China Manufacturer of Chamber Filter Press

SINOU Chamber Filter Press is a mature batch-type pressure separation equipment independently developed for industrial solid-liquid separation. Different from traditional plate-and-frame structures, it adopts integrated recessed filter plates to form sealed filter chambers directly, removing redundant filter frames. This optimized design delivers better tightness, larger effective filtration area and higher operational stability.

Designed for heavy-duty 24-hour intermittent operation, this chamber filter press is widely deployed to dewater various sludge, slurry and suspended solids. It can separate solid particles and liquid efficiently, producing dry filter cakes and reusable filtrate. It is a mainstream choice for wastewater treatment, mining tailings disposal, chemical production, concrete batching plants and many other industrial scenarios.

Our products have been exported to Europe, the Middle East, Southeast Asia and other regions, winning recognition for stable performance and competitive cost performance.

Working Principle & Complete Process Flow

This chamber filter press operates based on mechanical pressure filtration. The whole workflow is fully automated and divided into 5 standard stages:

1. Slurry Feeding: Driven by the feeding pump, raw slurry is delivered to each sealed recessed filter chamber through the central feeding port until full filling.

2. High-pressure Filtration: The hydraulic system pushes filter plates to compress tightly. Under continuous pressure, liquid penetrates filter cloth and flows out as clean filtrate, while solid particles are trapped inside chambers to form filter cakes.

3. Pressure Holding: The system maintains stable pressure for a certain period to further reduce cake moisture and ensure thorough solid-liquid separation.

4. Automatic Cake Discharge: Hydraulic pressure is released, filter plates are pulled open one by one by the plate pulling mechanism, and dry filter cakes fall off automatically.

5. Cloth Cleaning & Reset: The built-in high-pressure cleaning device rinses residual sludge on filter cloth. The equipment resets to standby for the next cycle.

The hydraulic pipeline is well sealed to eliminate oil leakage, with low noise and low failure rate during operation.

(5) Automatic Plate Pulling Mechanism

Driven by precision motor and transmission parts. It pulls filter plates flexibly without jamming, realizing fully automatic cake unloading. An optional auxiliary vibration device is available for sticky sludge to ensure complete cake discharge.

(6) Intelligent Control System

PLC + HMI integrated control cabinet is equipped as standard. It supports one-key automatic cycle and manual mode switching. The touch screen displays real-time pressure, running status and historical data.

Built-in overload, overpressure and leakage protection functions guarantee equipment and operator safety.

(7) Automatic High-pressure Cleaning System

Standard high-pressure water flushing unit. It cleans filter cloth thoroughly after each working cycle, removing attached sludge and fine particles, so as to maintain long-term stable filtration efficiency.

Core Technical Advantages

(1) Excellent Sealing Performance: Recessed plate integrated structure avoids material leakage, solving the common run-off problem of traditional plate-and-frame filter presses.

(2) High Filtration Capacity: Larger effective filtration area and optimized flow channels improve overall throughput, suitable for large-volume slurry treatment.

(3) Strong Working Adaptability: Resists acid, alkali, abrasion and high temperature, running stably in various complex industrial environments.

(4) High Automation Level: The whole process is unattended, greatly cutting labor costs and daily management work.

(5) Low Comprehensive Operation Cost: Simple structure, fewer vulnerable parts and convenient maintenance reduce long-term operating expenses.

(6) Eco-friendly & Resource-recyclable: Separated filtrate can be reused; dry filter cakes are easy for transportation and harmless disposal, complying with global environmental regulations.

Professional FAQ

Q1: What is the biggest difference between chamber filter press and plate-and-frame filter press?

A: The core difference lies in the structure. The chamber type uses integrated recessed filter plates to form chambers without filter frames, featuring better sealing, higher efficiency and easier automation. The plate-and-frame type relies on combined plates and frames, which is prone to leakage and more suitable for small-batch production.

Q2: Can this equipment handle fine particle sludge such as desert sand?

A: Yes. We adopt targeted high-density filter cloth, which can effectively intercept fine particles. Matched with the front-end stirring system, it avoids sludge deposition and ensures stable long-term operation.

Q3: Can the separated filtrate be recycled for production?

A: Absolutely. The filtrate after pressure filtration is clear and free of visible solid particles. It can be directly reused for production water, wastewater circulation and other procedures.

Q4: Is the filter cloth easy to be blocked?

A: Equipped with an automatic high-pressure cleaning system. The filter cloth is fully rinsed after each cycle, which effectively removes attached sludge and prevents clogging. We also provide different filter cloth options for various materials.

Q5: Can the equipment adapt to 380V 60Hz power supply for Gulf regions?

A: Yes. We support global mainstream power standards (50Hz/60Hz). Electrical components are optimized for generator power supply to adapt to on-site power conditions in the Middle East and other regions.

Q6: Is customized service available for special working conditions?

A: We support full customization including filtration area, filter plate size, overall dimension and power parameters to meet personalized site demands.
