Embodiment Construction

[0027] Depend on Figure 1-5 It can be seen that the magnetic trap device for purifying liquid metal at high temperature (usually >300° C.) according to the present invention includes: a permanent magnet 1 , a yoke 2 , a sorting space 3 and an armature 6 . Depend on figure 2 It can be seen that the permanent magnet 1 and the yoke 2 form a magnetic circuit with an air gap, and the sorting space 3 is located in the air gap; image 3 It can be seen that in the sorting space 3, the arched magnetic-gathering medium screen 4 with an arc length larger than a semicircle is staggered; Figure 4 It can be seen that what constitutes the magnetic-gathering medium screen 4 is magnetic-conductive stainless steel wool 7 and non-magnetic stainless steel wire 8, and then by figure 1 It can be seen that the magnetic field direction H 0 , liquid metal flow direction v 0 And magnetic stainless steel wool 7 three mutually perpendicular, can produce high magnetic field gradient on magnetic sta...

Abstract

The invention relates to a magnetic well device for purifying high-temperature liquid metal, which comprises a permanent magnet, a magnet yoke, separation space and an armature, wherein an arch magnetism gathering medium silk screen with the arc length larger than a semicircle is arranged in the separation space in a staggered way, and is formed by magnetic stainless steel furs and non-magnetic stainless steel wires; for a magnetic field direction and a liquid metal flowing direction, the magnetic stainless steel furs are vertical to the two directions, and the non-magnetic stainless steel wires are in parallel to the magnetic field direction and vertical to the liquid metal flowing direction; and the armature, the permanent magnet and the magnet yoke form a closed magnetic circuit so as to be convenient to postprocess. The magnetic well device for purifying the high-temperature liquid metal has a simple structure and reasonable arrangement, is convenient to manufacture, is simple and easy to postprocess, and is an energy-saving high-gradient magnetic force purification device applied to the high-temperature liquid metal.

Description

technical field [0001] The invention relates to a magnetic trap device in high-temperature liquid metal purification technology, which belongs to an energy-saving high-gradient magnetic purification device. Background technique [0002] Magnetic separation was first applied in the field of mineral processing. It is a simple and effective material processing method to improve the purity of ore through magnetic separation by using the different magnetic properties of minerals. Traditional magnetic separation devices can only be used for substances with strong magnetic properties. The developed high-gradient magnetic separation has been able to separate particles with weak magnetic properties, and has been applied in new fields of magnetic separation such as wastewater treatment and biomedicine. [0003] In principle, the magnetic trap is the same as the magnetic separation equipment, but the objects and media to be processed are different. The magnetic trap can effectively ca...
