Abstract
This invention relates to a device for smoothing the surface of a sinter mixture in a grate carriage (1), before the same enters an ignition furnace (2), by means of at least one scraper (3) between the charging point (4) of the sinter bed mixture and the ignition furnace (2), wherein the at least one scraper (3) is suspended above the travelling way (5) of the grate carriage (1) so as to reciprocate in and against its direction of travel such that the scraper (3) drags along the sinter bed surface when the grate carriage (1) moves through below the same.
Description
Technical field
The present invention relates to a kind of device, for come the surface of equating grid section chassis sinter mixture before entering into ignition furnace at the grid section chassis by means of the movable loading point at sinter mixture and at least one scraper between ignition furnace.
Background technology
During the sintering of ironmaking, the fine ore that still can not use immediately and concentrate should be lumpd, so that they can be supplied to blast furnace ironmaking process subsequently.For the sintering purpose, prepare sinter mixture, the coke that sinter mixture comprises iron ore, gathers materials and acts as a fuel, and by feeder, be installed on the grid section chassis of the sinter machine circulated with the endless belt form.The coke be included in sinter mixture is lighted, and be arranged on extractor fan below grid section chassis band the burning flame front suction by sinter mixture, in order to obtain the sinter cake of perfect combustion at the exhaust end place of band.Due to the heat produced during the course, fine ore will melt from the teeth outwards, so that their crystal grain connects securely.With after sinter return fine separates, the finished product agglomerate is supplied to blast furnace at rustization layer.
When sinter mixture being loaded on the grid section chassis, longitudinal fluting and transverse concave groove have been formed on the surface of sinter bed.From the reason of technique, consider, these grooves are undesirable, because they affect the firing characteristic of ignition furnace and because they are influential to ventilating.In order to eliminate such surface irregularity, what use up to now is the scraper of installing rigidly always.The shortcoming of this scraper is: when sinter mixture moves through below scraper along flow direction, damming can occur and be sheared in sinter mixture.Like this, the sinter mixture surface has produced undesirable compacting, and this has hindered good ventilation.
Summary of the invention
The objective of the invention is: in the situation that there is no the shortcoming of prior art, eliminate the lip-deep undesirable unfairness of sinter mixture, thus and the quality product of raising sintered material.
According to the present invention, basically realizing this purpose in device as mentioned above, wherein, at least one scraper of track overhung of advancing at the grid section chassis, so that along the direct of travel to-and-fro movement with against the grid section chassis, thereby scraper draws and scrapes along the sinter bed surface when the grid section chassis moves through below described scraper.
In this way, just realized the unfairness on equating sinter bed surface before the grid section chassis enters into ignition furnace, and the material damming can not occur and can not produce undesirable compacting, thereby guaranteed even some fire behavior and the desirable ventilation in the ignition furnace.Due to this special reciprocating scraper, so avoided material the overflowing on grid section chassis sidewall that can occur in the prior art.
Valuably, except to-and-fro movement, scraper can carry out the swaying motion., although only but to-and-fro movement crosses with regard to equating the ripple (shear wave) that grid section chassis direct of travel extends basically, the ripple (compressional wave) basically extended along the sinter bed surface longitudinal has been eliminated in the swaying motion of scraper.
Valuably, a plurality of corresponding narrower scrapers can be suspended on the track top across the width distribution of the track of advancing of advancing of grid section chassis with embarking on journey side by side.
In addition, for the different sinter bed height in the grid section chassis, useful is that the height of scraper above the described track of advancing is adjustable.
The supporting power of scraper is basically by himself weight decision.
Yet, also one or more counterweights can be installed on scraper, in order to produce or adjust required supporting power.
In particular aspects of the present invention, for example can by cam plate, camshaft or crank driving device and/or pneumatically or fluid power realize the swaying motion of scraper.
Scraper can be by metallic substance or non-metallic material manufacture, and can have different shapes.
Start and maintain the to-and-fro movement of scraper while moving through below scraper for the grid section chassis when accommodating sinter mixture, useful especially is that scraper is angled or crooked along the direct of travel of grid section chassis at its free end.
Can understand other purpose of the present invention, feature, advantage and possible application from the following description to embodiment and accompanying drawing.Describe and/or illustrated whole feature self or combination arbitrarily all form theme of the present invention, and no matter they whether be included in each claim and/or they after quote.
The accompanying drawing explanation
In accompanying drawing:
Fig. 1 has shown the schematic side elevation for the device on equating grid section chassis sinter mixture surface before entering into ignition furnace at the grid section chassis of the present invention, and
Fig. 2 has schematically shown the oblique drawing of this equating device, and the grid section chassis is arranged below the equating device.
Embodiment
As shown in Figure 1, the direct of travel of grid section chassis 1 from the movable loading point 4 of sinter mixture to ignition furnace 2 is to extend from left to right.Above the track 5 of advancing of grid section chassis 1, one or more scrapers 3 hang and embark on journey abreast across the width of grid section chassis 1, with the rotation D to-and-fro movement around crossing grid section chassis 1 direct of travel, while moving through below scraper with convenient grid section chassis 1, scraper draws and scrapes along the sinter bed surface, and therefore removes any transverse wave of existence.
By means of the oscillatory driver 6 shown in Fig. 2, scraper 3 can carry out the swaying motion, so that the longitudinal ripple that equating sinter bed surface exists.Can by cam plate, camshaft or crank driving device (at length not illustrating) and/or pneumatically or fluid power realize the swaying motion of scraper 3.
As seen from Fig. 1, it is slightly angled or crooked that scraper 3 will rest the lip-deep free end of corresponding sinter bed 7 places at it, while moving through below scraper with convenient grid section chassis, can easily start and maintain to-and-fro movement.Free end for example also can be formed the rake shape, in order to improve the equating effect and make the equating effect more even.
In order to be adapted to different bed depths, scraper 3 can be respectively or is arranged on together the different heights place, and/or can regulate the height of scraper 3 above the track 5 of advancing.
The supporting power of scraper 3 is basically by himself weight decision.Yet, can change by additional counterweight (not shown) the supporting power of scraper 3.
