Abstract
The utility model provides a stone coal equal pressure discharging, sealing, and collecting device. The utility model adopts the following technical scheme that the device comprises a charge pipe, wherein the discharging end of the charge pipe is connected with the inlet of a sealed storehouse through a switching mechanism in a sealing manner, and the outlet of the sealed storehouse is connected with a stone coal collecting box in a sealing manner. The utility model has simple structure and low processing and manufacturing cost; and in the technical scheme, the stone coal discharge outlet and the stone coal collecting box are always in strict equal pressure state, when the operation of the stone coal collecting box is changed, the switching mechanism at the discharging end of the charge pipe can keep a coal pulverizer no leakage of hot air pressure, the whole stone coal collection process is a continuous uninterrupted process, therefore, no stone coal accumulation is caused in the stone coal storehouse of the coal pulverizer, the abrasion of such mechanical components as scrapers, mating skirts and the like is reduced, and the running period is prolonged effectively.
Description
Technical field
The utility model relates to a kind of stone coal collecting device, relates in particular to a kind of pebble coal equal pressure discharging sealing gathering-device.
Background technology
In thermal power generation corporations, medium-speed pulverizer is widely used in more than 350,000 kilowatts in the generating set, and medium-speed pulverizer is extensive not as steel ball cartridge type coal pulverizer to coal adaptability, but in coal scope that it is suitable for, it is few to have a metal consumption, reduced investment, the coal-grinding power consumption is little, and the metal abrasion are hanged down and advantages such as noise is little.Medium-speed pulverizer is applicable to and grinds bituminous coal and meager coal.Generally require pit ash to be not more than 30-40, Ha Shi grindability coefficient HGI should be greater than 50, and former moisture content of coal is no more than 12.For E type mill and MPS type mill, under suitably high hot blast temperature, can grind the raw coal that moisture is 20-25.
The stone coal that medium-speed pulverizer when operation produces is meant the low combustion value gangue that institute is contained self in the raw coal, because the hardness of gangue is much larger than the worth electric coal of high combustion.When medium-speed pulverizer moves, be not rolled into powder and proportion powder greater than designing requirement, spare and will discharge coal pulverizer through the scraper plate brush by coal pulverizer base floss hole, so just produced medium-speed pulverizer stone coal draining technology equipment.The smooth and easy continuous degree of stone coal discharging directly has influence on the running status of coal pulverizer, even can directly influence the running status of generating set; So the stone coal emission problem of medium-speed pulverizer has become boiler of power plant specialty regular maintenance major tasks content, accounts for more than 45% of everyday devices maintenance.
Existing stone coal processing mode has:
1, artificial mode: the stone coal is sent to the elsewhere to the stone coal with dolly or tractor by manual type after discharging from medium-speed pulverizer fully.
2, stone coal Hydraulic Transportation System: mainly utilize high-pressure washing water the stone coal to be transported to dragveyer, be discharged into truck again and transport by pipeline; Or utilize high-pressure washing water that the stone coal is transported to slag bath, and be transported to drainage bin with pulp pump again, pull away after the dehydration.
3, adopt jigging conveyer to carry: with jigging conveyer is main conveying equipment, also adopts rubber conveyer simultaneously.The stone coal enters the stone coal bunker by medium-speed pulverizer, enters the jigging conveyer of its underpart after material is full, to expecting rubber conveyer and being transported in the feed bin, regularly is discharged into and is transported to the stockyard in the truck then.
The shortcoming of existing various processing modes:
1, the shortcoming of artificial mode: (1) because the stone coal contains dust and coal dust, and dust fills the air in the coal pulverizer discharge process, environment is abominable; (2) the stone coal that transports in the process of dolly or tractor is scattered,, influence the plant environment health; (3) labor strength is big; (4) because by artificial local operation, central station of floating dock can't be known the emissions status of stone coal.
2, the shortcoming of stone coal Hydraulic Transportation System: (1) system equipment is many, and complexity is set; (2) floor space is big; (3) need great lot of water resources, operation and maintenance cost height; (4), stop up outlet when washing again behind the certain interval of time easily because the sub-coal bunker of every socle is flushing at interval; (5) cause easily to turn one's coat and flood the coal pulverizer accident; (6) thus dust and particle in stock tank easily deposition cause the slurry pump body to stop up.
3, the shortcoming that adopts jigging conveyer to carry: (1) shaking(-pan) conveyer is poorly sealed, causes dust from flying easily; (2) the easy airborne dust and the stone coal that is scattered in the adhesive tape course of conveying; (3) high temperature stone coal spontaneous combustion easily in course of conveying causes adhesive tape to damage, and has potential fire hazard; (4) it is limited that belt is carried hoisting depth; (5) need install ventilating and purifying air system additional in adhesive tape transhipment part.
Because existing stone coal processing machine exists above-mentioned shortcoming, so, exist in addition improved necessity.
