Abstract
Description
Technical Field
[0001] This utility model belongs to the field of quartz crucible testing technology, specifically a high-temperature resistance testing device for quartz crucibles. Background Technology
[0002] Quartz crucibles are a key piece of equipment widely used in high-temperature environments, mainly in semiconductor, photovoltaic, metallurgy, and chemical industries. Because they need to operate under extreme temperature conditions, high-temperature testing is an important step in ensuring their performance and safety, so as to ensure that the crucible will not crack, deform or leak at high temperatures and avoid production accidents.
[0003] Traditionally, high-temperature testing requires staff to manually push the crucible into a high-temperature furnace for heating. This not only increases the workload of the staff but also easily leads to injury, thus affecting the actual testing efficiency. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a high-temperature resistance testing device for quartz crucibles, which solves the problem that in traditional high-temperature testing, workers manually push the crucible into a high-temperature furnace for heating, which not only increases the workload of workers but also easily leads to injury to workers, thus affecting the actual testing efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistance testing device for quartz crucibles, comprising a base, a plurality of casters mounted below the base, a heating tank fixedly mounted above the base, a controller mounted on one side of the heating tank, a hollow plate connected to the other side of the heating tank, an insulation layer provided inside the heating tank, a heating wire connected inside the heating tank, and a motor fixedly mounted below the hollow plate;
[0006] The motor output shaft is connected to a threaded screw, and a movable plate is threadedly installed on the threaded screw. A sealing end cover is connected to the movable plate, and a connecting plate is connected below the sealing end cover. Multiple partitions are connected inside the connecting plate, and an adjusting screw is threadedly connected to the partition. Contact blocks are connected to both ends of the adjusting screw.
[0007] As a further embodiment of this utility model: there are four universal wheels arranged in a rectangular array, and the threaded screw is rotatably connected inside the hollow plate.
[0008] As a further embodiment of this utility model: the heating wire is specifically disposed between the inner wall of the heating tank and the insulation layer, the insulation layer is specifically ceramic fiber, and the heating wire has a spiral design with both ends electrically connected to the controller.
[0009] As a further embodiment of this utility model: there are three partitions in total, and the three partitions divide the connecting plate into three areas at equal intervals, and the contact block is provided with anti-slip texture.
[0010] As a further embodiment of this utility model: a limiting block is connected to one inner wall of the hollow plate, and the movable plate slides inside the hollow plate and contacts the inner wall of the hollow plate.
[0011] As a further embodiment of this utility model: a limiting groove is provided on the movable plate, and the limiting block slides within the limiting groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This high-temperature resistance testing device for quartz crucibles, consisting of a motor, threaded screw, movable plate, sealing end cap, casters, limiting block, and limiting groove, allows the operator to place the crucible on the partition plate and then start the motor to rotate the threaded screw. As the screw rotates, the movable plate, which is threaded into the screw, slides within the hollow plate, causing the limiting block to slide within the limiting groove. This causes the movable plate to pull the sealing end cap down, propelling the connecting plate into the heating tank, thus pushing the crucible into the heating tank to complete the feeding process. This eliminates the need for manual operation, reducing workload and improving testing safety. The casters also facilitate easy movement of the testing device by the operator.
[0014] 2. This high-temperature resistance testing device for quartz crucibles, by setting up partitions, adjusting screws, and contact blocks, allows the operator to invert the crucible to be tested onto the partitions. Then, by turning the adjusting screw at one end of the contact block, the operator causes the contact block at the other end to contact the inner wall of the crucible, thereby positioning the crucible and preventing it from sliding. If the surface of the crucible is smooth and prone to sliding, the crucible can be placed on the two partitions below, and the two adjusting screws can be turned to cause the two contact blocks to contact the outer and inner walls of the crucible simultaneously, thereby clamping and fixing the crucible.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a high-temperature resistance testing device for quartz crucibles, including a base 1, with multiple casters 2 installed below the base 1. There are four casters 2 in total, arranged in a rectangular array. A threaded screw 9 is rotatably connected to a hollow plate 5. Through the joint rolling of multiple casters 2, the operator can flexibly push the testing device to move, thereby improving the flexibility and practicality of the testing device.
[0022] A heating tank 3 is fixedly installed on the top of the base 1. A controller 4 is installed on one side of the heating tank 3, and a hollow plate 5 is connected to the other side of the heating tank 3. A limit block 16 is connected to the inner wall of one side of the hollow plate 5. The movable plate 10 slides inside the hollow plate 5 and contacts the inner wall of the hollow plate 5. Through the contact between the movable plate 10 and the inner wall of the hollow plate 5, the hollow plate 5 can restrict the movable plate 10, thereby preventing the movable plate 10 from rotating or tilting when moving, so that the movable plate 10 can move smoothly.
[0023] The heating tank 3 has an insulation layer 6 inside, and a heating wire 7 is connected inside the heating tank 3. The heating wire 7 is specifically located between the inner wall of the heating tank 3 and the insulation layer 6. The insulation layer 6 is made of ceramic fiber. The heating wire 7 has a spiral design and its two ends are electrically connected to the controller 4. The spiral heating wire 7 can evenly heat the inner wall of the heating tank 3, thereby conducting high-temperature testing on the internal crucible. Afterwards, the crucible is removed and the surface is observed for cracks to complete the stability test of the crucible at high temperature. The insulation layer 6 can reduce heat loss, thereby reducing energy waste.
[0024] A motor 8 is fixedly installed below the hollow plate 5. The output shaft of the motor 8 is connected to a threaded screw 9. A movable plate 10 is threadedly installed on the threaded screw 9. A limit groove 17 is opened on the movable plate 10. A limit block 16 slides in the limit groove 17. When the movable plate 10 moves, the limit block 16 will slide in the limit groove 17. Eventually, the limit block 16 will contact one end of the limit groove 17, thereby restricting the movement of the movable plate 10 and preventing the movable plate 10 from detaching from the hollow plate 5.
[0025] A sealing end cap 11 is connected to the movable plate 10, and a connecting plate 12 is connected below the sealing end cap 11. Multiple partitions 13 are connected inside the connecting plate 12. An adjusting screw 14 is threaded onto the partition 13, and contact blocks 15 are connected to both ends of the adjusting screw 14. There are three partitions 13 in total, which divide the connecting plate 12 into three areas at equal intervals. The contact blocks 15 are provided with anti-slip textures. The multiple partitions 13 allow the operator to place multiple crucibles at the same time for high-temperature resistance testing, improving testing efficiency. The anti-slip textures on the contact blocks 15 increase the contact friction with the crucibles, thereby preventing the crucibles from sliding.
[0026] The working principle of this utility model is as follows:
[0027] The staff inverts the crucible to be tested onto the partition 13, then turns the adjusting screw 14 by turning the contact block 15 at one end, causing the contact block 15 at the other end to contact the inner wall of the crucible, thus positioning the crucible. Alternatively, by turning both adjusting screws 14, both contact blocks 15 simultaneously contact the outer and inner walls of the crucible, thus clamping and fixing the crucible to prevent it from sliding. Then, the motor 8 is started to drive the threaded screw 9 to rotate, causing the movable plate 10 to slide into the hollow plate 5. This causes the movable plate 10 to pull the sealing end cover 11 down, causing the connecting plate 12 to enter the heating tank 3, thus pushing the crucible into the heating tank 3 to complete the feeding. The inner wall of the heating tank 3 is heated by the heating wire 7, so that the crucible is in a high-temperature environment. Finally, the crucible is taken out and its surface is observed, thus completing the high-temperature resistance test of the crucible.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
