The complete set of equipment for sludge treatment organic fertilizer production line has a compact process layout, scientific rationality, advanced technology, energy saving and consumption reduction, no three emissions, stable operation, reliable operation, easy maintenance, and wide adaptability to raw materials. Adapting to various ratios of organic compound fertilizers, bio organic fertilizers, urban sludge, and household waste organic fertilizers has filled the domestic gap and reached the leading level in China. It is a promotion project of practical environmental protection technology in China. Livestock manure is rich in organic matter, which can provide the nutrients needed for crop growth and improve soil fertility. There are various types of organic fertilizers, with a wide range of raw materials and a variety of fertilizers.
Equipment process of sludge treatment organic fertilizer production line:
1、 Mix feces with an appropriate amount of straw powder, and the amount added depends on the moisture content of the raw materials. Generally, fermentation requires a moisture content of 45, which means that the dough should be kneaded by hand, with water visible between the fingers but not dripping. Release the dough and it will disperse. Then add cornmeal and bacterial strains. The purpose of cornmeal is to increase sugar content for bacterial fermentation, allowing multi-dimensional complex enzyme bacteria to quickly gain an advantage.
2、 Add the prepared mixture to the mixer and stir it thoroughly without leaving any lumps.
3、 The mixed ingredients are stacked into long strips with a width of 1.5-2 meters and a height of 0.8-1.0 meters, and thrown every 2 days using a flipping machine.
4、 Stacking takes 2 days to heat up, 4 days to be odorless, 7 days to loosen, 9 days to become fragrant, and 10 days to become fat.
- On the second day of stacking, the temperature can reach 60 ℃ -80 ℃, killing diseases and pests such as Escherichia coli and insect eggs;
- On the the fourth day, the odor of feces was eliminated; On the seventh day, the compost became loose and dry, covered in white mycelium;
- On the ninth day, a wine yeast aroma was emitted;
- On the tenth day, the bacterial fertilizer fermented and matured.
5、 After a little drying, it can be crushed by a semi wet material crusher, granulated by an organic fertilizer granulator, dried and dehydrated by a dryer, and then screened by a screening machine. The finished organic fertilizer is ready and can be packaged and stored.
Processing technology of sludge organic fertilizer production line
Pre-treatment process
Collect feces and urine, mix them with hay and decaying silage to make compost, and let it ferment. When fermenting and planting, use a composting machine to fully ferment the feces. Only timely and uniform composting can achieve this. Some places are very dry and some places are very wet now, which can affect the quality of fermentation.
Grinding process
the material will be transported to grinder for grinding, iron-remover will be equipped before grinder.
Mixing process
The composted materials, inorganic fertilizers such as N, P, K, and other additives are crushed, proportioned, and mixed in a certain proportion through a material crusher and a horizontal mixer using a batching bin.
Granulation
Adopting a new type of organic fertilizer granulator to granulate materials.
adopt dedicated organic fertilizer ring die pellet mill with the suitable linear velocity, high accuracy gear driven pellet mill has higher driving efficiency, ring die is quick-loaded clamp type
Screening and return system
The granular materials output from the granulation molding system have certain differences in particle size and need to be screened and classified. The selected rotary screening machine requires low vibration, low noise, easy screen replacement, and is equipped with a screen surface cleaning device. It is recommended to equip an automatic material return system to screen the unqualified large and small particle materials, which are then transported out through a belt elevator, re crushed, and sent to the granulator for further granulation. This will help improve the continuous operation capacity of the production line.
fertilizer dry
use an organic fertilizer dryer to further remove moisture from the screened particles to meet the standard requirements for organic fertilizer moisture content.
cooling
Cooling granular materials with a cooling machine helps to preserve their quality during storage
packing
The cooled granular materials from the organic fertilizer equipment are transported into the finished product warehouse through a bucket elevator. Particle materials are quantitatively weighed and packaged using an automatic packaging scale
