Problems solved by technology
However, the higher the dust removal hood, the weaker the dust removal ability. If the air volume of the fan is increased, the micro positive pressure in the furnace will be destroyed, which is not conducive to the slagging of the LF refining furnace.

Embodiment Construction
[0022] The invention provides a dust removal fume hood device, which not only has a good dust removal effect, but also does not interfere with the movement of electrodes, and at the same time does not damage the micro positive pressure in the furnace.
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
[0024] Please refer to Figure 1-Figure 3 , In a specific embodiment of the present invention, the dust removal hood device includes a dust removal hood 1 . The dust removal hood 1 can communic...

The invention discloses a dust removal smoke hood device. The dust removal smoke hood device comprises a dust removal smoke hood; the dust removal smoke hood can communicate with a dust removal main pipe; an avoiding port is formed in the side wall of the dust removal smoke hood for enabling objects below the dust removal smoke hood to pass through; and a dust removal stop chain is suspended in the avoiding port. The avoiding port is formed in the side wall of the dust removal smoke hood for enabling electrodes below the dust removal smoke hood to pass through, so that the position of the dustremoval smoke hood can be arranged to be lower; and the lower of the position of the dust removal smoke hood is, the more prominent of the dust removal effect is. In order to prevent smoke from overflowing from the avoiding port, the dust removal stop chain can be suspended in the avoiding port; and not only an effect of closing the avoiding port can be achieved by the dust removal stop chain, but also movement of the electrodes is stopped. In addition, the air volume of a fan of the dust removal smoke hood device is not changed, so that micro positive pressure in a furnace is not destructed,and slagging of an LF refining furnace is facilitated. The dust removal smoke hood can be set as a mobile form for cooperating double-station operation of the electrodes.
Description
technical field [0001] The invention relates to the field of LF refining furnaces, in particular to a dust removal fume hood device. Background technique [0002] LF refining furnace (ladle refining furnace) has a double-station three-arm rotating electrode. The electrode works alternately between the two stations. The LF refining furnace will generate a lot of smoke and dust during the working process, and the smoke and dust will overflow from the furnace cover. In order to remove dust, a dust removal hood can be placed above the LF refining furnace. The dust removal hood is connected to the main dust removal pipeline. Under the action of the fan, the smoke will enter the main dust removal pipeline through the dust removal hood. The electrode is first raised before moving from the first station to the second station, and then moved to the second station. In order to prevent the side wall of the dust removal hood from interfering with the electrodes, the position of the d...
