In the prior art, a comparison document 2018, 3, 9 and discloses a large-diameter closed flat furnace cover of an ore furnace, which is named as 'a large-diameter closed flat furnace cover of an ore furnace', and has patent numbers: 201721177412.8. the structure of the furnace comprises a tower-shaped hanging steel framework connected with the edge of a furnace shell, a flat furnace plate is hung below the tower-shaped hanging steel framework, and the middle of the flat furnace plate is connected with a central cover plate; the tower-shaped hanging steel framework comprises an inner ring steel beam and an outer ring steel beam, a plurality of steel beams are connected between the inner ring steel beam and the outer ring steel beam at intervals along the circumference, the inner end of each steel beam is connected with the inner ring steel beam, and the outer end of each steel beam is connected with the furnace shell; the steel beams are obliquely arranged, the axis of each steel beam forms an included angle of 4-6 degrees with the horizontal plane, and the steel beams, the inner ring steel beams and the outer ring steel beams form an integral arch structure, so that the strength and the rigidity of the tower-type hanging steel framework are improved; each steel beam is connected with the open hearth plate in an insulating and hanging manner. The blanking pipe is provided with a plurality of parts along the circumference and is communicated and connected with the furnace cover body. The furnace has the disadvantages that the blanking pipe and the furnace cover are sealed by refractory bricks, the sealing performance is poor, the dust raising is large, the environment is greatly polluted, the air outside the equipment enters the area to generate high temperature, and numerous potential safety hazards are brought to the equipment and operators.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide the flat furnace cover with the steel framework of the submerged arc furnace, which has a simple structure and is reliable in sealing.
The technical solution of the utility model is as follows: the submerged arc furnace steel skeleton flat furnace cover comprises a plurality of blanking pipes which are uniformly distributed along the circumference, and the blanking pipes are communicated and connected with the inside of the furnace cover body; the lower section of the blanking pipe is a section of lower circular pipe, the upper end of the lower circular pipe is externally connected with an upper disc, and the periphery of the upper disc is provided with an upper convex edge.
In the above scheme, the method further comprises:
ceramic fiber insulating sealing materials are pressed between the disc at the upper section of the blanking pipe and the upper disc at the lower section of the blanking pipe.
The rib plate is in a ring shape.
The diameter of the round pipe at the upper section of the blanking pipe is smaller than that of the round pipe at the lower section of the blanking pipe.
The upper disc is paved with a fine sand layer.
The utility model has the advantages that: 1. the sealing part between the two sections of the blanking pipe is reasonable in design, simple in structure and reliable in sealing. 2. The feeding section of the blanking pipe is made of high-temperature-resistant ceramic fiber materials as insulating parts, so that the sealing effect is better.

Detailed Description
Referring to fig. 1-3, the part names are as follows: the furnace comprises a discharging pipe 1, a furnace cover 2, a circular pipe 3, a disc 4, an insulating sealing material 5, a rib plate 6, a material 7, a lower circular pipe 8, an upper disc 9, an edge 10, a fine sand layer 11, a furnace body 12, a main beam 13, a short auxiliary beam 14, a long auxiliary beam 15, a chimney hole 16 and a central cover plate 17.
Referring to fig. 1-3, the steel skeleton flat furnace cover of the submerged arc furnace comprises a plurality of blanking pipes 1 which are uniformly arranged along the circumference. The blanking pipe 1 is communicated and connected with the interior of the furnace cover 2 and is led into the furnace body 12. The blanking pipe 1 is formed by insulating, sealing and buckling the upper section of the blanking pipe and the lower section of the blanking pipe. The lower section of the blanking pipe is inserted into the furnace body 12. The upper section of the blanking pipe is a section of circular pipe 3, the lower end of the circular pipe 3 is externally connected with a disc 4, and a convex annular rib plate 6 inserted into the insulating sealing material 5 is arranged below the disc 4, so that the effect of fixing the insulating sealing material 5 is better. The lower section of the blanking pipe is a section of lower circular pipe 8, the upper end of the lower circular pipe 8 is externally connected with an upper disc 9, and the periphery of the upper disc 9 is provided with an upper convex edge 10 for fixing the insulating sealing material 5, so that the effect is better. Go up disc 9 upper berth and have fine sand layer 11 (avoid electrically conductive easily, have creepage distance when the electric current is too big), play insulating effect, sealed effectual, no smoke and dust avoids high temperature to bring equipment and operating personnel's potential safety hazard. Ceramic fiber insulating sealing materials 5 are pressed between the disc 4 at the upper section of the blanking pipe and the upper disc 9 at the lower section of the blanking pipe. The diameter of the round tube 3 at the upper section of the blanking tube is smaller than that of the round tube 8 at the lower section of the blanking tube, so that the feeding is smooth.
The foregoing description is only exemplary of the utility model and is not intended to limit the spirit of the utility model.
