Filter centrifuge, using filter cloth or filter screen, has the characteristics of high production capacity, low and uniform power consumption, no peak load, compact structure, fast drying, good corrosion resistance, etc.

Filter centrifuge； A centrifugal separator that separates components in a suspension by centrifugal filtration. There are many holes on the wall of the filter centrifuge drum, and the inner surface of the drum is covered with filter media. The suspension added to the drum rotates with the drum to generate huge centrifugal pressure. Under the action of pressure, the liquid in the suspension flows through the filter medium and the holes on the drum wall and is thrown out. The solid is trapped on the surface of the filter medium, thereby achieving the separation of solid and liquid. The centrifugal force generated by the suspension in the drum is hundreds of times that of gravity, which strengthens the filtration process, speeds up the filtration speed, and obtains filter residue with lower moisture content. Suspensions with solid particles larger than 0.01 mm can generally be filtered with a filter centrifuge. For suspensions containing particles larger than 0.01 mm, a filter centrifuge can be used

Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two liquids with different densities that are immiscible in emulsions (such as separating cream from milk).； It can also be used to remove liquid from wet solids, such as spinning wet clothes in a washing machine ； Special ultra-fast tube separators can also separate gas mixtures of different densities ； Taking advantage of the different sedimentation speeds of solid particles of different densities or sizes in liquids, some sedimentation centrifuges can also classify solid particles according to density or size.

Flat-type upper discharge clean sling centrifuge ●Structure: The shell is equipped with a flip cover, feed pipe, washing pipe, observation mirror, exhaust port, and lighting hole. ； Sealed structure, drum, shell, flip cover and other parts are made of stainless steel or lined with plastic. ●All fasteners are stainless steel. ●Transmission and braking: Ordinary motor (or explosion-proof motor) + frequency converter + energy consumption braking + control box. ●Liquid damping shock absorber. ●The machine is equipped with a set of special spreaders when it leaves the factory. ●This machine adopts the hanging bag unloading method, which has low labor intensity and high work efficiency. ●Adopting variable frequency control, it starts smoothly and the speed is adjustable. ●The structural parts have smooth transitions, the surfaces are polished, and all exposed parts and fasteners are made of stainless steel. The casing is a large flip-up cover, which can thoroughly clean the space between the centrifuge casing and the drum. Effectively eliminate cross-contamination between batches. ●The machine base is a flat-plate structure, which lowers the center of gravity of the machine and results in a small installation space. The flat-panel base can also be used as an operating platform, making it more convenient to operate. A liquid damping shock absorber is installed between the flat-panel base and the ground, so there is no vibration interference to the basic floor and peripheral equipment. ●The humanized design of the large flip cover is connected to the simplified body with two sets of balancing cylinders, making it easy to open the cover. The flip cover is equipped with a feed pipe, a washing pipe, a sight glass hole, an explosion-proof light, and a nitrogen flushing pipe. ●An online cleaning system is installed to clean the inner wall of the centrifuge shell, the inner and outer surfaces of the drum and the invisible parts inside the centrifuge, ensuring cleanliness and complying with GMP specifications. ●Not easy to break crystals. ●Sealed structure, the sealing strip is made of silicone rubber or fluorine rubber, which can meet the requirements of sealing and explosion-proof, and is suitable for applications in toxic, flammable and explosive situations.

The flat-bed bag centrifuge is a high-performance filter centrifuge for bag discharging and intermittent operation. It is suitable for solid-liquid separation in suspensions with high solid phase looseness, moderate particle size, difficulty in compression, need for washing, and small liquid phase viscosity. It is especially suitable for solid-liquid separation where materials are not suitable for human contact, require high cleanliness, and have strict washing requirements. Widely used in pharmaceutical, food, health care, national defense, light industry and other industries.

The hanging bag centrifuge is a new type of centrifuge designed and manufactured in conjunction with the calcium carbonate industry. Its drive motor is controlled by a variable frequency speed regulation system and starts smoothly. The power is transmitted to the drum through the V-belt, driving the drum to rotate the drum's own axis at high speed, forming a centrifugal force field, and the materials to be separated are passed through The upper feeding pipe enters the high-speed rotating drum. Under the action of the centrifuge force field, the material is evenly distributed on the wall of the drum for centrifugation. The liquid phase passes through the gap between the solid material and the filter bag, is thrown to the cavity of the casing through the hole of the drum, and is discharged from the liquid outlet of the chassis. The solid material is trapped in the filter bag. After the machine is stopped, open the machine cover (with the help of a specially designed balance assist device), pull out the locking bolt of the orchid cover, and use a special spreader to lift the filter cake out of the machine to a set location for discharge, thus completing a working cycle. The machine cover is equipped with a washing pipe to wash materials.
