Description
Technical field
The utility model relates to the device field of removing incrustation for smelting furnace, is specially a kind of anti-lock Dreg Scraping Device of Oxygen Lance.
Background technology
The oxygen rifle is when steel-making the high pressure high-purity oxygen to be blown into metal pool top in the stove at a high speed, and with the tubular equipment of high pressure water cooling protection system, is the visual plant of top-blown oxygen steelmaking.After the blowing of oxygen rifle, oxygen rifle rifle head and head thereof have slag at a segment limit and adhere to, and slag is formed skull in oxygen rifle lifting process, and these skulls such as untimely cleaning can add up too much can affect the normal use of oxygen rifle.At present the normal operation Dreg Scraping Device of Oxygen Lance imposes a constant dreg scraping force to root out slag to skull.Slag is because of slagging scorification type and slagging scorification mode difference, and also different with the adhesive power of oxygen rifle rifle head, needed dreg scraping force is different when therefore removing.When existing dregs scraper was implemented to scrape slag after closure, dreg scraping force can't be regulated, and was difficult to slagging-off if dreg scraping force is too small, and the excessive then easily locking of dreg scraping force causes the hoisting system overload, damaged motor even caused and break wireline and lead to a disaster.
The utility model content
In order to overcome the defective of prior art, provide that a kind of efficient that removes slag is high, scarfing cinder thoroughly, applied widely, safe and reliable slag cleaning device, the utility model discloses a kind of anti-lock Dreg Scraping Device of Oxygen Lance.
The utility model reaches goal of the invention by following technical solution:
A kind of anti-lock Dreg Scraping Device of Oxygen Lance, comprise and scrape the slag unit, scrape the slag unit and comprise dreg scraping head, dreg scraping head is fixed on the base plate by a dicephalous scraper of tool and consists of, it is characterized in that: scrape the slag unit and also comprise base, bearing, scrape the slag arm, cylinder and spring assembly, bearing is fixed on an end of base bottom, scrape an end of slag arm for rotating end, the other end of scraping the slag arm is the working end, the rotation end of scraping the slag arm is connected with bearing, and the cylinder body of cylinder is hinged on the top of base, and the telescopic end of cylinder piston rod is connected an end and is connected with spring assembly, the other end of spring assembly connects with the working end of being connected the slag arm, and the base plate of dreg scraping head is fixed on the working end of scraping the slag arm.
Described anti-lock Dreg Scraping Device of Oxygen Lance is characterized in that: the quantity of scraping the slag unit is at least two, and each scrapes the relative and centrosymmetry distribution with dreg scraping head of slag unit.
When the utility model uses, the piston rod of cylinder promotes to scrape the slag arm around this bearing rotary, and dreg scraping head is pressed on the oxygen gun body, and the scraper of dreg scraping head breaks slag under pressure, along with the lifting of oxygen gun body, slag is continued breaks and comes off from oxygen gun body under action of gravity.If run into adhesion the jail obstinate slag, the scraper of dreg scraping head can not break slag, connects cylinder and plays shock absorption with the spring assembly of scraping the slag arm, the compression of spring assembly pressurized, continued to remove operation so that dreg scraping head is skipped adhesion place of obstinate slag, avoided the damage of dreg scraping head and slag scraper.
The utlity model has following characteristics:
1. the length of spring assembly can be regulated within the specific limits, thereby realizes the adjusting to oxygen gun body dreg scraping force size, to adapt to the various slag situations of scraping;
2. spring assembly has shock absorption, when running into the slag that can't strike off, can automatically skip and prevents locking, avoids equipment breakdown shape machine or destroys the hoisting system;
3. after the blade wears, thereby can make scraper apply the larger power of abolishing to slag by the elastic force that increases spring assembly, make the dreg scraping force of scraper remain certain value, kept scraping the stability of slag operation, avoid reducing or scraping reducing of slag thickness of dreg scraping force, prolonged the work-ing life of scraper.
The beneficial effects of the utility model are: simple in structure, easy to operate, and long service life, applied widely, safe and reliable.

Embodiment
Below further specify the utility model by specific embodiment.
Embodiment 1
A kind of anti-lock Dreg Scraping Device of Oxygen Lance, comprise and scrape slag unit 1, scrape slag unit 1 and comprise dreg scraping head 11, base 12, bearing 13, scrape slag arm 14, cylinder 15 and spring assembly 16, as depicted in figs. 1 and 2, concrete structure is: dreg scraping head 11 is fixed on the base plate by a dicephalous scraper of tool and consists of, bearing 13 is fixed on an end of base 12 bottoms, scrape an end of slag arm 14 for rotating end, the other end of scraping slag arm 14 is the working end, the rotation end of scraping slag arm 14 is connected connection with bearing, the cylinder body of cylinder 15 is hinged on the top of base 12, the end that the telescopic end of cylinder 15 piston rods is connected with spring assembly connects, the other end of spring assembly 16 connects with the working end of being connected slag arm 14, and the base plate of dreg scraping head 11 is fixed on the working end of scraping slag arm 14.Scrape slag arm 14 and be rocker arm body, cylinder 15 provides closed power, is provided with the adjustment structure that compression spring consists of dreg scraping force in the spring assembly 16.
In the present embodiment, the quantity of scraping slag unit 1 is two, scrapes slag unit 1 with dreg scraping head 11 relative and centrosymmetry distributions for two.
When the utility model uses, as shown in Figure 2, scrape slag unit 1 with two and be centered around oxygen gun body 2 external symmetrys layout, the piston rod of cylinder 15 promotes to scrape slag arm 14 around these bearing 13 rotations, dreg scraping head 11 is pressed on the oxygen gun body 2, the scraper of dreg scraping head 11 breaks slag under pressure, along with the lifting of oxygen gun body 2, slag is continued breaks and come off from oxygen gun body 2 under action of gravity.If run into adhesion the jail obstinate slag, the scraper of dreg scraping head 11 can not break slag, 16 shock absorptions of spring assembly that connect cylinder 15 and scrape slag arm 14, the compression of spring assembly 16 pressurizeds, continued to remove operation so that dreg scraping head 11 is skipped adhesion place of obstinate slag, avoided the damage of dreg scraping head 11 and slag scraper.
