Analysis of the technical principle of tubular centrifuge
Tubular centrifuge is a high-speed, high-separation factor centrifugal separation equipment, which is widely used in the separation operation of complex material systems such as liquid-liquid, liquid-solid, solid-liquid-liquid, etc. Its basic working principle is:
High-speed rotation forms a strong centrifugal force field
The tubular centrifuge drives the drum to rotate at high speed through the motor, the speed can reach 15000~20000r/min, and the maximum centrifugal force can reach more than 15000g. After the material enters the drum, under the action of centrifugal force, materials with different densities are quickly separated according to the density gradient.
Liquid phase and solid phase are deposited in different radius areas
High-density solid or impurity particles are thrown to the inner wall of the drum to form sediment; low-density liquid forms clear liquid in the inner layer and is discharged from the upper outlet; if it is an emulsion, the light and heavy phases will also be discharged in layers.
Continuous feeding and intermittent slag discharge
Tubular centrifuges usually use continuous feeding to ensure efficient and stable separation process, while solid impurities need to be removed manually or mechanically through regular shutdown. They are suitable for processing materials with low solid content but high precision requirements.
Equipment structure design: the precise system behind the high speed
Although the tubular centrifuge has a compact appearance, its internal structure is very precise. Its main components include:
Spindle system: connected to the high-speed motor, the transmission is stable, and the dynamic balancing system is used to ensure that the drum is vibration-free at high speed.
Drum assembly: one of the key components, made of high-quality stainless steel or special alloy, corrosion-resistant and wear-resistant, with a smooth inner wall to reduce sediment accumulation.
Base and support structure: usually cast iron or thick plate steel structure, equipped with a shock absorption system to ensure the stability of equipment operation.
Bearing and sealing system: high-speed wear-resistant bearings and multi-channel sealing systems are selected to extend the service life and prevent material leakage.
Core advantages: Why do we recommend tubular centrifuges?
1. High separation accuracy
The biggest feature of tubular centrifuges is their strong precision separation capability. They are particularly suitable for separating ultrafine particles or emulsions with a particle size below 1μm. The traditional sedimentation method is difficult to achieve, but tubular centrifuges can easily do the job.
2. Small footprint
The equipment has a compact structure and occupies only 1/5 of the floor space of an ordinary horizontal screw centrifuge. It is especially suitable for use in laboratories with limited space, small batch production workshops or pharmaceutical clean areas.
3. Low noise and low energy consumption
The noise of the whole machine is controlled below 70dB, the operation is stable, and the power consumption is low. It is more energy-saving and environmentally friendly than other centrifugal equipment with the same production capacity.
4. Strong customization
We can customize the drum material, speed range, control system (such as PLC automation), liquid discharge structure and other solutions according to the viscosity, corrosiveness and output requirements of different industries.
5. Low maintenance cost
Except for regular manual slag discharge, the whole machine requires almost no complex maintenance. We provide one-year warranty and lifetime technical support for key components.
Wide range of applications: one machine for multiple uses, value doubled
Food and plant extraction industry
Such as tea polyphenols, anthocyanins, natural pigments, oils, protein extraction, etc. While maintaining the integrity of active substances, high-purity separation is achieved.
Biopharmaceutical field
Vaccines, antibiotics, microbial fermentation broth, blood products, enzyme preparations, etc. require extremely high sterile environment and ultra-high precision.
Chemical and fine chemicals
Catalyst recovery, metal salt solution purification, emulsion separation, nanomaterial processing, etc. require separation efficiency and production capacity.
Environmental water treatment and waste liquid separation
Laboratory waste liquid, emulsified cutting fluid, precision electronic cleaning wastewater, etc., can achieve effective concentration and recycling of pollutants.
As the separation precision requirement is increasing, tubular centrifuge, as an efficient, reliable and easy-to-maintain separation equipment, is bringing innovation and value to more industries. As China’s leading tubular centrifuge manufacturer, we are willing to work with global customers to create an efficient and clean production future with our professional technical accumulation, rich application experience and perfect service system.
