Description
Technical field
The utility model belongs to biomass fuel technical field, is related to a kind of dispensing for biomass fuel front-furnace feeding
Device.
Background technology
Biomass fuel is a kind of Novel clean-fuel, by by agriculture and forestry organic waste material (such as stalk, sawdust, bagasse, rice chaff
Deng) burn, to utilize biomass energy, substitute fossil fuels are as the energy.Biomass fuel is in use, be usually by agriculture
Woods waste etc. is used as raw material, by techniques such as crushing, mixing, extruding, drying, is made variously-shaped (such as blocky, graininess
Deng), and be stored in Bunker, later the biomass fuel in Bunker is directly added to burn in boiler.
During the biomass fuel in Bunker is added into boiler, in order to control feeding coal, usually firing
Shutoff door is set at the blanking port of feed bin, the folding of Bunker blanking port is controlled by shutoff door, and then control front-furnace feeding amount.But
Since shutoff door controls inconvenience, flexibility is poor, and can not carry out the accurate adjusting of feeding coal, thus in actual production, pot
Stove feeding coal often constantly fluctuates, and affects the normal combustion of boiler endogenous substance fuel, or even will produce bridging and block now
As not only influencing being normally carried out for fill process, also resulting in accident.
Utility model content
The purpose of this utility model is exactly to provide one kind in order to overcome the problems of the above-mentioned prior art and can easily be accommodated
Boiler feeding coal and the safe and reliable proportioner for biomass fuel front-furnace feeding.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of proportioner for biomass fuel front-furnace feeding, the device include shell and are arranged in shell
Centering type rotary feeder structure, the top of the shell are equipped with feed inlet, and bottom is equipped with discharge port, the feed inlet with go out
It is vertically equipped with material channel between material mouth, is equipped with camber side plate and board-type side plate on the shell relatively, it is described
Centering type rotary feeder structure be arranged between camber side plate and board-type side plate.Biomass fuel enters material by feed inlet
In channel, the adjusting through centering type rotary feeder structure is discharged according to default feeding coal by discharge port.
The shell includes end to end the first side wall, second sidewall, third side wall and the 4th side wall successively, described
The first side wall be mutually parallel with third side wall, the second sidewall is mutually parallel with the 4th side wall, the board-type side
Plate is arranged in second sidewall, and the camber side plate is arranged on the 4th side wall.The first side wall, second sidewall, third side wall
And the 4th side wall enclose together, form shell, centre for for material by material channel.Camber side plate and board-type side plate
It is oppositely arranged, is the working chamber of centering type rotary feeder structure between camber side plate and board-type side plate.
The centering type rotary feeder structure includes being arranged horizontally between camber side plate and board-type side plate
Shaft, multiple circumferentially uniformly distributed in shaft and feed baffle compatible with camber side plate and board-type side plate along shaft
And the shaft driving motor being connect with rotating shaft transmission.Shaft driving motor drives shaft rotation, makes to enter material by feed inlet
The biomass fuel in channel is moved through material channel to discharge outlet successively under the action of multiple feed baffles.It is fed baffle
It is adapted with board-type side plate, avoids gap of the biomass fuel across feed baffle and board-type side plate from falling, influence
Feeding coal control accuracy.
Horizontal distance between the center line of the shaft and the 4th side wall is less than the center line and second sidewall of shaft
Between horizontal distance.The horizontal position of shaft centerline forms eccentric type structure, enters object by feed inlet close to the 4th side wall
The biomass fuel in material channel can only be fallen on the feed baffle of shaft side, be conducive to the smooth rotation of shaft, while biology
The cooperation of the gravity of matter fuel and feed baffle, can provide certain power for the rotation of shaft, thus reduces and turn
The load of axis driving motor.
The center line of the shaft and the 4th side wall are located in same vertical plane.I.e. the center line of shaft is just and material
Channel is staggered completely, avoids entering the biomass fuel of material channel by feed inlet while fall in shaft both sides, increases shaft and turn
Resistance when dynamic.
The inner end of the feed baffle is fixed in shaft, and the minimum range between outer end and board-type side plate is
3-5mm.When being fed in flapper to material channel, and being located at horizontality, it is fed outer end and the board-type side plate of baffle
The distance between minimum, material channel can be closed.It, will since the diameter of biomass fuel pellet is generally 6-10mm
Be fed baffle outer end and board-type side plate between minimum range be set as 3-5mm, can either avoid biomass fuel pass through to
Gap between material baffle and board-type side plate is fallen, while can make that there are suitable between feed baffle and board-type side plate again
Gap avoids the two from being in direct contact friction and cause to be lost.
The feed baffle is equipped with buffer board, which fits with feed baffle.Biomass fuel is by feeding
When mouth is fallen on feed baffle, in order to reduce impact of the biomass fuel to feed baffle surface, setting is slow on feed baffle
Punching, the buffer board have certain elastic buffer effect, can extend the service life of device.
The material of the buffer board is rubber or plastics as a preferred technical solution,.
The shell is equipped with maintenance door.Maintenance door is convenient at any time overhauling device inside.
The utility model is in practical application, biomass fuel is entered by feed inlet in material channel, and is fallen and kept off in feed
On plate；With the rotation of shaft, the biomass fuel being fed on baffle moves gradually downward；When the feed baffle in material channel
When being swung down to heeling condition by horizontality, biomass fuel progressively disengages feed baffle, and is moved to discharge outlet, most
It is fallen by discharge port.
Compared with prior art, the utility model has the characteristics that：
1) the utility model is arranged between Bunker and boiler, the biomass fuel in Bunker is rotated through centering type
The adjusting of feeder is steadily fallen into boiler according to preset feeding coal, ensure that the normal of boiler endogenous substance fuel
Burning, avoids the generation of bridging clogging, securely and reliably；
2) feeding coal of biomass fuel can be conveniently and efficiently adjusted by the rotating speed of change shaft driving motor, and
Corresponding feed baffle can be replaced, easily operated, flexibility is good according to the physical characteristic of different biomass fuels；
3) center line of the center line from material channel of shaft is located in different vertical planes, forms eccentric structure, makes life
Biomass fuel can only be fallen on the feed baffle of shaft side, be ensure that the smooth rotation of shaft, reduced shaft driving motor
Load, good operating stability, service life is long.
