SU1461508A1 - Magnetohydraulic separator - Google Patents

Abstract

The invention relates to magnetic enrichment and improves the efficiency of the process for separating liquid metal and slag. Separator includes magnetic core 1 with primary winding 2, ring crucible 3 with bottom 4 and inlet 5 and outlet 6 and 7 nozzles. The partition 8 is located inside the crucible. An i-shaped magnetic conductor 9 is installed around the crucible 3. The initial melt enters the crucible 3 through the inlet. When the primary winding 2 is turned on in the melt and the crucible, currents are induced. These currents induce a secondary magnetic field. Due to the magnetic core 9, the magnetic field is concentrated in the crucible. A quasiout desire for molten metal occurs. Slag, salts and other inclusions float to the surface and are removed through the nozzle 7. The partitions 8 do not allow the separated components of the mixture to mix. Pure metal flows through the pipe 6. 4 Il. sl with i4

Description

Phie.g

The invention relates to the magic enrichment and can be used for the purification of liquid metals from remittances.

The purpose of the invention is to increase the efficiency of the separation process.

FIG. 1 depicts a magnetohydroinamic separator, general view; in fig. 2 - the same, top view; for 10 games. 3 shows the node I in FIG. 2; in fig. FIG. 4 - section A-A, in FIG. 3

The magnetohydrodynamic separator contains a closed magnetic circuit 1 with a primary winding 2, an annular 15 crucible 3 with a bottom 4, which is a secondary winding, with an input 5 and output b and 7 nozzles, vertically mounted partitions 8 placed with a gap relative to 20 bottom 4 and upper parts of the crucible .3, and the encircling ring crucible 3 is a U-shaped additional magnetic conductor 9. The bottom 4 of the crucible 3 is made of a material with a high specific electrical conductivity, 1N efficiency, for example copper, the partitions 8 are made of an electrically conductive material hydrochloric .vypolnen pipe 6 from a material having low conductivity (ceramics etc.) 30 is provided with two diametrically arranged openings 10 and 11 and are rotatably mounted in a circle the vertical axis.

 The magnetohydrodynamic separation- jj torus works as follows.

The primary winding 2 V1 is plugged into the mains. At the same time, along the walls of the crucible 3 and its bottom 4 will flow — induced currents that heat up the gel 3. The heated crucible 3 through the inlet 5 enters the slag-metal melt, as a result of which the crucible 3 has a slag-metal melt melt (like on the secondary winding dd transformer) induced currents flow. The currents flowing azimuthally along the annular crucible 3 (along the slag-metal melt, the bottom and walls of the crucibles) induce their own magnetic field, closing along the U-shaped magnetic cores, penetrating the crucible 3 in the radial direction. The interaction of the azimuthal electric current with a radial magnetic field in the crucible 3 creates an axial electromagnetic force 1, directed vertically downwards. When this happens, the liquid metal is quasi-desire, and slags, air puffs, salts, and other inclusions that are not affected by electromagnetic forces (or act much weaker than the liquid metal) float to the surface of the liquid metal. Thus, the slag-metal flow in the crucible will gradually stratify into two noTOKat metal flowing below the partitions 8 and slag (salt) flowing: above the partitions 8, and in the sections between the partitions 8 the melt separates: in the case of electromagnetic forces, the metal particles move down, and non-metallic. Kie - up. The slag flows out of the crucible 3 through the drain toe (outlet) and the liquid metal through the outlet b.
