Abstract
The utility model relates to a coal feeder for a boiler, which mainly comprises a rotating shaft (1), a roller (2), vanes (3), a driven chain pulley (4), a chain (5) and a drive chain pulley (6), wherein the roller (2) and the rotating shaft (1) are coaxial, and the roller (2) is fixed on the rotating shaft (1). Four to ten vanes (3) are evenly fixed on the roller (2), one end of the rotating shaft (1) is provided with the driven chain pulley (4), and the rotating shaft (1) is arranged on the upper part of a chain grate (7) of a boiler and on a coal discharge port of a coal hopper (8). The drive chain pulley (6) is arranged on a transmission shaft (9) of the chain grate of the boiler, and burning briquettes are turned over to the lower side when the vanes (3) rotate. Therefore, the burning mode from bottom to top is realized, the briquettes can be completely burned and the utility model provides a new way for burning the briquettes.
Description
The utility model belongs to dispenser, relates in particular to a kind of coal feeder of industrial chain furnace grate.
The diffusing coal efficient of burning in boiler is low, seriously polluted, burns moulded coal and can economize on coal 25%, can also reduce flue dust and SO
2Discharge capacity, improve the thermal efficiency, the protection environment is had very important significance.But present existing Industrial Boiler is not suitable for burning moulded coal, most of Industrial Boilers, all adopt traveling-grate stoker, fuel is brought burner hearth from coal feed point into by the fire grate of motion, relies on the heat radiation of burner hearth to be begun progressively to burn by the top layer downwards, and this mode of burning from top to bottom is not suitable for moulded coal, moulded coal is incomplete combustion in this boiler, fire is not prosperous yet, and stops burning easily, has seriously restricted the popularization of moulded coal.
The purpose of this utility model provides a kind of industrial chain furnace grate that makes and realizes the coal feeder of combustion system from the bottom up.
The purpose of this utility model is achieved in that it comprises turning cylinder, cylinder, blade, drive sprocket, chain, by movable sprocket, cylinder is coaxial and be fixed on the turning cylinder with turning cylinder, evenly be fixed with 4-10 blade on the cylinder, one end of turning cylinder has one by movable sprocket, drive sprocket is connected with passive chain gear transmission by chain, during use turning cylinder is installed in the chain fire-gate top of boiler, coal mouth place under the coal bunker, drive sprocket is installed on the chain fire-gate power transmission shaft, chain fire-gate power transmission shaft rotates, drive sprocket rotates, make passive sprocket rotation by chain, thereby make the cylinder on turning cylinder and the turning cylinder, blade rotation, between two blades near the coal of burner hearth, because the burning and the heat radiation of burner hearth fire are lighted it, it is the moulded coal that has caught fire that cylinder rotates the fuel bottom that the coal make between two blades near the burner hearth burning promptly drops on the traveling-grate stoker below rolling, be the moulded coal that does not catch fire above, formed combustion system from the bottom up, solved the problem of starting to exchange fire that chain grate boiler burns moulded coal, make fire burn more prosperous and more prosperous, moulded coal can completing combustion.
The utlity model has following advantage:
1. thoroughly change the mode that the conventional chains furnace grate burns from top to bottom, made fuel combustion complete, improved the thermal efficiency, saved the energy, reduced the discharge capacity of the flue dust and the SO2 of Industrial Boiler, reduced the environmental pollution of atmosphere.
2. because the utility model makes Industrial Boiler can burn moulded coal, so help the utilization and extention of moulded coal.
3. of the present utility model simple in structure, do not need to increase in addition power.
Below in conjunction with accompanying drawing the utility model is further described in detail.
Fig. 1 is a scheme of installation of the present utility model.
Fig. 2 is a transmission schematic diagram of the present utility model.
As shown in the figure, 1 is turning cylinder, and 2 is cylinder, and 3 is blade, and 4 is by movable sprocket, and 5 is chain, 6 is drive sprocket, and 7 is traveling-grate stoker, and 8 is coal bunker, and 9 is power transmission shaft, and 10 is shaft coupling, 11 is decelerator, and 12 is motor, and 13 is belt pulley, and 14 is belt, and 15 is boiler body.
Top at traveling- grate stoker 7,8 times coal mouths of coal bunker place is equipped with turning cylinder 1, on turning cylinder 1, be fixed with the cylinder 2 coaxial with turning cylinder 1, evenly be fixed with 4-10 blade 3 on the cylinder 2, be equipped with one on the turning cylinder 1 by movable sprocket 4, on the power transmission shaft 9 of traveling-grate stoker 7, drive sprocket 6 is housed, drive sprocket 6 with they are linked up by chain 5 by movable sprocket 4, the power transmission shaft 9 of traveling-grate stoker 7 rotates, can drive by movable sprocket 4 by drive sprocket 6 and chain 5 and to rotate, thereby turning cylinder 1 and cylinder 2 are rotated, constantly give traveling-grate stoker 7 coals, the coal of close burner hearth between the blade 3 is because the burning and the heat radiation of burner hearth fire are lighted it; Cylinder 2 rotates below the coal that makes between the blade 3 near burner hearth rolls to, dropping on promptly that the fuel bottom is the moulded coal that has caught fire on the reciprocal grate 7, is the moulded coal that does not catch fire above, has formed the mode of burning from the bottom up, make moulded coal burn more prosperous and more prosperous, reach completing combustion.
Turning cylinder 1 and cylinder 2 and blade 3 can be cast as one.
Claims (3)
1. boiler coal feeding device, mainly comprise turning cylinder (1), cylinder (2), blade (3), by movable sprocket (4), chain (5), drive sprocket (6), cylinder (2) is coaxial and be fixed on the turning cylinder (1) with turning cylinder (1), evenly be fixed with 4-10 blade (3) on the cylinder (2), an end of turning cylinder (1) is equipped with by movable sprocket (4).
2. a kind of boiler coal feeding device as claimed in claim 1 is characterized in that turning cylinder (1) is mounted in the top of boiler traveling-grate stoker (7), coal bunker (8) coal mouth place down, and drive sprocket (6) is mounted on the chain fire-gate power transmission shaft of boiler (9).
3. a kind of boiler coal feeding device as claimed in claim 1 is characterized in that turning cylinder (1) and cylinder (2) and blade (3) are cast into one.
