Description
[technical field]
The utility model relates to boiler Aided Machine technical field, specifically a kind of Wave-shaped line separation energy-saving coal feeding machine.
[background technology]
Chain-grate boiler is since the foundation initial stage introduces, and because of its mechanization degree height, stable performance, reliable operation develop rapidly in China.At present, domestic chain-grate boiler has reached more than 800,000, and annual also with 9% speed increment, and its supporting boiler is from 1～10t/h medium small boiler, the small hydropower station boiler more than 35t/h, and range of application is very extensive.The annual raw coal that consumes reaches more than 900,000,000 tons, accounts for more than 1/3 of national raw coal output, and Fuel Consumption is quite big.The conventional chains boiler exists problems: at first, the coal-feeding mode of chain-grate boiler is that the raw coal in the coal bunker relies on self gravitation directly to fall on the fire grate, scrapes pressure through the coal flashboard again, forms very closely knit coal bed texture, and therefore, gas permeability is poor, ventilation is difficult.Secondly, the fuel composition that the coal seam of chain-grate boiler is not of uniform size, the thickness particle mixes, the compaction rate in coal seam is also different; loose because of the coal seam easily in the place that bulky grain is concentrated; ventilation is big, easily forms " burner " or " air port " and causes fire grate air distribution inequality, and burning is uneven.In few place that ventilates, coal combustion is insufficient, and boiler slag carbon content is higher, and heat loss due to combustibles in refuse is big.These problems become boiler industry problem to be solved.Though the existing and matching used energy-conservation coal feeder of chain-grate boiler on the market, ventilation and combustion position are improved, but also exist many weak points: from the fire grate coal seam outwardly, still exist many coal cinders not have completing combustion, the coal seam needs better gas permeability.Secondly, this coal feeder occurs being stuck between cylinder and the upper lock gate because of big coal cinder through regular meeting, and cylinder can not rotate, and makes to give the boiler coal supply, thereby has a strong impact on the operate as normal of boiler.
[summary of the invention]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of Wave-shaped line separation energy-saving coal feeding machine is provided.Can blend freezing coal, loose, the raw coal of thickness inequality is separated on fire grate greatly automatically, in, little loose coal seam, and the upper surface waviness in coal seam, more can improve the gas permeability of coal seam energy, in combustion process, flare is evenly neat, sufficient combustion, avoided " burner " or " air port " phenomenon, a nearly step of boiler slag carbon content reduces, and heat loss due to combustibles in refuse reduces, the thermal efficiency improves, soft coal amount because coarse coal below the coal seam, bleeds in the fire grate also significantly reduces, and has improved flammability and fuel performance, conformability to coal also improves greatly, has played better energy saving purposes.When occurring being stuck between cylinder and the upper lock gate because of big coal cinder, when cylinder can not rotate, movable guide plate of the present utility model can be shifted onto that side of header board, open urgent feeding plate, space between urgent feeding plate and the movable guide plate just forms a urgent blanking storehouse, coal can go down from urgent blanking storehouse, gives the boiler coal supply, thereby has improved boiler operation reliability, security.
For achieving the above object, the utility model proposes a kind of Wave-shaped line separation energy-saving coal feeding machine, comprise front and rear panel, the cam-type doffer, hold up plate, coal scraper plate, cylinder, sifter, the waveform tail gates, upper lock gate, fixed head, urgent feeding plate, movable guide plate, left side plate, back plate 9, header board 1 fixedly connected side plate 16, the front end face of back plate 9 connects sifter 6, the middle part of header board 1 rear end face connects an end of holding up plate 3, hold up the other end of plate 3 to connect coal scraper plate 4, coal scraper plate 4 connects cylinder 5, it is characterized in that cylinder 5 tops are provided with fixed head 13, the fixedly connected side plate 16 of end about fixed head 13, fixed head 13 upper end connection activity guide plates 15, back plate 9 upper ends connect urgent feeding plate 14, and back plate 9 lower ends connect waveform tail gates 7, and waveform tail gates 7 lower ends are provided with waveform tooth bar 8; Hold up on the side plate 16 of plate 3 back upper places cam-type doffer 2 is housed; Fixed head 13 rear sides are provided with upper lock gate 12, and upper lock gate 12 rear end faces adopt tooth bar to connect gear 10, and gear 10 connects roller bearing 11, and roller bearing 11 two ends connect side plate 16.
The utility model is compared with prior art, and novel structure is simple to operate, reliable, easy for installation, coal cinder more can fully burn, and energy-saving effect is also more obvious, designed movable guide plate, make the coal load quantity of coal bunker also improve greatly, cylinder breaks down in the time of can not rotating, and can give the boiler coal supply by urgent blanking storehouse, thereby improved boiler operation reliability, security, be worthy of popularization.
