Special Topic on Precautions for Using Plate and Frame Filter Presses
Thread Content
The plate and frame filter press is one of the most commonly used devices for solid-liquid separation in chemical manufacturing. However, many operational problems can arise during its daily use. Our factory primarily uses two types of such filters: those that can be washed with undercurrent flow and those that cannot. The main issues encountered in their use are as follows: 1. The filter cloths of these plates and frame filters get damaged frequently, which affects the filtering efficiency. 2. When filtering very fine colloidal substances, the filter cloth often gets clogged. 3. Accidents can occur during the washing process, and it is common for the fruits to not be cleaned thoroughly.
When filtering out fine colloidal substances, it is recommended to use a cellulose pre-coating process, which may yield better results. What is the accident in the washing process?
Reasons for the problem: Incorrect machine selection, poor machine quality, improper use
