Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a thermal shock resistance testing device that prevents temperature cross-flow. Background Technology

[0002] Thermal shock resistance, also known as thermal stability, refers to the ability of a material and its products to resist damage under conditions of rapid temperature changes. When a material is subjected to drastic temperature changes, thermal stress is generated within the material due to the restriction of contraction or expansion. If the thermal stress exceeds the material's strength limit, it may lead to cracking, damage, and a reduction in mechanical strength. For refractory and ceramic materials, thermal shock resistance is an important performance indicator.

[0003] A thermal shock resistance testing device is disclosed in Chinese invention patent application with patent number "CN118483100A". This device includes two furnaces with different temperatures and is connected by a quartz tube, which allows the object to be tested to be quickly transferred between the two furnaces, preventing excessive heat loss and improving the effectiveness of the test.

[0004] While this approach does improve the effectiveness of the test, the small distance between the two furnaces causes the high-heat furnace to conduct heat to the low-heat furnace along the quartz tube, resulting in temperature cross-contamination and affecting the accuracy of the test results. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a thermal shock resistance testing device to prevent temperature cross-contamination. This solves the problem that when two furnaces are close together, the high-heat furnace will conduct heat along the quartz tube to the low-heat furnace, causing temperature cross-contamination and affecting the accuracy of the test results.

[0006] This utility model provides the following technical solution: a thermal shock resistance testing device for preventing temperature cross-flow, comprising a fixed platform and a quartz tube. The fixed platform has an internal cavity. Two sets of electric push rods are fixedly connected to the bottom wall of the internal cavity of the fixed platform. A support plate is movably installed between the top ends of the two sets of electric push rods. A first furnace body and a second furnace body are fixedly connected to the upper surface of the support plate. Both the first furnace body and the second furnace body have furnace cavities inside. The quartz tube is installed in the furnace cavities of the first furnace body and the second furnace body. At least one end of the quartz tube can be opened to form a feeding port. The interior of the quartz tube forms a channel for material to transfer between the two furnace cavities. Two heat insulation components are installed inside the quartz tube.

[0007] Preferred technical solution 1: The heat insulation component includes a connecting rod, one end of which is provided with a closed heat insulation sheet group, and the other end of which is provided with a notched heat insulation sheet group, and the two notched heat insulation sheet groups in the two heat insulation components are adjacent to each other.

[0008] Preferred technical solution 2: Each of the closed heat insulation sheet groups and each of the notched heat insulation sheet groups includes at least two heat insulation sheets.

[0009] Preferred technical solution 3: The heat insulation sheet is made of 310s stainless steel, which can withstand high temperatures up to 1150℃.

[0010] Preferred technical solution four: The quartz tube is provided with a material receiving trough, the material receiving trough is located in the furnace cavity, the material receiving trough is formed by the downward indentation of the lower wall of the quartz tube, and the material receiving trough can be used for material to fall into.

[0011] Preferred technical solution five: There are two material containers, which are located in the furnace cavities of the first furnace body and the second furnace body, respectively, and the sidewalls of the material containers smoothly transition to the lower wall of the quartz tube.

[0012] Preferred technical solution six: Two rotating fulcrum rods are fixedly connected to the upper surface of the fixed platform, and the two sides of the support plate are rotatably connected to the two rotating fulcrum rods.

[0013] Preferred technical solution seven: The lower surface of the fixed platform is fixedly connected to four corners with legs, and the bottom of each leg is fixedly connected to a rubber pad.

[0014] Preferred technical solution eight: Three support rods are fixedly connected to the upper surface of the support plate, and all three support rods are fixedly connected to the quartz tube.

[0015] Preferred technical solution nine: The surfaces of both the first furnace body and the second furnace body are coated with a heat-insulating coating and a rust-proof coating.

[0016] Compared with existing technologies, this utility model provides a thermal shock resistance testing device to prevent temperature cross-flow, which has the following beneficial effects: In use, the notched insulation plate assembly is first inserted into the quartz tube with the notch facing upwards. Then, the test neutron absorbing ball is placed into the quartz tube, where it is blocked by the notched insulation plate assembly. Next, the closed insulation plate assembly is completely inserted into the quartz tube. The insulation assembly is rotated so that the notch of the notched insulation plate assembly faces downwards, and the other end of the quartz tube is also inserted into the insulation assembly. With the help of an electric push rod, the furnace body and quartz tube are tilted to one side, allowing the neutron absorbing ball to be heated in one furnace body. Then, the support plate is tilted to quickly transfer the neutron absorbing ball to another furnace with a different temperature for testing. A hook (not shown in the figure) is fixed to the rear end of the closed insulation plate assembly at the quartz tube opening to prevent the insulation assembly from going further in. The end of the notched insulation plate assembly should be positioned between the two furnace bodies to effectively isolate the two furnace bodies and prevent temperature cross-flow.

[0024] Please see Figure 1-6 ,

[0025] Example 1: A thermal shock resistance testing device for preventing temperature cross-flow includes a fixed platform 1 and a quartz tube 6. The fixed platform 1 has an internal cavity. Two sets of electric push rods 2 are fixedly connected to the bottom wall of the internal cavity of the fixed platform 1. A support plate 3 is movably installed between the top ends of the two sets of electric push rods 2. A first furnace body 4 and a second furnace body 5 are fixedly connected to the upper surface of the support plate 3. Both the first furnace body 4 and the second furnace body 5 have furnace chambers inside. The quartz tube 6 is installed in the furnace chambers of the first furnace body 4 and the second furnace body 5. At least one end of the quartz tube 6 can be opened to form a feeding port. The interior of the quartz tube 6 forms a channel for material to transfer between the two furnace chambers. Two heat insulation components are installed inside the quartz tube 6.

[0026] Example 2: The difference between this example and Example 1 is that the heat insulation component includes a connecting rod 7, one end of the connecting rod 7 is provided with a closed heat insulation sheet group 8, and the other end of the connecting rod 7 is provided with a notched heat insulation sheet group 9. The two notched heat insulation sheet groups 9 in the two heat insulation components are adjacent to each other, which can effectively prevent the occurrence of temperature cross-contamination.

[0027] Example 3: The difference between this example and Example 1 is that each closed heat insulation sheet group 8 and each notched heat insulation sheet group 9 includes at least two heat insulation sheets, which makes the anti-temperature cross-flow effect better.

[0028] Example 4: The difference between this example and Example 1 is that the heat insulation sheet is made of 310s stainless steel, which can withstand high temperatures up to 1150℃, making the heat insulation sheet sturdy, durable, and with good high-temperature resistance.

[0029] Example 5: The difference between this example and Example 1 is that the quartz tube 6 is provided with a material container, which is located in the furnace cavity. The material container is formed by the downward indentation of the lower wall of the quartz tube 6. The material container allows materials to fall into it. When the materials move to the material container, they fall into it, which can ensure that the materials are transferred to the furnace cavity and reduce the difficulty of operation.

[0030] Example 6: The difference between this example and Example 1 is that there are two material containers, which are located in the furnace cavities of the first furnace body 4 and the second furnace body 5, respectively. The side walls of the material containers and the lower wall of the quartz tube 6 are smoothly inclined. In the test scenario of repeated temperature changes, the material needs to be transferred back and forth between the two furnace cavities. Setting up two material containers and designing the material containers as sliding in and sliding out structures can effectively adapt to this scenario.

[0031] Example 7: The difference between this example and Example 1 is that two rotating fulcrum rods 10 are fixedly connected to the upper surface of the fixed platform 1, and the two sides of the support plate 3 are rotatably connected to the two rotating fulcrum rods 10, which can support the first furnace body 4 and the second furnace body 5, and facilitate the tilting of the support plate 3.

[0032] Example 8: The difference between this example and Example 1 is that the four corners of the lower surface of the fixed platform 1 are fixedly connected with legs, and the bottom of each leg is fixedly connected with a rubber pad, making the whole device more stable.

[0033] Example 9: The difference between this example and Example 1 is that three support rods are fixedly connected to the upper surface of the support plate 3, and all three support rods are fixedly connected to the quartz tube 6, making the quartz tube more stable.

[0034] Example 10: The difference between this example and Example 1 is that the surfaces of the first furnace body 4 and the second furnace body 5 are both coated with a heat-insulating coating and a rust-proof coating, which makes the heat-insulating effect of the first furnace body 4 and the second furnace body 5 good and prevents rusting.

[0035] In summary, this thermal shock resistance testing device for preventing temperature cross-flow involves first inserting the notched insulation plate assembly 9 into the quartz tube with the notch facing upwards. Then, the test neutron absorbing ball is placed into the quartz tube, where it is blocked by the notched insulation plate assembly 9. Next, the sealed insulation plate assembly 8 is completely inserted into the quartz tube 6. The insulation assembly is rotated so that the notch of the notched insulation plate assembly 9 faces downwards, and the other end of the quartz tube 6 is also inserted into the insulation assembly. With the help of the electric push rod 2, the furnace body and the quartz tube 6 are tilted to one side, allowing the neutron absorbing ball to be heated in one furnace body. Then, the support plate 3 is tilted to quickly transfer the neutron absorbing ball to another furnace with a different temperature, thus achieving the test. The rear end of the sealed insulation plate assembly 8 has a hook fixed to the opening of the quartz tube 6 (not shown in the diagram) to prevent the insulation assembly from going further in. The end of the notched insulation plate assembly 9 should be positioned between the two furnace bodies to effectively isolate the two furnace bodies and prevent temperature cross-flow.
