Description
Technical field
The utility model relates to the biomass energy development field, particularly a kind of biomass power generation even feeding and prevent that burner hearth from returning cigarette, tempering, the novel dispenser that the prevention feed stops up.
Background technology
The biological energy source generation technology developed comparatively fast in recent years in China, and in the biomass electric power plant that has built up, ubiquity returns difficult problems such as cigarette, tempering, obstruction.The feed bin biomass fuel is sent into feed opening by conveyer, slips into the boiler hearth of circulating fluidized bed burning then.Burner hearth normally operates to the negative pressure operation, because the diversity of biomass fuel, pressure-fired or operation under positive pressure often appear in factors such as water-in-fuel, the soil amount of containing exceed standard, flue gas, naked light anti-channeling enter feeding system, there are than conflagration hidden danger feed bin in flue gas, naked light along blanking channel play up always, and the working environment of feeding system is polluted simultaneously, therefore how to realize even feeding and prevent flue gas, naked light anti-channeling effectively, closely become a key technology of biomass power generation industry.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art and a kind of novel structure is provided, and is with low cost, the living beings Smoke proofing and fire proofing dispenser that reliability is high.
The purpose of this utility model is achieved by following technical proposals:
A kind of living beings Smoke proofing and fire proofing dispenser, comprise casing, impeller, line shaft, adjusting arc plate, bearing block, actuating unit, described impeller is fixed on the described line shaft, described line shaft is installed on the described bearing block by bearing, described bearing block is fixed on the support, described actuating unit is connected with described line shaft, the described adjusting arc plate and the arm of force fix on the described casing by hinges fixing, balancing weight has been hung in described arm of force end, described actuating unit counterclockwise rotates by the line shaft impeller, regulates the arc plate and contacts with impeller under the balancing weight effect.
In the utility model, the adjusting arc plate side of described casing is equipped with pressure alarm, when regulating the arc plate and bear pressure greater than the reaction torque power of balancing weight with the starting pressure alarm.
In the utility model, the two ends of described line shaft are by sealing ring, and described sealing ring is fixed on the described casing.
The utility model has following advantage owing to adopt technique scheme:
1, adopts the continuous rotation of impeller to realize continuous-feeding, can realize even feeding, prevent from that flue gas, naked light from playing a reversed role to enter feed bin.
2, regulate the effect of arc plate and counterweight, can be good at strengthening impeller seals,, regulate arc plate Free up Memory backward, prevent that impeller is stuck by biomass fuel in case there is biomass fuel to be stuck in the left side of impeller.
3, regulate arc plate and pressure alarm acting in conjunction, in case a large amount of biomass fuels blocks impeller, pressure alarm can be reported to the police timely, prevents the generation of dangerous situation, makes living beings Smoke proofing and fire proofing dispenser feed process more safe and reliable.
In sum, described utility model---living beings Smoke proofing and fire proofing dispenser has novel structure, and is with low cost, can prevent reliably that burner hearth is to biomass silo play a reversed role flue gas and naked light, realize that even feeding and prevention blanking channel stop up, and are suitable for biomass electric power plant and promote the use of.

Among the accompanying drawing 1-2: 1---charging aperture, 2---impeller, 3---line shaft, 4---feed opening, 5---regulate arc plate, 6---pressure alarm, 7---casing, 8---hinge, the 9---arm of force, 10---balancing weight, 11---bearing block, 12---support, 13---sealing ring, 14---actuating unit.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of open-birth material Smoke proofing and fire proofing dispenser.
Shown in Fig. 1 to 2, a kind of living beings Smoke proofing and fire proofing dispenser, comprise casing 7, impeller 2, line shaft 3, regulate arc plate 5, bearing block 11, actuating unit 14, described impeller 2 is fixed on the described line shaft 3, described line shaft 3 is installed on the described bearing block 11 by bearing, and described bearing block 11 is fixed on the support 12, and described actuating unit 14 is connected with described line shaft 3, the described adjusting arc plate 5 and the arm of force 9 are fixed on the described casing 7 by hinge 8, and balancing weight 10 has been hung in the described arm of force 9 ends.Described actuating unit 14 counterclockwise rotates by line shaft 3 impeller 2, regulates arc plate 5 and contacts with impeller 2 under balancing weight 10 effects.
In the utility model, adjusting arc plate 5 sides of described casing 7 are equipped with pressure alarm 6, when regulating arc plate 5 and bear pressure greater than the reaction torque power of balancing weight 10 with the starting pressure alarm.
In the utility model, the two ends of described line shaft 3 are by sealing ring 13, and described sealing ring 13 is fixed on the described casing 7.
When biomass fuel falls on the impeller 2 by charging aperture 1 from the feed bin material inlet, under the counter clockwise direction of impeller 2 is rotated, biomass fuel is pushed downwards, slip into the burner hearth burning from feed opening 4.Regulate arc plate 5 make fuel under push away process and keep suitably tight power, effectively stop flue gas, naked light upwards to be played a reversed role.Occur the jam impeller easily when the biomass fuel fragmentation quality is relatively poor, agglomerating, regulates arc plate 5 Free up Memory backward when jam, touch the pressure alarm warning and stop feed, wait for that the staff handles, effectively pre-anti-clogging is to the damage of equipment.
