Description

Technical Field

[0001] The utility model belongs to the technical field of wet permanent magnet machines, and in particular relates to a wet permanent magnet machine ore feeding device with a filter screen. Background Art

[0002] Wet drum magnetic separator is mainly composed of feed box, permanent magnet drum, etc. ( Figure 1 ). It is made of non-magnetic material - stainless steel plate rolled and welded, and the motor drives the reducer to rotate; the magnetic poles of the magnetic system are arranged alternately along the rotation direction of the cylinder, and are fixed during operation. Its working principle is: the ore slurry is fed into the feeding box through a uniform distribution device, and under the action of the feeding water flow, the ore particles enter the feeding area at the bottom of the box in a loose state to complete the ore dressing process. In the field production of the magnetic separator of the prior art, since the permanent magnetic separator is fed by a feeding pipe in the feeder, the ore feeding is uneven, which will cause the processing capacity in the middle of the magnetic drum to be too large, and there will inevitably be debris in the ore slurry transported by the pipeline, which is very easy to block the bottom box of the wet magnetic separator. At the same time, due to the feeding method of the magnetic separator, the processing capacity in the middle position is large, the processing capacity on both sides is small, and the ore carrying in the middle is serious, which affects the long-term working performance of the magnetic separator.

[0003] In view of the above factors, a wet permanent magnet feeding device with a filter is specially designed. The slurry can be better distributed on the magnetic drum, avoiding large processing volume in the middle, small processing volume on both sides, and serious ore carrying in the middle. It improves the yield of the magnetic separator and effectively avoids bottom box blockage. Utility Model Content
