Description

The combined refractory brick of coke dry quenching furnace annular passage chain structure
Technical field
The present invention relates to a kind of refractory brick, be specifically related to a kind of refractory brick that is used in the coke dry quenching furnace annular passage.
Background technology
Big event as the coking process energy-saving and emission-reduction---dry coke quenching is widespread use at home; Along with applying of homemade maximization dry coke quenching; Development of Dry Quenching Technology gradually becomes industrial hot spot with research; Especially to the dried breakage problem anxious to be solved especially of putting out anti-material in the stove in Dry Quenching Technology development and the practical application, the dry coke quenching body of heater is as the body section of dry coke quenching, and its importance is self-evident.But see safe operation that annular passage is damaged, the phenomenon of collapsing has seriously restricted dry coke quenching and usefulness performance from present domestic existing dry quenching system running condition.
The dried outside of putting out ring shape air channel does not contact with coke, but inboard must directly the contact with high temperature coke for a long time is prone to produce expanded by heating and wearing and tearing; And the outside is directly to contact with pump around circuit gas with the Cryogenic air that imports, and is easy to generate relative low temperature and shrinks, and it is inhomogeneous to be heated inside and outside the brick layer, causes the partition wall distortion.Coke all produces wall pressure to the inboard in the process of burnt whereabouts of dress and coke discharging descending motion; And partition wall is in the four direction of circumference; Left and right directions structurally is a fixed; So stove internal diameter direction enlargement deformation forwards, backwards occurs, be commonly called as " bulge ", thereby a large amount of longitudinal cracks appear in the top partition wall; Partition wall displacement occurs under the effect of coke external force, thereby has aggravated the damage of air flue partition wall.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of mosaic good in order to overcome deficiency of the prior art, is connected firmly, and long service life is difficult for the combined refractory brick of coke dry quenching furnace annular passage chain structure that caves in.
Technical scheme: in order to solve the problems of the technologies described above, the combined refractory brick of coke dry quenching furnace annular passage chain structure of the present invention, it comprises the brick body; Said brick body comprises joint face, following joint face, left joint face, right joint face, preceding joint face and back joint face; Said go up joint face with following joint face be about the joint face of two brick bodies, said left joint face, right joint face be about the joint face of two brick bodies, be provided with little groove on the joint face on said; Be provided with little tenon on the joint face down said; Said little groove and little tenon coupling are chimeric, on said left joint face, are provided with big groove, on said right joint face, are provided with big tenon; Said big groove is chimeric with big tenon coupling, and the width of said preceding joint face is littler than the width of back joint face.
Said brick body is the mullite brick body.
The interconnection formation cylindrical shell of said brick body.
On the joint face of said back, be provided with the heat-resistance stainless steel groove; In said heat-resistance stainless steel groove, be provided with the heat-resistance stainless steel muscle; Said heat-resistance stainless steel muscle is fixed in the said heat-resistance stainless steel groove through the high temperature steel web member, and the junction of said heat-resistance stainless steel muscle is tied up fixing with iron wire.
In said heat-resistance stainless steel groove, inject high-strength phosphagel phosphaljel ramming mass, said high-strength phosphagel phosphaljel ramming mass combines name with wedding agent and its constructional method, and wherein wedding agent is a phosphagel phosphaljel, and constructional method is a ramming process.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: the present invention makes the brick body connect robust each other, long service life at last joint face, down be provided with groove or tenon on joint face, left joint face and the right joint face.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6; The combined refractory brick of coke dry quenching furnace annular passage chain structure of the present invention belongs to the refractory brick field, and it comprises brick body 1, and said brick body 1 comprises joint face 2, following joint face 3, left joint face 4, right joint face 5, preceding joint face 6 and back joint face 7; Said go up joint face 2 with following joint face 3 be about the joint face of two brick bodies; Said left joint face 4, right joint face 5 be about the joint face of two brick bodies, be provided with little groove 8 on the joint face 2 on said, be provided with little tenon 9 on the joint face 3 down said; Said little groove 8 is chimeric with little tenon 9 couplings; On said left joint face 4, be provided with big groove 10, on said right joint face 5, be provided with big tenon 11, said big groove 10 is chimeric with big tenon 11 couplings; Little groove tenon on the joint face can effectively prevent brick body 1 because the influence of the wall pressure that coke falls to producing up and down; Two brick bodies connected more firmly about the big groove tenon of left and right sides joint face made, phenomenon can not occur throwing off because of former little groove tenon, said before the width of joint face 6 littler than the width of back joint face 7; Said brick body 1 is a mullite silicon carbide brick body; Said brick body 1 interconnection formation cylindrical shell; On the joint face 7 of said back, be provided with heat-resistance stainless steel groove 12; In said heat-resistance stainless steel groove 12, being provided with diameter is the heat-resistance stainless steel muscle 13 of 6mm; Said heat-resistance stainless steel muscle 13 is fixed in the said heat-resistance stainless steel groove 12 through high temperature steel web member 14, and the junction of said heat-resistance stainless steel muscle 13 is tied up fixing with iron wire 15; In said heat-resistance stainless steel groove 12, inject high-strength ramming mass 16, through on the joint face 7 of back, heat-resistance stainless steel groove 12 being set, and be provided with heat-resistance stainless steel muscle 13 and high-strength phosphagel phosphaljel ramming mass 16 at heat-resistance stainless steel groove 12; Make that the whole connection of brick body is more firm, in the past because the brick body was in the wall pressure of coke, the environment of the exchange of expanded by heating and freezing air for a long time; Be easy to landslide or damage, adopt heat-resistance stainless steel muscle 13 to encircle connection, eliminated above-mentioned influence; Improved work-ing life greatly; Life cycle generally can reach more than 8 years, between said up and down brick body, also left the gap, and the refractory mortar etc. that is used to fill equal material is built the connection material by laying bricks or stones; Make bulk strength be further enhanced, the brick body that joint face after is provided with heat-resistance stainless steel groove 12 is set in the per 5 layers of brick layer of vertical direction.Mosaic of the present invention is good, is connected firmly, and long service life is difficult for landslide.
The present invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
