With a unique brush - cleaning technology, it enables automatic cleaning of the filter element, ensuring continuous and stable high - efficiency filtration, providing reliable solutions for industrial and civil water use.

I. Product Introduction

The brush self - cleaning filter is an advanced water treatment device that integrates high - efficiency filtration and intelligent self - cleaning functions. Inside the device, a stainless - steel wedge - wire screen is set as the main filter element. The water to be treated flows into the filter from the inlet. After being filtered by the screen, impurities are intercepted on the outside of the screen, and the purified water flows out from the outlet. When the impurities intercepted by the screen cause the pressure difference between the inlet and outlet to reach the set value, or the running time reaches the preset duration, the device automatically starts the cleaning program. The brush head is driven by a motor to rotate and scrub the surface of the screen. At the same time, the drain valve opens to discharge the scrubbed impurities. There is no need for manual disassembly and cleaning, effectively improving the operation efficiency and service life of the device. It is widely used in industrial circulating water, agricultural irrigation, municipal water supply, and other fields.

II. Working Process

1. Normal Filtration Stage:

• Raw Water Inflow: The raw water enters the device from the filter inlet through the pipeline under the pressure of the water pump and is evenly distributed to the outside of the screen.

• Impurity Interception: The water flows through the screen from the outside to the inside. Impurities such as suspended solids, sediment, rust, and algae in the water are intercepted by the screen. The purified water is collected through the inside of the screen and sent to the subsequent water - using links.

2. Cleaning Trigger:

• Pressure Difference Trigger: As the filtration progresses, impurities on the surface of the screen continue to accumulate, causing the pressure difference between the inlet and outlet of the filter to rise. When the pressure difference reaches the set value (generally 0.05 - 0.1MPa), the system automatically triggers the cleaning program.

• Time Trigger: If the raw water quality is good and the pressure difference increases slowly, when the device running time reaches the preset duration (such as 8 - 24 hours), the cleaning program will also be started to ensure that the screen is cleaned in time.

3. Self - Cleaning Process:

• Brush Head Rotation and Scrubbing: The motor starts and drives the brush head to rotate along the inner wall of the screen. Through the mechanical friction of the bristles, the impurities attached to the surface of the screen are scrubbed off.

• Debris Discharge: At the same time, the drain valve opens. Under the pressure of the water flow, the scrubbed impurities are discharged from the filter through the drain port. The entire cleaning process only takes tens of seconds to a few minutes.

4. Restoring Filtration Stage: After the cleaning is completed, the drain valve closes, the brush head stops rotating, and the device resumes the normal filtration state.

V. Application Fields

1. Industrial Production Water:

• Iron and Steel Metallurgy: Used for the filtration of steel rolling cooling water and blast furnace slag flushing water, intercepting impurities such as iron oxide scale and suspended solids, protecting cooling equipment, and improving cooling efficiency.

• Petrochemical Industry: Filters chemical raw material liquids and circulating cooling water, removing catalyst particles, oil stains, etc., ensuring the stable operation of the production process and reducing equipment failures.

• Power Industry: Filters the circulating cooling water and boiler makeup water of power plants, preventing impurities from causing scaling of condensers and blockage of boiler pipes, and ensuring the safe operation of the units.

2. Agricultural Irrigation Field:

• Drip Irrigation and Sprinkler Irrigation Systems: Filters sediment, organic matter, algae, etc. in irrigation water, preventing the blockage of drip heads and sprinkler heads, and ensuring uniform irrigation and efficiency.

• Aquaculture: Purifies the circulating water in aquaculture ponds, removes pollutants such as feces and uneaten bait in the water, improves water quality, and creates a good environment for aquaculture.

3. Municipal Water Projects:

• Waterworks: As a raw water pretreatment device, it removes impurities such as sediment, algae, and colloids in the water, improving the quality of the treated water.

• Sewage Treatment Plants: In the advanced sewage treatment process, it filters the residual suspended solids, making the effluent meet the reuse standards.

4. Commercial and Civil Buildings:

• Central Air - Conditioning Systems: Filters the impurities in chilled water and cooling water, prevents the scaling of heat exchangers, improves the energy efficiency of air - conditioning systems, and extends the service life of equipment.

• Community Secondary Water Supply: Ensures the quality of residents' domestic water and removes rust, sediment, and other impurities that may exist in the pipes.

VI. FAQ

1. How to determine the cleaning frequency of the brush self - cleaning filter?The cleaning frequency is determined by the raw water quality, water treatment volume, and filtration precision. When the raw water contains more impurities, the water treatment volume is large, or the filtration precision is high, the cleaning frequency will increase; otherwise, it will decrease. Generally, the cleaning can be automatically triggered by pressure difference setting (such as 0.05 - 0.1MPa) or time setting (8 - 24 hours), and it can also be manually adjusted according to the actual operation situation.

2. How often does the screen need to be replaced?The service life of the screen is related to the raw water quality and cleaning effect. Under normal working conditions, the stainless - steel screen can be used for 5 - 8 years. If the raw water quality is poor or the cleaning is not thorough, the service life of the screen will be shortened. When the filtration effect is significantly reduced and cannot be restored by cleaning, the screen needs to be replaced in time.

3. What matters need to be paid attention to during the installation of the device?During installation, it is necessary to ensure that the inlet and outlet directions of the device are correct and that the connection with the pipeline is firm. The device should be installed on a horizontal foundation to ensure stable operation. If the system pressure is unstable, a pressure - stabilizing device needs to be installed. At the same time, enough space should be reserved for equipment maintenance and brush head maintenance.

VII. Conclusion

The brush self - cleaning filter, with its intelligent and efficient self - cleaning function, stable and reliable filtration performance, and wide application adaptability, has become an ideal device for water treatment in various industries. Whether it is to ensure the continuous and stable operation of industrial production or to improve the water quality in agricultural, municipal, and civil fields, it can play a crucial role. Choosing our brush self - cleaning filter means choosing an efficient, convenient, and durable water treatment solution, escorting the stable operation of your water - using system.
