The structure is relatively simple, mainly composed of inclined screen mesh and driving device.
Screens are usually made of stainless steel or other corrosion-resistant materials, which can effectively remove solid impurities from liquids.
It also includes a sieve tray to support the sieve, making it easier for the sieve to self clean.
Stacked screw solid-liquid separator (also known as a type of spiral solid-liquid separator):
The structure is relatively complex, consisting of multiple spiral blades stacked together to form multiple spiral channels.
The core component is the screw conveyor, which performs solid-liquid separation through rotational motion.
Usually, it also includes parts such as feed inlet, liquid outlet, and slag discharge outlet.
Working principle
Slant screen solid-liquid separator:
By utilizing the filtering function of the sieve, solid substances are blocked on the sieve, while liquids enter the underscreen pump through the sieve, achieving solid-liquid separation.
The spiral auger extracts the dirt from the sieve and cleans it thoroughly through an automatic backwash system.
Stacked screw solid-liquid separator:
By rotating the spiral blades, solid particles in the solid-liquid mixture are separated.
Solid particles move upward under the drive of spiral blades, while liquid flows out through the gaps between the blades, achieving solid-liquid separation.
Separation effect and applicable scenarios
Slant screen solid-liquid separator:
Usually suitable for handling liquids containing small amounts of solid impurities.
The separation effect mainly depends on the pore size and inclination angle of the sieve.
Mainly used for liquid filtration in industries such as chemical, food, and pharmaceutical.
Stacked screw solid-liquid separator:
Suitable for handling liquids containing a large amount of solid impurities or fibers.
The separation effect is influenced by the design of the spiral blades, rotation speed, and mixture characteristics.
Mainly used in scenarios such as sewage treatment and sludge dewatering.
operation and maintenance
Slant screen solid-liquid separator:
Easy to operate, simply pour the liquid to be processed into the machine and start the driving device to complete the separation.
Easy maintenance and low cost of screen replacement.
Stacked screw solid-liquid separator:
The operation is relatively complex and requires corresponding adjustments based on the characteristics of the mixture to be processed.
The maintenance cost may be high, but it has a high degree of automation and can operate continuously.
