Discover the innovative Candle Filter, a state-of-the-art automatic filtration system designed to revolutionize your liquid filtration processes. This advanced filter employs a robust cartridge framework, ingeniously enveloped by premium filter cloth and cake layers, ensuring exceptional clarity of liquids through efficient pump pressure utilization.
Tailored to meet diverse filtration needs, the Candle Filter offers versatile filter material options, expertly adapted to match varying filter media, precision requirements, and the viscosity of filter residues. Experience unparalleled filtration precision and adaptability with our cutting-edge solution.
When the slurry is pressed into the pressure vessel, its upward trajectory ensures optimal filtration. This movement is crucial as it encourages solid particles to settle gracefully onto the surface of each filter candle, forming a uniform suspension. This methodical approach guarantees the creation of a consistent and reliable filter cake.
Filter cakes develop seamlessly on the outer surface of each stainless steel candle filter element. Engineered with precision, the filter candles in each row are strategically connected at the top through both series and parallel connections. This sophisticated design is meticulously crafted to align with specific process requirements, ensuring peak performance.
The innovative discharge pipe for the slurry is linked precisely to the level set, with each set tube seamlessly attached to the primary branch line via advanced electric valves. These electronic marvels manage both filtration and reverse washing, expertly optimizing the filter cake formation of the filter candles online by meticulously controlling the flow. This elegant system allows every header slurry to be transported to the main branch line under comprehensive electric control, creating a sophisticated loop filtering process.
