Abstract
The structure of the invented hook-hang moving blade chain grate, except for such components of base, driving shaft, chain wheel, driven drum, tensioner and coal hopper which are basically identical to those of general chain grate, is characterized by its chain grate belt ring formed from two-fork shaped chain segments whose heads and tails are correspondent, and both sides respectively are equipped with rollers, and a long pin axle is permeated through each two roller, and the hitched moving blode grate segments which are respectively hitched on the long pin axles, and the chain belt is covered by grate segments. Said invention is simple in structure, good in performance and easy to manufacture.
Description
The invention belongs to the boiler plant technical field, relate to a kind of Industrial Boiler hook-hang moving sheet chain grate.
Industrial Boiler generally adopts traveling-grate stoker at present.Light-duty continuous band fire grate, its chain band structure be by little fire grate segment or be combined into bulk fire grate segment and drive chain sheet and be in the same place by the axle string of having strong market potential, loading and unloading and when changing fire grate segment, and the axle of must will having strong market potential is extracted out, therefore can only the operation of blowing out ability; Scale chain grate, its structure is that fire grate segment is embedded between the two clamping plates, clamping plate are fixed on the active chain with pin, the axle of having strong market potential passes the pitch sleeve pipe respectively organize stove chain and the fire grate of multiple operation is together in series and has formed the chain belt of a sealing, though loading and unloading and change fire grate segment needn't blowing out, but become flexible clamping plate, work is still difficult.
The purpose of this invention is to provide a kind of hook-hang moving sheet chain grate for boiler, its fire grate of living sheet directly is hooked on the bearing pin, and is simple in structure, in light weight, in the fire grate running, just can load and unload the replacing fire grate segment easily.
This hook-hang moving sheet chain grate for boiler has general chain fire-gate base, driving shaft, sprocket wheel, passive cylinder, tensioning apparatus, parts such as coal bunker, it is characterized in that: the chain band is end to end by two fork-shaped chain sheets, two rollers are equipped with in both sides, run through with the axle of having strong market potential, and row row is composed in series the chain belt of a sealing, the hook-hang moving sheet fire grate segment is hooked on the axle of having strong market potential respectively in an orderly manner, the roller on both sides is spacing with two coupler bodies of fire grate segment, and fire grate plate face is topped with the chain band, forms fire grate chain face.
The fire grate operating condition is: machine startup, transmission of power is carried out in roller and sprocket engagement, driving active chain and fire grate is moved on the grate base stent cover by holding by roller, when each row's hook-hang moving sheet fire grate segment is rotated down by back roll, coupler body turnability because of fire grate segment deadweight factor and fire grate segment, making fire grate segment is that the axle center is rotated down an angle with the axle of having strong market potential, and collides with the active chain, is removed the dust stratification on fire grate segment surface automatically.
The advantage of this hook-hang moving sheet chain grate for boiler is: fire grate segment has covered the drive chain band, and their direct and not red-hot grates are contacted, and directly is not heated, though and fire grate segment contacts with coal and directly is heated, and do not stress, thereby performance is good, motion is seldom broken down flexibly; Two to be that fire grate segment is in service be rotated down by back roll for it and since the coupler body of deadweight fire grate segment with the bearing pin for angle of garden heart rotation and chain initiatively collide, the dust stratification that can will be bonded in the fire grate segment surface is removed automatically; The 3rd is that sheet fire grate alive directly is hooked on the axle of having strong market potential, and fire grate segment is changed in the loading and unloading easily that can be in operation, and it is simple in structure, and the scope of application is wide.
Description of drawings: Fig. 1, hook-hang moving sheet chain grate for boiler chain belt structure chart; Among the figure: 1, drive chain silver, 2, the axle of having strong market potential, 3, roller, 4, the hook-hang moving sheet fire grate segment, 5, the grate base support.Fig. 2, hook-hang moving sheet fire-grating chip architecture figure; Cutaway view is looked on Fig. 3, a hook-hang moving sheet fire grate segment left side.Among the figure: 4
1, fire grate segment plate face, 4
2, air vent, 4
3, coupler body, 4
4, every wind stiffener, 4
5, reinforcement.
Below further specify the structure of this hook-hang moving sheet chain grate for boiler with reference to the accompanying drawings: have the essentially identical base support of general traveling-grate stoker, driving shaft, sprocket wheel, passive cylinder, tensioning apparatus, outside the parts such as coal bunker, its special character is seen Fig. 1: two fork-shaped chain sheets, 1 head and the tail are corresponding, and two rollers 3 are equipped with in both sides, axle 2 runs through by having strong market potential, so row connects mutually, forms the chain band of a sealing, coupling type sheet fire grate segment 4 alive, be hooked on the axle 2 of having strong market potential, two rollers 3 on both sides are with coupler body 43 location, and fire grate segment plate face is topped with the chain band, forms a fire grate chain face.See Fig. 2, Fig. 3, on 41 in the fire grate plate face of hook-hang moving sheet fire grate 4, air vent 4 is arranged
2, reinforcement 4 is arranged below
5, a side has every wind stiffener 44, two coupler bodies 4 of lower link

Claims (2)
1, a kind of have base, a driving shaft, sprocket wheel, passive cylinder, tensioning apparatus, the boiler traveling-grate stoker that parts such as coal bunker constitute, it is characterized in that fire grate fork-shaped chain sheet head and the tail relatively, roller is contained in both sides, and axle runs through by having strong market potential, the sheet fire grate segment of living is hooked on the axle of having strong market potential, the both sides roller is spacing with coupler body, and fire grate plate face is topped with the chain band, so mutually the traveling-grate stoker band of series connection.
2, hook-hang moving sheet chain grate for boiler as claimed in claim 1 is characterized in that the sheet fire grate of living, and on the fire grate plate face air vent is arranged, and reinforcement is arranged below, and a side has every the wind stiffener, connects two coupler bodies.
