A Brush Type Self-Cleaning Filter is a specific kind of filtration system that is extremely beneficial in various industrial settings. It is designed to eliminate suspended solids from liquids like water, particularly in industrial applications where these solids need to be removed.

Unlike traditional filters that require manual intervention to clear accumulated contaminants, this type of filter is automatic and can operate continuously without downtime. It is installed with a set of stainless steel brush, or sucking scanner, or a combination of both. This device is driven by the gear reduction motor rotation, and an electric sewage valve is installed on the filter end cover or bottom.

This filter is characterized by its large filtration area and high dirt-holding capacity. It's designed to be user-friendly, with a simple cleaning method. The cleaning cycle is monitored to realize automatic cleaning and discharging. All parameters in the automatic filter control system can be adjusted, and it is equipped with motor overload protection, which can effectively protect the motor.

This type of filter is a crucial component in ensuring the production of safe and clean water for various applications, improving the quality of water significantly.

Self-cleaning filter with filtration accuracy from 50 to 5000 microns can be selected, with large filtration area and high dirt-holding capacity, which can be customized by users according to actual working conditions. The cleaning method is simple, and the cleaning cycle is monitored to realize automatic cleaning and discharging, and all parameters in the automatic filter control system can be adjusted. It is equipped with motor overload protection, which can effectively protect the motor.

The self-cleaning filter has a variety of applications across different sectors, showcasing its versatility and efficiency. These include:

Agricultural Irrigation: The filter is used to remove suspended particles, dirt, and bacteria from the water used for irrigation. This ensures that the water is clean and safe for use in agricultural fields, promoting healthier crop growth and reducing the risk of disease transmission.

Raw Water Treatment: In raw water treatment processes, the filter effectively removes particulate matter, water dirt, bacteria, algae, and rust. This is crucial in ensuring the treated water is safe for various uses, including human consumption.

Industrial Circulating Water Filtration: Industries that rely on water circulation systems for their processes also utilize these filters. They help to maintain the cleanliness and safety of the circulated water by removing impurities.

Cooling Water Treatment: In cooling systems, the filter helps to remove impurities that might affect the efficiency of the cooling process or pose a risk to the equipment.

Paper Industry: The paper industry uses large amounts of water in its processes. The filters help ensure the water is clean and free of impurities that could affect the quality of the paper products.

Plastic Industry: Similar to the paper industry, the plastic industry also uses water in its manufacturing processes. The filters help to maintain the quality of this water.

Power Industry: Power plants often use water for cooling and other processes. The filters ensure this water is clean and safe for use, protecting the equipment and maintaining efficiency.

As for the filtration media, the self-cleaning filter is designed to remove various contaminants from the water. These include water body suspended matter, particulate matter, water dirt, bacteria and algae, rust, etc. This makes it a highly effective solution for maintaining clean and safe water in a multitude of applications.

Product Features

It adopts electromechanical integration design. The automatic self-cleaning filter is composed of main parts such as driving mechanism, control pipeline (including differential pressure switch), main tube assembly, filter element assembly, cleaning mechanism and connecting flange. The electric controller, control pipeline and drain valve constitute the control part of the filter, which is used to realize the automatic cleaning and discharging process. The control pipeline consists of accessories such as differential pressure switches, pipe joints and brass pipes. The filter uses stainless steel brushes for conventional products, and other materials of brushes.

The working principle of the automatic self-cleaning filter is quite fascinating and efficient.

The filter has the capability of filtering raw water, automatically cleaning the filtration element, and discharging it. What's impressive is that during the cleaning and discharging process, the system continues with the water supply without any interruptions.

The automatic self-cleaning filter has two control methods: automatic control and manual control.

Automatic Control:
Automatic control is further divided into two methods: timing and differential pressure. When it operates on timing, the filtering time is preset on a timer. Once this time is reached, the discharge process begins. The time for discharge is also set by a discharge timer.

Simultaneously, the control system constantly compares the system pressure difference with the user-set pressure difference. When the system pressure difference reaches the set pressure difference, the filter initiates the cleaning and discharging process. Again, the discharge time is set by the discharge time timer.

Once the discharge time is up, the cleaning stops, and the system reverts to its initial state, ready for the next round of filtration.

Manual Control:
In terms of manual control, the manual/automatic selector switch on the operation panel is turned to the manual position. This action triggers the filter to discharge.

This working principle of the automatic self-cleaning filter ensures efficient filtration, automatic cleaning, and uninterrupted water supply, making it an excellent choice for various applications.

The automatic self-cleaning filter comes with a range of product advantages that set it apart from other filtration systems. These include:

Internal Scraper System: This system ensures efficient and thorough cleaning of the internal surfaces of the filter, reducing the build-up of impurities and maintaining the filter's optimal performance.

PLC Control System: The Programmable Logic Controller (PLC) control system allows for automatic identification of the degree of deposition of internal impurities. This system provides a variety of control modes, including differential pressure control, time setting control, and manual control. This adaptability allows for precise and efficient operation.

High-Performance Precision Filter Element: This filter element, made from 304/316L stainless steel wedge-shaped metal mesh, supports customization from 20-500μm. It's non-clogging, easy to clean, and results in low pressure loss and low maintenance cost. It is also suitable for liquids with a viscosity of up to 8000 cP.

Key Components of the Equipment: The equipment features key components, including a bipolar reducer and electrical components, chosen for their quality and reliability. It operates using a PLC Siemens control system and has the option of an electric ball valve. These features ensure the whole equipment system runs efficiently and stably.

With these advantages, the automatic self-cleaning filter is a reliable and efficient choice for various applications.
