Abstract
The utility model relates to a top absorbing cover for catching soot at blast furnace taphole, which consists of a moving mechanism and a catching cover 3, wherein, the moving mechanism consists of a vertical shaft 1 and a rotating arm 2; the vertical 1 is fixed with a sleeve rotating around the vertical shaft 1, and one end of the rotating arm 2 is fixedly connected with the sleeve, and the other end is fixedly connected with the catching cover 3; two sides at the lower part of the catching cover 3 are provided with lateral guard sheets 6, and the guard sheets 6 are connected with the catching cover 3 through a pulley 4 and a slideway 5. With simple structure and reliable movement, the utility model enhances catching effect, solves the problems of high-temperature radiation and molten iron splash, improves labor environment of workers and the security.
Description
Technical field
The utility model belongs to the ventilating dust-removing technology field, is specifically related to a kind of blast furnace iron notch that is used for and captures the top suction cover that flue dust is used.
Background technology
It is a kind of dirt source catching apparatus that cover is inhaled on the blast furnace iron notch top, uses very extensive at blast furnace iron notch.The enclosed hood of relative other types, the advantage that cover is inhaled on the top is: efficiency of seizing dust height, a large amount of paroxysmal flue dust that produce in the time of particularly effectively capturing out stifled iron notch.Cover is inhaled on the top, can be divided into multiple pattern by different set-up modes, as uphang cover, low outstanding cover etc. of the type that moves horizontally.The top is inhaled the cover move mode and is all moved horizontally, and its common shortcoming is that volume is big, travel mechanism's complexity; the cost height moves difficulty, influences the tapping hole maintenance; simultaneously in the process of tapping a blast furnace, owing to there is not the protection of sow, molten iron splashes and radiation has constituted very big threat to operator's safety.
Summary of the invention
Inhale cover travel mechanism bulky complex for overcoming existing top; the shortcoming of no radiation proof protection, the utility model provide a kind of rotation protection top to inhale cover, to make things convenient for blast furnace maintenance; reduce cost and insecurity that cover is inhaled on the top, be subjected to the danger of hyperthermia radiation and scald when avoiding direct labor's ordinary production.
Technical solution of the present utility model is:
Cover is inhaled on a kind of rotation protection top, is used for the capture of iron-smelter blast furnace iron notch flue dust, and travel mechanism is made of vertical pivot and turning arm, vertical pivot is fixed on the blast furnace table, be fixed with the sleeve around its rotation on the vertical pivot, turning arm one end is fixedlyed connected with sleeve, and the other end is fixedlyed connected with fume trap cover.In both sides, fume trap cover bottom side guard plate is set, side guard plate is connected by the pulley slideway with fume trap cover.
Travel mechanism is installed on the blast furnace table, and fixing, the rotation that mainly realizes fume trap cover such as moves at action; Fume trap cover is installed on the turning arm, mainly realizes the capture of flue gas; Pulley, slideway, side guard plate all are fixed on the fume trap cover, mainly are the effects that realizes protection and stop flue gas, and side guard plate is by sliding conveniently to open the operation of taphole stopping machine simultaneously.
The Wind Coverage Calculation that cover is inhaled on the top of blast furnace iron notch generally is to uphang the cover computing method with thermal process also to determine in conjunction with the test analogy method.
During normally tapping a blast furnace, fume trap cover is fixed on the tapping hole top by turning arm rotation, at this moment, is communicated with the system exhaust column above the fume trap cover.Remove protective plate, the iron notch drill action is beaten tapping outlet and is tapped a blast furnace.Remove when normally tapping a blast furnace when iron notch drill, side guard plate is moved on to the tapping hole both sides, play protection and stop the effect of flue gas.Side guard plate and top confined space of fume trap cover formation, make the sow top basically form a closed space, can store, block flue gas and the molten iron that spatters outward, also can reduce that crossflow has increased the effect of gathering dust to the interference of iron port area flow of flue gas in the cast house.During tapping a blast furnace, the workman according to the observation and disclose the needs of ditch, can arbitrarily mobile at any time side guard plate to any position, very convenient.
When a stove molten iron has gone out, remove side guard plate, taphole stopping machine action, envelope stifled iron notch.
When cast house overhauls, fume trap cover is left tapping hole by the turning arm rotation, and temporary fixed, so that maintenance.
Rotation protection top suction cover is mainly fixed by vertical pivot and turning arm, and vertical pivot maintains static, and during operation, hydraulic motor or other motor drive mechanism driven wheel driven rotary sleeves rotate, thereby realizes the rotation of top suction cover.
The beneficial effect of the utility model tool is:
1. cover is inhaled on the rotation protection that the utility model proposes top, and simple in structure, steel consumption is little, and is easy to make, moves reliably, has strengthened the capture effect simultaneously, has solved hyperthermia radiation and the molten iron problem of hurting sb.'s feelings of splashing.
2. cover is inhaled on the rotation protection top that the utility model proposes, and by rotation, has simplified travel mechanism, has saved to take up room; By mobile protective plate, improve direct labor's work situation greatly, improved security.

The specific embodiment
Cover is inhaled on the rotation protection top that the applicant has implemented the utility model proposes in Shoudu Iron and Steel Co iron-smelter 3# blast furnace discharge yard dedust innovation engineering, and it is good that the cover operation conditions is inhaled on rotation protection top.
The high furnace parameters of 3#:
● blast furnace 2650m
3, totally 3 of cast houses, 2 cast houses tap a blast furnace in turn, 1 cast house maintenance
● dust pelletizing system is handled air quantity: 650000m
3/ h
● former deduster pattern: atmosphere blowback cloth bag 10000m
2Two
Do not have the top before transforming and inhale cover, the paroxysmal flue dust is very big when opening stifled iron notch, and the post dust concentration exceeds standard, and the user determines to transform, and adopts the rotation protection top that the utility model proposes to inhale cover, and concrete implementation step is as follows:
1, travel mechanism utilizes former cast house to hang and covers the machine transformation, and travel mechanism is made of vertical pivot 1 and turning arm 2, is fixed with the sleeve around its rotation on the vertical pivot 1, and turning arm 2 one ends are fixedlyed connected with sleeve, and the other end is fixedlyed connected with fume trap cover 3;
2, fume trap cover 3 is fixed on and hangs on the machine of lid;
3, in both sides, fume trap cover 3 bottom side guard plate 6 is set, side guard plate 6 and fume trap cover 3 pass through pulley
4, slideway 5 connects.
After above installment work is finished, do experiment at the scene, according to result of the test, post, stokehold dust concentration＜10mg/Nm
3, the smoke catching effect is very desirable, and production maintenance is also very convenient simultaneously, obtains user's favorable comment deeply.
