Description
[technical field]
The utility model relates to combustion furnace technical field, specifically a kind of automatic rotation deashing combustion furnace.
[background technology]
Traditional biomass combustor adopts fixed grate, (i.e. primary combustion in long-term combustion process; Second-time burning) easily coking, cause biomass fuel not easily Thorough combustion, the thermal efficiency is low, and this measure not only adds fuel cost, and fire grate can not rotate, and for a long time at the same area high-temp combustion, fire grate parts easily damage, and maintenance cost increases greatly.The biomass fuel afterburnt, remaining lime-ash, in some cycles, necessary blowing out, manually removes the gred, the thermal efficiency; Waste of fuel is serious, and the working strength of fireman also strengthens simultaneously.And artificial except cinder notch is as poorly sealed, have a small amount of flue gas and thin lime-ash spilling, seal operation is loaded down with trivial details, can not accomplish workshop dustlessization, is not easy to shop safety and produces.
[summary of the invention]
The purpose of this utility model is the defect overcoming prior art existence, provides a kind of automatic rotation deashing combustion furnace of new structure.
For achieving the above object, design a kind of automatic rotation deashing combustion furnace, comprise burner hearth, feeding material component, base, be provided with fire grate in base, assembly of blowing, assembly of slagging tap, it is characterized in that, be equidistantly provided with some airducts in burner hearth, sidewall and the roof of every root airduct are equidistantly provided with some steam vents, the bottom of every root airduct is provided with air admission hole, is connected with the air-supply assembly steam vent in base; The fire grate of combustor adopts cylinder, take the center of circle as benchmark circumferentially decile four subregions, circular fixing reinforcing bar is equipped with at the fire grate back side under first, second, third subregion, when fire grate turns in the 4th subregion clinker area, fire grate falls automatically, lime-ash on fire grate then naturally drop into just working slag tap in auger nowel, high temperature resistant rotatable bearing is equipped with at fire grate center, and axle lower end is connected to adjustable speed variable-frequency motor and interior outer rotary table through chain pitch wheel, the movable fire grate of structure reciprocal upset in 90 °.
Fire-gate side wall has small ventilating holes, and oxygen circulates.
Described feeding material component adopts light-duty auger to realize mechanical feed, and the blanking auger with 45 ° of gradients coordinates the living beings hopper be positioned at above blanking auger to feed intake to combustion chamber.
Also auger type mucking machine can be housed in base, auger type mucking machine is provided with slag inlet, and to ranked fourth subregion clinker area suitable with stove, coordinates rotationally reciprocating fire grate, can realize automatically uninterruptedly slagging tap.When not blowing out, slag tap through auger.
The slag notch of auger type mucking machine is provided with black box, slag notch good airproof performance, reduces workshop air dust amount, truly accomplishes Workshop Production dustlessization.
Base bottom is provided with universal wheel, is convenient in production site mobile.
Described air-supply assembly adopts segmented air-supply, and on the first zoned grate, outlet air door air quantity regulates high; On second, third zoned grate, outlet air door air quantity regulates little; When fire grate rotates the 4th subregion, fire grate only has the lime-ash of thorough after-flame, now without the need to air distribution, air outlet closes, and adopts segmented air-supply, and biomass fuel is on the first zoned grate, and air door air quantity regulates high, thus carries out aerobic vigorous combustion.On second, third zoned grate, fire grate is the clinker area after burning, but also has a small amount of unburnt fuel, so join a small amount of wind, when aerobic, fuel is burnt again, and fuel availability improves greatly.When fire grate rotates the 4th subregion, fire grate only has the lime-ash of thorough after-flame, now without the need to air distribution, lime-ash directly falls into slagging-off auger bucket case, through work auger, when not blowing out, be uninterruptedly extracted into beyond combustor body, substantially increase boiler service efficiency, reduce the working strength of fireman.
Automatic rotation deashing combustion furnace of the present utility model, novel structure is unique, easy to use, production efficiency is high, when not blowing out, manually easily uninterruptedly can go out lime-ash from ashpit, improve the thermal efficiency, when reducing fuel cost, the working strength of fireman also reduces relatively.The auger type mucking machine be equipped with, without the need to manual intervention, can realize automatically uninterruptedly slagging tap.Slag notch good airproof performance, reduces workshop air dust amount, truly accomplishes Workshop Production dustlessization.

[detailed description of the invention]
Now being further elaborated the technical solution of the utility model for accompanying drawing, is clearly for a person skilled in the art.
As shown in Figure 1-2, automatic rotation deashing combustion furnace, comprises burner hearth, feeding material component, base, is provided with fire grate, assembly of blowing, assembly of slagging tap in base,
First, be equidistantly provided with some airducts in burner hearth, sidewall and the roof of every root airduct are equidistantly provided with some steam vents, and the bottom of every root airduct is provided with air admission hole, are connected with the air-supply assembly steam vent in base;
Secondly, the fire grate of combustor adopts cylinder, take the center of circle as benchmark circumferentially decile four subregions, circular fixing reinforcing bar is equipped with at the fire grate back side under first, second, third subregion, when fire grate turns in the 4th subregion clinker area, fire grate falls automatically, lime-ash on fire grate then naturally drop into just working slag tap in auger nowel, high temperature resistant rotatable bearing is equipped with at fire grate center, axle lower end is connected to adjustable speed variable-frequency motor and interior outer rotary table through chain pitch wheel, the movable fire grate of structure reciprocal upset in 90 °, fire-gate side wall has small ventilating holes, and oxygen circulates.
Then, feeding material component adopts light-duty auger to realize mechanical feed, and the blanking auger with 45 ° of gradients coordinates the living beings hopper be positioned at above blanking auger to feed intake to combustion chamber.Also auger type mucking machine can be housed in base, auger type mucking machine is provided with slag inlet, and to ranked fourth subregion clinker area suitable with stove, coordinates rotationally reciprocating fire grate, can realize automatically uninterruptedly slagging tap.When not blowing out, slag tap through auger.The slag notch of auger type mucking machine is provided with black box, slag notch good airproof performance, reduces workshop air dust amount, truly accomplishes Workshop Production dustlessization.
