Description

Technical Field

[0001] The utility model relates to the technical field of smelting equipment, in particular to a smelting device with aluminum liquid impurity filtering function. Background Art

[0002] In the existing aluminum processing industry, the melting furnace is a key equipment for preparing molten aluminum. Its performance and efficiency directly affect the quality and cost of the final product. Traditional melting furnace designs often rely on a motor-driven stirring shaft to achieve uniform mixing and temperature control of the molten aluminum.

[0003] During the stirring process, the traditional stirring shaft comes into direct contact with the high-temperature molten aluminum, causing the molten aluminum to adhere to the stirring shaft and be continuously consumed as it rotates. This not only reduces the utilization rate of the molten aluminum, increases production costs, and affects the purity and quality of the molten aluminum. During the aluminum processing process, raw aluminum blocks or recycled molten aluminum often contain various impurities. If these impurities are not effectively removed, they will affect the quality of products in subsequent processes. Therefore, in the existing smelting process, an additional filtration step is often required after smelting, which not only increases the complexity of the production process, but also reduces overall production efficiency. Utility Model Content

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention is further described in detail below with reference to the accompanying drawings.

[0027] A smelting device with aluminum liquid impurity filtration, such as Figure 1-Figure 5 As shown, it includes an integration box, a smelting furnace 1, a smelting furnace 1 feeding pipe and an outlet support box 3. The outlet support box 3 is installed in the integration box, and several smelting furnaces 1 are installed in an array on the integration box. An electromagnetic stirring device is installed in the smelting furnace 1, and a filtering adjustment device 2 is installed on the smelting furnace 1 feeding pipe. The outlet end of the smelting furnace 1 is located in the outlet support box 3. A filter plate 4 is detachably installed in the outlet support box 3. The filter plate 4 is located below the outlet end of the smelting furnace 1. Filter plate cleaning and collecting devices 5 are installed on both sides of the outlet support box 3. The outlet support box 3 is connected to the discharge pipeline 7. The number of smelting furnaces 1 is preferably two. One integration box is equipped with two smelting furnaces 1 to improve production efficiency. The two smelting furnaces 1 are arranged in an array and are both inclined. The body passes through one side of the integration box and extends into the outlet support box 3. The stirring shaft is removed by the electromagnetic stirring device, and the molten aluminum in the smelting furnace is stirred by electromagnetic force to reduce the loss of molten aluminum. The filtering and regulating device 2 on the feeding pipe of the smelting furnace 1 can be flexibly adjusted according to the feed type (aluminum block or molten aluminum) to ensure smooth and unobstructed feeding. When molten aluminum is used as feeding material, it is preliminarily filtered and purified through the filtering and regulating device 2. After smelting is completed, secondary filtration is performed to effectively improve the final purity of the molten aluminum. The filtering devices all use high-temperature resistant ceramic filter plates 4. By installing two smelting furnaces 1 in an array at an angle in the integration box, not only the space utilization is optimized, but also the parallel operation of the two furnaces is realized, which effectively improves the smelting speed and processing capacity of the entire production line.

[0028] The feeding pipe of the smelting furnace 1 passes through the top surface of the integration box, and the filtering and adjusting device 2 is installed on the top surface of the integration box. The filtering and adjusting device 2 includes a screw assembly 21 and a sliding filter plate 22. The sliding filter plate 22 is movably installed on the screw assembly 21. The screw assembly 21 passes through the feeding pipe of the smelting furnace 1. The sliding filter plate 22 is slidably connected with the feeding pipe of the smelting furnace 1 through the screw assembly 21. The feeding pipe of the smelting furnace 1 extends out from the highest point of the integration box and passes through the top surface of the integration box. A through groove is provided on it that is adapted to the sliding filter plate 22, and the transmission screw and slide rod of the screw assembly 21 pass through the through groove. The sliding filter plate 22 is adapted to be clamped with the through groove to prevent the flow of molten aluminum when feeding. The sliding filter plate 22 can be adjusted by adjusting the position of the sliding filter plate 22 through the screw assembly 21 to alternate between the two areas, and the other area can also be cleaned and maintained. The sliding filter plate 22 includes an aluminum block straight-through area and an aluminum liquid filtration area. Both the aluminum block straight-through area and the aluminum liquid filtration area are compatible with the feed pipe of the smelting furnace 1. The aluminum liquid filtration area can be easily maintained and the filter plate replaced by adjusting the position. The position of the sliding filter plate 22 is precisely controlled by the screw assembly 21, achieving rapid switching between the aluminum block straight-through area and the aluminum liquid filtration area, which not only simplifies the operating process but also effectively improves production efficiency and flexibility. The aluminum liquid filtration area performs preliminary filtration on the incoming aluminum liquid. At the same time, by regularly replacing or maintaining the filter plate 4, the continuity and stability of the filtration effect can be maintained.

[0029] A placement table 8 and a concave support table 9 are provided in the integration box. The outlet support box 3 is located between the placement table 8 and the concave support table 9. The concave support table 9 is screwed between the outer side of the outlet support box 3 and the inner wall of the integration box, and is located above the discharge pipe 7. The filter plate cleaning and collecting device 5 includes a cleaning block 51, a pushing cylinder 52, a blocking block 53 and a cylinder 54. The cleaning block 51 and the blocking block 53 are relatively arranged. The cleaning block 51 is connected to the telescopic end of the pushing cylinder 52, and the blocking block 53 is connected to the cylinder 54. The telescopic ends of the cylinder 54 are connected, and the top surface of the filter plate 4 abuts the cleaning block 51. A cleaning push is provided on the side of the cleaning block 51 away from the pushing cylinder 52. The cleaning push is close to the filter plate 4 and is in a right-angled triangle shape, pushing the residual impurities on the filter plate 4 into the waste collection box 6, avoiding the residue of impurities on the filter plate 4, thereby ensuring the smoothness of the subsequent aluminum liquid filtration. When the smelted aluminum liquid is completely discharged, the cylinder 54 drives the blocking block 53 to unblock and store it, and the material-returning cylinder pushes the cleaning block 5 1. The filtered impurities are cleaned. The cleaning block 51 and the blocking block 53 are both adapted to the slots of the outlet support box 3. The pushing electric cylinder 52 is installed on the placing table 8, and the cylinder 54 is installed on the concave support platform 9. A waste collection box 6 is installed on the concave support platform 9. The waste collection box 6 is located between the cylinder 54 and the outlet support box 3. The discharge is filtered through the filter plate 4 to purify the molten aluminum, effectively improving the final quality. The cleaning block 51 and the blocking block 53 are adapted to the slots on the outlet support box 3 to prevent the molten aluminum from leaking, which not only ensures the smooth flow of molten aluminum, but also provides a stable installation foundation for the filter plate cleaning and collecting device 5. The height of the waste collection box 6 is consistent with the height of the through slot, which is convenient for storing impurities and waste. The cleaning block 51 and the blocking block 53 are at the same horizontal height. One end of the filter plate 4 close to the blocking block 53 is clamped on the inner wall of the outlet support box 3, and the other end is screwed to the outer wall of the outlet support box 3. The cleaning block 51 and the blocking block 53 also play a sealing role.

[0030] A material guide slope is provided in the outlet support box 3, and the discharge pipeline 7 is opened on the outlet support box 3 on the other side of the material guide slope. The material guide slope is located below the filter plate 4. The material guide slope guides the molten aluminum to the discharge pipeline 7. The inner wall of the outlet support box 3 at the lowest point of the material guide pipeline is provided with a material guide groove inclined toward the discharge pipeline 7, which effectively guides the filtered molten aluminum to flow along a preset path, reduces turbulence and splashing of the molten aluminum during the flow process, and ensures that the molten aluminum can enter the discharge pipeline 7 smoothly and orderly. The material guide slope is in the shape of a large slope arc, which effectively avoids the retention and backflow of the molten aluminum in the discharge area after the filtration is completed, thereby improving the overall production and discharge efficiency.

[0031] The smelting furnace 1 and other parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.

[0032] Working principle: The staff loads the smelting furnace 1 through the feeding pipe. According to the raw material (aluminum block or molten aluminum), the sliding filter plate 22 is adjusted to be in the aluminum block straight-through area or the aluminum molten aluminum filtration area. The raw aluminum block directly passes through the smelting furnace 1, while the raw aluminum molten aluminum undergoes the first preliminary filtration. The smelting furnace 1 stirs the aluminum molten aluminum in the smelting furnace through the electromagnetic stirring device. After smelting is completed, the outlet of the smelting furnace 1 automatically opens to discharge the material.

[0033] At this time, the smelted aluminum liquid is finally filtered and purified through the filter plate 4. After the aluminum liquid is poured out and enters the cooling period, the cylinder 54 is started first to drive the blocking block 53 to shrink, so that the blocking block 53 is separated from the outlet support box 3. The pushing electric cylinder 52 is further started to push the cleaning block 51. The residual impurities on the filter plate 4 are cleaned by the cleaning cylinder 52 and pushed into the waste collection box 6. Subsequently, the cleaning block 51 and the blocking block 53 are reset to complete the sealing by the pushing electric cylinder 52 and the cylinder 54 respectively.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
