China Supplier of 870 Hydraulic Filter Press for Gold Tailing, Coal Washing & Metallurgy
I. Main Structure and Characteristics
1. Rack Section:
- Tail plate (thrust plate): Fixed end, connected to the foundation.
- Head plate (compression plate): The movable end is driven by a hydraulic cylinder to achieve the compression and release of the filter plate.
- Main beam: Usually made of high-strength steel as a double beam, it bears the weight of all the filter plates and filter cakes, and requires good rigidity and high strength.
2. Filtering Section:
- Filter plate: The material is usually reinforced polypropylene (PP), which features light weight, corrosion resistance, and high strength. The filter plate has a concave middle section, which is used to collect the filtrate and support the filter cloth.
- Filter cloth: Based on the characteristics of the filtered material (such as particle size, acidity and alkalinity), different materials (such as polyester, polypropylene, nylon) and weaving methods are selected for the filter cloth. This is a key consumable component that determines the filtering effect.
- (Optional) Diaphragm compression filter plate: A filter plate with an elastic rubber diaphragm. After the feed is completed, high-pressure medium (water or gas) can be introduced to perform secondary pressing on the filter cake, significantly reducing the moisture content of the filter cake.
3. Hydraulic System:
- It is composed of an electric motor, a hydraulic pump, a hydraulic cylinder, a hydraulic valve and an oil tank.
- Provide stable and powerful clamping force to ensure no material is sprayed during the filtration process.
- The electrical contact pressure gauge automatically maintains pressure and automatically replenishes pressure when the pressure drops. It is safe and reliable in operation.
4. Automatic Plate Pulling System (Optional):
- The puller plate device is driven by a motor, chain or hydraulic motor. It automatically and sequentially pulls out the filter plates, replacing the cumbersome manual operation and achieving automation, thereby improving efficiency.
5. Electrical Control System:
- Using PLC (Programmable Logic Controller) and touch screens, the entire filtration process is automatically controlled.
- Parameters such as compression pressure, holding time and pulling plate speed can be set and adjusted.
- It has fault alarm and emergency stop functions, and is easy to operate with high safety and reliability.
II. Summary of Product Advantages
- High dehydration efficiency: Utilizes high-pressure feed and optional diaphragm pressing, resulting in low moisture content in the filter cake.
- Large processing capacity: The filtration area is wide-ranging, capable of meeting the production demands of different scales.
- Low operating cost: The structure is sturdy, and the lifespan of components such as filter plates is long; the automation level is high, reducing the need for manual labor.
- Simple operation and maintenance: PLC control, one-click operation; filter cloth replacement is convenient.
- Excellent stability: The hydraulic system has a strong and stable clamping force, ensuring that no material is sprayed during the filtration process and guaranteeing reliable operation.
- Environmental protection and energy conservation: Achieve effective separation of solid and liquid substances, and the filtrate is clear and can be reused, meeting environmental protection standards.
III. Main Application Fields
- Environmental Protection Industry: Dewatering treatment of sludge from urban sewage plants, and industrial wastewater (such as from dyeing, papermaking, electroplating, and food processing).
- Mining and Metallurgy: Metal tailings (such as lead-zinc ore, bauxite), mineral concentrate dehydration, and smelting sludge treatment.
- Chemical Industry: Solid-liquid separation for products such as pigments, dyes, fertilizers, resins, and salt sludge.
- Ceramics and Building Materials: Dewatering of raw materials such as ceramic slurry, quartz sand, kaolin, etc.
- Food: Filtration during the production of ingredients such as starch, fruit juice, and yeast.
