Description

Technical Field

[0001] This utility model relates to the field of total moisture testing technology, and in particular to a total moisture testing system. Background Technology

[0002] A total moisture testing system is an automated device used to determine the total moisture content in solid fuels (such as coal and coke). Its core objective is to improve testing efficiency and the accuracy of results by reducing human intervention and standardizing operating procedures.

[0003] Chinese patent document CN119044516A discloses a coal sample total moisture testing device and testing method, including a workbench; a robot body is slidably connected to the top of the outer wall of the workbench via a slide table; a pair of drying boxes and cooling boxes are fixedly connected to the two sides of the top of the outer wall of the workbench, and the pair of drying boxes and cooling boxes are symmetrical about the center line of the workbench.

[0004] Chinese patent document CN112782033A discloses an automatic online moisture testing system, including an external chamber, a sample disposal device, a sample reduction device, a sample processing device, an oven device, a mobile robot, a nitrogen generator, and a control device. The sample processing device is used to weigh an empty shallow pan, collect the reduced sample into the shallow pan, flatten the sample in the shallow pan, and weigh the total weight of the shallow pan and the sample. The nitrogen generator is used to provide nitrogen to the space inside the oven device.

[0005] As can be seen from the above, the existing total moisture testing systems represented by CN119044516A and CN112782033A usually lack sample backup and sample secondary testing functions. When abnormal test results occur, it is difficult to trace the source, and sample moisture data is easily missing, resulting in low accuracy. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a full moisture testing system with high automation, high testing efficiency, convenient sample inspection and high testing accuracy.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A total moisture testing system includes a transfer module, a sample reduction module, an oven weighing module, a waste sample recovery module, a sample bottle receiving and storage module, and a control component.

[0009] The reduction module is used to reduce the sample in the sample bottle into test sample and preparation sample;

[0010] The oven weighing module is used to temporarily store sample trays and to dry and weigh sample trays containing test samples. Test samples that have undergone constant weight treatment are discarded.

[0011] The waste sample recovery module is used to recover waste samples and clean the sample tray;

[0012] The sample bottle receiving and storage module is used to receive, send, and store sample bottles;

[0013] The transfer module is used to transfer sample bottles and / or sample trays between various workstations;

[0014] The control component is used to control the operation of each module.

[0015] As a further improvement to the above technical solution:

[0016] The sample reduction module includes a material conveying line and a feeding mechanism, a sample reduction mechanism, and a sample receiving mechanism arranged sequentially along the material conveying line. The feeding mechanism is used to feed the sample from the sample bottle onto the material conveying line. After feeding, the sample bottle is transferred by the transfer module to the sample receiving mechanism, which is located at the end of the material conveying line. The sample reduction mechanism is used to reduce the sample on the material conveying line. The reduced sample falls into the sample tray, and the remaining sample is continued to be conveyed by the material conveying line and falls into the sample bottle on the sample receiving mechanism.

[0017] The reduction mechanism includes a circulating conveyor line located above the material conveyor line. The conveying direction of the material conveyor line is perpendicular to the conveying direction of the circulating conveyor line. The circulating conveyor line is equipped with a scraper, which is used to circulate and convey the scraper to intermittently scrape the sample flow off the material conveyor line.

[0018] The material conveying line is provided with a partition plate below the circulating conveying line. The partition plate is aligned with the center line of the scraper. The partition plate is provided with a discharge pipe on both sides, and the sample tray is provided at the bottom of the discharge pipe.

[0019] The oven weighing module includes an oven module frame, on which an oven mechanism, a sample tray storage mechanism, and a weighing mechanism are provided. The oven mechanism includes multiple independently set ovens. The sample tray storage mechanism is used for temporary storage and cooling of the sample trays, and the weighing mechanism is used for weighing the sample trays.

[0020] The weighing mechanism includes a balance and a leveling assembly. The leveling assembly includes a mounting base, an elastic element, and a scraper mounted on the mounting base. The elastic element is mounted on the mounting base and is used to buffer the load generated by the scraper contacting the sample in the sample tray.

[0021] The waste sample recycling module includes a material level detection mechanism, and a cleaning mechanism, a waste sample discharge pipe and a collection box connected in sequence from top to bottom. The waste sample discharge pipe and the collection box are detachably connected, and the material level detection mechanism is used to detect the material level height in the collection box.

[0022] The sample bottle receiving and storage module includes a sample bottle storage rack and a pneumatic transport mechanism. The sample bottle storage rack is provided with multiple storage sections for placing sample bottles, and the pneumatic transport mechanism is used to receive and send sample bottles. Each of the storage sections is set up independently.

[0023] The transfer module includes a transfer robot, which is equipped with a clamping frame. The clamping frame is equipped with a first clamping component and a second clamping component. The first clamping component includes at least a pair of opposing grippers for gripping the body of the sample bottle. The second clamping component includes a tray for supporting the edge of the sample tray.

[0024] It also includes a manual sampling module, which includes a manual sampling rack with a turntable and a baffle. The turntable has multiple placement parts for placing sample bottles along its circumference. The baffle is located above the turntable and has at least one first notch and at least one second notch. The first notch and the turntable form a manual sampling position, and the second notch and the turntable form a robot bottle picking position.

[0025] Compared with the prior art, the advantages of this utility model are:

[0026] 1. The total moisture testing system of this utility model is highly automated in its overall system design, with minimal manual intervention, high testing efficiency, and intelligent management. By dividing the sample after reduction into test samples and reserve samples, and storing the reserve samples for future reference, the reserve samples can be retested when abnormal test results occur, facilitating traceability and ensuring high testing accuracy.

[0027] 2. The total moisture testing system of this utility model can recycle the remaining samples (i.e., spare samples) after reduction (excluding the test samples) for future reference through the residual sample receiving mechanism, which can ensure that the samples are not wasted, facilitate traceability, and have high test accuracy. The sample bottles that have completed feeding are transferred from the feeding mechanism to the residual sample receiving mechanism through the transfer module for residual sample recycling, which can reuse the sample bottles. The system has a compact structure and low cost.

[0028] 3. The total moisture testing system of this utility model divides the sample scraped off by the scraper into two parts by a partition plate. The scraped samples fall into two sample trays through two discharge pipes, which are parallel test samples. The two test samples can be used to verify the results of each other, resulting in higher test accuracy.

[0029] 4. The total moisture testing system of this utility model integrates the oven mechanism, sample tray storage mechanism, and weighing mechanism into the same module, reducing the sample tray transfer distance. Especially when the sample needs to be dried for inspection, and frequent transfer between the oven mechanism, sample tray storage mechanism, and weighing mechanism is required, the transfer efficiency is higher, and the risk of sample falling out of the sample tray is reduced, resulting in smaller test result errors. Each oven can independently adjust its temperature and oven atmosphere. Independent temperature adjustment avoids the problems of excessive volume and low temperature control accuracy of traditional single large ovens. Independent oven atmosphere adjustment allows the air gas to be introduced only into the oven that needs to work, resulting in high energy utilization efficiency. Different air gases can be introduced into different ovens, making it highly adaptable.

[0030] 5. The total moisture testing system of this utility model, by setting up an elastic element, allows the scraper to make flexible contact with the sample. When the transfer module drives the sample tray to rise and contact the scraper, the elastic element can buffer the instantaneous load generated between the scraper and the transfer module to prevent the instantaneous load from being too large. When the scraper moves to flatten the sample, the elastic element can buffer the working load generated between the scraper and the transfer module, reduce load fluctuation, and have good stability. Furthermore, under the action of the elastic force of the transfer module, the scraper can always be pressed firmly on the sample, resulting in more uniform flattening and a better flattening effect.

[0031] 6. The total moisture testing system of this utility model detects the material level in the collection box through the material level detection mechanism. This can prevent excessive waste samples in the collection box from clogging the waste sample discharge pipe and reduce the cleaning frequency of the collection box. It has a simple and reliable structure and high working efficiency.

[0032] 7. The total moisture testing system of this utility model uses a pneumatic transport mechanism to receive and send sample bottles, which has high transport efficiency and the sample bottles are always transported in a closed pipeline, ensuring good safety. In addition, the storage section can store sample bottles containing reduced-size backup samples or other pre-packaged sample bottles, and it is also convenient to send the stored sample bottles to external equipment, making it highly adaptable.

[0033] 8. The total moisture testing system of this utility model integrates the gripper and the tray into the same fixture. By adjusting the angle of the fixture, the form of the fixture for holding sample bottles and the form of holding sample trays can be changed. There is no need to equip multiple mechanical grippers or replace the mechanical grippers. The system can hold sample bottles and sample trays, which is simple to operate, has high work efficiency, and high space utilization.

[0034] 9. In the total moisture testing system of this utility model, when the pneumatic pipeline in the pneumatic transport mechanism malfunctions and needs to be stopped, the sample bottle can be manually placed from the manual placement position onto the turntable, and then the transfer module can take it out from the robot bottle-taking position for subsequent processes. There is no need to wait for the pneumatic pipeline to be restored before the subsequent processes can be carried out. The testing efficiency is high and the adaptability is strong. By setting the first and second notches on the baffle, the sample bottle can only be put in or taken out from the manual placement position and the robot bottle-taking position. The structure is simple and reliable. Attached Figure Description

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0050] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0051] like Figures 1 to 11 As shown, the total moisture testing system of this embodiment includes a transfer module 1, a sample reduction module 2, an oven weighing module 3, a waste sample recovery module 4, a sample bottle receiving and storage module 5, and a control component.

[0052] The reduction module 2 is used to reduce the sample in sample bottle 91 into test sample and reserve sample;

[0053] The oven weighing module 3 is used to temporarily store the sample tray 92 and to dry and weigh the sample tray 92 containing the test sample. The test sample after constant weight treatment becomes a discard sample.

[0054] The waste sample recovery module 4 is used to recover waste samples and clean the sample tray 92;

[0055] The sample bottle receiving, sending, and storage module 5 is used to receive, send, and store sample bottles 91;

[0056] The transfer module 1 is used to transfer sample bottles 91 and / or sample trays 92 between workstations (i.e., between different modules, or between different workstations of a single module);

[0057] The control component is used to control the operation of each module.

[0058] In this embodiment of the total moisture testing system, during operation, the sample bottle receiving and storage module 5 receives sample bottles 91 containing the original sample or sample bottles 91 containing reserve samples transferred from the reduction module 2. The transfer module 1 transfers the sample bottles 91 from the sample bottle receiving and storage module 5 to the reduction module 2 for reduction. The reduced sample is divided into test samples and reserve samples. The reserve samples are placed into sample bottles 91 and transferred by the transfer module 1 to the sample bottle receiving and storage module 5 for storage and future reference. The test samples are placed into sample trays 92 and transferred by the transfer module 1 to the sample bottle receiving and storage module 5 for storage and future reference. The sample is transferred from the transfer module 1 to the oven weighing module 3 for drying and weighing. After constant weight treatment (i.e., after the total moisture test is completed), the test sample becomes a discard sample. The transfer module 1 transfers the sample tray 92 containing the discard sample to the discard sample recovery module 4 to recover the discard sample and clean the sample tray 92. The cleaned empty sample tray 92 is then transferred from the transfer module 1 to the oven weighing module 3 for temporary storage, and then transferred from the transfer module 1 to the reduction module 2 to receive the test sample. The above process can be repeated to continuously perform the total moisture test. The total moisture test system of this embodiment has a highly automated overall system design with minimal manual intervention, high testing efficiency, and intelligent management. By dividing the reduced sample into test samples and reserve samples, and storing the reserve samples for future reference, when the test results are abnormal, the reserve samples can be retested, which facilitates traceability, makes sample review convenient, and ensures high test accuracy.

[0059] Preferably, in this embodiment, each module is arranged along the circumference of the transfer module 1 to facilitate the transfer of the transfer module 1.

[0060] Furthermore, such as Figure 4 and Figure 5 As shown, in this embodiment, the sample reduction module 2 includes a material conveying line 21, and a feeding mechanism 22, a sample reduction mechanism 23, and a sample receiving mechanism 24 arranged sequentially along the material conveying line 21. The feeding mechanism 22 is used to feed the sample in the sample bottle 91 onto the material conveying line 21. The sample bottle 91 after feeding is transferred by the transfer module 1 to the sample receiving mechanism 24. The sample receiving mechanism 24 is located at the end of the material conveying line 21. The sample reduction mechanism 23 is used to reduce the sample on the material conveying line 21. The reduced test sample falls into the sample tray 92, and the remaining sample is continued to be conveyed by the material conveying line 21 and falls into the sample bottle 91 on the sample receiving mechanism 24. The remaining sample (i.e., spare sample) after reduction is collected and kept for future reference by the sample receiving mechanism 24. This ensures that the sample is not wasted, facilitates traceability, and ensures high accuracy of test results. The sample bottle 91 that has been fed is transferred from the feeding mechanism 22 to the remaining sample receiving mechanism 24 by the transfer module 1 for sample recycling. The sample bottle 91 can be reused, and the structure is compact and low cost.

[0061] Preferably, in this embodiment, the remaining sample receiving mechanism 24 includes a discharge hopper located below the end of the material conveying line 21. A bracket is provided below the discharge hopper, and a lifting drive is connected to the bottom of the bracket. A weighing sensor is provided on the bracket. After the sample bottle 91 on the bracket has received the remaining sample, the lifting drive drives the bracket to lower the sample bottle 91, which is then transferred by the transfer module 1. Since the weighing sensor is provided on the bracket, the sample bottle 91 can be transferred in time before it is full.

[0062] Furthermore, in this embodiment, the reduction mechanism 23 includes a circulating conveyor line 231 located above the material conveyor line 21. The conveying direction of the material conveyor line 21 is perpendicular to the conveying direction of the circulating conveyor line 231. A scraper 232 is provided on the circulating conveyor line 231, which is used to circulate and convey the scraper 232 to intermittently scrape off the sample flow on the material conveyor line 21. Since the conveying direction of the material conveyor line 21 is perpendicular to the conveying direction of the circulating conveyor line 231, when the scraper 232 circulates and conveys the sample flow through the reduction mechanism 23, the scraper 232 scrapes off the sample flow on the material conveyor line 21. By controlling the running speed of the material conveyor line 21 and the circulating conveyor line 231, the reduction ratio can be adjusted.

[0063] Furthermore, in this embodiment, a partition plate 26 is provided below the circulating conveyor line 231 in the material conveyor line 21. The partition plate 26 is aligned with the center line of the scraper 232. Drop pipes 25 are provided on both sides of the partition plate 26, and sample trays 92 are provided at the bottom of the drop pipes 25. The partition plate 26 divides the sample scraped by the scraper 232 into two parts. The scraped samples fall into two sample trays 92 through the two drop pipes 25, serving as parallel test samples. The two test samples can be used to verify the results, resulting in higher test accuracy.

[0064] Preferably, in this embodiment, a rectification mechanism 27 is further provided between the feeding mechanism 22 and the reduction mechanism 23. The rectification mechanism 27 includes a height limiting plate 271, which forms a rectification channel with the material conveying line 21. A rectification agitator is also provided upstream of the height limiting plate 271. The height of the sample flow is controlled by the height limiting plate 271. When the sample passes through the rectification mechanism 27, a sample flow with a fixed height and width is formed, which facilitates accurate subsequent reduction ratio. The rectification agitator stirs the sample in front of the rectification channel to prevent the sample from clogging at the rectification channel.

[0065] Preferably, in this embodiment, the reduction module 2 further includes a cap opening and closing mechanism, which can open the cap of the sample bottle 91 to be fed in the feeding mechanism 22 and close the cap of the sample bottle 91 received by the receiving sample mechanism 24. The structure is simple and reliable.

[0066] Furthermore, such as Figure 6 and Figure 7As shown, in this embodiment, the oven weighing module 3 includes an oven module frame 31. The oven module frame 31 is provided with an oven mechanism 32, a sample tray temporary storage mechanism 33 and a weighing mechanism 34. The oven mechanism 32 includes multiple independently set ovens 321. The sample tray temporary storage mechanism 33 is used to temporarily store and cool the sample tray 92. The weighing mechanism 34 is used to weigh the sample tray 92. By integrating the oven mechanism 32, sample tray storage mechanism 33, and weighing mechanism 34 into the same module, the transfer distance of the sample tray 92 is reduced. Especially when the sample needs to be dried for inspection, the transfer efficiency is higher when the sample is frequently transferred between the oven mechanism 32, sample tray storage mechanism 33, and weighing mechanism 34. This also reduces the risk of the sample falling out of the sample tray 92 and results in smaller test error. Each oven 321 can independently adjust its temperature and oven atmosphere. Independent temperature adjustment avoids the problems of excessive volume and low temperature control accuracy of traditional single large ovens. Independent oven atmosphere adjustment allows the air gas to be introduced only into the oven 321 that needs to work, resulting in high energy efficiency. Different air gases can be introduced into different ovens 321, making it highly adaptable.

[0067] Furthermore, in this embodiment, the weighing mechanism 34 includes a balance 341 and a leveling component 342. The leveling component 342 includes a mounting base 3421, an elastic element 3422, and a scraper 3423 disposed on the mounting base 3421. The elastic element 3422 is disposed on the mounting base 3421 and is used to buffer the load generated by the scraper 3423 contacting the sample in the sample tray 92. During operation, the sample tray 92 containing the sample is lifted by the transfer module 1 to the leveling component 342, which in turn raises the sample tray 92 and inserts the scraper 3423 into the sample, leveling the sample. By setting an elastic element 3422 (such as a spring), the scraper 3423 is in flexible contact with the sample. When the transfer module 1 raises the sample tray 92 and contacts the scraper 3423, the elastic element 3422 can buffer the instantaneous load generated between the scraper 3423 and the transfer module 1, preventing the instantaneous load from being too large. When the scraper 3423 moves to level the sample, the elastic element 3422 can buffer the working load generated between the scraper 3423 and the transfer module 1, reducing load fluctuations and providing good stability. Furthermore, under the action of the elastic force of the transfer module 1, the scraper 3423 can always be pressed firmly on the sample, resulting in more uniform leveling and a better leveling effect.

[0068] Furthermore, such as Figure 8As shown, in this embodiment, the waste sample recycling module 4 includes a material level detection mechanism 41, and a cleaning mechanism 42, a waste sample discharge pipe 43, and a collection box 44 connected sequentially from top to bottom. The waste sample discharge pipe 43 is detachably connected to the collection box 44. The material level detection mechanism 41 is used to detect the material level in the collection box 44. By detecting the material level in the collection box 44 through the material level detection mechanism 41, it is possible to prevent excessive waste sample in the collection box 44 from clogging the waste sample discharge pipe 43, and to reduce the cleaning frequency of the collection box 44. The structure is simple, reliable, and has high working efficiency.

[0069] Furthermore, such as Figure 9 As shown, in this embodiment, the sample bottle receiving and storage module 5 includes a sample bottle storage rack 51 and a pneumatic transport mechanism 52. The sample bottle storage rack 51 is provided with multiple storage sections 511 for placing sample bottles 91. The pneumatic transport mechanism 52 is used to receive and send sample bottles 91, and each storage section 511 is independently set. The pneumatic transport mechanism 52 is used to receive and send sample bottles 91, which has high transportation efficiency and ensures good safety as the sample bottles 91 are always transported in a closed pipeline. Furthermore, the storage sections 511 can store sample bottles 91 containing reduced-size backup samples or other pre-packaged sample bottles 91, and also facilitates the sending of stored sample bottles 91 to external devices, making it highly adaptable.

[0070] Furthermore, such as Figure 2 and Figure 3 As shown, in this embodiment, the transfer module 1 includes a transfer robot, which is equipped with a clamping frame 11. The clamping frame 11 is equipped with a first clamping component 12 and a second clamping component 13. The first clamping component 12 includes at least a pair of opposing grippers 121, which are used to clamp the body of the sample bottle 91. The second clamping component 13 includes a tray support 131, which is used to support the edge of the sample tray 92. By integrating the grippers 121 and the tray support 131 onto the same clamp, and adjusting the angle of the clamp, the clamp can be switched between clamping the sample bottle 91 and clamping the sample tray 92. This eliminates the need for multiple mechanical grippers or replacement of the mechanical grippers, thus achieving the clamping of the sample bottle 91 and the sample tray 92. The operation is simple, the work efficiency is high, and the space utilization rate is high.

[0071] Furthermore, such as Figure 10 and Figure 11As shown, this embodiment also includes a manual sampling module 6, which includes a manual sampling rack 61. The manual sampling rack 61 is provided with a turntable 62 and a baffle 63. The turntable 62 is provided with a plurality of placement parts 621 for placing sample bottles 91 along the circumference. The baffle 63 is located above the turntable 62. The baffle 63 is provided with at least one first notch 631 and at least one second notch 632. The first notch 631 and the turntable 62 form a manual sampling position 641, and the second notch 632 and the turntable 62 form a robot bottle picking position 642. When the pneumatic pipeline in the pneumatic transport mechanism 52 malfunctions and needs to be stopped, the sample bottle 91 can be manually placed from the manual placement position 641 onto the turntable 62, and then the transfer module 1 can take it out from the robot bottle retrieval position 642 for subsequent processes. There is no need to wait for the pneumatic pipeline to be restored before the subsequent processes can be carried out, which has high testing efficiency and strong adaptability. By setting the first notch 631 and the second notch 632 on the baffle 63, the sample bottle 91 can only be put in or taken out from the manual placement position 641 and the robot bottle retrieval position 642, which is simple and reliable.

[0072] Preferably, in this embodiment, the manual sampling module 6 further includes a limiting mechanism 65 for restricting the removal of sample bottles 91 from the manual sampling position 641. By setting the limiting mechanism 65, it is possible to prevent the sample bottles 91 from being illegally removed from the manual sampling position 641, or even from being replaced or stolen. The samples on the turntable 62 can only be removed from the robot bottle-retrieving position 642 by the transfer module 1, ensuring the integrity, safety, and authenticity of the samples.

[0073] Preferably, in this embodiment, the limiting mechanism 65 includes a limiting drive 651 and a limiting member 652 located above the first notch 631. The output end of the limiting drive 651 is connected to the limiting member 652 and is used to drive the limiting member 652 to rise and fall. The placement part 621 is a placement groove, and the limiting member 652 is a limiting plate. When the limiting member 652 descends to the point where the distance between the limiting member 652 and the upper surface of the sample bottle 91 is less than the depth of the placement part 621, the sample bottle 91 cannot be taken out from the placement part 621. The structure is simple and reliable.

[0074] Of course, in other embodiments, the limiting mechanism 65 can also be implemented in other ways. For example, a locking mechanism can be provided at the bottom of the placement part 621. When the sample bottle 91 is placed in the manual placement position 641, the locking mechanism locks the sample bottle 91 so that the sample bottle 91 cannot be taken out from the placement part 621 corresponding to the manual placement position 641. Only when the sample bottle 91 is transported to the robot bottle taking position 642 will the locking mechanism release the sample bottle 91, and the transfer module 1 can take out the sample bottle 91.

[0075] Preferably, in this embodiment, the manual sampling module 6 further includes a bottle disposal mechanism 66 for disposing of bottles. When the pneumatic transport mechanism 52 is unable to transport the sample bottle 91 to the outside, the bottle can be manually disposed of through the bottle disposal mechanism 66 and the sample bottle 91 can be transferred to the outside.
