Description
Technical field
the utility model belongs to metallurgical casting industry desulfurizer field, relates in particular to a kind of desulfurizing iron and uses whipping appts.
Background technology
(Kambara Reactor) doctor treatment is a kind of desulfurizing iron method that adopts the mechanical stirring mode.Iron (steel) water when carrying out desulfurization, adds a certain amount of sweetening agent in bag, and requires itself and iron (steel) water thorough mixing, reaction.This just need carry out mechanical stirring to iron (steel) water.Because the good desulfurization dynamics of KR (Kambara Reactor) stirring desulphurization, thereby obtain the extensive concern of domestic and international iron and steel enterprise.
have a kind of mechanical stirring device at present, and its stirring-head is processed by refractory materials, is shaped as cruciform; Promptly around stirring-head, be provided with four agitating vanes; Realize stirring through rotation, but above-mentioned stirring-head because all adopting welded-steel plate construction, agitating vane obviously rises the cost of agitating vane to iron (steel) water; In addition, the steel plate type agitating vane neither be very desirable to the adherence of refractory materials.
The utility model content
the utility model is intended to overcome the weak point of prior art and provides a kind of simple in structure, long working life, and desulfurizing iron with low cost is used whipping appts.
are for solving the problems of the technologies described above; The utility model is achieved in that desulfurizing iron uses whipping appts, the stir shaft that it comprises flange connector, be fixedly connected with said flange connector, with the affixed agitating vane in stir shaft bottom, be assigned in the refractory masses on stir shaft and the agitating vane; Said agitating vane comprises first wire netting and second wire netting; Between said first wire netting and second wire netting, be provided with the refractory materials interlayer.
as a kind of preferred version, the utility model can be fixed with interior pipe in said stir shaft.
for increasing structural strength, as another kind of preferred version, the utility model is fixed with stiffening web between said first wire netting and second wire netting.
further, the said agitating vane of the utility model can be selected the right-angled trapezium body.
the utility model is provided with first wire netting and second wire netting, and between said first wire netting and second wire netting, is furnished with the refractory materials interlayer through the design again to agitating vane.Like this, promptly alleviate the overall weight of whipping appts, reduced manufacturing cost simultaneously again.Be increased dramatically the work-ing life of whipping appts.

Among
figure: 1, flange connector; 2, stir shaft; 3, interior pipe; 4, agitating vane; 5, refractory masses; 6, first wire netting; 7, second wire netting; 8, refractory materials interlayer; 9, stiffening web; 10, skeleton.
Embodiment
are like Fig. 1 and shown in Figure 2; Desulfurizing iron is used whipping appts, the stir shaft 2 that it comprises flange connector 1, be fixedly connected with said flange connector 1, with the affixed agitating vane 4 in stir shaft 2 bottoms, be assigned in the refractory masses 5 on stir shaft 2 and the agitating vane 4; Said agitating vane 4 comprises first wire netting 6 and second wire netting 7; Between said first wire netting 6 and second wire netting 7, be provided with refractory materials interlayer 8.
the utility model fixedly is furnished with skeleton 10 on agitating vane 4 and stir shaft 2.Skeleton 10 is coated by refractory masses 5.
Pipe 3 in
the utility model can be fixed with in said stir shaft 2.
for increasing the whole structural strength of agitating vane, referring to Fig. 2, the utility model can be fixed with stiffening web 9 between said first wire netting 6 and second wire netting 7.
referring to Fig. 2, the said agitating vane 4 of the utility model is the right-angled trapezium body.
The above is merely the preferred embodiment of the utility model
, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
