★ Equipment Introduction

The ceramic vacuum filter is a device that achieves solid-liquid separation using vacuum suction and the capillary action of ceramic filter plates. Air is drawn from the ceramic plate chambers to create a pressure difference with the external environment. Under the vacuum, solid particles suspended in the slurry tank adhere to the ceramic plates, while the liquid passes through the hydrophilic surface of the ceramic plates into their internal chambers, achieving effective solid-liquid separation.

★ Working Principle

The filter plates immersed in the slurry tank adsorb solids through the capillary pores under vacuum, forming a layer of filter cake on the surface. The filtrate flows from inside the plates through piping to the discharge tank. A rotor moves the filter plates and the adsorbed filter cake to the drying zone, where vacuum continues to dewater the cake. After drying, the rotor moves the plates to the discharge zone (without vacuum), and a ceramic scraper removes the cake. The cleaned plates enter the backwash zone, where industrial water or compressed air flows through the backwash pipes to clean the internal pores of the ceramic plates from inside out. Periodically, ultrasonic cleaning combined with low-concentration acid ensures efficient use of the ceramic plates.
