Abstract
The invention discloses an improved structure of a raw coal cabin of a circulating fluidized bed boiler. The improved structure comprises the raw coal cabin provided with a material inlet and a material outlet, wherein the raw coal cabin is a cone-shaped and double-curve-shaped cabin body, and the intersection angle between the horizontal plane and the front wall of the raw coal cabin is greater than or equal to 70 degrees. The improved structure of the raw coal cabin of the circulating fluidized bed boiler has the advantages that due to the structural design, the coal blockage problem of fault coal is solved, the coal falling effect is good, and the improved structure can perfectly adapt to raw coal with the moisture content being 8 percent to 9 percent.
Description
Technical field
The present invention relates to run coal bin building technology field, relate 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.
Summary of the invention
Because the above-mentioned defective of prior art, technical problem to be solved by this invention 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 invention 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 invention has the beneficial effects as follows:
The improvement structure of CFBB run coal bin of the present invention 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 of the present invention, concrete structure and generation is described further, to understand the object of the invention, characteristic and effect fully.

Fig. 2 is the left TV structure sketch map of Fig. 1.
Fig. 3 is the structural representation of the present invention's 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 CFBB run coal bin of the present invention 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.
Among the present invention, run coal bin 1 also is provided with balance wind apparatus (not shown), to take off power on the balance feeder.
Further, among the present invention, 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 among the present invention.
The improvement structure of CFBB run coal bin of the present invention, 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 preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can design according to the present invention make many modifications and variation.Therefore, all technical staff in the art all should be in the determined protection domain by claims under this invention's idea on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment.
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.
