Description
Technical field
It the utility model is related to a kind of boiler feeding device, and in particular to a kind of biomass boiler negative pressure charging gear, use
In the feeding system of biomass boiler.
Background technology
Biomass fuel species is various, such as wood chip, bark, branch, straw, bamboo, building template, ordinary circumstance
Lower straw, bark etc. directly enter stove burning, and the only larger wooden unit of volume, branch etc. needs to carry out simple crushing, fuel
Particle diameter is difficult to control, feed pipe easily because fuel granularity is excessive or fuel conglomeration block, boiler shutdown is caused when serious, seriously
Influence the normal operation of heat power equipment.Therefore, reliable charging gear is the essential condition for ensureing biomass boiler normal operation
One of.
Bio-fuel volatile matter is high, moisture is more, enters and detonation easily occurs after stove, during detonation the fluctuation of furnace pressure can lead
Flue gas is caused along feed pipe anti-channeling, the fuel in the feed pipe that ignites, when serious can feed bin before ignition furnace, trigger fire.Generally with close
Flue gas anti-channeling when sealing wind to prevent malleation in stove, but when being fed not smooth or blanking blockage, oxygen that sealing air is brought
The combustion velocity of fuel in feed pipe is accelerated, does not have fire-retardant effect.Therefore the more preferable charging gear of flame retardant effect
It is an important factor for ensureing safe operation of the boiler.
The content of the invention
The purpose of this utility model is in view of the above-mentioned problems, provide a kind of biomass boiler negative pressure charging gear, to pass through
The propulsion fire-retarding device of biomass boiler negative pressure charging gear, biomass boiler continuous-feeding is realized, prevent anti-channeling flue gas from igniting
Do not enter stove fuel in feeding system.
The utility model is achieved like this, biomass boiler negative pressure charging gear are mainly fire-retardant including hopper, propulsion
Device and material blanking tube, the connection of hopper bottom promote fire-retarding device, promote fire-retarding device bottom to connect inclined material blanking tube；Its feature
It is：Described propulsion fire-retarding device is close by fire-retarding device housing, rotor, movable vane, fixed blade, resetting means, elasticity
Shrouding I and elastic packing plate II form, installation rotor in middle part in fire-retarding device housing, install some fixed blades on rotor, often
Movable vane is installed again on individual fixed blade, resetting means is housed between fixed blade and movable vane, fire-retarding device housing is right
Lower section installing arc elastic sealing plate I, fire-retarding device housing upper left side installing arc elastic sealing plate II；Material blanking tube bottom is inserted
Material seeding airduct.
Further, above-mentioned biomass boiler negative pressure charging gear, described material blanking tube bottom bore are more than upper port
Footpath, is flaring reducing pipe structure, and the angle of flare is 1~5o。
For the charging gear of biomass boiler, it is provided between hopper and material blanking tube and promotes fire-retarding device, prevent charging from tying
Group obstruction and burner hearth emit malleation flue gas anti-channeling ignite supplied materials initiation interruption of service；The propulsion fire-retarding device is by fire-retarding device shell
Body, rotor, movable vane, fixed blade, resetting means, elastic packing plate I and elastic packing plate II form；The propulsion is fire-retardant
Device is rotated by motor driven rotor clockwise, and biomass fuel folder is brought to material blanking tube between the blades, then passes through blanking
Pipe enters hearth combustion；The fixed blade is fixed on rotor, passes through resetting means pin between movable vane and fixed blade
Axis connection, when supplied materials is larger, movable vane, which can deflect, reserves sufficient space so that big briquette fuel passes through, anti-rotation stop
Subcard is dead；Preloading spring is provided with the resetting means, pretightning force is more than the limit malleation that can be generated when furnace implosion fires, prevented
Only the flame-retarding characteristic for promoting fire-retarding device is destroyed because impact caused by detonation causes movable vane to act；It is described to promote fire-retardant dress
The movable vane top put is brought into close contact with elastic packing plate, is made completely separated between hopper and material blanking tube；The material blanking tube
Flaring reducing pipe structure can prevent fuel to be provided with material seeding airduct in this section conglomeration jam, material blanking tube lower end；Promote fire-retarding device
Be equipped with inspection door on material blanking tube, convenient maintenance cleaning.
It is of the present utility model to have the technical effect that：Efficiently solve biomass boiler and be fed not smooth, easy jam and fuel
Easily feed pipe burns the problem of, there is feed unobstructed, be not easy jam, feed is continuous reliable, the advantages that good flame retardation effect.
