Self-clean Filter Promote The Reuse Of Water Resources, Saving Water Resources
- Aug 11, 2017 -

In recent years, the shortage of water resources, the shortage has become the bottleneck of economic development, in real life, human beings in order to meet the needs of life and production, from a variety of natural water to take a lot of water. Domestic water and industrial water after use to become domestic sewage and industrial wastewater, they are discharged, and eventually discharged into the natural water. In this way, water in human society, also constitutes a local circulation system, this system has become a social cycle. At the same time, such a cycle has also had a serious impact on water resources. So the installation of Self-clean Filter to use, so that the factory sewage and living sewage is no longer directly discharged into the natural water, and promote the reuse of water resources, saving water resources.

Self-clean Filters have a number of significant advantages over conventional filters. It broke the original structural design pattern, so that it can not only filter the raw water, but also can automatically clean, sewage, and can also uninterrupted water supply. But the Self-clean Filter in the use of the filter results will be caused by the user troubles, then what causes the Self-clean Filter filter effect? First through several types of Self-clean Filter principle to analyze the next:

Brush Self-clean Filter to be treated by the water from the inlet into the body, the impurities in the water deposited on the stainless steel filter, resulting in pressure. Through the differential pressure switch to monitor the inlet and outlet pressure changes, when the pressure reaches the set value, the electronic control to the hydraulic control valve, drive the motor signal, causing the following actions:

The motor will drive the brush to rotate, the filter will be cleaned, and the control valve will open for the sewage. The entire cleaning process will take only tens of seconds. When the cleaning is finished, the control valve will be closed and the motor will stop and the system will return to its original state. The next filtration process. After the installation of the equipment, by the technical staff to debug, set the filter time and cleaning conversion time, the water to be treated by the inlet into the body, the filter began to work properly, when the preset cleaning time, the electronic control to the hydraulic control valve , Drive the motor signal, causing the following actions:

The motor will drive the brush to rotate, the filter will be cleaned, and the control valve will open for the sewage. The entire cleaning process will take only tens of seconds. When the cleaning is finished, the control valve will be closed and the motor will stop and the system will return to its original state. The next filtration process.

The Self-clean Filter is fed from the inlet, first through the coarse filter to filter out the larger particles of impurities, and then reach the fine filter. In the filtration process, the fine filter gradually accumulates the dirt and impurities in the water to form a filter impurity layer. Since the impurity layer is deposited on the inside of the fine filter, a pressure difference is formed on both inside and outside of the fine filter The

When the pressure difference of the filter reaches the preset value, it will start the automatic cleaning process, where the water supply is constantly flowing, the cleaning valve is opened, the water pressure in the washing room and the sucker is greatly reduced, Pressure difference between the suction pipe and the cleaning chamber through the suction nozzle to produce a suction to form a suction process. At the same time, the filter electric motor drives the suction pipe to do spiral motion in the axial direction.

The combination of axial movement and rotary motion of the suction filter completely cleans the entire surface of the filter. The entire rinse process takes only ten seconds. The drain valve closes at the end of the wash. The Self-clean Filter begins to prepare for the next rinse cycle.

And the backwashing of the Self-clean Filter from the water inlet into the filter, first through the coarse filter element filter out the larger particles of impurities, and then reach the fine filter, fine filter through the fine particles of impurities, Outlet. In the filtration process, the fine filter of the inner layer of impurities gradually accumulate, its inside and outside on both sides of the formation of a pressure. When the pressure difference reaches the preset value, the filter will begin the automatic cleaning process: the drain valve opens, the hydraulic unit of the main assembly and the hydraulic cylinder release the pressure and the water is discharged; the pressure in the hydraulic motor chamber and the suction pipe is greatly reduced, As a result of negative pressure, through the suction nozzle to suck the dirt inside the fine filter, from the hydraulic motor into the hydraulic motor room, discharged by the sewage valve to form a sewage absorption process. When the water flow through the filter hydraulic motor, driven by the suction pipe to rotate, driven by the hydraulic cylinder piston suction tube for axial movement, the suction device through the axial movement and the combination of rotation movement of the entire screen completely clean the inner surface The The entire cleaning process will last for tens of seconds. The drain valve closes at the end of the wash, and the increased water pressure causes the hydraulic cylinder piston to return to its original position and the Self-clean Filter begins to prepare for the next rinse cycle. In the cleaning process, the filter normal filter work uninterrupted.
