Paperboard filter is a solid-liquid separation equipment widely used in multiple industrial fields. It stands out among many filtration equipment due to its high efficiency, energy saving, environmental protection, and precise filtration performance.

1、 Working principle of cardboard filter machine
The working principle of the cardboard filter is mainly based on filter paper as the filtering medium, and solid-liquid separation is achieved through pressure filtration. In a sealed filter cartridge, filter paper is sandwiched between horizontally placed filter plates. When liquid containing solid particles enters the filter machine, under pressure, the liquid passes through the filter paper and enters the central hole of the filter plate, while the solid particles are intercepted by the filter paper. After filtration, the residual liquid inside the filter is pressed out by compressed air or nitrogen, thereby achieving dehydration and solid-liquid separation of the filter cake.
2、 Application scope of cardboard filter machine
The cardboard filter machine is known for its wide range of applications, mainly including the following fields:
Chemical industry: used for filtering various chemical raw materials, intermediates, additives, solvents, etc., such as sulfuric acid, hydrochloric acid, nitric acid, sodium hydroxide, acetone, etc.
Petrochemical industry: In the production process of energy products such as oil and natural gas, cardboard filters are used to filter oil stains, impurities, etc.
Food industry: Impurities and particles in food raw materials such as fruit juice, beverages, alcoholic beverages, and edible oils can be filtered through cardboard filters to ensure product quality and taste.
Pharmaceutical industry: Cardboard filters play an important role in filtering impurities and particles in products such as pharmaceuticals, biological products, and medical devices, ensuring product quality and safety.
In addition, cardboard filters are also used in industries such as textiles, printing and dyeing, painting, and coatings to filter various dyes, pigments, and other raw materials, improving product quality and stability.
3、 The important role of cardboard filter in industrial production
