Description
Technical field
It the utility model is related to fluidized-bed combustion boiler technical field, more particularly to a kind of anti-blocking raw coal bucket of fluidized-bed combustion boiler.
Background technology
At present, the chute blockage phenomenon of the raw coal hopper of fluidized-bed combustion boiler happens occasionally, and raw coal is entering the coal of fluidized-bed combustion boiler
After bucket, raw coal bulk is more, and coal bunker sectional area constantly shrinks, and the frictional force and extruding force closer to lower coal oral area position are bigger,
It is not smooth or even block to easily cause lower coal, has a strong impact on the normal operation of equipment, while also improve the fault rate of equipment, increases
Maintenance cost is added.
Utility model content
In view of the shortcomings of the prior art, a kind of blanking of the utility model offer is smooth, it is broken that block raw coal can be carried out
The anti-blocking raw coal bucket of fluidized-bed combustion boiler.
Technical scheme is used by the utility model solves its technical problem：The anti-blocking raw coal bucket bag of fluidized-bed combustion boiler
Including feed hopper, the feed hopper is a sidewalls vertical, the oblique outer tetrahedral structure of the relative inclined charging aperture of another side wall,
Breaker is provided with the feed hopper, the breaker includes determining jaw, moving jaw plate, eccentric wheel, motor, described fixed
Jaw is fixed on the vertical wall of feed hopper, and the moving jaw plate is installed on the inclined wall of feed hopper by spring, and the eccentric wheel is set
Driven below the moving jaw plate by the motor.
In a kind of preferred embodiment of the anti-blocking raw coal bucket of fluidized-bed combustion boiler provided by the utility model, the feed hopper
Bottom side is provided with discharging opening, and the discharging opening is provided with discharge screw feeder.
In a kind of preferred embodiment of the anti-blocking raw coal bucket of fluidized-bed combustion boiler provided by the utility model, the feed hopper
Inclined wall top is additionally provided with protective plate.
In a kind of preferred embodiment of the anti-blocking raw coal bucket of fluidized-bed combustion boiler provided by the utility model, the motor
It is also associated with frequency converter.
Compared with prior art, the beneficial effect of the anti-blocking raw coal bucket of fluidized-bed combustion boiler provided by the utility model is：This reality
With new by setting a breaker in the feed hopper, moving jaw plate is driven using motor driving eccentric wheel, makes jaw
Plate is extruded raw coal with determining jaw, and the raw coal of bulk is crushed, while can also reach the purpose of broken arch, prevents raw coal from blocking
Feed hopper；The discharge screw feeder that the discharging opening is provided with, discharging is rapid, avoids the blocking of feed hopper bottom.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Other accompanying drawings are obtained, wherein：

Referring to Fig. 1, the anti-blocking raw coal bucket 1 of fluidized-bed combustion boiler includes feed hopper 11, the feed hopper 11 is a side wall
Vertically, the oblique outer tetrahedral structure of the relative inclined charging aperture of another side wall, the feed hopper 11 is interior to be provided with breaker,
The breaker includes determining jaw 12, moving jaw plate 13, eccentric wheel 14, motor 15, described to determine jaw 12 and be fixed on charging
The vertical wall of bucket 11, the moving jaw plate 13 are installed on the inclined wall of feed hopper 11 by spring 16, and the eccentric wheel 14 is located at institute
The lower section of moving jaw plate 13 is stated to be driven by the motor 15.
Further, the bottom side of the feed hopper 11 is provided with discharging opening 112, and the discharging opening 112 stirs provided with discharge
Dragon 17, discharge is rapid, anti-blocking.
Further, the inclined wall top of the feed hopper 11 is additionally provided with protective plate 18, prevents raw coal from entering the dynamic jaw
The lower section of plate 13, avoids moving jaw plate 12 from blocking.
Further, the motor 15 is also associated with frequency converter 19, can reach frequency control by frequency converter 19
Purpose.
The beneficial effect of the anti-blocking raw coal bucket 1 of fluidized-bed combustion boiler provided by the utility model is：The utility model passes through in institute
State and a breaker set in feed hopper 11, using motor 15 drive eccentric wheel 14 drive moving jaw plate 13, make moving jaw plate 13 with
Determine jaw 12 to extrude raw coal, the raw coal of bulk crushed, while the purpose of broken arch can also be reached, prevent raw coal block into
Hopper；The discharge screw feeder 17 that the discharging opening 112 is provided with, discharging is rapid, avoids the blocking of the bottom of feed hopper 11.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
