Description
Technical field
The present invention relates to a kind of wet type circulation electromagnetic separation field, especially for selecting iron sand in the mixed liquor from river sand, ore pulp, nonmetal fine particle and iron tramp, rejecting a kind of Wet-type electromagnetic separator of iron tramp.
Background technology
Magnetic separation is the main beneficiation method of process iron ore.Metallic ore especially iron ore, after ore dressing, improves grade, reduces impurity content, is of value to smelting process.According to the practice of China, iron concentrate grade often improves 1%, and the capacity factor of a blast furnace can increase by 2% ~ 3%, and coke consumption amount can reduce by 1.5%, and consumption of limestone amount can reduce 2%.Many non-ferrous metals and the mineral of rare metals have different magnetic.When not obtaining final concentrate with gravity treatment and flotation, available magnetic separation carries out sorting in conjunction with additive method.
Magnetic separation, except effective grade that can improve metallic ore, can also be rejected the harmful iron tramp in nonmetal raw material, so magnetic separation is one of operation important in nonmetal ore-dressing.Along with raising and the needs of resource regeneration of human environment protection consciousness, the recovery that magnetic method is widely used in slag and old metal with to be separated and in the process such as sewage disposal.
Wet magnetic separator is a kind of magnetic separator that iron ore selects factory generally to use, and wherein, drum type brake magnetic separation owner will be made up of cylinder, magnetic roller, brush roll, magnetic system, cell body, running part 6 part.Operationally, driven by motor cylinder and magnetic roller and brush roll do gyration, and to make ore pulp under loose condition (of surface) under the influence of a magnetic field, magnetic ore particle in ore pulp is moved to pole orientation, and to be attracted on cylinder, non magnetic ore particle comes off from cylinder.Although magnetic ore particle can be separated by the magnetic separator of this kind of structure from ore pulp, but its structure, every part in 6 parts of composition all needs to be equipped with relevant auxiliary part, as the magnetic patch in cylinder need be contained on the base plate of yoke with stainless steel bolt, the axle head that yoke extends cylinder is also fixed with connecting lever, in order to adjust magnetic system drift angle, adjust suitable after can be fixing etc. with pull bar, so the complex structure of the magnetic separator of this kind of structure, cost of manufacture is higher.The wet magnetic separator of another kind of structure is vertical ring magnetic separator, this magnetic separator has a becket, its underpart is provided with magnetic pole, becket is made vertically to be rotated between the two poles of the earth, magnetic ore particle is made to be attached to becket surface, and turn to the more weak top of magnetic field intensity by becket, by water under high pressure, magnetic ore particle is punched in stock chest.This kind of magnetic separator separation index is relatively low, and structure also relative complex; Simultaneously because the ore pulp flowing velocity in vertical ring magnetic separator is relatively very fast, even if apply the magnetic field of intensity to it, its leakage selects rate also larger.
Traditional magnetic separation mode adopts continuous multi-stage concentration equipment to carry out magnetic separation usually, and floor space is large, long flow path, be not easy to management, and the utilization rate of raw material is subject to the restriction of magnetic separation hop count.A kind of iron ore dry powder magnetic separation technology announced as Chinese patent CN101954311B and equipment just have above shortcoming.
Summary of the invention
For overcoming above-mentioned defect, the invention provides a kind of Wet-type electromagnetic separator and magnetic selection method, can circulate magnetic separation, improves the utilization rate having the mixed liquor of ore pulp, nonmetal fine particle and iron tramp, the circulation conduit of mineral simply not easily blocks, and can a large amount of feed of Seal treatment; Solve traditional magnetic separation mode floor space large, long flow path, is not easy to the shortcomings such as management simultaneously.
Technical scheme of the present invention is achieved in that
A kind of Wet-type electromagnetic separator, comprise bearing, magnetic separation barrel is arranged on bearing by rotating shaft, the upper taper cone barrel that magnetic separation barrel is connected by bottom surface, lower taper cone barrel is formed, upper taper cone barrel, lower taper cone barrel top is respectively upper intake, lower intake, upper taper cone barrel, rotate respectively in lower taper cone barrel and be provided with rotating shaft, rotating shaft is fixedly installed and arranges electromagnet more, upper taper cone barrel, be provided with cover in lower taper cone barrel and be placed in upper sparge pipe outside rotating shaft, lower sparge pipe, upper sparge pipe, lower sparge pipe is distributed with hole for water spraying, upper sparge pipe, lower sparge pipe is externally connected with high-pressure water, water fender is separated with between upper taper cone barrel and lower taper cone barrel, meniscate slurry leakage hole is provided with between water fender four edges and magnetic separation barrel inwall, water fender includes upper partition, lower partition, four groups of linear electric motors are provided with in space between upper partition and lower partition, four groups of linear electric motors drive the water fender being connected with and matching with four slurry leakage holes respectively, described upper partition, lower partition upper berth is equipped with electromagnet.
Described upper partition, lower partition are respectively equipped with fountain head, lower fountain head, upper fountain head and lower fountain head are connected with high-pressure water.
Concentration equipment is electromagnet, the presence or absence of its magnetic can be controlled by control circuit, make it at absorption mineral of suitable time and released mineral, an electromagnet part is arranged on traverses on the rotating shaft of circular cone, a part is arranged on the two sides of water fender, under the driving of rotating shaft, the electromagnet on axle can sway, and has both stirred the probability that mortar further increases absorption mineral.
Flusher is several water jets that rotating shaft distributes, and connects water source, and control the folding of water jet by the control circuit in rotating shaft by the water pipe installed in rotating shaft.When electromagnet power-off and magnetic disappear (now rotating shaft is still in rotation), water jet starts bath, and rinsed well by the mineral be attached on electromagnet and rotating shaft, finally, open gape, mineral are discharged.EGR is connected with bearing by drive unit.Drive unit be one can 180 °, plane rotate whirligig.
Advantageous Effects of the present invention is as follows:
One-time feeding of the present invention repeatedly magnetic separation capable of circulation, improves the utilization rate having the mixed liquor of ore pulp, nonmetal fine particle and iron tramp.The present invention is completely closed, decreases the waste of raw material and the pollution of residue; And the present invention is owing to have employed the circulating system of double cone cylinder and drive unit formation, when forwarding diverse location under the driving of double cone cylinder at drive unit, coordinate the folding of Based Intelligent Control water fender, can realize mixed liquor replacing between two hollow cones, mixed liquor is capable of circulation is increased substantially the efficiency of magnetic separation and the utilization rate of mortar by magnetic separation.Magnetic selection method in the present invention, all complete in a device the repeatedly magnetic separation of raw material, floor space is little, and flow process is short, is convenient to management, and the utilization rate of raw material is not by the restriction of concentration equipment quantity.
