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, by crossbeam is arranged at the discharge of round roller batcher 1
Default measurement position, across the top of material distributing machine 2.
Multiple baffle plates 13 are suspended on the lower section of crossbeam, and each baffle plate 13 is rotated with crossbeam and is connected.Each baffle plate 13
It is respectively corresponding with a region at the discharge of round roller batcher 1.In one embodiment of the disclosure, round roller is given
The region corresponding with baffle plate 13 at the discharge of material machine 1, is the projection of the baffle plate 13 at the discharge of round roller batcher 1
Region, the width in the region is identical with the width of baffle plate 13.In the subsequent embodiment of the disclosure, existed with baffle plate 13
View field at the discharge of round roller batcher 1, is used as region corresponding with baffle plate 13 at the discharge of round roller batcher 1.
Certainly, region corresponding with baffle plate 13 at the discharge of round roller batcher 1 can also have other set-up modes, the present embodiment
In do not limit specifically.
Each baffle plate 13 can discharge the promotion lower swing of material at the discharge of round roller batcher 1 in corresponding region.
For example, certain baffle plate 13 is corresponding with certain region at the discharge of round roller batcher 1, the material energy that the corresponding region is discharged
The baffle plate 13 is enough promoted, the baffle plate 13 is swung.Similarly, discharge of each baffle plate 13 in round roller batcher 1
Locate all to that there should be a region, so that, each baffle plate 13 can discharge the promotion lower swing of material in corresponding region.
By taking a baffle plate 13 as an example, the baffle plate 13 is suspended on below the crossbeam, and plate face is towards at the discharge of round roller batcher 1.
In one embodiment of the disclosure, when not discharging material at the discharge of round roller batcher 1, baffle plate 13 is in Action of Gravity Field
Under straight down, each baffle plate 13 straight down when the distance between lower end and round roller batcher 1 be equal to preset value.This is pre-
If value is a less numerical value, such as 5 millimeters, discharge that thickness no matter is all higher than the preset value at discharge under normal circumstances.
When discharging material at the discharge of round roller batcher 1, the material of discharge is contacted with the plate face of baffle plate 13, to baffle plate
13 apply thrust, are connected because baffle plate 13 is rotated with crossbeam, therefore, baffle plate 13 can be put under the promotion of material
It is dynamic.
In one embodiment of the disclosure, each baffle plate 13 region corresponding with the discharge of round roller batcher 1,
It is related all to being used to adjust one or more fine setting gates of the load of round roller batcher 1 in sintering machine, each finely tune gate
The inventory that relevant range is discharged at the discharge of round roller batcher 1 can be adjusted.
When the load of different zones is variant at the discharge of round roller batcher 1, the corresponding quilt of baffle plate 13 in these regions
The angle that material is rotated when promoting is also inevitable different, so that, the angle rotated according to each baffle plate 13, it is possible to use the bed of material
Thickness calculator 12 obtains the material discharged in region corresponding with each baffle plate 13 at the discharge of round roller batcher 1
It is transferred to the thickness that the bed of material is formed on sintering pallet 3.
The size of baffle plate 13 has one to be fixed the normal discharge of material, and the accuracy of the testing result finally obtained
Ring.When material is outwards discharged at discharge, baffle plate 13 is first passed around, if baffle plate 13 is oversized, weight also can be compared with
Greatly, the thrust that baffle plate 13 is produced is possible to be not enough to smoothly to promote baffle plate 13 when material is outwards discharged, so that obstruction
The normal discharge of material, even results in material and is accumulated at discharge.In the case, the testing result finally obtained
Accuracy is relatively low.If baffle plate 13 is undersized, the contact area of baffle plate 13 and material is too small, largely at discharge
The material outwards discharged is likely to discharge from the both sides of baffle plate 13, cause final testing result can not represent round roller to
The material transferring discharged at the discharge of material machine 1 in the region corresponding with baffle plate 13 is to forming the bed of material on sintering pallet 3
Thickness.
In one embodiment of the disclosure, the region corresponding with baffle plate 13 is baffle plate at the discharge of round roller batcher 1
13 are in view field thereon, the design principle of baffle plate 13：For each baffle plate 13, the row of round roller batcher 1
The material discharged at material in the region corresponding with baffle plate 13 must be in contact with the plate face of baffle plate 13, it is ensured that corresponding region
The material of middle discharge can promote baffle plate 13 and all the plate face with baffle plate 13 is in contact.
In one embodiment of the disclosure, because the fine setting gate of sintering machine can be adjusted at the discharge of round roller batcher 1
The inventory of material is discharged, therefore, is gone out at the discharge to obtain round roller batcher 1 by fine setting control gate region domain
Doses, the setting of the size of baffle plate 13 can use following manner：The width of gate is finely tuned in 600 millimeters to 800 millimeters models
When enclosing interior, the width of baffle plate 13 can be in the range of 300 millimeters to 500 millimeters, and the length of baffle plate 13 can be 300
Millimeter is 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 13 is for a long time and thing
Material contact, therefore, baffle plate 13 should use corrosion-resistant, anti abrasive material.
There is predetermined interval distance between two neighboring baffle plate 13, all baffle plates 13 is evenly arranged in round roller feed
By at the discharge of machine 1, arranged so as to finally obtain multiple regions at the discharge of round roller batcher 1 with predetermined interval distance
Go out the thickness that material forms the bed of material on sintering pallet 3.There are multiple regions of predetermined interval distance using these, it is real
Uniform sampling at the discharge of present round roller batcher 1, and then can be inferred that and arranged at the discharge of whole round roller batcher 1
The material gone out forms the thickness of the bed of material on sintering pallet 3.
In one embodiment of the disclosure, multiple axles 122, multiple axles 122 and multiple baffle plates are provided with crossbeam 11
13 correspond.The axle sleeve 123 that be connected can be rotated with axle 122 by being provided with each baffle plate 13, each baffle plate 13 and
Crossbeam 11 is rotated by the axle 122 and axle sleeve 123 that match and connected.
As shown in figure 4, by taking one group of corresponding axle 122 and axle sleeve 123 as an example, axle 122 is a circular cylinder, it is fixed
The axle sleeve 123 being connected on below the crossbeam, baffle plate 13 is hook, is articulated on axle 122, can be with axle 122
For axis rotation, when baffle plate 13 is promoted by material, baffle plate 13 drives axle sleeve 123 to be rotated around corresponding axle 122.
In the disclosed embodiments, axle 122 can also be fixedly connected by miscellaneous part with crossbeam 11.Also, in the disclosure
In other embodiment, axle 122 and axle sleeve 123 can be diversified forms, and every kind of form can realize baffle plate 13 and crossbeam
11 rotation connection.
Generally, the discharge of round roller batcher 1 be in the unit interval discharge inventory it is bigger, baffle plate 13 is pushed away
Swing angle when dynamic is bigger；The inventory that the discharge of round roller batcher 1 is in unit interval discharge is smaller, baffle plate 13
Swing angle when being promoted is smaller.Based on above-mentioned thinking, it can be inferred that, when the swing angle of baffle plate 13 is larger, circle
It is larger that the discharge of roller batcher 1 is in the inventory that the unit interval discharges, when the swing angle of baffle plate 13 is smaller,
It is smaller that the discharge of round roller batcher 1 is in the inventory that the unit interval discharges.
As shown in figure 5, region corresponding with each baffle plate 13 at the discharge of round roller batcher 1, all respectively with sintering
One section on machine trolley 3 in transverse width is corresponding, i.e. relative with each baffle plate 13 by the discharge of round roller batcher 1
The material that the region answered is discharged, the scope that all corresponding one section is covered in transverse width on sintering pallet 3 respectively
Inside it is transmitted.Such as, region A is corresponded on sintering pallet 3 in transverse width at the discharge of round roller batcher 1 in Fig. 5
Line segment b at line segment a, the discharge of round roller batcher 1 on region B correspondences sintering pallet 3 in transverse width, round roller is given
Line segment c at the discharge of material machine 1 on region C correspondences sintering pallet 3 in transverse width.The material discharged in the A of region
Line segment a on sintering pallet 3 in transverse width is transmitted in the range of covering, and region B and region C are discharged
Material respectively in the range of line segment b is covered and line segment c cover in the range of be transmitted.
Because the discharge of round roller batcher 1 is in the size of unit interval discharge inventory, directly determines that material passes through cloth
Material machine 2 is transferred to after sintering pallet 3, the thickness of feed layer of material on sintering pallet 3.And the angle that baffle plate 13 is rotated
It is closely related that degree and the discharge of round roller batcher 1 are in the inventory that the unit interval discharges, and therefore, passes through and obtains gear
The swing angle of plate 13, the material by baffle plate 13 just can be known indirectly, so that, obtain the discharge of round roller batcher 1
Thickness of the material transferring discharged in the place region corresponding with each baffle plate 13 to the formation bed of material on sintering pallet 3.
Therefore, in the disclosed embodiments, the swing angle of each baffle plate 13 is measured using angel measuring instrument 14.Often
Individual angel measuring instrument 14 is corresponded with a baffle plate 13, and each angel measuring instrument 14 is connected with corresponding baffle plate 13
Connect, the swing angle for measuring corresponding baffle plate 13.
In one embodiment of the disclosure, each angel measuring instrument 14 is connected with the axle sleeve 123 on corresponding baffle plate 13,
When axle sleeve 123 rotates with baffle plate 13 relative to axle 122, angel measuring instrument 14, which can be measured, obtains axle 122
Relative rotation angle between corresponding axle sleeve 123, and the relative rotation angle, it is consistent with the swing angle of baffle plate 13.
Therefore, the relative rotation angle obtained measured by each angel measuring instrument 14 is the swing angle of corresponding baffle plate 13,
Swing angle of the angle as baffle plate 13 will be relatively rotated.
For example, angel measuring instrument 14 can be angular transducer, angular transducer is arranged on the axle sleeve 123 on baffle plate 13
On, when axle sleeve 123 rotates with baffle plate 13, angular transducer can direct measurement obtain axle sleeve 123 and axle 122
Between relative rotation angle.
Again for example, angel measuring instrument 14 can also be rotary encoder, rotary encoder is also referred to as shaft encoder, be by
Rotation position or rotation amount are converted into the electromechanical equipment of analog or digital signal, can be connected with axle sleeve 123.The rotation
Encoder results in digital pulse signal, and digit pulse is believed when axle sleeve 123 rotates relative to axle 122
Number be converted to the relative rotation angle between axle sleeve 123 and axle 122.
Due to sintering live many corrosive gas, many dust, many dirt and wet gas are easily caused angel measuring instrument 14 and occurred
Damage, cause the measurement result of angel measuring instrument 14 inaccurate or even can not normally measure.Therefore, in the another of the disclosure
In individual embodiment, be respectively arranged with outside each angel measuring instrument 14 one angel measuring instrument 14 can be sealed every
From cover, angel measuring instrument 14 and external environment condition can be isolated by the cage, and then, it is to avoid angel measuring instrument 14 by
To the influence of external environment, occurs the inaccurate situation of measurement result, also, be also capable of making for extending angle measuring instrument 14
Use the life-span.
