Description

Technical Field

[0001] This utility model relates to the field of metallurgical industrial equipment monitoring technology, and in particular to a multi-dimensional impact monitoring device for electrodes of an industrial silicon submerged arc furnace. Background Technology

[0002] In the production process of industrial silicon submerged arc furnaces, electrodes, as core conductive components, directly affect production efficiency and operational safety due to their structural stability. However, the furnace working environment is characterized by confined space, high temperature and dust, and limited visibility. When operators use forklifts or furnace tamping vehicles to push materials or tamp the furnace, the tamping rod or forklift arm is prone to colliding with the electrodes. Such collisions can trigger a series of chain reactions: the electrodes sway laterally after impact, disrupting the mechanical fit stability between the electrode and the clamp, leading to uneven current conduction; repeated impacts can form microcracks on the electrode surface, accelerating internal stress accumulation and potentially causing electrode breakage and unplanned downtime; more importantly, the current production model lacks quantitative records of impact events. When serious failures such as electrode breakage occur, it is difficult to trace key parameters such as the frequency and force of impacts, greatly affecting the efficiency of fault analysis and increasing maintenance costs.

[0003] Current technologies for electrode protection have significant limitations: First, they rely on manual observation and recording of impact events, which are affected by the working environment and human factors, making real-time and accurate monitoring impossible; second, traditional electrode monitoring systems (such as current sensors and infrared thermometers) can only monitor electrical parameters or temperature changes and cannot identify damage to electrodes caused by mechanical impacts; third, there is a lack of long-term storage, statistical and analytical mechanisms for impact data, making it impossible to build damage models from historical data and predict potential damage risks to electrodes, resulting in electrode maintenance often being in a reactive state.

[0004] Therefore, in view of the problem that industrial silicon submerged arc furnace electrodes are susceptible to collisions during production and lack effective monitoring methods, there is an urgent need to develop an anti-collision protection analysis system that can capture impact events in real time, quantify and analyze impact parameters, and assist in fault tracing, so as to fill the existing technological gap and improve the safety and service life of the electrodes. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a multi-dimensional impact monitoring device for industrial silicon submerged arc furnace electrodes, which can solve the problem of an anti-collision protection analysis system that can capture impact events in real time, quantify and analyze impact parameters, and assist in fault tracing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-dimensional impact monitoring device for electrodes of an industrial silicon submerged arc furnace, comprising a connecting arm, a clamping module, a clamping tooth module, a connecting key, a vertical rod, a crossbeam module, a data acquisition and processing mechanism, a data and statistics system, and a sensor assembly. The clamping module is fixedly connected to both ends of the inner side of the connecting arm, and the clamping tooth module is fixedly connected to the clamping module.

[0007] The two sides of the connecting arm are movably connected to the crossbeam module via connecting keys, forming a "gate" shaped support structure;

[0008] A vertical rod is fixedly connected to the lower surface of the crossbeam module, and the end of the vertical rod extends into the rectangular groove of the connecting arm;

[0009] Sensor components are installed inside the rectangular slot, and the data acquisition and processing mechanism is mounted on the crossbeam module, connecting the data and the statistical system via a link.

[0010] Preferably, the sensor assembly includes a dynamic force sensor on the left side of the rectangular slot, and a triaxial accelerometer and gyroscope inside the right housing;

[0011] The housing is used to isolate dust and vibration, the triaxial accelerometer covers lateral impact monitoring along the X / Y / Z axes, and the gyroscope detects electrode angle deflection.

[0012] Preferably, the data acquisition and processing mechanism includes a protective shell and a built-in data acquisition and processing module;

[0013] The inner wall of the protective shell is provided with a rectangular mounting groove, and a set of heat dissipation fins are fixed in the rectangular mounting groove. The upper surface of the protective shell has heat dissipation holes corresponding to the rectangular mounting groove, and dustproof copper mesh is installed in the heat dissipation holes.

[0014] Preferably, the upper surface of the crossbeam module is movably connected to an elliptical hook, which serves as a lifting point for hoisting or maintenance; the connecting keys are symmetrically distributed front and back, and are fixedly connected to the crossbeam module to form a load-bearing frame of a "gate"-shaped support structure.

[0015] Preferably, the dynamic force sensor is used to detect the lateral pressure when the electrode is impacted, the triaxial accelerometer monitors the impact acceleration change, and the gyroscope and triaxial accelerometer are encapsulated in the housing. The three devices synchronously collect impact-related data and transmit it to the data acquisition and processing module.

[0016] Preferably, the data acquisition and processing module is used to realize signal amplification, threshold judgment and data temporary storage;

[0017] The heat dissipation fins and heat dissipation holes form a heat dissipation channel, which is suitable for the high temperature environment of the furnace area. The dustproof copper mesh prevents dust from the furnace area from entering the protective shell.

[0018] Preferably, the link between the data acquisition and processing mechanism and the data and statistics system is a wired link or a wireless link. The wired link uses RS485, and the wireless link uses LoRa. The data and statistics system is deployed in the factory control room for long-term storage, hierarchical statistics, and damage model analysis of impact data.

[0019] Preferably, the data and statistics system integrates a fracture analysis auxiliary module, which interfaces with the database of the factory's existing electrode monitoring system via the OPCUA protocol. The existing electrode monitoring system includes a current sensor and an infrared thermometer.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This multi-dimensional impact monitoring device for industrial silicon submerged arc furnace electrodes transmits the impact force through the vertical rod to the rectangular groove of the connecting arm when the electrode is subjected to an external impact. The dynamic force sensor on the left side of the rectangular groove (measurement range 5–50kN, response time <1ms) immediately detects the lateral pressure generated by the impact on the electrode. Simultaneously, it triggers the triaxial accelerometer (measurement range ±20g, resolution 0.001g, sampling frequency 1000Hz) and gyroscope (angle measurement range ±30°, angular velocity range ±500° / s) inside the right outer shell to start monitoring. The triaxial accelerometer captures the impact acceleration changes in the X / Y / Z axes (conventional impacts are concentrated in 0.5–15g), while the gyroscope records the angle deflection data of the electrode after the impact (the maximum deflection after impact can reach 15–25°), realizing comprehensive perception of the impact intensity, direction, and attitude changes.

[0022] This industrial silicon submerged arc furnace electrode multi-dimensional impact monitoring device transmits sensor signals via wired connection to a data acquisition and processing mechanism on the crossbeam module. The data acquisition and processing module within the protective casing (IP65 protection rating, adaptable to working environments of -40–250℃) first amplifies the raw signal, then uses a built-in algorithm to determine the impact threshold (an effective impact requires acceleration >0.5g and duration >100ms, thus filtering out the 0.3–0.4g vibration interference generated during normal furnace operation). The effective data is then temporarily stored (timestamp error <10ms, acceleration measurement error ±2%FS). Simultaneously, the heat dissipation fins in the rectangular mounting slot and the top heat dissipation holes form a convection heat dissipation channel, which, combined with a dustproof copper mesh, blocks dust in the furnace area, ensuring stable module operation in high-temperature, high-dust environments.

[0023] This multi-dimensional impact monitoring device for industrial silicon submerged arc furnace electrodes processes impact data and transmits it via RS485 wired link or LoRa wireless link to a remote data and statistics system in the factory control room. This system performs long-term data storage and hierarchical statistics (categorized by impact force into mild 0.5–2g (stress value 5–15kN), moderate 2–5g (stress value 15–30kN), and severe 5–15g (stress value 30–50kN), and accumulates the count by shift / day / week, with a normal impact frequency of 5–30 times per shift and a daily peak of ≤50 times). The system also constructs a damage model using a built-in fracture analysis auxiliary module. The system assesses the degree of electrode damage using a cumulative damage coefficient (10 points for severe damage, 3 points for moderate damage, and 0.5 points for minor damage; the probability of fracture increases to 30% when the cumulative score is >100 points and to 70% when it is >200 points). Furthermore, the system connects to the factory's existing electrode monitoring system via the OPCUA protocol. Synchronous maintenance alerts are triggered when current fluctuations exceed 1000A or temperature spikes exceed 50°C during an impact. Special attention is paid to events where the angle between the impact direction and the fracture surface is <30° (such events can increase the crack propagation rate by 2–3 times). This multi-dimensional data fusion analysis provides a comprehensive basis for electrode impact protection and maintenance decisions. Attached Figure Description

[0034] Please see Figure 1-4 This utility model provides a technical solution: a multi-dimensional impact monitoring device for electrodes of an industrial silicon submerged arc furnace, including a connecting arm 1, with clamping modules 2 fixedly connected to both ends of the inner side of the connecting arm 1, and two clamping tooth modules 3 (for gripping the electrode and transmitting clamping force) fixedly connected to each clamping module 2.

[0035] The connecting arm 1 has two fixed movable connections on both sides in the middle (symmetrically distributed front and back), and a crossbeam module 7 is fixedly connected between the two front and back connecting keys 4 (forming a "gate" shaped support structure to support the vertical rod 5 and the data module).

[0036] A rectangular slot 10 is formed in the middle of the upper surface of the connecting arm 1 (serving as a sensor mounting cavity to accommodate the end of the vertical rod 5 and the force sensor). A dynamic force sensor 11 (detecting the lateral pressure of the electrode when impacted, model: HBMC16-30KN or OmegaLC803-50KN) is fixedly connected to the inner left wall of the rectangular slot 10. A housing 14 (encapsulating a triaxial accelerometer 13 and a gyroscope 12, isolating dust / vibration) is fixedly connected to the inner right wall of the rectangular slot 10. A triaxial accelerometer 13 (monitoring the acceleration change of the impact, covering lateral impact on the X / Y / Z axes) is fixedly installed inside the housing 14. A gyroscope 12 (detecting the angular deflection of the electrode after impact, both are encapsulated in the housing 14) is fixedly connected to the upper surface of the triaxial accelerometer 13. When the electrode is impacted, the impact force... The force is transmitted through the vertical rod 5 to the rectangular slot 10 of the connecting arm 1. The dynamic force sensor 11 on the left side of the rectangular slot 10 (measurement range 5–50kN, response time <1ms) immediately detects the lateral pressure generated by the impact on the electrode. Simultaneously, it triggers the triaxial accelerometer 13 (measurement range ±20g, resolution 0.001g, sampling frequency 1000Hz) and the gyroscope 12 (angle measurement range ±30°, angular velocity range ±500° / s) in the right outer shell 14 to start monitoring. The triaxial accelerometer 13 captures the impact acceleration changes in the three directions of X / Y / Z (normal impacts are concentrated in 0.5–15g), while the gyroscope 12 records the angle deflection data of the electrode after the impact (the maximum deflection after the impact can reach 15–25°), realizing a comprehensive perception of the impact intensity, direction and attitude changes.

[0037] A vertical rod 5 is fixedly connected to the lower surface of the crossbeam module 7. The end of the vertical rod 5 is located in the rectangular groove 10 (the vertical rod 5 extends to the electrode connection area to transmit the impact force to the sensing module). An elliptical hook 6 (used as a lifting point during hoisting or maintenance) is fixedly and movably connected to the upper surface of the crossbeam module 7. A data acquisition and processing mechanism 8 is fixedly installed on the upper surface of the crossbeam module 7.

[0038] The data acquisition and processing mechanism 8 includes a protective housing 15 and a built-in data acquisition and processing module 20 (for signal amplification, threshold judgment, and data temporary storage). A rectangular mounting slot 19 is provided in the inner wall of the protective housing 15 (providing mounting positions for heat dissipation fins 17). A set of heat dissipation fins 17 is fixedly installed in the rectangular mounting slot 19 (enhancing module heat dissipation efficiency and adapting to the high-temperature environment of the furnace area). A set of equidistant heat dissipation holes 16 are provided on the upper surface of the protective housing 15, corresponding to the rectangular mounting slot 19 (forming heat dissipation channels). Each heat dissipation hole 16 is fitted with a dustproof copper mesh 18 (preventing furnace dust from entering and protecting internal circuitry). The data acquisition and processing mechanism 8 is connected to a remote data and statistics system 9 via a wired (e.g., RS485) or wireless (e.g., LoRa) link (for long-term storage, hierarchical statistics, and damage model analysis of impact data). The data and statistics system 9 is deployed in the factory control room (away from the high temperature and dust of the furnace area) for fracture analysis. The auxiliary module is integrated into the data analysis system and connects to the existing electrode monitoring system in the factory (such as the database of current sensors and infrared thermometers) via the OPCUA protocol. The sensor signal is transmitted to the data acquisition and processing mechanism 8 on the crossbeam module 7 via wired transmission. The data acquisition and processing module 20 inside the protective shell 15 (protection level IP65, adaptable to working environment of -40–250℃) first amplifies the raw signal and then completes the impact threshold judgment through the built-in algorithm (the effective impact must meet the requirements of acceleration >0.5g and duration >100ms, so as to filter the 0.3–0.4g vibration interference generated by the normal operation of the furnace car) and temporarily stores the effective data (timestamp error <10ms, acceleration measurement error ±2%FS). At the same time, the heat dissipation fins 17 in the rectangular mounting slot 19 and the top heat dissipation holes 16 form a convection heat dissipation channel, which, together with the dustproof copper mesh 18, blocks the dust in the furnace area and ensures the stable operation of the module in the high temperature and high dust environment.

[0039] Working principle: When the electrode is subjected to external impact, the impact force is transmitted through the vertical rod 5 to the rectangular groove 10 of the connecting arm 1. The dynamic force sensor 11 on the left side of the rectangular groove 10 (measurement range 5–50kN, response time <1ms) immediately detects the lateral pressure generated by the impact on the electrode, and simultaneously triggers the triaxial accelerometer 13 (measurement range ±20g, resolution 0.001g, sampling frequency 1000Hz) and gyroscope 12 (angle measurement range ±30°, angular velocity range ±500° / s) in the right outer shell 14 to start monitoring. The triaxial accelerometer 13 captures the impact acceleration changes in the three directions of X / Y / Z (normal impacts are concentrated in 0.5–15g), and the gyroscope 12 records the angle deflection data of the electrode after the impact (the maximum deflection after the impact can reach 15–25°), realizing comprehensive perception of the impact intensity, direction and attitude changes.

[0040] The aforementioned sensing signals are transmitted via wired connection to the data acquisition and processing mechanism 8 on the crossbeam module 7. The data acquisition and processing module 20 inside the protective housing 15 (protection level IP65, adaptable to working environment of -40–250℃) first amplifies the original signal, and then completes the impact threshold judgment through the built-in algorithm (the effective impact must meet the requirements of acceleration >0.5g and duration >100ms, so as to filter the 0.3–0.4g vibration interference generated by the normal operation of the furnace car), and temporarily stores the effective data (time stamp error <10ms, acceleration measurement error ±2%FS). At the same time, the heat dissipation fins 17 in the rectangular mounting slot 19 and the top heat dissipation holes 16 form a convection heat dissipation channel, which, together with the dustproof copper mesh 18, blocks the dust in the furnace area and ensures the stable operation of the module in the high temperature and high dust environment.

[0041] The processed impact data is transmitted via RS485 wired link or LoRa wireless link to the remote data and statistics system 9 in the factory control room. This system performs long-term data storage and hierarchical statistics (categorized by impact force into mild 0.5–2g (stress value 5–15kN), moderate 2–5g (stress value 15–30kN), and severe 5–15g (stress value 30–50kN), and accumulates the data by shift / day / week, with a normal impact frequency of 5–30 times per shift and a daily peak of ≤50 times). A damage model is constructed using a built-in fracture analysis auxiliary module (cumulative damage coefficient: A single severe impact is scored as 10 points, a moderate impact as 3 points, and a minor impact as 0.5 points. When the cumulative score is >100 points, the probability of fracture increases to 30%, and when it is >200 points, it increases to 70%. This assesses the degree of electrode damage. In addition, the system connects to the factory's existing electrode monitoring system via the OPCUA protocol. When there is a current fluctuation >1000A or a sudden temperature rise >50℃ during an impact, a synchronous maintenance prompt is triggered. Special attention is paid to events where the angle between the impact direction and the fracture surface is <30° (such situations will increase the crack propagation rate by 2-3 times). This enables multi-dimensional data fusion analysis, providing a comprehensive basis for electrode impact protection and operation and maintenance decisions.
