Product Details

Fully automatic self-cleaning filter equipment

Introduction:
It is a precision equipment that uses a filter screen to directly intercept impurities in water, purify water quality, and protect other equipment in the system from normal operation. Water enters the self-cleaning filter body through the inlet, and due to intelligent (PLC, PAC) design, the system can automatically identify the degree of impurity deposition and send a signal to the discharge valve for automatic discharge. To overcome the many shortcomings of traditional filtration products, such as small pollutant holding capacity, susceptibility to blockage by pollutants, the need to disassemble and clean the filtering part, and the inability to monitor the status of the filter, a specific function is to filter raw water and automatically clean the filter element for sewage discharge. The system continuously supplies water during cleaning and sewage discharge, which can monitor the working status of the filter and has a high degree of automation.
Features:

The bottom of the fully automatic self-cleaning filter is equipped with a centrifugal disc, which can generate vortices in the water flow, forming centrifugal force. This can keep solid particles away from the filter disc and gather at the top of the filter, reducing the frequency of filter cleaning.

2. During backwashing, the four water spray columns in the center of the filter element spray water in a tangential direction, striking the disc and causing it to rotate. This creates centrifugal force on the dirt adhering to the disc, making it easier to clean and reducing cleaning time.

3. The shell is made of ABS or nylon engineering plastic, which is resistant to acid and alkali corrosion and has strong impact resistance.

4. The diameter of the disc is relatively large, and the same number of discs corresponds to a larger filtering area of the filter, thereby increasing the filtering capacity.

5. The internal structure of the filter conforms to hydraulic characteristics and has a streamlined structure, which can reduce water head loss and energy consumption.

6. The overall molding and processing technology of the filter shell avoids various drips caused by welding steel filter shells; High strength ductile iron material has excellent anti-corrosion performance, which extends the service life of the product;

7. Exclusive filter design and manufacturing technology, high-precision filter does not wear out;

8. Reliable intelligent control, automatic operation of filtration, cleaning, and sewage discharge, achieving unmanned supervision and uninterrupted water supply;

9. Product structure and functional design, compact structure, large filtration area, high pollutant holding capacity, low pipeline pressure loss, and low power consumption;

10. Optimized control method design, short backwash time, low water consumption for sewage discharge, and water resource conservation;

Fully automatic self-cleaning filter equipment

Working Principle:
（1） Water enters through the inlet, first passing through a coarse mesh to filter out larger particles of impurities, and then reaching a fine mesh. During the filtration process, the fine filter gradually accumulates dirt and impurities in the water, forming a filter impurity layer. As the impurity layer accumulates on the inside of the fine filter, a pressure difference is formed on the inner and outer sides of the fine filter.
When the pressure difference of the filter reaches the preset value, the automatic cleaning process will begin, during which the clean water supply continues to flow. The cleaning valve opens, and the water pressure in the cleaning chamber and the suction pipe drops significantly. Through the pressure difference between the filter cartridge and the suction pipe, a suction force is generated between the suction pipe and the cleaning chamber through the suction nozzle, forming a suction process. At the same time, the electric motor drives the suction pipe to spiral along the axial direction. The combination of axial and rotational motion of the suction device cleans the entire inner surface of the filter screen. The entire flushing process only takes a few tens of seconds. The drain valve is closed at the end of cleaning. The filter is preparing for the next flushing cycle.
（2） The water to be treated enters the body through the inlet, and impurities in the water deposit on the stainless steel filter screen, resulting in a pressure difference. By monitoring the pressure difference between the inlet and outlet through a differential pressure switch, when the pressure difference reaches the set value, the reactor sends signals to the hydraulic control valve and the driving motor, triggering the following actions: the motor drives the brush to rotate, cleaning the filter element, and at the same time, the control valve opens for drainage. The entire cleaning process only lasts for a few tens of seconds. When the cleaning is completed, the control valve is closed, the motor stops rotating, and the system returns to its initial state to enter the next filtering process.
After installation, the equipment is debugged by technicians to set the filtration time and cleaning conversion time. The water to be treated enters the body through the inlet, and the filter starts to work normally. When the preset cleaning time is reached, the electronic controller sends signals to the hydraulic control valve and the driving motor, triggering the following actions: the motor drives the brush to rotate, cleaning the filter element, and at the same time, the control valve opens for sewage discharge. The entire cleaning process only lasts for a few tens of seconds. When the cleaning is completed, the control valve is closed, the motor stops rotating, and the system returns to its initial state, starting the next filtration process.
