Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic powder feeding, and in particular relates to a magnetic powder blowing and dispersing device. Background Art

[0002] In the metallurgical industry, some processes use space smelting technology, that is, using the large specific surface area of ​​powder particles and the fast heat transfer, mass transfer and reaction speed between space and gas to quickly melt magnetic powder in space. In order to improve the melting efficiency of magnetic powder in space, it is usually necessary to break up the magnetic powder when adding materials to avoid magnetic attraction between magnetic powders to form lumps.

[0003] In the existing smelting process, magnetic powder and smelting materials are added in batches. During the process of adding the magnetic powder, the magnetic powder that is magnetically attracted into a mass needs to be broken up by a stirring rod to prevent the magnetic powder from attracting each other and forming a mass during the falling process due to its own magnetic properties. However, when the magnetic powder that is magnetically attracted into a mass is broken up by the stirring rod, the magnetic powder contacts the stirring rod, and the magnetic powder easily adheres to the stirring rod and the container wall to form an accumulation. The accumulated magnetic powder may also affect the rotation of the stirring rod, resulting in a poor dispersion effect. Utility Model Content

[0023] A tank body 1, wherein the top of the tank body 1 is sealed with a tank cover 29, a hopper 2 is provided on the top of the tank cover 29, a discharge pipe 20 is provided at the bottom of the tank body 1, a fan 3 is provided on the top of the tank cover 29, an air pipe 4 is provided inside the top of the tank cover 29, the fan 3 is connected to the air pipe 4 through the pipe body, a plurality of air nozzles 5 for blowing the magnetic powder in the tank body 1 are provided on the surface of the air pipe 4, a connecting pipe 6 is connected to the top of the air nozzle 5, the connecting pipe 6 is connected to the air pipe 4, an air duct 7 is provided inside the air nozzle 5, and a sealing block 8 is slidably connected inside the air duct 7, and air outlets 11 are provided on both sides of the sealing block 8.

[0024] A guide rod 9 is fixedly connected in the air duct 7, and the sealing block 8 is slidably sleeved on the surface of the guide rod 9. A first spring 10 is sleeved on the surface of the guide rod 9. The two ends of the first spring 10 are respectively fixedly connected to the protrusions on the surface of the guide rod 9 and the sealing block 8. Air outlets 11 are provided on both sides of the sealing block 8. The wind in the air duct 7 is evenly blown out from the air nozzle 5 through the air outlets 11 on both sides of the sealing block 8.

[0025] A first motor 12 is provided on the top of the tank cover 29, and a rotating shaft 13 is rotatably connected to the bottom of the tank cover 29. The output shaft of the first motor 12 rotates through the tank cover 29 and is fixedly connected to the rotating shaft 13. A plurality of stirring blades 14 are provided on the surface of the rotating shaft 13. A reinforcing rod 15 is fixedly sleeved on the surface of the rotating shaft 13. Slots 21 are provided at both ends of the reinforcing rod 15. A connecting plate 23 is inserted into the slot 21 through an insert rod 22. A scraper 16 is provided on the surface of the connecting plate 23. The scraper 16 scrapes the inner wall of the tank body 1 while rotating to prevent the magnetic powder from being adsorbed on the inner wall of the tank body 1.

[0026] A support rod 24 is provided in the middle of the rotating shaft 13, and two groups of pressure blocks 25 are slidably connected in one end of the supporting rod 24, and two groups of second springs 26 are fixedly connected between the two groups of pressure blocks 25. One end of the pressure block 25 located in the supporting rod 24 is fixedly connected to a clamping rod 27, and the clamping rod 27 movably penetrates the supporting rod 24. A clamping groove 28 is provided on the surface of the connecting plate 23, and the clamping rod 27 is matched with the clamping groove 28. When the scraper 16 scrapes the inner wall of the tank body 1 back and forth and is worn and needs to be replaced, the rotating shaft 13 is taken out by opening the sealed tank cover 29 and pressing the two clamping rods inward. The pressure block 25 is assembled so that the pressure block 25 compresses the second spring 26, so that the second spring 26 is in a compressed state, so that when the two groups of pressure blocks 25 approach each other, the clamping rod 27 is driven to move and approach each other, so that the clamping rod 27 is disengaged from the clamping groove 28, and the insertion rod 22 on the surface of the connecting plate 23 is pulled out from the slot 21 on the surface of the reinforcing rod 15, so that the scraper 16 is disengaged from the fixation with the reinforcing rod 15, so that a new scraper 16 can be replaced, and if the scraper 16 is damaged after long-term use, it is convenient to quickly replace the scraper 16, and the operation is more convenient.

[0027] A second motor 17 is provided on the surface of the discharge pipe 20, and a rotating rod 18 is rotatably connected inside the discharge pipe 20. A plurality of stirring rods 19 are fixedly connected to the surface of the rotating rod 18. The output shaft of the second motor 17 rotates through the discharge pipe 20 and is fixedly connected to the rotating rod 18. When the second motor 17 works, it drives the rotating rod 18 to rotate, and the rotating rotating rod 18 drives the stirring rod 19 to stir and disperse the magnetic powder discharged from the discharge pipe 20.

[0028] The magnetic powder blowing and breaking device adds magnetic powder into the tank body 1 through the feeding hopper 2, and starts the first motor 12 and the fan 3 to work. When the first motor 12 is working, it drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the stirring blade 14 to break up the magnetic powder added into the tank body 1. While the stirring blade 14 breaks up the magnetic powder, the wind generated by the fan 3 blows the wind into the tank body 1 through the air nozzle 5 on the surface of the air pipe 4, and when the wind enters the air duct 7 of the air nozzle 5 through the connecting pipe 6, the wind in the air duct 7 squeezes the sealing block 8 to move downward, and the first spring 10 is stretched during the downward movement of the sealing block 8. When the sealing block 8 moves, the air outlets 11 on both sides are separated from the seal with the inner wall of the air nozzle 5, and the wind in the air duct 7 is vented. The air is blown out evenly from the air nozzle 5 through the air outlets 11 on both sides of the sealing block 8, so that the magnetic powder is dispersed by the wind in the tank body 1, and the particles are prevented from agglomerating and adhering to the stirring blade 14. The wind blown out from the air nozzle 5 can also accelerate the dispersion process by blowing away the magnetic powder, thereby improving the efficiency of the magnetic powder dispersion. When the fan 3 stops working, the sealing block 8 is not squeezed by the wind, and the first spring 10 rebounds and drives the sealing block 8 to move upward, so that the air outlets 11 on both sides of the sealing block 8 are sealed with the inner wall of the air nozzle 5 again, thereby sealing the air duct 7, and preventing the magnetic powder from entering the air nozzle 5 when the air nozzle 5 does not blow, thereby blocking the air duct 7 in the air nozzle 5.

[0029] After the magnetic powder is dispersed by the stirring blade 14, the control valve on the surface of the discharge pipe 20 is opened, and the dispersed magnetic powder is discharged from the tank body 1 through the discharge pipe 20. While the magnetic powder is being discharged, the second motor 17 works to drive the rotating rod 18 to rotate, and the rotating rotating rod 18 drives the stirring rod 19 to stir and disperse the magnetic powder discharged from the discharge pipe 20, so as to avoid the magnetic powder being attracted to each other and forming blocks when the magnetic powder is discharged, which affects the subsequent use.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
