Abstract
Description
Technical Field
[0001] This invention relates to the field of alloy metal preparation technology, specifically to a mixing and stirring device for alloy metal preparation. Background Technology
[0002] An alloy is a solid product with metallic properties obtained by mixing and melting one metal with one or more other metals or non-metals, then cooling and solidifying it. When mixing multiple metals and additives, a stirring device is required. Current methods involve directly pouring the various metals and additives into a stirring tank and then heating them to melt them into a molten metal. However, because each metal and additive is piled up separately, mixing becomes very difficult. Traditional mechanical stirring methods easily cause centrifugal separation in the alloy solution, preventing the various metals and additives from mixing effectively. This exacerbates the inhomogeneity of the solidification process. The higher the rotation speed, the more pronounced this separation becomes, resulting in poor mixing and uneven element distribution in the alloy molten metal, thus affecting the quality of the alloy.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages:
[0016] 1. Open the sealing cap at the top of the feeding cylinder, add metal material into the mixing tank through the gap between the dispersion box and the feeding cylinder, and then pour a small amount of metal material and additives into the dispersion box. Then fix the sealing cap at the top of the feeding cylinder. At this time, the output shaft of the servo motor rotates forward and reverse alternately, thereby driving the mixing tank to swing back and forth. At the same time, the mixing tank drives the feeding cylinder to swing back and forth, and the feeding cylinder drives the dispersion component to swing back and forth. Meanwhile, the gears in the dispersion component roll along the sector tooth plate. Through the cooperation of the rotary drive mechanism and the feeding mechanism, the dispersion box shakes up and down while swinging back and forth, preventing the metal material or additives from clogging the feeding hole at the bottom of the dispersion box. This allows the metal material and additives in the dispersion box to be evenly sprinkled into the mixing tank. Then, by cooperating with the set mixing component, the alloy metal solution and additives can be evenly mixed.
[0017] 2. The rotating shaft drives the spiral plate, stirring paddle, reinforcing arm, and stirring plate to stir the molten metal. The spiral plate causes the molten metal in the center of the mixing tank to surge upwards, while the stirring paddle and stirring plate ensure good mixing of the alloy molten metal, preventing centrifugal separation of the metal materials according to their mass. The reciprocating oscillation of the mixing tank also causes the molten metal inside to slosh around, further enhancing the mixing effect with the stirring components. This results in a uniform distribution of elements in the molten metal. When unloading is required after mixing, the sealing plug is removed from the discharge pipe. Simultaneously, the stirring components rotate, causing the stirring plate to rotate along the sidewalls and bottom of the mixing tank, scraping off the molten metal adsorbed on the sidewalls and bottom, allowing the molten metal inside the mixing tank to be discharged smoothly through the discharge pipe.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] Please see Figures 1 to 8This invention provides a technical solution: a mixing and stirring device for alloy metal preparation, comprising a device support frame 1 and a stirring tank 2. The stirring tank 2 is mounted on the device support frame 1. Sector-shaped guide rails 11 are symmetrically mounted on the bottom inner side of the device support frame 1. Sector-shaped toothed plates 12 are fixedly mounted at the ends of the two side plates of the device support frame 1. Connecting shafts 21 for rotation are symmetrically mounted on the sides of the stirring tank 2. The connecting shafts 21 are rotatably connected to the side plates of the device support frame 1. One of the connecting shafts 21 is fixedly connected to the output shaft of a servo motor. The servo motor is bolted to one side plate of the device support frame 1. The output shaft rotates alternately in both forward and reverse directions, driving the connecting shaft 21 to rotate. The connecting shaft 21 causes the mixing tank 2 to swing back and forth, thereby causing the alloy metal solution inside the mixing tank 2 to sway back and forth for mixing. The lower end of the mixing tank 2 is symmetrically fixed with a sliding plate 22 for limiting. The mixing tank 2 is installed between the two side plates of the device support frame 1. A heating component is embedded inside the mixing tank 2. The sliding plate 22 is slidably connected to the guide groove at the upper end of the fan-shaped guide rail 11. The inner cavity of the mixing tank 2 is equipped with a positioning ring 23 and a stirring component for stirring. A discharge pipe is welded through the lower end of the mixing tank 2, and a sealing plug is fixedly connected to the lower end of the discharge pipe by screws.
[0029] A feeding cylinder 4 is fixedly connected to the upper end of the mixing tank 2. The feeding cylinder 4 is a cylinder with openings at both the upper and lower ends. A sealing cover 41 is installed at the upper end of the feeding cylinder 4. A dispersing component for feeding is installed on the feeding cylinder 4. Both ends of the dispersing component penetrate through the side wall of the feeding cylinder 4 and extend to the outside.
[0030] During operation, the sealing cap 41 at the upper end of the feeding cylinder 4 is opened, and metal material is added into the mixing tank 2 through the gap between the dispersion box 6 and the feeding cylinder 4. Then, a small amount of metal material and additives are poured into the dispersion box 6. The sealing cap 41 is then fixed to the upper end of the feeding cylinder 4 to seal it. The metal material in the mixing tank 2 is heated to a solution state by the heating component. The output shaft of the servo motor rotates alternately in both forward and reverse directions, driving the connecting shaft 21 to rotate back and forth. The connecting shaft 21 drives the mixing tank 2 to swing back and forth. The mixing tank 2 drives the slide plate 22 to slide back and forth along the fan-shaped guide rail 11, thereby enabling the mixing tank 2 to move stably. The mixing tank 2 drives the feeding cylinder 4 to swing back and forth, and the feeding cylinder 4 drives the dispersing component to swing back and forth. At the same time, the gear 53 in the dispersing component rolls along the sector tooth plate 12. The gear 53 drives the loop limit frame 5 to rotate back and forth through the rotating rod 51. Through the cooperation of the rotation drive mechanism and the spreading mechanism, the dispersing box 6 shakes up and down while swinging back and forth, preventing the metal material or additives from clogging the spreading hole at the bottom of the dispersing box 6. This allows the metal material and additives in the dispersing box 6 to be evenly spread into the mixing tank 2. Then, by cooperating with the set mixing component, the alloy metal solution and additives can be evenly mixed.
[0031] The motor shaft drives the rotating shaft 3 to rotate, which in turn drives the spiral plate 31, stirring paddle 32, reinforcing arm 33, and stirring plate 35 to rotate. The spiral plate 31, stirring paddle 32, and stirring plate 35 work together to stir the molten metal. The spiral plate 31 causes the molten metal in the center of the inner cavity of the mixing tank 2 to surge upwards, while the stirring paddle 32 and stirring plate 35 ensure good mixing of the alloy metal solution, preventing centrifugal separation of the metal materials according to their mass. Furthermore, the reciprocating oscillation of the mixing tank 2 further... The alloy metal solution inside the mixing tank 2 sloshes back and forth, and in conjunction with the stirring assembly, it can effectively mix and stir the alloy metal solution, resulting in a uniform distribution of elements in the alloy metal solution and good performance. When the alloy metal solution needs to be unloaded after mixing, the sealing plug is removed from the discharge pipe, and at the same time the stirring assembly rotates, causing the stirring plate 35 to rotate along the side wall and bottom of the inner cavity of the mixing tank 2, thereby scraping off the alloy metal solution adsorbed on the side wall and bottom of the inner cavity of the mixing tank 2, so that the alloy metal solution inside the mixing tank 2 can be discharged well along the discharge pipe.
[0032] The mixing assembly includes: a rotating shaft 3, a spiral plate 31, a stirring paddle 32, reinforcing arms 33, a limiting seat 34, and a stirring plate 35. The rotating shaft 3 is rotatably connected to the inner cavity of the mixing tank 2. The lower end of the rotating shaft 3 is fixedly connected to the motor shaft, and the motor shaft is rotatably connected to the bottom of the mixing tank 2. The spiral plate 31, stirring paddle 32, and stirring plate 35 for stirring are installed on the rotating shaft 3. The spiral plate 31 and stirring paddle 32 are spirally distributed on the side of the rotating shaft 3. Multiple reinforcing arms 33 are installed in a circumferential array on the upper end of the rotating shaft 3. A limiting seat 34 is fixedly installed on the end of each reinforcing arm 33 away from the rotating shaft 3. A stirring plate is fixedly connected to the lower end of each limiting seat 34. 35. The motor shaft drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the spiral plate 31, the stirring paddle 32, the reinforcing arm 33, and the stirring plate 35 to rotate. The spiral plate 31 causes the central metal solution in the inner cavity of the mixing tank 2 to surge upward. At the same time, the stirring paddle 32 and the stirring plate 35 stir the solution, ensuring that the alloy metal solution is well mixed and preventing the separation of metal materials according to their mass. In addition, the reciprocating oscillation of the mixing tank 2 causes the alloy metal solution in the inner cavity of the mixing tank 2 to sway back and forth. Combined with the stirring components, the alloy metal solution can be well mixed and stirred, resulting in a uniform distribution of elements in the alloy metal solution and a good effect.
[0033] The stirring paddle 32 is integrally formed with one end of a rectangular plate and a round rod. The rectangular plate has through holes at equal intervals on its side. The end of the round rod away from the rectangular plate is fixedly connected to the rotating shaft 3. When the stirring paddle 32 stirs the alloy metal solution, it stirs through the rectangular plate, pushes a part of the metal solution, and passes through the through holes to disperse and stir the metal solution, thereby effectively mixing the alloy metal solution.
[0034] One side of the limiting bracket 34 is sloped, and a slot is provided on the slope of the limiting bracket 34. The positioning ring 23 is engaged with the slot, and the limiting bracket 34 is rotatably connected to the positioning ring 23. When the rotating shaft 3 rotates, it drives the reinforcing arm 33 to rotate. The reinforcing arm 33 drives the limiting bracket 34 to rotate along the positioning ring 23, so that the rotating shaft 3 can rotate stably, thereby enabling the stirring assembly to stably mix and stir the alloy metal solution.
[0035] The stirring plate 35 slides in contact with the side wall and bottom of the inner cavity of the mixing tank 2. The lower end of the stirring plate 35 is fixedly connected to the side of the lower end of the rotating shaft 3. The stirring plate 35 stirs the metal solution on the side wall and bottom of the inner cavity of the mixing tank 2, preventing some metal solution from adsorbing on the mixing tank 2, so that the metal solution can be mixed evenly. When the alloy metal solution needs to be unloaded after mixing, the sealing plug is removed from the discharge pipe. At the same time, the stirring assembly rotates, so that the stirring plate 35 rotates along the side wall and bottom of the inner cavity of the mixing tank 2, thereby scraping off the alloy metal solution adsorbed on the side wall and bottom of the inner cavity of the mixing tank 2, so that the alloy metal solution in the inner cavity of the mixing tank 2 can be discharged well along the discharge pipe.
[0036] The dispersing assembly consists of a rotary drive mechanism and a feeding mechanism. The rotary drive mechanism includes a loop-shaped limiting frame 5, rotating rods 51, limiting rings 52, and gears 53. A sleeve 44 is welded through the side wall of the feeding cylinder 4. The loop-shaped limiting frame 5 is installed inside the feeding cylinder 4. Rotating rods 51 are symmetrically installed on both sides of the loop-shaped limiting frame 5. The ends of the two rotating rods 51 away from the loop-shaped limiting frame 5 pass through the sleeve 44 and extend to the outside. Gears 53 are fixedly installed on the ends of the two rotating rods 51 away from the loop-shaped limiting frame 5. Two limiting rings 52 are fixedly installed on the two rotating rods 51. The two limiting rings 52 are located at both ends of the sleeve 44, and the limiting rings 52 are fixed to the sleeve 44. Rotary contact, the rotating rod 51 is rotatably connected to the inner cavity of the sleeve 44. When the mixing tank 2 swings back and forth, it drives the feeding cylinder 4 to swing back and forth. The feeding cylinder 4 drives the rotary drive mechanism to swing back and forth. The gear 53 is set above the sector tooth plate 12 and meshes with the sector tooth plate 12. A protective shell is provided on the side of the gear 53 and the sector tooth plate 12. The protective shell is installed on the upper end of the side plate of the device support frame 1. The rotating rod 51 drives the gear 53 to roll along the sector tooth plate 12, so that the rotating rod 51 rotates while swinging back and forth. The rotating rod 51 drives the loop limit frame 5 to rotate, so that the loop limit frame 5 rotates at a certain angle while swinging back and forth with the feeding cylinder 4.
[0037] A curved panel 42 is fixedly connected to the lower end of the sealing cover 41. Multiple semi-cylindrical blocks 43 are welded at equal intervals on the inner curved surface of the curved panel 42. The material spreading mechanism includes: a dispersion box 6, an extrusion bracket 61, a roller 62, a guide slide rod 63, and a return spring 64. The dispersion box 6 is inserted through the inner side of the U-shaped limit frame 5. Multiple material spreading holes are opened at equal intervals at the bottom of the dispersion box 6. The upper end of the dispersion box 6 has a protruding edge. An extrusion bracket 61 is symmetrically welded to the upper end of the edge. The upper ends of the two extrusion brackets 61 are rotatably connected to the roller 62 through a pin. A pair of guide slide rods 63 are symmetrically welded to the lower end of the edge. A return spring 64 is sleeved on the guide slide rod 63. The lower end of the return spring 64 is inserted into the U-shaped limit frame 5. The upper end of the return spring 64 is inserted into the edge of the upper end of the dispersion box 6. The return spring 64 applies elastic force to the edge.
[0038] Roller 62 is located at the lower end of curved panel 42, and roller 62 rolls in contact with curved panel 42 and semi-cylindrical block 43 respectively. The lower end of guide slide rod 63 passes through the loop-shaped limiting frame 5 and is fixedly connected to the annular plate. The annular plate is located at the lower end of loop-shaped limiting frame 5. Guide slide rod 63 is slidably connected to loop-shaped limiting frame 5. When loop-shaped limiting frame 5 rotates, it drives dispersion box 6 to rotate. Dispersion box 6 drives extrusion bracket 61 to rotate. Extrusion bracket 61 drives roller 62 to be fixed along curved panel 42. When roller 62 rolls along semi-cylindrical block 43, semi-cylindrical block 43 pushes roller 62 downward. 2. The dispersion box 6 is driven to move downward along the loop-shaped limit frame 5 by the extrusion bracket 61. At the same time, the dispersion box 6 extrudes the return spring 64. When the roller 62 separates from the semi-cylindrical block 43, the dispersion box 6 moves upward under the action of the return spring 64, so that the metal material or additive in the dispersion box 6 can be evenly sprinkled into the mixing tank 2. The set stirring components can make the alloy metal and additives evenly mixed. At the same time, as the dispersion box 6 swings back and forth and shakes up and down, the metal material or additive in the dispersion box 6 is continuously sprinkled down along the sprinkling hole, preventing the sprinkling hole from being blocked.
