Technical staff's every other embodiment obtained without making creative work, all should belong to protection of the present invention
Range.
As shown in Figure 1, sintering machine, in normal working condition, material is discharged from the discharge of round roller batcher 1, fall
Sintering pallet 3 is transmitted in material distributing machine 2, and by material distributing machine 2.
Fig. 2 is a kind of thickness of feed layer detection device that the embodiment of the present disclosure provides, and is transmitted on sintering pallet 3 for detecting
Material thickness of feed layer.As shown in Figures 2 and 3, the detection device include fixed bracket 11, it is thickness of feed layer calculator 12, more
A baffle 13 and multiple angel measuring instruments 14.
Fixed bracket 11 is the support frame of entire detection device, which is in door type structure, including support rod and
Crossbeam, wherein support rod is fixed on the two sides of sintering pallet 3, and crossbeam is arranged in default by the discharge of round roller batcher 1
Measurement position, across the top of material distributing machine 2.
Multiple baffles 13 are suspended on the lower section of crossbeam, and each baffle 13 is rotatablely connected with crossbeam.Each baffle 13 is
It is corresponding with a region at the discharge of round roller batcher 1 respectively.In one embodiment of the present disclosure, round roller batcher 1
Discharge at region corresponding with baffle 13, be the view field of the baffle 13 at the discharge of round roller batcher 1, the region
Width and baffle 13 it is of same size.In the subsequent embodiment of the disclosure, with baffle 13 round roller batcher 1 discharge
The view field at place, as region corresponding with baffle 13 at the discharge of round roller batcher 1.Certainly, the row of round roller batcher 1
Region corresponding with baffle 13 can also have other set-up modes at material, not limit specifically in the present embodiment.
The promotion lower swing of material can be discharged in each baffle 13 at the discharge of round roller batcher 1 in corresponding region.
For example, certain baffle 13 is corresponding with certain region at the discharge of round roller batcher 1, the material which is discharged can be pushed away
The baffle 13 is moved, the baffle 13 is swung.Similarly, each baffle 13 is corresponding at the discharge of round roller batcher 1
One region, thus, each baffle 13 can be in the promotion lower swing of corresponding region material be discharged.
By taking a baffle 13 as an example, which is suspended below the crossbeam, and plate face is towards at the discharge of round roller batcher 1.
In one embodiment of the present disclosure, when material is not discharged at the discharge of round roller batcher 1, baffle 13 erects under the effect of gravity
It is straight downwards, each baffle 13 straight down when the distance between lower end and round roller batcher 1 equal to preset value.The preset value is one
A lesser numerical value, such as 5 millimeters, the thickness that material is discharged at discharge under normal conditions is all larger than the preset value.It is fed in round roller
When discharging material at the discharge of machine 1, the material of discharge is contacted with the plate face of baffle 13, applies thrust to baffle 13, due to
Baffle 13 and crossbeam are rotatablely connected, and therefore, baffle 13 can be swung under the promotion of material.
In one embodiment of the present disclosure, each baffle 13 and corresponding region at the discharge of round roller batcher 1, all
Related for adjusting one or more fine tuning gates of 1 load of round roller batcher to sintering machine, each fine tuning gate can
Enough adjust the inventory that relevant range discharges at the discharge of round roller batcher 1.
When the load of different zones is variant at the discharge of round roller batcher 1, corresponding 13 quilt of baffle in these regions
The angle that material rotates when pushing is also inevitable different, thus, according to the angle that each baffle 13 rotates, it can use thickness of feed layer
Calculator 12 obtains the material transferring of discharge in region corresponding with each baffle 13 at the discharge of round roller batcher 1 to burning
Tie the thickness that the bed of material is formed on machine trolley 3.
The size of baffle 13 is to the normal discharge of material, and the accuracy of testing result finally obtained has a fixing
It rings.When material discharges outward from discharge, baffle 13 is first passed around, if baffle 13 is oversized, weight also can be larger, material
The thrust generated when discharge to baffle 13 outward is possible to be not enough to smoothly to push baffle 13, to hinder the normal row of material
It puts, even results in material and accumulated at discharge.In the case, the accuracy of the testing result finally obtained is relatively low.
If baffle 13 is undersized, baffle 13 and the contact area of material are too small, and the material largely discharged outward from discharge very may be used
It can be discharged from the two sides of baffle 13, cause final testing result that cannot represent at the discharge of round roller batcher 1 and baffle
The thickness of the bed of material is formed on the material transferring to sintering pallet 3 being discharged in 13 corresponding regions.
In one embodiment of the present disclosure, region corresponding with baffle 13 is baffle at the discharge of round roller batcher 1
13 view field on it, the design principle of baffle 13 are as follows: be directed to each baffle 13, at the discharge of round roller batcher 1 with
The material being discharged in the corresponding region of baffle 13 must be in contact with the plate face of baffle 13, guarantee the object being discharged in corresponding region
Material can push baffle 13 and all be in contact with the plate face of baffle 13.
In one embodiment of the present disclosure, since the fine tuning gate of sintering machine can adjust the discharge of round roller batcher 1
Place discharges the inventory of material, therefore, by the discharging in fine tuning control gate region domain at the discharge to obtain round roller batcher 1
Following manner can be used in amount, the setting of the size of baffle 13: when finely tuning the width of gate within the scope of 600 millimeters to 800 millimeters,
The width of baffle 13 can be within the scope of 300 millimeters to 500 millimeters, and the length of baffle 13 can be in 300 millimeters to 600 millimeters models
In enclosing.
In addition, due to the more corrosive gas in sintering scene, more dust, more dirt and wet gas, and baffle 13 is for a long time and material
Contact, therefore, baffle 13 should use corrosion-resistant, anti abrasive material.
There is preset interval distance between two neighboring baffle 13, all baffles 13 is enable to be evenly arranged in round roller feed
By at the discharge of machine 1, to finally obtain the multiple regions effluent at the discharge of round roller batcher 1 with preset interval distance
Expect the thickness that the bed of material is formed on sintering pallet 3.Using these multiple regions with preset interval distance, realize in round roller
Uniform sampling at the discharge of batcher 1, and then can be inferred that the material being discharged at the discharge of entire round roller batcher 1 is being burnt
Tie the thickness that the bed of material is formed on machine trolley 3.
In one embodiment of the present disclosure, multiple axis 122, multiple axis 122 and multiple baffles 13 are provided on crossbeam 11
It corresponds.The axle sleeve 123 that can be rotatablely connected with axis 122 is provided on each baffle 13, each baffle 13 and crossbeam 11 are equal
It is rotatablely connected by the axis 122 and axle sleeve 123 that match.
As shown in figure 4, axis 122 is a circular cylinder by taking one group of corresponding axis 122 and axle sleeve 123 as an example, it is fixedly connected
Axle sleeve 123 in below the crossbeam, baffle 13 is hook, is articulated on axis 122, can be axis rotation with axis 122,
When baffle 13 is pushed by material, baffle 13 drives axle sleeve 123 to rotate around corresponding axis 122.In the embodiments of the present disclosure, axis
122 can also be fixedly connected by other component with crossbeam 11.Also, in the other embodiments of the disclosure, axis 122 and axle sleeve
123 can be diversified forms, and every kind of form can be realized the rotation connection of baffle 13 Yu crossbeam 11.
Under normal circumstances, the discharge of round roller batcher 1 be in the unit time discharge inventory it is bigger, baffle 13 is pushed
When swing angle it is bigger；The inventory that the discharge of round roller batcher 1 is in unit time discharge is smaller, when baffle 13 is pushed
Swing angle it is smaller.Based on above-mentioned thinking, it can be inferred that, when the swing angle of baffle 13 is larger, the row of round roller batcher 1
Material is in that the inventory that the unit time discharges is larger, when the swing angle of baffle 13 is smaller, the discharge of round roller batcher 1
It is smaller to be in the inventory that the unit time discharges.
As shown in figure 5, region corresponding with each baffle 13 at the discharge of round roller batcher 1, all respectively with sintering machine
One section on trolley 3 in transverse width is corresponding, that is, by the discharge of round roller batcher 1 area corresponding with each baffle 13
The material that domain is discharged, all respectively on sintering pallet 3 in transverse width it is corresponding one section it is covered in the range of transmitted.
Such as, region A corresponds to the line segment a on sintering pallet 3 in transverse width, round roller batcher at the discharge of round roller batcher 1 in Fig. 5
Region B corresponds to the line segment b on sintering pallet 3 in transverse width at 1 discharge, and region C is corresponding at the discharge of round roller batcher 1
Line segment c on sintering pallet 3 in transverse width.Line of the material being discharged in the A of region on sintering pallet 3 in transverse width
Section a is transmitted in the range of covering, and the material that region B and region C are discharged is respectively in the range of line segment b is covered and line
Section c is transmitted in the range of covering.
Since the discharge of round roller batcher 1 is in the size of unit time 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 angle and circle that baffle 13 rotates
It is closely related that the discharge of roller batcher 1 is in the inventory that the unit time discharges, and therefore, passes through the swing for obtaining baffle 13
Angle can know the material by baffle 13 indirectly, thus, obtain round roller batcher 1 discharge at each baffle 13
The thickness of the bed of material is formed on the material transferring to sintering pallet 3 being discharged in corresponding region.
Therefore, in the embodiments of the present disclosure, the swing angle of each baffle 13 is measured using angel measuring instrument 14.Each
Angel measuring instrument 14 is corresponded with a baffle 13, and each angel measuring instrument 14 is connected with corresponding baffle 13, is used for
Measure the swing angle of corresponding baffle 13.
In one embodiment of the present disclosure, each angel measuring instrument 14 is connected with the axle sleeve 123 on corresponding baffle 13,
When axle sleeve 123 rotates with baffle 13 relative to axis 122, angel measuring instrument 14 can be measured to obtain axis 122 and be corresponded to
Axle sleeve 123 between relative rotation angle, and the relative rotation angle is consistent with the swing angle of baffle 13.Therefore, each
The relative rotation angle obtained measured by a angel measuring instrument 14 is the swing angle of corresponding baffle 13, will relatively rotate angle
Spend the swing angle as baffle 13.
For example, angel measuring instrument 14 can be angular transducer, angular transducer is mounted on the axle sleeve 123 on baffle 13
On, when axle sleeve 123 rotates with baffle 13, angular transducer can directly measure to obtain between axle sleeve 123 and axis 122
Relatively rotate angle.
In another example angel measuring instrument 14 or rotary encoder, it is that will revolve that rotary encoder, which is also referred to as shaft encoder,
Indexing is set or rotation amount is converted into the electromechanical equipment of analog or digital signal, can be connected with axle sleeve 123.The rotary encoder
When axle sleeve 123 rotates relative to axis 122, digital pulse signal can be obtained, and digital pulse signal is converted into axis
Relative rotation angle between set 123 and axis 122.
Due to the more corrosive gas in sintering scene, more dust, more dirt and wet gas are easy to cause angel measuring instrument 14 to damage
It is bad, cause the measurement result inaccuracy of angel measuring instrument 14 even can not normally measure.Therefore, in another implementation of the disclosure
In example, the isolation cover that angel measuring instrument 14 can be sealed is respectively arranged with outside each angel measuring instrument 14, it should be every
Angel measuring instrument 14 can be isolated from cover with external environment, in turn, avoid angel measuring instrument 14 by the shadow of external environment
It rings, there is a situation where measurement result inaccuracy, also, are also able to extend the service life of angel measuring instrument 14.
The input terminal of thickness of feed layer calculator 12 is connect with the output end of all angel measuring instruments 14, can be according to each
The thickness of feed layer of the material transmitted on the angle calculation sintering pallet 3 that angel measuring instrument 14 measures.
In one embodiment of the present disclosure, be provided with model unit in thickness of feed layer calculator 12, model unit according to
The angle of each angel measuring instrument 14 measurement, calculates area corresponding with each baffle 13 at the discharge of round roller batcher 1
