Embodiment 1
[0042] Such as figure 1 , 4 , 6 and 9, a high-performance spray gun used for molten iron injection pretreatment, including a connection section 1, a gun body section 2, and a spray section 3 connected in sequence, the connection section 1 includes a connecting flange 1.1, and the inside of the spray gun A spray gun main pipe 5 is provided, and the spray gun main pipe 5 is arranged between the connecting flange 1.1 and the bottom head 10 of the spray gun, and a swirl diffuser 4 is arranged between the gun body section 2 and the spray section 3, and the swirl diffuser 4 includes sequentially The upper circular platform body 4.1, the cylindrical body 4.2 and the lower rounded platform body 4.3 are connected, the upper round platform body 4.1 is connected with the gun body section 2, the lower inverted round platform body 4.3 is connected with the injection section 3, and the spray gun main pipe 5 and the head 10 are connected along the Two nozzles 8 are evenly opened in the circ...
Embodiment 2
[0048] Such as figure 1 , 4 , 6 and 10, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that:
[0049] The two nozzles 8 communicate with the main pipe 5 of the spray gun eccentrically, and the eccentric distance is e=XXXX~XXXX. 0≤e≤(D-d) / 2, wherein, D is the inner diameter of the main pipe 5 of the spray gun, and d is the inner diameter of the nozzle 8 .
Embodiment 3
[0051] Such as figure 1 , 4 , 6, and 11, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that:
[0052] There are 3 nozzles 8, and the three nozzles 8 communicate with the center of the spray gun main pipe 5.
