AND

The present invention relates to a permanent magnet separator and to the realization of an optimal shape of a magnetic circuit.

For permanent magnets manufactured so far, the dimensions are limited by the manufacturer's production possibilities. Larger magnetic blocks are therefore made by assembling smaller elements before / ιΐΗΐιρκ! I n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n t i n i n i n t i n i n i n i n i n i n i n i n i n i n i t i n t systems, especially in the case of magnetic separators, are formed by assembling already magnetized blocks Pre-cast screw bolts are usually used to attach the magnetic blocks. Structurally, the blocks can be attached to the steel yoke in only one layer, non-magnetic tools should be used in the work, and the steel yoke must be adapted to hold the magnetic blocks with screw bolts.

The disadvantage of the present invention is to eliminate the separating permanent magnet according to the invention, consisting of a special yoke and permanent magnet blocks, which consists in the fact that the permanent magnet blocks are housed in a skeleton of non-magnetic material treated on a steel yoke. magnets.

The advantage of the separating permanent magnet according to the invention is the possibility of arbitrary assembly of magnetic blocks and easy and safe handling of the magnetized blocks during their assembly. It is also an advantage that the skeleton allows the magnetic blocks to be held in multiple layers, thus creating an optimum magnetic circuit, while the course of the magnetic fields is not affected by their attachment. Furthermore, the advantage is that the magnet also allows a relatively easy change of the assembly of the magnetic blocks even during transit use, as well as the handling of oriented magnetized anisotropic magnets, whose mutual force action is even more pronounced.

The separating permanent magnets according to the invention are shown by way of example in the accompanying drawing, in which Fig. 1 is a partial cross-sectional view of the working poles and Fig. 2 is a side view.

The separating permanent magnet in the exemplary embodiment according to the invention is designed as a two-pole. Two skeletons 2 are mounted on the steel yoke X, ⁱⁿ whose sections 4 the magnetic blocks 2 are inserted. The skeleton 6 is made of a thin non-magnetic material. The individual magnetic blocks 2 are only inserted in the sections 4 of the skeleton 4, if necessary their position can be secured mechanically or by means of investment. The working surface to which the ferromagnetic objects are attached is formed by a cover sheet 4 of non-magnetic material. In addition to separating permanent magnets, the invention can also be used with load, holding and the like permanent magnets.
