The boiler feeding device
Technical field
The utility model relates to a kind of applied technical field of biomass molding fuel, especially a kind of boiler feeding device of biomass molding fuel.
Background technology
Generally indoor, the interior space is limited for biomass fuel boiler, requires the biomass fuel boiler feeding device to take up an area of and accomplishes as much as possible to minimize.
Present biomass fuel boiler feeding device uses single bucket elevator (see Fig. 1, this single bucket elevator is a small scall coal-fired boiler feeding device commonly used) usually.What single bucket elevator adopted is the intermittent movement mode, and when reinforced, hopper drops to lowest part, and workman's manual work is that hopper 1-4 ' is reinforced; During material loading, hopper 1-4 ' drives down at motor 1-1 ' and rises along guide rail 1-2 ' through pull rope 1-3 ', rise to certain altitude after, hopper 1-4 ' overturns material is unloaded to the stokehold feed bin of biomass fuel boiler.
Above-mentioned biomass fuel boiler feeding device is with forklift or load wagon fuel to be transported to boiler nearby, and reinforced with the artificial single bucket elevator hopper of giving again, labor intensity is big.
The utility model content
The purpose of the utility model just provides a kind of boiler feeding device, solves biomass fuel boiler material loading problem, reduces working strength of workers.
In order to reach above-mentioned purpose of design, the technical scheme that the utility model adopts is following:
A kind of boiler feeding device; Comprise single bucket elevator, storage bin, feeder, discharge bucket; Said single bucket elevator bottom is fixed on the ground; Said single bucket elevator one side is provided with the storage bin that is fixed on the ground, and the storage bin bottom is provided with feeder, and the feeder downside is provided with the corresponding discharge bucket of hopper of outlet and single bucket elevator.
Said feeder is double-spiral feeder or star-like discharger or jigging conveyer.
Said single bucket elevator mainly is made up of motor, guide rail, pull rope, hopper, and guide rail is fixed on the ground, guide rail top locking motor, and the guide rail bottom is provided with hopper, and the output axle head of said motor connects pull rope, and the pull rope bottom is connected hopper.
The beneficial effect of the described boiler feeding device of the utility model is: the secondary automatic charging, reduced working strength of workers, and the space there is not harmful effect basically; The utility model is will be under the prerequisite of the efficient that does not reduce boiler, on the basis of wasting space not, realizes the automatic charging function, reduces working strength of workers.
Storage bin can store the biomass compact forming fuel of some volumes, and the size of its concrete volume confirms that according to actual conditions the volume of general storage bin is equivalent to the several times of single bucket elevator bucket capacity.After placing storage bin, can filled biomass matter compact formed fuel in the storage bin, can also pile up biomass compact forming fuel on it, so storage bin does not have harmful effect basically to the stacking space of biomass compact forming fuel.In the practical work process, use load wagon to fill a biomass compact forming fuel, can supply the single bucket elevator hopper to come and go for several times to storage bin.
The double-spiral feeder major function is exactly in order to control storage bin endogenous substance compact formed fuel load, can guarantee under the situation that normal double-spiral feeder do not start, and double-spiral feeder must not discharging; When double-spiral feeder started, the biomass compact forming fuel in the storage bin was realized evenly, discharging quantitatively.Adopting double-spiral feeder is exactly even at discharge bucket width top discharge in order to realize material as its purpose of drawing mechanism of biomass fuel boiler feeding device, and this function also can realize through other structures.
The base plate of discharge bucket makes the biomass compact forming fuel that flows out in the drawing mechanism quicken, and makes biomass compact forming fuel possess certain speed slipping the exit of materials device, skids off with the parabolic path to the front lower place.
The hopper of single bucket elevator receives the biomass compact forming fuel of being gone out by discharge bucket, and to the regular hour, hopper fills, and lifting thereafter, discharging, reduces to original position.Entire work process can realize automatic control, and circulation is carried out.

Fig. 2 is the sketch map of the described boiler feeding device of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the optimum implementation of the utility model is done further detailed description.
As shown in Figure 2, the described boiler feeding device of the utility model embodiment divides secondary to realize the automation of biomass fuel boiler material loading; Complete equipment comprises single bucket elevator 1, storage bin 2, feeder 3, discharge bucket 4, and said single bucket elevator 1 bottom is fixed on the ground 5, and single bucket elevator 1 mainly is made up of motor 1-1, guide rail 1-2, pull rope 1-3, hopper 1-4; Guide rail 1-2 vertically is fixed on the ground 5; Guide rail 1-2 top locking motor 1-1, guide rail 1-2 bottom is provided with hopper 1-4, and hopper 1-4 can move up and down along guide rail 1-2; The output axle head of said motor 1-1 connects pull rope 1-3; Pull rope 1-3 bottom is connected on the hopper 1-4, behind the actuating motor 1-1, can drive hopper 1-4 through pull rope 1-3 and move up and down along guide rail 1-2; Said single bucket elevator 1 one sides are provided with the storage bin 2 that is fixed on the ground 5; Can store large number of biological matter compact formed fuel in the storage bin 2; Storage bin 2 bottoms are provided with feeder 3; Feeder 3 downsides are provided with the relative discharge bucket 4 of hopper 1-4 of outlet and single bucket elevator 1, and the raw materials during use in the storage bin 2 are exported through feeder 3, and directly and fast deliver to hopper 1-4 through discharge bucket 4 and carry out material loading.
Said feeder 3 is a double-spiral feeder.
The course of work is:
1. be that storage bin adds biomass compact forming fuel with machinery or manual type, feeding quantity is looked actual conditions and is decided.
Double-spiral feeder evenly, quantitative discharging.
3. biomass compact forming fuel is skidded off by discharge bucket.
4. the hopper of single bucket elevator receives the biomass compact forming fuel that is skidded off by discharge bucket.
5. double-spiral feeder stops feed.
6. the single bucket elevator hopper rises along guide rail.
7. single bucket elevator hopper upset, discharging.
8. the single bucket elevator hopper descends, homing.
The time interval between the open and close of said double-spiral feeder 3 is confirmed by the character of actual material.
Entire work process can distribute to control step by step and realize, also can realize through automatic control system.
Said feeding device can horizontal discharging, also discharging obliquely.
The feeder of the utility model is if use improved star-like discharger or jigging conveyer also can reach same effect.
The preferred embodiment of this specific embodiment the utility model can not limit the utility model, and concrete each item rights protection scope is defined by the claims.
