Description

Technical Field

[0001] This utility model relates to the field of aluminum material processing technology, specifically a dual-furnace aluminum material melting device. Background Technology

[0002] The aluminum melting furnace is a new type of high-efficiency and energy-saving furnace developed based on the aluminum smelting process.

[0003] Chinese Patent CN115979016A discloses a novel dual-chamber aluminum melting furnace platform, comprising an aluminum melting furnace with a partition fixed at the center of the furnace interior. A melting chamber, a preheating chamber, and a drive chamber are arranged on both sides of the partition. The furnace also includes: a stirring mechanism installed in both the melting chamber and the drive chamber; and a feeding mechanism installed in the preheating chamber. One end of the feeding mechanism is connected to the melting chamber via an exhaust pipe, and the other end is connected to a discharge pipe. This feeding mechanism can intermittently deliver molten aluminum material into the melting chamber, preventing accumulation. Furthermore, the feeding mechanism, in conjunction with the exhaust and discharge pipes, can preheat the molten aluminum material using the gas emitted from the melting chamber, improving melting efficiency, shortening melting time, and enabling energy reuse.

[0004] In the above technical solution, the indirect feeding effect is achieved by rotating the feeding seat. When the aluminum material is large, after entering the feeding chamber, the aluminum material inside the feeding chamber shakes as the feeding seat rotates, which can easily cause it to get stuck in the feeding chamber, thus affecting the conveying of the aluminum material. Furthermore, the feeding seat is located inside the mounting base, which is a whole unit and is not convenient to disassemble or maintain the internal feeding seat, thus reducing the practicality of the device.

[0005] Based on this, this application proposes a dual-furnace aluminum melting device. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a dual-furnace aluminum melting device, which can crush aluminum material through a crushing roller, thereby increasing the heating area of ​​the aluminum material and accelerating its melting. The combination of a fixed shell and a movable shell makes the feeding tray of the device easy to disassemble and maintain, thus improving the practicality of the device.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a dual-furnace aluminum melting device, including a furnace body, a feeding pipe fixedly connected to the furnace body, two discharge ports opened on the feeding pipe, two fixed shells fixedly connected to the furnace body, four feeding ports opened on the two fixed shells, the feeding ports and the discharge ports being connected, and further including;

[0008] The furnace body has two movable shells that are movably connected to two fixed shells. The two fixed shells are fixedly connected to a plurality of connecting lugs. The two movable shells are fixed to the two fixed shells by a plurality of bolts and a plurality of connecting lugs. A rotating door is rotatably connected to the furnace body.

[0009] Preferably, a motor is fixedly connected to the feed pipe, and two crushing rollers are rotatably connected inside the feed pipe. A crushing roller is fixedly connected to the output shaft of the motor, and two gears are fixedly connected to each of the two crushing rollers, and the two gears mesh with each other.

[0010] Preferably, four feeding discs are rotatably connected inside the two fixed shells and the two movable shells, and each of the four feeding discs has multiple feeding slots and multiple preheating chambers, with multiple baffles fixedly connected inside each of the multiple preheating chambers.

[0011] Preferably, two motors are fixedly connected to the furnace body, and two rotating shafts are fixedly connected to the output shafts of the two motors respectively, and the four feeding discs are slidably connected to the two rotating shafts respectively.

[0012] Preferably, a partition is fixedly connected inside the furnace body, and two feeding ports are opened on the partition. Two motors are fixedly connected to the furnace body, and two stirring rods are fixedly connected to the output shafts of the two motors respectively. Two aluminum melting chambers are opened inside the furnace body.

[0013] Preferably, the partition has two exhaust holes, and two connecting pipes are fixedly connected to the two exhaust holes respectively. The two connecting pipes are fixedly connected to the two fixed shells respectively. Two connecting pipes are fixedly connected to the two fixed shells respectively. A discharge pipe is fixedly connected to the two connecting pipes and the discharge pipe is fixedly connected to the furnace body.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] Firstly, in this utility model, a motor drives one of the crushing rollers to rotate, and one of the gears rotates accordingly. Since the two gears mesh with each other, the other crushing roller starts to rotate, crushing the aluminum material, increasing the heating area of ​​the aluminum material, thereby accelerating the melting of the aluminum material and improving the working efficiency of the device.

[0016] Secondly, in this utility model, by removing the bolts on the connecting ears, the fixed shell and the movable shell can be separated, and the feeding tray on them can also be separated, so that the feeding groove in the feeding tray can be cleaned and dredged, making the device easy to maintain and improving its practicality.

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0026] This utility model provides an improved dual-furnace aluminum melting device. The technical solution of this utility model is as follows:

[0027] like Figures 1-5 As shown, a dual-furnace aluminum melting device includes a furnace body 1, a feed pipe 2 fixedly connected to the furnace body 1, two discharge ports 6 opened on the feed pipe 2, the two discharge ports 6 being symmetrical about the discharge pipe 25, two fixed shells 7 fixedly connected inside the furnace body 1, four feed ports 8 opened on the two fixed shells 7, the two feed ports 8 being symmetrical about the rotating shaft 14, the feed ports 8 being connected to the discharge ports 6, and also includes;

[0028] The movable shell 16 is movably connected to two fixed shells 7. Multiple connecting ears 15 are fixedly connected to the two fixed shells 7. The two movable shells 16 are fixed to the two fixed shells 7 by multiple bolts and multiple connecting ears 15. A rotating door 17 is rotatably connected to the furnace body 1. By removing the bolts on the connecting ears 15, the fixed shells 7 and the movable shells 16 can be separated, and the feeding tray 9 on them can also be separated. The feeding trough 10 in the feeding tray 9 can then be cleaned and unblocked, making the device easy to maintain and improving its practicality.

[0029] Furthermore, such as Figures 1-4 As shown, a motor 3 is fixed to the feed pipe 2 by bolts. Two crushing rollers 4 are rotatably connected inside the feed pipe 2. The output shaft of the motor 3 is fixed to the crushing rollers 4 by a coupling. Two gears 5 are fixedly connected to the two crushing rollers 4 respectively. The two gears 5 mesh with each other. The motor 3 drives one of the crushing rollers 4 to rotate, and one of the gears 5 rotates accordingly. Since the two gears 5 mesh with each other, the other crushing roller 4 starts to rotate, crushing the aluminum material, increasing the heating area of ​​the aluminum material, thereby accelerating the melting of the aluminum material and improving the working efficiency of the device.

[0030] Furthermore, such as Figure 4 and Figure 5 As shown, four feeding discs 9 are rotatably connected inside the two fixed shells 7 and the two movable shells 16 respectively. Multiple feeding grooves 10 and multiple preheating chambers 11 are respectively opened on the four feeding discs 9. The feeding grooves 10 are arranged in a ring array with the center of the feeding discs 9 as the center. Multiple baffles 12 are fixedly connected inside the multiple preheating chambers 11 respectively.

[0031] Furthermore, such as Figures 3-5 As shown, two motors 13 are fixed to the furnace body 1 by bolts. Two rotating shafts 14 are fixed to the output shafts of the two motors 13 by couplings. Four feeding discs 9 are slidably connected to the two rotating shafts 14. The feeding discs 9 rotate with the rotating shafts 14, which drives the feeding trough 10 to rotate, so that the feeding trough 10 periodically meets the feed inlet 8, thereby completing intermittent feeding.

[0032] Furthermore, such as Figures 1-4 As shown, a partition 18 is fixedly connected inside the furnace body 1. Two feeding ports 6 are opened on the partition 18. The cross section of the partition 18 is "T" shaped. Two motors 19 are fixed to the furnace body 1 by bolts. Two stirring rods 20 are connected to the output shafts of the two motors 19 by couplings. Two aluminum melting chambers 21 are opened inside the furnace body 1.

[0033] Furthermore, such as Figures 2-4As shown, two exhaust holes 22 are opened on the partition plate 18, and two connecting pipes 23 are fixedly connected to the two exhaust holes 22 respectively. The two connecting pipes 23 are fixedly connected to the two fixed shells 7 respectively. Two connecting pipes 24 are fixedly connected to the two fixed shells 7 respectively. When the preheating chamber 11 periodically encounters the connecting pipes 23 and 24, the hot air in the aluminum melting chamber 21 enters the preheating chamber 11 to preheat the aluminum material in the feeding trough 10. The two connecting pipes 24 are fixedly connected to the discharge pipes 25, which are fixedly connected to the furnace body 1.

[0034] The specific working method is as follows: Aluminum material is placed into the feed pipe 2. Motor 1 (3) is started, and its output shaft drives one of the crushing rollers 4 to rotate. One of the gears 5 rotates accordingly. Because the two gears 5 mesh, the other crushing roller 4 begins to rotate, crushing the aluminum material and increasing its heating area, thereby accelerating its melting. The crushed aluminum material falls into the discharge port 6, enters the feed port 8, and then enters the feeding trough 10. Motor 2 (13) is started, and its output shaft drives the rotating shaft 14 to rotate. Because the feeding disc 9 is slidably connected to the rotating shaft 14, the feeding disc 9 rotates with the rotating shaft 14, causing the aluminum material in the feeding trough 10 to rotate. When the feeding disc 9 rotates, the aluminum material in the feeding trough 10 rotates. When the material trough 10 rotates to the bottom of the fixed shell 7, the material trough 10 overlaps with the inlet 8 at the bottom of the fixed shell 7. The aluminum material inside will enter the aluminum melting chamber 21 through the inlet 8. Start the motor 3 19, and its output shaft drives the stirring rod 20 to rotate, stirring the aluminum material in the aluminum melting chamber 21 and accelerating the melting of the aluminum material. When it is necessary to maintain and clean the feeding tray 9, turn to open the rotating door 17, turn the bolts on the connecting ear 15, and remove all the bolts on the connecting ear 15. At this time, the moving shell 16 is no longer fixed and can be removed. Since the feeding tray 9 is rotatably connected to the moving shell 16, the feeding tray 9 is also removed, and the feeding trough 10 in the feeding tray 9 can be cleaned and unclogged.

[0035] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
