Description

Adjustable multi-frequency electromagnetic ultrasonic mineral separation device
Technical Field
The invention belongs to the technical field of metallurgy, and particularly relates to an adjustable multi-frequency electromagnetic ultrasonic mineral separation device which is simple in process, high in yield, low in energy consumption, small in pollution and low in equipment investment.
Background
The magnetic minerals are usually beneficiated by flotation, magnetic separation, gravity and other techniques. Wherein, the magnetic separation is a mineral separation method for separating different minerals from each other by utilizing the magnetic difference between the minerals in a non-uniform magnetic field.
At present, the permanent magnet drum type magnetic separator is one of the most widely applied magnetic separation equipment due to the advantages of simple structure, convenient and reliable use, large treatment capacity and the like. However, because the magnetic system of the permanent magnet cylinder magnetic separator is fixed, the number of alternating magnetic poles is limited by the structural space and cannot be greatly increased, so that the selected magnetic minerals quickly form compact magnetic clusters near the surface of the cylinder of the magnetic system, gangue wrapped in the minerals is difficult to remove, the quality of concentrate is reduced, and the production requirement of the concentration operation is difficult to meet. For this reason, in the prior art, aiming at the defects of the permanent magnet drum type magnetic separator, there is a possibility that the number of magnetic poles is increased or the magnetic field gradient is enhanced by changing the structure of the drum or adding the structure of the magnetic addition medium in the drum, so as to increase the opportunity of eliminating the non-magnetic particles wrapped in the magnetic clusters; however, due to the limitation of the structural space of the cylinder, the number of the magnetic poles which can be increased is limited, the improvement effect is not obvious, and the magnetic separator is complex in structure and is worn seriously. In addition, a stirring structure or pressure water flow is added in the permanent magnet drum type magnetic separator, and the magnetic clusters are destroyed by using stirring force or water flow impact effect so as to improve the separation precision of the magnetic separator; however, because the magnetic force between the magnetic minerals is large, the formed magnetic clusters are compact, and the magnetic clusters are difficult to break due to stirring or water flow impact force, the actual concentrate separation effect is not obvious, so that the concentrate separation in the minerals is insufficient, the mineral yield is low, the energy consumption for mineral separation is high due to the increase of the stirring structure, and the water consumption and the sewage treatment pressure are increased due to the water flow impact.
In the prior art, ultrasonic waves are introduced into a permanent magnet drum type magnetic separator, an ultrasonic dispersing device is added at the lower part of a mineral feeding port of a horizontal permanent magnet drum type magnetic separator, and flushing water pipes are respectively arranged at the mineral feeding port and a concentrate port, so that magnetic agglomeration is jointly destroyed by utilizing the actions of ultrasonic dispersing force, gravity, water flow impact force and the like, and the grade and the beneficiation efficiency of concentrate are improved. However, as the magnetic system adopts a permanent magnet structure, the magnetic field intensity and gradient are difficult to be adjusted in a targeted manner according to the magnetic size and the wrapping form of minerals, so that the application area of mineral dressing is narrow, a large amount of flushing water also causes larger water consumption and larger post-treatment difficulty, and the horizontal structure also causes larger occupied area. Therefore, in the prior art, a stirring mechanism is arranged in the vertical hollow cylindrical ore dressing equipment main body, a water spraying pipe is transversely arranged at the lower part of the vertical hollow cylindrical ore dressing equipment main body, a disc-shaped ultrasonic generator is arranged at the bottom of the ore dressing equipment main body, and an annular pulse electromagnet is arranged around the upper part of the outer wall of the ore dressing equipment main body, and an annular electromagnet is arranged in the middle of the outer wall of the ore dressing equipment main body. The stirring mechanism enables ore entering the main body of the ore dressing device to move downwards obliquely rapidly, concentrate is enabled to sink continuously under intermittent injection of the water spray pipe, the ore with general or extremely low content sinks slowly or runs upwards to complete primary separation, then the sinking ore enables magnetic ore and non-magnetic substances to separate rapidly under intermittent electromagnetic action of the annular pulse electromagnet, the annular electromagnet can capture the magnetic ore in the ore continuously, so that the magnetic ore and the non-magnetic substances are separated more fully, then the ore sinking into the bottom is redistributed under ultrasonic vibration of the ultrasonic generator, concentrate is enabled to sink in the bottommost layer of the main body of the ore dressing device intensively, the concentrate is pumped out by the ore pump conveniently to improve the ore dressing efficiency and the concentrate grade, and ore pulp after ore dressing flows out from the overflow pipe at the top. Compared with the horizontal structure, the vertical structure has small occupied area, but because the ultrasonic generator is arranged at the bottom, the ultrasonic generator only plays a role of redistributing the ore at the bottom, and the grade of ore concentrate can be improved, but the middle part and the upper part of ore pulp in a main body of ore dressing equipment are difficult to effectively destroy magnetic clusters by means of stirring and water flow impact, so that non-magnetic particles wrapped in the magnetic clusters are sunk along with the ore concentrate under the action of stronger magnetic force to reduce the grade of the ore concentrate, and the magnetic clusters wrapped with the non-magnetic particles are overflowed upwards under the action of weaker magnetic force to reduce the yield. Therefore, research on mineral separation equipment with simple process, high yield, low energy consumption, little pollution and low equipment investment is a technical problem to be solved urgently by those skilled in the art.
