With the industry4.0The wave is advancing, and the plate and frame pressure filtration technology is undergoing a revolutionary transformation. This article will focus on cutting-edge technological innovation and analyze its breakthroughs in key industries, providing a technological roadmap for industrial upgrading.

Materials Science: Breakthrough in Filter Plate Performance

The pain points of traditional cast iron filter plates being bulky and perishable are being overcome by new materials:

-Polymer composite materials

Made of glass fiber reinforced polypropylene, with a hardness of65A(Exceeding international standards)9%）Improved tear resistance strength15%In120Extended lifespan under high temperature and strong acid environment of ℃3More than double.

-Flexible diaphragm technology

Composite elastic diaphragm on the surface of the filter plate, introduced during the pressing stage3MPaCompressed air expands the diaphragm and compresses the filter cake twice. Adjust the moisture content from82%drop to75%Below, energy-saving37.5%.

-Nano coated filter cloth

By using vapor deposition technology to construct alumina nano layers on polyester base fabric, the following can be achieved:

-Pore accuracy reaches1Mmlevel

-Contact angle>150The superhydrophobic properties of °

-Chemical tolerance enhancement5times

The cleaning cycle starts from each shift1Extended to weekly1time

Intelligent upgrade: The Internet of Things reshapes the operation and maintenance mode

1. Industrial Internet platform

The new generation of devices integrates multiple types of sensors:

-Real time monitoring of filter chamber pressure distribution by pressure sensor

-Turbidity analyzer online analysis of filtrate quality

-Vibration probe predicts bearing failure

After uploading the data to the cloud,AIAlgorithm automatically optimizes feed pressure and cycle time to increase production capacity18%.

2. Remote unmanned operation

passPLCandSCADASystem integration to achieve:

-mobile phoneAPPRemote start stop device

-Automatic fault diagnosis and push repair plan

-Intelligent adjustment of medication dosage (medication cost as low as0.83yuan/Ton of mud

After being applied by a certain sand and gravel enterprise, labor costs have been reduced70%Annual maintenance fee200Ten thousand yuan.

Energy saving technology: cost control

1. Secondary compression of compressed air

Add airflow penetration after traditional filtration:

- 0.8MPaCompressed air continuously penetrates20minute

-The moisture content of the filter cake decreases again8-10Percentage point

-The energy consumption is only for thermal drying1/10.

2. Intelligent dosing system

Based on online detection of sludge concentration and dynamic adjustment:

-The amount of flocculant added has been reduced to one ten thousandth of the dry mud content

-Optimizing floc structure through charge neutralization effect

-The cost of pharmaceuticals in a certain mining enterprise5yuan/Ton of mud reduced to0.83Yuan.

Industry application depth

Mining sludge dewatering

Develop high-pressure dewatering scheme for iron ore tailings slurry:

-adopt25MPaSqueezing pressure

-The moisture content of the produced filter cake is ≤18%

-Directly resourceful brick making

The investment payback period is only1.2Year.

Food and beverage filtration

Specialized technology for beer wort filtration:

-Food grade polypropylene filter plate

-The oxidation rate of wort is controlled within0.02ppm(Traditional equipment)0.08ppm）

-Improved filtering speed30%

Assist enterprises in obtaining EU food safety certification.

Chemical hazardous waste treatment

Resin residue separation scheme:

-Teflon coated filter cloth resists organic solvent corrosion

-Hazardous waste reduction60%

-Filtration reuse rate>95%

Annual savings on hazardous waste disposal fees300Ten thousand yuan.
