What benefits can you bring to your business by choosing a vacuum belt filter?-Xinxiang Yinuo Machineries Co., Ltd.

What is vacuum belt filter？

Vacuum belt filter as an advanced solid-liquid separation device, the core of its operation relies on the strong power generated by the vacuum negative pressure, with the help of the continuous circulation of the annular filter belt to achieve the goal of solid-liquid separation.

Working Principle

The material is spread evenly on the filter belt, when the belt starts to move, the material will enter the vacuum adsorption area in sequence. In this area, with the help of negative vacuum pressure, the liquid in the material is quickly extracted, while the solid particles are retained on the filter belt, gradually accumulating to form a cake. As the filter belt continues to move forward, the final cake will be automatically stripped from the filter belt, so that the completion of a complete continuous separation process.

Horizontal belt filter skillfully integrates vacuum adsorption technology, mechanical transportation technology and automation control technology and other advanced technologies. Compared with the traditional intermittent filtration equipment, it has significant advantages in filtration efficiency, ease of operation and degree of automation, etc. It is an ideal and efficient alternative to the traditional intermittent filtration equipment.

The use of vacuum belt filter, in the end, where is good?

Compared with plate and frame filter, centrifugal filter and other traditional equipment, its advantages are reflected in the multi-maintenance, direct eh to solve the enterprise production of many pain points.

Advantage dimension	Embody	Advantages compared to traditional equipment (such as plate and frame filters)
Continuous operation efficiency	Operating continuously for 24 hours without frequent start-ups and shutdowns, with stable processing capacity (single unit processing capacity up to 1-50m³/h)	The plate and frame need to be frequently assembled and disassembled, the cake needs to be unloaded, and it operates intermittently, resulting in an efficiency of only 60%-70%
Degree of automation	Automatic feeding, filter cloth cleaning, and filter cake stripping require only 1-2 people for monitoring, reducing manual intervention	The plate and frame require manual loading and unloading of the plates, which is labor-intensive and susceptible to human error
Material adaptability	It is suitable for processing materials ranging from 0.1μm to 5mm in particle size, such as ore pulp, sludge, and crystalline substances, at concentrations of 5% to 60%	Centrifugal filters are prone to clogging with high-viscosity materials, and plate and frame filters have poor retention performance for fine particles
Filter cake dryness	Vacuum adsorption combined with filter belt squeezing can reduce the moisture content of the filter cake to as low as 15%-30% (depending on the material), thereby reducing subsequent drying costs	The moisture content of the plate and frame filter cake is usually 30%-50%, requiring additional drying in the subsequent process, which increases energy consumption by 20% or more
Environmental protection and energy conservation	The recovery rate of filtrate is over 95%, and the filter cloth can be cleaned and reused. The discharge of wastewater and waste residue is reduced by 30%-50%	Traditionalequipmentexperienceshighfiltratelossandrequiresfrequentreplacementoffiltercloth,whichcaneasilyleadtosecondarypollution

Applications

With wide applicability, Horizontal vacuum belt filter occupies an indispensable position in many industries, especially suitable for those scenarios that need to process materials in large quantities and require continuous production:

Mining

Treating gold and copper tailing slurry, separating the moisture of iron and zinc concentrates in order to reduce transportation costs.

Chemical industry

separating crystallized materials such as potassium nitrate, recycling mother liquor of pesticide production.

Environmental protection

Municipal life, printing and dyeing sludge and garbage leachate residue dewatering.

Food

Starch production separation of starch milk, juice filtration and dregs removal, sugar plant separation of molasses and sugar residue.

Pharmaceuticals

Filtration and purification of traditional Chinese medicine extract, separation of antibiotic fermentation liquid according to GMP standards.

Building materials

Filtration of glaze in ceramic factories, separation of gypsum production and waste liquid of gypsum dihydrate.

These industries have high requirements for separation efficiency and environmental protection, and the Horizontal belt filter can precisely meet these requirements.

It is the urgent need for enterprise development and continuous technological progress that makes the vacuum belt filter widely used. Here we look at what the use of vacuum belt filter can bring to the enterprise.

Cost reduction and efficiency

now the rising cost of workers, enterprises naturally prefer automated equipment, with the ability to run continuously, reduce the loss due to downtime.

Environmental standards

At present, the emission control of wastewater and waste residue is becoming more and more strict, and the traditional equipment is often difficult to meet the standards, while the vacuum belt filter, with its excellent filtrate recycling and low-emission characteristics, can effectively help the enterprise to avoid environmental protection fines.

the material is complex and variable

in the current industrial production, the material composition is increasingly complex, the traditional equipment is often unable to cope with complex materials, while the vacuum belt filter with its wide adaptability, can easily handle most of the materials.

Automatic production

Horizontal vacuum filter can be seamlessly connected with PLC system and MES system to realize remote monitoring and data tracing, which perfectly meets the needs of modern production.

Summary:

The essence of vacuum belt filter is to solve the traditional solid-liquid separation equipment with low efficiency, high cost and poor adaptability through the technical characteristics of “continuous + automation + high adaptability”. In the industrial production of efficiency and compliance requirements are increasingly high today, its scope of application will continue to expand.
