Description
Technical Field
The invention relates to the technical field of feeding devices, in particular to a fully-sealed double-hearth kiln feeding device.
Background
The double-chamber kiln is advanced lime calcination equipment, and has two vertical kiln chambers, and two connecting channels are arranged at the middle lower part of the kiln body to connect the two kiln chambers. The double-hearth kiln calcination process has two main characteristics: parallel flow and heat storage. Co-current is the downward flow of combustion products along with the limestone as it is calcined, which facilitates the calcination of high quality active lime. The heat accumulation is that when the kiln chamber A is calcined, the calcined product, namely high-temperature flue gas, enters the kiln chamber B through two connecting channels at the middle and lower parts of the kiln chamber. After entering the kiln chamber B, the high-temperature flue gas flows upwards to preheat the limestone in the preheating zone to a higher temperature, and the process is equivalent to storing the heat of the flue gas in the preheating zone of the kiln chamber B.
At present, smoke dust is generated when an original dust removing pipeline falls from a weighing hopper to a kiln top reversible belt conveyor or when a feeding trolley is used for feeding to the kiln top weighing hopper in the whole feeding system of the double-hearth lime kiln, and a large amount of smoke dust is generated in the process of rotating and lifting from the kiln top reversible belt to a rotary distributor material cup.
