Boasting rapid discharge, a high degree of automation, and low labor costs, it is widely suited to high‑throughput, continuous‑production applications. Linked plate‑pulling mechanism: Featuring an extended hydraulic cylinder paired with a chain‑or‑slide linkage system, all filter plates are connected via hook‑type or L‑shaped chain plates. When the pressure plate retracts, it simultaneously pulls all plates apart at equal intervals, eliminating the need for an empty return stroke. Discharge time is reduced by more than 60% compared with conventional single‑plate pulling. Auxiliary discharge ensures more thorough cake removal: Standard equipped with an automatic rapping device, which periodically lifts and drops the filter plates after they are opened, using vibration to facilitate rapid cake release and preventing plate adhesion and manual slag removal.

Description

Boasting exceptional features such as ultra‑fast unloading, a high degree of automation, and low labor costs, it is widely suited to high‑throughput, continuous‑process production environments.

Linkage plate‑pulling mechanism: Utilizing an extended hydraulic cylinder combined with a chain‑and‑slide linkage system, all filter plates are connected via pull hooks or L‑shaped chain plates. When the pressure plate retracts, it simultaneously and uniformly separates all filter plates at equal intervals, eliminating the need for an idle return stroke. This reduces discharge time by more than 60% compared to conventional single‑plate pulling methods.

Auxiliary discharge for more thorough cake removal: Standard equipped with an automatic rapping device; after the filter plates are opened, a pawl periodically lifts and drops them, using vibration to ensure rapid cake release, eliminating plate sticking and manual slagging.

Ultra-high-pressure self-locking diaphragm filter press

Centered on mechanical self‑locking and ultra‑high‑pressure pressing, it achieves deep dewatering of coal sludge with high efficiency, stability, and energy savings. In the coal industry, it is the preferred equipment for meeting environmental standards, enabling resource recovery, reducing costs, and boosting productivity, thereby significantly enhancing both the overall economic performance and environmental compliance of coal preparation plants. Mechanical self‑locking clamping system (core technology): After hydraulic cylinders apply pressure, the system automatically locks in place, eliminating the need for continuous pressure maintenance. This thoroughly addresses common issues in conventional models—such as filter plate loosening, material leakage, and excessive energy consumption under high pressure. Once locked, the hydraulic system shuts down, eliminating ongoing energy use and delivering 40%–60% greater energy savings compared to traditional pressure‑maintaining designs, ensuring exceptional efficiency and energy conservation.

Ultra-high-pressure press filter

High feed pressure and large processing capacity: The maximum feed pressure reaches 1.5 MPa, twice that of conventional filter presses, enabling faster feeding and producing filter cakes up to 70 mm thick (actual cake thickness depends on the characteristics of the coal slurry). Taking an 800 m² filter press as an example, a single cycle can be completed in 30 minutes, with a per‑cycle output of up to 25 tons of coal slurry and an hourly production rate of up to 50 tons. The filter plates are made of high‑strength magnesium‑aluminum alloy, featuring a lightweight design that reduces the overall machine weight. They offer excellent mechanical strength, superior toughness, and strong pressure resistance. The service life of the filter plates is 10 years!

Fully automatic rotary filter press with filter cloth

The Shengjing unmanned filter cloth‑traveling plate-and-frame filter press achieves a cake moisture content as low as 60%. Compared with conventional filter presses, which typically yield cakes with 70–80% moisture, this system delivers superior dewatering and greater sludge volume reduction. The resulting sludge cake is thin (1.0–1.3 cm) and free of “soft center” issues; during discharge, the filter plates open in a single step, and the filter cloth automatically unloads the sludge without manual scraping. Each filter plate is equipped with a filter cloth‑cleaning nozzle, enabling multiple online cleaning cycles per day, ensuring consistent moisture levels and production capacity while extending the service life of the filter cloth. For the sludge conditioning stage, only a small dose of PAM and ferric salts is required—no lime is needed, eliminating any additional sludge generation. Sludge discharge is fully automated, obviating the need for gantry‑type cleaning systems, with simultaneous cleaning performed concurrently.
