Abstract

The utility model relates to a lateral starting revolving slag conveyor which comprises a suspension arm (1), a power case (2) fixed at the front end of the suspension arm (1), and two slag rakes which are installed on the power case (2) through slag rake shafts, wherein the slag rake shafts are arranged tandem along the trend of the suspension arm (1), and the slag conveying starting positions of the two slag rakes are at one side of the suspension arm (1). The liquid surface shape covered by the motion of the slag rakes approaches to the actual liquid surface shape of an iron ladle which is a tilting state. When the iron ladle tilts with an angle of 45 DEG, the slag rake covering rate is 61.24 percent when the slag rakes convey slag in a forward direction, and the slag rake covering rate reaches 84.5 percent when the slag rakes convey slag in a lateral direction; the slag conveying rate is increased by 23.26 percent.

Description

The initial revolution dragveyer of side direction

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.

Arrange but a pair of slag rake of this patent application is the left and right sides at the cantilever front end, drag for the dead ahead of slag original position at cantilever.Because the iron water amount in the ladle is different when dragging at every turn, in order to make its liquid level, dragging for the slag certain angle of all ladle will being tumbled as last as far as possible near bag mouthful so that more easily from a bag mouthful scarfing cinder.As a rule, before and after being, the liquid level of ladle lacks the ellipse of (from the dragveyer direction) about length, and the dragveyer revolution of adopting above-mentioned slag rake aligning method is when dragging for slag, and one of the moving molten iron liquid level that covers of slag scraping is long and that front and back are short is oval or be similar to circle about as shown in Figure 2.Therefore, the drag for slag rate of existing dragveyer under the ladle rollover conditions is under some influence, and need move a certain distance backward and solves by dragging in the slag process driving box, increased a kinematic pair.

If the dragveyer structure is installed on the arm of excavator, also can addresses the above problem by moving of excavator or its arm, but still have many technical problems to need to solve.

Utility model content technical problem to be solved in the utility model provides a kind of initial revolution dragveyer of side direction of new structure, make the moving liquid surface shape that covers of slag scraping more near the actual down liquid surface shape of ladle rollover conditions, 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.

The initial revolution dragveyer of a kind of side direction, comprise cantilever, be fixed in the headstock of cantilever front end and be installed in two slags rake on the headstock by slag harrow shaft, its special feature is: slag harrow shaft is arranged along the back that steps forward of cantilever, two slags rake drag for the side of slag original position at cantilever.

After adopting above technical scheme, two slags rakes drag for the side of slag original position at cantilever, slag rake closed position is at opposite side, as shown in Figure 3, the moving liquid surface shape that covers of slag scraping is more near the actual down liquid surface shape of ladle rollover conditions.When ladle is tumbled 45 ° the time, through measuring and calculating, the slag rake coverage rate that slag rake forward drags for slag is 61.24%, and the initial coverage rate of dragging for slag of side direction reaches 84.5%, drags for the slag rate and has improved 23.26%.

Fig. 3 is the moving track schematic diagram of the utility model embodiment slag scraping.

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 and is installed in two slags rake on the headstock 2 by slag harrow shaft.Before slag harrow shaft 3 and back slag harrow shaft 6 arrange along the back that steps forward of cantilever 1, corresponding, two slags rake promptly before slag rake 4 and back slag rake 5 drag for the side of slag original position at cantilever 1.

The preceding slag rake 4 of slag harrow shaft 3 and slag harrow shaft 6 lower ends, back and back slag rake 5 before being individually fixed in, the backward rotation with preceding slag harrow shaft 3 and back slag harrow shaft 6 begins rotation from cantilever 1 one sides and closes up poly-slag at opposite side.The rotational power of preceding slag harrow shaft 3 and back slag harrow shaft 6 comes automatic power box 2.

Fig. 2 is the moving track schematic diagram of existing dragveyer slag scraping, and Fig. 3 is the moving track schematic diagram of the utility model embodiment slag scraping.The movement locus of slag rake is found out from Fig. 2, Fig. 3, and slag rake work coverage rate 7 of the present utility model is more approaching with ladle liquid level 9 shapes of tumbling, and that is to say that the slag rate of dragging for of the present utility model is higher.Wherein 8 represent slag to harrow the original positions of dragging for slag.

Claims

1, the initial revolution dragveyer of a kind of side direction, comprise cantilever (1), be fixed in the headstock (2) of cantilever (1) front end and be installed in two slags rake on the headstock (2) by slag harrow shaft, it is characterized in that: slag harrow shaft is arranged along the back that steps forward of cantilever (1), two slags rake drag for the side of slag original position at cantilever (1).
