Description
Technical field
The utility model relates to boiler plant technical field, particularly relates to a kind of biomass fuel boiler secondary feed arrangement.
Background technology
Biomass fuel is because the content of sulfur dioxide of producing after its burning is close to zero, and nitrogen oxide and dust content are extremely low, the dust of collection can also regard Fertilizer application, therefore, the toxic emission of biomass boiler is extremely low to environment, is the new forms of energy of a kind of low cost, environmental protection.The apparatus for feeding of biomass boiler, structurally larger difference is deposited with the apparatus for feeding of traditional coal-burning boiler, main cause is that biomass boiler adopts biological substance shaped granule as fuel, easily there is putty phenomenon when blanking in granular biomass molding fuel, and the granular fuel be transported on fire grate is easily deposited in a place, cause fuel insufficient, create black smoke, create environmental pollution, therefore, for putty and the uneven phenomenon of blanking, Chinese patent literature CN201706520U proposes solution, but, because boiler furnace is in burning running, tempering phenomenon can be there is, flare anti-channeling enters the passage of boiler feed equipment, unexpected burning is produced at passage place, if do not take measure to stop, fire alarm can be caused to occur, lead to fire incident.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of biomass fuel boiler secondary feed arrangement, its structure is simple, reasonable in design, effectively cut off burning things which may cause a fire disaster by secondary feeding manner, the biomass fuel preventing tempering from igniting in feeding warehouse, avoid the accidents such as fire and occur.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of biomass fuel boiler secondary feed arrangement, comprise feeding warehouse, it is characterized in that: below described feeding warehouse, be connected with one-level conveying mechanism, secondary conveying mechanism is connected with below described one-level conveying mechanism, described one-level conveying mechanism comprises the first material transfer chamber, described first inside, material transfer chamber is provided with the first helical axis, described first helical axis is connected with the first motor-driven by the first chain, described secondary conveying mechanism comprises the second material transfer chamber, described second inside, material transfer chamber is provided with the second helical axis, described second helical axis is connected with the second motor-driven by the second chain, described first motor is connected with electric control system with the second motor.
Further, be connected with above the front end of secondary conveying mechanism by connecting cylinder below the tail end of described one-level conveying mechanism.
Further, described first helical axis and the second helical axis are equipped with helical blade, and the direction of rotation of helical blade is consistent.
Further, described secondary conveying mechanism tail end is provided with the fixture suitable with boiler plant.
The beneficial effect adopting technique scheme to produce is: feeding warehouse of the present utility model is used for storing biomass fuel, after biomass fuel enters one-level feeding mechanism, first motor of one-level feeding mechanism is rotated by chain-driving first helical axis, by the helical blade in the first helical axis, biomass fuel is sent to the tail end of one-level feeding mechanism, secondary feeding mechanism front end inlet is sent to again through connecting cylinder, second motor of secondary feeding mechanism is rotated by the second chain-driving second helical axis, and by the helical blade in the second helical axis, biomass fuel is sent in combustion chamber, electric control system controls the rotation of the first motor and the second motor, when stopping feeding, first motor first stops operating, relative first motor of second motor has time delay, the fuel of secondary feeding mechanism all advances after in combustion chamber and stops operating by the second motor, thus effectively cut off burning things which may cause a fire disaster, prevent the biomass fuel that tempering is ignited in feeding warehouse, avoid the accidents such as fire to occur.
