Problems solved by technology

Especially at higher velocities this has the effect that a substantial part of the suspension flowing through the reactor is not drawn towards the inner wall of the reactor and leaves the reactor again without the ferromagnetic particles being separated out
For this reason, the separation rate is unsatisfactory at higher flow velocities in conventional devices

Embodiment Construction

[0023] in figure 2 The device 1 shown in FIG. 1 includes a tubular reactor 2 having a plurality of suction lines 3. The reactor 2 has a plurality of suction pipes 3 arranged one after another along the flow direction, and every two suction pipes 3 are opposite to each other.

[0024] Each suction line 3 is surrounded by a permanent magnet 4 formed in an annular shape. Each permanent magnet 4 is surrounded by a coil winding 5, by which the magnetic field generated by the permanent magnet 4 can be enhanced or weakened. The coil winding 5 is connected to a control device not shown.

[0025] Each suction line 3 can be closed or opened by means of a shut-off valve 6. Different suction pipes 3 merge into the suction pipe 7, in which there are pumps that generate negative pressure.

[0026] A plunger body 9 is arranged in the center of the interior of the reactor 2. In the illustrated embodiment, the plunger body 9 is configured as a tube. In other embodiments, the plunger body may als...

Abstract

The invention relates to a device for separating ferromagnetic particles from a suspension. Said device comprises a tubular reactor having at least one magnet, a suspension being able to flow through the reactor. A displacer (9) is arranged inside the reactor (2).

Description

Technical field [0001] The invention relates to a device for separating ferromagnetic particles from a suspension. The device has a tubular reactor capable of being passed through by the suspension, and the reactor has at least one magnet. Background technique [0002] In order to extract the ferromagnetic components contained in the ore, the ore is ground into powder and the resulting powder is mixed with water. The suspension is placed in a magnetic field generated by one or more magnets to attract ferromagnetic particles, thereby separating the ferromagnetic particles from the suspension. [0003] DE 27 11 16 A discloses a device for separating ferromagnetic particles from a suspension, for which a roller made of iron rods is used. The iron rods are alternately magnetized during the rotation of the drum, so that ferromagnetic particles are attached to the iron rods, while other components of the suspension fall between the iron rods. [0004] In DE 26 51 137 A1 a device for sepa...
