With the widespread application of aluminum profiles in aviation, automobiles, construction, machinery and other industries, the requirements for aluminum quality and processing efficiency are becoming higher and higher. Therefore, more efficient, energy-saving and environmentally friendly aluminum profile furnaces are needed to meet market demand.

[0003] A Chinese patent discloses a furnace for industrial aluminum profiles (authorization announcement number CN208366066U). The patented technology is rationally designed and very suitable for industrial aluminum profile furnaces. By providing a centrifuge and a filter device in a coordinated operation mode, the molten aluminum is discharged through the centrifuge and the aluminum slag is filtered and collected through the filter device.

The bottom of the knob 11 abuts against the top of the cross plate 7. By turning the knob 11, the rotating rod 10 is driven to rotate inside the base 9 until the knob 11 no longer restricts the cross plate 7. Then, the cross plate 7 is rotated to drive the fixing rod 8 away from the furnace cover 3, making it convenient for the user to open the furnace cover 3. After the furnace cover 3 is closed, the furnace cover 3 is reinforced by the above structure, which can significantly improve its structural stability and enable it to withstand greater pressure and impact. The wear resistance, erosion resistance and thermal shock resistance of the furnace cover 3 are enhanced, thereby extending the service life of the furnace cover 3, reducing the downtime and maintenance time caused by damage to the furnace cover 3, and improving the utilization rate and production efficiency of the furnace body 1.

[0025] Reference Figure 3As shown, in this embodiment: a through groove 12 is provided on the surface of the horizontal plate 7, the interior of the through groove 12 is slidingly connected to a limit block 13, and the interior of the limit block 13 is slidingly connected to the rotating rod 10. By setting the structure of the through groove 12 and the limit block 13, the vertical direction of the rotating rod 10 can be restricted to avoid tilting. At the same time, the threaded connection between the rotating rod 10 and the base 9 will not change without the action of external force.

[0026] Reference Figure 2 As shown, in this embodiment: a receiving seat 14 is fixed to the top of the furnace body 1, and an annular block 16 is fixed to the bottom of the furnace cover 3. An annular groove 15 is provided on the top of the receiving seat 14 for plugging and cooperating with the annular block 16. By setting the structure of the receiving seat 14, the annular groove 15 and the annular block 16, when the furnace cover 3 is closed, a seal is formed between the annular block 16 and the annular groove 15, which reduces heat loss and leakage of gas in the furnace body 1, helps to maintain the temperature stability in the furnace body 1, improves smelting efficiency, and reduces energy consumption. At the same time, good sealing performance can also reduce the pollution of the gas in the furnace body 1 and improve the working environment.

[0027] Reference Figure 4 As shown, in this embodiment: an inner cavity 17 is opened inside the furnace body 1. By providing the inner cavity 17, a vacuum zone can be formed between the smelting chamber and the furnace body 1, further improving energy consumption and avoiding heat loss.

[0028] Reference Figure 4-Figure 6 As shown, in this embodiment: an exhaust pipe 18 is fixed through one side of the furnace body 1, and a shell 19 is fixed on the surface of the exhaust pipe 18. An exhaust pump 20 is installed on the surface of the exhaust pipe 18 on the right side of the shell 19. A baffle 21 is slidably connected to the inside of the shell 19, and a connecting rod 22 is fixed on the top of the baffle 21. A cross bar 23 is fixed on the top of the connecting rod 22. Both ends of the cross bar 23 are slidably connected to a sleeve 24. Fixed plates 25 are fixed on both sides of the top of the shell 19. The surface of the fixing plate 25 is provided with a plurality of limiting holes 26 for plugging and cooperating with the sleeve 24. By setting the exhaust pipe 18 and connecting it to the inner cavity 17, the sleeve 24 is pulled toward the cross bar 23 to move the sleeve 24 out of the limiting hole 26, and the cross bar 23 can be pulled to drive the connecting rod 22 to pull the baffle 21 upward, and the exhaust pump 20 is used to extract the gas inside the inner cavity 17 to form a vacuum, thereby avoiding heat loss and improving heat utilization efficiency.

[0029] Reference Figure 6As shown, in this embodiment: a spring 27 is fixed inside the sleeve 24, and the other end of the spring 27 is fixed to the cross bar 23. By setting the spring 27, when the sleeve 24 is pulled to move in the direction of the cross bar 23, the spring 27 is in a contracted state. The rebound force of the spring 27 can be used to quickly insert the sleeve 24 into the limiting hole 26, which is convenient for repeated use.

[0030] Reference Figure 6 As shown, in this embodiment: a sealing groove 28 is opened inside the shell 19 for use with the baffle 21. By providing the sealing groove 28, the sealing between the exhaust pipe 18 and the vacuum pump 20 can be ensured during the movement of the baffle 21, thereby avoiding gas leakage.

[0031] Working principle: The user turns the knob 11 to drive the rotating rod 10 to rotate inside the base 9 until the knob 11 no longer restricts the horizontal plate 7, and then rotates the horizontal plate 7 to drive the fixing rod 8 away from the furnace cover 3, making it easier for the user to open the furnace cover 3. After the furnace cover 3 is closed, the furnace cover 3 is reinforced by the above structure, which can significantly improve its structural stability and enable it to withstand greater pressure and impact. The wear resistance, erosion resistance and thermal shock resistance of the furnace cover 3 are enhanced, thereby extending the service life of the furnace cover 3 and reducing the damage caused by the furnace cover 3. The maintenance downtime caused by this is reduced, and the utilization rate and production efficiency of the furnace body 1 are improved. By setting the structure of the through groove 12 and the limit block 13, the vertical direction of the rotating rod 10 can be restricted to avoid tilting. At the same time, the threaded connection between the rotating rod 10 and the base 9 will not change without the action of external force. By setting the structure of the receiving seat 14, the annular groove 15 and the annular block 16, when the furnace cover 3 is closed, a seal is formed between the annular block 16 and the annular groove 15, which reduces the loss of heat and the leakage of gas in the furnace body 1. It helps to maintain the temperature stability in the furnace body 1, improve the smelting efficiency, and reduce energy consumption. At the same time, good sealing performance can also reduce the pollution of the furnace body 1 gas and improve the working environment. By setting the inner cavity 17, a vacuum zone can be formed between the smelting chamber and the furnace body 1, further improving energy consumption and avoiding heat loss. By setting the exhaust pipe 18 and connecting it to the inner cavity 17, the sleeve 24 is pulled toward the cross bar 23 to move the sleeve 24 out of the inside of the limit hole 26, and the cross bar 23 can be pulled to drive the connecting rod 22 to move the baffle 21 upward. Pull, and use the vacuum pump 20 to extract the gas inside the inner cavity 17 to form a vacuum, thereby avoiding heat loss and improving the efficiency of heat use. By setting the spring 27, when the sleeve 24 is pulled to move in the direction of the cross bar 23, the spring 27 is in a contracted state, and the rebound force of the spring 27 can make the sleeve 24 quickly inserted into the interior of the limiting hole 26, which is convenient for reuse. By setting the sealing groove 28, the sealing between the exhaust pipe 18 and the vacuum pump 20 can be ensured during the movement of the baffle 21 to avoid gas leakage.
