Function Of Filter Plate In Filter Press

- Mar 30, 2019-

The filter plate of filter press is an important part of the indispensable equipment of filter press. In order to better reflect the filter plate of filter press plays a very important role in the process of filter press operation. We will introduce the horizontal filter presses such as box filter presses and plate-and-frame filter presses as examples.

 

The first function of the filter plate is to increase the function of the filter chamber wall, thereby increasing the area of the filter cloth attached to the filter plate. At the beginning of filter press design, in order to meet the purpose of efficient filtration, the most direct way to achieve this goal is to increase the area of the filter cloth inside the filter press, and the filter cloth must be attached to the filter plate wall, so it is necessary to increase the area of the filter chamber wall in the limited space. The filter chamber of the filter press is made up of several pieces of filter plates, each of which has an area of the surface of the filter chamber wall, and each piece of filter plate can have a corresponding filter area of the filter cloth. As long as the pressure and bearing capacity range, the effective filter area of the filter press can be increased by tens of times. This is the most important function of the filter plate of the filter press, and also the reason why all the filter press equipment can not lack the filter plate of the filter press.

 

The second function of the filter plate is to establish the middle of the storage cake. At the beginning of the design and manufacture of the filter plate, there was an inward depression design. This design is to store the space of the cake volume when the filter cloth intercepts the filter cake. The bottom blind spot is to increase the friction of the filter cake and to support the filter cake more effectively. So it seems that the filter plate plays a role of storage and support for the cake.

 

In a word, filter cloth of filter press plays an important role in setting up space for storing filter cake and enlarging the function of filter wall in the equipment, which is a necessary condition for the filter press to be used in the present high-speed industrialized production.
