Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and in particular to a vertical storage tank inner wall coating spraying device. Background Technology

[0002] Spraying, generally referred to as spraying, is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets using pressure or centrifugal force, and then applies the coating to the surface of the object. Chinese utility model patent, authorized announcement number "CN216459552U", discloses an automatic spraying device for the inner wall of a storage tank. This automatic spraying device for the inner wall of a storage tank uses a motor to rotate the tank via a clamping platform. A hydraulic cylinder drives two nozzles to extend into the tank via a positioning plate. A power pump sprays paint onto the inner wall of the tank through the nozzles via a distribution box and two corrugated pipes. While the hydraulic cylinder drives the nozzles to move up and down, the tank rotates, thereby improving the uniformity of the spraying on the inner wall of the tank. Furthermore, the entire process requires no manual operation, thus improving spraying efficiency.

[0003] The above-mentioned technical solutions neglect the cleaning of the inner wall of the storage tank before spraying, or only use simple manual wiping. The internal space of vertical storage tanks is narrow and the environment is complex. Manual wiping is prone to incomplete cleaning in some areas, and the cleaning quality is greatly affected by the operator's operating skills and work attitude, making it difficult to ensure the consistency of the cleaning effect. This can easily reduce the adhesion of the coating. Over time, the coating is prone to problems such as peeling and blistering, thus reducing the spraying quality of the inner wall of the storage tank. Therefore, we propose a vertical storage tank inner wall coating spraying device. Utility Model Content

[0027] Please see Figure 1-5 This utility model provides a technical solution: a vertical storage tank inner wall coating spraying device, comprising:

[0028] A fixed base plate 1 is fixedly connected to a support frame 2 on its top. The support frame 2 has a movable structure inside, and a spraying structure is provided on the top of the fixed base plate 1.

The dust discharge box 6 is connected to the rotating pipe of the cleaning roller 22 through a pipe. The pipe on the dust discharge box 6 is rotatably connected to the rotating pipe of the cleaning roller 22.

[0031] The internal cleaning structure also includes a drive motor 19 and a belt 20. The drive motor 19 is fixedly installed on the side of the mounting frame 8 near the electric telescopic rod 21. The belt 20 is connected to the output end of the drive motor 19 and the bottom end of the cleaning roller 22. A collection box is slidably connected inside the ash discharge box 6.

[0032] The spraying structure includes a storage tank 14, a second electric lifting rod 15, a power pump 16, and a spray box 23. The storage tank 14 is fixedly connected to the top of the fixed base plate 1. The second electric lifting rod 15 is fixedly installed on the top of the fixed base plate 1. The spray box 23 is fixedly installed on the telescopic end of the second electric lifting rod 15. The power pump 16 is fixedly installed on the top of the storage tank 14. The suction end of the power pump 16 is connected to the inside of the storage tank 14. The discharge end of the power pump 16 is connected to the inside of the spray box 23 through a pipe. Two nozzles connected to the inside of the spray box 23 are fixedly connected to the outer surface of the spray box 23.

[0033] The moving structure includes two adjusting motors 4, two threaded rods 3, a moving platform 9, and a rotating frame 13. The two threaded rods 3 are rotatably connected inside the support frame 2. The two adjusting motors 4 are fixedly installed on one side of the support frame 2. The output ends of the two adjusting motors 4 rotatably extend into the interior of the support frame 2 and are fixedly connected to the corresponding threaded rods 3. The protrusions on both sides of the moving platform 9 are threaded onto the outer surface of the corresponding threaded rods 3. The rotating frame 13 is rotatably connected to the top of the moving platform 9. The rotating frame 13 is a combination of a "U"-shaped frame and an annular column.

[0034] The moving structure also includes two electric push rods 11, two clamping plates 10, a gear 12, a gear ring 17, and a rotating motor 18. The gear ring 17 is fixedly sleeved on the rotating column at the bottom of the rotating frame 13. The rotating motor 18 is fixedly installed inside the moving platform 9. The output end of the rotating motor 18 is fixedly connected to the gear 12. The gear 12 is meshed with the gear ring 17. The two electric push rods 11 are respectively fixedly installed on both sides of the rotating frame 13. The telescopic ends of the two electric push rods 11 slide into the interior of the rotating frame 13 and are fixedly connected to the corresponding clamping plates 10.

[0035] Furthermore, when using the device, the vertical storage tank is placed on the rotating frame 13, and the two electric push rods 11 are activated. The two electric push rods 11 will drive the corresponding clamping plates 10 to clamp the storage tank and fix its position. At this time, the storage tank is located above the first electric lifting rod 7. When cleaning the inside of the storage tank, the first electric lifting rod 7 is activated, which will raise the mounting frame 8 and the cleaning roller 22 into the inside of the storage tank. The drive motor 19 is activated, and the drive motor 19 drives the cleaning roller 22 to rotate through the belt 20. Since the cleaning roller 22 is rotatably connected to the pipe connecting the ash discharge box 6, the pipe is prevented from getting tangled. The electric telescopic rod 21 is activated by connecting an external power source. The electric telescopic rod 21 will move through the mounting frame 8. Move the cleaning roller 22 close to the inner wall of the storage tank so that the cleaning roller 22 can clean the inner wall of the storage tank. Then, start the rotating motor 18, and its output end drives the gear 12 to rotate. Through meshing with the gear ring 17, the rotating frame 13 drives the storage tank to rotate, so that the cleaning roller 22 can clean the inside of the storage tank evenly. The dust suction port on the outer surface of the cleaning roller 22 is close to the inner wall of the storage tank to collect dust and impurities. Start the exhaust fan 5 by connecting the external power supply. The exhaust fan 5 will draw the dust in the cleaning roller 22 into the dust discharge box 6 through the pipe, so that the cleaning roller 22 can suck up the cleaned dust through its multiple dust suction ports. After the inside of the storage tank is cleaned, the cleaning roller 22 will move downward and reset.

[0036] This activates two regulating motors 4, which drive the corresponding threaded rods 3 to rotate. The rotation of the two threaded rods 3 causes the moving platform 9 to move along the threaded rods 3, thus facilitating the movement of the storage tank above the second electric lifting rod 15. Subsequently, the second electric lifting rod 15 is activated, which raises the spray box 23 into the interior of the storage tank. The power pump 16 draws paint from the storage tank 14 and delivers it through pipelines to the spray box 23, where it is then sprayed out by two nozzles on the spray box 23. The rotating frame 13 rotates, thus facilitating uniform spraying of the inner wall of the storage tank.

[0037] This device is equipped with an internal cleaning structure. The cleaning roller 22 rotates under the drive of the drive motor 19. The dust suction port on the outer surface can fully fit the inner wall of the storage tank. With the powerful suction of the exhaust fan 5, it can penetrate into complex areas and thoroughly remove dust and impurities, further improving the coating quality of the inner wall of the storage tank.
