[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see the appendix Figure 1-5 This application provides the following technical solutions.

[0024] A drying device includes a drying mechanism 1, with a conveying mechanism 2 inside the drying mechanism 1. The drying mechanism 1 includes an isolation cover 12, with three fixed cylinders 25 fixedly connected to the lower inner wall of the isolation cover 12. Guide rollers 24 are rotatably connected to the inner walls of the three fixed cylinders 25. A conveyor belt 22 is provided on the outer wall of the guide rollers 24. A cleaning component 26 is provided on the top of each of the three fixed cylinders 25. The cleaning component 26 includes a high-pressure air duct 261, with the bottom of the high-pressure air duct 261 fixedly connected to the fixed cylinder 25. A connecting pipe 27 is provided on one side of the high-pressure air duct 261. Cleaning nozzles 262 are provided on both sides of the high-pressure air duct 261. A cleaning scraper 263 is provided on the top of the high-pressure air duct 261, with both sides of the cleaning scraper 263 in contact with the conveyor belt 22.

[0025] It should be noted that when the contact surface of the conveyor belt 22 and the crankshaft passes through the depression caused by the guide roller 24, the cleaning scraper 263 scrapes away the water stains and dirt remaining on the contact surface of the conveyor belt 22. At the same time, the high-pressure gas transfer box 14 injects high-pressure gas into the connecting pipe 27. The high-pressure gas enters the high-pressure air pipe 261 through the connecting pipe 27 and is discharged from the cleaning nozzle 262 through the distribution of the high-pressure air pipe 261, which impacts and cleans the dirt remaining in the vent holes on the surface of the conveyor belt 22.

[0026] The conveyor belt 22 has several ventilation holes. Six hollow drive rollers 23 are arranged on the inner side of the conveyor belt 22. The two ends of the six hollow drive rollers 23 are rotatably connected to the isolation cover 12. The guide roller 24 is arranged below between two hollow drive rollers 23. The top outer side of the conveyor belt 22 is in contact with the lower end of the guide roller 24. The conveyor belt 22 is squeezed by the hollow drive rollers 23 and the guide roller 24 and is concave. The width of the concave shape is smaller than the width of the crankshaft.

[0027] It should be noted that when the crankshaft passes through the recess formed by the two hollowed-out transmission rollers 23 and a high-pressure gas transfer box 14, the contact surface between the crankshaft and the conveyor belt 22 is fully exposed, and hot air from the bottom up dries the contact surface of the crankshaft.

[0028] A high-pressure gas adapter box 14 is fixedly connected to one side of the isolation cover 12. The output end of the high-pressure gas adapter box 14 is fixedly connected to the connecting pipe 27. The ends of the three connecting pipes 27 away from the high-pressure gas adapter box 14 are respectively fixedly connected to three high-pressure air pipes 261.

[0029] It should be noted that when the contact surface of the conveyor belt 22 and the crankshaft passes through the depression caused by the guide roller 24, the cleaning scraper 263 scrapes away the water stains and dirt remaining on the contact surface of the conveyor belt 22. At the same time, the high-pressure gas transfer box 14 injects high-pressure gas into the connecting pipe 27. The high-pressure gas enters the high-pressure air pipe 261 through the connecting pipe 27 and is discharged from the cleaning nozzle 262 through the distribution of the high-pressure air pipe 261. This impacts and cleans the dirt remaining in the vent holes on the surface of the conveyor belt 22. After the contact surface of the conveyor belt 22 is cleaned, it contacts the crankshaft again, driving the crankshaft through the drying mechanism 1 and out of the outlet, completing the drying work of the parts.

[0030] A hot air blower 13 is connected through the top of the isolation cover 12, and a mounting frame 11 is fixedly connected to the bottom of the isolation cover 12. A return air guide shroud 15 is fixedly connected to the inner wall of the mounting frame 11. A motor 16 is fixedly connected to one corner of the top of the inner wall of the mounting frame 11. A transmission roller 21 is fixedly connected to the output end of the motor 16. The end of the transmission roller 21 away from the motor 16 is rotatably connected to the mounting frame 11. Another transmission roller 21 is rotatably connected to the inner wall of the end of the mounting frame 11 away from the transmission roller 21. Both transmission rollers 21 are set on the inner wall of the conveyor belt 22.

[0031] It should be noted that after starting the hot air blower 13 and the high-pressure gas transfer box 14, the cleaned or heat-treated crankshaft is placed on top of the inlet end of the conveyor mechanism 2 outside the drying mechanism 1. The motor 16 is started, driving the transmission roller 21 to rotate. The transmission roller 21 drives the conveyor belt 22 to rotate, which in turn drives the hollow transmission roller 23 and guide roller 24 to rotate. The crankshaft enters the drying mechanism 1, and the hot air discharged from the hot air blown by the hot air blower 13 onto the surface of the crankshaft, removing moisture and dirt from the crankshaft. The hot air is carried through the ventilation holes on the conveyor belt 22 and falls into the interior of the return air guide shroud 15. It is discharged from the through slot at the bottom of the return air guide shroud 15. At the same time, the hot air discharged from the hot air blower 13 blows into the interior of the return air guide shroud 15. It is guided by the curvature of the inner wall of the return air guide shroud 15, and then passes through the conveyor belt 22 from the bottom to dry the crankshaft and flow back to the top. It is then guided by the curvature of the inner wall of the isolation cover 12. The hot air circulates in the space formed between the mounting bracket 11, the isolation cover 12, and the return air guide shroud 15.

[0032] A vehicle-mounted air compressor crankshaft processing equipment, which includes the aforementioned drying device.

[0033] During operation, the operator first starts the hot air blower 13 and the high-pressure gas transfer box 14. Then, the cleaned or heat-treated crankshaft is placed on top of the inlet end of the conveyor mechanism 2 outside the drying mechanism 1. The motor 16 is started, driving the transmission roller 21 to rotate. The transmission roller 21 drives the conveyor belt 22 to rotate, which in turn drives the hollow transmission roller 23 and guide roller 24 to rotate. The crankshaft enters the drying mechanism 1. The hot air discharged from the hot air blower 13 onto the surface of the crankshaft. The moisture and dirt on the crankshaft are carried away by the hot air and fall through the ventilation holes on the conveyor belt 22 into the return air guide shroud 15. The air is then discharged from the through groove at the bottom of the return air guide shroud 15. At the same time, the hot air discharged from the hot air blower 13 into the return air guide shroud 15. Guided by the curvature of the inner wall of the return air guide shroud 15, the hot air passes through the conveyor belt 22 from the bottom, dries the crankshaft from the bottom, and flows back to the top. Guided by the curvature of the inner wall of the isolation shroud 12, the hot air passes through the mounting bracket 11 and the isolation shroud 12. The air circulates in the space formed between the hood 12 and the return air guide hood 15. When the crankshaft passes through the recess formed by the two hollow transmission rollers 23 and a high-pressure gas transfer box 14, the contact surface between the crankshaft and the conveyor belt 22 is fully exposed. Hot air from the bottom up dries the contact surface of the crankshaft. When the contact surface between the conveyor belt 22 and the crankshaft passes through the recess formed by the guide roller 24, the cleaning scraper 263 scrapes away the water stains and dirt remaining on the contact surface of the conveyor belt 22. At the same time, the high-pressure gas transfer box 14 injects high-pressure gas into the connecting pipe 27. The high-pressure gas enters the high-pressure air pipe 261 through the connecting pipe 27 and is discharged from the cleaning nozzle 262 through the distribution of the high-pressure air pipe 261. The gas impacts and cleans the dirt remaining in the vent holes on the surface of the conveyor belt 22. After the contact surface of the conveyor belt 22 is cleaned, it contacts the crankshaft again, driving the crankshaft through the drying mechanism 1 and being discharged from the outlet, thus completing the drying of the parts.
