Description

Technical Field

[0001] The utility model relates to the field of annealing furnaces, in particular to a side-blowing annealing furnace. Background Art

[0002] The working principle of a side-blown annealing furnace is primarily based on side-blowing technology. By blowing hot air or oxygen-enriched air into the side of the material in the furnace, the material is heated and annealed. During the heating process, the hot air or oxygen-enriched air fully contacts the material, gradually raising the material temperature to the required annealing temperature range. Subsequently, by controlling the cooling rate, the internal structure and properties of the material are adjusted and optimized.

[0003] The main structure of the side-blown annealing furnace includes the furnace body, heating system, cooling system, control system and other parts. Among them, the furnace body is usually made of refractory materials and can withstand high temperatures and the erosion of materials in the furnace. The heating system is responsible for providing hot air or oxygen-enriched air to achieve heating of the materials.

[0004] When a side-blown annealing furnace is in use, a hot air blower on the side is used to blow hot air into the furnace to facilitate heating. However, the direction of the hot air flow is single. When the hot air is blown into the furnace, the heating is uneven, which makes the air flow distribution uneven, and easily causes uneven heating, thereby affecting the annealing effect. Therefore, a side-blown annealing furnace is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a side-blown annealing furnace, including an annealing furnace body 1, which provides a support and protection frame for the entire annealing furnace and accommodates other components to ensure that the annealing process is carried out in a relatively stable environment and can provide heat during the annealing process. A protective door 2 is provided on the front side of the annealing furnace body 1, which plays a role of sealing and heat insulation, preventing heat loss and external impurities from entering the annealing furnace and affecting the annealing effect. The inner wall of the annealing furnace body 1 is provided with a furnace body 3, which is made of refractory material to provide a suitable high-temperature environment for the workpiece and realize the heating and insulation functions required for the annealing process. Ventilation slots 4 are provided on the right side of the furnace body 3, and multiple groups are provided to allow airflow to pass through, provide ventilation for the interior of the annealing furnace, ensure the circulation of gas in the furnace and uniform distribution of heat. A swing assembly is provided on the right inner wall of the annealing furnace body 1, and the swing assembly includes a rotating rod 51. The rotating rod 51 is rotatably connected to the inner wall of the ventilation slot 4 and rotates under the action of the driving assembly, thereby driving the air guide plate 55 to swing and adjust the direction and distribution of the airflow in the furnace.

[0032] Furthermore, an air guide plate 55 is fixedly connected to the inner wall of the rotating rod 51. The air guide plate 55 is made of alumina ceramic material and can work in a high-temperature environment in the furnace. By swinging, the direction of the airflow in the furnace is adjusted, so that the heat is more evenly distributed in the furnace body 3, thereby improving the annealing effect. At the same time, when the air guide plate 55 swings to the upper and lower end points, the ventilation slot 4 can be blocked, thereby reducing heat dissipation and ensuring the stability of the temperature in the furnace. A connecting block 52 is fixedly connected to the inner wall of the furnace body 3 on the rear side of the rotating rod 51, which converts the linear motion of the moving bar 53 into the rotation of the rotating rod 51. A sliding groove 56 is provided on the inner wall of the connecting block 52 to provide a moving space for the fixed column 54, thereby driving the connecting block 52 to move up and down. A driving component is provided on the rear side of the annealing furnace body 1. The driving component includes a servo motor 63, which provides a power source to drive the rotating plate 62 to rotate. The servo motor 63 is fixed to the rear side of the annealing furnace body 1.

[0033] Reference Figure 2 - Figure 4 The swing assembly also includes a moving bar 53, which moves vertically up and down under the action of the driving assembly, and drives the connecting block 52 to move through the fixed column 54. At the same time, the guide column 61 moves downward through the gravity of the moving bar 53. The inner wall of the left side of the moving bar 53 is slidably connected to the right side of the furnace body 3. The front side of the moving bar 53 is fixedly connected to a fixed column 54 as a medium connecting the moving bar 53 and the connecting block 52, transmitting the movement of the moving bar 53 to the connecting block 52. The outer side of the fixed column 54 slides on the inner wall of the slide groove 56. There are multiple groups of fixed columns 54, and the outer side of the connecting block 52 slides on the inner wall of the furnace body 3.

[0034] Reference Figure 3 and Figure 4 The driving assembly also includes a rotating plate 62, which is arranged in a cam shape. When the servo motor 63 drives the rotating plate 62 to rotate, the outer side of the rotating plate 62 cooperates with the guide column 61 to convert the rotational motion of the rotating plate 62 into a vertical reciprocating motion of the moving bar 53. The gravity of the moving bar 53 causes the guide column 61 to move downward and fit into the outer side of the rotating plate 62. The rear side of the rotating plate 62 is fixedly connected to the front side of the output shaft of the servo motor 63, and the rear side of the moving bar 53 is fixedly connected to the guide column 61, which transmits the motion of the rotating plate 62 to the moving bar 53 to guide the movement of the moving bar 53. The outer side of the guide column 61 slides on the outer side of the rotating plate 62. The rear part of the furnace body 3 is fixedly connected to the inner wall of the annealing furnace body 1 with an isolation plate 7, which is set as a heat insulation material to play a role of isolation and protection, preventing the heat from the rear of the furnace body 3 from affecting the swing assembly, and also helping to maintain the temperature stability in the furnace.

[0035] Working Principle: During operation, when the annealing furnace begins operating, the servo motor 63 activates, driving the cam-shaped rotating plate 62 to rotate. The outer side of the rotating plate 62 engages with the guide post 61, converting the rotating motion of the rotating plate 62 into vertical reciprocating motion of the moving bar 53. The inner wall of the left side of the moving bar 53 slides onto the right side of the furnace body 3, ensuring its stable movement.

[0036] Multiple sets of fixed posts 54 on the front side of the movable bar 53 move up and down with the movable bar 53, driving the connecting block 52 up and down. The connecting block 52 is fixed to the rear side of the rotating rod 51 and slides on the inner wall of the furnace body 3. The up and down movement of the connecting block 52 causes the rotating rod 51 to rotate on the inner wall of the ventilation slot 4. The rotation of the rotating rod 51 causes the air guide plate 55 to swing.

[0037] The air guide plate 55 adjusts the direction of the airflow in the furnace during the swinging process, so that the heat is more evenly distributed in the furnace body 3, thereby improving the annealing effect.

[0038] When heating is not required, the air guide plate 55 swings to the upper and lower end points to block the ventilation slots 4, reduce heat dissipation, and ensure the stability of the temperature in the furnace.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
