Description
Technical field
The utility model belongs to fine ore drying oven technical field, and a kind of simple, compactness and reliable drying device particularly are provided, to moisture fine ore carry out layering, continuously, highly effective drying.
Background technology
In the pelletizing industry, require iron ore concentrate moisture≤8%, therefore, need carry out drying to iron ore concentrate, adopt horizontal drying usually.In process of production, find to exist following weak point:
1. the easy putty of drying charging chute.The drying inclination angle is 2～3 °, under drive device drives, rotates; Iron ore concentrate is dropped into into drying through the free skating of charging chute, because iron ore concentrate is moisture and iron ore concentrate freely moves down along barrel, the putty phenomenon often takes place the charging chute.
2. drying efficiency is not high.Hot blast blasts drying and divides the discharging terminal drum to go into feed end to blast, blast from discharge end, although hot blast and iron ore concentrate antikinesis, hot blast is difficult to arrive the drying feed end; Blast from feed end, hot blast and iron ore concentrate direct motion, hot blast contacts abundant inadequately with iron ore concentrate; Two kinds of bulging hot blast mode drying efficiencies are all not high.
3. floor space is big, and energy consumption is high.The bigger usually occupation of land of horizontal drying, volume is many; Own wt is big, and weight is bigger behind the iron ore concentrate of packing into, requires the power height that drives.
Facts have proved that the pattern of drying oven and structure play crucial effects at the fine ore drying process.Therefore, researching and developing new and effective drying oven is needing when affair.
Summary of the invention
The purpose of the utility model is to provide a kind of layering, continuous fine ore drying oven, makes moisture fine ore be dried to the moisture of requirement.
The utility model fine ore drying oven comprises body of heater, gear reduction box 1, shaft coupling 2, fine ore charging aperture 3, Waste gas outlet 4, double helix 5, seal cover 6; Bearing and base 7, dividing plate 8, hot blast air inlet 9, fine ore discharge gate 10, drive motors 11, dividing plate feed opening 12; Body of heater designs the double helix 5 of 2.5 ° of four inclination layers from top to bottom, and biserial arranges that separated by dividing plate 8 between every layer, dividing plate is consistent with the double helix inclination angle; Double helix 5 two ends are fixed through bearing and base, and axle is provided with seal cover 6 with the drying oven sidewall of the furnace body; Gear reduction box and double helix 5 are connected by shaft coupling, and dividing plate inclination bottom is provided with dividing plate feed opening 12.
Body of heater is cuboid.
Every layer of double helix drive unit is made up of drive motors 11, gear reduction box 1 and shaft coupling 2; Ground floor double helix drive unit and the 3rd layer of double helix drive unit design are in the body of heater left side, and second layer double helix drive unit and the 4th layer of double helix drive unit design are separated by dividing plate 8 between every layer on the body of heater right side.
One, three layers of dividing plate design in the same way, and two, four layers of dividing plate design in the same way, and one, three layer of dividing plate and two, four layers of dividing plate subtend design.
Under the drive of drive motors, double helix run-in synchronism, its main feature is:
Every grade of double helix of the drying oven of the utility model promotes the fine ore operation, and fine ore is stirred immixture in addition, and fine ore runs to dividing plate feed opening 12 along dividing plate 8 and falls into subordinate's double helix, so circulation.
Hot blast blasts from bottom of furnace body hot blast air inlet 9, discharges from furnace roof Waste gas outlet 4, and hot blast moves against fine ore, fully contacts the realization heat exchange with fine ore.
This stove is applicable to metal fine ore and nonmetal fine ore drying.
1. four layers of double helix biserial are arranged
From top to bottom, ground floor double helix and the 3rd layer of double helix drive unit are in body of heater left side (diagram), and second layer double helix and the 4th layer of double helix drive unit are on the body of heater right side (diagram), and drive unit is made up of drive motors 11, gear reduction box 1 and shaft coupling 2; Separate by dividing plate between every layer; Every layer of double helix is 2.5 ° of inclination angles with corresponding dividing plate to be installed, and bottom, dividing plate inclination angle is provided with feed opening, is convenient to fine ore and falls into lower floor; Four layers of double helix biserial are arranged.
2. materials flow and hot blast antikinesis
The fine ore material feeds from drying oven top fed mouth, and operation to the right runs to the dividing plate feed opening and falls into the second layer under the ground floor double helix promotes, and operation left under second layer double helix promotes again is so that fall into the 3rd layer again.Hot blast blasts from dry body of heater bottom left, gets into the 3rd helical layer against the materials flow direction from the 3rd layer of dividing plate feed opening, so that discharge from the upper of furnace body Waste gas outlet at last.
3. drying efficiency is high
Materials flow and hot blast antikinesis, spiral not only has impetus to fine ore, also has agitaion, helps hot blast fully to contact with fine ore; Simultaneously, hot blast makes the inner heating of whole body of heater, comprises dividing plate, and dividing plate also has heat effect to the fine ore of operation, and body of heater has need of stoving to fine ore.So that it is fine ore is had bad luck for four times in drying oven, dry by fully.
4. maintenance is convenient
Both helical ends is by bearing and base support, and two of bodies of heater are offered the mouth bigger slightly than double helix lateral dimension, is convenient to spiral and hauls out and overhaul, safeguard; Axle is sealed by seal cover with the body of heater both sides, and anti-hot blast, dust are revealed.
5. immixture
Double helix promotes the fine ore operation, and helical blade also has agitaion to fine ore, and fine ore is had immixture.
