The principle of a self-cleaning filter or a self-cleaning filter.

Century Source 1Filtration: The raw water enters the body from the water inlet, flows through the filter screen, and filters out the fine impurities in the water, with the accumulation of various pollutants in the filter medium on the inside of the filter screen, the filter channel is blocked, and the pressure difference between the inlet and outlet gradually increases.

2.High-pressure backwashing: when the pressure difference reaches the preset value, the system automatically starts the stroke motor and the backwashing high-pressure pump, at this time, the transmission device drives the sewage shaft equipped with a suction nozzle to rotate and horizontal round-trip movement on the inside of the filter screen, at the same time, on the outside of the filter screen, the high-pressure backwashing device and the sewage discharge device act synchronously, and there is a corresponding relationship, under the premise of not interrupting the normal water production, only with the help of a small part of the product water, the filter screen is backwashed, the backwash water penetrates the filter screen, and the impurities peeled off from the filter screen are quickly sucked into the sewage shaft by the suction nozzleand finally discharged by the sewage chamber.

3.Reset: After a backwash stroke, the differential pressure is reduced, the components are reset, and the system re-enters the normal operation state.

This is: The working principle of Qinhuangdao Century Source Water Treatment Technology **** Other homes are different according to the principle of their own equipment

Hope this helps.

How the self-cleaning filter works:

1.The water to be filtered enters through the inlet, first through a coarse strainer to filter out larger particles of impurities, and then to a fine strainer.

2.In the filtration process, the fine filter gradually accumulates dirt and impurities in the water to form a filter impurity layer, because the impurity layer is accumulated on the inner side of the fine filter, so a pressure difference is formed on the inner and outer sides of the fine filter.

3.When the pressure difference of the filter reaches the preset value, the automatic cleaning process will begin, during which the water purification will continue to flow, the cleaning valve will be opened, the water pressure in the cleaning chamber and the suction device will drop significantly, and the pressure difference between the filter cartridge and the suction pipe will generate a suction force between the suction pipe and the cleaning chamber through the suction nozzle to form a suction process.

4.At the same time, the electric motor drives the suction pipe to do spiral motion along the axial direction. The combination of axial and rotational movements of the suction cleans the entire inner surface of the strainer completely.

5.The whole rinsing process takes about a few tens of seconds. At the end of the cleaning, close the blowdown valve. The filter begins to prepare for the next flushing cycle.

The principle of my friend's self-cleaning filter is that he stirs it inside like a washing machine to wash off the stains on the filter.

How the self-cleaning filter works:

The water enters through the inlet, first through a coarse filter to filter out larger impurity particles, and then to a fine filter. During the filtration process, the fine filter gradually accumulates dust and impurities in the water, forming a layer of filter impurities. As the impurity layer accumulates on the inside of the microfilter, a pressure difference forms between the inside and outside of the microfilter.

When the differential pressure of the filter reaches the preset value, the automatic cleaning process will begin. During this time, the clean water source is constantly flowing, the cleaning valve is opened, and the water pressure in the clean room and sewage suction unit drops significantly, passing through the filter element and suction pipe. Due to the pressure difference, suction is created between the nozzle and the clean chamber, resulting in an inhalation process.

At the same time, the electric motor drives the straw to do a spiral motion in the axial direction. The combination of axial and rotational movements of the vacuum cleaner completely cleans the entire inner surface of the filter. The entire rinsing process takes only a few tens of seconds.

At the end of cleaning, the drain valve is closed. The filter is ready for the next rinse cycle.

The filtration principle of the self-cleaning filter is the same as that of ordinary filtration, but with an additional automatic cleaning process, there is no need to manually take out the filter for cleaning.

Self-cleaning filter principleThe water quality flows in from the inlet of the equipment, and the larger impurities will be filtered through the coarse filter screen, and the filtered water quality flows through the fine filter screen, when the equipment is in the process of filtration, the impurities in the water quality and other garbage will gradually accumulate in the fine filter screen, and the filter magazine layer will be formed, because the impurities will generally accumulate in the inner part of the fine filter screen, so the fine filter screen in the equipment, the outer two sides will form an unbalanced pressure difference. If the pressure difference between the self-cleaning filter reaches the preset value, the equipment will start the cleaning process of self-cleaning, during this period can not cut off the water, after the cleaning valve is opened, the heavy water pressure of the cleaning chamber and the sewage suction device will cause a significant drop, you can use the pressure difference between the filter cartridge and the suction pipe, between the suction pipe and the cleaning chamber, the suction force will be generated through the action of the suction nozzle, and a suction process will be formed in the equipment. During this period, the electric motor will drive the suction pipe to run in a spiral, and its rotation can completely clean the surface of the filter screen, and the cleaning process only takes more than ten seconds.

At the end of cleaning, the blowdown valve is closed and the self-cleaning filter enters the next cleaning cycle.

Advantages of self-cleaning filters:The filtration accuracy of self-cleaning is generally 100 microns by default, the specifications of the filtration accuracy can be selected in the range of 100-3000 microns, the filtration area of the equipment is up, the dirt-holding capacity is very high, and it can be customized according to the needs of users when making, the cleaning method of the self-cleaning filter is simple, the self-cleaning cycle and electronic monitoring can be carried out, and the automatic cleaning and sewage function is realized, and the control system of the self-cleaning filter can be adjusted according to the needs of production.

When the water enters the inside of the filter cartridge from the water inlet, the impurities are intercepted on the inner wall of the filter cartridge, and the filtered clean water flows out from the water outlet, when the impurities on the inner wall of the filter cartridge accumulate more and more, the pressure difference between the inlet and outlet of the filter reaches the preset value or reaches the cleaning time or manual prefabrication, the filter will start the self-cleaning process, and the whole self-cleaning process contains two steps: open the automatic blowdown valve located on the filter; The motor drives the cleaning brush in the filter screen, and the impurities intercepted by the filter screen are discharged from the blowdown valve. The system is constantly flowing during cleaning, and the entire operation of the filter is controlled by an intelligent control box equipped with it.

The control mode can be controlled by differential pressure, time, manual and PLC.

The principle of filtration is not the same.

Self-cleaning filter filtration principle: liquid flows in from the inlet, the scraper with compensation is close to the inner surface of the filter screen, the liquid flows outward from the inner surface of the filter element through the filter screen, the impurities are trapped on the inner surface, and the liquid flows out from the outlet; Over time, the impurities gradually increase and the differential pressure increases, so clean the filter according to the set differential pressure or at regular intervals. When the scraper rotates, the impurities are scraped off by the scraper and flow to the bottom of the filter, and the impurities with large specific gravity precipitate into the sewage collection cavity.

Each cleaning consists of several strokes, and after the surface of the filter is cleaned, the filtration capacity is restored. Normal filtration during cleaning, uninterrupted flow rate. After multiple cleaning cycles, impurities have accumulated to a certain amount, and the blowdown valve is opened regularly to discharge the waste liquid containing high concentrations of impurities, if necessary.

Backwash filter filtration principle:

The liquid flows in from the filter inlet, part of the liquid directly enters the filter from the lower end of the filter element, and the other part enters the top of the filter from the middle manifold pipe, and then flows from the upper end of the filter screen, and the liquid flows in from the upper and lower openings of the filter screen at the same time, and flows out through the inner surface of the filter screen at the outlet. Particulate impurities are intercepted on the inner surface of the filter screen and accumulate into a filter cake, which gradually increases the pressure difference between the inlet and outlet, indicating that the filter cake reaches a certain thickness, and the filter flux gradually decreases. When the set pressure difference or time is reached, the self-cleaning action starts, the geared motor drives the backwash swivel arm to align with a filter or a group of filters, the upper part of the filter screen is sealed, the lower end is connected to the cleaning nozzle, the backwash valve is opened, the filter screen is connected with the sewage pipe, and the pressure difference between the outside of the filter screen and the sewage outlet drives the filter liquid to flow in reverse to flush the filter cake on the inner surface of the filter screen, and discharge it into the sewage pipeline.

After the backwashing of one group of filter elements is completed, close the backwashing valve, and the cleaning arm is aimed at the next group of filter screens for backwashing. After all the strainers have been backwashed one by one, the whole process is complete.

Filtering liquids is not the same.

Self-cleaning filters can be used with a variety of liquids such as: water, resin, coatings, polymers, adhesives, citric acid, fermentation broth, chitosan, cosmetics, agarose (gel), silicone solution, soap, sorbitol, steroids, cereal syrup, wet-end additives, pigments, lubricants, rubber, ethanol, mixed oils, edible oils, high temperature oils, fruit juices, diesel, etc.

The backwash filter cannot adapt to high viscosity liquids, and is only suitable for water filtration, such as groundwater, seawater, lake water, reservoir water, circulating cooling water, chilled water, spray water, heat exchange water, sealing water, bearing cooling water, oil well water injection, process circulating water, machining coolant, cleaning water, etc.
