一、Product Introduction
The Haipuou Environmental Protection Multi-Disk Screw Press is a new type of professional sludge thickening and dewatering device featuring fully automated, non-clogging, and continuous operation capabilities. Developed based on the unique principles of staggered disk movement and screw-driven compression dewatering, it effectively resolves common industry pain points associated with traditional plate-and-frame or belt presses, such as frequent clogging, complex maintenance, and poor adaptability. The equipment features a streamlined, compact structure comprising a screw drive shaft, fixed rings, moving rings, a back-pressure plate, a drive system, and an electrical control system. Through dynamic mechanical interaction, it performs the entire process—sludge thickening, compression dewatering, and automatic cleaning—in a single integrated operation. It currently stands as a mainstream, intelligent, and eco-friendly solution for sludge volume reduction in municipal sewage and industrial wastewater treatment.
The equipment's operation consists of three core stages, all running automatically in a closed-loop system without the need for manual intervention: First, the gravity thickening stage: the screw drive shaft rotates continuously, driving the surrounding multi-layered fixed and moving disks to shift relative to one another. As sludge enters the unit, gravity causes water to filter rapidly through the gaps between the disks, achieving quick thickening and significantly increasing the sludge's solid content. Second, the screw compression dewatering stage: the thickened sludge is conveyed forward by the screw shaft. The equipment utilizes a design with variable pitch and variable gaps (wider at the inlet, narrower at the outlet), causing the volume of the screw chamber to gradually contract. Combined with the outlet back-pressure plate, this creates controllable internal pressure that continuously compresses the sludge and expels internal moisture, steadily increasing the solid content of the sludge cake to achieve stable, continuous dewatering. Third, the dynamic self-cleaning stage: the rotation of the screw shaft drives the moving rings in a continuous reciprocating motion. The dynamic friction generated by the staggered movement between the fixed and moving rings ensures automatic, continuous cleaning of the equipment. This fundamentally eliminates the risk of clogging in the filtration gaps, removes the need for high-pressure spray cleaning, and enables stable, continuous 24-hour operation.
二、Product Advantages
1. Dynamic self-cleaning mechanism; completely eliminates clogging
Unlike traditional sludge dewatering equipment, the multi-disk screw press features a unique dynamic self-cleaning structure. It relies on the continuous relative movement between fixed and moving rings to clear sludge residue from the gaps between disks in real-time. This eliminates the need for manual cleaning or high-pressure water rinsing, effectively solving the common issues of clogging and frequent downtime for maintenance found in traditional equipment. The system supports long-term, continuous operation with an extremely low failure rate.
2. Integrated thickening and dewatering; compact footprint and high efficiency
The equipment integrates sludge thickening and dewatering functions into a single unit, eliminating the need for auxiliary civil engineering structures such as thickening or sedimentation tanks and complex pre-treatment processes. It features a compact design with a minimal footprint. Capable of directly processing low-concentration sludge, it autonomously completes the entire thickening and dewatering workflow with high efficiency, significantly reducing civil engineering investment and site costs.
3. Low-speed, quiet operation; significant energy savings
The equipment utilizes a low-speed screw extrusion process; it has no high-speed rotating parts, resulting in vibration-free operation, minimal noise, and ultra-low energy consumption. Compared to traditional belt or plate-and-frame dewatering equipment, it offers drastically lower power consumption and reduced daily operating costs. It is ideally suited for long-term, large-scale sludge disposal operations, delivering outstanding cost-effectiveness through energy efficiency.
4. Fully automated and unattended operation; simple, worry-free maintenance
Equipped with an intelligent electronic control system, the unit enables 24-hour continuous, fully automated operation—including sludge feeding, thickening, pressing, and discharge—without the need for dedicated on-site personnel. Featuring a robust structure and no easily worn parts, the equipment boasts a low failure rate and requires minimal daily maintenance, significantly reducing labor and operational costs.
5. Broad adaptability and strong resistance to load fluctuations
The system is highly adaptable to diverse sludge conditions, capable of stably processing complex sludge types—including low-concentration, high-viscosity, oily, and impurity-laden sludge. It handles fluctuations in sludge concentration and flow rates with ease, demonstrating excellent resistance to shock loads. It is particularly well-suited for soft organic sludge and oily sludge that are difficult for traditional dewatering equipment to process, consistently delivering stable dewatering performance and uniform sludge cake formation.
