Ultra-high Pressure Elastic Frame Filter Press

The Ultra-high Pressure Elastic Frame Filter Press is a high-efficiency solid–liquid separation system independently developed by Meiteng Technology. It uses elastomer-sealed filter bags and direct hydraulic compression to press and dewater coal slurry. The feed cake thickness is continuously adjustable from 40 to 55mm, while the filter plates are made of aluminum alloy. With a maximum pressing pressure of 10MPa, the system significantly enhances coal slurry dewatering performance.

How It Works

Independently developed by Meiteng Technology, Ultra-high Pressure Elastic Frame Filter Press dopts a plate-pressing bag filtration principle. The filter bags are sealed by “O-shaped” or “U-shaped” elastomers and compressed directly by hydraulic cylinders. During the pressing process, the characteristics of the material are fully utilized, with the filter cake transmitting the applied load. The elastomers feature free-extension ends, enabling a higher compression ratio and increasing the unit throughput of the equipment. Compared with conventional ultra-high-pressure filter presses, the system can achieve a pressing pressure of over 10 MPa, resulting in lower filter cake moisture and enhanced dewatering performance.

Applications

The product range covers medium-, high-, and ultra-high-pressure series, suitable for dewatering difficult-to-filter coal slurry and gasification slag.

Advantages

Low moisture

-It can operate at ultra-high pressing pressures of up to 10 MPa, with medium-pressure operation also available. Hydraulic cylinders apply pressure directly to the coal slurry, enabling efficient high-pressure dewatering.

-With an extra-large compression ratio of 40%, the system deeply compresses the coal slurry during the pressing cycle to achieve enhanced dewatering performance.

-Compared with conventional pressing equipment, it provides more stable pressure output and more thorough dewatering, effectively reducing the final moisture content of the coal slurry and producing a drier filter cake. This creates favorable conditions for subsequent transportation and blending.
Higher Throughput per Unit Time

-The custom-developed elastomer material features a strip-type design, with each elastomer equipped with a free-extension end. This enables stable operation at a 40% compression ratio. At this compression ratio, the system can automatically adjust the feed-layer thickness during operation, allowing production parameters to be adjusted rapidly and shortening the cycle time of each pressing cycle.
Easy Maintenance

It uses a new-generation filter cloth with warp and weft strength 4–5 times that of conventional filter cloth, delivering a longer service life and extended replacement intervals. The filter plates feature a smooth, flat surface without pronounced recesses or protrusions. The filter screen has no sharp edges or corners, reducing filter cloth wear and further extending its service life.
