Abstract
A non-blockage deformed coal bunker comprises an upper bunker, a reducing bunker, a hyperbolical bunker, a seal structure and a deformed hopper from top to bottom. The upper bunker is in an upright tubular or upright rectangular structure. An upper opening of the reducing bunker is connected with the upper bunker, and a lower opening of the reducing bunker is connected with the hyperbolical bunker. The wall surface of the hyperbolical bunker deforms downwardly in componential curve forms, and the angle increases from top to bottom. An upper joint of the deformed hopper is larger than a discharge hole of the hyperbolical bunker, and a lower discharge hole of the deformed hopper is longer than the discharge hole of the hyperbolical bunker. The seal structure consists of seal material filled between the deformed hoper and the discharge hole of the hyperbolical bunker. The non-blockage deformed coal bunker has the advantages that coal blockage is avoided, blockage of the coal bunker less likely occurs even the coal is highly vicious and moist, the coal bunker needs no air cannon or loosener inside, and accordingly investment and operational cost is reduced.
Description
Affiliated technical field
The utility model equipment belongs to the storage facilities class, particularly is used for the not chute blockage abnormity coal bunker of coal-burning power plant.
Background technology
Coal breakage bucket chute blockage is to perplex one of power plant operation very important problem for a long time.Particularly when the surface moisture of overcast and rainy or coal was high, the chute blockage phenomenon was just more serious.The keypoint part of chute blockage is generally in the inlet and coal bunker bottom 0～3m scope of feeder.Behind the chute blockage, per tour work operations staff will beat coal bunker with sledgehammer, housing is dredged, and has so not only had a strong impact on the safe operation of CFBB, causes the certain economic loss, also can workman's personal safety be constituted a threat to.
The utility model content
The purpose of the utility model provides a kind of not chute blockage abnormity coal bunker that overcomes above-mentioned prior art weak point.
The technical scheme of utility model: chute blockage abnormity coal bunker not, form by last storehouse, reducing storehouse, hyperbola storehouse, hermetically-sealed construction, abnormity bucket respectively from top to bottom.Described upward storehouse is vertical cylinder or vertical rectangle structure.Storehouse in its connection suitable for reading of described reducing storehouse, end opening connects the hyperbola storehouse.Described hyperbola storehouse, the prone variation of its bulkhead is the track of exponential curve, and more past lower angle is big more.Described its upper interface of abnormity bucket is greater than the outlet in hyperbola storehouse, and the length of abnormity bucket lower part outlet is also greater than the outlet size in hyperbola storehouse.Described hermetically-sealed construction is filled with leakproofing material between abnormity bucket and the outlet of hyperbola storehouse.
Last storehouse is vertical cylinder or vertical rectangle structure, is difficult to take place chute blockage, owing to connect feeder under the coal bunker, the import of feeder can not be very big, so the process that coal bunker can have a cross section to dwindle on four sides from top to bottom.In prior art, the keypoint part of chute blockage is in the inlet and coal bunker bottom 0～3m scope of feeder.Coal can flow in the passage of this variable section could be down to feeder, and whether unobstructed coal is mobile in coal bunker, mainly contains two influence factors: the one, and the character of coal refers generally to the cohesiveness of coal, depends primarily on the moisture of coal and the content of ash content of coal medium clay soil; The 2nd, the contraction rule in coal bunker cross section.Because constantly shrink in the cross section of coal bunker, coal overcomes resistance and flows downward under the effect of deadweight, and one section height of every decline all needs particle is arranged again, and the constantly changing of the relative positions and extruding is to adapt to the variation of necking in.Under the certain condition of caking property of coal, select suitable coal bunker sectional shrinkage, can improve coal stream situation, thereby avoid or alleviate the chute blockage phenomenon.
Hyperbola storehouse end opening hopper slope changes, and begins from upper limb, and more past lower angle is big more; When coal cinder flowed in the cross section, though sectional area reduces, the coal grain compressed; But because hopper slope becomes big, the friction force between coal grain and headwall is diminished, it is big that vertical component becomes; Flow velocity is accelerated, and the coal grain presents uniform overall flow state in coal bunker.The variation of hyperbola headwall face is the track of exponential curve, makes its sectional shrinkage equivalence or approximately equivalent, thereby forms uniform uninterrupted flow.After adopting the hyperbola storehouse, the chute blockage phenomenon of coal bunker disappears basically.
The position that abnormity bucket is installed is the height of easy chute blockage of common coal bunker; Its structure upper interface is greater than the hyperbola coal bunker; Lower dimension is the little coal bunker of a dilatation also greater than the outlet size of hyperbola coal bunker, can reduce to discharge coal grain pressure for sidewall in flow process; Make and flow more smooth and easyly, avoid the chute blockage of this section.
Space between the salable abnormity bucket of hermetically-sealed construction and the outlet of hyperbola storehouse prevents that dust from leaking, and also the mediation during easy access is cleared up.
Therefore the utility model has the advantages that not chute blockage, even the fire coal of heavy body, high moisture content, coal bunker also is difficult for stopping up; Need not to adopt air bubble and loose machine in the coal bunker, reduce investment outlay and operating cost.
Description of drawings
Fig. 1 is the abnormity of chute blockage not coal bunker structural representation, and Fig. 2, Fig. 3 are respectively the front view and the birds-eye view of abnormity bucket.
Among the figure: the last storehouse of 1-, 2-reducing storehouse, 3-hyperbola storehouse, 4-hermetically-sealed construction, 5-abnormity bucket.
The specific embodiment
Further specify the content of utility model below in conjunction with accompanying drawing embodiment.
Chute blockage abnormity coal bunker not is made up of last storehouse 1, reducing storehouse 2, hyperbola storehouse 3, hermetically-sealed construction 4, abnormity bucket 5 respectively from top to bottom.Vertical cylinder shape or rectangular configuration are adopted in last storehouse 1, the liner macromolecule plate, and coal inlet is opened on top.Reducing storehouse 2 connects storehouse 1 end opening, and angle q is frustum cone structure or circumference structure, liner macromolecule plate greater than 62 degree.Reducing storehouse 2 end openings connect hyperbola storehouse 3, and hyperbola storehouse height 3.2m divides four sections, and every section 800mm, sectional shrinkage are definite value C=0.6, storehouse liner macromolecule plate.Abnormity bucket 5 inlet 200mm are stretched in 3 outlets of hyperbola storehouse, and adopt floor to be connected with abnormity bucket 5, and the hole of border adopts hermetically-sealed construction 4 sealings that canvas is done between them.Abnormity bucket 5 upper inlet are circular, and lower part outlet is a rectangle, and outlet can connect feeder inlet insertion plate door and feed zone.
About 150 cubic meters of this storehouse coal storage adapt to coal-fired water content 0～16%, coal-fired granularity 0～20mm.
