Technical Field

[0001] This utility model relates to the field of pressure vessel technology, specifically to a pressure vessel anti-corrosion coating spraying device. Background Technology

[0002] A pressure vessel is a sealed container that holds gas or liquid under pressure. It is a type of closed container capable of withstanding pressure. Pressure vessels have extremely wide applications, playing a vital role in many sectors, including industry, civil use, military, and scientific research. After production, pressure vessels require a layer of anti-corrosion coating to improve their corrosion resistance.

[0003] In existing technologies, pressure vessel spraying is mostly done manually, which leads to high labor intensity and low spraying efficiency. While some pressure vessel spraying is done using automatic spraying equipment, the coating cannot be dried quickly after spraying. Therefore, it is necessary to propose a pressure vessel anti-corrosion coating spraying device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a pressure vessel anti-corrosion coating spraying device, which is convenient for automatically spraying pressure vessels to reduce labor intensity and improve spraying efficiency, and can quickly dry the pressure vessel after spraying.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure vessel anti-corrosion coating spraying device, comprising a support plate, a steering column rotatably connected to the upper end of the support plate, a steering plate fixedly connected to the upper end of the steering column, three evenly distributed turntables rotatably connected to the upper end of the steering plate, a placement plate fixedly connected to the upper end of each of the three turntables, a connecting frame fixedly connected to the upper end of the support plate, two electric telescopic rods installed at the upper end of the connecting frame, the output ends of the two electric telescopic rods respectively passing through the two connecting frames and fixedly connected to motor housings, a rotating shaft rotatably connected to the lower end of each of the two motor housings, the two rotating shafts being driven by a first motor installed inside the two motor housings, and an anti-slip pressure plate fixedly connected to the lower end of each of the two rotating shafts;

[0006] A drive mechanism is provided on the lower side of the steering column;

[0007] A vertical plate is installed on the upper end of the support plate, and a connecting plate is fixedly connected to the right end of the vertical plate. A lead screw is rotatably connected between the connecting plate and the support plate. A lifting block is threadedly connected to the outer wall of the lead screw. A temporary storage box is installed on the right end of the lifting block. A nozzle is connected to the right end of the temporary storage box. A material pump with its discharge end extending into the upper end of the temporary storage box is installed.

[0008] A hot air blower is installed at the upper end of the support plate, and an air duct is installed at the upper end of the hot air blower. Multiple air outlets are connected to the outer wall of the air duct, and the air outlet of the hot air blower extends into the interior of the air duct.

[0009] To facilitate the rotation of the steering column, in a preferred embodiment of the pressure vessel anti-corrosion coating spraying device of this utility model, the driving mechanism includes a connecting shaft fixedly connected to the lower end of the steering column and passing through a support plate. A worm gear is installed at the lower end of the connecting shaft, and a drive box is installed at the lower end of the support plate. A worm gear meshing with the worm gear is rotatably connected inside the drive box, and the worm gear is driven by a second motor installed at the right end of the drive box.

[0010] To facilitate the positioning of the pressure vessel, as a preferred embodiment of the pressure vessel anti-corrosion coating spraying device of this utility model, shallow positioning grooves are provided at the upper ends of the three placement plates.

[0011] To improve the stability of the lifting block's movement, in a preferred embodiment of the pressure vessel anti-corrosion coating spraying device of this utility model, the lifting block is slidably connected to the right end of the vertical plate via a slide rail.

[0012] To prevent the output shafts of the two electric telescopic rods from being twisted, in a preferred embodiment of the pressure vessel anti-corrosion coating spraying device of this utility model, the upper ends of the two motor boxes are each fixedly connected to two through connecting frames and slidably connected to them.

[0013] To facilitate the rotation of the lead screw, in a preferred embodiment of the pressure vessel anti-corrosion coating spraying device of this utility model, the lead screw is driven by a third motor mounted on the upper end of the connecting plate.

[0014] To facilitate support of the steering plate, as a preferred embodiment of the pressure vessel anti-corrosion coating spraying device of this utility model, the lower end of the steering plate is equipped with four evenly distributed universal ball bearings.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The pressure vessel on the left rotates, and paint is sprayed onto its outer wall through the nozzle. The nozzle then moves downwards a certain distance at intervals, completing the spraying of one pressure vessel. After spraying, the anti-slip pressure plate on the left moves upwards, and the steering plate rotates 120 degrees clockwise, moving the pressure vessel on the right front to the left for further spraying. Simultaneously, the pressure vessel on the right rear rotates, and hot air is blown onto its surface through multiple nozzles. This allows for rapid drying of the pressure vessel after spraying. Once the pressure vessel on the left side has finished spraying and the pressure vessel on the right rear side has finished drying, the two anti-slip pressure plates move upwards and are rotated 120 degrees clockwise by the steering plate. This allows the dried pressure vessel to move to the right front side, where it can be removed and other pressure vessels to be sprayed can be placed. This method further facilitates automatic spraying of the pressure vessels, reducing labor intensity and improving spraying efficiency. Attached Figure Description

[0022] Please see Figures 1 to 4A pressure vessel anti-corrosion coating spraying device includes a support plate 1, a steering column 2 rotatably connected to the upper end of the support plate 1, a steering plate 3 fixedly connected to the upper end of the steering column 2, three evenly distributed turntables 4 rotatably connected to the upper end of the steering plate 3, a placement plate 5 fixedly connected to the upper end of each of the three turntables 4, a connecting frame 14 fixedly connected to the upper end of the support plate 1, two electric telescopic rods 15 installed on the upper end of the connecting frame 14, the output ends of the two electric telescopic rods 15 respectively passing through the two connecting frames 14 and fixedly connected to motor boxes 16, a rotating shaft 17 rotatably connected to the lower end of each of the two motor boxes 16, the two rotating shafts 17 being driven by a first motor 19 installed inside the two motor boxes 16 respectively, and an anti-slip pressure plate 18 fixedly connected to the lower end of each of the two rotating shafts 17.

[0023] A drive mechanism is provided on the lower side of the steering column 2;

[0024] A vertical plate 7 is installed on the upper end of the support plate 1. A connecting plate 20 is fixedly connected to the right end of the vertical plate 7. A screw 8 is rotatably connected between the connecting plate 20 and the support plate 1. A lifting block 10 is threadedly connected to the outer wall of the screw 8. A temporary storage box 11 is installed on the right end of the lifting block 10. A nozzle 13 is connected to the right end of the temporary storage box 11. A material pump 12 with its discharge end extending into the upper end of the temporary storage box 11 is installed.

[0025] A hot air blower 21 is installed on the upper end of the support plate 1. A duct 22 is installed on the upper end of the hot air blower 21. Multiple air outlets 23 are connected to the outer wall of the duct 22. The air outlet of the hot air blower 21 extends into the interior of the duct 22.

[0026] In this embodiment: When in use, first place a pressure container to be sprayed on the right front side placement plate 5, and let the lower end of the pressure container enter the interior of the positioning shallow groove 6. Then, the drive mechanism drives the steering plate 3 to rotate 120 degrees clockwise, and at the same time drives the steering plate 3, three turntables 4, three placement plates 5 and the pressure container to rotate 120 degrees clockwise, so that the pressure container on the right front side moves to the left side, and the placement plate 5 on the right rear side moves to the right front side. Then, place another pressure container on the right front side placement plate 5. Then, rotate the steering plate 3 clockwise 120 degrees, and place another pressure container on the right front side placement plate 5.

[0027] After the pressure vessel is placed, the electric telescopic rod 15 on the left moves the motor box 16, the rotating shaft 17, and the anti-slip pressure plate 18 downwards. This causes the anti-slip pressure plate 18 to press down on the upper part of the pressure vessel. Then, the first motor 19 on the left rotates the rotating shaft 17 and the anti-slip pressure plate 18, causing the pressure vessel to rotate along with the placement plate 5 and turntable 4. Simultaneously, a sufficiently long hose connected to the feed end of the pump 12 draws paint into the storage tank 11, which is then sprayed onto the outer wall of the pressure vessel through the nozzle 13. The screw 8 rotates, causing the lifting block 10, storage tank 11, and nozzle 13 to move downwards a certain distance at regular intervals, thus completing the spraying of one pressure vessel. After spraying, the anti-slip pressure plate 18 moves upwards, and the steering plate 3 rotates 120 degrees clockwise, allowing the right front side to... The pressure vessel moves to the left side, and the same steps are repeated to spray the pressure vessel that has moved to the left side. At the same time, the anti-slip pressure plate 18 on the right side presses the pressure vessel that has moved to the right rear side after spraying, and makes the pressure vessel on the right rear side rotate. At the same time, the hot air blower 21 sends hot air into the air duct 22 and blows it onto the surface of the pressure vessel that has moved to the right rear side through multiple air outlets 23, so as to achieve the purpose of quickly drying the pressure vessel after spraying. After the pressure vessel that has moved to the left side is finished being sprayed and the pressure vessel that has moved to the right rear side is finished drying, the two anti-slip pressure plates 18 move upward, and then the steering plate 3 rotates 120 degrees clockwise again, so that the dried pressure vessel can move to the right front side, so that the dried pressure vessel can be removed and other pressure vessels to be sprayed can be placed there. In this way, it is further convenient to automatically spray the pressure vessels, so as to reduce labor intensity and improve spraying efficiency.

[0028] As a technical optimization of this utility model, the drive mechanism includes a connecting shaft 24 fixedly connected to the lower end of the steering column 2 and passing through the support plate 1. A worm gear 25 is installed at the lower end of the connecting shaft 24, and a drive box 26 is installed at the lower end of the support plate 1. A worm 27 that meshes with the worm gear 25 is rotatably connected inside the drive box 26. The worm 27 is driven by a second motor 28 installed at the right end of the drive box 26.

[0029] In this embodiment: the second motor 28 drives the worm gear 27 to rotate, which in turn drives the worm wheel 25 and the connecting shaft 24 to rotate, and at the same time drives the steering column 2 to rotate.

[0030] As a technical optimization of this utility model, the upper ends of the three placement plates 5 are all provided with positioning shallow grooves 6.

[0031] In this embodiment, three shallow positioning grooves 6 are provided to facilitate the positioning of the pressure vessel.

[0032] As a technical optimization of this utility model, the lifting block 10 is slidably connected to the right end of the vertical plate 7 via a slide rail.

[0033] In this embodiment, a slide rail is provided to improve the stability of the movement of the lifting block 10.

[0034] As a technical optimization of this utility model, the upper ends of the two motor boxes 16 are fixedly connected to two through connecting frames 14 and slide rods that are slidably connected to them.

[0035] In this embodiment, four sliding rods are provided to prevent the output shafts of the two electric telescopic rods 15 from being twisted.

[0036] As a technical optimization of this utility model, the lead screw 8 is driven by a third motor 9 installed on the upper end of the connecting plate 20.

[0037] In this embodiment, a third motor 9 is provided to drive the lead screw 8 to rotate.

[0038] As a technical optimization of this utility model, four evenly distributed universal ball bearings are installed at the lower end of the steering plate 3.

[0039] In this embodiment: by setting four evenly distributed universal balls, since the lower ends of the four universal balls are in contact with the upper end of the support plate 1, the steering plate 3 can be supported.

[0040] Working principle: In use, first place a pressure vessel to be sprayed on the right front side placement plate 5, and make the lower end of the pressure vessel enter the positioning shallow groove 6. Then, the second motor 28 drives the worm gear 27 to rotate, which in turn drives the worm wheel 25 and the connecting shaft 24 to rotate, thereby driving the steering column 2 and steering plate 3 to rotate 120 degrees clockwise. At the same time, the steering plate 3, three turntables 4, three placement plates 5 and the pressure vessel rotate 120 degrees clockwise, so that the pressure vessel on the right front side moves to the left side, and the placement plate 5 on the right rear side moves to the right front side. Then, place another pressure vessel on the right front side placement plate 5. Then, rotate the steering plate 3 clockwise 120 degrees, and place another pressure vessel on the right front side placement plate 5.

[0041] After the pressure vessel is placed, the electric telescopic rod 15 on the left drives the motor box 16, the rotating shaft 17, and the anti-slip pressure plate 18 on the left to move downwards. This allows the anti-slip pressure plate 18 to press down on the upper part of the pressure vessel on the left. Then, the first motor 19 on the left drives the rotating shaft 17 and the anti-slip pressure plate 18 to rotate, causing the pressure vessel on the left to rotate along with the placement plate 5 and turntable 4. Simultaneously, a sufficiently long hose connected to the feed end of the pump 12 pumps the paint into the storage tank 11, which is then sprayed onto the outer wall of the pressure vessel on the left through the nozzle 13. The third motor 9 drives the lead screw 8 to rotate, causing the lifting block 10, the storage tank 11, and the nozzle 13 to move downwards a certain distance at regular intervals, thus completing the spraying of one pressure vessel. After spraying, the anti-slip pressure plate 18 on the left moves upwards, and the steering plate 3 rotates 120 degrees clockwise, thereby allowing the pressure vessel to... The pressure container on the right front side moves to the left side, and the same steps are repeated to spray the pressure container that has moved to the left side. At the same time, the anti-slip pressure plate 18 on the right side presses the pressure container that has moved to the right rear side after spraying, and makes the pressure container on the right rear side rotate. At the same time, the hot air blower 21 sends hot air into the air duct 22 and blows it onto the surface of the pressure container that has moved to the right rear side through multiple air outlets 23, so as to achieve the purpose of quickly drying the pressure container after spraying. After the pressure container that has moved to the left side is finished being sprayed and the pressure container that has moved to the right rear side is finished drying, the two anti-slip pressure plates 18 move upward, and then the steering plate 3 rotates 120 degrees clockwise again, so that the dried pressure container can move to the right front side, so that the dried pressure container can be removed and other pressure containers to be sprayed can be placed there. In this way, it is further convenient to automatically spray the pressure containers, so as to reduce labor intensity and improve spraying efficiency.
