Decanter Centrifuge for Cleaning Wash Water in Pet Bottle Recycling

Product Description

Product Description DECANTER CENTRIFUGE FOR CLEANING WASH WATER IN PET BOTTLE RECYCLING
Shenzhou centrifuge:the mechanical engineering company and supplier of plants and systems, makes an ecologically and economically valuable contribution to the recycling of PET bottles.
SHENZHOU centrifuge supports its customers with centrifuge technology, the shenzhou sludge Decanter pro line. These decanter centrifuges remove contaminants from the wastewater originating out of washing and caustic water circuit in the recycling process. Numerous decanters have already been delivered and installed by plant manufacturers to turnkey PET recycling plants all over the world - including Mexico, North America, Saudi Arabia, Thailand, Japan, New Zealand, Great Britain, Romania, Poland, Portugal, Austria, Germany and the Netherlands.
The requirement of shenzhou decanters will continue to rise as the usage of PET containers around the world is increasing and growing. This and the simultaneously increasing trend towards reuse are leading to a large amount of washing water being produced in the recycling process. This is where the Shenzhou decanters become a valuable asset.
How shenzhou technology works for the environment PET containers are made of polyethylene terephthalate (PET). This is a thermoplastic produced by polycondensation and belongs to the polyester family. One of the raw materials used in its production is petroleum. But how are used PET bottles turned into rain jackets, sports shoes, running shirts, fibers, for example as fleece for functional clothing or cushion filling, filing baskets, binders or the processing of the polyester in hygiene products such as wet wipes, bed fillings, reusable bags, car boot linings, sports and functional garments, right through to "bottle-to-bottle" recycling, which requires very tedious process of cleaning of used PET bottles?
In the recycling process, old PET products are first shredded into small pieces of two to three millimeters. Then hot and cold washing and subsequently caustic water is carried out to remove dirt such as sand, solids, sticker and adhesive residues.
In order that washing water and expensive alkaline solutions do not have to be constantly replaced or the equipment and machines required in the subsequent process do not become clogged, all contamination must be removed from the water circuit during cleaning. Shenzhou sludge Decanters pro with very high G force and torque handling capability are used here in the recycling industry. The washing water cleaned by this process can be fed back into the process cycle. This protects the environment and reduces production costs. Thus, an efficient separation system contributes invaluably in maintaining the water circular economy. The cleaned PET flakes are then available for further use.

Main technical features 1. Industrial design
Whole machine set design follows concept of advanced industrial design,ensures stability,functionality and safety of whole machine.Also effectively absorbs shear force of dynamic load during operation.
2. Effectively ease resonance during rotating of bi-rotor
When centrifuge works,there is no obvious first-order and two-order resonance regions within designed speed range,meanwhile ,whole vibration intensity of bearing seat is definited within 2mm/s-4mm/s.All of this eliminates extra fatigue damage to components and assembly units from high frequency vibration during operation and sudden vibration when shut down.
3. Thoroughly eliminate phenomenon of liquid ring stalling
Phenomenon of liquid ring stalling happens during heavy duty boot or shutdown process of complete set machine,especially for LW550 and even larger models,It would makes bounce or wild shake,causes extra impact fatigue damage to main bearings,screw bearings and inner parts of rotary bowl.Fortunately ,our engineers have solved this problem thoroughly.
4. Unique technique adopt in main component work-blanks
The manufacturing methods of main component work-blanks are adopt centrifugal casting technique and overall mould-making forging technique,thoroughly avoid risks such as inter-granular corrosion and relaxation of residual stress release in welding joint.
5. Main bearing selection
We use origin bearings of international first-line brands such as S-K-F,F-A-G and so on.
6. Constant temperature detection
All fashioning components and assembly units are detected in constant temperature condition,to make sure of actual processing quality meets the requirements of designed precision accuracy.
7. Inter-change ability
Whole machine physical design and processing technique adopted in critical position,ensure all assembly units and bowls of the same centrifuge model interchangeable.It is not only easy to maintain ,but also greatly improve the reliability and safety of equipment.
8. Simplyand safely in bearing disassemblement
One layer of oil film is injected into contact surfaces between bearing and work-piece by high-
pressure,during disassemblement bearing from the machine.which would fundamentally eliminate friction within different parts.As a result,it would reduce 90% of pulling force and lower the risk of damage to high-precision parts when disassemble bearing.
9.Main bearing lubrication system
There are two kinds of lubrication system for specific product models :
A thin oil lubrication
* Oil pump offers an uninterruptedly power to ensure oil works circularly;
* Jet oil lubrication constantly clean and lubricate bearings and reduce temperature;
* Oil filter system ensure lubricant's cleanliness;
* Oil pressure energy storage system ensure lubrication pump offers an extra oil supply(the pressure is no less than 0.4Mpa) for 5-6 minutes,when power fails accidentally;
* Constant temperature system is available.
B grease lubrication
* Adopt a grease with properties of extreme pressure resistance ,oxidation resistance ,abrasion resistance,water scour
resistance,corrosion-proof and high temperature resistance.
* Optional automatic grease system fills grease on main bearing at designed hours and quantity.
10. Main bearing BH device (patent design)
There are two spare safe bearings at either end of main bearing.When machine works well,they keep certain clearance from bearing inside track to chief axis.When unexpected condition occurs,main bearing got damaged or circle center deviation causing an amplitude of vibration reaches to designed clearance,safe bearings begin to work as main bearing Meanwhile,computer automatic control system would get a feedback of abnormal vibration value on bearing position immediately then activates emergency shutdown and goes a smooth shut down.This system protects machine free from damaging and ensure production safety.
11. GSRL feeding device (potent design)
New design of internal spiral core tube has got following achieves.Without reducing centrifugal acceleration,shorten triangle belt's traction time,reduce disorder of swirling flow and extend separation time.Meanwhile increases inner working pressure of centrifuge,and restrains liquid foaming.
