3The raw coal energy consumption).Because (being the large cylinder shape) difficult processing directly influenced the output and the quality of haydite after the haydite pellet knot bulk.
The main cause of forming the cylinder bulk, the one, pellet is after rotary kiln end is knocked down, because pellet runs into cylindrical shell high temperature (cigarette vapour mixture) suddenly the pellet surface moisture is increased sharply, be in the extruding stacking states between the pellet, inter-adhesive, be easy to generate the large cylinder caking, the 2nd, roll to the kiln tail under the external force effect equidirectional at cylindrical shell, that bring with the speed rotation of established caking in the cylindrical shell, the cylinder caking is more and more tighter, more and more solid.When this cylinder bulk enters the roast stage, still shape remains unchanged, up to moving to kiln tail place, and still big caking shape.If bigger caking blocks in the kiln body, deal with the comparison difficulty, also can directly influence normally carrying out of production.
The purpose of this utility model provides the energy-conservation enough differentials of a kind of cylindrical shell merogenesis, each cylindrical shell and along the rotary kiln of counter-rotating, and the rotating speed by the application cylinder body segment, direction of rotation etc. make the individual particle spheroid be loose shape prevented from caking.
The purpose of this utility model is to realize like this, a kind of cylindrical shell merogenesis rotary kiln, contain charging device, cylindrical shell, device for discharging and igniter, its middle cylinder body is made up of two (comprising two) above cylindrical shell joint, from the charging device to the device for discharging, the diameter of cylindrical shell joint increases successively, top cylindrical shell joint is tightly connected with charging device, rearmost cylindrical shell joint is tightly connected with device for discharging, connection between the cylindrical shell joint is injected the bigger cylindrical shell section header portion of diameter by successively that diameter is less cylindrical shell joint afterbody and is realized, at cross section, leave the space between the outside of afterbody and the inboard of head, on each cylindrical shell joint two rolling rings are arranged all, a gear ring, gear ring is between two rolling rings, supporting and positioning device is lived the cylindrical shell joint by two rolling ring supporting ﹠ stablizings, and transmission device drives the cylindrical shell joint by gear ring and rotates freely around the common center axle of all cylindrical shell joints.
In the above-mentioned technical scheme, the cross section of interconnective cylindrical shell joint, the purpose that leaves the space between the bigger cylindrical shell section header portion inboard of the less cylindrical shell joint afterbody outside of diameter and diameter is to guarantee that two cylindrical shells joints can rotate freely independently of one another.
The utility model is because different cylindrical shell joint can differential and along reverse rotating freely, so the energy-conservation haydite pellet that enough allows of different cylindrical shells is made differential and along reverse motion in cylindrical shell, makes that the individual particle ball is loose and is difficult for adhesion.The kiln hood part rotating speed of cylindrical shell is fast, and the haydite pellet is difficult for adhesion, and kiln tail zone of swelling section diameter is big, volume is big, rotating speed is slow, and the abundant spontaneous combustion of haydite spontaneous combustion matter under the effect of flyash haydite swelling and curing agent, is finished the sintering overall process.
