Working principle of spiral extrusion solid-liquid separator

The working principle of the spiral extrusion solid-liquid separator is mainly based on the principle of spiral extrusion, which effectively separates solids and liquids through physical methods, achieving the goal of reducing solid waste and purifying liquids. The detailed working principle is as follows:

Components of the separator

• Spiral shaft: responsible for rotating under the drive of the driving device, pushing and squeezing materials.
• Squeezing chamber: It is the main place for separating solid-liquid mixtures.
• Feed inlet: used to introduce the solid-liquid mixture to be processed into the extrusion chamber.
• Discharge outlet: Solid material is discharged after being squeezed.
• Screen: intercepts solid substances and allows liquids to pass through.
• Drive device: Provides power to drive the spiral shaft to rotate.
• In addition, it may also include other auxiliary components such as unobstructed pumps, control cabinets, pipelines, etc., and the specific configuration may vary depending on the model and application scenario.

The working process of the separator

• Feed: The solid-liquid mixture to be processed enters the extrusion chamber through the feed inlet.
• Squeeze separation: Under the propulsion and squeezing action of the spiral shaft, solid particles are gradually compressed and move forward. At the same time, the stirring and squeezing of the spiral shaft and spiral blades intercept the solid material by the sieve, while the liquid flows out through the gaps of the sieve, achieving solid-liquid separation.
• Discharge: With the continuous rotation of the spiral shaft, the compressed solid material is pushed towards the discharge port and finally discharged from the equipment.

Application scenarios of separators

• Sewage treatment: Used for sludge treatment in sewage treatment plants, it can effectively squeeze out the water in the sludge, reduce the volume of the sludge, and facilitate subsequent treatment.
• Food processing: Used in the food processing process to treat solid waste liquids and recover valuable substances.
• Pharmaceutical and chemical industries: In chemical production, solid waste liquids are treated to reduce environmental pollution.
• Livestock farming: Processing livestock manure and wastewater, separating solid and liquid organic fertilizers for subsequent utilization.

Advantages of Separators

• Simple structure: The device has a compact structure and occupies a small area.
• Easy to operate: high degree of automation, easy to operate, and easy to maintain.
• Strong processing ability: With a large daily processing volume, it is suitable for continuous operations.
• High durability: Key components are made of corrosion-resistant and high-strength materials, with a long service life.

In summary, the spiral extrusion solid-liquid separator has demonstrated excellent performance and broad application prospects in multiple fields through its unique working principle and structural design.
