Description
Technical field
The utility model is related to a kind of ball mill heating plants, belong to ball mill heating equipment technical field.
Background technology
Currently, the heating system of ball mill is directly to draw hot wind out of hot-blast stove by air-heater, it is then delivered to ball milling
In machine.Air-introduced machine is opened too big, invites hot wind just to have many sparks from hot-blast stove, and spark be easy to cause explosion into ball mill,
It is abnormally dangerous；Air-introduced machine is opened too small, and hot wind is with regard to not enough.And wind pressure of the hot wind when entering ball mill is positive pressure, wind pressure
It is too big, it is easy to run wind, positive pressure also results in raw material and enters mill difficulty, is frequently occluded.
Utility model content
The utility model aim is to provide a kind of ball mill heating plant, can facilitate the adjusting of hot wind, ensure hot wind
Supply, avoids the occurrence of spark, solves the problems, such as background technology.
The technical solution of the utility model is：
A kind of ball mill heating plant, including hot-blast stove, coal mill hot air duct, ball mill, hot-blast valve, cold blast sliding valve, air inducing
Machine, dust-precipitator, raw coal feed opening and Vertical Mill hot blast pipe, hot-blast stove are equipped with hot-blast outlet, the hot-blast outlet of hot-blast stove respectively with coal
Mill hot air duct is connected with one end of Vertical Mill hot blast pipe, and the other end of Vertical Mill hot blast pipe is connect with vertical mill, and coal grinds hot air duct
The other end and the entrance of ball mill connect, the outlet of ball mill is equipped with dust-precipitator and air-introduced machine, on the coal mill hot air duct
It is equipped with hot-blast valve, cold blast sliding valve and raw coal feed opening successively according to the direction of air-flow.
The coal grinds entrance of the raw coal feed opening on hot air duct close to ball mill.
Burner is equipped in the hot-blast stove.
The burner is located at the top of hot-blast stove.
The coal mill hot air duct is connect by cold blast sliding valve with cold air duct.
Using the utility model, the heat that hot-blast stove generates uses simultaneously for vertical mill and ball mill, and burner is in hot wind
The heat that burning generates in stove is entered in ball mill under the action of air-introduced machine by coal mill hot air duct, since air-introduced machine is pacified
Mounted in the outlet of ball mill, the wind pressure for avoiding ball mill from sucking a large amount of spark, and entering ball mill is negative pressure, under convenient
Material.The hot blast rate that ball mill needs can be controlled by hot-blast valve.When ball mill outlet when the temperature is excessively high, cold wind can be passed through
Valve is appropriate to mix cold wind into coal mill hot air duct, to reduce the temperature of hot wind.
The utility model has the beneficial effects that：The adjusting that hot wind can be facilitated ensures the supply of hot wind, ball mill is avoided to inhale
Enter a large amount of spark to set off an explosion, and ensures that the wind pressure into ball mill is negative pressure, facilitates blanking.It is simple in structure, operation spirit
It is living.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
In figure：Hot-blast stove 1, coal mill hot air duct 2, ball mill 3, hot-blast valve 4, cold blast sliding valve 5, air-introduced machine 6, dust-precipitator 7, original
Coal feed opening 8, burner 9, Vertical Mill hot blast pipe 10.
Specific implementation mode
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
With reference to attached drawing 1, a kind of ball mill heating plant, including hot-blast stove 1, coal mill hot air duct 2, ball mill 3, hot-blast valve
4, cold blast sliding valve 5, air-introduced machine 6, dust-precipitator 7, raw coal feed opening 8 and Vertical Mill hot blast pipe 10, hot-blast stove 1 are equipped with hot-blast outlet, hot wind
One end that the hot-blast outlet of stove 1 grinds hot air duct 2 and Vertical Mill hot blast pipe 10 with coal respectively is connect, the other end of Vertical Mill hot blast pipe 10
It is connect with vertical mill, the other end of coal mill hot air duct 2 is connect with the entrance of ball mill 3, and the outlet of ball mill 3 is equipped with dust-precipitator
7 and air-introduced machine 6, it is equipped with hot-blast valve 4, cold blast sliding valve 5 and raw coal blanking successively according to the direction of air-flow on the coal mill hot air duct 2
Mouth 8.
In the present embodiment, hot-blast stove 1 is common hot-blast stove in the art, and the top in hot-blast stove 1 is equipped with combustion
Burner 9.Coal grinds the raw coal feed opening 8 on hot air duct 2 close to the entrance of ball mill 3, facilitates raw coal to enter in ball mill 3, ball
Grinding machine 3 can be commercially.
The heat that hot-blast stove generates uses simultaneously for vertical mill and ball mill, and the burning in hot-blast stove 1 of burner 9 generates
Heat is entered in ball mill 3 under the action of air-introduced machine 6 by coal mill hot air duct 2, since air-introduced machine 6 is mounted on ball mill 3
Outlet, avoid ball mill from sucking a large amount of spark, and the wind pressure for entering ball mill is negative pressure, facilitates blanking.
Air quantity can be controlled by installing hot-blast valve 4 additional on coal mill hot air duct 2, install cold blast sliding valve 5 additional, appropriate can be mixed cold
Wind, to reduce the temperature of hot wind.Wind pressure into ball mill 3 can meet needs by adjusting air-introduced machine 6.
By reconciling burner 9 and hot-blast valve 4 and cold blast sliding valve 5 in hot-blast stove 1, the inlet temperature of ball mill 3 is made to reach
To 200 degree, meet production needs.When needing plus producing, the temperature negative pressure in ball mill 3 will change, and need to improve air quantity,
But the outlet temperature of ball mill 3 meets ball mill 3 no more than 60 degree by adjusting air-introduced machine 6, hot-blast valve 4 and cold blast sliding valve 5
Outlet temperature, improve the flexibility of system operatio, system made to be easier to control.
