Description

Technical Field

[0001] The invention relates to the technical field of alloy pretreatment, in particular to an alloy pretreatment device capable of uniformly mixing. Background Art

[0002] Alloy powder pretreatment is a crucial step in the production and processing of alloy materials. Uniform mixing of alloy powders directly impacts the performance, quality, and production efficiency of subsequent alloy materials. However, existing alloy powder pretreatment technologies still face several challenges that need to be addressed.

[0003] Traditional alloy powder mixing devices often use simple stirring methods, such as single rotational stirring or vibration stirring. While these methods can achieve a certain degree of alloy powder mixing, they often suffer from low mixing efficiency and uneven mixing. This is particularly true when processing mixtures containing alloy powders of varying particle sizes, densities, or shapes. Traditional stirring methods struggle to ensure adequate contact and uniform dispersion of the various powder components, thus impacting the properties of the final alloy.

[0004] Furthermore, alloy powders tend to agglomerate during storage and transportation. These agglomerated alloy powders are difficult to disperse effectively during the subsequent mixing process, which not only reduces mixing efficiency but can also lead to defects such as component segregation and structural inhomogeneity within the alloy material, seriously affecting the performance and service life of the alloy material.

[0005] Screening is an essential step in alloy powder pretreatment. It removes impurities and large particles from the powder, ensuring its purity and particle size distribution. However, traditional screening devices often suffer from low screening efficiency and easy clogging of the screen.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0024] For examples, see Figure 1 - Figure 7 , a uniformly mixed alloy pretreatment device, comprising a mixing mechanism 1, which includes a shell 10, and a rotating bar 11 vertically arranged inside the shell 10, a mixing rod 12 is fixedly connected to the outer side of the lower end of the rotating bar 11, a driving component for driving the mixing rod 12 to rotate is arranged above the rotating bar 11, the top of the rotating bar 11 is fixedly connected to the middle part of the bottom side of the adjusting disk 21, and a lifting component for driving the mixing rod 12 to move up and down is arranged above the adjusting disk 21, and a pretreatment mechanism 3 is arranged above one side of the mixing mechanism 1; the pretreatment mechanism 3 includes a screening box 31 arranged on one side of the shell 10, and a net bag 33 inside the screening box 31 for screening alloy powder, a vibration component for driving the net bag 33 to vibrate, and a crushing component for crushing the alloy agglomerated inside the net bag 33 are respectively arranged above and below the net bag 33, a discharge pipe 51 is fixedly installed at the bottom end of the screening box 31, and a control component for controlling the feeding speed is arranged inside the discharge pipe 51.

[0025] In this embodiment, the driving assembly can drive the rotating bar 11 to rotate, thereby driving the mixing rod 12 to rotate, mixing and stirring the alloy powder in the housing 10. During the rotation of the rotating bar 11, the adjusting disk 21 can be driven to rotate. The lifting assembly can drive the rotating bar 11 to move up and down, thereby adjusting the stirring position of the mixing rod 12 in the housing 10, further improving the mixing efficiency of the alloy powder. While the adjusting disk 21 rotates up and down, the vibration assembly can drive the net bag 33 to vibrate in the screening box 31, thereby improving the screening effect of the net bag 33 on the alloy powder. At the same time, the connecting bar 34 in the vibration mechanism can drive the vibration assembly to automatically break up the alloy agglomerated inside the net bag 33. During the operation of the vibration assembly, it can drive the control assembly to automatically control the discharge amount of the discharge pipe 51, so that the screened alloy powder is evenly added to the housing 10, avoiding the accumulation of alloy powder in the housing 10 and affecting the uniform mixing effect.

[0026] Furthermore, the driving assembly includes a driving column 13 and a driving motor 16. The upper end of the driving column 13 passes through the middle of the second gear 15 and is welded to the second gear 15. The driving column 13 is rotatably connected to the middle of the top of the shell 10 through a bearing. The shaft end of the driving motor 16 is fixedly connected to the middle of the bottom side of the first gear 17. The first gear 17 is meshed with the second gear 15. The driving motor 16 is fixedly connected to one side of the upper surface of the shell 10. A slide groove 14 is vertically penetrated through the middle of the driving column 13. The rotating bar 11 is slidably connected to the slide groove 14. The slide groove 14 is cross-shaped. The size of the rotating bar 11 matches that of the slide groove 14. The mixing rods 12 are equidistantly distributed at one end of the rotating bar 11 on the inner side of the shell 10, and the size of the mixing rod 12 matches that of the shell 10.

[0027] In this embodiment, when the alloy powder in the shell 10 needs to be evenly mixed, the corresponding controller controls the drive motor 16 to work, which can drive the first gear 17 to rotate. The first gear 17 engages with the second gear 15. During the rotation of the first gear 17, the drive column 13 in the middle of the second gear 15 can be driven to rotate at the top of the shell 10. Since the slide groove 14 in the middle of the drive column 13 is cross-shaped and matches the size of the rotating bar 11, the rotating bar 11 can be limited, so that the driving column 13 can drive the rotating bar 11 to rotate synchronously during the rotation of the driving column 13, thereby driving the mixing rod 12 at the lower end of the rotating bar 11 to rotate in the shell 10 and mix and stir the alloy powder.

[0028] Furthermore, the lifting assembly includes an adjusting column 23 and a limiting rod 25. The adjusting column 23 is placed in the middle above the adjusting disk 21. The bottom end of the limiting rod 25 is welded to one side of the upper surface of the adjusting disk 21. A limiting groove 24 is provided on the outer side of the adjusting column 23. The end of the limiting rod 25 away from the adjusting disk 21 is slidably connected to the limiting groove 24. The limiting groove 24 is wavy, and the limiting rod 25 is in an inverted L-shape. An inverted L-shaped bracket 22 is welded to the end of the upper surface of the shell 10 close to the drive motor 16, and the top of the adjusting column 23 is welded to the inner wall of the top of the bracket 22.

[0029] In this embodiment, since the middle part of the bottom side of the adjusting disk 21 is fixedly connected to the top of the rotating bar 11, the driving column 13 drives the rotating bar 11 to rotate, and at the same time, can drive the adjusting disk 21 and the limiting rod 25 welded on the upper surface of the adjusting disk 21 to rotate. Since the adjusting column 23 is fixed above the shell 10 through the bracket 22, during the rotation of the adjusting disk 21, the end of the limiting rod 25 away from the adjusting disk 21 can slide in the limiting groove 24 on the outside of the adjusting column 23. Since the limiting groove 24 is wavy, the limiting rod 25 can drive the adjusting disk 21 to move back and forth up and down during the sliding process in the limiting groove 24, thereby driving the mixing rod 12 at the lower end of the rotating bar 11 to move back and forth up and down in the shell 10, further improving the mixing efficiency of the mixing rod 12 for the alloy powder.

[0030] It is worth noting that the vibration assembly includes an L-shaped connecting strip 34, one bent end of the connecting strip 34 is placed in the screening box 31 and welded to one end of the upper surface of the fixed frame 32, the open end of the net bag 33 is fixedly connected to the bottom side of the fixed frame 32, and a slot 35 is provided at the end of the connecting strip 34 away from the fixed frame 32. The slot 35 at one end of the connecting strip 34 is rotatably connected to the outer side of the adjusting disk 21, and guide grooves 36 are provided through the front and rear ends of the upper surface of the fixed frame 32. Guide rods 37 are vertically fixedly installed on the inner walls on the front and rear sides of the screening box 31, and the guide rods 37 on the front and rear sides of the screening box 31 are slidably connected to the guide grooves 36 on the front and rear sides of the fixed frame 32.

[0031] In this embodiment, the slot 35 at one end of the connecting bar 34 is rotatably connected to the outer side of the adjusting disk 21. During the up and down rotation of the adjusting disk 21, the connecting bar 34 can be driven to move up and down. The guide rods 37 on the front and rear sides of the screening box 31 are slidably connected to the guide grooves 36 on the front and rear sides of the fixed frame 32. During the up and down movement of the connecting bar 34, the fixed frame 32 can be driven to move up and down in the screening box 31, thereby driving the net bag 33 to vibrate, and the alloy powder to be processed is introduced into the net bag 33, which can effectively screen the agglomerated alloy powder.

[0032] It is worth noting that the crushing assembly includes an extrusion plate 44, a driving bar 41 and an adjusting plate 46. The extrusion plate 44 is vertically arranged at the bottom of the screen box 31. The driving bar 41 is vertically welded to the bottom side of the connecting bar 34, and the driving bar 41 is placed between the screen box 31 and the shell 10. A positioning plate 43 is vertically fixedly installed at the bottom of the screen box 31. The positioning plate 43 is aligned with the extrusion plate 44, and the bottom end of the net bag 33 is placed between the positioning plate 43 and the extrusion plate 44. The extrusion plate 44 is away from the net bag 33. Two groups of connecting rods 45 are fixedly installed horizontally on one side. The end of the connecting rod 45 away from the extrusion plate 44 passes through the screening box 31 and is fixedly connected to the adjustment plate 46. A trapezoidal block 42 is welded to the side of the driving bar 41 close to the screening box 31. The inclined surface of the trapezoidal block 42 is movably connected to the adjustment plate 46. Two groups of springs 47 are provided on the side of the adjustment plate 46 close to the screening box 31. The spring 47 is sleeved on the outside of the connecting rod 45, and the two ends of the spring 47 are fixedly connected to the outside of the screening box 31 and the adjustment plate 46 respectively.

[0033] The spring 47 is provided on the side of the adjusting plate 46 close to the screening box 31, and the connecting rod 45 can pull the extrusion plate 44 away from the positioning plate 43, thereby automatically releasing the extrusion of the net bag 33 and avoiding affecting the vibration of the net bag 33.

[0034] It is worth mentioning that the control component includes a control panel 53, and a funnel-shaped discharge trough 52 is provided on the inner wall of the bottom end of the screening box 31. The discharge end of the discharge trough 52 is connected with the feed end of the discharge pipe 51, and the discharge end of the discharge pipe 51 is connected with the upper end inside the shell 10. The control panel 53 is placed at the upper end inside the discharge pipe 51. A control rod 54 is horizontally passed through and fixedly installed in the middle of the control panel 53. The control rod 54 is rotatably connected to the inner wall of the discharge pipe 51 through a bearing. A third gear 55 is fixedly installed on the end of the control rod 54 away from the control panel 53, and a rack 56 is vertically welded on the front side of the bottom end of the drive bar 41, and the rack 56 is engaged with the third gear 55.

[0035] In this embodiment, a funnel-shaped discharge chute 52 is provided at the bottom of the screening box 31. The screened and crushed alloy powder can be introduced into the housing 10 through the discharge pipe 51 at the bottom of the screening box 31 for mixing. When the driving bar 41 drives the trapezoidal block 42 to move downward, it can also drive the rack 56 to move downward. The rack 56 engages with the third gear 55 at one end of the control rod 54. When the rack 56 moves downward, it can drive the third gear 55 to rotate. The control rod 54 can drive the control plate 53 to rotate to a horizontal state in the discharge pipe 51, closing the discharge pipe 51. When the driving bar 41 moves upward, the rack 56 can drive the third gear 55 to rotate in the opposite direction. The control rod 54 drives the control plate 53 to rotate to a vertical state, thereby automatically controlling the opening and closing of the discharge pipe 51, so that the screened alloy powder is evenly added to the housing 10, avoiding the accumulation of alloy powder in the housing 10 and affecting the uniform mixing effect.

[0036] Working principle: When the alloy powder in the shell 10 needs to be evenly mixed, the corresponding controller controls the driving motor 16 to work, which can drive the first gear 17 to rotate. The first gear 17 is engaged with the second gear 15. During the rotation of the first gear 17, the driving column 13 in the middle of the second gear 15 can be driven to rotate at the top of the shell 10. Since the slide groove 14 in the middle of the driving column 13 is cross-shaped and matches the size of the rotating bar 11, the rotating bar 11 can be limited so that the driving column 13 can drive the rotating bar 11 to rotate synchronously during the rotation of the driving column 13, thereby driving the mixing rod 12 at the lower end of the rotating bar 11 to rotate in the shell 10 and mix and stir the alloy powder. Since the middle of the bottom side of the adjusting disk 21 is aligned with the rotating bar The top of 11 is fixedly connected, and the driving column 13 drives the rotating bar 11 to rotate, and can drive the adjusting disk 21 and the limiting rod 25 welded on the upper surface of the adjusting disk 21 to rotate. Since the adjusting column 23 is fixed to the upper part of the shell 10 by the bracket 22, during the rotation of the adjusting disk 21, the end of the limiting rod 25 away from the adjusting disk 21 can slide in the limiting groove 24 on the outer side of the adjusting column 23. Since the limiting groove 24 is wavy, the limiting rod 25 can drive the adjusting disk 21 to move back and forth when sliding in the limiting groove 24, thereby driving the mixing rod 12 at the lower end of the rotating bar 11 to move back and forth in the shell 10, further improving the mixing efficiency of the mixing rod 12 for the alloy powder. The outer side of the section disc 21 is rotatably connected. During the up and down rotation of the adjusting disc 21, the connecting bar 34 can be driven to move up and down. The guide rods 37 on the front and rear sides of the screening box 31 are slidably connected with the guide grooves 36 on the front and rear sides of the fixed frame 32. During the up and down movement of the connecting bar 34, the fixed frame 32 can be driven to move up and down in the screening box 31, thereby driving the net bag 33 to vibrate, and the alloy powder to be processed is introduced into the net bag 33, which can effectively screen the agglomerated alloy powder. While the connecting bar 34 drives the net bag 33 to move up and down, it can also drive the trapezoidal block 42 on the outer side of the driving bar 41 to move up and down. Since the inclined surface of the trapezoidal block 42 is movably connected to the adjusting plate 46, when the trapezoidal block 42 moves downward, it can push the adjusting plate 46 close to the screening The box 31 can push the extrusion plate 44 close to the positioning plate 43 through the connecting rod 45. Since the lower end of the net bag 33 is placed between the positioning plate 43 and the extrusion plate 44, the extrusion plate 44 and the positioning plate 43 can automatically crush the alloy powder agglomerated inside the net bag 33. When the driving bar 41 drives the trapezoidal block 42 to move upward and reset, the extrusion of the adjustment plate 46 is released. A spring 47 is provided on the side of the adjustment plate 46 close to the screening box 31. The elastic force of the spring 47 can push the adjustment plate 46 away from the screening box 31, and the connecting rod 45 can pull the extrusion plate 44 away from the positioning plate 43, thereby automatically releasing the extrusion of the net bag 33 to avoid affecting the vibration of the net bag 33. A funnel-shaped discharge chute 52 is provided at the bottom end of the screening box 31.The discharge pipe 51 at the bottom of the screening box 31 can introduce the sieved and crushed alloy powder into the housing 10 for mixing. When the driving bar 41 drives the trapezoidal block 42 downward, it can also drive the rack 56 downward. The rack 56 engages with the third gear 55 at one end of the control rod 54. When the rack 56 moves downward, it can drive the third gear 55 to rotate. The control rod 54 can drive the control plate 53 to rotate to a horizontal state in the discharge pipe 51, closing the discharge pipe 51. When the driving bar 41 moves upward, the rack 56 can drive the third gear 55 to rotate in the opposite direction. The control rod 54 drives the control plate 53 to rotate to a vertical state, thereby automatically controlling the opening and closing of the discharge pipe 51, so that the sieved alloy powder is evenly added to the housing 10, preventing the alloy powder from accumulating in the housing 10 and affecting the uniform mixing effect.
