High Capacity Multi‑Shaft Screw Sludge Dewatering Machine

High Capacity Multi‑Shaft Screw Sludge Dewatering Machine

Brief Description

Heavy‑duty multi‑shaft screw sludge dewatering units deliver high dry‑sludge throughput up to 640 kg/h. Robust reinforced filter‑stack assembly handles large sludge volume for municipal and heavy‑industry projects, stable 24‑7 continuous dewatering with final cake moisture down to 80%.

Product Overview

High‑capacity models (DL‑302 ~ DL‑404) adopt multi‑drive screw stack structure with reinforced stainless‑steel ring components. Each complete package includes heavy‑duty dewatering host, large‑volume flocculation mixing tank, high‑flow spray washing set and industrial‑grade electric control cabinet. Larger screw‑body dimension and strengthened frame adapt for non‑stop heavy‑load working conditions. Complete technical parameters cover dry‑sludge throughput, overall dimension, net & operating weight, motor power and washing‑water flow rate.

Product Parameters

Working Principle

Mass‑volume flocculated sludge enters multi‑stack filter chamber. The front gravity‑thickening segment separates massive free water. Variable‑pitch screw spindles push sludge synchronously into high‑pressure compression zone. Terminal back‑pressure plate establishes higher system pressure for sufficient bound‑water removal. Moving rings reciprocate against fixed rings for self‑cleaning; high‑capacity spray‑washing system guarantees filter‑gap cleanness under heavy sludge load. Solid sludge cake discharges continuously.

Key Design & Performance Features

1.Max dry‑sludge throughput reaches 640 kg/h for large‑scale sludge output.

2.Reinforced stainless‑steel filter‑stack and frame for heavy‑load continuous duty.

3.Multi‑motor driving configuration for high‑volume processing.

4.Broad feed‑sludge concentration range 5000‑50000 mg/L.

5.Industrial automatic control for 24‑7 non‑stop operation.

6.Enclosed structure to contain odor for large wastewater site.

7.Clear full‑set technical data for large‑scale engineering selection.

Applications

Large municipal wastewater treatment plants, pulp & paper mills, large chemical complexes, big‑scale food processing bases, centralized industrial wastewater parks.
