New amine,alcohol, phenol, ether Self-Cleaning Filter

AFC series syringe type pneumatic self-cleaning filter (abbreviated as AFC filter) is a new scraper-type self-cleaning filter with independent intellectual property rights of Shanghai Jiucheng Company. It can automatically remove particulate impurities on the inner surface of the filter through mechanical scraping. Continuous online filtration. The AFC filter is mainly designed for high-viscosity filtration. It is suitable for high-viscosity liquid filtration. The accuracy range is 30-1500 microns. The filter can quickly scrape impurities off the surface of the filter screen, thereby effectively removing more impurities. It is suitable for water and various Filtration of viscous liquids. The AFC filter is 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 self-cleaning method of AFC filter can easily solve this kind of problem, keep the filter screen clean regularly, and discharge waste liquid with high concentration of impurities, reduce material waste, filter poor water quality water and adhesives, resins, polymers, coatings, grease, etc. Obvious advantages for viscous materials and higher efficiency. With its significant technical advantages and low operating costs, AFC filters are gradually replacing 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. There are 4 sub-series, AFE series, motor-driven outer scraper, AFC series, cylinder driven inner scraper, and AFM series motor driven inner scraper, which are suitable for Different working conditions can meet customers' various mechanical self-cleaning filtration requirements (see the introduction of AFE&AFM&AFB for details).

Product Details

[Filtering status]

The liquid flows in from the inlet. The spring-mounted disc-shaped scraper is close to the inner surface of the filter element and stops at the end of the filter. The liquid passes through the scraper and flows outward from the inner surface of the filter. The impurities are trapped on the inner surface, and the liquid flows from the outlet. Outflow; as time goes by, the impurities gradually increase and the pressure difference rises, and the filter screen is cleaned according to the set pressure difference or regularly.

【Cleaning state】

The air cylinder drives the scraper to reciprocate up and down to clean the filter screen. When the scraper moves down, the impurities are pushed to the bottom of the filter by the scraper, and the impurities with large specific gravity settle into the dirt collection chamber. When the scraper moves upwards, the remaining impurities are scraped and pushed to the upper end of the filter element. The impurities are washed away by the flowing liquid, pass through the scraper, and return to the inner surface of the filter screen. When the scraper moves downwards, it is scraped away. Each cleaning consists of several strokes. After the surface of the filter is cleaned, the filtering capacity is restored. Normally filter during cleaning without interruption of flow. 

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

AFC 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 filter cake on the inner surface of the filter or the clogging of the filter. When the set pressure difference is reached, the self-cleaning action is started. Cleaning is recommended The differential pressure value is 0.1Mpa and 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 types of differential pressure transmitters for automatic control systems. The transmitter can output real-time differential pressure values, with high sensitivity and reliability, and is convenient for DCS remote real-time monitoring.

1. Up and down reciprocating scraping, directly push impurities to the dirt collection chamber, good at filtering viscous liquids and removing viscous suspended impurities.

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

3. Fully automatic operation, continuous online filtration, and stop the heavy filter element 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.

8. A variety of control systems are optional, powerful, high-energy operation, high reliability.

9. Optional components, high reliability, low operating cost.
