Description

Technical Field

[0001] This application belongs to the field of sintering cup testing technology, and particularly relates to a sintering cup. Background Technology

[0002] The sintering cup test is used to simulate ore sintering in order to obtain relevant ore sintering parameters. During the sintering cup test, a sintering cup is used to load the mixture for sintering.

[0003] Currently, when a sintering cup is loaded with a mixture such as ore, the mixture shrinks after sintering during the testing process. This results in a strong edge effect between the mixture and the sintering cup, which affects process parameters and leads to less than ideal accuracy in the test results. Utility Model Content

[0004] This application aims to at least partially solve the technical problem of the insufficient accuracy of sintering cup test results. To this end, this application provides a sintering cup.

[0005] This application provides a sintering cup, comprising:

[0006] The cup body has a cup hole;

[0007] A sintered grate bar is provided at the end of the cup body away from the cup mouth, and the gap of the sintered grate bar communicates with the cup hole;

[0008] A fabric tube is movably inserted into a cup hole, and a sealing groove is formed between the outer peripheral wall and the cup hole, the sealing groove being configured to be filled with powder to form a powder filling layer.

[0009] In some or more embodiments, the sealing groove is configured to be filled with magnetic powder to form a magnetic powder filling layer.

[0010] In some or more embodiments, the axial length of the fabric tube is greater than the depth of the cup orifice, and the sealing groove is configured to fill the powder to form the powder filling layer.

[0011] In some or more embodiments, the cup hole is a cylindrical hole, the fabric tube is coaxial with the cup hole, and the fabric tube is movably inserted into the cup hole along the axial direction of the cup hole.

[0012] In some or more embodiments, the fabric tube includes:

[0013] The tube body is movably inserted into the cup hole, and the sealing groove is formed between the outer peripheral wall and the cup hole;

[0014] The annular portion is coaxially connected to one end of the tube body and spaced apart from the sealing groove.

[0015] In some or more embodiments, the annular portion is conical, and the smaller diameter end of the annular portion is coaxially connected to the tube body.

[0016] In some or more embodiments, the cup body is a rotating structure, and the outer diameter of the annular portion is larger than the outer diameter of the cup body.

[0017] In some or more embodiments, the outer peripheral wall of the fabric tube is provided with at least two support protrusions, the side of the support protrusions away from the fabric tube abutting against the wall of the cup hole.

[0018] In some or more embodiments, at least two of the support protrusions are evenly spaced along the circumference of the fabric tube.

[0019] In some or more embodiments, the cup body has a cup hole and a mounting hole communicating with the cup hole at both ends, and the sintered grate bar includes:

[0020] An annular body is coaxially connected to the wall of the mounting hole;

[0021] Multiple strip-shaped portions are connected side by side to the inner wall of the annular body, and a gap is formed between two adjacent strip-shaped portions to communicate with the cup hole.

[0022] The beneficial effects provided by one or more embodiments of this application are as follows:

[0023] The sintering cup has an orifice in its body for placing ore and other mixtures for sintering. Sintering grates are located at the end of the cup body furthest from the opening, and the gaps in the grates connect to the orifice. The grates provide ventilation for the ore and other mixtures during sintering, ensuring the normal operation of the sintering cup test. A feeding tube is movably inserted into the orifice. The ore and other mixtures can be placed in the feeding tube and supported on the sintering grates. A sealing groove is formed between the outer wall of the feeding tube and the orifice. Powder fills the sealing groove to form a powder filling layer, which is isolated from the ore and other mixtures by the feeding tube. After the material is laid, when a sintering cup test is required, the material laying tube can be pulled out. The powder filling layer will fill the space between the columnar ore mixture and the cup hole wall, achieving automatic sealing between the powder filling layer and the cup hole wall. There are almost no gaps between the mixture and the cup hole wall. Even after the mixture is sintered, the powder filling layer can continue to seal between the mixture and the cup hole wall, effectively reducing the possibility of gaps between the mixture and the cup hole wall, thereby reducing the edge effect caused by gaps, ensuring the uniformity of the ore mixture during the sintering process, and improving the accuracy of the parameters and results obtained from the sintering cup test. This solves, to some extent, the technical problem of the unsatisfactory accuracy of the sintering cup test results. Attached Figure Description

[0036] In related technologies, mixtures of ores are placed in a sintering cup during sintering tests, where they are ignited and sintered. However, insufficient contact between the mixture and the inner wall of the sintering cup, coupled with shrinkage of the mixture after sintering, leads to gaps between the mixture and the inner wall. These gaps cause the portion of the mixture closer to the inner wall to sinter faster, at a lower temperature, and produce lower-quality products during evacuated sintering compared to the portion closer to the center – a phenomenon known as the edge effect in sintering cup tests. This results in less-than-ideal accuracy in sintering cup test results, presenting a technical problem. This application provides a sintering cup that at least partially addresses the aforementioned technical problems.

[0037] The present application will now be described in conjunction with the accompanying drawings:

[0038] Figure 1 This application shows a schematic diagram of the structure of a sintering cup in some or certain embodiments. Figure 2 A top view of a sintering cup is shown in some or certain embodiments of this application. Figure 3 A cross-sectional view of a cup body is shown in some or certain embodiments of this application, with reference to... Figures 1-3 This application provides a sintering cup, comprising:

[0039] The cup body 1 has a cup hole 11.

[0040] The sintered grate bar 2 is located at the end of the cup body 1 away from the cup mouth, and the gap 21 of the sintered grate bar 2 is connected to the cup hole 11.

[0041] The fabric tube 3 is movably inserted into the cup hole 11, and a sealing groove 4 is formed between the outer peripheral wall and the cup hole 11. The sealing groove 4 is configured to be filled with powder to form a powder filling layer 5.

[0042] The cup body 1 of the sintering cup has a cup hole 11 for placing a mixture of ore and other materials for sintering. The sintering grate 2 is located at the end of the cup body 1 away from the cup opening, and the gap 21 of the sintering grate 2 connects to the cup hole 11. The sintering grate 2 can meet the ventilation requirements of the mixture of ore and other materials during the sintering process, ensuring the normal operation of the sintering cup test. The feeding tube 3 is movably inserted into the cup hole 11. The mixture of ore and other materials can be placed in the feeding tube 3 and supported on the sintering grate 2. A sealing groove 4 is formed between the outer peripheral wall of the feeding tube 3 and the cup hole 11. Powder is filled in the sealing groove 4 to form a powder filling layer 5. The powder filling layer 5 is isolated from the mixture of ore and other materials by the feeding tube 3. After the material is laid, when a sintering cup test is required, the material laying tube 3 can be pulled out. The powder filling layer 5 will fill the space between the columnar ore mixture and the hole wall of the cup 11, achieving automatic sealing between the powder filling layer 5 and the hole wall of the cup 11. There are almost no gaps 21 between the mixture and the hole wall of the cup 11. Even after the mixture is sintered, the powder filling layer 5 can continue to seal between the mixture and the hole wall of the cup 11, effectively reducing the possibility of gaps 21 between the mixture and the hole wall of the cup 11, thereby reducing the edge effect caused by gaps 21, ensuring the uniformity of the ore mixture during the sintering process, and making the sintering state of the ore mixture closer to the uniform sintering state of the ore in the actual sintering process, thereby improving the accuracy of the parameters and results obtained from the sintering cup test, and to a certain extent solving the technical problem that the accuracy of the sintering cup test results is not ideal.

[0043] It should be noted that the mouth of the cup body 1 is the opening of the cup hole 11. Figure 1 The image shows the state in which the sealing groove 4 is filled with powder and forms a powder filling layer 5. Figure 2 The sealing groove 4 is not filled with powder. The powder filled in the sealing groove 4 can be a powder with a certain particle size that will not affect the parameters and sintering results of the mixture after sintering. The outer peripheral wall of the feeding tube 3 is the peripheral wall with a larger diameter, and the hole wall corresponding to the inner hole of the feeding tube 3 is the inner peripheral wall of the feeding tube 3.

[0044] In some or all embodiments, the sealing groove 4 is configured to be filled with magnetic powder to form a magnetic powder filling layer 5.

[0045] The sealing groove 4 is filled with magnetic powder to form a magnetic powder filling layer 5. The magnetic powder can also fill the space between the mixture and the hole wall of the cup hole 11. After the mixture is sintered, magnetic equipment or tools can be used to extract the magnetic powder, complete the recovery of the magnetic powder and reduce the powder that will be added after the mixture is sintered. This is more environmentally friendly and helps to improve the accuracy of the test results after the mixture is sintered.

[0046] In some or more embodiments, the particle size of the powder filling the sealing groove 4 can be 50 mesh to 110 mesh. The filling effect is good and it is easy to recycle.

[0047] In some or more embodiments, the particle size of the powder filling the sealing groove 4 may also be less than 50 mesh. This can also achieve a good seal.

[0048] In some or more embodiments, the axial length of the fabric tube 3 is greater than the depth of the cup hole 11, and the sealing groove 4 is configured to be filled with powder to form a powder filling layer 5.

[0049] The axial length of the feeding tube 3 is greater than the depth of the cup hole 11. The feeding tube 3 can extend out of the cup hole 11. The part of the feeding tube 3 extending out of the cup hole 11 can play a certain guiding and limiting role. The powder is filled into the sealing groove 4 along the part of the feeding tube 3 extending out of the cup hole 11 and can fill the sealing groove 4. The height to which the powder can fill can be increased. Therefore, during the sintering and exhaust process of the mixture, and when the mixture shrinks during sintering, more powder can fill the space between the mixture and the hole wall of the cup hole 11. This helps to reduce the possibility of edge effects during sintering and improve the accuracy of the final test results obtained from the sintering cup test.

[0050] In some embodiments, the axial length of the fabric tube 3 may be 5–20 cm longer than the depth of the cup hole 11. This results in more accurate test results and improves the overall accuracy of the test results.

[0051] In some or more embodiments, the fabric distribution tube 3 may also be a tubular structure, and the fabric distribution tube 3 may be made of aluminum or aluminum alloy. This facilitates fabrication and provides a long service life.

[0052] In some or more embodiments, the cup hole 11 is a cylindrical hole, the fabric tube 3 is coaxial with the cup hole 11, and the fabric tube 3 is movably inserted into the cup hole 11 along the axial direction of the cup hole 11.

[0053] If the sealing groove 4 formed between the feeding tube 3 and the cup hole 11 can be controlled to be a ring shape with uniform thickness, the powder filled in the sealing groove 4 will also be more uniform, and the thickness of the powder filling layer 5 formed will also be more uniform. After the feeding tube 3 is pulled out, the powder can uniformly fill the space between the hole wall of the cup hole 11 and the mixture. The mixture will have a better sealing effect at the edge during the subsequent sintering process, the sintering will be more uniform, and the test results will be more accurate.

[0054] In some or all embodiments, the cross-section of the cup hole 11 may also be elliptical or rectangular, and the cloth tube 3 may be movable along the axial direction of the cup hole 11. This can be achieved by setting a corresponding guide mechanism or support block on the hole wall of the cloth tube 3 or the cup hole 11.

[0055] Figure 4 This application shows a schematic diagram of the structure of a fabric tube in some or certain embodiments. Figure 5 A top view of a fabric tube in some or certain embodiments of this application is shown, with reference to... Figure 4 , 5 In some or more embodiments, the fabric tube 3 includes:

[0056] The tube body 31 is movably inserted into the cup hole 11, and a sealing groove 4 is formed between the outer peripheral wall and the cup hole 11.

[0057] The annular portion 32 is coaxially connected to one end of the tube body 31 and spaced apart from the sealing groove 4.

[0058] One end of the tube body 31 is coaxially connected to the annular part 32. The annular part 32 can facilitate the entry of the mixture into the feeding tube 3, which is beneficial to improving the sintering results and feeding efficiency.

[0059] In some embodiments, the annular portion 32 is conical, and the smaller diameter end of the annular portion 32 is coaxially connected to the tube body 31. This facilitates material feeding and prevents the mixture from entering the sealing groove 4, which is beneficial for improving sintering results and feeding efficiency.

[0060] In some or more embodiments, the cup body 1 has a rotating structure, and the outer diameter of the annular portion 32 is larger than the outer diameter of the cup body 1. This is beneficial for improving the material distribution efficiency and can effectively prevent the mixed material from entering the sealing groove 4.

[0061] In some or more embodiments, the outer peripheral wall of the fabric tube 3 is provided with at least two support protrusions 33, and the side of the support protrusions 33 away from the fabric tube 3 abuts against the wall of the cup hole 11.

[0062] The support protrusion 33 can support the cloth tube 3, which facilitates the stable movement of the cloth tube 3 relative to the cup hole 11 of the cup body 1, and also helps to stably fill the powder in the sealing groove 4 to form the powder filling layer 5.

[0063] In some or more embodiments, at least two support protrusions 33 are evenly spaced along the circumference of the feeding tube 3. The feeding tube 3 can move stably along the axial direction of the cup hole 11, and the thickness of the sealing groove 4 formed between the outer peripheral wall of the feeding tube 3 and the hole wall of the cup hole 11 is also relatively uniform, which is beneficial to ensure that the powder filling layer 5 can uniformly and effectively seal the mixture.

[0064] Figure 6 This application shows a schematic diagram of the structure of a sintered grate bar in some or certain embodiments. (Refer to...) Figure 3 , 6 In some or more embodiments, the cup body 1 has a cup hole 11 and a mounting hole 12 communicating with the cup hole 11 at both ends, and the sintered grate bar 2 includes:

[0065] The annular body 22 is coaxially connected to the wall of the mounting hole 12.

[0066] Multiple strip-shaped portions 23 are connected side by side to the inner wall of the annular body 22, and a gap 21 connecting the cup hole 11 is formed between two adjacent strip-shaped portions 23.

[0067] The main body has cup holes 11 and mounting holes 12 connecting the cup holes 11 at both ends. The mounting holes 12 can be used to install sintering grate bars 2, which facilitates ventilation during the sintering process. The sintering grate bar 2 includes an annular body 22 coaxially connected to the wall of the mounting hole 12. The annular body 22 facilitates the connection between the sintering grate bar 2 and the cup body 1, and also provides some support, increasing the position where the feeding tube 3 can be supported. This allows a sealing groove 4 for filling powder to be formed between the outer peripheral wall of the feeding tube 3 and the wall of the cup hole 11. The strip-shaped parts 23 connected side by side to the inner wall of the annular body 22 can form a gap 21 connecting the cup hole 11, which provides ventilation space through the gap 21 of the sintering grate bar 2.
