Gürtel Filterpresse

In consultation withGerman and Japanese manufacturers of structural design technologies andbelt type filter presses, Jiangsu Lingzhi Environmental Protection Co Ltd (Lingzhi) has manufactured the first belt type filter press in China with multi-layer layout of the roll mandrel. This filter press design is rational and ensures high efficiency along with easy maintenance. With its' horizontal layout of roller mandrel belt type filter press also rectifies a defect in the traditional belt type filter press. This design is distinctive for a multi-stage dewatering technique. The sludge cakes produced contain low moisture level. Applying this leading dewatering technology in the transition dewatering section, the belt type filter press will prevent the problem of sludge leaking from both sides of the belt when there is a large volume of sludge. As the self-cleaning stainless steel nozzle is used for the washing system of the belt strainer, water from the secondary sedimentation tank could be used for washing. Dirt in the nozzle will be cleaned by the nozzle itself. Thisensures lower operation costs. The belt type filter press has good anti-corrosion performance. All fasteners are made of stainless steel. It is equipped with an automatic unit for anti-deflection of the belt strainer and the pressure regulation unit. Both sides of the belt strainer are designed for anti-deflection. The sludge feeding volume, belt tension, belt speed and dosage of the filter press can be adjusted according to specifications or requirements to optimize productivity and dewatering rate. The belt filter press has been widely used in different types of wastewater treatment. It has a unique design which facilitates multi-stage dewatering, and the sludge cake produced has a low water content ratio. This equipment can run continually at low revolution speed and high efficiency. It is also easy and safe to operate. The working process of belt filter press consists of four phases: 1. Pre-treatment: sludge thickening by force of gravity to increase sludge concentration and reduce volume. Sludge settles after being mixed with flocculation agent to form floc. 2. Gravity dewatering: The pre-treated sludge is then fed to the belt strainer of the filter press. The water is filtered out of the belt by force of gravity. 3. Wedge dewatering: Following the gravity dewatering process, sludge enters the wedge section for dewatering. Following the first two stages, the sludge has lost its fluidity and is ready for pressing dewatering. 4. Roller pressing dewatering: Sludge is squeezed by different rollers repeatedly andbecomes sludge cakes with low water content ratio. The sludge cakes are lastly discharged to the outlet automatically.
