Biomass fuel boiler bidirectional rotation apparatus for feeding
Technical field
The present invention relates to a kind of biomass fuel boiler bidirectional rotation apparatuss for feeding.
Background technology
Biomass fuel pellet, which is used in boiler combustion field, not only can greatly reduce making for the traditional fuels such as coal
Dosage, and biomass fuel is the bigger dye granule of the density that is process by discarded Wheat Straw, it can be by wheat straw
Stalk etc. carries out secondary use, increases economic efficiency, and reduces burning cost, and biomass dyestuff is because it is with larger density,
Therefore the time burnt in boiler is long, heat insulation effect is more preferable, saves fuel.
But biomass fuel pellet needs to realize equivalent charging during charging, could preferably control boiler in this way
Interior temperature and the duration and degree of heating preferably realizes clean-burning purpose, and existing biomass fuel neither one in charging closes
The feeding mechanism of reason, precision causes charging blindly to can not achieve the purpose of equivalent charging, and the temperature in boiler is caused to neglect height
Suddenly low, it is unfavorable for the efficient utilization of boiler.
Invention content
In view of the above problems, the present invention is intended to provide biomass fuel boiler bidirectional rotation apparatus for feeding, sheet
The disclosed feeding mechanism of invention can realize the purpose of equivalent charging, and this is simple in structure, low manufacture cost, practicability

Side-fed mechanism perforation connection, taper lower hopper is equipped in the lower section of the transition hopper, in the feed bin
Rotary shaft is connected along its length, and wherein one end of the rotary shaft is sequentially connected by main motor, is set in the rotary shaft
Set a circle swivelling chute.
Preferably, two side-fed mechanisms include side hopper, arc groove is equipped in the side hopper, in institute
It states and feed spool is set along its length in arc groove, feeding blade, and the two of the feed spool are respectively provided on the feed spool
End is arranged by bearing at the both ends of the side hopper.
Preferably, feed spool the same end of two side-fed mechanisms is between the driving end of the main motor
It is connected by belt transmission.
Preferably, also setting up row's taper feeding tooth on the feeding blade.
Preferably, the section of each swivelling chute is bowl structure.
Preferably, it is respectively provided with sealing counterpart one in each two groove wall top of the swivelling chute, and in the swivelling chute
Two cell walls on the inside of be all provided with the automatic open-close part that is magnetic.
It is matched with the sealing counterpart one preferably, being equipped in the two side walls bottom end of the taper lower hopper
Sealing counterpart two.
Preferably, the sealing counterpart one includes body groove with the sealing counterpart two and is arranged described
Row's ball in body groove.
Preferably, the magnetism automatic open-close part includes connecting plate and magnetic sheet, the connecting plate and the magnetism
It is connected by resetting spring between plate.
The beneficial effects of the invention are as follows:It is compared with prior art, of the invention to the improvement is that,
First, the present invention devises bowl-shape swivelling chute, and the setting sealing counterpart one on swivelling chute, taper lower hopper
Cell wall on setting sealing counterpart two, when each swivelling chute is rotated to the top of rotary shaft, at this time seal counterpart one
With sealing counterpart two, sealing cooperation, while biomass fuel pellet blanking from taper lower hopper, and fall into swivelling chute,
Because being contacted by ball between sealing counterpart one and sealing counterpart two, which can not only realize in blanking process
It is in sealing contact, and the two rear, lower full rear resistance of the swivelling chute into next position rotary course of material in sealing contact can also be reduced
The purpose of power, sealed set mainly prevents air from entering, reversed fired biomass particle;
Secondly, the present invention devises magnetic automatic open-close part, and the magnetic sheet of two magnetic automatic open-close parts is attracting, the magnetism
The purpose of automatic open-close part setting is to pass through the gravity of biomass fuel pellet when a swivelling chute is rotated to the top
Two magnetic sheets arranged in a crossed manner are opened, after the completion of the blanking in swivelling chute, when which needs to be rotated down, two phases
The magnetic sheet of suction is inhaled together automatically, realizes seal closure, in this way during the swivelling chute for filling fuel is rotated down just
Fuel leakage is not had, realizes the precision purpose of equivalent blanking;
Again, the present invention is in order to improve the uniform blanking of feed end, therefore two-way side-fed mechanism is arranged, and passes through
Feeding blade with taper feeding tooth carries out feeding, and material even drop down in side-fed mechanism can be ensured to transition
In hopper, and high degree of automation.
