Abstract
The utility model relates to a fire grate of a garbage cracking furnace, which is formed by more than two fire bars side by side. A gap exists between adjacent fire bars at least in a furnace body, the two ends of each fire bar are respectively extended out the furnace body, and the fire bars are driven by power. The fire grate of the garbage cracking furnace is characterized in that each fire bar is in a hollow structure, and the surface of each fire bar at least in the furnace body is in a structure of a corrugated rotating body or screws. The linked side-by-side fire bar not only can support and stir garbage to be dried or cracked on the upper part but also can accurately control the blanking speed. The fire grate of the garbage cracking furnace has reasonable structural design, constant gaps and uniform blanking, and the corrugated surfaces between adjacent fire bars are mutually matched. The fire grate not only can break, crack and carbonize comburant but also is beneficial to high-temperature air current rising and stirring and barbecuing to impel crack and carbonize comburant. The linked fire grate is driven by power for positive and negative alternating, which can greatly ensure that the comburant is fully cracked and combusted. The blanking speed of the comburant can be regulated.
Description
Technical field:
The utility model belongs to biomass garbage treatment facility field, the improvement of particularly a kind of incinerator or rubbish high-temperature cracking stove fire grate.
Background technology:
The incinerator of existing biomass garbage or the body of heater of pyrolysis furnace are divided into upper and lower two spaces, and top is rubbish oven dry or Pintsch process chamber, and the bottom is the combustion chamber; Be provided with rotatable fire grate between two Room; Fire grate had both supported the rubbish on top, and the high temperature hot gas rising passway is provided, and made rubbish oven dry or cracking; Can let the rubbish of carbonization abstemiously enter the combustion chamber again, needing of burning endlessly is provided.Patent No. CN200410000186.7; The pyrolysis furnace of heating in disclosed a kind of rubbish; Its fire grate adopts fixed, and is equipped with a rotating turret, in order to stir top wait dry rubbish with help that rubbish falls into that the combustion chamber supplies burning need; There are defectives such as blanking is not smooth in this structure in practice.And patent No. CN200810071650.X, rocking furnace grate by name, grate is embarked on journey by many fire bars side by side, and the fire bars surface is long to have many platoon leaders bar tooth, and is fixedly connected by decelerator.Rectangular tooth on this fire bars can stir into the rubbish of piece carbonization in theory, and during actual motion, the broken amount that falls of the carbide of caking is difficult to control.How inventing a kind of fire grate simple in structure promptly becomes the object of research.
Summary of the invention:
The purpose of the utility model is that design is a kind of through the pyrolysis furnace fire grate of heating in the rubbish that rotary furnace bar is formed side by side, blanking is controlled.
The utility model technical scheme is achieved in that a kind of waste cracking furnace fire grate; Formed side by side by two above fire bars, in body of heater, have the gap between adjacent fire bars at least, the fire bars two ends are stretched out outside the body of heater respectively; Fire bars is by power drive; It is characterized in that fire bars is a hollow structure, the surface of the fire bars in the body of heater becomes the ripple rotary body at least, and perhaps spiral lamination selects a structure.The fire bars side by side of interlock can support and stir that top waits to dry or the rubbish thing of cracking, can accurately control blanking speed again; The hollow structure of fire bars so that cooling fluid flows, is avoided the fire bars scorification.
The ripple on said fire bars surface, perhaps spiral lamination offers 1-5 the groove that splits with parallel axes.Utilize axis to split groove, form sawtooth effect, the especially fire bars of spiral lamination structure, existing radial cuts has the axial push double action again, helps the control blanking.
Said fire bars external waviness is the structure of selecting of sinusoidal waveform, square waveform or triangular waveform.
Said fire grate is the above sandwich construction of one deck, every layer with adjacent layer in fire bars parallel and be dislocatedly distributed.Mat stratiform fire grate is divided into the different functions district with body of heater, like combustion zone, cracking zone and baking zone; Form each other between the adjacent layer fire grate and support, avoid rubbish directly to drop.
Said fire grate is the above sandwich construction of one deck, every layer with adjacent layer in fire bars become vertical distribution.Effect is with above-mentioned the same, and every layer of fire grate of staggered designs can both play the support and control effect to the rubbish that falls.
Said adjacent fire bars becomes the rightabout rotation under power drive.Avoid rubbish is pushed to a side of body of heater, what also help treating comburant blends and stirs the baking cracking.
The utlity model has reasonable in design, clearance constant, blanking is even; Corrugated surface between adjacent fire bars or spiral lamination surface cooperatively interact; Not only can broken charing after-combustion thing, also help high temperature gas flow and rise and stir barbecue, impel comburant cracking charing.Being rotated by power-actuated fire grate positive and negative alternate, is the strong guarantee of abundant cracking of comburant and burning, and comburant blanking adjustable-speed joint.
Description of drawings:
Below in conjunction with concrete legend the utility model is further specified:
Fig. 1 fire bars schematic perspective view
Fig. 2 fire bars two schematic perspective views
Fig. 3 fire grate and body of heater concern sketch map
Wherein
1-fire bars 2-splits groove 3-body of heater
The specific embodiment:
With reference to Fig. 1, fire bars 1 is a hollow structure, and 1 surface of the fire bars in the body of heater 3 becomes the ripple rotation body structure at least, and offer 1-5 with parallel axes split groove 2.Fire bars 1 external waviness is the structure of selecting of sinusoidal waveform, square waveform or triangular waveform.
Fig. 2, fire bars 1 surface is the spiral lamination structure in this legend, and offers along the parallel axes direction and to split groove 2.The spiral lamination structure on fire bars 1 surface is a priority scheme, and its spiral lamination can produce axial compression power when fire bars 1 rotation, matching surface split groove 2, can effectively cut the carbide of caking, and the rubbish thing of pullling moving oven dry.
Fig. 3 can design one or more layers fire grate in biomass garbage pyrolysis furnace and the incinerator, and every layer of fire grate formed by two above fire bars 1 side by side, and there is the gap in 1 of adjacent fire bars at least in body of heater 3, is beneficial to fuel whereabouts and thermal current and rises.Article two, 1 pair of comburant of fire bars of rotation can produce pinching pressure, fragmentation in opposite directions, drives the function of blanking downwards; And or opposing rotation, can encircle the comburant on loose top.If spiral lamination fire bars 1 also can produce axial compression and cutting, with adjacent fire bars 1 in opposite directions during perhaps opposing rotation, can produce more rational blanking and control, be difficult for skidding.
Like Fig. 3, stretch out body of heater 3 outer fire bars 1 ends and be connected with power transmission, perhaps many fire bars 1 form joint-action mechanism, and are unified by power drive, realize the purpose of Synchronization Control.
