Description
Technical field
The utility model relates to ironmaking technology field more particularly to a kind of connecting device of oxygen lance.
Background technique
It in iron industry blast furnace casting, is opened when tapping machine can not normally bore iron mouth, it is necessary to use the boiled iron of oxygen lance
Mouthful.The method generallyd use is first willHigh pressure rubber hose and DN15 oxygen lance connect, or with it is fairly simple slightly
Rough fastening means is attached with oxygen lance, then gos deep into oxygen lance in iron mouth pore passage, after opening oxygen valve, is controlled
Oxygen pressure lights oxygen lance in duct, to positive iron mouth pore passage center, iron mouth is boiled, in the remaining fixed length of oxygen lance
Extraction when spending.
However, the mode that above-mentioned burning tapping outlet has the disadvantage in that 1, connect with hose with oxygen lance, when operation, is direct
Oxygen lance, operator's face iron mouth are held, splash ornamental work of iron when burning iron mouth is easy burn, and there are larger security risks, and are pulling out
When oxygen lance, in order to ensure safety, residue length is excessive, and oxygen lance is caused to waste；2, the mode connected with simple connection method, blows
The sealing of oxygen pipe junction is bad, and oxygen is caused to run leakage, not only can waste of resource, but also the fluctuation of poorly sealed overpressure is big, holds
Tempering is easily caused, there are larger security risks.
Summary of the invention
The purpose of this utility model be solve the connection type of current oxygen lance there are larger security risk, will cause oxygen blast
Pipe wastes and be easy to cause oxygen to run leakage the technical issues of waste of resource, provides a kind of connecting device of oxygen lance.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of connecting device of oxygen lance comprising connecting sleeve, supervisor, socket joint centrum connector, rubber gasket and locking
Nut, the supervisor are divided into two sections, are made of straight section and segmental arc, in which: straight section one end of the supervisor is oxygen inlet, directly
The other end of section and one end of segmental arc connect, and the other end of segmental arc is connect with connecting sleeve, and socket joint centrum connector is set to
In the connecting sleeve and bottom of socket joint centrum connector and one end of connecting sleeve connect, rubber gasket be set to connecting sleeve with
In the gap that socket joint centrum connector is formed and it is located at close to the position of socket joint centrum connector bottom, locking nut is set to connector sleeve
The other end of pipe side wall.
Optionally, the connecting sleeve is DN20 seamless steel pipe, is responsible for as DN15 seamless steel pipe.
Optionally, the length of the connecting sleeve is 300mm；The straight section length of the supervisor is 1200mm, arc segment length
Degree is 575mm, and the radian of segmental arc is 135 °；The taper of the socket joint centrum connector is 1:10.
The beneficial effects of the utility model are:
Cone joint is accepted by setting and oxygen lance is inserted in the outside of undertaking cone joint when in use, can make to blow
Oxygen pipe and undertaking cone joint are efficiently coincide；By the way that rubber gasket is arranged, the sealing of contact surface can be well realized；Pass through
Locking nut is set, being stably connected with for oxygen lance and connecting device of oxygen lance may be implemented；It include segmental arc by setting supervisor,
Operative employee when burning the operation of iron mouth is allowed to substantially increase degree of safety in the side Tie Kou erect-position, remaining oxygen blast can also be shortened
The length of pipe improves the utilization rate of oxygen lance.Therefore, compared with the background art, the utility model is with light-weight, structure is simple
Compact, easy to operate, the leakage that oxygen lance will not be wasted, prevented oxygen, save oxygen resource, eliminate safety it is hidden
Suffer from, work efficiency is high, avoids the advantages that falling off and eliminate tempering hidden danger of oxygen lance in use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the partial enlarged view in the portion A in Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with drawings and examples.
As depicted in figs. 1 and 2, the connecting device of oxygen lance in the present embodiment includes connecting sleeve 1, supervisor 2, socket joint centrum
Connector 3, rubber gasket 4 and locking nut 5,2 points of the supervisor are two sections, are made of straight section and segmental arc, in which: the master
Straight section one end of pipe 2 is oxygen inlet, and the other end of straight section and one end of segmental arc connect, the other end and connector sleeve of segmental arc
Pipe 1 connects, and socket joint centrum connector 3 is set in connecting sleeve 1 and one end of the bottom of socket joint centrum connector 3 and connecting sleeve 1
Connection, rubber gasket 4 are set in the gap of connecting sleeve 1 and the formation of socket joint centrum connector 3 and are located at close to socket joint centrum
The position of 3 bottom of connector, locking nut 5 are set to the other end of 1 side wall of connecting sleeve, and oxygen lance 6 is inserted in socket joint when in use
The outside of the centrum connector 3 and end of oxygen lance 6 is contacted with rubber gasket 4.The other end and connecting sleeve 1 of segmental arc weld
It connects.
Wherein, the connecting sleeve 1 is DN20 seamless steel pipe, and supervisor 2 is DN15 seamless steel pipe.
In the present embodiment, the length of the connecting sleeve 1 is 300mm；The straight section length of the supervisor 2 is 1200mm, arc
