Description
Technical field
The utility model belongs to the STEELMAKING PRODUCTION equipment technical field of metallurgy industry, more particularly to a kind of rotary oxygen rifle is scraped
Slag device.
Background technology
Oxygen rifle is one of key equipment of pneumatic steelmaking, and the bath lancing and blowing when it is responsible for blowing into converter are tied
In Shu Houxiang converters nitrogen flushing to carry out slag splashing to protect the task of furnace lining.Oxygen rifle can not during blowing and slag splashing
Slag can be adhered on oxygen rifle outer layer pipe with avoiding, if not in time struck off slag, with the increase for smelting number of times, oxygen rifle
The slag adhered on outer layer pipe is more and more thick, when serious oxygen rifle can be made not lift normally, if imperative operation will burn oxygen
Rifle lifting motor breaks steel wire rope, at this moment can only cut off the oxygen rifle of dry slag with flame cutting machine, removes what is cut off
Oxygen rifle, more renews oxygen rifle.Therefore cause the service life of oxygen rifle to be greatly lowered, not only add the cost depletions of oxygen rifle, and
Frequent burning torch, the continuity that rifle destroys STEELMAKING PRODUCTION is changed, add the labor intensity of workman.
At present, oxygen rifle slag manner of cleaning up has two kinds of manual cleaning and automatic scraping slag：1) cleared up using manual cleaning mode
During the slag adhered in oxygen rifle, not only working environment is severe, and labor intensity is big, and can only could be carried out when stopping production,
It is time-consuming, inefficiency；2) existing automatic scraping slag equipment, it is substantially consistent that it, which scrapes slag principle, is all when converter is blown
While refining or slag splashing finish oxygen rifle proposition oxygen rifle mouthful, two machineries in air control unit driving left and right of Dreg Scraping Device of Oxygen Lance
Arm, makes the U-shaped or semi-circular slag scraper cutter head of mechanical arm close up the oxygen rifle for holding around adhesion slag, when oxygen rifle is lifted, slag scraper knife
Head beginning scraping adheres to the slag in oxygen rifle.But the complexity of oxygen lance operation necessarily causes slag in oxygen rifle mixed viscous, sometimes
One layer of slag of even one layer steel, runs into such a situation, existing Dreg Scraping Device of Oxygen Lance is difficult to the slag for wiping oxygen rifle adhesion off, if nothing
Method effectively removes slag, is easy to cause security incident, therefore have potential safety hazard.

Embodiment
Firstly, it is necessary to which explanation, the rotary oxygen rifle of the utility model will be illustrated by way of example and scrapes slag below
Concrete structure, feature and advantage of device etc., but all descriptions are intended merely to what is illustrated, and should not be construed as pair
The utility model forms any limitation.In addition, any single skill for being described by or implying in the mentioned each embodiments of this paper
Art feature, or shown or implicit any single technical characteristic in the drawings, still can these technical characteristics (or its
Equivalent) between proceed to be combined or delete, may be without this practicality that directly refer to herein newly so as to obtain
More other embodiments of type.
Incorporated by reference to referring to figs. 1 to Fig. 7, below the embodiment that is just provided by this come to the rotary oxygen rifle of the utility model
Slag scraper is illustrative.
The left and right grade noun of locality involved by the utility model is defined on the basis of accompanying drawing of the present utility model, should
Work as understanding, the use of the noun of locality is not intended to limit the claimed scope of the application.
As shown in figures 1-4, rotary Dreg Scraping Device of Oxygen Lance of the present utility model, including base 1a, 1b, cylinder 2a, 2b are scraped
Slag arm 3a, 3b, proximity switch 6a, 6b, proximity switch support 7a, 7b, and atmospheric control (not marked in figure)；
From figure 1 it appears that the rotary Dreg Scraping Device of Oxygen Lance of the utility model is bilateral symmetry, 2a, 2b one end point
It is not hinged with base 1a, 1b, the other end is hinged with scraping slag arm 3a, 3b respectively, scrapes slag arm 3a, 3b respectively by a hinge
On base 1a, 1b.
Each slag arm of scraping includes a pivoted arm, a ring scraper 5 and two scrapers 4 in the utility model.
In addition, in the utility model cylinder can also using hydraulic cylinder or other can realize similar motion part carry out
Replace；Atmospheric control can also be replaced using hydraulic control system or other corresponding control systems.
While slag is scraped, in order to preferably collect slag, (do not marked in figure provided with a ring baffle scraping slag arm bottom
Note).
After oxygen rifle finishing blowing, oxygen rifle rises, and the rotary Dreg Scraping Device of Oxygen Lance of the utility model enters working condition, the rotation
Rotatable Dreg Scraping Device of Oxygen Lance is that described atmospheric control control cylinder 2a, 2b are promoted respectively to be scraped when starting that oxygen rifle 8 is carried out scraping slag
The bearing pin that slag arm 3a, 3b is connected to around it on two symmetrically arranged bases is rotated, and scrapes slag arm 3a, 3b move toward one another, and this practicality is new
Proximity switch support 7a, 7b are separately installed with base 1a, 1b of type, proximity switch support 7a, 7b are separately installed with close open
Close 6a, 6b and cylinder 2a, 2b position is respectively induced as inductor, when oxygen rifle is just closed up and enclosed by scrape slag arm 3a, 3b of both sides
When embracing, cylinder 2a, 2b stop motion, the rotary Dreg Scraping Device of Oxygen Lance of the utility model starts to scrape slag work.
Scraper 4 and ring scraper 5 are bolted on respectively to be scraped on slag arm, each scrapes and two scrapers and one are housed on slag arm
Individual ring scraper, when scraping slag, first passing through the left and right sides, totally four scrapers shred the slag sticked in oxygen rifle, then pass through the left and right sides
Residue in oxygen rifle is rejected clean by two ring scrapers.
Due to setting four scrapers so that the slag sticked on oxygen rifle outer wall has multiple stress points, so contributes to brokenly
Broken slag, makes slag be come off from oxygen rifle outer wall.
Scrape after the completion of slag work, described atmospheric control control cylinder 2a, 2b are promoted respectively scrapes slag arm 3a, 3b around its company
The bearing pin being connected on two symmetrically arranged bases is rotated, and is scraped slag arm 3a, 3b and is moved opposite to each other, holds it away from the scraper group of both sides
State.
The rotary Dreg Scraping Device of Oxygen Lance of the utility model is relative to Dreg Scraping Device of Oxygen Lance of the prior art, due to setting multiple scrape
Slag knife, makes the slag on oxygen rifle outer wall have multiple stress points, more contributes to broken slag, scrapes slag effect and be improved.
Certainly the number for each scraping the scraper on slag pivoted arm is not limited to two, but at least two, and the number of scraper is more,
The stress point of the slag of oxygen rifle outer wall is more, strikes off that slag is easier, but because the number of scraper is more, for the investment of equipment
Or cost is higher, so in actual production process, should be according to the actual number for asking condition to set scraper.
Only elaborate rotary Dreg Scraping Device of Oxygen Lance of the present utility model by way of example above, this few example is only for saying
Bright principle of the present utility model and embodiments thereof are used, rather than to limitation of the present utility model, are not departing from the utility model
Spirit and scope in the case of, those skilled in the art can also make various modifications and improvement.Therefore, all equivalent skills
Art scheme all should belong to category of the present utility model and be limited by every claim of the present utility model.
