Description
Technical Field
The utility model belongs to the technical field of the molten iron preliminary treatment, especially, relate to a rotatory jetting desulfurization stirring spray gun.
Background
The pretreatment desulfurization of molten iron is recognized as the best process for reducing the sulfur content in steel in a blast furnace-converter-continuous casting process flow. At present, from the current situation of molten iron desulphurization technology, the method can be divided into a KR stirring method and a blowing method. The single use of the above means can not meet the requirements of the molten iron desulphurization process on low cost and high efficiency to a certain extent, and the disadvantages of large iron loss, large molten iron temperature drop and the like exist when stirring desulphurization is adopted; when the injection is adopted, because the existing injection equipment is designed in a fixed mode, the problem that the utilization rate of the granular magnesium and the sulfur in the molten iron is low in the fashionable reaction is solved.
Disclosure of Invention
The utility model aims at providing a can integrate stirring method and blowing method as an organic whole, simple structure, convenient operation, desulfurization effect is good, long service life, the rotatory jetting desulfurization stirring spray gun of desulfurizer high-usage.
The utility model discloses a rotatory jetting desulfurization stirring spray gun, including the spray gun body, its characterized in that, the spray gun body include powder spraying inner tube, coolant conveying pipe and rotary driving axle, with rotary driving axle flange subassembly as an organic whole even, coolant import and coolant export, coolant, with the stirring vane of rotary driving axle lower part rigid coupling and set up the refractory material pouring layer on rotary driving axle and stirring vane, coolant conveying pipe suit in the outside of powder spraying inner tube, coolant import set up on the upper portion of coolant conveying pipe through the rotary joint, make coolant input channel form between coolant conveying pipe and the powder spraying inner tube, rotary driving axle suit in the outside of coolant conveying pipe, the coolant circulation hole that communicates with rotary driving axle is opened to the lower part of coolant conveying pipe, and a cooling medium outlet is formed on the lower part of the flange assembly and the rotary driving shaft, so that a cooling medium output channel is formed between the rotary driving shaft and the cooling medium conveying pipe.
The stirring blades are 2-6 stirring blades.
The cooling medium is nitrogen or cooling water.
The utility model has the advantages that: the utility model discloses owing to will stir and jetting integration as an organic whole, still increased cooling system simultaneously, not only will spout the mixed gas group that the desulfurization powder in the molten iron and the gas that jetting used formed and smash, increased the area of contact of desulfurization powder and molten iron, realize the purpose of desulfurization powder and molten iron intensive mixing, but also improved the life of desulfurization stirring spray gun in the industry mass production, the cost is reduced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an enlarged view of fig. 1.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the utility model discloses a rotatory jetting desulfurization stirring spray gun, including the spray gun body, its characterized in that, the spray gun body including inner tube 1, coolant conveyer pipe 3 and the rotation driving axle 5 of dusting, flange subassembly 4 as an organic whole is even with rotation driving axle 5, coolant import 11 and coolant export 10, coolant, with the stirring vane 7 of 5 lower part rigid couplings of rotation driving axle and the refractory material pouring layer 6 of setting on rotation driving axle and stirring vane, the effect of its flange subassembly is to pass the moment of torsion and is used for being connected with rotation driving axle actuating mechanism.
The cooling medium conveying pipe 3 is sleeved on the outer side of the powder spraying inner pipe 1, the cooling medium inlet 11 is arranged on the upper portion of the cooling medium conveying pipe 3 through the rotary joint 2, a cooling medium input channel is formed between the cooling medium conveying pipe 3 and the powder spraying inner pipe 1, the rotary driving shaft 5 is sleeved on the outer side of the cooling medium conveying pipe 3, a cooling medium through hole 9 communicated with the rotary driving shaft 5 is formed in the lower portion of the cooling medium conveying pipe 3, a cooling medium outlet 10 is formed in the lower portion of the flange assembly 4 and the rotary driving shaft 5, and a cooling medium output channel is formed between the rotary driving shaft 5 and the cooling medium conveying pipe 3.
The cooling medium of the utility model is nitrogen or cooling water. The cooling medium enters from the cooling medium inlet 11, passes through a channel formed between the powder spraying inner pipe 1 and the cooling medium conveying pipe 3, enters a channel formed between the cooling medium conveying pipe 3 and the rotary driving shaft 5 through the cooling medium through hole 9, and is discharged from the cooling medium outlet 10. Effectively prolonging the service life of the whole gun. In the figure, 8 is a discharge port of the powder spraying inner pipe 1, 12 is a feed port of the powder spraying inner pipe 1, and the direction indicated by the arrow in the figure 2 is the flow direction of the cooling medium.
Stirring vane 7 be 2 to 6 stirring vane, this embodiment gives three stirring vane's schematic diagram, its stirring vane 7's effect is that the mixed gas mass of gas formation that the desulfurization powder that will spout into in the molten iron and jetting use is smashed, the area of contact of increase desulfurization powder and molten iron realizes the purpose of desulfurization powder and molten iron intensive mixing.
The utility model discloses refractory material pouring layer 6's setting can play the guard action to the spray gun body, can extend to the molten iron when the spray gun body is used, and like this, refractory material pouring layer 6 can avoid the ablation of high temperature molten iron, improves desulfurization stirring spray gun life-span.
