Discharge auger, and the kiln outer cylinder is internally provided with spiral inner cylinder, and feeding auger is arranged on the inner wall of the spiral inner cylinder,
The revolving fragment of the feeding auger is right spiral setting processed, the flight rotation side of the feeding auger and outer discharging auger
To being reversed, the left end of the kiln outer cylinder is provided with feed inlet, feed inlet protrude into the setting of spiral inner cylinder and with kiln outer cylinder it
Between closed setting, the spiral inner cylinder right end setting outer cylinder between material conveying communicating passage, the kiln outer cylinder
Left part be additionally provided with discharge port, the right end of closed setting between discharge port and spiral inner cylinder, the kiln outer cylinder is provided with
Air intake passage is provided with air blower on air intake passage.
Specifically, the big sprocket wheel is end to end chain.
Specifically, being fixedly connected between the kiln outer cylinder and spiral inner cylinder by holding screw.
Specifically, the air intake passage is connected to kiln outer cylinder and spiral inner cylinder simultaneously.
The beneficial effects of the utility model are: being the improvement carried out to existing rotary kiln, including in kiln outer cylinder and spiral
Cylinder, is arranged material conveying passage between kiln outer cylinder and spiral inner cylinder, material enters spiral inner cylinder by feed inlet and carries out rotary heating
Then process enters the cavity between kiln outer cylinder and spiral inner cylinder by transfer passage, after carried out being mixed into discharging by discharging auger
Mouthful output, not only reduces thermal loss, and from spiral inner cylinder again to kiln outer cylinder, extends heating and discharge time, and two layers
The setting of cylinder can reduce the loss of heat, take full advantage of heat.The utility model simple, energy saving, cost with structure
The advantages of reduction, small investment.
