Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model will be further described：
Referring to figs. 1 to Fig. 4, one kind dries mill torch firing integration Coal-disintegrating machine, including feeding machine 1, the feeding machine 1 are connected with defeated
Band 2 is sent, the end of conveyer belt 2 is connected to coal bunker 8, here in order to improve broken efficiency, more disintegrating machines 3 can be used same
Shi Jiagong, the end of conveyer belt 2 is provided with multiple hoppers 7 and coal charge is divided at most platform spiral screw rod machine 31, then passes through spiral
Screw machine 31 pushes to coal charge in the more disintegrating machines 3 and crushed, and an electronic scale is set up at each hopper 7 coal amount is carried out
Weigh, coal charge is crushed to 100-120 mesh by disintegrating machine 3, because coal charge carefully has very much potential safety hazard.In addition, in order to ensure to crush
The crushed particles standard of machine 3, the discharge end of feeding machine 1 are provided with mesh screen, allow coal charge of the diameter less than 2cm to pass through the disintegrating machine 3
End is connected to coal-powder boiler 5 by pipeline 4, also includes more air blowers 6, and every air blower 6 is connected by tracheae 61
The pipeline 4 is used to blow coal charge to the coal-powder boiler 5, the more pipelines 4 to be preferably connected to the coal dust in uniform way
Stove 5, and the more tracheaes 61 can be respectively connecting to each position of pipeline 4, and such can of air blower 6 is more effectively
Coal charge from being blown in coal-powder boiler 5.
Specifically, the top of conveyer belt 2 is covered provided with a fan housing 21, the fan housing 21 is respectively equipped with heat energy air inlet
21a and heat energy air outlet 21b, heat energy air inlet 21a are passed through hot blast, the coal charge in conveyer belt 2 are dried, and hot blast is again from warm
Energy air outlet 21b goes out, and here for the ease of obtaining hot blast, an external discharge pipe, discharge pipe can connect heat in coal-powder boiler 5
Energy air inlet 21a, as soon as setting up air-introduced machine at discharge pipe, can get hot blast easily.
In addition, in order to avoid the volume of coal dust flies away everywhere and makes working environment more clean, the outside of conveyer belt 2 is also
Being covered provided with a protection canopy 22, the fan housing 21 is located in the protection canopy 22, because coal dust easily hikes up, and coal dust pair
The health of human body influences big, and environmental pollution is serious, thus protection canopy 22 can well coal ash be interposed between conveyer belt 2 it
It is interior, in addition, in order to allow the coal ash being collected into can timely processing fall, be unlikely to accumulate in the conveyer belt 2, the bottom of protection canopy 22
Portion is connected with air blower 6 provided with more coal ash collecting pipes 22a, the every coal ash collecting pipe 22a, for by coal ash collecting pipe
Coal ash at 22a, which is blown in coal-powder boiler 5, to burn, and so both can sufficiently make use of coal charge, not cause to waste, also allow for building ring
Border is more clean.
Specifically, in order to improve the effect of drying, the outer wall of every spiral screw rod machine 31 is provided with heater 71, should add
Hot device 71 can control its maximum temperature by temperature controller.
During utility model works, the coal charge to come from feeding machine 1 enters conveyer belt 2, and the discharge end of feeding machine 1 is provided with
Mesh screen, coal charge of the diameter less than 2cm is allowed by the way that conveyer belt 2 covers conveyer belt 2 provided with fan housing 21, hot to be passed through hot blast
Wind enters from heat energy air inlet 21a, and coal charge is dried, then is come out from heat energy air outlet 21b, and the coal charge after drying falls into coal bunker
8, coal bunker 8 is delivered to coal charge in more disintegrating machines 3 by more spiral screw rod machines 31 again carries out broken processing, and the spiral spiral shell
The outer wall of bar machine 31 is heated provided with heater 71 to it, and heating, drying is carried out to the coal charge at spiral screw rod machine 31 so as to reach,
After coal charge drying, enter back into more disintegrating machines 3 and crushed, the disintegrating machine 3 the processing of coking blends into after powder, by air blower
Feeding is blowed in 6 pairs of pipelines 4, ensures that the coal charge of pipeline 4 is blowed to coal-powder boiler 5, in addition, the outside of conveyer belt 2, and it is defeated
Sending and also built a protection canopy 22 outside the workbench of band 2, protection canopy 22 has all together covered conveyer belt 2 and fan housing 21,
So that conveyer belt 2 is kept apart with other equipment, the coal ash on such conveyer belt 2, which would not blow out, to be come, but is sunk in protection canopy
22 bottom, and coal ash collecting is got up provided with more coal ash collecting pipe 22a in the bottom of protection canopy 22, can pass through air blower 6 again
Burnt in spraying toward coal-powder boiler 5, take full advantage of fuel.
The utility model conveys coal charge using conveyer belt 2, shortens the pipeline of conveying, reduces pipeline maintenance rate, also avoids
The difficulty that pipeline overhauls when blocking, while while coal charge is conveyed increase hot-air seasoning, at spiral screw rod machine 31
Increase heater 71 is dried to coal charge, and the moisture of the coal after drying is 6-8%, and coal charge moisture is low, the coal after drying
Material carries out crushing grinding, this mode by disintegrating machine 3 again, and the coal charge after crushing is not easy slagging with blocking pipeline 4, fault rate
It is low, it ensure that the efficiency of production, coal charge blow coal charge after crushing with air blower 6, air blower 6 is attached to the multiple of pipeline 4
Position, feeding efficiency is high, also reduces coal charge and accumulates within the duct 4, results in blockage, and also eliminates the coal dust storage for placing coal dust in addition
Tank is deposited, is delivered at once after coal charge grinds and burning use is carried out in coal-powder boiler, avoid potential safety hazard existing for coal dust holding vessel,
Meanwhile ball mill is not used yet, because the granular size of ball mill mill is usually to select 120-150 mesh or so, grind too thin
In the presence of the hidden danger of safety, so be typically chosen less than 200 mesh, and disintegrating machine can be milled to 100-120 mesh, for dried coal
It is already sufficiently fine for material, therefore ball mill has been saved, the cost of equipment is greatlyd save, in addition, traditional water-coal-slurry is using
When used, it is necessary to add about 50% moisture, need to vaporize water into during use, waste the energy in vaporescence, and this reality
It need not add water with new, save the energy, coal ash collecting is got up, then be burnt in spraying toward coal-powder boiler 5, make full use of fuel, work
It is good to make environment, environmental protection, beneficial to worker's health, energy-conservation, reduces field management difficulty.
The utility model examples of implementation described above are only the preferred embodiment of the utility model, not limit this with this
The practical range of utility model, therefore the change that all shape, principles according to the utility model are made, all should cover in the utility model
Protection domain in.
