NOVELTY - Ash fertilizer firing device comprises a burning kiln, a feeding device and a smoke purifying device. A burning inner cavity is arranged at the burning kiln. The burning kiln is oblique, and the angle between the burning kiln and the horizontal plane is 10-60 degrees . A transmission shaft driven by a main motor is arranged in the burning inner cavity. Multiple material dispersing bodies for stirring materials are arranged on the transmission main shaft. An air inlet, a smoke outlet, a feeding opening and a material clearing opening-closing door are arranged on the burning kiln.    USE - Used as ash fertilizer firing device.    ADVANTAGE - The ash device has good separating effect, removing of solid particles and dust in smoke, realizes firing of wheat straw in concentrating mode and ensures stable firing, produces high purity ash fertilizer, and avoids pollution.    DETAILED DESCRIPTION - Ash fertilizer firing device comprises a burning kiln, a feeding device and a smoke purifying device. A burning inner cavity is arranged at the burning kiln. The burning kiln is oblique, and the angle between the burning kiln and the horizontal plane is 10-60 degrees . A transmission shaft driven by a main motor is arranged in the burning inner cavity. Multiple material dispersing bodies for stirring materials are arranged on the transmission main shaft. An air inlet, a smoke outlet, a feeding opening and a material clearing opening-closing door are arranged on the burning kiln. The feeding device comprises a feeding cylinder and a feeding auger. A part of the feeding cylinder is connected with the feeding auger. The diameter of the feedstock within the feeding port from the feeding auger is gradually reduced. The dust-cleaning device comprises smoke outside channel, water tank. The smoke outside channel is connected with smoke discharge port. The smoke outside channel in the upper part is provided with a shower of water head. The smoke exhaust channel and falling pool is connected to outside. The bulk body is provided with multiple fire-leading through hole. The transmission main shaft axis of the ignition is arranged in parallel.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the ash fertilizer firing device.
