Description

Technical Field

[0001] This utility model relates to the field of metallurgical machinery technology, and in particular to a pre-alloyed powder water-air combined atomization device. Background Technology

[0002] Currently, in the process of metallurgical atomization powder formation, the powder forming device has changed from the past grinding or collision powder formation to the current gas-liquid powder formation. However, gas-liquid powder formation requires dissolving the gas in water first and then spraying it out under high pressure, which is complex in structure, process and difficult to install. Therefore, a pre-alloyed powder water-gas combined atomization device is needed.

[0003] The patent titled "A Pre-alloy Powder Water-Air Combined Atomization Device" (patent application number: 201521017396.7) discloses a pre-alloy powder water-air combined atomization device, which includes an atomizing cylinder, an air pipe, a water pipe, a leak bag, and a liquid inlet pipe. The atomizing cylinder has a feed inlet at its top, a leak bag at the feed inlet, and a liquid inlet pipe at the connection between the leak bag and the feed inlet. Air pipes are located on both sides of the feed inlet, and the liquid inlet pipe has air holes. Filter screens are located on both sides of the liquid inlet pipe. A water pipe is located on one side of the atomizing cylinder, and a nozzle is located at the connection between the water pipe and the atomizing cylinder. The atomizing cylinder has a discharge port at its bottom. In summary, this utility model has the advantages of simple structure, novel design, suitability for factory operation, simple operation, easy installation, high powder formation rate, and rapid cooling.

[0004] In the above case, the cooling efficiency of the atomizing liquid inside the atomizing cylinder is low and the cooling is uneven, which brings inconvenience to the use of the device. In addition, since the filter screen is located below the air pipe, when the gas is sprayed from the air pipe to atomize the molten metal, it will impact the filter screen and change the direction of the atomized molten metal, causing the atomized molten metal to scatter, which reduces the practicality of the device.

[0005] Therefore, it is necessary to propose a pre-alloyed powder water-air combined atomization device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a pre-alloyed powder water-air combined atomization device to solve the problems mentioned in the background art, such as low cooling efficiency and uneven cooling, which bring inconvenience to the use of the device. In addition, since the filter screen is located below the air pipe, when the gas is sprayed from the air pipe to atomize the molten metal, it will impact the filter screen and change the direction of the atomized molten metal, causing the atomized molten metal to scatter, which reduces the practicality of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pre-alloyed powder water-air combined atomization device, including an atomizing cylinder, a feed pipe fixedly connected to the top of the atomizing cylinder, a leak box fixedly connected to the top of the feed pipe, and an air pipe fixedly connected to the inner wall of the feed pipe.

[0008] The atomizing cylinder is equipped with an atomizing cooling assembly, which includes a support block, a support frame, a waterproof motor, a water collection jacket, and a nozzle.

[0009] The top of the support block is fixedly connected to the bottom of the support frame, the top of the support frame is fixedly connected to the bottom of the waterproof motor, the bottom end of the output shaft of the waterproof motor is fixedly connected to the top of the water collection sleeve, and the side of the water collection sleeve is fixedly connected to the side of the nozzle.

[0010] Preferably, the bottom of the water collection sleeve is rotatably connected to the inside of the top of the support block via a rotating shaft, and the outside of the waterproof motor output shaft is rotatably connected to the inside of the support frame;

[0011] A corrugated expansion tube is fixedly connected to the side of the water collection jacket.

[0012] Preferably, a servo motor is fixedly connected to the bottom of the atomizing cylinder, the top end of the servo motor output shaft is fixedly connected to the bottom of the support frame, and the outside of the servo motor output shaft is rotatably connected to the inside of the bottom end of the atomizing cylinder.

[0013] Preferably, a filter screen is fixedly installed on the inner wall of the feed pipe, and the filter screen is located above the air pipe.

[0014] Preferably, there are two air tubes, and the two air tubes are located on one side and the other side of the liquid inlet pipe, respectively, and the two air tubes are inclined downward at one end of the liquid inlet pipe.

[0015] Preferably, the bottom of the atomizing cylinder is fixedly connected to a discharge pipe.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. By setting up an atomizing cooling component, after the high-pressure gas ejected from the gas pipe atomizes the molten metal, water can be sprayed out through the nozzle. At the same time, the waterproof motor can be turned on, which will drive the water collecting sleeve to rotate back and forth 30 degrees. The water collecting sleeve will drive the nozzle to rotate back and forth, causing the atomized water sprayed from the nozzle to fluctuate, thereby enabling better contact between the atomized molten metal and the atomized molten metal, and cooling the atomized molten metal. This improves the cooling effect of the atomized molten metal and brings convenience to the use of the device.

[0018] 2. After the atomized molten metal has cooled down, the angle of the water collection jacket can be adjusted again using the waterproof motor so that the nozzle tilts toward the inner wall of the atomizing cylinder. Then, the servo motor is turned on, and the servo motor drives the nozzle to rotate, thereby using the nozzle to rinse the inner wall of the atomizing cylinder. This avoids the problem of the atomized molten metal adhering to the inner wall of the atomizing cylinder and being difficult to drain, thus causing waste and making the use of the device more convenient.

[0019] 3. By setting up a leakage box, liquid inlet pipe, filter screen, and air pipe, and since both air pipes are located at one end of the liquid inlet pipe and are inclined downwards, when high-pressure gas is ejected from the air pipe, the high-pressure gas will impact the molten metal along the inclined downward direction, atomizing it and guiding the atomized molten metal. Furthermore, since the filter screen is located above the air pipe, it avoids the problem of the gas ejected from the air pipe impacting the filter screen and changing the direction of the atomized molten metal, causing the atomized molten metal to scatter, thus improving the practicality of the device.

[0024] 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 protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1 - Figure 3The pre-alloy powder water-air combined atomization device shown includes an atomizing cylinder 1, a feed pipe 2 fixedly connected to the top of the atomizing cylinder 1, a leakage box 3 fixedly connected to the top of the feed pipe 2, and an air pipe 6 fixedly connected to the inner wall of the feed pipe 2. A filter screen 5 is fixedly installed on the inner wall of the feed pipe 2, and the filter screen 5 is located above the air pipe 6. There are two air pipes 6, and the two air pipes 6 are located on one side and the other side of the liquid inlet pipe 4, respectively. The two air pipes 6 are both inclined downward at one end of the liquid inlet pipe 4. When the molten metal leaks out from the inlet pipe 4, since both gas pipes 6 are located at one end of the inlet pipe 4 and are inclined downwards, when the gas pipes 6 spray high-pressure gas, the high-pressure gas will impact the molten metal along the inclined downward direction, atomizing it and guiding the atomized molten metal. Furthermore, since the filter screen 5 is located above the gas pipes 6, it avoids the problem that when the gas sprayed from the gas pipes 6 atomizes the molten metal, it will impact the filter screen 5 and change the direction of the atomized molten metal, causing the atomized molten metal to scatter, thus improving the practicality of the device.

[0026] The atomizing cylinder 1 is equipped with an atomizing cooling assembly, which includes a support block 7, a support frame 8, a waterproof motor 9, a water collecting sleeve 10, and a nozzle 11. The top of the support block 7 is fixedly connected to the bottom of the support frame 8, the top of the support frame 8 is fixedly connected to the bottom of the waterproof motor 9, the bottom end of the output shaft of the waterproof motor 9 is fixedly connected to the top of the water collecting sleeve 10, the side of the water collecting sleeve 10 is fixedly connected to the side of the nozzle 11, the bottom of the water collecting sleeve 10 is rotatably connected to the inside of the top of the support block 7 through a rotating shaft, the outside of the output shaft of the waterproof motor 9 is rotatably connected to the inside of the support frame 8, and a corrugated telescopic tube 12 is fixedly connected to the side of the water collecting sleeve 10. After the high-pressure gas ejected from the gas pipe 6 atomizes the molten metal, the water can be atomized and sprayed out using the nozzle 11. At the same time, the waterproof motor 9 can be turned on, which will drive the water collecting sleeve 10 to rotate back and forth by 30 degrees. The water collecting sleeve 10 will drive the nozzle 11 to rotate back and forth, causing the atomized water sprayed from the nozzle 11 to fluctuate, thereby enabling better contact between the atomized molten metal and the atomized molten metal, and cooling the atomized molten metal. This improves the cooling effect of the atomized molten metal and brings convenience to the use of the device.

[0027] In addition, a servo motor 13 is fixedly connected to the bottom of the atomizing cylinder 1. The top end of the output shaft of the servo motor 13 is fixedly connected to the bottom of the support frame 8, and the outside of the output shaft of the servo motor 13 is rotatably connected to the inside of the bottom end of the atomizing cylinder 1. After the atomized molten metal is cooled, the angle of the water collecting sleeve 10 can be adjusted again using the waterproof motor 9, so that the nozzle 11 is tilted towards the inner wall of the atomizing cylinder 1. Then, the servo motor 13 is turned on, and the servo motor 13 will drive the nozzle 11 to rotate, thereby using the nozzle 11 to rinse the inner wall of the atomizing cylinder 1. This avoids the problem of the atomized molten metal adhering to the inner wall of the atomizing cylinder 1 and being difficult to discharge, causing waste, thus bringing convenience to the use of the device.

[0028] Finally, a discharge pipe 14 is fixedly connected to the bottom of the atomizing cylinder 1. The discharge pipe 14 can be used to facilitate the discharge of the cooled and shaped atomized metal powder.

[0029] Working principle: When molten metal leaks out from the inlet pipe 4, since both air pipes 6 are located at one end of the inlet pipe 4 and are inclined downwards, when high-pressure gas is ejected from the air pipes 6, the high-pressure gas will impact the molten metal along the inclined downward direction, atomizing it and guiding the atomized molten metal. Furthermore, since the filter screen 5 is located above the air pipes 6, it avoids the problem of the gas ejected from the air pipes 6 impacting the filter screen 5 and changing the direction of the atomized molten metal, thus preventing the atomized molten metal from scattering. This improves the practicality of the device. After the high-pressure gas ejected from the air pipes 6 atomizes the molten metal, the water can be atomized and sprayed out using the nozzle 11. At the same time, the waterproof motor 9 can be turned on, which will drive the water collection sleeve 10 to reciprocate three times. A 10-degree rotation causes the water collecting sleeve 10 to reciprocate, resulting in fluctuations in the atomized water sprayed from the nozzle 11. This allows for better contact between the atomized molten metal and the nozzle, thus improving the cooling effect and enhancing the usability of the device. After cooling, the angle of the water collecting sleeve 10 can be adjusted again using the waterproof motor 9, tilting the nozzle 11 towards the inner wall of the atomizing cylinder 1. Then, the servo motor 13 is activated, causing the nozzle 11 to rotate and rinse the inner wall of the atomizing cylinder 1. This prevents the atomized molten metal from adhering to the inner wall of the atomizing cylinder 1 and being difficult to drain, thus avoiding waste and further enhancing the usability of the device.
