Abstract
The utility model discloses a kind of Anti-backfire oxygen-combustion devices, including oxygen hose, oxygen rifle handle and burn oxygen pipe, the oxygen rifle handle includes inserting gun barrel and trachea；Slotting gun barrel one end closing, the other end connection burning oxygen pipe；Described trachea one end connects oxygen hose, and gun barrel, trachea and the T-shaped connection of slotting gun barrel are inserted in other end connection.Oxygen rifle handle by being arranged to the slotting gun barrel and trachea of T-shaped connection by the device, when one side high pressure oxygen passes through oxygen rifle handle, high pressure non-return area can be formed in the blind end for inserting gun barrel, when air source disconnects suddenly, high pressure non-return area can provide the instantaneous pressure for being directed toward and burning oxygen pipe, prevent tempering, effective guarantee safe operation；On the other hand, slotting gun barrel is held during operation and is also avoided that the oxygen hose interface touched on trachea, oxygen hose is reduced and loosens disconnection, ensure that the stability for burning oxygen operation.
Description
Technical field
A kind of a kind of metallurgical equipment of the utility model, and in particular to Anti-backfire oxygen-combustion device.
Background technology
During iron and steel smelting, frequently oxygen operation can be burnt using burning oxygen device.For example, ironmaking burns blast furnace taphole, burns the residual iron of major groove
Mouthful；Wicking surface of breathing freely during steel-making continuous casting to ladle ventilating seat brick purges and cleaning ladle nozzle, processing ladle cannot be just normally opened
Pour and tundish temperature low fever in packet eye drain；It is burnt when recycling steel scrap and cuts steel scrap etc..
Existing burning oxygen device sequentially connected oxygen hose, oxygen rifle handle and burning oxygen pipe as shown in Figure 1, be made up of.
When burning oxygen, operating personnel hold oxygen rifle handle operation, positioned at front end burning oxygen pipe can rapid scorification be gradually shortened, operating personnel
Grip position also can only gradually move afterwards, the oxygen hose positioned at rear end can be inevitably encountered during rear shifting, this structure has
When encounter oxygen hose connection loosely, suddenly disconnect be easy for occur tempering casualty accident.
Invention content
Purpose of utility model：The defects of in order to overcome the prior art, the utility model provide a kind of Anti-backfire oxygen-combustion device.
Technical solution：A kind of Anti-backfire oxygen-combustion device described in the utility model, including oxygen hose, oxygen rifle handle and
Oxygen pipe is burnt, the oxygen rifle handle includes inserting gun barrel and trachea；Slotting gun barrel one end closing, the other end connect the burning oxygen
Pipe；Described trachea one end connects oxygen hose, and gun barrel, trachea and the T-shaped connection of slotting gun barrel are inserted in other end connection.
Operation principle：The device inserts gun barrel and the T-shaped connection of trachea, when burning oxygen, from the hyperbaric oxygen of oxygen hose infeed
Gas during by oxygen rifle handle, can form high pressure non-return area, when air source disconnects suddenly in the closing one end for inserting gun barrel
When, high pressure non-return area can also provide the instantaneous pressure for being directed toward and burning oxygen pipe, so as to prevent being tempered.During operation, hand-holdable slotting gun barrel or
Person's trachea operation, when holding slotting gun barrel, oxygen hose can't be touched by, which being moved with the scorification for burning oxygen pipe, after grip position, connects
Head；During hand-held trachea, even if oxygen hose is disconnected cut-out air source, the high pressure non-return area for inserting gun barrel blind end still is able to provide
Instantaneous pressure prevents the tempering of oxygen rifle handle from hurting sb.'s feelings
Advantageous effect：The utility model inserts gun barrel and trachea, trachea and slotting gun barrel by the way that oxygen rifle handle is arranged to
T-shaped connection when one side high pressure oxygen passes through oxygen rifle handle, can form high pressure non-return area, air source in the blind end for inserting gun barrel
When disconnecting suddenly, high pressure non-return area can provide the instantaneous pressure for being directed toward and burning oxygen pipe, prevent tempering, effective guarantee safe operation；
On the other hand, slotting gun barrel is held during operation and is also avoided that the oxygen hose interface touched on trachea, reduces oxygen hose pine
It is de- to disconnect, it ensure that the stability for burning oxygen operation.
Description of the drawings
Fig. 1 is existing burning oxygen apparatus structure schematic diagram；
Fig. 2 is the utility model Anti-backfire oxygen-combustion apparatus structure schematic diagram.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Fig. 2, a kind of Anti-backfire oxygen-combustion device, including oxygen hose 1, oxygen rifle handle 2 and burns oxygen pipe 3, oxygen rifle
Handle 2 includes inserting gun barrel 21 and trachea 22；The closing of 21 one end of gun barrel is inserted, oxygen pipe 3 is burnt in other end connection；22 one end of trachea connects
Oxygen hose 1 is connect, gun barrel 21, trachea 22 and slotting 21 T-shaped connection of gun barrel are inserted in other end connection.
Galvanized pipe can be used during making and be welded into oxygen rifle handle 2, made of two galvanized pipes, gun barrel is inserted in a conduct
21, another is used as trachea 22.Closing is welded with blind plate in slotting 21 one end of gun barrel, one hole of cutting of cutting knife is used on side wall, will connect
Tracheae 22 is welded on hole.1 oxygen hose 1 of oxygen hose is directly accessed from live oxygen packet, trachea 22 and oxygen hose 1
One end outer diameter of connection is slightly larger than the internal diameter of oxygen hose 1, in this way, oxygen hose 1 can be socketed in by interference fit connects gas
On pipe 22, increase the firmness of its connection.It is same way, it is also possible to outer in one end that trachea 22 is connect with oxygen hose 1 setting
Screw thread sets internal thread on oxygen hose 1, and oxygen hose 1 is screwed onto on trachea 22.
When burning oxygen, 22 operation of slotting gun barrel 21 or trachea is held, even if encountering the situation that oxygen hose loosens, inserts gun barrel
The high pressure non-return area that 21 closing one end is formed, which can provide instantaneous pressure, to be prevented from being tempered.Preferably, can by trachea 22 with
The position for inserting the connection of gun barrel 21 is arranged on one end 250-400mm that distance inserts the closing of gun barrel 21, and on the one hand there are one close for energy in this way
Suitable gripping length, is conveniently operated.On the other hand, the effect in high pressure non-return area can also be maximized.It is of course also possible to making
When inserting gun barrel 21, galvanized pipe boring is gradually expanded into one end to other end internal diameter, as, slotting gun barrel 21 after making it is interior without leave
Closing one end becomes larger to the one end being connect with burning oxygen pipe 3.When air source is sudden shut off, the internal diameter bigger of oxygen pipe one end is burnt,
Air-flow can prevent accident appearance to the big one end play of internal diameter, the phenomenon that so as to which trachea one end be avoided to be tempered.
The above is only the preferred embodiment of the utility model, it should be pointed out that in the design for not departing from the utility model
Under the premise of, several deductions or replacement can also be made, these, which are deduced or substitute, is regarded as the scope of protection of the utility model.
