The plate-and-frame filter press is a common solid-liquid separation equipment, widely used in industries such as mining, chemical, food, and pharmaceuticals. Its main function is to separate solid-containing liquids through physical methods to obtain clear liquids and filter cakes.
Product Features
Simple structure: Composed of filter frames, filter plates, support frames, and a hydraulic system, it is easy to operate and maintain.
High efficiency: Capable of achieving efficient solid-liquid separation in a relatively short time.
Adjustable pressure: The pressure can be adjusted through the hydraulic system to meet different process requirements.
Strong durability: Made of corrosion-resistant materials, suitable for the treatment of various media.
Applications
Mining: Used for the concentration of ores and the dewatering of tailings.
Chemical industry: Suitable for the filtration and separation of chemical products.
Food industry: Plays a role in the clarification treatment process of liquids such as fruit juices and oils.
Pharmaceutical industry: Used for the separation of solids and liquids in drug production.
Wastewater treatment: Widely applied in the processes of sludge dewatering and wastewater treatment.
Work Principle
The plate-and-frame filter press pumps the liquid containing solid particles into the filter chamber, applies pressure using the hydraulic system, causing the liquid to pass through the filter cloth, and the solid particles are left between the filter plates to form a filter cake. After the filtration is completed, the filter cake is discharged mechanically, completing the entire separation process.
Maintenance and Care
Regular inspection: Check the integrity of filter plates, filter cloths, and seals to ensure normal operation of the equipment.
Cleaning: Wash the filter cloths and plates promptly after use to prevent blockages and cross-contamination.
Lubrication: Regularly lubricate the hydraulic system and moving parts to maintain smooth operation of the equipment.
Summary
With its efficient solid-liquid separation capabilities and simple operation process, the plate-and-frame filter press has become an indispensable piece of equipment in various industries. Proper use and maintenance will significantly enhance its work efficiency and extend its service life.
