Flocculant Dosing System

The 2-box and 3-box flocculant dosing device produced by our company is an automatic mechanism which doses PAM powder into
solution. By dosing in batches, the flocculant particles will be fully cured to achieve the desired results. Flocculant dosing device can be operated through electric control panel from long distance, which is safe, convenient and reliable. It has wide suitability, especially applies to municipal sewage treatment plants, industrial wastewater treatment and such industries which require the use of dosing flocculant solution. We can also meet the special needs of users by providing special design according to their requirements..

Working principle of flocculant dosing device:
Working principle of flocculant dosing device: the mixture of the PAM powder will enter into the mixing barrel through powder adding device, feed meter by jet flow. And the flocculant will be fully dissolved under the gentle agitation of the stirrer and enter into the solution reservoir through the electrically controlled valve. The solution will be taken by the dosing pump when necessary and mixed with dilution water by the mixer, then enter into the centrifuge or other separation equipments. The tiny particles will agglomerate into large particles under the effects of the flocculant to achieve the purpose of solid-phase separation. In the treatment of industrial wastewater and municipal sewage, adding flocculant will improve the processing capacity of separation equipments. During operation, the amount of water and dosing amount can be regulated through valves and the dosing pump, to achieve a satisfactory separation effect and economic effect.

 

Automatic Control System

PLC electrical control system
The PLC electrical control system for dewatering complete equipments developed by our company is very suitable for situations withcomplex material dewatering process and high technical requirements. This system has a very high degree of automation and field unattended operation is possible. It can display a variety of main process parameters and has nearly 30 functions such as the monitoring and alarm of each equipment abnormal state and interlock protection, make the entire working system more safe and reliable.
PLC + PLC electrical control system
The above-mentioned PLC electrical control system can network and communicate with the field PC through the communication interface or with the PC in the center control room through the user-specified network communication method, and achieve dynamic display of the equipment status and printing production reports and other functions.
PLC + man-machine interface electrical control system
This system has a touch screen for operations and display of parameter measurements which can generate dynamic images, alarm scroll and password login. And relevant process parameters can be modified and downloaded via the touch screen.

The electrical control system for the sludge dewatering complete equipments developed by our company basically has the following four types: Simple electrical control system: This electrical control system can implement automatic/manual operation on the separation main machine system, feed system, dosing system as well as the dispensing system, and has functions like main equipment operation monitoring, fault alarm and interlock protection, etc. This system can meet the control requirements of single equipment.

Sludge Conveying System

Screw conveyors are widely used in areas such as wastewater treatment and industrial production. LSS series screw conveyors are
designed to be shaftless. The U-shaped conveying trough is enclosed with its top cover can be opened. Therefore, it is especially
suitable for conveying pollutant, odorous, dangerous, bridging as well as cleaning materials. LSS series shaftless conveyors
convey materials through a strong rotating steel helix. It can effectively convey dry, wet, sticky, powdery and rough materials.
The design of LSS series shaftless screw can effectively prevent congestion and twisting. The design of LSS series shaftless screw
can effectively prevent congestion and twisting.centrifugal machine for oil

Sludge Feed System

The sludge feed system consists of sludge cutter, sludge feed pump, electromagnetic flow meter, electric valve, manual valve, pipes, concentration meter in the quenching and tempering pool, ultrasonic level meter, turbidimeter at the outlet of separation medium, and other parts.

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 .

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.
