Mutual bolt connection, the bolt connection of going to the bottom of the upper bottom of trapezoidal furnace sidewall and corresponding trapezoidal furnace top cover per block；The trapezoidal stove per block
The upper bottom of side wall arranges the first mounting ear of level, per block trapezoidal furnace top cover go to the bottom setting level and extended line with furnace top cover is in
Second mounting ear of acute angle, the first mounting ear and the second mounting ear are bolted to connection so that central lid is installed than first
The horizontal level of ear is high 100 millimeters.
Preferably, arranging insulating barrier between the first mounting ear and the second mounting ear.
Preferably, the mutually bolted waist of every piece of adjacent trapezoidal furnace top cover installs 2 hangings, every piece of furnace top cover and center
1 hanging is installed at the mutually bolted upper bottom of lid.
Preferably, arranging Explosion-proof cap, dodge gate, the installing hole of electrode column, and feed opening, installing hole and feed opening are set
Back-up ring is all set.
The utility model beneficial effect includes：Furnace cover structure after improvement, increases the support force of bell, effectively prevents stove
Cover because long term high temperature environment using when the sagging deformation for causing.Bell support strength can reduce bell hanging quantity after increasing,
Cost-effective.Prevent when bell deforms, the unbalance stress in bell face, local pressure is excessive to cause sheet material cracking or weak spot
Weld cracking, increases the service life.After three-phase electricity pole is firm, reduce because the blowing out that electrode deflection causes is examined in smelting process
Repair.

Fig. 2 is the overlooking the structure diagram of the domatic arch mineral hot furnace bell in the utility model embodiment；
Fig. 3 is the mplifying structure schematic diagram of location A in Fig. 1.
Specific embodiment
Bell bearing strength be improved in order to provide, extend bell service life, reduce and deform, because of bell, the stove for causing that subsides
Lid cracking, electrode column deflection cause three-phase electricity pole unbalanced, it is to avoid ponding pours in down a chimney the realization side for causing security incident to burner hearth
Case, the utility model embodiment provide a kind of domatic arch mineral hot furnace bell, new to this practicality below in conjunction with Figure of description
The preferred embodiment of type is illustrated.
Refering to shown in Fig. 1, Fig. 2 and Fig. 3, a kind of domatic arch mineral hot furnace bell, including：6 pieces of furnace top covers, 1,6 pieces of furnace sidewall
22 and central lid constitute the polygon stage body for going to the bottom open；Wherein, the mutual bolt of the waist of every piece of adjacent trapezoidal furnace top cover 1 connects
Connect, per block the upper bottom of trapezoidal furnace top cover 1 all with central lid bolt connection, be spliced into circular stove top case；Every piece of adjacent trapezoidal furnace side
The mutual bolt connection of the waist of wall 2, the bolt connection of going to the bottom of the upper bottom of trapezoidal furnace sidewall 2 and corresponding trapezoidal furnace top cover 1 per block；Per
The upper bottom of the trapezoidal furnace sidewall 2 of block arranges the first mounting ear of level, go to the bottom setting level and the extended line of trapezoidal furnace top cover 1 per block
Second mounting ear at an acute angle with furnace top cover 1, the first mounting ear 11 and the second mounting ear 22 are bolted to connection so that in
Heart lid is higher than the horizontal level of the first mounting ear 100 millimeters.
Wherein, insulating barrier is set between the first mounting ear 11 and the second mounting ear 22.Every piece of adjacent trapezoidal furnace top cover 1 is mutual
Bolted waist installs 2 hangings, and every piece of furnace top cover 1 installs 1 hanging with the mutually bolted upper bottom of central lid.Bell
