Abstract
The utility model relates to a blast furnace micro cooler with a mud jacking hole. The blast furnace micro cooler comprises a micro cooler (1), the mud jacking hole (2), a steel flange (3), a water supply pipe (4) and a water draining pipe (5). The steel flange (3) is fixedly welded to a mounting hole of a furnace casing (7), the mud jacking hole (2) is arranged over the end face of the steel flange (3), the micro cooler (1) is installed on the steel flange (3) under the mud jacking hole (2), the water supply pipe (4) is arranged at the position of the center of the head of the micro cooler (1), and the water draining pipe (5) extends out of one side of the micro cooler (1). The blast furnace micro cooler can reduce damping down maintenance time of a blast furnace, reduces blast furnace maintenance cost and effectively protects micro cooling.
Description
Technical field
The utility model belongs to the smelting equipment technical field, particularly relates to a kind of blast furnace micro cooler with the mud jacking hole.
Background technology
The micro cooler (hereinafter to be referred as " chilly ") of using at blast furnace at present is not with the mud jacking hole, after the above cooling stave of blast-furnace bosh damages the enforcement sealing treatment that leaks, most of producers are all when the blast furnace periodical repair, install chilly at the cooling stave place that damages sealing, so that the liner at this position and furnace shell continue to be cooled off, keep the normal production of blast furnace and guarantee work-ing life.But, install chilly after, during for fear of normal production, the high-temperature molten slag iron in the chilly direct contact oven and washing away of Gas Flow and damage need open the mud jacking hole at chilly next door furnace shell, implement mud jacking and make the lining protection.Yet perforate has four drawbacks on furnace shell: the one, and, can reduce furnace shell intensity; The 2nd,, mud jacking hole and chilly certain distance arranged, it is not in place to chilly protection that mud jacking is made lining; The 3rd,, increase the engineering time; The 4th,, increase maintenance cost.
The utility model content
Technical problem to be solved in the utility model provides a kind of blast furnace micro cooler with the mud jacking hole, can reduce blast furnace staying servicing time, reduces the blast furnace maintenance cost, effectively protects chilly.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of blast furnace micro cooler with the mud jacking hole is provided, comprise micro cooler, the mud jacking hole, steel flanges, water service pipe, water shoot, cooling stave, furnace shell, be welded with steel flanges on the described furnace shell open holes, the mud jacking hole is arranged directly over the steel flanges head end, on the steel flanges under the mud jacking hole micro cooler is installed, micro cooler head center position has water service pipe, and micro cooler one side is stretched out a water shoot.
Off-centre is equipped with micro cooler on the steel flanges under the described mud jacking hole.
Described water shoot and water service pipe are communicated with in the micro cooler afterbody.
Beneficial effect
The utility model can reduce blast furnace staying servicing time, reduces the blast furnace maintenance cost, effectively protects chilly.

Embodiment 1
Such as Fig. 1 ~ shown in Figure 2, a kind of blast furnace micro cooler with the mud jacking hole comprises micro cooler 1, mud jacking hole 2, steel flanges 3, water service pipe 4, water shoot 5, cooling stave 6, furnace shell 7 is welded with steel flanges 3 on described furnace shell 7 open holess, directly over steel flanges 3 head end mud jacking hole 2 is arranged, on the steel flanges 3 under the mud jacking hole 2 micro cooler 1 is installed, micro cooler 1 head center position has water service pipe 4, and micro cooler 1 one sides are stretched out a water shoot 5.
Off-centre is equipped with micro cooler 1 on the steel flanges 3 under the described mud jacking hole 2.
Described water shoot 5 and water service pipe 4 are communicated with in micro cooler 1 afterbody.
1, opens ∮ 150mm open holes at the furnace shell of need installation micro cooler.
2, slag iron extremely can insert micro cooler 1 fully in the cleaning open holes, and inserts suitable stemming.
3, open holes is upwards inserted in the mud jacking hole 2 of micro cooler 1, guarantee that mud jacking hole 2 and stove are interior straight-through, to guarantee that grouting material can arrive the micro cooler front end, steel flanges 3 tack welds are fixed.
4, connect water coolant water service pipe 4 and water shoot 5 water flowings cooling.
5, with steel flanges 3 and furnace shell full weld.
6, will be with the weldless steel tube short tube of gas thread, one terminates on the mud jacking hole 2, and the other end connects valve, implements mud jacking, after pressing, valve-off.
7, next time, during mud jacking, detachable lower valve was implemented clear mud jacking hole 2 and mud jacking again.
Claims (3)
1. blast furnace micro cooler with the mud jacking hole, comprise micro cooler (1), mud jacking hole (2), steel flanges (3), water service pipe (4), water shoot (5), cooling stave (6), furnace shell (7), it is characterized in that: be welded with steel flanges (3) on described furnace shell (7) open holes, directly over steel flanges (3) head end mud jacking hole (2) arranged, on the steel flanges (3) under mud jacking hole (2) micro cooler (1) is installed, micro cooler (1) head center position has water service pipe (4), and micro cooler (1) one side is stretched out a water shoot (5).
