The annealing furnace is large in volume and heavy in quality, the base can provide stable support for the annealing furnace, ensure that it maintains a fixed position during the working process, prevent it from moving or tilting due to external force or its own thermal deformation, and thus ensure the normal operation and processing precision of the annealing furnace.

[0003] When the common annealing furnace is installed on the base and used for a long time, a large amount of heat will be generated during the working of the annealing furnace. If the heat cannot be dissipated in time, the temperature of the base will be too high, and the material properties of the base will decrease, such as the decrease of the strength and toughness of the steel, which can easily lead to deformation and cracking of the base, affecting the stability and service life of the annealing furnace.

[0007] As a further embodiment of this utility model: support rods are fixedly connected to all four sides of the base, and an annular heat dissipation pipe is fixedly connected to the top of the support rods. The outer wall of the annular heat dissipation pipe is fitted with evenly distributed heat dissipation fins, and a heat exhaust fan is installed on the top of one side of the annular heat dissipation pipe.

[0009] As a further improvement of this utility model: the outer wall of the base is provided with uniformly distributed heat dissipation fins.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] In this invention, when the heating plate is in close contact with the annealing furnace, the heating plate, with its excellent thermal conductivity, quickly absorbs the large amount of heat continuously generated by the annealing furnace.

[0018] 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.

[0019] Please see Figs. 1-5In this embodiment of the utility model, the base structure of the annealing furnace for oriented silicon steel processing includes a base 1. An annular groove 2 is formed in the upper part of the inner cavity of the base 1. Four heating plates 3 are slidably connected inside the annular groove 2. A circular groove 4 is formed in the bottom of the inner cavity of the base 1. A sliding plate 6 is slidably connected inside the circular groove 4. Output grooves 5 are formed on the four sides of the circular groove 4. Hinge seats 1 and 7 are fixedly connected to the four sides of the sliding plate 6. Connecting rods 8 are rotatably connected inside each of the four hinge seats 1 and 7, and the connecting rods 8 slide within the output grooves 5. Hinge seats 2 and 9 are fixedly connected to the relatively far sides of the four heating plates 3, and the hinge seats 2 and 9 are rotatably connected to the other end of the connecting rods 8. During installation, the annealing furnace is first placed inside the base 1 so that it contacts the sliding plate 6. The gravity of the annealing furnace causes the lower slide plate 6 to slide downwards along the circular groove 4. Simultaneously, the downward movement of the lower slide plate 6 causes the hinge seat 7 to move downwards, which in turn drives the connecting rod 8 to move downwards. During the sliding process within the hinge seat 9, the connecting rod 8 pushes the heating plate 3 to slide within the annular groove 2 and approach the annealing furnace, thus clamping the furnace. Each of the four heating plates 3 has a heating chamber 10 inside. A flow pipe 11 is slidably connected through and to the relatively close side of the four heating plates 3. When the four heating plates 3 slide close to each other, the flow pipe 11 slides within the heating chamber 10, allowing for heat exchange within the heating chamber 10. Limiting rings 12 are fixedly connected to the outer walls of both ends of the flow pipe 11 and the heating plate 3. Inside cavity 10, a connecting pipe 13 is fixedly connected to the middle of the side of the four heating plates 3 that are relatively far apart. The outer wall of the connecting pipe 13 passes through the base 1 and is fixedly connected. Limiting grooves 14 are opened in the inner cavity of the four connecting pipes 13. A limiting ring 15 is slidably connected to one side of the inner cavity of the four limiting grooves 14. A connecting pipe 16 is fixedly connected to the inner wall of the limiting ring 15 and passes through the connecting pipe 13. Support rods 17 are fixedly connected to all four sides of the base 1. An annular heat dissipation pipe 18 is fixedly connected to the top of the support rods 17. The outer wall of the annular heat dissipation pipe 18 is fitted with evenly distributed heat dissipation fins 19. After the heating plates 3 are tightly attached to the annealing furnace, they can efficiently absorb the large amount of heat generated by it. At this time, the exhaust fan 21 is turned on. The heat absorbed by the heating plate 3 flows sequentially through the heating cavity 10, connecting pipe 13, and connecting pipe 2 16 before entering the annular heat dissipation pipe 18 for heat dissipation. Multiple heat dissipation fins 19 on the outer wall of the annular heat dissipation pipe 18 can increase the heat dissipation area and improve the heat dissipation efficiency. A heat exhaust fan 21 is installed on the top of one side of the annular heat dissipation pipe 18. The four connecting pipes 2 16 pass through one side of the connecting pipe 13 and are fixedly connected to the annular heat dissipation pipe 18. When the heating plate 3 slides, it will drive the connecting pipe 13 to move synchronously. The limiting ring 2 15 inside the connecting pipe 13 and the connecting pipe 2 16 remain stationary. The two cooperate with each other to extend and limit the connecting pipe 13 when it moves. The outer wall of the base 1 is provided with evenly distributed heat dissipation fins 20.

[0020] The working principle of this utility model is as follows: During installation, the annealing furnace is first placed inside the base 1 so that it contacts the lower slide plate 6. The gravity of the annealing furnace will cause the lower slide plate 6 to slide down along the circular groove 4. At the same time, the downward movement of the lower slide plate 6 will drive the hinge seat 7 to move down synchronously, thereby driving the connecting rod 8 to move down. During the sliding process of the connecting rod 8 in the hinge seat 9, it pushes the heating plate 3 to slide in the annular groove 2 and approach the annealing furnace, thereby achieving the clamping of the annealing furnace.

[0021] After the heating plate 3 is tightly attached to the annealing furnace, it can efficiently absorb the large amount of heat generated by it. At this time, the exhaust fan 21 is turned on to absorb the heat absorbed by the heating plate 3. The heat flows through the heating chamber 10, the connecting pipe 13, and the connecting pipe 2 16 in sequence, and then enters the annular heat dissipation pipe 18 for heat dissipation. The multiple heat dissipation fins 19 provided on the outer wall of the annular heat dissipation pipe 18 can increase the heat dissipation area and improve the heat dissipation efficiency.

[0022] When the heating plate 3 slides, it will drive the connecting pipe 13 to move synchronously. The limiting ring 15 and the connecting pipe 16 inside the connecting pipe 13 remain stationary. The two cooperate with each other to extend and limit the connecting pipe 13 when it moves.

[0023] In addition, when the four heating plates 3 slide close to each other, the flow tube 11 slides inside the heating cavity 10, which can realize the mutual flow of heat inside the heating cavity 10.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
