Belt filter press description

Un filtro prensa de cinta es un sofisticado equipo diseñado para la deshidratación continua de lodos y fangos. Utiliza dos cintas móviles que comprimen el material entre ellas, separando eficazmente los sólidos de los líquidos. Este proceso es crucial en muchas aplicaciones industriales en las que se requiere una separación eficaz sólido-líquido.

El filtro prensa de cinta funciona según un principio sencillo pero eficaz. A medida que el lodo entra en el sistema, primero se somete a una zona de drenaje por gravedad donde se elimina el exceso de agua. A continuación, el material pasa por una zona de prensado a baja presión y, por último, por una zona de alta presión donde se produce la máxima deshidratación.

Una de las principales ventajas de un filtro prensa de banda es su funcionamiento continuo, que permite un alto rendimiento y un rendimiento constante. Las bandas, normalmente de materiales sintéticos, están diseñadas para soportar las presiones y los entornos químicos a los que se enfrentan, lo que garantiza su longevidad y fiabilidad.

Belt filter press principle

Feed Distributor: Unique, variable speed paddle wheel provides full belt-width distribution and uniform thickness.
Independent Gravity Zone: Allows for higher throughput capacity while achieving high cake solids.
Curved Wedge: Applies increasing pressure to cake with excellent cake retention to improve filtrate.
Vertical Pressure Rolls: Vertical arrangement allows for filtrate pans under each roll to keep filtrate from falling on adjacent rolls. This eliminates reabsorbtion of filtrate and improves discharge cake solids. Discharge height adequate for conveyor without raising press.
Tubular Frame Construction: Available as hot dipped galvanized, 304, 316 or duplex stainless steel. Tubular steel design for added frame rigidity, easy clean up and reduced O&M activity.
Machined bearing pads for precision frame and roller alignment.
Overall Layout: Gravity zone and controls located at operator level simplifies process optimization and eliminates costly platforms.

Belt Filter Press Advantage

Low-profile structure for a smaller machine footprint and ease of access for operator (no platform needed).
Continuously increasing pressure for perfect dewatering.
Highest throughput of up to 50% more than comparable competitor machines.
Lowest residual moisture of final product thank to extended dewatering area (7, 8 or 12 S-rolls).
Flexibility increased by modular design.
Low energy requirement, reduction of polymer consumption, ease of maintenance, and hydraulic capacity increased for significant cost savings and best operator safety.

Belt filter press features

A choice of 2 or 3 belt dewatering systems with standard, extended, or independent gravity zones for consistently high cake solids in varying sludge conditions.
When higher hydraulic sludge capacities need to be treated, the drainage zone is extended by installing a thickening stage before the actual dewatering process
Increase of the effective filtration areas.
Innovative low pressure zone concept consisting of a big diameter perforated roll substitution in the traditional wedge area.
Effective high pressure zone (increase of pressure intensity and time).
The possibility to install 5-7-9-11 rolls in final high pressure zone allows the machine to be configured per the application characteristics and required performance.

Belt filter press applications

Wastewater Treatment: Belt presses process sludge by extracting moisture, which in turn reduces the volume. Consequently, this helps lessen waste transport and disposal costs.
Food and Beverage Industry: The process uses belt presses to produce juice from fruits such as apples and grapes. These presses allow for easy extraction of the press cake from the pulp.
Mining industry: In order to minimize the amount of waste material, it needs dewatering of mineral slurries. This process includes separation, recovery, and discharge of valuable minerals.
Agriculture: Farmers need to manage animal manures or other agricultural byproducts. Consequently, they do this to reduce their water content and decrease the volume of waste.
