What are the Types of Filter Presses?

Filter Press has become an indispensable equipment in many industrial fields with its unique working principle and wide range of applications. The following introduces several common types of filter presses.

1. Plate and frame filter press

Structural features: A group of filter chambers are composed of alternately arranged filter plates and filter frames. The surface of the filter plate has grooves, and its protruding parts are used to support the filter cloth. There are through holes on the corners of the filter frame and the filter plate, which form a complete channel after assembly.

Application: Suitable for solid-liquid separation of various suspensions, especially for suspensions with high compressibility or nearly incompressible filter residues. The solid particle concentration of suitable suspensions is generally below 10%.

2. Belt filter press

Structural features: It consists of roller drum, filter belt, filter belt tensioning system, filter belt deviation adjustment system, filter belt washing system and filter belt drive system.

Application: Suitable for processing a large amount of solid-liquid mixtures, with the advantages of large processing capacity, good filtration effect and high degree of automation.

3. Diaphragm filter press

Structural features: A diaphragm is added to the plate and frame filter press to improve the filtering effect and reduce the moisture content of the filter cake.

Application: It is suitable for processing high-concentration or high-viscosity solid-liquid mixtures, with advantages such as good filtering effect and low filter cake moisture content.

There are many types of filter presses, and each type of filter press has its unique structural characteristics and scope of application. In practical applications, the appropriate type of filter press should be selected according to specific needs and conditions.
