Abstract
The utility model relates to a single slag rake rotating slag conveyor which comprises a suspension arm (1) and a power case (2) fixed at the front end of the suspension arm (1), wherein a rotating rake (6) is fixed at the lower end of a rotating shaft (7), and the upper end of the rotating shaft (7) is connected with the power case (2); a fixing rake (4) is fixed on the power case (2) through a fixing rod (3). By adopting the technical scheme, only the rotating rake rotates around the shaft and the fixing rake only has the action for matching with a baffle plate. When the utility model is used, the rotating shaft is positioned in the center of a circle of the liquid level of an iron ladle, and the rotating track of the rotating rake is in a standard circle; thereby, the rotating rake can cover 100 percent of the area of the liquid level of the iron ladle and slag conveying efficiency can be increased by more than 10 percent.
Description
Technical field
The utility model relates to a kind of swinging dragveyer, is a kind of special equipment that is used to clear up ladle (jar) liquid level scum silica frost, belongs to metallurgical special equipment field.
Background technology
Publication number is 1546259 Chinese patent " efficient slag skimming method of a kind of molten iron and isolated plant thereof ".Disclose a kind of slag rake swinging and dragged for slag method and special equipment thereof.This technology is compared with traditional reciprocating type slag skimming method, and iron loss obviously reduces, and scarfing cinder rate and production efficiency increase substantially.
But a pair of slag rake of this patent application all rotates, because slag harrow shaft decentraction, the shape that the revolution of two slags rake covers the molten iron liquid level is actually an ellipse, can not cover the ladle liquid level fully, as shown in Figure 3, the coverage rate that the rake revolution of two slags covers the molten iron liquid level only is 86.6%, therefore this dragveyer drag for the slag rate still can not be satisfactory.
Address this problem and can also take following scheme, promptly the slag rake is carried out particular design, a slag rake is along the rotation of ladle center during use, and another slag rake is along an eccentric shaft rotation with respect to the ladle center.But its structure more complicated still needs further research at present.
Single slag rake that utility model content technical problem to be solved in the utility model provides a kind of new structure rotates the revolution dragveyer, make the moving liquid surface shape that covers of slag scraping more near the garden shape of ladle liquid level, drag for slag efficient with further raising, overcome the defective of above-mentioned existing procucts and technology.
In order to address the above problem, the utility model has adopted following technical scheme.
A kind of single slag rake rotates the revolution dragveyer, comprises cantilever and the headstock that is fixed in the cantilever front end, and its special feature is: rotary harrow is fixed in the lower end of rotating shaft, and the rotating shaft upper end is connected with headstock; Fixing rake is fixed on the headstock by fixed bar.
Rear end at fixing rake is provided with baffle plate.
After adopting above technical scheme, have only rotary harrow to sway, fixedly rake only plays the mating reaction of baffle plate.When using the utility model, rotating shaft is positioned at the home position of ladle liquid level, and the rotation of rotary harrow is a standard circular, therefore can cover the ladle liquid level near 100% area, drags for slag efficient and improves more than 10%.

The specific embodiment
As shown in Figure 1, the utility model comprises cantilever 1, is fixed in the headstock 2 of cantilever 1 front end.Rotary harrow 6 is fixed in the lower end of rotating shaft 7, and rotating shaft 7 upper ends are connected with headstock 2; The rotational power of rotating shaft 7 comes automatic power box 2.Fixing rake 4 is fixed on the headstock 2 by fixed bar 3.
Rear end at fixing rake 4 is provided with baffle plate 5.The upper surface of this baffle plate 5 is positioned at the below of rotating shaft 7.
During the utility model work, rotary harrow 6 drives lower edge ladle liquid level in rotating shaft 7 and rotates near a week, slag is brought between rotary harrow 6 and the fixing rake 4 pulls out.
Fig. 3 is the moving track schematic diagram of existing dragveyer slag scraping, the movement locus of slag rake 9 is found out from Fig. 3, the shape that the revolution of two slags rake covers molten iron liquid level 10 is actually an ellipse, can not cover ladle liquid level 8 fully, through measuring and calculating, the coverage rate that the revolution of two slags rake covers the molten iron liquid level only is 86.6%.
Fig. 2 is the moving track schematic diagram of the utility model embodiment slag scraping.The operation area of rotary harrow reaches and almost overlaps with the ladle liquid level as seen from the figure.
Claims (2)
1, a kind of single slag rake rotates the revolution dragveyer, comprises cantilever (1) and is fixed in the headstock (2) of cantilever (1) front end, and it is characterized in that: rotary harrow (6) is fixed in the lower end of rotating shaft (7), is connected with headstock (2) on the rotating shaft (7); Fixing rake (4) is fixed on the headstock (2) by fixed bar (3).
2, single slag rake as claimed in claim 1 rotates the revolution dragveyer, and it is characterized in that: the rear end at fixing rake (4) is provided with baffle plate (5).
