Description

Technical Field

[0001] The present invention relates to the field of vanadium-nitrogen alloy processing, and specifically relates to a vanadium-nitrogen alloy processing method and processing equipment. Background Art

[0002] Vanadium-nitrogen alloy is a new type of alloy additive, which can replace ferrovanadium for the production of microalloyed steel. Adding vanadium-nitrogen alloy to steel can improve the comprehensive mechanical properties of steel such as strength, toughness, ductility and thermal fatigue resistance, and make the steel have good weldability. During the production process, it is usually necessary to use a special forming mechanism to press the vanadium-nitrogen alloy into spherical shape.

[0003] The working principle of the current forming device is to put vanadium-nitrogen alloy powder into the device. The powder falls between two pressure rollers in the device, enters the circular grooves on the pressure rollers, and the two pressure rollers can press the powder into spherical shape.

[0004] However, most of the current forming devices are not convenient to clean the powder adhering to the surface of the pressure rollers. It is not convenient to separate the formed small balls from the excess powder when they fall together. Although the prior art has improved the traditional processing equipment, the powder adheres to the roller shaft. After the powder is compacted, it will stick tightly to the roller shaft. Only relying on vibration cannot strip the powder. At the same time, the feeding needs to be uniform. If the feeding is not uniform, the two roller shafts will not be able to extrude the powder into balls. At the same time, the filter plate in this device is set in an inclined state. During this process, although the spherical rough material blocks formed by pressing will roll down along the filter plate, there will still be individual corner materials rolling down together with the powder and the spherical rough material blocks, unable to pass through the filter, resulting in poor separation effect. At the same time, during this process, the flying dust will affect the health of workers and is not conducive to the long-term work of workers.

[0005] In view of this, it is necessary to design a processing equipment for vanadium-nitrogen alloy that can completely separate the spherical rough material blocks and debris powder. At the same time, the equipment uses air flow to collect the debris powder to avoid dust pollution. Summary of the Invention

[0046] The feeding cylinder 1 is arranged vertically.

[0047] The reaction cylinder 2 is fixedly arranged at the lower end of the feeding cylinder 1. One end of the reaction cylinder 2 is formed with a discharge port 3, and the other end is formed with a dust discharge port 4.

[0048] The extrusion and spheroidizing mechanism 5 is arranged at the upper part of the reaction cylinder 2 and includes a first motor 6 and two extrusion roller shafts 9. The first motor 6 is connected to the side wall of the upper part of the reaction cylinder 2. The two extrusion roller shafts 9 are symmetrically arranged inside the reaction cylinder 2. A number of spherical grooves 10 are formed at equal intervals along the circumferential direction on the two extrusion roller shafts 9. The spherical grooves 10 on the two extrusion roller shafts 9 can extrude the materials entering the reaction cylinder 2 into spheres.

[0049] The anti-blocking mechanism 13 is inside the feeding cylinder 1. The anti-blocking mechanism 13 includes two stirring roller shafts 16. The two stirring roller shafts 16 are staggered inside the feeding cylinder 1. A number of stirring rods 17 are formed at equal intervals along the circumferential direction on the two stirring roller shafts 16.

[0050] The screening assembly 18 is arranged below the two extrusion roller shafts 9. The screening assembly 18 includes a first arc-shaped guide plate, a second arc-shaped guide plate, a second motor 19, a first dust guide plate 36, a second dust guide plate 37, a dust removal mechanism 39 and two screening mechanisms 26. The second motor 19 is arranged below the first motor 6. The two screening mechanisms 26 are symmetrically arranged up and down inside the reaction cylinder 2. The screening mechanism 26 can separate the spherical rough blocks and powders. The first dust guide plate 36 is arranged inside the reaction cylinder 2 and on the side of the two screening mechanisms 26 close to the discharge port 3. The second dust guide plate 37 is arranged on the side of the two screening mechanisms 26 close to the dust discharge port 4.

[0051] The dust removal mechanism 39 includes an exhaust fan 40 and a suction machine 41. The exhaust fan 40 is connected to the side wall of the reaction cylinder 2 where the discharge port 3 is formed, and the suction machine 41 is connected to the side wall of the reaction cylinder 2 where the dust discharge port 4 is formed.

[0052] The dust cleaning assembly 42 includes two third motors 43 and two dust cleaning mechanisms 46. The two third motors 43 are symmetrically arranged at one end of the two extrusion roller shafts 9 close to the side wall of the reaction cylinder 2. The two dust cleaning mechanisms 46 are respectively connected to the two third motors 43. The two dust cleaning mechanisms 46 include a number of cleaning brushes 55, and the number of cleaning brushes 55 corresponds one by one to a number of spherical grooves 10 in the same column.

[0053] When the device is operating, raw materials are poured into the upper end of the feeding cylinder 1. Subsequently, the two stirring roller shafts 16 will rotate, which can prevent the raw materials from being blocked in the feeding cylinder 1. Then, the falling raw materials are compacted and formed in the spherical grooves 10 under the extrusion of the two extrusion roller shafts 9. At this time, the raw materials will be divided into debris powder and spherical coarse material blocks. The extruded raw materials continue to fall and enter the reaction cylinder 2 for screening.

[0054] In the reaction cylinder 2, the spherical coarse material blocks and the debris powder will move along the first arc-shaped baffle 32. And part of the debris powder will be separated under the action of the screening mechanism 26. At this time, the screening mechanism 26 located above rotates clockwise, and the screening mechanism 26 located below rotates counterclockwise. During this process, the debris powder and the spherical coarse material blocks can be separated. The debris powder will fall into the suction machine 41 through the lower end of the first arc-shaped baffle 32 and the upper end of the second arc-shaped baffle 33 via the dust discharge port 4 under the combined action of the exhaust fan 40 and the suction machine 41. And the spherical coarse material blocks flow out of the reaction cylinder 2 through the upper end of the second arc-shaped baffle 33 via the discharge port 3 and are collected.

[0055] In order to enable the raw materials to be processed to be extruded into spherical coarse material blocks by the two extrusion roller shafts 9 while being evenly fed, the following features are specifically set:

[0056] The ball extrusion mechanism 5 further includes a first driving gear 7, a driving pulley 11, a driven pulley 12 and two first driven gears 8. The first driving gear 7 is key-connected to the output end of the first motor 6. The two first driven gears 8 are respectively key-connected to the two extrusion roller shafts 9 and mesh with each other. The first driven gear 8 close to the first driving gear 7 meshes with the first driving gear 7. The driving pulley 11 is coaxially key-connected to the first driven gear 8 close to the first driving gear 7. The anti-blocking mechanism 13 further includes a second driving gear 14 and a second driven gear 15. The second driving gear 14 is coaxially key-connected to a stirring roller shaft 16. The driven pulley 12 is coaxially key-connected to the second driving gear 14 and is connected to the driving pulley 11 through a belt. The second driven gear 15 is key-connected to the other stirring roller shaft 16 and meshes with the second driving gear 14. When the device operates, starting the first motor 6 will drive the first driving gear 7 to rotate. The rotation of the first driving gear 7 will drive the first driven gear 8 meshing with it to rotate. Since the two first driven gears 8 mesh with each other, the other first driven gear 8 also rotates, and at this time, the two first driven gears 8 rotate in opposite directions. It can be known that the rotation of the first driven gear 8 will also drive the driving pulley 11 connected to it to rotate. The rotation of the driving pulley 11 will drive the driven pulley 12 to rotate through the belt. The rotation of the driven pulley 12 will drive the second driving gear 14 fixedly connected to it to rotate. The rotation of the second driving gear 14 will drive the second driven gear 15 meshing with it to rotate. Combining the foregoing, it can be seen that at this time, the two extrusion roller shafts 9 rotate in opposite directions, and the two stirring roller shafts 16 rotate in opposite directions. At this time, the raw material to be processed can be evenly fed while being extruded into spherical rough blocks by the two extrusion roller shafts 9.

[0057] In order to drive the two screening mechanisms 26 to rotate in opposite directions, the following features are specifically set:

[0058] The screening assembly 18 further includes a screening gear 20, a driving gear 21, a driving pulley 22, a transfer gear 23, a power pulley 24 and a power gear 25. The screening gear 20 is fixedly connected to the output end of the second motor 19. The driving gear 21 is arranged beside the screening gear 20 and meshes with the screening gear 20. The driving pulley 22 is coaxially arranged with the driving gear 21. The transfer gear 23 is arranged below the driving gear 21. The power pulley 24 is coaxially and fixedly connected to the transfer gear 23. The power pulley 24 is in transmission connection with the driving pulley 22 through a belt. The power gear 25 is arranged beside the transfer gear 23 and meshes with the transfer gear 23. The screening mechanism 26 located above is connected to the driving gear 21, and the screening mechanism 26 located below is connected to the power gear 25. When the device operates, starting the second motor 19 will drive the screening gear 20 to rotate. The rotation of the screening gear 20 will drive the driving gear 21 meshing with it to rotate. The rotation of the driving gear 21 will drive the driving pulley 22 coaxially connected to it to rotate, and the rotation of the driving gear 21 will drive the screening mechanism 26 connected to it to rotate. The driving pulley 22 will drive the power pulley 24 to rotate through the belt. The rotation of the power pulley 24 will drive the transfer gear 23 connected to it to rotate. The rotation of the transfer gear 23 will drive the power gear 25 meshing with it to rotate, and the rotation of the power gear 25 will drive the screening mechanism 26 connected to it to rotate. At this time, it can be known that the rotation direction of the driving gear 21 is opposite to that of the power gear 25, that is, the screening mechanism 26 located above rotates counterclockwise, and the screening mechanism 26 located below rotates clockwise.

[0059] In order to ensure that spherical coarse material blocks will not get stuck in the filter holes, the following features are specifically set:

[0060] The screening mechanism 26 includes a driving roller shaft 27, four screening sleeves 28, four screening insertion rods 31 and a number of pressing springs 30. The driving roller shafts 27 in the two screening mechanisms 26 are respectively connected to the driving gear 21 and the power gear 25. The four screening sleeves 28 are uniformly arranged in an array along the circumferential direction of the driving roller shaft 27. The four screening insertion rods 31 are respectively slidably connected to the four screening sleeves 28. One ends of the number of pressing springs 30 are respectively fixedly connected to the four screening sleeves 28, and the other ends are respectively connected to the four screening insertion rods 31. A number of strip-shaped filter holes 29 are uniformly formed on the four screening sleeves 28 and the four screening insertion rods 31. The eight screening insertion rods 31 are all in contact with the first arc-shaped baffle 32, the second arc-shaped baffle 33, the first dust guide plate 36 and the second dust guide plate 37. When the device operates, it can be known that the rotation directions of the two driving roller shafts 27 are opposite. The rotation of the driving roller shaft 27 will drive the four screening sleeves 28 connected thereto to rotate. The rotation of the four screening sleeves 28 will drive the four screening insertion rods 31 connected thereto to rotate. The four screening insertion rods 31 perform relative sliding with the four screening sleeves 28 respectively through a number of pressing springs 30. During this process, the four movable screening insertion rods 31 can ensure that the material will not fall downward during the screening process, and a number of strip-shaped filter holes 29 can separate the debris powder and the spherical coarse material blocks, and ensure that the spherical coarse material blocks will not be stuck in the strip-shaped filter holes 29.

[0061] In order to enable the debris powder in the reaction cylinder 2 to fall into the suction machine 41 along the lower end of the first arc-shaped baffle 32 and the upper end of the second arc-shaped baffle 33 under the action of the exhaust fan 40, the following features are specifically set:

[0062] The screening assembly 18 further includes a vibration motor 35. The vibration motor 35 is arranged below the second arc-shaped baffle 33 and connected to the second arc-shaped baffle 33. Four limiting through holes 34 are formed at the lower end of the second arc-shaped baffle 33. The four limiting through holes 34 are all slidably connected to the side wall of the reaction cylinder 2 through pin shafts. A number of dust filtering holes 38 are formed on both the first dust guide plate 36 and the second dust guide plate 37. In order to more conveniently discharge the formed spherical coarse material blocks outside the reaction cylinder 2, the start of the vibration motor 35 will drive the second arc-shaped baffle 33 to perform reciprocating movement in the vertical direction. At this time, the spherical coarse material blocks located on the second arc-shaped baffle 33 will move downward along the second arc-shaped baffle 33 and be discharged through the discharge port 3, while the debris powder in the reaction cylinder 2 will fall into the suction machine 41 along the lower end of the first arc-shaped baffle 32 and the upper end of the second arc-shaped baffle 33 through the dust discharge port 4 under the action of the exhaust fan 40.

[0063] In order to be able to perform secondary cleaning on the extrusion roller shaft 9, the following features are specifically set:

[0064] The dust cleaning assembly 42 further includes two supporting brackets 44 and two scraping arc plates 45. The two supporting brackets 44 are symmetrically arranged at one end of the two extrusion roller shafts 9 close to the inner side wall of the reaction cylinder 2. The two dust cleaning mechanisms 46 are fixedly connected to the two supporting brackets 44 respectively. The two scraping arc plates 45 are respectively arranged at the lower ends of the two extrusion roller shafts 9 and are respectively abutted against the lower ends of the two extrusion roller shafts 9. One scraping arc plate 45 abuts against the first arc-shaped baffle 32 through a torsion spring, and the other scraping arc plate 45 abuts against the second arc-shaped baffle 33 through a torsion spring. When the device operates, the two scraping arc plates 45 continuously abut against the lower ends of the two extrusion roller shafts 9 to scrape off the raw materials remaining on the extrusion roller shafts 9. The two supporting brackets 44 play a fixing role to ensure that the dust cleaning mechanism 46 can perform secondary cleaning on the extrusion roller shafts 9.

[0065] In order to enable the cleaning brush 55 to continuously abut against the corresponding spherical groove 10 on the extrusion roller shaft 9, the following features are specifically set:

[0066] The dust cleaning mechanism 46 includes a number of connecting belt pulleys 47, a number of driving bevel gears 48, a number of driven bevel gears 49, a number of positioning sleeves 51, a number of positioning springs 52 and a number of positioning pin shafts 53. The number of connecting belt pulleys 47 are evenly arranged at equal intervals along the supporting bracket 44. Adjacent two connecting belt pulleys 47 are connected by belt drive. The output end of the third motor 43 is key-connected to the connecting belt pulley 47 at the end. The driving bevel gear 48 is arranged at the upper end of the supporting bracket 44 and the driving bevel gear 48 at the end is fixedly connected to the connecting belt pulley 47. The driven bevel gear 49 is arranged beside the driving bevel gear 48 and meshes with the driving bevel gear 48. The number of positioning sleeves 51 are coaxially arranged with the number of driven bevel gears 49 respectively. The number of positioning sleeves 51 are fixedly connected to the supporting bracket 44 respectively. The number of positioning pin shafts 53 are slidably connected to the number of positioning sleeves 51 respectively. One end of the number of positioning springs 52 abuts against the number of positioning sleeves 51, and the other end abuts against one end of the number of positioning pin shafts 53. The other end of the number of positioning pin shafts 53 is coaxially arranged with the number of driven bevel gears 49 and is fixedly connected to the cleaning brush 55. When the device operates, the third motor 43 starts to drive the connecting belt pulley 47 connected to it to rotate. The number of connecting belt pulleys 47 are connected by belts and start to rotate at the same time. The rotation of the connecting belt pulley 47 drives the driving bevel gear 48 connected to it to rotate. The rotation of the driving bevel gear 48 drives the driven bevel gear 49 meshing with it to rotate. The rotation of the driven bevel gear 49 drives the positioning pin shaft 53 connected to it to rotate. The rotation of the positioning pin shaft 53 drives the cleaning brush 55 connected to it to rotate. During this process, the positioning spring 52 can push the positioning pin shaft 53 and finally drive the cleaning brush 55 to continuously abut against the corresponding spherical groove 10 on the extrusion roller shaft 9.

[0067] In order to ensure that the positioning pin shaft 53 can move along the axial direction while rotating, the following features are specifically set:

[0068] The dust cleaning mechanism 46 further includes a plurality of positioning snap rings 54. Positioning groove holes 50 are formed on a plurality of driven bevel gears 49. The plurality of positioning snap rings 54 are respectively key-connected to a plurality of positioning pin shafts 53 and are slidably connected to the positioning groove holes 50. When the device operates, in order to prevent the positioning pin shafts 53 from slipping relative to the driven bevel gears 49, the positioning snap rings 54 can ensure that the positioning pin shafts 53 can move along the axial direction while rotating.

[0069] The working principle of this device is as follows: When the device operates, raw materials are poured from the upper end of the feeding cylinder 1. Subsequently, when the first motor 6 starts, it drives two stirring roller shafts 16 and two extrusion roller shafts 9 to rotate. During this process, the rotation of the two stirring roller shafts 16 can prevent the raw materials from clogging in the feeding cylinder 1. Subsequently, the falling raw materials are compacted and formed in the spherical grooves 10 under the extrusion of the two extrusion roller shafts 9. At this time, the raw materials are divided into debris powder and spherical coarse material blocks. The extruded raw materials continue to fall and enter the reaction cylinder 2 for screening.

[0070] In order to prevent the raw materials from being compacted on the outer side walls of the two extrusion roller shafts 9, two scraping arc plates 45 continuously press against the lower ends of the two extrusion roller shafts 9 to scrape off the raw materials remaining on the extrusion roller shafts 9. During this process, when the third motor 43 starts, it drives a plurality of cleaning brushes 55 to rotate. A plurality of positioning springs 52 can push a plurality of positioning pin shafts 53 and finally drive a plurality of cleaning brushes 55 to continuously press against the corresponding spherical grooves 10 on the extrusion roller shafts 9. The plurality of cleaning brushes 55 can clean the raw materials in the spherical grooves 10.

[0071] In the reaction cylinder 2, the spherical coarse material blocks and the debris powder will move along the first arc-shaped baffle 32. And part of the debris powder will be separated under the action of the screening mechanism 26. At this time, the driving roller shaft 27 located above rotates in the clockwise direction, and the driving roller shaft 27 located below rotates in the counterclockwise direction. During this process, the debris powder and the spherical coarse material blocks can be separated through the strip-shaped filter holes 29. The debris powder will enter the suction machine 41 through the lower end of the first arc-shaped baffle 32 and the upper end of the second arc-shaped baffle 33 under the combined action of the exhaust fan 40 and the suction machine 41. And the spherical coarse material blocks flow out of the reaction cylinder 2 through the upper end of the second arc-shaped baffle 33 and are collected through the discharge port 3. The flow direction of the air flow refers to Figure 5 the arrow directions in

[0072] It should be noted that the air flow blown out by the exhaust fan 40 will discharge the debris powder sliding down from the second arc-shaped baffle 33 through the second dust guide plate 37 from the dust discharge port 4.

[0073] The above embodiments merely represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention shall be subject to the appended claims.
