[0024] Please refer to Figures 1-5 , this embodiment provides a technical solution: A hot air blower housing for steel pipe surface enamel coating processing, including a hot air blower housing 1 and a door lock mechanism 3;

[0025] Hot air blower housing 1: A maintenance door 2 is hinged on its front side. It also includes a single-chip microcomputer 5 which is arranged at the front end of the upper surface of the hot air blower housing 1. The input end of the single-chip microcomputer 5 is electrically connected to an external power supply. It also includes a mounting bracket 7 which is fixedly connected between the upper and lower inner walls in the middle of the hot air blower housing 1. Electric heating wires 8 are respectively arranged on the left and right sides of the mounting bracket 7. The input end of the electric heating wire 8 is electrically connected to the output end of the single-chip microcomputer 5. It also includes a blower 4 which is installed on the right side of the hot air blower housing 1 by bolts. The air outlet of the hot air blower housing 1 extends to the inside of the hot air blower housing 1. The input end of the blower 4 is electrically connected to the output end of the single-chip microcomputer 5. It also includes an air outlet pipe 6 which is fixedly connected to the air outlet at the left side of the hot air blower housing 1. By controlling the operation of the electric heating wire 8 through the single-chip microcomputer 5, the electric heating wire 8 transfers heat to the inside of the hot air blower housing 1. Then, by regulating the operation of the blower 4 through the single-chip microcomputer 5, the blower 4 sucks in external air and blows the air onto the electric heating wire 8. In this way, the air flow heated by the electric heating wire 8 is gradually heated to reach the required temperature and is blown onto the enamel coating applied on the surface of the steel pipe through the air outlet pipe 6, thus achieving the purpose of uniformly coating the surface of the steel pipe;

[0026] Door lock mechanism 3: It includes a locking plate 31, a rotating shaft 32, a locking block 34 and a locking groove 35. The rotating shaft 32 is rotatably connected to the right end of the front side of the maintenance door 2. The rear end of the rotating shaft 32 is fixedly connected with a locking plate 31. The locking plate 31 is located inside the hot air blower housing 1. The locking block 34 is fixedly connected to the right end of the inner wall of the front side of the hot air blower housing 1. A locking groove 35 is formed on the upper surface of the locking block 34. The locking groove 35 is fitted and installed with the locking plate 31. The door lock mechanism 3 further includes a spring 36, a fixed block 37, an arc-shaped sliding column 38 and an arc-shaped sliding hole 39. The fixed block 37 is fixedly connected to the right end of the rear side of the maintenance door 2. An arc-shaped sliding hole 39 is formed inside the fixed block 37. The inner wall of the arc-shaped sliding hole 39 is slidably connected with an arc-shaped sliding column 38. The top end of the arc-shaped sliding column 38 is fixedly connected with the lower surface of the locking plate 31. A spring 36 is fixedly connected between the lower surface of the locking plate 31 and the right side surface of the fixed block 37. The spring 36 is sleeved on the outer surface of the arc-shaped sliding column 38. The door lock mechanism 3 further includes a door handle 33. The door handle 33 is fixedly connected to the front end of the rotating shaft 32. When it is necessary to clean, inspect, repair and adjust the hot air blower after long-term use, rotate the door handle 33. The door handle 33 will drive the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 drives the locking plate 31 to rotate. The rotation of the locking plate 31 will separate from the locking groove 35. At the same time, the arc-shaped sliding column 38 moves along the arc-shaped sliding hole 39 and stretches the spring 36. This process enables the maintenance door 2 to be freely opened, facilitating cleaning, inspection, repair and adjustment operations. In the state where the maintenance door is opened, it is possible to enter the interior of the hot air blower to perform the required cleaning, inspection, repair and adjustment work. When the cleaning, inspection, repair and adjustment work is completed, release the rotated door handle 33. Under the action of the spring 36, the locking plate 31 will rebound back into the locking groove 35, fixing the maintenance door 2 and ensuring that the maintenance door 2 is securely closed to restore the normal operating state of the hot air blower.

[0027] The working principle of a hot air blower housing for steel pipe surface enamel coating processing provided by the present utility model is as follows: First, the microcontroller 5 controls the operation of the electric heating wire 8, and the electric heating wire 8 transfers heat to the inside of the hot air blower housing 1. Then, the microcontroller 5 regulates the operation of the blower 4. The blower 4 sucks in external air and blows the air towards the electric heating wire 8. In this way, the air flow heated by the electric heating wire 8 is gradually heated and reaches the required temperature, and is blown onto the enamel coating applied to the surface of the steel pipe through the air outlet pipe 6, thereby achieving the purpose of uniformly coating the surface of the steel pipe. When cleaning, inspecting, repairing, and adjusting are required after long-term use of the hot air blower, rotate the door handle 33. The door handle 33 will drive the rotation shaft 32 to rotate. The rotation of the rotation shaft 32 drives the locking plate 31 to rotate. The rotation of the locking plate 31 will separate from the locking groove 35. At the same time, the arc-shaped sliding column 38 moves along the arc-shaped sliding hole 39 and stretches the spring 36. This process enables the maintenance door 2 to be freely opened, facilitating cleaning, inspection, repair, and adjustment operations. In the state where the maintenance door is opened, it is possible to enter the interior of the hot air blower to perform the required cleaning, inspection, repair, and adjustment work. When the cleaning, inspection, repair, and adjustment work is completed, release the rotated door handle 33. Under the action of the spring 36, the locking plate 31 will rebound back into the locking groove 35, fixing the maintenance door 2 and ensuring that the maintenance door 2 is securely closed to restore the normal operating state of the hot air blower.
