Abstract

The coal powder combustor belongs to the art of combustors. The current forge furnace applies the blower to promote combustion during coal burning. The original coal cannot be fully combusted within the furnace and will pollute the environment by its emitting black smock. The technical project of the utility model is: the fan (2) and the air bag (1), the air intake pipe (3) and the airway (25) are connected and communicated in turn. The housing (10) and refractory material layer (11) join to form a primary airway (5) and a secondary airway (4). The furnace door (6) locates at the left side of the housing (10), while fire spitting mouth (8) locates at the right side. The coal-powder spitting pipe (9) is connected with the powder exit (26) on the housing (10). On the main axis (24), the fixed plate (15), fixed hammer plate (16) and piece hammer (17) are fixed in turn. The left side of the housing (23) is equipped with intake hopper (14) and fixed storage hopper (13), while the right side of the housing (23) is installed with fans (22) in correspondence with coal-powder exit (26) on the housing (23). The advantages of the combustor are: the machine is capable of grinding the original coal with the size smaller than 20 mm into tiny powders which can be injected into the furnace to be fully combusted, with small coal consumption but high heat efficiency.

Description

The coal dust firing machine

Technical field: the utility model relates to the combustor technical field, is the coal dust firing machine more specifically.

Background technology: it is combustion-supporting with the air blast air blast that existing forge furnace burns coal, and raw coal can not fully burn in stove, and coal consumption is big, and the thermal efficiency is lower, the over-emitting black exhaust contaminated environment.

Summary of the invention: for overcoming above-mentioned shortcoming, the purpose of this utility model is a kind of coal dust firing machine of design.Its technical scheme is: blower fan 2 is connected with bellows chamber 1 and communicates, bellows chamber 1 is connected with blast pipe 3 and communicates, be provided with refractory masses 11 in the shell 10, form air channel 5 and secondary air duct 4 by shell 10 and refractory masses 11, blast pipe 3 is connected with air channel 25 and communicates, viewport 7 is arranged on the shell 10, and shell 10 left ends are fire door 6, and its right-hand member is a bocca 8; Have coal-ash spraying tube 9 on the shell 10, pipeline 12 1 ends connect coal-ash spraying tube 9, and its other end connects discharge 26; Main shaft 24 supports and passes housing 23 by bearing block 21, on main shaft 24, be fixed with fixed disk 15, fixedly hammer coils 16 fixedly connected fixed disks 15, be provided with liner plate 18 in housing 23, housing 23 is provided with removes gate 19, is provided with feed hopper 14 at housing 23 left ends, be fixed with hopper 13 on the feed hopper 14, fan 22 and corresponding with the discharge 26 on being contained in housing 23 is housed in housing 23 right parts, and main shaft 24 right-hand members are equipped with belt pulley 20, and fixedly hammer coils 16 fixedly connected hammers 17.The advantage of this utility model is: the reasonable in design practicality, novelty is skillfully constructed, this machine can spray in the stove uniformly and burns fully wear into fine powder less than 20 millimeters raw coal, coal consumption is little, thermal efficiency height, with burn raw coal and compare and can save 30～50%, be applicable to various smouldering fire kilns, dry by the fire fiery kiln, annealing furnace, boiler, reverberatory furnace etc., the air-supply guide frame of speaking out of turn with particular design, can effectively form the heat build-up high-temperature region, it exchanges with the radiation eddy current type, has fundamentally changed fixedly shape coal-fired fuel situation.

Description of drawings: this accompanying drawing is the utility model structural representation.In the accompanying drawing: 1, bellows chamber, 2, blower fan, 3, blast pipe, 4, secondary air duct, 5, air channels, 6, fire door, 7, viewport, 8, bocca, 9, coal-ash spraying tube, 10, shell, 11, refractory masses, 12, pipeline, 13, hopper, 14, feed hopper, 15, fixed disk, 16, fixing hammer dish, 17, the sheet hammer, 18, liner plate, 19, remove gate, 20, belt pulley, 21, bearing block, 22, fan, 23, housing, 24, main shaft, 25, the air channel, 26, discharge.

The specific embodiment: blower fan 2 is connected with bellows chamber 1 and communicates, bellows chamber 1 is connected with blast pipe 3 and communicates, be provided with refractory masses 11 in the shell 10, form air channel 5 and secondary air duct 4 by shell 10 and refractory masses 11, blast pipe 3 is connected with air channel 25 and communicates, viewport 7 is arranged on the shell 10, and shell 10 left ends are fire door 6, and its right-hand member is a bocca 8; Have coal-ash spraying tube 9 on the shell 10, pipeline 12 1 ends connect coal-ash spraying tube 9, and its other end connects discharge 26; Main shaft 24 supports and passes housing 23 by bearing block 21, on main shaft 24, be fixed with fixed disk 15, fixedly hammer coils 16 fixedly connected fixed disks 15, be provided with liner plate 18 in housing 23, housing 23 is provided with removes gate 19, is provided with feed hopper 14 at housing 23 left ends, be fixed with hopper 13 on the feed hopper 14, fan 22 and corresponding with the discharge 26 on being contained in housing 23 is housed in housing 23 right parts, and main shaft 24 right-hand members are equipped with belt pulley 20, and fixedly hammer coils 16 fixedly connected hammers 17.After treating that the combustor internal combustion is normal, start blower fan 2 and main shaft 24 rotations, it is interior after three grades of pulverizing that coal particles enters housing 23 by hopper 13 and feed hopper 14, coal dust blows out through pipeline 12 and coal-ash spraying tube 9 from discharge 26 by fan 22 and enters in the combustor, under the eddy current wind effect that air channel 5 and secondary air duct 4 produce coal dust is fully burnt and by bocca 8 flame in the heating stove metal processing piece in the stove is heated.
