starting theflame burner 70, further leading theflame nozzle 79 to continuously jet combustion flame, and under the drainage action of thedrainage cone 78, the flame jetted from theflame nozzle 79 expands into thefurnace chamber 76 in a trumpet shape; at the moment, a synchronous wheel motor is started, the synchronous wheel motor drives asynchronous wheel 19 to continuously rotate through a synchronous belt, so that the smoke guidestraight pipe 6 rotates together, the left smoke guide straight pipe 6.1 is in a continuous rotation running state, the rotation of the left smoke guide straight pipe 6.1 drives eachrectangular disturbance blade 77 to generate continuous disturbance in thefurnace chamber 76, further, flame gas in thefurnace chamber 76 is fully dispersed, and further, the air heatingspiral pipe 73 is uniformly heated by the flame gas; at this time, thecentrifugal booster blower 86 is started, so that the booster air continuously flows through the air heatingspiral pipe 73, the booster air continuously flowing through the airheating spiral pipe 73 is continuously heated by the first section of the flame gas in thefurnace chamber 76, and the air heated in the airheating spiral pipe 73 is continuously introduced into the hotair transition pipe 13, so that the feeding of the high-temperature air is realized; meanwhile, high-temperature flue gas generated by the combustion flame in thefurnace chamber 76 is continuously introduced into the hot fluegas introduction passage 3 through the plurality of hot fluegas introduction holes 74 under the action of the furnace chamber air pressure, so that hot flue gas supply is realized.

The dehydration of the dehydration cylinder comprises the following specific steps and processes:

step one, avalve 28 on adischarge pipe 20 is closed, a synchronous wheel motor is started, the synchronous wheel motor drives asynchronous wheel 19 to continuously rotate in the forward direction through a synchronous belt, atransmission shaft 7, a spiralhollow transmission blade 8 and a smoke guidestraight pipe 6 rotate together, then wet organic fertilizers mixed well by an organicfertilizer mixing device 81 are discharged to afeed pipe 17 and are led into an organicfertilizer conveying channel 1, the wet organic fertilizers entering the organicfertilizer conveying channel 1 are gradually pushed to the right to roll under the continuous stirring and propelling action of the spiralhollow transmission blade 8, and when the wet organic fertilizers are dispersed in the whole organicfertilizer conveying channel 1, the wet organic fertilizers are temporarily led into thefeed pipe 17;

step two, controlling a synchronous wheel motor to periodically rotate in a positive and negative intermittent mode, further enabling the spiralhollow transmission blades 8 to continuously and intermittently rotate in a positive and negative mode, further enabling wet organic fertilizers in the organicfertilizer conveying channel 1 to be in a continuous stirring and rolling state, enabling the organic fertilizers in the organicfertilizer conveying channel 1 to be continuously fluffy and breathable, and continuing the stirring and rolling state in the organicfertilizer conveying channel 1 to step four;

thirdly, the dehydrationcombustion heat source 72 starts to operate, high-temperature flue gas generated by combustion flame in thefurnace chamber 76 is continuously led into the hot flue gas leading-inchannel 3 through a plurality of hot flue gas leading-inholes 74 under the action of the air pressure of the furnace chamber, the high-temperature flue gas in the hot flue gas leading-inchannel 3 is continuously led into the spiral left end of the flue gas leading-outheat exchange channel 4 through a plurality of left flue gas leading-in holes 5, the high-temperature flue gas in the flue gas leading-outheat exchange channel 4 continuously flows along the spiral right direction of the spiralhollow transmission blades 8 until the flue gas at the right end of the flue gas leading-outheat exchange channel 4 is continuously led out to the cold fluegas discharging channel 14 through a plurality of right flue gas leading-outholes 21, and the flue gas continuously led out to the cold fluegas discharging channel 14 is discharged through the; in the process, high-temperature smoke continuously flows through the smoke guide andheat exchange channel 4, and the spiralhollow transmission blade 8 with the thin-wall hollow structure is in a continuous high-temperature state under the action of heat conduction; the wet organic fertilizer in the organicfertilizer conveying channel 1 is continuously heated by the wall body of the spiral hollow conveyingblade 8 under the condition that the wet organic fertilizer is continuously stirred and rolled, so that the wet organic fertilizer in the organicfertilizer conveying channel 1 is continuously heated, the water volatilization phenomenon occurs, and water vapor is formed in the organicfertilizer conveying channel 1;

because the spiralhollow transmission blade 8 positioned between thetransmission shaft 7 and the smoke guidestraight pipe 6 divides the air secondsection heating channel 2 into spiral channels, part of heat on the spiralhollow transmission blade 8 can be also conducted into the spiral channels formed in the air secondsection heating channel 2, and then the gas flowing through the spiral channels formed in the air secondsection heating channel 2 is heated;
