Description

Technical Field

[0001] The invention belongs to the technical field of online monitoring of the operation of a central transmission concentrator, and relates to an online monitoring system for the operation of a central transmission concentrator based on artificial intelligence. Background Art

[0002] The central hydraulic transmission concentrator is widely used as the main equipment for leaching and washing. It has the functions of concentrating, washing and buffering, and is widely used in mineral processing, chemical industry, metallurgy, sewage treatment, environmental protection and other industries. Compared with other concentrating equipment, the concentrator has the advantages of small footprint, low energy consumption and high efficiency. It is currently widely used in mineral processing plants. Since many mines are in remote areas, they still use some outdated equipment with low automation, and still use manual supervision with slow response speed. Therefore, the online monitoring and analysis system of the central transmission concentrator based on artificial intelligence is of great significance and role.

[0003] In the prior art, there are also some related solutions related to the operation of the thickener, for example, the invention patent application of an automatic control device and method for preventing the thickener from rake pressure and bottom blockage with the Chinese patent publication number CN113082850B, which includes a discharge system, a flushing system, a reflux system and an automatic control system, and the automatic control system includes a PLC controller, an input analog signal unit and an actuator. The present invention also provides an automatic control method for the above-mentioned device, which monitors the rake frame stroke and the rake frame resistance state in real time, controls the valve opening and opening and the speed of the variable frequency delivery pump through PLC, realizes the continuous operation of the thickener, prevents the occurrence of bottom blockage and rake pressure accidents of the thickener, improves the stable operation efficiency of the thickener, thereby reducing maintenance costs and avoiding safety and environmental accidents.

[0004] Another invention patent application for a control system and method for a concentrator with a Chinese patent publication number of CN113069801B adjusts the lifting height of the rake frame according to the rotational resistance of the rake frame; wherein the rotational resistance is proportional to the pressure value of the pressure gauge; adjusts the rotation speed of the rake frame according to the thickness of the mud bed in the concentrating tank; and adjusts the amount of flocculant added according to the suspended matter concentration of the overflow water in the overflow weir of the concentrating tank; the present invention achieves the technical effect of improving the automation degree of the concentrator, avoiding the occurrence of the rake pressure phenomenon to the greatest extent, improving the working efficiency of the concentrator, and extending the service life of the concentrator.

[0005] Although the above scheme proposes some solutions for the concentrator, it still has certain limitations: on the one hand, the existing scheme can automatically lift the rake frame according to the resistance of the rake arm of the rake frame, or adjust the rotation speed of the rake frame according to the thickness of the mud bed in the concentrating tank and adjust the amount of flocculant added according to the suspended matter concentration of the overflow water in the overflow weir of the concentrating tank. The signal detection is relatively comprehensive and relatively safe, but the existing scheme lacks the connection between the feeding system and the underflow discharge system of the concentrator, which leads to the concentrator being shut down if the feeding speed is too fast or the bottom discharge speed is too slow during the feeding process, requiring real-time manual participation, resulting in the problem of low working efficiency of the concentrator.

[0006] On the other hand, the existing scheme ignores the pressure abnormality of the concentrator tank caused by abnormalities in other components of the concentrator, and thus fails to detect and deal with the pressure abnormality in time, and fails to avoid extended downtime due to equipment failure, thereby extending maintenance time and cost, which is not conducive to ensuring the stable operation of the concentrator. Summary of the invention

[0007] In view of this, in order to solve the problems raised in the above background technology, an online monitoring system for the operation of a central transmission concentrator based on artificial intelligence is proposed.

[0008] The purpose of the present invention can be achieved through the following technical solutions: The present invention provides an online monitoring system for the operation of a central transmission concentrator based on artificial intelligence, including: a pressure analysis module, a control terminal, a pressure analysis module, an operation data analysis module, a pressure abnormality cause analysis module and a database.

[0009] The pressure analysis module is used to record the components associated with the change of the pressure of the concentrator tank in the target central transmission concentrator as the changed components of the target central transmission concentrator, detect the concentrator tank of the target central transmission concentrator in real time, obtain the concentrator tank pressure of the target central transmission concentrator and the current state of the changed components, and analyze the state change requirements of the changed components of the target central transmission concentrator based on this. If it is a change requirement, the control terminal is executed, wherein the changed components include a feed port, a rake frame and a discharge port.

[0010] The control terminal is used to control the status change of each changed component of the target center transmission concentrator.

[0011] The pressure analysis module is used to obtain the pressure of the concentrator tank of the target central transmission concentrator detected each time during the monitoring time period, and analyze the pressure abnormality evaluation of the concentrator tank of the target central transmission concentrator. If it is a pressure abnormality, the operation data analysis module is executed, otherwise, the pressure analysis module is executed.

[0012] The operation data analysis module is used to record the components associated with the pressure of the concentrator tank in the target central transmission concentrator as the designated components of the target central transmission concentrator, obtain the operation data of the designated components of the target central transmission concentrator, and analyze the operation conditions of the designated components of the target central transmission concentrator, wherein the designated components include a scraper blade, a scraper arm, a central rotating support, an overflow weir plate and a flow stabilizing cylinder.

[0013] The pressure abnormality cause analysis module analyzes the pressure abnormality cause of the concentrator tank of the target central transmission concentrator based on the operation status of each designated component of the target central transmission concentrator and feeds back the result.

[0014] The database is used to store the maximum protection pressure value of the target central transmission thickener itself, the maximum strain of the scraper of the target central transmission thickener during operation, the standard gap width between the scraper of the target central transmission thickener and the pool bottom, and the standard operating speed of the scraper arm of the target central transmission thickener.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention obtains the concentrating tank pressure of the target central transmission concentrator and the current status of each changed component, analyzes the status change requirements of each changed component of the target central transmission concentrator, and changes its status. According to the detected concentrating tank pressure of the target central transmission concentrator, the adjustment requirements of the process flow of the target central transmission concentrator are analyzed, which is conducive to accurate and convenient operation and real-time adjustment, and is also conducive to preventing the occurrence of pressure rake or leakage accidents of the target central transmission concentrator.

[0016] 2. The present invention analyzes the pressure anomaly evaluation of the concentrator tank of the target central transmission concentrator. If it is a pressure anomaly, the cause of the pressure anomaly is further analyzed, which helps to timely discover and deal with the pressure anomaly, avoids extended downtime due to equipment failure, improves production efficiency, and reduces production costs.

[0017] 3. The present invention analyzes the operating conditions of each designated component of the target central transmission concentrator, and based on the analysis, analyzes the cause of the abnormal pressure in the concentrator tank of the target central transmission concentrator, which helps maintenance personnel to quickly and accurately find the fault point, reduce maintenance time and cost, and is conducive to timely discovering abnormal trends in equipment operation, thereby preventing the occurrence of faults, and further helping to ensure the stable operation of the concentrator and avoid production interruptions and losses caused by faults.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 As shown, the present invention provides an online monitoring system for the operation of a central transmission concentrator based on artificial intelligence, and the specific modules are distributed as follows: a pressure analysis module, a control terminal, a pressure analysis module, an operation data analysis module, a pressure abnormality cause analysis module and a database. Among them, the connection mode between the modules is: the pressure analysis module is connected to the control terminal, the control terminal is connected to the pressure analysis module, the pressure analysis module is respectively connected to the pressure analysis module and the operation data analysis module, the operation data analysis module is connected to the pressure abnormality cause analysis module, and the database is respectively connected to the pressure analysis module, the pressure analysis module and the operation data analysis module.

[0024] The pressure analysis module is used to record the components associated with the change of the pressure of the concentrator tank in the target central transmission concentrator as the changed components of the target central transmission concentrator, detect the concentrator tank of the target central transmission concentrator in real time, obtain the concentrator tank pressure of the target central transmission concentrator and the current state of the changed components, and analyze the state change requirements of the changed components of the target central transmission concentrator based on this. If it is a change requirement, the control terminal is executed, wherein the changed components include a feed port, a rake frame and a discharge port.

[0025] It should be noted that the module implementation flow diagram is as follows Figure 2 shown.

[0026] As a preferred feasibility example, in the process of analyzing the state change requirements of each changed component of the target central transmission concentrator, it is necessary to construct the representative value of the state of each changed component of the target central transmission concentrator. The specific analysis method includes: extracting the concentrator tank pressure of the target central transmission concentrator , analyze the representative values ​​of the states of each changed component of the target central transmission concentrator ,in , is the number of each changed component, is the maximum protection pressure value of the target central transmission concentrator itself extracted from the database, When , it means that the feed port, rake frame and discharge port of the target center transmission concentrator should be in the following states: reduce feed flow, raise rake frame height and increase discharge flow. When , it means that the states of the feed port, rake frame and discharge port of the target central transmission concentrator are to increase the feed flow, reduce the rake frame height and reduce the discharge flow respectively.

[0027] It should be noted that the first changed component part is the feed port, the second changed component part is the rake frame, and the third changed component part is the discharge port.

[0028] As a preferred feasibility example, the state change requirements of each changed component of the target central transmission concentrator include: extracting the current state of each changed component of the target central transmission concentrator, obtaining the current state representative value of each changed component of the target central transmission concentrator, and comparing them with their corresponding state representative values. If the current state representative value of a changed component of the target central transmission concentrator is inconsistent with its corresponding state representative value, the state change requirement of the changed component of the target central transmission concentrator is recorded as a required change requirement, thereby obtaining the state change requirements of each changed component of the target central transmission concentrator.

[0029] It should be noted that the specific method of obtaining the current state representative value of each changed component of the target central transmission concentrator is: if the current state of the feed port of the target central transmission concentrator is to reduce the feed flow rate, the current state representative value of the feed port of the target central transmission concentrator is recorded as 1; if the current state of the feed port of the target central transmission concentrator is to increase the feed flow rate, the current state representative value of the feed port of the target central transmission concentrator is recorded as 2.

[0030] If the current state of the rake frame of the target center transmission concentrator is to increase the rake frame height, the current state representative value of the rake frame of the target center transmission concentrator is recorded as 1; if the current state of the rake frame of the target center transmission concentrator is to reduce the rake frame height, the current state representative value of the rake frame of the target center transmission concentrator is recorded as 2.

[0031] If the current state of the discharge port of the target central transmission concentrator is to increase the discharge flow rate, the current state representative value of the discharge port of the target central transmission concentrator is recorded as 1; if the current state of the discharge port of the target central transmission concentrator is to reduce the discharge flow rate, the current state representative value of the discharge port of the target central transmission concentrator is recorded as 2.

[0032] The control terminal is used to control the status change of each changed component of the target center transmission concentrator.

[0033] It should be noted that the schematic diagram of the change of the feed inlet, rake frame and discharge port of the target center transmission concentrator is as follows Figure 3 shown.

[0034] As a preferred feasibility example, the specific control method of the state change of each changed component part of the target central transmission concentrator includes: extracting the state change requirements of each changed component part of the target central transmission concentrator.

[0035] If the state change requirement of the feed port of the target central transmission concentrator is a change requirement, the specific state change requirement of the feed port of the target central transmission concentrator is obtained. If it is changed from reducing the feed flow to increasing the feed flow, the speed of the feed pump is increased; if it is changed from increasing the feed flow to reducing the feed flow, the speed of the feed pump is reduced.

[0036] If the state change requirement of the rake frame of the target center transmission concentrator is a change requirement, the specific state change requirement of the rake frame of the target center transmission concentrator is obtained. If it is changed from raising the rake frame height to lowering the rake frame height, the PLC controller automatically sends a signal to control the hydraulic oil circuit through the solenoid valve to lower the rake frame. If it is changed from lowering the rake frame height to raising the rake frame height, the PLC controller automatically sends a signal to control the hydraulic oil circuit through the solenoid valve to raise the rake frame.

[0037] If the state change requirement of the discharge port of the target central transmission concentrator is a change requirement, the specific state change requirement of the discharge port of the target central transmission concentrator is obtained. If it is changed from increasing the discharge flow to reducing the discharge flow, the speed of the discharge pump is reduced. If it is changed from reducing the discharge flow to increasing the discharge flow, the speed of the discharge pump is increased.

[0038] The present invention acquires the pressure of the concentrating tank of the target central transmission concentrator and the current status of each changed component part, analyzes the status change requirements of each changed component part of the target central transmission concentrator based on the obtained pressure of the concentrating tank of the target central transmission concentrator, and changes the status thereof. The adjustment requirements of the process flow of the target central transmission concentrator are analyzed according to the detected pressure of the concentrating tank of the target central transmission concentrator, which is beneficial to accurate and convenient operation and real-time adjustment, and is also beneficial to preventing the occurrence of pressure rake or leakage accidents of the target central transmission concentrator.

[0039] The pressure analysis module is used to obtain the pressure of the concentrator tank of the target central transmission concentrator detected each time during the monitoring time period, and analyze the pressure abnormality evaluation of the concentrator tank of the target central transmission concentrator. If it is a pressure abnormality, the operation data analysis module is executed, otherwise, the pressure analysis module is executed.

[0040] As a preferred feasibility example, the pressure anomaly evaluation of the concentrator tank of the target central transmission concentrator includes: extracting the pressure of the concentrator tank of the target central transmission concentrator detected during each monitoring period; ,in , is the number of each test, is the number of tests, based on which the mean pressure of the concentrator tank of the target central transmission concentrator during the monitoring period is determined and the standard deviation of the concentrator pressure of the target central drive concentrator during the monitoring period , analyze the pressure anomaly evaluation coefficient of the concentrator tank of the target central transmission concentrator ,in is the allowable difference between the set target central transmission concentrator pressure and the standard deviation of the concentrator pressure, is a natural constant.

[0041] It should be noted that the units of the concentrator tank pressure of the target central transmission concentrator detected during the monitoring time period and the standard deviation of the concentrator tank pressure of the target central transmission concentrator during the monitoring time period are both volts, and subtracting them helps to identify the pressure values ​​of each detection that significantly deviates from the normal range in the concentrator tank pressure of the target central transmission concentrator during the monitoring time period, which helps to promptly discover abnormal conditions in the concentrator tank pressure of the target central transmission concentrator.

[0042] The pressure anomaly evaluation coefficient of the concentrator tank of the target central transmission concentrator is compared with the set pressure anomaly evaluation coefficient threshold. If the pressure anomaly evaluation coefficient of the concentrator tank of the target central transmission concentrator is greater than or equal to the pressure anomaly evaluation coefficient threshold, the pressure anomaly evaluation of the concentrator tank of the target central transmission concentrator is recorded as pressure anomaly.

[0043] The present invention analyzes the pressure anomaly evaluation of the concentrator tank of the target central transmission concentrator. If it is a pressure anomaly, the cause of the pressure anomaly is further analyzed, which helps to timely discover and deal with the pressure anomaly, avoids extended downtime due to equipment failure, improves production efficiency, and reduces production costs.

[0044] The operation data analysis module is used to record the components associated with the pressure of the concentrator tank in the target central transmission concentrator as the designated components of the target central transmission concentrator, obtain the operation data of the designated components of the target central transmission concentrator, and analyze the operation conditions of the designated components of the target central transmission concentrator, wherein the designated components include a scraper blade, a scraper arm, a central rotating support, an overflow weir plate and a flow stabilizing cylinder.

[0045] As a preferred feasibility example, the operating data of the scraper blade of the target central transmission concentrator includes the degree of deformation and the width of the gap between the scraper blade and the pool bottom.

[0046] It should be further explained that the reason why the deformation degree and the gap width between the scraper and the bottom of the pool are used as the operating data of the scraper of the target center transmission thickener is: (1) The deformation of the scraper will directly affect its scraping efficiency. If the scraper is deformed, it may cause the contact area between it and the bottom of the pool to decrease, thereby reducing the scraping effect, which will cause the sludge in the thickening tank to fail to be scraped off in time, and thus accumulate in the pool. The accumulation of sludge will increase the concentration of solid particles in the thickening tank, thereby increasing the pressure of the thickening tank.

[0047] (2) The gap width between the scraper and the pool bottom is one of the key factors affecting the scraping effect. If the gap is too large, the resistance of the scraper to scrape the pool bottom will increase, and the concentration of solid particles in the thickening tank will increase, thereby increasing the pressure of the thickening tank. If the gap is too small, the friction between the scraper and the pool bottom may be too large, and the excessive friction may also cause the sludge in the thickening tank to be over-stirred, forming a vortex, thereby increasing the pressure of the thickening tank.

[0048] It should be further explained that the specific method for obtaining the deformation degree of the scraper blade of the target central transmission concentrator is as follows: strain gauges are arranged at various key positions on the scraper blade of the target central transmission concentrator, and then the strains at various key positions on the scraper blade of the target central transmission concentrator are measured according to the arranged strain gauges, and the key positions on the scraper blade of the target central transmission concentrator with the maximum strain are screened out and recorded as the marked key positions of the scraper blade of the target central transmission concentrator, and then according to the analysis formula Obtain the deformation of the scraper blade of the target center drive concentrator ,in The strain at the key position of the scraper blade of the target center drive thickener is marked, The maximum strain of the scraper blade of the target center drive thickener during operation is extracted from the database.

[0049] The specific method for obtaining the width of the gap between the scraper of the target central transmission thickener and the pool bottom is: using the deployed laser rangefinder to directly measure the width of the gap between each measuring point of the scraper of the target central transmission thickener and the pool bottom, selecting the scraper measuring point of the target central transmission thickener with the largest gap width between the largest measuring point and the pool bottom, and recording it as the scraper marked measuring point of the target central transmission thickener, and recording the gap width between the scraper marked measuring point of the target central transmission thickener and the pool bottom as the scraper and pool bottom gap width of the target central transmission thickener.

[0050] The operating data of the scraper arm of the target center transmission concentrator includes operating curvature and operating speed.

[0051] It should be further explained that the reasons for using the operating curvature and operating speed as the operating data of the scraper arm of the target center drive thickener are: (1) The curvature of the scraper arm will affect its scraping efficiency. When the curvature of the scraper arm is too large, the contact area between the scraper arm and the bottom of the pool will be reduced, resulting in incomplete scraping and sludge accumulation at the bottom of the pool, which in turn increases the pressure of the thickening tank.

[0052] (2) The speed of the scraper arm directly affects the scraping efficiency. Too fast speed may lead to incomplete scraping, because the scraper arm stays at the bottom of the pool for too short a time and cannot fully scrape the sludge. Too slow speed may cause the sludge to accumulate at the bottom of the pool for too long, increasing the pressure of the thickening tank. And when the scraper arm runs at a faster speed, it may generate a greater fluid stirring force, causing greater fluctuations and vortices in the fluid in the thickening tank, thereby increasing the pressure fluctuation of the thickening tank.

[0053] It should be further explained that the specific method for obtaining the running curvature of the scraper arm of the target center transmission concentrator is: various laser rangefinders are arranged around the target center transmission concentrator to aim at the corresponding key parts on the scraper arm of the target center transmission concentrator, so as to directly measure the distance length between each key part on the scraper arm of the target center transmission concentrator and its corresponding laser rangefinder when it is stationary by using the arranged laser rangefinders , and the distance between each key part of the scraper arm of the target center transmission concentrator and its corresponding laser rangefinder during movement ,in , The key parts of the scraper arm are numbered. The number of key parts on the scraper arm, and the running curvature of the scraper arm of the target center drive concentrator are analyzed .

[0054] The specific method for obtaining the running speed of the scraper arm of the target central transmission concentrator is: using the arranged speed sensor to directly measure the running speed of the scraper arm of the target central transmission concentrator.

[0055] The operation data of the central rotating support of the target central transmission concentrator include operation smoothness and center position offset distance.

[0056] It should be further explained that the reasons for using the running smoothness and the center position offset distance as the running data of the center rotating support of the target center transmission concentrator are: (1) The running smoothness of the center rotating support is directly related to the mechanical efficiency of the concentrator. When the center rotating support runs smoothly, it can reduce friction and resistance, thereby improving the mechanical efficiency of the concentrator, helping to reduce the energy consumption of the equipment, and thus reducing the pressure fluctuations in the concentrator tank. And when the support runs smoothly, it can maintain the stable flow of the fluid in the concentrator tank, reduce the formation of eddies and turbulence, help reduce the pressure of the concentrator tank, and improve the concentrating effect.

[0057] (2) The center position offset distance of the center drive thickener will affect the scraping efficiency of the scraper arm. If the center position offset is too large, the scraper arm may not be able to completely cover the bottom of the thickening tank, causing sludge to accumulate at the bottom of the tank, thereby increasing the pressure of the thickening tank.

[0058] It should be further explained that the specific method for obtaining the running smoothness of the central rotating support of the target central transmission concentrator is: using the deployed torque sensor to measure the torque of the central rotating support of the target central transmission concentrator during each detection within the set monitoring time period. ,in , is the number of each test, Analyze the running smoothness of the central rotating support of the target central transmission concentrator for the number of tests ,in The permissible torque deviation value of the central rotating support of the set target center transmission concentrator.

[0059] The specific method for obtaining the center position offset distance of the central rotating support of the target center transmission concentrator is: two measuring units of the laser centering instrument are respectively installed at the two ends of the central rotating support of the target center transmission concentrator, and then the center position offset distance of the central rotating support of the target center transmission concentrator is directly measured by using the arranged laser centering instrument.

[0060] The operating data of the overflow weir plate of the target central drive concentrator includes levelness and clogging presence index.

[0061] It should be further explained that the reason for using the horizontality and the clogging existence index as the operating data of the overflow weir of the target center transmission thickener is: (1) The overflow weir is a key component for controlling the water surface elevation and uniform distribution of water flow in the thickener. When the overflow weir is not horizontal, it may cause the water flow to overflow at a certain circumferential angle, resulting in uneven distribution of materials in the tank body, thereby increasing the pressure of the thickening tank.

[0062] (2) The clogging existence index is an important indicator to measure the degree of clogging of the overflow weir. When the overflow weir is severely clogged, the water flow will be blocked, which will increase the pressure of the concentration tank and may even cause equipment failure.

[0063] It needs to be further explained that the specific method for obtaining the horizontality of the overflow weir plate of the target central transmission concentrator is: directly measuring the horizontality of the overflow weir plate of the target central transmission concentrator by using a deployed laser level.

[0064] The specific method for obtaining the blockage existence index of the overflow weir plate of the target central transmission concentrator is as follows: using a deployed high-definition camera to photograph the overflow weir plate of the target central transmission concentrator to obtain a picture of the overflow weir plate of the target central transmission concentrator, and using image processing software to analyze whether the overflow weir plate of the target central transmission concentrator is blocked. If the overflow weir plate of the target central transmission concentrator is blocked, the blockage existence index of the overflow weir plate of the target central transmission concentrator is recorded as 1; if the overflow weir plate of the target central transmission concentrator is not blocked, the blockage existence index of the overflow weir plate of the target central transmission concentrator is recorded as 0.

[0065] The operating data of the stabilizing drum of the target central drive concentrator includes the presence of blockage.

[0066] It needs to be further explained that the reason for taking the existence of blockage as the operating data of the flow stabilizer of the target central transmission concentrator is that a blocked flow stabilizer will restrict the normal flow of water, causing the water level in the concentrator tank to rise, thereby increasing the pressure in the concentrator tank.

[0067] It needs to be further explained that the specific method of obtaining the existence of blockage of the steady flow cylinder of the target center transmission concentrator is: use the deployed high-definition camera to shoot the steady flow cylinder of the target center transmission concentrator to obtain a picture of the steady flow cylinder of the target center transmission concentrator, and use image processing software to analyze whether there is blockage in the steady flow cylinder of the target center transmission concentrator; if there is blockage in the steady flow cylinder of the target center transmission concentrator, the existence of blockage in the steady flow cylinder of the target center transmission concentrator is recorded as existing; if there is no blockage in the steady flow cylinder of the target center transmission concentrator, the existence of blockage in the steady flow cylinder of the target center transmission concentrator is recorded as not existing.

[0068] As a preferred feasibility example, in the process of analyzing the operation of the scraper blade, scraper arm, central rotating support and overflow weir plate of the target central transmission thickener, it is necessary to construct the operation abnormality evaluation index of the scraper blade, scraper arm, central rotating support and overflow weir plate of the target central transmission thickener. The specific analysis method includes: extracting the deformation degree of the scraper blade of the target central transmission thickener and the gap width between the scraper and the pool bottom Based on this, the abnormal operation evaluation index of the scraper of the target central transmission concentrator is analyzed.

[0069] It should be further explained that the specific analysis method of the abnormal operation evaluation index of the scraper of the target central transmission concentrator is: according to the analysis formula Obtain the abnormal operation evaluation index of the scraper of the target central transmission thickener ,in is the standard gap width between the scraper and the pool bottom of the target central transmission thickener extracted from the database, It is the allowable difference between the set width of the gap between the scraper and the pool bottom and the standard width of the gap between the scraper and the pool bottom.

[0070] It should be noted that the allowable difference between the set width of the gap between the scraper and the pool bottom and the standard width of the gap between the scraper and the pool bottom can be 0.01 meters, which means that a deviation of one percent is allowed between the width of the gap between the scraper and the pool bottom and the standard width of the gap between the scraper and the pool bottom.

[0071] Extraction target center drive thickener scraper arm running curvature and running speed , based on which the abnormal operation evaluation indicators of the scraper arm of the target central transmission concentrator are analyzed.

[0072] It should be further explained that the specific analysis method of the abnormal operation evaluation index of the scraper arm of the target central transmission concentrator is: according to the analysis formula Obtain the abnormal operation evaluation index of the scraper arm of the target center transmission concentrator ,in The standard operating speed of the scraper arm of the target central drive thickener extracted from the database, The permissible difference between the set operating speed and the standard operating speed.

[0073] It should be noted that the allowable difference between the set running speed and the standard running speed is 0.01 meters per second, which means that a deviation of one percent is allowed between the running speed and the standard running speed.

[0074] Extraction target center drive concentrator center rotating support running smoothness Distance from center position Based on this, the operation abnormality evaluation indicators of the central rotating support of the target central transmission concentrator are analyzed.

[0075] It should be further explained that the analysis method of the abnormal operation evaluation index of the central rotating support of the target central transmission concentrator is: according to the analysis formula Obtain the abnormal operation evaluation index of the central rotating support of the target central transmission concentrator ,in is a minimum constant set to prevent the denominator from being 0. It is the permissible center position offset distance under the condition that the normal operation of the center rotating support of the target center transmission concentrator is not affected.

[0076] Extraction target center drive thickener overflow weir level and the congestion presence index , based on which the abnormal operation evaluation indexes of the overflow weir plate of the target central transmission concentrator are analyzed.

[0077] It should be further explained that the analysis method of the abnormal operation evaluation index of the overflow weir plate of the target central transmission concentrator is: according to the analysis formula Obtain the abnormal operation evaluation index of the overflow weir of the target central transmission concentrator , It is a minimum constant set to prevent the denominator from being zero.

[0078] As a preferred feasibility example, the operating conditions of the scraper blade, scraper arm, central rotating support and overflow weir of the target central transmission concentrator are specifically obtained in the following manner: comparing the operating abnormality evaluation index of the scraper blade of the target central transmission concentrator with the set operating abnormality evaluation index threshold of the scraper blade; if the operating abnormality evaluation index of the scraper blade of the target central transmission concentrator is greater than the operating abnormality evaluation index threshold of the scraper blade, the operating condition of the scraper blade of the target central transmission concentrator is recorded as operating abnormality.

[0079] Similarly, the operating conditions of the scraper arm, central rotating support and overflow weir plate of the target central transmission concentrator can be obtained.
