Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy melt purification, and more specifically, to an alloy melt purification device. Background Art

[0002] During the aluminum alloy smelting process, the gases, various inclusions and other metal impurities in the melt often cause defects such as bubbles, pores, looseness, cracks, white spots, etc. in the aluminum alloy ingots, which have a significant impact on the processing performance of the ingots and the strength, plasticity, corrosion resistance and appearance quality of the products. Melt purification technology is a process method based on physical and chemical principles and corresponding process measures to remove gases, inclusions and harmful elements in the aluminum alloy melt in order to obtain pure metal melt.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", "provided on" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0032] See also Figure 1-5 A molten alloy purification device comprises a ceiling plate 1, a transmission shaft 2 is movably mounted at the lower end of the ceiling plate 1, a ventilation pipe is embedded in the transmission shaft 2, the other end of the ventilation pipe is connected to an air pump device, a stirring component 4 is mounted at the lower end of the transmission shaft 2, and a stirring component 2 6 is disposed at the lower end of the stirring component 4;

[0033] The stirring assembly 4 includes two upper and lower connecting seats 41, wherein the upper connecting seat 41 is connected to the bottom end of the transmission shaft 2, and an air pipe interface 44 is provided at the upper end of the connecting seat 41, and the air pipe interface 44 corresponds to the ventilation duct inside the transmission shaft 2, and a plurality of evenly distributed stirring rods 42 are installed between the inner walls of the upper and lower connecting seats 41, the interior of the stirring rod 42 is hollow, and a plurality of evenly distributed through holes 43 are provided at the side end of the stirring rod 42.

[0034] During the use of this scheme, in order to obtain a more efficient purification efficiency for the alloy melt during refining, in this embodiment, the personnel first use the air pump equipment to use a high-purity inert gas of more than 99.996% as a carrier, and evenly spray the refining agent from the ventilation pipe inside the transmission shaft 2 to the stirring rod 42, and finally spray it into the aluminum liquid through the through hole 43. In the process of spraying the refining agent, the personnel can synchronously start the transmission shaft 2 to cause the stirring component 4 to rotate as a whole, so that the refining agent is sprayed into the aluminum liquid under uniform rotation. At the same time, the stirring rod 42 can also stir the aluminum liquid to promote the mixing efficiency between the refining agent, the inert gas and the aluminum liquid, and accelerate the purification efficiency of the aluminum liquid.

[0035] The refining agent at this time can fully react with the aluminum liquid to separate the inclusions. At the same time, the inert gas captures these inclusions, alkali metals and hydrogen in the floating process and brings them to the surface of the aluminum liquid, realizing the separation of slag and aluminum, achieving the effect of refining, degassing and deslagging. At the same time, after sufficient stirring by the stirring component 4, the alloy composition and temperature of the aluminum liquid are uniform.

[0036] Moreover, in the present embodiment, with the continuous rotation of the stirring component 1 4, the stirring component 2 6 is synchronously swung by centrifugal rotation, thereby extending a plurality of stirring brackets, further enhancing the mixing efficiency between the refining agent, the inert gas and the aluminum liquid, accelerating the purification efficiency of the aluminum liquid, and at the same time being able to absorb the iron impurities in the raw materials during the stirring and mixing process and attach them to the surface. With the completion of the purification work, the plurality of stirring brackets extended by the stirring component 2 6 are retracted to the inside again, and the iron impurities are collected for subsequent unified cleaning;

[0037] Compared with the prior art, the utility model can efficiently complete the mixing work between the refining agent, the inert gas and the aluminum liquid, so that the refining agent can fully react with the aluminum liquid to separate the inclusions, and the inert gas captures these inclusions and the alkali metal and hydrogen during the floating process and brings them to the surface of the aluminum liquid, so as to realize the separation of slag and aluminum, achieve the effect of refining, degassing and deslagging, and accelerate the purification efficiency of the aluminum liquid. At the same time, under the action of the stirring component 1 4 and the stirring component 2 6, the alloy composition and temperature of the aluminum liquid are uniform, and the iron impurities in the raw materials can be sucked out for collection, which greatly improves the quality of the aluminum alloy.

[0038] See also Figure 1-3 The stirring assembly 6 includes a connecting seat 61 fixedly connected to the bottom end of the lower connecting seat 41, and a plurality of symmetrically distributed reset members 62 are installed on the bottom wall of the connecting seat 61. A stirring blade 63 is movably installed at the lower end of the reset member 62, and an iron collecting member 64 is installed at the bottom end of the connecting seat 61.

[0039] During use of the present solution, the stirring blades 63 are passively extended to the outside of the connecting seat 2 61 under the centrifugal rotation of the stirring component 1 4 , and the reset member 62 is deformed synchronously under the force. Under the rotation of the stirring component 1 4 , the extended stirring blades 63 can further enhance the mixing efficiency between the refining agent, inert gas and aluminum liquid, thereby accelerating the purification efficiency of the aluminum liquid.

[0040] See also Figure 1-4 The lower end of the stirring blade 63 is fixedly connected with a strong magnet 65.

[0041] During use of the present solution, as the multiple stirring blades 63 are extended and stirred, the strong magnets 65 rotate accordingly and adsorb and collect iron impurities in the aluminum liquid raw material, thereby improving the quality of the subsequent aluminum alloy.

[0042] See also Figure 1-4 The reset member 62 includes a top cover 621 fixedly connected to the bottom wall of the second connecting seat 61, a limiting hole 1 622 is provided on one side of the top cover 621, a base 623 is movably connected to the lower end of the top cover 621, a limiting hole 2 624 is provided at the bottom end of the base 623, a torsion spring 625 is sleeved at the center end of the base 623, wherein one side of the torsion spring 625 is engaged with the limiting hole 1 622, and the other side of the torsion spring 625 is engaged with the limiting hole 2 624, the stirring blade 63 is located at the lower side of the limiting hole 2 624, and a bolt 626 is installed through the lower side of the limiting hole 2 624.

[0043] During use of the present solution, the stirring blade 63 is connected to the base 623 by the bolt 626. When the stirring blade 63 is subjected to centrifugal rotation, the stirring blade 63, the strong magnet 65 and the base 623 rotate synchronously. Since one end of the torsion spring 625 is connected to the bottom of the base 623 and the other end is connected to the top cover 621, when the base 623 rotates, the torsion spring 625 is twisted and deformed by force.

[0044] Until the stirring assembly 4 is no longer in centrifugal rotation, the stirring blade 63 is gradually driven by the torsion spring 625 under the reset characteristic of being free from force, so as to drive the stirring blade 63 and the base 623 to rotate to the initial position.

[0045] See also Figure 1-5 The iron collecting member 64 includes a collecting plate 641 provided on the lower side of the connecting seat 61, a collecting groove 642 is opened at the upper end of the collecting plate 641, a stud 643 is installed at the center end of the collecting groove 642, a scraper 645 is fixedly connected to the upper end of the collecting plate 641, and the scraper 645 is located on one side of the collecting groove 642, a screw sleeve 644 is installed at the center position of the bottom end of the collecting plate 641, and the screw sleeve 644 and the stud 643 are threadedly connected.

[0046] During use of the present solution, as the stirring blade 63 and the strong magnet 65 gradually rotate in the initial direction under the action of the torsion spring 625, the bottom of the strong magnet 65 absorbs more iron impurities in the raw materials. Since the height of the strong magnet 65 is higher than the top of the collecting plate 641, until the strong magnet 65 rotates to the top of the collecting tank 642, the iron impurities absorbed by the bottom of the strong magnet 65 can be scraped off and collected in the collecting tank 642 due to the obstruction of the scraper 645. Subsequent personnel only need to rotate the entire collecting plate 641 to cause the stud 643 to disengage from the screw sleeve 644 to complete the separation of the two, so that the iron impurities collected in the collecting tank 642 can be cleaned up uniformly.

[0047] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
