Preferentially, the structure of the backwash filter and the self-cleaning filter is different. The backwash filter is mainly composed of a barrel, a stainless steel filter, a butterfly valve and a collection and sewage collection and discharge components. In the actual operation of the filter, the butterfly valve is in the open state, and the sewage discharge is in the closed state, so that the liquid can flow from the inlet through the filter screen and then from the outlet.

As another type of purgeable filter, the self-cleaning filter is mainly composed of a driving device, a control pipeline, an electric controller, a main part, a filter element, a blowdown valve, a cleaning device, etc. Among them, the electric controller, blowdown valve and control pipeline are the control parts of the self-cleaning filter, which can automatically clean the blowdown. The control pipeline can be subdivided into differential pressure switches, pipe joints, brass pipes and other components.

Second, the working principle of the backwash filter and the self-cleaning filter is different. In the actual operation, the water flow guide valve is in the open state, and the sewage is in the closed state, so that the liquid enters the backwash filter from the inlet, flows through the filter screen, and then sends it out from the outlet, and the impurities in the liquid will be intercepted in the process of flowing the filter screen. If the backwash filter needs to be discharged, the water flow guide valve is turned off first, and then the sewage valve is opened, so that the liquid will flow through the filter screen, the first half of the liquid is filtered, and part of the liquid will flow into the system after filtration, and the other part of the liquid will be discharged from the outside to the inside after the filter screen, constantly washing the dirty substances on the inner wall, and then sent out through the sewage reservoir.

In the actual operation of the self-cleaning filter, after the liquid enters the filter from the inlet, it first flows through the coarse filter element parts to do preliminary filtration, filter some impurities with large particles, and then enter the filter screen, because the diameter of the filter screen is small, it can play the role of filtering fine impurities, and after double filtration, the clean liquid will be discharged from the outlet.

The components of the backwash filter are carbon steel barrel body, wedge-shaped stainless steel strip filter screen, butterfly valve, and sewage device.

The components of the self-cleaning filter are the main components such as the driving mechanism, the control pipeline (including the differential pressure switch), the main assembly, the filter element assembly, the cleaning mechanism, and the connecting flange.

When the backwash filter is working normally, the butterfly valve is open, the blowdown is closed, and the internal dirt is from the inlet through the filter screen and out of the outlet, but these need to be set manually.

The filter inside the self-cleaning filter has an electric controller, a sewage valve, etc., after a series of precision operations, it can realize automatic cleaning and sewage discharge, and the internal structure of the two is different, and the steps required for sewage discharge are completely different.

Washable Filters: How do backwash filters and self-cleaning filters work?

The best filter should be the automatic backwash filter compared with other non-automatic, because automatic can avoid due to the filter in the corner or water meter room, kitchen cabinet and other corners, because you don't check often, automatic is more convenient than you go to see it in a few days, worry-free.

In addition, the difference between recoil and general self-cleaning is that the recoil is rinsed from the inside of the filter to the outside, which can be cleaner than the direct appearance of the flush, a bit like the feeling of rinsing a shaver after shaving. At the same time, the original sewage is discharged with a siphon, which can increase the water pressure and achieve the effect of high-pressure flushing.

In addition, automatic backflushing, it is not necessary to bring a motor and an external power supply. Eco's EASF1 does not need to be used, it is safe and convenient to use dry electricity, not to connect electricity. In addition, I can set the time of the cleaning for 1-30 days.

The internal structure of the backwash filter is composed of multiple filter elements, and the rotating mechanism will flush each filter element during backwashing, and all the filter elements will be cleaned in one cycle, and the pressure will return to normal. The internal structure of the self-cleaning filter is that there is a steel brush in the middle to clean the filter element, and the steel brush keeps rotating until the pressure difference returns to the initial pressure difference and stops cleaning, I hope it can help you!

Backwash filters and fully automatic backwash filters.

What is a backwash filter? Compared with ordinary filters, the backwash filter has the function of automatic drainage, for example, the ordinary filter intercepts impurities through the filter screen, which needs to be cleaned regularly, but the backwash filter has the function of automatically identifying impurities and can automatically remove them. The backwash filter is a kind of precision equipment that uses the filter screen to directly intercept impurities in the water, remove suspended solids and particulate matter in the water, reduce turbidity, purify water quality, reduce the generation of fouling, bacteria and algae, rust and so on, so as to purify water quality and protect the normal operation of other equipment in the system.

The water enters the self-cleaning filter body from the water inlet, and due to the intelligent (PLC, PAC) design ridge, the system can automatically identify the degree of impurity deposition and signal the sewage valve to automatically discharge the water.

The automatic backwash filter overcomes many shortcomings such as small dirt holding capacity of traditional filter products, easy to be blocked by dirt, the filter part needs to be disassembled and cleaned and the filter status cannot be monitored, and has the function of filtering the raw water and automatically cleaning and discharging the filter element, and the system has uninterrupted water supply when cleaning and sewage, and the working state of the filter can be monitored, and the degree of automation is very high. It covers the needs of various filtration ratings from 10um to 3000um, and provides customers with a variety of water filtration equipment. The automatic backwash filter can be used for the filtration of industrial water, seawater, food and pharmaceutical and other light chemical industry wastewater, circulating water, as well as emulsion regeneration, waste oil, liquid raw materials and other filtration treatments.

In the metallurgical industry and petrochemical industry and power plant water supply and drainage and circulating water system and chaotic seepage involving liquid medium filtration and other processes, the application of automatic backwash filter is also becoming more and more extensive, China's modern metallurgical enterprises introduced continuous casting water system, blast furnace water system, hot rolling with high-pressure water descaling system, emulsion system and closed water circulation system, liquid media filtration system have a large number of automatic backwash filters. The equipment has been debugged before leaving the factory, and the user can run it directly when it is in use. When the operating parameters of the equipment cannot meet the user's requirements, the user can adjust the parameters according to the actual working conditions, and choose manual control and automatic control mode accordingly.

When running for the first time, the following steps should be followed: check if the filter is in working order; Check whether the connections of the filter are firm; Check that the part of the filter electric control box should be dry; When the power is turned on, the green power indicator lights up, which means that the electronic control part of the filter is in normal working condition and the equipment can be put into trial operation.

When plugging in the power supply, attention should be paid to keeping the hands dry, and at the same time, the electronic control part should be kept dry during the working process of the filter, and no water should enter the inside of the electric control.
