CATHAY Plate and Frame Filter Press Plate and frame extrusion dehydration Filter cake with low moisture content

CATHAY plate and frame filter press: an excellent choice for efficient solid-liquid separation

1. Precision structure lays the foundation for efficient filtration

CATHAY plate and frame filter press adopts modular design, compact and stable structure. The frame is made of high-strength alloy steel, forged and welded by special process, can withstand huge pressure, ensure that the equipment does not deform under high-intensity work, and has a service life of more than 20 years. The filter plate and filter frame are arranged alternately, and the surface of the filter plate is engraved with fine grooves, which not only increases the filtration area, but also guides the filtrate to be discharged quickly, improving the filtration efficiency; the filter frame is made of reinforced polypropylene material, which has excellent acid and alkali resistance and corrosion resistance, and can operate stably even in the face of slurry with complex chemical properties. The filter cloth is a key filtration medium, made of imported high-quality fiber material, with uniform and fine pores, which can accurately intercept tiny particles with a particle size as low as 0.1μm to ensure the clarity of the filtrate.

2. Innovative principle to achieve deep solid-liquid separation

When working, the equipment follows the advanced pressure filtration principle. First, the hydraulic system is started, and the strong pressure pushes the compression plate to fit the filter plate and the filter frame tightly to form sealed filter chambers. Subsequently, the slurry is evenly injected into the filter chamber through the feed port under the pumping pressure. Under the action of the pressure difference, the liquid component penetrates the filter cloth and converges along the filter plate groove to the drain port for discharge, while the solid particles are intercepted by the filter cloth and gradually accumulate in the filter chamber to form a filter cake. When the filter cake reaches a certain thickness and the filtration efficiency begins to decrease, you can choose to start the diaphragm pressing function (equipped with some models), and fill the diaphragm with compressed air or high-pressure water to squeeze the filter cake for the second time to further reduce the moisture content of the filter cake; you can also introduce compressed air to penetrate the filter cake to replace the residual water, achieve deep dehydration, and reduce the moisture content of the filter cake to below 30%.

3. Excellent performance, adaptable to multiple application scenarios

Mining field: In metal ore beneficiation, whether it is the concentration and dehydration of raw ores such as gold, copper, and iron ore, or the tailings treatment link, CATHAY plate and frame filter press performs well. It can efficiently separate solids and liquids in the slurry, recover valuable metal minerals, reduce the water content of tailings, and reduce the footprint of tailings ponds and environmental pollution risks. Taking gold ore dressing as an example, the slurry can be efficiently concentrated to provide slurry of suitable concentration for subsequent cyanide leaching and other processes, thereby increasing the leaching rate of gold.

Chemical industry: For various slurries containing solid impurities produced in chemical production, such as dyes, pigments, pesticide intermediates, etc., the equipment can accurately filter and remove impurities to improve product purity and quality. At the same time, in terms of chemical wastewater treatment, pollutants such as suspended solids and heavy metal ions in the wastewater can be intercepted to achieve standard discharge or reclaimed water reuse.

Environmental protection industry: In urban sewage treatment plants, it is used for sludge dehydration, and the sludge with a water content of up to 95% - 98% is reduced to 60% - 80% after filtration, which greatly reduces the volume of sludge and facilitates subsequent transportation, landfill or incineration. In the treatment of industrial hazardous waste, it can also effectively separate the liquid in hazardous waste, reducing the difficulty and cost of hazardous waste treatment.

Food and pharmaceutical industry: Adopt materials and designs that meet food-grade and pharmaceutical-grade hygiene standards, strictly guarantee the hygiene safety and quality stability of products in the starch dehydration and juice clarification in food processing, as well as the raw material drug filtration and liquid impurity removal in pharmaceutical production, and meet the strict regulations of relevant industries.

4. Intelligent control to improve production management efficiency

CATHAY plate and frame filter press is equipped with an advanced PLC intelligent control system, which monitors the equipment operation status in real time through high-precision sensors, such as pressure, flow, cake thickness and other parameters. Operators can easily set key parameters such as filtration pressure, feed speed, pressing time, etc. on the touch screen in the central control room. The system automatically and accurately controls the equipment operation according to the preset program, realizing one-button start, automatic operation and fault diagnosis. The equipment also supports remote monitoring function. Even if the management personnel are in a different place, they can view the equipment operation data at any time through mobile phones or computer terminals, timely discover and solve potential problems, greatly reduce manual intervention, reduce labor intensity, and improve the accuracy and efficiency of production management.

5. Energy saving and consumption reduction, practice the concept of green development

In the design and manufacturing process, CATHAY fully considers energy saving factors. Optimize the design of the hydraulic system, use high-efficiency and energy-saving oil pumps and motors, accurately match the power requirements of the equipment operation, and reduce energy consumption by 15% - 25% compared with traditional plate and frame filter presses. At the same time, the filter chamber structure and feed path are reasonably planned to reduce the flow resistance of slurry and reduce pumping energy consumption. During the operation of the equipment, the working mode can be flexibly adjusted according to the properties of the slurry and the filtering requirements to further save energy, which is in line with the current industry development trend of green production, energy conservation and emission reduction, and helps enterprises reduce operating costs while helping to achieve sustainable development goals.
