Novel principal machine equipment for producing active lime

The utility model discloses a new type active lime production host device, comprising a pre-heater, a revolving furnace, a vertical cooling device, a high efficiency heat exchanger, a dust collector and other members. Material is sent into the pre-heater through the convey lifting equipment; the material is preheated to about 900 DEG C evenly by the exhausted high temperature waste gas inside the pre-heater before pushed into the revolving furnace through the hang type hydraulic push rod device; the material continues to tumble and move forward inside the revolving furnace and is tempered with 1250 DEG C high temperature; the material enters into the vertical cooling device and the temperature is lowered to less than 100 DEG C under the action of cool wind and is exhausted from the lower part of the cooling device; after cooling the material inside the vertical cooling device, the preheated air reenters the revolving furnace; waste gas preheats the material when passing through the vertical pre-heater; the waste which lowers the temperature to 320 DEG C is exhausted from the pre-heater and is sent into the high efficiency heat exchanger; pure air which exchanges heat with waste gas inside the heat exchanger is used as one-time wind and is sent back to the pre-heater; the waste gas is exhausted through the dust remover and the high temperature blower.
