(6) preparation of fermentation material

The fermentation material is prepared by mixing 70% of human and animal manure (or 50% -60% of human and animal manure and 10% -20% of sewer sludge, and a mixture) with 25% of the above-mentioned 1 crop straw powder (sawdust) and 5% of animal internal organ meat paste. The method comprises digging human and animal feces with an excavator, slowly pouring into a hopper 4 of a running firewood type pulverizer (in the invention, an automatic water and residue removing port 14 must be additionally arranged), gradually pulverizing human and animal feces by impact and splitting force with a hammer 3, blowing the pulverized human and animal feces with a fan 2, feeding into a separator 6 from a powder outlet pipe 13, and rotating a turbine blade 7 in the separator at a certain speed to separate coarse powder from fine powder. The coarse powder returns to the feeding hopper through the return pipe 5 to be crushed again, and the fine powder escapes from the fine powder discharging device 9 and is conveyed to the feeding port of the double-screw mixer by the conveyor belt. Once the digging shovel is crushed, the material slag is discharged once so as to prevent sundries such as stones, iron blocks and the like doped in the material slag from damaging the hammer. The discharged material slag can be conveyed to a manual material selecting field by a conveyor belt, and sundries such as bricks, stones, iron blocks and the like are removed by tools such as rakes and the like manually and then are concentrated and recharged for crushing. The pulverizing fineness of the firewood-field pulverizer (also called universal pulverizer) is adjusted by the wind speed of the fan, and the powder is coarse when the wind speed is high, and the powder is fine when the wind speed is not high. In actual production operation, the wind speed of the fan should be adjusted to the standard that stones and bricks doped in excrement cannot be blown into the wind pipe 13. The machine is characterized in that the grinding granularity is adjustable, micro-manure grains with the grain diameter of 0.1-0.2cm and macro-manure grains with the grain diameter of 1-2cm can be produced, the fermented material which is agglomerated into sticky blocks in the preparation of the rear water-storage organic fertilizer grains can be dehydrated and then ground, the purposes of removing impurities and dehydrating the animal manure can be achieved in the grinding process, the machine can not only grind the animal manure, but also grind crop straws, and the machine is multipurpose. The 25% of the crop straw powder (or sawdust) and 5% of the livestock internal organ minced meat of the 1 are sequentially added into a double-helix mixer, then the double helix lifts the manure particles, the crop straw powder and the livestock internal organ minced meat from bottom to top to form two symmetrical rotating column material flows which rise along an arm, the rotating arm drives the screw to revolve, so that the material outside the screw is correspondingly mixed into the screw column material body, and the material in the cone body is continuously mixed and dislocated. The materials are converged by the center of the conical body and flow downwards, so that the materials can be uniformly mixed in a short time, the uniformly mixed manure particles, crop straw powder and livestock viscera meat paste mixture are discharged into a dump truck below through a discharge port, the dump truck is pulled to the side of a fermentation tank and poured into the fermentation tank, and the mixture has a little moisture. The double-helix mixer has the characteristics of uniform mixing, continuous production, and mixing of fermentation materials and water storage organic fertilizer ingredients by using the double-helix mixer.
