[0031] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0032] As Figures 1 to 8As shown in the figure, a spray painting device for a reactor shell of the present invention includes: a spray gun main body 10, a paint tank 20, and a chamber 30. The chamber 30 is opened inside the spray gun main body 10. The paint tank 20 is arranged on the top of the spray gun main body 10, and paint is contained inside the paint tank 20. It further includes: a needle valve 31, a driving component, a moving block 40, a water inlet 50, and a rotary cutting component. The needle valve 31 is arranged along the length direction of the chamber 30, and the needle valve 31 is used to control the opening and closing of the chamber 30. The driving component is arranged inside one side of the chamber 30, and the driving component can drive the needle valve 31 to rotate. The water inlet 50 is arranged at the bottom of the spray gun main body 10, and the water inlet 50 can be connected to a water pipe to let water flow through to wash the paint inside the chamber 30. The moving block 40 is slidably arranged inside the chamber 30, and the moving block 40 is used to push and scrape the residual paint on the inner wall of the chamber 30. The rotary cutting component is arranged on the outer peripheral surface of the needle valve 31, and the rotary cutting component can rotate and move along the axial direction of the needle valve 31 so as to cut the dried paint, improve the cleaning efficiency of the dried paint, and the rotary cutting component can be connected to or separated from the moving block 40. When connected, the moving block 40 can clean the inner wall, and when separated, the rotary cutting component can cut the dried paint.

[0033] After the spray painting of the reactor shell is completed, when immediately flushing the chamber 30, at this time the paint inside the chamber 30 has not dried yet. Manually connect the water pipe to the water inlet 50, and wash the paint inside the chamber 30 through the water flow. After the flushing is completed, the driving component drives the needle valve 31 to rotate. At this time, the needle valve 31 is connected to the moving block 40. The rotation of the needle valve 31 drives the rotary cutting component and the moving block 40 to move simultaneously, so that the moving block 40 scrapes the residual paint on the chamber 30, pushes the residual paint to the nozzle, and then flushes it again through the water flow, thereby improving the cleaning efficiency and effect of cleaning the chamber 30. When forgetting to flush the paint on the inner wall of the chamber 30 in time after the spray painting is completed, the paint has dried on the inner wall of the chamber 30. At this time, the needle valve 31 is separated from the moving block 40. The driving component drives the needle valve 31 to rotate. The rotation of the needle valve 31 drives the rotary cutting component to move along the length direction of the chamber 30, so as to cut the dried paint. After the rotary cutting is completed, then connect the needle valve 31 to the moving block 40, and then scrape the paint on the chamber 30 through the moving block 40. Finally, let water in through the water inlet 50 for flushing, which is convenient for cleaning the paint dried in the chamber 30, improving the cleaning efficiency and effect, and reducing the workload of manual cleaning.

[0034] As Figures 1 to 2As shown, the end face of the chamber 30 is circular. One end of the paint can 20 is provided with a liquid inlet pipe 21. The liquid inlet pipe 21 is inclined and communicates with the chamber 30. The paint in the paint can 20 can enter the interior of the chamber 30 through the liquid inlet pipe 21. The left end of the spray gun body 10 is provided with a nozzle 14. The nozzle 14 is connected to the spray gun body 10 by a threaded manner. It should be noted that when flushing or scraping the paint, first the nozzle 14 needs to be removed and the needle valve 31 is in the open state.

[0035] As Figures 1 to 6 shown, the left end of the needle valve 31 is conical. The outer peripheral surface of the needle valve 31 is provided with threads. The needle valve 31 is in threaded cooperation with the rotary cutting assembly. A fixing plate 45 is provided at a position near the right end in the chamber 30. And the right end of the needle valve 31 penetrates through the axial center position of the fixing plate 45. The fixing plate 45 plays a supporting role for the needle valve 31. A gear 61 is provided on the outer peripheral surface of the needle valve 31. The driving assembly can drive the gear 61 to rotate, so that the needle valve 31 can rotate. A guide rod 32 is arranged inside the chamber 30. The guide rod 32 penetrates through the rotary cutting assembly to make the movement of the rotary cutting assembly more stable.

[0036] As Figures 3 to 7 shown, the rotary cutting assembly includes: a rotary cutting block 60, a rotary sleeve 69, rotary cutting slices 62 and teeth 63. The rotary cutting block 60 is arranged on the outer peripheral surface of the needle valve 31. Threaded holes 64 and guide holes 65 are formed on the end face of the rotary cutting block 60. And the needle valve 31 penetrates through the threaded hole 64 and is in threaded cooperation with the rotary cutting block 60. And the guide rod 32 penetrates through the guide hole 65. The rotary sleeve 69 is rotatably sleeved on the outer peripheral surface of the rotary cutting block 60. A plurality of rotary cutting slices 62 are evenly spaced on the outer peripheral surface of the rotary sleeve 69. The rotary cutting slices 62 are used for cutting the dried paint on the chamber 30. Teeth 63 are arranged on the inner ring surface of the rotary sleeve 69. A motor two 70 is arranged inside the rotary cutting block 60. The output end of the motor two 70 is provided with a gear two 71. And the gear two 71 meshes with the teeth 63. A cover plate 68 is arranged on the end face of the rotary sleeve 69.

[0037] The driving component includes: a first motor 46, a rotating shaft 47, and a transmission gear 48. The first motor 46 is arranged on the right end side wall of the chamber 30. The rotating shaft 47 is arranged at the output end of the first motor 46. The transmission gear 48 is arranged at one end of the rotating shaft 47, and the transmission gear 48 meshes with the gear 61. When scraping or rotary cutting the paint, the first motor 46 can drive the rotating shaft 47 to rotate. The rotation of the rotating shaft 47 drives the transmission gear 48 to rotate. Since the transmission gear 48 meshes with the gear 61, the rotation of the transmission gear 48 drives the gear 61 to rotate. The rotation of the gear 61 drives the needle valve 31 to rotate. The rotation of the needle valve 31 drives the rotary cutting block 60 to move from right to left along the axial direction of the needle valve 31. The movement of the rotary cutting block 60 drives the rotary sleeve 69 and the rotary cutting piece 62 to move. At the same time, the second motor 70 can drive the second gear 71 to rotate. Since the second gear 71 meshes with the tooth 63, the rotation of the second gear 71 drives the rotary sleeve 69 and the rotary cutting piece 62 to rotate, so that the rotary sleeve 69 and the rotary cutting piece 62 perform rotary cutting on the paint dried on the chamber 30, thereby improving the efficiency of cutting the dried paint. At the same time, during the operation, the water inlet 50 is always connected to the water pump to intermittently flush the chamber 30, so that the cut paint is flushed towards the outlet, thereby improving the cutting effect and avoiding the cut paint being located on the right side of the rotary cutting component, and avoiding interference when the rotary cutting component is connected to the moving block 40.

[0038] As Figures 1 to 7 shown, the moving block 40 is provided with a placement cavity 90, and the rotary cutting component can be received inside the placement cavity 90. An insertion strip 66 is arranged on the outer wall of one end of the rotary cutting block 60. A first dovetail groove 67 is opened on the insertion strip 66. A slot 80 is opened on the placement cavity 90, and the insertion strip 66 can be inserted into the slot 80. A second dovetail groove 81 is opened in the slot 80. A through hole 82 is opened at the center of the moving block 40, and the needle valve 31 and the guide rod 32 penetrate through the through hole 82. When the rotary cutting component is connected to the moving block 40, first, the rotary cutting component is received inside the placement cavity 90, and the insertion strip 66 is inserted into the slot 80 so that the first dovetail groove 67 and the second dovetail groove 81 are abutted against each other. Subsequently, the limiting dovetail block 91 is manually inserted into the first dovetail groove 67 and the second dovetail groove 81 from the outside, so that the rotary cutting component is connected to the moving block 40, thereby enabling the rotary cutting component to pull the moving block 40 to move, and enabling the moving block 40 to scrape the paint on the inner wall of the chamber 30.

[0039] As Figures 1 to 7As shown, a handle 11 is provided on the outer wall of the spray gun body 10, an air inlet 12 is provided on the handle 11, a trigger 13 is provided on the bottom wall of the spray gun body 10, a pull rod 33 is provided inside the spray gun body 10, and the trigger 13 is in transmission cooperation with the pull rod 33.
