Abstract
The invention provides an improved direct current magnetic separator, comprising a feeding device, a magnetic separating drum and a drive mechanism thereof, which are installed on a stand, a magnetic system installed in the magnetic separating drum and a separating and discharging bunker arranged at the lower part of the magnetic separating drum. The direct current magnetic separator is characterized in that the feeding device is installed at the upper part of the magnetic separating drum; the magnetic system is composed of separated magnets installed at one side of the magnetic separating drum, and the wrap angle is 160, 180, 200 or 220 DEG. As the invention changes the feeding manner of ore slurry and the installation manner of the magnetic system of the magnetic separating drum, and the magnets are distributed in the magnetic system in separated manner through alternately changing the magnetic field direction, and then the grading precision of the magnetic ore slurry is greatly improved; meanwhile, the direct current upper port feeding manner and the average distribution of the feeding ports in the axial direction greatly improve the efficiency of the magnetic separating drum; the magnetic ore is smoothly discharged and the performance of processing the ore slurry reaches 80-280 t/h, therefore, the working efficiency is greatly improved, the structure is simple and the use is convenient, and the application prospect is broad.
Description
Technical field
The present invention relates to a kind of improved DC magnetic separator, belong to the mining machinery technical field.
Background technology
The working method of existing wet separator be ore pulp through side-fed, giving under the flow action of ore deposit sparge pipe, ore particle is the mining area of giving that loose condition (of surface) enters cell body, the magnetic ore particle is attracted on the cylinder.In order to improve the magnetic separation precision, be that the cornerite and the increase time of staying of ore pulp on magnetic separation roller are to make an issue of often increasing magnetic, bottom as existing magnetic separation casing is a circular arc, on at the bottom of the case, arc buffer board formation arcs of recesses dashpot is set, to slow down the admission velocity of recirculation water, flow action by the adverse current sparge pipe makes ore pulp be ejected into magnetic field, and production efficiency is by the flow action decision of adverse current sparge pipe, if the big magnetic separation roller that just easily stops up of inlet amount.Along with the continual renovation of preparation equipment, production capacity improves constantly, and existing magnetic separator can not satisfy supporting needs, and for this reason, designing a kind of magnetic separator that does not reduce the magnetic separation precision of raising the efficiency is the task of top priority.
Summary of the invention
Purpose of the present invention is exactly at the above-mentioned problems in the prior art, and the magnetic separation roller that provides a kind of Distribution of Magnetic Field to show unique characteristics is to shorten the sorting distance, to improve the DC magnetic separator that sorts precision and magnetic separation roller efficient.
Technical scheme of the present invention is achieved in that this improved DC magnetic separator, it comprises the feed arrangement, magnetic separation roller and the driving mechanism thereof that are arranged on the frame, be installed in the concentrate discharge groove that magnetic system in the magnetic separation roller and magnetic separation roller below are provided with, it is characterized in that: feed arrangement is arranged on magnetic separation roller top, described magnetic is by the interval that is arranged at magnetic separation roller one side magnet to be set to constitute, and cornerite is at 160 °, 180 °, 200 ° or 220 °.
Described improved DC magnetic separator is characterized in that: described magnetic is preferred 180 ° of cornerite
Described improved DC magnetic separator is spaced apart 5-8mm between described magnetic separation roller and the magnet.
Improved DC magnetic separator is characterized in that: interval 8-10cm or 10-15cm between the magnet of described magnetic separation roller.
Described improved DC magnetic separator, the direction of rotation of described magnetic separation roller is identical with feedstock direction.
Described improved DC magnetic separator, the below of described magnetic separation roller is provided with the discharging sparge pipe.
The improved DC magnetic separator of the present invention is a set-up mode owing to changed the magnetic of ore pulp feeding manner and magnetic separation roller, adopts the compartment distribution of magnets in magnetic system, makes the magnetic mineral slurry sort precision and improves greatly; Single flow charging suitable for reading and equally distributed vertically mode have significantly improved magnetic separation roller efficient simultaneously, drum rotation speed is bigger, magnetic mineral is discharged smooth and easy, handle the ore pulp ability and reach 80-280t/h, the mineral aggregate particle size range of magnetic separation of the present invention is bigger, and the 1-10mm mineral aggregate all can carry out magnetic separation, but Wet-dry, simple in structure easy to use, application prospect is very wide.
Description of drawings
Fig. 1 is a structural representation of the present invention
Among the figure: 1, feed arrangement 2, magnetic separation roller 3, magnet 4, guard shield 5, drive unit 6, frame 7, mine tailing export 8, unload ore deposit sparge pipe 9, concentrate discharge groove
The specific embodiment
Below the structural representation and the course of work of improved DC magnetic separator be example, embodiments of the present invention are described:
The present invention includes the drive unit (motor) 5 that is provided with on frame 6, the frame and drive magnetic separation roller 2 rotations, the magnetic system and the magnetic that are installed in the magnetic separation roller are that adjusting device, ore pulp are flowed directly into by the feed arrangement 1 that is arranged on magnetic separation roller top, ore pulp trend all the time with gravity in the same way, so called after single flow; Innovative point of the present invention is: magnet 3 is set in the described magnetic separation roller at interval forms magnetic system, between the magnet apart from 5-8cm, or 8-10cm or 10-15cm, the cornerite of magnetic system between 160-220 °, can preferred 160 °, 180 ° during practical application or 200 °, 220 ° magnetic separation roller bottoms be provided with and unload ore deposit sparge pipe 8 and concentrate hopper 9.
Magnetic separation roller is a revolving body during work, and it is non-revolved body that magnetic system is installed in the interior workspace of magnetic separation roller one side, and magnetic is 160 °-220 ° of cornerites.Big in theory cornerite magnetic is the working region that has prolonged absorption magnetic thing on cylindrical shell, help to strengthen and sort precision, but reduce the operating efficiency of magnetic separator easily, the present invention has improved behind the magnet set-up mode under the situation that inlet amount increases, the magnetic separation precision does not reduce, may be that magnetic circuit expansion makes magnetic efficiency improve, under gravity and centrifugal force acting in conjunction, by the change generation Magnetic Isolation of movement locus; Stop magnetic mineral and pile up the equipment performance reduction that causes.It is smooth and easy that magnetic mineral is discharged, handle the ore pulp ability and reach 80-280t/h, but the present invention can with the supporting Wet-dry of high-power ore pulp grinder, can reduce and shut down the adjustment time, energy-conservation, high-quality, is efficiently overhauled and convenient transportation.
Listed examples of the present invention is intended to further illustrate the combination and the application mode of this improved DC magnetic separator, and scope of the present invention is not constituted any restriction.
