Description

Technical Field

[0001] This utility model relates to the field of brazing furnace technology, and in particular to a drying structure for a brazing furnace. Background Technology

[0002] Brazing is a joining process that uses a filler metal with a melting point lower than that of the base metal to fill the gap between the joints and form a metallurgical bond. It has the characteristics of small deformation, beautiful joints, and wide applicability to materials.

[0003] Brazing requires the use of a brazing furnace, which includes a drying oven. The purpose of the drying oven is to ensure that the workpiece is thoroughly dried after passing through it. The degree of dryness of the workpiece directly affects the brazing quality.

[0004] Existing brazing furnaces mostly use air blowing to dry the workpieces, and the drying effect is improved by controlling the air volume of the blowing. However, this process has limited effect on improving the drying effect of the workpieces.

[0005] To ensure good drying of the workpiece, the existing structure needs to be improved. Utility Model Content

[0006] The present invention aims to overcome the shortcomings of poor drying effect in the prior art and provides a drying structure for brazing furnaces with good drying effect.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a drying structure for a brazing furnace, comprising:

[0008] The drying chamber is equipped with several partition curtains, which divide the drying chamber into several drying chambers, each corresponding to a different drying temperature.

[0009] A lower air blowing block is installed at the bottom of the drying chamber;

[0010] A side-blowing block is slidably installed on the side wall of the drying chamber, and a heating rod is provided inside the side-blowing block;

[0011] An exhaust pipe is installed on the top of the drying chamber and is connected to the drying cavity.

[0012] This drying structure includes a drying chamber with several partition curtains inside, dividing the chamber into multiple drying cavities. This structure ensures the drying chamber is a cavity structure, and the divided drying cavities correspond to different drying temperatures, allowing for drying of workpieces at varying temperatures and thus improving drying efficiency. The structure also includes a downward blowing block installed at the bottom of the drying cavity, which blows air upwards to dry the bottom of the workpiece. Additionally, the structure includes side blowing blocks that slide along the inner wall of the drying cavity. Adjusting the position of these blocks allows for adjusting the airflow direction, enabling drying of the workpiece from different angles. Heating rods are installed inside the side blowing blocks to heat the air blown out, further enhancing the drying effect. Meanwhile, an exhaust pipe is installed on the drying structure and is mounted on the top of the drying chamber. The exhaust pipe can vent the air in the drying chamber, enabling gas convection within the drying chamber and thus improving the drying effect.

[0013] Preferably, the separating curtain includes a fixed curtain with a clearance hole in the middle for the conveyor belt to pass through. Several swing curtains are installed at the top of the clearance hole, and magnetic blocks are installed on the sidewalls of adjacent swing curtains.

Several swing curtains are installed at the top of the clearance hole, allowing them to swing. When the conveyor belt carries a workpiece through the clearance hole, the support on the conveyor belt and the workpiece push the swing curtains through the clearance hole and into the drying chamber. Simultaneously, magnetic blocks are installed on the sidewalls of adjacent swing curtains to attract them, ensuring that the swing curtains open when a workpiece passes through and immediately return to their original position afterward. This ensures the drying chamber is a sealed cavity structure, guaranteeing good drying results.

[0014] Preferably, the inner wall of the drying chamber is provided with several embedded slots, each of which is placed in a corresponding drying cavity. The lower air blowing block is installed at the bottom of the embedded slot, and the lower air blowing block is provided with an air blowing channel.

The drive gear meshes with the rack, so the side blowing block can be moved by the rotation of the drive gear, that is, the position of the side blowing block can be adjusted, and the blowing direction can be adjusted so that the blowing direction is towards the workpiece, thereby improving the blowing drying effect.

[0016] Preferably, the side-blowing block is an arc-shaped block with several air-blowing holes on its inner wall and an air-blowing chamber inside.
