✅ Energy-Saving & Eco-Friendly – Low power consumption, clear filtrate for recycling, reduced wastewater load.
1. Basic Structure The plate and frame filter press is mainly composed of the following components:
Filter Plates: The surface is equipped with grooves, which support the filter cloth and form the filtration chamber.
Filter Frames: Located between the filter plates, they provide space for accommodating the filter cake.
Filter cloth: Covers the filter plate and functions as the filtering medium.
Hydraulic System: Provides pressure to ensure that the filter plates and filter frames are tightly pressed together.
Feed Pump: This pump is used to convey the suspended liquid (slurry) to be filtered into the filtration chamber.
2. Working Process (1) Clamping Stage The hydraulic system drives the clamping plate, causing the filter plate, filter frame and filter cloth to closely adhere to each other, forming a sealed filtration unit.
(2) Feed Filtration (Filtration Stage) The feed pump pumps the slurry into the filter box. Under the action of pressure: The liquid (filtrate) passes through the filter cloth and flows out along the grooves of the filter plate. Solid particles (filter cake) are retained within the filter frame and gradually accumulate.
(3) Cake Formation As the filtration process continues, the solid particles within the filter frame accumulate continuously, forming a certain thickness of filter cake until the entire filter frame space is filled.
(4) Discharge Phase (Cake Discharge) After filtration is completed: The hydraulic system releases the clamping plate, causing the filter plate and the filter frame to separate. The filter cake falls off due to gravity or the automatic scraper device, completing the solid-liquid separation.
(5) Cleaning (Optional) Some models support automatic cleaning of the filter cloth, ensuring higher filtration efficiency in the next run.
