　　Special centrifugal sludge dewatering machine for sewage treatment plant

　　Overview:

　　The sludge from sewage treatment plants is generated during the purification and preparation of drinking water. Dealing with these sediment sludge will incur high transportation and disposal costs.

　　The use of Lishui Ruichen centrifugal sludge dewatering machine technology can reduce these costs - confirming our slogan: designed specifically for your success.

　　Lishui Ruichen achieves sustainable drinking water treatment

　　Drinking water is an undeniable wealth for many people. On average, each person consumes several hundred cubic meters of water per year. A report by the United Nations (2015 World Sustainable Development Water Use) predicts that the world population will reach 9.1 billion by 2050. The population in 2015 was approximately 7.3 billion. The rapid population growth has a huge impact on the availability of drinking water. For more and more people, drinking water will become a very precious thing.

　　Therefore, the treatment and purification of wastewater have become even more important.

　　Lishui Ruichen is committed to the wastewater treatment industry and develops solutions for centrifugal sludge dewatering specifically for sewage treatment plants. The provided separation technology.

　　Centrifugal sludge dewatering machine uses a working speed higher than the standard centrifuge to achieve higher separation factor, more efficient separation, higher supernatant clarity, and greatly improve solid recovery rate. Our company has conducted in-depth research on the principles and structural structures of centrifuges and developed a full range of high-speed centrifuges, which can meet the material separation requirements under different working conditions and are the choice for solid-liquid separation.

　　The main unit of the centrifugal sludge dewatering machine consists of a rotary drum, a screw propeller, a large end support plate, a small end support plate, a differential, a main drive motor, an auxiliary drive motor, a hydraulic coupling, a bearing seat, a rotating body cover, a transmission cover, a transmission belt, a control box, and a base. The drum and propeller are the core components of the centrifuge, where the solid-phase separation of sludge mixture is carried out. (As shown in the above picture)

　　Process flow of centrifugal sludge dewatering machine for sewage treatment plant:

　　(1) Sludge feeding system: This system consists of a sludge cutting machine, sludge feeding pump, electromagnetic flow meter, manual valve, etc.

　　(2) The flocculant dispensing system: This system consists of a booster pump, a jet pump, a dispensing tank, a storage tank, a mixing ball, a dosing pump, a rotor flowmeter, and pipelines.

　　(3) Separation host: Large aspect ratio horizontal screw centrifuge (dehydration type, concentration and clarification type)

　　I. Differential configuration: Mechanical differential: Differential is adjusted by replacing the pulleys, with an adjustment range of 5-25 r/min

　　II. Mechanical differential with ten double frequency converters: The left speed is infinitely adjustable with a frequency converter, with an adjustment range of 5-25r/min and an alarm.

　　(4) Cement cake conveying system:

　　I. Shaftless Spiral Conveyor: The material of the conveyor is stainless steel; Inner cushion ABS, spiral shaftless type. Conveyor length according to user requirements

　　Fixed, single conveyor length ≤ 10m, inclination ≤ 25 °

　　II. Alternatively, a sludge transfer pump can be used: an imported sludge transfer pump can directly transport the separated sludge to a designated location.

　　(5) Electrical control box:

　　The electrical control box is equipped with imported frequency converters and related electrical components for separating the main engine speed regulation.

　　II. Function: Rotary drum variable frequency speed regulation, start stop switch for agitator, cutting machine, sludge pump, screw conveyor, display of current, voltage, flow rate, and accumulated running time. This function is used to control the operation of the entire dehydration system.
