Detailed Implementation
[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] Please see Figures 1-3 This utility model provides a technical solution: a spraying device for anti-corrosion processing of electric heating tubes, including a spraying frame 1, a U-shaped electric heating tube body 9, and a bent tube 16. A paint shield 2 is installed at the rear end of the spraying frame 1. An electric push rod 3 is longitudinally installed at the upper end of the inside of the spraying frame 1. A moving plate 4 is horizontally installed at the movable end of the electric push rod 3. Multiple fixed shafts 5 are installed at the lower end of the moving plate 4. The other ends of the multiple fixed shafts 5 are respectively installed on multiple first bearings 6. Rotating plates 7 are horizontally fixed on the outside of the multiple first bearings 6. Two limiting sleeves 8 are fixed at the lower end of the multiple rotating plates 7. Multiple U-shaped electric heating tube bodies 9 are provided. The lower end of the spraying frame 1... Multiple second bearings 13 are installed at the end, and a rotating shaft 12 is installed through each of the multiple second bearings 13. A groove block 11 is horizontally fixed at the upper end of each of the multiple rotating shafts 12. An arc-shaped sponge 10 is provided in the groove at the upper end of each of the multiple groove blocks 11. A spur gear 15 is installed at the lower end of each of the multiple rotating shafts 12. Multiple bent tubes 16 are provided. The multiple bent tubes 16 are longitudinally fixed at the front end of the spray frame 1. Sliding sleeves 17 are slidably fitted on the outside of each of the multiple bent tubes 16. A spray head 18 is provided on the right side of each of the multiple sliding sleeves 17. This design solves the problem that the original device can only spray a single electric heating tube each time it is used, and the efficiency needs to be improved.
[0019] In the first embodiment of this utility model: the upper ends of multiple U-shaped heating tube bodies 9 are respectively fitted inside multiple limiting sleeves 8, and the upper ends of the multiple U-shaped heating tube bodies 9 can be limited by the added multiple limiting sleeves 8. The lower ends of the multiple U-shaped heating tube bodies 9 are respectively inserted into multiple arc-shaped sponges 10, and the lower U-shaped ends of the multiple U-shaped heating tube bodies 9 can be limited by the added multiple arc-shaped sponges 10. At the same time, the multiple arc-shaped sponges 10 are impregnated with anti-corrosion spray paint, so that they can adhere to the lower U-shaped ends of the multiple U-shaped heating tube bodies 9.
[0020] Multiple adjacent spur gears 15 mesh with each other, so that when one spur gear 15 rotates, it drives the others to rotate. Multiple spray heads 18 are positioned opposite multiple U-shaped heating tube bodies 9. When connected to an external spray pipe, these spray heads 18 can perform spraying operations on the multiple U-shaped heating tube bodies 9. A low-speed motor 14 is installed at the lower end of the left spur gear 15, which drives the left spur gear 15 to rotate.
[0021] As a second embodiment of this utility model: When spraying each U-shaped heating tube body 9, firstly, the lower U-shaped end of each U-shaped heating tube body 9 is inserted into multiple arc-shaped sponges 10. Then, anti-corrosion spray paint is immersed in the multiple arc-shaped sponges 10. Then, the movable end of the electric push rod 3 is controlled to move downward, which can then drive each limiting sleeve 8 to move downward through the moving plate 4, fixed shaft 5, first bearing 6, and rotating plate 7 until each limiting sleeve 8 is fitted onto the upper end of each U-shaped heating tube body 9. Then, multiple spray heads 18 are connected to the external spray pipe, and the low-speed motor 14 is started. The low-speed motor 14 can drive the left spur gear 15 to rotate, and the adjacent spur gear 1... 5 will also be driven to rotate in the opposite direction, which will in turn drive the other spur gears 15 to rotate, which will cause multiple rotating shafts 12 and multiple inner rings of second bearings 13 to rotate. When multiple rotating shafts 12 are in operation, multiple groove blocks 11 will be rotated. The rotation of multiple arc-shaped sponges 10 will drive multiple U-shaped electric heating tube bodies 9 to rotate at low speed, which will cause multiple limiting sleeves 8, multiple rotating plates 7 and multiple outer rings of first bearings 6 to rotate as well. Then, each sliding sleeve 17 is moved up and down, and each spray head 18 is activated, so that the surface of the multiple rotating U-shaped electric heating tube bodies 9 can be sprayed. The set paint shield 2 can intercept the sprayed paint that has been sprayed too far.
