Water mist connection device for ship rust removal

Abstract

This invention relates to the field of ship rust removal technology and discloses a water mist connection device for ship rust removal, including two quick-release sandblasting sockets, a reducing connector, and a Y-type cast iron tee. Multiple impellers are fixedly fitted onto the outer surface of the support shaft, and half-gears are fixedly fitted onto the outer surface of the support shaft. Guide plates are fixedly fitted onto the outer surfaces of the rotating shaft and the transmission shaft on the side away from the rotating shaft. An atomizing nozzle is fixedly connected to the other end of the guide box. The impact force of the liquid flow strikes the impellers, causing the support shaft to rotate, which in turn causes the half-gears on it to rotate. These, in conjunction with the first and second gears, cause the corresponding guide plates to rotate, thus changing the angle between the two guide plates and guiding the flow in different directions. The flow guided by the guide plates accelerates the liquid flow velocity at the discharge port, resulting in more complete atomization, and finally, the liquid is sprayed out through the atomizing nozzle, thereby further ensuring the wear resistance of the atomizing nozzle.

Description

Technical Field

[0001] This invention relates to the field of ship rust removal technology, specifically to a water mist connection device for ship rust removal. Background Technology

[0002] Water mist blasting, as a new environmentally friendly technology for ship rust removal, has been widely applied and achieved good results. Its environmental protection effect is particularly outstanding compared with the previous dry blasting. Water mist blasting rust removal technology uses special equipment to provide liquid water mist with a pressure greater than that of compressed air. Compressed air pushes dry sand into the sand tube and mixes it inside the sand tube. After the water mist and abrasive are fully mixed in the sand tube, a water-sand mixture is formed and sprayed out through the nozzle to act on the rust removal working surface.

[0003] In the entire system, the water mist connection device plays a bridging role and is a key component of the entire system. However, some thorny problems have been found during use: the high-pressure nozzles inside the device are accelerated to wear under the working conditions of water jet scouring and repeated impact by sand particles, and insufficient liquid atomization further leads to faster nozzle wear and a severely shortened service life, which cannot meet the application requirements. Therefore, a water mist connection device for ship rust removal is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a water mist connection device for ship rust removal, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water mist connection device for ship rust removal, comprising two quick-release sandblasting sockets, a reducing connector, and a Y-type cast iron tee. One end of the reducing connector is connected to a flow guide box. A horizontal plate is fixedly connected inside the flow guide box. A support shaft rotatably passes through the outer surface of the horizontal plate. Multiple impellers are fixedly sleeved on the outer surface of the support shaft. A drive shaft is rotatably connected to both sides of the outer surface of the horizontal plate on the support shaft. A rotating shaft is rotatably connected to one side of the drive shaft on the outer surface of the horizontal plate. A half gear is fixedly sleeved on the outer surface of the support shaft. A flow guide plate is fixedly sleeved on the outer surface of both the rotating shaft and the drive shaft on the side away from the rotating shaft. An atomizing nozzle is fixedly connected to the other end of the flow guide box.

[0006] As a further explanation of the present invention, both ends of the Y-type cast iron tee are fixedly connected to connecting pipes, and the reducing fitting is connected to the Y-type cast iron tee by a telescopic flexible hose. An arc-shaped plate is fixedly connected to the outer surface of one of the connecting pipes, and a slider is movably arranged on the outer surface of the arc-shaped plate. A sleeve plate is provided on the outside of the flow guide box, and a rotating seat is fixedly connected to the outer surface of both the sleeve plate and the slider. A telescopic column is rotatably connected between the two rotating seats.

[0007] As a further explanation of the present invention, the outer surface of the arc plate is provided with an arc groove, and a screw is fixedly connected to the bottom outer surface of the slider. The screw passes through the arc groove, and a nut is threadedly connected to the outer surface of the screw.

[0008] As a further explanation of the present invention, a first gear is fixedly sleeved on the outer surface of both of the transmission shafts, and a second gear is fixedly sleeved on the outer surface of both the rotating shaft and the transmission shaft near the rotating shaft, and the outer surfaces of the two second gears are movably meshed with each other.

[0009] As a further explanation of the present invention, coil springs are fixedly sleeved on the outer surfaces of both drive shafts and rotating shafts, and multiple side plates are fixedly connected to the top outer surface of the cross plate, with the other side of the coil spring fixedly connected to the side plate.

[0010] As a further explanation of the present invention, the telescopic column includes a fixed column and a movable column. The movable column is movably inserted into the interior of the fixed column. Both the movable column and the fixed column have screw holes on their outer surfaces. The movable column has a plurality of screw holes on its outer surface arranged in a linear array. The screw holes of the movable column and the fixed column are internally threaded with adjusting handwheels.

[0011] As a further explanation of the present invention, an arc-shaped rod is fixedly connected to the top outer surface of the arc-shaped plate, and the slider is movably sleeved on the outer surface of the arc-shaped rod.

[0012] As a further illustration of the present invention, the outer surfaces of the half gear, the first gear, the second gear, and the coil spring are all coated with anti-rust paint.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In the water mist connection device for ship rust removal provided by the present invention, the impeller is impacted by the impact force of the liquid flow, causing the support shaft to rotate, thereby causing the half gear on it to rotate. In conjunction with the first gear and the second gear, the transmission shaft and the rotating shaft rotate, driving the corresponding guide plate to rotate. As a result, the included angle between the two guide plates changes, guiding the flow in different directions. The flow guided by the guide plates accelerates the flow velocity of the liquid gathered at the discharge port and atomizes it more fully. Finally, it is sprayed out through the atomizing nozzle, thereby further ensuring the wear resistance of the atomizing nozzle.

[0015] 2. In the water mist connection device for ship rust removal provided by the present invention, by adjusting the length of the telescopic column, the elevation angle of the atomizing nozzle is adjusted, and the slider slides on the arc plate. The slider is limited by the screw and nut, and the lateral tilt angle of the atomizing nozzle is adjusted, so that the tilt angle of the atomizing nozzle can be flexibly adjusted as needed.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1:

[0028] Please refer to the following: Figures 1-8This invention provides a technical solution: a water mist connection device for ship rust removal, comprising two quick-release sandblasting sockets 1, a reducing connector 3, and a Y-type cast iron tee 2. One end of the reducing connector 3 is connected to a flow guide box 4. A horizontal plate 6 is fixedly connected inside the flow guide box 4. A support shaft 7 rotatably passes through the outer surface of the horizontal plate 6. Multiple impellers 8 are fixedly sleeved on the outer surface of the support shaft 7. A drive shaft 10 is rotatably connected to both sides of the outer surface of the horizontal plate 6 on the support shaft 7. A rotating shaft 11 is rotatably connected to one side of one of the drive shafts 10 on the outer surface of the horizontal plate 6. A half gear 9 is fixedly sleeved on the outer surface of the support shaft 7. The rotating shaft 11 and the drive shaft 11 on the side away from the rotating shaft 11 are connected to the drive shaft 10. The outer surface of the shaft 10 is fixedly fitted with guide plates 12, and the other end of the guide box 4 is fixedly connected to an atomizing nozzle 5. Specifically, under the jet action of the liquid flow, it impacts the impeller 8, the impeller 8 drives the support shaft 7 to rotate, the support shaft 7 drives the half gear 9 on it to rotate, so that the corresponding transmission shaft 10 and rotating shaft 11 rotate, thereby driving the guide plates 12 on them to rotate, so that the included angle between the two guide plates 12 changes, and guides the flow in different directions. The flow guided by the guide plates 12 makes the liquid flow rate gathered at the discharge port faster and more fully atomized, and finally sprayed out through the atomizing nozzle 5, thereby further ensuring the wear resistance of the atomizing nozzle 5.

[0029] In this embodiment, a first gear 13 is fixedly sleeved on the outer surface of both transmission shafts 10, and a second gear 14 is fixedly sleeved on the outer surface of both the rotating shaft 11 and the transmission shaft 10 near the rotating shaft 11. The outer surfaces of the two second gears 14 are movably meshed with each other. Specifically, when the half gear 9 rotates and meshes with one of the first gears 13, it drives the second gear 14 on it to rotate. The second gear 14 drives the other second gear 14 to rotate, causing the rotating shaft 11 to rotate, which in turn drives the guide plate 12 on the rotating shaft 11 to rotate. When the half gear 9 meshes with the other first gear 13, it drives the other transmission shaft 10 to rotate, causing the guide plate 12 on it to rotate, thereby changing the included angle between the two guide plates 12.

[0030] In this embodiment, coil springs are fixedly sleeved on the outer surfaces of the two drive shafts 10 and the rotating shaft 11. Multiple side plates are fixedly connected to the top outer surface of the cross plate 6. The other side of the coil spring is fixedly connected to the side plate. Specifically, when the drive shaft 10 and the rotating shaft 11 rotate, the coil spring deforms. When the coil spring returns to its original position, it drives the drive shaft 10 and the rotating shaft 11 to return to their original positions.

[0031] In this embodiment, the outer surfaces of the half gear 9, the first gear 13, the second gear 14, and the coil spring are all coated with anti-rust paint. Specifically, the anti-rust paint increases the anti-rust ability of the half gear 9, the first gear 13, the second gear 14, and the coil spring.

[0032] In the specific implementation process, under the jetting action of the liquid flow, the impeller 8 is impacted, the impeller 8 drives the support shaft 7 to rotate, the support shaft 7 drives the half gear 9 on it to rotate, when the half gear 9 rotates and meshes with one of the first gears 13, it drives the second gear 14 on it to rotate, the second gear 14 drives the other second gear 14 to rotate, causing the rotating shaft 11 to rotate, causing the guide plate 12 on the rotating shaft 11 to rotate. When the half gear 9 meshes with the other first gear 13, it drives the other transmission shaft 10 to rotate, causing the guide plate 12 on it to rotate, thus changing the included angle between the two guide plates 12, guiding the flow in different directions. When the half gear 9 disengages from the first gear 13, it is reset by the coil spring, driving the corresponding transmission shaft 10 and rotating shaft 11 to reset, thus causing the corresponding guide plate 12 to reset. The flow guided by the guide plate 12 accelerates the flow rate of the liquid gathered at the discharge port and makes it more fully atomized, and finally sprays it out through the atomizing nozzle 5, thus further ensuring the wear resistance of the atomizing nozzle 5.

[0033] Example 2:

[0034] Please refer to the following: Figures 1-8 This invention provides a technical solution: A connecting pipe is fixedly connected to both ends of a Y-type cast iron tee 2. A telescopic flexible hose 21 connects the reducing connector 3 to the Y-type cast iron tee 2. An arc-shaped plate 15 is fixedly connected to the outer surface of one of the connecting pipes. A slider 16 is movably arranged on the outer surface of the arc-shaped plate 15. A sleeve plate 17 is arranged on the outside of the flow guide box 4. Rotating seats are fixedly connected to the outer surfaces of both the sleeve plate 17 and the slider 16. A telescopic column 18 is rotatably connected between the two rotating seats. Specifically, the elevation angle of the atomizing nozzle 5 in the vertical position is adjusted by adjusting the length of the telescopic column 18. At this time, the adjusting handwheel is unscrewed, causing the movable column to move inside the fixed column until the angle of the atomizing nozzle 5 is adjusted to a suitable position. Then, the adjusting handwheel is screwed into the screw hole corresponding to the movable column and the fixed column, thereby adjusting the length of the telescopic column 18.

[0035] In this embodiment, an arc-shaped groove is formed on the outer surface of the arc plate 15, and a screw 19 is fixedly connected to the bottom outer surface of the slider 16. The screw 19 passes through the arc-shaped groove, and a nut 20 is threadedly connected to the outer surface of the screw 19. Specifically, by adjusting the position of the slider 16 on the arc plate 15, the tilt angle of the lateral position of the atomizing nozzle 5 is adjusted. At this time, the nut 20 is unscrewed, so that the nut 20 is detached from the screw 19, thereby releasing the slider 16 from its limit and adjusting the position of the slider 16 on the arc plate 15. Then, the nut 20 is screwed into the screw 19 to limit the slider 16.

[0036] In this embodiment, the telescopic column 18 includes a fixed column and a movable column. The movable column is movably inserted inside the fixed column. Both the movable column and the fixed column have screw holes on their outer surfaces. There are several screw holes on the outer surface of the movable column, arranged in a linear array. The screw holes corresponding to the movable column and the fixed column are connected to an adjusting handwheel. Specifically, by unscrewing the adjusting handwheel, the movable column moves inside the fixed column until the angle of the atomizing nozzle 5 is adjusted to a suitable position. Then, the adjusting handwheel is screwed into the screw holes corresponding to the movable column and the fixed column, thereby adjusting the length of the telescopic column 18.

[0037] In this embodiment, an arc-shaped rod is fixedly connected to the top outer surface of the arc plate 15, and the slider 16 is movably sleeved on the outer surface of the arc-shaped rod. Specifically, when the slider 16 slides, it slides on the arc-shaped rod, so that the movement trajectory of the slider 16 is arc-shaped.

[0038] In the specific implementation process, the angle of the atomizing nozzle 5 is adjusted as needed. The elevation angle of the atomizing nozzle 5 in the vertical position is adjusted by adjusting the length of the telescopic column 18. At this time, the adjusting handwheel is unscrewed, allowing the movable column to move inside the fixed column until the angle of the atomizing nozzle 5 is adjusted to the appropriate position. Then, the adjusting handwheel is screwed into the screw hole corresponding to the movable column and the fixed column to adjust the length of the telescopic column 18. The tilt angle of the atomizing nozzle 5 in the lateral position is adjusted by adjusting the position of the slider 16 on the arc plate 15. At this time, the nut 20 is unscrewed, allowing the nut 20 to disengage from the screw rod 19, releasing the slider 16 from its limit, thereby adjusting the position of the slider 16 on the arc plate 15. Then, the nut 20 is screwed into the screw rod 19 to limit the slider 16, keeping the nozzle at a specified angle. When it is necessary to continuously adjust the angle of the atomizing nozzle 5, the telescopic column 18 and the slider 16 do not need to be limited.

[0039] Working Principle: In use, the liquid jet impacts the impeller 8, causing the impeller 8 to rotate. The support shaft 7 rotates, which in turn rotates the half gear 9 on it. When the half gear 9 meshes with one of the first gears 13, it drives the second gear 14 on it to rotate. The second gear 14 drives the other second gear 14 to rotate, causing the rotating shaft 11 to rotate. This causes the guide plate 12 on the rotating shaft 11 to rotate. When the half gear 9 meshes with the other first gear 13, it drives the other transmission shaft 10 to rotate, causing the guide plate 12 on it to rotate. This changes the angle between the two guide plates 12, guiding the flow in different directions. When the half gear 9 disengages from the first gear 13, it is reset by a coil spring, which resets the corresponding transmission shaft 10 and rotating shaft 11, thus resetting the corresponding guide plate 12. The flow guided by the guide plate 12 accelerates the flow rate of the liquid gathered at the discharge port, making it more fully atomized. Finally, it is sprayed out through the atomizing nozzle 5, thus further ensuring the wear resistance of the atomizing nozzle 5.

[0040] Adjust the angle of the atomizing nozzle 5 as needed. Adjust the elevation angle of the atomizing nozzle 5 in its vertical position by adjusting the length of the telescopic column 18. At this time, unscrew the adjusting handwheel to move the movable column inside the fixed column until the angle of the atomizing nozzle 5 is adjusted to the appropriate position. Then, screw the adjusting handwheel into the screw hole corresponding to the movable column and the fixed column to adjust the length of the telescopic column 18. Adjust the tilt angle of the atomizing nozzle 5 in its lateral position by adjusting the position of the slider 16 on the arc plate 15. Then, unscrew the nut 20 to disengage it from the screw rod 19, releasing the slider 16 from its limit and adjusting its position on the arc plate 15. Then, screw the nut 20 back into the screw rod 19 to limit the slider 16, keeping the nozzle at a specified angle. When it is necessary to continuously adjust the angle of the atomizing nozzle 5, the telescopic column 18 and slider 16 do not need to be limited.
