Description

Technical Field

[0001] This utility model relates to the technical field of nitrogen-protected annealing tanks, specifically a sealing structure for a nitrogen-protected annealing tank. Background Technology

[0002] Annealing is a crucial step in cable manufacturing, aiming to improve the mechanical properties and microstructure of metal wires through heating and cooling processes. During annealing, the wire coil is typically placed in a sealed annealing chamber filled with a protective medium such as nitrogen to prevent surface oxidation caused by contact with oxygen at high temperatures, thus ensuring the quality and performance of the wire.

[0003] In existing technologies, annealing tanks mostly adopt a split structure design, mainly consisting of two parts: the tank body and an openable / closable lid. For example... Figure 6 As shown, the tank body and the cover are sealed together by a ring-shaped array of high-strength bolts. Specifically, several sets of through holes are correspondingly opened on the outer periphery of the cover and the flange of the tank body. Before loading the wire coil, the operator must sequentially insert the bolts and tighten the nuts to form a rigid connection and ensure sealing. After the annealing process, the bolts and nuts must be removed one by one to open the cover and remove the wire coil. However, this traditional bolt connection method has the following significant drawbacks in actual production:

[0004] Cable production is characterized by high-frequency, continuous operations, requiring multiple batches of annealing processes daily. This necessitates repeated disassembly and assembly of bolts and nuts. During these repeated disassembly and assembly processes, bolt and nut threads are prone to misalignment due to improper handling, leading to thread damage and increasing the scrap rate of bolts and nuts, thus raising production costs. Furthermore, the small size and large quantity of disassembled bolts and nuts make them easily lost at the work site, further increasing maintenance costs and management difficulties. Utility Model Content

[0005] The purpose of this invention is to provide a sealing structure for a nitrogen-protected annealing vessel to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The device includes a tank body; an auxiliary sealing assembly installed on the upper surface of the tank body; a first air pipe and a second air pipe fixed to the surface of the tank body and located above the auxiliary sealing assembly, with the inner cavities of the first air pipe and the second air pipe communicating with the inner cavity of the tank body; a sealing assembly installed on the top surface of the tank body; an auxiliary sealing assembly for fixing the sealing assembly to the top surface of the tank body; and a protective assembly installed on the top surface of the sealing assembly. The auxiliary sealing assembly includes a ring fixed to the upper surface of the tank body; lugs fixed at equal intervals to the top surface of the ring; a swing shaft rotatably connected to the lugs; a screw fixed to the surface of the swing shaft; a locking nut threaded to the upper surface of the screw; a pressure plate rotatably connected to the bottom surface of the locking nut; cylinders fixed at equal intervals to the surface of the locking nut; and an auxiliary swing component installed on the bottom surface of the ring.

[0008] Preferably, the auxiliary swing component includes an adjusting threaded rod, a guide rod, and a swing gear. The bottom surface of the ring is rotatably connected to the adjusting threaded rod, and a movable ring is threadedly connected to the surface of the adjusting threaded rod. The bottom surface of the ring is symmetrically and fixedly connected to the guide rod. The movable ring slides on the surfaces of the tank and the guide rod, respectively. The top surface of the movable ring is fixedly connected with a rotating rack at equal intervals. The rotating rack meshes with the swing gear. The surface of the swing shaft is fixedly connected to the swing gear.

[0009] Preferably, the sealing assembly includes a sealing cap, which is placed on the top surface of the tank. A convex circle is fixedly connected to the center of the bottom surface of the sealing cap, which is located inside the tank. The top surface of the sealing cap has a U-shaped groove array, and the screw is located in the U-shaped groove.

[0010] As a preferred embodiment, the sealing assembly also includes hooks, with the top surface of the sealing cap symmetrically and fixedly connected to the hooks.

[0011] As a preferred embodiment, the protective assembly includes a gas valve, a pressure gauge, and a protective cover. The gas valve and the pressure gauge are fixedly connected to the top surface of the sealing cover, respectively. The gas valve and the pressure gauge are respectively connected to the tank body. The protective cover is fixedly connected to the top surface of the sealing cover and outside the pressure gauge.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By tightening the locking nut, the locking nut moves on the surface of the screw. When the locking nut moves, it will drive the pressure plate closer to the sealing assembly. At this time, the sealing assembly can be fixed on the tank body to achieve the sealing of the tank body.

[0014] 2. By rotating the adjusting threaded rod, the adjusting threaded rod drives the moving ring and the rotating rack to rise and fall. As the rotating rack rises and falls, it drives the swing gear to rotate, thereby driving multiple sets of screws to rotate, so that the screws enter the U-shaped groove for easy sealing later, or disengage from the U-shaped groove for easy removal of the sealing components later.

[0015] 3. The top surface of the tank can be sealed by the sealing cap and the convex circle in the sealing assembly. At the same time, after the convex circle enters the tank, it also achieves the initial positioning of the sealing cap.

[0016] 4. The pressure gauge can monitor the pressure inside the tank in real time to determine if there is any leakage, ensuring the smooth progress of subsequent annealing.

[0017] 5. The protective cover can protect the barometer from damage by external objects, thereby reducing resource loss. Attached Figure Description

[0031] 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.

[0032] Example: This utility model provides a technical solution for the sealing structure of a nitrogen-protected annealing vessel, such as... Figures 1-5 As shown, the system includes: a tank body 100; an auxiliary sealing assembly 200 mounted on the upper surface of the tank body 100; a first air pipe 300 and a second air pipe 400 fixed to the surface of the tank body 100 and located above the auxiliary sealing assembly 200, with the inner cavities of the first air pipe 300 and the second air pipe 400 communicating with the inner cavity of the tank body 100; a sealing assembly 500 mounted on the top surface of the tank body 100; an auxiliary sealing assembly 200 for fixing the sealing assembly 500 to the top surface of the tank body 100; and a protective assembly mounted on the top surface of the sealing assembly 500. 600; The auxiliary sealing assembly 200 includes a ring 201 fixed to the upper part of the surface of the tank body 100, lugs 202 fixed at equal intervals to the top surface of the ring 201, a swing shaft 203 rotatably connected to the lugs 202, a screw 204 fixed to the surface of the swing shaft 203, a locking nut 205 threaded to the upper part of the surface of the screw 204, a pressure plate 206 rotatably connected to the bottom surface of the locking nut 205, cylinders 207 fixed at equal intervals to the surface of the locking nut 205, and an auxiliary swing component installed on the bottom surface of the ring 201.

[0033] By tightening the locking nut 205, the locking nut 205 moves on the surface of the screw 204. When the locking nut 205 moves, it will drive the pressure plate 206 to approach the sealing assembly 500. At this time, the sealing assembly 500 can be fixed on the tank 1 to achieve the sealing of the tank 1.

[0034] like Figure 4 and Figure 5As shown, the auxiliary swing component includes an adjusting threaded rod 208, a guide rod 209, and a swing gear 210. The adjusting threaded rod 208 is rotatably connected to the bottom surface of the ring 201. A moving ring 211 is threadedly connected to the surface of the adjusting threaded rod 208. The guide rod 209 is symmetrically and fixedly connected to the bottom surface of the ring 201. The moving ring 211 slides on the surfaces of the tank 100 and the guide rod 209 respectively. A rotating rack 212 is fixedly connected at equal intervals to the top surface of the moving ring 211. The rotating rack 212 meshes with the swing gear 210. The swing shaft 203 is fixedly connected to the surface of the swing gear 210.

[0035] By rotating the adjusting threaded rod 208, the adjusting threaded rod 208 drives the moving ring 211 and the rotating rack 212 to rise and fall. As the rotating rack 212 rises and falls, it drives the swing gear 210 to rotate, thereby driving multiple sets of screws 204 to rotate, so that the screws 204 enter the U-shaped groove 503 for easy sealing later, or disengage from the U-shaped groove 503 for easy removal of the sealing assembly 500 later.

[0036] like Figure 2 and Figure 3 As shown, the sealing assembly 500 includes a sealing cap 501, which is placed on the top surface of the tank 100. A convex circle 502 is fixedly connected to the center of the bottom surface of the sealing cap 501, and the convex circle 502 is located inside the tank 100. A U-shaped groove 503 is arranged circumferentially on the top surface of the sealing cap 501, and a screw 204 is located within the U-shaped groove 503. The sealing assembly 500 also includes a hook 504, which is symmetrically fixedly connected to the top surface of the sealing cap 501.

[0037] The sealing cap 501 and the convex circle 502 in the sealing assembly 500 can seal the top surface of the tank 1. At the same time, after the convex circle 502 enters the tank 1, it also achieves the initial positioning of the sealing cap 501.

[0038] like Figure 2 As shown, the protection component 600 includes a gas valve 601, a pressure gauge 602, and a protective cover 603. The gas valve 601 and the pressure gauge 602 are fixedly connected to the top surface of the sealing cover 501, respectively. The gas valve 601 and the pressure gauge 602 are respectively connected to the inside of the tank body 100. The protective cover 603 is fixedly connected to the top surface of the sealing cover 501 and outside the pressure gauge 602.

[0039] The pressure gauge 602 can monitor the pressure inside the tank 1 in real time, determine whether there is a leak in the pressure inside the tank 1, and ensure that the subsequent annealing can proceed.

[0040] The protective cover 603 can protect the barometer 602 from damage by external objects, thereby reducing resource loss;

[0041] The air valve 601 can release the air pressure in tank 1 when the air pressure is at its highest, thus preventing excessive air pressure and avoiding unnecessary accidents.

[0042] Specifically, in use, firstly, the worker places the workpiece to be annealed into the tank 100. Then, using external hoisting equipment and hook 504, the worker lifts the sealing cap 501 and transports it to the top of the tank 100. The worker then aligns the convex circle 502 with the inside of the tank 100 and slowly lowers the sealing cap 501 onto the top of the tank 100. At this point, the convex circle 502 positions the sealing cap 501 and simultaneously achieves a preliminary seal on the tank 100. For final sealing, the worker slightly rotates the sealing cap 501 to ensure that the U-shaped groove 503 on the sealing cap 501 is concentric with the screw 204. Then, the worker rotates the adjusting threaded rod 208. As the adjusting threaded rod 208 rotates, it will move under the action of the guide rod 209. The moving ring 211 moves upward, which in turn drives multiple sets of rotating racks 212 to move upward. As the rotating racks 212 move upward, they drive multiple sets of oscillating gears 210 to rotate. When the oscillating gears 210 rotate, they drive the oscillating shaft 203 and the screw 204 to rotate. When the screw 204 rotates, it enters the U-shaped slot 503. At this time, the operator can rotate the locking nut 205. When the locking nut 205 rotates, it drives the flattening 206 to move towards the sealing cover 501. As the locking nut 205 is slowly tightened, the sealing cover 501 is fixed to the tank 100. When it cannot be turned, the operator can use a pry bar to turn it. Place one end of the pry bar between the two sets of cylinders 207. Then, move one end of the pry bar to achieve secondary tightening.

[0043] After the pressure is tightened, the staff can then connect the vacuum pump to the first air pipe 300 and the second air pipe 400 to begin evacuating the tank 100. During evacuation, the pressure gauge 602 can be observed to determine if there is any leakage. If not, after a period of time, nitrogen can be injected into the tank 100 to facilitate the subsequent annealing process.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
