efficiency, simple operation, convenient installation and maintenance, etc. It can separate the raw manure water of livestock and poultry excrement into liquid organic fertilizer and solid organic fertilizer. Liquid organic fertilizer can be directly used for crop absorption and utilization, and solid organic fertilizer can be transported to areas lacking fertilizer for use, which can improve soil structure.
Features:
1. Extrusion screw: double-wing blades, stainless steel, and specially processed to enhance anti-wear and anti-corrosion.
2. Filter screen: stainless steel material, precision machining; according to the type of customer materials, different specifications of screen gaps are used.
3. Discharge adjustment: According to the customer’s requirements for dry and wet solid materials after extrusion, the counterweights on both sides can be adjusted to achieve different dry and wet effects of extrusion and different output efficiency.
Principle:
The pig manure water is pumped into the pig manure solid-liquid separator by a submerged pump, and then dehydrated by the screw extrusion of the separator. The pig manure wastewater separated by extrusion filtration can be directly sent to the
biogas digester for fermentation of biogas or discharged to its wastewater sedimentation tank. Solid dry pig manure is extruded from the discharge port. After solid-liquid separation, COD and BOD in pig manure water are greatly reduced, which is convenient for subsequent discharge up to the standard. The separated pig manure water can be directly discharged to the biogas tank for biogas fermentation. The fermented pig manure residue liquid is a very good organic fertilizer liquid, and can also be discharged to the aeration tank for aeration and environmental protection treatment.
