Abstract
The invention discloses an oxygen lance device at a burning iron notch in a stokehold of a blast furnace. The device comprises an oxygen pipeline and an oxygen blowing pipe, wherein the oxygen pipeline is communicated with an air inlet of a high pressure wire spirally-wound hose through a ball valve, the air outlet of the high pressure wire spirally-wound hose is communicated with the air inlet of a holding pipe, the air outlet of the holding pipe is communicated with the air inlet of a connecting pipe through a check valve, and the air outlet of the connecting pipe is communicated with the oxygen blowing pipe. The device disclosed by the invention has the advantages of high using safety and no reverse play of flames.
Description
Technical field
The present invention relates to ironmaking equipment technical field, be specifically related to burn iron mouth oxygen gun apparatus before a kind of State of Blast Furnace.
Background technology
The flat pricker of blast furnace front tapping fracture, or iron mouth difficulty is while opening, need to use oxygen gun apparatus by the oxygen spray in oxygen channel to iron mouth.The structure of the oxygen gun apparatus using is at present: comprising: the oxygen channel, the oxygen lance that are connected with oxygen, oxygen channel is connected with belt sebific duct by ball valve, belt sebific duct is managed with oxygen lance and is connected by gripping, between belt sebific duct and gripping pipe and ball valve, is all to fix by steel wire winding; When work, open ball valve, by oxygen lance by gripping manage, belt sebific duct is connected with oxygen channel, workman is dominated by hand again lives to grip pipe, thereby adjusts eject position and the angle of oxygen lance.The shortcoming of this oxygen gun apparatus is: in the use procedure of oxygen rifle, between belt sebific duct and gripping pipe easily there is explosion in interface, when after belt rubber hose coupling generation explosion, flame is easily altered to gripping pipe along oxygen lance, thereby the hand of controlling the operator that grip pipe is caused to burn, and equipment uses peaceful property low.
Summary of the invention
The object of this invention is to provide a kind of safe to use, can not occur before flame is altered a kind of State of Blast Furnace of phenomenon to burn iron mouth oxygen gun apparatus.
For achieving the above object, the present invention has adopted following technical scheme: before described a kind of State of Blast Furnace, burn iron mouth oxygen gun apparatus, comprise: oxygen channel, oxygen lance, oxygen channel is connected with the inlet mouth of high pressure steel wire spiral rubber hose by ball valve, the air outlet of high pressure steel wire spiral rubber hose is connected with the inlet mouth that grips pipe, the air outlet that grips pipe is connected with the inlet mouth of pipe connecting by vacuum breaker, and the air outlet of pipe connecting is connected with oxygen lance.
Further, burn iron mouth oxygen gun apparatus before aforesaid a kind of State of Blast Furnace, wherein: between high pressure steel wire spiral rubber hose and ball valve, high pressure steel wire spiral rubber hose with grip between pipe, grip between pipe and vacuum breaker, between vacuum breaker and pipe connecting respectively by holding straight coupling to be connected and fixed.
By the enforcement of technique scheme, the invention has the beneficial effects as follows: on the one hand, replace traditional belt sebific duct by high pressure steel wire spiral rubber hose, by high pressure steel wire spiral rubber hose and grip between pipe and all to have adopted end straight coupling to be threaded between high pressure steel wire spiral rubber hose and ball valve fixing, can effectively prevent like this explosion of high pressure steel wire spiral rubber hose joint simultaneously; On the other hand, by being provided with unidirectional vacuum breaker gripping between pipe and oxygen lance, even like this after high pressure steel wire spiral rubber hose joint generation explosion, also can effectively avoid flame to alter from oxygen lance the operator that burns to gripping pipe; Safe to use.
Accompanying drawing explanation
Fig. 1 is the structural representation that burns iron mouth oxygen gun apparatus before a kind of State of Blast Furnace of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, before described a kind of State of Blast Furnace, burn iron mouth oxygen gun apparatus, comprise: oxygen channel 1, oxygen lance 2, oxygen channel 1 is connected with ball valve 3, ball valve 3 is connected with the inlet mouth of high pressure steel wire spiral rubber hose 5 by first end straight coupling 4, the air outlet of high pressure steel wire spiral rubber hose 5 is connected with the inlet mouth that grips pipe 7 by the second end straight coupling 6, the air outlet that grips pipe 7 is connected with the inlet mouth of vacuum breaker 9 by the 3rd end straight coupling 8, the air outlet of vacuum breaker 9 is connected with the inlet mouth of pipe connecting 11 by the 4th end straight coupling 10, the air outlet of pipe connecting 11 is connected with oxygen lance 2, when work, open ball valve 3, oxygen channel 1 is connected with oxygen lance 2 by ball valve 3, high pressure steel wire spiral rubber hose 5, gripping pipe 7, vacuum breaker 9, pipe connecting 11, workman is dominated by hand again lives to grip pipe, thus eject position and the angle of adjustment oxygen lance 2, advantage of the present invention is: on the one hand, replace traditional belt sebific duct by high pressure steel wire spiral rubber hose, by high pressure steel wire spiral rubber hose and grip between pipe and all to have adopted end straight coupling to be threaded between high pressure steel wire spiral rubber hose and ball valve fixing, can effectively prevent like this explosion of high pressure steel wire spiral rubber hose joint simultaneously, on the other hand, by being provided with unidirectional vacuum breaker gripping between pipe and oxygen lance, even like this after high pressure steel wire spiral rubber hose joint generation explosion, also can effectively avoid flame to alter the operator's that burns to gripping pipe hand from oxygen lance, equipment is safe to use.
Claims (2)
1. before a State of Blast Furnace, burn iron mouth oxygen gun apparatus, comprise: oxygen channel, oxygen lance, it is characterized in that: oxygen channel is connected with the inlet mouth of high pressure steel wire spiral rubber hose by ball valve, the air outlet of high pressure steel wire spiral rubber hose is connected with the inlet mouth that grips pipe, the air outlet that grips pipe is connected with the inlet mouth of pipe connecting by vacuum breaker, and the air outlet of pipe connecting is connected with oxygen lance.
2. burn iron mouth oxygen gun apparatus before a kind of State of Blast Furnace according to claim 1, it is characterized in that: between high pressure steel wire spiral rubber hose and ball valve, high pressure steel wire spiral rubber hose with grip between pipe, grip between pipe and vacuum breaker, between vacuum breaker and pipe connecting respectively by holding straight coupling to be connected and fixed.
