Description
Technical Field
The utility model belongs to the technical field of the molybdenum oxide calcination, especially, relate to a molybdenum oxide calcination returns stove device with cubic material.
Background
The traditional roasting technology of high-solubility molybdenum oxide adopts a reverberatory furnace for roasting, the furnace is a chamber type flame furnace, and the heat transfer mode in the furnace depends on the reflection of flame and more importantly depends on the radiation heat transfer of a furnace top, a furnace wall and a red-hot gas. The charging, discharging and charging stirring during the roasting of the molybdenum concentrate are all manual operations, the charging amount is determined according to the temperature area and the bed capacity of the hearth, the heat utilization of the reverberatory furnace roasting process is low, the fuel consumption is high, and the productivity per hearth area is low. According to the production requirement of ammonium molybdate, the solubility of the raw material high-solubility molybdenum oxide product (the proportion of Mo in MoO3 in the product to the total Mo) needs to be more than 99%. In order to achieve the aim, except for using high-grade molybdenum concentrate, the multi-hearth furnace is specially designed to sieve, crush and recycle and roast blocky materials with the granularity larger than the set requirement. The reason is that molybdenum oxide is agglomerated during the roasting process, the probability of oxidizing MoO2 and high-sulfur products in the materials wrapped in the blocks into MoO3 is reduced, or the MoO3 is reduced into MoO2 due to MOS2 contained in the blocks which are not completely wrapped by the reaction, so that the MoO2 content of the products is increased.
