Description

Technical Field

[0001] This utility model relates to the field of vacuum degassing furnaces, specifically a leak-proof sealing device for vacuum degassing furnaces. Background Technology

[0002] A vacuum degassing furnace is an industrial device that uses a vacuum environment to remove gases from materials. It is mainly used in metallurgy, materials processing, and other fields. Its core principle is to reduce the partial pressure of gases through vacuum, causing dissolved or free gases to precipitate from the material. Argon gas drives the molten steel to circulate, forming droplets in the vacuum chamber to expand the degassing area. This effectively removes gases such as hydrogen and oxygen, and the processing capacity typically exceeds 30 tons.

[0003] A leak-proof vacuum degassing furnace, as disclosed in Chinese Patent No. CN221964545U, includes a furnace body and a sealing cover. A hinged column is installed on one side of the furnace body, and a connecting block is installed on one side of the top of the sealing cover. The bottom end of the connecting block is connected to the hinged column via a hinge key. A second mounting platform is installed on one side of the furnace body. A motor is installed on the top of the sealing cover, and a drive shaft is installed at the bottom of the sealing cover. A defoaming turntable is installed at the bottom of the drive shaft, and multiple defoaming nets are installed on the top of the defoaming turntable. This invention utilizes the rotation of the defoaming turntable to force the liquid inside the turntable out through centrifugal force. Furthermore, the defoaming nets disperse the air bubbles in the liquid, allowing the gas contained within the bubbles to leak out. This device improves the thorough removal of gas from the liquid, thereby enhancing product quality.

[0004] Existing leak-proof sealing devices for vacuum degassing furnaces require the gas separated inside the furnace to be discharged through a metal exhaust pipe during use. However, this causes dust to enter the furnace body through the pipe when the furnace is not in use, increasing the maintenance cost of the furnace. Therefore, a leak-proof sealing device for vacuum degassing furnaces is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a leak-proof sealing device for a vacuum degassing furnace.

[0007] Preferably, a snap-fit ​​body is fixedly connected to the top of the outer furnace of the degassing furnace, and a rotating shaft is rotatably connected to the inner surface of the snap-fit ​​body, with a knob fixedly connected to one end of the rotating shaft.

[0008] Preferably, one end of the rotating shaft is fixedly connected to a threaded rod, and the outer wall of the threaded rod is threadedly connected to a snap-fit ​​block, which is slidably connected to the inner wall of the snap-fit ​​body.

[0009] Preferably, the top of the outer furnace of the degassing furnace is fixedly connected with an internal threaded ring, and the inner surface of the internal threaded ring is threadedly connected with an external threaded ring.

[0010] Preferably, a cap is fixedly connected to the top of the external threaded ring, and a heat-resistant funnel is fixedly connected to the top of the cap.

[0011] Preferably, a metal support frame is fixedly connected to the outer wall of the degassing furnace outer furnace, and a transparent glass plate is fixedly connected to one side of the degassing furnace outer furnace.

[0012] Preferably, a hemispherical valve body is installed at the bottom of the outer furnace of the degassing furnace, and the top of the hemispherical valve body is connected to the inner furnace of the degassing furnace.

[0013] The advantages of this utility model are:

[0014] This invention, by setting a rubber piston plate that can slide inside the piston tube, allows the degassing furnace to exhaust freely, thus assisting in the degassing furnace's exhaust function. It also prevents leakage when the degassing furnace is not in use, solving the problem that dust can easily enter the furnace body along the metal exhaust pipe when the degassing furnace is not in use.

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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a leak-proof sealing device for a vacuum degassing furnace. (Refer to...) Figure 3 and Figure 5The system includes an outer furnace 1 for the degassing furnace, a metal exhaust pipe 7 connected to one side of the outer furnace 1, a leak-proof body 8 connected to the top of the metal exhaust pipe 7, an exhaust groove 9 on the outer wall of the leak-proof body 8, a telescopic rod 23 fixedly connected to the inner top wall of the leak-proof body 8, a fixing plate 19 fixedly connected to the bottom of the telescopic rod 23, a rubber piston plate 18 fixedly connected to the bottom of the fixing plate 19, a spring 24 fixedly connected to the fixing plate 19 via the leak-proof body 8, a piston tube 25 fixedly connected to the inner surface wall of the leak-proof body 8, an electric push rod 22 installed on the inner top wall of the leak-proof body 8, an inner sliding rod 20 fixedly connected to the output end of the electric push rod 22 through the fixing plate 19, and a rubber piston block 21 fixedly connected to the outer wall of the inner sliding rod 20. The system, via the metal exhaust pipe 7, allows the gas inside the outer furnace 1 to escape through the exhaust pipe. The gas can enter the interior of the leak-proof body 8 through the metal exhaust pipe 7. When the gas accumulates on one side of the rubber piston plate 18, the gas pressure on one side of the rubber piston plate 18 will rise. At this time, the rubber piston plate 18 will slide inside the piston tube 25. The telescopic rod 23 and the spring 24 will be compressed simultaneously. The fixed plate 19 will slide synchronously on the outer wall of the inner slide rod 20 until the rubber piston plate 18 is separated from the piston tube 25. Then the gas can be discharged along the exhaust groove 9. When it is necessary to actively connect the exhaust, the electric push rod 22 can be activated to raise the inner slide rod 20 and the rubber piston block 21, so that the rubber piston plate 18 will rise actively. When the degassing furnace is not in use, the compressed spring 24 will push the rubber piston plate 18 into the interior of the piston tube 25 for sealing.

[0026] Reference Figure 3 and Figure 4 The top of the outer furnace 1 of the degassing furnace is fixedly connected to a snap-fit ​​body 4. The inner surface of the snap-fit ​​body 4 is rotatably connected to a rotating shaft 15. One end of the rotating shaft 15 is fixedly connected to a knob 14. The knob 14 is set so that the rotating shaft 15 can be driven to rotate inside the snap-fit ​​body 4 after being manually rotated.

[0027] Reference Figure 3 and Figure 4 One end of the rotating shaft 15 is fixedly connected to a threaded rod 16, and a snap-fit ​​block 17 is threadedly connected to the outer wall of the threaded rod 16. The snap-fit ​​block 17 is slidably connected to the inner wall of the snap-fit ​​body 4. By setting the threaded rod 16, the rotating shaft 15 can rotate the threaded rod 16 synchronously, thereby causing the threaded rod 16 to drive the snap-fit ​​block 17 to slide and limit its movement on the inner wall of the snap-fit ​​body 4.

[0028] Reference Figure 3 and Figure 4 An internal threaded ring 10 is fixedly connected to the top of the outer furnace 1 of the degassing furnace. An external threaded ring 13 is threadedly connected to the inner surface of the internal threaded ring 10. The internal threaded ring 10 is configured so that the external threaded ring 13 can be threadedly connected inside the internal threaded ring 10.

[0029] Reference Figure 3 and Figure 4 The top of the external threaded ring 13 is fixedly connected to a cap 6, and the top of the cap 6 is fixedly connected to a heat-resistant funnel 5. The cap 6 is designed so that the rotation of the cap 6 can rotate the external threaded ring 13 to disengage from and connect to the internal threaded ring 10. The snap-fit ​​block 17 can be snapped onto one side of the cap 6 for fixation. At the same time, the heat-resistant funnel 5 can assist in feeding.

[0030] Reference Figure 2 and Figure 3 A metal support frame 2 is fixedly connected to the outer wall of the degassing furnace 1, and a transparent glass plate 3 is fixedly connected to one side of the degassing furnace 1. The transparent glass plate 3 allows the user to better observe the interior of the degassing furnace 1.

[0031] Reference Figure 2 and Figure 3 A hemispherical valve body 11 is installed at the bottom of the outer furnace 1 of the degassing furnace. The top of the hemispherical valve body 11 is connected to the inner furnace 12 of the degassing furnace. The hemispherical valve body 11 can freely control the entry and exit of materials.

[0032] Working principle: The metal exhaust pipe 7 allows gas from the outer furnace 1 of the degassing furnace to enter the leak-proof body 8. When gas accumulates on one side of the rubber piston plate 18, the gas pressure on that side rises, causing the rubber piston plate 18 to slide inside the piston tube 25. Simultaneously, the telescopic rod 23 and spring 24 are compressed, and the fixing plate 19 slides synchronously on the outer wall of the inner sliding rod 20 until the rubber piston plate 18 disengages from the piston tube 25, allowing the gas to exit through the exhaust groove 9. When active exhaust is required, the electric actuator 22 can be activated to raise the inner sliding rod 20 and the rubber piston block 21, causing the rubber piston plate 18 to rise actively. When the degassing furnace is not in use, the compressed spring 24 pushes the rubber piston plate 18 into the piston tube 25 for sealing. The knob 14 is designed so that when manually rotated, it drives the rotating shaft 15 to rotate inside the clamping body 4. The threaded rod 16 is designed so that when the rotating shaft 15 rotates, the threaded rod 16 rotates synchronously, thereby causing the threaded rod 16 to drive the clamping block 17 to slide within the inner surface of the clamping body 4. The inner threaded ring 10 is designed so that the outer threaded ring 13 can be threadedly connected inside the inner threaded ring 10. The cap 6 is designed so that the rotation of the cap 6 can rotate the outer threaded ring 13 to disengage from and connect to the inner threaded ring 10. The clamping block 17 can be clamped and fixed on one side of the cap 6. The heat-resistant funnel 5 is designed to assist in feeding. The transparent glass plate 3 is designed so that the user can better observe the inside of the outer furnace 1 of the degassing furnace. The hemispherical valve body 11 is designed so that the material can be freely controlled to enter and exit.
