Boost Capacity.
HDLY Automatic Vertical Press Filter incorporates technologies from domestic and international press filters. It is widely used for solid-liquid separation through washing, filtering, and dewatering processes across multiple industries including non-ferrous metals, smelting, chemical processing, coal beneficiation, food production, porcelain manufacturing, paper production, sugar refining, dye processing and wastewater treatment.
Lower Moisture Content in Filter Cake
Max. pressure 1.6 MPa with Min. moisture content ≤ 10%
6X
Capacity vs. Plate-and-Frame Filter Press (Same Filtration Area)
All six working processes operate automatically and continuously, delivering over 6 times the production capacity per unit area compared to frame filter presses.
Compact Structure
The four-column vertical design requires minimal floor space, enabling facility upgrades with reduced or zero additional plant investment.
Self-Cleaning Filter Cloth
The filter cloth features alternating washing on both surfaces with excellent cleaning results. Its horizontal placement ensures uniform cake thickness up to 45mm.
Advanced Automation
The system operates fully automatically via control panel, equipped with self-diagnostic and automatic alarm functions.
From Slurry to Dry Cake
Fully Automated.
The main processes of HDLY Automatic Vertical Press Filter include: feed-in, diaphragm squeeze, washing (optional), and air drying.
4 Stages
Short Process
Filtering → Squeeze → Drying → Discharging (Excludes washing steps)
6 Stages
Complete Process
Filtering → 1st Squeeze → Washing → 2nd Squeeze → Drying → Discharging
Filtering
Filtering
When the frame assemblies close, slurry flows through the feed pipe into each filter chamber. The filtrate penetrates the filter cloth into the filtrate chamber, then passes through the flexible filtrate tube before being discharged via the filtrate header.
Squeeze I
Squeeze I
High-pressure water is pumped through the flexible pipe to the top of the diaphragm, applying squeezing pressure. This forms the filter cake between the diaphragm and cloth while forcing the filtrate out of the cake.
Cake Washing
Cake Washing
Wash liquid is pumped into the filter chamber through the same manifold pipe used for slurry. As the chamber fills completely with wash liquid, the diaphragm lifts to expel the high-pressure water above it. The wash liquid then flows through the filter cake and cloth before exiting via the discharge pipe.
Squeeze II
Squeeze II
Any remaining wash liquid in the chamber after washing is expelled using the same method as the first squeeze.
Air Drying
Air Drying
Compressed air is introduced into the filter chamber through the manifold pipe, filling the chamber and raising the diaphragm before being discharged. The air passing through the cake reduces the moisture content to the optimal level and also empties the filtrate chamber.
Discharging
Discharging
After the drying process is complete, the frame assemblies open, and the cloth drive units start operating. The filter cake on the cloth is then discharged from both ends of the filter.
