[0002] Stainless steel shot is a metal abrasive used for processing metal materials. It can be used for polishing, grinding, and cleaning the surface of metal materials. Stainless steel shot is usually produced by cutting metal strips and atomizing. The atomizing method involves producing molten stainless steel by atomizing it.

[0004] The aforementioned stainless steel shot atomizing equipment sprays molten stainless steel with a high-speed airflow from the outside.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1 to 6 As shown in the embodiment of the present invention, a stainless steel shot atomization device includes: a melting box 1, a liquid outlet 11 fixed at the bottom of the melting box 1, a support frame 2 fixed outside the melting box 1, a protective cover 3 disposed below the melting box 1, the outer side of the protective cover 3 being fixedly connected to the support frame 2, and an air inlet pipe 31 penetrating one side of the protective cover 3; an adjustment assembly disposed inside the protective cover 3, the adjustment assembly including multiple high-pressure jet nozzles 32 of different diameters disposed near one end of the air inlet pipe 31 near the protective cover 3, a first motor 33 disposed below the end of the air inlet pipe 31 near the high-pressure jet nozzles 32, the first motor 33 being fixed below the air inlet pipe 31 by a connecting plate, a tilting frame 331 fixed at the end of the rotating shaft of the first motor 33, the outer side of the tilting frame 331 being fixedly connected to the multiple high-pressure jet nozzles 32; a cooling assembly disposed below the protective cover 3, a screening assembly disposed below the cooling assembly, the screening assembly including a second motor 51 disposed below the protective cover 3, and a transmission shaft 511 fixed at the end of the rotating shaft of the second motor 51;

[0032] In the production of stainless steel shot, the metal material to be used is placed into the melting tank 1, where it is melted. The molten metal flows out through the outlet 11. During the outflow, external airflow is introduced through the air inlet pipe 31. The air inlet pipe 31 sprays the airflow onto the surface of the molten metal through the high-pressure nozzle 32. The airflow blows the molten metal onto the inner wall of the protective cover 3, where it forms small droplets and slides down the inner wall of the protective cover 3. During the sliding process, heat is conducted to the protective cover 3. The protective cover 3 is made of a material with good thermal conductivity, which allows the heat to continuously evaporate to the outside. At this time, the molten metal falling from the inner wall of the protective cover 3 forms stainless steel shot. When it is necessary to produce stainless steel shot with different outer diameters, the process is started. The first motor 33 drives the tilting frame 331 to rotate. At this time, the tilting frame 331 drives the high-pressure jet nozzle 32 to rotate. The high-pressure jet nozzle 32 that can be switched to be placed at the air outlet of the air inlet pipe 31. The inner diameter of the multiple high-pressure jet nozzles 32 is designed to gradually decrease. The air outlet diameter of the high-pressure jet nozzle 32 after switching becomes smaller. Due to the physical characteristics, the diameter of the high-pressure jet nozzle 32 is inversely proportional to its spray velocity. The smaller the diameter of the high-pressure jet nozzle 32, the greater the spray velocity. The increased velocity allows the high-pressure jet nozzle 32 to spray the molten metal flowing out of the liquid outlet 11 faster and spray more small metal droplets. At this time, the outer diameter of the cooled and formed stainless steel shot will also become smaller, which enables the atomizing equipment to produce stainless steel shot with different outer diameters.

[0033] like Figures 1 to 3 As shown, the adjustment assembly also includes: a telescopic groove 311, which is located at one end of the air intake pipe 31 near the high-pressure jet nozzle 32; a retaining ring 313 is provided inside the telescopic groove 311; a first spring 312 is fixed to the end of the retaining ring 313 away from the high-pressure jet nozzle 32; and the end of the first spring 312 away from the retaining ring 313 is fixedly connected to the inner side of the telescopic groove 311; and a retaining groove 321, which is located at one end of the high-pressure jet nozzle 32 near the air intake pipe 31; the inner diameter of the retaining groove 321 matches the outer diameter of the retaining ring 313.

[0034] During the switching process of the high-pressure jet nozzle 32, the high-pressure jet nozzle 32 pushes the retaining ring 313 to retract into the telescopic groove 311. After the high-pressure jet nozzle 32 separates from the air intake pipe 31, the first spring 312 pushes the retaining ring 313 out. When rotating to the next high-pressure jet nozzle 32, the edge of the high-pressure jet nozzle 32 pushes the retaining ring 313 into the telescopic groove 311. After the high-pressure jet nozzle 32 is aligned with the air intake pipe 31, the first spring 312 pushes the retaining ring 313 into the retaining groove 321. At this time, the high-pressure jet nozzle 32 can be fixed at the air outlet of the air intake pipe 31, which can reduce the air leakage at the connection between the high-pressure jet nozzle 32 and the air intake pipe 31. The telescopic groove 311 and the retaining ring 313 are in a sliding seal connection relationship. The contact surface between the retaining ring 313 and the high-pressure jet nozzle 32 will wear. Wear-resistant flexible materials are selected during material selection, and the wear resistance of the material is tested to estimate the service life of the retaining ring 313 and the high-pressure jet nozzle 32.

[0035] like Figures 1 to 4 As shown, the cooling assembly includes a cooling tank 4 fixed to the bottom of the protective cover 3. A discharge pipe is provided in the middle of the cooling tank 4. A water tank is provided between the cooling tank 4 and the discharge pipe. A water inlet tank 44 is fixed to one end of the cooling tank 4. The water inlet tank 44 is connected to the interior of the cooling tank 4.

[0036] After the stainless steel shot is sprayed onto the inner surface of the protective cover 3, it will instantly evaporate the heat and form a shape. At the same time, it will slide from the inner surface of the protective cover 3 into the interior of the cooling tank 4. A water tank is separated between the cooling tank 4 and the discharge pipe, and the interior of the water tank is filled with water for cooling. The stainless steel shot can be cooled down by the evaporation of water. The cooled stainless steel shot is more solid inside and has less heat, preventing workers from being burned by contact with the stainless steel shot.

[0037] like Figures 1 to 4 As shown, a pusher plate 42 is provided inside the cooling tank 4. The pusher plate 42 is placed inside the water tank of the cooling tank 4, and both ends of the pusher plate 42 are close to the inner wall of the water tank. A rotating rod 421 is movably connected to the top of the pusher plate 42. A transmission rod 43 is provided in the middle of the discharge pipe. The end of the rotating rod 421 away from the pusher plate 42 is slidably connected to the transmission rod 43. The bottom end of the transmission rod 43 is fixedly connected to the top of the transmission shaft 511.

[0038] During the cooling process, the second motor 51 drives the transmission shaft 511 to rotate, the transmission shaft 511 drives the transmission rod 43 to rotate, the transmission rod 43 drives the rotating rod 421 to rotate, and the rotating rod 421 drives the pusher plate 42 to scrape at the bottom of the water tank. The pusher plate 42 can scrape the stainless steel shot at the bottom of the cooling tank 4. During the scraping process, the pusher plate 42 can make the stainless steel shot come into contact with water from other areas, which can accelerate the cooling speed of the stainless steel shot. At the same time, the scraping of the pusher plate 42 can concentrate it together, making it easier to remove it from the inside of the cooling tank 4 later.

[0039] like Figures 1 to 4 As shown, a guide plate 41 is fixed inside the cooling tank 4, and a discharge plate 411 is fixed on one side of the top of the guide plate 41. The guide plate 41 and the discharge plate 411 are fixed inside the water tank of the cooling tank 4, and the guide plate 41 and the discharge plate 411 are arranged on the side of the water tank near the air inlet pipe 31. A lifting rod 422 is fixed at the bottom end of the rotating rod 421 away from the push plate 42. A lifting hole 431 is opened at the top of the transmission rod 43. The lifting rod 422 extends into the lifting hole 431. A second spring 423 is sleeved on the outside of the lifting rod 422. The end of the second spring 423 away from the rotating rod 421 is fixedly connected to the lifting rod 422, and the other end of the second spring 423 is fixedly connected to the inner wall of the lifting hole 431.

[0040] When the pusher plate 42 scrapes the stainless steel shot to the position of the guide plate 41, the stainless steel shot can be moved upward by the guide plate 41. As the pusher plate 42 moves on the surface of the guide plate 41, it will gradually rise. At this time, the pusher plate 42 will be pushed up by the guide plate 41. The pusher plate 42 drives the rotating rod 421 to rise. The rotating rod 421 pulls the lifting rod 422 to extend out from the inside of the lifting hole 431, so that the pusher plate 42 can automatically adapt to the height of the current position. The unloading plate 411 is provided with a slope facing the discharge pipe. When the pusher plate 42 scrapes the stainless steel shot to the top of the unloading plate 411, it can induce the stainless steel shot to slide from the unloading plate 411 into the discharge pipe. The stainless steel shot is discharged from the cooling tank 4 to the next position by the guide of the discharge pipe.

[0041] like Figures 1 to 5 As shown, a water inlet pipe 441 is fixed to the end of the water inlet tank 4 away from the cooling tank 4. The water inlet tank 44 and the water inlet pipe 441 are connected internally. A float ball 442 is installed inside the water inlet tank 44. A lifting rod is fixed to the top of the float ball 442. A guide plate 443 is fixed inside the water inlet tank 44. The lifting rod of the float ball 442 passes through the inside of the guide plate 443. A connecting rod 444 is rotatably connected to the top of the lifting rod near the water inlet pipe 441. A flip plate 445 is rotatably connected to the top of the connecting rod 444 near the water inlet pipe 441. The middle part of the flip plate 445 is rotatably connected to the inside of the water inlet tank 44 near the water inlet pipe 441 through a connecting shaft.

[0042] When the stainless steel shot is cooled inside the cooling tank 4, the water inside the cooling tank 4 will be consumed. If the water is consumed for a long time, the cooling will not be able to continue. Therefore, an external water source is connected through the water inlet pipe 441. When there is enough water inside the cooling tank 4, the buoyancy of the water will cause the float ball 442 to float. The float ball 442 drives the connecting rod 444 to rise upward through the push rod. The connecting rod 444 drives the flip plate 445 to block the water inlet of the water inlet pipe 441. When the water inside the cooling tank 4 is consumed, the float ball 442 will move downward. During the downward movement of the float ball 442, it will drive the connecting rod 444 to pull the flip plate 445 to flip. When the flip plate 445 flips, a gap will be created between it and the water outlet of the water inlet pipe 441. At this time, the water will flow into the water tank 44, which can automatically replenish the water inside the cooling tank 4. When there is enough water inside the cooling tank 4, the float ball 442 will drive the flip plate 445 to automatically block the water outlet of the water inlet pipe 441, which can realize the automatic replenishment of water inside the cooling tank 4.

[0043] like Figures 1 to 7 As shown, the screening assembly also includes a screening box 5 fixed to the bottom of the cooling tank 4. There are three screening boxes 5 arranged vertically. The top of the middle screening box 5 is fixedly connected to the upper screening box 5, and the bottom is fixedly connected to the lower screening box 5. A discharge pipe 52 is fixed on one side of the bottom of the screening box 5, and the closest included angle between the three sets of discharge pipes 52 is 45°. Screening holes 53 are opened at the bottom of the screening box 5. Multiple screening holes 53 are opened at equal intervals. The screening holes 53 at the bottom of the three screening boxes 5 are designed with decreasing inner diameter from top to bottom. A scraper 54 is fixed to the outside of the drive shaft 511. The scraper 54 is placed inside the screening box 5, and the bottom of the scraper 54 is close to the bottom of the inside of the screening box 5.

[0044] After the stainless steel shot cools, it falls from the discharge pipe of the cooling tank 4 into the screening box 5. At this time, the drive shaft 511 rotates, which drives the scraper 54 to rotate. When the scraper 54 rotates, it cleans the bottom of the screening box 5. The cleaning can cause the stainless steel shot inside the screening box 5 to roll. At this time, the stainless steel shot with an unqualified outer diameter will fall from the screening hole 53 into the next layer of screening box 5. The stainless steel shot with a qualified outer diameter will be pushed into the discharge pipe 52 by the scraper 54. The discharge pipe 52 outputs the stainless steel shot to the outside. At the same time, the two layers below will screen the stainless steel shot again. The stainless steel shot after being screened again can be output through the discharge pipe 52. Meanwhile, the outer diameter of the stainless steel shot sprayed by different high-pressure jet nozzles 32 matches the outer diameter of the three-layer screening box 5, which makes it easier to screen stainless steel shot with different outer diameters.

[0045] like Figures 1 to 2 As shown, a receiving hopper 57 is provided below the screening box 5, and the top of the receiving hopper 57 is fixedly connected to the bottom of the cooling tank 4.

[0046] The stainless steel shot remaining after screening in the three-layer screening box 5 has an outer diameter that is too small to be used. The receiving hopper 57 can collect and discharge the last screened stainless steel shot, making it easier to collect the smaller stainless steel shot for subsequent recycling.

[0047] like Figures 1 to 8 As shown, a tilting rod 55 is provided below the screening box 5. A spring piece 551 is fixed to the top of the tilting rod 55. A pusher block 552 is fixed to the end of the spring piece 551 away from the tilting rod 55. A support seat 553 is hinged to the end of the tilting rod 55 near the drive shaft 511. The support seat 553 is fixedly connected to the outside of the spring piece 551.

[0048] During the screening process, some stainless steel shot will have an outer diameter larger than the inner diameter of the screening hole 53, but its outer diameter will be slightly smaller than that of other stainless steel shot. Such shot is prone to getting stuck inside the screening hole 53, preventing the screening hole 53 from screening subsequent stainless steel shot. Therefore, when the drive shaft 511 rotates, it will drive the support seat 553 to rotate. The support seat 553 will drive the flipping rod 55 to rotate at the bottom of the screening box 5. At this time, the flipping rod 55 will drive the spring 551 and the pusher block 552 to rotate. When the pusher block 552 contacts the bottom surface of the screening box 5, it will push the spring 551 to bend. When the pusher block 552 passes through the screening hole 53, the elastic force of the spring 551 will be released. At this time, the spring 551 will push the pusher block 552 to bounce up. The pusher block 552 will extend into the interior of the screening hole 53 and eject the stainless steel shot stuck inside the screening hole 53. This can prevent the stainless steel shot from getting stuck inside the screening hole 53 and causing the screening to stop.

[0049] like Figures 1 to 8 As shown, a coil spring 554 is fixed to the outside of the rotating shaft of the flipping rod 55. The outer side of the coil spring 554 is fixedly connected to the support base 553. A fixing frame 56 is fixed to the bottom of the screening box 5. A support ring 561 is fixed to the top of the fixing frame 56. The support ring 561 is sleeved on the outside of the transmission shaft 511. The opening of the support ring 561 faces the direction of the discharge pipe 52. The top of the support ring 561 is close to the bottom of the flipping rod 55.

[0050] When the flipping rod 55 rotates to the position of the discharge pipe 52, it will be blocked by the discharge pipe 52. To solve this problem, a coil spring 554 is installed between the support base 553 and the rotating shaft of the flipping rod 55, and a support ring 561 is set at the bottom of the flipping rod 55 to support the bottom of the flipping rod 55. When the flipping rod 55 rotates at the top of the support ring 561, the spring 551 and the pusher block 552 work normally. When the flipping rod 55 rotates to the notch of the support ring 561, the flipping rod 55 flips downward under the push of the discharge pipe 52. At this time, the coil spring 554 tightens. After the flipping rod 55 passes the discharge pipe 52, the coil spring 554 drives the flipping rod 55 to rise. At the same time, the slope of the notch of the support ring 561 causes the flipping rod 55 to move back to the upper surface of the support ring 561.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
