    Automation & Auxiliary Systems for Filter Press

    Automation & Auxiliary Systems for Filter Press

    Integrated Engineering from N.M. Patel & Co.

    At N.M. Patel & Co., we offer a comprehensive range of automation and auxiliary features that significantly improve the performance, reliability, and operational efficiency of our filter press systems. Designed for manual, semi-automatic, and fully automatic presses, these systems are modular, scalable, and tailored to fit every industry — from pharmaceuticals and chemicals to mining, food processing, and wastewater treatment.

    Dual Mode Operation (Auto / Semi-Auto) +

    Our control panels are equipped with a dual-mode selector, enabling seamless transition between automatic and semi-automatic modes based on process needs. This ensures uninterrupted operations during maintenance, process variations, or in energy-saving scenarios.

    Includes:

    • Auto/manual selector switch
    • Logic interlocks and fail-safe system
    • Manual override buttons for safety and flexibility

    Ideal for:

    • Plants with fluctuating loads
    • Operator-preferred manual control setups
    • Troubleshooting and emergency control
    Auto / Semi-Auto Plate Shifter +

    This system allows for the automated shifting of filter plates after each cycle for fast, efficient cake discharge. The semi-automatic version requires minimal operator assistance and is ideal for mid-scale operations.

    Benefits:

  • Reduces physical labor and human error
  • Synchronizes with filtration cycle
  • Minimizes downtime between cycles
  • Safe and smooth shifting along guide rails
  • Optional speed adjustment for different slurry types
  • Automatic Cloth Washing System +

    A high-pressure, automated washing unit that cleans filter cloths in place without disassembly, restoring filtration efficiency and extending cloth life.

    Features:

  • Linear or oscillating spray system
  • Adjustable pressure (3–6 bar)
  • Timer or sensor-based activation
  • Integrated drain tray and splash guard
  • Compatible with PLC and SCADA
  • Drip Tray (Bomb Door Type) +

    The hydraulically/pneumatically operated drip tray opens after filtration to allow cake discharge and closes to collect filtrate during operation, keeping the work area clean.

    Key Features:

  • Constructed from SS 304/316 or coated MS
  • Synchronized with filter press cycles
  • Seals effectively against slurry leakage
  • Reduces corrosion and improves hygiene
  • Optional tilt sensors and limit switches
  • Plate Vibrating System +

    A mounted vibration motor gently shakes the plates post-filtration to help remove sticky or compressible cakes that don't fall off easily.

    Benefits:

  • Reduces manual scraping
  • Prevents filter cloth damage
  • Speeds up cake removal
  • Can be timed or sensor-activated
  • Safety Curtains +

    Installed as physical barriers or photoelectric sensors, safety curtains provide essential protection during press movement or plate shifting.

    Features:

  • Stops all mechanical motion if breached
  • Enhances compliance with industrial safety standards
  • Integrated with emergency stop circuits and alarms
  • Optional motor interlock for extra safety
  • Air / Electric Actuated Valves +

    These valves allow for automated control of slurry, wash water, air, and filtrate lines, ensuring precision flow regulation with zero manual involvement.

    Advantages:

  • Faster and more reliable than manual valves
  • Programmable via PLC for perfect timing
  • Compatible with SS/PTFE-lined bodies for corrosive media
  • Reduces operator fatigue and error
  • Conveyor System +

    Conveyor systems (belt or screw type) automatically transfer discharged filter cakes from below the press to designated bins or disposal areas.

    Benefits:

  • Eliminates manual cake handling
  • Ensures continuous operation
  • Available with variable-speed drives
  • Optional level sensors and auto-start integration
  • Reduces spillage and cleanup effort
  • Filter Cake Breaker +

    Used to break large or compacted filter cakes into smaller, more manageable sizes — essential for dense materials or downstream drying/processing.

    Applications:

  • Sludge, clay, pigment, and mineral cakes
  • Installed below hopper or at conveyor inlet
  • Improves flow to dryers or transport systems
  • Optional enclosure for dust control
  • Hydraulic Automation System +

    The hydraulic power unit (HPU) controls the plate pack movement, drip tray, and other actuators with consistent force and safety.

    Features:

  • Single/double hydraulic cylinder setups
  • Motor and pump assembly with oil reservoir
  • Safety valves, pressure gauges, and limit switches
  • Optional oil cooler for long-duty applications
  • Integrated with control panel for auto commands
  • PLC System with SCADA / Remote Operation +

    Our advanced control systems allow fully automated filter press operation with data logging, cycle monitoring, and remote troubleshooting.

    Capabilities:

  • Touchscreen HMI with multi-language support
  • Remote login for diagnostics and updates
  • SCADA integration for plant-wide control
  • Real-time pressure, flow, and fault monitoring
  • Data logs for quality and compliance tracking
  • Pre-Fabricated Filter Press Platform Structure +

    These steel platforms support the filter press at an elevated height, enabling gravity-assisted cake discharge, space savings, and improved access.

    Features:

  • Modular, bolt-on construction
  • Anti-skid walkways, handrails, and ladders
  • Designed to handle equipment load and vibration
  • Painted or galvanized options available
  • Compatible with sump tanks and conveyors below
  • Header Pipeline with Automatic Valves +

    A compact piping assembly for slurry, filtrate, wash water, and air, equipped with automated valves and flow control.

    Advantages:

  • Centralized and clean layout
  • Reduces leaks and joint fatigue
  • Simplifies operation and maintenance
  • Built from SS 304/316 or chemical-resistant coatings
  • Integrated pressure and flow sensors (optional)
  • Cake Collection Hopper +

    A robust discharge hopper located beneath the filter press, designed to collect filter cake efficiently and direct it to downstream systems like conveyors or bins.

    Features:

  • Sloped design ensures smooth cake flow
  • Vibrator or breaker options to assist discharge
  • Available in SS, MS, or FRP based on media
  • Sized based on press capacity and cake weight
  • Optional chute connection or outlet valve
