What role does the filter plate play in the filter press equipment?

The filter plate is one of the core components of the filter press. What role does the filter plate play during operation and what is its significance? Let's take a look at the three important functions of the filter plate of the filter press with Sudong Chemical.

First, the filter plate can increase the effective area of ​​the filter chamber wall, thereby increasing the contact area between the filter cloth and the mixed liquid, and enhancing the filtration efficiency of the filter press. Anyone who has a certain understanding of the structure of the filter chamber of a filter press knows that the filter plate divides the filter chamber into one filter chamber, and the filter cloth is attached to the filter plate. Adding the filter chamber wall is equivalent to increasing the effective filter cloth. Area to achieve the purpose of increasing filtration efficiency. It is like planting three-dimensional crops on a limited area to maximize the use of sunlight.

Secondly, the filter plate can create an effective space to store the filter cake. The filter plate of the filter press is recessed on both sides, so the space between the two pieces is used to store the filter residue intercepted by the filter cloth. Blind spots are also used on the bottom surface of the filter plate to increase the friction between the filter plate and the filter cake when the filter cake is too large, so as to better support the filter cake.

Finally, the filter plate can press the hydraulic pressure to squeeze the filter cake. For the filtrate of the filter press to dial out from the filter cloth, it is necessary to form an effective pressure difference between the two sides of the filter cloth, so that the liquid in the solid-liquid mixture can be dialed out. Therefore, the equipment needs to apply an external force to the mixture. At this time, the filter plate acts as a specific implementer to transfer the pressure provided by the hydraulic pressure to the liquid. When the filter cake needs to be squeezed and dried twice, the filter press increases the pressure again, and this pressure also needs to be implemented through the filter plate.

The above are the three functions of the filter plate in the filter press, which shows the importance of the filter plate in the filtration process of the filter press.
