Centrifugal dehydrator

Huapu's equipment is mainly aimed at industrial continuous production and municipal environmental protection fields: Municipal sewage treatment: treating the biochemical sludge generated from urban domestic sewage to achieve reduced capacity for external transportation. Industrial wastewater treatment: suitable for the treatment of process wastewater and sludge generated in industries such as chemical, pharmaceutical, printing and dyeing, food processing, and brewing. River dredging and pile driving: used for mud dewatering in river and lake dredging projects, as well as rapid drying of shield tunneling mud in construction projects. Mineral processing and light industry: used for material recovery in production processes such as kaolin grading, soy protein separation, and juice clarification.

Product Introduction

Huapu centrifugal dewatering machines usually use the "horizontal spiral discharge settling centrifuge" technology, with the core function of using centrifugal force for solid-liquid separation.

Sludge dewatering: Excess sludge or industrial sludge from sewage treatment plants with extremely high moisture content is dehydrated by high-speed rotation to form a sludge cake.

Sludge concentration: Concentrate low concentration sludge to reduce its volume and facilitate subsequent processing.

Medium clarification: Recycling useful solid particles from wastewater or purifying liquids with low solid content.


Technical Advantage
Fully enclosed and environmentally friendly operation
The whole machine is designed to be sealed, with no odor leakage, ensuring a clean workshop environment and suitable for scenarios with strict hygiene requirements such as pharmaceuticals and food.
Highly intelligent automation
Adopting a PLC control system, it can achieve 24-hour unmanned continuous operation, automatically adjust differential speed, and flexibly adapt to fluctuations in feed concentration.
Compact, convenient, and easy to install
The integrated structure of pry and install has a small footprint and does not require complex civil engineering. The installation process is simple and efficient.
Efficient, energy-saving, and more economical
Strong ability to handle easily separable materials, with a higher mud production per unit time than ordinary plate and frame machines; Under the same processing capacity, the dosage of flocculant is more economical than that of belt filter press.
Process Selection

1. Confirm the nature of the sludge

Municipal/Biochemical Sludge: Due to the loose flocs of the sludge, special attention should be paid to the aspect ratio (L/D). It is recommended to choose a machine with an aspect ratio of 4.0 or above to ensure sufficient clarification and settling time.

Industrial/chemical sludge: may be corrosive or viscous, and the centrifuge material (such as 316L stainless steel or duplex stainless steel) and wear-resistant protection measures (such as tungsten carbide blades) should be confirmed.

Oily sludge: The centrifuge is relatively resistant to oil blockage, but the oil content still needs to be clarified. Please consult if a special flushing device is needed.

2. Determine the processing scale and objectives

Processing capacity: Calculate the wet sludge volume (m ³/h) or dry sludge volume (DS kg/h) that needs to be processed per hour, and select the corresponding drum diameter (such as 350mm, 450mm, 650mm, etc.).

Moisture content target: If the moisture content of the mud cake is required to be below 65% or even below 60% (usually requiring subsequent drying), it is necessary to confirm whether the centrifuge has a high dryness mode or increase the processing capacity margin when selecting.

3. Integrity of supporting systems

Fully automatic dosing system: equipped with flocculant preparation and dosing device.

Shaftless screw conveyor: automatically exports the dehydrated mud cake.

Cleaning system: The high-pressure water pump is used for automatic flushing during shutdown.
