Problems solved by technology
Most of the existing mineral refining furnaces are heated by heat conduction, and there is less electromagnetic heating, but the utilization efficiency of electromagnetic heating electric energy is higher
However, electromagnetic heating has the problem of unstable heating, and the coil is not fixed stably. If the barrel shakes, the coil is easy to touch the barrel and cause danger.
Moreover, due to the large power required by the mineral refining furnace and the thick electromagnetic coil, the heat dissipation of the coil is also an urgent problem to be solved.
Moreover, the existing refining kiln is prone to structural aging, inconvenient maintenance and difficult transportation due to long-term use

The invention discloses an assembled type mineral aggregate refining kiln. A charging barrel extending in the axial direction penetrates into a heating part shell, and an electromagnetic heating coil is wound outside the charging barrel and does not make contact with the outer wall of the charging barrel; a heat-insulation insulating layer is arranged around the outer side of the charging barrel, and the electromagnetic heating coil is wrapped in the heat-insulation insulating layer which is attached to the outer wall of the charging barrel in a slidable mode; the electromagnetic heating coil is formed by winding a hollow wire, the hollow cavity of the wire is filled with circulating cooling water, and after being powered on, the electromagnetic heating coil generates eddy current in a charging barrel shell and an energy storing core bar in an inductive mode through electromagnetic induction, so that the charging barrel shell and the energy storing core bar are heated. A support structure is arranged on the lower portion of a kiln body, slide rails are arranged on the front side and the rear side of the upper portion of the support structure, and a feeding part and a discharging part are both arranged on the support structure in a slidable mode.
Description
technical field [0001] The invention relates to the technical field of ore refining equipment, in particular to an assembled ore refining kiln. Background technique [0002] Mineral material refining kilns are mainly used in mines, which can carry out preliminary processing of ore powder and improve the mineral precision. Taking iron ore as an example, there are many kinds of iron ore. The main two are magnetite (Fe3O4) and hematite ( Fe2O3), the latter is also commonly known as red ore. my country's iron ore is generally lean ore, with a grade of around 30, and generally requires beneficiation. The beneficiation process of low-grade hematite is complicated and difficult to realize. Therefore, most of the ore dressing in our country is magnetite, which is physical beneficiation, which is easy to realize technically. In order to increase the beneficiation efficiency, the ore is processed before the magnetite is screened, and the impurity iron element in the ore is oxidized...
