Working Principle of chamber filter press

The chamber filter press is a type of intermittent filtering equipment that plays a crucial role in various industries, including petroleum, chemical processes, metallurgy, pharmaceuticals, sugar production, mineral processing, food, and sewage treatment. Its design incorporates two adjacent concave filter plates, making it an efficient tool for solid-liquid separation across different suspensions. The following sections will detail its working principle.

The operational core of the chamber filter press involves a series of filter plates that create distinct filter chambers where processing occurs. Each plate has a design that incorporates pits and pins, offering support for the filter cloth that acts as a sealing barrier. The plates are equipped with through holes situated at the center and corners, forming a continuous channel for suspension entry, wash water, and filtrate discharge.

When the feeding pump exerts pressure, it directs the liquid mixture to each filter chamber, where the solid and liquid components are effectively separated by the filter medium. Different industries may require various types of filter cloth, ensuring optimization for their specific applications. Over time, a filter cake develops on the filter cloth as the chamber fills, with the liquid successfully passing through to flow along the channels to the designated outlet.

After reaching the filtration completion stage, the filter can be cleansed with fresh washing water. Compressed air may also be introduced to eliminate any residual washing liquid. Following this, the filter press is opened to facilitate the removal of the filter cake, which is situated between the adjacent plates, and the filter cloth is cleaned in preparation for the next cycle.

The early versions of the filter press featured a fixed filter cloth on the plate frame, but one of the primary advantages of the chamber filter press is the ease of replacing the filter cloth itself. Characterized by high efficiency and effectiveness, the chamber filter press is built to last under the same operational conditions while maintaining a high degree of automation. This includes automated cleaning processes for the filter cloth, which limits the frequency of necessary replacements.

With its established reliability, the chamber filter press has emerged as a vital piece of dewatering equipment, extensively utilized in industrial and environmental applications, particularly in the treatment of sewage sludge. Employing this technology can significantly enhance operational efficiencies in enterprises.
