Intelligent Protective Program-Controlled Filter Press

Intelligent Protective Programmable Control Filter Press

The Intelligent Protective Programmable Control Filter Press is an advanced solid-liquid separation device that integrates intelligent control technology and protective functions. Below is a detailed introduction:

Features

Intelligent Control: It uses advanced control systems such as Programmable Logic Controllers (PLC) to fully automate the filtration process, including feeding, filtration, squeezing, and discharging. It also enables remote monitoring and operation with real-time parameter adjustments.

Precise Pressure Control: Equipped with high-precision pressure sensors and advanced hydraulic or pneumatic systems, it can precisely control filtration and squeezing pressures. This ensures a stable and suitable pressure environment based on different materials and process requirements, guaranteeing filtration efficiency and filter cake quality.

Intelligent Fault Diagnosis and Alarm: The system has a self-diagnosis function that continuously monitors the equipment's operating status. In case of abnormal conditions, such as pressure deviations, motor overloads, or filter cloth damage, it immediately issues an audible and visual alarm and automatically takes protective measures.

Superior Protective Performance: Designed for special applications like the electronics industry, the equipment is built with various protective features. For instance, electrical components are sealed to prevent dust, moisture, and other contaminants from entering, enhancing the equipment's safety and stability.

Data Recording and Analysis: The system automatically records parameters and data such as pressure, flow rate, filtration time, and filter cake thickness during the filtration process. This data is stored and analyzed to help optimize production processes, improve efficiency, reduce costs, and ensure quality traceability and management.

Working Principle

Filtration Stage: The liquid containing solid particles is fed into the filtration chamber, which consists of filter plates and filter cloth, by the feed pump. Under pressure, the liquid passes through the filter cloth, while solid particles are retained on the filter cloth's surface. As filtration progresses, the solid particles accumulate and form the filter cake.

Squeezing Stage: Once the filter cake reaches a certain thickness and filtration resistance increases, slowing the filtration speed, compressed air or high-pressure liquid is introduced into the diaphragm to further squeeze the filter cake, expelling more liquid and improving the filter cake's dryness.

Discharge Stage: After the filtration and squeezing processes are completed, the filter plates are loosened, and the automatic plate pull system opens the plates. The filter cake then falls off the filter cloth, either by gravity or with the assistance of a discharge device, completing the discharge process.

Application Fields

Electronics Industry: Used for filtering electronic slurry, electroplating wastewater, cleaning liquids, etc., effectively capturing micron and even nano-sized particles, ensuring the high purity of electronic materials and meeting the stringent product quality requirements of the electronics industry.

Chemical Industry: Widely used in the production of various chemical raw materials and products, such as dyes, pigments, resins, and rubber, for solid-liquid separation, improving product quality and production efficiency.

Environmental Protection Industry: Used in sewage treatment plants, industrial wastewater treatment stations, etc., to process sludge and wastewater, achieve solid-liquid separation, and recycle water resources, reducing environmental pollution.

Food and Beverage Industry: Used in the production of juices, beverages, alcoholic drinks, etc., to separate solid particles such as pulp and impurities, improving the clarity and quality of the final products.
