Technical Field
[0001] This utility model relates to the field of gas circulation technology, and in particular to a gas circulation device for cooling metal coating materials during heat treatment. Background Technology
[0002] Heat treatment of metal coating materials is a key technology that improves the bonding strength between the coating and the substrate, as well as the coating's microstructure and properties (such as hardness, wear resistance, and corrosion resistance) through heating and cooling processes. After heat treatment, metal coating materials need to be cooled using a gas circulation cooling device. Existing cooling gas circulation devices are inconvenient to filter the circulating gas during use, allowing the gas to pass directly through the heat exchanger and into the cooling chamber via the fan. This makes the fan impeller susceptible to wear from particulate impurities in the gas, and prolonged use can easily damage the fan, thus affecting the circulation efficiency of the cooling gas and reducing the cooling effect on the metal coating, thereby shortening the service life of the device. Therefore, this utility model proposes a cooling gas circulation device for heat treatment of metal coating materials to solve the above problems. Utility Model Content

[0013] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0014] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes a cooling gas circulation device for heat treatment of metal coating materials, including a cooling chamber 1. A mounting rack 2 is installed inside the cooling chamber 1. A mounting plate 3 is installed on one side of the cooling chamber 1. A fan 4 is installed at the top of the mounting plate 3. An air supply pipe 5 is installed at one end of the fan 4. Air jets 6 are installed obliquely on both sides inside the cooling chamber 1. One end of the air supply pipe 5 is connected to one end of each air jet 6. An air outlet pipe 7 is installed on one side of the top of the cooling chamber 1. An air return pipe 8 is installed at the top of the air outlet pipe 7. A heat exchanger 9 is installed at the middle position of the top of the cooling chamber 1. One end of the air return pipe 8 is connected to one side of the heat exchanger 9. A filter chamber 10 is installed above one side of the cooling chamber 1. One end of the heat exchanger 9 is connected to the filter chamber 1 via a pipe. One side of the filter chamber 10 is connected to the filter 10. The filter chamber 10 is equipped with a filter mechanism. A cleaning mechanism is provided on one side of the filter chamber 10. A connecting pipe 11 is installed at the bottom of the filter chamber 10. One end of the connecting pipe 11 is connected to one end of the fan 4. When in use, the workpiece to be cooled is placed on the placement rack 2 and the cooling chamber 1 is closed. At this time, the fan 4 is started, and the workpiece is cooled by air through the air supply pipe 5 and the air jet 6. The hot air generated during cooling enters the interior of the heat exchanger 9 through the air outlet pipe 7 and the air return pipe 8. The heat exchanger 9 is used to cool the air. Then the cooled air enters the interior of the filter chamber 10. After filtration, the air enters the interior of the fan 4 through the connecting pipe 11. The fan 4 and the air supply pipe 5 blow the air into the interior of the air jet 6. The air jet 6 blows the air out to cool the workpiece.
[0015] The filtration mechanism includes a first filter plate 14, a second filter plate 15, a fixed groove 16, and a movable rail 17. The first filter plate 14 is installed on one side inside the filter chamber 10, and the second filter plate 15 is installed on the other side inside the filter chamber 10. Fixed grooves 16 are provided at both the top and bottom of the filter chamber 10. A movable rail 17 is installed inside each fixed groove 16, with one end of the movable rail 17 connected to one end of the second filter plate 15. The cross-section of the fixed groove 16 is larger than the cross-section of the movable rail 17, and a sliding structure is formed between the fixed groove 16 and the movable rail 17. The aperture of the first filter plate 14 is larger than the aperture of the second filter plate 15. During use, the cooled air... Inside the filter chamber 10, the air undergoes dual filtration using the first filter plate 14 and the second filter plate 15, filtering out some particles in the air. Simultaneously, the fixed groove 16 and the movable rail 17 allow for easy disassembly and installation of the first filter plate 14 and the second filter plate 15, making replacement or cleaning more convenient and quick. This filtration of circulating air and particles reduces the risk of damage to the impeller of the fan 4 during use, resulting in higher cooling gas circulation efficiency and better cooling of the metal coating, thus greatly improving the practicality of the device.
[0016] The cleaning mechanism includes a discharge port 13, a mounting cavity 18, a servo motor 19, a threaded rod 20, a threaded block 21, a connecting rod 22, and a cleaning brush 23. The discharge port 13 is located on one side below the filter cavity 10. The mounting cavity 18 is installed at the rear end inside the filter cavity 10. The servo motor 19 is installed at the bottom end of the mounting cavity 18. The threaded rod 20 is installed inside the mounting cavity 18. The output end of the servo motor 19 is connected to one end of the threaded rod 20. A threaded block 21 is provided on the outer wall of the threaded rod 20. A connecting rod 22 is installed at one end of the threaded block 21. A cleaning brush 23 is installed at one end of the connecting rod 22. One side of the cleaning brush 23 is in contact with one side of the first filter plate 14. The threaded block 21 has a square design. The mounting cavity 18 and the threaded block 21 form a sliding structure. A dustproof box can be set on the outside of the servo motor 19 for dust prevention. When in use, the servo motor 19 is started to drive the threaded rod 20 to rotate, which causes the threaded block 21 to slide inside the mounting cavity 18, thereby driving the cleaning brush 23 to slide. The cleaning brush 23 is used to clean the first filter plate 14, making the first filter plate 14 less prone to clogging during use. Therefore, the filtration effect of the first filter plate 14 is better, which greatly improves the overall performance during use.
[0017] A receiving box 12 is installed on one side below the filter chamber 10. The receiving box 12 is positioned corresponding to the discharge port 13. When in use, the discharge port 13 is opened, and the receiving box 12 is used to store and process dust particles and waste.
[0018] Working principle: The operator first places the workpiece to be cooled on the rack 2 and closes the cooling chamber 1. At this time, the fan 4 is started, and the workpiece is cooled by air through the air supply pipe 5 and the air nozzle 6. The hot air generated during cooling enters the heat exchanger 9 through the air outlet pipe 7 and the air return pipe 8. The heat exchanger 9 cools the air, and then the cooled air enters the filter chamber 10. The first filter plate 14 and the second filter plate 15 perform double filtration of the air to filter out some particles. Finally, the air enters the fan 4 through the connecting pipe 11 and is blown into the air nozzle 6 by the fan 4 and the air supply pipe 5. The jet nozzle 6 blows out to circulate and cool the workpiece. When the first filter plate 14 needs to be cleaned after long-term use, the servo motor 19 is started to drive the threaded rod 20 to rotate, which in turn drives the threaded block 21 to slide inside the mounting cavity 18, thereby driving the cleaning brush 23 to slide. The cleaning brush 23 is used to clean the first filter plate 14. At this time, the discharge port 13 is opened, and the dust falls into the receiving box 12 for collection and treatment. At the same time, the first filter plate 14 and the second filter plate 15 can be easily disassembled and installed by using the cooperation of the fixed groove 16 and the movable rail 17, making it more convenient and faster to replace or clean the first filter plate 14 and the second filter plate 15.
