Description

Technical Field

[0001] The present invention relates to the technical field of furnace smelting, and in particular to an automated chute heat preservation and anti-coking system, method and device. Background Art

[0002] Furnace smelting, high-temperature furnace and chute are important components of metallurgy and smelting process, and each part plays a specific role in the whole smelting process. Furnace smelting is the process of extracting and processing metals or alloys in a high-temperature furnace. The high-temperature furnace is the internal space of the furnace, which is mainly used for heating and smelting materials. The chute is a channel or structure used to guide molten metal, slag or gas during the smelting process. It is usually located at the bottom or side of the furnace, which can effectively guide the smelted products to the next processing link or collect them. The chute works at the bottom of the high-temperature furnace, with a temperature of about 1000℃. The high-temperature melt can easily produce a large amount of coking on the chute, which will cause the chute to be blocked, seriously affecting the normal operation of the furnace smelting. In order to maintain the normal operation of the chute, operators are required to go to the site to observe the coking condition of the chute and use a long steel bar to poke into the chute manually to clear the coke. The chute under the furnace is in a high temperature state. Due to the unstable negative pressure inside, the high-temperature molten material may splash out at any time. Even if the operators wear protective clothing during the coking process, scalding accidents often occur. Therefore, an automated chute insulation and anti-coking system is urgently needed to replace manual coking, avoid scalding accidents caused by high temperature environments, and ensure the safe and stable operation of the chute.

[0003] Prior art 1, Chinese patent, application number: 202110617321.6 discloses an online detection device and method for FeO content in sintered ore with an inclined sleeve structure, including an electric control system, a feeding batching scale, a feeding inclined chute arranged below the feeding batching scale drop point, a magnetic induction coil and its frame sleeved on the outer wall of the middle part of the feeding inclined chute, a material level detection instrument arranged above the feeding inclined chute, and a material flow detection instrument arranged below the feeding inclined chute. The feeding inclined chute includes a No. 1 chute and a No. 2 chute corresponding to the No. 1 chute. Although the blocking state can be automatically determined, the feeding is stopped at the same time to avoid material stacking; the feeding inclined chute and the magnetic induction coil and its frame are lubricated and installed with a sleeve structure, which is convenient for extracting and reinstalling the feeding inclined chute from the magnetic induction coil and its frame. The feeding inclined chute adopts a detachable split structure, which can easily remove the blocked materials and reduce the labor intensity of maintenance personnel. However, decoking in a high-temperature environment can easily cause scalding accidents, and the efficiency of decoking mostly depends on the experience of the personnel, resulting in poor decoking results.

[0004] Prior art 2, Chinese patent, application number: 202110617320.1 discloses an online detection device and method for FeO content in sintered ore that is convenient for cleaning blockages, including an electronic control system, a feeding and batching scale, a feeding chute arranged below the drop point of the feeding and batching scale, a magnetic induction coil and its frame sleeved on the lower outer wall of the feeding chute, a material level detection instrument arranged above the feeding chute, and a material flow detection instrument arranged below the feeding chute. Although the blockage state is automatically judged and the feeding is stopped at the same time to avoid material stacking; the feeding chute and the magnetic induction coil and its frame are lubricated and installed with a sleeve structure, which is convenient for extracting and reinstalling the feeding chute from the magnetic induction coil and its frame, reducing the labor intensity of maintenance personnel; avoiding the wear of the magnetic induction coil and the frame, improving the service life of the equipment, and reducing the maintenance amount and operation cost of the measuring device. However, the coke cleaning efficiency is still not high, and it is easy to cause safety accidents.

[0005] Prior art three, Chinese patent, application number: 202311187862.5 discloses a method for determining flux residues in aluminum alloy melts, including the following steps: adding a refining agent to the aluminum melt during the smelting and refining stage of the cast aluminum alloy; wherein the smelting temperature is controlled at 720-770°C, and the refining temperature is controlled at 700-750°C; during refining, adding a refining agent and introducing an inert gas; the aluminum alloy liquid is transferred from the smelting furnace to the static furnace, and then from the static furnace to the chute, passing through the online melt purification system, and reaching the adapter sleeve at the end of the chute; in the aluminum alloy liquid casting stage, the aluminum alloy liquid flows downward through the end of the chute into the adapter sleeve; the presence of flux residues is determined by the aluminum liquid injection flow rate in the adapter sleeve. Although by pre-judging whether the flux has component residues in the early stage of production, it is finally confirmed whether the refining agent is suitable for aluminum alloy melt processing applications, which provides support and guarantee for whether different fluxes can be applied to aluminum alloy melting and casting processes. However, there is a lack of technical means to detect coking in the chute, and coke cleaning still needs to be done manually, which is not only inefficient but also easy to cause harm.

[0006] At present, the prior art 1, prior art 2 and prior art 3 have the problem that the coke clearing process is cumbersome, time-consuming and labor-intensive, and scalding accidents are prone to occur, resulting in poor safety of coke clearing work. Therefore, the present invention provides an automated chute heat preservation and anti-coking system, method and device. Summary of the invention

Nonlinear correction and comprehensive performance By constructing a performance matrix and nonlinear correction terms, the comprehensive efficiency of the analog-to-digital converter is evaluated, including consideration of the interaction of multiple variables; the system is allowed to adjust in real time according to different working conditions to improve the overall conversion efficiency. Significance achieved: The introduction of nonlinear correction terms can more truly reflect the conversion efficiency of the sensor under different working conditions and avoid the limitations of a single expected value; through a comprehensive understanding of the performance of the analog-to-digital converter, the design scheme can be optimized based on actual data.

Step S323 calculates the melt volume, combined with the extracted point cloud data, to accurately calculate the volume of the melt, which can effectively convert the three-dimensional data into quantitative volume information; completes the output of the melt volume and related three-dimensional feature data for further analysis and decision-making. Implementation significance: Accurate volume calculation provides important parameters for understanding the flow behavior of the melt, helping to formulate corresponding processes and control plans; by analyzing the change trend of the melt volume, problems in the flow can be identified early, so that preventive measures can be taken before potential failures such as coking occur.

[0157] In summary, the process of extracting the three-dimensional characteristics and volume information of the melt in this embodiment realizes accurate data acquisition, feature extraction and volume calculation, which not only provides a quantitative basis for in-depth analysis of the physical properties of the melt, but also provides important decision-making support for subsequent production process optimization, fault warning and process improvement.

[0158] Further, the process of identifying the melt part and the background in step S321 specifically includes the following steps:

[0159] Step S3211: Calculate the average coordinates of each point to generate a global center of a set of data; use the center as a reference point, and generate a transformation matrix based on the distances and angles of all points relative to the center; use the transformation matrix to perform a linear transformation on the coordinates of each data point to adjust the positions of all points in the coordinate system;

[0160] Among them, the calculation of the global center is:

[0161] Calculate the average coordinates of all points, that is:

[0162]

[0163] Where N is the total number of points, (x i ,y i ,z i ) are the coordinates of each point.

[0164] Translation transformation:

[0165] Create a translation vector (T = (-Cx, -Cy, -Cz)) to move the center of the point cloud to the origin of the coordinate system to eliminate the overall offset of the point cloud.

[0166] Rotation transformation:

[0167] Set the rotation matrix R and define the rotation around the X, Y or Z axis as needed to adjust the point cloud posture. The rotation matrix is ​​usually a 3x3 matrix and can be expressed as:

[0168]

[0169] where r ij is the coefficient calculated according to the rotation angle;

[0170] Generate the final transformation matrix: The final total transformation matrix M is usually a 4x4 homogeneous transformation matrix:

[0171]

[0172] Where (T x ,T y ,Tz ) are the components of the translation part, and the last line is used for the representation of homogeneous coordinates;

[0173] In practical applications, for each point P i =(x i ,y i ,z i ,1) T , by multiplying it with the transformation matrix M, we can get the new point coordinates P' i :

[0174] P' i =M·P i

[0175] The linear transformation of points in the coordinate system is realized, ensuring the accurate representation of the melt geometry;

[0176] Step S3212: using the spatial distribution of points, calculate the adjacency relationship between points in the point cloud data set; establish a connection map of adjacent points, establish a local neighborhood model for each point, and identify areas with higher point density; based on density analysis, based on the set threshold, remove points in sparse areas to form a preliminarily screened point cloud data set;

[0177] Step S3213: Analyze the neighborhood distribution characteristics of each remaining point in the point cloud data set excluding the initially screened ones, quantify the connectivity and spatial characteristics of the neighborhood around each point, and determine whether it meets the structural characteristics of the melt; accurately separate the qualified points from the background points; and obtain a corrected point cloud data set by screening and filtering the point cloud.

[0178] Preferably, step S3211 of this embodiment generates a global center by calculating the average coordinates of all points, which provides a benchmark for geometric correction; based on the global center, a transformation matrix is ​​created, which defines the mapping relationship from the initial coordinate system to the target coordinate system, so that all data points can be adjusted in a consistent manner; each point is subjected to a linear transformation of the coordinates by applying the transformation matrix, thereby eliminating the geometric errors generated during the scanning process. Implementation significance: By coordinating the spatial position of the point cloud data, it is ensured that the geometric features of the melt are presented in an optimized state, providing an accurate data basis for subsequent analysis; a unified coordinate standard is established for data collected from different data sources or under different conditions, so that the processing in subsequent steps is more consistent. Step S3212 analyzes the spatial relationship between each point, establishes an adjacency matrix between points, and maps the mutual connection between each point in the data set; constructs a local model for each point, identifies the high-density area from it, and ensures that the melt part can be effectively focused; according to the preset density threshold, those relatively sparse points are eliminated to form a preliminary integrated point cloud data set. Implementation significance: By eliminating points in low-density areas, the impact of background noise is significantly reduced, ensuring that subsequent data processing is concentrated on the melt part; by identifying and retaining only points with high density, the time and computing resource consumption of subsequent processing are reduced, and the efficiency of the overall process is improved. Step S3213 analyzes the neighborhood distribution characteristics of each point in the point cloud left after the initial screening, and quantifies its spatial characteristics, including connectivity, changes in local density, etc.; according to the geometric characteristics and structure of the melt, it is judged whether these points meet the morphological standards of the melt; through further screening and filtering of the data, the points that meet the shape characteristics of the melt are clearly separated from the background noise, and finally the representative points of the melt are extracted. Implementation significance: By further refining the screening and eliminating unqualified data, it is helpful to improve the quality and effectiveness of the remaining data, making the data set more representative; after clearly dividing the melt and the background, it can provide high-quality data support for subsequent three-dimensional feature extraction and volume calculation, ensuring the reliability of the analysis results and the effectiveness of business decisions.

[0179] In summary, the extraction of viscous structure and accurate identification of background in this embodiment form a complete processing chain, which ensures the data quality at each step, achieves a balance between computational efficiency and result reliability, and provides a strong foundation for further advancement of melt property analysis.

[0180] Furthermore, the process of identifying the area with higher point density in step S3212 specifically includes the following steps:

[0181] Step S32121: Select a neighborhood radius r to determine which neighboring points are included when calculating the local features of each point. The radius is based on a pre-set empirical value. For each point P in the point cloud dataset, i =(xi ,y i ,z i ), and find the points in its neighborhood as follows:

[0182] Traverse all data points P j =(x j ,y j ,z j ), calculate its intersection with point P i The Euclidean distance of:

[0183]

[0184] If d ij , then point P j Include point P i In the neighborhood of

[0185] Step S32122: for each point P i Generate a neighborhood model and use a data structure to store all points in its neighborhood; use a dictionary or hash table to implement it, with the key value pointing to point P i A reference to a point P, and the value contains a list of neighbors; for each point P i , the neighborhood model now includes its neighboring point set; calculate the point density ρ i :

[0186]

[0187] Where N i It's point P i The number of points in the neighborhood, V is the volume of the neighborhood, for a spherical neighborhood:

[0188] Step S32123: By comparing the density value ρ of each point i With the set threshold, those points that meet the conditions are marked, forming the preliminary screening results of the high-density area.

[0189] Preferably, step S32121 of this embodiment selects a neighborhood radius r and finds points in the neighborhood. By setting a neighborhood radius, the local range considered for each point in the calculation process is determined, so that the local characteristics of the point can be effectively focused on; by traversing all points and calculating the Euclidean distance, the neighborhood points of each point are identified in real time, thereby forming local structural information in the overall data set. Implementation significance: It lays the foundation for point density calculation, so that the local neighborhood of each point can be clearly defined, and the necessary spatial context is provided when analyzing the data distribution of the point cloud; according to the setting of the neighborhood radius, data sets of different densities can be flexibly analyzed, affecting the recognition effect of subsequent high-density areas, making the processing more efficient. Step S32122 generates a neighborhood model and calculates the point density, generates a dictionary or hash table for each point to store the set of points in its neighborhood, and facilitates fast access and calculation; by calculating the total number of points and volume in the neighborhood of each point, the value of the point density is obtained to form a quantized point cloud feature. Implementation significance: Using a dictionary or hash table to store neighborhood points improves the efficiency of space management, facilitates quick search and update of neighborhood information for each point, and facilitates subsequent analysis; provides a quantitative evaluation of point cloud density, helps understand the distribution characteristics of points in the data set, and the result of density calculation is the basis for subsequent high-density area screening. Step S32123 marks the high-density area, and by comparing the density of each point with the set threshold, quickly marks the points that meet the conditions to form a preliminary screening result for the high-density area; the points in the high-density area are clearly defined and can be distinguished from the data in other low-density areas, providing a clear target point set for subsequent data processing. Implementation significance: By retaining only high-density points, the computational complexity of subsequent analysis is significantly reduced, and the processing efficiency of subsequent steps is improved; the identified high-density area is related to the characteristics of the melt, which facilitates subsequent structural analysis, such as object recognition, feature extraction and morphological analysis, which directly affects the accuracy and effectiveness of the final analysis results.

[0190] In summary, in the process of identifying high-density point cloud areas, each step of this embodiment plays a key role, forming a complete analysis chain from data processing and storage to analysis and result extraction. It ensures that the identified high-density areas can reflect the true characteristics of the point cloud data, providing a basis for subsequent operations in practical applications. Overall, the implementation of these steps improves the effectiveness and accuracy of point cloud data and supports more complex subsequent analysis tasks.

[0191] Further, the process of judging whether it meets the structural characteristics of the melt in step S3213 specifically includes the following steps:

[0192] Step S32131: For the neighborhood of each point, the shape features are calculated, and the normal vector is calculated by principal component analysis of the neighborhood points. The normal vector understands the geometric features of the melt and characterizes the curvature of the surface around the point. The melt usually exhibits curvature characteristics;

[0193] Step S32132: construct a connection graph based on the neighbor relationship, use the graph theory method to analyze the connectivity between points; use the connected component labeling method to find areas with high density and structural connectivity;

[0194] Step S32133: By comparing the normal vector direction distribution, point density distribution and shape characteristics of the point cloud with the predetermined melt characteristics, the matching index is calculated, and the distance and similarity between the point cloud and the model are calculated; the melt part is judged according to the set threshold, the points that meet the melt structure characteristics are marked, and the points that do not meet the characteristics are excluded to form the final screened point cloud data set.

[0195] Preferably, step S32131 of this embodiment calculates shape features, and calculates the normal vector (i.e., the direction of the surface tangent) according to the distribution of the neighborhood points by the principal component analysis (PCA) method, providing a quantitative description of the geometric shape of the point cloud; by calculating the curvature of the neighborhood points, the curvature of the surface around the point is further analyzed, and the curvature value can indicate the smoothness of the melt surface and the local shape change. Implementation significance: It is possible to extract geometric features from the point cloud data, making the shape features of the melt clearer; shape features are the key to understanding the structure of the object, laying the foundation for feature matching; judging the smoothness and continuity of the point cloud area according to the shape features and curvature is helpful to distinguish the melt part from the background or noise data, thereby improving the accuracy of data processing. Step S32132 constructs a connection map and connectivity analysis, and constructs a graph structure based on the adjacency relationship between points to indicate which points in the point cloud are connected or adjacent to each other; through the graph theory method, the connected components in the point cloud are marked, and dense and structurally coherent areas can be effectively identified. Implementation significance: Through connectivity analysis, the melt part with overall regionality can be discovered and marked, rather than isolated scattered points; continuity is an important manifestation of melt characteristics, because it helps to determine the integrity of the melt part; by focusing on the analysis of high-density and connected areas, the calculation amount of subsequent feature analysis can be reduced and the data processing process can be optimized. Step S32133 feature matching and threshold judgment, compare the normal vector direction, density distribution and shape characteristics of the point cloud, calculate the similarity index with the known melt feature model, and match it using a mathematical model (such as Euclidean distance, cosine similarity, etc.); judge according to the preset threshold standard, mark the points that meet the conditions as melt, otherwise mark them as background. Implementation significance: By systematically comparing the features of the point cloud, it is helpful to achieve accurate distinction between the melt part and the background; accurate classification results are extremely important for subsequent applications (such as shape analysis, model reconstruction, etc.); using threshold judgment and model matching, a quantitative and repeatable evaluation method is provided, making the data processing process more standardized, which can effectively adapt to different scenarios and requirements in practical applications.

[0196] In summary, this embodiment plays a key role in determining the characteristics of the melt structure, ensuring the effectiveness and accuracy of feature extraction, structural analysis, and feature matching. Through these steps, the messy point cloud data can be effectively processed, and elements with practical significance can be extracted, providing a reliable data basis for subsequent analysis, modeling, and application. It also further enhances the importance of point cloud technology in practical applications such as three-dimensional reconstruction, automated detection, and manufacturing process analysis.
