III. Technical characteristics of the centrifuge
Not only equipment manufacturer but also system engineering service provider
With strong technical strength and rich engineering experience, we are fully qualified for the turnkey project of the sludge
dewatering room. We are also willing to recommend the design layout of the sludge dewatering room for owners and design institutes.
Eddy current type spiral outlet
The outlet of the screw conveyor adopts a vortex type to accelerate the entry of materials into the rotating drum, thereby
reducing the disturbance of the discharged materials to the formed solid phase layer and improving the processing capacity. In the industry of flocculant, it can effectively reduce the shearing effect of the discharge hole on the floccules under the high-speed discharging state, so as to reduce the consumption of chemical agent.
BD board technology
The screw conveyor adopting BD board technology is the most advanced for reducing the water content and improving the solid recovery rate of activated sludge (organic matter ≥ 40%). The technology has the following advantages:
• Increase the depth of the liquid layer, the effective settlement area, and the processing capacity of the centrifuge;
• Reduce the moisture content of the sediment under the action of spiral high-pressure extrusion;
• Improve solid recovery rate and make the clear liquid clearer;
• Save the consumption of chemical agent and cut down equipment operating cost;
• Compared with the common centrifuges of the same separation performance, it is lower in operating speed and requires less power consumption.
More economical in equipment investment and later-stage operation
Goal: Minimum equipment operation, maintenance and repair costs;
We are committed to creating the best quality and most cost-effective China-made centrifuge brand. We recognize that stable operation of equipment is the guarantee of greater benefits for customers, and outstanding suppliers and modern processing equipment are the basic guarantee for quality centrifuges. Advanced and unique technology is the guarantee to reduce operating cost, in addition to high-quality wear resistance, eddy current type spiral outlet, circular arc slag outlet, special spiral structure, advanced electrical control technology, etc.
High performance wear-and corrosion-resistant cemented carbide
There are inevitably small hard particles and impurities such as sand, glass, and metal in sewage. If the centrifuge does not adopt a reliable wear-resistant configuration, its service life and operational stability will be greatly affected. The
wear-resistant solution is completely targeted. According to the material characteristics (pH value, corrosive substance, solid particle size hardness, etc.), cemented carbide or ceramic can be selected, and the cemented carbide can be either YG6, YG8, or various modified tungsten-cobalt alloys with the hardness of 89~93 (HRA), which can fully meet the application fields of the centrifuge.
Reduce the moisture content of the sediment under the action of spiral high pressure extrusion
High-dryness screw conveyor and drum structure
The dehydration of solid particles relies mainly on strong centrifugal force, high-torque screw extrusion force (pushing torque), and ultra-long solid particle dehydration length. The centrifuge can generate centrifugal force exceeding thousands of G, 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.
Fluids Outlet position Alloy wear plate
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.
Humanized centrifuge configuration
1.Spiral bearing (in the drum, concealed) lubrication technology: the lubricant is filled from the outside of the hood.
2,The hood adopts a hinged opening structure and is equipped with a high-pressure gas strut to assist the opening.
Variable pitch technology
Constant torque control technology
The constant torque control of the centrifuge is the most advanced control mode in the world. The real-time monitoring of the actual output torque of the constant torque variable frequency motor through the high-performance auxiliary inverter is compared with the set torque value, and PID is used to adjust the material pushing speed of the screw conveyor in real time. The centrifuge can achieve continuous, stable, and economic operation.
