Abstract
The utility model discloses a circulating fluidized bed boiler coaling system for a thermal power station, which is characterized in that a cylinder vibrating screen is obliquely arranged, the upper end of the cylinder vibrating screen is connected with a coal receiving port through a coal receiving port conveyor belt, the lower end of the cylinder vibrating screen is connected to the inlet of a crusher through a coal briquette sliding chute, and the outlet of the crusher is connected to the coal receiving port of a sending back conveyor belt; a fine coal outlet is arranged below the cylinder vibrating screen, and fine coal separated out by the cylinder vibrating screen falls at a fine coal outlet; the fine coal outlet is connected to a coal bin through a coal bin conveyor belt. The circulating fluidized bed boiler coaling system provided by the utility model only enables the fine coal passing through the cylinder vibrating screen to enter the coal bin, ensures the coal feeding granularity required by the circulating fluidized bed boiler coaling, and can prevent sundries such as large coal stone, branches and the like from entering the coal bin.
Description
Technical field
The utility model relates to a kind of thermo-power station CFBB coaling system.
Background technology
As shown in Figure 2, current steam power plant CFBB coaling system used, the general disintegrating machine that adopts is front with vibratory sieve, duff is directly sent into coal bunker from coal bunker conveyer belt by the sieve aperture of vibratory sieve 10, fail after crusher in crushing, from bottom, to discharge and directly by belt conveyor, send into coal bunker by the bulk coal stone of sieve aperture, but pulverize and can not guarantee that bulk coal stone pulverized as suitable particle size through pulverizer, and part branch and bulk also enter coal bunker compared with hard coal stone (cannot be broken) thereupon, thereby the granularity that causes coal can not meet the demands and occur the phenomenon that coal supply stops up and lime-ash can not put, in addition, this device is when overcast and rainy coal is wet, and vibratory sieve sieve aperture major part is blocked, thereby causes disintegrating machine to stop up, and finally causes whole coaling system paralysis boiler to be forced to the generation of blowing out phenomenon, affects the safe operation of boiler plant.
Utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, and a kind of thermo-power station CFBB coaling system is provided, to guaranteeing that Coal Feeding in Circulating Fluidized Bed Furnace reaches requirement granularity and solves blockage problem.
The utility model is that technical solution problem adopts following technical scheme:
The utility model thermo-power station CFBB coaling system, its design feature is: be tiltedly installed with cylinder vibratory sieve, the upper end of described cylinder vibratory sieve is stood coal mouth conveyer belt and is connected with being subject to coal mouth, the lower end of described cylinder vibratory sieve is connected in the entrance of disintegrating machine through coal cinder chute, the outlet of described disintegrating machine is returned conveyer belt and is connected in and is subject to coal mouth through sending; The below of described cylinder vibratory sieve arranges duff outlet, and the duff blanking separating through described cylinder Vibration Screen exports in described duff; Described duff outlet is connected in coal bunker through coal bunker conveyer belt.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model makes to only have the duff by cylinder vibratory sieve sieve aperture can enter coal bunker, has guaranteed that Coal Feeding in Circulating Fluidized Bed Furnace reaches requirement granularity, has avoided the foreign material such as bulk coal stone and branch to enter coal bunker;
2, the utility model recycles the bulk coal stone by cylinder vibratory sieve sieve aperture not and enters cylinder vibratory sieve and sieve after pulverizer is pulverized repeatedly, and high to the utilization rate of coal stone, method is simple;
3, the utility model lists and indexes out by foreign material such as branches, has avoided the obstruction to cylinder vibratory sieve and disintegrating machine.
Accompanying drawing explanation
Fig. 1 is the structural representation of CFBB coaling gear for the utility model thermo-power station;
Fig. 2 is the structural representation of CFBB coaling gear for the thermo-power station of prior art;
Number in the figure: 1 is subject to coal mouth; 2 are subject to coal mouth conveyer belt; 3 cylinder vibratory sieves; 4 coal cinder chutes; 5 disintegrating machines; 6 send and return conveyer belt; 7 duff outlets; 8 coal bunker conveyer belts; 9 coal bunkers; 10 vibratory sieves.
The specific embodiment
As shown in Figure 1, the present embodiment thermo-power station by the structure of CFBB coaling system is: be tiltedly installed with cylinder vibratory sieve 3, the upper end of cylinder vibratory sieve 3 is stood coal mouth conveyer belt 2 and is connected with being subject to coal mouth 1, the lower end of cylinder vibratory sieve 3 is connected in the entrance of disintegrating machine 5 through coal cinder chute 4, the outlet of described disintegrating machine 5 is returned conveyer belt 6 and is connected in and is subject to coal mouth 1 through sending; The below of described cylinder vibratory sieve 3 arranges duff outlet 7, and the duff blanking sieving out through described cylinder vibratory sieve 3 is in described duff outlet 7; Described duff outlet 7 is connected in coal bunker 9 through coal bunker conveyer belt 8.
In concrete enforcement, raw coal arrives cylinder vibratory sieve 3 from being subject to coal mouth 1 to stand coal mouth conveyer belt 2, and after 3 screenings of cylinder vibratory sieve, duff blanking, to duff outlet 7, then arrives coal bunker 9 by coal bunker conveyer belt 8; The foreign material such as bulk coal stone and branch are failed by the sieve aperture of cylinder vibratory sieve 3, and enter disintegrating machine 5 by coal cinder chute 4, through disintegrating machine 5 fragmentations, by sending, return conveyer belt 6 and again arrive and be subject to coal mouth 1, reciprocation cycle, bulk coal stone is circulated broken until meet the requirements, the flexible cord branch that simultaneously coal can be sneaked into together etc. lists and indexes out, make to only have the duff by cylinder vibratory sieve sieve aperture can enter coal bunker, guaranteed that Coal Feeding in Circulating Fluidized Bed Furnace reaches requirement granularity, avoided the foreign material such as bulk coal stone and branch to enter coal bunker.
