Description

Technical Field

[0001] This utility model relates to the field of metal casting technology, and more specifically, to a slag removal mechanism for an aluminum furnace. Background Technology

[0002] Before aluminum ingots are formed, solid aluminum blocks need to be melted into molten aluminum, and then the molten aluminum is poured into a mold to form aluminum ingots. During the process of melting aluminum blocks into molten aluminum, impurities will float on the surface of the molten aluminum, and workers need to remove the impurities.

[0003] The existing publicly available technology application number is CN202321511293.0, which discloses an aluminum slag removal device. It uses a control rod to push and pull a rotating rod, which drives the rotating rod to rotate laterally and change the direction of the scraping plate. It can remove the floating slag on both sides of the inside of the melting furnace, especially the floating slag on the side corners near the edge of the melting furnace. It effectively reduces the swing amplitude of the main rod, saves the labor of workers, and ensures that the floating slag on the surface of the aluminum liquid is fully removed.

[0004] However, the aforementioned patent still has certain drawbacks in its use: it can only collect scum, and personnel still need to use scum-removing tools to remove the scum afterward, which is not very practical. Furthermore, the range of scum removal and scum retrieval that it can apply is relatively limited. The rotating rod needs to be rotated to expand the working range, which is time-consuming and laborious. The working range is also relatively limited. Moreover, when removing scum near the inner area, workers need to stretch their arms, and the scorching temperature makes it unbearable for workers, which is dangerous. Overall, the effect of its use is not ideal.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a slag removal mechanism for aluminum furnaces, which has the advantages of wide slag removal range, labor-saving operation, and high operational safety, thereby solving the problems mentioned in the background technology.

[0008] (II) Technical Solution

[0009] To achieve the advantages of wide slag removal range, labor-saving operation, and high operational safety, the specific technical solution adopted by this utility model is as follows:

[0010] A slag removal mechanism for an aluminum furnace includes a sealing cover and a handle. A motor is installed at the top center of the sealing cover. One end of the motor passes through one side of the sealing cover and is connected to a drive shaft. A drive arm is installed at the bottom of one side surface of the drive shaft. A support arm is welded to the other side of the drive shaft at the bottom of the sealing cover. A collection box is installed at the bottom of the support arm. Guide plates are symmetrically and obliquely installed on both sides of the top of the collection box and on both sides of the inner top.

[0011] Furthermore, an adjustment groove is provided inside the drive arm, an anti-detachment plate is slidably connected inside the adjustment groove, a moving strip is welded to the bottom of the anti-detachment plate, a scraper is installed at the bottom of the moving strip, and several sets of springs are installed between the anti-detachment plate and the inner wall of the adjustment groove.

[0012] Furthermore, a sealing groove is provided on the bottom surface of the sealing cover.

[0013] Furthermore, a handle is welded to one side of the top of the sealing cap.

[0014] Furthermore, several sets of leakage holes are provided on the surface of the collection box and the surface of the guide plate.

[0015] Furthermore, the scraper is made of metal.

[0016] Furthermore, the sealing cover is larger than the size of the aluminum furnace.

[0017] Furthermore, the dimensions of the sealing groove are the same as the dimensions of the top of the aluminum furnace.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a slag removal mechanism for aluminum furnaces, which has the following beneficial effects:

[0020] (1) This utility model adopts a drive arm and a collection box. When slag is being removed, the rotation of the drive arm can drive the scraper to rotate along the inside of the aluminum furnace, thereby expanding the overall working area. Moreover, when rotating, the scraper at the bottom can push the slag floating on the surface of the molten aluminum, and then push the slag into the collection box through the guide plate to achieve the collection operation. Since the drive arm can be driven to rotate by a motor, it can significantly reduce the labor intensity of personnel compared with manual operation. At the same time, the rotatable structure also increases the working range, making it easier to remove slag from different positions, expanding the applicability of the device, improving the use effect, and having the advantages of wide slag removal range and labor-saving operation.

[0021] (2) This utility model adopts a sealing cover and a handle. During operation, the personnel can move the sealing cover by the handle, without the personnel having direct contact with the aluminum furnace. Therefore, it can reduce the probability of personnel being burned by high temperature. At the same time, the sealing cover can cover and seal the top of the aluminum furnace to prevent the aluminum liquid from splashing out and splattering on the personnel when slag is removed. The slag removal operation is also achieved by the motor, without the need for manual operation, avoiding contact between personnel and the aluminum liquid or even the aluminum furnace. The use of multiple sets of structures can effectively improve the safety of the device and has the advantage of high operational safety. Attached Figure Description

[0029] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0030] According to an embodiment of the present invention, a slag removal mechanism for an aluminum furnace is provided.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, an aluminum furnace slag removal mechanism according to an embodiment of the present utility model includes a sealing cover 1 and a handle 15. A motor 2 is installed at the top center of the sealing cover 1. One end of the motor 2 passes through one side of the sealing cover 1 and is connected to a drive shaft 3. A drive arm 13 is installed at the bottom of one side of the drive shaft 3. A support arm 5 is welded to the other side of the drive shaft 3 at the bottom of the sealing cover 1. A collection box 6 is installed at the bottom of the support arm 5. Guide plates 7 are symmetrically and obliquely installed on both sides of the top of the collection box 6 and on both sides of the inner top.

[0032] In one embodiment, an adjustment groove 11 is provided inside the drive arm 13, and an anti-detachment plate 12 is slidably connected inside the adjustment groove 11. A moving strip 10 is welded to the bottom of the anti-detachment plate 12, and a scraper 9 is installed at the bottom of the moving strip 10. Several sets of springs 14 are installed between the anti-detachment plate 12 and the inner wall of the adjustment groove 11. The springs 14 are designed to change the length of the scraper 9 and the moving strip 10 through deformation and compression, thereby ensuring that the scraper 9 can move along the guide plate 7 and push the scum into the collection box 6 for collection.

[0033] In one embodiment, a sealing groove 4 is provided on the bottom surface of the sealing cover 1.

[0034] In one embodiment, a handle 15 is welded to one side of the top of the sealing cover 1. The handle 15 is provided to facilitate the movement of the sealing cover 1 by personnel.

[0035] In one embodiment, several sets of leakage holes 8 are provided on the surface of the collection box 6 and the surface of the guide plate 7. The leakage holes 8 are provided to discharge excess aluminum liquid and effectively collect slag for subsequent processing.

[0036] In one embodiment, the scraper 9 is made of metal. The metal material is used to ensure that the scraper 9 can be used smoothly in high-temperature environments, avoiding damage to the scraper 9 caused by traditional plastic, rubber and other materials, which would affect the slag removal operation.

[0037] In one embodiment, the size of the sealing cover 1 is larger than that of the aluminum furnace. The size of the sealing cover 1 is larger than that of the aluminum furnace to ensure that it can smoothly cover and seal the top of the aluminum furnace and prevent the internal molten aluminum from leaking out. At the same time, the size of the middle position of the sealing cover 1, that is, the area on the other side of the sealing groove 4, is the same as that of the aluminum furnace, so that the structure installed on it can smoothly perform a sufficient slag removal operation on the internal slag.

[0038] In one embodiment, the sealing groove 4 is the same size as the top of the aluminum furnace. The sealing groove 4 is designed to be locked at the top of the aluminum furnace to achieve a sealing operation. The top size of the aluminum furnace referred to here is the thickness of the ring formed by the top of the aluminum furnace when viewed from above.

[0039] Working Principle: In actual use, the operator can move the device using handle 15. Then, the sealing cover 1 is placed on top of the aluminum furnace to be processed. The sealing groove 4 on the surface of the sealing cover 1 can then engage with the surface of the aluminum furnace, thus sealing the top of the furnace. Next, the support arm 5 at the bottom of the sealing cover 1, along with the collection box 6, is inserted into the molten aluminum inside the furnace, with the collection box 6 above the surface of the molten aluminum. The guide plates 7 on both sides can be inserted into or level with the molten aluminum. The motor 2 drives the drive shaft 3 to rotate, which in turn drives the connected drive arm 13 to rotate. The rotation of the drive arm 13 allows it to cover any position inside the aluminum furnace. When the drive arm 13 and its surface scraper 9 are idle, the scraper 9 at the bottom can be inserted into or level with the molten aluminum. Thus, the drive arm 13 drives the scraper 9... During rotation, the scraper 9 contacts the molten aluminum, scraping away the scum floating on the surface. As the drive arm 13 rotates, the scraper 9 contacts the guide plate 7, pushing the scum along the guide plate 7 into the collection box 6. Since a spring 14 is located below the moving bar 10 at the bottom of the scraper 9, the compression of the spring 14 allows the scraper 9 to perform a corresponding compression operation as it moves along the guide plate 7, ensuring that the scraper 9 can smoothly push the scum into the collection box 6. Because the collection box 6 is higher than the surface of the molten aluminum, the scum pushed into it can be effectively collected and will not be discharged again. After the operation is completed, the entire structure can be raised by lifting the handle 15. At this time, the molten aluminum inside the collection box 6 can be discharged through the drain hole 8, while the scum remains inside the collection box 6 for easy subsequent processing. The device has the advantages of wide scum removal range, labor-saving operation, and high operational safety.
