Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1-2, a circular carbon-blowing gun comprises a core body 5, wherein the core body 5 is made of a carbon steel pipe. A multi-section ceramic tube 6 is arranged in the core body 5, and a carbon steel ceramic tube 7 is arranged at the head end of the ceramic tube 6. The gun core is made of ceramic materials, is smooth and wear-resistant, and facilitates carbon powder injection.

An inner wall pipe 4 is sleeved outside the core body 5, and a circular blowing cavity is formed between the core body 5 and the inner wall pipe 4; the outer wall pipe 2 is sleeved outside the inner wall pipe 4, the head ends of the inner wall pipe 4 and the outer wall pipe 2 are connected through a fixing ring 1, and the fixing ring 1 is made of manganese steel; the cooling cavity is formed by the inner wall pipe 4, the outer wall pipe 2 and the fixing ring 1, the marine riser 3 is arranged in the cooling cavity, and the rear part of the outer wall pipe 2 is connected with the water inlet outer wire 8 and the water outlet outer wire 9. The cooling water enters the cooling cavity from the water inlet outer wire 8, flows to the gun head and then turns back, and is discharged from the water outlet outer wire 9.

The tail end of the outer wall pipe 2 is connected with one of the flanges of the flange 10 through the connecting outer pipe 16, the rear part of the core body 5 is connected with the other flange of the flange 10, the core body 5 is fixed with the water cooling assembly outside through the flange 10 during assembly, the gun core is more conveniently replaced by the connecting mode, and the core is easily pulled out.

The tail end of this application core 5 is connected through connecing public female head soon with helping the ware 11 that blows, convenient dismantlement. Being equipped with in the blow-assisted device 11 and being the person in charge 111 and the carbon pipe 112 that blows that certain angle set up each other intercommunication and being, being responsible for 111 outer silk 13 of the end-to-end connection of 111, outer silk 13 is equipped with wind head 12 with the one end of being responsible for 111 and being connected, and the other end of outer silk 13 is equipped with the pipe cap, and the setting of wind head 12 can make and help blowing gas formation vortex, can control the trend of air current on the one hand, makes to spray more evenly, and on the other hand can prevent to sweep the dead angle, realizes more economical and reasonable confession carbon.
