Description
Technical field
Blast furnace air-supply arrangement is the utility model is related to, specifically a kind of blast furnace with temperature pre-warning structure is straight
Blowpipe.
Background technology
In iron industry, air-supply apparatus of blast furnace is to smelt iron hot-air channel important between bustle pipe and blast furnace crucibe, and
Belly pipe is the key component being directly connected with blast furnace tuyere small sleeve again.If because belly pipe temperature is too high and cannot be timely
Effective emergency processing, belly pipe burn-through can be directly resulted in, and cause the urgent damping down of blast furnace, and urgent damping down can be caused in stove
Slag iron air-supply arrangement is poured in down a chimney, can be filled when serious to blast-furnace hot-air surrounding pipes, and may scaling loss stokehold miscellaneous equipment, cause
Serious economic loss.The mode for solving this problem at present is increase site operation personnel scene point inspection number, therefore is set " straight
Blowpipe temperature pre-warning system " realizes that automatic temperature monitoring is particularly important.
Utility model content
Temperature that the utility model easily occurs for belly pipe is high, rubescent, the problems such as burning, there is provided one kind carries temperature
The blast furnace belly pipe of early warning structure, makes belly pipe possess automatic temperature monitoring in normal use, and reach reduction
The controllability operation of accident rate.
The utility model solves the technical scheme that its technical problem uses：
A kind of blast furnace belly pipe with temperature pre-warning structure, including blow-through tube body, blow-through tube body include shell
Body, refractory lining layer, hot-air channel, two groups are embedded with the refractory lining layer of enclosure interior and is used to intert thermocouple
Conduit, external catheter end mouth draws hull outside, and two groups of conduits are distributed in inside belly pipe in 180 °, and every group has three to lead
Pipe, the terminal of every group of three conduits for temperature detecting point and point before, during and after point layout.
Using the utility model of above-mentioned technical proposal, compared with prior art, beneficial effect is：
When belly pipe works, thermocouple penetrates predetermined measuring point position inside belly pipe from the catheter port of belly pipe hull outside
Put, and thermocouple be connected to by Central Control Room by wire, be placed in enclosure interior be used for monitor thermocouple measured temperature biography
Deliver on the display screen of blast furnace Central Control Room, in order to accomplish the real-time monitoring of comprehensive temperature.Temperature control can be passed through simultaneously
Device sets the alarm temperature of belly pipe, the automatic alarm when temperature reaches setting value, the place sufficient in time to flushing and casting personnel
The time is managed, the generation for effectively solving the accidents such as the belly pipe caused by temperature is too high is rubescent, burns, is significantly reduced because straight
Blowpipe is rubescent, burns caused economic loss, timely excludes potential safety hazard.
Further, the utility model preferred scheme is：
Two groups of conduits, the external port of every group three totally six conduits concentrate a position to draw hull outside, one of which
Three conduits are arranged along belly pipe length direction, in straight tube form；Another group helically tubulose make terminal reach point position, institute
There is conduit to be welded and fixed with inner walls.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is Fig. 1 A-A direction views；
Fig. 3 is the position schematic diagram of six conduits；
Fig. 4 is Fig. 3 side structure schematic view；
In figure：Housing 1；Refractory lining layer 2；Hot-air channel 3；Conduit 4；First group of three measuring points 4-1,4-2,4-3；
Second group of three measuring points 4-4,4-5,4-6.
Embodiment
The utility model is elaborated below in conjunction with the embodiment that accompanying drawing provides.
Referring to Fig. 1 to Fig. 4, a kind of blast furnace belly pipe with temperature pre-warning structure, blow-through tube body by housing 1,
Refractory lining layer 2, the three parts of hot-air channel 3 are formed, and two groups of use are embedded with the refractory lining layer 2 inside housing 1
In the conduit 4 of interspersed thermocouple, the external port of conduit 4 is drawn outside housing 1, and two groups of conduits 4 are distributed in inside belly pipe in 180 °,
Every group has three conduits 4, the terminal of every group of three conduits 4 for temperature detecting point and point before, during and after point layout, specifically：
Two groups of conduits 4, the external port of every group three totally six conduits 4 concentrate a position to draw outside housing 1（See Fig. 3,
Fig. 4）, three conduits 4 of one of which along belly pipe length direction arrange, in straight tube form, three measuring points be respectively measuring point 4-1,
Measuring point 4-2, measuring point 4-3；Another group helically tubulose make terminal reach point position, three measuring points are measuring point 4-4, measuring point respectively
4-5, measuring point 4-6；All conduits 4 are welded and fixed and are embedded in refractory lining layer 2 with the inwall of housing 1.
The temperature point of six diverse locations, it can comprehensively monitor the temperature change of belly pipe each position.
The preferably feasible embodiment of the utility model is the foregoing is only, not thereby limits to power of the present utility model
Sharp scope, all equivalent structure changes made with the utility model specification and accompanying drawing content, is both contained in the utility model
Interest field within.
