JCI AFE Automatic Self Cleaning Filter

Product Description

AFE Self cleaning filter  is mainly designed for high-viscosity and soft impurities filtration, with the precision range being ***1,**0μm. Featuring precise filtration can effectively remove impurities from the surface of filtering screens, thus removing more impurities with high efficiency. It applies to the filtration of water and various viscous liquids. AFE Strainer designed and manufactured as per Shanghai JCI's standards for high performance, high quality and high reliability, it features internationally first-class quality.

 Traditional filters easily get blocked when used to filtrating viscous materials and soft impurities. For this reason, large-sized filters are usually selected or manual cleaning is frequently conducted, resulting in heavy investment, heavy work and serious waste of materials. Such problems can be easily solved by AFE Strainer with advanced self-cleaning mode. It can regularly maintain cleanness of filtering screens and expel waste fluid containing high-concentration impurities, thus reducing waste of materials. It has evident advantages and higher efficiency in filtrating poor-quality water and viscous materials such as adhesive, resin, polymer, coatings and grease. AFE Strainer with notable technical advantages and low operation costs, it has gradually displaced the traditional manual filters in various fields, such as vibrating screeners, bag filters, basket filters, etc.

How Does It Work?
Filtering status(see figure 1)
 Liquid flows inside from the inlet.The liquid flows inward from the outer surface of the filter screen, and the impurity is intercepted on the outer surface. Then, the liquid flows out from the outlet; with the passage of time, the impurities gradually increase, and differential pressure rises. We can begin to clean the filter screen according to the preset differential pressure or the timing.

Cleaning status(see figure 2)
 The motor drives the scraper to rotate horizontally to clean the filter screen. When the scraper rotates, impurities are scraped off and filtered along the filter net to the bottom of the filter, and the impurities with large specific gravity are deposited into the dirty collector. Each cleaning is made up of a number of strokes. After the filter screen is cleaned, the filtering ability is restored. No filtration interruption while self-cleaning.

Discharging status(see figure 3)
 After a number of cleaning cycles, impurities accumulate to a certain amount. Regular opening of drain valve, and the waste liquid containing high concentration of impurities is discharged. which can also be recycled, if necessary.

Technical features and advantages
 1. Horizontal rotary scraping, scraping off the impurities directly, is good at filtering viscous liquids and removal of viscous, soft and suspended impurities;
 2. Simple structure, easy dismounting; after removing the scraper, easy to take out the filter screen, and easy to clean the inside;
 3. Automatic operation, continuous online filtration, to end up the heavy filter screen replacement and cleaning work;
 4. Do not produce disposable filter material, saving consumables costs and environmental costs;
 5. Small filtration pressure loss, stable flow rate, energy saving is beneficial to the continuous stability of the whole process;
 6. Sealed filtration, preventing dangerous material leakage, is advantageous to the safe production and the staff health;
 7. Discharge waste liquid with high impurities concentration can be recycled, to reduce the loss of high-value materials;
 8. A variety of advanced control systems are optional, powerful, efficient and reliable;
 9. Selection of world-renowned brands of components, high reliability, low costs.

Automatic Cleaning Control System
AFE Self cleaning filter is equipped with automated cleaning control system, integrated differential pressure cleaning and timing cleaning parallel control function, which controls its efficient working, according to the operating conditions. If necessary, the system is able to realize real- time and remote monitoring of DCS by custom. Differential pressure cleaning is the most efficient cleaning mode, which reflects the accumulation of of filter cakes and the blocking of the filter element. When the preset pressure differential is reached, it starts the self-cleaning action. It is suggested that the cleaning pressure differential is 0.1MPa, which can be adjusted within the scope of 0.***0.1MPa, by the working conditions. Periodically cleaning can be set ***4 hours, and if the differential mode is inefficient, time pattern still works. It can be considered as the ultimate protection. The cleaning period setting should be close to the average period of the filter pressure differential cleaning mode.
 The automated differential pressure controller has two kinds of forms, differential pressure switch and differential pressure transmitter. The transmitter can output the real time pressure differential value with higher sensitivity and reliability, to facilitate long-distance and real-time monitoring of the DCS
