Description

Technical Field

[0001] This utility model relates to the technical field of annealing furnace equipment, specifically, a water-sealed structure for a high-temperature annealing furnace. Background Technology

[0002] Traditional annealing furnace car bottom sealing methods often use sand filling to prevent hot gases from escaping from the furnace cavity and the gap between the furnace and the car. However, since the resulting sand layer is composed of multiple sand grains with gaps between them, high-temperature hot gases inside the furnace can leak out through these gaps, causing heat loss, increased energy consumption, and affecting the uniformity of temperature inside the furnace. Therefore, a more efficient and reliable sealing solution is urgently needed to address these issues. Utility Model Content

[0003] In order to overcome the defects of the existing technology, this utility model provides a water-sealed structure for a high-temperature annealing furnace to solve the problems in the existing technology.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a water-sealed structure for a high-temperature annealing furnace, including an annealing furnace, a furnace car is provided inside the furnace cavity of the annealing furnace, water-sealed parts are provided at the lower ends of both sides of the inner wall of the furnace cavity, and sealing plates are provided at the lower ends of both sides of the furnace car, with the sealing plates inserted into the water-sealed parts.

[0005] In the water-sealing structure of the high-temperature annealing furnace described above, the water-sealing part includes a sealing water tank with a U-shaped cross-section. One side of the sealing water tank is connected to the lower end of the inner wall of the annealing furnace, and the sealing plate is inserted into the sealing water tank.

[0006] In the water-sealed structure of the high-temperature annealing furnace described above, a gap is formed between the lower end face of the sealing plate and the lower inner end of the sealing water tank, and the sealing water tank is connected to a water inlet.

[0007] In the water-sealed structure of the high-temperature annealing furnace described above, the water inlet includes a main water inlet pipe, which is connected to multiple branch water pipes. The multiple branch water pipes are distributed and connected to the sealing water tanks on both sides, and each of the multiple branch water pipes is equipped with a switch valve.

[0008] In the water-sealing structure of the high-temperature annealing furnace described above, the sealing water tank extends downward relative to the inner wall of the furnace cavity, and the sealing plate extends downward relative to the two sides of the furnace car.

[0009] The beneficial effects of this utility model are that the sealing plate is inserted into the water-sealing part, and water is injected into the water-sealing part to seal the lower end of the furnace cavity and the space between the furnace cavity and the furnace car, preventing the interior of the furnace cavity from communicating with the outside world, thereby preventing the heat in the furnace cavity from dissipating outward. Compared with the traditional sand layer, the sealing performance is better, effectively preventing heat loss and increased energy consumption, while also preventing the uniformity of the furnace temperature from being affected.

[0013] Combination Figure 1 and Figure 2 The diagram shows a water-sealed structure for a high-temperature annealing furnace, comprising an annealing furnace 1, a furnace car 2 disposed within the furnace cavity of the annealing furnace 1, water-sealed portions disposed at the lower ends of both sides of the inner wall of the furnace cavity, and sealing plates 4 disposed at the lower ends of both sides of the furnace car 2, the sealing plates 4 being inserted into the water-sealed portions; in this embodiment, the sealing plates 4 are inserted into the water-sealed portions, and water is injected into the water-sealed portions to seal the lower end of the furnace cavity and the space between the furnace cavity and the furnace car, preventing communication between the interior of the furnace cavity and the outside, thereby preventing the heat from escaping from the furnace cavity. Compared with traditional sand layers, this structure provides better sealing, effectively preventing heat loss and increased energy consumption, while also preventing any impact on the uniformity of the furnace temperature.

[0014] The water sealing part includes a sealing water tank 3, which has a U-shaped cross-section. One side of the sealing water tank 3 is connected to the lower end of the inner wall of the annealing furnace 1, and the sealing plate 4 is inserted into the sealing water tank 3. By injecting water into the sealing water tank 3, the lower end of the sealing plate 4 is immersed in the water, thereby preventing the furnace cavity from communicating with the outside world and improving the sealing performance.

[0015] In this embodiment, a gap is formed between the lower end face of the sealing plate 4 and the lower inner end of the sealing water tank 3, and the sealing water tank 3 is connected to a water inlet. Water is injected into the sealing water tank 3 through the water inlet, so that the water can seal the entire lower surface of the sealing plate 4, thereby improving the sealing performance. Moreover, since the cross-section of the sealing water tank 3 is U-shaped, the sealing plate 4 divides the sealing water tank 3 into a U-shaped channel, and the injected water fills the U-shaped channel, which further improves the sealing performance. In addition, since the furnace car 2 moves in and out of the annealing furnace 1 during actual use, the traditional sand layer sealing structure is prone to other impurities mixing into the sand layer during actual application. At high temperatures, it may form clumps, which will affect the advancement of the furnace car 2. Moreover, the sand layer is not easy to replenish and is prone to overflow, eventually leading to the thinning of the sand layer and a decrease in sealing performance. The moving structure of the furnace car 2 in the annealing furnace 1 is prior art and will not be described in detail here.

[0016] It is worth noting that the water inlet section in this embodiment includes a main water inlet pipe 5, which is connected to multiple branch water pipes 6. The multiple branch water pipes 6 are distributed and connected to the sealed water tanks 3 on both sides. Each branch water pipe 6 is equipped with a switch valve. The switch valve can be used to open or close each branch water pipe 6 to facilitate the uniform injection of water into the sealed water tank 3.

[0017] It is also worth noting that in this embodiment, the sealing water tank 3 extends downward relative to the inner wall of the furnace cavity, and the sealing plate 4 extends downward relative to the two sides of the furnace car 2; so that the entire water sealing part is located outside the furnace cavity and the furnace car, preventing the entire water sealing part from being at high temperature inside the furnace cavity, causing the entire water surface to be heated and evaporate in large quantities inside the furnace cavity, and the formed U-shaped channel can reduce the water surface area on one side of the furnace cavity.

[0018] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
