Abstract
The utility model discloses a coal-oxygen lance with a switch for hot-repair of a molten steel tank in a steelmaking process. The oxygen gun body inner tube 1 is sleeved in the gas gun body outer tube 2, the inner tube pivot 3 is circumferentially arranged on the outer wall of the oxygen gun body inner tube 1, one end of the frame 4 is fixedly connected with the gas gun body outer tube 2, the adjusting switch 6 is fixedly connected on the upper part of the frame 4, two ends of the adjusting switch are connected with the hose 7 and connected with the oxygen gun body inner tube 1 through the pipeline 5, the adjusting switch 9 is fixedly connected on the lower part of the frame 4, and two ends of the adjusting switch are connected with the hose 10 and connected with the gas gun body outer tube 2 through the pipeline 8. The gas outlet of the coal-oxygen gun is aligned to the hot repair molten steel tank, and adjusting switches 6 and 9 are adjusted, so that external oxygen and coal gas respectively pass through an oxygen gun body inner tube 1 and a coal gas gun body outer tube 2 and are mixed into coal-oxygen mixed gas to be combusted in the hot repair molten steel tank, and impurities in the molten steel tank are removed. The coal-oxygen lance with the switch can be popularized to the maintenance of various molten steel tanks.
Description
Technical field
The utility model relates to a kind of coaloust-oxygen gun of the belt switch that uses when being applied to hot repair molten steel jar in the smelter process for making.
Background technology
The coal gas rifle that in the past was used in hot repair molten steel jar is belt switch not, need the manually-operated coaloust-oxygen gun in use, the one man operation coaloust-oxygen gun, another people operates coal gas and oxygen switch a long way off, if two kinds of operations are inharmonious, can bring potential safety hazard, not only inefficiency, and waste coal gas and oxygen, increase energy resource consumption contaminated environment again.
In order to solve the technical problem that prior art exists, it is the coaloust-oxygen gun of one, easy to operate, belt switch that the saving energy resource consumption is light and handy again that the utility model provides a kind of coal gas, oxygen by-pass cock and the coaloust-oxygen gun body of a gun.
The technical solution adopted in the utility model is: pipe box is contained in the inner chamber of coal gas body of a gun outer tube in the oxygen body of a gun of design, in the oxygen body of a gun one of pipe with the fixed sealing of inner tube plate, and at one of coal gas body of a gun outer tube with the fixed sealing of outer tube ring flat-plate, the pipe fulcrum is cemented on the outer wall of pipe in the oxygen body of a gun in a plurality of, the coal gas body of a gun outer tube that is sealed with the outer tube ring flat-plate is fixed on the framework, oxygen by-pass cock and gas regulator joint switch are fixedly mounted on this framework simultaneously, in connecting the oxygen body of a gun, oxygen channel manages for one of the oxygen by-pass cock, its other end connects oxygen hose, one of the coal gas by-pass cock connects coal gas body of a gun outer tube through gas piping, and the other end of coal gas by-pass cock connects gas pipe hose.
The technique effect that adopts the coaloust-oxygen gun of a kind of belt switch that as above technical scheme provides compared with prior art to obtain is:
1. save 50% operating personnel, convenient safety again;
2. reduce by 30～40% coal gas and oxygen expenditure.
Description of drawings
Accompanying drawing is the coaloust-oxygen gun structural representation of a kind of belt switch described in the utility model, also is specification digest accompanying drawing of the present utility model.
The specific embodiment
The specific embodiment of the present utility model is made the detailed description in a step below in conjunction with accompanying drawing.
As shown in drawings, the coaloust-oxygen gun of a kind of belt switch described in the utility model by manage 1 in the oxygen body of a gun, coal gas body of a gun outer tube 2, interior pipe fulcrum 3, framework 4, pipeline 5 or 8, by-pass cock 6 or 9, flexible pipe 7 or 10, inner tube plate 11, outer tube ring flat-plate 12 constitute.Pipe 1 is sleeved in the coal gas body of a gun outer tube 2 in the oxygen body of a gun, one of pipe 1 and the 11 fixed and sealings of inner tube plate in the oxygen body of a gun, the big footpath of outer tube ring flat-plate 12 is cemented in an end and the sealing of coal gas body of a gun outer tube 2, and the path of outer tube ring flat-plate 12 is cemented on the outer wall of pipe 1 in the oxygen body of a gun and sealing.Pipe fulcrum 3 circumferential arrangement also were cemented on the outer wall of pipe 1 in the oxygen body of a gun in N (integer of N＞1) was individual, and the height of interior pipe fulcrum 3 can be selected in and can guarantee in the oxygen body of a gun that it is scope that pipe 1 can freely insert coal gas body of a gun outer tube 2.One end of framework 4 and coal gas body of a gun outer tube 2 concrete mutuallies (as welding), by-pass cock 6 is the oxygen by-pass cock, it is cemented in the top of framework 4, one end of by-pass cock 6 is communicated with in the oxygen body of a gun through pipeline 5 manages 1, pipeline 5 is the oxygen therapy feed channel, the other end of by-pass cock 6 is connected flexible pipe 7, and flexible pipe 7 is oxygen therapy gas flexible pipe.Pipeline 8 is defeated gas piping to of by-pass cock 9 through pipeline 8 connection coal gas body of a gun outer tubes 2, and flexible pipe 10 is connected in the other end of by-pass cock 9, and flexible pipe 10 is for failing gas pipe hose.
During enforcement, the molten steel jar of need hot repair is placed the workplace, operating personnel close an openend of aiming at (comprising oxygen and coal gas) the molten steel jar of giving vent to anger of the coaloust-oxygen gun of belt switch earlier by-pass cock 6 or 9, and flexible pipe 7 or 10 are connected source of oxygen and coal gas source respectively.Mobile framework 4, the have good positioning position of coaloust-oxygen gun, open by-pass cock 6 or 9 simultaneously, enter pipe 1 and coal gas body of a gun outer tube 2 in the oxygen body of a gun respectively from the oxygen of flexible pipe 7 and from the coal gas of flexible pipe 10, at this moment, oxygen and coal gas in the oxygen lance body of a gun, manage 1 and the port of export of coal gas body of a gun outer tube 2 be mixed into the molten steel jar internal combustion of coal oxygen gas mixture at high temperature (about 800～1000 ℃), the flare height of mist of burning and color or flare temperature can be regulated by the degree that operating personnel open by-pass cock 6 or 9, operating personnel are according to the situation in the molten steel jar, at any time hot repair is carried out to the molten steel jar in mobile coaloust-oxygen gun position, reaches the purpose of this utility model.
