Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, the anti-of biomass layer combustion boiler of the present invention flashes over isolating device, including feed hopper 1,
Burner hearth 2, fire grate 3, actuating unit, pulley mechanism 5 and isolating door 6, burner hearth 2 and feed hopper 1 are disposed adjacent, and fire grate 3 is arranged on stove
The fuel below thorax 2 and feed hopper 1 and falling feed hopper 1 is transported in burner hearth 2, and isolating door 6 is arranged on directly over fire grate 3,
And be located between feed hopper 1 and burner hearth 2, actuating unit is arranged on the side away from burner hearth 2 for the feed hopper 1, and pulley mechanism 5 includes sliding
Wheel group and pull rope 53, described pull rope 53 bypasses described assembly pulley, one end of described pull rope 53 and the output of actuating unit
End connects, and the other end is connected with described isolating door 6.Biomass layer combustion boiler of the present invention anti-flash over isolating device can by fuel with
Passageway break between burner hearth 2, prevents from closing boiler post fuel effusion escaping gas enter burner hearth 2 and draw under waste heat effect
Send out and flash over, cause security incident.
Wherein, one end of pull rope 53 is connected with actuating unit by rotating shaft 7, assembly pulley include the first fixed pulley 51,
Two fixed pulleys 52, the first fixed pulley 51 and the second fixed pulley 52 are arranged between feed hopper 1 and burner hearth 2, the first fixed pulley 51
It is arranged on the top of the second fixed pulley 52, pull rope 53 bypasses the first fixed pulley 51 and the second fixed pulley 52 successively.
Wherein, the width of the width ratio fire grate 3 of isolating door 6 is big, between the aspect ratio fire grate 3 of isolating door 6 and burner hearth 2 between
Away from exceeding 20%, stop that fuel enters burner hearth 2, the section of isolating door 6 is wedge shape, and isolating door 6 is close to stove near the one side of burner hearth
The outer wall of thorax 2, isolating door 6 smoothly can fall on fire grate 3 along the outer wall of burner hearth 2, and by the passage between fuel and burner hearth 2
Fully separate.
Wherein, the present invention prevents flashing over isolating device and also including striker plate 4, striker plate 4 be arranged on feed hopper 1 and fire grate 3 it
Between, striker plate 4 is fixed on pull rope 53, is interaction relation, will feed when isolating door 6 falls between striker plate 4 and isolating door 6
Bucket 1 and burner hearth 2 between passageway break when, striker plate 4 also towards the direction movement of feed hopper 1 by feed hopper 1 close prevention combustion
Material is fallen on fire grate 3；When starting actuating unit, in the presence of pulley mechanism, striker plate 4 moves towards the direction of actuating unit
Charging aperture is opened, 6 shifting on isolating door simultaneously, fuel can enter burner hearth 2 and burn, easy and simple to handle.
It is provided with sliding rail 8, striker plate 4 is arranged on sliding rail 8, sliding rail 8 between feed hopper 1 and fire grate 3
Both sides be provided with pilot hole 81, striker plate 4 is provided with gim peg 41, described pilot hole is inserted at the two ends of gim peg 41 respectively
In 81, when striker plate 4 moves to one end of sliding rail 8, gim peg 41 can be stuck in pilot hole 81 end and limit striker plate 4
Continue to move to.
Wherein, striker plate 4 is longer than described charging aperture by 10% 20%, and after so starting actuating unit, fuel will not be at once
Fall, the time of leaving starts fire grate 3, prevent from fuel from piling up on fire grate 3 causing burning insufficient.
Wherein, it is additionally provided with ventilation apparatus in burner hearth, ventilation apparatus provide enough oxygen for fuel combustion, and permissible
Fuel gas in burner hearth 2 is dispelled, prevents from further flashing over phenomenon generation.
The anti-use process flashing over isolating device of biomass layer combustion boiler of the present invention is as follows：
During starting trouble, first start ventilation apparatus, ventilation apparatus first run 5 minutes, start inside burner hearth 2 to divulge information, blow away
Remain in the fuel gas of boiler internal, then start actuating unit, motor rotation drives rotating shaft 7 to rotate, rotating shaft 7 rotates and drives
Pulley mechanism 5 runs, and striker plate 4 slides along sliding rail 8 to actuating unit direction, because the length of striker plate 4 is than charging
Mouthful length length 10% 20%, fuel does not temporarily fall out, and isolating door 6 is raised above with the operation of pulley mechanism 5, tightly
Then start fire grate 3, the fuel on fire grate 3 to burner hearth 2 internal motion, is then heated and burns with fire grate 3, when striker plate 4 moves
Move sliding rail 8 end when, gim peg 41 be stuck in pilot hole 81 end limit striker plate 4 continue to move to.
When closing boiler, first disconnect the switch of actuating unit, isolating door 6 declines under self gravitation effect, and drives gear
Flitch 4 towards feed hopper 1 direction move, charging aperture is closed, isolating door 6 along burner hearth 2 outer wall fall and with fire grate 3 table
Face contacts, and the passageway break between fuel and burner hearth 2 prevents fuel from escaping escaping gas under waste heat effect and being gathered in
Cause in burner hearth 2 and flash over it is ensured that safety, and then close fire grate 3, after then ventilation apparatus time delay runs more than 10 minutes
Close, dispel fuel gas in stove, boiler is out of service.
Finally it should be noted that：These are only the preferred embodiments of the present invention, be not limited to the present invention, although
With reference to embodiment, the present invention is described in detail, for a person skilled in the art, it still can be to aforementioned
Technical scheme described in each embodiment is modified, or carries out equivalent to wherein some technical characteristics, but all
