Abstract
The utility model discloses an improved structure of a raw coal bunker of a circulating fluidized bed boiler. The improved structure comprises the raw coal bunker provided with a feeding hole and a discharge hole; the raw coal bunker is a conical double-curved bunker; and the crossing angle of the front wall of the raw coal bunker and the level is more than or equal to 70 degrees. The improved structure of the raw coal bunker of the circulating fluidized bed boiler solves the problem of blockage of inferior coal, has a good coal falling effect, and can well adapt to raw coal of which the moisture content is 8 to 9 percent.
Description
Technical field
The utility model relates to run coal bin building technology field, relates in particular to a kind of improvement structure of CFBB run coal bin.
Background technology
Like Fig. 1, shown in Figure 2, existing a kind of run coal bin structure has a big feeding mouth 12 and a little discharging opening 11, adopts tapered warehouse, and little coal bunker adopts tube connector to be connected with feeder.Discharging opening 11 sizes of run coal bin 1 are about 630 millimeters * 1000 millimeters, and the front wall 13 of run coal bin 1 is roughly 60 ° with the angle of cut of horizontal plane.In addition, also be provided with the loose machine that is used for loose raw coal in the run coal bin 1.For preventing that the boiler hot flue gas from pouring in down a chimney, only adopted a cold wind to seal.
But in actual use, above run coal bin structure when being applied to fuel and being the higher colm of water content, in the run coal bin 1 through regular meeting chute blockage takes place, bulkhead is hung abnormalities such as coal.This has not only increased operations staff's workload, and more serious is the safe and stable operation that jeopardizes the boiler unit.
Therefore, those skilled in the art is devoted to develop that a kind of coal breakage is effective, the improvement structure of not susceptible to plugging CFBB run coal bin.
The utility model content
Because the above-mentioned defective of prior art, the utility model technical problem to be solved provides a kind of improvement structure of simple in structure, CFBB run coal bin that cost is low.
Be to realize above-mentioned purpose, the utility model provides a kind of improvement structure of CFBB run coal bin, comprise have a feeding mouth, the run coal bin of a discharging opening; Said run coal bin is that taper adds the hyperbola warehouse; The front wall of said run coal bin and the horizontal angle of cut are more than or equal to 70 °.
Preferably, said run coal bin also is provided with the balance wind apparatus.
Preferably, the liner of said run coal bin is highdensity macromolecule sheet material.
The beneficial effect of the utility model is:
The improvement structure of the CFBB run coal bin of the utility model because said structure design, has solved the chute blockage problem of colm, and coal breakage is effective, all can well adapt to for the raw coal of moisture 8%～9%.
Below will combine accompanying drawing that the technique effect of design, concrete structure and the generation of the utility model is described further, with purpose, characteristic and the effect of understanding the utility model fully.

Fig. 1 is the structural representation of a kind of run coal bin in the prior art.
Fig. 2 is the left TV structure sketch map of Fig. 1.
Fig. 3 is the structural representation of the utility model one specific embodiment.
Fig. 4 is the left TV structure sketch map of Fig. 3.
The specific embodiment
Like Fig. 3, shown in Figure 4, improvement structure one specific embodiment of the CFBB run coal bin of the utility model comprises the run coal bin 1 with a feeding mouth 12, a discharging opening 11.Discharging opening 11 is of a size of 630 millimeters * 1600 millimeters.
Run coal bin 1 adds the hyperbola warehouse for taper, particularly, is formed by connecting a double curve shape section 14 and a conical section 15.
In the present embodiment, the liner of run coal bin 1 is highdensity macromolecule sheet material, and the front wall 13 of run coal bin 1 and the horizontal angle of cut reduce the frictional resistance of front wall 13 more than or equal to 70 °, helps raw coal and in run coal bin 1, falls smoothly.
In the utility model, run coal bin 1 also is provided with balance wind apparatus (not shown), to take off power on the balance feeder.
Further, in the utility model, also cancelled loose machine in the run coal bin 1, cancelled the tube connector of little coal bunker and feeder, made little coal bunker into old name for the Arabian countries in the Middle East ground circle and directly link to each other with feeder.The structure that more than is provided with originally as existing, repeats no more in the utility model.
The improvement structure of the CFBB run coal bin of the utility model, because said structure design when simplifying the run coal bin structure, has solved the chute blockage problem of colm, coal breakage is effective, all can well adapt to for the raw coal of moisture 8%～9%.
More than describe the preferred embodiment of the utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technical staff in the art according to the design of the utility model on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in determined protection domain by claims.
Claims (3)
1. the improvement structure of a CFBB run coal bin, comprise have a feeding mouth, the run coal bin of a discharging opening; It is characterized in that: said run coal bin is that taper adds the hyperbola warehouse; The front wall of said run coal bin and the horizontal angle of cut are more than or equal to 70 °.
2. the improvement structure of CFBB run coal bin as claimed in claim 1 is characterized in that: said run coal bin also is provided with the balance wind apparatus.
