Multi Disc Sludge Dewatering Plate And Frame Filter Press For Slurry Dehydrator

Product Specification

Multi disc sludge dewatering press & thickner for slurry dehydrator in sewage treatment

Technical introduction

Our new type volute is structured with a filter element that consists of two type rings: a fixed ring and a moving ring; and a screw that thrusts the filter element and transfers and pressurizes the sludge. The gaps between the rings and the screw pitch are designed to gradually get narrower towards the direction of sludge cake outlet and inner pressure of the filter element increases due to the volume compression effect, which thicknens and dewaters the sludge.

Multi disc screw press is clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction. It's using screw and the moving rings to clean itself as clog-free structure, and continuously operation. As a new technology that can replace the traditional filter press, like belt press, plate 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.

Features:

• The dewatering body is formed by a screw axis with fixing and moving plates overlapping, as the inner diameter of screw axis is larger than the moving plate, the moving plate do the circular motion with the screw axis to prevent clogging, to ensure the continuous operation
• Municipal wastewater, papermaking wastewater, chemical waste water, food and beverage processing waste water, industrial wastewater, papermaking wastewater, pharmaceutical wastewater, oil processing and mining wastewater, etc.
• Comparing with the traditional belt, plate& frame and centrifugal machine,volute sludge dewatering machine adopts integrated design of dehydration ontology, flocculation mixing tank and electric control device, convenient installation , small area cover, strong compatibility with ancillary equipment, greatly reduce design and the construction cost, at the same time, no need to undertake civil construction as its exquisite design.
• Can realise 24 hours automatic unmanned operation by PLC remote control , reduce the operating personnel employment and maintenance costs. At the same time, due to the exquisite design, easy operation, it is easy to learn as no special knowledge and skilled technical complex requirements.
• Main body can self-cleaning due to the special structure, threr is no need to use a lot of water for cleaning to prevent clogging. Compared with the same capacity of dewatering machine, screw rinse water consumption is only 1% of belt . The rotation speed of screw shaft is 2-5 turn/min , low power consumption. Power consumption is only 5% of the centrifuge, at the same time, no noise during operation as slow rotation speed and intermittent flush.
