Abstract
A method of charging a sintering machine with a raw material is provided, the method being effective in inhibiting an "avalanche phenomenon" or an "undercharge phenomenon" from occurring even when the raw material to be sintered has changed in particle size distribution. The method enables stable size segregation of the raw material to be sintered. A raw material to be sintered (8) is fed to the upper end of a slit chute (1) disposed obliquely. Coarse particles (4) are allowed to slip down to a transfer wagon (9) from the lower end of the chute (1), and fine particles (3) which have passed through the slit chute (1) are allowed to slip down to the transfer wagon (9) through a deflector chute (2) obliquely disposed under the slit chute (1). The sintering machine is thereby charged with the raw material. The level of the fine particles (3) accumulated on the deflector chute (2) is always monitored, and the position of the deflector chute (2) relative to the slit chute (1) is regulated so as to keep a proper level. Namely, when the level of the fine particles (3) fluctuates, the deflector chute (2) is brought farther from the slit chute (1). When the level is stable in a position lower than the proper level, the deflector chute (2) is brought near thereto.

But owing to all changing every days such as the kind of raw ore, granularity, proportioning, moisture, so the size-grade distribution of raw materials for sintering is also changing, this makes ratio by slit chute isolating coarse grain of institute and particulate also in variation.Therefore, when the ratio of particulate 3 increased, as shown in Figure 1, the particulate 3 that has passed through the slit chute can be crossed the slope of repose and produce high accumulation on collection chute 2, and caused " snowslide phenomenon: avalanche phenomenon " of avalanche quickly.Consequently, can produce very big change, pack into thereby can not carry out stable particle segregation at particulate layer on mobile trolley used 9 and the boundary position between the coarse grain layer.
On the contrary, when the ratio of the particulate in the raw materials for sintering 3 reduces, as shown in Figure 2, the amount of the particulate 3 on collection chute 2 can become insufficient, the particulate layer that is deposited on the collection chute can disappear, thereby lose the concavo-convex effect of filling up, thereby cause " loading not foot phenomenon " the coarse grain laminar surface.When " load not foot phenomenon: undercharge phenomenon " took place, the surface of the particulate layer on mobile trolley used 9 became concavo-convex, still can not carry out stable particle segregation.
Therefore, in patent documentation 1, be provided with finer and closely wovenly on top, be provided with thicklyer, thereby realize that good particle segregation packs in the bottom by gap length with slit chute 1.
In addition, in patent documentation 2, below slit chute 1 and collection chute 2, extension slot is set, by changing its length, thereby realizes that good particle segregation packs into.

Embodiment
Below, the present invention will be described.
Fig. 3 is the explanatory view of embodiments of the present invention.On the slit of tilted configuration chute 1, flatly be provided with a plurality of slits bar with the interval of stipulating, and between adjacent separately slit bar, form the slit.In the vertical lower of slit chute 1, be provided with the collection chute 2 that is similarly tilted configuration.Raw materials for sintering is fed into from raw materials for sintering hopper 5, via roll feeder 6 and helps on the starting chute 7, and from the upper end of slit chute 1 to the lower end landing.Raw materials for sintering 8 forms by mixing coke and other auxiliary material and carry out damping in iron ore, and its particle diameter is about 0.01～10mm.During landing downwards on the slit chute 1, the particulate 3 in the raw materials for sintering 8 drops to from the slit on the collection chute 2 at raw materials for sintering 8, and coarse grain 4 can not fall from the slit, but directly arrives the lower end of slit chute 1.
Particulate 3 and coarse grain 4 are the relative concepts that determined by the width of mesh of slit chute 1.In general sintering material for iron manufacturing, how particle diameter is called particulate 3 in the scope of 0.01～2mm, and particle diameter is surpassed 2mm and is called coarse grain 4 until the scope of 10mm, in explanation of the present invention, also comply with this definition.
Below slit chute 1 and collection chute 2, sinter machine mobile trolley used 9 from the left side of Fig. 3 to right-hand walking.Coarse grain 4 directly drops on mobile trolley used 9 from the lower end of slit chute 1.On the other hand, dropping to particulate 3 on the collection chute 2 on one side, also to form on one side the fine build-up layer on collection chute 2 mobile downwards, thereby on mobile trolley used 9 and in the lower floor that is made of coarse grain 4, form the upper strata that is made of particulate 3 continuously.Collection chute 2 is provided with in the interval constant mode between its lower end and mobile trolley used 9, thereby even the thickness of lower floor has change, also as shown in Figure 3, the degree of depth that comprises the raw materials for sintering 8 upper strata, that pack into that is made of particulate 3 can be kept constant.
But as previously mentioned, all changing size-grade distribution every day of raw materials for sintering, and this makes ratio by slit chute isolating coarse grain of institute and particulate also in variation.Therefore, when the ratio of particulate 3 increased, as shown in Figure 1, particulate 3 can be crossed the slope of repose and produce high accumulation, thereby " snowslide phenomenon " of avalanche quickly takes place on collection chute 2.
On the contrary, when coarse-grained ratio increased, as shown in Figure 2, the accumulation horizon of the particulate on collection chute 2 can disappear, and loses the concavo-convex function of filling up to the coarse grain laminar surface, thereby causes " loading not foot phenomenon ".
Therefore, in the present invention, as shown in Figure 3, between slit chute 1 and collection chute 2, the Charge level measurer 10 that the material level that is deposited in the particulate 3 on the collection chute 2 is detected is set, the material level that is deposited in the particulate 3 on the collection chute 2 is carried out frequent detection, and change the level attitude of collection chute 2 with respect to slit chute 1 according to the change conditions of its material level.As Charge level measurer 10, can use the known rang sensor that has utilized laser, infrared rays, ultrasonic wave etc.The material level (material level of accumulating amount) that is deposited in the particulate 3 on the collection chute 2 can be held by the distance the upper end position from Charge level measurer 10 to the particulate of piling up.The output of Charge level measurer 10 is transported in the control device 11; Change based on material level, the accumulation situation of the raw materials for sintering on 11 pairs of collection chutes 2 of control device is easy to generate state, or the standard state or be to load easily not the state of foot phenomenon to judge of snowslide phenomenon, thereby makes collection chute 2 mobile in the horizontal direction.
Raw materials for sintering on the collection chute is piled up the judgement of situation for example can be scheduled to a suitable material level scope, and will within this material level scope, be set at standard state, when surpassing this scope, be set at the state of avalanche prone phenomenon, and when not reaching this scope, be set at the easy not state of foot phenomenon that loads.
In addition, when the material level of the particulate 3 on being deposited in collection chute 2 repeats big cyclical movement (for example in Fig. 5), it is judged as accumulation horizon " snowslide phenomenon " of avalanche quickly takes place; And the position of the particulate 3 on being deposited in collection chute 2 is being lower than when stopping the regular hour on the position of preposition scope, and it is judged as the particulate that takes place not to be piled up on the collection chute " loading not foot phenomenon ".
The structure of portion of collection chute travel mechanism 20 is not special to be limited.For example as shown in Figure 4, can adopt following mechanism: on fixed rack 12, carry the support chassis 13 of collection chute 2 in mobile mode freely, and by being arranged on handle 14 these support chassis 13 of operation on the fixed rack 12 and making it mobile.Also can adopt following structure: by handle 14 pinion(gear) is rotated, thereby move from supporting chassis 13 extended tooth bars 15; Perhaps, from supporting on the chassis 13 extended poles the good screw thread of car in advance, and be meshed with the screw that is rotating owing to the effect of handle 14 produce mobile.Certainly, also can be without staff, but make and support chassis 13 to produce to move by motor etc. is set.At this moment, as long as material level signal detected by Charge level measurer, the relevant particulate of piling up is supplied to control device 11, and calculate by the miles of relative movement of 11 pairs of collection chutes of control device, then the signal of relevant this miles of relative movement is supplied to portion of collection chute travel mechanism 20 and get final product.Thus, can with the material level of the particulate of piling up interlock the and automatically position of collection chute 2 being adjusted automatically mutually.
According to such travel mechanism, can under situation about not stopping operation, the position of collection chute 2 be adjusted.
Under the situation of the state that is in the avalanche prone phenomenon, as long as by means of portion of collection chute travel mechanism 20, make collection chute 2 and slit chute 1 away from getting final product; And be under the easy situation of loading the state of foot phenomenon not, as long as collection chute 2 and slit chute 1 are close.This be because: " snowslide phenomenon " means superfluous accumulation on collection chute 2, so reduce accumulation as long as collection chute 2 is retreated; And " loading not foot phenomenon " means the accumulation deficiency on the collection chute 2, so as long as make collection chute 2 near and increase accumulating amount.
At this, the suitable material level of the accumulating amount on the collection chute is along with the difference of proterties such as the granularity of raw materials for sintering, proportioning, moisture and change.Therefore, can be based on proportioning of raw materials for sintering etc., the form of the proper range that is prepared in advance is set suitable material level.Under the situation of general raw materials for sintering, its suitable material level is: 2 positions of rising about about 200mm from the uppermost surface that is deposited in the raw materials for sintering on mobile trolley used 9 along collection chute.
Specific embodiment to device shown in Figure 3 describes.When the amplitude of fluctuation of being confirmed by Charge level measurer 10, be deposited in the upper end position of the particulate on the collection chute (along the amplitude of fluctuation of collection chute 2) is 50mm when above, confirm as " snowslide phenomenon ", and with 1～3 times amount of movement of the slit amplitude of slit chute 1, make collection chute 2 and slit chute 1 away from.In addition, when 10 that confirmed by Charge level measurer, as to be deposited in the particulate on collection chute upper end position from suitable material level (the raw materials for sintering uppermost surface on mobile trolley used is the position of 200mm along collection chute) when dropping to above the position more than the 50mm, confirm as " loading not foot phenomenon ", and make collection chute 2 near slit chute 1 with 1～3 times amount of movement of slit amplitude.
By such control, with the snowslide phenomenon of every month with load not that the generation number of packages of foot phenomenon is reduced to 0 significantly from average being about 15.Consequently, obtained being approximately the effect of increasing production of 1% agglomerate.This numeral seems not quite, but in fact is equivalent to produce about 5000 tons volume increase per month, so have very big practical function.
Can confirm from foregoing, even the size-grade distribution at raw materials for sintering is all changing every day, thereby make by the slit chute under the ratio of isolating coarse grain and the particulate situation about changing, also can prevent " snowslide phenomenon " and " loading not foot phenomenon ", thereby on mobile trolley used 9, with the lower floor is that coarse grain 4, upper strata are the mode of particulate 3, stably carries out the particle segregation of raw materials for sintering and packs into.Consequently, needn't as in the prior art, stop operation, can not reduce the operation factor of device and obtain the agglomerate of better quality, thereby can seek the raising of the productivity of blast furnace.
Utilizability on the industry
The present invention can make in the operation at the sintering of iron-smelting raw material and be applied. By using the present invention, can in the situation of the productivity ratio that does not reduce sintering raw material feeding device, obtain high-quality sintering deposit, thereby help to improve comprehensive ironmaking production rate.
