DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] Embodiment one

[0027] To solve the technical problems in the background art, the following aluminum alloy product smelting equipment is given:

[0028] In combination Figures 1-4 As shown in the figure, the aluminum alloy product smelting equipment provided by the present application comprises a furnace shell 1, which is hollow inside, and a material opening 11 is formed in the top of the furnace shell 1 and communicates with the inside of the furnace shell 1. A support seat 2 is fixedly installed at the bottom inside the furnace shell 1, and a crucible 21 is arranged on the top of the support seat 2. The top of the crucible 21 is attached to the inner bottom wall of the furnace shell 1, and the material opening 11 communicates with the inside of the crucible 21. An annular refractory brick 22 is fixedly arranged inside the furnace shell 1 and outside the crucible 21. The top of the annular refractory brick 22 is fixedly connected to the top of the outer sidewall of the crucible 21. A combustion chamber 12 is formed between the annular refractory brick 22 and the crucible 21, and a ventilation chamber 13 is formed between the annular refractory brick 22 and the inner sidewall of the furnace shell 1. A notch 221 is formed in the top of the annular refractory brick 22, so that the combustion chamber 12 and the ventilation chamber 13 communicate with each other through the notch 221.

[0029] An exhaust pipe 4 is fixedly installed on one side of the furnace shell 1 and communicates with its interior. The top of the exhaust pipe 4 extends above the furnace shell 1. A horizontal vent pipe 41 is connected through the side of the exhaust pipe 4 near the furnace shell 1. A filter element 5 for filtering air is installed inside the vent pipe 41. A connecting pipe 42 that can communicate with the vent pipe 41 is hinged to one side of the vent pipe 41. A positioning element 6 connected to the connecting pipe 42 is installed on the vent pipe 41 and is used to fix or unfix the connection between the connecting pipe 42 and the vent pipe 41. An exhaust pipe 43 is connected through the bottom of the connecting pipe 42 and the bottom end of the exhaust pipe 43 is inclined towards the material inlet 11.

[0030] In use, when smelting aluminum alloy raw materials, the raw materials are fed into the crucible 21 through the feed port 11. Ignition is then performed inside the combustion chamber 12 to heat and burn the crucible 21, thereby melting the aluminum alloy raw materials inside. During the smelting process, the generated waste gas enters the ventilation chamber 13 through the notch 221, and is then discharged through the exhaust pipe 4, ventilation pipe 41, connecting pipe 42, and outlet pipe 43. The heated waste gas, when discharged through the outlet pipe 43, blows towards the crucible 21, thus drawing more heated waste gas into the crucible 21. This design achieves further heating of the aluminum alloy raw material inside the crucible 21, effectively preventing the waste of thermal energy caused by the direct discharge of waste gas into the ambient air, which is conducive to the development needs of energy conservation. Furthermore, when the waste gas carrying heat flows inside the ventilation chamber 13, it increases the air temperature inside the ventilation chamber 13, thereby achieving a heat preservation effect on the outside of the annular refractory brick 22. Through the design of the filter element 5, the air flowing through the ventilation pipe 41 into the connecting pipe 42 is filtered, effectively preventing the smoke and dust in the waste gas from being blown into the crucible 21 and affecting the quality of the aluminum alloy melt.

[0031] Example 2

[0032] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following:

[0033] In this embodiment, the filter element 5 is a filter plate 51, which is a high-efficiency filter. The end of the vent pipe 41 is provided with a slot 411. The filter plate 51 is inserted into the slot 411 and the inside of the vent pipe 41 is sealed. When in use, when the gas flows from the exhaust pipe 4 to the outlet pipe 43 and comes into contact with the filter plate 51, the air can be filtered by the filter plate 51. By setting the filter plate 51 to be inserted into the slot 411, it is convenient to install and remove the filter plate 51. In this embodiment, the connecting pipe 42 and the vent pipe 41 are fixed by the positioning element 6. When the connecting pipe 42 and the vent pipe 41 are connected, the connecting pipe 42 limits the position of the filter plate 51.

[0034] In this embodiment, the positioning component 6 includes a positioning frame 61, a positioning frame 62, a rotating column 63, and a positioning pin 64. A positioning frame 61 with a U-shaped longitudinal section is fixedly installed on one side of the vent pipe 41. A positioning frame 62 with a U-shaped longitudinal section is fixedly installed on the side of the connecting pipe 42 near the positioning frame 62. A vertically oriented rotating column 63 is rotatably installed between the concave surfaces of the positioning frame 62. A positioning pin 64 is threaded horizontally through the rotating column 63. The positioning pin 64 can be inserted between the concave surfaces of the positioning frame 61 and abuts against the side of the positioning frame 61 away from the positioning frame 62. In use, the connecting pipe 42 is rotated on the vent pipe 41, connecting the connecting pipe 42 to the vent pipe 41, so that the positioning frame 62 and the positioning frame 61 are located on the vent pipe. On the same side of 41, the rotating column 63 rotates inside the second positioning frame 62, causing the positioning pin 64 to rotate around the rotating column 63. This allows the positioning pin 64 to be inserted into the inside of the first positioning frame 61. Then, rotating the positioning pin 64 causes it to move spirally on the rotating column 63, causing the positioning pin 64 to abut against the side of the first positioning frame 61 away from the second positioning frame 62. This achieves the positioning effect between the second positioning frame 62 and the first positioning frame 61, thus achieving the positioning effect between the connecting pipe 42 and the vent pipe 41. Conversely, rotating the positioning pin 64 in the opposite direction so that it does not abut against the first positioning frame 61 causes the rotating column 63 to rotate, causing the positioning pin 64 to rotate to the outside of the first positioning frame 61. This cancels the positioning between the second positioning frame 62 and the first positioning frame 61, making the operation simple.

[0035] In this embodiment, a base 7 is also included. A horizontal rotating shaft 71 is symmetrically fixed on the side of the furnace shell 1 away from the exhaust pipe 4. A fixing frame 72 is symmetrically fixed on the top side of the base 7. The furnace shell 1 is rotatably mounted on the top of the two fixing frames 72 via the two rotating shafts 71, and there is a gap between the furnace shell 1 and the base 7. A hydraulic cylinder 73 is hinged to the top of the base 7 and on the side of the fixing frame 72. The other ends of the two hydraulic cylinders 73 are both hinged to the furnace shell 1. By setting up the base 7, rotating shafts 71 and hydraulic cylinders 73, when the aluminum alloy material in the crucible 21 is melted and the aluminum alloy liquid is discharged, the two hydraulic cylinders 73 are controlled to make the furnace shell 1 rotate around the two rotating shafts 71, so that the crucible 21 tilts downward along the direction of the open end, and the aluminum alloy solution in the crucible 21 can be poured out and discharged, which facilitates the discharge of the aluminum alloy solution in the crucible 21.

[0036] Example 3

[0037] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following:

[0038] In the embodiment, the gap 221 is located on the side of the crucible 21 away from the exhaust pipe 4, a liquid discharge groove 211 is arranged on the top of the crucible 21 and close to the gap 221, a mounting hole 14 is arranged on the top of the furnace shell 1 and away from the exhaust pipe 4, a guide block 8 is fixedly arranged on the furnace shell 1 and in the mounting hole 14, and the end of the guide block 8 close to the crucible 21 is downwardly inclined and penetrates through the gap 221 and is in close contact with the outer side wall of the crucible 21, and a liquid guide groove 81 is arranged on the top of the guide block 8. By arranging the liquid discharge groove 211 and the guide block 8, when the aluminum alloy melt is discharged, the furnace shell 1 is rotated around the two rotating shafts 71 by controlling the two hydraulic cylinders 73, so that the crucible 21 is inclined downward along the opening end direction, and during the process, the aluminum alloy solution can be discharged through the liquid discharge groove 211 and the liquid guide groove 81, effectively avoiding the aluminum alloy melt flowing on the top of the furnace shell 1, thereby avoiding the slag hanging on the top of the furnace shell 1.

[0039] In the embodiment, the furnace shell 1 is provided with a maintenance opening 15 on the bottom of the side away from the exhaust pipe 4, the bottom of the annular refractory brick 22 is provided with a through hole 222, a communication shell 16 is fixedly arranged on the furnace shell 1 and in the maintenance opening 15, one end of the communication shell 16 extends into the through hole 222, the outer side wall of the communication shell 16 is in close contact with the inner side wall of the through hole 222, which is convenient for observing and maintaining the inside of the combustion chamber 12, the communication shell 16 is hingedly connected with a sealing plate 17 for sealing the end of the communication shell 16, the sealing plate 17 is provided with a second positioning member 18 connected with the communication shell 16, which is used for fixing or unfixing the sealing plate 17 and the communication shell 16.
