Description

Technical Field

[0001] This invention relates to the technical field of slag removal from molten aluminum, and more specifically, to a slag removal device for molten aluminum ladle. Background Technology

[0002] An aluminum ladle is a high-temperature resistant container used for the temporary transfer of molten aluminum (metallic aluminum that is in a liquid state after melting). It is mainly used for the temporary storage, transfer, and pouring of molten aluminum. There are many structures, but two common ones are: the first is a cylindrical body with a drain pipe, similar in structure to a teapot; the second is a cylindrical body with duckbill-shaped discharge nozzles at the opening edge. These nozzles are usually arranged in pairs facing each other to allow for discharge to both sides.

[0003] Because the molten aluminum in the aluminum ladle is constantly at a high temperature, it undergoes an oxidation reaction in real time during the transfer process. It may react with various substances in the air to produce scum that floats on the surface, as well as impurities generated during the production process. As the molten aluminum settles, these scum gradually rise to the surface. If this scum is not removed when using the molten aluminum for casting or other operations, it can easily affect the quality of the product and cause adverse effects such as cavities inside the product.

[0004] For the first type of aluminum ladle, because its discharge pipe is more regular in shape (round tube) than the inlet pipe, it is easy to install a filtration device on the discharge pipe. However, for the second type of aluminum ladle, its discharge nozzle is more irregular in shape, making it difficult to install a suitable filtration device (mainly because the filtration device is difficult to fix). In this case, it is necessary to use a special filtration device, or to manually remove the scum in real time during the discharge process, but the high-temperature environment is not friendly to workers. Therefore, a filtration device that can be better adapted to the duckbill-shaped discharge nozzle of the aluminum ladle can be designed. Summary of the Invention

[0005] The purpose of this invention is to provide a slag removal device for aluminum molten ladle, which can be more stably fixed at the discharge nozzle of the aluminum molten ladle and is also very convenient to replace.

[0006] The embodiments of the present invention are achieved through the following technical solutions: The slag removal device for the aluminum ladle of the present invention includes a pair of oppositely arranged conical filter buckets, a connecting member for connecting the pair of filter buckets, an insert rod disposed on the edge of the opening side of the filter bucket, and a pair of limiting cylinders respectively disposed on the lower side of the discharge nozzle on the inner wall of the aluminum ladle; the outer wall of the filter bucket is in contact with the inner wall of the discharge nozzle, and the insert rod is inserted into the limiting cylinder.

[0007] Furthermore, the connector includes a sleeve disposed inside the filter bucket, and a connecting rod passing through a pair of sleeves simultaneously; the axis of the sleeve coincides with the axis of the filter bucket; the sleeve penetrates the filter bucket.

[0008] Furthermore, a fixing ring is provided on the edge of the filter bucket opening side, and the fixing ring is connected to the filter bucket through a pair of connecting pieces; a sliding cylinder is sleeved on the fixing ring, and the sliding cylinder is connected to the insertion rod.

[0009] Furthermore, both the sleeve and the connecting rod have square cross-sections.

[0010] Furthermore, the connector further includes a pair of first baffles disposed at the end of the sleeve away from the filter bucket; the pair of first baffles are respectively disposed on opposite sides of the sleeve and are both hinged to the sleeve, the ends of the pair of baffles away from the sleeve abut against each other and form an arched structure; a first torsion spring is provided between the first baffles and the end of the sleeve; a groove is provided at one end of the connecting rod; the shape of the groove is the same as the shape formed by the pair of first baffles.

[0011] Furthermore, the connecting rod has a clearance hole on the side wall of the end away from the slot, a slider is slidably disposed inside the connecting rod, the slider is threadedly connected to a screw, a second baffle is disposed on the outer wall of the slider, the second baffle is hinged to the slider, and a second torsion spring is disposed between the second baffle and the slider; the clearance hole is used for the second baffle to pass through; the end of the screw away from the slider passes through the end of the connecting rod away from the slot.

[0012] Furthermore, a knob is provided at one end of the screw located outside the connecting rod.

[0013] Furthermore, a lever is provided on the outer wall of the end of the connecting rod away from the slot.

[0014] The technical solution of this invention has at least the following advantages and beneficial effects: In the aluminum ladle slag removal device of this invention, the insert rod on the filter bucket is first inserted into the limiting cylinder of the aluminum ladle, and the outer wall of the filter bucket is made to fit against the inner wall of the discharge nozzle. Then, a pair of filter buckets are connected using a connector to keep their relative positions fixed. Through the cooperation of the limiting cylinder and the insert rod, and the function of the connector, the filter bucket can be quickly installed at the discharge nozzle, efficiently filtering the molten aluminum during pouring. Throughout the process, the filter bucket is well fixed at the discharge nozzle and will not fall off. Furthermore, one filter bucket can be used multiple times, and when it becomes clogged, it can be easily removed and replaced. This not only improves the filtration effect of the aluminum ladle on slag and increases the quality of the product, but also reduces the labor intensity of workers. Attached Figure Description

Detailed Implementation

[0025] Example

[0026] The following description, in conjunction with specific embodiments, further illustrates the points, as shown in the appendix. Figure 1 - Appendix Figure 9As shown, the slag removal device of the aluminum ladle 11 in this embodiment includes a pair of oppositely arranged conical filter buckets 21, a connector for connecting the pair of filter buckets 21, an insertion rod 27 provided on the edge of the opening side of the filter bucket 21, and a pair of limiting cylinders 13 respectively provided on the lower side of the discharge nozzle 12 on the inner wall of the aluminum ladle 11; the outer wall of the filter bucket 21 is in contact with the inner wall of the discharge nozzle 12, and the insertion rod 27 is inserted into the limiting cylinder 13. Specifically, in use, first insert the rod 27 on the filter bucket 21 into the limiting cylinder 13 of the aluminum ladle 11, ensuring the outer wall of the filter bucket 21 fits against the inner wall of the discharge nozzle 12. Then, use a connector to connect a pair of filter buckets 21, fixing their relative positions. Through the cooperation of the limiting cylinder 13 and the rod 27, along with the connector, the filter bucket 21 can be quickly installed at the discharge nozzle 12, efficiently filtering the molten aluminum during pouring. Throughout the process, the filter bucket 21 remains firmly fixed at the discharge nozzle 12, preventing it from falling off. Furthermore, a single filter bucket 21 can be used multiple times, and when clogged, it can be easily removed and replaced. This not only improves the filtration effect of the aluminum ladle 11 on scum, enhancing the quality of the product, but also reduces the labor intensity of workers. It should be noted that the positions of the limiting cylinder 13 and the rod 27 can be interchanged, with the rod 27 placed inside the aluminum ladle 11 and the limiting cylinder 13 placed on the filter bucket 21.

[0027] In this embodiment, the connecting component includes a sleeve 22 disposed inside the filter hopper 21, and a connecting rod 31 passing through a pair of sleeves 22; the axis of the sleeve 22 coincides with the axis of the filter hopper 21; the sleeve 22 penetrates the filter hopper 21. Specifically, by inserting the connecting rod 31 into the sleeves 22 of the pair of filter hoppers 21, the pair of filter hoppers 21 can maintain their relative positions.

[0028] In this embodiment, a fixing ring 24 is provided on the edge of the opening side of the filter bucket 21. The fixing ring 24 is connected to the filter bucket 21 through a pair of connecting pieces 25. A sliding cylinder 26 is sleeved on the fixing ring 24, and the sliding cylinder 26 is connected to the insertion rod 27. The cross-section of the sleeve 22 and the connecting rod 31 is square. Specifically, after keeping its axis horizontal, the filter bucket 21 can also rotate around its axis (i.e., the sleeve 22) (due to the restriction of the connecting pieces 25, it can only perform reciprocating rotation of less than 180 degrees). During the filtration process, by rotating the filter bucket 21, the unblocked holes on the filter bucket 21 can be filtered, thereby improving the filtration efficiency (the filter hole structure on the filter bucket 21 is omitted in the attached figure). After the square connecting rod 31 passes through the square sleeve 22, the sleeve 22 can be directly rotated by rotating the connecting rod 31.

[0029] In this embodiment, the connector further includes a pair of first baffles 23 located at the end of the sleeve 22 away from the filter hopper 21. The pair of first baffles 23 are respectively located on opposite sides of the sleeve 22 and are both hinged to the sleeve 22. The ends of the pair of baffles away from the sleeve 22 abut against each other and form an arched structure. A first torsion spring is provided between the first baffles 23 and the end of the sleeve 22. A groove 32 is provided at one end of the connecting rod 31. The shape of the groove 32 is the same as the shape formed by the pair of first baffles 23. A clearance hole 33 is provided on the side wall of the end of the connecting rod 31 away from the groove 32. A slider 34 is slidably provided inside the connecting rod 31. A screw 35 is threadedly connected to the slider 34. A second baffle 36 is provided on the outer wall of the slider 34. The second baffle 36 is hinged to the slider 34. A second torsion spring is provided between the second baffle 36 and the slider 34. The clearance hole 33 is used for the second baffle 36 to pass through. The end of the screw 35 away from the slider 34 passes through the end of the connecting rod 31 away from the groove 32. Specifically, due to the action of the first torsion spring, when the first stop plate 23 is not under force, it exhibits... Figure 6 In the state of being in the middle, the connecting rod 31 is inserted from one end of the tip of one of the filter buckets 21 into the sleeve 22, which can push open the pair of first baffles 23 (as shown in the attached). Figure 7-8 As shown in the attached diagram, at this point, the first baffle 23 cannot block the connecting rod 31. When the connecting rod 31 continues to be inserted, the slot 32 at its end contacts the first baffle 23 of the other filter bucket 21. The first baffle 23 then embeds itself into the slot 32 and prevents the connecting rod 31 from further penetrating (as shown in the attached diagram). Figure 6 As shown in the attached diagram, rotating the connecting rod 31 at this time can also drive the filter bucket 21 to rotate through the cooperation of the slot 32 and the first baffle 23. Before the screw 35 rotates, the second baffle 36 is pressed inside the connecting rod 31 (as shown in the attached diagram). Figure 7 As shown in the figure, by rotating the screw 35, the slider 34 can be driven to move along the length direction of the screw 35 (that is, the length direction of the connecting rod 31, which is a hollow structure here). When the slider 34 and the second stop plate 36 move to the position of the clearance hole 33, under the action of the second torsion spring, the second stop plate 36 is pushed into the clearance hole 33 by the second torsion spring (as shown in the figure). Figure 8 As shown, the second baffle 36 is on the first baffle 23. By continuing to turn the screw 35, the second baffle 36 pushes the first baffle 23 to move. This causes the pair of filter buckets 21 to move in opposite directions, allowing them to fit more tightly against the discharge nozzle 12. During movement and discharge, they will not wobble, and molten aluminum will not enter between the filter buckets 21 and the discharge nozzle 12. By turning the screw 35 in the opposite direction, the second baffle 36 can be re-engaged into the connecting rod 31, allowing the connecting rod 31 to be removed from the sleeve 22.

[0030] In this embodiment, a knob 37 is provided at one end of the screw 35 outside the connecting rod 31. Specifically, the knob 37 makes it easier to turn the screw 35.

[0031] In this embodiment, a lever 38 is provided on the outer wall of the end of the connecting rod 31 away from the slot 32. Specifically, the lever 38 is used to rotate the connecting rod 31 more effectively.

[0032] In summary, the slag removal device for the aluminum ladle 11 in this embodiment first inserts the rod 27 on the filter bucket 21 into the limiting cylinder 13 of the aluminum ladle 11, and makes the outer wall of the filter bucket 21 fit against the inner wall of the discharge nozzle 12. Then, a pair of filter buckets 21 are connected using a connector to keep their relative positions fixed. In this way, through the cooperation of the limiting cylinder 13 and the rod 27, as well as the function of the connector, the filter bucket 21 can be quickly installed at the discharge nozzle 12, and the aluminum liquid is filtered efficiently when it is poured. Throughout the process, the filter bucket 21 can be well fixed at the discharge nozzle 12 without falling off. Moreover, one filter bucket 21 can be used multiple times, and it can be easily removed and replaced when it is clogged. This not only improves the filtration effect of the aluminum ladle 11 on slag and improves the quality of the product, but also reduces the labor intensity of workers.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
