Description

Technical Field

[0001] This utility model relates to the field of smelting equipment, and more specifically, to an aluminum melting furnace. Background Technology

[0002] Aluminum melting furnaces are key equipment in the aluminum processing industry, mainly used for melting, holding, and adjusting the composition of aluminum and aluminum alloys. Traditional aluminum melting furnaces typically use gas, oil, or resistance heating methods, which result in high energy consumption, low thermal efficiency, and significant environmental pollution.

[0003] In the prior art, such as the simplified aluminum melting furnace with publication number CN203413951U, the furnace includes a furnace body, a fixed column connected to the furnace body, a support rod with one end fitted to the upper end of the fixed column for rotation, and the other end fixed to a connecting plate. A cover is welded to the lower end of the connecting plate, and a handle is welded to the support rod. This furnace uses a cover to conceal the furnace opening, preventing heat loss. However, frequently opening and closing the cover when removing molten aluminum is inconvenient. Furthermore, when the cover is opened, the molten aluminum inside the furnace comes into contact with the outside air. Due to the lower outside air temperature, the temperature of the molten aluminum at the top of the furnace decreases, easily forming a hard aluminum film, which affects the removal process. Utility Model Content

[0004] Therefore, in order to solve the problem that contact between molten aluminum and external air will affect the aluminum extraction process, this utility model provides an aluminum melting furnace, the specific technical solution of which is as follows:

[0005] An aluminum melting furnace includes a melting mechanism and a heat preservation structure. The melting mechanism includes a shifting frame and a furnace body rotatably mounted on the shifting frame. The furnace body is provided with a melting chamber and a liquid outlet tank communicating with the opening of the melting chamber. A heating device is arranged around the outer periphery of the melting chamber. A monitoring device communicating with the interior of the melting chamber is inserted into the furnace body. The heat preservation structure includes a heat preservation tank cover and a cover plate covering the opening of the melting chamber. The heat preservation tank cover is connected to the cover plate and covers the top of the liquid outlet tank. A heat preservation layer is provided at the bottom of the heat preservation tank cover. A liquid outlet channel for molten aluminum to flow is formed between the heat preservation layer and the liquid outlet tank.

[0006] The aforementioned aluminum melting furnace is equipped with a liquid outlet channel to guide the molten aluminum out of the furnace, ensuring that the molten aluminum flows out along a preset path. This protects the melting chamber and the external environment from the effects of molten aluminum overflow or backflow. The monitoring device allows operators to constantly monitor the temperature inside and outside the melting chamber, ensuring the temperature remains within a safe range and avoiding safety risks caused by excessively high or low temperatures. The insulation tank cover prevents the molten aluminum from contacting the outside air as it flows through the outlet channel and is discharged. Its insulation effect also helps to lower the temperature of the molten aluminum to some extent, preventing the formation of a hard aluminum film and avoiding any impact on the aluminum removal process.

[0007] Furthermore, the shifting frame includes a frame body, two bearing seats and multiple moving wheels. A pusher is connected to the frame body, the two bearing seats are symmetrically arranged on both sides of the top of the frame body, and the multiple moving wheels are respectively and spaced apart and assembled at the bottom of the frame body.

[0009] Furthermore, a melting chamber is provided inside the furnace body, the bottom of the melting chamber is inserted into the melting chamber, and the heating device is connected and fixed on the inner wall of the melting chamber and surrounds the outer wall of the bottom of the melting chamber.

[0010] Furthermore, the heating device includes multiple heating components arranged vertically in sequence. Each heating component includes a heating ring and two mounting plates. The heating ring has an inner ring opening, which is fitted onto the outer periphery of the bottom outer wall of the melting chamber. The two sides of the heating ring are integrally formed with the mounting plates, and the mounting plates have multiple mounting holes.

[0011] Furthermore, the heating ring includes a first heating part at the center and second heating parts symmetrically arranged on both sides. The second heating part is formed by connecting multiple heating strips end to end. The outermost end of the heating strip is integrally formed with the mounting plate, and the innermost end of the heating strip is integrally formed with the first heating part.

[0012] Furthermore, the monitoring device includes an external monitoring component and an internal monitoring component. The external monitoring component includes an external temperature measurement module and an external probe, and the internal monitoring component includes an internal temperature measurement module and an internal probe. Both the external and internal temperature measurement modules are mounted on the cover plate. One end of the external probe is connected to the external temperature measurement module, and the other end of the external probe extends to the space between the melting chamber and the melting cavity body. One end of the internal probe is connected to the internal temperature measurement module, and the other end of the internal probe extends into the interior of the melting cavity body.

[0013] Furthermore, the insulation structure also includes a feeding cover disposed on the top of the cover plate, the cover plate having a communication port communicating with the interior of the melting chamber, the feeding cover covering the communication port, and a handle connected to the top of the feeding cover.

[0025] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0026] like Figures 1-3As shown, an aluminum melting furnace according to one embodiment of the present invention includes a melting mechanism and a heat preservation structure. The melting mechanism includes a shifting frame 1 and a furnace body 2 rotatably mounted on the shifting frame 1. The furnace body 2 is provided with a melting chamber 21 and a liquid outlet tank 22 communicating with the opening of the melting chamber 21. A heating device 3 is arranged around the outer periphery of the melting chamber 21. A monitoring device 4 communicating with the interior of the melting chamber 21 is inserted into the furnace body 2. The heat preservation structure includes a heat preservation tank cover 5 and a cover plate 6 covering the opening of the melting chamber 21. The heat preservation tank cover 5 is connected to the cover plate 6 and covers the top of the liquid outlet tank 22. A heat preservation layer is provided at the bottom of the heat preservation tank cover 5. A liquid outlet channel for aluminum to flow is formed between the heat preservation layer and the liquid outlet tank 22.

[0027] The aforementioned aluminum melting furnace, by being equipped with a liquid outlet trough 22, guides the molten aluminum out of the furnace, ensuring that the molten aluminum flows out along a preset path, thereby protecting the melting chamber 21 and the external environment from the effects of molten aluminum overflow or backflow. The monitoring device 4 allows operators to constantly monitor the temperature inside and outside the melting chamber 21, ensuring the temperature remains within a safe range and avoiding safety risks caused by excessively high or low temperatures. The insulation tank cover 5 ensures that the molten aluminum does not come into contact with external air as it flows through the liquid outlet channel and is discharged. Its insulation effect also helps to lower the temperature of the molten aluminum to some extent, preventing the formation of a hard aluminum film and avoiding any impact on the aluminum removal process.

[0028] like Figure 1 As shown, in one embodiment, the shifting frame 1 includes a frame body 11, two bearing seats 12, and multiple casters 13. A pusher 14 is connected to the frame body 11. The two bearing seats 12 are symmetrically arranged on both sides of the top of the frame body 11, and the multiple casters 13 are spaced apart and mounted on the bottom of the frame body 11. This facilitates the relocation of the furnace body 2 and is beneficial for adapting to adjustments and maintenance of the production line.

[0029] like Figure 1 As shown, in one embodiment, a rotating shaft is provided on the bearing seat 12, and two connecting seats 23 are symmetrically arranged on the outer wall of the furnace body 2. One end of the rotating shaft is rotatably assembled in the bearing seat 12, and the other end of the rotating shaft is fixedly inserted into the connecting seat 23. The rotation of the rotating shaft drives the furnace body 2 to reciprocate on the frame 11, thereby facilitating the discharge of molten aluminum from the outlet channel.

[0030] In one embodiment, a melting chamber is provided inside the furnace body 2, the bottom of the melting chamber 21 is inserted into the melting chamber, and the heating device 3 is connected and fixed on the inner wall of the melting chamber and surrounds the outer wall of the bottom of the melting chamber 21.

[0031] like Figure 3 and Figure 4As shown, in one embodiment, the heating device 3 includes multiple heating components arranged vertically. Each heating component includes a heating ring 31 and two mounting plates 32. The heating ring 31 has an inner ring opening that fits around the outer periphery of the bottom outer wall of the melting chamber 21. Both sides of the heating ring 31 are integrally formed with the mounting plates 32, and the mounting plates 32 have multiple mounting holes 321. The mounting holes 321 enable the heating ring 31 to be detachably installed.

[0032] Specifically, the heating ring 31 adopts a series and parallel design, thereby increasing the total length and cross-sectional area of ​​the heating ring 31 circuit and ultimately ensuring that the total resistance of the heating ring 31 meets the usage requirements.

[0033] like Figure 4 As shown, in one embodiment, the heating ring 31 includes a first heating part 311 at the center and a second heating part 312 symmetrically arranged on both sides. The second heating part 312 is formed by connecting multiple heating strips end to end. The outermost heating strip is integrally formed with the mounting plate 32, and the innermost heating strip is integrally formed with the first heating part 311.

[0034] Specifically, the first heating part 311 is annular; the second heating part 312 is formed by connecting two or more arc-shaped heating strips end to end.

[0035] like Figure 4 As shown, the heating assembly further includes an electrode plate 33, which has a slot for mounting a mounting plate 32 and a corresponding through hole. The mounting plate 32 is inserted into the slot of the electrode plate 33, and the through hole in the slot is aligned with the corresponding mounting hole 321 on the mounting plate 32. The plate is then fixedly connected by a carbon graphite bolt 322.

[0036] Furthermore, the end of the electrode plate 33 furthest from the slot is provided with a graphite bolt hole 331 for fixing the electrode. This allows for adjustable installation of the electrode plate 33 at different distances.

[0037] The heating principle of the heating device 3 described above is existing technology, and its specific principle and technical features will not be described in more detail here.

[0038] like Figures 1-3As shown, in one embodiment, the monitoring device 4 includes an external monitoring component 41 and an internal monitoring component 42. The external monitoring component 41 includes an external temperature measurement module and an external probe, while the internal monitoring component 42 includes an internal temperature measurement module 421 and an internal probe 422. Both the external and internal temperature measurement modules 421 are mounted on the cover plate 6. One end of the external probe is connected to the external temperature measurement module, and the other end extends between the melting chamber and the melting cavity 21. One end of the internal probe 422 is connected to the internal temperature measurement module 421, and the other end extends into the interior of the melting cavity 21. This device can monitor the temperature changes inside and outside the melting cavity 21 in real time. If any abnormal or inconsistent temperature changes are detected, the operator can immediately take measures to prevent accidents.

[0039] Preferably, both the external temperature measurement module and the internal temperature measurement module 421 are thermocouples. The application of thermocouples in temperature measurement is existing technology, and their working principle and installation connection method will not be described in detail here.

[0040] like Figure 1 As shown, in one embodiment, the insulation structure also includes a feeding cover 7 disposed on the top of the cover plate 6. The cover plate 6 has a communication port that communicates with the interior of the melting chamber 21. The feeding cover 7 is placed on the communication port, and a handle 71 is connected to the top of the feeding cover 7.

[0041] In one embodiment, a dust-collecting layer is provided on the top of the heat-insulating tank cover 5, and a heat-insulating board is provided on top of the dust-collecting layer. The dust-collecting layer, the heat-insulating board, and the outer side of the heat-insulating layer are all covered with a layer of heat-insulating blanket. This further enhances the heat-insulating effect of the heat-insulating tank cover 5.

[0042] Preferably, the thermal insulation blanket is made of fire-resistant cotton.

[0043] In one embodiment, one end of the liquid outlet 22 is connected to the opening of the melting chamber 21, and the other end of the liquid outlet 22 is provided with a liquid outlet that protrudes and extends to the outside of the furnace body 2.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
