Abstract
The utility model relates to a magnetic system distributing structure of a counter flow wet magnetic separator, which comprises a plurality of magnetic poles arranged in an arc-shaped manner, wherein the intervals between the 5 magnetic poles at the mine tailing side are different, and the gaps between every two adjacent magnetic poles increase gradually from left to right along the mine tailing side. The improved magnetic system structure requires only 13 magnetic poles less than 2 magnetic poles in comparison with the traditional structure, therefore the structure is optimized and more compact, and the production cost is saved; as the gaps between the magnetic poles at the mine tailing side are widen gradually, the magnetic field of the whole magnetic system has a gradient change instead of being uniformly and symmetrically distributed in the circumferential direction of a magnetic cylinder, weakening from the concentrate weir to the tailing weir gradually, and the magnetic field with the gradient change is more favorable for the recovery of magnetic media.
Description
Technical field
The utility model relates to a kind of adverse current type wet magnetic separator, specifically the magnetic pole distributed architecture of adverse current type wet magnetic separator.
Background technology
The adverse current type wet magnetic separator is to be used for reclaiming ferromagnetism dense media (tri-iron tetroxide or ferrosilicon) in dense media sorting operation production technology, is applicable to the higher and very low occasion of magnetic mineral loss requirement of magnetic mineral concentration.The ore pulp that is mixed with magnetic and non-magnetic media is fed magnetic separator, and magnetic separator can separate them, makes magnetic medium obtain reclaiming and concentrating.
The feed-type of such magnetic separator is that the flow direction of the direction of rotation of magnetic cylinder and ore pulp is opposite.Magnetic mineral is separated from ore pulp by the magnetic attraction of magnetic cylinder and is driven from concentrate outlet discharge by the magnetic cylinder that rotates.And mine tailing must just can be discharged from through behind all magnetic poles, and magnetic-particle just has more opportunity by the magnetic field sucking-off like this, so the magnetic mineral rate of recovery is very high.Relatively low flow velocity in overflow area can make the recovery of thin magnetic-particle become easy.
In traditional manufacturing process, the structural arrangement of magnetic pole as shown in Figure 1 in the magnetic system: closely arrange between the magnetic pole, amount to 15 magnetic poles, magnetic field along the circumferential direction is symmetrically distributed.This tight, equally distributed field structure needs the number of magnetic poles of utilization many on the one hand, also is unfavorable for the recovery of magnetic medium on the other hand.
The utility model content
It is distributed architecture that the purpose of this utility model provides a kind of adverse current type wet magnetic separator magnetic, and it is many and be unfavorable for the problem of magnetic medium recovery to solve number of magnetic poles that tight, equally distributed field structure commonly used need utilize.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of adverse current type wet magnetic separator magnetic is distributed architecture, comprises being some magnetic poles that circular arc distributes, and no longer closely arrange between 5 magnetic poles of mine tailing side, but have certain clearance, and the gap between adjacent two magnetic poles from left to right increases gradually along the mine tailing side.
Magnetic architecture after the improvement only need be compared few 2 magnetic poles of having used with traditional structure with 13 magnetic poles, has structurally obtained optimization, makes structure compact more, has saved production cost;
Owing to draw back the gap gradually between the mine tailing side magnetic pole, the magnetic field that whole magnetic is is no longer to distributing symmetrically along the magnetic cylinder circumferencial direction like that originally, but present graded, and to weaken successively to the mine tailing weir from the concentrate weir, this magnetic field that is the ladder variation more helps the recovery of magnetic medium.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is that the wet magnetic separator magnetic of using always is the external structure of distributed architecture
Fig. 2 is that the described adverse current type wet magnetic separator of the utility model embodiment magnetic is the structure chart of distributed architecture
The specific embodiment
As shown in Figure 2, wet magnetic separator magnetic described in the utility model is distributed architecture, comprises being some magnetic poles that circular arc distributes, and the spacing between 5 magnetic poles of mine tailing side is different, and the gap between adjacent two magnetic poles from left to right increases gradually along the mine tailing side.
Magnetic architecture after the improvement only need be compared few 2 magnetic poles of having used with traditional structure with 13 magnetic poles, has structurally obtained optimization, makes structure compact more, has saved production cost;
Owing to draw back the gap gradually between the mine tailing side magnetic pole, the magnetic field that whole magnetic is is no longer to distributing symmetrically along the magnetic cylinder circumferencial direction like that originally, but present graded, and to weaken successively to the mine tailing weir from the concentrate weir, this magnetic field that is the ladder variation more helps the recovery of magnetic medium.
