Technology
A decanter centrifuge is made up of a rotating bowl with a separate revolving scroll inside. The dewatering solids and liquid (sludge/slurry) are fed by an inlet pipe into a mixing chamber in the scroll where polymer is provided to achieve flocculation and improve dewatering performance. The slurry is flung against the bowl's outer sides and conveyed out of the decanter via the scroll, while the centrate water is pressed back to the centrate exit. The water level in the bowl is controlled, and the composition of the slurry dictates the appropriate water level. Depending on the model and type of slurry, the drum and scroll can rotate separately at speeds of up to 3600 RPM.
Principle of operation:
Separation is used to separate compounds with varying mass ratios from a mixed solution.Solid-liquid separation, liquid-liquid separation, and liquid-liquid-solid separation were all types of separation.
When mixed fluid enters the centrifuge's revolving bowl via the feed tube, solids with higher density rapidly deposit on the inner wall of the bowl due to centrifugal acceleration.The spiral pusher then pushes the deposited solids to the taper end of the bowl and discharges them from the centrifuge through the residual exit.Meanwhile, the liquid phase with lower density forms a liquid ring layer and discharges from the bowl through the overflow port, the bowl and spiral pusher run at high speeds simultaneously, and deposited solids on the bowl's wall could be conveyed to the residue outlet by the spiral pusher due to the speed discrepancy.This separation procedure is repeated indefinitely.
Separation method
Gravitational separation-liquid discharge-sediment discharge-feeding.
Factors influencing separation The centrifuging factor, the length to diameter ratio of the cavity, and the depth of the fluid pool.
Field command
The rotational speed difference between the spiral pusher and the bowl depth of the liquid pool.
The shredded fish fillets will go through two to three cleaning steps in the manufacturing of surimi. Impurities such as blood and fat are flushed out during this procedure. Typically, washing water is filtered using a spinning sieve.
A screw press is used to dehydrate fish meat in traditional surimi manufacture. The beef is subsequently antifreeze-treated and deep-frozen. This method of producing surimi has numerous drawbacks:
Different washing steps and the screw pressing technique result in significant fish fiber loss.
1.A large amount of cleaning water is required.
2.Extremely large space need
3.The raw material is susceptible to bacterial contamination.
All of the problems listed above can be solved by the Shenzhou decanter centrifuge. The decanter centrifuge can not only recover fish meat from washing water, but it can also replace the screw press in the manufacture of surimi. The output rate of the surimi production process can thus be greatly increased.

Basic technological characteristics
1. Industrial layout
The overall machine set design adheres to the principle of advanced industrial design, ensuring the machine's stability, functionality, and safety.During operation, it also effectively absorbs shear force from dynamic load.
2. Effectively reduce resonance during bi-rotor rotation
When the centrifuge is in operation, there are no evident first-order and second-order resonance zones within the prescribed speed range, while the entire vibration intensity of the bearing seat is defined as 2mm/s-4mm/s.All of this reduces fatigue damage to components and assembly units caused by high frequency vibration during operation and rapid vibration when shutting down.
3. Completely remove the phenomena of liquid ring stalling.
The phenomenon of liquid ring stalling occurs during the heavy workload boot or shutdown operation of a complete set machine, particularly for LW550 and bigger models. It generates bounce or wild shake, causing extra impact fatigue damage to main bearings, screw bearings, and the inner sections of the rotary bowl.Fortunately, our engineers properly solved this problem.
4. Use of a novel technique in the major component work-blanks
The major component work-blanks are manufactured using centrifugal casting technology and overall mould-making forging technique, which completely avoids dangers such as inter-granular corrosion and relaxation of residual stress release in welding joint.
5. Selection of main bearings
We employ bearings from international first-line companies such as SKF, FAG, and others.
6. Detection of constant temperature
To ensure that actual processing quality fulfills the criteria of specified precision accuracy, all fashioning components and assembly units are detected in constant temperature conditions.
7. The ability to interchange
The physical design of the entire machine, as well as the processing technology used in important positions, ensure that all assembly units and bowls of the same centrifuge type are interchangeable.It not only makes equipment easier to maintain, but it also improves its reliability and safety.
8. Bearing disassembly is simple and safe.
During the disassembly of the bearing from the machine, one layer of oil film is injected into the contact surfaces between the bearing and the work-piece using high pressure.This would essentially minimize friction between separate sections.As a result, when disassembling the bearing, it would save 90% of the pulling force and limit the danger of damage to high-precision parts.
9.The primary bearing lubrication system
For specific product models, there are two types of lubrication systems:
A light oil lubrication

Oil pump provides continuous power to ensure oil works in a circular fashion
Jet oil lubrication constantly cleans and lubricates bearings while lowering temperature
Oil filter system ensures lubricant cleanliness
Oil pressure energy storage system ensures lubrication pump provides an extra oil supply (pressure no less than 0.4Mpa) for 5-6 minutes when power fails accidentally
Constant temperature system is available.

B grease lubrication

Use a grease with extreme pressure resistance, oxidation resistance, abrasion resistance, water scour resistance, corrosion resistance, and high temperature resistance. The optional automatic grease system replenishes grease on the main bearing at predetermined hours and quantities.
10. BH device for main bearing (patent design)
At either end of the main bearing, there are two spare safe bearings.When a machine operates properly, it maintains a particular clearance from the bearing inside track to the main axis.When an unforeseen condition happens, the main bearing is damaged, or the circle center deviation causes an amplitude of vibration to reach the required clearance, the safe bearings take over as the main bearing. Meanwhile, if the computer automatic control system detects an abnormal vibration value on a bearing position, it promptly triggers an emergency shutdown and performs a smooth shutdown.This technology guards against machine damage and ensures production safety.
11. GSRL feeding apparatus (powerful design)
The new internal spiral core tube design has achieved the following results.Shorten triangular belt traction time, eliminate swirling flow disorder, and extend separation time without reducing centrifugal acceleration.Meanwhile, the centrifuge's inner working pressure rises and liquid foaming is reduced.
