Description

Technical Field

[0001] This invention belongs to the field of coal testing technology, specifically an automated coal testing system and method based on intelligent control and analysis technology. Background Technology

[0002] In coal testing, sample preparation is the starting point of the entire process. Based on their experience and following established operating procedures, staff process the collected coal samples, using operations such as crushing and reducing their size to prepare samples that meet testing requirements. After sample preparation, these samples are placed in a pneumatic transfer station, where they are transported to the laboratory's pneumatic transfer receiving station using the powerful thrust generated by high-pressure gas.

[0003] Once the samples arrive at the laboratory, they are manually retrieved from the receiving station. Staff then manually distribute the samples to the corresponding testing equipment according to the testing tasks assigned by the LIMS (Laboratory Information Management System). For example, a sulfur analyzer is used to detect the sulfur content of coal, a calorimeter to measure the calorific value of coal, and an industrial analyzer to analyze indicators such as moisture and ash content. During the testing process, staff must constantly monitor the operating status of the equipment and manually record data at each testing stage. After all testing items are completed, staff manually enter the test results back into the LIMS system for subsequent data storage, analysis, and sharing, providing a reference for coal quality assessment, transaction pricing, and usage.

[0004] However, existing technologies have the following drawbacks:

[0005] Manual operation is inefficient. From sample transfer and distribution after sample preparation to the recording and entry of test data, the entire process involves a large amount of manual operation.

[0006] Human error is significant. During the sampling and delivery process, due to differences in the operating methods and habits of different staff, samples may be contaminated or damaged to varying degrees, which can affect the accuracy of the test results.

[0007] Poor information flow and a manual operation mode result in a lack of real-time and effective information exchange between various stages. Testing personnel may not be aware of the arrival of new samples in a timely manner, leading to equipment downtime and reduced equipment utilization.

[0008] The work is labor-intensive and prone to errors. Staff members need to frequently travel between different equipment and areas, operating testing equipment and recording and entering data, which is quite labor-intensive. Summary of the Invention

[0019] In a preferred embodiment, the sample inlet of the sulfur testing unit is connected to the sample outlet pipelines of water-ash testing unit one, water-ash testing unit two, and water-ash testing unit three via a switching valve, and the switching valve is controlled by the main control system to switch the path; the carrier gas inlet of the sulfur testing unit is connected to a nitrogen cylinder, and the carrier gas outlet is connected to a waste gas treatment device.

[0020] In a preferred embodiment, the outlet of the calorimeter unit water tank is branched into two branches through the main pipeline, which are respectively connected to the cooling water inlet of the first calorimeter unit host and the cooling water inlet of the second calorimeter unit host; the cooling water outlets of the first calorimeter unit host and the second calorimeter unit host are combined and then connected back to the return outlet of the calorimeter unit water tank.

[0025] (1). The system is started and the ABB six-axis robot places the corresponding crucibles for calorific value, moisture, ash and total sulfur from the crucible rack onto the rotating sample disks of the precision sampling device 1 and the precision sampling device 2 respectively.

[0026] (2). The sample bottles to be tested are automatically pushed into the sample bottle transfer mechanism in the closed test room one by one and the detailed information of the sample bottle RFID is read and uploaded to the system. The two-axis robot grabs the sample bottle from the internal buffer platform according to the system rhythm and places it in the sample bottle station of the precision sample addition device. The bottle opening device opens the sample bottle cap. The metal bottle cap is replaced. The sample is mixed. The precision sample addition device rotates to rotate the corresponding calorific value, moisture, ash and total sulfur crucibles to the weighing position and lowers the turntable so that the crucible is lifted by the weighing pan of the built-in 1 / 10,000 gram precision balance. The sample dynamically enters the crucible. The system reads the balance weight data in real time. When the requirement is met, the sample addition stops. The sample pan rises to the normal position and rotates to the next crucible position. The above process is repeated until all crucibles corresponding to a sample are added. The two-axis robot replaces and closes the sample bottle cap. The sample bottle is sent back to the internal buffer device and sent out of the test room through the sample bottle transfer mechanism and placed on the external sample bottle disposal platform. The precision sample addition device cleans the sample bottle cap and dries it with high-pressure airflow to facilitate the allocation of new samples.

[0027] (3). The ABB six-axis robot picks up the calorific value, moisture, ash and total sulfur crucibles of the samples added on the precision sampling device and delivers them to the temporary sample trays of the corresponding analytical instruments.

[0028] (4). Each analytical instrument sends the sample crucible on the temporary sample tray into the internal analysis chamber for testing according to the instrument's standard analysis procedure. The sulfur analyzer will automatically add tungsten trioxide to the sample.

[0029] (5). The test crucibles will be returned to the empty crucible position of the temporary sample tray by the analytical instrument. The full sulfur crucibles will be cleaned of combustion residue by the machine. The calorific value crucibles and water ash crucibles will be put back into the crucible rack by the robot. The residue treatment device on the crucible rack will automatically clean the ash in the crucibles. The cleaned crucibles will be recycled.

[0030] (6) The test results of each analytical instrument are automatically summarized and organized in the main control system using the sample number as an index to form raw data, and then used for subsequent laboratory management.

[0031] The system includes a sample receiving and sorting module, an automated testing module, an intelligent control and data analysis module, and an integrated control terminal.

[0032] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0033] 1. In this invention, sample sorting and allocation are more efficient and accurate. The intelligent sample sorting technology can quickly and accurately allocate samples to the corresponding automated testing equipment, significantly improving sorting efficiency, reducing waiting time, and enhancing the overall efficiency of the testing process compared to existing technologies. Traditional manual sample sorting can easily lead to backlog when there are many samples, prolonging the testing cycle. However, the intelligent sorting system of this patent can dynamically adjust the sorting strategy according to equipment status and workload, achieving rapid and reasonable sample allocation. For example, when processing a large number of coal samples, the intelligent sorting system can complete sample allocation within minutes, while manual sorting may take several hours, greatly shortening the start time of the testing process.

[0034] 2. In this invention, equipment collaboration and utilization are significantly improved. All automated testing equipment works collaboratively under the unified scheduling of the system, and samples are rationally allocated according to equipment status and workload, thereby improving equipment utilization and avoiding equipment idleness and overuse. In existing technologies, testing personnel may not be aware of the arrival of new samples in a timely manner, leading to equipment idleness; or, when tasks are not rationally allocated, some equipment may be overused, affecting equipment lifespan. This patent achieves efficient equipment utilization through unified system scheduling.

[0035] 3. In this invention, data processing and analysis are more accurate and reliable. Automated data acquisition and intelligent data processing and analysis methods avoid errors caused by manual intervention, improving data accuracy and the reliability of analysis results, and providing a more precise basis for coal quality assessment. When recording and entering data manually, errors are easily made due to negligence, fatigue, or other factors, affecting data reliability. This patent ensures data accuracy and reliability through automated data acquisition and intelligent analysis. For example, when testing the total sulfur content of coal, automated equipment can accurately measure and automatically record data, avoiding errors that may occur with manual recording, making the test results more accurate and reliable.

[0036] 4. The integrated management system in this invention offers significant advantages. The integrated control terminal enables centralized monitoring and remote control of the entire testing process, allowing operators to promptly grasp the system's operational status, quickly resolve issues, and improve system management efficiency and stability. In existing technologies, real-time and effective information exchange between different stages is lacking, and errors during data entry are difficult to detect and correct in a timely manner. This patented integrated control terminal solves these problems through a visual interface and remote control functionality, improving system management efficiency and stability. For example, operators can view the real-time operating status of all equipment through the integrated control terminal. If equipment malfunctions or data anomalies are detected, timely action can be taken to prevent the problem from escalating and ensure the smooth operation of the testing work.

[0057] An automated coal testing method based on intelligent control and analysis technology, applied to the aforementioned automated coal testing system based on intelligent control and analysis technology, specifically includes the following steps:

[0058] (1). When the system is started, the ABB six-axis robot places the corresponding crucibles for calorific value, moisture, ash and total sulfur from the crucible rack onto the rotating sample disks of the precision sample loading device 1 and the precision sample loading device 2 respectively.

[0059] (2) The system automatically pushes the sample bottles to be tested one by one into the sample bottle transfer mechanism in the closed test room and reads the detailed information of the sample bottle RFID and uploads it to the system. The two-axis robot picks up the sample bottles from the internal buffer platform according to the system rhythm and places them in the sample bottle station of the precision sample dispensing device. The bottle opening device opens the sample bottle cap. The metal bottle cap is replaced. The sample is mixed. The precision sample dispensing device rotates to rotate the corresponding calorific value, moisture, ash, and total sulfur crucibles to the weighing position and lowers the turntable so that the crucible is lifted by the weighing pan of the built-in 0.01g precision balance. The sample dynamically enters the crucible, and the system reads the balance weight data in real time. When the requirement is met, the sample dispensing stops.

[0064] The system includes a sample receiving and sorting module, an automated testing module, an intelligent control and data analysis module, and an integrated control terminal.

[0065] From the above, we can conclude that:

[0066] In this invention, sample sorting and allocation are more efficient and precise. The intelligent sample sorting technology can quickly and accurately allocate samples to the corresponding automated testing equipment, significantly improving sorting efficiency, reducing waiting time, and enhancing the overall efficiency of the testing process compared to existing technologies. Traditional manual sample sorting can easily lead to backlogs and prolong the testing cycle when there are many samples.

The sample bottles to be tested are automatically pushed into the sample bottle transfer mechanism in the closed test room one by one and the detailed information of the sample bottle RFID information is read and uploaded to the system. The two-axis robot grabs the sample bottle from the internal buffer platform according to the system rhythm and places it in the sample bottle station of the precision sample addition device. The bottle opening device opens the sample bottle cap. The metal bottle cap is replaced. The sample is mixed. The precision sample addition device rotates to rotate the corresponding calorific value, moisture, ash and total sulfur crucibles to the weighing position and lowers the turntable so that the crucible is lifted by the weighing pan of the built-in 1 / 10,000 gram precision balance. The sample dynamically enters the crucible. The system reads the balance weight data in real time. When the requirement is met, the sample addition stops. The sample pan rises to the normal position and rotates to the next crucible position. The above process is repeated until all crucibles corresponding to a sample are added. The two-axis robot replaces and closes the sample bottle cap. The sample bottle is sent back to the internal buffer device and sent out of the test room through the sample bottle transfer mechanism and placed on the external sample bottle disposal platform. The precision sample addition device cleans the sample bottle cap and dries it with high-pressure airflow to facilitate the allocation of new samples. (3). The ABB six-axis robot picks up the calorific value, moisture, ash and total sulfur crucibles of the samples added on the precision sampling device and delivers them to the temporary sample trays of the corresponding analytical instruments. (4). Each analytical instrument sends the sample crucible on the temporary sample tray into the internal analysis chamber for testing according to the instrument's standard analysis procedure. The sulfur analyzer will automatically add tungsten trioxide to the sample. (5). The test crucibles will be returned to the empty crucible position of the temporary sample tray by the analytical instrument. The full sulfur crucibles will be cleaned of combustion residue by the machine. The calorific value crucibles and water ash crucibles will be put back into the crucible rack by the robot. The residue treatment device on the crucible rack will automatically clean the ash in the crucibles. The cleaned crucibles will be recycled. (6) The test results of each analytical instrument are automatically summarized and organized in the main control system using the sample number as an index to form raw data, and then used for subsequent laboratory management. The system includes a sample receiving and sorting module, an automated testing module, an intelligent control and data analysis module, and an integrated control terminal.
