The outer wall of the rack 8 is slidably connected with a sliding bottom column 9. The lower surface of the sliding bottom column 9 is fixedly connected to the upper surface of the base 1. The upper outer wall of the rack 8 is fixedly connected with a bracket 10. The outer wall of the bracket 10 is fixedly connected with a first sleeve 11. The lower surface of the first sleeve 11 is fixedly connected with an air collecting hood 12. The inner wall of the first sleeve 11 is fixedly connected with a telescopic pipe 13. The top of the telescopic pipe 13 is provided with a gas guiding assembly for guiding the waste gas transportation.

[0023] Specifically, when melting aluminum ingots in a furnace, a large amount of dust and smoke will be generated. An air collecting hood 12 is arranged above the aluminum ingot furnace 28 to converge the flue gas. The first motor 2 is started to drive the first bevel gear 3 at the output end to rotate. The first bevel gear 3 drives the second bevel gear 4 to rotate, thereby driving the transmission shaft 5 to rotate. The transmission shaft 5 drives the transmission gears 7 on both sides to rotate. The transmission gear 7 meshes with the rack 8. When the transmission gear 7 rotates, it drives the rack 8 to slide up and down in the sliding bottom column 9. The first sleeve 11 follows the rack 8 to lift and lower through the bracket 10. When the first sleeve 11 lifts and lowers and drives the upper telescopic pipe 13 to expand and contract, it also drives the air collecting hood 12 to lift and lower.

[0024] Referring to Figure 1 and Figure 3 , the air guiding assembly includes a second sleeve 14. The inner wall of the second sleeve 14 is fixedly connected to the top end of the telescopic pipe 13. The upper surface of the second sleeve 14 is fixedly connected to an air guiding pipe 15. The outer wall of the second sleeve 14 is fixedly connected to a fixing frame 27. The lower surface of the fixing frame 27 is fixedly connected to the upper surface of the base 1. The outer wall of the air guiding pipe 15 is fixedly connected to a filter housing 17. The outer wall of the filter housing 17 is fixedly connected to the outer wall of the fixing frame 27. The inner wall of the filter housing 17 is fixedly connected to a second motor 18.

A filter screen 22 is arranged on the inner wall of the connecting pipe 21. The outer wall of the connecting pipe 21 is fixedly connected to a fan 23. The outer wall of the fan 23 is fixedly connected to an exhaust pipe 24. The lower surface of the filter housing 17 is fixedly connected to a sinking pipe 25. A dust collecting bucket 26 is arranged on the lower surface of the sinking pipe 25. The aluminum ingot furnace 28 is arranged on the outer wall of the base 1.

[0025] Specifically, the flue gas is pumped by the fan 23, converges through the air collecting hood 12, and then enters the filter cartridge 16 through the telescopic pipe 13 and the air guiding pipe 15. The filter cartridge 16 filters the dust. Then, the second motor 18 is started to drive the scraper 20 to scrape on the inner wall of the filter cartridge 16 through the connecting rod 19 to prevent the filter cartridge 16 from being blocked. The dust enters the dust collecting bucket 26 through the sinking pipe 25. The filtered air is filtered again by the filter screen 22 in the connecting pipe 21 and then discharged from the exhaust pipe 24.

[0026] Working principle: When using this device, raw materials are put into the aluminum ingot melting furnace 28 for melting. The first motor 2 is started to drive the first bevel gear 3 at the output end to rotate. The first bevel gear 3 and the second bevel gear 4 mesh and rotate to drive the transmission shaft 5 to rotate. The transmission shaft 5 drives the transmission gear 7 to rotate. The transmission gear 7 drives the rack 8 to slide up and down. The rack 8 drives the first sleeve 11 to lift and lower through the bracket 10. The telescopic tube 13 at the upper part of the first sleeve 11 can be telescopic and a gas collection hood 12 is fixed at the lower part. Thus, the gas collection hood 12 can be lifted and lowered to adjust its distance from the aluminum ingot melting furnace 28. The fan 23 is started to suck the fumes through the air duct 15 into the filter cartridge 16. Then the second motor 18 is started to drive the connecting rod 19 at the output end to rotate. The connecting rod 19 rotates to drive the scraper 20 to slide on the inner wall of the filter cartridge 16, so that the dust falls into the dust collection bucket 26 through the settling tube 25. The filtered air is discharged from the exhaust pipe 24 through the filter screen 22 in the connecting pipe 21 and the fan 23. This device can not only control the distance between the gas collection hood 12 and the aluminum ingot melting furnace 28 by adjusting the lifting of the gas collection hood 12, but also filter and collect the waste gas and dust during melting.
