Description

Technical Field

[0001] The utility model relates to the field of aluminum product production and processing, in particular to an aluminum chip side well placing device. Background Art

[0002] Existing aluminum product production lines typically consist of a heating furnace and a smelting furnace. The heating furnace heats and melts aluminum lump into hot molten aluminum (containing impurities), which is then fed into a conveyor channel. This hot molten aluminum is then transported to the smelting furnace for smelting, where impurities are removed, resulting in a relatively pure aluminum liquid for use in subsequent production processes. This subsequent production process generates a large amount of aluminum chips, which are collected and recycled and fed back into the heating furnace to be melted again into molten aluminum. Most of this aluminum chips are in powdery form (or debris). When fed into the heating furnace, these chips are easily blown away and scattered. Because the heating furnace is sealed when heating the aluminum material into hot molten aluminum, to prevent dust explosions caused by this seal, production personnel must wait until the raised powdery aluminum chips have completely fallen before starting the heating furnace. To this end, the hot aluminum liquid can be left in the heating furnace without being removed. The recovered aluminum chips can then be added to the furnace, where the hot aluminum liquid in the furnace uses its own residual heat to melt the aluminum chips. At this point, since the aluminum material has already been melted into hot liquid aluminum, the heating furnace does not need to be sealed and heated, making dust explosions less likely. However, since some aluminum chips are clumped together due to impurities such as organic oil and moisture adhering to their surfaces, the residual heat of the hot aluminum liquid alone cannot completely melt them, affecting the quality of the aluminum liquid. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an aluminum chip side well feeding device, which is not likely to cause dust explosion and affect the quality of aluminum liquid during the process of feeding aluminum chips.

[0004] In order to solve the above problems, the utility model provides an aluminum chip side well delivery device, which includes a heating furnace and a smelting furnace. The heating furnace and the smelting furnace are connected by a conveying channel. The aluminum material in the heating furnace is heated and melted into aluminum liquid, and the aluminum liquid is transported to the smelting furnace through the conveying channel for smelting. A delivery well is provided in the conveying channel. The delivery well receives aluminum chips to be recycled and delivers these aluminum chips into the aluminum liquid transported to the smelting furnace along the conveying channel; a stirring mechanism for stirring the aluminum chips is provided in the delivery well.

[0005] Furthermore, the delivery well is vertically arranged above the conveying channel, and an upper portion thereof is provided with a feed port for receiving the aluminum chips to be recycled and a lower portion thereof is provided with a discharge port connected to the conveying channel.

[0006] Furthermore, the stirring mechanism is specifically a stirring screw installed vertically in the delivery well, and the stirring screw rotates around its own vertical axis to stir the aluminum chips.

[0007] Furthermore, a radially extending stirring blade is provided at the lower end of the stirring screw, which extends into the conveying channel through the discharge port of the delivery well to stir the aluminum liquid transported to the smelting furnace along the conveying channel.

[0008] Furthermore, the upper portion of the delivery well is funnel-shaped.

[0009] Furthermore, a conveying device is provided to convey the aluminum chips to be recycled to the feeding port of the delivery well.

[0010] Beneficial effects: The aluminum chip side well delivery device of the present invention delivers the aluminum chips to be recycled into the high-temperature aluminum liquid in the conveying channel, allowing the high-temperature aluminum liquid to melt the aluminum chips with its own waste heat. Unlike the background technology, the aluminum chips are not delivered into the heating furnace, and the heating furnace can be sealed as usual to heat the aluminum material inside and melt it into high-temperature aluminum liquid, which is not easy to cause dust explosion. In the process of being delivered into the conveying channel, the aluminum chips are first stirred by the stirring mechanism provided in the delivery well, and the aluminum chips that are stuck together into larger blocks are thus dispersed by the stirring mechanism. Therefore, the aluminum chips delivered into the high-temperature aluminum liquid in the conveying channel are smaller in volume and are easily melted by the high-temperature aluminum liquid, so they are not easy to affect the quality of the aluminum liquid.

[0014] The present invention is further described in detail below in conjunction with specific embodiments.

[0015] Aluminum chips side well delivery device see Figure 1 , comprising a heating furnace 1 on the left and a smelting furnace 2 on the right, connected by a conveying channel 3. The heating furnace 1 heats and melts aluminum lump into high-temperature molten aluminum 4 (containing impurities), which is then delivered to the conveying channel 3. This high-temperature molten aluminum 4 is transported via the conveying channel 3 to the smelting furnace 2 for smelting, where impurities are removed, resulting in relatively pure aluminum liquid for use in subsequent production processes. In actual production, the heating furnace 1 continuously heats and melts multiple batches of aluminum lump into high-temperature molten aluminum 4, which are then delivered to the conveying channel 3, allowing the high-temperature molten aluminum 4 to continuously flow along the conveying channel 3 to the smelting furnace 2 for smelting. The heating furnace 1, smelting furnace 2, and conveying channel 3 are prior art, and their specific structures and operating principles are not described in detail here.

[0016] A hollow, vertical drop-in well 6 is located above the conveying channel 3. The drop-in well 6 is connected vertically, with a funnel-shaped upper portion serving as an inlet 61 and a lower portion providing an outlet 62 connected to the conveying channel 3. A conveyor belt 7 is located above the inlet 61, serving as a conveyor. During subsequent production processes, aluminum chips 5 are generated. These chips are recovered and transported by the conveyor belt 7 to the inlet 61 of the drop-in well 6. From the inlet 61, these chips enter the drop-in well 6 and enter the conveying channel 3 through the outlet 62. There, they are then dropped into the high-temperature molten aluminum 4 being transported along the conveying channel 3 to the smelting furnace 2. The chips are then melted by the residual heat of the high-temperature molten aluminum 4. The melted aluminum chips 5 are then transported along with the high-temperature molten aluminum 4 to the smelting furnace 2 for smelting. Since the aluminum chips 5 are introduced into the high-temperature aluminum liquid 4 in the conveying channel 3 through the introduction well 6, the high-temperature aluminum liquid 4 melts the aluminum chips 5 by its own residual heat, and the conveying channel 3 itself is not completely sealed (e.g., connected to the outside world through the introduction well 6), the conveying channel 3 will not cause a dust explosion during the melting process of the aluminum chips 5. In addition, unlike the background art, the aluminum chips 5 are not introduced into the heating furnace 1 in this embodiment, so the heating furnace 1 can be sealed as usual, and the aluminum material inside it is heated and melted into the high-temperature aluminum liquid 4 without causing a dust explosion. In addition, the burning loss of the aluminum chips 5 is reduced (the existing method of introducing the aluminum chips 5 into the heating furnace 1 for heating causes relatively serious burning loss), thereby improving the recycling rate of the aluminum chips 5.

[0017] A small portion of the aluminum chips 5, due to impurities such as organic oil and water adhering to their surfaces, forms large clumps. This makes it difficult to completely melt the aluminum chips 5 with the residual heat of the hot molten aluminum 4 alone, thus affecting the quality of the molten aluminum. To this end, a mounting member 63 is installed inside the delivery well 6, near the discharge port 62. A portion of the mounting member 63 is left partially open to form a clearance space 64 for the aluminum chips 5 to pass through. A vertical stirring screw 8 is mounted at the center of the mounting member 63. The stirring screw 8 extends downward and is equipped with a rotating motor (not shown). Driven by the rotating motor, the stirring screw 8 rotates around its vertical axis to stir the aluminum chips 5 passing through it, breaking up any large clumps. This reduces the volume of the aluminum chips 5 released into the hot molten aluminum 4, making them easier to melt and less likely to affect the quality of the molten aluminum. Furthermore, since the aluminum chips 5 contain water, once this water accumulates in large clumps due to the aluminum chips 5 clumping together, it is prone to explosion when heated and volatilized. By stirring the aluminum chips 5 as described above, the stirring screw 8 prevents this water from gathering and thus preventing explosions. A radially extending stirring blade 81 is provided at the lower end of the stirring screw 8, which extends into the high-temperature aluminum liquid 4 in the conveying channel 3 through the discharge port 62 of the feeding well 6. In this way, when the aluminum chips 5 are fed into the high-temperature aluminum liquid 4, the stirring screw 8 rotates around its own vertical axis, driving the stirring blade 81 to disperse the high-temperature aluminum liquid 4 passing directly below the feeding well 6 and the aluminum chips 5 that have been fed into the high-temperature aluminum liquid 4, making it less likely for the aluminum chips 5 to stick together and more easily melted by the high-temperature aluminum liquid 4.

[0018] In this embodiment, the stirring screw 8 serves as a stirring mechanism, which can drive and stir the aluminum chips 5 passing through, thereby breaking up the aluminum chips 5 that are clumped together into larger pieces. In other embodiments, the stirring mechanism may not be the stirring screw 8, but may instead be a plurality of sets of stirring blades (the structure of which can refer to the stirring blades 81 of this embodiment) spaced from top to bottom in the delivery well 6. The plurality of stirring blades rotate about a vertical axis to break up the aluminum chips 5 that are clumped together into larger pieces.

[0019] The above is only an embodiment of the present invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the present invention and still fall within the scope of patent protection.
