Description

Technical Field

[0001] The invention belongs to the technical field of stirring equipment, in particular to an argon-filled stirring device for an alloy melting furnace. Background Art

[0002] An alloy melting furnace is a type of industrial equipment used to melt and refine metal alloys. These furnaces are designed to heat raw metals to their melting point in order to fuse different metallic elements together to form alloys with specific chemical and physical properties. Alloy melting furnaces can be used in a variety of industries, including manufacturing, metal processing, foundry, and mining.

[0003] In actual applications, there are different types and technologies of alloy melting furnaces, such as resistance furnaces, induction furnaces, gas furnaces or electric arc furnaces. They may use electricity, fuel or natural gas as heat sources. During the melting process, the furnace is usually equipped with advanced control systems to ensure precise temperature control. It may also be equipped with a stirring system and a gas purification device to remove impurities and protect the metal from oxidation. For example, argon is injected into the alloy liquid. Argon is an inert gas that does not chemically react with other elements in the alloy during the alloy melting process. At the same time, it can effectively isolate oxygen and prevent the alloy liquid from being oxidized at high temperatures.

[0004] Most alloy melting furnaces in the prior art stir the alloy liquid in the stirring drum through a stirring head. This stirring method cannot ensure uniform stirring of the alloy liquid.

The first abutment plate 1416 rotates against the original position of the stirring drum 4. The first stirring blade 1415 rotates through the first stirring shaft 1413.

[0031] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the first stirring assembly 14 includes a rotating ring 1411, a clamping block 1412 is fixedly connected to the interior of the rotating ring 1411, a first stirring shaft 1413 is fixedly connected to the bottom of the clamping block 1412, a stirring frame 1414 is fixedly connected to the outside of the first stirring shaft 1413 in an annular shape at equal intervals, a first stirring blade 1415 is fixedly connected to one side of the stirring frame 1414 in a linear shape at equal intervals, and a first stop plate 1416 is fixedly connected to the bottom end of the first stirring shaft 1413;

When the driving plate 13 rotates, the rotating ring 1411 will not rotate. When the rotating motor 15 drives the first stirring shaft 1413 to rotate, the first stirring shaft 1413 can drive the stirring frame 1414 and the first stirring blade 1415 to rotate, so that the stirring frame 1414 and the first stirring blade 1415 can stir the alloy liquid at the same time, and the first stirring shaft 1413 is limited to rotate by the stirring drum 4, and the first abutment plate 1416 movably connects the first stirring shaft 1413 with the stirring drum 4. The alloy liquid can be blocked by the first abutment plate 1416 to prevent the alloy liquid from seeping into the bottom of the stirring drum 4, and the first stirring component 14 will not collide with the second stirring component 21 during rotation.

[0034] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the driving component 17 includes a first driving gear 1711, a driving shaft 1712 is fixedly connected to the interior of the first driving gear 1711, and a second driving gear 1713 is fixedly connected to the bottom end of the driving shaft 1712;

[0035] The outer edge of the first driving gear 1711 meshes with the connecting gear 11, the bottom of the first driving gear 1711 abuts against the top of the driving plate 13, the outer portion of the driving shaft 1712 is movably connected to the inner portion of the driving plate 13, the top of the second driving gear 1713 abuts against the bottom of the driving plate 13, and the outer edge of the second driving gear 1713 meshes with the driven gear 18;

[0036] The above solution is adopted: the driving shaft 1712 is limited and fixed by the driving plate 13, the outer part of the driving shaft 1712 is movably connected to the inner part of the driving plate 13, the driving shaft 1712 is rotated due to the engagement of the first driving gear 1711 with the connecting gear 11, and the driving shaft 1712 drives the second driving gear 1713 to rotate, and the second driving gear 1713 and the first driving gear 1711 rotate synchronously and in the same direction. In the process of the second driving gear 1713 rotating synchronously with the first driving gear 1711 through the driving shaft 1712, the driven gear 18 is engaged with the second driving gear 1713, and the driven gear 18 rotates with the driven shaft 19 as the center of the circle.

[0037] like Figure 3 、 Figure 5 、 Figure 6 As shown, the driven assembly 20 includes a driven plate 2011, one end of the driven plate 2011 is fixedly connected to the driven rod 2012, the other end of the driven plate 2011 is fixedly connected to the driven shaft 19, and the top of the driven plate 2011 abuts against the bottom of the driven gear 18;

[0038] The second stirring assembly 21 includes a second stirring shaft 2111, with second stirring blades 2112 fixedly connected to both sides of the second stirring shaft 2111, a second abutment plate 2113 fixedly connected to the bottom end of the second stirring shaft 2111, the top end of the second stirring shaft 2111 is fixedly connected to the driven rod 2012, and the bottom of the second abutment plate 2113 abuts against the stirring drum 4;

[0039] The above scheme is adopted: the driven shaft 19 is limited and fixed by the driving plate 13, the driven shaft 19 supports and fixes the driven plate 2011, and the driven plate 2011 is connected and fixed to the driven rod 2012. When the driven gear 18 rotates by meshing with the second driving gear 1713, the driven gear 18 drives the driven plate 2011 to rotate through the driven shaft 19, and the driven plate 2011 drives the driven rod 2012 to rotate with the driven shaft 19 as the center of the circle. The second stirring assembly 21 is supported by the stirring drum 4, and the driven rod 2012 limits and fixes the second stirring shaft 2111. The driven rod 2012 drives the second stirring shaft 2111 to limit and rotate. The second stirring shaft 2111 drives the second stirring blade 2112 and the second resistance plate 2113 to rotate simultaneously. The second stirring blade 2112 stirs the alloy liquid, so that the alloy liquid is stirred more evenly by the second stirring blade 2112, the first stirring blade 1415 and the stirring frame 1414, so as to facilitate the formation of an alloy with characteristics.

[0040] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, the outer portion of the driving ring 8 is movably connected to the top of the mixing drum 4, the top of the connecting ring 10 is movably connected to the bottom of the driving ring 8, the top of the fixing frame 12 is fixedly connected to the mixing drum 4, the bottom of the rotating motor 15 is fixedly connected to the mixing base 3, and the rotating motor 15 is located in the middle of the interior of the mixing base 3;

[0041] One end of the limiting plate 16 is movably connected to the mixing drum 4. A limiting ring groove 1601 is provided on the inner side of the mixing drum 4, which is adapted to the size of the limiting plate 16. The top of the driven gear 18 abuts against the bottom of the driving plate 13.

[0042] The above solution is adopted: the fixing frame 12 is connected and fixed through the mixing drum 4, and the fixing frame 12 is connected and fixed to the connecting gear 11. When the driving motor 6 drives the driving plate 13 to rotate through the driving shaft 9, the connecting gear 11 is not fixedly connected to the driving plate 13, and the connecting gear 11 does not rotate. The connecting gear 11 remains in a fixed state throughout the entire mixing process. The driving motor 6 is fixedly connected to the top of the mixing drum 4 through the motor frame 7. Argon gas can be filled into the mixing drum 4 through the argon through hole 5. The argon gas can effectively isolate oxygen and prevent the alloy liquid from being oxidized at high temperature.

[0043] The mixing drum 4 is supported by the mixing base 3, and the limiting ring groove 1601 limits the limiting plate 16. When the driving plate 13 drives the limiting plate 16 to rotate through the driving motor 6 and the driving shaft 9, the limiting plate 16 will slide along the limiting ring groove 1601. The second stirring blade 2112, the first stirring blade 1415 and the stirring frame 1414 stir the alloy liquid, making it more uniform, so that it can form an alloy with specific chemical and physical properties, thereby improving the alloy formation rate and shortening the alloy formation cycle.

[0044] Among them, the driving motor 6 and the rotating motor 15 rotate in opposite directions when rotating. When the driving motor 6 rotates three circles in the positive direction, the rotating motor 15 rotates three circles in the negative direction. When the driving motor 6 rotates three circles in the negative direction, the rotating motor 15 rotates three circles in the positive direction. Through this rotation method of the driving motor 6 and the rotating motor 15, the shortcomings of insufficient smelting and high impurity content of ordinary stirrers and smelting furnaces in the past are solved, so that the smelting impurities of the alloy are less, the composition is more uniform and not segregated, especially the oxygen, nitrogen and hydrogen content is reduced, avoiding the harm of oxygen, nitrogen and hydrogen to the metal, preventing the alloy from forming pores, generating cold cracks, causing oxidation and splashing, thereby enhancing its hot or cold workability, as well as ductility, toughness and fatigue strength performance.

[0045] The working principle and use process of the present invention:

[0046] First, the driving motor 6 drives the driving ring 8 to rotate, the driving ring 8 drives the driving shaft 9 to rotate, the driving shaft 9 drives the driving plate 13 to rotate, and the driving plate 13 drives the limiting plate 16 to rotate along the limiting ring groove 1601. The active component 17 meshes and rotates with the connecting gear 11 through the rotation of the driving plate 13;

[0047] When the driving assembly 17 is rotated by the driving plate 13, the driving plate 13 drives the driving shaft 1712 to move, and the driving shaft 1712 drives the first driving gear 1711 to move. Since the first driving gear 1711 is engaged with the connecting gear 11, the first driving gear 1711 drives the second driving gear 1713 to rotate through the driving shaft 1712.

[0048] During the rotation of the second driving gear 1713, the driven gear 18 is engaged with the second driving gear 1713, and the driven gear 18 drives the driven assembly 20 to rotate. At this time, the driven plate 2011 drives the driven rod 2012 to rotate with the driven shaft 19 as the center. The second stirring assembly 21 also rotates with the driven shaft 19 as the center through the driven assembly 20.

[0049] The second stirring shaft 2111 drives the second stirring blade 2112 to rotate via the driven rod 2012. At this time, the second abutment plate 2113 also abuts against the stirring drum 4 with the driven shaft 19 as the center and rotates. The second stirring blade 2112 stirs the alloy liquid during the continuous rotation. While the second stirring assembly 21 rotates, the first stirring assembly 14 rotates via the rotary motor 15.

[0050] The rotating motor 15 drives the first stirring shaft 1413 to rotate, the first abutment plate 1416 abuts against the original position of the stirring drum 4 and rotates, the first stirring blade 1415 rotates through the first stirring shaft 1413, and the first stirring shaft 1413 simultaneously drives the stirring frame 1414 to rotate. At this time, the stirring frame 1414 and the first stirring blade 1415 both stir the alloy liquid and complete the operation.

[0051] Take the argon-filled stirring device of the present invention for example to produce ER5356 aluminum alloy welding wire:

[0052] Amount of argon gas filled: per minute / 10L

[0053] Pressure value: 0.2MPa

[0057] ② Stir once in the upper, middle and lower layers of the furnace for 15 minutes each time;

[0059] ④After the slag is removed, keep it warm;

[0060] ⑤ Raise the temperature to 750°C, introduce argon again, and stir;

[0061] ⑥ Stir once in the upper, middle and lower layers of the furnace, each time for 15 minutes.
