The automatic brush filter is composed of the main components such as the driving organization, the control pipeline (including the differential pressure switch), the main assembly, the filter element assembly, the cleaning organization, and the connecting flange. The drive motor and electric valve automatically finish cleaning and discharging sewage. The operation method is automatic work (also manual work), with pressure difference or punctual automatic sewage discharge function.
Its automation part uses the more advanced and reliable PLC programmable controller in the world today. When the water flows through the filter, the mechanical impurities in the water are blocked by the filter. When the impurities accumulated on the surface of the filter increase and the pressure difference reaches 0.04MPa, the differential pressure type differential pressure switch announces the signal, and the PLC announces the instruction and transmission together. Initiated by the motor, the sewage valve is opened, and the impurities deposited in the filter are brushed by the rolling brush and discharged from the sewage outlet. The entire brushing and sewage process requires no human operation and no shutdown. Together, the device also cleans the sewage and manual cleaning on time Sewage function to ensure the safety and reliability of the water under any circumstances.
The automatic brush filter has the functions of filtering raw water and automatically cleaning and draining the filter element, and the system continuously supplies water during cleaning and draining. There are two control methods for automatic brush filter cleaning: automatic control and manual control.
Automatic control: There are two methods of automatic control: punctuality and pressure difference. Set the filter time on the filter time timer. When the filter time is reached, the sewage is initiated. The sewage time is set by the sewage time timer. Together, the control system compares the system pressure difference with the user-set pressure difference in real time. When the system pressure difference reaches the set pressure difference, the filter is also cleaned and drained, and the drain time is set by the drain time timer. When the blowdown time is up, intermittent cleaning is performed, and the system returns to its initial state, preparing for the next filtration process.
Manual control: Turn the manual / automatic selection switch on the operation panel to the manual position, and the filter will discharge the sewage.
Users can choose two control methods according to their needs. For specific operations, see the operation section below.
feature of product.
Filtration accuracy is selectable from 100 to 3000 microns, large filtration area and high dirt holding capacity, users can customize according to practical working conditions.
The cleaning method is simple, and the cleaning cycle is monitored to complete the automatic cleaning and drainage. All parameters in the automatic filter control system can be adjusted.
With motor overload protection, it can effectively protect the motor.
It has the characteristics of uninterrupted water supply and no bypass when cleaning and discharging sewage, and the cleaning time is short, and the water consumption of sewage is less, which does not exceed 1% of the total flow.
Strong repairability, easy installation and disassembly.
The connection method with the user pipeline is flange connection. The flange is selected from the national standard flange, which has strong versatility.
Automatic brush filters are widely used in circulating or non-circulating cooling water systems, heat exchange systems, central air conditioning systems, centralized heating systems, hot water boiler systems, etc., and are used to protect cooling equipment, heat exchange equipment, air conditioners, Boiler, etc. The equipment is suitable for a wide range of occupations, including construction, chemical, power, metallurgy, rubber, paper, light textile, coal, food and other occupations.
