Working principle of horizontal screw centrifuge
The core technology of horizontal screw centrifuge is based on the “centrifugal sedimentation principle”, and its working process mainly includes the following steps:
Feeding and distribution
The treated mixed liquid is continuously transported from the feed pipe to the inside of the equipment, and then transported to the inside of the drum through the feed screw. This process adopts a closed system to effectively reduce odor leakage and secondary pollution.
High-speed rotation forms a centrifugal field
After the equipment is started, the drum and the conveying screw rotate at a high speed with a certain differential speed, instantly forming a strong centrifugal force field in the drum cavity, so that components with different densities are quickly separated.
Solid-liquid separation is achieved
High-density solid particles settle on the inner wall of the drum, and are continuously pushed to the end of the cone by the spiral blades, and finally discharged from the slag discharge port; while low-density liquids are concentrated in the center and discharged from the overflow port at the other end, completing the continuous separation process.
Automatic adjustment and monitoring
High-end horizontal screw centrifuges are equipped with an intelligent PLC control system, which can realize real-time monitoring of differential speed, torque, vibration and temperature to ensure stable operation of the equipment under optimal working conditions.
Core advantages of decanter centrifuge
1. Continuous operation, higher efficiency
Compared with traditional intermittent separation equipment, decanter centrifuge can achieve 24-hour uninterrupted operation, greatly improving production efficiency, and is suitable for large flow and high concentration material processing needs.
2. Self-cleaning, self-slag discharge, convenient maintenance
The equipment is designed with an automatic slag discharge system to avoid frequent shutdowns for cleaning, reduce labor costs and equipment wear, and is suitable for high-frequency operation scenarios.
3. Strong adaptability and wide material compatibility
Whether it is a suspension with high solid content, high viscosity, and fine particle size, or a complex mixture containing oil and fiber, the decanter centrifuge can stably separate and has strong adaptability.
4. Energy saving and environmental protection, helping green development
Modern decanter centrifuges use variable frequency speed regulation and intelligent control systems to reduce energy consumption while ensuring separation efficiency, in line with global environmental protection trends.
Industry Applications
1. Sewage Treatment Industry
In municipal sewage, industrial wastewater, aquaculture sewage and other projects, the horizontal screw centrifuge can efficiently remove moisture from the sludge, reduce the volume of sludge, and facilitate subsequent incineration or landfill. It is an indispensable core equipment in the environmental protection industry.
2. Food Processing Industry
It is used to separate materials such as soybean milk residue, fruit and vegetable pulp residue, starch, soy sauce and distiller’s grains to ensure product purity, taste consistency and production line cleanliness.
3. Biomedicine and Fermentation Industry
In the fields of antibiotics, vaccines, bacterial proteins, etc., the horizontal screw centrifuge can achieve efficient bacterial recovery and clear liquid extraction to improve product quality.
4. Chemical and Sludge Treatment
Faced with highly viscous and highly corrosive chemical residues or sludge waste, the equipment is made of duplex alloy or wear-resistant and corrosion-resistant materials to ensure long life and stable operation.
Procurement Recommendations
How to choose a suitable decanter centrifuge?
When selecting a centrifuge, it is recommended to pay attention to the following key parameters:
Processing capacity (m³/h): determines the throughput of the equipment and needs to match the actual production line load;
Differential speed adjustment range: affects the separation accuracy and slag discharge speed;
Drum length-to-diameter ratio (L/D): The larger the L/D, the better the clarification performance;
Material and corrosion resistance level: Different materials have different requirements for equipment materials;
Whether it has an online cleaning system (CIP) and explosion-proof function: It is particularly critical for industries such as food, medicine, and chemicals.
As modern industry increasingly pursues high quality, low energy consumption and intelligence, the decanter centrifuge is not only a tool to solve separation problems, but also an important “promoter” of industrial upgrading and transformation.
