Automatic Suction Brush Cleaning Filters to Remove Suspended Solids
Model No.: YL-X-80
A series of heavy duty filters with automatic cleaning, designed for filtrates with high content of suspended solids and high flow rates. When a differential pressure is sensed the cleaning cycle is initiated and two stainless steel brushes remove debris from the filter screen. The debris is then flushed out the exhaust, using less than 1% of the total flow and without interrupting output. Filtration degrees between 200-3500 micron and flow rates of up to 7200 m3/s can be achieved. Higher flow rates can be achieved by banking multiple units.
The cleaning process
During filtration water flows though the cylindrical screen of the strainer from the inside out. Debris collected on the inner surface of the screen form a "filter cake" that causes a pressure drop across the screen. When this pressure differential reaches a preset value, it is detected by the filter control system and the self-cleaning process automatically starts.
A specially designed exhaust valve, opens and the drive unit starts to rotate two stainless steel brushes which sweep the inner surface of the cylindrical screen. The particles trapped on the screen are dislodged by the revolving brushes and flushed out through the open exhaust valve. Service flow of filtered water is uninterrupted throughout the approximate 20 seconds cleaning process. At the end of the self-cleaning process the motor stops and the exhaust valve closes. The filter control system continues to monitor the differential pressure and when needed starts a new self-cleaning cycle. automatic brush filters are useful mostly for heavy duty, heavy dirt load and coarse filtration applications ranging from 3500 to 200 micron.
Automatic Brush Filter the original water filtration and automatic filter cleaning discharge function, and cleaning sewage system uninterrupted water supply. Automatic Brush Filter cleaning has two control modes: Automatic control and manual control.
Automatic control: Automatic control timing and pressure difference. In the filtering time timer is set on the filtration time, when the filtering time, start the sewage, discharge time from emission time timer setting. At the same time control system real time system and the pressure difference of the user set pressure difference comparison, when the system pressure reaches the set pressure, Also for cleaning sewage filter, pollution by sewage time timer. Arrive at discharge sewage time, stop washing, the system is restored to its initial state, following is the preparing for the next process.
Manual control: Will the operation panel on the automatic / manual selection switch to manual position, filter for sewage.
The user can choose according to the two control mode, specific operations, see behind the operation part.
The circulated or non-circulated cooling water system, heat exchange system, central air conditioning system and central heating system in the industries like architecture, chemistry, metallurgy, rubber, paper making, light textile, coal and foods, used to protect the cooling equipment, heat exchange device and air conditioner accordingly.
