Description

Technical Field

[0001] This utility model relates to the field of hot-dip galvanized workpiece production technology, and in particular to a multi-stage cooling system for hot-dip galvanized workpieces. Background Technology

[0002] Hot-dip galvanizing involves immersing steel in molten zinc at high temperatures, causing the iron substrate and pure zinc layer to form a metallurgical bond through an iron-zinc alloy, resulting in a dense coating of approximately 35 micrometers or more. This coating effectively isolates moisture and oxygen and slows corrosion through an electrochemical protection mechanism. However, hot-dip galvanized workpieces require water bath cooling during production. Because the water in the cooling bath boils rapidly during mass production, the cooling effect of hot water is greatly reduced, significantly impacting the appearance quality of the galvanized workpiece. Furthermore, frequent water changes in the cooling bath significantly affect galvanizing production efficiency and waste water resources, thus reducing the overall effectiveness.

[0013] The drive assembly allows the drive motor to rotate the drive rod and drive gear. The drive gear then moves the assembly housing on the assembly ring along the direction of the assembly conical housing, causing the tooling material inside the assembly housing to rotate centrifugally. This allows cold air to pass thoroughly through the assembly filter on the assembly housing, effectively cooling the tooling material on the hollow auger. The movable assembly allows the movable motor to rotate the movable pulley, which in turn rotates the connecting blowpipe on the connecting pulley via a belt. This adjusts the connecting blowpipe to a suitable angle, allowing the air discharged from the connecting blowpipe to evenly contact and cool the connecting serpentine tube and the spiral guide tube, thus effectively cooling the tooling material on the hollow auger. Cooling is achieved through a multi-stage cooling system. The installation assembly allows a fan to drive air through an installation blowpipe into the U-shaped installation tube. The air then flows through both ends of the U-shaped tube into corresponding connecting blowpipes and is subsequently discharged. The air then condenses in the connecting serpentine tube. The cooled air is further cooled by passing through a spiral duct. Finally, the cold air passes through a filter on the assembly housing, cooling the tooling material on the hollow auger. A fixed assembly allows a moving motor to rotate a moving gear on a moving rod. This moving gear, in turn, rotates the fixed blowpipe on the fixed gear to a suitable angle, adjusting the cooling of the discharged material. This multi-stage cooling improves the overall performance. Attached Figure Description

An installation blowpipe 14 is fixedly connected to the air outlet of the installation fan 13. An installation U-shaped pipe 16 is fixedly connected to the end of the installation blowpipe 14. The two ends of the installation U-shaped pipe 16 are rotatably connected to one end of the corresponding connecting blowpipe 12. An installation branch pipe 15 is fixedly connected to the top of the installation blowpipe 14. The end of the installation branch pipe 15 is rotatably connected to one end of the assembled hollow auger 5. A fixed branch pipe 21 is fixedly connected to the bottom of the installation U-shaped pipe 16. A support sleeve 26 is fixedly sleeved on the outer wall of the conical shell 1.

[0024] A fixed assembly for rotating the fixed gear 22 is connected to the side wall of the support sleeve 26. The fixed assembly includes a movable bracket 23 fixedly connected to the side wall of the support sleeve 26. A movable motor 24 is fixedly connected to the side wall of the movable bracket 23. A movable rod is fixedly connected to the output end of the movable motor 24. The end of the movable rod passes through the movable bracket 23 and is fixedly connected to the movable gear 25.

An assembly valve is connected to the outer wall of the assembly conical housing 1. The fixed assembly is used to drive the fixed gear 22 to rotate.

[0025] Working principle: In use, the workpiece material is first poured into the assembly feed hopper 3 and falls above the assembly hollow auger 5. Then, the workpiece material moves downwards by its own weight in a spiral motion. At the same time, one end of the spiral guide tube 9 is connected to the outlet of the external water pump, and the other end of the spiral guide tube 9 is connected to the external water storage tank. The water pump is started to discharge water into the spiral guide tube 9. Then, the condenser 27 is started to condense the water passing through the spiral guide tube 9. Since the spiral guide tube 9 is connected to two connecting serpentine pipes 11, the cooled water is also discharged into the corresponding connecting serpentine pipes 11. Finally, the cooled water is discharged into the external water storage tank through the spiral guide tube 9.

[0026] Simultaneously, the installation fan 13 is started, and the installation fan 13 drives the air through the installation blowpipe 14 and into the installation U-shaped pipe 16. Then, the air is discharged through the two ends of the installation U-shaped pipe 16 into the corresponding connecting blowpipe 12 and then discharged through the connecting blowpipe 12. The air is condensed through the connecting serpentine pipe 11. Then, the cooled air is cooled again through the spiral duct 9. Then, the cold air passes through the assembly filter screen on the assembly housing 2, so as to blow and cool the tooling materials on the hollow auger 5 in the assembly.

[0027] Then, the movable motor 18 is started, which drives the movable rod and the movable pulley 19 to rotate. Then, the movable pulley 19 drives the connecting blowpipe 12 on the connecting pulley to rotate via the belt, so that the connecting blowpipe 12 is adjusted to a suitable angle. Then, the air discharged from the connecting blowpipe 12 comes into contact with the connecting serpentine tube 11 and the spiral guide tube 9 evenly for cooling, thereby fully cooling the tooling materials on the assembly hollow auger 5.

[0028] Because the installation branch pipe 15 is installed on the installation blowpipe 14, and the installation branch pipe 15 is rotatably installed with one end of the assembly hollow auger 5, a portion of the air inside the installation blowpipe 14 is also discharged into the assembly hollow auger 5 through the installation branch pipe 15, and then discharged from multiple assembly blow holes on the assembly hollow auger 5, thereby blowing and cooling the tooling materials on the assembly hollow auger 5.

[0029] Simultaneously, the drive motor 7 is started, which drives the drive rod and drive gear 8 to rotate. Then, the drive gear 8 also drives the assembly housing 2 on the assembly gear ring 6 to move along the direction of the assembly conical housing 1, causing the tooling material inside the assembly housing 2 to rotate centrifugally. This allows the cold air to pass fully through the assembly filter on the assembly housing 2, thus regulating and cooling the tooling material on the assembly hollow auger 5. Finally, the assembly valve on the assembly conical housing 1 is activated, allowing the tooling material that has undergone multi-stage cooling to fall into the bottom of the assembly conical housing 1 through the assembly housing 2 and be discharged through the assembly conical housing 1.

[0030] Then, a portion of the air inside the U-shaped tube 16 is discharged into the fixed blowpipe 20 through the fixed branch pipe 21, and then discharged from the fixed blowpipe 20, which further cools the discharged workpiece material. Then, the moving motor 24 is started, which drives the moving gear 25 on the moving rod to rotate. Then, the moving gear 25 also drives the fixed blowpipe 20 on the fixed gear 22 to rotate to a suitable angle, thereby adjusting the cooling of the discharged material.
