечени металлических частиц из формовочной земли, включающее наклонный лоток, проход щий через селеноид 1.A device is known for extracting metallic particles from the moldable earth, comprising an inclined chute passing through selenoid 1.

Недостатком данного устройства вл етс низка эффективность процесса разделени материалов.The disadvantage of this device is the low efficiency of the material separation process.

Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс электродинамический сепаратор, включающий магнитопровод в виде наклонио установленной пластины, соединенной с вибратором , обмотку возбзждени , питатель и приемники продуктов разделени 2.The closest to the proposed technical essence and the achieved result is an electrodynamic separator, which includes a magnetic circuit in the form of an inclined mounted plate connected to a vibrator, an excitation winding, a feeder and receivers of separation products 2.

Недостатком данного устройства вл етс низкое качество выделенных фракций.The disadvantage of this device is the low quality of the isolated fractions.

Цель изобретени - повышение качества выделенных фракций.The purpose of the invention is to improve the quality of the isolated fractions.

Указанна цель достигаетс тем, что в электродинамическом сепаратора, включающем магнитопровод в виде наклонно установленной пластины, соединенной с вибратором, обмотку . возбуждени , питатель и приемники продуктов разделени , пластина выполнена с расшир ющимис кверху пазами, размещенными вдоль направлени движени материала, а обмотка возбуждени расположена в нижней части пазов .This goal is achieved by the fact that in an electrodynamic separator, including the magnetic core in the form of an inclined plate, connected to the vibrator, there is a winding. excitation, feeder and receivers of separation products, the plate is made with upwardly extending grooves placed along the direction of movement of the material, and the excitation winding is located in the lower part of the slots.

Кроме того, обмотка возбз ждени может быть вьшрлнена в виде кольцевых индукторов In addition, the waiting winding may be provided in the form of circular inductors.

Электродинамический сепаратор включает магнитопровод 1, обмотку 2 возбуждени , питатель 3, загрузочную воронку 4, разгрузочные течки 5, пружинные опоры 6, вибратор 7, щар20 нирный стержень 8 и приемники 9 дл продуктов разделени .The electrodynamic separator includes a magnetic core 1, an excitation winding 2, a feeder 3, a feed funnel 4, discharge chutes 5, spring supports 6, a vibrator 7, a ball 8 and receivers 9 for separation products.

Claims

The magnetic core 1 is made of ferromagnet-; material in the form of plates with longitudinal parastyle slots 10, extending upward. The magnetic conductor 1 is set obliquely to the horizontal plane (preferably under the 5-30 ° fragile depending on the type of raw material) of the spring supports 6, is held in a predetermined position by means of the hinge rod 8 when the vibrator 7 is connected to the magnet by the wire 1 and is located under him. The excitation winding 2 consists of section 11. Each section 11 is made in the form of a flat rectangle laid with its long sides in the adjacent slots 10 of the magnetic conductor 1. The next section 11 of the winding is connected to the next adjacent pair of slots 10. Section I are connected in series. The feeder 3 is made, for example, in the form of a belt conveyor, located above the feed hopper 4 and iaepxoM of the magnetic pipe L of the hopper hopper 4 located below the power supply 3 and above the upper part of the magnetic pipe 1. The discharge chutes are inclined at an abrupt angle to the plane of the magnetic pipe 1 on different level x Leaks 5 are fastened to the end of the magnetic core. Spring support 6 connects with the magnetic core at its ends. The vibrator 7 is located under the magnetic core 1 and is connected to the latter in its middle part. Receivers 9 are installed under the respective chutes. The separator works as follows. The material to be separated is fed by the feeder 3 evenly into the feed funnel 4, from where it enters the surface of the magnetic circuit 1, oscillating under the action of the vibrator 7, and then into the slots 10 of the magnetic core 1. When the separated material is shaken, the friction forces between the particles weaken and the electrically conductive particles begin pick up under the action of electrodynamic forces, and the non-conductive particles remain in the lower layers. Thus, each fraction proceeds with the separation of the material along its chutes 5 enters the respective receivers 9. The technical and economic advantages of the proposed separator are as follows. Under the action of electrodynamic forces on the electrically conductive parts of the gravitational forces and vibrations, the initial material b, the electrical conductivity splits, and an empty njocTpaHCTBo is formed between the layers, thereby eliminating cm; stitching particles of different fractions when they are into heat 5. Thus, the wafer is expanding upwards grooves, placing along the movement of material, and placing the winding of the exciter; d) in the lower part of the grooves, improves the quality of the selected fractions. {Formula and | brete e and 1. Electrodynamics a cage separator comprising a magnetic core in the form of an inclined plate, connected to the vibrator, field winding, feeder and receivers of separation products, from; This is due to the fact that, for the purpose of improving the quality of the fractions, the plate is wavy with the slots widening upwards and located along the direction of movement of the material, and the excitation winding is split in the lower part of the grooves. 2. Separtor on and. 1, that is, that the excitation winding is designed in the form of ring inductors connected in series and located in adjacent grooves.
