Description

Technical Field

[0001] This application relates to the field of smelting furnaces, and more particularly to a smelting furnace and smelting equipment. Background Technology

[0002] In the field of metal smelting, the heating method of smelting equipment directly affects production efficiency and energy consumption. Traditional equipment typically uses a bottom-concentrated heating mode, resulting in severe localized heating of the smelting vessel and an inability to evenly transfer heat to the entire smelting medium. This uneven heating not only causes low heat conduction efficiency and slow temperature rise, but also prolongs the smelting cycle. Although existing technologies attempt to alleviate these problems by improving insulation materials or optimizing burner layout, the fundamental defects of uneven heat distribution due to the single heating path remain unresolved, making it difficult to achieve a rapid and uniform smelting process. Utility Model Content

[0024] This application provides a smelting furnace 100 having a first direction Z and a first plane P perpendicular to the first direction Z. The smelting furnace 100 includes a furnace body 110, a first partition 120, a second partition 130, a first tube 140, and a second tube 150.

[0025] Specifically, the furnace body 110 has a furnace cavity 101 for accommodating a melting vessel (not shown). A first partition 120 is disposed within the furnace cavity 101 along a first direction Z, dividing the furnace cavity 101 into a first cavity 111 and a second cavity 112. A second partition 130 includes a first separator 131 and a second separator 132 connected to the inner wall of the furnace cavity 101 and disposed along a first plane P. The first separator 131 is disposed within the first cavity 111 and divides the first cavity 111 into a first channel 1. The first cavity 1111 and the second cavity 1112 are partially connected. The second partition 132 is disposed in the second cavity 112 and divides the second cavity 112 into a third cavity 1121 and a fourth cavity 1122. The third cavity 1121 and the fourth cavity 1122 are partially connected. The first tube 140 is connected to the furnace body 110 and is connected to the first cavity 1111. The second tube 150 is connected to the furnace body 110 and is connected to the fourth cavity 1122.

[0026] For example, the melting vessel described above can be a crucible, a vessel capable of melting metal.

[0027] In this embodiment, the first direction Z is the vertical direction, the first plane P is the horizontal plane, and the melting container is in contact with the first partition 120, the first partition 131, and the second partition 132.

[0028] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, a first partition 120 is vertically arranged at the middle position of the furnace cavity 101 along the vertical direction, and the first partition 120 is connected to the peripheral side wall of the furnace cavity 101. The first partition 120 divides the furnace cavity 101 into a first cavity 111 and a second cavity 112. Further, in the horizontal direction, a first partition 131 is arranged in the first cavity 111, and the first partition 131 divides the first cavity 111 into a first channel 1111 and a second channel 11. 12, and the first cavity 1111 and the second cavity 1112 are partially connected; a second partition 132 is provided in the second cavity 112, the second partition 132 divides the second cavity 112 into a third cavity 1121 and a fourth cavity 1122, the third cavity 1121 and the fourth cavity 1122 are partially connected, so that the first cavity 1111, the second cavity 1112, the third cavity 1121 and the fourth cavity 1122 can be connected to form a combustion channel.

[0029] Please continue reading. Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the first partition 120 is divided into a bottom partition and a side partition. The bottom of the melting container is in contact with the bottom partition of the first partition 120, and the peripheral wall of the melting container is in contact with the side partition of the first partition 120, as well as the first partition 131 and the second partition 132. Therefore, the first cavity 1111, the second cavity 1112, the third cavity 1121 and the fourth cavity 1122 are separated and made independent under the isolation of the melting container to prevent the heat generated by combustion from escaping to different spaces.

[0030] Specifically, at this time, the first cavity 1111, the second cavity 1112, the fourth cavity 1122, and the third cavity 1121 are connected to form a combustion path, which heats the bottom and the surrounding wall of the melting container to melt the object. It can be understood that this combustion path prolongs the time that the high-temperature flame or high-temperature gas is in the furnace cavity 101, thereby increasing the time for heat exchange with the melting container. This allows the heat energy generated by combustion to be fully transferred to the melting container, thereby heating the object located in the melting container and improving the utilization rate of heat energy.

[0031] For example, the furnace body 110, the first partition 120, the first partition 131 and the second partition 132 can be formed by stacking refractory materials such as refractory bricks or refractory concrete.

[0032] In some embodiments, one end of the first partition 131 is connected to the first partition 120, and the other end of the first partition 131 forms a first channel 1311 with the first partition 120. The first cavity 1111 and the second cavity 1112 are connected through the first channel 1311. One end of the second partition 132 is connected to the first partition 120, and the other end of the second partition 132 forms a second channel 1321 with the first partition 120. The first channel 1311 and the second channel 1321 are disposed on the same side, and the third cavity 1121 and the fourth cavity 1122 are connected through the second channel 1321.

[0033] Please continue reading. Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the second cavity 1112 is connected to the fourth cavity 1122. In order to connect the first cavity 1111 to the second cavity 1112, one end of the first partition 131 is not connected to the side isolation portion of the first partition 120. For this purpose, a first channel 1311 is formed between the first partition 131 and the side isolation portion of the first partition 120. The first cavity 1111 is connected to the second cavity 1112 through the first channel 1311. Similarly, one end of the second partition 132 is not connected to the side isolation portion of the first partition 120 to form a second channel 1321. The third cavity 1121 is connected to the fourth cavity 1122 through the second channel 1321.

[0034] Furthermore, taking the first tube 140 for ignition and the second tube 150 for gas outlet as an example, the first channel 1311 and the second channel 1321 are set on the same side. Therefore, the flame or high-temperature gas formed by combustion will inevitably pass through the first channel 1311 → the second cavity 1112 → the fourth cavity 1122 → the second channel 1321, thereby further extending the time of the flame or high-temperature gas in the furnace cavity 101 and further increasing the heat exchange time with the melting vessel.

[0035] In this embodiment, if the first tube 140 is used for air intake ignition, then the second tube 150 is used for air output. If the second tube 150 is used for air intake ignition, then the first tube 140 is used for air output. In practice, air intake ignition can be selected as needed, and there is no limitation here.

[0036] See Figure 5As shown, if the melting vessel is heated by igniting the first tube 140 and venting the second tube 150, the path of the flame and high-temperature gas generated by the combustion of the first tube 140 is as follows: first tube 140 → first cavity 1111 → first channel 1311 → second cavity 1112 → fourth cavity 1122 → second channel 1321 → third cavity 1121 → second tube 150.

[0037] See Figure 6 As shown, if the melting vessel is heated by igniting the second tube 150 and venting the first tube 140, the path of the flame and high-temperature gas generated by the combustion of the second tube 150 is as follows: second tube 150 → third cavity 1121 → second channel 1321 → fourth cavity 1122 → second cavity 1112 → first channel 1311 → first cavity 1111 → first tube 140.

[0038] This embodiment also provides a smelting device, which includes a smelting furnace, a first heat storage box 200, a second heat storage box 300, a switching valve 400, and a blower 500, wherein the first heat storage box 200 is connected to the first cavity 1111.

[0039] Specifically, the second thermal storage box 300 is connected to the third cavity 1121, the switching valve 400 is connected to the first thermal storage box 200 and the second thermal storage box 300 respectively, and the fan 500 is connected to the switching valve 400. The switching valve 400 is used to switch the connection or disconnection between the first thermal storage box 200, the second thermal storage box 300 and the fan 500.

[0040] See Figure 7As shown, to prevent the heat from the exhaust gas from the smelting furnace 100 from being directly discharged to the outside and wasting resources, the first heat storage box 200 is connected to the first cavity 1111 and the second heat storage box 300 is connected to the third cavity 1121. This allows the heat from the exhaust gas to be absorbed through the first and second heat storage boxes 200 and 300, maximizing heat utilization. It can be understood that when heat from the first and second heat storage boxes 200 and 300 is needed, for example, when the first pipe 140 is ignited, the fan 500 can be connected to the first heat storage box 200 through the switching valve 400. At this time, the fan 500 is disconnected from the second heat storage box 300. External air is transferred to the first heat storage box 200. The heat storage medium in the first heat storage box 200 will reheat the gas from the blower 500 and deliver it to the first cavity 1111, thereby realizing the utilization of the thermal energy stored in the first heat storage box 200. Similarly, when the second tube 150 is ignited and combustion is required, the heat stored in the second heat storage box 300 is needed. The blower 500 is connected to the second heat storage box 300 through the switching valve 400. At this time, the blower 500 delivers external air to the second heat storage box 300. The heat storage medium in the second heat storage box 300 will reheat the air from the blower 500. The heated air will re-enter the third cavity 1121 to heat the melting container.

[0041] It is understandable that by supplying hot air to the first cavity 1111 or the third cavity 1121 through the fan 500, the oxygen content inside can be increased, making the fuel more complete and ensuring full combustion, thereby improving the utilization rate of the fuel and preventing fuel waste caused by incomplete combustion.

[0042] In some embodiments, the furnace body 110 is further provided with a third tube 141 and a fourth tube 151. The third tube 141 is connected to the first cavity 1111 and is located on the same side as the first tube 140. The fourth tube 151 is connected to the third cavity 1121 and is located on the same side as the second tube 150. The first heat storage box 200 is connected to the third tube 141, and the second heat storage box 300 is connected to the fourth tube 151.

[0043] Please see Figure 1 , Figure 2 , Figure 5 as well as Figure 6 As shown, in order to connect the first heat storage box 200 with the first cavity 1111, a third pipe 141 is provided between the first heat storage box 200 and the first cavity 1111 to achieve the connection. Similarly, in order to connect the second heat storage box 300 with the third cavity 1121, a fourth pipe 151 is provided between the second heat storage box 300 and the third cavity 1121 to achieve the connection, thereby realizing the transportation of high temperature gas.

[0044] In some embodiments, the switching valve 400 includes a valve body 410, which includes a first connection port 420, a second connection port 430, an air inlet 440, and an exhaust port 450. The first connection port 420 is connected to the first thermal storage box 200, the second connection port 430 is connected to the second thermal storage box 300, and the air inlet 440 is connected to the fan 500. The valve body 410 controls the air inlet 440 and the first connection port 420 to communicate and the second connection port 430 to communicate with the exhaust port 450; or, the valve body 410 controls the air inlet 440 and the second connection port 430 to communicate and the first connection port 420 to communicate with the exhaust port 450.

[0045] Please see Figure 8 , Figure 9 as well as Figure 10 As shown, when the first pipe 140 is ignited and combusted, the exhaust gas is transported to the second heat storage box 300 through the fourth pipe 151. At the same time, the valve body 410 switches to connect the first connection port 420 with the air inlet 440 and the second connection port 430 with the outlet 450. After the exhaust gas enters the second heat storage box 300, it re-enters the second heat storage box 300 through the exhaust gas from the fourth pipe 151 and absorbs and stores the heat in the exhaust gas through the heat storage medium in the second heat storage box 300. Finally, the exhaust gas that can no longer store heat is discharged to the outside through the outlet 450. At the same time, the fan 500 transports the outside air to the first heat storage box 200 through the first connection port 420, so that the heat in the heat storage medium in the first heat storage box 200 heats the air from the fan 500. Finally, the heated air is transported to the first cavity 1111 through the third pipe 141 to heat the melting container.

[0046] Please see Figure 8 , Figure 11 and Figure 12 As shown, when the second pipe 150 is ignited and combusted, the exhaust gas is transported to the first heat storage box 200 through the third pipe 141. At the same time, the valve body 410 switches to connect the second connection port 430 with the air inlet 440 and the first connection port 420 with the exhaust port 450. After the exhaust gas enters the first heat storage box 200, the exhaust gas from the third pipe 141 will re-enter the first heat storage box 200 and absorb and store the heat in the exhaust gas through the heat storage medium in the first heat storage box 200. Finally, the exhaust gas that can no longer store heat is discharged to the outside through the exhaust port 450. At the same time, the fan 500 transports the outside air to the second heat storage box 300 through the second connection port 430, so that the heat in the heat storage medium in the second heat storage box 300 heats the air from the fan 500. Finally, the heated air is transported to the third cavity 1121 through the fourth pipe 151 to heat the melting container.

[0047] In some embodiments, temperature sensors are provided on both the first connection port 420 and the second connection port 430.

[0048] Specifically, in order to enable the reuse of the thermal energy stored in the first thermal storage tank 200 and the second thermal storage tank 300, temperature sensors located at the first connection port 420 and the second connection port 430 are used to detect the temperature of the thermal energy stored in the first thermal storage tank 200 and the second thermal storage tank 300. For example, if the temperature sensor detects that the temperature at the first connection port 420 has reached the preset temperature, the valve body 410 connects the first connection port 420 to the air inlet 440, and the first pipe 140 is ignited. Correspondingly, the exhaust port 450 is connected to the second connection port 430, and the second pipe 150 is not ignited. The exhaust gas enters the second heat storage box 300 through the fourth pipe 151 for heat storage, and finally the exhaust gas is discharged to the outside through the exhaust port 450. If the temperature sensor detects that the temperature at the second connection port 430 has reached the preset temperature, the valve body 410 connects the second connection port 430 with the air inlet 440, and the second pipe 150 is ignited. Correspondingly, the first connection port 420 is connected with the exhaust port 450. At this time, the first pipe 140 is not ignited, and the exhaust gas enters the first heat storage box 200 through the third pipe 141 for heat storage, and finally the exhaust gas is discharged to the outside through the exhaust port 450. This cycle is repeated to maximize the utilization of thermal energy.

[0049] See Figure 9 , Figure 10 , Figure 11 as well as Figure 12 As shown, the first heat storage box 200 includes a first box body 210, the first box body 210 having a first box cavity 211, and a first heat storage medium 220 disposed inside the first box cavity 211. The second heat storage box 300 includes a second box body 310, the second box body 310 having a second box cavity 311, and a second heat storage medium 320 disposed inside the second box cavity 311.

[0050] The heat in the waste gas is absorbed by the first heat storage medium 220 and the second heat storage medium 320 to achieve heat energy storage.

[0051] In this embodiment, both the first heat storage medium 220 and the second heat storage medium 320 are honeycomb bricks. In practice, other heat storage media can also be used to store heat, but this is not limited here.
