Product details of automatic backwashing filter

Product overview

The automatic backwashing filter is a high - efficiency and intelligent filtering device, which is widely used in industrial, agricultural, municipal and other fields. It can effectively remove impurities, suspended solids, etc. in water, ensuring the cleanliness and stability of water quality. It has the advantages of high automation, good backwashing effect, low operating cost, etc., providing users with a convenient and reliable filtering solution.

Working principle

The automatic backwashing filter is mainly composed of a filter tank, filter screen, differential pressure controller, electric valve and other components. When water enters the filter from the water inlet, it is filtered through the filter screen. Impurities are intercepted inside the filter screen, and clean water flows out from the water outlet. As the filtering progresses, the impurities inside the filter screen gradually increase, resulting in an increase in the differential pressure on both sides of the filter screen. When the differential pressure reaches the set value, the differential pressure controller sends a signal, the electric valve opens, and backwashing starts. During backwashing, the water flow reverses, flushing away the impurities inside the filter screen and discharging them through the sewage outlet. After the backwashing is completed, the electric valve closes, and the filter returns to the normal filtering state.

Product features

High - efficiency filtering

Using a high - precision filter screen, it can effectively intercept various impurities in water. The filtering accuracy can reach the micron level, ensuring the quality of the effluent water.

Automatic backwashing

Automatic backwashing is realized through the differential pressure controller and the electric valve without manual intervention, saving labor costs.

Good backwashing effect

During backwashing, the water flow reverses, which can thoroughly remove the impurities inside the filter screen, ensuring the permeability of the filter screen.

Low operating cost

The water consumption for backwashing is small, and the energy consumption is low, reducing the operating cost.

Long service life

Made of high - quality materials, it has a strong structure, is corrosion - resistant, and has a long service life.

Technical parameters

Filtering accuracy

Different filtering accuracies can be selected according to user needs. Common ones are 100 microns, 200 microns, 300 microns, etc.

Flow range

According to different models and specifications, the flow range varies from several cubic meters per hour to hundreds of cubic meters per hour.

Working pressure

Generally, it is 0.2 - 1.0 MPa, which can be adjusted according to actual needs.

Backwashing time

The backwashing time can be set according to the actual situation, generally 1 - 3 minutes.

Application fields

Industrial field

It can be used for circulating water filtration in industries such as chemical, power, metallurgy, and papermaking, ensuring the normal operation of equipment.

Agricultural field

It can be used for irrigation water filtration, preventing nozzle blockage and improving irrigation efficiency.

Municipal field

It can be used for water purification in water treatment plants and sewage treatment plants, improving water quality.

Installation and maintenance

Installation

The installation of the automatic backwashing filter is relatively simple. Just install the filter on the pipeline and connect the water inlet, water outlet and sewage outlet. During installation, attention should be paid to keeping the filter horizontal and vertical to avoid tilting.

Maintenance

Regularly check the operating status of the filter, observe the display value of the differential pressure controller, and perform backwashing in time. Regularly clean the filter screen to remove impurities on the surface of the filter screen, ensuring the permeability of the filter screen. Regularly check the working status of the electric valve to ensure its normal opening and closing.
