Electronics Industry Filter Press

Features:

High Precision Filtration: The electronics industry requires extremely high product quality. The specialized filter press can achieve high-precision filtration, effectively trapping micron- or even nano-level particulate impurities. This ensures the high purity of liquids such as electronic materials, electroplating solutions, and cleaning fluids, meeting the production needs of the electronics industry.

Strong Corrosion Resistance: The production processes in the electronics industry often involve the use of strong acids, strong bases, and other corrosive chemicals. The filter plates, filter frames, and other components in contact with materials in the specialized filter press are made from corrosion-resistant materials like PTFE (polytetrafluoroethylene) and PP (polypropylene), which can withstand chemical erosion, ensuring the stable operation and long service life of the equipment.

High Degree of Automation: Equipped with an advanced automation control system, the filter press can automatically perform a series of operations, such as feeding, filtration, squeezing, discharging, and cleaning. This reduces manual intervention, improves production efficiency, stabilizes product quality, lowers labor costs, and reduces labor intensity. It also helps avoid quality risks caused by improper manual operation.

Precise Pressure Control: The filter press is capable of accurately controlling filtration and squeezing pressures. Based on different process requirements and material characteristics, it provides a stable and suitable pressure environment, ensuring optimal filtration effects and filter cake quality. This contributes to improved production efficiency and stable product quality.

High Hygiene Requirements: The equipment’s surface is smooth, with no sanitary dead zones, making it easy to clean and disinfect. It meets the high cleanliness standards required in the electronics industry, preventing the growth of impurities and microorganisms, and avoiding contamination of electronic components and products.

Working Principle:

First, pressure is applied through a hydraulic system or other power devices to tightly compress the filter plates, forming a sealed filtration chamber. The liquid containing solid particles, such as electronic slurry or electroplating wastewater, is pumped into the filter chamber by the feed pump.

Under pressure, the liquid passes through the filter cloth, while the solid particles are trapped on the surface of the filter cloth. As filtration progresses, the solid particles accumulate on the cloth, forming a filter cake and achieving solid-liquid separation.

When the filter cake reaches a certain thickness and the filtration resistance increases, causing a slowdown in filtration speed, the filter cake can be further squeezed by the squeezing device to expel more liquid, increasing the dryness of the filter cake.

Finally, once the filtration and squeezing processes are complete, the filter plates are loosened, and through the automatic plate pulling system, the plates are separated. The filter cake falls off the filter cloth due to its own gravity or with the help of a discharging device, completing the discharge process.
