[0042] Hereinafter, the exemplary embodiments of the present disclosure will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0043] As Figures 1 to 6As shown in the figure, a sintering cup 100 for experiments is provided according to the first aspect of the embodiments of the present disclosure, including: a support part 110, formed with a ventilation opening 1101, and the ventilation opening 1101 is used to communicate with a air supply device 300; a transparent tube 120, one end of the transparent tube 120 is arranged on the support part 110, the transparent tube 120 is formed with a plurality of accommodation spaces 1201, the accommodation spaces 1201 extend along the axial direction of the transparent tube 120, and the plurality of accommodation spaces 1201 communicate with the ventilation opening 1101; wherein, the plurality of accommodation spaces 1201 are arranged circumferentially along the transparent tube 120.

[0044] The sintering cup 100 for experiments provided by the embodiments of the present disclosure includes the aforementioned support part 110 and the aforementioned transparent tube 120. Based on the aforementioned settings, the sintering cup 100 for experiments can use the accommodation spaces 1201 of the transparent tube 120 to accommodate the materials to be sintered; the support part 110 can support and fix the transparent tube 120, thereby improving the position stability of the transparent tube 120 and the materials to be sintered, and the ventilation opening 1101 on the support part 110 can communicate between the accommodation spaces 1201 of the transparent tube 120 and the air supply device 300, so as to introduce hot air into the aforementioned accommodation spaces 1201 during the experiment, which is beneficial to ensuring the stable progress of the sintering process. The number of the aforementioned accommodation spaces 1201 is multiple, so that the sintering cup 100 for experiments can accommodate multiple groups of materials to be sintered during a single sintering experiment, facilitating the simultaneous sintering experiment of multiple groups of materials to be sintered. Furthermore, compared with the method of sintering the same material sequentially, on the one hand, the sintering cup 100 for experiments provided by the present disclosure is convenient for obtaining multiple groups of experimental results after a single sintering experiment, improving the experimental analysis efficiency, and can shorten the waiting time of the materials to be sintered for the sintering experiment after preparation, reducing the probability that the physical and chemical parameters of the materials to be sintered change significantly during the waiting process, which is beneficial to reducing the risk of large deviations between multiple groups of experimental results; on the other hand, since multiple groups of materials to be sintered are all located in the transparent tube 120, it can make the positions of multiple groups of materials to be sintered relatively close during the sintering experiment and can participate in the sintering process synchronously, thereby reducing the environmental differences between multiple groups of materials to be sintered during the sintering process and reducing the experimental result deviation caused by different sintering environments; based on this, the sintering cup 100 for experiments provided by the present disclosure is beneficial to improving the accuracy and credibility of the experimental results and providing reliable support for the analysis after the experiment. And, since the aforementioned multiple accommodation spaces 1201 are arranged circumferentially along the transparent tube 120 and the transparent tube 120 has good visibility, it is convenient for the experimenter to observe and compare the sintering processes of each group of materials by adjusting the relative orientation between himself and the transparent tube 120 during the experiment, and can facilitate the experimenter to observe the changes of each zone of the materials, which is beneficial for the experimenter to obtain more experimental data and conduct a more in-depth analysis.

[0045] It can be understood that when conducting sintering tests on the same kind of material sequentially in the traditional technology, the test personnel need to independently control the test parameters of different sintering tests, which easily leads to differences in the environmental parameters of the material to be sintered in different sintering tests. For example, differences are likely to occur in aspects such as ignition temperature, ignition negative pressure, and sintering negative pressure. Moreover, during the waiting process of the material to be sintered, changes in physical and chemical parameters are likely to occur. For example, parameters such as the moisture and temperature of the material are prone to change, thereby causing large deviations in the test results obtained from multiple sintering tests on the same kind of material. Compared with the method of conducting sintering tests on the same kind of material sequentially, the sintering cup 100 for experiments provided by the present disclosure facilitates obtaining multiple groups of test results after a single sintering test, improves the test analysis efficiency, and can shorten the waiting time of the material to be sintered after preparation for the sintering test, reducing the probability of significant changes in the physical and chemical parameters of the material to be sintered during the waiting process, which is beneficial to reducing the risk of large deviations between multiple groups of test results, can narrow the environmental differences of multiple groups of materials to be sintered during the sintering process, and reduce the test result deviations caused by different sintering environments.

[0046] It should be noted that Figure 6 The single straight line with a hollow arrow is used to schematically represent the transfer direction of the material during the sintering test, and the single straight line with a hollow arrow is used to schematically represent the flow direction of the hot air.

[0047] It can be understood that the sintering cup 100 for experiments provided by the embodiments of the present disclosure can be used as a component of the sintering test system. Taking the sintering cup 100 for experiments applied to Figure 6Taking the shown sintering test system as an example, the sintering test system may further include a mixing device 200, an air supply device 300, a crushing device 400, a blanking device 500 and a rotary screen device 600; the aforementioned air supply device 300 may include a fan, and the support portion 110 of the sintering cup 100 for testing may be fixedly arranged on the air box of the fan and the aforementioned ventilation port 1101 communicates with the air inlet of the fan. The connection between the support portion 110 and the aforementioned air box may be sealed with tape so that the fan can suck the gas in the accommodation space 1201 through the ventilation port 1101. The connection between the aforementioned transparent tube 120 and the support portion 110 may be a detachable connection relationship. During the test, according to the requirement of the number of test groups of the sintering test, the transparent tubes 120 corresponding to the number of accommodation spaces 1201 and the number of test groups may be selected, and the aforementioned transparent tubes 120 may be arranged on the aforementioned support portion 110. Heat insulation cotton may be arranged around the pipe section of the transparent tube 120 close to the support portion 110; the aforementioned mixing device 200 is used to mix the iron ore raw materials and additives to be tested and output the aforementioned sintering material in granular form. The parameters such as the particle size, moisture content, carbon content, etc. of the aforementioned sintering material may be set according to the test requirements and will not be limited here; the aforementioned sintering material may be filled in the aforementioned accommodation space 1201. During the test, fuel may also be accommodated in the accommodation space 1201 to provide the heat required for material sintering by the fuel. Correspondingly, during the sintering process, the aforementioned fuel may be ignited by a burner, and the air supply device 300 may be used to drive the hot air flow through the accommodation space 1201 to sinter the material in the accommodation space 1201. The parameters such as the ignition temperature, ignition negative pressure, sintering negative pressure, air volume, etc. during the test process may be set according to the test requirements and will not be limited here; after the sintering is completed, the sintering cup 100 for testing may be removed from the aforementioned air box, and the transparent tube 120 may be disassembled to take out the sintered ore; the aforementioned crushing device 400 may be used to crush the aforementioned sintered ore; the aforementioned blanking device 500 may be used to convey the crushed sintered ore to the rotary screen device 600; the aforementioned rotary screen device 600 is used to screen the crushed sintered ore.

[0048] It can be understood that the sintering material to be sintered can be roughly divided into five zones during the sintering process. The aforementioned five zones are respectively the sintered ore zone, the combustion zone, the drying and preheating zone, the over-wet zone and the raw material zone; based on the aforementioned settings, the sintering cup 100 for testing provided by the embodiments of the present disclosure can facilitate the test personnel to observe the change process of each zone of the material during the sintering process, measure the thickness of the combustion zone and the over-wet zone, and conduct a more in-depth analysis of the sintering process through the conditions of the combustion zone and the over-wet zone.

[0049] It can be understood that, in practical applications, the sintering cup 100 for experiments provided by the embodiments of the present disclosure can also be used for analyzing the influence of raw fuels on the combustion zone. For example, multiple groups of raw materials to be sintered with different raw fuels can be respectively placed in different accommodation spaces 1201 for sintering experiments, so as to facilitate comparing the differences in the combustion zones under different raw fuel conditions.

[0050] It can be understood that the aforementioned transparent tube 120 can be made of a temperature-resistant transparent material. Considering the temperature conditions of the sintering experiment, the temperature resistance of the aforementioned transparent tube 120 can be greater than or equal to 1200 °C. The aforementioned support portion 110 can be made of a metal material, for example, it can be made of an iron material.

[0051] It can be understood that the two ends of the transparent tube 120 in the axial direction can be open, and the accommodation space 1201 communicates between the two ends of the tube, so as to facilitate loading materials during the experiment, or connecting the ventilation opening 1101 and the accommodation space 1201 through the tube orifice. During the experiment, a bottom layer material can be provided at the bottom of the material to be sintered to prevent the material to be sintered from leaking out of the tube orifice, and the aforementioned bottom layer material has air permeability.

[0052] As Figures 2 to 4 shown, in some examples, the transparent tube 120 includes: a tube body 121; a plurality of partition plates 122 disposed inside the tube body 121, with the first end of the partition plate 122 connected to the inner peripheral wall of the tube body 121 and the second end of the partition plate 122 located at the axis position of the tube body 121; wherein, the partition plates 122 extend along the axial direction of the tube body 121, and the first ends of the plurality of partition plates 122 are arranged at intervals along the circumferential direction of the tube body 121, and the second ends of the plurality of partition plates 122 are connected to divide the interior of the tube body 121 into a plurality of accommodation spaces 1201.

[0053] In this technical solution, the transparent tube 120 can include the aforementioned tube body 121 and the aforementioned partition plates 122; based on the aforementioned settings, the transparent tube 120 can use the tube body 121 and a plurality of partition plates 122 to enclose a plurality of the aforementioned accommodation spaces 1201, so that the sintering cup 100 for experiments can accommodate multiple groups of materials to be sintered and synchronously conduct multiple groups of sintering experiments during a single sintering experiment, and can make the aforementioned accommodation spaces 1201 extend along the axial direction of the transparent tube 120 and be arranged along the circumferential direction of the transparent tube 120, thereby making multiple groups of materials to be sintered more regularly distributed inside the transparent tube 120, which is beneficial to reducing the environmental differences between multiple groups of materials to be sintered during the sintering process.

[0054] It can be understood that the number of the aforementioned partition plates 122 can be greater than or equal to two, and correspondingly, the number of the aforementioned accommodation spaces 1201 is the same as the number of the aforementioned accommodation spaces 1201. Exemplarily, the number of the aforementioned partition plates 122 and the aforementioned accommodation spaces 1201 can be, but are not limited to, 2, 3, 4, 5, etc.

[0055] As Figure 2 and Figure 4 shown, in some examples, the tube body 121 is circular tubular, and the first ends of the plurality of partition plates 122 are uniformly arranged along the circumferential direction of the tube body 121.

[0056] In this technical solution, the tube body 121 can be set to be circular tubular, and the first ends of the plurality of partition plates 122 are uniformly arranged along the circumferential direction of the tube body 121; based on the foregoing setting, the shape parameters of each accommodation space 1201 can be made consistent, which is beneficial to further reducing the environmental differences between multiple groups of materials to be sintered, and facilitating the multi-group sintering tests with equal amounts of materials, which is beneficial to further improving the accuracy and reliability of the test results and providing reliable support for the analysis after the test.

[0057] It can be understood that the first ends of the foregoing plurality of partition plates 122 being uniformly arranged along the circumferential direction of the tube body 121 means that the plurality of partition plates 122 are arranged at equal angular intervals along the circumferential direction of the tube body 121. Taking the number of the foregoing partition plates 122 being two as an example, the included angle between the two partition plates 122 can be 180°, so as to divide the inside of the tube body 121 into two identical accommodation spaces 1201; taking the number of the foregoing partition plates 122 being three as an example, the included angle between two adjacent partition plates 122 can be 120°, so as to divide the inside of the tube body 121 into three identical accommodation spaces 1201; and so on, without excessive enumeration here.

[0058] It can be understood that the two ends of the partition plate 122 in the axial direction of the tube body 121 are the third end and the fourth end respectively, the foregoing third end is flush with one end of the tube body 121 in the axial direction, and the fourth end is flush with the other end of the tube body 121 in the axial direction, so that the partition plate 122 can divide the two ends of the tube body 121 into a plurality of pipe orifice intervals corresponding one by one to the accommodation spaces 1201, and the shape parameters of the plurality of pipe orifice intervals are the same, which is further beneficial to ensuring the air volume consistency of each accommodation space 1201 during the sintering process.

[0059] In some examples, the tube body 121 is coaxially arranged with the ventilation opening 1101.

[0060] In this technical solution, the tube body 121 can be set to be coaxially arranged with the ventilation opening 1101; based on the foregoing setting, when the tube body 121 is circular tubular and the first ends of the plurality of partition plates 122 are uniformly arranged along the circumferential direction of the tube body 121, the conduction area between the ventilation opening 1101 and each accommodation space 1201 can be made consistent, which is further beneficial to ensuring the air volume consistency of each accommodation space 1201 during the sintering process and reducing the test result deviation caused by different sintering environments.

[0061] It can be understood that the foregoing ventilation opening 1101 is in the shape of a solid of revolution.

[0062] In some examples, the partition 122 and the tube body 121 are of an integral structure; alternatively, the partition 122 is detachably connected to the tube body 121.

[0063] In this technical solution, the partition 122 and the tube body 121 can be set to be of an integral structure, thereby reducing the assembly difficulty between the partition 122 and the tube body 121, facilitating the manufacture of the transparent tube 120, reducing the connection gap between the partition 122 and the tube body 121, reducing the probability of communication between multiple accommodation spaces 1201, and being beneficial to preventing the mixing of materials between multiple accommodation spaces 1201, providing further guarantee for the accuracy of test results.

[0064] Or, the partition 122 can be detachably connected to the tube body 121, thereby facilitating the independent cleaning and maintenance of the tube body 121 and the partition 122, improving the cleaning and maintenance convenience of the transparent tube 120, and reducing the maintenance cost of the transparent tube 120.

[0065] As Figure 1 and Figure 3 shown, in some examples, the tube body 121 is formed with a plurality of scale lines 1202, and the plurality of scale lines 1202 are uniformly arranged along the axial direction of the tube body 121.

[0066] In this technical solution, the tube body 121 can be formed with a plurality of the foregoing scale lines 1202; based on the foregoing setting, it is convenient for the operator to measure the thickness of each zone of the material during the sintering process, improves the use convenience of the sintering cup 100 for testing, and is beneficial for the tester to obtain more test data and conduct more in-depth analysis.

[0067] Exemplarily, the interval distance between two adjacent scale lines 1202 can be, but is not limited to, 10 mm.

[0068] In some examples, the transparent tube 120 is made of quartz material.

[0069] In this technical solution, the transparent tube 120 can be made of quartz material; based on the foregoing setting, the heat resistance performance of the transparent tube 120 can be improved, which is beneficial to reducing the risk of damage to the transparent tube 120 during the sintering process.

[0072] It can be understood that, based on the aforementioned settings of this technical solution, when the aforementioned pipe body 121 is circular tubular and the first ends of the plurality of aforementioned partition plates 122 are evenly arranged along the circumference of the pipe body 121, the conduction area between the ventilation opening 1101 and each accommodating space 1201 can be made consistent, which is beneficial to ensuring the air volume consistency of each accommodating space 1201 during the sintering process and reducing the deviation of test results caused by different sintering environments.

[0073] It can be understood that during the test process, heat insulation cotton can be filled between the fixed pipe 113 and the transparent pipe 120 to prevent the transparent pipe 120 from dissipating heat quickly.

[0075] In this technical solution, the support part 110 may further include the aforementioned lifting lug; based on the aforementioned settings, it is convenient to hoist and transfer the support part 110 during use, which is beneficial to further improving the convenience of use of the sintering cup 100 for experiments.

[0076] It can be understood that the lifting lug is located outside the fixed pipe 113.

[0077] In some feasible examples, the number of lifting lugs is multiple, and the multiple lifting lugs are evenly arranged around the fixed pipe 113.

[0078] In some feasible examples, the outer diameter of the aforementioned pipe body 121 is greater than or equal to 300 mm. Exemplarily, it can be, but is not limited to, 310 mm, 320 mm, 350 mm, etc.
