Working Principle
Horizontal screw centrifuge is mainly based on the principle of “centrifugal sedimentation”. It generates strong centrifugal force through high-speed rotation, so that materials with different densities can be quickly separated, thereby achieving the purpose of solid-liquid or even solid-liquid-liquid separation.
The core structure includes:
Drum (shell): responsible for high-speed rotation to form a centrifugal field;
Screw conveyor: pushes the sediment to move to the slag discharge port at a differential speed;
Feeding system: maintains a stable inflow of materials to avoid impact;
Liquid discharge system: the clear liquid after separation is discharged through the overflow port;
Drive and control system: realize speed regulation, differential speed control, and automatic protection.
Separation process:
The mixed liquid enters the drum through the feed pipe;
Under the action of centrifugal force, the solid particles with high density are deposited on the drum wall;
The conveying screw slowly pushes the solid out of the equipment;
The clear liquid or light phase liquid is discharged from the central overflow port to form a continuous processing process.
This method realizes “continuous, automatic, and efficient” separation and is an indispensable separation core unit for modern industrial assembly lines.
Technical advantages
1. Automatic control, easy operation
Adopting PLC+touch screen control system, it supports real-time monitoring of multiple parameters (such as current, differential speed, torque, vibration, etc.), and can realize remote control, fault alarm, self-test and other functions, greatly reducing the difficulty and safety risks of manual operation.
2. Continuous operation, large processing capacity
The horizontal screw centrifuge can work continuously and stably for a long time, and the processing capacity of a single machine ranges from 1m³/h to more than 50m³/h. It is suitable for the continuous separation needs of large quantities of materials and improves the efficiency of the entire production line.
3. Energy saving and consumption reduction, green and environmental protection
Through the optimized energy consumption control module and variable frequency drive system, the energy consumption of the equipment is significantly lower than that of traditional treatment methods, and the use of reagents can be reduced, saving costs and being more environmentally friendly.
4. Wide range of materials
From low-concentration sludge to high-solid content oil sludge, from large-size particle mixtures to high-viscosity suspensions, the horizontal screw centrifuge can adapt to the treatment, showing excellent compatibility and stability.
5. Wear-resistant and corrosion-resistant, longer life
Key parts of the equipment are made of duplex stainless steel, ceramic alloy spraying or tungsten carbide wear-resistant sleeves, which extend the service life of the equipment, reduce maintenance frequency, and adapt to acid, alkali, and highly corrosive working conditions.
Deep integration of multi-industry application scenarios
Horizontal screw centrifuges have been widely used in the following industries:
1. Environmental protection industry
Applied to dehydration treatment of municipal sewage, printing and dyeing sewage, electroplating sewage, farm sludge, etc. The equipment is efficient, energy-saving, and easy to integrate with automatic dosing system.
2. Sludge treatment and energy recovery
Highly polluted materials such as oily sludge in oil fields and oil-water emulsions can be efficiently separated to achieve a win-win situation of resource reuse and environmental protection.
3. Food and dairy processing
Used for separation of fruit and vegetable residues, dehydration of soy sauce lees, processing of soy products, degreasing of milk, protein extraction, etc., to meet food-grade safety and cleanliness requirements.
4. Pharmaceuticals and bioengineering
Treat antibiotic fermentation broth, vaccine culture broth, bacterial separation, protein separation, etc. to ensure purity and batch consistency.
