Self cleaning filter bypass filter for steel mills

Product Introduction:

Self cleaning water filter is a widely used equipment in the water treatment industry. Its design is simple and efficient, and it can automatically clean and discharge the filter element while maintaining uninterrupted water supply to the system. The main components of this filter include the motor, electric control box, control pipeline, main pipe component, filter element component, stainless steel brush, frame component, transmission shaft, inlet and outlet connecting flanges, etc. The self-cleaning filter is designed with intelligence (PLC, PAC) to automatically identify the degree of impurity deposition and achieve automatic full discharge by sending a signal to the discharge valve. Its working principle is based on mechanical filtration and backwashing technology. When the impurities accumulated on the surface of the filter element reach a certain level, an automatic cleaning program will be triggered. The filter element will be cleaned by opening the drain valve and the motor to drive the brush to rotate, while also discharging. The entire cleaning process only takes a few tens of seconds, and the system's water supply is uninterrupted.

Characteristics of self-cleaning water filter products:

The product features of self-cleaning water filters mainly include uninterrupted water supply, high filtration accuracy, large filtration area, reliable cleaning method, economical and simple installation, long service life, low comprehensive cost, and simple and efficient operation. These characteristics make self-cleaning water filters have significant advantages in application.

2. Uninterrupted water supply: During cleaning, the self-cleaning filter can maintain a very small amount of water, only 5% of the filter volume, and the flushing time is usually 2-15 seconds, thus maintaining uninterrupted water supply throughout the entire process.

3. High filtration accuracy: The self-cleaning filter can achieve a filtration accuracy of 20 microns, and users can choose different precision filters according to their needs to meet various water quality treatment needs.

4. Large filtration area: The effective filtration area of the filter screen is usually 7-40 times the inlet area, which can handle a large amount of water flow and improve treatment efficiency.

5. Reliable cleaning method: The self-cleaning filter has multiple control methods, including manual, differential pressure, time, PLC program logic control, etc., to ensure the reliability of the cleaning process.

6. Economical and simple installation: The self-cleaning filter has various structural forms, adapts to various installation situations, does not affect the operating effect, and the installation process is economical and simple.

7. Long service life: The filter screen is made of stainless steel material and can last for more than 10 years. Different specifications of filters can be easily replaced according to needs.

8. Low comprehensive cost: Self cleaning filters do not require frequent disassembly and replacement of filter screens, reducing maintenance costs.

Simple and efficient operation: The self-cleaning filter does not require a bypass or disassembly for cleaning during operation, and has good filtration backwash effect, improving work efficiency.

Principle Overview:

When water enters the interior of the filter cartridge from the inlet, impurities are intercepted on the inner wall of the filter cartridge, and the filtered clean water flows out from the outlet. When the impurities accumulate on the inner wall of the filter cartridge, the pressure difference between the inlet and outlet of the self-cleaning filter reaches the preset value, reaches the cleaning time, or is manually prefabricated, the filter will start the self-cleaning process. The entire self-cleaning process includes two steps: opening the automatic drain valve located on the self-cleaning filter; The motor drives the cleaning brush inside the filter screen, and the impurities intercepted by the filter screen are discharged from the discharge valve. The system does not cut off flow during cleaning, and the entire operation process of the self-cleaning filter is controlled by an intelligent control box randomly equipped. Control methods include pressure difference, time, manual, and PLC control. The vertical self-cleaning filter can achieve automatic cleaning, automatic discharge and other functions online. It is equipped with three functions: differential pressure/time/manual. It has the advantages of high filtration accuracy, short cleaning time, less cleaning water, and small pressure loss.

Manufacturing process:

Leading product structure and functional design, compact structure, and unique integrated molding and processing technology for filter shells, avoiding various leaks caused by welding steel filter shells;

2. High strength ductile iron material has excellent anti-corrosion performance, which extends the service life of the product;

3. Exclusive filter design and manufacturing technology, high-precision filter never wears out, pressure inspection never deforms, and factory precision testing meets user requirements;

4. Both coarse and fine filter screens are made of stainless steel welded mesh, and the sieve plate and mesh screen form an inner and outer double-layer structure; Due to the active cleaning method used for the filter element, its anti-interference ability has been enhanced, and the cleaning is thorough, making it particularly suitable for poor water quality conditions.
