Description

Technical Field

[0001] The invention relates to the field of steel chemical detection and analysis, and in particular to an automatic lime activity detection and data acquisition system. Background Art

[0002] Steel companies use a large amount of various types of lime in steel smelting, and the quality of lime is closely related to production. In order to ensure production quality, reduce procurement costs and improve detection efficiency, the accuracy, timeliness and traceability of the test results are very important. The existing lime activity detection methods have the following problems:

[0003] 1. The activity test of lime samples was initially conducted by manual analysis and titration, which was inefficient. The purchased automatic activity analyzer was not fully functional and could only analyze some fine powder samples. In the actual testing of various types of samples used in production, such as active lime (bottom ash), lime powder for sintering desulfurization, lime powder for sintering desulfurization, refined lime, self-produced lime and other types of lime with large particle size, it was found that most edge samples had sedimentation, resulting in inaccurate test results and large errors, which could not meet production needs. 2. The test procedure was set up unreasonably, with significant deviations from the standard requirements (YB / T105-2014 "Metallurgical Lime Physical Test Methods"). Automatic titration was started before the experimental conditions were met, resulting in early reaction and poor accuracy of the test results. 3. The previous weighing data and test data could not be automatically transmitted, so the test data could not be traced, and the risk of error was high. Since hydrochloric acid reagent was used in the activity test, the titration equipment used a metal shell, which was prone to corrosion.

[0004] Therefore, it is necessary to develop a new type of automatic detection system for lime activity and data acquisition to overcome the above problems. Summary of the invention

[0005] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides an automatic detection system for lime activity and data acquisition, improves the existing lime activity detector and its program, meets the requirements of automatic detection of activity of various types of lime powder, improves the traceability of detection data, data accuracy, and increases the service life of the equipment.

[0006] Technical solution: The present invention provides an automatic lime activity detection and data acquisition system, which is characterized by comprising a titration device, a stirring device, a control console, a PDA, an electronic balance, a barcode scanner and a computer; the control console, the PDA, the electronic balance and the barcode scanner are respectively connected to the computer, and the control console is provided with a titration device and a stirring device.

[0007] The bottom of the stirring device includes a power sheet with a thickness of ≥25 mm and a straight rotor with a length of 8 cm.

[0008] Wherein, the control console is provided with a software program to cancel the "stirring acceleration time 10s" set in the experimental time.

[0009] Wherein, the metal shell of the console is covered with an acid- and alkali-proof film, or an acid- and alkali-proof plastic shell is used.

[0010] The PDA has built-in acquisition software, which is face recognition and sample association software, and the PDA interacts with computer data.

[0011] The computer has built-in data acquisition software, which is connected to an electronic balance and a barcode scanner.

[0012] Wherein, the data of the control console, electronic balance and barcode scanner are uploaded to the computer.

[0013] When testing samples, the staff opens the weighing data collection software in the computer, uses a barcode scanner to scan the sample information, and opens the PAD to perform facial recognition of the tester and sample recognition. Then, the electronic balance is used to weigh the sample. After weighing, click OK, and the weighing information is automatically uploaded. Then, the lime activity detection equipment to be used is selected in the software, and the weighed sample is placed in the selected equipment for testing. After the test is completed, the data is automatically uploaded to the computer.

[0014] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention improves the existing lime activity detector and its program, and solves the problems of the same type of equipment on the market, such as the single type of test sample, edge sample deposition in the container, uneven stirring force, low accuracy, and data traceability. It improves the detection efficiency and accuracy of stone activity and reduces the risk of errors. At the same time, since the casing of the existing lime automatic detection equipment on the market is metal and easily corroded, it is now replaced with a plastic casing or a waterproof film is used to stick to the outside of the equipment, which extends the service life of the equipment. It can be applied to the activity detection of various types of lime. In addition to sintering lime, it can be widely used for large-particle lime types such as active lime (bottom ash), lime powder for sintering desulfurization, lime powder for sintering desulfurization, refined lime, and self-produced lime.

[0018] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The automatic lime activity detection and data acquisition system of the present invention comprises a titration device 1, a stirring device 2, a control console 3, a PDA, an electronic balance, a barcode scanning gun and a computer; the control console 3, the PDA, the electronic balance and the barcode scanning gun are respectively connected to the computer, and the titration device 1 and the stirring device 2 are arranged on the control console 3.

[0020] The bottom of the stirring device 2 of the present invention includes a power sheet with a thickness of ≥25mm and a straight rotor with a length of 8cm. The console 3 is provided with a software program to eliminate the "stirring acceleration time 10s" set in the experimental time. The metal shell of the console 3 is affixed with an acid- and alkali-proof film or an acid- and alkali-proof plastic shell. The PDA has built-in acquisition software, which is a face recognition and sample association software, and the PDA interacts with the computer data. The computer has built-in data acquisition software, which is connected to the electronic balance and the barcode scanner. The data of the console 3, the electronic balance, and the barcode scanner are uploaded to the computer.

[0021] When testing samples, the staff opens the weighing data collection software in the computer, uses a barcode scanner to scan the sample information, and opens the PAD to recognize the tester's face and sample, and then uses an electronic balance to weigh the sample. After weighing, click OK, and the weighing information is automatically uploaded. Then, the lime activity test equipment to be used is selected in the software, and the weighed sample is placed in the selected equipment for testing. After the test is completed, the data is automatically uploaded to the computer. The test data cannot be modified and can be traced, reducing the risk of errors.

[0022] The present invention increases the types of lime activity detection by modifying the original lime activity detection equipment, improves the accuracy, timeliness and traceability of data, and prolongs the service life of the equipment. In view of the problem of uneven stirring of the stirring device of the original equipment, experimental data show that the original 4 mm thick power sheet and 5 cm cross rotor are changed to a ≥ 25 mm thick power sheet and 8 cm long straight rotor, which can stir evenly and solve the problem of edge sample deposition, realize the analysis and detection of lime samples of different particle sizes, and meet production needs.

[0023] In order to comply with the standard experimental process, the built-in software program of the console is changed to eliminate the experimental time setting: "Stirring acceleration time 10 seconds". A control panel button is added to the console. Stir first, and then press the start timer after stabilization to meet reasonable conditions and ensure that the laboratory can conduct experiments normally. The accuracy and stability of the data are significantly improved. Combined with PDA, automatic data transmission and traceability are achieved, reducing the risk of errors. The present invention solves the problem of inaccurate results caused by edge sample deposition in existing activity detectors, and by improving the detection procedure, it meets the requirements of standard YB / T105-204 and realizes automatic transmission of detection data and data traceability. Improve the accuracy, timeliness and traceability of lime activity detection and extend the service life of the equipment.

[0024] Example:

[0025] In this embodiment, the power sheet of the stirrer bottom plate is 25 mm thick, and the straight rotor is 8 cm long, which has strong magnetic force and sufficient power, can stir evenly, and solves the problem of edge sample sedimentation. The console is changed to a plastic shell that is resistant to acid and alkali corrosion.

[0026] Thirteen groups of samples were drawn, and three parallel samples were used. One device was used before and after the improvement, and the experimental results of manual analysis were used as the control group. The error between the equipment and manual data before the improvement exceeded 4%, which did not meet the standard requirements; the test data of the equipment after the improvement met the standard requirements (see Table 1).
