Description
Technical field
This utility model relates to DRI chiller, belongs to field of smelting.
Background technology
Rotary hearth furnace Direct Reduction Technology is as one of the major technique of non-blast furnace ironmaking, and it is good with the simple and economical property of flow process
Common concern is obtained Deng superiority.Iron-bearing material and coal dust or other carbonaceous material, binding agent are mixed evenly to prepare and contain by this technique
Carbon pellets is also dried, and directly pelletizing is layered on rotary hearth furnace without roasting, in in-furnace temperature 1200～the reducing zone of 1300 DEG C
Territory is reduced to metallized pellet.Higher from rotary hearth furnace reducting pellet temperature out after completion of the reaction, reach about 1000 DEG C, for side
Just the storage of reducting pellet and transport, need to be cooled down high temperature pelletizing by chiller.
According to the applicant understood, cylinder cooler is the direct reduced iron by rotary hearth furnace cooling device that operation strategies is the widest, but circle
Cylinder cooler there is also problems with:
1. cylinder cooler is cooling indirectly, and cooling effectiveness is low, for ensureing that cooling effect needs to increase the length of cooling device
Degree, cost of investment is higher.Additionally protective gas and water consumption the most therefore can be bigger；
The most for above-mentioned reasons, high temperature pelletizing needs longer cool time in cylinder cooler, thus causes pelletizing
Between interaction time longer, chip index is higher；
3., in sub-cooled section, owing to pelletizing cooling is nearly completed, the intensity of pelletizing increases, and causes pelletizing cold with cylinder
But machine is bigger to the abrasion of cylinder when of rotation.
Utility model content
Utility model purpose: in order to overcome the deficiencies in the prior art, this utility model provides one direct-reduction
Ferrum chiller, is cooled down DRI by segmentation, good cooling results, and efficiency is high.
Technical scheme: for solving above-mentioned technical problem, a kind of DRI chiller of the present utility model, including the
One high temperature chain mat machine and the second high temperature chain mat machine, the head at the first high temperature chain mat machine is provided with rotary hearth furnace chute, rotary hearth furnace chute
In DRI unload to the first high temperature chain mat machine, described first high temperature chain mat machine be arranged over DRI is entered
The spray cooling device of row cooling, is cooled to 1000～500 DEG C by DRI, and the afterbody at the first high temperature chain mat machine is provided with
The rake teeth broken up by DRI, DRI is by the slideway dropping into inclination after breaing up, and slideway is provided with several
The vertical bar being interspersed, slideway is arranged over the first spray cooling device, DRI is carried out cooling twice, at slideway
Lower section is provided with the second high temperature chain mat machine, is provided with surge bunker, the direct-reduction in surge bunker below the afterbody of the second high temperature chain mat machine
Ferrum is transported by the heat resistant adhesive tape machine of lower section.
As preferably, the upper rear of described second high temperature chain mat machine is provided with temperature-detecting device.
As preferably, described slideway is connected with vibrating motor, and vibrating motor band sliding way vibrates.
As preferably, described second high temperature chain mat machine is provided with the second spray cooling device.
Beneficial effect: DRI chiller of the present utility model, by using spray cooling in high temperature section, should
Section intensity of cooling is low, and high temperature pelletizing temperature will not drastically reduce and cause pelletizing efflorescence, and low-temperature zone uses spraying cooling, and cooling is strong
Spend higher；Afterbody at the first high temperature chain mat machine is provided with rake teeth, and the reducting pellet of lower floor can be made to expose, and cooling is more uniform, subtracts
Shao Liao localized hyperthermia；By will direct-reduction pulvis ferri (ferrosic oxide) on slideway, by collision further cooling, good cooling results.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of DRI chiller of the present utility model, including the first high temperature chain mat machine 3 and the
Two high temperature chain mat machines 8, the head at the first high temperature chain mat machine 3 is provided with rotary hearth furnace chute 1, the direct-reduction in rotary hearth furnace chute 1
Ferrum unloads to the first high temperature chain mat machine 3, the spray being arranged over cooling down DRI of described first high temperature chain mat machine 3
Fog cooling apparatus 2, is cooled to 1000～500 DEG C by DRI, and the afterbody at the first high temperature chain mat machine 3 is provided with directly also
Former stable scattered rake teeth 4, DRI is by the slideway 5 dropping into inclination after breaing up, and slideway 5 is provided with several staggered point
The vertical bar 7 of cloth, slideway 5 is arranged over the first spray cooling device 6, DRI is carried out cooling twice, in slideway 5 times
Side is provided with the second high temperature chain mat machine 8, is provided with surge bunker 9 below the afterbody of the second high temperature chain mat machine 8, directly going back in surge bunker 9
Former ferrum is transported by the heat resistant adhesive tape machine 10 of lower section.
In this utility model, the upper rear of described second high temperature chain mat machine 8 is provided with temperature-detecting device, slow to falling into
The temperature of the DRI rushing storehouse 9 detects, if temperature is too high, and the first spray cooling device 6 enlargement discharge, if mistake
Low, reduce flow.Described slideway 5 is connected with vibrating motor, and vibrating motor band sliding way 5 vibrates, will direct-reduction by vibration
Ferrum is preferably sent in the second high temperature chain mat machine 8.Described second high temperature chain mat machine 8 is provided with the second spray cooling device, as
Really temperature is too high, can lower the temperature DRI further.
The above is only preferred implementation of the present utility model, it should be pointed out that: for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and
Retouching also should be regarded as protection domain of the present utility model.
