Working principle and technical advantages of sludge dewatering machine

Working principle:

Sludge dewatering machine, especially the stacked screw sludge dewatering machine, forms continuous extrusion and shear force through the rotation of the screw shaft and the relative movement of the moving and fixed rings, so that the water in the sludge is effectively squeezed out, thereby realizing the dehydration of the sludge. In the concentration section, the sludge is initially concentrated to reduce the volume; in the dehydration section, through further extrusion and shearing, the free water and interstitial water in the sludge are largely removed to form a mud cake with a low moisture content.

Technical advantages:

High efficiency and energy saving: The stacked screw sludge dewatering machine adopts a unique design of screw shaft and moving and fixed rings, making the dehydration process more efficient and reducing energy consumption by about 30% compared with traditional dehydration equipment.

Stable operation: The equipment is made of wear-resistant and corrosion-resistant materials, operates smoothly, the noise is less than 75dB, and the failure rate is low, and the maintenance cost is low.

Self-cleaning function: The unique self-cleaning design can automatically clean the filter seam during operation to avoid blockage and ensure continuous and stable operation without frequent shutdown for cleaning. The required cleaning water volume is about 1/115 of that of the belt press and 1/62 of that of the centrifuge.

Small footprint: The compact structural design occupies only about 50% of the traditional dewatering equipment, suitable for various site conditions.

Intelligent control: The introduction of advanced PLC control systems and sensors enables remote monitoring and intelligent operation of the equipment, and can automatically adjust the operating parameters according to the properties of the sludge to improve the dewatering efficiency.

Application cases and market potential

Application cases:

Municipal sewage treatment: In urban sewage treatment plants, the spiral sludge dewatering machine efficiently dewaters the remaining sludge, reduces the sludge volume, and reduces transportation and disposal costs. Taking a large sewage treatment plant as an example, after using our sludge dewatering machine, the sludge moisture content was reduced from 98% to below 80%, and the treatment efficiency was increased by 30%.

Industrial wastewater treatment: In the chemical, pharmaceutical, food processing and other industries, the spiral stack sludge dewatering machine can treat sludge of various properties, including high viscosity, high oil content sludge, etc. Taking a chemical plant as an example, after using our sludge dewatering machine, the sludge treatment volume increased by 50%, while reducing the treatment cost.

Aquaculture treatment: In the aquaculture industry, the spiral stack sludge dewatering machine can treat organic sludge such as livestock and poultry manure, realizing resource recycling. Taking a large pig farm as an example, after using our sludge dewatering machine, livestock and poultry manure is converted into organic fertilizer, realizing the recycling of resources.

Customer value and actual benefits

Reduce treatment costs: Through efficient dehydration treatment, reduce sludge volume, reduce transportation and disposal costs. Taking a sewage treatment plant as an example, after using our sludge dewatering machine, it can save about 2 million yuan in transportation and disposal costs each year.

Improve treatment efficiency: Automated control system and continuous and stable working mode improve the efficiency and quality of sludge treatment. Taking a chemical plant as an example, after using our sludge dewatering machine, the processing time was shortened by 30%, and the production efficiency was improved.

Environmental protection contribution: It meets the national environmental protection emission requirements, reduces the difficulty of wastewater treatment, reduces the subsequent treatment costs, and contributes to environmental protection. Taking a large pig farm as an example, after using our sludge dewatering machine, livestock and poultry manure is converted into organic fertilizer, which reduces the use of chemical fertilizers and reduces agricultural non-point source pollution.
