The utility model has the advantages of the showing of thickness automatically regulated air distribution volume of fuel is gone up according to traveling grate stoker.
Description
Technical field:
The utility model relates to a kind of boiler combustion air distribution technology, particularly a kind of biomass boiler traveling-grate stoker automatic Air Adjusting mechanism.
Background technology:
Existing biomass boiler traveling-grate stoker air distribution be adjusted to manual adjustment.Due to the difference of the ratio of briquetting of biomass molding fuel, the difference of content of ashes and calorific value etc., its burning velocity changes greatly, cause the number of times of damper and frequency large, manually be difficult to, undesirable due to air distribution, cause biomass combustion efficiency not high, in flue gas, oxygen content is higher, causes smoke pollution of boiler thing to discharge reduced value and exceeds standard.
Summary of the invention:
The utility model object is to provide a kind of biomass boiler traveling-grate stoker automatic Air Adjusting mechanism that a kind of thickness according to the living beings on traveling-grate stoker regulates air quantity automatically.
The technical scheme realizing the utility model object is, a kind of biomass boiler traveling-grate stoker automatic Air Adjusting mechanism, comprise fire grate, wind chamber and air door, it is characterized in that: the top of described fire grate is provided with detecting plate, the inner of detection axis is connected with the top of described detecting plate, in a plate hole of described detection axis rotational support on body of heater, the other end of described detection axis is connected with potentiometer, and described potentiometer is electrically connected with servomotor, the below of described fire grate is transversely evenly equipped with mutual disconnected wind chamber, the side in each wind chamber is provided with longitudinal baffle, wind chamber is divided into air channel and wind chamber, described longitudinal baffle is distributed with air port, middle air port is minimum, increased gradually by point mouth at middle air port to two ends, the front and back side plate in described air channel is respectively equipped with circular air inlet, it is relative with the circular port on described side plate that air intake plate is provided with two symmetrical scallop holes, described air intake plate and side plate are spirally connected, axis of rotation is supported in the hole on described air intake plate between two scallop holes, described rotating shaft is provided with two symmetrical fanning strips, the inner surface of this fanning strip and the outer surface of described air intake plate are slided and are joined, fanning strip in described rotating shaft is greater than the scallop hole on air intake plate.
The utility model has the remarkable advantage automatically regulating air distribution amount according to the thickness of fuel on traveling-grate stoker compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model; Fig. 2 is the A-A sectional view of Fig. 1; Fig. 3 is the full open mode schematic diagram of air intake plate fresh air inlet; Fig. 4 is air intake plate fresh air inlet full closing state schematic diagram, and Fig. 5 is that air intake plate fresh air inlet partially opens view.
Detailed description of the invention:
As shown in Figure 1-2, the utility model has following embodiment, in order to the thickness of feed layer realizing the biomass fuel on traveling-grate stoker on diverse location is different, need to provide different air distribution amounts, thus realize sufficient combustion efficiency, the below of fire grate 1 transversely arranges multiple wind chamber mutually closed for this reason, the left end in each wind chamber is provided with baffle plate, air channel 4 is formed between the left plate in this baffle plate and wind chamber, baffle plate is longitudinally evenly equipped with fresh air inlet 7, middle air holes is little, increased gradually (see Fig. 2) to rear and front end by centre, before each air channel, back side panel is respectively provided with an aerofoil 3, this air intake plate has two symmetrical scallop holes 11.Relative with the circular port on side plate, the diameter of this circular port is not more than the diameter of two scallop holes on described air intake plate, rotating shaft 8 is rotatably supported in the hole between air intake plate two scallop holes, this rotating shaft is respectively equipped with two symmetrical fanning strips 10, this fanning strip is greater than the scallop hole on air intake plate and joins with air intake plate outer surface is sliding, and described air intake plate is screwed on the side plate in air channel.One end of described rotating shaft is connected with servomotor 9 axle; Fuel bed depth detecting plate 5 is provided with above fire grate, the top of this detecting plate is connected with detection axis 6, described detection axis rotational support is in a plate hole of fire grate side, and the outer end of described detection axis is connected with potentiometer 2, and this potentiometer is electrically connected with described servomotor.
Operation principle of the present utility model, detecting plate original state (i.e. hang) is inanimate object matter fuel on fire grate, the unlatching size of the air inlet below fire grate is closed condition, when material bed thickness increases, material makes detecting plate deflect an angle, potentiometer is driven to rotate an angle, servomotor turns an angle, air door corresponding rotation one angle open mode, along with the increasing of fuel depth, detecting plate deflection angle increases, potentiometer angle of rotation is driven to increase, servomotor rotational angle increases, and intake increases thereupon, realizes the function automatically regulating air distribution amount.
