The heart machine is mainly used to separate solid particles from liquid in suspension, or to separate two liquids with different densities and immiscible in emulsion. It can also be used to remove liquid from wet solids, such as using a washing machine to spin Dry and wet clothes; special ultra-fast tube separators can also separate gas mixtures of different densities; taking advantage of the characteristics of solid particles of different densities or sizes having different settling speeds in liquids, some sedimentation can also separate solid particles according to density or particle size. Particle size classification.
A centrifuge is a machine that uses centrifugal force to accelerate the separation of different materials that need to be separated.
The main principle of the filter centrifuge is to accelerate the liquid phase in the solid-liquid mixture out of the drum through the centrifugal force generated by the high-speed centrifugal drum (coupled with appropriate filter materials), while leaving the solid phase in the drum. , to achieve the effect of separating solids and liquids, or commonly known as dehydration.
The main principle of the decanter centrifuge is to use the strong centrifugal force generated by the high-speed rotation of the rotor to accelerate the sedimentation speed of different specific gravity components (solid phase or liquid phase) in the mixed liquid, and separate substances with different sedimentation coefficients and buoyancy densities in the sample.
Centrifuges are widely used in mineral processing, coal preparation plants, coal washing plants, water treatment and shipbuilding and other departments.
When a suspension containing fine particles stands still, the suspended particles gradually sink due to the action of the gravity field. The heavier the particles, the faster they sink, whereas particles with a density less than the liquid will float. The speed at which particles move under a gravity field is related to the size, shape and density of the particles, and is also related to the strength of the gravity field and the viscosity of the liquid. Particles the size of red blood cells, several micrometers in diameter, can be observed settling under normal gravity.
In addition, diffusion occurs when substances settle in the medium. Diffusion is unconditional and absolute. Diffusion is inversely proportional to the mass of the substance. The smaller the particles, the more severe the diffusion. Subsidence is relative and conditional, and requires external force to move. Settlement is proportional to the weight of the object. The larger the particles, the faster they settle. For particles smaller than a few microns, such as viruses or proteins, they form a colloid or semi-colloidal state in solution, and it is impossible to observe the sedimentation process using gravity alone. Because the smaller the particles, the slower they settle and the more serious the diffusion phenomenon. Therefore, it is necessary to use a centrifuge to generate strong centrifugal force to force these particles to overcome diffusion and produce sedimentation motion.
Centrifugation uses the powerful centrifugal force generated by the high-speed rotation of the centrifuge rotor to accelerate the sedimentation rate of particles in the liquid and separate substances with different sedimentation coefficients and buoyancy densities in the sample.
★Advantages of AURY centrifuge
✬High centrifugal separation efficiency
Centrifuges use centrifugal force to separate liquid or solid particles. Because the centrifugal force can reach hundreds of times the acceleration of gravity, the centrifugal separation efficiency is very high, especially for the separation of small and micro particles.
✬Wide scope of application
The centrifuge has a very wide range of applications and can be used in medical, pharmaceutical, food, chemical, coal preparation, mineral processing, coal washing and other fields. It has a wide range of uses.
✬Simple operation
The operation of the Centrifuge Basket is very simple, as long as you operate it correctly according to the operating requirements. At the same time, the centrifuge also has a certain degree of automation, which can save labor costs and time.
✬Reliable
Because the centrifuge uses mechanical movement, its separation and processing effects are stable and reliable, it is not prone to failure, and it can reduce the operator’s direct contact with the material and is highly safe.
✬High convenience
Compared with other separation equipment, the centrifuge is relatively simple to operate and can achieve semi-automatic and fully automated control. At the same time, it can quickly complete the separation and processing of materials, improving production efficiency.
The centrifuge needs to be cleaned, maintained and maintained after use, otherwise the use effect and service life may be affected. And because the centrifuge rotates quickly, braking also takes a certain amount of time. Operators should pay attention to safety.
The centrifuge is a very common mechanical equipment with the advantages of high separation efficiency, wide application range, and simple operation. When choosing a centrifuge, you must consider the actual needs and equipment costs.
