Filter Press With Flex And Vibration

Filter Press with flex and vibration is suitable for materials with large viscosity and difficult to automatically fall off.

The filter cloth varicose system developed by our company can enable the filter press to change the inclination angle of the filter cloth during operation to form an inverted V shape, and at the same time, the springs held on the filter cloth expand and contract to generate vibration, so that the filter cake will fall off automatically. The varicose rod is made of reinforced polypropylene, which is light in weight, corrosion-resistant, flexible in movement and easy in maintenance. The varicose vibrating filter press is suitable for materials with high viscosity and difficult for the filter cake to peel off automatically.

This machine is widely used in wastewater treatment in various industries, such as food wastewater treatment, slaughterhouse wastewater treatment, meat processing sludge dehydration, cooked food processing factory wastewater treatment, soybean product wastewater treatment, urban sewage treatment, papermaking sludge dehydration , chemical fiber textile printing and dyeing sewage treatment, petrochemical sewage treatment and sewage treatment plants and other industries that require solid-liquid separation.
