Highly Automated Automatic Self-Cleaning Filter

The highly automated automatic self-cleaning filter is designed to continuously filter and automatically remove suspended particulate matter from water. This device is widely used in industrial circulating water systems, drinking water treatment, wastewater treatment, and many other fields that require high-quality water quality. It ensures uninterrupted filtration through an integrated cleaning mechanism, greatly improving efficiency and reducing maintenance costs.

 

Key structural components

1. Cartridge and screen

The heart of a highly automated automatic self-cleaning filter is its cartridge and internal filter screen. Filters are typically made of high-strength wedge-shaped or woven composites to accommodate different filtration accuracy requirements, ranging from 3000 microns to 10 microns. These filters are designed to efficiently capture impurities while allowing water to flow through smoothly.

2. Backwash mechanism

Including backwash suction cups, electric valves and other components. When the set cleaning conditions are reached, the backwash mechanism will start, and the filter screen will be cleaned by reverse water flow or mechanical brushing to restore its filtration efficiency.

3. Control system

This includes an electronic controller, PLC, differential pressure switch, time controller, etc. These components work together to monitor the operating status of the filter and automatically trigger the cleaning process based on differential pressure, time, or other preset parameters.

4. Drive mechanism and gear reducer

For mechanical cleaning filters, the drive mechanism and reducer control the action of the cleaning brush or suction cup to ensure accurate and effective cleaning.

 

Working principle

1. Normal filtering stage

The water flow enters the filter through the water inlet, intercepts impurities through the filter screen, and the clean water flows out through the filter screen for subsequent use or circulation system.

2. Cleaning trigger mechanism

When the accumulated impurities on the filter screen cause the pressure difference between the front and rear to reach the preset value, or according to the preset time interval, the control system will automatically activate the cleaning program.

3. Cleaning process

- Backwashing. Switch valve, so that the direction of water flow is reversed, high-speed water flow or air flow to flush the filter screen, wash away impurities.

- Mechanical scrubbing. The built-in brush rotates or moves to physically scrape away deposits from the filter.

- Sewage discharge. During the cleaning process, impurities are discharged from the filter and discharged to the designated collection place through the sewage valve.

6. Pharmaceutical and Biotechnology. Provide high-standard purified water for the production process.

 

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.
