SCFM series electric internal scraping type self-cleaning filter (referred to as SCFM scraper filter) is a new type of scraper type self-cleaning filter, which can automatically remove the particles and impurities on the inner surface of the filter screen by mechanical scraping, and can continuously filter online. SCFM scraper filter is mainly designed for high-viscosity filtration, suitable for filtration of high-viscosity liquids, with an accuracy range of 30-1500 microns, accurate filtration, and can quickly scrape impurities off the surface of the filter screen, thereby removing more impurities, suitable for water and various Filtration of viscous liquids.

 

SCFE series electric external scraping type self-cleaning filter (referred to as SCFE scraper filter) is a new type of high-energy scraper type self-cleaning filter. Impurities can be continuously filtered online. Traditional filters are frequently cleaned manually, with large investment, heavy work and serious material waste. SCFE electric external scraping filter can easily solve such problems with advanced self-cleaning method, always keep the filter screen clean, and discharge waste liquid with high concentration of impurities, reduce material waste, filter poor water quality and adhesives, resins , polymer, paint, grease and other viscous materials have obvious advantages and higher efficiency. 
SCFB electric scraping brush self-cleaning filter (referred to as SCFB brush self-cleaning filter) is a new type of high-energy self-cleaning filter, which can automatically clean the particulate impurities on the inner surface of the filter element by mechanical means, and can continuously filter online. The SCFB brush type self-cleaning filter can quickly clean the impurities from the surface of the filter screen, thereby effectively removing more impurities, and is suitable for the filtration of water and various low-viscosity liquids.

SCFC series pneumatic self-cleaning filter (referred to as SCFC pneumatic filter) automatically cleans the particles and impurities on the inner surface of the filter screen by mechanical scraping, and can continuously filter on-line. SCFC pneumatic filter is mainly designed for high-viscosity filtration, suitable for high-viscosity liquid filtration work, the accuracy range is 30-1500 microns, accurate filtration, can quickly scrape impurities off the surface of the filter screen, thereby effectively removing more impurities, suitable for water and Filtration of various viscous liquids. 
SCFM、SCFE、SCFB、SCFC all are designed and manufactured in accordance with the standards of high performance, high quality and high reliability, reaching international high quality
Traditional filters are frequently blocked when filtering viscous materials and soft impurities. Only large-scale filters or frequent manual cleaning can be selected. The investment is large, the work is heavy, and the material waste is serious. SCFM scraper filter can easily solve such problems with advanced self-cleaning method, always keep the filter screen clean regularly, and discharge waste liquid with high concentration of impurities, reduce material waste, filter water with poor water quality and adhesives, resins, polymers , paint, grease and other viscous materials have obvious advantages and higher efficiency. SCFM scraper filter is gradually replacing traditional manual filters such as vibrating screen, bag filter, basket filter, etc. in many fields with its obvious technical advantages and low operating costs.
working principle
[ Filter Status ]
The liquid flows in from the inlet, the scraper with compensation is close to the inner surface of the filter screen, the liquid flows outward from the inner surface of the filter element through the filter screen, the impurities are trapped on the inner surface, and the liquid flows out from the outlet; with the passage of time, the impurities gradually If the pressure increases, 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 rotate horizontally to clean the filter screen. When the scraper rotates, the impurities are scraped off by the scraper and flow to the bottom of the filter screen, and the large proportion of impurities are deposited in the sewage collection chamber. Each cleaning consists of several strokes, and after the surface of the filter screen is cleaned, the filtering capacity is restored. Normal filtration during cleaning, flow is not interrupted.
[ Pollution status ]
After several cleaning cycles, the impurities accumulate to a certain amount, and the drain valve is opened regularly to discharge the waste liquid containing high concentration impurities, which can also be recycled if necessary.

Technical features and advantages

■Horizontal rotary scraping, directly scraping away impurities, good at filtering viscous liquids, removing viscous soft and suspended impurities;
■ Simple structure, easy to disassemble and assemble, after removing the scraper, the filter screen can be easily taken out, and the interior is easy to clean;
■ Fully automatic operation, continuous online filtration, ending the heavy filter replacement and cleaning work;
■ No disposable filter consumables are produced, saving the cost of consumables and environmental protection;
■ The filtration pressure loss is extremely small, the flow is stable, the energy consumption is saved, and the process is continuous and stable;
■ Airtight filtration to prevent leakage of dangerous materials, which is beneficial to production and employee health;
■ The discharge waste liquid has high impurity concentration and can be recycled to reduce the loss of high-value materials;
■ A variety of control systems are optional, with powerful functions, high-energy operation and high reliability;
■ Select components from world famous brands, high reliability and low operating cost.
 

Automatic cleaning control system

The SCFM filter is equipped with an automatic cleaning control system, which integrates the parallel control functions of differential pressure cleaning and timing cleaning, and can control the high-energy operation of the filter according to the working conditions. If required, remote real-time monitoring of DCMF can also be realized by customization. Differential pressure cleaning is suitable for most occasions and is a good cleaning mode. The pressure difference reflects the accumulation of filter cake on the surface of the filter element or the blockage of the filter element. When the set pressure difference value is reached, the self-cleaning action is started. It is recommended to clean the pressure. The difference is 0.1MPa, which can be adjusted within the range of 0.01-0.1MPa according to the working conditions. The 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 a 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 in automatic control system, differential pressure switch and differential pressure transmitter. The transmitter can output real-time differential pressure value, with higher sensitivity and reliability, which is convenient for DCMF remote real-time monitoring.
