Abstract
The utility model provides a blast furnace stock rod overhauls uses novel sealing door, includes access door, access door seat, slot, silica gel stick, high strength bolt, on the access door seat, is equipped with the round around the access hole and becomes to seal rectangular slot, and the depressed part of slot is semi-circular, and the silica gel stick is placed at the ditch inslot, and the access door is detained on the silica gel stick, and the access door is fixed on the access door seat with high strength bolt. Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a blast furnace stock rod overhauls uses novel sealing door, is through changing the sealed mode and the sealing material of high furnace stock rod access door, has not only guaranteed the sealed effect of access door, has prolonged the life of sealing member, makes the operation process of changing the stock rod stone roller convenient and fast more moreover, has reduced intensity of labour, has shortened the activity duration, has reduced operation personnel's accident risk, has practiced thrift cost of maintenance simultaneously, has created certain benefit for the enterprise.
Description
Technical field
The utility model relates to a kind of blast furnace probing rod maintenance Novel sealing door.
Background technology
Modernization blast furnace in metallurgical industry is smelted, and needs prolonging campaign, low consumption, high yield, and how blast-furnace equipment adapts to the use properties that high strength is produced, reduce the repair time, reduce maintenance cost, save the consumption of spare unit part, guaranteeing personal safety is guarantee the stable prerequisite smoothly of blast furnace.
Existing ironmaking head factory, every blast furnace roof is provided with 3 stock rod casees, stock rod stone roller is installed in stock rod case, for detecting charge level situation in stove, stock rod equipment need be operated at full capacity every day, and stock rod stone roller is in high temperature for a long time, run under dust atmosphere, stock rod stone roller scaling loss, come off, connection steel cable blows phenomenon and again and again occurs, conveniently overhaul, design and installation access door on the stock rod casing, the seal form adopted is the bolt column of maintenance gate seat plane pre-installation 20 M24, access door is connected fastening by bolt column with gate seat, viton plate is adopted to seal between access door and gate seat.But because viton sealing plate is in the environment of high temperature, high pressure, steam for a long time, the very easily damaged corrosion of viton, sealing property lost efficacy, and caused stock rod door to reveal, and impact is normally produced.And, change stock rod stone roller each, when opening access door, viton plate also all can damaged, lost efficacy, must while the rubber plate that more renew.So, replacing stock rod stone roller and stock rod door sealing plate just become the common events in operation of maintenance repair, change sealing plate to need on sealing plate, first make a call to 20 holes, pitch-row will match with the pitch-row on maintenance gate seat, then seal gum is smeared, last fastening stock rod door, its operational procedure is loaded down with trivial details, activity duration is longer, and stock rod case region is due near furnace body, the coal gas that blast furnace stack is revealed and the coal gas that stock rod door is revealed make this region gas content often exceed standard, long-time operation herein very easily causes operating personnel colony gas poisoning, serious threat staff life security, serious restriction blast furnace is produced smoothly.Often change the consumption that viton sealing plate also result in a large amount of spare parts simultaneously, add maintenance cost.
Summary of the invention
The utility model provides a kind of blast furnace probing rod maintenance Novel sealing door, by changing sealing means and the sealing material of blast furnace probing rod access door, not only ensure that the sealing effectiveness of access door, extend the work-ing life of sealing member, and make the operating process changing stock rod stone roller more convenient, decrease labour intensity, shorten the activity duration, reduce the accident risk of operating personnel, saved maintenance cost simultaneously, for enterprise creates certain benefit.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of blast furnace probing rod maintenance Novel sealing door, comprise access door, maintenance gate seat, groove, silica gel stick, high-strength bolt, on maintenance gate seat, the surrounding of access hole is provided with one and encloses into closed rectangular groove, the sunk part of groove is semicircle, silica gel stick is placed in groove, and access door is buckled on silica gel stick, and access door high-strength bolt is fixed on maintenance gate seat.
Compared with prior art, the beneficial effects of the utility model are:
A kind of blast furnace probing rod maintenance Novel sealing door, by changing sealing means and the sealing material of blast furnace probing rod access door, not only ensure that the sealing effectiveness of access door, extend the work-ing life of sealing member, and make the operating process changing stock rod stone roller more convenient, decrease labour intensity, shorten the activity duration, reduce the accident risk of operating personnel, saved maintenance cost simultaneously, for enterprise creates certain benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of blast furnace probing rod maintenance of the utility model Novel sealing door.
In figure: 1. access door .2. overhauls gate seat .3. groove .4. silica gel stick .5. high-strength bolt 6. stock rod case 7. access hole
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
As shown in the figure, a kind of blast furnace probing rod maintenance Novel sealing door, comprise access door 1, maintenance gate seat 2, groove 3, silica gel stick 4, high-strength bolt 5, on maintenance gate seat 2, the surrounding of access hole 7 is provided with one and encloses into closed rectangular groove 3, and the sunk part of groove 3 is semicircle, and silica gel stick 4 is placed in groove 3, access door 1 is buckled on silica gel stick 4, and access door 1 high-strength bolt 5 is fixed on maintenance gate seat 2.
Silica gel stick 4 corrosion resistance nature is high, resistance to elevated temperatures is good, high temperature resistant degree can reach 250 DEG C, there is good elasticity simultaneously, so its work-ing life is longer, need not frequently change, when changing stock rod stone roller, check that silica gel stick is not under having wound to collide with and ensureing enough elastic situation, do not need each replacing, even if need replacement operation mode very simple yet.
During use: first high-strength bolt 5 is screwed dismounting, take off access door 1, replacing stock rod is cut or polish jade with an emery wheel, check whether silica gel stick 4 has wound to collide with, whether keep elasticity, as silica gel stick 4 can continue to use, then access door 1 is buckled, be fixed on maintenance gate seat 2 by high-strength bolt 5, access hole 7 is sealed up.As found, silica gel stick 4 needs to change, and changes new, then access hole 7 to be closed with access door 1 and go up as long as taken off by former silica gel stick 4.
Claims (1)
1. a blast furnace probing rod maintenance Novel sealing door, it is characterized in that, comprise access door, maintenance gate seat, groove, silica gel stick, high-strength bolt, on maintenance gate seat, the surrounding of access hole is provided with one and encloses into closed rectangular groove, and the sunk part of groove is semicircle, and silica gel stick is placed in groove, access door is buckled on silica gel stick, and access door high-strength bolt is fixed on maintenance gate seat.
