An automatic backwash filter is an advanced, efficient, and easy-to-operate automatic filter that is used to intercept impurities in the water to purify water quality or protect the normal operation of other equipment in the system.
Brief Description
An automatic backwash self cleaning filter is an indispensable treatment method in the process of water purification, which is used to intercept impurities in the water to purify water quality or protect the normal operation of other equipment in the system.
An automatic backwash filter is an advanced, efficient, and easy-to-operate automatic filter. The filter is composed of a tank body, stainless steel filter screen, sewage part, transmission device, and electrical control part.
Auto backwash filter working principle and process:
1. The reduction motor drives the flushing arm to rotate through the intermediate shaft to align it with the cleaned filter screen;
2. Open the blowdown valve to make the pressure difference between the outside of the cleaned filter screen (clean side) and the blowdown;
3. Under the action of pressure difference, the liquid flow at the cleaning side flows from the outside to the inside of the cleaned filter screen for backwashing, and the pollutants accumulated on the inside of the filter screen are washed away and discharged from the filter through the drain outlet;
4. The backwash time of each filter screen has been set. When the backwash time is reached, the blowdown valve is closed, the backwash process of the filter screen is completed, the reduction motor drives the backwash arm to rotate again, the next filter screen is backwashed, the blowdown valve is opened again, and so on to backwash each filter screen;
5. After all filters are cleaned, the flushing arm returns to the original position under the control of the photoelectric switch, and a backflushing cycle ends;
6. Since backwashing is the flushing process of a group of filter screens, the filter can still maintain the continuous filtering state of liquid flow during backwashing.

Advantages of automatic backwash filter：
1. The automatic backwash filter has the characteristics of a simple structure and easy disassembly.
2. Directly installed on the pipe network system, without any support structure, saving space.
3. The investment cost is saved. In the installation process, there is no need to use multiple bypass pipelines, which reduces the labor intensity and avoids the removal and drainage during the adjustment test and maintenance.
4. Flexible installation, horizontal installation, and vertical installation.
5. Resistance of filter at rated flow rate is 0.05~0.1m water column.
6. The filter screen cylinder is fixedly connected to the pipe body as a whole, with rigidity, good strength, no wearing parts and long service life.
7. Specification of filter screen:10 mesh/inch,14 mesh/inch,20 mesh/inch, can also be customized according to user requirements.
8. When the backwash filter is cleaned and drained, the uninterrupted water supply of the system, high automation degree, large treatment capacity, self-cleaning, and drainage
Application of automatic backwash filter
It is widely used in the fields of metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electric power, and urban water supply.
Such as industrial wastewater, filtration of circulating water, regeneration of emulsion, waste oil filtration treatment, continuous casting water system in the metallurgical industry, high furnace water systems, and high-pressure water descaling systems for hot rolling.
