Description
Technical field
It the utility model is related to a kind of blast-furnace tuyere leading portion that handles and block up burnt device.
Background technology
In blast furnace ironmaking process, in the case that there is larger fluctuation or significantly checking in conditions of blast furnace, the coke inside air port
It can circle round to air port leading portion, be stopped between the big lid in air port and elbow air intake corner, this region is one section of dead band, stop
Coke will not be blown away, and this, which results in the air port, can not be observed and be analyzed, and processing method usually is by the rotation of peep-hole
Plug valve is closed, and cap is spied in back-out, and blowout coke is diffused by opening plug valve, and this method is relatively hazardous, easily causes plug valve pass
Do not fall and scaling loss blowing device, so as to cause the urgent damping down of blast furnace, furthermore larger coke can not be peeped from caliber is less at all
Blown out in window.There is stifled burnt, stifled slag in blast furnace air supply system peep-hole front end, do not reach band wind and handle, easily cause processing operation
When gas leak often occur, while stifled burnt, the stifled slag in multiple air ports causes blast furnace staying, in addition, attendant overhauls with coal gas,
Easily cause gas poisoning.Easy airborne dust, generation harsh noise, very big hidden danger is brought to safety in production during block clearing operation.While from
Angle of keeping the safety in production considers that it needs to improve.Therefore solve the defects of supply air system unimpeded, guarantee safe production, it is extremely urgent.
The content of the invention
For problem above, the utility model provides a kind of blast-furnace tuyere leading portion that handles and blocks up burnt device, can guarantee that air-supply
Situation in the normal air-supply of device and observation air port, solves the unimpeded difficult point of air-supply arrangement, drops fault rate during unimpeded operation
Low is 0, noiseless, and environmental protection effect is good, solves air-supply arrangement unimpeded, the safety problem of a large amount of leakage gas, is examined to safeguarding
The personnel of repairing offer convenience.
The purpose of this utility model is achieved in that a kind of blast-furnace tuyere leading portion that handles blocks up burnt device, including cock
Valve, plug valve are connected by sighting tube with air port board plug device, and the other end of plug valve is connected to a connecting tube by nut,
Connection pipe end sets snap joint, and snap joint is connected with the joint of air blower airduct.
After the utility model is tried out on blast furnace air supply system, blast-furnace tuyere leading portion blocks up coke installation and changes job specification,
Burnt maneuver processing air port is blocked up using processing blast-furnace tuyere leading portion and blocks up burnt process hazard factor reduction, and treatment people only needs 2 people, labor
Fatigue resistance is smaller, it is ensured that operating personnel's safety；Processing air port leading portion heap Jiao can be prevented completely and cause blast furnace checking or damping down.It is high
Stove air port leading portion blocks up coke installation system failure influence blast furnace staying number and is reduced to 0.Shown by operative practice, for blast-furnace tuyere
The improvement that leading portion blocks up coke installation system achieves success.Simultaneously effective avoid the gas poisoning safety triggered in processing procedure
Accident occurs.
Brief description of the drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is main structure diagram of the present utility model.
