Sucking Type Auto-washing Filter

This filter has rough and refined two layers of sieve. At the refined sieve, there is a sucking scanner which is running rotary drived by the motor. The discharging valve is installed on the top of the filter cover. When washing, the motor drive the scanner to suck and discharge the impurities. The washing will no need to disrupt the water flow.

BTDX filter can effectively filtrate suspended matters in all medium and high viscosity liquid. It adopts back flush and electronic brush discharging technologies. Filtrating area is large, size is small, structure is compact, filtrate efficiency is high, washing deeply, water consumption is small. It can filtrate and discharge at the same time, not affect and disrupt the system running. It can widely used in petroleum, steel, chemical, machinery, pharmacy, electron, agricultural spray irrigation, municipal construction, minerals, waste water treatment, etc.


Principle
When water flowing into the filter, firstly large particles are filtrated by rough sieve, and then filtrated by fine sieve. The impurities gathered in the inner of fine sieve, so there is a differential pressure between inside and outside of fine sieve. When the pressure is up to 0.04MPa, the switch will signal controller, controller start up the motor to drive the scanner running rotary to sucking and discharging the impurities. It adopt the PLC control, can control the back washing by the differential pressure or timing. It is can washing by manual or choose the constant washing design. When it is fault, there is a alarming signal.


Feature
Compact structure, strengthen and reliable
PLC control, safe and reliable, no need person to operate, running cost is low;
High precision filtration, wide application
Adopt wedge type Ss filter sieve, high impact resistance and stability. It is better than weave sieve. The operation life is long, and the filtrate and back washing function is excellent.
Water consumption for the back washing is small, required water pressure is low. Not affect the water supply when back washing.


Parameter

Water temperature: ≤95℃
Pressure loss: <0.018MPa
Filtering precision: 10-3000um
Self-washing time: 10-60s
Sieve: Stainless steel
