Product Description:

The Ceramic disk filter, also known as a ceramic filter machine, is a highly efficient dewatering device. It primarily consists of ceramic filter plates, a roller system, an agitation system, a feed and discharge system, a vacuum system, a filtrate discharge system, a scraping system, a backflush system, an integrated cleaning system, a fully automated control system, a tank body, and a frame.

Working Principle

The core mechanism of Ceramic disk filter relies on the capillary action of microporous ceramic filter plates and a negative pressure environment to achieve solid-liquid separation. Specifically, after startup, the equipment first evacuates the interior cavity of the ceramic filter plates, creating a pressure differential between the inside and outside of the plates. This pressure differential serves as the driving force for separation.

Under this pressure gradient, the slurry in the feed tank is drawn toward the surface of the filter plates. The plates possess a key characteristic: they allow liquids to pass through while blocking air and trapping solid particles.

Solid particles in the slurry are trapped on the filter plate surface, gradually accumulating into green tea cakes. Meanwhile, the liquid passes through the micro-pores of the filter plate and, via the switching of the distribution head, flows into a dedicated vacuum tank. This step completes the initial solid-liquid separation.

As the filter plates move away from the slurry surface during operation, the vacuum remains active. It continues to extract residual moisture from the filter cake, enhancing its dryness. Subsequently, scrapers on the equipment move close to the filter plates to scrape off and collect the dried filter cake. After unloading the cake, the filter plates undergo a reverse-flushing process to remove fine particles previously trapped in the micro-pores, preventing clogging that could affect subsequent filtration. Once thoroughly flushed, the filter plates rotate back into the feed tank, re-entering the slurry to begin the next separation cycle. This continuous cycle enables uninterrupted filtration.

The advantages of Ceramic disk filter:

1. Energy-efficient and high-performance: Significantly higher processing capacity compared to traditional equipment, with notable electricity savings. Compared to older disc filter presses and external filter presses, electricity costs can be reduced by over 80%, resulting in substantial long-term cost savings.

2. Automated Control: Fully automated operation eliminates manual intervention for feeding and cleaning, reducing labor requirements and minimizing operator staffing.

3. Comprehensive Protection: Features automatic fault alarms, screen displays, high/low liquid level indicator lights, and automatic fault resolution or shutdown for manual intervention.

4. Robust and Durable Construction: Computer-optimized structural design ensures rational layout. Maintenance-free transmission components minimize downtime. Stainless steel mixing systems within the tank guarantee over 10 years of service life.

5. Enhanced Product Quality: The low moisture content of filtered concentrates significantly boosts market competitiveness while reducing transportation costs and losses.

6. Superior Environmental Performance: Clear filtrate can be reused multiple times, reducing discharge and aligning with clean production environmental trends.

7. High Filtration Precision: Ceramic filter plates typically feature micro-pores ranging from 1-5 microns, with 1.5-2.0 microns being most common. This effectively traps solid particles, achieving high-precision solid-liquid separation.

8. Superior Material Properties: The core ceramic filter plate exhibits excellent thermal stability and pore stability, featuring high strength, chemical corrosion resistance, and good cleaning/regeneration performance.

9. Capable of Processing Fine-Particle Materials: It handles a wide range of material fineness, processing materials from -200 mesh to -450 mesh or even finer.

 Where high filtration precision is required and materials exhibit high-temperature, high-pressure, or strong corrosive characteristics—conditions beyond conventional filters' capabilities—Ceramic disk filter often represent the optimal solution.
