Refer to Fig. 1 and 2, the utility model embodiment discloses a kind of fire grate of gas generator, disclosed fire grate bag
Include fire grate base 01, sliding bearing 02, revolution boss 03, bracing frame 04 and multi-stage platform.
Revolution boss 03 is set on fire grate base 01 by sliding bearing 02, rotates for being formed with fire grate base 01
Pair, and then revolution boss 03 is rotated with respect to fire grate base 01.
Bracing frame 04 is fixed on revolution boss 03, and is successively provided with gradually to extension from its top to the direction of bottom
The multi-stage stairs shape installation foundation stretched, multi-stage platform includes multiple support platforms, and multiple support platforms are laid on correspondingly
On step-like installation foundation, the top of revolution boss 03 is provided with tower-like dome 08.Refer to Fig. 1, a kind of specific embodiment party
In formula: multiple support platforms can include one level of support platform 12 that the bottom of self-supporting frame 04 is sequentially distributed to top orientation,
Two grades of support platforms 11, three-level support platform 10 and level Four support platform 09.
It is provided with qi-emitting hole, the opening of qi-emitting hole is towards the axle of bracing frame 04 between the step-like installation foundation of adjacent two-layer
To perpendicular.
During work, fire grate base 01 is fixedly linked with the body of heater of gas generator, and revolution boss 03 passes through to slide
Dynamic bearing 02 drives bracing frame 04 to rotate around fire grate base 01, bracing frame 04 is provided with multistage support platform and is used for holding high temperature
Coal is burnt, and on bracing frame 04, can be disposed with qi-emitting hole between the step-like installation foundation of adjacent two-layer, qi-emitting hole
Opening direction is perpendicular with the axial direction of bracing frame 04.This kind of structure can be easy to pure oxygen gas distribution, the direction of qi-emitting hole make its be difficult by
Blocking.It can be seen that, the qi-emitting hole that fire grate disclosed in the utility model embodiment can solve current fire grate is easier to be blocked by coal ash
And then affect the problem of uniform gas distribution.
In the application, the support platform of every one-level is provided with disintegrating slag bar 07, reaches preferable disintegrating slag purpose.Above-mentioned
Support platform all can be made up of heat-resisting steel material.
Referring again to Fig. 2, disclosed in the present embodiment, the fire grate of gas generator can also include lime-ash scraper 06, lime-ash
Scraper 06 is fixed in support platform, and specifically, lime-ash scraper 06 is fixed in two grades of support platforms 11, and lime-ash scraper 06 is used for
Crush cinder.
In the application, the outside of the step-like installation foundation of the bottom of bracing frame 04 is provided with bevel gear 05, umbrella tooth
Wheel 05 is used for engaging with the driving gear on the body of heater of gas generator, by the driving gear 16 on body of heater and bevel gear 05
Engagement reaches the purpose driving whole bracing frame 04 to rotate around revolution boss 03.During driving, regulating stove can be passed through
Driving gear 16 on body to adjust rotating speed with the gearratio of bevel gear 05.
The bottom of fire grate base 01 can be provided with adjusting means 15, and adjusting means 15 is used for adjusting the height of fire grate base 01
Degree.In a kind of specific embodiment: the bottom that adjusting means 15 can include I-steel and be located at I-steel and fire grate base 01
Parallels between end, adjusts the height of fire grate base 01 by I-steel and parallels.
During installing, fire grate base 01 is fixed in gas generator by adjusting means 15, by adjusting means
Adjust the height of bracing frame 04, can ensure that inboard wall of furnace body straightway 14 lower gap of one level of support platform 12 and gas generator
So that ash discharge is smooth in the range of 8-12mm.The inside of fire grate base 01 can be provided with oiling groove, from fire grate base 01
After one end injection lubricating oil, lubricating oil flows in oiling groove, flows through the gap between fire grate base 01 and revolution boss 03,

Qi-emitting hole between the step-like installation foundation of layer implements uniform gas distribution, and then contacts generation after generation vigorous combustion heat release with coal
Coal ash.Coal ash, during fire grate rotation, drives the body of heater of one level of support platform 12 and gas generator in lime-ash scraper 06
Gap between inwall straightway 14 is discharged.Because gasification inner operating is complicated, combustion reaction can not steadily carry out, can produce therebetween
The larger cinder of raw a part of particle diameter is difficult to be expelled directly out, for this reason, lime-ash hang knife 06 in fire grate rotation process with body of heater in
The cinder that on wall straightway 14, the cooperation of raised break bar can be larger to particle diameter produces squeezing action, is allowed to be broken for particle diameter little
Cinder is thus smoothly discharge downwards.The disintegrating slag bar 07 being distributed in each support platform also can be to cinder in fire grate rotation process
Produce grinding, fragmentation.
Disintegrating slag bar 07 is detachably arranged, during maintenance, operator can realize disintegrating slag bar 07 by dismounting
Change.In the application, multi-stage platform can be fastened on the multi-stage stairs shape peace of bracing frame 04 for heat-resisting steel sheet and plate material with point lobed formula
On the basis of dress.When the support platform of certain one-level needs to change with bracing frame 04, this grade of support platform can be fixed by dismounting
Securing member realize.Tower-like dome 08 is removably disposed in the top of bracing frame 04, is conveniently replaceable, and therefore can greatly reduce
The unit replacement operation easier of fire grate.Change consumable accessory by the way rather than by fire grate integral replacing, simplify maintenance behaviour
Make to reduce financial cost, extend fire grate service life, increased gasification furnace parallel-adder settle-out time, bring considerable economy
Benefit.
Based on fire grate disclosed in the utility model embodiment, the utility model embodiment is also disclosed a kind of coal gas and occurs
Stove, disclosed gas generator also includes the fire grate described in any one in foregoing embodiments.
Herein, each preferred version only emphasis describe different with other schemes, as long as each preferred version
