The beneficial effects of the utility model are：
1st, connected by baking oven between the two neighboring rotary furnace of series connection, the warm area of every section of rotary kiln individually can set, dried
Heat insulation structural in case, reduces gaseous exchange between each boiler tube, it is therefore prevented that high temperature furnace pipe conducts substantial amounts of heat to low temperature boiler tube, low
Warm rotary furnace is not in overheating problem, it is ensured that the sintering condition of each warm area of rotary kiln is stablized, it is achieved thereby that multi-temperature zone
Continuous sintering.
2nd, due to baking oven heat insulation structural heat insulation effect, be far longer than the heat insulation effect of independent boiler tube, so boiler tube is long
Degree identical rotary kiln, can improve the length of constant temperature warm area during series connection baking oven, and then under identical sintering process, Ke Yiti
High boiler tube rotating speed, increases the yield of stove.
