Abstract
The utility model discloses a choice structure that permanent magnetism and electromagnetism combined together, the magnetic field and the semi-ellipsoid body of bottom between the magnetic coil in the mobile iron ore pulp passes through the inside permanent magnet of blocker and the select other section of thick bamboo inner tube outside obtain the high-grade concentrate.
Description
Technical Field
The utility model relates to an iron ore refining equipment, especially a magnetic separation iron ore equipment.
Background
The selection structure of iron ore at present is that the selection section of thick bamboo inner tube outside is twined solenoid for the selection, and is more getting closer to barrel axis magnetic field like this and can be weaker, and the ore dressing ability descends. In addition, the bottom of the existing equipment is designed to be an inverted cone, and the sedimentation area is small.
Disclosure of Invention
The utility model provides a technical scheme that its technical problem adopted is:
1. a permanent magnet module (4) is arranged on the inner wall of a closed cavity of a material blocker (3) (the lower part of which is a sealed cavity) at the center of a cylinder body of the fine selection equipment (figure 1). The magnetic field distribution in the range of the ore pulp flow field is more uniform (the magnetic field intensity at the central part is compensated) by combining with an electromagnetic coil (5) at the outer side of the inner cylinder of the equipment grading cylinder.
The permanent magnet is in modular design, and the specific technical scheme is that the permanent magnet is a stainless steel cylindrical barrel with a thick upper part and a thin lower part (figure 2). The upper part of the cylinder body is provided with a flanging (8) at the inner side. The lower part of the cylinder body is thinner and is provided with an outward flange (10).
The structure is simple and reasonable, does not need additional connecting pieces, and is simple and convenient to place and take out.
2. The bottom of the fine selection equipment (figure 1) is changed into a semi-ellipsoid (7) design from an inverted cone design.
3. The upper part of the overflow device (2) is provided with an ultrasonic device (1) which calculates the pulp flow by measuring the pulp flow velocity.
The beneficial effects of the utility model are that, the magnetic field distribution that permanent magnet module (4) and equipment selected the other section of thick bamboo inner tube outside solenoid (5) combine to make the ore pulp flow field within range is more even (compensation center part magnetic field intensity), and the equipment steady operation in-process most ore pulp is from bottom to top flow the in-process because the dual function of magnetic field and gravity makes iron ore deposit gradually and collect the concentrate case in the ore outlet, improves the grade of iron ore. The upper flanging of the stainless steel cylindrical barrel of the permanent magnet module can not only strengthen the structure, but also support the weight of the modules accumulated on the upper part, and can be used as a handle for taking and placing operations. The lower flanging of the stainless steel cylindrical barrel not only leaves a space for adhering the permanent magnet (9), but also has the function of structure reinforcement, and simultaneously can prevent the permanent magnet from falling off under the condition that the metal adhesive is not firmly adhered due to various reasons. The ultrasonic device can monitor and collect the flow data of ore pulp in real time.
Drawings
The invention will be further described with reference to the accompanying drawings and examples.
FIG. 1 is a longitudinal section of a refining apparatus
FIG. 2 is a longitudinal section of a permanent magnet module
In the figure, 1, an ultrasonic device, 2, an overflow device, 3, a material blocking device, 4, a permanent magnet module, 5, an electromagnetic coil, 6, an outer cylinder, 7, a semi-ellipsoid, 8, an upper flanging of the permanent magnet module, 9, a permanent magnet and 10, a lower flanging of the permanent magnet module
Detailed Description
Iron ore pulp enters a magnetic field area between the material blocking device and the inner cylinder of the grading barrel from a discharge hole of the material blocking device (3), most of the pulp is discharged from an overflow device (2) at the upper part of the equipment due to the fact that a bottom ore outlet is smaller in a stable operation state, and the pulp gradually sinks in a flowing interval of the section under the double effects of a magnetic field and gravity and enters a concentrate box from a bottom inverted cone ore outlet, so that high-grade iron ore is obtained.
Claims (3)
1. A choice structure combining permanent magnetism and electromagnetism is characterized in that a material blocker (3) is arranged in a sorting cylinder (6), an electromagnetic coil (5) is arranged on the outer side of an inner cylinder of the sorting cylinder, and a permanent magnet module (4) is arranged on the inner side of the material blocker (3);
