Description

Technical Field

[0001] This invention belongs to the field of coal sample property testing technology, and particularly relates to a sample injection device, a bonding index tester, and a method for measuring the bonding index. Background Technology

[0002] The bituminous coal caking index can determine the caking and coking properties of coal. It can reflect the coal's caking ability during combustion and determine its final use based on the index level, such as coking, blast furnace injection, or gasification. Therefore, the bituminous coal caking index is a particularly important indicator.

[0003] The method for determining the caking index of bituminous coal is based on the national standard GB / T 5447-2014 "Method for Determination of Caking Index of Bituminous Coal". Special anthracite and the test coal sample are mixed in a ratio of 5:1 or 3:3, stirred evenly, leveled, and then pressed tightly in a crucible with a pressure block. The crucible is covered, heated for coking, and then cooled to room temperature. The crucible cover and pressure block are removed, and the total mass of the coke residue is weighed. The residue is then placed in a rotating drum for the first rotating drum test. After the first rotating drum test, the coke residue is sieved using a 1mm round-hole sieve, and the mass of the residue on the sieve is weighed. The residue is then placed in the rotating drum for the second rotating drum test, sieved, and weighed. Finally, the caking index is calculated.

[0004] Traditional caking index determination is done manually, which is labor-intensive, in harsh environments, prone to human error, inefficient, and results in inconsistent and inaccurate results. There is also the possibility of human error. Chinese patent application CN117347647A discloses a fully automated caking index tester. In use, after the weighed sample is placed on the platform, the subsequent measurement process is fully automated. The entire experiment can be completed unattended, improving the accuracy and consistency of the results and eliminating the possibility of human error. It completely eliminates the tedious work involved in caking index determination, achieving full automation. However, before the experiment, this patent still requires manual weighing and mixing of special anthracite and the test coal sample in a 5:1 or 3:3 ratio, and then placing the crucible containing the sample on the platform. This still requires manual operation and cannot truly achieve fully unattended operation for the entire caking index determination process. Summary of the Invention

[0022] As a general technical concept, the present invention also provides a method for measuring the above-mentioned fully automated adhesion index tester, comprising the following steps: S1: The crucible rotation and lifting mechanism rotates, causing the crucible above it to move between the first feeding and weighing mechanism and the anthracite feeding mechanism.

After the anthracite feeding mechanism quantitatively dispenses anthracite into the crucible, the crucible rotation and lifting mechanism rises.

The crucible rotation and lifting mechanism descends, causing the crucible to fall above the second feeding and weighing mechanism. After the test coal feeding mechanism quantitatively drops test coal into the crucible, the crucible rotation and lifting mechanism rises.

[0023] Compared with the prior art, the advantages of the present invention are as follows: The automatic weighing and mixing device of the present invention involves a crucible rotation and lifting mechanism that continues to rotate, moving the crucible above it between the first feeding and weighing mechanism and the anthracite feeding mechanism. The crucible then falls above the first feeding and weighing mechanism, allowing the anthracite feeding mechanism to quantitatively add anthracite into the crucible, thus automating the sampling of the anthracite. Next, the crucible rotation and lifting mechanism continues to rotate, moving the crucible above it between the second feeding and weighing mechanism and the test coal feeding mechanism. The crucible then falls above the second feeding and weighing mechanism, allowing the test coal feeding mechanism to quantitatively add test coal into the crucible, thus automating the sampling of the test coal. Through these operations, anthracite and test coal are quantitatively weighed in the same crucible, achieving fully automated, unmanned operation of the test samples. The aforementioned automatic weighing and mixing device is applied to a fully automated caking index tester, achieving unmanned operation throughout the entire process. Pre-experiment preparation and the entire subsequent process require no human intervention, completely solving the problem of manual involvement and laying the foundation for the automated networking of various indicators in the coal industry. Furthermore, the entire experimental process is completely unaffected by human factors (zero human intervention), ensuring the authenticity of the experimental results and thoroughly solving the problem of high labor costs, thus meeting the needs of modern technological development.

[0062] In this embodiment, specifically, the elastic connection device includes a connecting guide rod 14213, a first elastic spring 1425, and a second elastic spring 1426. One end of the connecting guide rod 14213 is fixed to the locking seat 1423, and the other end of the connecting guide rod 14213 passes through the feeding mechanism plate 1427, with a retaining plate at the other end. The first elastic spring 1425 is sleeved on the connecting guide rod 14213 and is located between the locking seat 1423 and the feeding mechanism plate 1427. The second elastic spring 1426 is sleeved on the connecting guide rod 14213 and is located between the feeding mechanism plate 1427 and the retaining plate. The first elastic spring 1425 and the second elastic spring 1426 can act as a buffer. When the capping and gripping mechanism 141 rotates and screws the cap on the coal bottle 1601, it can provide a buffer in the vertical direction (the cap of the coal bottle 1601 is threaded to the bottle body 16013), preventing the coal bottle 1601 from getting stuck or damaged. When the coal bottle 1601 is in an inverted feeding position, the vibration generated by the test coal vibration motor 14212 will transmit the vibration and cause the sample coal in the coal bottle 1601 to flow out.

[0063] In this embodiment, to prevent coal from spilling during rotation when the coal bottle 1601 is unscrewed, the test coal clamping and feeding mechanism 142 is also equipped with a test coal dust cover 1421. The test coal dust cover 1421 is inverted cone shape, and a test coal guiding and discharging mechanism is provided at the bottom opening of the test coal dust cover 1421. The test coal guiding and discharging mechanism includes a test coal circular trough located at the bottom opening of the test coal dust cover 1421. A test coal falling guide pipe 142102 is provided at the center of the test coal circular trough. The center of the test coal falling guide pipe 142102 coincides with the center of the outlet of the coal bottle 1601 after it is inverted. The bottom opening of the side of the test coal circular trough is equipped with a test coal dust suction pipe 142101. When the small hole of the inner cap 16012 of the coal bottle 1601 is aligned with the inner hole of the test coal falling guide tube 142102, the test coal sample falls into the crucible 99 along the test coal falling guide tube 142102, and the sample coal outside the test coal falling guide tube 142102 falls into the test coal circular trough, which can be sucked away through the test coal dust suction pipe 142101.

[0064] In existing technologies, a baffle is typically placed directly against the coal outlet of the coal cylinder 1601. The baffle is opened when feeding material and closed when not feeding. The drawbacks of this method are that coal easily accumulates on the baffle, the opening and closing is not tight, and coal dust can spill to other areas. Furthermore, when feeding a different coal sample, there is a possibility of mixing with the previous sample, leading to inaccurate experimental results. Another existing method involves a sample coal with a feeding opening and closing device. After the experiment, the opening and closing device is manually removed for cleaning. This method results in larger and more numerous pieces of equipment and relies heavily on manual labor. The specific test coal clamping and feeding mechanism 142 used in this embodiment effectively solves the above problems, greatly reduces manual operation, and avoids coal mixing.

[0065] like Figures 9-11 As shown, in this embodiment, the coal discharge cylinder 1601 includes a cylinder body 16013, an inner cap 16012, and an outer cap 16011. Both the inner cap 16012 and the outer cap 16011 are fitted onto the opening of the cylinder body 16013. The outer cap 16011 is located outside the inner cap 16012, and the outer cap 16011 is threadedly connected to the opening of the cylinder body 16013. The inner cap 16012 has a discharge hole at its center, and the outer cap 16011 is fitted with a sealing element for sealing the discharge hole. Figures 9-11 Three different forms of inner cover 16012 and outer cover 16011 are shown, all of which can be used in this embodiment. Specifically, the discharge hole in the center of the inner cover 16012 is a small hole, and the sealing part on the outer cover 16011 can block the small hole after the cover is closed to prevent the coal sample in the coal bottle 1601 from spilling out. When it is necessary to discharge the test coal in the coal bottle 1601, the outer cover 16011 is unscrewed, and the test coal sample flows out from the small hole in the inner cover 16012 through the vibration of the test coal vibration motor 14212. The outflow speed of the test coal sample can be controlled by the vibration amplitude of the test coal vibration motor 14212.

[0066] In this embodiment, the upper inlet of the test coal falling guide pipe 142102 is frustoconical, with the top opening smaller than the lower outlet. A gap exists between the upper inlet of the test coal falling guide pipe 142102 and the outlet of the inverted coal dispensing bottle 1601. The upper inlet of the test coal falling guide pipe 142102 is formed with an inverted cone structure, effectively preventing other debris from falling into the crucible 99. Simultaneously, the presence of a certain gap between the test coal falling guide pipe 142102 and the coal dispensing bottle 1601 prevents material mixing.

[0067] The coal cylinder 1601 described above differs from existing methods. Existing methods involve a specially designed feed cap (called the feed cap) with a small feed hole. This hole interacts with the aforementioned stop block to either close or open; when open, feed is initiated. This requires tightening the cap on the coal cylinder 1601 itself before repeatedly turning the coal sample inside to even it out. Then, the cap-grabbing mechanism 141 removes the cap from the coal cylinder 1601 and replaces it with the feed cap for feeding. After feeding, the feed cap must be removed and placed in a cleanable area to remove any remaining coal (if not cleaned thoroughly, there is a possibility of mixed coal). The original cap is then replaced, making the process cumbersome. Using the coal cylinder 1601 with an inner cap 16012 and an outer cap 16011 as described in this embodiment simplifies the process. Simply remove the outer cap 16011 from the coal dispensing cylinder 1601 using the cap-grabbing mechanism 141. The coal dispensing cylinder 1601 then rotates downwards via the test coal clamping and feeding mechanism 142, activating the test coal vibration motor 14212 to discharge the coal. After discharge, it rotates upwards again, and the cap-grabbing mechanism 141 closes the outer cap 16011. No cleaning is required. This reduces operational steps, eliminates the risk of material mixing, and improves work efficiency.

[0068] like Figure 12 , Figure 13 As shown, in this embodiment, the crucible rotation and lifting mechanism 17 includes a crucible plate 1701, a crucible plate rotation mechanism 172 for driving the crucible plate 1701 to rotate, and a crucible plate lifting mechanism 171 for driving the crucible plate 1701 to lift. The crucible plate 1701 is provided with a plurality of receiving holes evenly distributed along its circumference. The side wall of the crucible 99 is provided with a protruding edge 991 for being locked in the receiving hole. The crucible 99 can be lifted and placed in the receiving hole.

[0069] In this embodiment, the crucible plate rotation mechanism 172 includes a crucible plate rotation mounting base 1724, a crucible plate rotation shaft 1722, a crucible plate crossed roller bearing 1723, and a crucible plate rotation drive 1725. The outer ring of the crucible plate crossed roller bearing 1723 is disposed on the crucible plate rotation mounting base 1724, and the crucible plate rotation shaft 1722 is fixedly disposed on the inner ring of the crucible plate crossed roller bearing 1723. One end of the crucible plate rotation shaft 1722 is connected to the crucible plate 1701, and the other end is connected to the crucible plate rotation drive 1725. The crucible plate rotation drive 1725 is disposed on the crucible plate rotation mounting base 1724. The crucible plate rotation mounting base 1724 is also provided with a crucible plate indexing device 1721 for realizing the indexing rotation of the crucible plate 1701. Driven by the crucible pan rotation drive 1725, the crucible pan rotation shaft 1722 can be rotated, thereby driving the crucible pan 1701 to rotate. Specifically, the crucible pan rotation drive 1725 can be a drive motor. Due to the presence of the crucible pan indexing device 1721, the crucible pan 1701 can be rotated in an indexing manner.

[0070] The crucible pan lifting mechanism 171 includes a crucible pan lifting support frame 1713, a crucible pan guiding device 1715, a crucible pan deep groove bearing 1711, an eccentric wheel 1712, and a crucible pan lifting drive component 1714. The crucible pan rotating mounting seat 1724 is connected to the crucible pan guiding device 1715. The crucible pan guiding device 1715 is slidably mounted on the crucible pan lifting support frame 1713. The crucible pan rotating mounting seat 1724 is supported on the crucible pan deep groove bearing 1711. The crucible pan deep groove bearing 1711 is sleeved on the eccentric wheel 1712. The eccentric wheel 1712 is connected to the crucible pan lifting drive component 1714. The crucible pan lifting drive component 1714 is mounted on the crucible pan lifting support frame 1713. The rotation of the crucible pan lifting drive 1714 drives the eccentric wheel 1712 to rotate, and due to the eccentricity, the crucible pan 1701 moves up and down. The crucible pan lifting drive 1714 can specifically be a drive motor.

[0071] like Figure 14 , Figure 15As shown, in this embodiment, the automatic weighing and mixing device further includes a bottle placement mechanism 16. The bottle placement mechanism 16 includes a bottle placement rotation mechanism 1603 and a bottle placement tray 1602 for placing the bottle 1601. The bottle placement rotation mechanism 1603 includes a positioning tray 16034, a bottle placement transmission device 16032, a bottle placement drive component 16031, a bottle placement rotation shaft 16036, and a positioning pin 16035 for positioning the bottle placement tray 1602. The positioning pin 16035 is located on the positioning tray 16034. On the 034, a positioning disk 16034 is mounted on the bottle-dispensing rotating shaft 16036, and a bottle-dispensing tray 1602 is mounted on top of the bottle-dispensing rotating shaft 16036. The bottle-dispensing tray 1602 is mounted on the positioning disk 16034 via a positioning pin 16035. The bottle-dispensing drive component 16031 is connected to the bottle-dispensing rotating shaft 16036 via a bottle-dispensing transmission device 16032. The bottle-dispensing rotating shaft 16036 is also equipped with a bottle-dispensing indexing device 16033 for realizing the indexing rotation of the bottle-dispensing tray 1602. Several coal bottles 1601 can be placed on the bottle-dispensing tray 1602. The bottle-dispensing tray 1602 is mounted on the positioning disk 16034 via the positioning pin 16035, which ensures accurate positioning of both. The bottle-dispensing tray 1602 can quickly place an entire tray of coal bottles 1601 directly onto the positioning disk 16034 of the bottle-dispensing rotating mechanism 1603. The bottle-dispensing rotation mechanism 1603 is mounted on the frame 1. Due to the presence of the bottle-dispensing indexing device 16033, the bottle-dispensing tray 1602 can be rotated in an indexing manner.

[0072] like Figure 16 , Figure 17 As shown, the specific working process of the anthracite weighing and feeding mechanism in this embodiment can be described as follows: Driven by the crucible plate rotation drive 1725 on the crucible rotation and lifting mechanism 17, the crucible plate 1701 carrying the empty crucible 99 rotates to a position where the empty crucible 99 is directly below the anthracite falling guide pipe 15072 of the anthracite feeding mechanism 15. Then, under the action of the crucible plate lifting drive 1714, the crucible plate 1701 is lowered to its lowest position, and the empty crucible 99 is lifted off the crucible plate 1701 by the first weighing rod 1801 on the first feeding and weighing mechanism 18 until it is completely detached from the crucible plate 1701. Then, the gate drive 1509 on the anthracite feeding mechanism 15 retracts, causing the gate 1508 to open the opening above the anthracite falling guide pipe 15072. The anthracite vibration motor 1511 is started, and the anthracite flows out through the small hole. The amplitude of the anthracite vibration motor 1511 is controlled to be large at first and then small, while the first feeding and weighing mechanism 18 takes a reading. As the weight approaches the specified value, the amplitude control decreases until the accuracy is reduced to one-thousandth. Upon reaching the specified weight, the anthracite vibration motor 1511 stops, and then the gate drive 1509 extends, causing the gate 1508 to block the opening above the anthracite falling guide pipe 15072, preventing coal from falling into the crucible 99 below and affecting the weighing accuracy. Then, the crucible tray lifting drive 1714 of the crucible rotation lifting mechanism 17 activates, raising the crucible tray 1701 to its highest position. The crucible 99, already containing anthracite, gradually detaches from the first weighing rod 1801 of the first feeding weighing mechanism 18 and is lifted onto the crucible tray 1701 by the protruding edge 991 on the side of the crucible 99, thus completing the anthracite feeding and weighing process. Afterwards, the crucible tray rotation drive 1725 of the crucible rotation lifting mechanism 17 operates, causing the crucible tray 1701 to rotate to the next test coal feeding station. Before starting the next crucible 99 feeding, start the vacuum cleaner to remove any remaining anthracite residue from the anthracite dust cover 1507 through the anthracite suction pipe 15071. This process enables fully automated anthracite feeding and weighing, replacing manual operation and laying the foundation for fully automated operation.

[0073] like Figures 18-20 As shown, the specific working process of the test coal weighing and feeding mechanism in this embodiment can be described as follows: The capping and gripping mechanism 141 of the test coal feeding mechanism 14, via the electric gripper fingers 1412 and the gripper 1411, grips the coal bottle 1601 from the bottle dispensing mechanism 16 and moves into the elastic clamping spring 1424 of the test coal clamping and feeding mechanism 142. Simultaneously, driven by the crucible plate rotation drive 1725, the crucible plate 1701 of the crucible 99 containing anthracite coal rotates to a position directly below the test coal falling guide pipe 142102 of the test coal clamping and feeding mechanism 142. The clamping spring drive 1422 retracts, pulling the elastic clamping spring 1424 to clamp the coal bottle 1601. Through the action of the flipping drive 14210, the feeding mechanism plate 1427 swings 90 degrees, ensuring the test coal in the coal bottle 1601 is mixed evenly. Then, with the coal cylinder 1601 upright, the electric clamping finger 1412 drives the clamping jaw 1411 to clamp the outer cap 16011 of the coal cylinder 1601, and the capping begins. Due to the buffering effect of the second elastic spring 1426, there will be no jamming or other phenomena during the capping process. After the cap is tightened, the test coal lifting mechanism 1413 of the test coal feeding mechanism 14, under the action of the lifting motor 14131, rises to the highest position along with the outer cap 16011 (without affecting the rotation of the coal cylinder 1601). Then, under the action of the flipping drive 14210, the feeding mechanism plate 1427 rotates the clamped coal cylinder 1601 (without the outer cap 16011) to an inverted state. Simultaneously, under the action of the crucible pan lifting drive 1714, the crucible rotation and lifting mechanism 17 lowers the crucible pan 1701 to its lowest position. The crucible 99 containing anthracite is lifted off the crucible pan 1701 by the second weighing rod 1901 on the second feeding and weighing mechanism 19 until it is completely detached from the crucible pan 1701. The test coal vibration motor 14212 is started, and the test coal flows out through the small hole on the inner cover 16012 of the coal dispensing bottle 1601. The amplitude of the test coal vibration motor 14212 is controlled to be large at first and then small, while the second feeding and weighing mechanism 19 takes a reading. The closer to the specified weight value, the smaller the amplitude control becomes, until the accuracy is reduced to one-thousandth. After reaching the specified weight, the test coal vibration motor 14212 is stopped, and then, under the action of the flipping drive 14210, the coal dispensing bottle 1601 is reversed and returned to the upright position. The electric gripper 1412, with the gripper 1411 holding the outer cap 16011, begins the cap-closing action. After the cap is closed, the clamping spring drive 1422 causes the elastic clamping spring 1424 to release the coal bottle 1601. Then, the cap-screwing and gripping mechanism 141 returns the coal bottle 1601 to the bottle-dispensing position of the bottle-dispensing mechanism 16. By repeating the above actions, different coal bottles 1601 can be fed and weighed.Simultaneously, the crucible tray lifting drive 1714 of the crucible rotation and lifting mechanism 17 activates, raising the crucible tray 1701 to its highest position. The crucible 99, already containing anthracite and test coal, gradually detaches from the second weighing rod 1901 of the second feeding and weighing mechanism 19 and is lifted onto the crucible tray 1701 by the protruding edge 991 on the side of the crucible 99, thus completing the feeding and weighing of the test coal. Afterwards, the crucible tray rotation drive 1725 of the crucible rotation and lifting mechanism 17 operates, causing the crucible tray 1701 to rotate to the next station. If a large amount of coal dust accumulates in the test coal dust cover 1421, a vacuum cleaner can be activated to remove the coal residue inside the dust cover 1421 through the test coal suction pipe 142101. Through the above operations, anthracite and test coal can be weighed and mixed in a specific ratio, which can then be grasped by the robotic arm 7 for subsequent processes, achieving unmanned operation.

[0074] like Figures 22-24 As shown, the fully automatic caking index tester of this embodiment includes a frame 1, on which a stirring mechanism 3, a coking pre- and post-coking treatment mechanism 4, a pressure device 10, a heating mechanism 5, a cooling chamber 12, a drum mechanism 6, a sieving mechanism 9, a robotic arm 7, and a weighing balance 8 are provided. It also includes the aforementioned automatic weighing and mixing device. The anthracite weighing and feeding mechanism, the test coal weighing and feeding mechanism, and the crucible rotation and lifting mechanism 17 are all located on the frame 1.

[0075] The measurement method of the fully automated adhesion index tester in this embodiment includes the following steps: S1: The crucible rotation and lifting mechanism 17 rotates, causing the crucible 99 above it to move between the first feeding and weighing mechanism 18 and the anthracite feeding mechanism 15. The crucible rotation and lifting mechanism 17 descends, causing the crucible 99 to fall above the first feeding and weighing mechanism 18. After the anthracite feeding mechanism 15 quantitatively dispenses anthracite into the crucible 99, the crucible rotation and lifting mechanism 17 rises. S2: The crucible rotation and lifting mechanism 17 continues to rotate, causing the crucible 99 above it to move between the second feeding and weighing mechanism 19 and the test coal feeding mechanism 14. The crucible rotation and lifting mechanism 17 descends, causing the crucible 99 to fall above the second feeding and weighing mechanism 19. After the test coal feeding mechanism 14 quantitatively drops test coal into the crucible 99, the crucible rotation and lifting mechanism 17 rises. S3: The crucible rotation and lifting mechanism 17 continues to rotate to the gripping position of the robotic arm 7; S4: The robotic arm 7 grabs the crucible 99 and sends the crucible 99 containing anthracite and test coal to the subsequent stirring mechanism 3, coking pre- and post-coking treatment mechanism 4, pressure device 10, heating mechanism 5, cooling chamber 12, drum mechanism 6, screening mechanism 9 and weighing balance 8 for post-processing. Finally, the caking index is calculated based on the weighing results.

[0076] In this embodiment, the stirring mechanism 3 and the pre- and post-coking processing mechanism 4 are all fixed on the frame 1 and arranged around the robot arm 7. The robot arm 7 is responsible for grabbing and flipping the crucible 99 or sieve cup and moving it to each mechanism; the bottle-laying mechanism 16 is responsible for carrying the coal bottles 1601 for various test coals, and the test coal feeding mechanism 14 is responsible for grabbing the coal bottles 1601 from the bottle-laying mechanism 16 and can realize the opening of the coal bottles 1601, the feeding of test coal, and the weighing. The anthracite feeding mechanism 15 is responsible for the feeding and weighing of standard anthracite. The crucible rotation and lifting mechanism 17 can realize the rotation and lifting functions, cooperate to complete the weighing, and can store empty crucibles 99 or crucibles 99 containing coal weighed according to the ratio after the test, while rotating to the grabbing position of the robot arm 7. The stirring mechanism 3 is responsible for stirring the sample; the pre- and post-coking processing mechanism 4 is responsible for the pre-coking processing of the sample and the post-coking processing; the heating mechanism 5 is responsible for sending the sample into the heating furnace for heating and coking, taking out the sample and cooling it. The drum mechanism 6 is responsible for the sample drum test; the sieving mechanism 9 is responsible for sieving and waste collection; the weighing balance 8 is responsible for weighing the total mass after coking and the mass after the first and second sieving; the pressure device 10 is responsible for the static pressure of the sample (pressure 6 kg, time 30 s); to further improve work efficiency, this embodiment also includes a cooling chamber 12 to reduce experimental time, and is equipped with a dual drum (or more than two drums), dual agitators (or more than two agitators), dual heating furnaces (or more than two heating furnaces), sharing a single robotic arm 7. To clean the inside of the machine and reduce the impact of dust accumulation on the equipment, this embodiment also includes a dust removal system 13.

[0077] The specific structure and operating principle of the above-mentioned stirring mechanism 3, coking pre- and post-coking processing mechanism 4, pressure device 10, heating mechanism 5, drum mechanism 6, screening mechanism 9, robotic arm 7 and weighing balance 8 can be found in the prior art (CN117347647A), and will not be repeated here.

[0078] More specifically, the experimental steps for determining the adhesion index are as follows: 1. Place the coal cylinder 1601 or the cylinder tray 1602 onto the cylinder placement mechanism 16 (if there is an automated network, connect to the conveying system interface of the coal cylinder 1601 to automatically receive the coal cylinder 1601).

[0079] 2. Anthracite weighing: The anthracite feeding mechanism 15, together with the crucible rotation and lifting mechanism 17 and the first feeding and weighing mechanism 18, performs anthracite feeding and weighing.

[0080] 3. Test coal weighing: The capping and gripping mechanism 141 of the test coal feeding mechanism 14 grips the coal dispensing bottle 1601 from the bottle dispensing mechanism 16 and puts it into the test coal clamping and feeding mechanism 142. It works in conjunction with the crucible rotation and lifting mechanism 17 and the second feeding and weighing mechanism 19 to weigh the test coal.

[0081] 4. Stirring: such as Figure 21 As shown, the weighed crucible 99 is picked up from the crucible tray 1701 of the crucible rotation and lifting mechanism 17 by the robotic arm 7 and transferred to the stirring mechanism 3, where the stirring mechanism 3 thoroughly stirs the coal in the crucible 99.

[0082] 5. Coking preparation work such as leveling, pressing, placing in briquette, and covering the crucible: The robot arm 7 transports the mixed crucible 99 to the pre- and post-coking processing unit 4. Through the suction cup device and pressing device of the turntable part of the pre- and post-coking processing unit 4, the coal sample is leveled, pressed, placed in briquette, and the crucible is covered, etc., to prepare for coking.

[0083] 6. Static pressure: The crucible 99, which has been loaded with pressure blocks and covered, is transported to the pressure device 10 by the robotic arm 7, and static pressure is applied for 30 seconds by the pressure device 10.

[0084] 7. Heating and coking: The robotic arm 7 transports the statically pressed crucible 99 to the heating furnace, and through the heating mechanism 5, the crucible 99 is sent into the furnace for heating and then removed from the furnace.

[0085] 8. Cooling: The robotic arm 7 transports the crucible 99 to the cooling chamber 12, where air cooling is used to shorten the cooling time.

[0086] 9. Crucible lid removal, pressing block removal, cleaning, and other post-coking operations: The cooled crucible 99 is then transported by the robot arm 7 to the pre- and post-coking processing mechanism 4. The pressing block is removed by the suction cup device, pressing device, and cleaning device of the turntable part of the pre- and post-coking processing mechanism 4, the crucible lid is removed, and the pressing block is cleaned.

[0087] 10. Weighing the total mass of coke residue: The robotic arm 7 transports the crucible 99 to the weighing balance 8 to complete the weighing of the total mass of coke residue.

[0088] 11. First drum experiment: The robotic arm 7 puts the coke residue in the crucible 99 into the drum, and the drum experiment is completed by the drum mechanism 6; this drum mechanism 6 has no door or cover structure, no drum pushing structure, and the structure is simple.

[0089] 12. First screening: After the drum test is completed for 5 minutes, the drum is rotated so that the opening faces downward. The coal slag enters the screen cup through the receiving hopper, and then the screening mechanism 9 uses a swing mechanism to achieve screening in a manner similar to manual screening. Unlike screening methods that use high-frequency principles such as vibration, this method does not damage the strength of the coke slag.

[0090] 13. First weighing: Completed using weighing balance 8; weigh the material on the sieve after the first drum test and sieving.

[0091] 14. Second drum experiment: The coke residue is put into the drum from the sieve cup by the robotic arm, which is completed by the drum mechanism 6.

[0092] 15. Second screening: As described above, this is completed by screening mechanism 9.

[0093] 16. Second weighing: Completed by weighing balance 8; weigh the material on the sieve after the second drum test and sieving.

[0094] 17. Calculation results.

[0095] 18. Pouring coal slag: The robotic arm 7 pours the coal slag from the sieve cup after the second weighing into the waste bin.

[0096] 19. Empty crucible 99 returns to crucible tray 1701: After the robot arm 7 puts the slag from crucible 99 into the rotating drum (after step 11), the robot arm 7 puts the empty crucible 99 back onto the crucible tray 1701 of the crucible rotation and lifting mechanism 17.

[0097] For details on steps 4-19 above, please refer to the prior art (CN117347647A), which will not be repeated here.

[0098] The above is the general procedure for measuring the adhesion index. It should be noted that many stations can operate in parallel. For example, after the first crucible 99 has finished stirring, the second crucible 99 can continue stirring. The second crucible 99 does not have to wait until the first crucible 99 has finished its experiment. Therefore, the robotic arm 7 can work as long as there is available time at each station. The specific work arrangement is determined and adjusted by the system. Similarly, the weighed crucibles can be continuously retrieved from the crucible rotation and lifting mechanism 17 for testing, while empty crucibles 99 are returned to the crucible tray 1701 after testing. This allows for the preparation of coal sample feeding and weighing, enabling 24-hour continuous operation without stopping the machine.

[0099] This embodiment of the automatic weighing and fully automated caking index tester eliminates the need for pre-experiment preparation, specifically the requirement to mix and weigh the special anthracite coal and test coal in a 5:1 or 3:3 ratio. It provides a foundation for automated networking of various indicators in the coal industry, eliminating the need for manual sample weighing and preparation. This automatic weighing and fully automated caking index tester achieves complete automation of the testing process (automation of pre-experiment preparation), featuring a simple structure, compact size, high reliability, high accuracy of test results, unattended operation, and high work efficiency.
