Introduction to the Mechanism of Ceramic Filter Plates

Ceramic filter plates are a common type of solid-liquid separation equipment used for processing suspended solids, cells, high molecular substances, etc., in various liquids. They help us achieve processes such as filtration, clarification, purification, and dehydration of liquids. This article will mainly introduce the mechanism and principles of ceramic filter plates.

Construction of Ceramic Filter Plates

Ceramic filter plates are composed of several ceramic annular plates with equal spacing between them, and the inner diameter of the channels in the plates is about 1.2mm. The material of ceramic filter plates is generally aluminum oxide, and the manufacturing process is mostly slip casting. The resulting filter plate has precise pore size, high smoothness, and better separation effect for small particles.

Ceramic filter plates are a sealed structure, with liquid inlet and outlet on one side each. When liquid enters the filter plate, under the action of the pore size of the filter plate, the liquid passes through the plate pores, while solid particles deposit on the surface of the filter plate, forming a solid layer. When the solid layer accumulates to a certain thickness, the filter plate no longer functions, and it needs to be stopped for cleaning.

Filtration Principle of Ceramic Filter Plates

The filtration principle of ceramic filter plates is mainly achieved through the pore size of the filter plate. When liquid passes through the pores of the filter plate, suspended particles, high molecular substances, or cells in the liquid will be restricted and cannot pass through the filter plate, but are intercepted on the outer surface of the filter plate, forming a solid layer. The formation of the solid layer is a dynamic process, and the thickness of the solid layer gradually increases with the increase of filtration time. When the thickness of the solid layer reaches a specified value, the Ceramic Filter Plate needs maintenance and cleaning to restore its filtration efficiency.

Application Range of Ceramic Filter Plates

Ceramic filter plates are widely used in industries such as biopharmaceuticals, chemical engineering, food and beverage, and environmental protection. They can be used for filtration and separation of various substances such as paint resins, polymers, strains, yeasts, syrups, starch, juices, pulps, wines, and sewage.

Ceramic filter plates have the advantages of simple structure, good stability, reliable performance, convenient operation and maintenance, thorough cleaning, corrosion resistance, high temperature resistance, long service life, and high filtration accuracy. They can provide better filtration, clarification, and separation processes for various substances produced by users, ensuring the stability and consistency of product quality.

In summary, ceramic filter plates are efficient, environmentally friendly, energy-saving, easy to operate, and maintain solid-liquid separation devices. They not only improve product quality but also help protect the environment and reduce production costs. Their application in industrial production has broad development prospects.
