Description
Technical field
The present invention relates to and detect leaking out of the pallet chassis that uses when manufacturing the sintering deposit of blast furnace raw material, and detect the technology of the damage of pallet chassis.
Background technology
Use Figure 11 and Figure 12, the manufacturing equipment (hereinafter referred to as sintering machine) 20 of the sintering deposit as blast furnace raw material is described.As shown in figure 11, sintering machine 20 has multiple pallet (pallet) chassis 6, and it connects setting in the direction of movement continuously, mobile along Long Circle surround orbit (Japanese: circumference Rail road).The box-formed shape that this pallet chassis 6 opens for top, delivers the raw material of aftermentioned sintering deposit.In the bottom surface of pallet chassis 6, as shown in figure 12, be formed with the ventilating part 6a of such as grid shape, raw material not by but ventilative.As shown in figure 11, below the track of pallet chassis 6, adjoin with the moving direction of pallet chassis 6 and be fixedly installed multiple bag-shaped bellows (wind box) 7.The upper opening portion of bellows 7, opposed with the ventilating part 6a of pallet chassis 6.In the example in the figures, the bag-shaped airduct (wind leg, two breeches pipes) 8 being branched off into two bursts of shapes is formed in the below of bellows 7.Each airduct 8 is connected with main pipeline 9.Main pipeline 9 is connected with getter devices 11 such as air blasts.When driving getter device 11, air circulates downwards from the top of pallet chassis 6.In order to prevent leaking out between the pallet chassis 6 of movement and bellows 7, and in the lower end of pallet chassis 6, can install movably and the sealing gland bar of the upper-end contact of bellows 7 (Japanese: エ ア シ ー Le バ ー) 10 by above-below direction, apply heat-resisting grease at sealing gland bar 10 and the contact site of pallet chassis 6.
Store respectively in multiple raw material tank 1 and comprise iron ore, coke, each raw material of the sintering deposit of lime stone.Blender 2 for adding the mixing of moisture limit to the above-mentioned each raw material limit supplied from raw material tank 1, and makes particle.The raw material being made particle by blender 2 is dropped into buffering hopper (surge hopper) 3, and recycling is arranged at the rotary drum dispenser 4 of buffering hopper 3 lower end, loads pallet chassis 6, as shown in figure 12, and forms raw material layer 99.In the downstream position adjacent with rotary drum dispenser 4, configuration has the ignition furnace 5 of multiple burner, utilizes electric fire with improved internal 5 to the raw material igniting loading pallet chassis 6.When the top from raw material layer 99 downwards ventilating air time, in raw material layer 99 coke burning, utilize the combustion heat that raw material layer 99 is sintered from the top to the bottom in turn.Along with the movement of pallet chassis 6, continue raw materials for sintering layer 99, through about 30 ~ 50 minutes, generate sintering deposit continuously.In addition, pallet chassis 6 is 100 ~ 160, and pallet chassis 6 is 1 hour ~ 1 and a half hours around the time needed for surround orbit one week.
But along with the use of pallet chassis 6, the inside upper part 6d of end-face lining plate (liner) 6c below the sidewall 6b being positioned at pallet chassis 6, is pruned because of the friction between the raw material that drops from top raw material layer.Like this, diminish at the inside upper part 6d part aeration resistance of the end-face lining plate 6c of defect, air preferentially circulates part that raw material layer 99 contacts with sidewall 6b (leaking out 1 shown in Figure 12), causes the rate of air circulation in raw material layer 99 to reduce.In addition, sealing gland bar 10, slide between the upper end because of bellows 7 wearing and tearing and grinding that produce, cause damage.Like this, air invades (leaking out 2 shown in Figure 12) from the damaged portion of sealing gland bar 10, causes the rate of air circulation in raw material layer 99 to reduce.If the rate of air circulation in raw material layer 99 reduces, then raw material layer 99 can not be made fully to sinter, therefore need to prevent it from occurring, for this reason, be the traffic attraction correspondingly increasing getter device 11 with inleakage in the past, and made up the circulation of the air in raw material layer 99.Therefore, drive the power consumption of getter device 11 to increase, cause the waste of the energy.Especially when end-face lining plate 6c inside upper part 6d is ground and produces damage, air preferentially can flow through this damaged portion, and therefore the raw material 99 of powdery flows through damaged portion, and end-face lining plate 6c inside upper part 6d is pruned because of wearing and tearing further, makes damage accelerate aggravation.Therefore, in the prior art, need before periodic maintenance, by operator by the visual degree of injury evaluating end-face lining plate 6c, when the damage of end-face lining plate 6c is serious, this pallet chassis 6 will be changed when periodic maintenance.
But, due to by the visual damage evaluating end-face lining plate 6c, make the evaluation criterion damaged not be certain because of operator.Therefore there are the following problems, when placing under repair to still spendable pallet chassis 6, increase the maintenance cost of pallet chassis 6 in vain, cause waste, on the other hand, when continuing to use end-face lining plate 6c to damage the pallet chassis 6 aggravated, the power consumption of getter device 11 is driven to increase.In addition, also existing, in order to evaluate the damage of end-face lining plate 6c, the problem of operator's action will be limited for a long time.Although describe respective chassis numbering to each pallet chassis 6, but still exist when evaluating the damage of end-face lining plate 6c, mistake checks the problem of above-mentioned chassis numbering.
Thus, as shown in patent document 1 ~ patent document 3, configure lambda sensor at bellows 7, measure and flow through oxygen concentration contained in the gas of bellows 7, propose thus to measure the technology of leaking out.And, in patent document 3, describe following content, namely, to each pallet chassis 6, installation site measurement mechanism, measures the position of pallet chassis 6, according to the positional information of the oxygen concentration measurements obtained by lambda sensor and pallet chassis 6, determine the pallet chassis 6 leaked out.But, in patent document 3, not open particularly, which kind of method to measure the position of pallet chassis 6 with, and determine the pallet chassis 6 that leaks out.
