Description

Technical Field

[0001] This utility model belongs to the field of vacuum sintering furnace technology, and specifically relates to a temperature measuring device and a vacuum sintering furnace. Background Technology

[0002] A vacuum sintering furnace is a key piece of equipment for high-temperature heat treatment of materials in a vacuum or low-pressure environment. It is especially suitable for the precision sintering and heat treatment processes of metals and their alloys. Its core function is to effectively improve the density, mechanical properties and microstructure uniformity of materials by eliminating oxidation interference and gaseous impurities. During this process, it is necessary to use a precision temperature measuring device to monitor the temperature field distribution inside the furnace in real time to ensure the precise control of process parameters and the consistency of product quality.

[0003] As a core component for real-time monitoring of temperature distribution in vacuum sintering furnaces, temperature measuring devices can accurately reflect the thermal field status inside the furnace to support process control. However, traditional temperature measuring devices are prone to performance degradation, calibration drift, or even structural failure due to long-term exposure to high-temperature radiation and conduction environments, which significantly shortens their service life, thereby affecting temperature control accuracy and process stability, and increasing equipment maintenance costs. Utility Model Content

[0004] In view of the problem that temperature measuring devices are prone to performance degradation, calibration drift and even structural failure due to long-term exposure to high temperature radiation and conduction environment, this utility model proposes a temperature measuring device and a vacuum sintering furnace to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a temperature measuring device installed on a furnace body, including a connecting and storing assembly. The connecting and storing assembly has a flipping assembly inside. The flipping end of the flipping assembly has two sets of monitoring components symmetrically arranged on the top and bottom. The top of the connecting and storing assembly has a heat dissipation shielding assembly. A sealing assembly is provided between the connecting and storing assembly and the flipping end.

[0007] The flipping component is used to flip the two sets of monitoring components to adjust their positions. The sealing component cooperates with the flipping component to divide the connecting and storing component into upper and lower parts so that the shielding and heat dissipation component can dissipate heat to the monitoring component on the upper side of the flipping component.

[0008] Furthermore, the connecting storage component includes a through groove, and multiple through grooves are provided on the outer surface of the furnace body. Several storage frames are fixedly connected to the outer surface of the furnace body corresponding to the through grooves.

[0009] Furthermore, the flipping assembly includes a rotating groove, which is formed inside the storage frame. A rotating shaft is rotatably connected inside the rotating groove, and several flipping plates are fixedly connected to the outer surface of the rotating shaft. A motor is provided outside the storage frame, and the output end of the motor is fixedly connected to the rotating shaft.

[0010] Furthermore, the monitoring component includes a mounting plate, which is fixedly connected between two adjacent flip plates. Two mounting plates are arranged vertically around a pivot axis, and several temperature sensors are fixedly connected to the top of the flip plates.

[0011] Furthermore, the heat dissipation shielding assembly includes a plug slot, which is located on the top of the storage frame. A plug frame is inserted into the plug slot, and a shielding plate is fixedly connected to the top of the plug frame. The shielding plate is fixedly installed on the top of the storage frame, and a plurality of heat dissipation slots are provided on the top of the shielding plate.

[0012] Furthermore, the sealing assembly includes a sealing groove, which is formed on one side of the flip plate and extends through the storage frame. A shielding groove is formed on the outer side of the storage frame corresponding to the sealing groove. A T-shaped strip is movably connected inside the shielding groove, and a sealing plate is fixedly connected to the inner side of the T-shaped strip. The sealing plate is movably connected to the sealing groove.

[0013] Furthermore, several mounting brackets are fixedly connected to the outer side of the storage frame, and a hydraulic cylinder is fixedly installed on the top of one of the mounting brackets. The output end of the hydraulic cylinder passes through the mounting bracket and is fixedly connected to the T-shaped strip. A guide rod is fixedly connected to the outer side of the T-shaped strip, and the guide rod is movably connected to the corresponding mounting bracket.

[0014] A vacuum sintering furnace includes a furnace body, a support rod fixedly connected to the inner wall of the furnace body, a support frame fixedly connected to the top of the support rod, a support groove formed on the inner wall of the support frame, a support bar movably connected inside the support groove, a placement frame fixedly connected to one side of the support bar, a plurality of placement rods fixedly connected to the inner wall of the placement frame, a support frame fixedly connected to the outer side of the furnace body, and a motor fixedly mounted on the support frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model enables the periodic exchange of positions between two sets of monitoring components within the connecting and storage component by driving the flipping component. The monitoring component in the working position continuously performs temperature monitoring tasks, while the monitoring component switched to the non-working position is cooled by the heat dissipation component. This dynamic switching mechanism effectively prevents the accumulation of thermal stress in the monitoring components under high temperature environment through intermittent cooling design. It avoids sensitivity attenuation or calibration drift caused by long-term exposure to high temperature radiation and conduction environment, and maintains the continuity of temperature monitoring process. Thus, it improves the service life of the device while ensuring the accuracy and stability of temperature data throughout the entire cycle.

[0017] 2. This utility model uses a hydraulic cylinder to push the T-shaped strip, allowing it to move into the interior of the shielding groove. Simultaneously, the sealing plate moves directly into the sealing groove on the flip plate under the push of the T-shaped strip. At this point, the sealing plate and the sealing groove cooperate to seal the position where the flip plate contacts the inner wall of the storage frame, thereby effectively blocking the heat conduction path of the high-temperature airflow in the furnace along the gap between the flip plate and the inner wall of the storage frame. This also ensures the cooling effect of the temperature sensor at this position.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-7 As shown, this utility model is a temperature measuring device installed on the furnace body 1, including a connecting and storing component 2. The connecting and storing component 2 is provided with a flipping component 3 inside. Two sets of monitoring components 4 are symmetrically arranged on the flipping end of the flipping component 3. A heat dissipation shielding component 5 is provided on the top of the connecting and storing component 2. A sealing component 6 is provided between the connecting and storing component 2 and the flipping end.

[0032] The flipping component 3 is used to flip the two sets of monitoring components 4 so that the positions of the two sets of monitoring components 4 can be adjusted. The sealing component 6 cooperates with the flipping component 3 to divide the connecting storage component 2 into upper and lower parts so that the shielding heat dissipation component 5 can dissipate heat to the monitoring component 4 on the upper side of the flipping component 3.

[0033] One set of monitoring components 4 monitors the temperature inside the furnace body 1 through the connection end of the storage component 2. After the monitoring component 4 has been working for a certain period of time, the flipping component 3 is flipped, so that the two sets of monitoring components 4 on the flipping component 3 exchange positions inside the storage component 2. At this time, the monitoring component 4 that has just finished its work dissipates heat with the help of the shielding heat dissipation component 5, and then the above process is repeated periodically.

[0034] By driving the flipping component 3, the two sets of monitoring components 4 can periodically switch positions within the connecting and storage component 2. The monitoring component 4 in the working position continuously performs temperature monitoring tasks, while the monitoring component 4 switched to the non-working position is cooled by the heat dissipation component 5. This dynamic switching mechanism effectively prevents the accumulation of thermal stress in the monitoring component 4 under high temperature environment through intermittent cooling design. It avoids sensitivity decay or calibration drift caused by long-term exposure to high temperature radiation and conduction environment, and maintains the continuity of temperature monitoring process. Thus, it can improve the service life of the device while ensuring the accuracy and stability of temperature data throughout the entire cycle.

[0035] In one embodiment, the connection and storage component 2 includes a through groove 201, a plurality of through grooves 201 are provided on the outer surface of the furnace body 1, and a plurality of storage frames 202 are fixedly connected to the outer surface of the furnace body 1 corresponding to the through grooves 201.

[0036] The monitoring component 4 installed inside the storage frame 202 can monitor the problems inside the furnace body 1 through the through groove 201. Since there are several storage frames 202 on the outer surface of the furnace body 1, and each storage frame 202 is equipped with a monitoring component 4, the cooperation of several monitoring components 4 can comprehensively monitor the stability inside the furnace body 1.

[0037] In one embodiment, the flipping component 3 includes a rotating groove 301, which is formed inside the storage frame 202. A rotating shaft 302 is rotatably connected inside the rotating groove 301. A plurality of flipping plates 303 are fixedly connected to the outer surface of the rotating shaft 302. A motor 304 is provided outside the storage frame 202, and the output end of the motor 304 is fixedly connected to the rotating shaft 302.

[0038] By driving the rotating shaft 302 with the motor 304, the rotating shaft 302 can drive several flip plates 303 to rotate inside the rotating groove 301. During this process, the flip plates 303 and the rotating groove 301 can always divide the storage frame 202 into upper and lower parts. The two sets of monitoring components 4 can be located in the two areas of the storage frame 202 respectively, and the two sets of monitoring components 4 will not interfere with each other when performing temperature monitoring and heat dissipation. In specific implementation, the flip plates 303 can be made of heat-insulating material, so that when one set of monitoring components 4 is dissipated, the temperature inside the furnace body 1 will not affect it.

[0039] In one embodiment, the monitoring component 4 includes a mounting plate 401, which is fixedly connected between two adjacent flip plates 303. Two mounting plates 401 are arranged vertically around a rotating shaft 302. Several temperature sensors 402 are fixedly connected to the top of the flip plates 303.

[0040] The rotating shaft 302 rotates the flip plate 303, which in turn drives the mounting plate 401 to rotate inside the rotating groove 301. When the rotating shaft 302 rotates 180°, the two mounting plates 401 are equipped with several temperature sensors 402 that can be swapped.

[0041] In one embodiment, the heat dissipation shielding assembly 5 includes a plug slot 501, which is located on the top of the storage frame 202. A plug frame 502 is inserted into the plug slot 501, and a shielding plate 503 is fixedly connected to the top of the plug frame 502. The shielding plate 503 is fixedly installed on the top of the storage frame 202, and a plurality of heat dissipation slots 504 are provided on the top of the shielding plate 503.

[0042] By moving the insertion frame 502 into the insertion slot 501, the shield 503 comes into contact with the top of the storage frame 202. Then, the shield 503 is installed on the top of the storage frame 202 by fixing bolts. This arrangement makes it more convenient to inspect and maintain the temperature sensor 402 installed inside the storage frame 202. At the same time, when several temperature sensors 402 are rotated between the flip plate 303 and the shield 503, external air can flow between the flip plate 303 and the shield 503 through the heat dissipation slot 504. At this time, several temperature sensors 402 at this position can be cooled by the airflow.

[0043] In one embodiment, the sealing assembly 6 includes a sealing groove 601, which is formed on one side of the flip plate 303 and extends through the storage frame 202. A shielding groove 602 is formed on the outer side of the storage frame 202 corresponding to the sealing groove 601. A T-shaped strip 603 is movably connected inside the shielding groove 602, and a sealing plate 604 is fixedly connected to the inner side of the T-shaped strip 603. The sealing plate 604 is movably connected to the sealing groove 601.

[0044] After the positions of several temperature sensors 402 on the two mounting plates 401 are swapped, the T-shaped strip 603 is pushed so that it can move into the interior of the shielding groove 602. At the same time, the sealing plate 604 moves directly into the sealing groove 601 opened on the flip plate 303 under the push of the T-shaped strip 603. At this time, the sealing plate 604 and the sealing groove 601 cooperate to seal the position where the flip plate 303 contacts the inner wall of the storage frame 202, so that the temperature inside the furnace body 1 is not easy to flow to the upper side of the flip plate 303, and the cooling effect of the temperature sensor 402 at this position can be guaranteed.

[0045] In one embodiment, for the storage frame 202 described above, a plurality of mounting brackets 605 are fixedly connected to the outside of the storage frame 202, and a hydraulic cylinder 606 is fixedly mounted on the top of one of the mounting brackets 605. The output end of the hydraulic cylinder 606 passes through the mounting bracket 605 and is fixedly connected to a T-shaped strip 603. A guide rod 607 is fixedly connected to the outside of the T-shaped strip 603, and the guide rod 607 is movably connected to the corresponding mounting bracket 605.

[0046] The T-shaped strip 603 is pushed by the hydraulic cylinder 606, so that the T-shaped strip 603 can drive the sealing plate 604 to move automatically into the sealing groove 601. During this operation, the guide rod 607 can slide on the corresponding mounting bracket 605 under the drive of the T-shaped strip 603. This setting ensures the stability of the T-shaped strip 603 when it moves.

[0047] Please see Figures 1-2 As shown, this utility model is a vacuum sintering furnace, including a furnace body 1. A support rod 7 is fixedly connected to the inner wall of the furnace body 1. A support frame 8 is fixedly connected to the top of the support rod 7. A support groove 9 is opened on the inner wall of the support frame 8. A support bar 10 is movably connected inside the support groove 9. A placement frame 11 is fixedly connected to one side of the support bar 10. A plurality of placement rods 12 are fixedly connected to the inner wall of the placement frame 11. A support frame 13 is fixedly connected to the outer side of the furnace body 1. The motor 304 is fixedly installed on the support frame 13.

[0048] By pulling the placement frame 11, the placement frame 11 moves the support bar 10 inside the support groove 9, allowing the placement frame 11 to move out of the furnace body 1. Then, the material is placed inside the placement rod 12 outside the furnace body 1. After placement, the placement frame 11 is pushed again, allowing the material to move into the furnace body 1. At this time, supported by the support frame 8, the placement frame 11, and the placement rod 12, the material can be almost suspended inside the furnace body 1. The above setup enables rapid loading and unloading of materials through the retractable placement frame 11. At the same time, the suspended material in the placement frame 11 and placement rod 12 ensures a more uniform temperature distribution on the surface of the material during heat treatment.

[0049] Through the above technical solution, 1. By driving the flipping component 3, the two sets of monitoring components 4 can periodically switch positions within the connecting and storing component 2. The monitoring component 4 in the working position continuously performs temperature monitoring tasks, while the monitoring component 4 switched to the non-working position is cooled by the heat dissipation component 5. This dynamic switching mechanism effectively prevents the accumulation of thermal stress in the monitoring component 4 under high-temperature environments through intermittent cooling design. This avoids sensitivity attenuation or calibration drift caused by long-term exposure to high-temperature radiation and conduction environments, and maintains the continuity of the temperature monitoring process. Thus, it extends the service life of the device while ensuring temperature stability throughout the entire cycle. 1. Accuracy and stability of data; 2. The T-shaped bar 603 is pushed by the hydraulic cylinder 606, so that the T-shaped bar 603 can move into the interior of the shielding groove 602. At the same time, the sealing plate 604 moves directly into the sealing groove 601 opened on the flip plate 303 under the push of the T-shaped bar 603. At this time, the sealing plate 604 and the sealing groove 601 cooperate to seal the position where the flip plate 303 contacts the inner wall of the storage frame 202, thereby effectively blocking the heat conduction path of the high temperature airflow in the furnace body 1 along the gap between the flip plate 303 and the inner wall of the storage frame 202. At the same time, the cooling effect of the temperature sensor 402 at this position can be guaranteed.
