Abstract
The utility model discloses an anti-blocking coal bunker of a boiler coal feeder. The anti-blocking coal bunker comprises a coal feeding bin (1), a transition bin (2) and a coal falling bin (3), wherein the coal feeding bin is inverted-frustum-shaped; a lower opening of the coal feeding bin (1) is connected with an opening of the transition bin (2) through a transition bin ring (4); the section of the upper opening of the transition bin (2) is larger than that of the lower opening of the coal feeding bin (1); a lower opening of the transition bin (2) is connected with an upper opening of the coal falling bin (3) through a coal falling bin ring (5); the section of the upper opening of the coal falling bin (3) is larger than that of a lower opening of the transition bin (2). Coal is loosened through a multi-layer expansion type bunker body structure, the overall flowing property of the coal bunker is improved, the pressure of a high-fall coal seam to the lower opening of the coal bunker is reduced, and the problems of coal blockage and caking are solved.
Description
Technical field
the utility model relates to coal bunker, is specifically related to the Anti Plugging Bunker of coal feeder of boiler.
Background technology
Every boiler of 350MW generator set has 5 coal bunkers, the corresponding weighing coal feeder of each coal bunker, existing coal bunker is hyperbola form coal bunker, coal bunker bottom caliber size sharply changes and dwindles, and there are a plurality of adapter flange combinations, volume is large, diameter greatly, highly long coal bunker causes raw coal to flow slowly, ature of coal particle is little, just easily cause and be bonded to piece during high humidity, bottom coal dust pressurized seriously bonds, raw coal after bonding does not flow and then the canopy coal that hardens for a long time, particularly mixes burning mud coal and faulty coal and more easily causes coal bunker chute blockage.
Summary of the invention
The purpose of this utility model is: a kind of Anti Plugging Bunker of coal feeder of boiler is provided, by multilayer expanding type warehouse structure, ature of coal loosened,
Improve coal bunker overall flow performance, reduce the pressure of high drop coal seam to coal bunker end opening, solve chute blockage, canopy coal problem.
Technical solution of the present utility model is: this Anti Plugging Bunker comprise be inversed taper platform shape enter coal bunker, transitional storehouse and coal breakage storehouse, the end opening that enters coal bunker connects the suitable for reading of transitional storehouse through transitional storehouse annulus, the cross section suitable for reading of transitional storehouse is greater than the end opening cross section into coal bunker, the end opening of transitional storehouse connects the suitable for reading of coal breakage storehouse through coal breakage storehouse annulus, and the cross section suitable for reading in coal breakage storehouse is greater than the end opening cross section of transitional storehouse.
Wherein, on transitional storehouse annulus, around coal bunker, divide equally and arrange four and smash coal hole, aperture is 120mm, smashes and on coal hole, is furnished with quick hermatic door.
Wherein, the top of transitional storehouse and around circumference, four pressurized air purge nozzle are installed respectively apart from 1 meter of of end opening, purge nozzle is 90 ° of layouts, nozzle latus rectum DN10mm.
Wherein, three hopper wall vibrators are installed on transitional storehouse, between vibrator, are mutually hexagonal angle and arrange.
Wherein, enter on coal bunker two hopper wall vibrators are installed, between vibrator, be mutually 180 ° of angles and arrange.
The utlity model has following advantage: 1, the cross section suitable for reading of transitional storehouse is greater than the end opening cross section into coal bunker, the cross section suitable for reading in coal breakage storehouse is greater than the end opening cross section of transitional storehouse, dilatation is loose step by step to make coal bunker, reduces the pressure under coal bunker diff-H, thereby reduces friction and harden situation; 2, on transitional storehouse annulus, around coal bunker, divide equally and arrange four and smash coal hole, be convenient to clear coal in service; 3, the top of transitional storehouse and around circumference, four pressurized air purge nozzle are installed respectively apart from 1 meter of of end opening, increases coal bunker loose function automatically; 4, enter on coal bunker and transitional storehouse hopper wall vibrator is installed, improve coal bunker overall flow performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 enters coal bunker, 2 transitional storehouses, 3 coal breakage storehouses, 4 transitional storehouse annulus, 5 coal breakage storehouse annulus, 6 smash coal hole, 7 purge nozzle, 8 transitional storehouse hopper wall vibrators, 9 enter coal bunker wall vibrator.
The specific embodiment
As shown in Figure 1, this Anti Plugging Bunker comprise be inversed taper platform shape enter coal bunker 1, transitional storehouse 2 and coal breakage storehouse 3, the end opening that enters coal bunker 1 connects the suitable for reading of transitional storehouse 2 through transitional storehouse annulus 4, the cross section suitable for reading of transitional storehouse 2 is greater than the end opening cross section into coal bunker 1, the end opening of transitional storehouse 2 connects the suitable for reading of coal breakage storehouse 3 through coal breakage storehouse annulus 5, and the cross section suitable for reading in coal breakage storehouse 3 is greater than the end opening cross section of transitional storehouse 2.
Wherein, on transitional storehouse annulus 4, around coal bunker, divide equally and arrange four and smash coal hole 6, aperture is 120mm, smashes and on coal hole, is furnished with quick hermatic door.
Wherein, the top of transitional storehouse 2 and around circumference, four pressurized air purge nozzle 7 are installed respectively apart from 1 meter of of end opening, purge nozzle is 90 ° of layouts, nozzle latus rectum DN10mm.
Wherein, three transitional storehouse hopper wall vibrators 8 are installed on transitional storehouse 2, between vibrator, are mutually hexagonal angle and arrange.
Wherein, enter on coal bunker 1, to install two and enter coal bunker wall vibrator 9, between vibrator, be mutually 180 ° of angles and arrange.
