[0022] The cross-sectional shape of the curved pipe 3 is set to a spiral shape, the water tank 4 and the exhaust pipe 2 are fixedly connected, and the outer wall of the stirring rod 5 is connected to the lower end of the outer wall of the transmission rod 8 through a sprocket mechanism, so as to increase the contact area between the curved pipe 3 and the cooling water, so that the cooling water can fully absorb the thermal resources in the exhaust gas, and it is convenient to improve the stability of the device, and at the same time, it is convenient for the motor 7 to drive the transmission rod 8 to rotate the stirring rod 5, so that the stirring rod 5 stirs the hot water to avoid uneven heating of the hot water affecting its use.

[0023] The exhaust mechanism 10 includes a wind rod 1001 and an exhaust fan 1002, and the wind rod 1001 is installed on the inner wall of the air duct 9, and the exhaust fan 1002 is fixedly connected to the outer wall of the lower end of the wind rod 1001, so as to accelerate the flow rate of the gas inside the device through the exhaust mechanism 10, thereby improving the exhaust gas treatment efficiency.

[0027] Working principle: When using the environmentally friendly exhaust pipe device for lost foam casting, first Figure 1-2As shown, the user injects cooling water into the water tank 4 through the water injection port provided at the upper end of the water tank 4, and then when the high-temperature exhaust gas generated by the lost foam casting enters the air inlet pipe 1, the user starts the motor 7, and at this time the motor 7 drives the transmission rod 8 so that the transmission rod 8 drives the wind rod 1001 to rotate through the sprocket mechanism, and then the wind rod 1001 drives the exhaust fan 1002 to rotate so that the exhaust fan 1002 blows the gas inside the device out of the device through the air outlet pipe 11 to enter the next process, so that the exhaust gas flows quickly inside the device, and at this time the exhaust gas enters the device through the air inlet pipe 1, and then passes through the exhaust pipe 11 to enter the next process. The exhaust gas passes through the elbow 3, the exhaust pipe 2, the filter box 6, the air duct 9 and the exhaust pipe 11 to discharge the device. Then, when the exhaust gas enters the filter box 6, the filter 13 filters the particulate impurities in the exhaust gas. At the same time, the high-temperature exhaust gas dissipates heat through the elbow 3. At this time, the cooling water absorbs the heat to utilize the thermal resources in the exhaust gas. With the start of the motor 7, the transmission rod 8 drives the stirring rod 5 to rotate through the sprocket mechanism, so that the stirring rod 5 stirs the hot water, which facilitates the uniform distribution of heat in the hot water and avoids the uneven heating of the hot water affecting the use. When the filter 13 needs to be cleaned, Figure 1-4 As shown, stop introducing exhaust gas into the device, then the user rotates the knob 18, then the knob 18 is disengaged from the relative positioning plate 17 and the ferrule 19, then the user rotates to open the cover 15 so that the cover 15 drives the sealing gasket 16 to disengage from the filter box 6, then the user holds the handle 14, and then the user pulls out the filter frame 12 in the filter box 6, thereby completing the disassembly of the filter 13. Therefore, the device is convenient for disassembling the filter 13 for cleaning, thereby avoiding the accumulation of impurities on the filter 13 that affect the use effect.
