Description

Technical Field

[0001] This utility model relates to the field of metal processing, specifically a spray device for metal surface anti-corrosion treatment. Background Technology

[0002] Metals are exposed to various environments during production, storage, and use, such as humidity, high temperatures, and corrosive gases. These environmental factors accelerate the corrosion process of metals, thus requiring anti-corrosion treatment of metal surfaces to improve their corrosion resistance.

[0003] In the current anti-corrosion treatment of metal pipes, passivating agents are usually sprayed directly onto the metal surface through a high-pressure nozzle. However, during use and observation, it has been found that this spraying method requires multiple adjustments to the pipes or nozzles because the pipes are stationary, making it difficult to accurately control the coating thickness on the pipe surface.

[0004] Therefore, a spray device for metal surface anti-corrosion treatment is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A spraying device for metal surface anti-corrosion treatment, comprising a housing, a first motor fixedly connected to the middle of the housing; a screw fixedly connected to the output end of the first motor; the screw and the housing are through-connected and rotatably connected; a slider threadedly connected to the middle of the screw; the slider and the housing are slidably connected; a nozzle is provided at the top of the slider; a second motor fixedly connected to one side of the housing; a rotating shaft fixedly connected to the output end of the second motor; a fixing mechanism for fixing pipe fittings is provided in the middle of the rotating shaft; a cylinder fixedly connected to the other side of the housing; a vertical plate rotatably connected to the output end of the cylinder; and a drain pipe connected to the middle of the housing; through the combined action of the second motor and the first motor, the pipe fittings can be uniformly sprayed by the radially moving nozzles while rotating, improving the spraying quality of the anti-corrosion treatment on the pipe fitting surface.

[0007] Preferably, the fixing mechanism includes a fixing plate and a sliding plate; the fixing plate and the rotating shaft are fixedly connected; the sliding plate and the rotating shaft are slidably connected; multiple springs are fixedly connected between the fixing plate and the sliding plate; multiple top plates are slidably connected to the middle of the sliding plate; a connecting rod is rotatably connected to the middle of the top plate; the connecting rod and the fixing plate are both rotatably connected; through the cooperation of the top plate and the connecting rod, when the connecting rod rotates, it will drive the top plate to squeeze the inner wall of the pipe, thereby realizing the fixing work of the device for anti-corrosion treatment of pipes of different sizes, and improving the adaptability and flexibility of the device for fixing pipes of various sizes.

[0008] Preferably, the top plate end has an arc-shaped structure; a protective pad is fixedly connected to the top plate end; because the top plate end has an arc-shaped structure, the contact area between the top plate and the pipe can be increased when the top plate supports the pipe internally. At the same time, by setting the protective pad, the protective pad will also contact the inner wall of the pipe when the top plate supports the pipe internally. Because the protective pad is a flexible structure, the squeezing effect generated when the top plate and the pipe come into contact will be dispersed by the protective pad, reducing the damage to the pipe caused by excessive squeezing by the top plate. At the same time, because the protective pad has a large surface friction coefficient, it will also increase the friction between the top plate and the pipe.

[0009] Preferably, a plurality of ball bearings are rotatably connected to the center of the top plate; the ball bearings are located between the top plate and the slide plate; the top plate slides along the surface of the slide plate under the rotation of the connecting rod. By setting the ball bearings, the ball bearings will also rotate under the contact action when the top plate moves. The ball bearings will reduce the friction between the top plate and the slide plate and reduce the wear of the top plate caused by sliding.

[0010] Preferably, a buffer plate is provided on one side of the upright plate; a damping spring shock absorber is fixedly connected between the buffer plate and the upright plate; multiple sliding rods are fixedly connected to the middle of the buffer plate; the sliding rods and the upright plate are through-connected and slidably connected; when the upright plate abuts against the other end of the pipe, the buffer plate will first come into contact with the pipe, and at the same time the damping spring shock absorber will be compressed under the squeezing action of the buffer plate. The damping spring shock absorber will absorb the impact generated when the buffer plate and the pipe come into contact, and transmit the attenuated impact to the upright plate, thereby reducing the damage caused by the impact when the upright plate and the pipe come into contact.

[0011] Preferably, a filter screen is fixed to the inner wall of the tank; the surface of the filter screen is porous; the filter screen has a V-shaped structure; the spray waste liquid will pass through the filter screen and be filtered by the pores on the surface of the filter screen during the flow inside the tank, reducing the solid impurities contained in the waste liquid and improving the convenience of subsequent recycling.

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1 to 5As shown in the embodiment of this utility model, a spraying device for metal surface anti-corrosion treatment includes a housing 1. A first motor 12 is fixedly connected to the middle of the housing 1. A screw 13 is fixedly connected to the output end of the first motor 12. The screw 13 and the housing 1 are through-connected and rotatably connected. A slider 14 is threadedly connected to the middle of the screw 13. The slider 14 and the housing 1 are slidably connected. A nozzle 15 is provided on the top of the slider 14. A second motor 16 is fixedly connected to one side of the housing 1. A rotating shaft 17 is fixedly connected to the output end of the second motor 16. A fixing mechanism for fixing pipe fittings is provided in the middle of the rotating shaft 17. A cylinder 18 is fixedly connected to the other side of the housing 1. A vertical plate 19 is rotatably connected to the output end of the cylinder 18. A drain pipe 110 is connected to the middle of the housing 1. During operation, metal pipe fittings can be sleeved on the outside of the rotating shaft 17 and fixed by the fixing mechanism. Then, the cylinder 18 can be started. The vertical plate 19 is pressed against the other end of the pipe to stabilize the pipe. Then, the second motor 16 can be started to make the rotating shaft 17 drive the pipe on its surface to rotate. At the same time, the first motor 12 can be started to make the slider 14 move radially along the screw 13 with the nozzle 15. The nozzle 15 can be connected to an external pump body so that the passivating agent can be sprayed onto the surface of the pipe. Because the nozzle 15 moves radially with the slider 14 and the pipe is rotating, the passivating agent can be evenly sprayed onto the surface of the pipe through the nozzle 15 to achieve the anti-corrosion treatment of the metal pipe surface. The waste liquid generated during the passivating agent spraying process will fall into the inside of the tank 1. This waste liquid can be recovered by opening the valve of the drain pipe 110. Through the cooperation of the second motor 16 and the first motor 12, the pipe can be evenly sprayed by the radially moving nozzle 15 while rotating, improving the spraying quality of the anti-corrosion treatment of the pipe surface.

[0025] Please see Figures 2 to 4As shown, the fixing mechanism includes a fixing plate 2 and a sliding plate 22; the fixing plate 2 and the rotating shaft 17 are fixedly connected; the sliding plate 22 and the rotating shaft 17 are slidably connected; multiple springs 23 are fixedly connected between the fixing plate 2 and the sliding plate 22; multiple top plates 24 are slidably connected to the middle of the sliding plate 22; a connecting rod 25 is rotatably connected to the middle of the top plate 24; the connecting rod 25 and the fixing plate 2 are both rotatably connected; when it is necessary to fix the pipe, one end of the pipe can be sleeved on the outside of the rotating shaft 17 and moved along the rotating shaft 17. During the movement of the pipe, it will contact the sliding plate 22 and cause the sliding plate 22 to move along the shaft 17. The device slides along the pivot 17. During this process, the spring 23 is compressed, and the connecting rod 25 rotates to drive the top plate 24 to move along the slide plate 22. Multiple top plates 24 move towards the inner edge of the pipe fitting at the same time until the top plate 24 contacts the inner wall of the pipe fitting and provides internal support, thereby enabling the device to quickly fix pipe fittings of different sizes. Through the cooperation of the top plate 24 and the connecting rod 25, the rotation of the connecting rod 25 drives the top plate 24 to press against the inner wall of the pipe fitting, thereby enabling the device to fix pipe fittings of different sizes during anti-corrosion treatment, improving the adaptability and flexibility of the device in fixing pipe fittings of various sizes.

[0026] Please see Figure 4 As shown, the top plate 24 has an arc-shaped end; a protective pad 3 is fixedly connected to the end of the top plate 24; because the top plate 24 has an arc-shaped end, the contact area between the top plate 24 and the pipe can be increased when the top plate 24 supports the pipe internally. At the same time, by setting the protective pad 3, the protective pad 3 will also contact the inner wall of the pipe when the top plate 24 supports the pipe internally. Because the protective pad 3 is a flexible structure, the squeezing effect generated when the top plate 24 and the pipe come into contact will be dispersed by the protective pad 3, reducing the damage to the pipe caused by excessive squeezing by the top plate 24. At the same time, because the protective pad 3 has a large surface friction coefficient, it will also increase the friction between the top plate 24 and the pipe.

[0027] Please see Figure 4 As shown, a plurality of ball bearings 4 are rotatably connected to the middle of the top plate 24; the ball bearings 4 are located between the top plate 24 and the slide plate 22; the top plate 24 slides along the surface of the slide plate 22 under the rotation of the connecting rod 25. By setting the ball bearings 4, the ball bearings 4 will also rotate under the contact action when the top plate 24 moves. The ball bearings 4 will reduce the friction between the top plate 24 and the slide plate 22 and reduce the wear of the top plate 24 caused by sliding.

[0028] Please see Figure 5As shown, a buffer plate 5 is provided on one side of the upright plate 19; a damping spring shock absorber 53 is fixedly connected between the buffer plate 5 and the upright plate 19; a plurality of sliding rods 52 are fixedly connected to the middle of the buffer plate 5; the sliding rods 52 and the upright plate 19 are through-connected and slidably connected; when the upright plate 19 abuts against the other end of the pipe, the buffer plate 5 will first come into contact with the pipe, and at the same time the damping spring shock absorber 53 will be compressed under the squeezing action of the buffer plate 5. The damping spring shock absorber 53 will absorb the impact generated when the buffer plate 5 and the pipe come into contact, and transmit the attenuated impact to the upright plate 19, reducing the damage caused by the impact when the upright plate 19 and the pipe come into contact.

[0029] Please see Figure 2 As shown, a filter screen 6 is fixed to the inner wall of the box 1; the surface of the filter screen 6 is porous; the filter screen 6 has a V-shaped structure; the spray waste liquid will pass through the filter screen 6 and be filtered by the pores on the surface of the filter screen 6 during the flow inside the box 1, reducing the solid impurities contained in the waste liquid and improving the convenience of its subsequent recycling.

[0030] Working principle: The metal pipe is sleeved on the outside of the rotating shaft 17 and fixed by a fixing mechanism. Then, the cylinder 18 is activated, causing the vertical plate 19 to press against the other end of the pipe, stabilizing the pipe. Next, the second motor 16 is activated, causing the rotating shaft 17 to rotate the pipe on its surface. Simultaneously, the first motor 12 is activated, causing the slider 14 to move radially along the screw 13, carrying the nozzle 15. The nozzle 15 can be connected to an external pump body, allowing the passivating agent to be sprayed onto the pipe surface. Because the nozzle 15 moves radially with the slider 14 while the pipe rotates, the passivating agent can be evenly sprayed onto the pipe surface through the nozzle 15, achieving the desired effect. During the anti-corrosion treatment of metal pipe fittings, the waste liquid generated during the passivating agent spraying process will fall into the interior of the tank 1. This waste liquid can be recovered by opening the valve of the drain pipe 110. When it is necessary to fix the pipe fitting, one end of the pipe fitting can be sleeved on the outside of the rotating shaft 17 and moved along the rotating shaft 17. During the movement of the pipe fitting, it will come into contact with the sliding plate 22 and cause the sliding plate 22 to slide along the rotating shaft 17. During this process, the spring 23 will be in a compressed state, and the connecting rod 25 will also rotate to drive the top plate 24 to move along the sliding plate 22. Multiple top plates 24 will move towards the inner edge of the pipe fitting at the same time until the top plate 24 contacts the inner wall of the pipe fitting and performs corrosion protection. The internal support allows for rapid fixing of pipe fittings of different sizes. Because the top plate 24 has an arc-shaped end, the contact area between the top plate 24 and the pipe fitting is increased when the top plate 24 internally supports the fitting. Simultaneously, the protective pad 3 ensures that it also contacts the inner wall of the pipe fitting during this internal support process. The flexible structure of the protective pad 3 disperses the squeezing force generated when the top plate 24 contacts the fitting, reducing damage to the fitting caused by excessive squeezing. Furthermore, the high surface friction coefficient of the protective pad 3 increases the friction between the top plate 24 and the fitting. Under the rotation of the connecting rod 25, the top plate 24 moves along... The slide plate 22 slides on the surface of the slide plate 22. By setting the ball bearings 4, the ball bearings 4 will also rotate under the contact action when the top plate 24 moves. The ball bearings 4 will reduce the friction between the top plate 24 and the slide plate 22. When the upright plate 19 abuts against the other end of the pipe, the buffer plate 5 will first contact the pipe. At the same time, the damping spring shock absorber 53 will be compressed under the squeezing action of the buffer plate 5. The damping spring shock absorber 53 will absorb the impact generated when the buffer plate 5 contacts the pipe and transmit the attenuated impact to the upright plate 19. During the flow of the spray waste liquid inside the tank 1, it will pass through the filter screen 6 and be filtered by the pores on the surface of the filter screen 6, reducing the solid impurities contained in the waste liquid.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
