Embodiment 1
As Figure 1-3, a kind of sealing coal yard, comprises sealing rack, feeding mechanism, blanking mechanism and material fetching mechanism.
Described sealing rack 6 for cross-sectional plane be semi-round long strip type arch hermetically-sealed construction.This enclosed construction has solved coal yard problem of environmental pollution to external world.Cross-sectional plane is semicircular structure, and dump, taking center line as symmetric line, is arranged symmetrically in both sides, and from the formation shape of the utility model dump, the dump degree of utilization forming in the space of semicircular arc is the highest, and reserves are large.Long strip type arch configuration can arbitrarily extend in the longitudinal direction, so that the enlarging of factory building adapts to place enlarging requirement.The plant project that is particularly suitable for large-scale storage Blending Base project and extends continuously.In addition, sealing rack can also be other structures, as polygonized structure etc.
Described feeding mechanism comprises charging belt conveyer 1, blanking mechanism comprises stocker 2, cantilever belt conveyor 3 and column 7, material fetching mechanism comprises feeding belt conveyer 4 and scraper reclaimer 5, described column 7 is located at sealing rack 6 lateral middle, the both sides of column 7 are dump, the top of column 7 is loading bay belt conveyer 1 and windrow walking track 9, and the middle part of column 7 is feeding walking track 8; The stocker 2 vertically moving along dump is established in described charging belt conveyer 1 top, the windrow walking track 9 of stocker 2 is arranged in the both sides of charging belt conveyer 1, stocker 2 can be walked on this charging belt conveyer 1, and charging belt conveyer 1 is delivered to coal on the cantilever belt conveyor 3 of stocker 2; The walking track in described scraper reclaimer 5 door frame outsides is located at ground, the walking track of door frame inner side is located at the top of column 7, scraper reclaimer door frame is high-order to be arranged, scraper plate radius reduces, dump returns the rate of getting and is about 95%, suitable with closed circle coal yard, than the rate of getting high approximately 20% of returning of bucket wheel machine coal yard 75%.Scraper reclaimer 5 is suspended on the steelframe 12 of feeding walking track 8 tops, its both sides, and by the elevation-depression angle of hoist cable mechanism 13 and dump shape adjustment scraper reclaimer 5, and scraper reclaimer 5 vertically moves along dump by the feeding track 8 of walking; The sensor that scraper reclaimer contacts with dump is housed in hoist cable mechanism 13, can controls the degree of depth that contacts of scraper reclaimer and dump; Realize the coal of getting to whole dump by the scraper reclaimer structure with dump change pitch, hoist cable mechanism 13 can regulate rope length and control the luffing angle of scraper reclaimer.Feeding belt conveyer 4 is located at ground, and its initiating terminal is corresponding with the tail end of scraper reclaimer 5.Described scraper reclaimer 5 is L shaped structure, its underpart is provided with scraper turning point 11, the head end of scraper reclaimer 5 is hanging type bascule, and the head end of scraper reclaimer does arc crank motion in dump taking scraper turning point 11 as turning cylinder, the up perk of the tail end of this scraper reclaimer 5, is above the ground level.
Described coal-stopping wall 10 is located between column 7, is positioned at the middle part of two dumps.In the time that two dumps are identical coal, also can cancel coal-stopping wall, only retain corresponding column.Described coal-stopping wall 10 tops longitudinally arrange one or two charging belt conveyers 1 along sealing rack 6, on charging belt conveyer 1, arrange one or several portable stockers 2, cantilever belt conveyor 3 way traffics on stocker 2, to two dump coal piling in coal yard.Coal yard both sides scraper reclaimer 5 exports on ground and arranges and two-way or four tunnel feeding belt conveyers 4 configure a scraper reclaimer 5 on every road feeding belt conveyer 4; Exert oneself when larger when feeding belt conveyer, also can configure many scraper-type reclaimers 5.
Specifically in the present embodiment, described coal yard is closed full automatic bar shaped coal yard, 2 dumps of 1 coal yard, and adjacent dump shares coal-stopping wall.Same sealing coal yard is arranged symmetrically with two dumps, middle public coal-stopping wall, according to coal yard reserves and site condition, in the time that coal yard is 80-145m containing sealing rack width, dump height can be 15-30m, than the dump profile sectional area about 40% of the bucket wheel machine coal yard of approximate dump shape.
In addition, described stocker also can adopt moving unloading vehicle to substitute.If employing moving unloading vehicle, dump width and coal yard sectional area will greatly reduce, and coal yard reserves and utilization of area rate also will decrease.
The control system of sealing coal yard described in the utility model also comprises the temperature monitoring system 14, smoke monitoring system 15 and the laser coal checking system 16 that are connected with coal yard master controller.
Described temperature monitoring system 14 is located on column 7 and coal-stopping wall 10, and in the time temperature alarming having been detected, scraper reclaimer 5, by the coal storage in preferential scraping high-temperature region, occurs to reduce spontaneous combustion.
Smoke monitoring system 15 is located on sealing rack 6, for matching with temperature monitoring system, and the smog in monitoring coal yard.
Laser coal checking system 16 is located on sealing rack 6 or cantilever belt conveyor 3.
In the time that laser coal checking system is located at the sealing rack 6 of described coal yard, laser coal checking system can, to dump shape real time scan, be monitored dump shape and the time of storing up in real time, to dump reserves, store up the time, store up the data real-time update such as ature of coal.
In the time that laser coal checking system is located on cantilever belt conveyor 3, in the time of cantilever belt conveyor 3 and stocker 2 orbiting, can measure dump, related data can be upgraded according to scanning times, and this scheme can reduce construction investment.
Under the cooperation of above-mentioned Monitoring System of Tram, this coal yard system can be accomplished unattended fully automatic operation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
