The pig manure solid-liquid separator is an environmental-friendly equipment used in chicken farms for handling chicken manure, widely applied in the dehydration process of animal feces (chicken, duck, rabbit, pig, cow manure, etc.) in large and medium-sized animal husbandry farms. The working principle of the pig manure solid-liquid separator is as follows: Firstly, the chicken manure slurry is lifted and sent to the separator by the non-blocking submersible pump of the chicken manure processor. Then, the slurry is gradually pushed forward by a screw, while the pressure at the front edge of the machine is continuously increased. This forces the moisture in the material to be squeezed out through the screen under the action of the edge pressure, and drained out through the drainage pipe. The operation of the chicken manure solid-liquid separator is continuous. The chicken manure slurry is continuously lifted into the separator, and the pressure at the front edge keeps increasing. When it reaches a certain level, the discharge outlet is opened, and the material is extruded out, achieving the purpose of extrusion discharge.
