101,131,132污泥脱水叠螺机/sludge dewatering crew press

叠螺式污泥脱水机遵循了力水同向、薄层脱水、适当施压及延长脱水路径等原则，解决了前几代污泥脱水设备易堵塞、无法处理低浓度污泥及含油污泥、能耗高、操作复杂等技术难题，实现了高效节能的脱水目标。脱水机可在全自动运行的条件下，实现高效絮凝，并连续完成污泥浓缩和压榨脱水工作，最终将收集的滤液回流或排放。广泛用于市政污水处理工程以及食品、淀粉、油脂、制药、化工、造纸、皮革等行业的水处理系统。

结构原理

叠螺式污泥脱水机集全自动控制柜、絮凝调质槽、污泥浓缩脱水本体及集液槽于一体。主体是由固定环和游动环相互层叠，螺旋轴贯穿其中形成的过滤装置。前段为浓缩部，后段为脱水部。固定环和游动环之间形成的滤缝以及螺旋轴的螺距从浓缩部到脱水部逐渐变小，螺旋轴不断带动环清扫滤缝，防止堵塞。螺旋轴的旋转在推动污泥从浓缩部输送到脱水部的同时，以及背压板的阻挡作用下，产生极大的内压，容积不断缩小，达到充分脱水的目的。

Multi-plate Sludge Dewatering Screw Press belongs to the screw press, it's clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction. HLDS using screw and the moving rings to clean itself as clog-free structure, and controlled by the PLC automatically, it's a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sludge dewatering machine.The Sludge Dewatering Screw Press can be provided with all equipment required for dewatering included and factory mounted, piped and wired on asingle stainless steel skid. This equipment includes the sludge pump, washwater pump, polymer dosing system and control panel. The system features fully automated one pushbutton startup and shutdown. Once started up the system can run unattended and can be set to shutdown automatically with no operator intervention.

Working Principles

The conditioned sludge flows into the filter zones from the flocculation tank and is pushed forward

to the discharging end. With the gaps between the thread of the shaft is getting even narrower,the pressure

on the sludge is getting higher and higher. Then the water is separated from the sludge  and flows out from

the gaps between the moving rings and fixed rings. The movement of the moving rings will clean the gaps

between moving and fixed rings and prevent the machine from blockage..

The filtered sludge cakes will be pushed forward by the shaft and finally discharged from the end.

Technology Advantages

1. Configurating exclusive spiral plate forpre-concentration and better for treating low concentration sludge.

2. Low speed operation, low noise, low energyconsumption, only 1/8 of the belt type, 1/20 of the centrifuge

3. Rings substitute filter cloth, selfcleaning, no clogging, easy treatment  of oily sludge

4. Reduce the cost of infrastructureinvestment, improve the results of treatment

5. Fully automatic control, easy operation andmaintenance
