Stacked screw sludge solid-liquid separator

Stacked screw sludge solid-liquid separator

Introduction

The stacked screw solid-liquid separator is an efficient and environmentally friendly equipment that combines innovative design and technology, specially developed for the separation of various liquids containing solid particles. It stands out among the solid-liquid separation processes in many industries due to its performance, helping enterprises achieve the dual goals of resource recycling and environmental protection standards. The device adopts a compact modular design, with a delicate structure and easy installation, and can be widely used in various production scenarios and processing projects of different scales.

working principle

Stacked screw sludge solid-liquid separatorThe core working principle is based on the synergistic effect of spiral extrusion and laminated filtration. The device body is composed of a spiral shaft and multiple layers of laminations, which are divided into fixed laminations and movable laminations. When the mixed liquid to be processed enters the equipment, the spiral shaft begins to rotate, pushing the mixed liquid to move along the axial direction. During the movement, the mixed liquid passes through the gaps between the stacked pieces. As the wedge-shaped space formed by the fixed stacked pieces and the moving stacked pieces gradually narrows, the squeezing force on the mixed liquid gradually increases. At this point, the liquid flows out through the gaps in the stack under pressure, while the solid particles are trapped inside the stack. With the continuous advancement of the spiral shaft, the solid particles are constantly squeezed, eventually forming a filter cake with high dryness and being discharged from the discharge port, achieving precise solid-liquid separation.

Product advantages

Efficient separation and large processing capacity: The unique design of laminations and spiral shafts greatly increases the filtration area and extrusion effect, greatly improving the efficiency of solid-liquid separation. It can process a large amount of mixed liquids per hour, which can meet the production needs of enterprises of different scales and save processing time and costs for enterprises.

Self cleaning, long-lasting stability: During operation, the spiral shaft drives the moving laminations to move axially, causing relative displacement between the laminations and achieving automatic cleaning function. This effectively prevents solid particles from blocking the gaps between the stacked sheets, ensuring long-term stable operation of the equipment, reducing downtime and maintenance caused by blockage, and improving equipment efficiency.

Strong adaptability and wide application: Whether it is high concentration or low concentration mixed liquids, whether it contains small particles or fibrous substances, the stacked screw solid-liquid separator can effectively process them. It exhibits good adaptability to materials of different industries and properties, and can meet diverse solid-liquid separation needs.

Low energy consumption and green energy saving: Compared with traditional solid-liquid separation equipment, the stacked screw solid-liquid separator does not require complex high-pressure systems and large power devices. It relies on the clever combination of the rotation of the spiral shaft and the stacking of sheets to achieve separation, significantly reducing energy consumption and in line with the development concept of green energy saving in modern enterprises, reducing operating costs.

Compact structure, space saving: The overall structure is compact, occupies a small area, and is easy to install and layout. Especially suitable for enterprises or projects with limited space, it can be flexibly placed in various production workshops or processing sites, effectively saving space resources.
