Description of the drawings
Fig. 1 is the structural schematic diagram of the bauxite environment-friendly type calcining kiln of the utility model.
Reference sign：
1 --- furnace body 11 --- preheating zone
12 --- burning zone 13 --- cooling zones
14 --- combustion chamber 15 --- ring-shaped flues
2 --- feed hopper 3 --- pallets
4 --- discharge port.
Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, is not this practicality
Novel practical range limited to this.
As shown in Figure 1, the bauxite environment-friendly type calcining kiln of the present embodiment, including furnace body 1, the shape of the furnace body 1 is rotation
Swivel, upper and lower ends are smaller, and middle part is larger.The top of the furnace body 1 is provided with feed hopper 2, and the feed inlet 2 is even by certain speed
Speed feeds intake, and is provided with the refractory lining of annular in the furnace body 1 from top to bottom, between the refractory lining and furnace wall from top to bottom
It is combustion chamber 14 including preheating zone 11, burning zone 12, cooling zone 13, inside the refractory lining, refractory lining is by combustion chamber 14
It is separated with burning zone 12, heating and calcining mainly is carried out to bauxite in burning zone 12, ring-shaped flue 15 is equipped on 1 top of furnace body,
Gas after burning preheats bauxite across preheating zone 11, and then entering chimney by ring-shaped flue 15 is discharged.This reality
With new structure science, when use, is convenient, energy saving, and equipment cost is low, is especially suitable for small business.
Further, the bottom of the burning zone 12 is provided with the pallet 3 of a rotation, and the pallet 3 is provided with abrasive material mouth,
The lower section of the furnace body 1 is provided with discharge port 4, if the lower part of the furnace body 1, which is provided with from furnace wall, stretches into the combustion chamber 14
Dry burner, combustion gas ignition at burner, the raw material by calcining fall downwards with the rotation of pallet 3 from mushroom material mouth
It falls by being discharged by discharge port 4 after cooling zone 13.
Further, the burner input terminal is set on the outside of furnace wall and is connect with gas inlet pipe and combustion-supporting air hose.
Further, the ignition for igniting is equipped in the burner.
Finally it should be noted that above example is only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail to the utility model with reference to preferred embodiment, this field it is general
Lead to it will be appreciated by the skilled person that can be modified or replaced equivalently to the technical solution of the utility model, without departing from this
The spirit and scope of utility model technical solution.
