Ringwall bulge control device in coke dry quenching furnace
Technical field
The utility model relates to coke dry quenching furnace field, specifically refers to ringwall bulge control device in a kind of coke dry quenching furnace.
Background technology
Coke dry quenching furnace is a kind of environment-protecting industrial stove reclaiming red burnt sensible heat, produce steam or generating, and its shell is cast iron, and interior wall forms with the laying fireproof bricks of different size.Coke dry quenching furnace outer ring wall is positioned at bracket top, until fire door position.Leave annular passage between ringwall in coke dry quenching furnace outer ring wall and coke dry quenching furnace, pass through for the high-temp waste gas absorbed after red burnt sensible heat.
In coke dry quenching furnace, ringwall in process of production, constantly washing away and corroding due to high-temp waste gas, is easy to produce outside bulging force, forms bulge.Designing unit, when the coke dry quenching furnace initial stage is designed, does not take into full account this part stress, and thus internally ringwall does not carry out corresponding bulge protection.In the coke dry quenching furnace of current shutdown maintenance, the interior ringwall of most of stove all has bulge in various degree, cracking phenomena.The coke dry quenching furnace even had, because interior ringwall bulge is collapsed and is forced to shutdown maintenance, has a strong impact on the normal production of coke dry quenching furnace and blast furnace.
At present, for the phenomenon not good terms of settlement of ringwall bulge in coke dry quenching furnace, only have and adopt blowing out to change brick and blowing out to repair damaged resistance to material two kinds of modes and keep in repair.
Summary of the invention
The purpose of this utility model provides ringwall bulge control device in a kind of coke dry quenching furnace according to above-mentioned deficiency, and this device not only can prevent the formation of ringwall bulge in coke dry quenching furnace, and can prevent the further deterioration of ringwall bulge in coke dry quenching furnace.
The technical solution of the utility model is as follows: ringwall bulge control device in a kind of coke dry quenching furnace, in coke dry quenching furnace above coke dry quenching furnace bracket partition wall between ringwall and coke dry quenching furnace outer ring wall, it is characterized in that: it comprise be arranged on interior wall protective bulkhead in coke dry quenching furnace outside ringwall, supporting beam that two ends connect interior wall protective bulkhead and coke dry quenching furnace outer ring wall respectively; Wherein, be fixedly connected with between supporting beam with interior wall protective bulkhead, and be slidably connected between coke dry quenching furnace outer ring wall.
Further, described supporting beam is three, and one end that they are connected with interior wall protective bulkhead is uniformly distributed three tie points from top to bottom, and the one end be connected with coke dry quenching furnace outer ring wall is intersected in a tie point.
Further, described three supporting beams are upper Steel Reinforcement Cage, middle Steel Reinforcement Cage and descending reinforcing cage.
Further, described coke dry quenching furnace outer ring wall is provided with sliding connector, described sliding connector comprises three expansion bolts be fixedly plugged on coke dry quenching furnace outer ring wall, three expansion bolt afterbodys are respectively welded with butterfly nail, three butterfly nails are inserted in overlap movable with it in Steel Reinforcement Cage, middle Steel Reinforcement Cage and one end of descending reinforcing cage respectively and are connected, be cast with refractory materials in described upper Steel Reinforcement Cage, middle Steel Reinforcement Cage and descending reinforcing cage, described refractory materials and butterfly leave hollow gap between following closely.
Further, to be that refractory materials is fixing pour into a mould structure in one end that described upper Steel Reinforcement Cage, middle Steel Reinforcement Cage and descending reinforcing cage are connected with interior wall protective bulkhead.
The utility model is reinforced bulge position on ringwall in coke dry quenching furnace by arranging supporting beam, and prevents the further deterioration of bulge position, and avoid it in high-temp waste gas, continue bulge and collapse, that causes coke dry quenching furnace is forced to blowing out.And by arranging interior wall protective bulkhead, expand the thrust surface of bulge position.Supporting beam and coke dry quenching furnace outer ring wall are slidably connected and the stress that in coke dry quenching furnace, on ringwall, bulge place produces can be avoided to cause secondary injury by internal ringwall in addition, form stress damage.Preferably arranging three supporting beams can make the utility model structure more firm, stressed more balanced.The utility model structure is simple, and effect is good, and cost is low, has very strong practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model supporting beam and coke dry quenching furnace outer ring wall are slidably connected the structural representation of mechanism;
Ringwall in Steel Reinforcement Cage, 5-descending reinforcing cage, 6-interior wall protective bulkhead, 7-coke dry quenching furnace, 8-expansion bolt, 9-butterfly nail, 10-sliding connector in 1-bracket partition wall, 2-coke dry quenching furnace outer ring wall, the upper Steel Reinforcement Cage of 3-, 4-.
Embodiment
The present invention is further illustrated by specific embodiment below in conjunction with accompanying drawing:
As shown in Figure 1; coke dry quenching furnace outer ring wall 2 is positioned at bracket partition wall 1 top; in control coke dry quenching furnace of the present utility model, the device of ringwall bulge between ringwall 7 and coke dry quenching furnace outer ring wall 2, comprises the Steel Reinforcement Cage that interior wall protective bulkhead 6, three two ends be arranged in coke dry quenching furnace outside ringwall 7 connect interior wall protective bulkhead 6 and coke dry quenching furnace outer ring wall 2 respectively in coke dry quenching furnace.From top to bottom, one end that upper Steel Reinforcement Cage 3, middle Steel Reinforcement Cage 4 and descending reinforcing cage 5 are connected with interior wall protective bulkhead 6 is uniformly distributed three tie points from top to bottom, is connected one end is intersected in a tie point with coke dry quenching furnace outer ring wall 2.Wherein, be fixedly connected with by casting refractory between Steel Reinforcement Cage with interior wall protective bulkhead 6, and be slidably connected by sliding connector 10 between coke dry quenching furnace outer ring wall 2.
Described sliding connector 10 structural representation as shown in Figure 2, described sliding connector 10 comprises three expansion bolts 8 be fixedly plugged on coke dry quenching furnace outer ring wall 2, three expansion bolt 8 afterbodys are respectively welded with butterfly nail 9, three butterflies nails 9 and are inserted in respectively Steel Reinforcement Cage 3, middle Steel Reinforcement Cage 4 and one end of descending reinforcing cage 5 in overlap with its activity and are connected.Be cast with refractory materials in described upper Steel Reinforcement Cage 3, middle Steel Reinforcement Cage 4 and descending reinforcing cage 5, described refractory materials and butterfly leave hollow gap between following closely 9, make Steel Reinforcement Cage can slide into Steel Reinforcement Cage within the specific limits and prop up coke dry quenching furnace outer ring wall position.Avoid the stress that in coke dry quenching furnace, on ringwall, bulge place produces can cause secondary injury to ringwall in coke dry quenching furnace, form stress damage.
Concrete installation steps of the present utility model are:
