Description

Technical Field

[0001] This utility model relates to the technical field of pressure vessel production equipment, specifically to a pressure vessel protective coating spraying equipment. Background Technology

[0002] Pressure vessels, as sealed containers, have a wide range of applications and operate in complex environments. Therefore, after production, pressure vessels typically require a layer of anti-corrosion protective coating to be sprayed onto their surface to improve their corrosion resistance.

[0003] CN 214515421 U discloses a pressure vessel anti-corrosion coating spraying device, which includes a support rod with a vertical T-shaped groove on one side. A T-shaped block is slidably disposed within the T-shaped groove, and a spray head is held in place by the T-shaped block. A clamping mechanism is disposed on the side of the support rod with the T-shaped groove, including a primary turntable, multiple secondary turntables evenly distributed circumferentially on the top surface of the primary turntable, a clamping groove in the center of the secondary turntable, a vertical central rod at the center of the primary turntable, and multiple vertical sliding rods evenly distributed circumferentially on the central rod, the sliding rods being movable up and down; and a clamping head disposed at the top of the sliding rods. This device aims to achieve automated spraying operation, stable spraying quality, continuous spraying, and improved spraying efficiency. However, the following problems still exist: 1. During operation, the two arc-shaped rods of the clamping mechanism are clamped at the top of the pressure vessel. During the rotation of the pressure vessel, the arc-shaped rods form scratches on the surface of the pressure vessel; 2. There is a lot of dust overflow during the spraying process, which pollutes the working environment; 3. The top of the pressure vessel is an arc-shaped top. When the nozzle sprays this position, the distance is far from it, resulting in poor spraying effect. Utility Model Content

Compared with the prior art, it avoids damage to the pressure vessel, reduces pollution to the working environment, and improves the overall spraying effect on the pressure vessel.

[0020] like Figures 1-3 As shown, the pressure vessel protective coating spraying equipment includes a base plate 6, a pressure vessel support turntable 17, a clamping mechanism and a spraying mechanism standing on both sides of the pressure vessel support turntable 17.

[0021] The clamping mechanism includes a lifting cylinder 20, a horizontal support arm 19 located at the top of the telescopic rod of the lifting cylinder 20, a bearing 18 located at the end of the horizontal support arm 19, and a pressure block 21 fixedly connected to the inner ring surface of the bearing 18. The centerline of the pressure block 21 coincides with the centerline of the pressure vessel support turntable 17, and the lower surface of the pressure block 21 is an arc surface that mates with the top surface of the pressure vessel 16.

[0022] The spraying mechanism includes a longitudinal screw drive mechanism, a direct support 10 connected to the longitudinal screw drive mechanism, a horizontal electric telescopic rod 15 connected to the direct support 10, a small bracket 14 connected to the telescopic end of the horizontal electric telescopic rod 15, a nozzle 12 mounted on the small bracket 14, a laser rangefinder 13 located below and parallel to the nozzle 12, and a dust collection hood 11 located diagonally above the nozzle 12. The dust collection hood 11 is connected to the inlet of the exhaust fan 7 via a smoke exhaust pipe 9. The outlet pipe of the exhaust fan 7 extends to the factory's flue gas treatment pipe. The nozzle of the nozzle 12 points towards and is perpendicular to the center line of the pressure vessel support turntable 17. The smoke exhaust pipe 9 has a telescopic section 8.

[0023] In this embodiment, the direct support 10 consists of a vertical plate 1002 connected to the slider 2 of the longitudinal screw drive mechanism and a horizontal plate 1001 connected to the upper end of the vertical plate 1002. The fixing part of the horizontal electric telescopic rod 15 is connected and fixed to the vertical plate 1002. The exhaust fan 7 is fixed above the rear part of the horizontal plate 1001. The front part of the horizontal plate 1001 is provided with a guide groove 1005 corresponding to the smoke exhaust pipe 9. The upper edge of the small bracket 14 is provided with a dovetail groove 1401 parallel to the guide groove 1005. The horizontal plate 1001 is provided with a dovetail-shaped guide rail 1004 that cooperates with the dovetail groove 1401.

[0025] Working principle:

[0026] 1. When in use, place the pressure vessel 16 to be sprayed on the pressure vessel support turntable 17. The telescopic rod of the lifting cylinder 20 retracts, driving the horizontal support arm 19, bearing 18 and pressure block 21 downward. The pressure block 21 presses against the top of the head of the pressure vessel 16 to achieve clamping and positioning of the pressure vessel 16.

[0027] 2. During initial spraying, the nozzle 12 is positioned at its upper longitudinal limit. Driven by the lead screw transmission mechanism, the nozzle 12 reciprocates in the longitudinal direction. Simultaneously, the pressure vessel support turntable 17 rotates the pressure vessel 16. Together, they achieve the spraying operation on the outer surface of the pressure vessel 16. During this process, based on feedback data from the laser rangefinder 13, the horizontal electric telescopic rod 15 adjusts the extension and retraction of its telescopic end, thereby adjusting the distance between the nozzle 12 and the corresponding position on the pressure vessel 16 to ensure effective spraying.

[0028] 3. During the spraying process, the dust collection hood 11 absorbs the overflowing dust, and then the dust is conveyed to the factory's flue gas treatment pipeline by the exhaust fan 7 for environmental protection treatment, which greatly reduces the pollution to the environment.
