The filter box 10 can filter the smoke entering the housing 9 through the air inlet pipe 8 to prevent impurities in the smoke from moving out of the housing 9, thereby preventing impurities from polluting the air. A baffle 19 is fixedly connected to one side of the filter box 10. The baffle 19 and the housing 9 are plug-fitted. The baffle 19 can block the gap between the housing 9 and the filter box 10, thereby improving the sealing between the housing 9 and the filter box 10, thereby preventing smoke leakage.
[0033] Reference Figure 2-Figure 4A clamping assembly is fixedly connected to the outside of the shell 9, a pad 11 is fixedly connected to the inside of the shell 9, a heat storage stone 12 is fixedly connected to the top of the pad 11, an exhaust pipe 13 is fixedly connected to the rear side of the shell 9, and a solenoid valve 14 is fixedly connected to the middle of the exhaust pipe 13. The filtered flue gas can be discharged through the exhaust pipe 13, and the heat in the flue gas can be absorbed by the heat storage stone 12 during the discharge. A connecting pipe 15 is fixedly connected to the outside of the shell 2, and the other end of the connecting pipe 15 is fixedly connected to the rear side of the shell 2. A one-way valve 16 is fixedly connected to the middle of the air inlet pipe 8 and the connecting pipe 15. After use is completed and when it needs to be used again, the filtered flue gas can pass through the heat storage stone 12 and enter the shell 2 through the connecting pipe 15 by closing the solenoid valve 14, and then the flue gas can be heated by the heat emitted by the heat storage stone 12, which can accelerate the increase of the temperature inside the shell 2, while avoiding heat loss and reducing the cost of using a crucible furnace.
[0034] Reference Figure 2 and Figure 4 The clamping assembly includes a connecting block 20, which is fixedly connected to the outer side of the shell 9, and a compression spring 22 is fixedly connected to the inside of the connecting block 20. A T-bar 21 is slidably connected to the middle part of the connecting block 20, and the end of the T-bar 21 away from the connecting block 20 is fixedly connected to a clamping plate 23, and the side of the clamping plate 23 close to the T-bar 21 is fixedly connected to a rubber pad 24, and the rubber pad 24 is in contact with the baffle 19, and the other end of the compression spring 22 is in contact with the side of the T-bar 21 close to the clamping plate 23. By pulling the T-bar 21 and rotating the T-bar 21, the compression spring 22 will be compressed when the T-bar 21 is pulled. At the same time, when the T-bar 21 rotates until the clamping plate 23 is not on the front side of the baffle 19, it can contact the restriction of the baffle 19, and then the filter box 10 can be easily taken out. By pulling the T-bar 21 and rotating it in the opposite direction until the clamping plate 23 moves to the front side of the baffle 19, the T-bar 21 is released and the clamping plate 23 can drive the rubber pad 24 to squeeze the baffle 19 under the action of the compression spring 22, so that the rubber pad 24 can fix the filter box 10.
[0035] Reference Figure 3 The flip assembly includes a connecting plate 7, which is installed on the outside of the container 5.

The baffle 19 is fixedly connected to the side close to the filter box 10 with a sealing gasket 25. The middle part of the housing 2 is provided with a sealing groove 26. The sealing gasket 25 and the sealing groove 26 are plugged in and matched. The cooperation between the sealing gasket 25 and the sealing groove 26 can further improve the sealing performance of the housing 9 and prevent smoke leakage.
[0037] Working principle: When in use, the exhaust smoke enters the shell 9 through the air inlet pipe 8. At this time, the incoming smoke can be filtered under the action of the filter box 10, and the heat in the smoke can be absorbed and stored under the action of the heat storage stone 12. Finally, the smoke is discharged through the exhaust pipe 13. When used again, the exhaust pipe 13 can be closed by opening the solenoid valve 14. Under the action of the connecting pipe 15, the filtered smoke can re-enter the shell 2, which can quickly heat up the inside of the shell 2.
[0038] By pulling the T-bar 21 and rotating it, the compression spring 22 will be compressed when the T-bar 21 is pulled, and when the T-bar 21 rotates until the clamping plate 23 is not in front of the baffle 19, the filter box 10 can be taken out. By pulling the T-bar 21 and rotating it in the opposite direction until the clamping plate 23 moves to the front of the baffle 19, the T-bar 21 is loosened and the clamping plate 23 drives the rubber pad 24 to squeeze the baffle 19 under the action of the compression spring 22, so that the rubber pad 24 can fix the baffle 19.
[0039] Finally, by driving the worm 17 , the worm wheel 18 can drive the container 5 to tilt, so that the melted material in the container 5 can be easily poured out, and at the same time, the poured material can be discharged from the housing 2 under the action of the drainage groove 27 .
