Automatic Brush Type Self-Cleaning Filter

The automatic brush type self-cleaning filter is a high-efficiency filtration equipment, suitable for various industrial water treatment scenarios, such as cooling water circulation system, process water pretreatment, wastewater treatment, etc. It maintains the continuous and efficient operation of the filter screen through automatic cleaning function, thus reducing manual intervention and maintenance costs.

 

Working principle

The core part of the automatic brush type self-cleaning filter is a metal filter screen, usually made of stainless steel, with different precision grades to suit different filtration needs. When the water flows through the filter screen, impurities are intercepted inside the filter screen, and the clean water flows into the water outlet through the filter screen. As impurities accumulate, the pressure difference between the inside and outside of the filter screen will gradually increase. When the pressure difference reaches a preset value, or the timer time is reached, the self-cleaning process will be triggered.

Self-cleaning process

1. The sewage valve is opened. The automatic sewage valve is located at the bottom of the filter and is used to discharge the waste residue generated during the cleaning process. The sewage discharge process can be carried out without affecting the normal operation of the system.

2. Brush cleaning. The motor drives one or more brushes to rotate, and the brushes rotate along the inner surface of the filter screen to remove impurities attached to it. This mechanical cleaning method can effectively remove solid impurities and some colloidal substances on the filter screen.

3. Impurity discharge. With the rotation of the brush, the impurities brushed off the filter flow with the water to the sewage valve, and are discharged from the filter by the sewage valve.

 

The control system

The intelligent control box of the automatic brush type self-cleaning filter can realize a variety of control methods, including differential pressure control, time control, manual control, and PLC control.

1. Differential pressure control. The differential pressure is monitored by a pressure sensor installed at the filter inlet and outlet. When the differential pressure reaches a preset value, the system starts-up the cleaning program.

2. Time control. Perform periodic cleaning according to the running time of the filter to avoid clogging the filter screen due to long-term failure to clean.

3. Manual control. The operator can trigger the cleaning process through the manual button of the control box, so that the filter can be maintained and cleaned at any time.

4. PLC control. Programmable logic controllers (PLCs) can be integrated into higher-level control systems for remote monitoring and operation, meeting the needs of more complex industrial automation.

 

Device features

1. Continuous water supply. Self-cleaning process without stopping the water flow, to achieve uninterrupted water supply system.

2. Energy-saving and efficient. Automatic cleaning through differential pressure or time control, reducing energy waste and prolonging the service life of the filter.

3. Automatic sewage. The design of the automatic sewage valve simplifies maintenance operations and reduces labor costs.

4.Modular design. Easy to install and maintain, and can be used in combination with single or multiple devices according to different traffic requirements.

5. Wide applicability. Can be used for a variety of water quality conditions, such as surface water, groundwater, seawater desalination, etc.

FAQ

1. Q: What is the function of a filter?

A: The main function of a filter is to remove solid particles, impurities, and harmful substances from liquids or gases, in order to achieve purification, clarification, and protection of equipment.

2. Q: How to choose a suitable filter?

A: When choosing a filter, factors such as the properties of the material being filtered (e.g., viscosity, temperature, corrosion), required filtration accuracy, processing capacity, operating pressure and medium, as well as the type, material, size, and installation method of the filter should be considered.

3. Q: What is the working principle of a filter?

A: The working principle of a filter mainly relies on physical screening, deep interception, absorption, or chemical reactions to remove impurities or harmful components from the material being filtered.

4. Q: How to maintain and care for a filter?

A: Maintenance of filters includes regular cleaning or replacement of filter elements, inspection of seals and fasteners, maintaining stable operating pressure, and avoiding overloading. Specific methods should be referenced from the filter's instruction manual and maintenance guides.

5. Q: What is the service life of a filter?

A: The service life of a filter depends on its working environment, processing volume, and filtration accuracy. Generally, when the filter's pressure drop reaches a certain value or the filtration effect decreases significantly, it needs to be replaced or cleaned.

6. Q: What should be paid attention to during filter installation?

A: During filter installation, attention should be paid to the directionality, ensuring that the fluid enters and exits from the correct ports. Also, the piping system should be cleaned before installation, and the filter should be securely fastened and sealed as required by the instructions.

7. Q: What is the replacement cycle for filters?

A: The replacement cycle for filters depends on their working conditions and filtration requirements, and is usually indicated by pressure difference indicators or timers. When the filter's pressure drop reaches the set value or the filtration effect decreases, it should be replaced in a timely manner.
