Abstract
The utility model relates to a chain row conveying type slag fishing machine for a coal-fired boiler, which uses a scraper slag fishing machine as the background technology and is composed of a tank body, the chain row, a drive device, etc. Steel plates through which the chain row is composed are successively overlapped and are assembled in a scale type; the chain row is supported through supporting wheels, receives the slag falling into the tank body in the tank body, and is driven through the drive device to convey the slag to a slag outlet of the slag fishing machine. Accordingly, the slag fishing resistance is fundamentally decreased, the service life of easy-damage parts is prolonged, and the utility model is reliable and practical.
Description
The utility model relates to a kind of new-type dragveyer in the coal-burning boiler slag removal equipment.
Dragveyer is one of capital equipment in the coal-burning boiler deashing device, its effect is that lime-ash that boiler is produced is in the workshop behind the water-cooled cooling, be discharged to sluiceway or other deashing device, present more employing be the scraper-type dragveyer, on the structure by last, lower groove, chain, scraper plate, regulating wheel, composition such as drive unit and directive wheel, lime-ash falls into cell body water quenching granulation during work, deposit to the upper groove body bottom, drive and two horizontal scraper plates that are connected together of chain by driving wheel, scrape dragveyer head oblique ascension gradually along the upper groove body base plate and go out the water surface, scrape the dragveyer slag notch at last, finish the slag work of dragging for, because the heavy poly-effect of lime-ash in water, scraper plate is when scraping lime-ash, must overcome the huge frictional resistance that heavy poly-lime-ash thing and dragveyer base plate produce earlier, dragveyer is in long-time running, chain certainly leads to distortion and abrasion, gradually can not be good fit with driving wheel, cause dragveyer to fall faults such as chain, if can not in time shut down after falling chain, the chain rupture fault will occur, cause very big difficulty for the unit conventional maintenance; Another kind of many usefulness be spiral dragveyer, its shortcoming is that the large volume clinker can not directly enter in the machine, the equipment abrasion is big, and certain limitation is arranged in the use.
The utility model is a background technology with the scraper-type dragveyer, provide a kind of safe and reliable, energy consumption is little, the new-type dragveyer of long service life--chain drives the conveying type dragveyer away.
The technical solution of the utility model is: drag for the top of the slag and be made of conveyer, drive unit and cell body etc., transmission device comprises chain row and chain row bracing or strutting arrangement, chain row is a kind of to be to be assembled by bar steel plate and chain that plane formula is arranged, simple in structure, but chain row is easily leaked ash downwards; Another kind of is flake type chain row, is made up of chain and the steel plate that laminates the flake type assembling successively, can solve the problem of downward leakage ash preferably, chain can be two, also can be made as many as required, assembles with steel plate, drive by drive unit, make whole chain row produce running.Chain row also can weld two row's steps by supports such as support wheel, directive wheel, driving wheel and regulating wheels on cell body two walls, add that above wear-resisting smooth liner plate replaces support wheel support chain row.Cell body can be divided into upper and lower cell body formula and single cell body formula, the former trough body structure and scraper-type dragveyer basically identical, chain row's impulse stroke is the same substantially with the scraper plate stroke of scraper-type dragveyer, support by bracing or strutting arrangement, the slag thing that to accept along upper groove body bottom is sent to dragveyer afterbody slag notch, finish drag for the slag task after, be turned back to lower groove, get back to upper groove body from afterbody again and accept the slag thing again, form continuous periodic duty.The structure of list cell body all immerses in the interior water of cell bodies the upper and lower layer of chain row, only lime-ash is pulled out at cell body head ascent stage premium on currency face, chain row's upper strata is that load layer is maked somebody a mere figurehead in cell body by the bracing or strutting arrangement support, accept the slag thing that falls into water in the cell body, whole chain row's impulse stroke mode is the same with upper and lower cell body formula chain row, all be to drive chain, make chain row circulation revolution, continuously the slag thing is sent to the slag notch of dragveyer head by drive unit.
The utility model has the advantages that: chain is arranged continuous conveying type and is replaced scraper plate to scrape dynamic formula, realized that effectively the slag thing is heavy poly-before the bottom land, when being in suspended state in water it is pulled out: chain drives load layer away and can adopt support wheel to support, fundamentally solved scraper-type dragveyer large drag forces because of heavy poly-lime-ash and the generation of base plate sliding friction when work, not only energy-conservation, and fundamentally prolonged service life of consumable accessory chain, constitute a kind of very reliability and durability New Slag, in addition, the chain conveyor dragveyer is because the particularity of its structure, its scope of application can expand work such as cleaning in the material processing or separation to, makes it have practical value widely.
Accompanying drawing 1 is a chain conveyor dragveyer schematic diagram
Accompanying drawing 2 is looked diagrammatic sectional view for the dragveyer master
Accompanying drawing 3 is a dragveyer side-looking diagrammatic sectional view
Reference numeral: 1. cell body 2. chains are arranged 3. chains, 4. flake type steel plates, 5. scraper plates, 6. support wheels, 7. regulating wheels, 8. directive wheels, 9. driving wheels, 10. cover plates, 11. lower floor's chains and are driven mud hole 13. lower dreg discharging holes 14. spout holes, 15. support wheel shafts on the support level 12. away
In conjunction with the accompanying drawings embodiment illustrate its structure and the course of work as follows:
Be full of water in the cell body 1 during work; water level keeps spout hole 14 to continue to flow; driving wheel 9 drives chain row 2 slow cycle operation in water of being made up of phosphorus chip steel plate 4 by chain 3; the lime-ash that produces in the boiler furnace falls into cell body water quenching granulation; simultaneously to deposit; accept by chain row 2; along with chain row 2 running is sent to the dragveyer outlet gradually; cover plate 10 is the movable mechanism of hinge with the cell wall junction; can prevent that the chain slit from leaking ash downwards; chain row 2 is by regulating wheel 7; directive wheel 8 is arranged central shoring with driving wheel 9 with endless chain and is become two-layer up and down; be load layer and backhaul layer; load layer is supported by support wheel 6; the backhaul layer is supported by the support level 11 on bottom land both sides; be covered with smooth antifriction material on the step; to reduce resistance; scraper plate 5 main effects are when operating in the backhaul layer; the a small amount of what ash that drains to bottom land is scraped to afterbody; then forward on the load layer and discharge; but guarantee the operation of dragveyer long-term safety; the effect of spout hole 14 is heights of water level in the protection cell body 1; last mud hole 12 is to discharge buck in the cell body when dragveyer is shut down maintenance with the effect in lower dreg discharging hole 13; support wheel 6 and 15 assemblings of support wheel shaft; the rigidity intensity of chain row steel plate when this three support wheel assemblings arranged side by side can be strengthened running to the support wheel top; be enough to bear the big coke block that falls into cell body; simultaneously when coke button is fallen between the two support wheel shafts; because chain row's mass action; it there is certain cushioning effect; therefore the dragveyer of this structure not only reduces the dragveyer resistance; and the impact can accept big coke block and fall into cell body the time, have stronger practicality.
