Automatic self-cleaning brush filter for boiler water system

 
Describe

The automatic self-cleaning filter is highly efficient and automatically backwashed. It can realize online automatic cleaning, automatic sewage discharge function, operation with three functions of differential pressure/timing/manual, and provide stable water quality guarantee for your water system. The filter continues to run during the flushing process, and a small amount of water is used during the flushing process, which makes the filter very efficient.

Working principle

[Filtering status]
The liquid flows in from the inlet, and the strip-shaped scraper is close to the surface of the filter element. The liquid flows outward from the surface of the filter element through the filter. The impurities are trapped on the inner surface, and the liquid flows out from the outlet; as time goes by, the impurities gradually When the pressure increases, the pressure difference rises, and the filter screen is cleaned according to the set pressure difference or regularly.
[Cleaning status]
The motor drives the wiper to clean the filter screen in a horizontal rotation motion. When the wiper rotates, the impurities are removed by the brush and flow to the bottom of the filter. Each cleaning consists of several strokes. After the surface of the filter is cleaned, the filtering capacity is restored. Normally filter during cleaning, and the flow will not be interrupted.
[Sewage status]
After multiple cleaning cycles, impurities accumulate to a certain amount, and the drain valve is opened regularly to discharge the waste liquid containing high-concentration impurities. If necessary, it can also be recycled.

Features

1. Fully automatic operation, continuous online filtering, ending the heavy filter replacement and cleaning work;
2. The filtration pressure loss is small, the flow rate is stable, and energy saving is conducive to the continuous stability of the entire process;
3. Sealed and filtered to prevent leakage of filtered liquid, which is conducive to safe production and employee health;
4. The discharged waste liquid with high impurity concentration can be recycled to reduce the loss of high-value materials;
5. A variety of advanced control systems are optional, powerful, efficient and reliable;
6. Use world-renowned brand components with high reliability and low cost.
