Screw Press Sludge Dewatering Machine
Product introduction
Screw press sludge dewatering machine integrates an automatic control cabinet, flocculation and conditioning tank, sludge thickening and dewatering body, and liquid collecting tank which can realize efficient flocculation under the condition of automatic operation, and continuously complete the sludge thickening and pressing and dewatering work, and finally return or discharge the collected filtrate.
Core Technology


Concentration
The fixed ring and moving ring moved relatively with the screw shaft rotated.
Under gravity, sewage follows from the gap between the fixed ring and the moving ring to achieve rapid concentration.

Dewatering
The concentrated sludge moves forward continuously with the rotation of the spiral axis. Along the exit direction of the sludge cake, the pitch of the screw shaft gradually decreases, the gan between the rings also gradually decreases, and the volume of the spiral cavity keeps shrinking, Under the action of the back pressure plate at the cutlet, the internal pressure gradually enhanced, and under the continuous operaton gf the crew dreaming shaft, the water in the sludge is extruded and discharged the solid content of the filter cake is continuously increased, and the continuous dehydration of the sludge is finally achieved.

Self-Cleaning
The rotation of the screw shaft drives the floating ring to rotate continuously, and the equipment relies on the movement between the fixed ring and the floating ring to achieve a continuous thus subtly avoiding the blockage problem common in the traditional dehydrator.

Sludge Dewatering Equipment industry knowledge

As an innovative equipment in the field of sewage treatment, the spiral laminated sludge dewatering machine has become an indispensable industrial treatment equipment in the environmental protection industry with its unique design concept and efficient performance. Qingben Environmental Protection Technology (Jiangsu) Co., Ltd. focuses on the manufacture of sludge and wastewater treatment equipment. Today's solid-liquid separator has developed into an efficient dehydration system integrating mechanical manufacturing, material science and intelligent control technology, and is widely used in industry and emerging environmental protection fields.

The laminated sludge dewatering machine integrates automatic control cabinet, flocculation conditioning tank, sludge concentration and dehydration body, and liquid collection tank. It realizes efficient flocculation under automated operation, continuously completes sludge concentration, squeezing and dehydration, and finally returns or discharges the collected filtrate. The solid-liquid separator separates the solid and liquid in the mixed liquid by physical or mechanical means, and plays a key role in resource recovery, pollution control and production efficiency improvement. Today, the spiral laminated sludge dewatering machine has derived a diversified technical route, covering a wide range of scenarios from traditional manufacturing to emerging environmental protection industries.

In the future, solid-liquid separators will develop in the direction of modularization and integration. Mobile dehydration units can be quickly applied to emergency treatment scenarios, such as sewage treatment after disasters. The rotation of the spiral shaft drives the floating ring to rotate continuously. The equipment relies on the movement between the fixed ring and the floating ring to achieve continuous dehydration, cleverly avoiding the common blockage problem of traditional dehydrators. Stricter environmental protection regulations promote technological innovation, but high-concentration and low-flow sewage treatment and particle separation accuracy improvement are still the focus of technological breakthroughs, which require interdisciplinary research support such as materials and fluid mechanics.

As an important technical carrier for industrial construction, the spiral laminated sludge dehydrator has completely changed the sludge treatment process. With the deepening of the "dual carbon" strategy, this technology with both mechanical precision and environmental friendliness will continue to release innovative vitality in the global environmental protection industry.
