Description

Technical Field

[0001] This utility model belongs to the field of annealing furnace cooling technology, and in particular relates to a cooling device for an annealing furnace. Background Technology

[0002] Steel plate is a flat steel material with a large width-to-thickness ratio. The term "plate" usually refers to products cut to a fixed length. Depending on the thickness, steel plates can be roughly divided into three categories: medium and heavy plates, thin plates, and foils. From the perspective of the characteristics of the rolling deformation process, thin steel plates and strips have two fundamentally different production methods—hot rolling and cold rolling.

[0003] After hot-rolled strip steel is annealed, it usually needs to be cooled to a specific temperature before the next process can be carried out. However, excessively fast cooling can cause severe warping and deformation of the strip steel. Most existing cooling devices directly cool the annealing furnace through the outside air. When the outside air temperature is too high, the cooling process is not fast or convenient enough, which greatly reduces the applicable range of the cooling device. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a cooling device for an annealing furnace, which can effectively solve the problems of the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] A fixed plate is fixed inside the main compartment. An active rod is set in the center of the fixed plate, and driven rods are symmetrically arranged on the left and right sides of the active rod.

[0009] The drive mechanism is located on one side of the drive rod and is used to drive the drive rod to rotate at multiple angles.

[0010] The air ducts are evenly distributed on one side of the main compartment, and the fan body is fixed at the end of the driving rod and driven rod away from the air duct;

[0011] The refrigeration unit, located inside the main compartment, is used to cool the air entering the main compartment.

[0012] Furthermore, the adjustment mechanism includes a connector, an adjusting screw, and a synchronous motor. The connector is fixed at both ends of the main body compartment, the adjusting screw is threaded to the inside of the connector, and the synchronous motor is symmetrically fixed on the upper end face of the lifting frame, with the output end of the synchronous motor connected to the adjusting screw.

[0013] Furthermore, drive gears are uniformly fixed on the outer surfaces of the driving rod and the driven rod, and a gear belt is sleeved on the outer surface of the drive gears.

[0014] Furthermore, the drive mechanism includes a connecting gear and a servo motor. The connecting gear is fixed on the outer surface of the driven rod near the fan body. The servo motor meshes with the connecting gear through a linkage gear, and the other end of the servo motor is fixed to the fixed plate.

[0015] Furthermore, a cleaning brush is fixed to one end of the driven rod away from the fan body, and the other end of the cleaning brush is in contact with the filter screen in the air duct.

This further expands the main chamber's applicability. The drive mechanism, in conjunction with a gear belt, rotates the active and driven rods, guiding gas through the fan. The guided gas then passes through the cooling pipes, rapidly cooling the workpieces within the annealing furnace and facilitating subsequent processing. Simultaneously, the rotation of the active and driven rods cleans the air duct with a cleaning brush, preventing dust particles from accumulating on the filter screen and affecting subsequent gas cooling.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-3 As shown, this utility model is a cooling device for an annealing furnace, including a main chamber 1 and lifting frames 3 arranged on the left and right sides of the main chamber 1, and also includes:

[0027] An adjustment mechanism is installed on the left and right sides of the lifting frame 3 to adjust the position of the main chamber 1 as needed. The adjustment mechanism includes a connector 2, an adjusting screw 4, and a synchronous motor 5. The connector 2 is fixed at the left and right ends of the main chamber 1. The adjusting screw 4 is threaded to the inner side of the connector 2. The synchronous motor 5 is symmetrically fixed on the upper end face of the lifting frame 3, and the output end of the synchronous motor 5 is connected to the adjusting screw 4. The two sets of synchronous motors 5 can rotate simultaneously. When the synchronous motor 5 rotates, it can drive the adjusting screw 4 to rotate accordingly. Since the main chamber 1 can be connected to the adjusting screw 4 through the connector 2, when the adjusting screw 4 rotates, the main chamber 1 can slide up and down to adjust. This allows the cooling device to be used with tempering furnaces of different specifications, thus further expanding the applicability of the main chamber 1.

[0028] The fixed plate 6 is fixed inside the main body compartment 1. The fixed plate 6 has an active rod 7 in the center and driven rods 8 are symmetrically arranged on the left and right sides of the active rod 7.

[0029] The drive mechanism is located on one side of the drive rod 7 and is used to drive the drive rod 7 to rotate at multiple angles. The drive mechanism includes a connecting gear 10 and a servo motor 11. The connecting gear 10 is fixed on the outer surface of the driven rod 8 near the fan body 12. The servo motor 11 meshes with the connecting gear 10 through a linkage gear, and the other end of the servo motor 11 is fixed to the fixed plate 6. The servo motor 11 can drive the linkage gear it outputs to rotate. One side of the linkage gear is connected to the connecting gear 10. When the linkage gear rotates, the connecting gear 10 can rotate accordingly.

[0030] The air duct 13 is evenly distributed on one side of the main chamber 1. The end of the drive rod 7 and driven rod 8 away from the air duct 13 is fixed with a fan body 12. Drive gears are evenly fixed on the outer surfaces of the drive rod 7 and driven rod 8. A gear belt 9 is sleeved on the outer surface of the drive gear. The drive rod 7 can be rotated by the connecting gear 10. When the drive rod 7 rotates, the two sets of driven rods 8 can be rotated by the gear belt 9. Then, the air can be guided into the main chamber 1 by the fan body 12 for subsequent processing. A cleaning brush 14 is fixed on the end of the driven rod 8 away from the fan body 12. The other end of the cleaning brush 14 is in contact with the filter screen in the air duct 13. When the drive rod 7 and driven rod 8 rotate, the cleaning brush 14 can also clean the air duct 13, which can prevent dust particles from appearing on the filter screen in the air duct 13 and affecting the subsequent gas cooling.

[0031] The refrigeration mechanism, located inside the main chamber 1, is used to cool the air entering the main chamber 1. The refrigeration mechanism includes a refrigeration component 15, a connecting pipe 16, and refrigeration pipes 17. The refrigeration component 15 is fixed to the upper surface of the main chamber 1. The connecting pipe 16 is connected to the tail end of the refrigeration component 15. Three sets of refrigeration pipes 17 are evenly arranged and connected to the tail end of the connecting pipe 16. The refrigeration pipes 17 are spirally arranged and maintain the same vertical center line as the fan body 12. The refrigeration component 15 can cool the water, which is then guided into the refrigeration pipes 17 through the connecting pipe 16. Because the refrigeration pipes 17 are spirally arranged and maintain the same vertical center line as the fan body 12, they can quickly cool the air without affecting the air guidance. This avoids the problem of insufficient cooling speed and convenience when the outside air temperature is too high, thereby further expanding the applicability of the equipment.

[0032] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
