Abstract

The utility model discloses a dreg scraper used for scraping the dreg liquid on the molten iron or the molten steel, in particular suitable for scraping the dreg of the iron mixing furnace of the steel plant. The utility model is characterized in that the inner portion of a dreg scrapping rod is cooled by water and the dreg scraping process can be conducted with a movement path. The lifting of the dreg rod adopts a rolling cylinder and a wire rope for traction and a guide rail and a rolling wheel for direction guiding. The stretching of the dreg scraping rod adopts a coiling cylinder and a wire rope for traction and a direction guide wheel, a guide groove and a guide wheel for guiding. Adopting the dreg scraper can save a great amount of dreg heat for the repeated dreg manufacture process is reduced and also the worker's physical labor intensity can be reduced, the work efficiency can be improved, the content of the hazardous element in the molten iron is reduced and also the time of steel making is shortened.

Description

Dreg scraper

The utility model is a kind of Cinder Machine that removes slag liquid on molten iron or the molten steel face, is particularly suitable for the usefulness that the steel mill mixed iron blast is skimmed.

Mixed iron blast is a kind of equipment that stores molten iron between iron-smelting furnace (blast furnace) and converter, and its purposes is to coordinate to produce the unbalanced of joint rate between back two kinds of stoves and make the molten iron homogenising.The situation that Cinder Machine is skimmed to mixed iron blast is seen Fig. 1.The molten iron of iron-smelting furnace in ladle 1 handling, pours mixed iron blast 2 into, and the capacity of mixed iron blast 2 is quite big, can hold iron water amount and reach more than 1,000 ton, when converter need be used molten iron, handle mixed iron blast 2 and turn clockwise, molten iron flows into hot-metal bottle 6 through tapping hole, transports the usefulness of converter for steel-making to.Before emitting molten iron, need to handle Cinder Machine 4(and be installed on the platform 3) skimmer in the district that skims shown in Figure 1, repeatedly back and forth skim, in case slag liquid flows in the hot-metal bottle in company with molten iron, platform 3 is loaded on the workshop pillar 5

Before this mixed iron blast is not skimmed, perhaps only adopt manual skimming,, then need prolong the steel-making time, expend the heat energy of slag making more as not skimming; As adopt manual skimming, then working condition is abominable, inefficiency.

The purpose of this utility model is: a kind of Cinder Machine that can overcome above-mentioned shortcoming is provided.

The characteristics of Cinder Machine are water flowing coolings in the skimmer; Skim and to be undertaken by the certain movement track; Cylinder and rope traction are adopted in the lifting of skimmer, guide rail and roller guiding; The flexible employing Volume tube and the rope traction of skimmer, directive wheel, gathering sill and guide wheel guiding.The structure of Cinder Machine is seen Fig. 2.Cinder Machine is formed a fixed frame by base 7, four root posts 8 and entablature 9.The running part (see figure 3) of elevating mechanism is loaded on the entablature 9, and remaining part comprises that telescoping mechanism, water cooling system and skimmer all are loaded on the movable frame 10.

1. elevating mechanism is seen Fig. 2, Fig. 3.Motor 11(is added with two brakes 12) after reduction box 13 and

gear pair

14,15 twice deceleration, drive cylinder 16 and rotate, the steel wire rope 17 on the cylinder 16 is by pulley 18 movable frame 10 rise and fall of playing.The guiding of movable frame 10 when lifting is by each eight up and down of 16 directive wheel 19() carry out along eight guide rails 20 on four root posts 8.Loading capacity when alleviating lifting is furnished with balance weight 21.

2. telescoping mechanism is seen Fig. 2, Fig. 4 and Fig. 5.Motor 22 drives Volume tube 25 through belt 23 and reduction box 24, and the two ends of steel wire rope 26 link to each other with the two ends of dolly 28 by two pulleys 27 on the Volume tube 25, and dolly 28 is used bolting with skimmer 29.When Volume tube 25 rotated, steel wire rope 26 contracted after being with dolly 28 to protract together with skimmer 29.Guiding when skimmer 29 is flexible is to be rolled in fixed gathering sill 31 and skimmer 29 slides on guide wheel 32 and carries out by two pairs of directive wheels 30 on the dolly 28.

3. the water cooling of skimmer is seen Fig. 5.Skimmer 29 is a long seamless steel pipe 33, and cooling water pipe 34 places in the pipe 33, is welded with a plurality of supports 35 outside the pipe 34 so that be supported on pipe 33 inwalls.Cooling water is entered by Fig. 5 left end water inlet pipe, and current are discharged through the discharge outlet of Fig. 6 C-C figure near taking off slag plate (also claiming deslagging head) 36 backs by pipe 34 outer returning.

4. skim and see Fig. 6 by the certain movement track.The protruding rail 37 of on skimmer 29, burn-oning from plate 36 a distance of skimming, the length of protruding rail 37 equals the stroke of skimming, and protract at skimmer 29 (being moving right of Fig. 6) is just during the skimmer idle stroke, protruding rail 37 is with pinch roller 38 jack-up of screwdown gear, and skimmer 29 levels are protracted; When contracting behind skimmer, screwdown gear is pressing protruding rail 37 to force skimmer 29 to move down under the stopping of block 39, and the plate 36 of skimming penetrates slag liquid, and deslagging head 36 is skimmed by the movement locus of Fig. 7.

The comparison of the utility model and prior art.Before this mixed iron blast is not skimmed, perhaps only adopt manual skimming.As not skimming, then need prolong the steel-making time, expend the heat energy of slag making more; As adopt manual skimming, then working condition is abominable, inefficiency.After adopting this Cinder Machine, can save a large amount of slag making heat energy, can alleviate workman's physical labor intensity, increase work efficiency, reduce the content of harmful element in the molten iron and shorten the steel-making time owing to reduce the repetition slag making.

Most preferred embodiment.Cinder Machine is used for mixed iron blast and skims.Before the work, skimmer be in extreme lower position and after condense and put; The water cooling system of skimmer must be unimpeded, and the pressure of water is (〉=2 crust) enough, just can skim, and as the hydraulic pressure deficiency, does not then allow to skim.

1. adjust the upright position (see figure 1) of skimmer.Handle skimmer and make it to rise, the molten iron face of taking off in slag plate and the mixed iron blast is remained basically stable.

2. handle and stretch into the district that skims before skimmer makes it.

3. skim.Handle and to contract after skimmer makes it, under the effect of the depress wheel of screwdown gear, force deslagging head (plate) to penetrate slag liquid (see figure 6), deslagging head is skimmed by movement locus shown in Figure 7.

4. through the skimming of such repeated multiple times, treat slag liquid remove clean after, molten iron just can be emitted from tapping hole, for making steel use.
