Description
Technical field
This practicality newly belongs to kind of a bulk material technical field of conveying machinery, particularly a kind of scraper chain structure and semi-door type scratch board reclaimer thereof.
Background technology
Bulk material generally refers to that to be deposited in together a large amount of without packing materials, monomer in block, granular, spherical, powdery etc., such as ore, coke, limestone, coal dust etc.For large-scale steel plant and thermal powerplant, large bulk cargo is had every day to carry out windrow, material stock, material extracting operation.The access of bulk materials has outdoor stock ground usually, and stock ground is closed in bar shaped, several mode in ring seal stock ground.In these modes, outdoor stock ground floor area is large, and material is directly subject to the impact of weather conditions, and environmental pollution is large, is progressively being closed stock ground replacement; Ring seal stock ground generally can only be used for accessing single material, so be widely used in accessing bunker coal at thermal powerplant; Bar shaped closes stock ground by adding partition wall, may be used for accessing diversified bulk cargo, has catered to the feature of steel plant's diversification of feedstock, in recent years progressively increases in steel plant's application so stock ground is closed in bar shaped.
Semi-door type scratch board reclaimer is applied in the closed bar shaped stock yard of loose unpacked material engineering, is limestone, ore, coal dust, the take out device of the raw materials such as coke.Semi-door type scratch board reclaimer primarily of downside running wheel and guiding, fixation side end carriage, door shape tie-beam, steel wire rope hoisting mechanism; Scraper chain arm for taking material, float side beam, the compositions such as upside running wheel and guiding.
After semi-door type scratch board reclaimer receives the feeding instruction of raw material control center, carry out material extracting operation, main process is as follows: whole semi-door type scratch board reclaimer is under wheel drives, the position of scraping material can be moved longitudinally to along material strip, scraper chain starts and starts cycle operation, then, hoisting mechanism drive arm for taking material transfer to the certain degree of depth of charge level wedging and remain unchanged, by the scraper plate on chain by raw material scrapings such as ores on belt feeder; Whole semi-door type scratch board reclaimer is with the longitudinal direction traversing scraping that complete a bed of material of charge level of certain speed along material strip simultaneously; After completing the doses needing scraping, arm for taking material lifts, and scraper chain is out of service.
For semi-door type scratch board reclaimer, scraper chain is main stressed member and daily service service object.Wherein chain is to the support and connection mode of scraper plate, have impact on the bulk strength of scraper chain to a great extent, determines tolerance and the number of stoppages of scraper chain.In the scraper chain of existing various scraper reclaimer configuration in the market, the one-sided and bolted structure of scraper plate of a lot of inner plate adopted, its intensity is not high.In addition, scraper chain is due to long-term scraping material, its operating mode very severe, rational chain structure and lubricating method need be taked, in the service life that guarantee is longer, more existing scraper chain adopts and arranges grease oil nipple in bearing pin one end in the market, adopts weekly lubricating chain of manually buying oil, its work capacity is huge, brings inconvenience.
