Stainless steel plate-and-frame filter press with 304/316L/PP multi-material filter plates; high-pressure filtration with optional diaphragm pressing; solid-liquid separation equipment for traditional Chinese medicine, pharmaceuticals, chemicals, and food industries; custom filtration area available.
Description
Product Overview
A stainless steel plate-and-frame filter is a batch-type filter press consisting of alternately arranged filter plates and frames, with filter cloth sandwiched between them. It features a large filtration area and low filter cake moisture content, making it suitable for the batch production of suspensions with high solids content.
How It Works
Under pump pressure (0.3–0.6 MPa), the feed solution enters each filter frame through the feed channel; solids are retained by the filter cloth to form a filter cake, while the filtrate passes through the filter cloth and flows through the grooves in the filter plates to the outlet. After filtration is complete, loosen the clamping plate to remove the filter cake.
Main Structural Components
Frame (stainless steel or carbon steel cladding)
Filter Plates + Filter Frames (304/316L/Polypropylene)
Clamping device (manual lead screw, hydraulic, or electric)
Feed Pump (Screw Pump or Diaphragm Pump)
Filter cloth (polypropylene, polyester, nylon)
Drip tray or flap
Core Strengths
Large filtration area: A single unit can cover an area of 100 m² or more.
Low moisture content in the filter cake: A diaphragm press can be used to further dewater the material.
High-voltage resistant: The filter plates can withstand pressures of 1.0 MPa or higher.
A variety of materials: Metal plate-and-frame filters are resistant to high temperatures and solvents; PP plate-and-frame filters are corrosion-resistant and lightweight.
Washable: Feed the washing solution through the filter cake to perform displacement washing.
Typical Use Cases
Extraction of Traditional Chinese Medicine: Removal of carbon residue from the activated carbon decolorization solution after alcohol precipitation.
Fine Chemicals: Solid-liquid separation after crystallization of dyes, pigments, and intermediates.
Pharmaceuticals: Filtration and washing of active pharmaceutical ingredient crystals.
Food: Filtration of citric acid, monosodium glutamate, and yeast.
Mine: Concentrate dewatering.
