Function and purpose: 

 ZQX series brush apply to the wastewater treatment process self-cleaning filter, steel plant slag water, power plant process and cooling water, papermaking processes and water, chemical production processes and irrigation systems and other occasions, for the filtered water 3500-80 micron particle size of the hard particles, to ensure safe and reliable operation of the system. 

 Device structure and working principle: 

 ZQX Series Brush Johonson filter self-cleaning filter device using high-intensity, with a handling capacity, long life and high efficiency cleaning. This machine adopts pressure control, timing control of the self-cleaning filters. When the filter pressure drop reaches the set time, issued by the electric control box signal drive motor rotation, while the drain valve open. Particles of impurities adsorbed on the Internet even rotating wire brush with water from the sewage discharge valve. When the filter pressure drop recovery after the end of the normal or timer setting time, the motor stops running, the electric drain valve is closed. Throughout the process, the material flow, to achieve a continuous, automated production. 

 Installation and use: 

 The ZQX type magnetic brush type filter can be horizontal or vertical installation, the installation should pay attention to the direction of the arrow on the housing must be consistent with the direction of flow, and the direction of flow when mounted vertically requirements following from the last, when the import and export pressure difference of 0.04 MPa, the need to open the drain valve, gently turn the handle artificial sewage, until the discharge water quality is clear, close the drain valve, the system can be normal, with no downtime.
