Close case equipment technical field.
Background technology
Airtight distributing box is the nucleus equipment of blast furnace, the work condition environment in high temperature, high pressure and flue dust when it runs
Under, flue dust during blast furnace process easily enters the inside of pressure box, can be to parts such as pressure box internal gear, bearing, reductors
Cause damage.
There is simple annular seal space between traditional airtight distributing box housing and rotary barrel, be equipped with sealing ring.This sealing
At high temperature under high pressure, sealing function is poor, it is impossible to and effectively completely cut off smelting smoke dust, sealing ring easily wear out failure, and change and be not easy,
Airtight distributing box service life can be reduced.
Utility model content
The utility model purpose is to provide a kind of labyrinth seal structure for blast furnace material distribution pressure box, close by two-stage
Envelope, water conservancy diversion isolation is carried out to the flue dust for entering airtight distributing box, to improve the sealing of airtight distributing box, prevented because of sealing ring
Damage causes pressure box failure, solves problem present in background technology.
The technical solution of the utility model is：
A kind of labyrinth seal structure for blast furnace material distribution pressure box, led comprising airtight tank shell, swivel base, sealing
Flowing plate, sealing block, supporting plate, sealed silicon offset plate and Baltimore groove, swivel base is horizontally disposed, and sealing deflector is located at swivel base
Top, sealing deflector and swivel base be arranged in parallel, seal deflector and swivel base is bolted, sealing block
Side is fixed on airtight tank shell, and the opposite side of sealing block is provided with the groove being engaged with sealing deflector, sealed silicon offset plate
For tubular structure, sealed silicon offset plate is arranged vertically on swivel base, and swivel base is provided with what is be engaged with sealed silicon offset plate
Baltimore groove, the side of supporting plate are fixed on airtight tank shell, and the opposite side of supporting plate is fixedly connected with sealed silicon offset plate.
The sealing deflector is circular slab.
The sealing block is ring packing block, and the center line of the center line and sealing deflector of the groove on sealing block matches
Close.
The supporting plate is annular slab, and supporting plate is horizontally disposed.
The sealed silicon offset plate is the tubular structure being bolted by steel plate and high temperature resistant silicon offset plate.
The Baltimore groove is the loop configuration being engaged with sealed silicon offset plate, and Baltimore groove is fixed on swivel base.
Using the utility model, during work, airtight tank shell is fixed, and swivel base rotation, sealing block is fixed, and seals water conservancy diversion
Plate rotates, and forms I grade of sealing, the smelting smoke dust of entrance is obstructed, water conservancy diversion, reduces flue dust speed and inlet；Supporting plate
It is fixed, the rotation of sealed silicon offset plate, II grade of sealing is formed, a small amount of flue dust entered by I grade of sealing is sealed, prevents it from entering
Enter in airtight distributing box cavity.
The beneficial effects of the utility model are：I grade of sealing carries out barrier shunting to flue dust, reduces flue dust speed, II grade close
Secondary dust seal is carried out, airtight distributing box dust seal performance is lifted, can effectively avoid blast furnace staying caused by bad seals,
Good dustproof effect, extend the service life of airtight distributing box.
