Sucking Type Automatic Self-Cleaning Filter

The sucking type automatic self-cleaning filter detects and removes impurities on the filter screen by sucking action to achieve uninterrupted water filtration and self-cleaning process. This filter is a high-efficiency, fully automatic water filtration device, suitable for a variety of industrial and agricultural applications, such as cooling water systems, irrigation systems, groundwater filtration, etc.

Structure composition

The sucking type automatic self-cleaning filter is mainly composed of the following parts:

1. Filter cartridge. Usually made of stainless steel or other corrosion-resistant materials, with coarse and fine filters inside.

2. Suction scanner. A device used to detect impurities in the filter net, usually rotating, covering the entire filtration area.

3. Drain valve. Used to discharge filtered pollutants during the cleaning process.

4. Backwash mechanism. When the cleaning cycle starts, the filter is backwashed to remove any attached impurities.

5. Control system. Including sensors, PLCs (programmable logic controllers), etc., used to monitor the working status of the filter and control the self-cleaning process.

Working principle

The working process of a sucking type automatic self-cleaning filter is divided into two stages: the filtration stage and the self-cleaning stage.

1. Filter stage

The liquid to be filtered enters from the water inlet of the filter and is trapped by the impurities through the coarse and fine filters. With the continuous accumulation of impurities, the aperture of the filter screen is gradually blocked, and the resistance of the liquid through the filter screen increases. At this time, the sucking scanner starts to work, detects the impurities on the filter screen and transmits a signal to the control system.

2. Self-cleaning stage

When the control system receives the signal, the cleaning cycle is started. First, the sewage valve is opened, allowing a part of the filtered liquid to be discharged directly out of the water outlet, which can avoid impurities from re-mixing into the system during the cleaning process. Then, the backwash mechanism starts to work, and the coarse and fine filters are backwashed, and the impurities are peeled off from the surface of the filter screen and discharged with the water flow. After cleaning is completed, the sewage valve is closed, and the filter returns to its normal filtration state.

Specifications

Advantages

1. Fully automatic operation: Without manual intervention, water filtration and self-cleaning can be carried out 24 hours a day without interruption.

2. High efficiency. Sucking detection can quickly detect the accumulation of impurities and clean them in a timely manner to ensure filtration efficiency.

3. Compact structure. Small footprint for easy installation and maintenance.

4. Low maintenance costs. Simple design, reducing failure rates and maintenance costs.

5. Synchronization of sewage discharge and filtration. It can still maintain a certain filtration effect during the cleaning process without affecting the normal operation of the system.

6. Strong adaptability. Can handle liquids of different viscosities, suitable for a variety of working conditions.

Application

The sucking type automatic self-cleaning filter is widely used in many fields due to its high efficiency and reliability.

- Industrial cooling water system. Used to filter impurities in circulating water and protect equipment from contamination.

- Groundwater treatment. Used to remove suspended solids and solid particles from groundwater to improve water quality.

- Agricultural irrigation. Used to filter sediment and debris from farmland irrigation water and protect sprinkler irrigation equipment.

- Food and beverage industry. Filtration of water sources and processing fluids during production.

- Pharmaceutical industry. High-precision filtration is required during the preparation of pure water and the clarification of liquid medicine.

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.
