Description
Technical field
The invention belongs to metallurgical casting industry desulfurizer field, relate in particular to a kind of desulfurizing iron mechanical type whipping appts.
Background technology
KR(Kambara Reactor) doctor treatment is a kind of molten iron desulfurizing method that adopts the mechanical stirring mode.When iron (steel) water carries out desulfurization in bag, add a certain amount of sweetening agent, and require it fully to mix, react with iron (steel) water.This just need to carry out mechanical stirring to iron (steel) water.Because KR(Kambara Reactor) desulfurization kinetics characteristic that stirring desulphurization is good, thereby obtain the extensive concern of domestic and international iron and steel enterprise.
A kind of mechanical stirring device is arranged at present, its stirring-head is made by refractory materials, be shaped as cruciform, namely around stirring-head, be provided with four agitating vanes, by the stirring of rotation realization to iron (steel) water, but above-mentioned stirring-head inside arranges the pulvis transfer passage desulfuration efficiency of this device obviously is restricted.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art part and provides a kind of simple in structure, and is with low cost, the desulfurizing iron that desulfuration efficiency is high mechanical type whipping appts.
For solving the problems of the technologies described above, the present invention realizes like this.
Desulfurizing iron mechanical type whipping appts, the stir shaft that it comprises flange connector, be fixedly connected with described flange connector, with the affixed agitating vane in stir shaft bottom, be assigned in the refractory masses on stir shaft and the agitating vane; Between described agitating vane, be fixed with the first pulvis nozzle, the second pulvis nozzle, the 3rd pulvis nozzle and the 4th pulvis nozzle; The entrance of described the first pulvis nozzle, the second pulvis nozzle, the 3rd pulvis nozzle and the 4th pulvis nozzle communicates with the hollow channel of stir shaft respectively.
As a kind of preferred version, agitating vane of the present invention is four.
As another kind of preferred version, the first pulvis nozzle of the present invention, the second pulvis nozzle, the 3rd pulvis nozzle and the 4th pulvis nozzle angle each other are 90 o.
The present invention redesigns the whipping appts internal structure, is fixed with the first pulvis nozzle, the second pulvis nozzle, the 3rd pulvis nozzle and the 4th pulvis nozzle between agitating vane.Whipping appts is when work, can pass through stir shaft, the first pulvis nozzle, the second pulvis nozzle, the 3rd pulvis nozzle and the formed pulvis passage of the 4th pulvis nozzle, in melt, inject sweetening agent, simultaneously, by the high-level efficiency desulfurization of Stirring blade realization to molten iron.
