A continuous moving magnetic pole vibrating bed high gradient permanent magnet magnetic separator

Abstract

The invention discloses a high-gradient permanent magnetic separator of a continuous dynamic magnetic pole vibrating bed. The high-gradient permanent magnetic separator comprises a first drive mechanism, a differential mechanism, a bed body, a transport mechanism and a second drive mechanism, wherein the first drive mechanism is used for driving the bed body to carry out asymmetric reciprocating motion in a horizontal direction; the differential mechanism is matched with the first drive mechanism, so that the bed body generates differential motion in asymmetric reciprocating motion; a permanent magnet layer is laid on the bed surface of the bed body; the upper surface of the permanent magnet layer is paved with a screening layer; the screening layer is formed by arranging wedge blocks which are made from ferrite permanent magnet magnetic steel, and a groove is formed in a joint of every two adjacent wedge blocks; the transport mechanism comprises a circulating belt; the bearing surface of the circulating belt is paved with a soft iron layer which consists of a plurality of soft iron sheets; the upper surface of the soft iron layer is paved with a steel mesh; and steel wool is arranged at each node of the steel mesh. According to the high-gradient permanent magnetic separator, the grooves and the wool are matched with each other, thereby realizing separation for magnetic substances with different magnetisms.

Description

technical field [0001] The invention relates to the technical field of magnetic separation, in particular to a continuous moving magnetic pole vibrating bed high-gradient permanent magnetic magnetic separator. Background technique [0002] Using the difference in magnetic properties of mineral particles, sorting in a magnetic field is a commonly used method for magnetic material sorting. Wet magnetic separator needs water as the working medium, which cannot be used in water-deficient areas, and may cause environmental pollution, so it is not worth promoting. Therefore, dry magnetic separation has developed rapidly in recent years. Traditional dry magnetic separators rely on the direct attraction of magnetic fields to capture magnetic mineral particles, but because the magnetic field lines in the magnetic field used to capture magnetic mineral particles in traditional dry magnetic separators are uniformly arranged, it is impossible to capture magnetic mineral particles with d...

Wet magnetic separator needs water as the working medium, which cannot be used in water-deficient areas, and may cause environmental pollution, so it is not worth promoting. Therefore, dry magnetic separation has developed rapidly in recent years.

Traditional dry magnetic separators rely on the direct attraction of magnetic fields to capture magnetic mineral particles, but because the magnetic field lines in the magnetic field used to capture magnetic mineral particles in traditional dry magnetic separators are uniformly arranged, it is impossible to capture magnetic mineral particles with different magnetic properties. sorting by magnetism
