[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] As attached Figure 1 and attached Figure 2 As shown, a coating device for applying wear-resistant plastic lining to a power plant boiler includes a base 1, a central shaft 2 rotatably mounted at the center of the upper side of the base 1, a motor 3 connected to the central shaft 2 installed inside the base 1, a horizontal plate 4 fixedly mounted on the lower outer side of the central shaft 2, a threaded shaft 5 rotatably mounted on the upper side of the horizontal plate 4, a second motor 6 connected to the threaded shaft 5 installed on the lower side of the horizontal plate 4, and a controller 21 connected to the motor 3 and the second motor 6 installed inside the base 1.

[0025] A threaded tube 8 is sleeved on the outside of the threaded shaft 5, and a sleeve 9 connected to the threaded tube 8 is slidably sleeved on the outside of the central shaft 2. Support frames 11 are respectively installed on the upper and lower outer sides of the sleeve 9. A vertical plate 12 is connected between the other sides of the two sets of support frames 11. An L-shaped coating plate 15 is provided on one side of the vertical plate 12. The L-shaped coating plate 15 is laterally movable and connected to the vertical plate 12.

[0026] With the above structure, the connecting wire of motor 26 passes through the interior of the central shaft 2 and is rotatably connected to the connecting wire of the controller 21. The controller 21 is equipped with an infrared receiver to facilitate connection with external control equipment, and the external control equipment sends signals to the controller 21.

[0027] The coating equipment is placed inside the power plant boiler. After leveling the base 1, the position of the central shaft 2 is adjusted to coincide with the axis of the cylindrical power plant boiler lining. The position of the L-shaped coating plate 15 is adjusted laterally so that it is close to the power plant boiler lining. Material is fed onto the power plant boiler lining using the existing feeding device. The controller 21 starts motor 3 and motor 6. Motor 3 drives the central shaft 2 to rotate. The horizontal plate 4 drives motor 6 and threaded shaft 5 to rotate around the central shaft 2. The threaded shaft 5 drives the sleeve 9 to rotate outside the central shaft 2, thereby rotating the L-shaped coating plate 15. The L-shaped coating plate 15 applies wear-resistant plastic coating to the power plant boiler lining. Motor 6 drives the threaded shaft 5 to rotate. The threaded shaft 5 drives the threaded tube 8 to move up and down. The threaded tube 8 drives the sleeve 9 to move up and down outside the central shaft 2, thereby adjusting the height of the L-shaped coating plate 15. The specific structure is as follows:

[0028] Combined with appendix Figure 1 and attached Figure 3 As shown, a threaded shaft 13 passes through the center of the vertical plate 12. An installation plate 14 is rotatably mounted on the end of the threaded shaft 13 away from the central axis 2. The L-shaped coating plate 15 is mounted on the installation plate 14 with multiple sets of bolts. The middle of the vertical plate 12 is provided with a threaded hole 17 for the threaded shaft 13 to pass through. Limiting rods 16 are respectively installed on the upper and lower parts of the installation plate 14. The upper and lower parts of the vertical plate 12 are respectively provided with through holes 18 for the limiting rods 16 to slide through.

[0029] With the above structure, rotating the threaded shaft 13 causes it to rotate inside the threaded hole 17, allowing it to move laterally. The threaded shaft 13 then pushes the L-shaped applicator 15 to adjust its position. When the L-shaped applicator 15 moves laterally, it slides inside the through hole 18 via the limiting rod 16, which limits the mounting plate 14 and the L-shaped applicator 15, preventing the L-shaped applicator 15 from rotating with the threaded shaft 13.

[0030] Combined with appendix Figure 1 As shown, a connecting plate 10 is provided between the outer wall of the threaded tube 8 and the outer wall of the sleeve 9. A limiting plate 7 is fixedly installed on the top of the central shaft 2, and the top of the threaded shaft 5 is rotatably connected to the lower side of the limiting plate 7.

[0031] With the above structure, the threaded tube 8 and the sleeve 9 are fixedly connected by the connecting plate 10, which makes it easy for the threaded tube 8 to drive the sleeve 9 to rotate outside the central shaft 2. The limiting plate 7 cooperates with the horizontal plate 4, and when the central shaft 2 rotates, it drives the threaded shaft 5 to rotate around the central shaft 2.

[0032] Example 2

[0033] Based on Example 1, please refer to the appendix. Figure 4The L-shaped coating plate 15 has an arc-shaped side wall away from the central axis 2. Baffles 19 are installed on the upper and lower sides of the L-shaped coating plate 15. The side wall of the baffle 19 away from the L-shaped coating plate 15 has an arc-shaped structure. The lower set of baffles 19 has an inclined structure. Specifically, the height of the side of the baffle 19 closer to the central axis 2 is lower than the height of the other side. A discharge port 20 is provided at the lower part of the side wall of the L-shaped coating plate 15 closer to the central axis 2.

[0034] With the structure described in Embodiment 2, when the wear-resistant plastic is applied to the inner lining of the power plant boiler using the L-shaped coating plate 15, excess material enters between the L-shaped coating plate 15 and the two sets of baffles 19. The collected material is then discharged and collected at the discharge port 20 by the lower inclined baffle 19, preventing excess material from falling along the inner wall of the power plant boiler, sticking to the inner wall of the power plant boiler and solidifying, thus affecting the subsequent application of the wear-resistant plastic.
