The innovations that the present invention possesses:

1. Fully automatic operation control The batching adopts PLC control system, touch screen operation, automatic weighing, uniform batching, and accurate measurement, which greatly reduces the labor intensity of workers, reduces labor, improves the working environment, and enables the lime kiln to realize digitization Management, automation control. The system has two kinds of automatic transmission and manual transmission, which are easy to operate. 2. Loading by counterweight truck, uniform feeding, and rotating fixed-point distribution. The raw material limestone and fuel coal are prepared in proportion and fully mixed with special equipment under the kiln. The distributor divides the material surface of the vertical kiln into 4 small blocks, 3 line surfaces and 7 point surfaces for uniform distribution, so that the material surface in the kiln is uniform, which plays a key role in the stability of calcination. 3. Reasonable air supply, sealed ash (1), reasonable air supply: During the calcination process of the active lime shaft kiln, the size of the air supply and the uniformity of the air distribution are crucial to the output and quality of the lime, such as uneven air supply There will be partial burning, so that over-burning and raw burning will occur, which will greatly affect the quality of lime. The air supply system designed by our company is to send the air through the blower into the square air chamber and the air supply channel into the energy-saving pressure equalizing air cap designed by our company to enter the kiln with equal pressure and volume. The equal pressure air cap can ensure the scientific combustion air. Layered distribution to the section of the furnace material in the kiln, so that the air flow in the kiln is evenly distributed, the flame combustion intensity is consistent, the air flow and air pressure distribution are scientific and reasonable, and the activity of lime production and the production output of lime kiln are effectively improved. (2) Sealing and uniform ash discharge: After the lime is calcined in the vertical kiln and then placed in the cooling zone, it must be cooled in time, and the ash temperature can be lowered to about 50 degrees before the ash can be released, so that the air volume blown into the kiln is strictly controlled. In order to ensure the effective air volume blown into the kiln, it can meet the cooling requirements. The lime shaft kiln ash unloading device of our company adopts the method of dividing the kiln bottom material surface into 4 sides, and discharges the ash through four drawer-shaped ash removal machines to the small ash bin connected with the kiln body, and then uses the hydraulic plug-in valve to match the vibration. The ash discharge by the ash unloading machine ensures that the material surface of the shaft kiln is evenly lowered from the surface, and at the same time ensures the sealing of the kiln bottom, which saves fuel and electricity consumption.
