Abstract

The utility model relates to an integral poured structure of a bracket, a circular beam and an inner ring of a circular air channel for a dry quenching furnace, which is characterized in that the integrally poured bracket, the integrally poured circular beam and the integrally poured inner ring of the circular air channel are arranged in a chute of the dry quenching furnace; a heat-resisting reinforcing steel bar and an anchoring piece are arranged in the integrally poured bracket; the integrally poured circular beam divides the integrally poured bracket into upper and lower parts; the integrally poured circular beam and the upper bracket form an integral structure; and the integrally poured inner ring of the circular air channel adopts a cylindrical structure. The integral poured structure of the integrally poured bracket, the circular beam and the inner ring of the circular air channel changes the structural form of the bracket and the circular beam, so that the integral poured structure is stressed more reasonably, the integrity of the inner ring is improved, the damage probability of the three parts is reduced, the service life is prolonged, and the times of annual repair are reduced.

Description

The integrated poured structure of ring in a kind of coke dry quenching furnace bracket, ring beam, the annular passage

Technical field

The utility model belongs to the integrated poured structure of a kind of coke dry quenching furnace part body of heater, the integrated poured structure of ring in particularly a kind of coke dry quenching furnace bracket, ring beam, the annular passage.

Background technology

At present; The domestic furnace binding of coke dry quenching furnace in the prior art is brickwork construction; Chute district bracket, ring beam are all built by laying bricks or stones by refractory brick and are formed, and exist: structural integrity is poor, and bracket receives ring beam and the long-pending shear stress that expands and produce of annular passage inner ring body under the condition of high temperature; Stress too concentrates on the preceding two row's bricks of bracket, causes the fracture of bracket brick, the problem that comes off can't solve all the time; Ring is brick cylindrical structure in the annular passage, and perforation appears in interior ring, phenomenon collapses; The maintenance way that adopts to the above-mentioned position of coke dry quenching furnace at brickwork construction is to change the damage brick or remove whole overhaul, and this maintenance way exists: problems such as complex process, materials planning cycle are long, and the construction period is long, difficulty is big, work-ing life is short.

Summary of the invention

The utility model has overcome defectives such as the brickwork construction globality of above-mentioned existence is poor, difficulty of construction is big, work-ing life is short; Purpose is to solve dry quenched coke oven chute district bracket brick and peels off damage, falls brick; The perforation of ring problem such as collapse provides the integrated poured structure of ring in a kind of coke dry quenching furnace bracket, ring beam, the annular passage in the annular passage.

The integrated poured structure content summary of ring in the utility model coke dry quenching furnace bracket, ring beam, the annular passage:

The integrated poured structure of ring in the utility model coke dry quenching furnace bracket, ring beam, the annular passage; It is characterized in that: in the dry quenched coke oven chute district is provided with integrated poured bracket, integrated poured ring beam and integrated poured annular passage, encircle, be provided with heat-resisting reinforcing bar and anchoring piece in the integrated poured bracket; Through integrated poured ring beam integrated poured bracket is divided into upper and lower two portions, integrated poured ring beam and top bracket are integral the formula structure; Ring adopts the cylindrical structure form in the integrated poured annular passage.

Encircle integrated poured structure in the utility model coke dry quenching furnace bracket, ring beam, the annular passage, changed the structure formation of bracket and ring beam, make more reasonable stress; Improved the globality of interior ring; Reduce the damage probability at above-mentioned three positions, prolonged work-ing life, reduced the annual overhaul number of times.

Description of drawings

Fig. 1 is the integrated poured structural representation of ring in coke dry quenching furnace bracket, ring beam, the annular passage

Fig. 2 is the integrated poured structure vertical view of coke dry quenching furnace ring beam

Among the figure: the 1st, integrated poured bracket, the 2nd, ring, the 4th in the integrated poured ring beam, the 3rd, integrated poured annular passage, heat-resisting reinforcing bar, the 5th, anchoring piece.

Embodiment

The integrated poured structure of ring is achieved in that to do below in conjunction with accompanying drawing and specifies in the utility model coke dry quenching furnace bracket, ring beam, annular passage.See Fig. 1, Fig. 2; The structure of bracket: the patented technology that adopts the applicant; Its patent No.: the special-purpose repair material of 20081017324.3 brackets; In the dry quenched coke oven chute district is provided with integrated poured bracket 1, integrated poured ring beam 2 and integrated poured annular passage, encircle 3, in integrated poured bracket 1, be provided with heat-resisting reinforcing bar 4 and carry out structure with anchoring piece 5 and strengthen, improve the globality of bracket; Improve the bonding strength of pour mass and residual bricking through anchoring piece 5 is installed, realize the whole stressed purpose of cast bracket.

Integrated poured ring beam 2 is divided into upper and lower two portions with integrated poured bracket 1, and integrated poured ring beam 2 is integral the formula structure with the top bracket.During operation the bottom bracket is poured into an integral body separately, last plane keeps level, smooth; Under the prerequisite that does not change the annular air channel breathing area; This structure has increased the stressed area of bracket; The stress that bracket is born is corresponding to be reduced, and the reactive force between bracket and the ring beam is main by shear-stress also, and changing into the stress is main strained condition; Reduced bracket is destroyed, prolonged the work-ing life of body of heater.

Ring 3 is cylindrical structures in the integrated poured annular passage, has changed prior art and has adopted brick adding to collude linguo-occlusal structural shape, influenced by working condition; The coke that internal reservoir is hot, temperature 950--1050 ℃, 4-6 meters of red Jiao's height; Inside receives Horizontal Tension, and the outside is the negative pressure and cavity environment, 2-4 meters of interior ring height; Have the eggshell effect, structural integrity is poor, the problem of structural integrity difference, has prolonged the work-ing life of interior ring.

Through heat-resisting reinforcing bar 4 is set, improved the overall construction intensity of pour mass.Heat-resisting reinforcing bar is smeared intergranular buffering stresscoat to the surface before use, and the expansion stress that the elimination metallic substance produces under the condition of high temperature is to the destruction of refractory materials; Heat-resisting reinforcing bar adopts corrugated form, eliminates the destruction of the linear expansion of heat-resisting reinforcing bar to material.

The integrated poured structure of ring in the utility model coke dry quenching furnace bracket, ring beam, the annular passage; Through improvement to coke dry quenching furnace bracket, ring beam, three positions of annular passage, changed the structure formation of bracket and ring beam, make more reasonable stress; Improved the globality of interior ring; Reduce the damage probability at above-mentioned three positions, prolonged work-ing life, reduced the annual overhaul number of times.
