It has the characteristics of compact structure, low energy consumption, stable operation, high degree of automation, and good solid-liquid separation effect. Using this machine to treat pig manure and sewage, the removal rate of suspended solids can reach more than 90%, and the moisture content of the excrement residue after squeezing is less than 60%, which will not cause secondary pollution. The feces residue can be directly packaged and transported to continue to make fertilizer for use It can also be used as fish bait for fish farming, etc. It is suitable for use in harsh environments with high humidity and strong corrosion. It is a new generation of environmental protection equipment for manure treatment. The inclined screen solid-liquid separator has complete functions and strong pertinence. The design of the whole machine organically combines the manure pumping system, vibration system, slag feeding extrusion system and automatic flushing system, which improves the sewage treatment capacity and treatment effect. And can squeeze dung to be convenient to utilize, have creativity.
