Technical Field
The invention relates to the technical field of superconducting magnetic separation devices, in particular to a double-station sorting device.
Background
China is a large country for mineral production and consumption, and mineral resources such as kaolin, quartz, bauxite, polycrystalline silicon, rare earth and the like have great demands. In recent years, the rapid development of the industries such as building material ceramics, optical glass, photovoltaics, optical communication, semiconductors and the like in China is continuously promoted to the upstream of an industrial chain with higher added value, the living standard of substances is continuously improved, the requirement on raw materials is higher and higher, and the requirement on high-purity raw materials is more and more urgent. However, due to the limitation of separation technology and process equipment, high-purity raw materials and single oxides of rare minerals still have strong dependence on import.
The magnetic separation device is mainly suitable for separating substances with magnetic differences, is one of important devices for separating raw materials, and is mainly divided into a permanent magnet type, an electromagnetic type and a superconducting magnetic type; the superconducting magnetic separation device is equipment which utilizes a superconducting state conductive coil to generate a strong magnetic field and separates ore particles in ore pulp according to the magnetic difference of different ore particles; compared with permanent magnet type and electromagnetic type magnetic separation modes, the magnetic field intensity provided by the superconducting magnetic separation mode is 2-3 times and 3-8 times of the maximum magnetic field intensity provided by the permanent magnet type and the electromagnetic type, the capture rate of magnetic particles in the superconducting magnetic separation mode is far higher than that in the traditional mode, and the superconducting magnetic separation mode is an advanced device in the mineral separation industry at present.
The existing superconducting magnetic separation device is a double-drum superconducting magnetic separation device which is a magnetic separation processing device mainly facing kaolin. The kaolin has the physical properties of fine granularity (generally-250 meshes) and relatively high viscosity, and is easily prepared into suspension ore pulp with the concentration of less than 18 percent after a certain proportion of dispersing agent is added, and then the wet magnetic separation treatment can be carried out by using a double-cylinder superconducting magnetic separation device. However, the double-drum superconducting magnetic separator has very limited processing capacity for ore pulp with coarse particle size (> -150 meshes) and large concentration (concentration > 30%), and is not suitable for materials with coarse particle size and small viscosity and materials which are inconvenient to prepare into suspension.
In the existing superconducting magnetic separation device, prepared ore pulp usually passes through a magnetic conductive medium in a horizontal flowing mode, the ore pulp is inevitably influenced by gravity, when the ore pulp passes through at a lower flow rate, the ore pulp is influenced by gravity and cannot be fully contacted with the magnetic conductive medium, the magnetic separation effect is influenced, and the superconducting magnetic separation device is particularly suitable for high-concentration ore pulp. And when a magnetic separation process is finished, the internal channel of the separation cavity structure and the porous space of the magnetic conduction medium can both retain ore pulp, and the retained ore pulp can only be replaced by the entering water flow, so that the concentration of the ore pulp is inevitably diluted. Because the magnetic media are all nested inside the sealed sorting cavity structure, changing the magnetic media is complicated and time-consuming (at least 4 hours), and requires professional operators to operate.
In conclusion, the application range of the superconducting magnetic separation device to wet magnetic separation of more minerals is expanded, gravity factors are reasonably avoided and even utilized, and the technical problem to be solved urgently when the superconducting magnetic separation device is popularized and applied is solved.
