The purpose of this utility model is to overcome above-mentioned weak point, thus a kind of air-cooled quenching furnance supporting roll is provided, its structure design is simple, compact, reasonable, air cooling way is adopted to be cooled in time by supporting roll, avoid supporting roll to be in for a long time under worst hot case to damage, available protecting supporting roll; But also the structural strength of supporting roll can be improved, improve the work-ing life of supporting roll, reduce maintenance of equipment maintenance cost.
Technical scheme according to the utility model provides: air-cooled quenching furnance supporting roll, comprise main roll body, described main roll body two ends are welding transition connection roll respectively, described transition connection roll outer end welding spindle nose, be provided with lagging material packing layer in transition connection roll, described lagging material packing layer is encapsulated by baffle plate; It is characterized in that: described main roll body is hollow structure, is provided with ventilation hole in described spindle nose, the ventilation hole outer end on one of them spindle nose is provided with the swivel joint for connecting high-pressure air; Be provided with transition air channel in described lagging material packing layer and baffle plate, described transition air channel is connected with the ventilation hole the inner on corresponding end spindle nose, and the ventilating hole channel outer end on one of them spindle nose is provided with the swivel joint for connecting high-pressure air.
As further improvement of the utility model, spiral plate is provided with in described main roll body, the neighboring of described spiral plate is along being welded and fixed with main roll body inwall, and form volution air channel between described spiral plate and main roll body, two ends, described volution air channel are communicated with the transition air channel at two ends respectively.
As further improvement of the utility model, described transition connection roll is cone, and the stub end of transition connection roll connects main roll body, the little head end coupling shaft head of transition connection roll.
compared with the prior art the utility model, has the following advantages:
The utility model structure design is simple, compact, reasonable, adopts air cooling way to be cooled in time by supporting roll, avoids supporting roll to be in for a long time under worst hot case and damage, available protecting supporting roll; But also the structural strength of supporting roll can be improved, improve the work-ing life of supporting roll, reduce maintenance of equipment maintenance cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is further described.
As shown in Figure 1, the air-cooled quenching furnance supporting roll in embodiment is primarily of compositions such as main roll body 1, transition connection roll 2, lagging material packing layer 3, spindle nose 4, swivel joint 5, spiral plate 6 and baffle plates 7.
As shown in Figure 1; described main roll body 1 two ends are welding transition connection roll 2 respectively; described transition connection roll 2 outer end welding spindle nose 4; lagging material packing layer 3 is provided with in transition connection roll 2; described lagging material packing layer 3 is encapsulated by baffle plate 7; lagging material packing layer 3 is used for protecting supporting roll, avoids its temperature rise too fast.
As shown in Figure 1, described main roll body 1 is hollow structure, is provided with ventilation hole 4a in described spindle nose 4, and the ventilation hole 4a outer end on one of them spindle nose 4 is provided with the swivel joint 5 for connecting high-pressure air; Be provided with transition air channel 3a in described lagging material packing layer 3 and baffle plate 7, described transition air channel 3a is connected with the ventilation hole 4a the inner on corresponding end spindle nose 4, and the outer end, ventilation hole 4a road on one of them spindle nose 4 is provided with the swivel joint 5 for connecting high-pressure air.
As shown in Figure 1, spiral plate 6 is provided with in described main roll body 1, the neighboring of described spiral plate 6 is along being welded and fixed with main roll body 1 inwall, and form volution air channel between described spiral plate 6 and main roll body 1, two ends, described volution air channel are communicated with the transition air channel 3a at two ends respectively.
As shown in Figure 1, in the utility model embodiment, described transition connection roll 2 is cone, and the stub end of transition connection roll 2 connects main roll body 1, the little head end coupling shaft head 4 of transition connection roll 2.
During work, by swivel joint 5 to supporting roll inner ventilation, heat can be taken away rapidly, avoid supporting roll temperature rise too high, protection supporting roll.Spiral plate 6 simultaneously can improve the structural strength of main roll body 1.
