Overview of Automatic Brushing Filters:

Automatic brush filter is a type of self-cleaning filter, which also includes suction self-cleaning filter (also known as suction self-cleaning filter) and automatic backwashing sewage filter.

Working principle of automatic brush filter:

When the water flows through the filter, mechanical impurities in the water are intercepted by the filter screen. When the impurities accumulated on the surface of the filter screen increase and the pressure difference reaches the set pressure difference, the pressure difference switch sends a signal, and the PLC sends a command to start the transmission motor and open the drain valve. The impurities deposited in the filter screen are brushed by the rotating brush and discharged from the drain outlet. The entire brushing and discharging process does not require personnel operation or shutdown. At the same time, the equipment also has regular cleaning and manual cleaning functions to ensure reliable water discharge in any situation.

Automatic brush filter function:

1. Remove suspended solids from the water

2. Reduce suspended solids concentration, particulate matter, and turbidity in water

3. Purify water quality, reduce system dirt, bacteria, algae, and rust

4. Precision equipment for purifying water quality and protecting other equipment in the system from normal operation

Automatic brush filter control mode:

There are two control methods for cleaning automatic brush filters: automatic control and manual control.

Automatic control: Automatic control has two methods: timing and pressure difference. Set the filtering time on the filtering timer. When the filtering time is up, start the sewage discharge, and the sewage discharge time is set by the sewage discharge time timer; At the same time, the control system compares the system pressure difference with the user set pressure difference in real time. When the system pressure difference reaches the set pressure difference, the filter also cleans and discharges, and the discharge time is set by the discharge time timer. After the discharge is completed, stop cleaning, and the system returns to its initial state, preparing for the next filtration process.

Manual control: Press the manual button "cleaning" on the operation panel to clean and drain the filter.

Users can choose two control methods according to their needs, and the specific operation is described in the operation section later.

Features of automatic brush filter:

1. The automatic brush filter has a filtration accuracy ranging from 100 to 3000 microns, with a large filtration area and high pollutant holding capacity. Users can customize it according to their actual working conditions.

2. The cleaning method is simple, and the cleaning cycle is monitored, which can achieve automatic cleaning and sewage discharge. The parameters in the automatic filter control system can be adjusted.

3. Equipped with motor overload protection, it can effectively protect the motor.

4. It has the characteristics of uninterrupted water supply and no need for bypass during cleaning and sewage discharge, with short cleaning time and low sewage consumption, not exceeding 1% of the total flow rate.

5. Strong maintainability, easy to install and disassemble.

6. The connection method with the user pipeline is flange connection, and the flange adopts standard flange, which has strong universality.
