Fully Automatic Brush Type Self Cleaning Filter

The fully automatic brush type self cleaning filter is an advanced water treatment device designed for efficient, continuous, and low-maintenance water purification. It combines precision filtration, automatic cleaning, and intelligent control technologies, finding wide application in industrial, agricultural, municipal, and various water circulation systems to ensure stable operation and water quality compliance of water supply systems.

Parameters

Working Principle

The core components of an Automatic Brush-Type Self-Cleaning Filter include a stainless steel filter screen, a stainless steel wire brush, a transmission mechanism, electric valves, a control system, and related auxiliary components. Its working process is as follows:

1. Normal Filtration Stage

Raw water enters the device through the inlet and passes through the filter screen. Contaminants are trapped on the screen's surface while clean water flows through to the outlet for system use. The filter screen's pore size can be selected according to specific requirements, typically ranging from 20 microns to several thousand microns, to meet different applications' water quality demands.

2. Pressure Differential Monitoring & Triggering Cleaning

An internal pressure sensor continuously monitors the change in pressure before and after the filter. When the accumulation of contaminants on the screen causes the differential pressure to reach a preset value, the control system determines that cleaning is necessary. This mechanism ensures the filter operates at its optimal condition, preventing blockages that could lead to decreased flow or elevated system pressure.

3. Automatic Cleaning Process

Upon initiation of the cleaning program, an electric motor drives the stainless steel wire brush to rotate along the inner wall of the filter screen, tightly adhering to the screen and scraping off adhered contaminants. Concurrently, the electric valve switches to backwash mode, reversing the water flow direction to create a high-speed outward flushing action that expels dislodged debris through the drain port. The entire cleaning process is precisely controlled by the control system, lasting only 15 to 60 seconds typically, and consumes only about 1% of the filter's output flow, thus minimally impacting the system's continuous water supply.

4. Cleaning Completion & Resumption of Filtration

After cleaning is complete, the electric valve resets, and water flow returns to normal direction. The filter reenters the filtration state, repeating this cycle for continuous and efficient filtering operation.

Key Features

1. Uninterrupted Water Supply

Due to the rapid and localized nature of the cleaning process, it has minimal impact on overall flow, enabling the filter to maintain continuous system water supply during cleaning, particularly suitable for applications with high water supply stability requirements.

2. High Filtration Precision

By selecting stainless steel filter screens with different precision levels, the filter can achieve filtration grades as fine as 20 microns or even finer, effectively removing suspended solids, particles, colloids, and other impurities, ensuring the safe operation of subsequent equipment or processes.

3. Intelligent Control

Incorporating electromechanical design, the filter is equipped with an advanced control system that automatically initiates cleaning programs based on pressure differential, time, manual commands, or other trigger conditions, enabling fully automated, unmanned operation. The system also features fault alarms and status displays for remote monitoring and maintenance.

4. Energy Efficiency

The cleaning process consumes minimal water and energy, and since regular self-cleaning prevents severe filter clogging that would otherwise increase energy consumption, long-term operating costs are relatively low.

5. Durability & Reliability

The main structure is made of stainless steel, offering excellent corrosion resistance and a long service life. Critical components like motors, valves, etc., are all selected from high-quality elements, ensuring the stability and reliability of the equipment's operation.

6. Ease of Maintenance

Thanks to the automatic cleaning feature significantly reducing the need for manual cleaning, routine maintenance primarily involves simple tasks such as periodic inspections, replacement of worn parts, and clearing of the drainage pipeline, greatly reducing maintenance difficulty and cost.

Applications

The fully automatic brush type self cleaning filter, with its outstanding performance, is widely used across various industries and scenarios:

1. Industrial Sector

Cooling water filtration (e.g., in power plants, chemical, steel industries' circulating cooling water systems), process water filtration (e.g., in pharmaceuticals, food & beverage, electronic semiconductor industries' ultra-pure water pretreatment), wastewater treatment (e.g., as tertiary treatment equipment to enhance effluent quality), and protection of spray nozzles (preventing clogging).

2. Agricultural Irrigation

Pre-treatment of irrigation water sources to remove sand, organic matter, and other impurities, safeguarding irrigation systems and improving water resource utilization.

3. Municipal Water Supply & Drainage

Used in water treatment plants' raw water pretreatment, urban rainwater harvesting systems, front-end filtration in reclaimed water systems, enhancing water quality and ensuring water supply safety.

4. Other Fields

Applications include paper mill white water filtration, injection molding machine cooling water filtration, pasteurization systems, vacuum pump systems, air compressor systems, serving as crucial devices for protecting equipment and optimizing process workflows.

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.
