Description
Technical field
The utility model relates to gypsum board production line equipment, specifically the isobaric bellows of a kind of large-scale hot-blast stove with reinforcement compound insulation structure.
Background technology
The equal wind effect of design relation coal combustion layer of the isobaric bellows of Coal-fired Fluidized Bed Hot Air Furnace.If it is improper to design, bellows top cloth wind can be caused uneven, a stove difficulty can be caused time serious, or operation control improper time frequent coking, the bellows volume of large-scale Coal-fired Fluidized Bed Hot Air Furnace more than 30 cubic metres, general bellows steel plate thickness δ 7-10mm, material bed and blast pressure overlaying influence is subject to during operation, bellows intensity is not enough to form surging, causes serious material bed and the vibration of bellows turbulent flow, affects hot-blast stove and normally run.
Summary of the invention
For solving the technical problem of above-mentioned existence, the utility model provides the isobaric bellows of a kind of large-scale hot-blast stove with reinforcement compound insulation structure, improves bellows overall construction intensity, reduces noise, significantly reduce bellows radiation loss.
For achieving the above object, the technical scheme that the utility model adopts is:
The isobaric bellows of a kind of large-scale hot-blast stove with reinforcement compound insulation structure, include bellows main body, in described bellows main body, some slag-discharge pipes are set, protrude from bellows bottom part body bottom described slag-discharge pipe and be provided with slagging flashboard, described bellows bottom part body is provided with access door, the shell steel plate outer surface of described bellows main body arranges reinforcement layer and heat-insulation layer composite construction, described reinforcement layer is made up of some reinforcement gussets anyhow arranged in a crossed manner, covers compression color steel plate and form outside after described heat-insulation layer is arranged by the rock wool-steel plywood fissure of displacement.
Described reinforcement gusset is set to width 25-80mm, the strip-shaped steel plate of thickness δ 7-12mm.
Described rock wool-steel plywood is set to the lateral surface that the two-layer fissure of displacement is respectively arranged in bellows main body.
It is outer and be set to two joints that described slag-discharge pipe top protrudes from bellows body top air distribution plate, bottom protrudes from bellows main body base plate.
The utility model devises reinforcing rib structure outside the steel plate of traditional bellows, add the structural strength of bellows main body, add the heat-insulation layer of rock wool-steel plywood fissure of displacement splicing composition in the periphery of reinforcement and cover compression color steel plate outward, the radiation loss of remarkable minimizing bellows, bottom slag-discharge pipe, outstanding bellows main body base plate two saves, and give prominence to air distribution plate at slag-discharge pipe top, air distribution plate equal wind better effects if during operation, the coal seam of top fluidized state can keep fluidisation even for a long time, slag-discharge pipe can in conjunction with the effective deslagging of combustion conditions, avoid the formation of the inclined bed of coal combustion layer and putty, be applicable to the isobaric bellows of large-scale hot-blast stove adapted, also conventional type of furnace bellows are applicable to, make hot-blast stove even running, reduce operating cost, increase economic efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is lateral plan of the present utility model.。
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown in Figure 1-2, the isobaric bellows of large-scale hot-blast stove of this band reinforcement compound insulation structure, include bellows main body 3, described bellows main body, some slag-discharge pipes 2 are set in 3, to protrude from bottom described slag-discharge pipe 2 bottom bellows main body 3 and to be provided with slagging flashboard 7, access door 8 is provided with bottom described bellows main body 3, shell steel plate 5 outer surface of described bellows main body 3 arranges reinforcement layer and heat-insulation layer composite construction, described reinforcement layer is made up of some reinforcement gussets 4 anyhow arranged in a crossed manner, cover compression color steel plate 6 outside after described heat-insulation layer is arranged by rock wool-steel plywood 5 fissure of displacement to form.
As preferred mode, described reinforcement gusset 4 is set to width 25-80mm, the strip-shaped steel plate of thickness δ 7-12mm.
As preferred mode, described rock wool-steel plywood 5 is set to the lateral surface that the two-layer fissure of displacement is respectively arranged in bellows main body 3.
As preferred mode, it is outer and be set to two joints that described slag-discharge pipe 2 top protrudes from bellows main body 3 top air distribution plate 1, bottom protrudes from bellows main body 3 base plate.
In actual design process, bellows main body 3 steel plate thickness δ 7-10mm, according to setting allowance and life cycle design, can ensure that air compartment temperature is at 70-170 DEG C of longtime running; Strengthen gusset 4 and intersect splicing by the strip-shaped steel plate after shearing or cutting, reinforcement regular width 25-80mm, thickness δ 7-12mm, under meeting bellows using function condition, main gusset is uniform according to 500-600mm spacing anyhow, can increase auxiliary gusset if desired uniform according to 250-300mm intercross distance, improve bellows overall construction intensity, reduce noise, realize saving material, easy to process.
Heat-insulation layer adopts the rock wool-steel plywood fissure of displacement of 2 layers of 40mm thickness to be arranged in outside reinforcement gusset 4, is finally covered with compression color steel plate 9, significantly reduces bellows radiation loss, good economy performance.
Air distribution plate 1 is given prominence on slag-discharge pipe 2 top 110mm, bottom is given prominence to outside bellows base plate and is arranged 2 joints, convenient transport and slag pipe spreading, slagging flashboard 7 is set bottom slag-discharge pipe 2, uniform according to air distribution plate 1 Aspect Ratio symmetry, about spacing 1500mm, during operation, all wind is effective for air distribution plate 1, the coal seam of top fluidized state can keep fluidisation even for a long time, and slag-discharge pipe 2 in conjunction with the effective deslagging of combustion conditions, can not form the inclined bed of coal combustion layer and putty.
Embodiment 1: air blast air intake surface bellows plate is 90 ° of angles, bellows main body 3 volume about 35 cubic metres, bellows main body 3 adopts 8mm steel plate to make, full weld inside and outside on-the-spot blanking, main reinforcement gusset 4 thickness 12mm, assistant reinforcement gusset thickness 7mm, reinforcement and bellows are fitted both sides, position full weld, after integral manufacturing completion, and the process of inside and outside leak detection anticorrosion spray high temperature lacquer, Surgery therapy adopts 2 layer thickness 40mm, unit weight 120kg/m3 composite plate 5 is staggered, outsourcing die mould ripple color steel 9.
