Description
Technical field
This utility model relates to a kind of wear-resistant composite plate welding Circular ventilation door, belongs to Circular ventilation door technical field.
Background technology
Circular ventilation door is used primarily on boiler of power plant coal dust and wind blending transportation pipeline, and regulation Circular ventilation door aperture controls boiler coal-ash input, reaches to control the purpose of boiler output load size.Owing to mixture high temperature, the high speed of coal dust with wind pass through Circular ventilation door, cause for preventing Circular ventilation door from damaging power plant's blowing out to shut down, reduce the time between overhauls(TBO).Need the high temperature resistant deformation of Circular ventilation door to prevent clamping stagnation, reduce leakage position, and there is extremely strong wearability.
Existing Circular ventilation door is all to use casting and by Flange joint, therefore there is problems in that 1, due to casting the selection of material hardness higher so toughness is poor, after Flange joint, at bolt hole, be there will be crackle by high temperature and pipeline alternating force effect for a long time, easily cause fracture.2, two flange connections sealing life-time service often occur that damage causes Coal powder spray phenomenon, pollute environment.3, wearability improves, and hardness must increase, and welding performance is deteriorated, and can only use Flange joint.4, wearability can only improve to a certain degree, has the biggest limitation.5, the time between overhauls(TBO) is short, needs periodic inspection, and maintenance cost is high.6, many because of flange bolt, dismounting difficulty.As used integral material to weld Circular ventilation door, need to consider and pipeline welding performance, hardness needs to reduce, and wears no resistance.
Summary of the invention
The purpose of this utility model is to solve the problem that above-mentioned prior art exists, i.e. higher so toughness is poor due to casting the selection of material hardness, after Flange joint, at bolt hole, be there will be crackle by high temperature and pipeline alternating force effect for a long time, easily cause fracture.Two flange connections seal life-time service and often occur that damage causes Coal powder spray phenomenon, pollute environment.Time between overhauls(TBO) is short, needs periodic inspection, and maintenance cost is high.And then provide a kind of wear-resistant composite plate to weld Circular ventilation door.
The purpose of this utility model is achieved through the following technical solutions:
nullA kind of wear-resistant composite plate welding Circular ventilation door，Including: air door shell、Air door door-plate、Axle sleeve inlay、Bottom axle sleeve、Bottom door-hinge、Upper shaft sleeve、Top door-hinge and air door axle sleeve，Described air door shell is circular configuration，Air door shell is made up of outer layer low-alloy high-tensile structural steel plate and internal layer hot compound high-wear alloy sheets，Outer layer low-alloy high-tensile structural steel plate and internal layer hot compound high-wear alloy sheets are combined with each other，Air door door-plate is arranged on the inside of internal layer hot compound high-wear alloy sheets，The bottom of described internal layer hot compound high-wear alloy sheets is provided with axle sleeve inlay，Bottom axle sleeve is arranged on the bottom in axle sleeve inlay，The upper end of bottom door-hinge is fixing with the lower end air door axle sleeve of air door door-plate to be connected，The lower end of bottom door-hinge is rotationally connected with bottom axle sleeve，The upper end of air door door-plate is fixed with air door axle sleeve，The top of internal layer hot compound high-wear alloy sheets is provided with upper shaft sleeve，The top of top door-hinge is rotationally connected with upper shaft sleeve，The bottom of top door-hinge is fixing with air door axle sleeve to be connected.
The beneficial effects of the utility model: 1, owing to using Circular ventilation door and pipeline welding, non-bolt porous dehiscence stricture of vagina, add reliability.2, without being tightly connected between wear-resistant composite board welding Circular ventilation door and pipeline, do not have phenomenon of dusting and protect the environment from pollution.3, due to housing outer layer material be 16Mn easily and pipeline welding.4, it is that heat is compound relatively independent due to internal layer antifriction alloy and outer layer 16Mn plate, so internal layer antifriction alloy can at utmost improve hardness and wearability, the most wear-resisting.5, the time between overhauls(TBO) is long, is 8～10 times of existing common Circular ventilation door.6, convenient disassembly, it is easy to install.
