[0003] And aluminum material is easy to recycle, so after use, it can be crushed into small pieces and smelted, the pollutants and coatings on the surface of the aluminum material are removed, and the shape is reshaped to become new aluminum products. When recycling and smelting aluminum material, a smelting furnace is generally used for smelting. When smelting aluminum material, the exhaust gas temperature of the smelting furnace is high. In order to utilize the heat energy, a preheating kiln is generally installed in the exhaust gas pipeline. New aluminum material is placed in the preheating kiln. When the smelting furnace smelts the aluminum material, the high-temperature exhaust gas passes through the aluminum material in the preheating kiln through the exhaust gas pipeline, and preheats the aluminum material in the preheating kiln, so that the efficiency of smelting the aluminum material in the preheating kiln is higher.
[0004] However, in actual use, the temperature of the high-temperature exhaust gas is still very high after preheating the aluminum material, and the preheating efficiency of the aluminum material is low due to the small heat capacity of the exhaust gas.

[0037] Combining the drawings Figure 3 , Figure 7 , Figure 8 and Figure 9As shown, the top of the top frame 42 is fixedly connected with several installation pipes 5, the bottom end of the installation pipe 5 is communicated with the corresponding position of the sliding groove 43 on the top frame 42, the top end of the installation pipe 5 is fixedly connected with the annular exhaust disc 51, the exhaust disc 51 is communicated with the installation pipe 5, the top of the exhaust disc 51 is provided with an arc-shaped air guide groove 52, the top of the top frame 42 is fixedly connected with the annular water tank 6 through the frame body, the water tank 6 is located above the exhaust disc 51, the water tank 6 is connected with the automatic water supplement mechanism, the top of the water tank 6 is fixedly connected with the steam pipe 61, the end of the steam pipe 61 away from the water tank 6 penetrates the preheating kiln 31 and extends to the outside, the side of the steam pipe 61 is fixedly connected with the installation box 62 which is communicated with each other, the installation rod 63 is rotatably connected in the installation box 62, the bottom end of the installation rod 63 penetrates the bottom of the installation box 62, the side wall close to the top end of the installation rod 63 is fixedly connected with several evenly distributed baffles 64, the baffle 64 is located in the installation box 62, the steam pipe 61 is provided with the air baffle 65 close to the installation box 62, the air baffle 65 is made of soft material, in the process of blocking the steam, the baffle 64 can directly push away the air baffle 65 in the rotating process, and after the baffle 64 passes through the air baffle 65, the air baffle 65 will rebound to the initial state, avoiding the problem that the air baffle 65 blocks the baffle 64 in the process of blocking the steam, causing the baffle 64 to be unable to rotate normally, the side wall close to the bottom end of the installation rod 63 is fixedly connected with several fixed springs 66, the end of the fixed spring 66 away from the installation rod 63 is fixedly connected with the hammer head 67, the side of the preheating kiln 31 close to the installation rod 63 is fixedly connected with the fixed frame 68, the installation rod 63 is rotatably installed on the fixed frame 68, the fixed ring 8 is fixedly connected between the air guide pipes 47, the side of the fixed ring 8 close to the installation rod 63 is fixedly connected with the connecting rod 81, the end of the connecting rod 81 away from the fixed ring 8 penetrates the preheating kiln 31 and is fixedly connected with the butt joint 82, the butt joint 82 is located on one side of the installation rod 63.
[0038] Further, after the high-temperature exhaust gas passes through the gas guide pipe 47, the high-temperature exhaust gas is transported into each mounting pipe 5 by the chute 43 of the top frame 42 and the communication groove 46 of the mounting seat 44 in the chute 43, and the high-temperature exhaust gas is discharged through the exhaust disc 51. At this time, the high-temperature exhaust gas heats the water tank 6 above the exhaust disc 51, causing the water in the water tank 6 to evaporate into water vapor. The water vapor moves towards the mounting box 62 through the steam pipe 61. At this time, the steam pipe 61 is provided with a gas baffle 65, so the steam moves along the mounting box 62 and pushes the baffle 64 to move, thereby completing the rotation of the mounting rod 63. At this time, the mounting rod 63 rotates with the fixed spring 66 and the hammer head 67, and the rotating hammer head 67 constantly strikes the joint 82 and transmits the striking force to the fixed ring 8 through the connecting rod 81, driving the gas guide pipe 47 and the mounting seat 44 to displace. The mounting seat 44 can contract and stretch the limiting springs 45 on both sides during displacement, and the rebounding characteristics of the limiting springs 45 drive the mounting seat 44 and the gas guide pipe 47 to move back and forth along the chute 43, thereby achieving the vibration of the gas guide pipe 47. During the vibration, the gas guide pipe 47 can displace the aluminum material in contact with it, so that the aluminum materials at different positions can be in contact with the gas guide pipe 47 in turn, avoiding the problem of uneven preheating caused by the long-term contact of the aluminum materials at the same position with the gas guide pipe 47. At the same time, during the transportation of the aluminum materials in the preheating kiln 31 into the smelting furnace 11, the constantly vibrating gas guide pipe 47 can scatter the aluminum materials accumulated on the chassis 41, avoiding the problem of not easily sliding into the smelting furnace 11 along the guide slope of the chassis 41. After the water vapor pushes the baffle 64 to rotate, it continues to enter the subsequent steam pipe 61. At this time, the steam can be used for heating and other work, improving the utilization efficiency of heat energy. The automatic water replenishing mechanism includes a water pump, a water delivery pipe, a water level sensor and other components, which are all prior art means, so they will not be described in detail.
[0039] Combining the drawings Figure 8 , Figure 9 and Figure 10 As shown, the steam pipe 61 is fixedly connected with an airtight box 7 that is in communication with each other. The airtight box 7 is rotatably connected with a sealing plate 71. The airtight box 7 is fixedly connected with a mounting ring 72 on both sides. The shaft rod on both sides of the sealing plate 71 is fixedly connected with a torsional spring 73 between the inner wall of the mounting ring 72 on the same side.
[0040] Further, by the cooperation of the air-tight box 7 and the sealing plate 71, the steam pipe 61 can be blocked, so that the water vapor in the water tank 6 is continuously gathered, thereby increasing the air pressure in the water tank 6. When the air pressure in the water tank 6 exceeds the contraction threshold of the torsion spring 73, the water vapor will push open the air-tight box 7 and enter the subsequent steam pipe 61 and mounting box 62 at a high speed and impact force. At this time, the water vapor with improved speed and impact force can better push the baffle 64 to rotate. When the water vapor in the water tank 6 is discharged to a certain amount, the air pressure in the water tank 6 is lowered, the torsion spring 73 starts to rebound, and the sealing plate 71 is reset. At this time, the steam pipe 61 can be blocked again, and the water vapor can be gathered in the water tank 6 again.
[0041] Working principle: during the smelting process of the aluminum material in the smelting furnace 11, the inlet of the smelting furnace 11 is connected with the exhaust pipe 32, then the new aluminum material is put into the feeding pipe 34, at this time, the valve of the feeding pipe 34 and the hopper 410 is opened, the aluminum material in the feeding pipe 34 will enter the preheating kiln 31 through the feeding pipe 34 and the hopper 410, and fall on the bottom frame 41, then the valve of the feeding pipe 34 and the hopper 410 is closed, after the crushed aluminum material is transported into the smelting furnace 11, the gas pipe 22 is used to transport the gas into the combustion head 21, at this time, the combustion head 21 ignites the gas by the built-in ignition mechanism, and uses the ejected flame to smelt the aluminum material in the smelting furnace 11;
[0042] At this time, the high-temperature exhaust gas generated in the aluminum smelting process will enter the exhaust pipe 32, and then enter the preheating kiln 31 along the exhaust pipe 32, and preliminarily preheat the aluminum material in the preheating kiln 31, and then the high-temperature exhaust gas will enter the return air pipe 4 through the preheating kiln 31, and then enter the gas guide pipe 47 along the return air pipe 4, the connecting pipe 48 and the connecting groove 46 on the mounting seat 44 in the slide groove 43 on the bottom frame 41. At this time, the heat conduction performance of the gas guide pipe 47 can be used to preheat the aluminum material in the preheating kiln 31 twice, and at the same time, since the gas guide pipe 47 is annularly distributed near the inner wall of the preheating kiln 31, it can heat the aluminum material near the inner wall of the preheating kiln 31, and also provide heat preservation for the aluminum material in the preheating kiln 31. When the aluminum smelting in the smelting furnace 11 is completed, the driving mechanism in the mounting column 2 drives the combustion head 21 to rotate away from the combustion port of the smelting furnace 11, and the transmission mechanism on the supporting seat 1 drives the smelting furnace 11 to rotate, so that one end of the combustion port is at the low position, and the other end of the inlet is at the high position and is connected with the discharge pipe 33. At this time, the discharge port 12 is opened, and the molten aluminum in the smelting furnace 11 is discharged. Then the discharge port 12 is closed, and then the valve on the discharge pipe 33 is opened. At this time, the preheated aluminum material in the preheating kiln 31 will slide down along the top of the bottom frame 41 with a guide slope into the smelting furnace 11. When the aluminum material in the preheating kiln 31 enters the smelting furnace 11, the transmission mechanism on the supporting seat 1 drives the smelting furnace 11 to return to the normal position, and the inlet of the smelting furnace 11 is connected with the exhaust pipe 32. Then the driving mechanism in the mounting column 2 drives the combustion head 21 to rotate, so that the combustion head 21 is connected with the combustion port of the smelting furnace 11. Then the valve on the discharge pipe 33 is closed, and the smelting of the aluminum material is continued, and the valves of the feeding pipe 34 and the lower hopper 410 are opened, so that new aluminum material enters the preheating kiln 31 for preheating work;
