High-performance industrial general-purpose automatic hydraulic box-type filter press, ensuring stable and reliable solid-liquid separation
1. Robust frame structure:
It is made by welding high-quality steel and has undergone stress relief treatment. This ensures that the frame has extremely high mechanical strength and stability, capable of withstanding repeated high-pressure working loads without deformation or cracking.
2. Efficient hydraulic pressing system:
The integrated hydraulic station operates smoothly with low noise.
Provide continuous, stable and powerful clamping force to ensure that the filter plate assembly remains tightly sealed during the filtration process, with no leakage.
Equipped with a hydraulic protection device, it will automatically release pressure when the pressure exceeds the set value, protecting the core components of the equipment.
3. High-quality box-type filter plates:
The filter plate is precisely cast from reinforced polypropylene (PP) or other materials as per the working conditions. It is corrosion-resistant, resistant to acids and alkalis, lightweight, and of high strength.
The surface of the filter plate is smooth and flat, with a well-designed flow channel to ensure smooth material feeding, uniform distribution of the filter cake, and smooth discharge.
4. Reliable automatic pressure retention function:
During the filtration process, the hydraulic system can automatically compensate for the slight relaxation caused by pressure loss, maintaining the required sealing pressure of the filter chamber at all times, ensuring the stability and safety of the filtration process.
1. Strong processing ability:
Suitable for solid-liquid separation of various materials. It has excellent filtration effects on granular and suspended materials, and the solid content in the filter cake is high.
2. Stable and reliable operation:
The core hydraulic and filtration system technologies are mature, with low failure rates. They can adapt to harsh industrial environments and ensure the continuity of production.
3. Simple maintenance:
The modular design makes it easy to inspect and replace major components such as the hydraulic station and filter plates. The filter cloth is simple to disassemble and install, and easy to clean. The daily maintenance workload is small.
4. Energy conservation and environmental protection:
The efficient solid-liquid separation effectively reduces pollutant emissions. The filtrate is clear and can be recycled or discharged in compliance with environmental standards, meeting environmental protection requirements.
1. Pressing down the filter plates: Start the hydraulic system. The piston rod pushes the pressing plate, causing all the filter plates to be pressed tightly between the thrust plate and the pressing plate, forming individual sealed filter chambers.
2. Feed filtration: The feed pump pumps the suspended liquid to be filtered into the filter press. The material enters each filter chamber through the feed holes on the thrust plate. Under the pressure of the pump, the filtrate passes through the filter cloth and flows out of the machine through the drainage holes on the filter plate, while the solid particles are retained in the filter chamber and gradually form a filter cake.
3. Release the filter plate: After the process is completed, the hydraulic system releases the pressure and the piston rod moves the clamping plate back to its original position.
4. Removing the filter cake: Pull out the filter plates. Due to its own weight, the filter cake falls off from the filter cloth and drops into the collection tank below, completing one working cycle.
This model is widely used in industrial fields where solid-liquid separation of suspensions is required, mainly including:
Chemical industry: Filtration of dyes, pigments, pigment intermediates, white carbon black, ceramic glazes, boric acid, soda ash, etc.
Metallurgical mining: Dewatering of metal concentrates and tailings such as lead-zinc ore, copper ore, gold ore, and bauxite.
Environmental protection industry: Dewatering treatment of sludge from urban sewage plants, sludge from industrial wastewater treatment, and sludge from river dredging.
Food industry: Clarification and filtration of saccharifying enzymes, starch, fruit juice, plant extracts, etc.
Coal industry: Dewatering and recovery of pulverized coal, flotation clean coal, and tailings.
Other fields: Refining and recovery of products such as oils, catalysts, and fillers.
