Wind turbine, one Room of cold wind top set front end to tilt fixed bed, and grate-cooler and cold wind set refractory baffle, refractory baffle between one Room
Feed opening is reserved between tilting fixed bed with front end, dump skip is set below feed opening, turnover panel air valve is set below dump skip；
During production, after metering of the lime stone by feeding metering device, lifting hopper is discharged into by feed opening, lifting hopper passes through lifting
When machine is run to top, lifting hopper discharges lime stone when corresponding to the top feed inlet of lime shaft preheater, and lime stone is sent
Enter in lime shaft preheater；Meanwhile kiln temperature is heated up to 1300 DEG C~1400 DEG C by the burner for turning round kiln hood.
Rotary kiln is sent at least 1000 DEG C of hot gas in lime shaft preheater by the pipeline of afterbody, and lime is vertical pre-
Lime stone in hot device is discharged into rotary kiln after lime stone preheating by pipeline by 1000 DEG C of preheating, by 1300 DEG C~
1400 DEG C of kiln temperature is calcined.
Decomposition of limestone is discharged into lime, lime by kiln hood after calcining, is subject to refractory baffle to stop the grate-cooler entered
A Room, the cooling that lime passes through one Room cooling blower cold wind of grate-cooler.
When the temperature of lime is reduced to less than 100 DEG C, the lime entered by discharge port in bottom discharge bucket, dump skip leads to
Turnover panel air valve is crossed to be transported in warehouse for finished product.
Beneficial effect：The purpose of the present invention is by using existing clinker line, increase feeding metering device, lifting
Machine, lime pre-heater, after transforming existing grate-cooler, utilize the part equipment and facility of existing clinker line, so that it may
Utilization rate of equipment and installations is improved to produce the lime of qualification, increases Business Economic Benefit.
