Product Introduction

It is an intermittent filtration device in which filter plates are pressed together to form sealed chambers. Under positive pressure, a filter cloth serves as the filtration medium, allowing the solid-liquid mixture (slurry) to undergo separation within each chamber.

Key Features and Advantages

Simple Structure

Relatively low failure rate and easy maintenance.

Wide Applicability

Suitable for solid-liquid separation of various viscous and fine materials.

High Filtration Pressure

The static seal can withstand high feed pressures, producing relatively dry filter cakes.

Easy Operation

Simple to understand and operate.

Low Cost

Initial purchase cost is lower compared to diaphragm filter presses.

Main Applications

Photovoltaic New Energy Industry

In the purification of photovoltaic materials (such as silicon, quartz sand) and the recovery of cutting fluid, a large amount of wastewater containing fine particulate matter will be produced.
Zhonghao filter press can efficiently achieve solid-liquid separation, recover valuable metal powder and cutting fluid, and the moisture content of the filter cake is low, which is convenient for resource utilization.

Petrochemical Industry

In the petrochemical production process, sludge with complex components containing oil and catalysts will be produced.
Zhonghao filter press adopts special filter cloth and optimized structure, which is corrosion-resistant and has good sealing.
It can efficiently treat such sludge, the filtrate is clear, and the separation is accurate to meet the requirements of environmental protection and discharge.

Food Medicine Industry

In food processing (such as starch, juice, yeast) and pharmaceutical (antibiotics, traditional Chinese medicine extraction, fermentation liquid) processes, there are a large number of links that require precise solid-liquid separation.
Zhonghao filter presses use materials and designs that meet food hygiene standards to ensure quality and safety, efficiently separate and recycle valuable intermediate products or by-products, and ensure the safety and quality of the final product.

Municipal Sewage Industry

Dehydration is a key part of the biochemical sludge produced by municipal sewage treatment plants.
Zhonghao filter press equipment has a high degree of automation and stable operation. It can continuously press the flowing sludge into dry and hard mud cakes, greatly reducing the volume and weight of the sludge, creating favorable conditions for subsequent incineration, composting or landfill disposal, and effectively reducing municipal operating costs.

Tailings Mine Industry

Facing the mud treatment problems caused by tailings, sand washing, etc., Zhonghao filter press has demonstrated excellent dehydration performance.
It can compress ore slurry with extremely high moisture content into a sturdy, low moisture content filter cake, reducing the risk of environmental pollution.

Aquaculture Wastewater Industry

Aquaculture wastewater is rich in nitrogen, phosphorus and organic matter, and direct discharge is extremely harmful.
The Zhonghao filter press function quickly separates the suspended solids and manurefrom the wastewater to form dry manure residue.
These manure residues are high-quality raw materials for making organic fertilizers, which realize the resource utilization of waste.

Frequently Asked Questions

Our popular products include: vehicle-mounted sludge solidification units, diaphragm filter presses, sludge dewatering machines, as well as engineering design and installation services for municipal sludge and sand-washing sludge treatment.

How to choose the right filter press model based on material properties?

Selecting a filter press model depends on key material properties: particle size (to determine filter cloth mesh), viscosity (affects required pressure), corrosiveness (dictates filter plate material, e.g., PP for mild corrosion, stainless steel for strong), and solid content (influences filtration area and cycle time). High-solids materials need larger filtration areas, while abrasive materials require wear-resistant plates. Match pressure ratings to material viscosity—thicker slurries need higher pressure (1.0–2.5 MPa) for effective dewatering.

What to do if filter plates leak?

First, stop operation and check:

Filter cloths: Replace damaged or misaligned cloths that disrupt sealing.
Filter plate seals: Inspect for cracks, wear, or debris; clean seals or replace plates if damaged.
Pressure imbalance: Ensure uniform pressure across plates (adjust hydraulic system if uneven).
Plate alignment: Realign plates if shifted during operation. Test with low pressure after fixes to confirm leaks are resolved.

Do filter cloths need regular replacement? How often?

Yes, filter cloths require regular replacement as they clog, tear, or degrade over time, reducing filtration efficiency. Frequency depends on material: 4–8 weeks for abrasive/viscous materials (e.g., mining slurries); 3–6 months for less harsh materials (e.g., food-grade liquids). Signs to replace early: slower filtration, increased pressure, or visible damage (holes, fraying).

Is installation and operation training provided after purchase?

We offer installation and operation training post-purchase. This typically includes on-site installation guidance, hands-on operation training (e.g., setting parameters, troubleshooting), and documentation (manuals, video tutorials). Some provide follow-up support for 1–3 months to ensure operators master key functions, especially for automated or custom models.

If the power supply is not the issue, how to fix the machine tripping and shutting down?

Check these common causes:

Overload: Motor may be overworked (e.g., excessive slurry feed); reduce load or inspect for jammed components (e.g., filter plate movement).
Faulty sensors: Pressure or temperature sensors may trigger safety shutdowns; calibrate or replace malfunctioning sensors.
Hydraulic system issues: Low oil level or clogged filters can cause pressure spikes; check fluid levels and clean/replace filters.
Electrical connections: Loose wires in control panels may interrupt power; tighten connections and inspect for short circuits.
