Abstract
The utility model relates to a wet molybdenum concentrate drying and roasting system, which comprises an internal-heating type rotary kiln, a flash dryer and a material receiver, wherein a first feeder is arranged at the feeding hole of the flash dryer; the discharging hole of the flash dryer is communicated with the feeding hole of the material receiver by a pipeline; a second feeder is arranged at the feeding hole of the internal-heating rotary kiln; the feeding hole of the material receiver is communicated to a feed hopper of the second feeder by a pipeline; and an air blower is arranged on an exhaust pipeline of the material receiver. The system is characterized in that a hot air pipeline is arranged between a kiln tail ash bin of the internal-heating type rotary kiln and the air inlet of the flash dryer; and a valve is arranged on the hot air pipeline. The system has the advantages that the flash dryer can directly obtain the residual heat at the kiln tail of the internal-heating type rotary kiln as the heat source for drying wet molybdenum concentrate, thereby not only improving the utilization rate of the energy source, lowering the production cost of the molybdenum concentrate and saving large amount of energy source, but also avoiding the unnecessary impurities in the drying stage of the molybdenum concentrate; moreover, the drying capacity can completely meet the production requirement.
Description
Technical field
The utility model is particularly related to a kind of wet concentrated molybdenum ore oven dry roasting system.
Background technology
At present, the drying and roasting system of domestic concentrated molybdenum ore generally adopts flash dryer and internal heat type rotary kiln, concentrated molybdenum ore adds flash dryer through charging machine, mix with warm air after entering flash dryer, material forms the particulate state fluidization under the effect of warm air and mechanical dispersion power, being the high dispersing state is present in the warm air, concentrated molybdenum ore and warm air thorough mixing, moment is finished the caloic exchange, drying process is fast and abundant, drying is after collector, and concentrated molybdenum ore is collected, and obtains powder-like product and enters rotary kiln baking.The used flash dryer of present this dehumidification system all is provided with independently thermal source, the general indirect heat exchange hotblast stove that adopts provides dry required heat energy, and its shortcoming is that energy consumption is higher, and the hotblast stove coal consumption amount is big, increase the roasting cost of concentrated molybdenum ore greatly, wasted the energy.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of rate of energy that improves will be provided, and reduces the roasting cost of concentrated molybdenum ore, the wet concentrated molybdenum ore oven dry roasting system of save energy.
The utility model is achieved in that it comprises the internal heat type rotary kiln, flash dryer and collector, opening for feed at flash dryer is provided with first feeding machine, the discharge port of flash dryer and the opening for feed of collector pass through pipeline connection, opening for feed at the internal heat type rotary kiln is provided with second feeding machine, the discharge port of collector passes to the hopper of second feeding machine by pipeline, on the exhaust line of collector, be provided with blower fan, its special character is: be provided with a hot-blast pipe line between the blast inlet of the kiln tail ash bin of internal heat type rotary kiln and flash dryer, be provided with valve on described hot-blast pipe line.
Above-mentioned wet concentrated molybdenum ore oven dry roasting system is provided with chapelet and scraper conveyor successively between the discharge port of collector and second feeding machine.
Above-mentioned wet concentrated molybdenum ore oven dry roasting system, described collector is a bagroom.
Above-mentioned wet concentrated molybdenum ore oven dry roasting system, described first feeding machine and second feeding machine are screw feeder.
