Export area:North America Central-South America ASIA Europe Africa Oceania

Introduction:
NYLON MONOFILAMENT MESH
Also operating on the principle of surface filtration, monofilament mesh filter bags are manufactured from mesh materials in which each strand is a single filament.The non-deformable filaments are woven in a specific, consistent pattern and fusion welded for extra strength. Monofilament meshes are structurally very strong and are available in nylon (STANDARD).
Our felt bags are designed to withstand higher solid loading, and are suitable for applications using vessel or open filtration systems. With FQ filter bags, you can count on a quality product every time.
We makes its own fiber to produce the felt material used in our felt filter bags inhouse, guaranteeing the highest quality.

Automatic back wash filter housing

Introduction:
Automatic Back Wash Filtration System
Working principle
The Flow Direction:
(1)The liquid enters from N2 at the bottom of the cylinder into the filter, passing through the fixed cartridge, the liquid exit from N1 at the center of the filter from outside toward inside. Backwash pollutants discharged from N3.
2)Liquid flow from the cartridge medial (pollution side) to the lateral(clean side), solid particles are trapped in the filter inside, with the increase of pollutants, the differential pressure between the pollution side and the clean side gradually increases. When the pressure reachs the pre-determined value (the value can be empirical value or debugging value ) , the filter automatically start the backwash process.
Filtration process:
* The speed reducer drives the washing arm by the middle connecting shaft. The washing arm rotational angle is controled by the infrared correlation orientation to align with the filter cartridge.
* The sewage valve is open and creates pressure difference between the lateral(clean side) and the outlet.
* Under the pressure difference, the clean lateral liquid flow from outside to inside and begin the backwashing. Filter pollutants cumulate at the inner part are cleaned and discharged from N3 outlet.
* The backwashing time of the cartridge can be adjusted automatically according to process variations. When the time is up, the sewage valve will close down and the cartridge backwash will end. The gear motor rotates the washing arm to start the backwash of the next cartridge, opening the sewage valve again, this process is repeated until all the cartridges are backwashed.
* The whole backwash term has N-1 groups (N is the number of cartridges). As a term is over, the washing arm stays on the position of N-1and waits for the next term backwash.
* Since the filter backwash process is done in a group,during the backwash process, the filter is in a continuous state of filtration.

Introduction:
Plastic bag filter housing is a filtration system which is produce with 100% PP (polypropylene )úČtaking advantages of excellent PP material, can be used for filtering a lot of chemical sour soda liquids. It is really an economical and practical fine product, as it has no seam, no dead angle, accurate specification with high-quality, high capacity and efficiency.
---The inner-side is very smooth, no ditch, no dead angle, easy to wash;
---P- handle on the cover helps to open the top cover and change materials;
---2"-4" FLANGE Inlet and Outlet;
---The bag has a grip respectively, very convenient to change, safe and clean;
---Working pressure can reach 7kg/cm2 (design pressure 15kg/cm2), operate temperature can be up to 43 íŠ/ 110F (material able to bear 83 íŠ);
---Please operate in accordance with the condition of standardizing , make sure not to exceed pressure limit or temperature limit.

basket strainer

Export area:North America Central-South America ASIA Europe Africa

Introduction:
Basket strainer is the necessary equipment on the pipeline, as the safe-guard filter, removes large contaminant particles and protect key equipments such as pumps, nozzles, heat exchangers and valves. It can obviously extend the service life of key equipments, improve operational efficiency and avoid the risk of costly system downtime. SF filter also works well as the direct large particle filter. The metal filter basket is reusable by cleaning and cost less filter media consumption.

Self cleaning filter housing

Model:

Export area:North America Central-South America ASIA Europe Africa

Introduction:
The scraping self-cleaning filter, automatically removes particles from the filter element surface by the efficiently mechanical scraping, can work on-line continuously, consumes no disposal filter media, requires no frequent manual cleaning, is capable of the filtration for both normal and high viscous liquids.

The scraping self-cleaning filter has 3 sub-series: A series, the pneumatic cylinder drives the scraper up and down to remove the particles on the filter element internal surface, good at the normal viscous liquid and high filtration degree application, has the highest cleaning efficiency; X series, the motor drives the scraper to rotate and remove the particles on the filter element external surface; M series, the motor drives the scraper to rotate and remove the particles on the filter element internal surface; the X series and M series are good for the high viscous liquid.

The conventional manual filter gets frequently clogged when filtering viscous liquid or removing viscous contaminant. so that customer has to accept the larger filter and clean the filter frequently. It takes expensive investment, requires hard maintenance and discharges lot of waste liquid. The scraping self-cleaning filter is the ideal solution for such problems, always keep the filter element cleaning, and discharges the liquid with high solid content and result in less valuable liquid loss. With its obvious advantage, The scraping self-cleaning filter is taking the places of conventional ones such as the vibrating screens, bag filters, basket filters and some back-flushing filters, etc...
