Gear Transmission of Magnesium Rotary Kiln and Its Smoothness


At the big gear of magnesium rotary kiln body, the transmission is stopped by synchronous motors on both sides. There are two small gears meshing with the big gear. This kind of transmission point is more, the operation is stable, the force of tooth is reduced by half, the modulus and width of gear can be greatly reduced, which is conducive to the arrangement of equipment. Both sides of the transmission will also constitute too many parts, increasing the amount of equipment and maintenance work. There are automatic fuel injection nozzles on both sides of the tooth surface to stop fuel injection smoothly.

The waste oil from the smooth magnesium rotary kiln is pumped and pressurized and sent to the cooler. The original oil pipe was on the river side, but now it is on the mountain side. The main reason is that there is more heat dissipation on the river side, and the ambient temperature will be relatively low, which will increase the viscosity of the smooth oil of the rotary kiln. In addition, it is necessary to take care of pedestrians on the riverside, which increases the circuitous resistance of the oil pipeline. I personally think that it is not very good to put the waste oil into the cooler to extinguish. At the beginning of the cooler, the clinker should be cooled, and no heat is expected to enter. Adding the waste oil to the cooler for quenching will move the temperature in the cooler and affect the cooling power of the clinker. The waste oil will be introduced to the heat demand places, such as preheaters, kilns and other places.

The smooth oil and pump of rotary kiln equipment are all in the house under the kiln base, so the rotary kiln equipment is arranged to make the site cleaner and the ambient temperature of smooth equipment is lower. Pump is the use of air compressor as power, the compressed air from the air compressor is first filtered by a filter to remove water. And then it pays dividends in two ways. The metal magnesium rotary kiln equipment is connected with an electromagnetic oil pressure control valve at the nozzle of the upper gear. The other way is the pump into the oil barrel. There is a pressure gauge, an oil tank and a pressure relief valve connected in series on the pipeline. After the compressed air passes through the oil tank, it can make a part of the oil in the air pump and smooth the pump. The operation of the pressure relief valve is controlled by the solenoid valve at the nozzle. When the pressure on the oil circuit is higher than 8 bar, the solenoid valve will sense a signal to let the relief valve relieve pressure. At this time, the compressed air can not enter the oil barrel to pressurize, and the magnesium rotary kiln air compressor stops working. When the oil pressure is lower than 6 bar, the air compressor will start again. After the oil comes out of the oil barrel, it passes through a pressure gauge, and there is an overload maintenance valve on the pipeline. At the end of the nozzle, the air in the air pipe is used to eject the oil, and the remaining oil will return to the oil barrel from the nozzle through the return pipe. There are four groups of parallel nozzles on a tooth surface. Only one nozzle is sprayed each time, and then the oil injection in turn is stopped.
