Description
Technical field
The present invention relates to a kind of high-temperature dryer for mineral material, be specially adapted to ilmenite concentrate powder that vanadium titano-magnetite obtains or pelletizing carries out hyperthermia drying, and the dryer of roasting can be realized ilmenite concentrate.
Background technology
When at present mineral materials being dried, particularly for the ilmenite concentrate that vanadium titano-magnetite is got through selecting the spoil reclaming after iron, general main employing cylindrical drier or rotary drying machine have come, cardinal principle is that the high-temperature gas formed that burns in burner hearth is passed in rotary drying machine, ilmenite concentrate is also transported in rotary drying machine simultaneously, rotary drying machine rotates and drives ilmenite concentrate to rotate, ilmenite concentrate is overturn in dryer, under the effect of high-temperature gas, ilmenite concentrate is dried, after general oven dry, ilmenite concentrate can reach about 70 degree, if need ilmenite concentrate bake out temperature to reach more than 200 degree, existing equipment can't meet the demands, and adopt some high temperature modes can reach more than 1000 degree as converter carries out sintering temperature to ilmenite concentrate, but because its equipment is complicated, cost is quite high, baking modes for Zhi Xuji Baidu can not meet its requirement.
Summary of the invention
The present invention is that the problems referred to above solved provide a kind of high-temperature dryer for mineral material.
The technical solution used in the present invention is: a kind of high-temperature dryer for mineral material, comprises material bin, support column, heating chamber, and described material bin is body structure, and top is provided with charging aperture and outlet flue, and bottom is provided with discharging opening; Swash plate is provided with in material bin, swash plate is high-end to be connected with material bulkhead, swash plate low side and material bulkhead are formed with leak, material bin inner bottom part is provided with heating plate, and heating plate is for being obliquely installed, and heating plate low side is connected with discharging opening, smoke deflector is provided with in the leak that swash plate and the material bulkhead of heating plate next-door neighbour are formed, smoke deflector bottom is connected with heating plate is high-end, and smoke deflector and material bulkhead form smoke guide port, and the swash plate low side that smoke deflector and heating plate are close to is formed to leak expects mouth; Described support column by spring for described material bin provides resiliency supported; Described heating chamber is arranged on below described material bin, and described heating chamber is the cavity providing heat energy to material bin; Described material bin is also provided with vibrator.
Further, the swash plate in described material bin becomes 6-30 degree with horizontal sextant angle, and described heating plate becomes 6-30 degree with horizontal sextant angle.
Further, the swash plate in described material bin is provided with two or more, and adjacent swash plate becomes to be oppositely arranged.
This high-temperature dryer for mineral material course of work is as follows: material bin is supported by support column by spring, under the vibrator effect of top, mineral powder from charging aperture fall reach swash plate high-end after, under the effect of gravity and vibrator, to the motion of swash plate bottom, then fall lower one deck swash plate from leak.Meanwhile, the high-temperature gas from the heating chamber that smoke guide port is discharged, upwards will flow along orlop swash plate, and arrive on last layer swash plate by leak, finally discharge from charging aperture, can preheat mineral materials in high-temperature gas uphill process, make time of heating shorter below.Material, in swash plate landing process, is fallen on heating plate eventually through leakage material mouth, after heater plate, is discharged from discharging opening.
Further, there is certain angle in described smoke deflector and horizontal vertical direction, make smoke guide port bottom bore be greater than top bore.In general, smoke deflector and the perpendicular angular separation 0-80 degree of level, the high-end swash plate low side higher than heating plate next-door neighbour of smoke deflector.The high-temperature gas that such heating chamber produces, by after smoke guide port, can increase high-temperature gas flowing speed, accelerate the evaporation rate to mineral materials moisture content.
Further, discharge outlet is also provided with material controlling gate, for controlling number and the warm-up time of mineral powder discharging.
