Description

Automatic dust collecting device for aluminum pouring of mixing furnace

Technical Field

The utility model belongs to the technical field of aluminium electroloysis production, concretely relates to mixing furnace falls aluminium automatic dust arrester installation.

Background

In the aluminum electrolysis production process, aluminum liquid produced by an electrolytic cell every day needs to be pumped out by a vacuum ladle and transferred to a casting workshop, and is poured into a casting workshop mixing furnace, and then related products such as aluminum ingots, aluminum plates and the like can be produced after a plurality of procedures such as material preparation, slag skimming, standing and the like. At present, three ways of pouring molten aluminum into a mixing furnace through vacuum ladle are available: one method is characterized in that molten aluminum in a vacuum ladle is pumped into a mixing furnace through a siphon, smoke dust is not generated in the method, certain compressed air power energy consumption is consumed, the time consumption is long, the method is not suitable for a high-capacity aluminum plant, and only a few aluminum plants with low capacity adopt the method at present; the second method is that the vacuum ladle is directly poured into a chute of the mixing furnace and flows into the mixing furnace through the chute, the method needs to be manually determined as the vacuum ladle, has larger safety risk and is gradually eliminated at present; the third method is to dump the molten aluminum by a ladle tilting device, namely, the vacuum ladle is hung on the tilting device, and the molten aluminum in the vacuum ladle is dumped into a chute of the mixing furnace and flows into the mixing furnace by the rotation of the tilting device, which is the mainstream adopted at present. Whether the manual work is directly emptyd or the ladle tipping device is adopted for emptying, a large amount of smoke dust can be generated in the process of emptying, the environment of a production field is worsened, the normal operation of surrounding equipment is influenced, and the occupational health of field workers is also influenced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a mixing furnace automatic dust arrester installation of falling aluminium to above-mentioned problem.

In order to achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides a mixing furnace automatic dust arrester installation of falling aluminium, includes the gas collecting channel, the gas collecting channel is located the top of falling aluminium chute, the gas collecting channel is connected with mixing furnace dust removal total smoke pipe through flue branch pipe.

Furthermore, the flue branch pipe between the gas collecting hood and the main dedusting smoke pipe of the mixing furnace is arranged in a straight line of the shortest line, so that the influence on the dedusting of the main dedusting smoke pipe of the mixing furnace when the flue branch pipe is too long and the dust collection of the flue branch pipe is opened is avoided.

And furthermore, a support frame is arranged outside the gas collecting hood and the flue branch pipe and used for reinforcing the gas collecting hood and the flue branch pipe.

Furthermore, a valve is arranged on the flue branch pipe and used for controlling the start and stop of dust collection of the gas collecting hood.

Further, the valve is an electrically controlled valve.

Furthermore, the valve is connected with the ladle tipping control system and forms interlocking with the lifting action of the ladle tipping device.

Furthermore, the automatic control system also comprises a time relay, wherein the time relay is connected in the two-man ladle tipping control system and is used for realizing the delayed closing of the valve.

Compared with the prior art, the utility model has the advantages of it is following:

the gas collecting hood is arranged above the aluminum pouring chute and is connected with the dust removing main smoke tube of the mixing furnace through the flue branch tube, so that the dust removing system of the mixing furnace is fully utilized to absorb smoke dust generated in the process of pouring aluminum liquid in a vacuum ladle, the environmental pollution of a production site is avoided, and the environment of site operation is improved; meanwhile, the valve and the ladle tilting device are lifted to form interlocking, so that the valve is automatically opened and closed in the process of pouring molten aluminum in the vacuum ladle; the utility model discloses operation safe and reliable, the site environment improves the effect and is showing, has fine spreading value and using value.
