The coal regulating device is arranged on a top of a machine body, the coal transferring roller is arranged under the coal regulating device, and a lower crushing roller is arranged at one side of the coal transferring roller. The coal transferring roller, the lower crushing roller and a main shaft sprocket of a grate are connected with the same chain, an upper crushing roller is arranged above the lower crushing roller, and the coal transferring roller is engaged with a reverse wheel via a gear. The reverse wheel is connected with the upper crushing roller via a chain, the sifter is in inclined arrangement under the crushing roller, the sieve penetrating device is arranged under the sifter, and the jetting pipe is arranged on one side of the sifter. The utility model can increase 8-15% heat efficiency of the boiler, reduce 10-15% carbon content of coal slag, increase 100-150 DEG of boiler chamber temperature and save more than 10% coal.
Description
The utility model belongs to a kind of coal feeder that is used for boiler.
Traditional coal feeder is the natural gravity that utilizes coal, is slipped naturally to grate surface by coal bunker or last coal bunker, and shortcoming is that coal bed texture is unreasonable, and combustion efficiency is poor, the phosphorus content height, and boiler efficiency is low, and side seal, retaining quarrel device, coal flashboard are easily by the flame scaling loss; And existing layer-stepping feeder lacks broken function, and bulk or coal drystone etc. is blocked easily, makes that the furrow phenomenon appears in the coal seam on the fire grate, and coal bed texture is unreasonable; Lack and do the humidity that wet jet pipe can not be regulated coal, combustion efficiency is not ideal enough.
Goal of the invention of the present utility model is to provide a kind of coal feeder that coal bed texture is reasonable, can regulate the humidity of coal that makes.
The utility model is achieved by the following scheme: feeder is by transferring device for coal, coal-transporting roller, breaker roll, sifter, saturating cribellum and discharge jet are formed, it is characterized in that transferring device for coal to be arranged at the body top, transfer device for coal to transfer the adjustment axle of coal plate to form by the accent coal plate and the control of vertical setting, below transferring device for coal, coal-transporting roller is set, coal-transporting roller one side is provided with down breaker roll, coal-transporting roller is connected by a chain together with following breaker roll and fire grate spindle sprocket, following breaker roll upside is provided with breaker roll, coal-transporting roller is meshed with gear with reverse wheel, reverse wheel links to each other with chain with last breaker roll, be obliquely installed sifter below the breaker roll down, sifter is made up of several layers of screen cloth, the net of screen cloth is apart from being attenuated successively by upper strata to lower floor, and the sifter below is provided with cribellum, and a side of sifter is established jet pipe.
The utlity model has following advantage:
1, because feeder makes the rational in infrastructure of coal seam, improved draught capacity, the combustion efficiency in coal seam is greatly improved, fire box temperature improves significantly, and the phosphorus content in the coal quarrel also reduces significantly, and boiler is enlarged to some extent to the adaptability of coal.
2, because feeder has broken function, make bigger coal cinder, coal drystone or freeze coal cinder to be fractured into rational coal cinder, more help burning.
3, thereby ejector reasonably sprays the burning capacity that certain moisture has improved the coal seam to dry coal.
4, use this feeder to reduce the fault rate of boiler, the service life of having improved boiler greatly.Thereby the phenomenon of having avoided the fire grate front portion to leak coal; Avoid the fire grate afterbody to run flourishing phenomenon, effectively protected retaining quarrel device; When fire grate stopped operating, this machine stopped coal supply automatically, did not therefore just have scaling loss coal bunker or coal flashboard phenomenon; Because coal bed texture is reasonable, burning is even, and fire grate side seal burning phenomenon also must be to thorough root smelting.
5, feeder is to utilize the surplus moving of fire grate main shaft to carry out work, does not need any power source that adds, thereby has saved electric energy.
The utility model can improve the thermal efficiency 8-15% of boiler, and the phosphorus content of coal quarrel can reduce 10-15%, and fire box temperature can improve 100-150 ℃, economizes on coal more than 10%.
Accompanying drawing 1 is the structural representation of feeder.
Be described further below in conjunction with 1 pair of the utility model of accompanying drawing:
As shown in Figure 1, feeder is by transferring device for coal, coal-transporting roller 2, on, following breaker roll 11,3, sifter 9, saturating cribellum 8 and discharge jet 4 are formed, transfer device for coal to be arranged at the body top, transfer device for coal to transfer the adjustment axle 14 of coal plate to form by the accent coal plate 15 and the control of vertical setting, adjust the angle of inclination that axle 14 can change accent coal plate 15 by regulating, with control slide coal direction and coal output, below transferring device for coal, coal-transporting roller 2 is set, coal-transporting roller 2 one sides are provided with down breaker roll 3, coal-transporting roller 2, following breaker roll 3 and fire grate spindle sprocket 7 are connected by a chain 5, following breaker roll 3 upsides are provided with breaker roll 11, the axis of last breaker roll 11 can slide along last breaker roll track 13, its track reverse wheel 1 center of circle be the center with reverse wheel 1 and on broken wheel 11 centers of circle be on the formed one section camber line of radius, on regulating, following breaker roll 11,3 spacing and control coal output, coal-transporting roller 2 and reverse wheel 1 are with gears engaged, reverse wheel 1 and last breaker roll 11 link to each other with chain, be obliquely installed sifter 9 below the breaker roll 3 down, sifter 9 is made up of several layers of screen cloth, the net of screen cloth is apart from being attenuated successively by upper strata to lower floor, sifter 9 belows are provided with cribellum 8, following breaker roll 3 drives saturating cribellum 8 by connecting rod 10, make the top of cribellum 8 reciprocating along the screen cloth slit, a side of sifter 9 is provided with jet pipe 4.
During feeder work, clockwise rotate by fire grate main shaft drives coal-transporting roller 2 and following breaker roll 3, reverse wheel 1 rotates counterclockwise with 11 of last breaker rolls, at first, coal drops between coal-transporting roller 2 and the following breaker roll 3 by transferring coal plate 15, general coal then passes through breaker roll 3 up and down smoothly, 11 centre, bigger lump coal, coal drystone freezes coal cinder then by breaker roll 3 up and down, 11 are broken into rational coal cinder, by the adjusting rod 12 of regulating breaker roll 11, on regulating, following breaker roll 11,12 spacing, thereby the size of control coal cinder, the coal water spray of jet pipe 4 on sifter 9, so that make coal by suitably moistening, when coal cinder drops on sifter 9 upper stratas, coarse coal slides on the moving from left to right grate surface 6 along sifter 9 upper strata screen clothes, a little bit smaller coal cinder then drops on time one deck screen cloth face and along it and slides to grate surface 6, because the motion of grate surface 6, a little bit smaller coal cinder then drops on the gathering coal, for sifter 9 with multilayer screen cloth, its screening process can the rest may be inferred, obtains bulk at last following on grate surface 6, fritter is in the coal seam of the moistening appropriateness of last even structure.Because following breaker roll 3 drives cribellum 8 by connecting rod, makes the Xiang Duanshun screen cloth slit of cribellum 8 reciprocating, to avoid the obstruction of sifter 9.
