[0023] The present invention will be further described in detail below with reference to the accompanying drawings.
[0024] like Figure 1 As shown, an odor purification device for automatic painting of steel pipes includes a steel pipe 1, a positioning mechanism 2, a ventilation mechanism 3, a painting assembly 4, a sealing sleeve 5, and a traveling mechanism 6.
[0025] like Figure 1 As shown, the steel pipe 1 is open at both ends. The positioning mechanism 2 is located at the pipe opening at one end of the steel pipe 1. The ventilation mechanism 3 passes through and is slidably connected to the positioning mechanism 2, and extends into the steel pipe 1. The painting assembly 4 is located at the front end of the ventilation mechanism 3 and inside the steel pipe 1, and is used to perform painting operations on the inner wall of the steel pipe 1.
[0026] like Figure 1 As shown, the sealing sleeve 5 is located at the front end of the painting assembly 4, and its outer wall is in contact with the inner wall of the steel pipe 1, which is used to seal the steel pipe 1 so that the painting assembly 4 operates in a closed space. The traveling mechanism 6 is located at the front end of the sealing sleeve 5 and is used to control the sliding of the painting assembly 4.
[0027] When painting is required on the inner wall of steel pipe 1, the ventilation mechanism 3, painting assembly 4, sealing sleeve 5, and traveling mechanism 6 are inserted into steel pipe 1, and then fixed by positioning mechanism 2 to seal the pipe opening. Simultaneously, with the cooperation of sealing sleeve 5, a sealed working space is formed between positioning mechanism 2 and sealing sleeve 5, and painting assembly 4 is located within this sealed space.
[0028] Then, the painting assembly 4 is activated to paint the inner wall of the steel pipe 1. At the same time, the traveling mechanism 6 is used to control the air exchange mechanism 3, the painting assembly 4 and the sealing sleeve 5 to slide inside the steel pipe 1, so that the painting assembly 4 can achieve all-round painting of the inner wall of the steel pipe 1.
[0029] Furthermore, during the painting process, a sealed working space is always formed between the positioning mechanism 2 and the sealing sleeve 5, which reduces the leakage of odorous paint fumes from the steel pipe 1. During the painting operation, the ventilation mechanism 3 can also be used to extract the odorous gases from the steel pipe 1 and purify them outside, which can not only maintain the air pressure balance inside the steel pipe 1, but also prevent the spread of harmful gases, avoid damage to the health of operators, and maintain a clean environment.
[0030] During use, the sealing sleeve 5 is designed to be detachable. When the inner diameter of the steel pipe 1 is too large or too small, a sealing sleeve 5 of different sizes can be replaced for sealing. The principle for using the size of the sealing sleeve 5 is that it can be pulled along the steel pipe 1 and can seal the inner wall of the steel pipe 1.
[0031] like Figure 1 As shown, the positioning mechanism 2 includes a positioning disc 21 and multiple fixing bolts 22. The positioning disc 21 is a cover-shaped structure and is used to fasten to the pipe opening of the steel pipe 1. The fixing bolts 22 are distributed around the positioning disc 21 and are used to press the outer wall of the steel pipe 1.
[0032] When it is necessary to seal the opening of the steel pipe 1 and limit and fix the entire device, by rotating the fixing bolt 22, the bottom of the fixing bolt 22 can clamp the side wall of the steel pipe 1, and the end of the steel pipe 1 can be attached to the bottom wall of the positioning plate 21. Tighten the fixing bolt 22 to fix the position of the positioning plate 21, and seal one end of the steel pipe 1 to prevent paint odor from escaping.
[0033] like Figure 1 , Figure 2 As shown, the ventilation mechanism 3 includes a main pipe 31, an inlet pipe 32, an outlet pipe 33, and a vent 34. The main pipe 31 passes through the center of the positioning plate 21. One end of the inlet pipe 32 and the outlet pipe 33 are located inside the main pipe 31, and the other end is located outside the main pipe 31. The inlet pipe 32 is connected to an external air pump 321, and the outlet pipe 33 is connected to an external suction pump 331. The vent 34 passes through both sides of the main pipe 31 and is connected to the inlet pipe 32 and the outlet pipe 33, respectively.
[0034] When spray painting is being performed, the air intake pump 321 can be activated to inject clean air into the steel pipe 1. Air containing air-purifying and freshening components can also be injected into the steel pipe 1 to neutralize the odor produced by the paint inside, thus achieving odor purification. Then, the exhaust pump 331 is activated to extract a portion of the odorous gas from the steel pipe 1 for external purification, while simultaneously maintaining the air pressure balance inside the steel pipe 1.
[0035] like Figure 1 As shown, the painting assembly 4 includes a motor 41, a spray pipe 42, and a connecting sleeve 43. The motor 41 is fixed to the front end of the main pipe 31, and an electric wire 8 runs through the main pipe 31, providing power to the motor 41. The output end of the motor 41 is connected to the spray pipe 42, and the spray pipe 42 has nozzles around its perimeter.
[0036] like Figure 1 As shown, the connecting sleeve 43 is threaded to the sealing sleeve 5 and rotatably connected to the end of the nozzle 42 away from the motor 41. The sealing sleeve 5 and the traveling mechanism 6 are provided with a paint channel 7 that communicates with the nozzle 42.
[0037] When spraying paint, the motor 41 is started, and the motor 41 drives the spray pipe 42 to rotate 360°. At this time, the nozzle on the spray pipe 42 sprays paint onto the inner wall of the steel pipe 1, so as to achieve uniform spraying of the inner wall of the steel pipe 1, ensure that the paint layer thickness of the inner wall of the steel pipe 1 is consistent, and ensure the quality of spraying.
[0038] like Figure 1 , Figure 3 As shown, the traveling mechanism 6 includes a push rod 61, a slide 62, a sliding tube 63, a tube clamp 64, a support rod 65, a pulley 67, and a tie rod 66.
[0039] like Figure 1 , Figure 3 As shown, the slide groove 62 is arranged along the axial direction of the push rod 61 and is distributed in a ring array on the outer wall of the push rod 61. The sliding tube 63 is threaded to the sealing sleeve 5 and slidably connected to the outer wall of the push rod 61. A slider that is slidably connected to the slide groove 62 is provided on the sliding tube 63.
[0040] like Figure 1 , Figure 3 As shown, the outer wall of the sliding tube 63 has a through crack. The tube clamp 64 is disposed on the outer wall of the sliding tube 63 and is used to clamp the sliding tube 63, so that the sliding tube 63 presses against the outer wall of the push rod 61. The outer wall of the sliding tube 63 is provided with a push handle 631 to facilitate pushing the sliding tube 63 to slide.
[0041] like Figure 1 , Figure 3As shown, one end of the support rod 65 is rotatably connected to the outer end of the sliding tube 63, and the pulley 67 is disposed at the end of the support rod 65 and is used to abut against the inner wall of the steel pipe 1. One end of the diagonal tie rod 66 is rotatably connected to the end of the support rod 65 near the pulley 67, and the other end is rotatably connected to the push rod 61.
[0042] When installing the entire device, first open the pipe clamp 64. Then, hold the push rod 61 with one hand and pull the push handle 631 with the other hand to move the sliding tube 63 along the axial direction of the push rod 61, so that the push rod 61 extends into the sliding tube 63. At the same time, with the cooperation of the diagonal tie rod 66, the multiple support rods 65 open outward and drive the pulley 67 to gradually approach the inner wall of the steel pipe 1. After the pulley 67 touches the inner wall of the steel pipe 1, lock the pipe clamp 64 to fix the sliding tube 63.
[0043] Subsequently, during the painting process, the push rod 61 can be pulled to slide outwards from the steel pipe 1. The push rod 61 drives the sealing sleeve 5, the ventilation mechanism 3, and the painting assembly 4 to move together along the inner wall of the pipe, completing the automatic painting and odor purification process.
[0044] Furthermore, during operation, multiple pulleys 67 support the inner wall of the steel pipe 1, centered the ventilation mechanism 3 and the painting assembly 4. This allows the painting assembly 4 to spray the inner wall of the steel pipe 1 evenly, while the ventilation mechanism 3 can evenly purify the air inside the steel pipe 1, ensuring the purification effect.
[0045] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
