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 furnaces, and chutes are crucial components of the metallurgical and smelting processes, each playing a specific role in the overall smelting process. Furnace smelting is the extraction and processing of metals or alloys in a high-temperature furnace. The high-temperature furnace is the interior of the furnace, primarily 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. Typically located at the bottom or side of the furnace, it effectively directs the smelted products to the next processing step or collection. The chute operates in the lower part of the high-temperature furnace, at temperatures of approximately 1000°C. The high-temperature melt easily forms a large amount of coke on the chute, which can cause blockage and seriously affect the normal operation of the furnace smelting process. In order to maintain the normal operation of the chute, operators need to go to the site to observe the coking condition of the chute and use a long steel chisel to poke the chute into the coke removal manually at regular intervals. 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 coke removal process, scalding accidents may occur from time to time. Therefore, an automated chute insulation and anti-coking system is urgently needed to replace manual coke removal, avoid scalding accidents caused by high temperature environments, and ensure the safe and stable operation of the chute.
[0003] Prior art one, Chinese patent, application number: 202110617321.6 discloses an online detection device and method for the FeO content of sintered ore with an inclined sleeve structure, 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 outer wall of the middle part 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. The feeding 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 and the feeding is stopped at the same time to avoid material piling; 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. The feeding chute adopts a detachable split structure, which can easily remove the blocked material and reduce the labor intensity of maintenance personnel. However, cleaning coke in a high-temperature environment can easily cause burns, and the efficiency of coke cleaning mostly depends on the experience of the personnel, resulting in poor coke cleaning results.
[0004] Prior art two, Chinese patent, application number: 202110617320.1 discloses an online detection device and method for the FeO content of 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 pile-up; 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 operating 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 residue in aluminum alloy melt, comprising 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; transferring the aluminum alloy liquid from the smelting furnace to a standing furnace, then from the standing furnace to a chute, passing through an online melt purification system, and reaching a transfer sleeve at the end of the chute; during the aluminum alloy liquid casting stage, the aluminum alloy liquid flows downward from the end of the chute into the transfer sleeve; and determining the presence of flux residue by measuring the aluminum liquid injection velocity in the transfer sleeve. Although by pre-determining whether the flux has residual components in the early stage of production, it is ultimately confirmed whether the refining agent is suitable for aluminum alloy melt processing applications, providing support and guarantee for the suitability of different fluxes for aluminum alloy melting and casting processes. However, there is a lack of technical means to detect coking in the chute, and coke removal still needs to be done manually, which is not only inefficient but also prone to causing injuries.
[0006] Currently, the coke cleaning process in the existing technologies 1, 2 and 3 is complicated, time-consuming and labor-intensive, and prone to burn accidents, resulting in poor safety of the coke cleaning process. Therefore, the present invention provides an automated chute heat preservation and anti-coking system, method and device. Summary of the Invention

[0041] Temperature acquisition devices are installed at multiple locations within the chute to monitor the temperature of different areas in real time. The temperature acquisition devices continuously acquire temperature data of the melt material within the chute and feed it back to the intelligent feedback system. The intelligent feedback component sets a critical value t based on the characteristics of the melt material to determine whether there is a coking risk. When the temperature displayed by the temperature acquisition device in a certain area is lower than the critical value t, the current area is determined to have a potential coking risk.
[0042] The intelligent feedback component controls two adjacent heating elements to start heating. The heating elements are installed in the refractory material outside the chute wall and provide heat to the heating area through a circular path. After the heating elements are working, the temperature gradually rises until the temperature detected by the temperature acquisition device is 10° higher than the critical value t, that is, when it reaches t+10°, the heating stops.

[0050] Among them, high-temperature wireless temperature sensors, heating elements, laser scanning cameras and defocusing equipment are connected to the intelligent feedback component;
[0051] The high-temperature wireless temperature sensor is embedded in the refractory layer. The inner side of the refractory layer is a chute, and the inside of the chute is a high-temperature melt.

The decoking arm can be freely extended and retracted to ensure that it can be moved to various positions in the chute. Driven by an intelligent feedback component, it starts working when the laser scanning camera detects the coking situation and provides its specific location information.

Significance: Real-time temperature monitoring can effectively prevent the melt from solidifying due to excessively low temperature, thereby reducing the occurrence of coking; temperature data provides an important basis for subsequent heating and cleaning measures, ensuring that the system operates within a safe and efficient temperature range. When the temperature of a certain area of the chute is lower than the critical value, the heating and insulation component can automatically start the heating elements of the two adjacent parts for heating to maintain a suitable temperature. Significance: Keep the temperature of the chute within the set range to prevent the high-temperature melt from coking due to temperature reduction; the automation of heating measures reduces the need for manual intervention and improves the operational stability and safety of the system. The coking visual monitoring component monitors the flow of high-temperature melt in the chute and determines whether coking occurs; once coking is found, the coordinate information of the coking area can be obtained and transmitted to the intelligent feedback component in a timely manner. Significance: Through real-time monitoring, early signals of coking can be effectively captured, and timely measures can be taken to deal with them, reducing interference with the production process; improving the understanding of the coking situation and providing accurate data support for coking removal.

Heating and insulation component 2 When the temperature of a certain area of the chute is lower than the critical value, the component can automatically start the heating elements of the two adjacent parts for heating to maintain a suitable temperature. Significance: Keep the temperature of the chute within the set range to prevent the high-temperature melt from coking due to temperature reduction; the automation of heating measures reduces the need for manual intervention and improves the operational stability and safety of the system. The coking visual monitoring component 3 monitors the flow of the high-temperature melt in the chute and determines whether coking occurs; once coking is found, the coordinate information of the coking area can be obtained and transmitted to the intelligent feedback component in a timely manner. Significance: Through real-time monitoring, early signals of coking can be effectively captured, and timely measures can be taken to deal with them, reducing interference with the production process; improving the understanding of the coking situation and providing accurate data support for coking removal.

[0075] In summary, the mutual cooperation of the various components of this embodiment in the system forms a complete automated and intelligent thermal insulation and anti-coking solution. It helps to: reduce the number of manual interventions and effectively reduce human errors; improve the reliability and stability of materials during the smelting process and ensure production safety; optimize resource consumption through real-time monitoring and feedback, that is, improve smelting efficiency and reduce energy consumption; significantly reduce the negative impact of coking on the production process and ensure smooth material transportation. It makes the smelting process more scientific, efficient and automatic, and lays a solid foundation for the intelligent development of the modern metallurgical industry. This embodiment realizes the automation and intelligence of chute anti-coking; there is no need for manual coke cleaning operations, which avoids scalding accidents caused by high temperature environments, and is an automated chute thermal insulation and anti-coking system that improves the efficiency, safety, energy saving and environmental protection of the furnace as a whole.
[0076] Furthermore, the temperature monitoring component 1 specifically includes:
[0077] The signal acquisition module is used for temperature acquisition equipment to directly contact the chute wall through the adjacent thermocouple or thermal resistance sensor to obtain actual temperature information; the detected temperature information is converted into an analog voltage signal proportional to the temperature; the analog voltage signal is amplified, filtered and linearized to obtain a conditioned analog voltage signal;
[0078] The analog-to-digital conversion module is used to input the conditioned analog signal into the analog-to-digital converter and quantize the analog voltage value of each sample into a corresponding digital value; the converted digital signal passes through the digital signal processor for smoothing and filtering;
[0079] Among them, the expression for improving the efficiency of the analog-to-digital converter is:
[0080] Setting multiple parameters that affect the efficiency of the analog-to-digital converter: F s represents the sampling frequency, ENOB represents the effective number of bits, V ref Indicates the reference voltage, T conv Indicates the conversion time, P total Indicates total power consumption, BW indicates signal bandwidth;
[0081] Comprehensive performance matrix, construct input parameter matrix X and impact matrix A:
[0082] X=[F s ENOB V ref T conv P total BW]
[0083]
[0084] where each k ij Indicates the interaction between different parameters.
[0085] Nonlinear correction term, in order to make the equation include nonlinear effects, a nonlinear correction term Φ can be introduced:
[0086]

It not only considers the linear combination of different parameter configurations but also introduces the complex interactions and nonlinear characteristics between the parameters, making this expression more explanatory and practical in practical applications.
[0092] The signal output module is used to output the temperature value after digital signal processing through the interface for processing and judgment by the intelligent feedback component 5.
[0093] Preferably, the signal acquisition module of this embodiment directly contacts the chute wall using a thermocouple or thermistor sensor to accurately acquire the actual temperature. The measured temperature information is converted into an analog voltage signal proportional to the temperature. The analog signal is amplified, filtered, and linearized to ensure signal quality for subsequent processing. Significance: Direct measurement and processing minimizes measurement error and improves the system's response accuracy. The conditioned signal effectively removes noise, enhances system stability, and provides a reliable input for subsequent digital conversion. The analog-to-digital conversion module converts the conditioned analog signal into a digital signal using an analog-to-digital converter for digital processing. The converted digital signal is smoothed and filtered by a digital signal processor to remove transient fluctuations and high-frequency noise. Significance: The digital signal easily interacts with modern computers and digital instruments, laying the foundation for subsequent data analysis and processing. Efficient digital processing enables more real-time temperature monitoring and faster adaptation to environmental changes. Nonlinear correction and comprehensive performance: By constructing a performance matrix and nonlinear correction terms, the overall efficiency of the analog-to-digital converter is evaluated, including consideration of the interactions of multiple variables. This allows the system to adjust in real time to varying operating conditions to improve overall conversion efficiency.

Linearization processing makes the signal output consistent in different temperature ranges, facilitating subsequent conversion and comparison, and ensuring data consistency. Step S12 performs analog-to-digital conversion and digital signal processing. The conditioned analog signal is fed into an analog-to-digital converter (ADC) to quantize the analog voltage value into a corresponding digital value, completing the signal's transition from continuous to discrete. A digital signal processor (DSP) then smoothes and filters the converted digital signal to further eliminate noise and instability in the data. Implementation significance: After converting the analog signal to a digital signal, the data can be adapted for computer processing, facilitating subsequent analysis and algorithm application. Smoothing and filtering techniques improve signal quality, reduce measurement errors, and make subsequent analysis more reliable. Digital signals are more easily interacting with modern computers and digital systems, facilitating intelligent computing and real-time data processing.

[0138] Furthermore, if Figure 5 As shown, the process of starting the heating elements of two adjacent parts of a certain area in step S2 specifically includes the following steps:
[0139] Step S21: Temperature acquisition devices are installed at multiple locations within the chute to monitor the temperature of different areas of the chute in real time. The temperature acquisition devices continuously acquire temperature data of the melt material in the chute and feed it back to the intelligent feedback system. The intelligent feedback component sets a critical value t based on the characteristics of the melt material to determine whether there is a coking risk. When the temperature displayed by the temperature acquisition device in a certain area is lower than the critical value t, the current area is determined to have a potential coking risk.
[0140] Step S22: The intelligent feedback component controls two adjacent heating elements to start heating. The heating elements are installed in the refractory material outside the chute wall and provide heat to the circumferential heating area. After the heating elements are working, the temperature gradually rises until the temperature detected by the temperature acquisition device is 10° higher than the critical value t, that is, when it reaches t+10°, the heating stops.
[0141] Step S23: In the conveying direction of the chute, a layer of heating elements is arranged every h (range 20-50 cm), and the temperature acquisition equipment is staggered. From the bottom of the kiln to the next kiln, m layers of heating elements are arranged along the chute to ensure uniform temperature and form multi-layer heating from bottom to top. During the heating process, the temperature acquisition equipment continuously acquires data, and the intelligent feedback component detects the temperature changes in each area in real time. If the temperature is detected to fall below the critical value t again, the heating process of the two adjacent parts of the heating elements is repeated.
[0142] Preferably, in step S21 of this embodiment, temperature monitoring and risk assessment can monitor the temperature of different areas in real time by installing temperature acquisition equipment at multiple locations inside the chute; it can actively collect data and provide real-time temperature change information; the intelligent feedback component sets a critical value t according to the characteristics of the melt material, and uses it to determine whether there is a coking risk; when the temperature of a certain area is lower than the critical value, it automatically determines that the area has a potential coking risk. Implementation significance: through real-time monitoring and timely judgment, it is ensured that measures can be taken as early as possible before the coking risk occurs, thereby reducing the risk of accidents; the collection and analysis of temperature data provides a basis for subsequent decision-making, which can optimize the production process and improve production safety and efficiency. In step S22, the start-up and control of the heating element, the intelligent feedback component controls the two adjacent heating elements to start heating in order to achieve the purpose of raising the temperature; the heating element provides heat to the circumferential heating area, and the temperature gradually rises; the temperature change is continuously monitored by the temperature acquisition device to ensure that heating is stopped immediately after reaching t+10° to prevent overheating. Significance of implementation: The dynamic control of the intelligent feedback system enables the heating process to quickly respond to temperature changes, optimize heating efficiency, and avoid energy waste; preventing overheating can protect the integrity of the melt material and the chute structure, reduce maintenance costs, and extend the service life of the equipment. Step S23: Heating area layout and data feedback: In the conveying direction of the chute, a layer of heating elements is arranged every h (20-50cm) (see attached Figure 6) and are arranged in a staggered manner with temperature acquisition equipment. This layout ensures uniform coverage of the heating area and improves the heating effect; m layers of heating elements are arranged along the chute from the bottom of the kiln to the next kiln, forming an effective multi-layer heating structure. At the same time, temperature data is continuously acquired during the heating process to achieve all-round temperature monitoring. Implementation significance: A reasonable layout design helps to achieve uniform heating and prevent the coking of materials due to local low temperatures, thereby ensuring the continuity and stability of production; continuous temperature monitoring and feedback mechanisms ensure that the system can adjust the heating strategy in real time. If the monitored temperature drops to the critical value t, heating will be immediately carried out; it can effectively prevent problems caused by temperature fluctuations.
[0143] In summary, step S21 of this embodiment focuses on the accurate acquisition and judgment of data, providing a basis for subsequent appropriate measures; step S22 ensures safety and efficiency by controlling the heating process, and sets a suitable heating range to prevent overheating; step S23 ensures the uniformity of the overall heating process and the flexibility of response by optimizing the layout and continuous monitoring, thereby improving the intelligence level of the system.

[0144] Furthermore, if Figure 7 As shown, the process of determining whether coking occurs in the area within the chute in step S3 specifically includes the following steps:
[0145] Step S31: A belt conveyor is built parallel to the chute, and a laser scanning camera is installed at the upper end of one side of the belt conveyor. The laser scanning is used to obtain the flow of the high-temperature melt in the conveyor chute, generate three-dimensional coordinate data, and apply a filtering algorithm to process the image to remove interference.
[0146] Step S32: Analyze the acquired three-dimensional coordinate data of the laser scan, use point cloud deformation analysis technology to correct the data, and extract the three-dimensional characteristics and volume information of the melt; convert the measured melt volume into the mass flow rate of the material through formula calculation, using the following formula:

[0149] Step S33: Input the monitored material flow data into the intelligent feedback control component to optimize the material delivery plan and grasp the flow changes in real time; according to the monitoring results, adjust the equipment control parameters, optimize the data collection frequency and set the alarm threshold; when the flow is high, increase the frequency of laser scanning.
[0150] Preferably, in step S31 of this embodiment, laser scanning and data acquisition can monitor the flow of high-temperature melt in real time by installing a laser scanning camera on the belt conveyor next to the chute; the three-dimensional coordinate data generated by the laser scanning reflects the actual state of the melt and can provide a data basis for subsequent analysis; a filtering algorithm (average filtering or frequency domain filtering) is applied to process the laser scanning image to remove interference and ensure the clarity and validity of the data. Implementation significance: It provides accurate basic data for the subsequent judgment of coking risk. The accuracy of this link directly affects the validity of subsequent analysis; through filtering, noise interference is eliminated, and the data quality is improved, thereby improving the measurement accuracy of the overall system. Step S32 data analysis and flow calculation uses point cloud deformation analysis technology to correct the acquired three-dimensional coordinate data and accurately extract the three-dimensional characteristics and volume information of the melt; the measured melt volume is converted into the mass flow rate of the material through a formula, and the calculated mass flow rate provides quantitative information on the melt flow. Implementation significance: By calculating the mass flow rate, the flow state of the melt can be quantified, providing a specific numerical basis for subsequent coking judgment; data correction and volume information extraction improve the understanding of the melt flow characteristics, which helps to accurately judge whether there is a coking risk under specific circumstances. Step S33 intelligent feedback and optimization control inputs the monitored material flow data into the intelligent feedback control component to achieve real-time monitoring and analysis of the flow; based on the monitoring results, the intelligent feedback system can automatically adjust the equipment control parameters and optimize the data acquisition frequency, as well as set reasonable alarm thresholds to improve the system response capability; when a high flow rate is detected, the laser scanning frequency is accelerated to achieve a rapid response to changes in the melt flow, facilitating timely measures. Implementation significance: Through data monitoring and feedback control, the material delivery plan can be optimized, thereby improving production efficiency; dynamic adjustment and optimization operations can effectively reduce the probability of coking, improve the fluidity and processing efficiency of materials, and reduce unexpected risks in production.
[0151] In summary, through the three steps above, this embodiment achieves closed-loop management from data collection and analysis to feedback control, enabling real-time monitoring of high-temperature melt flow and effective assessment of coking risks. The technical effects and implementation significance of each step contribute to the ultimate goal, providing strong support for ensuring production safety and efficiency.
[0152] Furthermore, the process of extracting the three-dimensional features and volume information of the melt in step S32 specifically includes the following steps:
[0153] Step S321: Generate a point cloud data set containing the spatial coordinates (X, Y, Z) of the melt; perform geometric correction on the obtained point cloud using deformation analysis to identify the melt part and background, and output the corrected point cloud data, focusing on the actual shape of the melt;
[0154] Step S322: extracting important three-dimensional features based on the corrected point cloud data, including volume, surface area, and shape descriptors (such as aspect ratio, curvature, etc.);
[0155] Step S323: Calculate the volume of the melt by combining the point cloud data with the voxel method, grid reconstruction or integration method; and output the extracted three-dimensional feature data and melt volume information.
[0156] Preferably, step S321 of this embodiment involves point cloud data correction and separation. This involves geometrically correcting the original point cloud data using deformation analysis techniques to correct for geometric distortions caused by errors during the scanning process, thereby making the three-dimensional shape of the melt more accurate. An algorithm is then used to distinguish the melt from the background, ensuring that subsequent analysis focuses solely on the melt's three-dimensional features. The corrected point cloud data specifically expresses the melt's true form, eliminating redundant data and providing a more focused view of the target object. Significance: Accurate geometric correction and background separation help ensure the accuracy of subsequent feature extraction and are the foundation for feature extraction and volume calculation. Appropriate filtering and cleaning of the point cloud data reduces the computational burden of subsequent analysis and improves processing efficiency. Step S322 involves extracting key three-dimensional features of the melt, including volume, surface area, and shape descriptors (such as aspect ratio and curvature). These features can help describe the melt's geometric properties and flow state. By setting shape descriptors (such as moment of inertia and roundness), a more comprehensive analysis of the melt's shape can be performed to identify potential problems in its flow. Implementation significance: The extracted three-dimensional features provide quantitative support for subsequent analysis and judgment, especially playing a key role in determining whether there is a risk of coking; through a comprehensive understanding of the geometric characteristics of the melt, process control and material flow management can be improved to achieve higher production stability and efficiency. 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 changing 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 3D melt features and volume information in this embodiment achieves accurate data acquisition, feature extraction, and volume calculation. This not only provides a quantitative basis for in-depth analysis of the melt's physical properties, but also offers important decision-making support for subsequent production process optimization, fault warning, and process improvement.
[0158] Furthermore, the process of identifying the melt portion and the background in step S321 specifically includes the following steps:
[0159] Step S3211: Calculate the average coordinates of each point to generate the 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 this 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's 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] Among them (T x ,T y ,Tz ) are the components of the translation part, and the last line is used to represent the 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 dataset; establish a connection map of adjacent points, and build a local neighborhood model for each point to identify areas with high point density; based on density analysis and a set threshold, remove points in sparse areas to form a pre-screened point cloud dataset;
[0177] Step S3213: Analyze the neighborhood distribution characteristics of each remaining point in the point cloud dataset after removing the initially screened points, 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 dataset by screening and filtering the point cloud.
[0178] Preferably, step S3211 of this embodiment calculates the average coordinates of all points to generate a global center, providing 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, allowing all data points to be adjusted in a consistent manner. Each point undergoes a linear coordinate transformation by applying the transformation matrix, thereby eliminating geometric errors generated during the scanning process. Implementation significance: By coordinating the spatial position of the point cloud data, the geometric features of the melt are ensured to be presented in an optimized state, providing an accurate data foundation for subsequent analysis. A unified coordinate standard is established for data collected from different data sources or under different conditions, making processing in subsequent steps more consistent. Step S3212 analyzes the spatial relationship between each point and establishes an adjacency matrix between points, mapping the connections between each point in the dataset. A local model is constructed for each point, from which high-density areas are identified to ensure effective focus on the melt. Based on a preset density threshold, relatively sparse points are eliminated to form a preliminary integrated point cloud dataset. 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.; based on 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 helps to improve the quality and validity 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, ensuring data quality at each step, achieving a balance between computational efficiency and result reliability, and providing 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 i =(x i ,v i ,z i ), 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 The reference to 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, which constitute the preliminary screening results of high-density areas.
[0189] Preferably, step S32121 of this embodiment selects a neighborhood radius r and finds points within 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 provides the necessary spatial context 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 subsequent recognition effect of high-density areas, making the processing more efficient. Step S32122 generates a neighborhood model and calculates 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 point density value 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 assessment of point cloud density, which helps to understand the distribution characteristics of points in the data set. The result of the 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 areas are 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, each step in this embodiment plays a critical role in the identification of high-density areas. From data processing and storage to analysis and result extraction, a complete analytical chain is formed. This ensures that the identified high-density areas reflect the true characteristics of the point cloud data, providing a foundation for subsequent operations in practical applications. Overall, the implementation of these steps improves the validity and accuracy of point cloud data, supporting more complex subsequent analytical tasks.
[0191] Furthermore, the process of determining whether the structure characteristics of the melt are met in step S3213 specifically includes the following steps:
[0192] Step S32131: For each point's neighborhood, calculate the shape features and calculate the normal vector through 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 graph theory methods 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. By using the principal component analysis (PCA) method, the normal vector (i.e., the direction of the surface tangent) is calculated based on the distribution of neighborhood points, 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. The curvature value can indicate the smoothness of the melt surface and the local shape change. Implementation significance: Geometric features can be extracted from point cloud data, making the shape features of the melt clearer; shape features are the key to understanding the structure of an object and lay the foundation for feature matching; judging the smoothness and continuity of the point cloud area based on shape features and curvature helps to distinguish the melt part from background or noise data, thereby improving the accuracy of data processing. Step S32132 constructs a connection map and connectivity analysis. Based on the adjacency relationship between points, a graph structure is constructed to indicate which points in the point cloud are connected or adjacent to each other; through graph theory methods, the connected components in the point cloud are marked, which can effectively identify dense, structurally coherent areas. Implementation significance: Through connectivity analysis, melt parts with overall regional characteristics 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 analyzing high-density and connected areas, the amount of calculation for subsequent feature analysis can be reduced, and the data processing process can be optimized. Step S32133 Feature matching and threshold judgment compares the normal vector direction, density distribution, and shape characteristics of the point cloud, calculates the similarity index with the known melt feature model, and uses mathematical models (such as Euclidean distance, cosine similarity, etc.) for matching; judges according to the preset threshold standard, and marks the points that meet the conditions as melt, otherwise they are marked 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 melt structural characteristics, ensuring the effectiveness and accuracy of feature extraction, structural analysis, and feature matching. These steps enable effective processing of cluttered point cloud data, extracting meaningful elements and providing a reliable data foundation for subsequent analysis, modeling, and applications. This also further enhances the importance of point cloud technology in practical applications such as 3D reconstruction, automated inspection, and manufacturing process analysis.
[0197] This embodiment also provides an embodiment of an automated chute heat preservation and anti-coking device. In this embodiment, the automated chute heat preservation and anti-coking device is applied to the automated chute heat preservation and anti-coking system in the above embodiment. The automated chute heat preservation and anti-coking device specifically includes: a high-temperature wireless temperature sensor 6, a heating element 7, a laser scanning camera 8, and a coke cleaning device 9;
[0198] Among them, the high-temperature wireless temperature sensor 6, the heating element 7, the laser scanning camera 8 and the de-coking device 9 are connected to the intelligent feedback component 5;
[0199] Preferably, the high-temperature wireless temperature sensor 6 of this embodiment can accurately measure the temperature in the chute in a high-temperature environment and transmit the data to the control system wirelessly, with anti-interference ability and high stability; it monitors the temperature changes in the chute in real time to ensure that the temperature is maintained within the set range to prevent the temperature from being too low and causing the material to coke. Under the feedback control of the temperature sensor 6, the heating element 7 (such as an electric heating pipe, hot air furnace, etc.) is responsible for maintaining or raising the temperature of the material by heating the chute; the heating element 7 can automatically adjust according to actual needs to ensure uniform heating; maintain the temperature in the chute stable to prevent coking due to insufficient temperature during the flow of materials. The laser scanning camera 8 can obtain the material morphology and distribution information in the chute in real time, and obtain high-precision three-dimensional images by projecting laser beams. The three-dimensional images help track the flow state and height changes of the material; provide real-time feedback and monitoring to ensure smooth flow of materials in the chute, and promptly detect and deal with coking or blockage problems. After detecting coking, the coke cleaning equipment 9 can clean the coked material through mechanical or physical means (such as vibration, scraping or impact). Combined with the feedback from the laser scanning camera 8, it can accurately identify the location and degree of coking; clean the coke in real time to ensure smooth material flow and reduce production stagnation and maintenance work.
[0200] In summary, this embodiment can realize real-time monitoring of the temperature and material status in the chute, ensuring that thermal management and material flow are in the optimal state; the cooperation of the integrated high-temperature wireless temperature sensor 6 and the heating element 7 can effectively prevent the material from coking during the transmission process and improve the system reliability; the cooperation of the laser scanning camera 8 and the decoking equipment 9 can quickly detect and deal with the coking problem, thereby reducing the time of sudden failures and maintenance.
[0201] This embodiment prevents material coking and reduces downtime caused by equipment failure, thereby improving production continuity and efficiency. Real-time temperature monitoring and intelligent heating make the heating process more efficient, reduce ineffective energy consumption, and thus reduce production costs. Maintaining the material at an optimal temperature helps improve the quality of the final product and avoid product defects caused by coking. It can also reduce unnecessary maintenance and overhauls, improve the reliability and long-term effectiveness of the equipment, and thus enhance the competitiveness of the enterprise. This has formed a highly efficient and intelligent automated chute insulation and anti-coking device, greatly improving temperature control accuracy and material flowability, and its significance for industrial production is far-reaching.
