Abstract
The invention relates to a feeding device, in particular to a spiral feeder used for fluidized-bed-type fast biomass pyrolysis. A storage bin is arranged above an air seal machine, material in the storage bin is conveyed into the shell of the feeder by virtue of the air seal machine, and biomass is continuously pushed into a fluidized bed reactor by virtue of an auger arranged in the shell. By virtue of mechanical sealing of the air seal machine and pressure separation and air locking of material filled in a conveying pipe, the feeder does not generate back spraying phenomenon; a stirring bar member is arranged in the storage bin, and power is provided for the stirring bar member while the air seal machine rotates to discharge material, so that the stirring bar member moves up and down and stirs the material, and phenomena of bridging, hanging on the wall and the like can be avoided; meanwhile, a variable frequency motor is connected with a gear transmission box to provide power for the auger and the air seal machine, and feed rates of the auger and the air seal machine are guaranteed to be consistent by virtue of speed ratio.
Description
Technical field
The present invention relates to a kind of feed arrangement, particularly a kind of feeding screw for biomass fluid bed fast pyrogenation.
Background technology
China's biomass energy is very abundant, and current national agricultural crop straw can obtain approximately 6.87 hundred million t every year, and approximately 60% can recovery energy, approximately has every year 4.2 hundred million t stalks to can be used as biomass material, amounts to approximately 2.1 hundred million t standard coals; Forestry residue can obtain approximately 1.25 hundred million t every year, amounts to approximately 7,125 ten thousand t standard coals.It is predicted, to the year two thousand fifty, China can develop biomass resource amount and at least can reach 1,500,000,000 t.To effective utilization of living beings, energy problem can not only be solved, and environmental problem can be solved, there is good effect at aspects such as energy-saving and emission-reduction, reduction carbon emission, energy recovery.Fluidized bed type fast pyrolysis technology can be converted to the living beings of low energy densities high-grade bio oil and other energy products, to produce fuel or chemical products, is considered to one of the most potential biomass energy utilization technologies.
In biomass fast pyrogenation process, must guarantee that material enters fluidized-bed reactor continuously, equably, and require feeder and fluidized-bed reactor strictly to seal.Due to features such as living beings have that density is little, angle of repose is large, poor fluidities, in reinforced process, in feed bin, be easy to occur the problems such as bridgings, wall built-up, thereby cause feeding in raw material unstable or stop feed.Biomass fluid bed fast pyrogenation system is positive pressure system, causes the thermal current in reactor to be overflowed if seal bad meeting, and formation is regurgitated, and makes material be difficult to enter reactor.
Existing biomass feeder can't thoroughly solve has the problem such as bridge formation, wall built-up that the reasons such as density is little, angle of repose large, poor fluidity cause due to living beings.Meanwhile, existing biomass feeder can not be guaranteeing continuously, prevent from regurgitating in uniform feeding.These two kinds of factors have limited the development of biomass fluid bed fast pyrolysis technology to a great extent.
Summary of the invention
The object of the invention is the various deficiencies that exist in order to overcome existing biomass feeder, proposed a kind ofly not only can avoid charging smooth but also can prevent the feeding screw for biomass fluid bed fast pyrogenation of regurgitating.
The present invention realizes by following technical approach: feeder housing, airlock, feed bin vertically connect by flange, feeding packing auger is positioned at feeder housing, living beings, in airlock enters feeder housing, then push fluidized-bed reactor by auger, guaranteed charging continuously, evenly.Meanwhile, the material envelope of material in pressing lock wind and feeder housing of airlock has played the effect of counter-jetting resistance; The agitator arm member that is positioned at feed bin is made up of straight agitator arm, curved agitator arm, connecting rod, contact, and one end is connected with bin wall by bolt, other end linking springs member.Straight agitator arm is connected by guide rail with curved agitator arm, welds connecting rod on agitator arm, and connecting rod two ends are contact; The lower end of curved agitator arm contacts with the blade of airlock, by rotatablely moving as agitator arm member provides power of airlock, agitator arm member is moved upward and extrusion spring member.In the time that the lower end of agitator arm member departs from the blade of airlock, spring member is pushed agitator arm member to be about to the blade that rotation is come to, by the stirring material that moves up and down of agitator arm member, avoids occurring the phenomenons such as bridging, wall built-up; Frequency modulation motor driven gear gearbox, for auger and airlock provide power, guarantees that the inlet amount of the two is consistent simultaneously; Feeder housing and speed-changing gear box are bolted on base.
Irregular, different angles layout that described connecting rod becomes, guarantees good disturbance effect.
Described contact is aluminium ball, is welded on connecting rod two ends.
Described spring member is inner is thrust spring.
Compared with prior art, because airlock has good mechanical seal effect, the material of filling between auger and feed pipe can play the effect of material envelope, and that has realized fluidized-bed reactor and feeding screw locks wind every pressing; Owing to being provided with agitator arm member in feed bin, provide power with the rotation of airlock blade, do not need additionally to provide power to realize again the disturbance of material in feed bin, avoid occurring the phenomenons such as bridging, wall built-up.

The specific embodiment
The invention provides a kind of feeding screw for biomass fluid bed fast pyrogenation, below by the drawings and specific embodiments, the invention will be further described.
As depicted in figs. 1 and 2, the structure of this biomass screw feeder is: feeder housing 2, airlock 3, feed bin 4 vertically connect by flange, feeding packing auger 1 is positioned at feeder housing 2, living beings are in airlock 3 enters feeder housing 2, push fluidized-bed reactor by auger 1 again, guaranteed the continuous, even of charging.Meanwhile, the material every pressing lock wind and feeder housing 2 interior materials of airlock 3 seals the effect of having played counter-jetting resistance; The agitator arm member that is positioned at feed bin 4 is made up of straight agitator arm 11, curved agitator arm 13, connecting rod 6, contact 5, one end is connected with bin wall by bolt, other end linking springs member 10, straight agitator arm 11 is connected by guide rail 12 with curved agitator arm 13, on agitator arm, weld connecting rod 6, connecting rod 6 two ends are contact 5; The lower end of curved agitator arm 13 contacts with the blade of airlock 3, by rotatablely moving as agitator arm member provides power of airlock 3, agitator arm is moved upward and extrusion spring member 10.In the time that the lower end of curved agitator arm 13 departs from the blade of airlock 3, spring member 10 is pushed agitator arm member to be about to the blade that rotation is come to, by the stirring material that moves up and down of agitator arm member, avoids occurring the phenomenons such as bridging, wall built-up; Frequency modulation motor 8 driven gear gearboxes 7, for auger 1 and airlock 3 provide power, guarantee that the inlet amount of the two is consistent simultaneously; Feeder housing 2 is bolted on base 9 with speed-changing gear box 7.
