If the manure of pig farm is not properly treated, not only the surrounding soil, water and air can be seriously polluted, but also a large number of bacteria can be bred, which threatens the health of human and livestock.

[0003] When the pig manure is in a relatively dry state, its texture becomes hard and has certain viscosity, which is easy to form blockage in the key parts such as the feed inlet, spiral blade and filter screen of the spiral dewatering machine. When the water content in the pig manure is too high, the high water content makes the pig manure present a relatively thin state, and the friction between the material and the spiral blade in the spiral dewatering machine is reduced, which is prone to skidding.

[0004] The reason for this problem is that the dry pig manure particles adhere to each other, which is difficult to move smoothly along with the rotation of the spiral blade, resulting in material accumulation, and even the motor of the spiral dewatering machine is overloaded, causing equipment failure and shutdown. Frequent cleaning and maintenance not only consumes a lot of manpower and material resources, but also greatly reduces the manure treatment efficiency. The water content of the treated pig manure is still too high, which cannot meet the requirements of subsequent resource utilization such as composting and biogas production.
