Abstract
The utility model discloses a kind of biomass boiler feeder, arrange several catch between the roof of the arrival end of its charging cavity and diapire, the middle part of charging cavity is communicated with an airduct, the hinged swingable baffle plate of the roof of the port of export of charging cavity.Apply this biomass boiler feeder, biomass fuel blanking is smooth and easy, can stop tempering.
Description
Technical field
The utility model belongs to the auxiliary equipment of boiler, specifically a kind of device giving the charging of biomass boiler burner hearth.
Background technology
Biomass fuel is because the carbon dioxide content produced after its burning is close to zero, and sulphur, nitrogen content are extremely low, and therefore, the toxic emission of biomass boiler can not, to environment, be the new forms of energy of a kind of low cost, environmental protection.The apparatus for feeding of biomass boiler, structurally larger difference is deposited with the apparatus for feeding of traditional coal-burning boiler, main cause is that biomass boiler adopts biological substance shaped granule as fuel, easily there is putty phenomenon when blanking in granular biomass molding fuel, and the granular fuel be transported on fire grate is easily deposited in a place, cause fuel insufficient, create black smoke, create environmental pollution, therefore, for putty and the uneven phenomenon of blanking, Chinese patent literature CN201706520U proposes solution, but, because boiler furnace is in burning running, tempering phenomenon can be there is, flare anti-channeling enters the passage of boiler feed equipment, unexpected burning is produced at passage place, if do not take measure to stop, fire alarm can be caused to occur, lead to fire incident.
Utility model content
In order to solve prior art Problems existing, the utility model provides a kind of anti-backfire biomass boiler feeder.
In order to realize above object, the technical scheme that the utility model is taked is: a kind of biomass boiler feeder, comprises charging cavity, arranges several catch between the roof of the arrival end of described charging cavity and diapire; The middle part of described charging cavity is communicated with an airduct; The hinged swingable baffle plate of the roof of the port of export of described charging cavity.
Further, the cross section of described catch is half-circle-arc shape or V-arrangement shape.
Described charging cavity has multiple charging aperture arranged side by side.
Described airduct comprises a blast pipe and multiple points of airducts.
Compared with prior art, the utility model biomass boiler feeder, owing to being provided with catch, evacuates biomass fuel effectively; Owing to being provided with airduct, strengthening the mobility of biomass fuel under the action of the forces of the wind and make charging cavity lane form malleation, preventing tempering; Owing to being provided with baffle plate, effectively intercept the tempering of anti-channeling during burner hearth malleation.
Accompanying drawing explanation
Fig. 1 is the structural representation of living beings boiler feed device.
Fig. 2 is the sectional view of living beings boiler feed device.
Detailed description of the invention
As shown in Figure 1, the main body of biomass boiler feeder is charging cavity.The inner chamber of charging cavity is square body structure, and relative to boiler body, it is obliquely installed on the whole, is conducive to fuel and slips into boiler furnace along the passage of charging cavity.
In order to make uniform fuel and evacuation point falls into burner hearth, between the diapire and roof of the arrival end 1 of charging cavity lane, be gripped with some catch 2, biomass fuel is shunted through catch, thus plays the effect of evacuating fuel.
In order to make the smooth blanking of fuel, be communicated with airduct 3 at the roof of charging cavity channel middle 4.Airduct 3 comprises blast pipe 31 and some points of airducts 32.Airduct 32 axis is divided to become 20 ~ 30 degree of angles with charging cavity lane blanking direction line.During blanking, wind is blown into from blast pipe, divides equally air quantity, blowed by uniform fuel through a point airduct.While blowing, malleation is produced to burner hearth, can tempering be prevented.
In order to prevent burner hearth tempering breaking out of fire, at the hinged baffle plate 7 of the roof 6 of charging cavity channel outlet 5, baffle plate is in hanging state.When burner hearth tempering, under the effect of burner hearth flue gas malleation, promote baffle plate and upwards put, make baffle plate closure of feed cavity lane, stop flare along charging cavity lane anti-channeling, produce fire alarm.
As shown in Figure 2, the charging aperture 8 of charging cavity has multiple, and discharging opening 9 only has one.Each charging aperture 8 passage, from top to bottom in trapezoidal shape, is namely in gradually wide formula structure.The cross section of catch 2 is V-arrangement shape or half-circle-arc shape.
Claims (4)
1. a biomass boiler feeder, comprises charging cavity, it is characterized in that: arrange several catch between the roof of the arrival end of described charging cavity and diapire; The middle part of described charging cavity is communicated with an airduct; The hinged swingable baffle plate of the roof of the port of export of described charging cavity.
2. biomass boiler feeder according to claim 1, is characterized in that, the cross section of described catch is half-circle-arc shape or V-arrangement shape.
3. biomass boiler feeder according to claim 1, is characterized in that, described charging cavity has multiple charging aperture arranged side by side.
4. biomass boiler feeder according to claim 1, is characterized in that, described airduct comprises a blast pipe and multiple points of airducts.
