[0030] like Figures 1-6As shown in the figure, an aluminum rod furnace according to one embodiment of the present invention includes a furnace body 1 and a heat exchange and purification device 2. An exhaust port 11 is provided on the furnace body 1. The heat exchange and purification device 2 is connected and communicates with the exhaust port 11. The heat exchange and purification device 2 includes a heat exchange structure 21, a filter structure 22, and an exhaust hopper 23. One end of the heat exchange structure 21 is connected and communicates with the exhaust port 11, the end of the heat exchange structure 21 away from the exhaust port 11 is connected and communicates with the filter structure 22, and the end of the filter structure 22 away from the heat exchange structure 21 is connected and communicates with the exhaust hopper 23. By setting up the heat exchange and purification device 2, the two major functions of heat exchange and purification are integrated, realizing effective treatment and energy recovery of the emitted gas, and improving the energy efficiency and environmental performance of the entire system. The heat exchange purification device 2 includes a heat exchange structure 21, a filter structure 22, and an exhaust hopper 23. The heat exchange structure 21 can efficiently recover the heat energy in the exhaust gas, which helps to reduce energy consumption and improve the thermal efficiency of the entire system. The filter structure 22 can remove harmful substances in the exhaust gas, which helps to reduce environmental pollution and protect the ecological environment. The exhaust hopper 23 helps to accelerate the exhaust of the gas, ensuring that the purified gas can leave the system quickly and avoid lingering inside the system.

[0031] As a preferred embodiment of this utility model, it may also have the following additional technical features: the heat exchange structure 21 includes a heat exchange tube 211, a water inlet pipe 212, a drain pipe 213, and an exhaust structure 214. One end of the heat exchange tube 211 is fixedly connected to the exhaust port 11, and the end of the heat exchange tube 211 away from the exhaust port 11 is fixedly connected to the filter structure 22. The water inlet pipe 212 is located on the end of the heat exchange tube 211 away from the furnace body 1 and is connected and communicates with the heat exchange tube 211. The drain pipe 213 is located on the end of the heat exchange tube 211 close to the furnace body 1 and is connected and communicates with the heat exchange tube 211. The exhaust structure 214 is located inside the heat exchange tube 211. One end of the exhaust structure 214 is communicated with the exhaust port 11, and the end of the exhaust structure 214 away from the exhaust port 11 is communicated with the filter structure 22. The mixed gas generated in the aluminum rod furnace enters the heat exchange tube 211 through the exhaust port 11. The gas flows inside the heat exchange tube 211 and exchanges heat with the inner wall of the heat exchange tube 211. After heat exchange, the gas continues to flow to the exhaust structure 214 and finally enters the filter structure 22 for purification. Cooling water or other cooling media enters the heat exchange tube 211 through the water inlet pipe 212. The cooling water flows inside the heat exchange tube 211 and absorbs the heat released by the gas. The heated cooling water flows out of the heat exchange tube 211 through the drain pipe 213 and enters the subsequent cooling system or is directly discharged.

[0032] As a preferred embodiment of this utility model, it may also have the following additional technical features: the exhaust structure 214 includes an exhaust pipe 2141 and a plurality of baffles 2142. Each baffle 2142 is equidistantly arranged within the exhaust pipe 2141, serving to turbulent the airflow and enhance heat exchange. The exhaust pipe 2141 is spirally arranged, increasing the flow path and residence time of the gas within the heat exchange tube 211, which helps to improve heat exchange efficiency and allows the gas to more fully exchange heat with the inner wall of the heat exchange tube 211. The exhaust pipe 2141 is disposed within the heat exchange tube 211 and fixedly connected to it. One end of the exhaust pipe 2141 is connected to the exhaust port 11, and the end of the exhaust pipe 2141 away from the exhaust port 11 is connected to the filter structure 22.

[0033] As a preferred embodiment of this utility model, it may also have the following additional technical features: the filter structure 22 includes a purification pipe 221 and a filter block 222. The filter block 222 is disposed inside the purification pipe 221. The purification pipe 221 is divided into an inlet section 2211, a filter section 2212, and an exhaust section 2213 from bottom to top. The inlet section 2211 is connected to the heat exchange structure 21 via a flange joint, and the exhaust section 2213 is connected to the exhaust hopper 23 via a flange joint. The filter block 222 is disposed inside the filter section 2212. The inlet section 2211 is connected and communicates with the heat exchange structure 21, and the exhaust section 2213 is connected and communicates with the exhaust hopper 23. Gas enters from the inlet section 2211, is purified by the filter section 2212, and is finally discharged from the exhaust section 2213, which helps to reduce the resistance of the gas during the purification process and improve the purification efficiency.

[0034] As a preferred embodiment of this utility model, it may also have the following additional technical features: An opening is provided on the side wall of the filter section 2212; a closing door 2214 for controlling the opening and closing is installed on the filter section 2212; the closing door 2214 is movably connected to the purification tube 221; a slide rail 2215 extending along the direction of the opening is fixedly connected inside the filter section 2212; the filter block 222 is slidably connected to the slide rail 2215; and the filter block 222 can slide radially along the filter section 2212 guided by the slide rail 2215. When the filter block 222 becomes clogged or fails, it can be quickly replaced without replacing the entire purification tube 221. The position and size of the opening can be adjusted according to actual needs to accommodate filter blocks 222 of different sizes and operational requirements.

[0035] As a preferred embodiment of this utility model, it may also have the following additional technical features: one side of the closed door 2214 is hinged to the open side via a hinge 2216, realizing the flexible opening and closing of the closed door 2214, allowing the closed door 2214 to rotate smoothly along the edge of the opening without jamming or loosening. A latch 2217 is installed on the side of the closed door 2214 away from the hinge 2216 to lock the position of the closed door 2214. A socket 2218 is provided on the side of the opening away from the hinge 2216, and the latch 2217 is compatible with the socket 2218. When the closed door 2214 is closed, the latch 2217 can be inserted into the socket 2218 to achieve a tight lock. In this embodiment, a sealing element is provided on the outer periphery of the closed door 2214 to ensure sealing when closed.

[0036] As a preferred embodiment of this utility model, it may also have the following additional technical features: a handle 2219 is provided on the closing door 2214, and the handle 2219 is fixedly connected to the closing door 2214, providing users with a convenient opening and closing operation point.

[0037] In a preferred embodiment of this utility model, it may also have the following additional technical features: the filter block 222 is configured as an activated carbon block.

[0038] As a preferred embodiment of this utility model, it may also have the following additional technical features: the radius of the air inlet section 2211 gradually decreases from the end away from the heat exchange structure 21 to the end closer to the heat exchange structure 21, and the radius of the exhaust section 2213 gradually decreases from the end away from the exhaust hopper 23 to the end closer to the exhaust hopper 23. The gradual change in diameter helps to reduce eddies and resistance generated during gas flow. The reduction of eddies and resistance can improve gas purification efficiency while reducing energy loss.

[0039] As a preferred embodiment of this utility model, it may also have the following additional technical features: the radius of the exhaust hopper 23 is gradually reduced from the end away from the heat exchange structure 21 to the end closer to the heat exchange structure 21, which can guide the gas to flow along a specific path, avoid the gas from generating eddies or stagnation inside the exhaust hopper 23, and improve the exhaust efficiency.

[0040] The working principle of the aluminum rod furnace in this embodiment is as follows: The aluminum rods are heated inside the furnace body 1 to generate a mixed gas. The mixed gas enters the heat exchange and purification device 2 through the exhaust port 11 on the furnace body 1. In the heat exchange structure 21, the gas first enters the heat exchange tube 211. Cooling water or other cooling medium enters the heat exchange tube 211 through the water inlet pipe 212 and exchanges heat with the gas. The heat released by the gas is absorbed by the cooling water, and the heated cooling water flows out of the heat exchange tube 211 through the drain pipe 213. The gas that has undergone heat exchange continues to flow to the exhaust structure 214 and finally enters the filter structure 22. The gas enters the purification pipe 221 from the gas inlet section 2211 and is purified through the filter section 2212. The purified gas is discharged from the exhaust section 2213 and enters the exhaust hopper 23.

[0041] The aluminum rod furnace in this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other equipment with similar usage requirements. In this embodiment, the aluminum rod furnace can effectively purify the high-temperature mixed gas generated by the aluminum rod furnace, ensuring air quality.
