Abstract
The utility model is protected on front side of a kind of circulating fluid bed boiler and is mixed coal bunker, its upper strata is the rectangle storehouse of ferro-concrete material and steel, upper strata cross-sectional plane is rectangle, lower floor is the hyperbola storehouse of steel, and lower floor vertical section is hyperbola, each storehouse inner liner stainless steel plate or micro-crystal plate, it is characterized in that: at the middle and upper levels for the rectangle of steel is to round platform gradual change storehouse, cross-sectional plane is truncated cone-shaped at the middle and upper levels, middle lower floor be the round platform of steel to circular gradual change storehouse, middle lower floor and lower floor's cross-sectional plane are circular; Two identical coal bunkers are one group, and two equal Central Symmetries of coal bunker are arranged, upper strata, at the middle and upper levels, the line of centers of middle lower floor and lower floor's cross-sectional plane is coaxial.Advantage of the present utility model: one is owing to not having corner between rectangle to circle, can not overstock coal like this; Two is that the equal Central Symmetries of two coal bunkers are arranged, upper strata, at the middle and upper levels, the line of centers of middle lower floor and lower floor's cross-sectional plane is coaxial, does not offset.
Description
Technical field
The utility model relates to coal bunker on front side of circulating fluid bed boiler, is a kind of cement concrete possessing not chute blockage function-steel coal bunker for CFBB broken coal particle.
Background technology
CFBB requires that coal-fired granularity is not more than 13mm.Easily caking retained by the broken coal of particle diameter≤13mm in coal bunker, do not flow and result in blockage, overstock in coal bunker, make a big impact to normal production, the prior art slowing down broken coal caking generally adopts loosening machine even to adopt the method for air bubble, but fundamentally do not solve the flowing power of coal, coal-fired caking even hardens, and seriously hinders production run.
The novel coal bunker of Chinese patent CN 203143388 U thermal powerplant, coal bunker is made up of upper, middle and lower, and described upper cross section is rectangle, and described middle part is circumference joint, described lower cross section is circular or oval, and described lower vertical section is hyperbola.Its weak point one is that middle part adopts circumference joint, and have corner, namely have coal not allow runny region, two is the upper and lower line of centers disalignments of coal bunker, and towards side skew, coal bunker side and the minimum place of horizontal plane angle easily produce the immobilising region of coal.
Utility model content
The utility model aims to provide coal bunker on front side of a kind of circulating fluid bed boiler, and it can overcome the problems referred to above in prior art well, makes the good fluidity of coal, not chute blockage.
The utility model adopted technical scheme of will dealing with problems is: mix coal bunker on front side of circulating fluid bed boiler, upper strata is the rectangle storehouse of ferro-concrete material and steel, and upper strata cross-sectional plane is rectangle; Lower floor is the hyperbola storehouse of steel, and lower floor vertical section is hyperbola; Each storehouse inner liner stainless steel plate or micro-crystal plate.Be at the middle and upper levels the rectangle of steel to round platform gradual change storehouse, cross-sectional plane is truncated cone-shaped at the middle and upper levels; Middle lower floor be the round platform of steel to circular gradual change storehouse, middle lower floor and lower floor's cross-sectional plane are circular.
A CFBB generally needs the coal bunker that correspondence two is identical.Two identical coal bunkers are one group, and two equal Central Symmetries of coal bunker are arranged, upper strata, at the middle and upper levels, the line of centers of middle lower floor and lower floor's cross-sectional plane is coaxial.
Coal bunker side and horizontal plane angle are all greater than 65 °.
Upper strata is the rectangle storehouse of ferro-concrete material and steel, be that two rectangles are to round platform gradual change storehouse at the middle and upper levels, material is steel, and steel rectangle storehouse and steel round platform gradual change storehouse open end agree with, and the gradual change of the round platform at the middle and upper levels storehouse of steel, middle lower floor's round platform storehouse and lower floor's hyperbola storehouse are all agreed with.
Compared with prior art, on front side of the utility model circulating fluid bed boiler, the progressive part of coal bunker is: one be the utility model the middle level of prior art coal bunker is become at the middle and upper levels with middle lower floor, be that the rectangle of steel is to round platform gradual change storehouse at the middle and upper levels, cross-sectional plane is truncated cone-shaped at the middle and upper levels, middle lower floor is that the round platform of steel is to circular gradual change storehouse, middle lower floor and lower floor's cross-sectional plane are circular, owing to not having corner between rectangle to circle, can not overstock coal like this; Two is that the equal Central Symmetries of two coal bunkers are arranged, upper strata, at the middle and upper levels, the line of centers of middle lower floor and lower floor's cross-sectional plane is coaxial, does not offset.In addition, the upper strata rectangle of the utility model coal bunker can receive more coal, middle level truncated cone-shaped and circular coal lateral pressure less, lower floor's hyperbola can slow down coal stripper plate junction phenomena, makes coal have flowing power.

Detailed description of the invention
Example below in conjunction with accompanying drawing is described further utility model.
See accompanying drawing, coal bunker of the present utility model, is made up of upper strata 1, at the middle and upper levels 2, middle lower floor 3 and lower floor 4.Upper strata 1 is that the rectangle circle of contact arc angle of two long 5000mm, wide 3115mm, high 1970mm forms side by side; At the middle and upper levels 2 be two rectangles of high 2400mm to round platform gradual change storehouse, each rectangle agrees with one of them rectangle on upper strata 1 respectively to top, round platform gradual change storehouse, and each rectangle is to round platform gradual change storehouse retracted downward to round platform radius 1557.5mm, straight section 1885mm; Middle lower floor 3 is that two round platform gradual change storehouses of high 2600mm are to circular gradual change storehouse, each round platform gradual change storehouse to top, circular gradual change storehouse respectively with at the middle and upper levels 2 one of them round platform agree with, each round platform gradual change storehouse is to circular gradual change storehouse retracted downward to round diameter 3000mm; Lower floor 4 is two hyperbola storehouses of high 3200mm, and cross-sectional plane is circular, and vertical section is hyperbola; Lower floor 4 bottom opening diameter 1200mm, coal bunker side and horizontal plane angle are all greater than 65 °, ensure that coal bunker has enough large lower coal angle.During work, the bunker coal carried by coal supply belt (or other coal supply equipment) enters coal bunker from the open top coal dropping port on the upper strata 1 of coal bunker, sequentially pass through upper strata 1, at the middle and upper levels 2, middle lower floor 3 and lower floor 4, fall from the opening of hyperbola bottom is smooth and easy.
