[0036] As Figure 5 And Figure 6 Some size examples are given in mm, which will be further described below.

[0037] In the continuous conveying of raw materials, the composition of the ore needs to be detected in real time, including 13 components such as total aluminum and effective aluminum. The ore composition analyzer will form a 40*40cm irradiation range on the surface of the belt, and the starting detection will be sequentially arranged according to the conveying direction of the ore bulk on the conveying belt (belt). The analyzer and its detection system include a timing origin unit, an energy spectrum detection unit, a belt speed measurement unit, a remote vision detection unit, a near-infrared NIR detection unit, and a belt pressure control detection unit, etc.

[0038] The remote vision detection unit (camera unit) is a camera that detects the granularity, accumulation degree, and inclusions of the ore bulk in the conveying state of the belt to prevent abnormal situations.

[0039] The belt pressure control detection unit (pressure detection unit) is a pressure sensor group that obtains real-time data of the pressure of the ore spread on the belt to realize continuous detection of the homogenization effect of the ore.

[0040] In the analyzer, the near-infrared NIR detection unit detects the real-time randomness of various taste components of the ore bulk in the conveying state of the belt. The energy spectrum detection unit detects the signal intensity of the halogen lamp irradiation in the conveying state, and automatically adjusts the irradiation power according to the signal intensity. The timing origin unit obtains the starting point and ending point of the online measurement as the critical point of the measurement within a certain time range, and also as the starting signal of the bulb heating. A purge control unit can also be designed to periodically purge the dust on the bulb and link to self-correct the deviation value.

[0041] Belt speed measurement unit (speed detection unit), for speed sensor, with belt pressure control detection unit linkage, according to the pressure control state automatically adjust the speed of the belt.

[0042] In order to improve the belt raw material quantity detection accuracy, can also be designed photoelectric control metering unit, for flow speed sensor, detection flow transmission state of the instantaneous flow of bulk ore, realize the accurate measurement of weight and volume accurate feeding quantity.

[0043] Also can be designed mechanical screen vibration control unit, for the vibrator connected with the control cabinet, which is arranged on the moving frame, according to fixed time interval or ore quantity, automatic vibration screen moving guide rail and other dust and other impurities, reduce the failure rate, prevent jam.

[0044] The multi-belt coordination system will automatically detect which belt is running during continuous ore conveying, and issue instructions to the ore analyzer to automatically move above the belt, and give an early warning to the nearby maintenance personnel and other personnel to evacuate quickly. After reaching the position, the belt pressure and voltage and current signals will be monitored in real time. If the voltage and current signals meet the analyzer's starting requirements, the analyzer will enter the moving state and start the detection system to enter the working state, including the analyzer preheating start preparation, after starting operation, the belt speed sensor will start the linkage of the above two electric signal three-in-one to meet the requirements and issue the instruction to enter the preheating state; Send start working instruction to visual control unit and timing origin unit, mark the time position origin of ore measurement, mark the analyzer starting detection unit entering working state time point; When the belt stops, restarts, the ore flow breaks, recirculates, and empties, the ore flow speed sensor and current measurement sensor will restart the analyzer to enter the preheating state and the working state. During the emptying process of the ore on the belt, the analyzer will immediately exit the working state and prompt that the period detection is over.

[0045] Among them, the analyzer, control cabinet, camera unit, pressure detection unit and speed detection unit and other components and their connection control are prior art, which can be realized by connecting standard power data line through factory configuration, and will not be described here. The analyzer and its detection system can also realize the following functions.

[0046] After obtaining the working state point signal, the remote machine vision detection unit starts to capture high-definition photos of various stacking states of the ore on the surface of the transmission belt at a frequency of 1 second, while ensuring the safety around the belt.

[0047] After obtaining the ore stacking height and pressure, current signal data, the near-infrared NIR detection unit adjusts the power of the irradiation light source according to the measured pressure and current starting energy spectrum detection power supply.

[0048] When the entering working state is obtained, the timing origin unit and the near-infrared NIR detection signal collection are synchronized to realize the corresponding association of data and full composition detection data.

[0049] After the point signal of obtaining the entering working state is obtained, the mechanical vibrating screen unit vibrates and dusts the analyzer and the moving slide rail according to the time interval of the sampling timing, so as to ensure the cleaning of the equipment.

[0050] When the subsequent detection unit exits the working state after the random marking, the blowing control unit will indirectly clean the dust of the bulb.

[0051] According to the apparent height of the ore, the pressure measurement, the flow velocity measurement, the preheating detection system, the start detection, the interruption detection, the restart detection, the replacement of the belt transmission, the replacement of the control concentration, the end detection, and the stop of the detection system, the data record is reported, the time report, and the day report.

[0052] According to the composition record, the data processing self-learning algorithm of the flow detection is adjusted.

[0053] The multi-element detection data is separately superimposed and processed, and the leaching feed control processing is associated.

[0054] The analyzer in the ore composition real-time online detection method, the specific steps are as follows:

[0055] First step: judge the position of the ore through the analyzer, and make sure that the ore is completely below the analyzer;

[0056] Second step: judge the transmission pressure and current of the ore and the stacking height on the belt;

[0057] Third step: process the detection data collected by the analyzer bulb, output the overall composition content and apparent index of the ore per minute, and output and record the composition results in a single time range in real time, and associate the traceable information.

[0058] As described above, the system solves the problems that the ore grade on the belt cannot be monitored and cannot be linked, and there is no random sampling process. Through the composite measurement and comparison of the ore element content and the apparent physical characteristics by multiple technical units, the real-time monitoring is realized. The belt measurement can be switched according to the running conditions of the A and B belts, and the real-time detection of the chemical composition of the ore material on the belt is realized. When the belt is stopped, idling, or has little material, the data detection is automatically stopped. The system measures 148 groups of data per minute, and the measurement results are more representative and timely, which has more precise guiding significance for the production process control.

[0059] There are also advantages as follows: high frequency scanning sample high coverage, online real-time analysis high stability, multi-unit detection + large sample record comparison self-learning correction avoid abnormal data and variance adjustment + real-time detection and non-associated data element comparison continuous approach static chemical analysis detection precision. No need to take sample manually, reduce labor intensity; no physical sample physical detection, no sample chemical analysis, improve detection efficiency, mass original data storage, retrieval convenient and accurate, data comprehensive storage persistence.
