Abstract
The invention discloses a ring-type pellet dryer comprising a rotator frame and driving devices driving the rotator frame to rotate. A regulating part for controlling the rotator frame to operate and rotate in accordance with a rotation center is arranged on the inner side of the rotator frame, trolleys capable of turning over and used for pavement of green pallets are mounted on the rotator frame, and a drying device is arranged below the rotator frame. The ring-type pellet dryer is simplified, cost is lowered, cost of the ring-type pellet dryer is lowered by 15-25% as compared with that of a chain grate machine of the same specification, land occupation is reduced by more than 50%, and land acquisition cost and civil engineering investment are reduced greatly; cost is reduced from all sides; the ring-type pellet dryer is in annular continuous operation, empty return trolleys are avoided, total heat-radiating area is small, a hot-air pipeline is shortest, and heat loss due to radiation is lowered to the highest degree.
Description
Technical field
A drying machine, particularly a kind of ring type pelletizing drying machine.
Background technology
Current domestic lateritic nickel ore pelletizing process mainly adopts drying grate as the drying equipment of pelletizing, and the grate of drying grate is dragged by flexible gearing, through dried pelletizing, runs to terminal, and the shovel flitch of process drying grate has unloaded dry run.Drying grate has following some deficiency for being dried: the drying grate of same specification is twice above than ring drier occupation of land; Drying grate is higher than ring drier price; Drying grate part is many, and equipment failure rate is high; Drying grate takes up an area greatly, factory building height is large, construction investment is high; The part of drying grate has several ten thousand, and spare parts consumption is large, and operating cost is high.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of simplified equipment, reduced cost, equipment price has reduced 15-20% than same specification drying grate, takes up an area and saves more than 50%, has significantly reduced land expropriation cost and construction investment; Reduced from every side cost.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
Ring type pelletizing drying machine, comprise: revolving body framework, drive the drive unit of revolving body framework rotation, revolving body framework inner side is provided with controls revolving body framework according to a centre of gyration rotating regulating part that turns round, on revolving body framework, be provided with turningly and for spreading the chassis of green-ball, revolving body framework below is provided with drying device.
Aforesaid ring type pelletizing drying machine, also comprises: connect chassis and promote the pushing component of trolley movement.
Aforesaid ring type pelletizing drying machine, pushing component forms to be had: be installed on the crank of chassis inner shaft, crank end is provided with the pinch roller of controlling chassis upset.
Aforesaid ring type pelletizing drying machine, drying device is for draining bellows.
Aforesaid ring type pelletizing drying machine, drive unit is pin tooth driving device.
Aforesaid ring type pelletizing drying machine, regulating part is side blocking roller.
Usefulness of the present invention is: the invention provides a kind of simplified equipment, reduced cost, equipment price has reduced 15-20% than same specification drying grate, takes up an area and saves more than 50%, has significantly reduced land expropriation cost and construction investment; Reduced from every side cost; Equipment is annular continuous operation, there is no the empty chassis of backhaul, and total area of dissipation is little, and hot-blast pipe line is the shortest, has at utmost reduced radiation loss.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of embodiment of the present invention;
Fig. 2 is the front view of a kind of embodiment of pin tooth driving device of the present invention;
The implication of Reference numeral in figure:
1 revolving body framework, 2 pin tooth driving devices, 3 side blocking rollers, 4 chassis, 5 drain bellows, 6 pinch rollers.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Ring type pelletizing drying machine, comprise: revolving body framework 1, drive the drive unit of revolving body framework 1 rotation, as a kind of preferred, drive unit is pin tooth driving device 2, revolving body framework 1 inner side is provided with controls revolving body framework 1 according to a centre of gyration rotating regulating part that turns round, as a kind of preferably, regulating part is side blocking roller 3; On revolving body framework 1, be provided with turningly and for spreading the chassis 4 of green-ball, revolving body framework 1 below is provided with drying device, as a kind of preferably, drying device is for draining bellows 5.Use chassis 4, the part of comparing same specification chain grate machine has several ten thousand, and the sum of the revolving body of this equipment and chassis 4 parts only has hundreds of part, and durability improves, and fault rate significantly reduces; Equipment is annular continuous operation, there is no the empty chassis 4 of backhaul, and total area of dissipation is little, and hot-blast pipe line is the shortest, has at utmost reduced radiation loss.
Ring type pelletizing drying machine, also comprises: connect chassis 4 and promote the pushing component that chassis 4 moves; Pushing component forms to be had: be installed on the crank of chassis 4 inner shafts, crank end is provided with the pinch roller 6 of controlling chassis 4 upsets.
Ring type pelletizing drying machine adopts pin tooth driving device 2 to drive 1 rotation of revolving body framework, and the inner side of slewing frame is provided with side blocking roller 3, is used for controlling slewing frame and turns round according to a centre of gyration.Turnover chassis 4 is arranged on slewing frame, as shown in Figure 2, a crank is installed on the inner shaft of each chassis 4, crank end arranges the pinch roller 6 of a control chassis 4 upsets, during operation, pinch roller 6 makes chassis 4 keep level operation under the constraint of pressing rail, chassis 4 is after entering cloth district, and the green-ball of spreading suitable thickness on chassis 4 carries out drying operation.The upper cover of down-draft drying zone is through the hot blast of 350～400 ℃ of top backheat wind pipeline inputs, and due to the suction function of lower air draft pipe, hot blast enters the pelletizing bed of material pelletizing is dried, and through the useless flue gas after the bed of material, by lower air draft pipe, is taken away.The pelletizing that chassis 4 has carried after dry run continues operation, the pinch roller 6 of chassis 4 inner sides enters the upper notch of pressing rail, chassis 4 car body lay particular stress on and above the weight effect of pellet under automatically tumble downwards, complete discharge process, after discharging, pinch roller 6 is along pressing rail curve motion, chassis 4 returns to level, and then cloth again, enters next circulation.
The invention provides a kind of simplified equipment, reduced cost, equipment price has reduced 15-20% than same specification drying grate, takes up an area and saves more than 50%, has significantly reduced land expropriation cost and construction investment; Reduced from every side cost; Equipment is annular continuous operation, there is no the empty chassis 4 of backhaul, and total area of dissipation is little, and hot-blast pipe line is the shortest, has at utmost reduced radiation loss.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
