Abstract
The utility model relates to a double-side slag-dragging harrow, comprising two slag harrow shafts (1) and two big slag harrows (2) fixed on the lower part of two slag harrow shafts (1), two small slag harrows (3) are arranged on the back of the two big slag harrows (2). Without the need to change the position of the slag harrow in the molten iron level, that is to say, without the need to move the slag harrow shaft and change the horizontal position of the transmission box above the slag harrow shaft, the slag-dragging blind spot can be eliminated through once combination dragging by using the big slag harrows and once combination dragging by using small slag harrows, thereby improving the slag dragging efficiency considerably.
Description
Technical field
The utility model relates to a kind of slag rake of swinging dragveyer.Described swinging dragveyer is a kind of special equipment that is used to clear up ladle (jar) liquid level scum silica frost.
Background technology
The same applicant of present patent application has proposed the utility application that name is called " a kind of molten iron drags for the special-purpose slag rake of slag " on January 10th, 2005 to Patent Office of the People's Republic of China, and application number is 200520000290.6.Should comprise slag harrow shaft and the riser that is fixed in the slag harrow shaft lower end at the special-purpose slag rake of patent application formerly, be connected with base plate, be connected with front end-plate and end plate respectively in the rear and front end of base plate in the riser lower end.Riser, end plate, base plate are formed the container of a two sides opening, are used for storing left and right sides slag rake and drag for the slag process in revolution and drive the bits that flock together.It is big to have the slag capacity, the characteristics that scarfing cinder efficient is high.
The applicant finds in practice, in dragging for the slag process, because the slag harrow shaft that is used to connect transmission case and slag rake is in the center of ladle (jar) all the time, the zone that the revolution of slag rake is covered is changeless, turns round the Zone Full that can not cover the molten iron liquid level through the primary slag rake.Therefore, produce the problem of dragging for the slag dead band or being called the blind area at the two slags rake back side.Solve the current practice of dragging for slag in the dead band and be conversion slag rake in the position of molten iron liquid level, by twice even repeatedly drag for the purpose that slag reaches basic elimination dead band.But do like this and influenced the operating efficiency of dragging for slag.
The two sides slag rake that utility model content technical problem to be solved in the utility model provides a kind of new structure drags for the slag dead band in order to elimination, improves and drags for slag efficient, overcomes the deficiency of above-mentioned patent application formerly.
In order to address the above problem, the utility model has adopted following technical scheme.
A kind of two sides slag rake mainly comprises two slag harrow shafts and two big slag harrows that are individually fixed in two slag harrow shaft lower ends, it is characterized in that: be respectively arranged with two small slag harrows at the back side of two big slag harrows.
After adopting the technical program, needn't change slag rake in the position of molten iron liquid level, promptly needn't mobile slag harrow shaft and the horizontal level of slag harrow shaft upper end transmission case, utilize big slag harrow to close up and drag for slag once, small slag harrow closes up and drags for slag and once can eliminate and drag for the slag dead band then, has therefore improved greatly and has dragged for slag efficient.
Description of drawings
Fig. 1 is the structural representation that the utility model small slag harrow closes up state.
Fig. 2 is the structural representation that the utility model big slag harrow closes up state.
The specific embodiment
As shown in Figure 1, 2, embodiment of the present utility model mainly comprises two slag harrow shafts 1 and two big slag harrows 2 that are individually fixed in two slag harrow shafts, 1 lower end.Be fixed with two small slag harrows 3 respectively at the back side of two big slag harrows 2.
The rotation under slag harrow shaft drives of described slag rake drives respectively that two big slag harrows close up or two small slag harrows close up.
The slag process is once dragged in narration below:
(1), small slag harrow sinks to ladle (jar) liquid level closing up under the state, two big slag harrows 2 close up poly-slag, slag inclusion gradually under slag harrow shaft drives;
(2), slag rake rises, and leaves ladle (jar) mouth, small slag harrow closes up, big slag harrow is opened slagging;
(3), slag rake sinks to ladle (jar) liquid level once more, two slag harrow shaft opposite spins drive time two small slag harrows 3 and close up poly-slag, slag inclusion gradually;
(4), slag rake rises, and leaves ladle (jar) mouth, small slag harrow is opened slagging.
Claims (1)
1, a kind of two sides slag rake mainly comprises two slag harrow shafts (1) and is individually fixed in two big slag harrows (2) of two slag harrow shafts (1) lower end, it is characterized in that: be respectively arranged with two small slag harrows (3) at the back side of two big slag harrows (2).
