Description

Technical Field

[0002] For fuel analysis, practitioners in the industry have started to study the solution of fully automated testing system. The main implementation method is to use industrial robots to replace people to complete sample sampling, sample weighing, and crucible delivery to various testing equipment. However, the existing fully automated testing system is not truly unmanned. In the process of automatic testing of the system, there are still many links that require continuous human assistance. For example, it is necessary to use manual labor to store sample bottles through manual interfaces and regularly recover sample bottles, sampling spoons, weighing buckets, crucible holders and crucibles. The regularly recovered sample bottles, sampling spoons, weighing buckets, crucible holders and crucibles also need to be manually cleaned. After cleaning, it is necessary to rely on manual labor to regularly add the above components to the testing system. Once the automated testing system requires manual intervention, it is possible that samples are falsified and test results are interfered with by humans. In addition, the recovery, cleaning and addition of the above components also require a certain amount of manpower, which cannot truly liberate labor. Therefore, it is an urgent problem for technicians in this field to provide a set of sample testing systems that can be recycled, efficiently and reliably perform sample testing, do not require manual intervention, and are truly unattended.

[0038] like Figures 1 to 3 As shown, the present invention discloses an unattended sample testing system, comprising a sample bottle processing module 1, an automatic weighing module 2, a crucible storage module 3, a calorimetric module 4, a testing module 5, an automatic crucible cleaning module 6, a robot module 7 and a control module. The sample bottle processing module 1, the automatic weighing module 2, the crucible storage module 3 and the calorimetric module 4 are sequentially arranged in a straight line on one side of the robot module 7, the automatic crucible cleaning module 6 is arranged below the crucible storage module 3, the testing module 5 is arranged on the remaining peripheral sides of the robot module 7, and the control module is used for controlling the operation of each module. The unattended sample testing system of the present invention comprises a sample bottle processing module 1, an automatic weighing module 2, a crucible storage module 3 and a calorimetric module 4 which are arranged in a straight line on one side of a robot module 7, an automatic crucible cleaning module 6 is arranged below the crucible storage module 3, and a testing module 5 is arranged on the remaining sides of the robot module 7. The layout of the system can effectively save space. The sample bottle processing module 1, the automatic weighing module 2, the crucible storage module 3 and the calorimetric module 4 are arranged in a straight line on one side of the robot module 7, which is convenient for the circulation of samples and has reasonable space utilization. By setting up the automatic crucible cleaning module 6, the automatic cleaning of the crucible after the experiment can be met, thereby realizing cyclic testing without manual intervention and truly liberating labor. The automatic crucible cleaning module 6 is arranged below the crucible storage module 3, and the path for the robot module 7 to transfer the crucible before and after the crucible is cleaned is short, with high efficiency, reliability and stability.

[0039] In this embodiment, the test module 5 at least includes a sulfur test module 51, a carbon, hydrogen and nitrogen test module 52, and a water ash test module 53. Multiple test modules 5 are relatively parallel to the sample bottle processing module 1, the automatic weighing module 2, the crucible storage module 3 and the calorimetric module 4 and are arranged on the periphery of the robot module 7; optionally, multiple test modules 5 are arranged around the robot module 7. The test modules 5 are all high-temperature operations, and are relatively independent of the sample bottle processing module 1, the automatic weighing module 2, the crucible storage module 3 and the calorimetric module 4. The impact of the test module 5 on the sample bottle processing module 1, the automatic weighing module 2, the crucible storage module 3 and the calorimetric module 4 can be effectively reduced. When a module of the sample bottle processing module 1, the automatic weighing module 2, the crucible storage module 3 and the calorimetric module 4 fails and needs manual processing, it is convenient for manual maintenance because it is relatively independent from the high-temperature test module 5. Of course, only several common test modules 5 are listed above, and they can be deleted according to actual conditions, such as ash melting test modules, fluorine and chlorine test modules, and total moisture test modules. Each test module 5 can be tested simultaneously without affecting each other.

[0040] In this embodiment, the sample bottle processing module 1 includes a transceiver 11, a sample bottle storage device 12, a sample bottle opening and closing cover device 13, a sample bottle shaking device 14 and a sample bottle transfer device 15. The transceiver 11 is provided with a pneumatic docking port, and the transceiver 11 is used to receive sample bottles transmitted by the pneumatic transmission system; the sample bottle storage device 12 is used to store sample bottles; the sample bottle opening and closing cover device 13 is used to realize the opening and closing of the sample bottles; the sample bottle shaking device 14 is used to realize the mixing of the samples in the sample bottles; the sample bottle transfer device 15 is used to drive the sample bottles to be transferred between the transceiver 11, the sample bottle storage device 12, the sample bottle opening and closing cover device 13, the sample bottle shaking device 14 and the automatic weighing module 2. The transceiver 11 is connected to the pneumatic transmission system and can receive the sample bottles transmitted by the pneumatic transmission system; when the calorimetric module 4 and the test module 5 are both in operation, the sample bottle transfer device 15 can send the sample bottles to the sample bottle storage device 12; when the calorimetric module 4 or the test module 5 is in an idle state, the sample bottle processing module 1 will shake and open the cover of the sample bottle in time, and send it to the automatic weighing module 2 through the sample bottle transfer device 15 for sampling and automatic weighing.

[0041] In this embodiment, the automatic weighing module 2 includes a sampling device 21, a vibrating feeding device, a cleaning device 22 and a lifting balance device 23; the sampling device 21 is used to take out samples from the sample bottle and add the samples to the vibrating feeding device, the vibrating feeding device is close to the lifting balance device 23, and the vibrating feeding device is used to transport the samples to the crucible placed on the lifting balance device 23. The sample bottle processing module 1 cooperates with the automatic weighing module 2 to realize a series of processes such as sample bottle storage - mixing - opening the cover - sampling - weighing - closing the cover - storage for full automatic processing. And the vibrating feeding device can ensure that the sample bottle can be output slowly and finely from the discharge port, and the lifting balance device 23 weighs the sample weight in real time to ensure accurate sample addition.

[0042] In this embodiment, the calorimetric module 4 includes: a calorific value testing device 41, which is used to test the calorific value of the sample in the crucible in the oxygen bomb; a crucible processing device 42, which is used to automatically pull out the oxygen bomb core and automatically take and place the crucible in the oxygen bomb core; an oxygen charging and discharging device 43, which is used to automatically charge or discharge oxygen to the oxygen bomb; an oxygen bomb cleaning and watering device 44, which is used to automatically clean the oxygen bomb body and automatically add a certain amount of water to the inner barrel of the calorific value testing device 41; an oxygen bomb automatic lid opening and closing device 45, which is used to automatically open or close the oxygen bomb cover on the oxygen bomb; an oxygen bomb storage device 46, which is used to store the oxygen bomb; and an oxygen bomb transfer device 47, which is used to transfer the oxygen bomb between various devices. Through the organic cooperation of various devices, the oxygen bomb can be automatically charged and discharged, the lid opened and closed, the crucible automatically taken and placed, the automatic cleaning, and the automatic watering can be realized, and the calorific value test of the sample can be automatically completed, with a high degree of automation. If the calorific value testing device 41 of the calorimetric module 4 is in operation, the oxygen bomb can be temporarily stored in the oxygen bomb storage device 46 after being filled with oxygen; so as to facilitate the reasonable matching of the operation of each device; further, in a preferred embodiment, there are more than two sets of calorific value testing devices 41, and the calorific value testing devices 41 adopt a redundant design. When a single device fails, the system can still operate normally and will not shut down.

[0043] In this embodiment, the crucible processing device 42, the oxygen charging and discharging device 43, the oxygen bomb cleaning and water adding device 44, and the oxygen bomb automatic cover opening and closing device 45 are arranged in a straight line, the calorific value testing device 41 is arranged below each device, and the oxygen bomb transfer device 47 is slidably arranged on one side of each device.

[0044] In this embodiment, a crucible transfer device 9 is also included, which is used to transfer the crucible from outside the calorimetric module 4 to inside the calorimetric module 4 and dock with the crucible handling device 42 to realize the taking and placing of the crucible. By providing the crucible transfer device 9, the crucible can be reliably and conveniently transferred from the crucible storage module 3 to the calorimetric module 4.

[0045] like Figure 4 As shown, the present invention also provides an unattended sample assay method, comprising:

[0046] S01, sample bottle processing: the sample bottle for storing the sample is transferred to the transceiver 11, and it is determined whether the calorimetric module 4 and / or the test module 5 are idle. If not, the sample bottle is transferred to the sample bottle storage device 12 for temporary storage. If yes, the sample bottle is transferred to the sample bottle shaking device 14 for even shaking, and then the mixed sample bottle is transferred to the sample bottle cover opening and closing device 13 to remove the bottle cover;

[0047] S02. Sampling and weighing: Take one or more samples from the sample bottle and put them into a crucible or sample boat, and weigh the crucible or sample in real time to determine the weight of the sample put into the crucible or sample boat;

[0048] S03, sample testing: determining whether the calorimetric module 4 and / or the testing module 5 are idle, if so, transferring the crucible to the calorimetric module 4 or the testing module 5 for sample testing; if not, transferring the crucible to the crucible storage module 3 for temporary storage;

[0049] S04, crucible cleaning: determine whether the sample test is completed. If so, take out the crucible and determine whether the crucible automatic cleaning module 6 is idle. If not, transfer the crucible to the crucible storage module 3 for temporary storage; if so, transfer the crucible to the crucible automatic cleaning module 6 for automatic cleaning. After the cleaning is completed, transfer the crucible to the crucible storage module 3.

[0050] The unattended sample testing method of the present invention realizes the cyclic testing of samples through the steps of sample bottle processing, sampling and weighing, sample testing, and crucible cleaning. When the samples are transmitted to the testing system, by judging whether the calorimetric module 4 and / or the testing module 5 are idle, the system can reasonably process the samples, and perform sampling operations or temporarily store the sample bottles containing the samples in a timely manner; after the sampling and weighing of the samples are completed, by further judging whether the calorimetric module 4 and / or the testing module 5 are idle, the system can reasonably and efficiently perform the testing of various indicators of the samples; by automatically judging whether the crucible automatic cleaning module 6 is idle, the cleaning work of the crucible can be completed efficiently and reasonably, and the testing system can work in a sustainable cycle without manual intervention.

[0051] In this embodiment, in step S02, the sample bottle after sampling is sent to the sample bottle storage device 12; when re-sampling is required, the sample bottle is sent from the sample bottle storage device 12 to the sampling device 21 to perform sampling again; when the sample bottle does not need to be sampled again, the sample bottle is sent to the sample bottle opening and closing cover device 13, the bottle cap is covered, and then the sample bottle is sent to the sending and receiving device 11 for sample bottle recovery.

[0052] In this embodiment, in step S03, when the calorimetric module 4 is judged to be idle, the crucible is transferred to the calorimetric module 4, the oxygen bomb is deflated and the oxygen bomb cover is opened, the oxygen bomb core is pulled out, the oxygen bomb body is cleaned, and a certain amount of water is added to the inner barrel of the calorific value testing device 41. The crucible is taken by the crucible processing device 42 and placed on the oxygen bomb core, and the oxygen bomb core is placed in the oxygen bomb body, and the cover is closed to perform oxygenation, and after oxygenation, it is sent to the calorific value testing device 41 for calorific value testing. By judging the operating state of the calorimetric module 4, the crucible is transferred only when the calorimetric module 4 is idle, and each module cooperates closely to ensure reliable and efficient operation of the system.

[0053] In this embodiment, in step S03, after the oxygen bomb has completed the oxygenation, it is determined whether the calorific value testing device 41 is normal and idle. If so, the oxygen bomb after the oxygenation is sent to the calorific value testing device 41 for calorific value testing. If not, the oxygen bomb is sent to the oxygen bomb storage device 46 for temporary storage or parked at the oxygenation station. By further determining whether the calorific value testing device 41 has a fault, it is possible to avoid sending the oxygen bomb to the faulty calorific value testing device 41, thereby improving the reliability of the system.

[0054] In this embodiment, in step S03, after the calorific value test is completed, it is determined whether the ignition is successful. If not, the oxygen bomb is sent to the oxygen bomb storage device 46 and an alarm is sounded to remind manual processing. If the ignition is successful, the oxygen bomb is deflated, the oxygen bomb cover is opened, the oxygen bomb core is taken out after correction, the crucible is taken out, the oxygen bomb body is cleaned, the next crucible is placed on the oxygen bomb core, the oxygen bomb core is placed in the oxygen bomb body, and the cover is closed for oxygen filling. It is determined whether the calorific value test device 41 is idle. If so, it is sent to the calorific value test device 41 after oxygen filling for calorific value testing; if not, the oxygen bomb is sent to the oxygen bomb storage device 46 for temporary storage. When the calorific value test is performed on the sample, the sample in the oxygen bomb may fail to ignite. By distinguishing the ignition situation, the sample with ignition failure can be found in time to avoid affecting the accuracy of the experimental results.

[0055] In this embodiment, in step S03, the test module 5 includes a sulfur test module 51, a carbon, hydrogen and nitrogen test module 52, and a water-ash test module 53. Multiple test modules 5 can perform sample tests simultaneously without interfering with each other, which greatly improves the working efficiency of the test system. In other embodiments, the test modules 5 can be deleted as needed.

[0056] In this embodiment, in step S03, when the sulfur testing module 51 is judged to be idle, the crucible or sample boat is sent to the additive adding module 8, and the corresponding additive is added to the crucible or sample boat, and then it is sent to the sulfur analysis equipment for sulfur content testing. When the sample is tested for sulfur content, a certain amount of catalyst is usually required. By judging the operating state of the sulfur testing module 51, the system can add the corresponding additive at the appropriate time.

[0057] In this embodiment, in step S03, when the carbon, hydrogen and nitrogen testing module 52 is judged to be idle, the crucible is sent into the carbon, hydrogen and nitrogen testing module 52, the sample carrier is placed, the sample is packaged, and after the sample packaging is completed, it is sent to the carbon, hydrogen and nitrogen tester for testing. After the experiment is completed, the sample carrier is sent to the crucible storage module 3. By judging the operating state of the carbon, hydrogen and nitrogen testing module 52, it is ensured that the crucible is sent in when it is idle, and automatic sample packaging is achieved.

[0058] In this embodiment, in step S04, when the crucible is cleaned, it is determined whether the crucible is a volatile crucible. If so, the volatile crucible and the crucible cover are sent to the water-ash test module 53 for burning. After the burning is completed, it is determined whether the automatic crucible cleaning module 6 is idle. If not, the crucible is sent to the crucible storage module 3 for temporary storage. If so, the crucible is sent to the automatic crucible cleaning module 6 for automatic cleaning. After the cleaning is completed, the crucible is transferred to the crucible storage module 3. By distinguishing the volatile crucible, it can be burned and automatically cleaned in time, ensuring that the crucible is thoroughly cleaned, so as to avoid affecting the test result of the next sample during recycling.
