Description

Technical Field

[0001] The present application relates to the field of industrial control technology, and in particular to a method for stabilizing the thickness of a ring cooler material and related equipment. Background Art

[0002] At present, in the sintering production process, the mixed material after the mixer is pelletized and granulated is consolidated into blocks on the sintering machine trolley, and the sintered ore after being crushed by the single roller crusher at the tail of the sintering machine is distributed on the ring cooler trolley. The stability of the feeding thickness of the ring cooler trolley directly affects the cooling effect of the sintered ore, the stability of the sintered ore quality and the stability of the sintering production.

[0003] However, the material thickness control of the ring cooler is mostly to adjust the speed of the ring cooler according to the material thickness observed by the image acquisition instrument at the end of the ring cooler. In actual production applications, when the sintering material is relatively large or the material thickness of the sintering machine trolley fluctuates, the material thickness of the ring cooler trolley fluctuates, which brings difficulties to the cooling temperature control of the sintered ore. The sintered ore is often overcooled or red blocks appear. The material thickness of the ring cooler is too low, resulting in the deterioration of the average particle size of the sintered ore. Sometimes, due to unreasonable material thickness control of the ring cooler, the sintering machine tailing ore bin is full of sintered ore and the top single roller crusher causes equipment failure. In order to make full use of the waste heat of the ring cooler, the thick material layer of the ring cooler will become the development direction of later production operations. Therefore, the stable control of the material thickness of the ring cooler affects the cooling effect of the sintered ore, the stable control of the quality of the sintered ore, and is also related to the stability of production and equipment and the reduction of energy consumption. At present, there is no appropriate method to solve the above problems. Therefore, it is necessary to propose a stable adjustment method for the material thickness of the ring cooler to at least solve some of the above problems. Summary of the invention

[0019] In one embodiment of the present invention, the step of controlling the material thickness of the ring cooler according to the comparison result further includes:

[0020] When the comparison result is that the material thickness of the trolley is greater than the target material thickness and the comparison result is that the actual cold burning ratio and the target cold burning ratio are inconsistent, the speed of the ring cooler is adjusted until the actual cold burning ratio and the target cold burning ratio are consistent and the high-temperature level scanner detects the material level lower than the upper limit value of the target material thickness.

[0021] In one embodiment of the present invention, the step of correcting the preset cold burning ratio according to the comparison result to obtain the target cold burning ratio further includes:

[0022] Obtain the sintering ore material level status;

[0023] When the sintered ore material level is in a high material level state, the preset cold burning ratio is increased by a third preset threshold value to obtain the target cold burning ratio.

[0024] In one embodiment of the present invention, the step of controlling the material thickness of the ring cooler according to the comparison result further includes:

[0025] When the comparison result shows that the actual cold burning ratio is inconsistent with the target cold burning ratio, the speed of the ring cooler is adjusted until the actual cold burning ratio is consistent with the target cold burning ratio and the high-temperature level scanner does not detect sintered ore.

The term "more than two" includes two or more than two situations.

[0040] See also Figure 1 , which is a schematic diagram of a process for stabilizing the thickness of a ring cooler provided in an embodiment of the present application, and may specifically include:

[0041] S110, obtaining the ring cooler speed, the sintering machine speed and the target cooling-sintering ratio;

[0042] Exemplarily, the ring cooler speed detection device and the sintering machine speed detection device respectively collect the ring cooler speed V1 and the sintering machine speed V2 in real time, and send them to the central controller through the data acquisition unit. Parameters are set in the central controller, and the parameters include: cold burning ratio, cold burning ratio upper limit, cold burning ratio lower limit, cold burning ratio adjustment amount, high temperature level scanner target material thickness upper limit, high temperature level scanner target material thickness lower limit, etc.

[0043] S120, calculating according to the speed of the ring cooler and the speed of the sintering machine to obtain an actual cooling and sintering ratio;

[0044] Exemplarily, the central controller receives the ring cooler speed V1 and the sintering machine speed V2, and calculates the actual cold firing ratio K1 according to the ring cooler speed V1 and the sintering machine speed V2, wherein the actual cold firing ratio = ring cooler speed / sintering machine speed; when the central controller receives that the ring cooler is stopped (V1 = 0 m / min), the sintering machine is also shut down (V2 = 0 m / min); when the central controller receives that the sintering machine is stopped (V2 = 0 m / min), the ring cooler is also shut down (V1 = 0 m / min).

[0045] S130, comparing the actual cold burning ratio with the target cold burning ratio to obtain a comparison result;

[0046] Exemplarily, the control system compares the actual cold burning ratio with the target cold burning ratio. When the actual cold burning ratio K1 is consistent with the target cold burning ratio K, the speed of the ring cooler is not adjusted. When the actual cold burning ratio K1 is inconsistent with the target cold burning ratio K, the speed of the ring cooler is adjusted until the actual cold burning ratio is consistent with the target cold burning ratio, so as to achieve control of the material thickness of the ring cooler.

[0047] S140, controlling the material thickness of the ring cooler according to the comparison result.

[0048] For example, based on the comparison result, reasonable control of the material thickness of the ring cooler is achieved by adjusting the feed speed, the operating parameters of the ring cooler (such as the rotation speed, etc.), etc., so as to meet the production process requirements, improve production efficiency, ensure stable operation of the equipment, etc.

[0049] In summary, the stable adjustment method of the material thickness of the ring cooler proposed in the embodiment of the present application realizes stable control of the material thickness of the ring cooler by adjusting the actual cooling ratio. This method adjusts the fluctuation of the material thickness of the ring cooler quickly and has good stability of the material surface of the trolley. It is beneficial to improve the uniformity of cooling of sintered ore on the ring cooler, improve the quality of sintered ore, and is beneficial to the stability of sintering production and equipment. The speed of the ring cooler is adjusted only when the material thickness of the ring cooler exceeds the set upper and lower limits of the material thickness, or when the material level in the tailing bin of the sintering machine is high, thereby avoiding the fluctuation of the real-time material thickness caused by the frequent adjustment of the speed of the ring cooler in the prior art. The adjustment lag time is greatly shortened.

[0050] In some examples, the step of obtaining the ring cooler speed, the sintering machine speed and the target cooling and sintering ratio includes:

[0051] Get the material thickness of the trolley and the preset cold-burning ratio;

[0052] Comparing the material thickness of the pallet with the target material thickness to obtain a comparison result;

[0053] The preset cold-burning ratio is corrected according to the comparison result to obtain a target cold-burning ratio.

[0054] For example, the high-temperature level scanner A is installed above the annular cooler through a bracket, and the real-time acquisition of the height of the material surface in the annular cooler is used to reflect the material thickness of the trolley, so that the accumulation of materials in the annular cooler can be known at any time, and the lateral area of ​​the trolley can be fully covered. The trolley material thickness is compared with the target material thickness to obtain a comparison result. After the comparison result of the trolley material thickness and the target material thickness is obtained, if the comparison result is that the actual material thickness is inconsistent with the target material thickness, it is necessary to adjust the preset cold burning ratio according to this comparison result to obtain the target cold burning ratio.

[0055] In some examples, the step of correcting the preset cold burning ratio according to the comparison result to obtain a target cold burning ratio includes:

[0056] When the comparison result shows that the material thickness of the trolley is less than the target material thickness, the preset cold burning ratio is reduced by a first preset threshold value to obtain the target cold burning ratio;

[0057] When the comparison result is that the material thickness of the trolley is greater than the target material thickness, the preset cold burning ratio is increased by a second preset threshold value to obtain the target cold burning ratio.

[0058] Exemplarily, when the material thickness of the trolley detected by the high-temperature level scanner on the ring cooler is lower than the set target material thickness, the control system automatically corrects the preset cold burning ratio and reduces the preset cold burning ratio by the first preset threshold, that is, reduces the preset cold burning ratio by 0.02 to obtain the target cold burning ratio. When the material thickness of the trolley detected by the high-temperature level scanner on the ring cooler is higher than the set target material thickness, the control system automatically corrects the preset cold burning ratio and increases the preset cold burning ratio by 0.02 to obtain the target cold burning ratio.

[0059] In some examples, the step of controlling the material thickness of the ring cooler according to the comparison result includes:

[0060] When the comparison result is that the material thickness of the trolley is less than the target material thickness and the comparison result is that the actual cold burning ratio and the target cold burning ratio are inconsistent, the speed of the ring cooler is adjusted until the actual cold burning ratio and the target cold burning ratio are consistent and the material level detected by the high-temperature level scanner reaches the lower limit value of the target material thickness.

[0061] Exemplarily, when the material thickness of the trolley detected by the high-temperature level scanner on the ring cooler is lower than the set target material thickness, the control system automatically corrects the preset cold burning ratio, reduces the preset cold burning ratio by 0.02, and obtains the target cold burning ratio. The control system automatically adjusts the speed of the ring cooler and compares the actual cold burning ratio with the target cold burning ratio until the actual cold burning ratio is consistent with the target cold burning ratio. Repeat the above steps until the material level detected by the high-temperature level scanner reaches the lower limit of the target material thickness. Specifically: When the actual cold burning ratio K1 is less than the target cold burning ratio K, the control system automatically calculates the ring cooler speed adjustment amount △V, where △V=(K-K1)*V1 / K1. By increasing the speed △V of the ring cooler, the actual cold burning ratio is consistent with the target cold burning ratio. When the actual cold burning ratio K1 is greater than the target cold burning ratio K, the control system automatically calculates the ring cooler speed adjustment amount △V, where △V=(K1-K)*V1 / K1. By lowering the speed of the ring cooler △V, the actual cooling ratio can be made consistent with the target cooling ratio.

[0062] When the trolley material thickness H1 detected by the high-temperature level scanner on the annular cooler is less than the set lower limit of the material thickness, the control system automatically corrects the preset cooling ratio K and reduces the preset cooling ratio by 0.02 to obtain the target cooling ratio. The control system automatically calculates the annular cooler speed adjustment amount △V, where △V=0.02V1 / K1. The control system automatically lowers the annular cooler speed △V. After 6 minutes, if the trolley material thickness H1 detected by the high-temperature level scanner on the annular cooler is still lower than the set lower limit of the material thickness, repeat the above operation until the trolley material thickness H1 detected by the high-temperature level scanner is greater than the set lower limit of the material thickness.

[0063] In some examples, the step of controlling the material thickness of the ring cooler according to the comparison result further includes:

[0064] When the comparison result is that the material thickness of the trolley is greater than the target material thickness and the comparison result is that the actual cold burning ratio and the target cold burning ratio are inconsistent, the speed of the ring cooler is adjusted until the actual cold burning ratio and the target cold burning ratio are consistent and the high-temperature level scanner detects the material level lower than the upper limit value of the target material thickness.

[0065] Exemplarily, when the material thickness of the trolley detected by the high-temperature level scanner on the ring cooler is higher than the set target material thickness, the control system automatically corrects the preset cold burning ratio, increases the preset cold burning ratio by 0.02, to obtain the target cold burning ratio, and the control system automatically adjusts the speed of the ring cooler and compares the actual cold burning ratio with the target cold burning ratio until the actual cold burning ratio is consistent with the target cold burning ratio, and repeats the above steps until the material level detected by the high-temperature level scanner is lower than the upper limit of the target material thickness. Specifically: when the material thickness H1 of the trolley detected by the high-temperature level scanner on the ring cooler is greater than the set upper limit of the material thickness, the control system automatically corrects the target cold burning ratio K, increases the target cold burning ratio by 0.02, and the control system automatically calculates the speed adjustment amount △V of the ring cooler, where △V=0.02V1 / K1, and the control system automatically increases the speed of the ring cooler △V. After 6 minutes, if the material thickness H1 of the trolley detected by the high-temperature level scanner on the ring cooler is still greater than the set upper limit of the material thickness, repeat the above operation until the material thickness H1 of the trolley detected by the high-temperature level scanner is less than the set upper limit of the material thickness.

[0066] In some examples, the step of correcting the preset cold burning ratio according to the comparison result to obtain a target cold burning ratio further includes:

[0067] Obtain the sintering ore material level status;

[0068] When the sintered ore material level is in a high material level state, the preset cold burning ratio is increased by a third preset threshold value to obtain the target cold burning ratio.

[0069] Exemplarily, when the high-temperature level detection device installed at the upper part of the feeding port of the ring cooler at the lower part of the tailings bin of the sintering machine detects that the sintering ore level is in a high level state, the control system automatically corrects the preset cold burning ratio and increases the preset cold burning ratio by 0.03 to obtain the target cold burning ratio. The high-temperature level detection device is installed in the material warehouse between the upper part of the feeding port of the ring cooler and the lower part of the tailings bin of the sintering machine. When the sintering ore in the material warehouse accumulates or the material warehouse is not unloaded due to the low cold burning ratio, the high material level signal is transmitted to the central controller, and displayed and alarmed in the centralized control room.

[0070] In some examples, the step of controlling the material thickness of the ring cooler according to the comparison result further includes:

[0071] When the comparison result shows that the actual cold burning ratio is inconsistent with the target cold burning ratio, the speed of the ring cooler is adjusted until the actual cold burning ratio is consistent with the target cold burning ratio and the high-temperature level scanner does not detect sintered ore.

[0072] Exemplarily, when the comparison result shows that the actual cold burning ratio and the target cold burning ratio are inconsistent, the control system automatically adjusts the speed of the ring cooler and compares the actual cold burning ratio with the target cold burning ratio until the actual cold burning ratio is consistent with the target cold burning ratio, and repeats the above steps until the high-temperature level detection device cannot detect the sintered ore. Specifically: the control system automatically calculates the ring cooler speed adjustment amount △V, where △V = 0.03V1 / K1, and the control system automatically increases the ring cooler speed △V. After 6 minutes, if the high-temperature level detection device still detects a high material level signal, the high material level signal is transmitted to the central controller, and displayed in the centralized control room with an alarm prompt, and the above operation is repeated until the high-temperature level detection device cannot detect a high material level signal.

[0073] The present invention provides a method for stable adjustment of the material thickness of a ring cooler, which relies on the real-time analysis of the monitoring data of a high-temperature level scanner and a high-temperature level detection device by the control center, and the adjustment of the cooling-burning ratio to achieve stable control of the material thickness of the ring cooler. The method can quickly adjust the fluctuation of the material thickness of the ring cooler, and the material surface stability of the trolley is good. The adoption of this method is conducive to improving the uniformity of cooling of sintered ore on the ring cooler, improving the quality of sintered ore, and facilitating the stability of sintering production and equipment. The material thickness of the ring cooler of the present application is highly stable. The speed of the ring cooler is adjusted only when the material thickness of the ring cooler exceeds the set upper and lower limits of the material thickness, or when a high material level appears in the tailing ore bin of the sintering machine, thereby avoiding the fluctuation of the real-time material thickness caused by the frequent adjustment of the speed of the ring cooler in the prior art. The adjustment lag time of the present application is greatly shortened. The time interval from the discovery of the fluctuation of the material thickness of the ring cooler to the adjustment is less than 10 minutes.

[0074] like Figure 2As shown, the present application proposes a stable adjustment system for material thickness of annular cooler, the system comprising: a data acquisition module 21, a calculation module 22 and a comparison module 23;

[0075] The data acquisition module 21 is configured to: acquire the speed of the ring cooler, the speed of the sintering machine and the target cooling-sintering ratio;

[0077] The comparison module 23 is configured to: compare the actual cold burning ratio with the target cold burning ratio to obtain a comparison result; and control the material thickness of the ring cooler according to the comparison result.
