The dust removal component includes a plurality of first screens and second screens. The plurality of first screens and second screens are evenly and alternately arranged at intervals along the extension direction of the smoke exhaust pipe. A blower is arranged on one side of the smoke exhaust pipe close to the electric furnace body. The air suction end of the blower is connected to the smoke collecting hood, and the air outlet end of the blower is connected to the air inlet end of the smoke exhaust pipe. A smoke suction component is arranged at the air outlet end of the smoke exhaust pipe. The smoke suction component includes a water tank and a first air outlet pipe. The air outlet end of the smoke exhaust pipe extends into the water tank and is communicated with the air inlet end of the first air outlet pipe. The air outlet end of the first air outlet pipe extends to the bottom of the water tank. A second air outlet pipe is arranged on the top of the water tank. The flue gas enters the first air outlet pipe through the smoke exhaust pipe and is discharged from the water tank through the second air outlet pipe.

[0007] During the operation of the electric furnace, the flue gas generated is sucked out by the blower and enters the dust removal component through the smoke exhaust pipe. The first screen and the second screen filter and remove dust from the flue gas. The dust-removed flue gas enters the water tank through the first air outlet pipe for smoke suction and further dust removal. The gas after dust removal and smoke suction is discharged from the water tank through the second air outlet pipe, improving the safety of the electric furnace.

[0008] Optionally, the first screen and the second screen are arranged in a sleeve, and the outer periphery of the sleeve abuts against the inner wall of the smoke exhaust pipe.

[0009] The first screen and the second screen are connected to the smoke exhaust pipe through a sleeve, which facilitates the staff to clean the first screen and the second screen, and improves the dust removal efficiency of the dust removal component.

[0010] Optionally, the smoke exhaust pipe is horizontally extended and arranged at the top of the smoke collecting hood. The bottom of the first screen is connected to the sleeve, and there is a gap between the top of the first screen and the sleeve. The top of the second screen is connected to the sleeve, and there is a gap between the bottom of the second screen and the sleeve.

[0011] There are gaps between the top and bottom of the first screen and the second screen and the sleeve respectively, which reduces the phenomenon that the smoke flow is affected due to the blockage of the first screen and the second screen, and improves the dust removal efficiency of the dust removal component and the safety of the electric furnace.

[0012] Optionally, the outer wall of the sleeve is slidably connected to the inner wall of the smoke exhaust pipe.

[0013] Optionally, a groove is arranged on the outer wall of the sleeve along the length direction of the sleeve, and a convex block adapted to the groove is arranged on the inner wall of the smoke exhaust pipe along the length direction of the smoke exhaust pipe. The outer wall of the convex block abuts against the groove wall of the groove.

[0014] Optionally, the electric furnace body is hermetically connected to the fan, the fan is hermetically connected to the smoke exhaust pipe, the smoke exhaust pipe is hermetically connected to the first air outlet pipe, and the first air outlet pipe and the second air outlet pipe are hermetically connected to the water tank.

[0015] The beneficial effects of the present utility model are as follows: During the operation of the electric furnace, the smoke generated is sucked out by the fan and enters the dust removal component through the smoke exhaust pipe. The first screen and the second screen filter and remove dust from the smoke. The dust-removed smoke enters the water tank through the first air outlet pipe for smoke absorption and further dust removal. The gas after dust removal and smoke absorption is discharged from the water tank through the second air outlet pipe, which improves the safety of the electric furnace.
