Description

Technical Field

[0001] The present application belongs to the field of steel technology, and specifically relates to a fuel crushing particle size control system and method. Background Art

[0002] In steel production, the finished product of sintering is called sintered ore. As the main raw material for blast furnace ironmaking, sintered ore directly affects the quality of blast furnace ironmaking. During the sintering process, the heat provided by the combustion of solid fuel in the mixture accounts for about 90% of the total heat required for sintering. As an important indicator of sintering production, solid fuel consumption not only reflects the level of production technology but also directly affects production costs.

[0003] The particle size of solid fuel has an important influence on the sintering process. The particle size requirement of sintering production for fuel is generally 1-3mm. If the particle size is too large, the combustion speed will be slow, the combustion zone will be widened, the maximum sintering temperature will be reduced, the air permeability of the sintering process will be poor, the vertical sintering speed will be reduced, and the sintering utilization coefficient will be reduced. At the same time, if the large particle fuel is concentrated in the lower part of the material layer due to segregation during distribution, and the automatic heat storage effect of the material layer makes the heat of the lower layer greater than that of the upper layer, it is easy to produce over-melting, which also affects the air permeability of the material layer. On the contrary, if the particle size is too small, the combustion speed will be fast, the liquid phase reaction will not be complete, the strength of the sintered ore will be poor, the yield rate will be reduced, and the utilization coefficient of the sintering machine will also be reduced. Therefore, the accurate detection and control of the particle size of sintering fuel can effectively reduce the energy consumption of the sintering process, save production costs, improve the quality of sintered ore, and increase production efficiency.

[0004] Sintering production generally uses roller crushers to crush solid fuels, such as double-roll crushers and four-roll crushers. In the prior art, the roller gap is generally adjusted manually to control the particle size of the fuel. This has poor real-time performance, long adjustment cycle, and high labor consumption, which seriously affects the precise control of the particle size of the fuel after crushing.

[0037] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0038] See also Figure 1 As shown, according to the first aspect of the present application, a fuel crushing particle size control system is provided, comprising:

[0039] A crusher 1, wherein a first crushing roller 11 and a second crushing roller 12 are arranged in the crusher 1, and a crushing gap is opened between the first crushing roller 11 and the second crushing roller 12;

[0040] A particle size visual detection unit 2, which is arranged below the crushing gap and is used to collect image information of the particle size of the crushed material;

[0041] The control unit 3 is used to receive the image information collected by the particle size visual detection unit 2 and adjust the crushing gap according to the image information.

[0042] A fuel crushing particle size control system provided in this embodiment includes a crusher 1, a particle size visual detection unit 2 and a control unit 3. A first crushing roller 11 and a second crushing roller 12 are arranged inside the crusher 1. The first crushing roller 11 and the second crushing roller 12 can crush the fuel from the crushing gap when working. The particle size visual detection unit 2 is arranged below the crushing gap to collect the particle size image information of the crushed material. The particle size visual detection unit 2 is usually composed of a high-definition camera and a lighting device. The selection of the high-definition camera should consider its resolution and frame rate to ensure that the particle size details of the crushed material can be clearly captured. The setting of the lighting equipment should ensure that sufficient light can be provided to the camera so that high-quality image information can be obtained under different environmental conditions. The installation position of the particle size visual detection unit 2 needs to ensure that the particle size image information of the crushed material can be accurately collected. For example, the camera can be installed in a direction perpendicular to the material flow so that the particle size distribution of the material can be fully observed. The control unit 3 is responsible for receiving the image information collected by the particle size visual detection unit 2 and adjusting the crushing gap according to the image information. The control unit 3 can satisfy the functions of quickly processing image information and adjusting the crushing gap between the first crushing roller 11 and the second crushing roller 12. The control unit 3 can accurately identify the particle size distribution of the material from the collected image information. The control unit 3 analyzes whether the qualified particle size ratio in the crushed material meets the standard based on the image information, and then adjusts the crushing gap between the first crushing roller 11 and the second crushing roller 12 through control. For example, if the image information shows that the qualified particle size ratio in the crushed material does not meet the standard, if the large particle size ratio exceeds the standard, the control unit 3 can issue an instruction to reduce the crushing gap to improve the crushing effect; conversely, if the large particle size ratio does not exceed the standard, the control unit 3 can increase the crushing gap to improve the crushing efficiency. Through the synergistic effect of the crusher 1, the particle size visual detection unit 2 and the control unit 3, the real-time monitoring and automatic adjustment of the fuel crushing particle size are realized, the fuel crushing cycle is shortened, and the qualified rate of the fuel particle size after crushing is higher, which is beneficial to the subsequent sintering operation, and can effectively reduce the energy consumption of solid fuel, improve the quality of sintered ore, and increase production efficiency.

[0043] The particle size visual detection unit 2 comprises:

[0044] A first image acquisition member 21, wherein the first image acquisition member 21 is disposed below the crusher 1, and the first image acquisition member 21 is located on one side of the crushed material;

[0045] The first luminous background plate 22 is arranged below the crusher 1, and the first luminous background plate 22 is arranged on the other side of the crushed material.

[0046] In this technical solution, the particle size visual detection unit 2 can accurately collect the particle size image information of the crushed material, providing a basis for the system to achieve accurate particle size control. The particle size visual detection unit 2 includes a first image acquisition component 21 and a first luminous background plate 22.

[0047] The first image acquisition component 21 is arranged below the crusher 1 and is located on one side of the crushed material. The first image acquisition component 21 usually adopts a high-definition industrial camera, and its selection needs to fully consider the actual needs of the system and the working environment. In terms of resolution, it is necessary to ensure that the details of materials of different particle sizes can be clearly captured for subsequent image analysis and processing. The choice of frame rate is also very important. For fast-flowing crushed materials, a higher frame rate is required to obtain continuous image information in real time. The installation position of the first image acquisition component 21 must ensure that it can fully cover the material flow, and avoid being affected by factors such as vibration and dust during the operation of the crusher 1. For example, a sturdy bracket and shock-absorbing device can be used to fix the first image acquisition component 21 to ensure its stability and reliability during operation.

[0048] The first luminous background plate 22 is arranged below the crusher 1 and is located on the other side of the crushed material. The function of the first luminous background plate 22 is to provide a uniform, high-contrast background for the first image acquisition component 21 so as to better highlight the outline and particle size characteristics of the material. The first luminous background plate 22 is usually made of a high-brightness LED light panel or other luminous materials, and its brightness and color can be adjusted according to actual needs. During the installation process, it is necessary to ensure that the relative position of the first luminous background plate 22 and the first image acquisition component 21 is fixed to ensure the stability and consistency of image acquisition. At the same time, the surface of the first luminous background plate 22 should be kept clean and flat to avoid reflections or shadows that affect the image quality.

[0049] The first image acquisition member 21 and the first luminous background plate 22 in the particle size visual detection unit 2 cooperate with each other to provide the fuel crushing particle size control system with accurate and reliable particle size image information of the crushed material.

[0050] The control unit 3 comprises:

[0051] An adjusting driver 31, wherein the adjusting driver 31 is disposed in the crusher 1, and the adjusting driver 31 is connected to the second crushing roller 12, and is used for adjusting the crushing gap;

[0052] The controller 32 is electrically connected to the first image acquisition component 21 and the adjustment driver 31 .

[0053] In this technical solution, the control unit 3 includes an adjustment driver 31 and a controller 32. The adjustment driver 31 is arranged in the crusher 1 and connected to the second crushing roller 12. The adjustment driver 31 is used to adjust the crushing gap. The adjustment driver 31 can be stably connected to the second crushing roller 12, and can accurately adjust the position of the crushing roller under the instruction of the controller 32. During operation, the adjustment driver 31 needs to have a fast response and high-precision adjustment capability to meet the system's requirements for real-time adjustment of the crushing gap. When the controller 32 determines that the crushing gap needs to be adjusted based on the image information provided by the particle size visual detection unit 2, the adjustment driver 31 can quickly execute the instruction, change the position of the second crushing roller 12, and thus adjust the size of the crushing gap.

[0054] The controller 32 is electrically connected to the first image acquisition component 21 and the adjustment driver 31. The controller 32 is usually composed of a high-performance microprocessor and professional control software. After receiving the image information from the first image acquisition component 21, the controller 32 uses advanced image processing algorithms and data analysis techniques to identify and analyze the material particle size in the image. By comparing with the preset particle size standard, the controller 32 determines whether the current crushing effect meets the requirements and determines whether the crushing gap needs to be adjusted. If adjustment is required, the controller 32 will send precise control instructions to the adjustment driver 31 to achieve accurate adjustment of the crushing gap.

[0055] It is understandable that the adjustment driver 31 may be an electric servo driver or a hydraulic driver, etc., to achieve precise position control and powerful driving force.

[0056] The device further comprises a displacement sensor 4 , which is connected to the second crushing roller 12 . The displacement sensor 4 is used to detect the distance between the first crushing roller 11 and the second crushing roller 12 .

[0057] In this technical solution, the fuel crushing particle size control system further includes a displacement sensor 4, which is connected to the second crushing roller 12 and can accurately measure the position change of the second crushing roller 12. The installation method of the displacement sensor 4 should ensure that the connection between it and the second crushing roller 12 is firm and reliable, and will not affect the normal operation of the crusher 1. In use, the displacement sensor 4 can accurately detect the distance between the first crushing roller 11 and the second crushing roller 12 through the relative position relationship between the position of the second crushing roller 12 and the first crushing roller 11.

[0058] The setting of the displacement sensor 4 can be used as a verification of the accuracy of the adjustment of the crushing gap by the adjustment driver 31. When the adjustment driver 31 adjusts the position of the second crushing roller 12 according to the instruction of the controller 32, the displacement sensor 4 can provide real-time feedback on the actual change of the crushing gap to ensure the accuracy of the adjustment. On the other hand, the continuous monitoring of the displacement sensor 4 can provide more accurate feedback information to the controller 32, so that the controller 32 can control the crushing gap more accurately. The displacement sensor 4 plays an important auxiliary detection role in the fuel crushing particle size control system, and works in conjunction with the adjustment driver 31 and the controller 32 to achieve accurate detection and control of the distance between the first crushing roller 11 and the second crushing roller 12.

[0059] It also includes a second image acquisition component 5, which is arranged above the crusher 1, and is used to collect the image information of the crushing gap feed. The second image acquisition component 5 is electrically connected to the controller 32.

[0060] In this technical solution, the fuel crushing particle size control system also includes a second image acquisition component 5, which is installed above the crusher 1 and can optimally collect image information of the feed in the crushing gap. The second image acquisition component 5 usually uses a high-definition industrial camera similar to the first image acquisition component 21, but may differ in parameters and installation angles to meet the needs of feed image acquisition. For example, its resolution and frame rate must be able to clearly capture the shape and distribution of the material entering the crushing gap. During the installation process, the stability and reliability of the second image acquisition component 5 must be ensured to avoid being affected by factors such as vibration and dust during the operation of the crusher 1. Special brackets and protective devices can be used to protect the second image acquisition component 5 to ensure its long-term stable operation.

[0061] The second image acquisition component 5 is electrically connected to the controller 32, and transmits the collected crushing gap feed image information to the controller 32 in real time. The controller 32 uses an image processing algorithm to analyze the feed image to determine whether abnormal conditions such as blockage occur. For example, by analyzing the characteristics of the material flow state and accumulation degree in the feed image, potential blockage risks can be discovered in time. If the controller 32 detects an abnormality in the feed image, such as excessive accumulation of materials or poor flow, it can send a signal to the control unit 3, and the control unit 3 prevents material blockage by increasing the crushing gap or reducing the feed speed.

[0062] It also includes a feeding unit 6, which is used to transport materials to the crusher 1.

[0063] In this technical solution, the fuel crushing particle size control system further includes a feeding unit 6 , which is installed above the crusher 1 and is used to provide materials to the crusher 1 .

[0064] The first image acquisition component 21 and the second image acquisition component 5 are cameras.

[0065] In this technical solution, in the fuel crushing particle size control system, the first image acquisition component 21 and the second image acquisition component 5 play a key role in image acquisition. Both are cameras, providing an important source of visual information for the system to achieve precise particle size control and feed monitoring.

[0066] The first image acquisition component 21 is a camera located below the crusher 1 and on one side of the crushed material. It plays a vital role in the system. This camera needs to have the characteristics of high resolution and high frame rate to ensure that the fine particle size characteristics and dynamic changes of the crushed material can be clearly captured. When selecting a camera, its stability and durability in an industrial environment should be considered. For example, an industrial-grade camera with waterproof, dustproof and shock-resistant functions can be selected to adapt to the harsh working environment around the crusher 1. The installation position of the camera must be accurately calculated and adjusted to ensure that the crushed material can be photographed at the best angle while avoiding the influence of vibration and material splashing during the operation of the crusher 1. In order to obtain better image quality, appropriate lighting equipment can also be equipped to enhance the contrast and clarity of the material.

[0067] The second image acquisition component 5 is arranged above the crusher 1, and is used to collect image information of the feed in the crushing gap. Also as a camera, it needs to have different characteristics from the first image acquisition component 21 to meet the needs of feed monitoring. Since the light conditions and material morphology in the feeding area are different from those in the area after crushing, this camera may need a higher dynamic range and a wider field of view so that it can fully observe the material entering the crushing gap. In terms of installation position, it is necessary to ensure that the camera can cover the entire feeding area and will not be blocked by the feeding device or other obstacles. Similar to the first image acquisition component 21, the second image acquisition component 5 also needs to have good stability and anti-interference ability to ensure that image information can be continuously and stably collected during the operation of the crusher 1.

[0068] See also Figure 1 As shown, the second aspect of the present application provides a fuel crushing particle size control method, which adopts the fuel crushing particle size control system in any embodiment of the first aspect, and includes the following steps:

[0069] S1, the control unit 3 adjusts the crushing gap;

[0070] Specifically, before the system is started, the control unit drives the second crushing roller to move by adjusting the driver, and adjusts the crushing gap between the first crushing roller and the second crushing roller to within a set range, and then the system can be started.

[0071] S2, the particle size visual detection unit 2 collects image information of the material after crushing;

[0072] Specifically, the feeding unit 6 feeds the material into the crushing gap between the first crushing roller 11 and the second crushing roller 12 in the crusher 1 to crush the material, and the crushed material is discharged from the bottom of the crusher 1. At this time, the first luminous background plate 22 in the particle size visual detection unit 2 is used to provide a uniform, high-contrast background, and the first image acquisition component 21 can film or photograph the crushed material and feed the acquired image information to the control unit 3.

[0073] S3, the control unit 3 determines whether the qualified particle size ratio of the crushed material meets the requirements;

[0074] Specifically, after receiving the image information, the control unit 3 analyzes the proportion of qualified particle sizes in the crushed material according to the image information. In this process, the comparison pattern is based on the material particle size information collected after the installation of each component and crushing, and it is used as the comparison standard.

[0075] S4. If the proportion of qualified materials after crushing does not meet the requirement, the crushing gap is adjusted by the control unit 3; if the proportion of qualified materials after crushing meets the requirement, the crushing gap feeding information is acquired by the second image acquisition component 5;

[0076] Specifically, when the system detects that the proportion of qualified materials after crushing does not meet the preset requirements, the controller 32 in the control unit 3 will respond quickly. The controller 32 first receives the image information of the crushed materials collected by the first image acquisition component 21, and compares and analyzes these images. Through image processing algorithms and pattern recognition technology, the controller 32 can accurately determine the particle size distribution of the material, and then determine whether the current crushing gap is appropriate. If the proportion of qualified materials is too low, it may mean that the crushing gap is too large, resulting in insufficient material crushing; conversely, if the proportion of qualified materials is too high but exceeds a certain range, it may be that the crushing gap is too small, causing some materials to be over-crushed. Based on these analysis results, the controller 32 sends precise control instructions to the adjustment driver 31. The adjustment driver 31 adjusts the position of the second crushing roller 12 according to the instructions, thereby changing the crushing gap between the first crushing roller 11 and the second crushing roller 12. During the adjustment process, the displacement sensor 4 monitors the changes in the crushing gap in real time and transmits feedback information to the controller 32 to ensure the accuracy and stability of the adjustment.

[0077] When the proportion of qualified materials after crushing meets the requirements, the system will detect the feeding information of the crushing gap. At this time, the second image acquisition component 5 comprehensively collects the feeding image information of the crushing gap.

[0078] S5, the control unit 3 determines whether the crushing gap feeding meets the requirements; if the crushing gap feeding does not meet the requirements, the crushing gap is adjusted by the control unit 3; if the crushing gap feeding meets the requirements, the adjustment ends.

[0079] Specifically, first, the control unit 3 judges the crushing gap feeding to determine whether it meets the requirements. The controller 32 in the control unit 3 receives the crushing gap feeding image information collected by the second image acquisition component 5 and analyzes the feeding situation.

[0080] If the feeding of the crushing gap does not meet the requirements, material blocking occurs. The controller 32 increases the crushing gap between the first crushing roller 11 and the second crushing roller 12 by adjusting the driver 31 according to the image analysis results. During the adjustment process, the displacement sensor 4 monitors the change of the crushing gap in real time and transmits feedback information to the controller 32, so that the controller 32 can accurately control the adjustment process to ensure that the crushing gap is adjusted to a suitable size to improve the feeding situation.

[0081] If the crushing gap feed meets the requirements, it means that the current feed state and crushing gap setting can ensure the stable and efficient operation of the system. At this point, the adjustment process ends, and the system continues to perform fuel crushing operations in the current state. The control unit 3 continuously monitors the proportion of qualified materials after crushing and the crushing gap feed situation, so as to make timely adjustments when necessary to ensure that the system always maintains the best operating state.

[0082] In S4, if the proportion of qualified materials in the crushed material does not meet the requirements, it is necessary to determine the proportion of large particles in the crushed material.

[0083] If the proportion of large particles in the crushed material exceeds the standard, the control unit 3 is used to adjust and reduce the crushing gap; if the proportion of large particles in the crushed material does not exceed the standard, the control unit 3 is used to adjust and increase the crushing gap.

[0084] Specifically, during the execution of the fuel crushing particle size control system, when it is determined in step S4 that the proportion of qualified materials in the crushed material does not meet the requirements, it is also necessary to determine the proportion of large particles in the crushed material.

[0085] If the proportion of large particles in the crushed material exceeds the standard, it means that the current crushing gap may be too large, resulting in insufficient material crushing and too much large particle material. At this time, the control unit 3 plays a key role in adjustment. The controller 32 in the control unit 3 receives the image information of the crushed material collected by the first image acquisition component 21, and accurately identifies the proportion of large particle materials through advanced image processing algorithms and pattern recognition technology. Once it is determined that the proportion of large particles exceeds the standard, the controller 32 sends an instruction to the adjustment driver 31 to adjust and reduce the crushing gap. The adjustment driver 31 responds to the instruction and accurately adjusts the position of the second crushing roller 12 to reduce the crushing gap between the first crushing roller 11 and the second crushing roller 12. This can increase the crushing force of the material, reduce the generation of large particle materials, and increase the proportion of qualified materials. During the adjustment process, the displacement sensor 4 monitors the changes in the crushing gap in real time, and transmits feedback information to the controller 32 to ensure the accuracy and stability of the adjustment.

[0086] If the proportion of large particles in the crushed material does not exceed the standard, the situation is different. This may indicate that the current crushing gap is too small. Although there are fewer large-particle materials, it may cause some materials to be over-crushed, affecting production efficiency and energy consumption. At this time, the control unit 3 also makes adjustments, but the direction is to increase the crushing gap. The controller 32 sends a corresponding instruction to the adjustment driver 31, and the adjustment driver 31 adjusts the position of the second crushing roller 12 to increase the crushing gap. This can reduce the situation of over-crushing, improve crushing efficiency, and ensure that the proportion of qualified materials is within a reasonable range. The displacement sensor 4 also plays an important feedback role in this process to ensure the accuracy of the adjustment.

[0087] By judging the proportion of large particles in the crushed material and adjusting the crushing gap accordingly by the control unit 3 according to the judgment result, the performance of the fuel crushing particle size control system can be effectively improved, ensuring the output of materials that meet the requirements and improving production efficiency and quality.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
