The invention relates to a technique for separating various ferromagnetic alloys according to chemical composition at various Curie points, such as scrap metal from the electronics industry.

The aim of the invention is to increase productivity and reduce energy intensity.

The drawing shows a thermomagnetic separator, a general view.

The thermomagnetic separator for separating various ferromagnetic alloys according to chemical composition depending on the Curie point contains a magnetic solenoid system 1, the loading hopper 2, located on three sides of the magnetic circuit, installed above the working heating chamber consisting of the inner wall 3 of non-magnetic material, the outer 4 and end 5 walls of ferromagnetic material, the heating element 6, which is wound on a coil on the outer surface of the inner wall 3 and connected to the power source (until en) AC. The magnetic system is located under the working chamber and is connected to the power supply. The rod is made of ferromagnetic material and consists of a middle part 7 of conical shape installed in the working chamber with the possibility of axial movement, an end cylindrical part (central rod) 8 that is spring-loaded through spring 9 relative to the hopper 2, and tip 10 of ferromagnetic material which through a non-magnetic ring insert 11 is connected to the middle part 7, installed above system 1 and has such a length that when current flows through the winding of the magnetic system, it interacts with the magnetic field retracted inside the solenoid.

The magnetic system is connected to a direct current source through the limit switch 12, interacting with the axial movement of the rod through the rigid connection 13 and through the distributor 14. with a thermocouple 15 so that the current is switched on only when the set temperature in the working chamber is reached, and - through a certain separator capacity and separation efficiency time interval. For submission to collections of chemical fractions separated by fractions, the magnetic system from the bottom is equipped with discharge trays 16 and 17.

Thermomagnetic separator works as follows.

A heating element 6 is turned on, the spiral winding of which creates a magnetic flux that flows outside the ferromagnetic wall and inside the working chamber along the ferromagnetic

rod, resulting in a circular air gap forms a magnetic gate. A separable mixture of ferromagnetic materials with different Curie points, for example Ni-cruia, Fe-alloys, is poured into bunker 2, from where it spills into the working chamber, where the first portions of the mixture hang in the magnetic gate, and the subsequent ones are wedged between the heater wall and lower conical surface of the rod. When the temperature in the working chamber is reached, the distributor 14 turns on the magnetic system 1, the magnetic field of which acts on the end part 8, and, overcoming the rigidity of the spring 9, lowers, causing the magnetic shutter in the working chamber and the mixture to break down due to its own weight. system 1 where ferromagnetic scrap particles

A thermomagnetic separator, including a hopper mounted above the working chamber, between the internal, external and end walls of which a heater with a power source is placed, a rod and a magnetic system with a power source located below the working chamber - that, in order to increase productivity and reduce energy consumption, the rod is made of ferromagnetic material and consists of end and middle parts of conical shape, while the middle part is installed inside the working chamber with zhnosti axially movable and spring-loaded end portion of the rod relative to the hopper, and

are attracted to the inner surface of the solenoid, and nonmagnetic at 400-25, by means of a hard connection from the wire, remain in the central part of the material and switch of the connection to spill into the outlet cable with the power source a magnetic current of the 16th system, which also When lowering the central rod, the specified switch is connected to a motor on the calculated length of the path, the power source, while separating with the help of a limit switch the endorser is equipped with a ferro-magnetic tip 12 1, of a filament material, which, as a result, the magnetic ring non-magnetic insertion field c disappears. solenoid and ferromagnetic connected to the middle part of the rod and the particles of the mixture under the action of self-placed above the magnetic system of the weight gained fall around the periphery on the sludge inner wall

the water tray 17, and the rod under the action of the spring 9 moves upwards and creates again an annular magnetic shutter, which stops the spilling of the mixture from the working chamber. However, in the calculated length of the upward movement of the rod through the valve 14 and the switch 12 again turns on
