I. Overview Decanter Centrifuge is the use of centrifugal sedimentation principle the suspension complete solid-liquid separation equipment. Decanter Centrifuge use solid-liquid suspensions difference in specific gravity, resulting in a strong centrifugal force field after the operation, the solid phase is settling under the influence of centrifugal force, in order to achieve solid-liquid separation. The principle is that when the inner materials into high-speed rotation of the centrifuge drum, due to the centrifugal force by the sample sizes, the suspension of large particles was severely affected by the centrifugal force and is sinking to the drum wall and the drum in the same direction However, rotation of the inner rotor slip spiral vane presence of the pusher to push out the liquid discharge port, in order to achieve various degrees of solid-liquid separation process. Second, the structural characteristics and uses: Decanter centrifuge is mainly used to have a fixed proportion of poor solid-liquid phase suspension phase dehydration, liquid clarification, grading, concentration and other processes. The company produces Decanter centrifuges large capacity, small footprint, continuous operation and low operating costs. With high efficiency, high dry. Energy saving advantages. Its materials adaptable, by changing the helix within various structures, and technical specifications can be difficult to adapt to separation of smaller particles, such as the separation of materials. Outer drum barrel auger three rotor conditions within the Company's production of Decanter centrifuges auger, according to the structural separation requirements in different materials, divided into various forms, has its unique of place. Outer drum with large aspect ratio structures, which can meet the separation, but also to achieve the purpose of processing a large amount of 0.3 to 30% solids particle size 0.005 ~ 5mm, the temperature at 0 ℃ ~ 100 ℃, the solid-liquid gravity concentration separating suspensions difference ≥0.05g / cm3 can be selected for this series of centrifuges. Centrifuge technical indicators to achieve: Solid Recovery: ~ 99%; the cake moisture content :( municipal sludge) ≤75%; Noise:. ≤85dB (A) ceramic sets, sets carbide alloy block and outside the drum wear parts by inlaid carbide ceramic sleeve or sleeve, wear-resistant alloy welding block, increase wear resistance, increase service life. Technical features: △: stand-alone processing capacity, smooth operation, low energy saving footprint. △: involute planetary gear differential, transmission ratio, high precision. △: main bearings are imported bearings, high reliability and long operational life. △: machine with a variety of safety overload protection devices to ensure safety and reliability. △: the machine has a common type and explosion-proof electrical control system to adapt to different conditions occasions. △: Ministry of contact with the materials are made of high quality stainless steel, the important parts are forged. △: inside and outside of the drum cone angle and a large multi-aspect ratio structures, ensuring large capacity, the material to dry. △: Java port and screw pusher surface using carbide hardfacing materials for processing, wear resistance. △: structure and overall chassis are strictly deal to do to eliminate stress, high reliability without distortion. △: stent may need to design a low center of gravity type, high scaffolding, mobile user workplace. △: dual-rotor balancing strict accordance with national standards, testing and balancing work hard to support balancing test. △: according to actual needs can be equipped with single frequency, dual frequency, and PLC intelligent automatic electric control system. Note: The above is the overall technical characteristics, specific parameters can be separated according to material characteristics of the user's discretion, and depending on use conditions.
