Quotation for COEX-120/120 Double-stage Ceramic Extruder

A. Ceramic ultrafiltration membrane product

Ceramic ultrafiltration plate membrane can effectively remove organic matter, suspended matter, toxic and harmful substances (such as radium, arsenic), microorganism, algae and oil in liquid, and is the core and key component of new efficient separation technology.It is a kind of ultra-fine filter membrane with asymmetric structure, which is prepared by sintering process with inorganic materials such as alumina. Compared with the traditional organic membrane, it has the advantages of good chemical stability, good reliability, long service life, small occupation space, excellent pollution resistance and low energy consumption, which represents a development trend of water treatment membrane materials.

The service life of ceramic flat film is 3~5 times longer than that of polymer film, the membrane flux is 3~10 times higher, the consumption of chemical agent is reduced by 50 times, the cost of operation and maintenance and energy consumption are reduced by more than 50%. the contamination, chemical cleaning and oxidation of polymer ultrafiltration membranes are an inevitable conundrum, while ceramic membranes are easier to clean, more resistant to contamination, and there is no risk of oxidation. 

Our company overcome difficulties, based on German EAC-Elektro company alumina ceramic membrane extruder technology of double-stage vacuum exhaustspiral ceramic ultrafiltration membrane extruder model VAHRS 120B, to meet the needs of domestic users. Not only we use better cost-effective manufacturing materials that our extruder could be cheaper, but also we have further developed the technology of ceramic extruder, such as we fully localized extruder optimizes the structural design of the replacement module and facilitates the maintenance of the extruder and the vacuum chamber structure design is optimi zed to eliminate the defects such as possible leakage pressure due to deformation. Therefore, the extruderis superior to imported extruder in some performance.

D. Configuration and characteristics of COEX-120/120 Double-stage vacuum exhaust spiral ceramic plate(Pipe) extruder:

We make the COEX-120/120 Ceramic plate (tube) extruder, the first pursuit of configuration is the stability and reliability when the extruder in process. The second goal is to give full play to the advantages of our first brand of extruder heart parts in China, we use the PM-HIP stainless steel imported from Europe to get a high corrosion resistance and high wear resistance feature, to get a longer service life of extruder. Modular design is used in the designing of core components to facilitate the replacement of easily damaged parts and reduce the maintenance cost of extruder.

According to the above ideas, our COEX-120/120 ceramic extruder configuration as follows:

Power system

Motor/ reducer combination

Two stage extruders equip high-endandhigh-torque variable-frequency speed regulating motor made in China, It has characteristics of compact, not occupy position, large load torque, stable and reliable, and long service life.

Transmi-

ssion system

Distribu-

tion box

The radial bearing of torque distribution system adopts NSK bearing, gear is high speed heavy load hard tooth surface, gear shaft material 20 CrNi2MOA with HRC 58~62

Extrusion system

Feeder

Stainless steel hopper, stainless steel hardened driven screw forced feeding structure in counter-rotating way.

Double-stage barrel

External circulation constant temperature water control temperature, internal replaceable wear-resistant corrosion-resistant stainless steel lining combined barrel.

Double-stage screw

Hardened stainless steel screw elements and some HIP screw elements combine on top-wear position. Inside second stage screw core, a soft water circulation to be designed for strengthening temperature control.

Exhaust system

Vacuum exhaust

A world leading vacuum pump professional manufacturer Germany Busch brand to be equipped, innovative technology of oil-free claw vacuum pump, to ensure a strong, economic, efficient, reliable and mute operating state, with high efficiency, no oil, no contact operation, no maintenance of high-end performance.

Tempera-

ture control system

Accurate tempera-ture control

One air-cooled dual-system chiller is mainly equipped with compressors imported from Europe, America and Japan, Danish Danfoss and American Eco throttle parts, and high efficiency evaporators and condensers. The normal temperature water is cooled to the set temperature through the compression mechanism of the chiller to control the operating temperature of each barrel and screw section of the extruder.

Electronic control system

A touch

control screen plusa

vertical electric control cabinet

A windows 10 inch high-end, high stability and reliability touch screen

made in China to be equipped, with PLC programmable logic controller

mainframe, accurate control of the system, from the main motor of the

firststage extruder to the vacuum pump, andwiththe main motor of the

secondstage extruder, the PID setting linkage control is realized.

Dual-stage control system operation control function and main

configuration are as follows:

1. For upper stage extruder, based on the screw speed set on the touch

screen, PLC programmable logicc ontroller to control the frequency

converter to drive 11kw main motor, to realize the first-stage extruder

interlocking power control;

2. For bottom stage extruder, based on the screw speed set on the touch

screen, PLC Programmable logic controller to control the frequency

converter to drive 18.5kw main motor to realize interlocking power

control;

3. All the control cabinet devices, including contactors, air switches and

solid state relays, most adopt high-end brands of Schneider, pressure

sensor adopts American Dynisco brand, to pursue the stability and

reliability of the control system. The functions of under-pressure

protection and early warning, pressure protection and early warning of

extruder are designed at the same time. The working temperature of 5℃

~35℃set by the control cabinet itself is protected and early warning

function is realized

*Note: Above double-stage vacuum exhaust spiral ceramic extruder is not equipped with mold die.
