AFE series automatic scraper type self-cleaning filter (referred to as AFE filter) is a new type of scraper self-cleaning filter with independent intellectual property rights of Shanghai Jiucheng Company. The AFE filter automatically removes the outer surface of the filter by mechanical scraping. The impurities can be continuously filtered online. AFE filter is mainly designed for high-viscosity filtration. It is suitable for high-viscosity liquid filtration conditions, ranging from 50-1500 microns. It can effectively peel impurities off the surface of the filter screen, thereby removing impurities more effectively. It is suitable for filtering water and various viscous liquids. AFE filters are designed and manufactured in accordance with Shanghai Jiucheng's high-performance, high-quality, and high-reliability standards to achieve high quality.

Traditional filters frequently clog customers when filtering viscous materials and soft impurities. They can only choose large filters or frequent manual cleaning, which requires large investment, heavy work, and serious material waste. The AFE filter can easily solve these problems by self-cleaning. It keeps the filter screen clean regularly and discharges waste liquid with high concentration of impurities to reduce material waste and filter poor water quality water and adhesives, resins, polymers, paints, and greases. Obvious advantages and higher efficiency when waiting for viscous materials. With its significant technical advantages and low operating costs, AFE filters have gradually replaced traditional manual filters such as vibrating screens, bag filters, basket filters, etc. in many fields.


Shanghai Jiucheng Company has a full series of scraper-type self-cleaning filter products, a total of 4 sub-series, AFE series, motor-driven outer scraper, AFC series cylinder driven inner scraper, AFM series motor driven inner scraper, AFB series motor driven The scraper type is suitable for different working conditions to meet the customer's various mechanical self-cleaning filtration requirements (see the introduction for AFC&AFM&AFB for details).

[Filter status]

The liquid flows in from the inlet, and the scraper with compensation is attached to the outer surface of the filter in a tangential manner. The liquid flows inward from the outer surface of the filter through the filter, the impurities are trapped on the outer surface, and the liquid flows out from the outlet; as time goes by, the impurities Gradually increase, the pressure difference rises, and the filter screen is cleaned according to the set pressure difference or regularly.

[Cleaning state]

The motor drives the scraper to perform a horizontal rotation to clean the filter screen. When the scraper rotates, the impurities are scraped (peeled off) by the scraper and flow along the filter screen to the bottom of the filter, and the impurities are deposited in the dirt collection chamber. Each cleaning consists of several strokes. After the surface of the filter screen is cleaned, the filtering capacity is restored. Normally filter during cleaning without interruption of flow.

[Sewage state]

After multiple cleaning cycles, the impurities have accumulated to a sufficient amount, and the drain valve is opened regularly to discharge the waste liquid with high concentration of impurities. If necessary, it can also be recycled.


Automatic cleaning control system

The AFE filter is equipped with an automatic cleaning control system, which integrates the parallel control function of differential pressure cleaning and timing cleaning, which can control the high-energy operation of the filter according to the working conditions. If necessary, DCS remote real-time monitoring can also be realized after customization. Differential pressure cleaning is suitable for most occasions and is an effective cleaning mode. The differential pressure reflects the accumulation of the filter cake on the surface of the filter element or the clogging of the filter screen. When the set pressure difference is reached, the self-cleaning action is started. The cleaning pressure is recommended. The difference is 0.1MPa, which can be adjusted within the range of 0.01-0.1MPa according to the working conditions. Timed cleaning can be set between 0-24 hours. For example, when the differential pressure mode fails, the time mode still works and can be used as terminal safety protection. The cleaning cycle setting should be close to the average cycle of the filter differential pressure cleaning mode. There are two forms of differential pressure transmitter for automatic control system, differential pressure switch and differential pressure transmitter. The transmitter can output real-time differential pressure value, with high sensitivity and reliability, which is convenient for DCS remote real-time monitoring.

1. Horizontal rotary scraping, scraping away impurities directly, good at filtering viscous liquids, removing viscous soft and suspended impurities.

2. Simple structure, easy to disassemble and assemble, after removing the scraper, the filter screen can be easily taken out, and the inside is easy to clean.

3. Fully automatic operation, continuous online filtration, and stop the heavy filter replacement and cleaning work.

4. No disposable filtering consumables are generated, saving consumables costs and environmental protection costs.

5. The filtration pressure loss is extremely small, the flow rate is stable, energy consumption is saved, and the process is continuous and stable.

6. Airtight filtration to prevent leakage of hazardous materials, which is beneficial to safe production and employee health.

7. The discharged waste liquid has a high impurity concentration and can be recycled, reducing the loss of high-value materials.
