Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic powder spraying, in particular to a magnetic powder spraying device of a magnetic powder flaw detector. Background Art

[0002] Magnetic particle detector is an important non-destructive testing instrument, mainly used to detect surface and near-surface defects of metal materials. Magnetic powder spraying is mainly to evenly cover the surface to be tested with magnetic powder in order to detect defects on the surface and inside of the material.

[0003] The magnetic powder spraying device of the current magnetic particle inspection machine usually uses a magnetic powder spray gun to mix magnetic powder with air to form a magnetic powder mixture, and then evenly spray it on the surface to be inspected.

[0004] The magnetic powder spraying device of the current magnetic particle inspection machine will limit the range and distance of the sprayed magnetic powder due to the position of the magnetic powder sprayer when spraying magnetic powder.

[0005] To this end, the utility model provides a magnetic powder spraying device for a magnetic powder flaw detector. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: the magnetic powder spraying device of a magnetic particle flaw detector according to the present invention comprises a base plate; a plurality of universal wheels fixedly connected to the bottom of the base plate; a push rod fixedly connected to the top of the base plate; a flaw detector body fixedly connected to the top of the base plate; a feeding port fixedly connected to the top of the flaw detector body; a water pump fixedly connected to the top of the flaw detector body; a first pipe installed at the top of the water pump; the other end of the first pipe connected to the flaw detector body; a second pipe installed on the side wall of the water pump; a spray head fixedly connected to the other end of the second pipe; a cylinder fixedly connected to the side wall of the second pipe; a plurality of motors fixedly connected to the inner side wall of the cylinder; and a fan rotatably connected to the output end of the motor. By pushing the push rod to move the universal wheels to the appropriate position, the problem of the magnetic powder spraying range and distance being limited by the position of the magnetic powder sprayer can be solved. Then, starting the motor to start the fan rotation can increase the range of magnetic powder spraying and make the magnetic powder more dense.

[0008] Preferably, a plurality of first support rods are fixedly connected to the inner side wall of the cylinder; the first support rods are arranged around the nozzle. The wind generated by the rotation of the fan passes through the first support rods, which increases the gas flow rate and makes the wind stronger, thereby further enhancing the range of the magnetic powder spray.

[0009] Preferably, an isolation net is installed on the side wall of the cylinder; the isolation net is arranged in an arc shape. The isolation net blocks dust from entering the cylinder, thereby reducing the possibility of dust and magnetic powder being sprayed out together, and also reducing the possibility of failure to meet inspection standards due to excessive dust on the mold surface.

[0010] Preferably, a triangular support frame is fixedly connected to the side wall of the cylinder; a collection frame is slidably connected to the inner side wall of the triangular support frame; a second support rod is fixedly connected to the bottom of the collection frame; a plurality of springs are mounted on the side wall of the second support rod; and the other end of each spring is connected to the side wall of the triangular support frame. The springs deform to move the collection frame below the nozzle, and the remaining magnetic powder falls into the collection frame, thereby collecting the magnetic powder and allowing it to be recycled.

[0011] Preferably, a magnet is fixedly connected to the bottom of the inner side wall of the collecting frame. The magnet absorbs the magnetic powder, which can reduce the situation where the magnetic powder flies up again due to the spring returning to its original state after the second support rod stops moving.

[0012] Preferably, a scraper is slidably connected to the bottom of the inner side wall of the collection frame; the scraper is in contact with the side wall of the magnet, and the magnetic powder on the surface of the magnet is scraped together by moving the scraper to facilitate collection.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The magnetic powder spraying device of a magnetic particle flaw detector described in the utility model can solve the problem of the position of the magnetic powder sprayer limiting the range and distance of the magnetic powder spraying by pushing the push rod to move the universal wheel to a suitable position. Then, the motor is started to rotate the fan, which can increase the range of the magnetic powder spraying and make the magnetic powder more dense.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1 to 3 As shown, a magnetic powder spraying device of a magnetic particle flaw detector described in an embodiment of the present invention includes a base plate 1; a plurality of universal wheels 12 are fixedly connected to the bottom of the base plate 1; a push rod 13 is fixedly connected to the top of the base plate 1; a flaw detector body 14 is fixedly connected to the top of the flaw detector body 14; a feeding port 15 is fixedly connected to the top of the flaw detector body 14; a water pump 16 is fixedly connected to the top of the water pump 16; a first pipe 17 is installed on the top of the water pump 16; the other end of the first pipe 17 is connected to the flaw detector body 14; a second pipe 18 is installed on the side wall of the water pump 16; a nozzle 19 is fixedly connected to the other end of the second pipe 18; a cylinder 110 is fixedly connected to the side wall of the second pipe 18; a plurality of motors 111 are fixedly connected to the inner wall of the cylinder 110; a fan 112 is rotatably connected to the output end of the motor 111. During operation, the push rod 13 is first pushed to move the universal wheel 12 to the appropriate position. Magnetic powder is then added to the feed port 15. The water pump 16 is then started, and the magnetic powder is sucked into the first pipe 17. It is then ejected from the nozzle 19 through the second pipe 18, spraying the mold with magnetic powder. Simultaneously, while the magnetic powder is being sprayed, the motor 111 is started to rotate the fan 112, generating wind force that propels the magnetic powder further. By pushing the push rod 13 to move the universal wheel 12 to the appropriate position, the problem of the magnetic powder spraying range and distance being limited by the position of the magnetic powder sprayer can be resolved. Starting the motor 111 to rotate the fan 112 can then increase the range of the magnetic powder spray and make the magnetic powder more dense.

[0025] like Figure 1 and Figure 2As shown, the inner wall of the cylinder 110 is fixedly connected to a plurality of first support rods 2; the first support rods 2 surround the nozzle 19. During operation, the fan 112 begins to rotate, and the wind generated by the rotation passes through the first support rods 2 and is blown out. The wind generated by the rotation is concentrated between the first support rods 2, which strengthens the wind force before blowing out. The blown wind then exerts a force on the magnetic powder, allowing it to be sprayed further. The wind generated by the rotation of the fan 112 passes through the first support rods 2, increasing the gas flow rate and making the wind force stronger, which can further enhance the range of the magnetic powder spray.

[0026] like Figures 1 to 3 As shown, the sidewall of the cylinder 110 is mounted with an arc-shaped isolation net 3. During operation, when magnetic powder is sprayed, dust will float around and enter the cylinder 110. The wind from the rotating fan 112 will then blow the dust out, causing the dust and magnetic powder to be blown onto the mold together, resulting in substandard inspection. The isolation net 3 prevents dust from entering the cylinder 110, thereby reducing this possibility. By preventing dust from entering the cylinder 110, the isolation net 3 can reduce the possibility of dust and magnetic powder being sprayed out together, and can also reduce the possibility of substandard inspection due to excessive dust on the mold surface.

[0027] like Figures 1 to 5 As shown, the side wall of the cylinder 110 is fixedly connected to a triangular support frame 4; the inner side wall of the triangular support frame 4 is slidably connected to a collection frame 41; the bottom of the collection frame 41 is fixedly connected to a second support rod 43; a plurality of springs 42 are installed on the side wall of the second support rod 43; the other end of the spring 42 is connected to the side wall of the triangular support frame 4. During operation, after the magnetic powder spraying is completed, there will be residual magnetic powder on the side wall of the nozzle 19. At this time, moving the second support rod 43 can allow the spring 42 to deform, and then the collection frame 41 will also move and move to the bottom of the nozzle 19. The residual magnetic powder will fall into the collection frame 41. After the magnetic powder falls into the collection frame 41, the movement of the second support rod 43 can be stopped. At this time, the spring 42 will return to its original state, and the collection frame 41 will return to its original position, which will not hinder the nozzle 19 from spraying magnetic powder next time. The spring 42 is deformed to move the collecting frame 41 below the nozzle 19 , and the remaining magnetic powder falls into the collecting frame 41 , thereby collecting the magnetic powder and allowing it to be recycled.

[0028] like Figure 4 and Figure 5As shown, a magnet 5 is fixedly attached to the bottom of the inner wall of the collection frame 41. During operation, when residual magnetic powder falls into the collection frame 41, it is attracted by the magnetism of the magnet 5 and falls to the surface of the magnet 5. After that, the movement of the second support rod 43 stops, and the spring 42 returns to its original state. This process can reduce the magnetic powder from floating around. By having the magnet 5 attract the magnetic powder, it can reduce the magnetic powder from flying again due to stopping the movement of the second support rod 43 and then returning the spring 42 to its original state.

[0029] like Figure 5 As shown, a scraper 6 is slidably connected to the bottom of the inner sidewall of the collection frame 41; the scraper 6 engages the sidewall of the magnet 5. During operation, the scraper 6 moves to scrape the magnetic powder inside the collection frame 41 into a pile. The scraper 6 also moves to gather the magnetic powder on the surface of the magnet 5, making it easier to collect.

[0030] Working Principle: First, push the push rod 13 to move the universal wheel 12 to the appropriate position. Then, magnetic powder is added to the feeding port 15. Then, the water pump 16 is started, which draws the magnetic powder into the first pipe 17. From there, it is sprayed through the second pipe 18 and out of the nozzle 19, spraying the mold with the magnetic powder. Simultaneously, while the magnetic powder is being sprayed, the motor 111 is started, causing the fan 112 to rotate, generating wind force that propels the magnetic powder farther. By pushing the push rod 13 to move the universal wheel 12 to the appropriate position, the problem of the magnetic powder sprayer's position limiting the range and distance of the magnetic powder spray can be resolved. Then, starting the motor 111 and rotating the fan 112 increases the range and density of the magnetic powder spray. The fan 112 begins to rotate, generating wind that blows through the first support rods 2 and outward. The wind generated by the rotation is concentrated between the first support rods 2, increasing the wind force before being blown outward. This wind force exerts a force on the magnetic powder, propagating it farther. The wind generated by the rotation of the fan 112 passes through the first support rod 2, which increases the gas flow rate and makes the wind stronger, further enhancing the range of the magnetic powder spraying. When the magnetic powder is sprayed, dust will be scattered and then enter the cylinder 110. The wind blown out by the rotation of the fan 112 will blow the dust out, causing the dust and magnetic powder to be blown onto the mold together, resulting in substandard inspection. The isolation net 3 will prevent dust from entering the cylinder 110, which can reduce the occurrence of this situation. By using the isolation net 3 to prevent dust from entering the cylinder 110, the situation of dust and magnetic powder being sprayed out together can be reduced. At the same time, it can also reduce the cause of excessive dust on the mold surface that causes substandard inspection. After the magnetic powder spraying is completed, there will be residual magnetic powder on the side wall of the nozzle 19. At this time, moving the second support rod 43 can cause the spring 42 to deform, and then the collection frame 41 will also move and move to the bottom of the nozzle 19. The residual magnetic powder will fall into the collection frame 41. After the magnetic powder falls into the collection frame 41, you can stop moving the second support rod 43. At this time, the spring 42 will return to its original state, and the collection frame 41 will return to its original position, which will not hinder the nozzle 19 from spraying magnetic powder next time. By deforming the spring 42, the collection frame 41 is moved to the bottom of the nozzle 19, and then the residual magnetic powder will fall into the collection frame 41, which can collect the magnetic powder and can be recycled. When the residual magnetic powder falls into the magnetic powder in the collection frame 41, it will be attracted by the magnetism of the magnet 5 and then fall on the surface of the magnet 5. After that, stopping moving the second support rod 43 and then the spring 42 returning to its original state can reduce the situation where the magnetic powder floats around. The magnet 5 attracts the magnetic powder, which can reduce the chance of the magnetic powder flying up again when the second support rod 43 stops moving and the spring 42 returns to its original position. The movable scraper 6 scrapes the magnetic powder in the collection frame 41 into a pile. The movable scraper 6 scrapes the magnetic powder on the surface of the magnet 5 together, making it easier to collect.
