Technical Field
[0001] This utility model relates to the field of heat treatment technology, and more specifically, to a drying device for heat-treated parts. Background Technology
[0002] In modern industrial manufacturing, heat treatment of parts is an indispensable part of the processing flow. Heat treatment can not only improve the mechanical properties of materials, such as hardness, wear resistance, and toughness, but also eliminate residual stress inside the material, improving the stability and service life of parts. However, heat-treated parts often contain high levels of moisture and residual liquid. If this moisture and liquid are not removed in time, it will not only affect the subsequent processing and use of the parts, but may also adversely affect the operation of production equipment. Traditional parts drying methods mostly use hot air drying. However, since the air inside the drying chamber is often blown from both sides to the middle, the distribution of hot air is uneven, which often results in uneven drying of the surface and interior of the parts, and even local overheating or scorching, seriously affecting the quality and performance of the parts. Therefore, we propose a drying device for parts after heat treatment to solve the above problems. Utility Model Content

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0028] like Figures 4 to 10As shown, in another embodiment of this utility model, the auxiliary mechanism 5 includes a first air guide box 501 and a second air guide box 502. The first air guide box 501 is installed at the lower end of the interior of the drying chamber 3, located inside the conveyor belt 4, and is in contact with the upper end of the interior of the conveyor belt 4. The second air guide box 502 is installed at the upper end of the interior of the drying chamber 3, and is vertically parallel to the conveyor belt 4. A plurality of second exhaust troughs 505 are provided through the upper end of the interior of the first air guide box 501, and a first exhaust trough 503 is provided through the lower end of the interior of the second air guide box 502. A plurality of guide tubes are movably installed inside the first exhaust trough 503. A guide plate 504 has a rotating shaft 506 fixedly installed inside it. The rotating shaft 506 is movably installed inside the first exhaust duct 503. A groove 510 is provided on one side of the upper end of the drying chamber 3. A movable block 508 is movably installed inside the groove 510. Several teeth 509 are installed at the lower end of the movable block 508. Gears 507 are installed on the outer side of the shaft of the rotating shaft 506 at the lower end of the movable block 508. The gears 507 and teeth 509 are meshed. A fixed rod 511 is fixedly installed inside the groove 510. The rod of the fixed rod 511 is movably installed inside the movable block 508. The two ends of the fixed rod 511 are... Springs 515 are fitted onto the rod body, and the springs 515 are in contact with the movable block 508 and the groove 510. A drive shaft 512 is movably installed inside the groove 510. A pusher frame 513 is installed on the outside of the rod body inside the groove 510. An auxiliary rod 514 is installed on the upper end of the movable block 508. One end of the pusher frame 513 is movably installed on the upper end of the movable block 508 and is in contact with the auxiliary rod 514. The upper end of the drive shaft 512 is movably installed inside the air collection box 516. The air collection box 516 is installed on the upper surface of the box body 1 and on the side close to the drive shaft 512. The drive shaft 512 is located inside the air collection box 516. Several fan blades 517 are installed on the outer side of the rod body. A connecting pipe 518 is installed between one end of the air collecting box 516 and the second air guide box 502. A diversion pipe 519 is installed on the rear side of the box body 1. The upper end of the diversion pipe 519 is installed inside the air collecting box 516, and the lower end of the diversion pipe 519 is installed inside the first air guide box 501. A suction fan 521 is installed on the upper rear side of the box body 1. A second connecting pipe 520 is installed at the exhaust port of the suction fan 521. The second connecting pipe 520 is connected to the diversion pipe 519. An air guide hole 522 is provided through the rear end of the drying chamber 3. The air guide hole 522 is connected to the suction fan 521.
[0029] The drying fan 2 blows high-temperature air into the drying chamber 3. After the high-temperature air gradually fills the drying chamber 3, the suction fan 521 draws in the excess high-temperature air from the drying chamber 3 through the air guide hole 522. The high-temperature air then enters the split pipe 519 through the suction fan 521. The air entering the split pipe 519 then enters the air collection box 516 and the first air guide box 501 through the upper and lower ends of the split pipe 519. The air entering the air collection box 516 first blows the fan blade 517 to drive the drive shaft 512 to rotate. Then, it enters the second air guide box 502 through the first connecting pipe 518. The air entering the first air guide box 501 and the second air guide box 502 can then be blown relative to each other through the second exhaust duct 505 and the first exhaust duct 503, so that the airflow inside the drying chamber 3 flows in multiple directions, making the airflow more even inside the drying chamber 3.
[0030] Then, when the gas blows the fan blades 517 and drive shaft 512 to rotate, the drive shaft 512 drives the push frame 513 to continuously push the movable block 508 to one side via the auxiliary rod 514, causing the movable block 508 to compress the spring 515 along the fixed rod 511 and simultaneously stretch the other spring 515. Then, the movable block 508, through the engagement of the teeth 509 and gear 507, controls the rotating shaft 506 to rotate the guide plate 504 to one side, causing the guide plate 504 to tilt to guide the airflow. Then, when the push frame 513 and auxiliary rod 514 separate, the springs 515 will respectively exert pressure on the movable block 508. 08 is pushed and pulled to reset the movable block 508 in the opposite direction. At this time, the movable block 508, through the cooperation of the teeth 509 and the gear 507, controls the rotating shaft 506 and the guide plate 504 to rotate in the opposite direction. Thus, the push frame 513 continuously pushes the auxiliary rod 514 and the movable block 508 to move. After the push frame 513 and the auxiliary rod 514 separate, the spring 515 pushes the movable block 508 to reset. The movable block 508 continuously controls the guide plate 504 to adjust its angle inside the first exhaust duct 503 through the teeth 509 and the gear 507, further guiding the airflow to blow into the interior of the drying chamber 3 more evenly.
[0031] Then the user can place the raw material on the surface of the conveyor belt 4, and the conveyor belt 4 will carry the raw material into the drying chamber 3. Then the hot air inside the drying chamber 3 will evenly dry the raw material at the contact point. At the same time, the No. 1 air guide box 501 is used to support the upper end of the conveyor belt 4, thereby preventing the conveyor belt 4 from sinking due to the excessive weight of the raw material and improving the stability of the raw material drying process.
[0032] The surface of the conveyor belt 4 is a mesh chain, which allows the gas inside the second exhaust duct 505 to come into contact with the raw material when it blows upward, thus avoiding the situation where the lower end of the raw material cannot come into contact with the hot air, resulting in uneven drying.
[0033] The working principle of the drying device for heat-treated parts:
[0034] In operation, the drying fan 2 first blows high-temperature air into the drying chamber 3. After the high-temperature air gradually fills the drying chamber 3, the suction fan 521 draws in excess high-temperature air through the air guide hole 522, allowing the air to enter the distribution pipe 519. The air entering the distribution pipe 519 then flows through its upper and lower ends into the air collection box 516 and the first air guide box 501. The air entering the air collection box 516 first blows the fan blades 517, causing the drive shaft 512 to rotate. Then, the air enters the interior of the second air guide box 502 through the first connecting pipe 518. The air entering the first air guide box 501 and the second air guide box 502 can then be blown relative to each other through the second exhaust duct 505 and the first exhaust duct 503, so that the airflow inside the drying chamber 3 flows in multiple directions, making the airflow more evenly inside the drying chamber 3. Then, the user can place the raw material on the surface of the conveyor belt 4, and the conveyor belt 4 will carry the raw material into the interior of the drying chamber 3. Then, the hot air inside the drying chamber 3 can evenly dry the raw material at the contact point.
[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
