Description

Refined agitator of aluminum alloy

Technical Field

The utility model relates to an aluminium alloy concise field of making especially relates to an aluminium alloy concise agitator.

Background

In the process of smelting and casting aluminum and aluminum alloy, because a large amount of bubbles and impurities exist in purchased aluminum ingots, dissolved hydrogen atoms in a melt are easy to form bubbles after being separated out during casting and solidification, and defects are generated in aluminum and aluminum alloy ingots or castings. Therefore, in the production of aluminum and aluminum alloys, it is necessary to reduce the hydrogen content and remove inclusions by refining treatment. In the prior art, after an aluminum ingot is melted by heating, a refining agent is generally scattered on the surface of aluminum liquid, and then an iron bar is used for stirring to remove gas and impurities. However, such an operation can remove only the molten aluminum having a crucible depth of 1/3, and the refining effect is not good. And the aluminum ingot is put in a crucible for melting, the size of the crucible of 300kg is phi 500x600, and the temperature of the molten aluminum is 680-720 ℃. The operation of sprinkling the refining agent and stirring cannot be made too close to the deep due to the high temperature, causing the drawback of local stirring operation.

And the handle works, so that the worker can be far away from the heat source, and the influence of high-temperature aluminum liquid is avoided.

The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments thereof, taken in conjunction with the accompanying drawings.

Drawings

Some specific embodiments of the present invention will be described in detail hereinafter, by way of illustration and not by way of limitation, with reference to the accompanying drawings. The same reference numbers in the drawings identify the same or similar elements or components. Those skilled in the art will appreciate that the drawings are not necessarily drawn to scale. In the drawings:

FIG. 1 is a three-view illustration of an aluminum alloy refining stirrer according to one embodiment of the present invention, wherein the front view is a full sectional view of the stirrer.

The symbols in the drawings have the following meanings:

1-a storage bucket; 2-stirring blade; 3-anti-falling stop block; 4-a handle; 5-through hole.

Detailed Description

As shown in fig. 1, the aluminum alloy refining stirrer mainly comprises: a storage barrel 1, a handle 4 and a stirring blade 2. The refining agent is white powder or granular flux, is prepared by mixing a plurality of inorganic salts according to a certain proportion after drying treatment, and is mainly used for removing hydrogen and floating oxidation slag inclusion in molten aluminum. The utility model discloses press into phi 80x60 size refining agent piece with the refining agent to put into storage bucket 1 with the refining agent. The size of the refining agent pieces may also be other suitable sizes. Then, the material storage barrel 1 enters the crucible with the opening facing downwards and the bottom facing upwards and sinks to the bottom of the aluminum liquid.

In the present embodiment, at least three stirring vanes 2 are fixed to the periphery of the opening of the storage bucket 1, and the blades of the stirring vanes 2 are parallel to the axis of the storage bucket 1. When the storage barrel 1 rotates around the axis thereof, the stirring blades 2 rotate along with the rotation, and the blades are stirred in the molten aluminum.

The handle 4 is arranged at the bottom of the storage bucket 1. Wherein the handle 4 comprises a first rod and a second rod. The first rod is perpendicular to the bottom surface of the storage barrel 1, one end of the first rod is arranged at the bottom of the storage barrel 1, and the other end of the first rod is connected to the second rod. One end of the second rod is connected with the first rod, and the other end of the second rod extends outwards to be far away from the storage barrel 1. The length of the first rod is more than or equal to 1.5 m. Also, the angle between the second rod and the first rod is 90 ° or more, and in the present embodiment, the angle between the second rod and the first rod is a right angle. Consequently, the second pole of the handheld handle of staff and stirring can keep away from the heat source center, drive first pole and rotate, drive storage bucket 1 then and stir leaf 2 and rotate.

The opening of the storage barrel 1 is provided with a detachable anti-falling stop block 3. The projected area of anticreep dog 3 at 1 opening part of storage bucket is less than the open area of storage bucket 1, that is to say, anticreep dog 3 does not seal storage bucket 1's opening, but plays the effect of avoiding storage bucket 1 opening when down, and the refining agent piece breaks away from storage bucket 1.

The body of the storage bucket 1 has a plurality of through holes 5. The plurality of through holes 5 are distributed in the barrel body in an array of rows and columns. The through holes 5 can enhance the communication between the inside and the outside of the barrel. In this embodiment, the diameter of the single through-hole 5 is Φ 10. The through hole array is four rows which are evenly distributed.

Utilize above-mentioned aluminium alloy refining agitator, the staff can put into storage bucket 1 with the refining agent piece, and handheld handle 4 keeps away from the heat source, avoids being influenced by high temperature. The staff utilizes handle 4 directly to sink storage bucket 1 to the crucible bottom to thereby rotate handle 4 and drive storage bucket 1 rotatory. When the high-temperature aluminum liquid meets the refining agent, chemical reaction can immediately occur, and the aluminum liquid can be seen to boil and roll from bottom to top. The phenomenon is mainly caused by the fact that air II exists in the aluminum liquid, after the aluminum liquid is waited for 2-3 minutes, the surface of the aluminum liquid is stable, the deslagging agent is sprinkled, impurities can be seen to be gathered on the surface of the aluminum liquid, and then manual slag scraping is carried out, so that the refining process is completed. The utility model discloses a degassing, slagging-off are reliable comprehensive, begin to clear away from the crucible bottom, easy operation, and the cost of manufacture is low. And manual stirring is performed, so that the effect of the stirring blades is fully exerted, the working range is expanded, and the optimal stirring effect is achieved.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
