How does the organic fertilizer solid-liquid separator work

Organic fertilizer solid-liquid separator is mainly used to treat high concentration organic wastewater such as poultry manure, pulp, distiller’s grains, and slaughterhouse waste. Through solid-liquid separation, it is converted into liquid organic fertilizer and solid organic fertilizer. The following is a detailed explanation of its working principle:

Working principle

Organic fertilizer solid-liquid separators, especially spiral extrusion solid-liquid separators, are mainly composed of equipment such as a main engine, unobstructed pumps, control cabinets, pipelines, mesh screens, reduction motors, and discharge devices. The working process is roughly as follows:

• Pump feeding: The unobstructed submersible pump pumps raw manure into the machine body. Accelerate the feed under the action of the pump to prepare for the subsequent solid-liquid separation.
• Spiral squeezing: Through power transmission, the squeezing screw (spiral propeller) gradually pushes the fecal water towards the front of the body. During this process, the moisture in the material is squeezed out of the mesh screen by the edge pressure belt filter and flows out of the drainage pipe.
• Continuous separation: The operation of the solid-liquid separator is continuous, and the material is continuously pumped into the body, resulting in an increasing pressure at the leading edge. When the pressure increases to a certain extent, the discharge port will be pushed open, and the extrusion port will be squeezed out to achieve the purpose of extrusion discharge.
• Adjustment of discharge: In order to control the speed and moisture content of the discharge, the counterweight block below the host can be adjusted to achieve a satisfactory discharge state.

Equipment features

• High level of automation: Organic fertilizer solid-liquid separators usually have a high level of automation, simple operation, and easy maintenance.
• Large processing capacity: With a large daily processing capacity, it is suitable for the solid-liquid separation needs of large-scale aquaculture farms.
• Low power consumption: using pure copper generator and stainless steel filter screen, corrosion-resistant, wear-resistant, long service life, low power and high efficiency.
• Small footprint: The spiral extrusion solid-liquid separator is divided into carbon steel and stainless steel models, with low purchase cost and small footprint.

Application scenarios

Organic fertilizer solid-liquid separators are widely used in various breeding farms, such as cattle farms, pig farms, chicken farms, etc. They are also suitable for the treatment of high concentration organic wastewater such as pulp, distiller’s grains, and slaughterhouse waste.

Separate products

• Liquid organic fertilizer: The liquid portion processed by a solid-liquid separator contains abundant nutrients and can be directly used for agricultural irrigation or as liquid fertilizer.
• Solid organic fertilizer: The separated solid portion, after further processing, can be used as fish feed or sold directly, improving economic benefits.

Overall, the organic fertilizer solid-liquid separator achieves solid-liquid separation of high concentration organic wastewater through mechanical actions such as spiral extrusion, providing important technical support for the production of organic fertilizers.
