Description
Technical field
The utility model relates to a kind of blast furnace throat fouling cleaning tools, belong to blast furnace in metallurgical industry furnace throat fouling cleaning and set
Standby technical field.
Background technique
Currently, each steel enterprise is influenced by market overall situation, production cost how is reduced, already pursuing as each enterprise
Primary goal.To reduce sinter production cost, in the ingredient of sinter, generally all with addition of blast furnace dedusting ash.With increasing
Blast furnace alkali metal load is sharply increased in furnace dedusting ash, causes alkali metal circulation collection inside blast furnace, easily leads to and ties at furnace throat
Dirt.Once occur the case where fouling at furnace throat, influences very big on being uniformly distributed for furnace roof air-flow, the direct motion of blast furnace will be by broken
It is bad, and the fouling at furnace throat position is difficult with conventional prepurging method processing.
Currently, there are mainly two types of the methods of processing blast furnace throat fouling: first is that using damping down establishment officer in furnace roof manhole
Place, with oxygen to fouling position burn off.This method processing progress is slow, takes a long time, it is also necessary to a large amount of oxygen
Pipe increases production cost.It is burnt using oxygen, the bad control in burn off position, is easy to burn out the water cooling clinker tile damage equipment at furnace throat.
And be not thorough with what oxygen burn off fouling was handled, fouling can not be eradicated, after air-supply production, fouling position can also generate quickly,
Continue to influence the working of a furnace；Second is that taking hanging scaffold after the cool furnace of damping down, personnel, which enter, clears up fouling in furnace.Although this method can thoroughly be located
Manage fouling position, but the time that cool furnace needs is longer, production loss is larger, and personnel enter inside blast furnace risk compared with
It is high.
Utility model content
The utility model aim is to provide a kind of blast furnace throat fouling cleaning tool, can be quickly and easily by blast furnace throat
Fouling is cleaned out, and securely and reliably, solves the problems, such as background technique.
The technical solution of the utility model is:
A kind of blast furnace throat fouling cleaning tool, include slide bar, sliding hammer, mounting flange, pull ring, stop flange and drawstring,
Mounting flange and stop flange are separately fixed at the both ends of slide bar, and the slide bar between mounting flange and stop flange, which is equipped with, to be slided
Hammer, the sliding hammer are cylinder, and the center of sliding hammer is equipped with the hole matched with slide bar, and the two sides of sliding hammer are respectively equipped with a drawing
Ring, bolt has drawstring on the pull ring.
The slide bar is round bar, and sliding hammer covers on slide bar.
The pull ring of the sliding hammer two sides is arranged symmetrically.
Using the utility model, when clearing up blast furnace throat fouling, first with wirerope by the tool stop flange with
One end that the tool is equipped with mounting flange after hoist slings the tool, is inserted into blast furnace by the connection of throat platform hoist
Inside, and fixed with iron wire or wirerope, then operator pulls sliding hammer by drawstring, the impact force generated using sliding hammer
So that furnace throat fouling is fallen off, realizes quickly cleaning for blast furnace throat fouling.
The beneficial effects of the utility model are: blast furnace staying can organizer after having handled coal gas first is that not needing cool furnace
Member's cleaning substantially reduces the time required for cleaning fouling position, smaller to Influence of production；Second is that entering blast furnace without personnel
Inside, entire operational security is higher, substantially reduces the probability of personal injury；Third is that compared to the method for oxygen burn off, place
The fouling position of reason is more thorough, and there is no the danger of the cooling equipment of damage furnace throat, can also save a large amount of oxygen hose, save
Save production cost.
Detailed description of the invention
Fig. 1 is the utility model main view；
Fig. 2 is the utility model side view；
In figure: slide bar 1, sliding hammer 2, mounting flange 3, pull ring 4, stop flange 5, drawstring 6.
Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1,2, a kind of blast furnace throat fouling cleaning tool, comprising slide bar 1, sliding hammer 2, mounting flange 3, pull ring 4,
Stop flange 5 and drawstring 6, mounting flange 3 and stop flange 5 are separately fixed at the both ends of slide bar 1, mounting flange 3 and limit method
Slide bar 1 between orchid 5 is equipped with sliding hammer 2, and the sliding hammer 2 is cylinder, and the center of sliding hammer 2 is equipped with the hole matched with slide bar 1,
The two sides of sliding hammer 2 are respectively equipped with a pull ring 4, and bolt has drawstring 6 on the pull ring 4.
In the present embodiment, for slide bar 1 using the drilling rod 2-3 root of tapping outlet, pull ring 4, six-edged steel are welded in the two sides of sliding hammer 2
One, mounting flange 3 and 5 diameter of stop flange are 40cm, and drawstring 6 is the rope made of hemp, 10 meters of length.
The processing and making process of blast furnace throat fouling cleaning tool is as follows:
1, two drilling rod docking are fully welded, interface is reinforced with six-edged steel repair welding and constitutes slide bar 1；
2,3 firm welding of a upper mounting flange is covered at one end 1.5m of slide bar 1；
3, by 2 sets of sliding hammer on slide bar 1；
4, in the other end of slide bar 1 welded limiting flange 5 again, it is therefore an objective to limit the operation stroke of sliding hammer 2；
5, one rope made of hemp of each bolt on the pull ring 4 of sliding hammer 2.
The application method of blast furnace throat fouling cleaning tool is as follows:
1, the tool stop flange 5 is connect with throat platform hoist with wirerope；
2, after hoist slings tool, inside the other end insertion blast furnace of the tool, operating personnel can be according to fouling
The actual conditions at position adjust the position of the front tool, determine the impetus for needing to remove position；
3, after position is chosen, the horizontal position of the tool can be fixed with iron wire or wirerope；
4, personnel are divided into four groups, every group of 1-2 people, pull-up sliding hammer 2 needs two groups of personnel, is stood respectively in big manhole upper mounting plate
Two sides, two groups of lower section personnel are responsible for drop-down sliding hammer 2 and hit fouling position.In operation process, upper and lower four groups of personnel movement will write from memory
Contract makes sliding hammer 2 on its 1.5 meters operation stroke again, plays its maximum hitting power.If the front tool is deeply tied
Dirty internal, fouling position does not fall off still, is pulled out using hoist, again alternative impetus.It hits repeatedly, finally
So that fouling position large area is fallen off, and does not injure furnace wall and cooling equipment.
