Abstract
The utility model provides a door-type moveable dust hood which comprises a bag-type dust collector with an air suction device, a fixed smoke tube and a hood body and is characterized in that the dust hood also comprises a door-type travelling crane; the hood is fixed on a transmission beam of the travelling trolley and above an electric arc furnace, and the hood is connected with the fixed smoke tube through a moveable smoke tube. The utility model has the advantages that the smoke exhausted by the electric arc furnace can be effectively collected, the dedusting efficiency is high and can reach 98 percent or more, and the smoke exhaustion reaches or is superior to nationally regulated smoke exhaustion standards.
Description
Technical field: the utility model relates to a kind of clarifying smoke dust exhaust apparatus that uses in vanadium iron electric arc furnaces and other electric arc furnaces, particularly a kind of the portable dust shield of type.
Background technology: in existing vanadium iron smelting industry, the employed clarifying smoke dust exhaust apparatus of its vanadium iron electric arc furnaces is a dry dust removal equipment, and generally by sack cleaner, fixedly smoke pipe, cover body constitute, it is motionless that cover body is fixed a place.The deficiency that this dry dust removal equipment in use exists has: the flue dust to the electric arc furnaces discharging can not effectively be collected, and efficiency of dust collection is not high, does not reach the dust emission standard of national regulation.Because smelt in the actual production process at vanadium iron, electric arc furnaces will experience charging, smelt, deslagging, go out processes such as finished product, the position of electric arc furnaces is not changeless, can often do pendular movement, along with electric arc furnaces is done pendular movement, the space of its soot emissions also changes thereupon, but fixed cover body can only have preferable collecting effect to the flue dust of electric arc furnaces a certain position discharging, after the electric arc furnaces position changes, can not corresponding variation take place with the electric arc furnaces change in location then, the flue dust that electric arc furnaces is given off after because of change in location then can not effectively be collected like this, influences dust removing effects.
Summary of the invention: the purpose of this utility model is at the not good problem of existing smoke medicining dust-removing effect in the existing vanadium iron smelting arc furnace, and provides a kind of cover body that the high portable dust shield of smoke and dust purifier-door type of efficiency of dust collection of respective change can take place with the electric arc furnaces change in location.
Can realize the purpose of this utility model by following technical proposals, a kind of the portable dust shield of type, comprise: be provided with the sack cleaner of air intake device, fixedly smoke pipe, cover body, it is characterized in that, also comprise a type driving, cover body is fixed on the transmission beam of driving, is positioned at the top of electric arc furnaces, and cover body connects with fixing smoke pipe by movable smoke pipe.
Movable smoke pipe is with fixedly connecting for inserting of smoke pipe connects.
Stablize for cover body smoke pipe in parallel move is connected, the length that movable smoke pipe is inserted in the fixing smoke pipe is 400-1900mm.
The driving of door type is height road wheel structure.
Effect of the present utility model is: it can effectively be collected the flue dust of electric arc furnaces discharging; the efficiency of dust collection height; can reach (efficiency of dust collection of existing apparatus can only reach about 85%) more than 98%; reach and be better than the dust emission standard of national regulation, for the protection of operating personnel's healthy and environment provides strong assurance.This mainly is, on existing dust arrester, increased by a driving, cover body is fixed on the transmission beam of driving, be positioned at the top of electric arc furnaces, when electric arc furnaces was done pendular movement, the vertical plane line that cover body is done pendular movement at the drive lower edge electric arc furnaces of driving was done horizontal movement, like this, cover body can be positioned at all the time electric arc furnaces smoke evacuation space directly over, the flue dust of electric arc furnaces discharging is effectively collected.
Below in conjunction with embodiment and accompanying drawing the utility model is further set forth:
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment:
Referring to accompanying drawing 1, door type driving 1 is made of driving transmission beam 11, entablature 12, high rail 13 and high rail travelling wheel 14, sill 15, low rail 16 and low rail travelling wheel 17 and transmission device 18, is height road wheel structure.Cover body 2 is fixed on the transmission beam 11 of type driving 1.Cover body 2 is positioned at the top of electric arc furnaces 3, and cover body 2 connects with fixing smoke pipe 5 by movable smoke pipe 4.Fixedly smoke pipe 5 connects with the sack cleaner 6 that is provided with air intake device.Movable smoke pipe 4 is with fixedly connecting for inserting of smoke pipe 5 connects.Stablize for cover body 2 smoke pipe in parallel move is connected, the length that movable smoke pipe 4 is inserted in the fixing smoke pipe 5 is 400-1900mm.Electric arc furnaces 3 activities are fixed on the rack beams 7, can swing along vertical plane.During work, during electric arc furnaces 3 change in location, start transmission device 18, transmission device 18 drives driving transmission beam 11 and moves forward and backward, and driving transmission beam 11 drives cover body 2 and moves forward and backward along electric arc furnaces 3 axial plane levels.Flue gas moves upward along dust hood 2 bottoms, draws in cover body 2, concentrates by movable smoke pipe 4 and discharges cover bodies 2, is drawn onto processing in the sack cleaner 6 by fixing smoke pipe 5.
Claims (4)
1, the portable dust shield of a kind of type comprises: be provided with the sack cleaner of air intake device, fixedly smoke pipe, cover body, it is characterized in that, also comprise a type driving, cover body is fixed on the transmission beam of driving, is positioned at the top of electric arc furnaces, and cover body connects with fixing smoke pipe by movable smoke pipe.
By the portable dust shield of described type of claim 1, it is characterized in that 2, movable smoke pipe is with fixedly connecting for inserting of smoke pipe connects.
By the portable dust shield of described type of claim 2, it is characterized in that 3, the length that movable smoke pipe is inserted in the fixing smoke pipe is 400-1900mm.
4, by claim 1 or 2 or the portable dust shields of 3 described types, it is characterized in that the driving of door type is height road wheel structure.
