Abstract

The utility model discloses a drum type magnetic separating device used for mining. A magnetic body is arranged on the outer side of a rolling drum in a stationary state, a charging conduit at the middle part of which a screw feeder is arranged at the inner part of the rolling drum, and the rolling drum has an inclination angle with the horizontal plane. The utility model has the advantages of effective utilization of the magnetic energy and high separating quality and efficiency.

Description

Tubular type magnetic sorting device

The utility model relates to a kind of concentration equipment that is applied to mining industry.

Comprise cylinder 1, magnet 2 in a kind of outer cartridge type concentration equipment (seeing accompanying drawing 1) that uses at present, the magnet fixed in position is in the inside of cylinder and near its inwall, cylinder rotates, material enters from the inlet 4 in material road 3, then magnetic material is adsorbed on the outer wall of cylinder under the effect of magnets magnetic fields, discharge from exporting 6 at last, and non-magnetic material is discharged by gravity from the outlet 5 of bottom.There is following weak point in this concentration equipment: 1, the magnetic energy utilization rate is low, owing to adopt outer cartridge type structure, the suction that magnet offers magnetic material must overcome the gravity of material, in addition, the bed of material has certain thickness and work sideshake, therefore must possess the outer surface that enough magnetic field intensities could be adsorbed onto magnetic material cylinder; 2, owing to require certain workload, delivery rate has certain requirement, and then material is short in working region, the magnetic field holdup time, and the material levels not have string moving, so the sorting quality of this device and efficient are all relatively poor.

The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art part, provides a kind of and can more effectively utilize all high cartridge type concentration equipment of magnetic energy, sorting quality and efficient.

The purpose of this utility model is achieved in that a kind of cartridge type concentration equipment, comprise cylinder, magnet, the outside that said magnet is placed in cylinder is stationary state, and said cylinder inside is provided with a magnetic material discharger, and said cylinder and horizontal plane have an inclination angle.

Below in conjunction with embodiment (accompanying drawing) the utility model is further described.

Fig. 1 is a kind of outer cartridge type concentration equipment structure principle chart of the prior art;

Fig. 2 is the front section view (omitting other running part among the figure) of the utility model cartridge type concentration equipment;

Fig. 3 is the side sectional view of the utility model cartridge type concentration equipment.

This cartridge type concentration equipment comprises cylinder 7, magnet 12, the outside that magnet is placed in cylinder is stationary state, is positioned as close to the outer wall of cylinder, can effectively utilize magnetic energy like this, the inside of cylinder is provided with a magnetic material discharger, and cylinder and horizontal plane have an inclination angle [theta]; In the present embodiment, the magnetic material discharger comprises a low water 8 and a screw feeder 11, and screw feeder is arranged on the middle part of charging conduit, and the magnetic material discharger also can be linked by a charging conduit and a vibrating device (not shown) and constitute certainly; Charging conduit is V-shaped, in addition for increasing the ability that sorts in magnetic field, is welded with horizontal bar plate 10 and the line reinforcing bar 17 of arranging in the shape of a spiral at drum inner surface; Horizontal bar plate 1 plays the scraper effect, when the horizontal bar plate enters into no magnetic region with cylinder, the magnetic field gradient that will make horizontal bar plate place that suddenly disappears in magnetic field increases, magnetic material just may be detained herein, the effect of horizontal bar plate promptly is these magnetic materials are scraped and takes away, reinforcing bar 17 magnetizes under magnetic field induction and promptly is equivalent to a fritter magnetic patch, can improve separating effect like this; In this concentration equipment when work, is under the drive of drive disk assembly, cylinder rotates, material enters with the rotation of cylinder from the inlet 14 of cylinder and does not stop to stir, and under the effect of gravity and reinforcing bar 17, roll downwards gradually, in such process, material and drum inner surface touch opportunity are more, and magnetic material constantly is adsorbed in inner wall of rotary drum and rises to no magnetic region and fall into charging conduit by gravity, some are still adhered to magnetic material on the barrel, its brush is fallen into charging conduit by brush board 9; At last at screw feeder or under the effect of vibrating device vibration, the magnetic material in the charging conduit is discharged from, non-magnetic material then is discharged from from the outlet 15 of cylinder; In addition, the inclination angle [theta] of cylinder and horizontal plane can be adjusted by a governor motion (not drawing among the figure), can satisfy the requirement of different operating amount like this.

The utility model compared with prior art has the following advantages:

1, the gravity that magnetic energy utilization rate height, the magnetic force that magnet provides must not overcome material can promote magnetic material;

2, material constantly turns over stream in cylinder, and material is long in the magnetic workspace holdup time, and material constantly contacts with inner wall of rotary drum, and sorting quality and effect are higher like this.
