Accompanying drawing in example, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described reality
It is only a part of embodiment of the invention to apply example, rather than whole embodiments.Based on the embodiment in the present invention, ability
The every other embodiment that domain those of ordinary skill is obtained under the premise of creative work is not made, should all belong to this
Invent the scope of protection.
As shown in figure 1, sintering machine is in normal working condition, material is discharged at the discharge of batcher 1, is dropped
In material distributing machine 2, and transmitted by material distributing machine 2 to sintering pallet 3.
A kind of thickness of feed layer detection means that Fig. 2 provides for the embodiment of the present disclosure, transmitted on sintering pallet 3 for being detected
Material thickness of feed layer.As shown in Figures 2 and 3, the detection means includes fixed support 11, thickness of feed layer calculator
12 and multigroup Weight detecting device 13.
Fixed support 11 is the support frame of whole detection means, the fixed support 11 be in door type structure, including support bar and
Crossbeam, wherein, support bar is fixed on the both sides of sintering pallet 3, and crossbeam is arranged on pre- by the discharge of batcher 1
If measurement position, across the top of material distributing machine 2.
As shown in Figures 2 and 3, each group of Weight detecting device 13 includes a weight sensing instrument 131 being arranged on crossbeam
With a baffle plate 132 weighed on face for being fixed on weight sensing instrument 131, weight sensing instrument 131 and baffle plate 132 mounted thereto
Correspond.Wherein, weight sensing instrument 131 can be weighing sensor, can measure the object that is placed on its check weighing face
Weight.
In embodiment of the disclosure, each weight sensing instrument 131 can be directly fixedly mounted on crossbeam, for example, horizontal
Multiple mounting grooves are provided with beam, each weight sensing instrument 131 is fixed in mounting groove.Or, each weight sensing instrument 131 is also
It can be fixedly mounted on by an independent support member on crossbeam, for example, support member can be column stock, support member
One end be fixedly connected weight sensing instrument 131, the other end is fixed and is inlaid into inside crossbeam, by support member make weight sensing instrument 131 with
Crossbeam is fixedly connected.
Baffle plate 132 is fixed on the weighing on face of weight sensing instrument 131, when not placing other objects on baffle plate 132, check weighing
The weight that instrument 131 is measured is the weight of baffle plate 132.In one embodiment of the disclosure, by weight sensing instrument 131
Initial weight is set to 0, i.e. the initial weight of weight sensing instrument 131 has subtracted the weight of baffle plate 132, in order to which the bed of material is thick
Spend calculator 12 subsequently directly can carry out computing using the measurement data of weight sensing instrument 131.
As shown in figure 4, the plate face of baffle plate 132 is towards at the discharge of batcher 1, and have between horizontal plane default
Angle.Air line distance at the discharge of baffle plate 132 and batcher 1 corresponding thereto between region is less than pre-determined distance threshold value,
For example, straight line of the midpoint of certain baffle plate 132 with the baffle plate 132 between corresponding region midpoint at the discharge of batcher 1
Distance is less than 600 millimeters of pre-determined distance threshold value, so that region corresponding with baffle plate 132 at the discharge of batcher 1 is arranged
The material gone out can drop in the plate face of baffle plate 132.
After the material discharged at the discharge of batcher 1 drops in the plate face of baffle plate 132, due to baffle plate 132
There is default angle between plate face and horizontal plane.Therefore, by gravity and the follow-up material dropped in the plate face of baffle plate 132
Thrust influence, material be slipped to from the plate face of baffle plate 132 lower section material distributing machine 2 on.
If the default angle setting between the plate face and horizontal plane of baffle plate 132 is too small, drop in the plate face of baffle plate 132
Material is difficult to slide, in the plate face that can be deposited in baffle plate 132, influences the testing result of thickness of feed layer；The plate of baffle plate 132
If the default angle setting between face and horizontal plane is excessive, material easily rebounds after colliding the plate face of baffle plate 132,
And the weight sensing instrument 131 of the lower section of baffle plate 132 will not measure the weight of the material rebounded, the bed of material equally can be also influenceed
The testing result of thickness.Therefore, by repetition test, analysis, it is determined that the setting scope of default angle is at 20 degree~50 degree
Within, for example, 35 degree.
Each baffle plate 132 is corresponded with a region at the discharge of batcher 1.In one embodiment of the disclosure
In, the region corresponding with baffle plate 132 at the discharge of batcher 1 is the baffle plate 132 at the discharge of batcher 1
View field, the width in the region is identical with the width of baffle plate 132.In the subsequent embodiment of the disclosure, with baffle plate
132 view field at the discharge of batcher 1, as corresponding with baffle plate 132 at the discharge of round roller batcher 1
Region.Certainly, region corresponding with baffle plate 132 at the discharge of batcher 1 can also have other set-up modes, this reality
Apply in example and do not limit specifically.
In one embodiment of the disclosure, each baffle plate 132 region corresponding with the discharge of batcher 1, all with
The one or more fine setting gates for being used to adjust the load of batcher 1 in sintering machine are related, and each fine setting gate can be adjusted
Save the inventory that relevant range is discharged at the discharge of batcher 1.
When the load in different discharging regions is variant at the discharge of batcher 1, these corresponding baffle plates in discharging region
The weight of the material dropped on 132 is also inevitable different, so that, can be according to weight sensing instrument using thickness of feed layer calculator 12
The weight of material on each baffle plate 132 that 131 measurements are obtained, is obtained at the discharge of batcher 1 and each baffle plate 132
Thickness of the material transferring discharged in corresponding region to the formation bed of material on sintering pallet 3.
The accuracy of testing result of the size of baffle plate 132 on finally obtaining has certain influence.Material is outside at discharge
During discharge, baffle plate 132 is first passed around, if baffle plate 132 is oversized, the easy heap of the material dropped on baffle plate 132
Product, prevents the weight data obtained measured by weight sensing instrument 131 from truly reflecting the load at the discharge of batcher 1, causes
The accuracy of the testing result finally obtained is relatively low.If baffle plate 132 is undersized, contact of the baffle plate 132 with material
Area is too small, and the material largely outwards discharged at discharge is likely to directly drop in material distributing machine 2 from the both sides of baffle plate 132
On, and the thickness of feed layer that the material that these directly drop forms the bed of material on sintering pallet 3 can not be detected and obtain,
Therefore, cause final testing result more unilateral, it is likely that to be not enough to represent the real bed of material on sintering pallet 3 thick
Degree.
Therefore, in one embodiment of the disclosure, the region corresponding with baffle plate 132 is gear at the discharge of batcher 1
Plate 132 is in view field thereon, the design principle of baffle plate 132：For each baffle plate 132, batcher 1
The all materials that the region corresponding with baffle plate 132 is discharged at discharge all drop in the plate face of baffle plate 132.Ensure phase
The weight for the material discharged in corresponding region can be obtained by the measurement of weight sensing instrument 131 under baffle plate 132.
In one embodiment of the disclosure, because the fine setting gate of sintering machine can adjust outside at the discharge of batcher 1
The inventory of material is discharged, therefore, by the load in fine setting control gate region domain, gear at the discharge to obtain batcher 1
The setting of the size of plate 132 can use following manner：When finely tuning the width of gate in the range of 600 millimeters to 800 millimeters,
The width of baffle plate 132 can be in the range of 300 millimeters to 500 millimeters, and the length of baffle plate 132 can be at 300 millimeters extremely
In the range of 600 millimeters.
Further, since the live many corrosive gas of sintering, many dust, many dirt and wet gas, and baffle plate 132 is for a long time and thing
Material contact, therefore, baffle plate 132 should use corrosion-resistant, anti abrasive material.
There is predetermined interval distance between two neighboring baffle plate 132, all baffle plates 132 is evenly arranged in batcher
By at 1 discharge, so that, there are multiple region effluents of predetermined interval distance at the final discharge for obtaining batcher 1
Expect the thickness of the formation bed of material on sintering pallet 3.There are multiple regions of predetermined interval distance using these, realize
Uniform sampling at the discharge of batcher 1, and then can be inferred that the material discharged at the discharge of whole batcher 1 is burning
Tie the thickness that the bed of material is formed on machine trolley 3.
Generally, the discharge of batcher 1 be in the unit interval discharge inventory it is bigger, dropped on baffle plate 132
The weight of material is bigger；The inventory that the discharge of batcher 1 is in unit interval discharge is smaller, is dropped on baffle plate 132
The weight of material is smaller.Based on above-mentioned thinking, it can be inferred that, when the weight of material is larger on baffle plate 132, batcher
It is larger that 1 discharge is in the inventory that the unit interval discharges, when the weight of material is smaller on baffle plate 132, feed
It is smaller that the discharge of machine 1 is in the inventory that the unit interval discharges.
As shown in figure 5, region corresponding with each baffle plate 132 at the discharge of batcher 1, all respectively with sintering board
One section on car 3 in transverse width is corresponding, i.e. by the discharge of batcher 1 area corresponding with each baffle plate 132
The material that domain is discharged, all respectively on sintering pallet 3 in transverse width corresponding one section cover in the range of passed
It is defeated.Such as, the line segment a in Fig. 5 at the discharge of batcher 1 on region A correspondences sintering pallet 3 in transverse width, gives
Area at line segment b at the discharge of material machine 1 on region B correspondences sintering pallet 3 in transverse width, the discharge of batcher 1
Line segment c on domain C correspondence sintering pallets 3 in transverse width.The material discharged in the A of region is on sintering pallet 3
Line segment a in transverse width is transmitted in the range of covering, and the material that region B and region C are discharged is respectively in line segment
B is transmitted in the range of being covered in the range of covering with line segment c.
Because the discharge of batcher 1 is in the size of unit interval discharge inventory, directly determines that material passes through material distributing machine
2 are transferred to after sintering pallet 3, the thickness of feed layer of material on sintering pallet 3.And drop on baffle plate 132
It is closely related that the weight of material and the discharge of batcher 1 are in the inventory that the unit interval discharges, therefore, by obtaining
The weight of material on baffle plate 132 is taken, the material by baffle plate 132 just can be known indirectly, so that, obtain batcher 1
The material transferring discharged at discharge in the region corresponding with each baffle plate 132 is to forming the bed of material on sintering pallet 3
Thickness.
Therefore, in the disclosed embodiments, each baffle plate is measured using the weight sensing instrument 131 under each baffle plate 132
The weight of material on 132.Each weight sensing instrument 131 is corresponded with a baffle plate 132, each weight sensing instrument 131 and phase
Correspondence baffle plate 132 is connected, the weight for measuring material on corresponding baffle plate 132.
Due to sintering live many corrosive gas, many dust, many dirt and wet gas are easily caused weight sensing instrument 131 and are damaged,
Cause the measurement result of weight sensing instrument 131 inaccurate or even can not normally measure.Therefore, in another embodiment of the disclosure
In, a cage that weight sensing instrument 131 can be sealed, the cage are respectively arranged with outside each weight sensing instrument 131
Weight sensing instrument 131 and external environment condition can be isolated, and then, it is to avoid weight sensing instrument 131 is influenceed by external environment, hair
The incorrect situation of raw measurement result, also, can also extend the service life of weight sensing instrument 131.
Output end of the input of thickness of feed layer calculator 12 respectively with all weight sensing instruments 131 is connected, can be according to each
The weight that individual weight sensing instrument 131 is measured is calculated in region corresponding with each baffle plate 132 at the discharge of batcher 1 and discharged
Material transferring to the thickness that the bed of material is formed on sintering pallet 3.
In one embodiment of the disclosure, model unit is provided with thickness of feed layer calculator 12, model unit is used for
The weight measured according to each weight sensing instrument 131, and default Mathematical Modeling, calculate at the discharge of batcher 1 with it is each
Thickness of the material transferring discharged in the corresponding region of individual baffle plate 132 to the formation bed of material on sintering pallet 3.
This presets Mathematical Modeling：
Wherein：HbFor the bed material laid in advance on sintering pallet 3；W is that weight sensing instrument 131 measures obtained weight；ρ is
The heap density of material, is preset value；L is the width of baffle plate 132；vsThe speed of material is transmitted for sintering pallet 3；
α is the default angle between baffle plate 132 and horizontal plane；K is correction factor, is preset value.
Because the porosity of material can change, and, the reason such as said system error causes to utilize above-mentioned formula meter
Obtained thickness of feed layer result may be inaccurate, accordingly, it would be desirable to which correction factor participates in calculating.K is correction factor, is adjusted
It is constant after being determined after examination.
After above-mentioned each parameter is determined, the thickness of feed layer of sintering pallet 3 is determined substantially, need to be artificial by ruler during debugging
The mode repeatedly measured determines the actual thickness of feed layer on sintering pallet 3, then by adjusting correction factor repeatedly, makes
The result of calculation of above-mentioned formula is equal with thickness of feed layer on the sintering pallet 3 of artificial actual measurement or reaches error permission
Within scope., can be counter to push away correction factor by repeatedly measuring actual thickness of feed layer during actual adjustment correction factor, then will
Repeatedly the average value of correction factor is used as the final correction factor k for participating in calculating after adjustment.
According to above-mentioned formula, it can calculate in region corresponding with each baffle plate 132 at the discharge for obtaining batcher 1
Thickness of the material transferring of discharge to the formation bed of material on sintering pallet 3.For example, as shown in fig. 6, gear marked as A1
The region corresponding with the discharge of batcher 1 of plate 132 is a1, the material transferring that region a1 is discharged to sintering board
The thickness that the bed of material is formed on car 3 is Ha.Similarly, the baffle plate 132 marked as B1 is corresponding with the discharge of batcher 1
Region b1 in discharge material transferring to the thickness of feed layer H that the bed of material is formed on sintering pallet 3b.Gear marked as C1
The material transferring of discharge is expected to formation on sintering pallet 3 in the region c1 corresponding with the discharge of batcher 1 of plate 132
The thickness H of layerc。
At the discharge of batcher 1, the inventory that certain region both sides is discharged and the basic phase of inventory that the region is discharged
Together.Therefore, in the material transferring discharged at the discharge for obtaining batcher 1 in the region corresponding with each baffle plate 132
Formed on to sintering pallet 3 after the thickness of the bed of material, each both sides of baffle plate 132 discharge material can be inferred to indirectly and is passed
It is defeated to forming the thickness of the bed of material on sintering pallet 3, and then would know that discharging material at the discharge of whole batcher 1 passes
The defeated thickness to the formation bed of material on sintering pallet 3.
On sintering pallet 3 is obtained after the thickness of feed layer of the bed of material, by thickness of feed layer feedback of the information to batcher 1, make
Batcher 1 can control feeding coal according to thickness of feed layer information.For example, the open amount of gate is finely tuned on control batcher 1,
And then control the feeding coal of batcher 1.By controlling the feeding coal of batcher 1, control to discharge at the discharge of batcher 1
Thickness of the material transferring to the formation bed of material on sintering pallet 3.
A kind of schematic flow sheet for sintering pallet thickness of feed layer detection method that Fig. 7 provides for the embodiment of the present disclosure, is used for

In step s 102, according to the weight of the material on each baffle plate, at the discharge that batcher is calculated respectively, with
The material discharged in the corresponding region of each baffle plate, is transferred to the thickness that the bed of material is formed on sintering pallet.
After the weight of material on each baffle plate is obtained, according to the weight of the material on each baffle plate, count respectively
At the discharge for calculating batcher, the material discharged in the region corresponding with baffle plate each described is transferred to sintering pallet
