Description

Technical Field

[0001] This utility model relates to the field of high-temperature sintering furnace technology, specifically a micro-sodium corundum sintering furnace with temperature control function. Background Technology

[0002] A sintering furnace is a specialized device that enables powder compacts to obtain the required physical and mechanical properties and microstructure through sintering. Common sintering furnaces with temperature control functions generally use corundum tubes as heating elements. Corundum tubes have good thermal conductivity, which can provide a uniform heating effect and ensure the uniformity and stability of temperature in various parts of the sample. Corundum tubes are a high-temperature refractory material that is stable in operation and not easily deformed or damaged.

[0003] Common tubular sintering furnaces are usually separate furnace bodies and furnace tubes. When installing a tubular sintering furnace, the corundum tubes are usually installed into the installation cavity of the sintering furnace. Because common sintering furnace tubes do not have limit devices, it is not easy for workers to install the furnace tubes in the middle position. Moreover, after installation, gaps may appear between the furnace tubes and the sides of the furnace body after long-term use, which may cause uneven heating and thus affect the heating effect of the samples inside the furnace tubes.

[0004] Therefore, we propose a micro-sodium corundum sintering furnace with temperature control function. Utility Model Content

[0005] The purpose of this invention is to provide a micro-sodium corundum sintering furnace with temperature control function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a micro-sodium corundum sintering furnace with temperature control function, comprising a sintering furnace body, an corundum tube body installed inside the sintering furnace body, a limiting component, the limiting component being installed on the left side of the outer surface of the sintering furnace body, the limiting component facilitating the worker's judgment of the installation position when installing the corundum tube body, the limiting component being used to seal the gap between the left side of the sintering furnace body and the corundum tube body, and a sealing component, the sealing component being installed on the right side of the sintering furnace body, the sealing component being used to assist the limiting component in sealing the left side of the sintering furnace body, and the sealing component being used to seal the gap between the right side of the sintering furnace body and the corundum tube body.

[0007] Preferably, the limiting assembly includes a first left-side sealing ring, a second left-side sealing ring rotatably connected to the rear of the bottom surface of the first left-side sealing ring, a hinge block rotatably connected to the front of the bottom surface of the first left-side sealing ring, two limiting grooves formed on the left side of the hinge block, two limiting rods snapped into the front of the left side of the second left-side sealing ring, the size of each limiting rod being adapted to the size of its corresponding limiting groove, a fixing plate fixedly connected to the left side of the two limiting rods, and a small elastic steel plate fixedly installed between the fixing plate and the second left-side sealing ring.

[0008] Preferably, after the first and second left-side sealing rings are closed, the diameter of their inner walls is adapted to the outer diameter of the corundum tube body.

[0009] Preferably, the sealing assembly includes a first right-side sealing ring, which is fixedly connected to the flip-top cover on the right side of the sintering furnace body. A fixing block is fixedly connected to the rear of the upper surface of the second right-side sealing ring. A limiting block is rotatably connected to the upper surface of the fixing block. Both the fixing block and the limiting block are engaged with the first right-side sealing ring. A threaded rod is rotatably connected to the rear of the bottom surface of the second right-side sealing ring. The threaded rod is threadedly connected to the first right-side sealing ring.

[0010] Preferably, the inner diameter of the first right-side sealing ring and the second right-side sealing ring after closure is adapted to the outer diameter of the corundum tube body.

[0011] Preferably, a mounting bracket is fixedly connected to the lower part of the outer surface of the second right-side sealing ring, a large elastic steel plate is fixedly connected to the right side of the mounting bracket, and a pusher is fixedly connected to the other end of the large elastic steel plate.

[0012] Preferably, the size of the groove in the pusher is adapted to the outer diameter of the corundum tube body.

[0013] Preferably, the pusher is made of a non-slip material.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. When installing a new corundum tube body, first install the limiting assembly to a suitable position on the outer surface of the corundum tube body. First, flip the first and second left-side sealing rings open so that they fit on the left side of the outer surface of the corundum tube body. Do not lock the first and second left-side sealing rings at this time. Adjust the position of the first and second left-side sealing rings on the surface of the corundum tube body. After the position is adjusted, pull the fixing plate to pull out the limiting rod partly. Then, flip the hinge block inside the second left-side sealing ring and insert the limiting rod into the limiting groove. The small elastic steel plate can be used to ensure that after the tension on the fixing plate is released, the elasticity of the small elastic steel plate will allow the limiting rod to be inserted into the limiting groove without the limiting rod accidentally falling out of the limiting groove. This will securely lock the first and second left-side sealing rings to the surface of the corundum tube body.

[0016] By setting a limiting component, after the first and second left-side sealing rings are installed, the installation position of the corundum tube body can be determined by judging the positions of the first and second left-side sealing rings.

[0017] 2. After the limiting component is installed, the corundum tube body is placed inside the sintering furnace. First, the limiting block and fixing block are passed through the opening of the first right-side sealing ring. At this point, the threaded rod of the second right-side sealing ring will contact the first right-side sealing ring. Through the threaded connection between the threaded rod and the first right-side sealing ring, the threaded rod can be screwed into the first right-side sealing ring. Then, the second right-side sealing ring is moved closer to the first right-side sealing ring. The limiting block will then completely pass through the first right-side sealing ring. Next, the limiting block is rotated 90 degrees clockwise to firmly fix the position of the second right-side sealing ring. While the second right-side sealing ring is being installed, the pusher will contact the right side of the outer surface of the corundum tube body. As the second right-side sealing ring continues to rise, the pusher, under the elastic force of the high-elasticity steel plate, will apply a rightward pushing force to the entire corundum tube body. This achieves the effect of the limiting component firmly contacting the left side of the sintering furnace body, thereby sealing the gaps after the sintering furnace body is closed.

[0018] By setting up a sealing component, the gaps on the left and right sides of the sintering furnace body can be sealed when the corundum tube body is installed inside the sintering furnace body, which further allows the part of the corundum tube body inside the sintering furnace body to be heated more evenly.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 This utility model provides a technical solution:

[0028] Example 1: A micro-sodium corundum sintering furnace with temperature control function includes a sintering furnace body 3, a corundum tube body 4 installed inside the sintering furnace body 3, a limiting component 1 installed on the left side of the outer surface of the sintering furnace body 3, the limiting component 1 facilitating the operator to determine the installation position when installing the corundum tube body 4, the limiting component 1 being used to seal the gap between the left side of the sintering furnace body 3 and the corundum tube body 4, and a sealing component 2 installed on the right side of the sintering furnace body 3, the sealing component 2 assisting the limiting component 1 in sealing the left side of the sintering furnace body 3, and the sealing component 2 being used to seal the gap between the right side of the sintering furnace body 3 and the corundum tube body 4.

[0029] The limiting component 1 includes a first left-side sealing ring 5, a second left-side sealing ring 6 rotatably connected to the rear of the bottom surface of the first left-side sealing ring 5, a hinge block 7 rotatably connected to the front of the bottom surface of the first left-side sealing ring 5, two limiting grooves 8 are formed on the left side of the hinge block 7, and two limiting rods 9 are snapped into the front of the left side of the second left-side sealing ring 6. The size of each limiting rod 9 is adapted to the size of its corresponding limiting groove 8. A fixing plate 10 is fixedly connected to the left side of the two limiting rods 9, and a small elastic steel plate 11 is fixedly installed between the fixing plate 10 and the second left-side sealing ring 6.

[0030] After the first left-side sealing ring 5 and the second left-side sealing ring 6 are closed, the diameter of their inner walls is matched with the outer diameter of the corundum tube body 4.

[0031] When installing the new corundum tube body 4, firstly, install the limiting component 1 to a suitable position on the outer surface of the corundum tube body 4. Then, flip the first left-side sealing ring 5 and the second left-side sealing ring 6 so that they fit onto the left side of the outer surface of the corundum tube body 4. Do not lock the first left-side sealing ring 5 and the second left-side sealing ring 6 immediately. Adjust the positions of the first left-side sealing ring 5 and the second left-side sealing ring 6 on the surface of the corundum tube body 4. After the position adjustment is complete, pull the fixing plate 10 to achieve the desired effect. The limiting rod 9 is pulled out partially. At this time, the hinge block 7 is flipped into the second left sealing ring 6, and then the limiting rod 9 is inserted into the limiting groove 8. Through the small elastic steel plate 11, the tension on the fixing plate 10 is released, and the elasticity of the small elastic steel plate 11 will allow the limiting rod 9 to be inserted into the limiting groove 8. The limiting rod 9 will not accidentally fall out of the limiting groove 8. At this time, the first left sealing ring 5 and the second left sealing ring 6 can be firmly locked on the surface of the corundum tube body 4.

[0032] By setting the limiting component 1, after the first left-side sealing ring 5 and the second left-side sealing ring 6 are installed, the installation position of the corundum tube body 4 can be determined by judging the position of the first left-side sealing ring 5 and the second left-side sealing ring 6.

[0033] In embodiment 2, the sealing component 2 includes a first right-side sealing ring 12, which is fixedly connected to the flip cover on the right side of the sintering furnace body 3. A fixing block 14 is fixedly connected to the rear of the upper surface of the second right-side sealing ring 13. A limiting block 15 is rotatably connected to the upper surface of the fixing block 14. Both the fixing block 14 and the limiting block 15 are engaged with the first right-side sealing ring 12. A threaded rod 19 is rotatably connected to the rear of the bottom surface of the second right-side sealing ring 13. The threaded rod 19 is threadedly connected to the first right-side sealing ring 12.

[0034] The inner diameter of the first right-side sealing ring 12 and the second right-side sealing ring 13 after they are closed is adapted to the outer diameter of the corundum tube body 4.

[0035] A mounting bracket 16 is fixedly connected to the lower part of the outer surface of the second right-side sealing ring 13. A large elastic steel plate 17 is fixedly connected to the right side of the mounting bracket 16. A pusher 18 is fixedly connected to the other end of the large elastic steel plate 17.

[0036] The size of the groove in the pusher 18 is matched with the outer diameter of the corundum tube body 4.

[0037] The pusher 18 is made of non-slip material.

[0038] After the limiting component 1 is installed, the corundum tube body 4 is placed inside the sintering furnace body 3. Then, the limiting block 15 and the fixing block 14 are passed through the opening of the first right-side sealing ring 12. At this point, the threaded rod 19 of the second right-side sealing ring 13 will contact the first right-side sealing ring 12. Through the threaded connection between the threaded rod 19 and the first right-side sealing ring 12, the threaded rod 19 can be screwed into the first right-side sealing ring 12. Then, the second right-side sealing ring 13 is moved closer to the first right-side sealing ring 12. At this point, the limiting block 15 will completely pass through the first right-side sealing ring 12. Rotating the limiting block 15 clockwise by 90 degrees will securely fix the position of the second right-side sealing ring 13. When the second right-side sealing ring 13 is installed, the pusher 18 will contact the right side of the outer surface of the corundum tube body 4. As the second right-side sealing ring 13 continues to rise, the pusher 18 will apply a rightward pushing force to the corundum tube body 4 under the action of the elasticity of the high-elasticity steel plate 17. At this time, the limiting component 1 will be firmly in contact with the left side of the sintering furnace body 3, thereby achieving the purpose of sealing the gap after the sintering furnace body 3 is closed.

[0039] By setting the sealing component 2, the gaps on the left and right sides of the sintering furnace body 3 can be sealed when the corundum tube body 4 is installed inside the sintering furnace body 3, which further allows the part of the corundum tube body 4 inside the sintering furnace body 3 to be heated more evenly.
