Description
Technical field
The present invention relates to a kind of blast furnace top fire hole sealing devices, belong to blast furnace in metallurgical industry production equipment technology neck
Domain.
Background technology
Blast furnace top fire hole needs to open after each damping down, after coal gas in stove is lighted, observes stove internal protecting wall knot shape thickness
State measures stock rod zero-bit, judges chute abrasion condition etc..After furnace compound wind, it is wrapped in a little after usually soaking bath of glass with asbestos cord
On fire hole, then will igniting port lid pressure closing.This sealing structure has the following problems：
（1）Fire hole closing is manually wound in fire hole using asbestos cord leaching bath of glass, uneven due to winding, after furnace compound wind
Occur poorly sealed, gas leak phenomenon repeatedly, leads to the secondary damping down of blast furnace；
（2）Due to top temperature height, bath of glass solidification, lower sealing surface increases, more difficult when seal point fire hole again, easily occurs
Poorly sealed phenomenon, and result in waste of resources.
Invention content
It is an object of the present invention to provide a kind of blast furnace top fire hole sealing devices, and sealing effect is good, can avoid the occurrence of coal
Gas leakage phenomenon, solves the problems, such as background technology.
The technical scheme is that：
A kind of blast furnace top fire hole sealing device, including cranking arm, groove, igniting port lid, fastening axis pin, pressing plate and temperature-resistant graphite
Packing, is equipped with igniting port lid on blast furnace top fire hole, and one end of the igniting port lid is fixed on blast furnace by cranking arm
On, the other end for port lid of lighting a fire is equipped with a block pressur plate, and pressing plate is fixed on fastening axis pin, and fastening axis pin is fixed on blast furnace
On, fire hole is covered is equipped with multiple tracks groove around furnace roof fire hole, and temperature-resistant graphite packing is filled in the groove.
It is twice that the fire hole, which covers the groove on furnace roof fire hole, and groove is semi-circular groove.
Described to crank arm as L-type, that cranks arm is fixed on by axis pin on blast furnace on one side, and the another side cranked arm is pressed on a little
On fire hole cover.
It is described to crank arm equipped with the strip hole coordinated with axis pin.
Above-mentioned blast furnace top fire hole sealing device, is fixed with igniting hole seat on the inner wall of blast furnace top fire hole.
The beneficial effects of the invention are as follows：Replace disposable asbestos cord as sealing material using temperature-resistant graphite packing
Material can improve sealing effect, reduce the wasting of resources, avoid gas leakage, ensure that safety in production.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
In figure：Crank arm 1, groove 2, igniting port lid 3, igniting hole seat 4, fastening axis pin 5, pressing plate 6, axis pin 7.
Specific implementation mode
Below in conjunction with attached drawing, by example, the invention will be further described.
With reference to attached drawing 1, a kind of blast furnace top fire hole sealing device, including 1, groove 2 of cranking arm, igniting port lid 3, holding pin
Axis 5, pressing plate 6 and temperature-resistant graphite packing, are equipped with igniting port lid 3 on blast furnace top fire hole, and one end of the igniting port lid 3 is logical
It crosses to crank arm and 1 be fixed on blast furnace, the other end of igniting port lid 3 is equipped with a block pressur plate 6, and pressing plate 6 is fixed on fastening axis pin 5
On, fastening axis pin 5 is fixed on blast furnace, and multiple tracks groove 2, the groove 2 are equipped with around furnace roof fire hole on port lid 3 of lighting a fire
It is interior to be filled with temperature-resistant graphite packing.
In the present embodiment, the groove 2 on igniting port lid 3 on furnace roof fire hole is twice, and groove 2 is semicircle
Slot, sectional dimension are：12mm × 7mm, and temperature-resistant graphite packing is filled in groove 2, the sectional dimension of temperature-resistant graphite packing is
12mm×12mm。
It 1 is L-type to crank arm, and cranking arm 1 is on one side fixed on by axis pin 7 on blast furnace, and 1 another side of cranking arm is pressed on a little
On fire hole cover 3,1 is cranked arm equipped with the strip hole coordinated with axis pin 7, the fixed position of axis pin 7 can be adjusted by strip hole.
Using the present invention, blast furnace top fire hole has used 5 years, gas leakage never occurs, only needs replace one within every six months
Secondary temperature-resistant graphite packing, significant effect.
