Product Description
Shenzhou Explosion-Proof Type Decanter Centrifuge Machine used in Pharmaceutical plant extraction
LWS decanter separator is suitable for plant oil,( such as palm oil, coconut oil, olive oil separation ,) animal oil(such as fish oil, restaurant garbage ect) coal tar dehydration and slag,adapted to the different viscosity and water content in coal tar separation (emulsion), after separating the tar reach national standard.
Operating principle:
3phase liquid-liquid-solid Decanter centrifuges, also called tricanter , Taking advantage of the principle that the heavy
liquid,light liquid and solid phase, with different density and mutually insoluble in the mixed liquid, gain different
sedimentation speed in the centrifugal force field or gravity force field, separating stratification or causing the solid
particles in the liquid to deposit can be achieved.It is the popular machine throughout the world and widely used in the crude oil separation.Specially used for remove sludge and water from crude oil.

★ Special spiral structure
The DDGS high efficiency centrifuge fully draws on the working principle of the lamella settler. To improve the clarity of the
supernatant after centrifuge separation, a certain number of solid particles capturing plates (referred to as spiral plates) are added to the screw conveyor at the clarification section. When the solid suspended particles flow through the spiral ramp, part of them can be effectively attached to the spiral ramp and slide along it into the blades of the screw conveyor to realize continuous slag discharging. Compared with common centrifuges, it can increase 20~30% in solid recovery rate.★ High performance wear-and corrosion-resistant cemented carbide
The DDGS slurry produced with different raw materials through different processes has different degrees of corrosiveness, such as hydrochloric acid or sulfuric acid used at the acid chemical section, amino acid or acetic acid produced by fermentation. Therefore, the centrifuge has some requirements on the selection of wear-resistant materials.
★ High-dryness screw conveyor and drum structure
The dehydration of solid particles relies mainly on strong centrifugal force, high-torque spin extrusion force (pushing torque), and ultra-long solid particle dehydration length. The centrifuge can generate centrifugal force exceeding 3000G, 30 ~ 50% higher than the screw pushing torque of common centrifuges. The screw pusher torque, and the drum dehydration length is 10 ~ 20% longer than that of common centrifuges.
★ High torque involute planetary gear differential
The ultra-high pushing torque requires a high-torque involute planetary gear differential as the foundation. The differential
equipped on the centrifuge features high torque, high speed, low heat generation, and excellent heat dispersion, which ensure that the centrifuge can be used for a long time and stably.

Detail
Scroll
The scroll of the REYES decanter centrifuge is the most flexible scroll available on the market. Its specific open flight design reduces the torque created by the sludge and maximizes the clarification rate. The special cone design leads to high sludge compaction. • Reduction of sludge conveying torque by 30%, which impacts the gear box lifetime and the scroll drive size positively. • High cake dryness due to better solid compaction. • Excellent centrate quality due to minimized internal turbulences and maximized settling volume!
Bowl:
The bowl design is carefully selected to balance the various needs for integrity, stability, smooth operation, minimized windage, high durability, low wear, and easy maintenance, while ensuring the principle process functions. The design is modular to allow an easy fit to different basic process conditions by adjustment of diameter, length, and cone angle. The overall design is optimized to minimize the power consumption and provide the best possible stiffness. REYES decanter centrifuges are not only factory-tested before delivery to a customer's site, but also extensively type-tested according to international standards to meet all product safety requirements
MACHINE CONTROL AND PROTECTION
REYES decanter centrifuges will be as transparent in operation and for maintenance as you require. From the minimum machine protection to all levels of predictive maintenance information, including bearing conditioning sensors, the ecommended minimum configuration depends on your operation and your application environment. It can be scaled to your needs in perfect combination with our add control systems to support optimization of your operation. Our separation specialists seek to make operation and good care of your equipment, ensuring a long service life, blend seamlessly into your work schedule, and will provide fast and precise support should you need it.

II. Technical characteristics of the high-efficiency centrifuge for glutamic acid
★ Special spiral structure
The high-efficiency centrifuge for glutamic acid fully considers the number of solids in the high-concentration glutamic acid slurry, and fully adopts the variable pitch technology in the structural design process, exerting the slag conveying performance of the spiral blade to the maximum extent without causing the lifting angle of the spiral blade to disturb the solid particles and effectively improving the processing capacity of the centrifuge.
★ High performance wear-and corrosion-resistant cemented carbide
The thickness of the massive solid residues produced from high-concentration glutamic acid slurry in the drum is more than double of that in the conventional industry, so that it is necessary to adopt a higher level of wear-resistant technology.
★ Humanized process design
After the first separation of glutamic acid, it is necessary to consider diluting it with water to carry out the second separation process. The high-efficiency centrifuge for glutamic acid is equipped with a dilution water nozzle at the slag outlet of first separation.
★ High torque involute planetary gear differential
The ultra-high pushing torque produced from massive solid residues in the conveying process requires a high-torque involute planetary gear differential as the foundation. The differential equipped on the centrifuge features high torque, high speed, low heat generation, and excellent heat dispersion, which ensure that the centrifuge can be used for a long time and stably.
★ CIP washing system
The fully automatic control system is equipped with a CIP washing system, which can effectively solve the problem that it is not completely cleaned during the shutdown process and effectively avoid the equipment troubles caused by artificial factors.

Decanter Centrifuges Limitations:
* The decanter centrifuges cannot separate biological solids with very small density differences, such as cells and viruses. A competitive process that is capable of separating these difficult-to-separate solids is the tubular-bowl centrifuge.
* The machine can be very noisy and can cause vibration.
* The device has a high-energy consumption due to high G-forces.
* The decanter centrifuge has high equipment capital costs. Hard surfacing and abrasion protection materials are required for the scroll to reduce wear and therefore reduce the maintenance of the scroll wear.
