Product Introduction
Adopts vertical candle filter cartridge array and PLC full-automatic control, achieving high-precision solid-liquid separation of 0.1-50μm, with filter cake moisture content ≤25%, suitable for high-viscosity and heat-sensitive materials.
Fully enclosed design (pressure ≤0.8MPa), supporting inert gas protection to meet the safety filtration needs of flammable, explosive, and toxic media.
Widely used in catalyst recovery, biopharmaceuticals, food and beverage, and other fields, replacing traditional plate and frame filter presses to enhance automation levels and yields.
Pre-Coating Filter Aid: Before filtration, diatomite/activated carbon is injected into the tank to form a 0.5-2mm filter aid layer, improving filtration precision.
Pressurized Filtration Stage:
Materials are pumped into the filter tank and pass through the filter cartridge under 0.3-0.6MPa pressure;
Solid particles are intercepted on the surface of the filter aid layer, and the filtrate is collected and discharged through the central tube of the candle core.
Filter Cake Washing (Optional): Washing liquid (water/solvent) is injected to replace the residual filtrate in the filter cake, improving solute recovery.
Backblowing and Slag Discharge: Compressed air blows off the filter cake in the reverse direction, which is discharged through the bottom butterfly valve, supporting online filter cartridge cleaning (CIP).
High-Precision Filtration: Stainless steel sintered mesh/metal fiber filter cartridges can intercept 0.1μm colloidal particles, with filtrate turbidity ≤0.5NTU.
High Yield Design: Filter cake washing efficiency ≥95%, combined with multi-stage washing process, noble metal catalyst recovery rate reaches 99.9%.
Fully Enclosed Operation: O-ring sealing + pressure balance valve prevents volatile organic compounds (VOCs) leakage, compliant with environmental regulations.
Continuous Production: Multi-tank parallel configuration enables 24-hour uninterrupted filtration, with maximum single-machine processing capacity up to 200m³/h.

Question 1: How to improve filtration efficiency for high-viscosity materials?
Answer: Preheat the material to reduce viscosity (e.g., 60-80℃ for resins) and use larger-pore (10-20μm) filter cartridges. Pre-coating with diatomaceous earth can also form a porous filter cake to prevent cake compression.
Question 2: Can the system handle flammable solvents?
Answer: Yes, the explosion-proof model supports nitrogen purging (O₂ content ≤1%), flame arrestors, and static grounding. All electrical components meet ATEX/IECEx standards for hazardous areas.
The Fully Enclosed Automatic Candle Filtration System revolutionizes solid-liquid separation with its combination of high precision, process flexibility, and safety features. By enabling continuous operation, high recovery rates, and minimal operator exposure, it sets a new benchmark for critical filtration applications in pharmaceuticals, chemicals, and food industries.
